Executive Summary

The United States (US) Army Corps of Engineers (USACE) Baltimore District on behalf of the 

Army National Guard (ARNG)-Installations & Environment Division, Cleanup Branch contracted 

AECOM Technical Services, Inc. (AECOM) to perform Preliminary Assessments (PAs) and Site 

Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) 

Impacted Sites at ARNG Facilities Nationwide. The ARNG is assessing the potential exposure to 

humans and the effect on the environment related to processes at facilities that used per- and 

poly-fluoroalkyl substances (PFAS) (a suite of related chemicals), primarily in the form of aqueous 

film forming foam (AFFF) released during firefighting activities or training, although other PFAS 

sources are possible. 

AECOM completed a PA for PFAS at the California Army National Guard (CA ARNG) Camp San 

Luis Obispo (Camp SLO) in San Luis Obispo County, California, to assess potential PFAS release 

areas and exposure pathways to receptors. The performance of this PA included the following 

tasks: 

• Reviewed available administrative record documents and Environmental Data Resources,

Inc. (EDR) report packages to obtain information relevant to potential PFAS releases

• Conducted a 1-day PA site visit on 22 May 2018

• Interviewed current CA ARNG personnel during the site visit including CA ARNG

environmental managers and operations staff; and, the California Department of Forestry and

Fire Protection services (CDF - known as CAL FIRE) representatives

• Completed visual site inspections at known or suspected PFAS release locations and

documented with photographs

• Identified areas of interest (AOI) and developed a preliminary conceptual site model (CSM)

to summarize potential Source-Pathway-Receptor linkages of potential PFAS in soil,

groundwater, surface water, and sediment for each AOI

Six AOIs related to potential PFAS releases were identified at Camp SLO during the PA. The AOIs 

are shown on Figure ES-1 and described in Table ES-1 below:

Based on documented PFAS releases at these AOIs, there is potential for exposure to PFAS 

contamination in surface soil and intermittent surface water and sediments to site and construction 

workers and trespassers via ingestion and inhalation, subsurface soil to site and construction 

workers via inhalation, and groundwater to residents via ingestion. The preliminary CSM for Camp 

SLO is shown on Figure ES-2.

1. Introduction

1.1 Authority and Purpose

The United States (US) Army Corps of Engineers (USACE) Baltimore District on behalf of the 

Army National Guard (ARNG)-Installations & Environment Division, Cleanup Branch contracted 

AECOM Technical Services, Inc. (AECOM) to perform Preliminary Assessments (PAs) and Site 

Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) 

Impacted Sites at ARNG Facilities Nationwide under Contract Number W912DR-12-D-0014, Task 

Order W912DR17F0192, issued 11 August 2017. The ARNG is assessing potential effects on 

human health related to processes at their facilities that used per- and poly-fluoroalkyl substances 

(PFAS) (a suite of related chemicals), primarily releases of aqueous film forming foam (AFFF) 

although other sources of PFAS are possible. In addition, the ARNG is assessing businesses or 

operations adjacent to the ARNG facility (not under the control of ARNG) that could potentially be 

responsible for a PFAS release. 

PFAS are classified as emerging environmental contaminants that are garnering increasing 

regulatory interest due to their potential risks to human health and the environment. The regulatory 

framework at both federal and state levels continues to evolve. The US Environmental Protection 

Agency (USEPA) issued Drinking Water Health Advisories for PFOA and PFOS in May 2016, but 

there are currently no promulgated national standards regulating PFAS in drinking water and the 

contaminant is an emerging contaminant. In the absence of federal maximum contaminant levels, 

some states have adopted their own drinking water standards for PFAS. On 13 July 2018, under 

the authority of the Deputy Director of the Division of Drinking Water, California issued drinking 

water notification levels of 14 parts per trillion (ppt) for PFOA and 13 ppt for PFOS. Notification 

levels are nonregulatory health-based advisory levels established for contaminants in drinking 

water for which maximum contaminant levels have not been established. 

This report presents findings of a PA for PFAS at California Army National Guard (CA ARNG) at 

Camp San Luis Obispo (Camp SLO) in San Luis Obispo County, California, in accordance with 

the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as 

amended, the National Oil and Hazardous Substances Pollution Contingency Plan (40 Code of 

Federal Regulations CFRPart 300), and USACE requirements and guidance. 

This PA documents the known fire training areas (FTAs) as well as additional locations where 

PFAS may have been released to the environment at Camp SLO. The term PFAS will be used 

throughout this report to encompass all PFAS chemicals being evaluated, including PFOS and 

PFOA, which are key components AFFF.

1.2 Preliminary Assessment Methods

The performance of this PA included the following tasks: 

• Reviewed available administrative record documents and Environmental Data Resources,

Inc. (EDR) report packages to obtain information relevant to potential PFAS releases

• Conducted a 1-day PA site visit on 22 May 2018

• Interviewed current CA ARNG personnel during the site visit including CA ARNG

environmental managers and operations staff; and, the California Department of Forestry and

Fire Protection services (CDF - known as CAL FIRE) representatives

• Completed visual site inspection (VSI) at known or suspected PFAS release locations and

documented with photographs

1.4 Facility Location and Description

Camp SLO is located in southern San Luis Obispo County in central California, approximately 6.5

miles east of the Pacific Ocean and 5 miles northwest of the city of San Luis Obispo, California 

(Figure 1-1). The installation occupies approximately 5,320 acres along the northern and 

southern sides of and adjacent to Highway 1, extending from Cerro Remualdo and Chumash 

Peak in the southern portion, to the foothills of the Santa Lucia Range in the northern portion of 

the facility. 

Camp SLO was originally established by California in 1929 on 5,800 acres as a National Guard 

Training Camp, known as Camp Merriam. In 1940, Congress authorized funds for the Army to 

lease about 44,000 acres of ranch lands and eventually purchased the leased parcels and 

additional lands in 1943. Construction of the Main Garrison began on 15 November 1940. Camp 

SLO officially began its mission as a training site in March 1941 (Camp Roberts Historical 

Museum). 

From 1939 to 1945, Camp SLO served as a CA ARNG training site for horse cavalry, and the 

Navy also likely used the area for live-fire training activities during World War II. In 1947, control 

of the Camp reverted to CA ARNG, and the US Army operated the Southwest Signal Center at 

Camp SLO in 1951 during the Korean conflict. Part of Camp SLO remained under federal control

until 1 July 1965, when the entire property was returned to State control. Approximately 4,685 

acres were relinquished to the General Services Administration (GSA) in 1965. The GSA then 

transferred the property to other agencies and individuals beginning in the late 1960s through the 

1980s. Most of the property was transferred to California Polytechnic State University (Cal Poly) 

and Cuesta College for educational use. A total of 5,880 acres were retained by the CA ARNG

for the purpose of developing a training facility for CA ARNG. 

Camp SLO supports federal and state military training activities and serves as a year-round 

training site for the CA ARNG. Access to the site is restricted and inaccessible to the general 

public in some areas. The installation’s mission is to maintain and allocate training areas, 

airspace, facilities, and ranges, in order to support CA ARNG. Additionally, the installation 

provides quality of life, logistical support to training units, and administrative services. Future land 

use is not anticipated to change. 

1.5 Facility Environmental Setting

Camp SLO is located on the western slopes of the Santa Lucia Range, approximately 4.5 and 6.5

miles east of Morro Bay and the Pacific Ocean, respectively. The terrain in and around the facility 

is primarily the foothills of the Santa Lucia Range, which exhibits high relief with grasslands, rolling 

hills, and canyons. The facility is bounded to the north by Los Padres National Forest in the Santa 

Lucia Mountains and to the south by Cerro Romauldo and Chumash Peak, two hills that are a 

part of the Nine Sisters Peaks. The elevation of the facility ranges from approximately 190 to 

2,440 feet above mean sea level (msl), with elevation increasing from west to east.

1.5.1 Geology

Camp SLO lies within the Pacific Border physiographic province, California Coast Ranges. The 

California Coast Ranges are predominantly composed of late Mesozoic and Cenozoic 

sedimentary rocks (Franciscan Complex) formed from subduction of the Pacific Plate under the 

North American Plate. The landscape also displays lateral deformation from the San Andreas 

Fault System, which dominates the California Coast Ranges, resulting in parallel sequences of 

linear ridges and valleys (Fuller, M. et al., 2015). The various geologic formations and features at

Camp SLO and within the surrounding area are presented in Figure 1-2. 

The majority of Camp SLO lies on the Franciscan Complex, which is a mélange of Cretaceous to 

Jurassic-age fragmented rock masses in a sheared matrix of argillite and crushed 

metasandstone. Individual rock masses within the mélange range in size from less than a meter 

to kilometers. Blocks large enough to map include sandstone and shale in the western portion of 

the facility and metavolcanic rocks in the south and central portions of the facility. The sandstone 

and shale are made up of fine- to medium-grained greywacke sandstone interbedded with shale 

and siltstone. The metavolcanic rocks are primarily greenstone metamorphosed from basalt. The 

Jurassic-age serpentinized ultramafic rocks lie on the north side of the Franciscan Complex, 

bounded on both sides by faults and composed of pervasively-sheared serpentinite (Wiegers, 

M.O., 2010).

Oligocene and Miocene-aged rocks unconformably lie above the Franciscan Complex and are 

composed of the Rincon Shale, the Obispo Formation, and the Monterey Formation. The Rincon 

Shale is located on the east side of the Chorro Reservoir and comprises primarily siltstone and

silty claystone and locally contains zones of dolomite and arkosic sandstone. The Obispo 

Formation lies above the Rincon Shale to the northeast and is composed primarily of fine- to 

coarse-grained vitric tuff. The Monterey Formation begins just north of the Chorro Reservoir and 

is composed of laminated to thin-bedded shale, siliceous claystone, and soft diatomaceous 

siltstone (Wiegers, M.O., 2010).

Camp SLO, San Luis Obispo County, California

Holocene and Pleistocene landslide deposits overlie the Monterey Formation and occupy the 

northeastern portion of the facility. The landslide complex is deeply dissected in a serpentinite 

and diabase dike-and-sill complex on the southwest side of the Santa Lucia Range (Wiegers, 

M.O., 2010). The Oceanic Fault is a reverse fault that strikes west-northwest, stretches from

Santa Maria to its convergence with the San Simeon Fault just northwest of San Simeon, and

runs through the northern side of the landslide deposits. Additional, smaller faults appear in the

area as right-lateral, strike-slip faults with near vertical fault planes.

The Morro Rock – Islay Hill Volcanic Intrusive Complex forms a series of volcanic plugs and lava 

domes known as the Nine Sisters Peaks. Two of the peaks (Cerro Romauldo and Chumash 

Peak) are located in the southern side of Camp SLO along the facility boundary. The Morro Rock 

– Islay Hill Volcanic Intrusive Complex (Oligocene) is composed of porphyritic dacite, with flow

banding common (Wiegers, M.O., 2010). The Intrusive Complex penetrates the Franciscan

Complex, with the Franciscan Complex mélange on the slopes of Cerro Romauldo, and the

Franciscan Complex sandstone and shale on the north slope of Chumash Peak.

The westernmost portion of the site is composed of young Holocene to late Pleistocene alluvial 

flood-plain deposits of unconsolidated sand, silt, and clay. These alluvial deposits are observed 

as thick as 50 feet and found along Chorro Creek as well as several other unnamed streams 

traversing the facility. The remaining unconsolidated overburden is also observed as thick as 50 

feet and is primarily composed of silt and clay terrace deposits.

1.5.2 Hydrogeology

Regional groundwater flow is to the west towards the Chorro Valley Groundwater Basin and Morro 

Bay. Groundwater in the region is found in Pleistocene to Holocene age surficial deposits. The 

primary source of groundwater extracted from wells in the region is from generally thin alluvium 

deposits that blanket the San Luis Obispo Creek watershed. Recharge to the groundwater basin 

is from applied irrigation water, influence from streams, and infiltration of precipitation on the valley 

(State of California, 2004).

Both the city of San Luis Obispo and San Luis Obispo County extract groundwater from the San 

Luis Obispo Valley Groundwater Basin, located to the south and east of the facility. The northwest 

boundary of the San Luis Obispo Valley Groundwater Basin contacts the impermeable Franciscan 

Group rocks approximately 1 mile south of the facility. Domestic and public supply wells are 

located within 2 miles of the facility (Figure 1-2).

Groundwater in the unconsolidated deposits at Camp SLO tends to follow topography and flows 

generally to the southwest in areas north of Highway 1. South of Highway 1, groundwater flows 

generally towards Chorro Creek in a northwest or southwest direction.

Camp SLO is not located on a principal aquifer system, and the underlying bedrock formations 

are not generally recognized as water bearing. Groundwater is primarily found in the Holocene 

to late Pleistocene alluvial flood-plain deposits. Yields from the alluvial deposits are generally 

from 20 to 300 gallons per minute (gpm), and yields from the terrace deposits are generally around 

20 gpm (State of California, 2004).

1.5.3 Hydrology 

The majority of Camp SLO is within the Morro Bay Watershed, which is located in the central area 

of coastal San Luis Obispo County and covers an area of approximately 46,598 acres (Morro Bay 

National Estuary Program [MBNEP], 2013). Surface water features and watersheds are 

presented in Figure 1-3. 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

13

The watershed has two major sub-watersheds that drain to Chorro and Los Osos Creeks, both of 

which drain to the Morro Bay Estuary and then to the Pacific Ocean. The Chorro Creek subwatershed, within which the majority of Camp SLO is situated, accounts for about 60 percent of 

the total land area draining to the Morro Bay Estuary (MBNEP, 2013). Relatively small land surface 

areas along the southeastern and eastern margins of Camp SLO are situated within the Upper 

and Lower San Luis Obispo Creek Watersheds, respectively. Water in the Morro Bay watershed 

is managed by the City of Morro Bay, Los Osos Community Services District, Golden State Water 

Company, and S&T Mutual Water Company (MBNEP, 2013). 

Regional surface water features include Chorro Creek, which passes through the facility, and

Chorro Reservoir, which is located in the northeastern portion of the facility. The Chorro Creek is 

a 2002 303(d)-listed impaired waterbody that flows into a Marine Protected Area (Morro Bay State 

Estuary, and MBNEP) and is designated as a critical coastal area along the central coast of 

California (California Coastal Commission, 2016). Sixty percent of the Chorro Creek watershed 

is classified as rangeland, and 20 percent is brushland. 

Chorro Creek is regionally used for domestic and municipal water supply and agricultural supply 

purposes. Chorro Reservoir is used for hydroelectric power generation and recreation. It is owned 

by Camp SLO and operated by the California Men’s Colony (CMC). The reservoir was constructed 

in 1941 to store runoff water for Camp SLO and was historically used for the facility’s water supply 

along with three base wells. The three water wells at Camp SLO that were historically used for 

potable water purposes include Well No’s 1, 2, and 3 (see Figure 1-2). Well No. 1 is 12-inches in 

diameter and approximately 51 feet below ground surface (bgs). No construction information is 

available for Wells No. 2 and 3 (Geosystem, 1996). According to the Camp SLO Environmental 

Scientist, the wells are without pumping equipment and are currently managed by San Luis 

Obispo County, who use the wells to gauge and monitor groundwater basin conditions (i.e. depth 

to groundwater).

The potable water supply for Camp SLO is from waters piped to the facility from Whale Rock 

Reservoir, which is situated approximately 11 miles to the northwest of the facility. The water from 

Whale Rock is piped to a water treatment facility located at Chorro Reservoir, where after 

treatment, water is distributed to the Camp SLO cantonment areas. The treatment facility is 

managed by the CMC. The CMC and Cuesta College receive State Water through the Chorro 

Valley Turnout. The Turnout conveys State Water from the Coastal Branch of the State Water 

pipeline to the CMC (MBNEP, 2013). Potable water for the coastal town of Los Osos (4 miles 

downgradient of Camp SLO) is provided from several groundwater wells. 

The main surface water drainage feature for Camp SLO is Chorro Creek, which begins to the 

north of the facility, passes through the center of the facility in a northeast-southwest direction, 

and exits the facility on the southwest boundary. Chorro Creek is a fifth order stream and has 

approximately 14.2 miles of blue line stream (Coastal San Luis Resource Conservation District

[CSLRCD], 2001). Tributaries of Chorro Creek at and within the vicinity of Camp SLO are 

intermittent and flow only when precipitation is sufficient. Chorro Creek flows into the Chorro 

Reservoir, after which it passes beneath Highway 1 and flows through all of the cantonment areas 

of Camp SLO. Downstream of Camp SLO, Chorro Creek converges with the Morro Bay Estuary 

located approximately seven miles west of the facility. Chorro Creek is fed by numerous small 

tributary streams that flow through the facility. These include Dairy Creek, which originates just 

north of the property boundary, cuts across the northwest corner of the facility, parallels the 

western property boundary until it converges with Chorro Creek in the southern portion of the 

facility. 

According to the National Wetlands Inventory by the US Fish and Wildlife Service, emergent or 

forested/shrub wetlands are located at Camp SLO around Chorro Reservoir. Figure 1-3 depicts 

the locations of the wetland areas. The wetlands in the reservoir area are generally noncontiguous, each less than about 2 acres in extent. Forested/shrub and emergent wetlands areas

exist in nearly all areas adjacent to Chorro Creek and its tributaries, within the various creeks’ 

stream banks. 

There are two oil/water separators at Camp SLO. One separator is located at the Camp SLO 

Directorate of Public Works yard and the other at FMS-19, the field maintenance shop. The only 

other infrastructure includes a series of above ground culverts in the cantonment.

1.5.4 Climate 

The climate at Camp SLO is considered Mediterranean, with a subtropical dry summer, abundant 

sunshine, and modest precipitation in winter. Camp SLO has seasonally warm summers and mild 

winters. The average temperature is 59 degrees Fahrenheit (°F), with summer highs of 75.3 °F 

and winter lows of 43.8 °F (National Oceanic and Atmospheric Administration [NOAA], 2018). 

Average annual precipitation is 23.12 inches.

1.5.5 Current and Future Land Use

Camp SLO serves as a year-round training site for the CA ARNG. The cantonment area of the 

facility is developed with numerous buildings and related infrastructure including paved and 

unpaved roadways and parking areas. The cantonment area occupies a small percentage of the 

total area controlled by the CA ARNG, the other, much larger lands of which are occupied by and 

used as training ranges. The ranges are generally in vegetated sloping areas, mostly to the north 

of Highway 1. Access to lands under Camp SLO purview is restricted and inaccessible to the 

general public in most areas. 

The installation’s mission is to maintain and allocate training areas, airspace, facilities, and ranges 

in order to support CA ARNG. Additionally, the installation provides quality of life, logistical support 

to training units, and administrative services. Tenants include CAL FIRE, CAL Trans, CA 

Conservation Corps, and CA Specialized Training, Inc. Future land use is not anticipated to 

change.

2. Fire Training Areas

Four FTAs were identified during the PA; two had potential PFAS releases, and two did not have 

reported releases. A description of the FTAs is presented below, and the locations of the FTAs

are shown on Figure 2-1. Interview records and photographs are included in Appendix B and 

Appendix C, respectively.

2.1 Former CAL FIRE Fire Training Area

2.1.1 Description and Operational History 

The former CAL FIRE FTA is located in the southwest portion of the facility, north of the 

intersection of Tehama and Mono Avenues, and south of Chorro Creek (Figure 2-1). The 

approximate geographic coordinates and elevation of the central portion of the FTA is 

35°19'23.67"N;120°44'48.62"W’; and 223 feet msl, respectively. The parcel is approximately 1.8 

acres in size. 

Various sets of aerial photographic images from 1949 through to 2017 were reviewed for this PA. 

The earliest available photograph shows a large rectangular building occupying the southern 

portion of the FTA, in an area adjacent to Tahoma Avenue. Areas to the east and south are 

occupied by numerous structures, the smaller structures of which are likely hutments. Chorro 

Creek is visible to the north and east of the area. By 1956, the hutments were removed, and most 

of the larger buildings remained. Through the 1970’s, numerous larger structures were removed, 

and by 1981, nearly all of the structures at and within the vicinity of the FTA were removed with 

exception of a small rectangular shaped structure situated in the northern portion of the FTA, near 

the top of the Chorro Creek bank. Agricultural fields are visible in a 1989 photograph to the east 

and south of the FTA. By 1994, numerous small features, some of which appear to be concrete 

pads and possibly smaller structures, are visible in the northern half of the FTA, and several 

structures appear to the east of the FTA. Subsequent photographs reviewed through to 2017 

indicate that land use remained generally consistent with that noted in the 1994 photograph.

According to the Camp SLO Site Agreement Manager, CAL FIRE historically conducted short 

training exercises at the former CAL FIRE FTA. Additionally, the CAL FIRE Team Chief and a Fire 

Captain interviewed during the PA site visit indicated that fire training was conducted at the parcel

once per year from about 1995/1996 to 2010/2011. As part of the training activities, props were 

used to train the fire fighters on how to apply foam. It was reported that one 5-gallon bucket of 3% 

AFFF was used during each training session. During the training sessions, AFFF was expelled 

through a nozzle at the various props and the small rectangular concrete structure described 

above. No information is available as to whether actual fires were set. No information is available 

on the final disposition of AFFF after the training was completed, and no remediation activities 

have occurred at this location.

2.1.2 Current Use, Topography and Surface Features

The former CAL FIRE FTA is currently used once per year by Phillips 66 Company (Phillips) under 

a one-day-use license granted by the California Military Department, giving Phillips the permission 

to use the property for the purpose of fire suppression/prevention training. According to the Camp 

SLO Site Agreement Manager and documents provided, the area was annexed to the California 

Specialized Training Institute (CSTI) for their exclusive use on 28 May 1997. Copies of the 

licenses and agreements are presented in Appendix A. CSTI was observed to be operating a 

specialty hazardous materials training area to the east and adjacent to the former CAL FIRE FTA. 

A chain link fence was observed to separate the two parcels. CSTIs’ use of this adjacent area is 

described in more detail in Section 3.5. 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

Various industrial-type props and an above-ground Liquified Petroleum Gas tank with fuel feeder 

lines leading to the props were observed during the PA VSI of the former CAL FIRE FTA area (see 

Appendix C for photographs). According to the CSTI Site Manager interviewed, Phillips 

conducted a training event at the former CAL FIRE FTA parcel on 21 May, the day before our PA 

site visit. Fire retardant residues were observed on the ground surface within and around a burn 

pit situated near the center of the FTA. Additionally, a total of 21 empty Ansul fire extinguishers 

were observed to be stored in the concrete structure situated in the northern portion of the FTA. 

A label on the extinguishers indicated that the extinguishers are to be filled only with “Purple-K”, 

a dry-chemical fire suppression agent. Purple-K does not contain PFAS. According to the CSTI 

manager, AFFF was not used during the training event, and based on his recollection, was not 

used during past training sessions. No other information pertaining to the training is available.

The ground surface of the former CAL FIRE FTA was observed to be relatively flat and with gravel 

cover. Areas to the north and northeast were observed to be heavily vegetated with trees and lowlying brush. Surface elevations decline radially to the northeast, north, and northwest in the 

direction of Chorro Creek. The slopes of the Creek adjacent to and in the vicinity of the area are 

generally steep and heavily vegetated. The small rectangular structure visible in photographs 

since as early as 1949 was observed to have a partially buried basement. 

2.1.3 Surface Water and Groundwater

Surface water in the vicinity of the former CAL FIRE FTA flows towards Chorro Creek, radially to 

the northeast, north, and northwest, in a direction consistent with surface topography. The 

concrete cinder-block structure used for fire training purposes is approximately 200 feet to the 

south/southwest of Chorro Creek’s flow-line. Flowing water was observed in the Creek at the time 

of the PA site visit. A waste water treatment plant (WWTP) operated by the CMC is immediately 

downstream of the area, followed by generally open areas with some agricultural fields situated 

adjacent to the Creek, the Morro Bay Estuary, and finally, the Pacific Ocean. The creek banks 

adjacent to Chorro Creek are classified by the U.S. Fish and Wildlife Service as wetlands.

Groundwater beneath the area flows regionally to the west and locally to the northwest, towards 

Chorro Creek. Camp SLO water wells closest to the FTA are Well No.’s 2 and 3, both of which 

are hydraulically upgradient at a distance of approximately 3,000 and 1,300 feet east and south 

east of the area, respectively.

2.2 Former META Yard Fire Training Area

2.2.1 Description and Operational History 

The Motorized Equipment Training Academy (META) yard was used by Caltrans for equipment 

training purposes and as a vehicle washing and maintenance yard (Geosystems, 1996). The

parcel was leased to Caltrans by the CA ARNG. The Caltrans tenancy lasted until April 1995, after 

which the area was leased to Operating Engineers’ Training Trust, the current occupants of the 

area. The META yard is located near Camp SLO’s southern property boundary, to the east of the 

former Sutter Avenue Landfill (SALF), and to the southwest of the intersection of Sutter Avenue 

and O’Connor Way. The approximate geographic coordinates and elevation of the central portion 

of the parking lot of the yard is 35°19'09.98"N;120°44'22.52"W; and 236 feet msl, respectively

(Figure 2-1). Fire training was reported to occur in the eastern portion of the approximately 1.5-

acre lot. The area was not visited during the PA site visit, as the reported use of the area for fire 

training purposes was conveyed subsequent to the PA site visit. 

Based on a review of historic aerial photographs and information and documents provided by the 

Camp SLO Environmental Manager, the parking lot area, and more specifically, the eastern 

portion of the parking lot, was used for fire training in May 2005. The area may have also been 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

20

used for fire training in the 1980s and possibly as early as 1978. A 1978 photograph and 

subsequent photographs reviewed through to 2017 indicate an approximately 60-foot-diameter

circular feature in the eastern part of the lot, at the entrance to the lot from O’Connor Way and

south of what appears to be a small shed. The surface of the soil appears to be consistently 

discolored in the area in each of the photos reviewed since 1978. Aside from the visual aspects 

of the feature interpreted from photographs, no information is available regarding which entity 

may have used the area and what the area may have been used for during this earlier period of 

time. 

Not much information about the actual fire training events is available, however, paperwork 

describing reported training burns at waste and brush piles and preparations for an event that 

occurred in 2005 was available and is included in Appendix A. A brief summary of the documents 

is described below.

2.2.1.1 Training Burns at Waste and Brush Pile

A letter from the Air Pollution Control District, County of San Luis Obispo dated 28 June 1989 to 

CAL FIRE references fire training burns at a waste disposal site (landfill) and brush pile behind 

the Cuesta College campus, near the (former) Caltrans yard. The letter indicates that inspections 

of the pile noted various municipal type wastes that included plastic coated wires and large rolls 

of carpet. All materials documented in the letter with exception of wood materials were requested 

by the inspectors to be removed from the piles prior to burning. Some of these materials may 

have been removed prior to the burns; however, post-burn inspections noted the presence of 

some of the same materials in the ash. 

No information pertaining to the specifics of the fire training are available, and no information is 

available on whether AFFF was used. 

2.2.1.2 2005 Fire Training Session

In coordination with Camp SLO Environmental Compliance (EC) and CAL FIRE/San Luis Obispo 

County Fire Department, CAL FIRE conducted a one-time fire training session on 11 May 2005 in 

the east parking lot of the META yard. According to a 14 March 2005 memo from Camp SLO EC 

to CAL FIRE that detailed and formally requested the exercise, the purpose of the exercise was 

to train firefighters on how to apply foam to a large tank truck trailer, simulating a highway type 

emergency involving an over-the-road tanker carrying flammable liquid. The memo stated that 

Ansulite AFFF would be used at a 6% application rate using 30 gallons of foam per 500 gallons 

of water (the capacity of each fire engine). Based on a proposed eight drills, a total of 4,000 

gallons of water and 240 gallons of foam would be used. A Material Safety Data Sheet for the 

foam and a Nature of Discharge Report were also submitted with the memo. A request was made 

by Camp SLO EC to capture runoff generated by the activities and discharge it to the WWTP

operated by CMC, not to surface water. CMC was to be notified first.

No information is available as to whether actual fires were set, and no information is available on 

the final disposition of AFFF after the training was completed. There is no stormwater drainage 

infrastructure in the area where the training event occurred. If the training event took place, the 

plan was to use AFFF on pavement, contain it, and process the recovered material at the WWTP

(however, it should be noted that the WWTP did not become operational until approximately late 

2007). Thus, if the applied foam were not contained, runoff from the area is via a small ditch 

flowing south then southwest to a tributary that then flows northwest to Chorro Creek (Figure 2-

1).

2.2.2 Current Use, Topography and Surface Features

Based on review of aerial photographs, the generally rectangular parking lot in which the training 

occurred is relatively flat and covered in gravel. Surface elevation slopes to the west, with 

elevations at the eastern and western portions of the lot at approximately 238 and 234 feet above 

msl, respectively. Two larger structures occupy the northeastern corner of the parking lot. Parking 

lot areas not covered in gravel within and around the parcel are grass covered. The southwestern 

corner of the parking lot borders the northeastern corner of the SALF. Recent information from 

CA ARNG indicates that the two structures and a carport were burned as part of a California Arson 

Investigators' Association training event on 25 September 2018. It is unknown if AFFF were used 

during the training.

2.2.3 Surface Water and Groundwater

Surface water either evaporates, percolates into the ground, and/or flows generally to the east, 

towards Poison Oak Creek. The tributary creek is situated at the base of low-lying hills to the 

southeast of the FTA at a distance of approximately 2,000 feet directly east of the area. The 

tributary joins Chorro Creek immediately east of the CMC WWTP (see Figure 1-3).

Groundwater beneath the area flows regionally to the west and locally to the east towards Poison 

Oak Creek, a tributary to Chorro Creek. Camp SLO water wells closest to the FTA are Well No.’s 

2 and 3. Well No. 2 is located hydraulically upgradient of the area at a distance of approximately

600 feet. Well No. 3 is situated down to cross-gradient of the area to the northeast at a distance 

of approximately 1,400 feet. Ten groundwater monitoring wells have been installed to monitor

conditions at and within the vicinity of the SALF. Several wells continue to be gauged and 

monitored on a semi-annual basis in accordance with the Central Coast Regional Water Quality 

Control Board. The majority of these wells are downgradient of the FTA. The SALF has a grass 

cover which has been approved by the CENTRAL Coast Regional Water Quality Control Board 

to be replaced by an artificial turf cover due to an ongoing and persistent ground squirrel 

infestation. The project is to be started and completed the year 2020.

2.3 CAL FIRE San Luis Obispo Unit Tactical Drill Grounds Training 

Site

CAL FIRE currently operates the San Luis Obispo Unit Tactical Drill Grounds Training Site in the 

southwestern portion of Camp SLO. The approximately 4-acre facility is bordered to the west by 

the WWTP operated by the CMC, to the north by Tehama Avenue, and to the east and south by 

open areas. The approximate geographic coordinates and elevation of the central portion of the 

parking lot are 35°19'20.02"N;120°44'57.68"W; and 214 feet msl, respectively (Figure 2-1).

According to a Notice of Exemption (NOE) document (Appendix A) dated 7 October 2016, CAL 

Fire/San Luis Obispo County Fire leases the drill grounds site from the CA ARNG. Background 

information provided in the NOE document describes the site as a drill ground facility that consists 

of two permanent structures and a number of steel shipping containers situated in a variety of 

configurations to provide fire department training including a rope rescue tower, burn building, 

multi-story burn building, active shooter, and storage. The facility was observed during the PA VSI 

of the area to generally have the infrastructure documented in the NOE. Numerous larger 

vehicles, likely used as props, were also observed. Ground cover was observed to be a mix of 

concrete and gravel. 

According to the CAL FIRE training personnel interviewed, only water is used during fire-related 

training sessions conducted at the drill grounds. No other information was available regarding the 

training.

2.4 Prescribed Building Burns by CAL FIRE for Structural Fire 

Training

In coordination with Camp SLO EC, CAL FIRE has historically and more recently conducted 

structural fire training at Camp SLO using old buildings no longer used by the facility. The various 

prescribed burn events were permitted through the County of San Luis Obispo Air Pollution 

Control District prior to the activities. 

Two burned out structures were observed during the PA site visit. The location of the burned 

structures and photographs of the burned building remnants are presented in Figure 2-1 and 

Appendix C, respectively. In late September 2018, subsequent to the PA site visit, the Camp SLO 

Environmental Manager reported that CAL FIRE burned 7 additional structures for fire training 

purposes including three structures at area 2.2, the former META training yard.

According to the CAL FIRE Team Chief and CAL FIRE Captain, water was used during these 

types of structural fire training sessions, and AFFF was not used during the training events. No 

evidence of AFFF use was observed during the PA VSI of the area. No other information was 

available regarding the structural fire training burns. The ash observed in the footprints of the 

March 2018 CAIA training event and during the May 2018 PA site visit were removed from Camp 

SLO in October 2018.

There are records, i.e., email traffic from former Wildlife Biologist Jodie Olson to and from Senior 

Environmental Scientist John A. Morrow, dated Spring of 2007, concerning a potential Cal Fire 

training activity at this parcel, involving the usage of fire-fighting foam.

3. Non-Fire Training Areas

Two non-FTA where PFAS were known to be released and several other non-FTAs were

evaluated during the PA. Description and their locations are presented below and shown on 

Figure 3-1. Interview records appear in Appendix B. Photographs appear in Appendix C. 

Non-FTAs where PFAS were potentially released to the environment are CAL FIRE Cuesta Camp 

Tenant and the O’Sullivan Airfield, which includes an airfield shed where AFFF is stored. 

Other features investigated during the PA that were determined to be unlikely PFAS releases

include the following: 

• Former U.S. Army Air Strip (Historic Camp SLO Airfield)

• Closed Landfills:

─ Sutter Avenue Landfill

─ Kansas Avenue Landfill

─ Story Park Landfill

─ Pennington Creek Landfill

• California Specialized Training Institute Training Area

• CMC Wastewater Treatment Facility

• Former Paint Booth in Building 1341

3.1 CAL FIRE Cuesta Camp Tenant

Based on information obtained during the PA, AFFF was released sometime in 2014 at a fueling 

station associated with the tenant CAL FIRE Cuesta Camp. The site is situated west of Diary 

Creek on the south side of Highway 1. The approximate coordinates and elevation are 

35°19'44.76"N; 120°43'57.34"W; and 274 feet msl, respectively (Figure 3-1). The facility and

location of the potential AFFF release area were not observed during the PA site visit. 

According to the CAL FIRE Chief and a CAL FIRE Captain, AFFF was released to a concrete 

covered area when hoses and possibly an empty tank, which contained AFFF, were flushed out 

with water at the Station’s bulk fueling islands that are operated by CAL FIRE. No information was 

available on the precise location of the release. The amount and percentage of AFFF released

are not known. 

The area in which the release occurred is situated approximately 700 feet to the north and 

hydraulically upgradient of Chorro Creek. Surface water flows to the south towards the Creek. 

Chorro Creek, in the vicinity of where the release occurred, flows east to west, beneath Highway 

1, through the cantonment of Camp SLO, and past the CMC WWTP. Groundwater flows locally 

to the south/southwest and regionally to the west.

No photographs were taken at this location.

3.2 O’Sullivan Airfield Shed

O’Sullivan Airfield is located in the southwestern portion of the facility, between Cuesta College 

Road and Hollister Road (Figure 3-1). The geographic coordinates are 35°19'34.43"N; 

120°44'34.75"W. 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

25

The airfield was constructed in 1940 and is currently operated by the CAARNG as a heliport. The 

heliport was constructed in the 1980s and is used infrequently, up to 20 times per year. No regular 

fueling operations occur there. The last known fueling activity at the heliport was in 2008. AFFF 

is stored inside a building (shed) adjacent to the helipad. The shed was observed during the PA 

VSI of the area to contain two Tri-Max crash carts which typically contain AFFF, three 5-gallon 

buckets of Chemguard 3% AFFF, and one 5-gallon bucket of FireAide 3% AFFF. Appendix A

includes documents pertaining to the AFFF stored. The shed is not a numbered building and is 

situated between the airfield and the Civil Air Patrol tenancy, south of Cuesta College and north 

of Achievement House. The portable units are managed by transient aviation units, and

interviewees had no direct knowledge on how they used or maintained them.

Surface water and groundwater at and within the vicinity of the shed likely flows to the 

west/southwest, towards Chorro Creek.

3.3 Former U.S. Army Air Strip (Historic Camp SLO Airfield)

The former Camp SLO Airfield was located adjacent to O’Sullivan Airfield, west of the current 

facility boundary, along the western side of Pennington Creek, and south of Route 1 (Figure 3-

1). The geographic coordinates are 35°19'47.51"N;120°44'51.39"W. 

The airfield was constructed in 1940 and used until 1965. No information obtained indicates that 

AFFF was used or stored here, and the dates of operation pre-date the use of AFFF.

3.4 Closed and Former Landfills

There are three known landfill areas at Camp SLO. Each of the landfills operated at various times 

within Camp SLOs boundaries and each are currently closed. The location of each of the landfills 

is depicted on Figure 3-1. Appendix C includes photographs of one of the landfills observed 

(SALF) during the PA site visit. None of the other landfills described below were observed during 

the visit.

Landfills are not usually a primary source of PFAS, however, materials disposed of in landfills 

containing PFAS may leach the compounds to the environment over time. Such materials may 

include residual sludge wastes from WWTP operations, used AFFF storage containers, or 

products associated with waterproofing such as uniforms or boots. 

At Camp SLO, no information obtained during the PA efforts indicates PFAS-containing materials 

were disposed of in the several landfills that operated at the facility; however, the dates during 

which some of the landfills were in use coincide with the years during which AFFF was in use at 

the facility. 

Since 1995, all waste generated at Camp SLO is transported to the Cold Canyon landfill for 

disposal. The facility is located approximately 15 miles southeast of Camp SLO. 

In addition, a former landfill, the Pennington Creek Landfill (PCLF), is located directly north of the 

northwest corner of the facility. The ownership of this property was transferred to CA State 

University, San Luis Obispo (CAL Poly) from the CA Department of the Military, sometime around 

1968.

3.4.1 Sutter Avenue Landfill

The SALF is a 5.2-acre closed Class III landfill located in the southeast corner of Camp SLO 

(Figure 3-1). The landfill is bounded by Poison Oak Creek to the southwest, Sutter Avenue to the 

north, a former California Department of Transportation facility to the north and east, and privately-

owned range land to the south. The approximate coordinates and elevation of the SALF are 35° 

19’05.52”N; 120° 44’34.75”W; and 230 feet msl, respectively. 

The SALF was operated by the CA ARNG. Disposal of waste into the SALF began between 1969 

and 1973 and continued until the mid-1980s (USACE, 1996). Disposal of municipal type waste in 

the landfill reportedly stopped in 1985 (Geosystems, 1996). A final cover system was installed in 

1996 and 1997 that included an engineered foundation layer, drainage layers, and high-density 

polyethylene membrane liners (ECM Consultants [ECM], 2016). The landfill was filled using 

trench-and-cover methods. The trenches were approximately 200 to 300 feet in length and about 

8 feet in width. The trenches were excavated to depths of 8 feet. Wastes reported to have been 

disposed of in the SALF included commercial rubbish, scrap wood, scrap metal, weapon oil, brush 

and grass clippings, and some food waste (USACE, 1996). 

It was reported that demolition debris was ignited for a fire fighter training program by CAL FIRE

staff. The debris that was ignited was reported to have been subsequently placed into the SALF 

sometime after 1985. The frequency of the fire training is not known, and it is also unknown if the 

fire training activities included the use of AFFF. As such, it is unknown if the demolition debris 

placed into the landfill contained AFFF (Geosytem Consultants, 1996). 

Several investigations were conducted at the SALF by others, mostly in 1995, and numerous 

wells were installed to assess groundwater quality conditions at and within the vicinity of the SALF. 

Ten groundwater monitoring wells associated with the pre- and post-lined landfill were monitored 

first quarterly, then semi-annually, and since as early as 1990. The SALF has confirmed releases 

of volatile organic compound constituents (ECM, 2016). 

Surface water and groundwater beneath the SALF flow in a direction to the south-southwest. 

Groundwater has historically reported to be less than 10 feet bgs during periods of high 

groundwater, and the northwest base of the landfill may have periodically been submerged 

(USACE, 1996). 

3.4.2 Kansas Avenue Landfill

The Kansas Avenue Landfill (KALF) is located to the south of Highway 1 (Figure 3-1). The landfill 

is bounded on the north by Highway 1, on the east by Oklahoma Avenue and commercial 

buildings, and on the south and west by open space. The approximate coordinates and elevation 

of the SALF are 35°19’06.51”N; 120°42’59.02”W; and 338 feet msl, respectively. 

The landfill was filled using trench-and-cover methods and was used for the disposal of primarily 

municipal waste. The landfill may also have had paint, lubricant containers, and dry cell batteries 

dumped there during a time after the Army used the landfill (USACE, 1996). The KALF was used 

from 1941 to until approximately 1956, dates which predate the use of AFFF. 

3.4.3 Story Park Landfill 

The Story Park Landfill (SPLF) is located in a clearing north of Highway 1, south of a tributary to 

Chorro Creek and Santa Cruz Road, east of Kern Avenue, and west of the CMC (Figure 3-1). 

The approximate coordinates and elevation of the SPLF are 35°19’18.82”N; 120°42’54.22”W; and 

337 feet msl, respectively. 

The only recorded uses of the landfill were in 1949 and 1969 (Geosystems, 1996). In 1949, it was 

possible that sewage treatment activities associated with the operation of an Imhoff tank occurred 

in the southeast portion of the area. The final disposition of aqueous wastes potentially generated 

is not known. In 1969, a single trench was excavated parallel and close to Chorro Creek, in the 

southern boundary of the clearing; however, little information is known concerning the use of the

trench. Soil and groundwater investigations performed in the area in 1994 did not indicate impacts 

to subsurface media. 

No information obtained indicates PFAS-related materials were disposed of in the landfill. 

3.5 California Specialized Training Institute Training Area

The CSTI is a division of the State of California, Office of Emergency Services. The facility covers 

an area of approximately 2.5 acres in the southwest portion of Camp SLO and is situated north 

of Tehama Avenue and to the east and adjacent to the former CAL FIRE FTA discussed in Section 

2.1. The approximate coordinates and elevation of the CSTI training area are 35°19’22.21”N; 

120°44’47.40”W; and 225 feet msl, respectively.

CSTI provides hazardous materials response and riot control training to law enforcement and 

emergency response agencies (Geosystems, 1996). According to CSTI’s onsite manager, the 

Camp SLO Site Agreement Manager, and documents provided, the area was annexed to CSTI 

for their exclusive use on 28 May 1997. Copies of the licenses and agreements are presented in 

Appendix A. CSTI was observed to be operating a specialty hazardous materials training area 

to the east and adjacent to the former CAL FIRE FTA. A chain link fence was observed to separate 

the two parcels. CISTs use of this adjacent area is described in more detail in Section 3.6. 

3.6 California Men’s Colony Wastewater Treatment Plant

A WWTP is situated at the western end of Tehama Avenue, near Chorro Creek (Figure 3-1). The 

geographic coordinates of the approximate center of the facility are 35°19'26.98"N; 

120°45'7.77"W.

The WWTP, operated by CMC, was part of Camp SLO until about 1967, when ownership of this 

parcel was transferred from the CA Department of the Military to the California Department of 

Corrections via the California Office of Real Estate Services. The facility is used to treat 

wastewater from CMC, Cuesta College, El Chorro Regional Park, Camp SLO, and various county 

facilities (GeoSystem Consultants, 1996). 

No known storm drains were identified in areas of the facility where PFAS were released.

3.7 Former Paint Booth in Building 1341

There is one known paint booth that was constructed in Building 1341. The geographic 

coordinates are 35°19’11.5”N; 120°44’14.3”W(Figure 3-1). The paint booth was reported by the 

Camp SLO Environmental Manager to have never been used, as it did not pass San Luis Obispo

County health requirements. The booth was subsequently removed in approximately 2007, 

following an Environmental Programs (EPAS) inspection, and is therefore not considered a 

potential PFAS release location. 

3.8 Fuel Point

The Fuel Point is situated north of Chorro Creek and east of Dairy Creek. The geographic 

coordinates are approximately 35°19'46.0"N; 120°43'46.0"W. According to information provided 

by a Camp SLO environmental scientist, a foam applicator and a 5-gallon container of AFFF were 

observed. The former fuel point technician indicated that AFFF was to be on site in the event of a 

fueling facility fire. The history of use and times period of storage of the AFFF is unknown.

4. Emergency Response Areas

Camp SLO personnel identified one emergency response area during the PA. The emergency 

response area is shown on Figure 4-1. Interview records appear in Appendix B. A photograph 

of the area is included in Appendix C. 

4.1 1972 de Havilland Beaver Plane Crash

On 9 April 1972, a single engine de Havilland Beaver belonging to the US Army crashed at the 

southeastern end of the Camp SLO (O’Sullivan) Airfield runway and came to rest on the banks of 

Chorro Creek. The approximate geographic coordinates of where the plane crashed are 

35°19'27.71"N;20°44'24.36"W. 

The stretch of Chorro Creek in the area of the plane crash is heavily vegetated and has relatively 

steep stream banks. At the time of the PA site visit, water was flowing in the Creek. The Camp 

SLO airfield is currently used by the CA ARNG for helicopters. Waters in Chorro Creek flow east 

to west.

Interviewees did not recall whether AFFF were used to extinguish any fires.

5. Adjacent Sources

The USEPA collects occurrence data for potential contaminants that may be present in drinking 

water but does not have enforceable drinking water standards under its Unregulated Contaminant 

Monitoring program. For this PA, the 3rd Unregulated Contaminant Monitoring Rule (UCMR 3) 

data for water purveyors within a 10-mile radius of Camp SLO was searched for PFAS-specific 

data. Appendix A includes the UCMR3 2013 tabulated data set. 

According to the UCMR3 database search, the Atascadero Mutual Water Company had a 

detection of PFOA at one of their treatment buildings on 30 October 2013, the date of sample 

collection. The detection of PFOA was above the laboratory’s 0.02 nanogram per liter (ng/L) 

method reporting limit at a concentration of 0.028 ng/L. The exact location of where the water was 

sampled is not known. The southern-most developed portion of the city of Atascadero is located 

approximately 9.5 miles to the northwest and hydraulically upgradient of Camp SLO, the area in 

between which is comprised of mostly undeveloped mountain ranges. 

PCLF is located about 1 mile to the northwest of the main entrance to Camp SLO, north of and 

adjacent to Pennington Creek Road. The landfill is situated to the east of and adjacent to a 

tributary to Pennington Creek. The ownership of this property was transferred to CA State 

University, San Luis Obispo (CAL Poly) from the CA Department of the Military, sometime around 

1968. The PCLF has been referred to as the Cal Poly landfill. The landfill is adjacent to a part of 

Camp SLO which became El Chorro Regional Park. Little information is available regarding the 

type and amount of waste disposed in the PCLF other than that the landfill was filled using trenchand-cover methods. No information obtained indicates PFAS-related materials were disposed of 

in the landfill. 

No other off-site PFAS sources adjacent to the Camp SLO facility were identified during the PA 

through interviews or the EDR Report. Figure 5-1 depicts the location of the City of Atascadero 

and the PCLF.

6. Preliminary Conceptual Site Model

Based on the PA findings, six areas where PFAS were potentially released to the environment

were identified during the PA. The AOIs and preliminary CSMs for the AOIs are shown on Figure 

6-1 and Figure 6-2, respectively, and summarized below.

Two FTAs where PFAS were potentially released to the environment and consequently can be

considered source areas include the following: 

• AOI 1 - Former CAL FIRE FTA

• AOI 2 – Former META Yard Fire Training Area

Three non-FTAs where PFAS were potentially released to the environment include:

• AOI 3 – CAL FIRE Cuesta Camp Tenant

• AOI 4 – O’Sullivan Air Field Shed

• AOI 5 – de Havilland Beaver Crash site

• AOI 6 – Fuel Point

The following sections describe the CSM components and the specific preliminary CSMs

developed for each AOI. The CSM identifies the three components necessary for a potentially 

complete exposure pathway: (1) source, (2) pathway, (3) receptor. If any of these elements are 

missing, the pathway is considered incomplete. 

In general, the potential PFAS exposure pathways are ingestion and inhalation. Dermal contact 

is not considered to be a potential exposure pathway, as studies have shown very limited 

absorption of PFAS through the skin (National Ground Water Association [NGWA], 2018).

Receptors for Camp SLO include site workers, construction workers, farmers, residents, and 

trespassers. The preliminary CSMs for each AOI indicate which specific receptors could 

potentially be exposed to PFAS. 

6.1 AOI 1 Former CAL FIRE Training Area

AOI 1 is the former CAL FIRE FTA, now used by Phillips for a once-annual fire training session

(Figure 6-1). Potential PFAS releases to soil by CAL FIRE occurred at AOI 1 during fire training 

activities from 1995/1996 to 2005/2006. On a once-annual basis during these years, one 5-gallon 

container of 3% AFFF was reported to have been used to train fire fighters on how to apply foam. 

The foam was directed at various props and a concrete cinder-block structure. AFFF was expelled 

from equipment nozzles during the training and released to the ground surface, which was 

observed in aerial photographs and during the PA site visit to be gravel covered. 

PFAS are water soluble and can migrate readily from soil to groundwater or surface water via 

leaching and run-off. Because potential PFAS releases to surface and subsurface soil occurred, 

it is possible that PFAS migrated from the surface soil at AOI 1 to waters in Chorro Creek, which 

is located approximately 200 feet downslope and to the northwest of the area. In addition, 

precipitation infiltrating into the gravelly covered areas at AOI 1 may cause the migration of PFAS

from surface and subsurface soil to groundwater. 

Ground-disturbing activities to surface soil at AOI 1 and surface water and sediment in Chorro 

Creek could result in site and construction worker and trespasser exposure to potential PFAS 

contamination. Ground-disturbing activities to subsurface soil could result in construction worker 

exposure. Therefore, the exposure pathway for inhalation of soil particles and ingestion of soil is 

potentially complete for these receptors. 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

34

Camp SLO drinking water is supplied by waters piped to Camp SLO from the Whale Rock 

reservoir, which is situated approximately 11 miles west and hydraulically upgradient of the facility. 

Three water wells historically used for potable water are no longer used. As such, the exposure 

pathway of ingestion of groundwater at Camp SLO is incomplete. However, surface water in 

Chorro Creek may be potentially impacted by PFAS. Therefore, the exposure pathway for 

ingestion of surface water and sediment is potentially complete for site and construction workers, 

trespassers, and off-facility residents and farm or construction workers downstream of the facility.

Downgradient potable wells supply water to the coastal town of Los Osos, which is about 4 miles 

downgradient of Camp SLO. Conservatively, this could be a complete pathway for PFAS in 

groundwater.

6.2 AOI 2 Former META Yard Fire Training Area

AOI 2 is a parking lot area that was reportedly used for fire training (Figure 6-1). Potential PFAS 

releases to the east parking lot area of the META yard occurred as early as 1978 through 2005.

Because potential PFAS releases to surface soil at AOI 2 have occurred, PFAS may migrate from

surface soil at AOI 2 to surface water via run-off and to groundwater via leaching. Grounddisturbing activities to surface and subsurface soil could result in site and construction worker 

exposure. Therefore, the exposure pathway for inhalation of soil particles and ingestion of soil is 

potentially complete for these receptors.

Additionally, surface topography declines to the south of the eastern parking lot area towards a 

drainage ditch holding wetlands and to the southwest towards Poison Oak Creek. During large 

rainfall events, surface water and sediment may flow overland into the ditch, which is adjacent to 

the SALF, and be carried by Poison Oak Creek into Chorro Creek. Ground-disturbing activities in 

drainage ditches, at Poison Oak Creek, and at Chorro Creek could result in site and construction 

worker and trespasser exposure to potential PFAS contamination in surface water and sediment. 

Well No. 3 is situated downgradient of the FTA. The water well is no longer used as a potable 

water supply. As such, the exposure pathway of ingestion of groundwater at Camp SLO is 

incomplete. Surface water in Chorro Creek may be impacted by PFAS. Therefore, the exposure 

pathway for ingestion of surface water and sediment is complete for site and construction workers, 

trespassers, and off-facility residents and farm or construction workers downstream of the facility.

Downgradient potable wells supply water to the coastal town of Los Osos, which is about 4 miles 

downgradient of Camp SLO. Conservatively, this could be a complete pathway for PFAS in 

groundwater.

6.3 AOI 3 CAL FIRE Cuesta Camp Tenant

AOI 3 is located in the northeastern portion of Camp Roberts, at a fueling facility associated with 

Cuesta Camp, which is operated by CAL FIRE. The fueling facility is in the vicinity of Building 621

(Figure 6-2). Potential PFAS releases to concrete surfaces occurred in 2013 during the flushing 

out of hoses and a tank that contained AFFF. The precise location, amount, and type of AFFF 

released to the pavement and the condition of the pavement are not known. The area was not 

observed during the PA site visit. 

PFAS was reportedly released to a concrete surface and potentially migrated to the subsurface 

through cracks in the concrete or to areas off to the sides of concrete covered areas. Precipitation 

infiltrating AOI 3 may cause the migration of PFAS from surface and subsurface soil to 

groundwater. AOI 3 is upgradient of Chorro Creek, and the pathways and receptors are the same 

as described in Section 6.2. 
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

6.4 AOI 4 O’Sullivan Airfield Shed

AOI 4 is a shed at the O’Sullivan Airfield and was observed during the PA site visit to contain two 

Tri-Max crash carts that typically contain AFFF, three 5-gallon buckets of Chemguard 3% AFFF, 

and one 5-gallon bucket of FireAide 3% AFFF (Figure 6-1). The AFFF is stored on a concrete 

surface. Surface water and groundwater at and within the vicinity of the shed likely flows to the 

west/southwest, towards Chorro Creek.

Although none were reported, incidental spills of stored AFFF could migrate to the subsurface 

through cracks in the concrete or to areas off to the sides of concrete covered areas. Precipitation 

may cause the migration of PFAS from concrete surfaces and subsurface soil to groundwater. 

Surface waters may have also migrated to Chorro Creek, which is located approximately 500 feet 

to the south of the shed.

Ground-disturbing activities in unpaved areas downslope of the shed and surface water and 

sediment in Chorro Creek could result in site and construction worker and trespasser exposure 

to potential PFAS contamination. Ground-disturbing activities to subsurface soil could result in 

construction worker exposure. Therefore, the exposure pathway for inhalation of soil particles and 

ingestion of soil is potentially complete for these receptors. 

The exposure pathway of ingestion of groundwater at Camp SLO is incomplete; however, surface 

water in Chorro Creek may be potentially impacted by PFAS. Therefore, the exposure pathway 

for ingestion of surface water and sediment is complete for site and construction workers, 

trespassers, and off-facility residents and farm or construction workers downstream of the facility.

Downgradient potable wells supply water to the coastal town of Los Osos, which is about 4 miles 

downgradient of Camp SLO. Conservatively, this could be a complete pathway for PFAS in 

groundwater.

6.5 AOI 5 de Havilland Beaver Crash Site

In 1972, a de Havilland Beaver airplane belonging to the US Army crashed and came to rest in 

Chorro Creek. Interviewees did not recall whether AFFF were used to extinguish any fires. 

Surface water in Chorro Creek may be potentially impacted by PFAS. Therefore, the exposure 

pathway for ingestion of surface water and sediment is complete for site and construction workers, 

trespassers, and off-facility residents and farm or construction workers downstream of the facility.

6.6 AOI 6 Fuel Point

AOI 6 is located north of Chorro Creek and East of Dairy Creek, at a Fuel Point where a 5-gallon 

container of AFFF and an applicator were present during fueling operations. The fuel point is 

situated on a concrete surface. 

If AFFF were released, it could migrate through cracks in the concrete surface or off the concreate 

to uncovered areas. Precipitation may cause the migration of PFAS from the concrete surface 

and subsurface soil to groundwater. Surface waters may have also migrated towards Chorro 

Creek, which is located approximately 2,000 ft southwest of AOI 6.

Ground-disturbing activities to surface soil downslope of the Fuel Point and surface water and 

sediment at Chorros Creek could result in site and construction worker and trespasser exposure 

to potential PFAS contamination. Ground-disturbing activities to subsurface soil could result in 

construction worker exposure. Therefore, the exposure pathway for inhalation of soil particles and 

ingestion of soil is potentially complete for these receptors.
Final PFAS Preliminary Assessment Report

Camp SLO, San Luis Obispo County, California

36

Camp SLO drinking water is supplied upgradient of the facility. As such, the exposure pathway of 

ingestion of groundwater is incomplete. However, surface water at Chorro Creek may be 

potentially impacted by PFAS. Consequently, the exposure pathway for ingestion of surface water 

and sediment is potentially complete for site and construction workers, trespassers, and off-facility 

residents and farm or construction workers downstream of the facility. Downgradient potable wells 

supply water to the coastal town of Los Osos, which is about 4 miles downgradient of Camp SLO. 

Conservatively, this could be a complete pathway for PFAS in groundwater.

6.7 Secondary Migration of PFAS to Chorro Creek

Chorro Creek flows from east to west through the cantonment area of Camp SLO and is the 

primary surface water drainage feature (Figure 6-2). The Creek drains out of highlands northeast 

of the facility before entering Chorro reservoir, situated in the northeastern portion of the facility. 

The Creek then flows beneath Highway 1 and through the main portion of the Camp SLO 

cantonment area before flowing past the facility’s southwest property boundary. Chorro Creek and 

some of its tributaries are blue-line streams that usually flow year-round (CSLRCD, 2001). 

Downstream of Camp SLO, Chorro Creek flows to the Morro Bay Estuary at the Moro Bay State 

Marine Reserve, after which it flows into the Pacific Ocean. During wetter conditions, water may 

flow from Chorro Creek into the water table. If water is still flowing in Chorro Creek during drier 

periods, it is likely due to groundwater discharge.

Chorro Creek has several small tributary streams that flow through the facility. These streams 

include Dairy Creek, which originates just north of the property boundary, and Pennington Creek, 

which flows northeast to southwest and joins Chorro Creek just west of the CMC WWTP. A third, 

smaller tributary, Poison Oak Creek, is situated in the southwestern corner of Camp SLO. This 

tributary creek flows from the southeast to the northwest, in an area south of the SALF and CMC 

WWTP. Forested/shrub and emergent wetlands areas exist in relatively contiguous areas 

adjacent to Chorro Creek and its tributaries, within the various creeks’ stream banks. 

All six AOIs described above are known to have AFFF release or have the potential for a PFAS 

release to the environment and are within close proximity to Chorro Creek and its tributaries. The 

PFAS releases to soil and a concrete surface may have potentially migrated to Chorro Creek by 

means of surface water flow and infiltration. Therefore, site and construction workers, trespassers, 

and off-facility residents and farm or construction workers downstream of the facility could be 

exposed to potential PFAS in surface water and sediment.

Based on documented potential PFAS releases at these AOIs, there is potential for exposure to 

PFAS contamination in surface soil to all receptors via ingestion and inhalation, subsurface soil 

to site and construction workers via inhalation; and, surface water, sediment, and groundwater to 

construction workers, farm workers and downstream residents via ingestion. 

The areas listed in Table 7-2 and discussed in Section 2 through Section 5 were determined to 

have no suspected PFAS releases to the environment:

7.2 Uncertainties

A number of information sources were investigated during this PA to determine the potential for 

PFAS-containing materials to have been present, used, or released at the facility. Historically, 

documentation of PFAS use was not required because PFAS were considered benign. Therefore, 

records were not typically kept by the facility or available during the PA on the use of PFAS in 

training, firefighting, or other non-traditional activities, or on its disposition. 

The conclusions of this PA are predominantly based on the information provided during interviews 

with personnel who had direct knowledge of PFAS use at the facility. Sometimes the provided 

information was vague or conflicted with other sources. Gathered information has a degree of 

uncertainty due to the absence of written documentation, the limited number of personnel with 

direct knowledge due to staffing changes, the time passed since PFAS were first used (1969 to 

present), and a reliance on personal recollection. Inaccuracies may arise in potential PFAS 

release locations, dates of release, volume of releases, and the concentration of AFFF used. 

There is also a possibility the PA has missed a source of PFAS, as the science of how PFAS may 

enter the environment continually evolves.

In order to minimize the level of uncertainty, readily available data regarding the use and storage 

of PFAS were reviewed, retired and current personnel were interviewed, multiple persons were 

interviewed for the same potential source area, and potential source areas were visually 

inspected.

Table 7-3 summarizes the uncertainties associated with the PA:

information is available regarding any incidental spills of the 

stored AFFF containers.

AOI 5 de Havilland 

Beaver Crash Site

Interviewees did not recall whether AFFF was used to extinguish 

any fires that may have resulted from the crash.

AOI 6 Fuel Point Concentration of AFFF and its duration on site are unknown. 

7.3 Potential Future Actions

Based on the documented absence of the use or release of PFAS-containing materials at the

locations listed in Table 7-2, evidence does not indicate that current or former ARNG activities 

contributed PFAS contamination to soil, groundwater, surface water, or sediment at the facility or 

adjacent areas. These locations will not move forward in the CERCLA process.

Interviews and records indicate that current or former ARNG activities may have resulted in 

potential PFAS releases at the six AOIs identified during the PA (Table 7-1). Based on the 

preliminary CSMs developed for the AOIs, there is potential for receptors to be exposed to PFAS 

contamination in soil, groundwater, surface water, and sediment at these AOIs. Table 7-4

summarizes the rationale used to determine if the AOI should be considered for further 

investigation under the CERCLA process and undergo an SI. 

ARNG evaluates the need for an SI at Camp SLO based on the presence of PFAS releases, 

possible receptors, and the migration potential of PFAS contamination to receptors.

.

The Sutter Avenue Landfill is tocffi inlf{e southeast corner of Camp SLO (Figure 2). A review

of aerial photogr-aphs (Ge-q..System}i fltindicates that waste disposal began between 1969 and

1973 and continued untit ttrg,,,g$-1980's. Wastes reported to have been disposed included

commercial rubbish, .".up *o"od, scrap metal, weapon oil, brush and grass clippings, and some

WaStes in some parts of the landfill are thought be submerged below the water table during

periods of high ground water.

Previous Investigations

Several investigations have been conducted at the Sutter Avenue Landfill. The most recent and

comprehensive investigations were conducted by Geosystem (1995, 1995a,1995b). Ten

been conducted periodically from September 1990 until December 1993, and quarterly from

October 1994 to the present.

Detection Monitoring

In 23 CCR, $2550.1.a.(1), a,dffiotion monitoring program is required for ground water at a

landfill. A detection monitoring program was instituted at Sutter Avenue landfill in October

1994. Based on analytical results for the October 1994 monitoring event, and retesting in

Decernber 1994 andJanuary 1995,itwas concluded that a release had occurred. Several organic

constituents, including l, 4-dichlorobenzene, carbon tetrachloride and chloroform were

identified in down gradient wells.

Following detection of a release from the landfill, establishment of an evaluation monitoring

program, and subsequently a corrective action monitoring program, is required. However, 23

C:\OFFI CE\WPWI N\WPDOCS\CAM PSLO\RECOMM. DOC February 5, 't996

CCR $2550.1.c requires continuation of a detection monitoring program to provide detection of

subsequent releases. Detection monitoring should continue, in down gradient wells, for

monitoring parameters that have not been detected (or have not exceeded background).

Appropriate statistics should be conducted for monitoring parameters otler than those in the

Following retesting of the affected wells,,"Geosystem.submitted a revised report of waste

discharge (1995c). The closure and post closure plan for the landfill provides the required details

of corrective action for the landfi|l".,.In addition, Geosystem (i996) collected ground water

samples by HydroPunch@ and installed two additional wells to identiff the extent of the release.

The results-of.the investigation were not available at the time of this report, and the wells will not

program;.while the continuedidetection monitoring described above, and the corrective action

monitoring, described belowl,are long term programs.

Corrective Action Monitoring

Corrective action monitoring is required when the assessment of the extent of a release is

completed and the RWQCB approves the amended report of waste discharge for corrective

action (23 CCR $2550.1.a.(4)). The purpose of a corrective action monitoring program is to

demonstrate that the corrective measures are effective in reducing levels of constituents of

concern to below their respective concentration limits. With respect to those constituents that

showed significant evidence of a release, namely 1,4 dichlorobenzene, carbon tetrachloride and

chloroform, the Sutter Avenue Landfill should begin a corrective action monitoring progrirm

when the landfill cover is complete.

releases, the individual VOC's are probably the best indicator constituents, due to their absence

in background, and their,relativrely high mobility, as evidenced by the detection of VOC's in

down gradient wells. EPA method 8260 analysis should be conducted for volatile organic

constituents to provide concentrations of individual constituents and to maintain consistency

with the quarterly monitoring conducted to date. Dichlorodifluoromethane was detected in well

MW-1 in,October and December 1994, but has not been analyzed in subsequent monitoring.

Future monitoring events should report dichlorodifluoromethane by 8260 analysis.

Total dissolved solids, pH (field), electrical conductivity (field) and chloride should be retained

to provide evidence of a release of inorganic constituents, although statistical testing should not

Monitoring Frequency

Regulations call for either quarterly sampling of ground'water (23 5Cp $2550 .7.e.12.8.2) or

semi-annual sampling with four samples collected frq$mon monitoring point during each

sampling event (23 CCR $2550.7.e.12.B;1"). HoweV€i, it:is,,also stated that the sampling method

(including the samplingfrequency and the interval of time between successive samples) shall be

appropriate for the medium from which samples are taken ( CCR $2550.7.e.12.B). For ground

water at Sutter Avenue Landfill#arterly mbnitoringmay not be appropriate.

Ground waterhas been monitored on l2 occasions since September 1990, and quarterly since

October 1994. For most monit"riog d*eters, especially the VOC's that are most indicative of

a release, concentrationsvary over'dlh'mow range at individual wells (Figures 5 through 7). ln

addition, the times of highrandlow ground water levels, early spring and late fall, respectively,

have,been identified through.quarterly monitoring (Figure 8), and the difection of ground water

flow'is consistently to the north (Figures 3, 9 through 11). For these reasons, semi-annual

monitoring, or annual monitoring in some wells, may be appropriate unless a change in the

hydrogeologic regime occurs, such as with capping of the landfill.

.

Since a change in ground water recharge and concentrations of chemical constituents may occur

following capping of Sutter Avenue Landfill, quarterly monitoring should continue in down

gradient wells for a period of one year after closure. Future monitoring beyond one year may be

point of compliance, should be reduced to semi-annual monitoring if concentrations are stable or

decreasing, based on a statistical trend analysis. Wells MW-9 and MW-10, which are assumed to

concentration limits are reaohed in the wells down gradient from Sutter Avenue Landfill,

detection monitoring should&ntinue for a period of two years, at a semi:annual frequency for

time, and if no new evidence of a release is found, monitoring should be discontinued.

For each constituent of concern, a concentration limit must be defined. The concentration limit

may be either the background value of that constituent (23 CCR 2550.4.a.1) or a concentration

limit greater than background established pursuant to a corrective action program (23 CCR

exceeded background values should be established at the background value for that constituent.

For organic constituents detected in down gradient wells, the concentration limit should be

established as the California MCL for each constituent.

UNSATURATED ZONE MONITORING ii=' 1:+

Ground water at Sutter Avenue Landfill is less than ten feet below the ground surface in several

wells during periods of high gro water. [n fact, the base of waste is probably submerged

periodically. In light of this,,unsaturated rorre monitoring is not feasible, nor would it be

effective. , .,1,'..,,

r!d

SURFACE WATER MONITORING ==

'r,.tL '

After,closure of the landfill, waste will be isolated from surface runoff by a 60 mil HDPE cover.

Surface water could potentially be affected by discharge of ground water containing landfill

constituents. Assuming the extent of the release has been identified by wells MW-9 and MW-10,

however, affected ground water is approximately 1500 feet or more from an eventual discharge

point at,Chorro Creek. Continued ground water monitoring is the most effective means for

identifuing any potential future impacts to surface water.

Guidelines for the Preparation of Water Quality

Sampling and Analysis Plans (WQSAPS)

The Department is cunently in the process of developing a checklist for use in the

review (by Department staff) of WQSAPs. The items listed in that checklist are included in this

attachment to aid facilities in the preparation of their WQSAP.

The WQSAP is the document that completely describes the water quality monitoring

program for a regulated unit at a RCRA facility. lt must identify the regulated unit, describe

pertinent details about the construction of the unit and the historical use of the property, and

describe waste management activities at the unit. The WQSAP must describe the

hydrogeology of the area and contain specifications for the water quality monitoring systems

(ground water, surface water and unsaturated zone) in use at the facility. The WQSAP must

describe any contamination that has been identified and state whether the regulated unit will be

in detection, evaluation or conective action monitoring.

The WQSAP must tist the constituents of concern and monitoring parameters and

provide documentation to support the lists. The WQSAP must specify the sampling frequency

and the number and kinds of samples to be collected during each sampling event. The

WQSAP must provide information used to establish background values for all constituents of

concern and all monitoring parameters and must provide a detailed description of the statistical

methods to be used to evaluate analytical data.

The WQSAP must contain, or contain reference to, the Quality Assurance Project Plan

(OAPP). The QAPP must describe the data quality objectives (in terms of accuracy and

precision), acceptance criteria for analytical data and the format for reporting the results of the

Quality Assurance /Quality Control (OA/OC) program. (Note: Proposed detection limits must

be low enough to fulfill the data needs of the monitoring program.)

The WQSAP must contain detailed information describing the physical process of

sampling. This portion of the WQSAP is generally written as a stand alone document that is

appropriate for use by field personnel and is usually referred to as the sampling and analysis

plan (SAP)

A-1
Sampling and Analysis Plan Ghecklist

This sampling and analysis plan (SAP) checklist was developed to address the physical

process of obtaining field information, measurements, and water quality samples. The SAP

should be included in the WQSAP for each facility and should be written as an enforceable

document. Deviations from the procedures described in the cunent SAP for a facility are

subject to enforcement by the Department.

The SAP must be written to unambiguously describe exactly what steps will be taken to

ensure that representative samples are collected. The SAP must contain sufficient detail for a

sampler with limited experience to understand and follow and to ensure that sampling will be

conducted in the same manner by different samplers.

o The SAP must state that, before each sampling event (e.9. quarterly sampling)

each member of the field team must sign a document stating that he/she has

read and understands the cunent version of the SAP. A copy of this document

must be submitted to the Department with the report of analytical results.

. The SAP must describe equipment and procedures for the measurement of the

depth to water. The SAP must specifically state that water levels will be

measured in all wells and piezometers at least quarterly for the calculation of

ground water flow rate and direction, that all water levels will be measured in the

shortest possible time and that water levels in all wells will be measured before

any well is purged.

o The SAP must specify that water levels for the calculation of ground water flow

rate and direction will be measured during times of expected seasonal maximum

and minimum water levels. The SAP should specify when the seasonal

maximum and minimum water levels are expected (by month) and should

provide documentation (hydrographs) to support the conclusions.

. The SAP must state that the depth to water will be measured with reference to a

marked point that has been surveyed by a licensed surveyor. The water level

probe must be capable of obtaining reliable measurements to +/- 0.01 foot. The

SAP must specify the method for decontamination of the water level probe

between use at each well.

. The SAP must state the order in which wells will be visited for water level

monitoring, sampling, and maintenance and must contain the rationale for the

selected order in terms of minimizing the possibility of cross-contaminating the

wells and/or samples.

. The SAP must describe calibration procedures, frequency, and recordkeeping for

water level probes.

. The SAP must describe the procedures, frequency, and recordkeeping for

measuring the depth of the well casing.

A-2
The SAP must describe calibration procedures, frequency, and recordkeeping for

the well depth sounding instrument.

The SAP must describe or contain copies of exarnple field data sheets.

The SAP must state that well-head conditions (condition of well casing, well lock,

markings, standing water at surface) and any suggested maintenance will be

recorded in the field notes. The SAP must describe procedures for performing

necessary well maintenance in a timely manner.

The SAP must discuss the need to monitor for wellhead gases and immiscible

layers. lf necessary, the SAP must describe equipment and procedures for

testing wellhead gases and for testing the water surface for immiscible layers.

The SAP must describe the procedure for calculation of well casing volumes.

Where references are made to totalwell depth, it must be clear that the total well

depth is the welldepth as measured from the permanent mark on the well

casing. (Totalwell depth is also commonly recorded as depth below ground

surface.)

The SAP must specify the maximum purge rate for each well. Whenever

possible, purge rates should not exceed recharge rates. (Note: For wells

completed at the water table, maximum purge rates may be a function of the

water level in the well. The objective is to avoid purging a wellto dryness

whenever possible.)

The SAP must state that, unless wells are purged to dryness, a minimum of

three casing volumes will be removed during well purging.

Except for wells that are purged to dryness, the SAP must state that wells will be

purged until field parameters stabilize. DTSC believes that stability of field

parameters is the best indication that the water being sampled is representative

of the ground water in the aquifer. All measurements of field parameters are to

be recorded in the field log. The final, stable value for each field parameter must

be recorded and graphed through time for each well.

For wells purged to dryness, the SAP must describe procedures for removing as

much water as possible from the well, monitoring recharge, collecting samples

aS soon as the well has recharged sufficiently, and documenting the sampling

events. For wells that are bailed, the SAP must state that a well will only be

considered to have been purged until "dry" if less than 10o/o of the original

volume of water remains in the well after purging. (Note: The objective is to

minimize the amount of water that remains in the well after the well has been

purged "dry", because that water is expected to mix with the recharging water so

that the sample will be a combination of "stagnant" and "fresh" groundwater. lt is

important to optimize the percentage of "fresh" water.) The SAP must specify

the frequency for measuring recharge and the criteria for initiating sampling.

Sampling must proceed as soon as possible after the recharge criteria have

been satisfied. Samples for volatile organics must be collected no more than two

hours after purging.

A-3
a

For wells not purged to dryness, sampling should be conducted as soon as

possible after purging is complete. The SAP must specify, based on measured

recharge rates, the approximate time period after purging that sampling will

occur; or the SAP must describe the procedures for measuring and recording

water levels after purging and before sampling and must specify the criteria for

recharge.

The SAP must describe the equipment and procedures for measuring field

indicator parameters during purging. The SAP must specify the criteria for

determining that field parameters have stabilized before sampling (e.9., pH +/- .1

pH unit, temperature +l- l degree Celsius, conductivitY +l- 10o/o, turbidity +/-

10%) and must state the minimum purge volume between tests to determine if

field parameters have stabilized (e.9., one half casing volume). The SAP must

specifically state that turbidity will be measured with a turbidity meter. Visual

estimates are not sufficient.

The SAP must describe calibration procedures, frequency and recordkeeping for

all meters used during sampling. The SAP must state that the expiration dates

of standard solutions used for calibration will be recorded in the field log. Any

deviations noted during the day (e.9. meter drift) must also be recorded. lf meter

drift requires an adjustment to any final values for field parameters, the results

must be flagged in the data base.

The SAP must describe the procedures for recording flow rates and volumes of

water purged and for disposing of purged water. Field notes must include the

appearance of the purged water including its color and odor.

The SAP must describe the equipment and procedures for collecting samples.

Sampling equipment must be constructed of inert materials. Dedicated

equipment should be used whenever possible. lf equipment must be used at

more than one wellthe SAP must describe in detailthe procedures to

decontaminate the equipment and procedures for the collection of equipment

blanks.

The SAP must state that clean, powerless, surgical gloves (or another approved

type of glove) shall be worn by sampling personnel and shall be changed often.

The SAP must describe the sample containers (size and materials) for each type

of analysis.

The SAP must describe the labeling of the sample containers.

The SAP must describe the preservation techniques necessary for each type of

sample.

The SAP must describe the procedures for determining the amount of

preservative necessary to achieve the required chemical stability (e.9., amount

of acid necessary to ensure pH<2 for metals analysis).

a

A-4
The SAP must describe the procedures for checking and documenting the

results of preservation (e.9., checking whether metals samples have been

acidified to a pH of less than 2 and that temperatures are maintained at 4

degrees Celsius during shipping and storage). The SAP must state that

problems will be reported to the Department. (We have had some trouble with

laboratories documenting problems but not reporting them.)

The SAP must describe the equipment and procedures for taking each type of

sample. Sampling procedures must be designed to minimize disturbance of the

sample that could result in changes in water chemistry.

The SAP must present the rationale for deciding if samples for metals will be

filtered or not. The decision must include a consideration of the purpose of

sampling (i.e., detection monitoring, evaluation of a release or risk assessment).

lf filtering is required, the SAP must describe the equipment (including filter size)

and procedures for filtering samples. The use of in-line filters is preferred. lf inline filtration is not possible, filtering should be done as quickly as possible

(immediately) using positive pressure filtering equipment. The SAP must specify

the discard volume (the volume of groundwater that should be used to flush the

filter before sampling) for the type of filter to be used. lf manufacturer's

guidelines are not available, the SAP should specify that two times the capacity

of the filtering device will be passed through the filter and discarded before

samples are collected.

The SAP must state that bottles that have been prepared with preservatives will

not be overfilled.

The SAP must describe the equipment and procedures for storing samples for

transport.

The SAP must describe forms and procedures for sample transport and chain of

custody control. The SAP must specify the procedures to be followed to assure

that strict custody of samples is maintained during sample collection, storage

and transport (i.e., samples are not left unattended or samples are secured in

storage areas with limited access). Sample copies of chain-of-custody and

sample analysis request forms should be included

The SAP must describe equipment, procedures, and recordkeeping for

decontamination of all sampling equipment and protective gear. Equipment shall

not be used if visual signs, such as discoloration indicate that decontamination

was insufficient.

The SAP must describe the analytical method to be performed for each sample.

A-5
The SAP must state that, following each sampling event, each member of the

field team must sign a document that details any deviations ftom the SAP that

were ne@ssitated by field conditions (e.9, equipment failure, wells that could not

be sampled, etc.) and states that, with the exceptions noted above, allfield

measurements and samples were collected in accordance with the procedures

described in the SAP. A copy of this document must be submitted to the

Department with the report of analytical results.

A-5
Reporting Requirements

The WQSAP must describe in detailthe content and submittatdates for periodic reports

(including the submittal of quarterly determinations of groundwater flow rate and direction). The

plan should specify the name and address of the person at DTSC to whom reports and

notifications of significant finding must be addressed and should include the name, address and

phone number of the facility representative to contact for questions regarding the report.

Req u i rements for Quarterly Monitori n g Reports

Within 60 (or 90) days following each quarterly sampling event, the facility must submit a

quarterly monitoring report to the Department. The following requirements apply to each

quarterly monitoring report:

. The report must be presented in a professional report format with a table of contents

and numbered pages.

. Since the quarterly monitoring report must contain interpretations of hydrogeologic and

geochemical data, each report must be signed by a Geologist, registered in the state of

California who takes responsibility for the technical content of the report. This is

required by California state law - Business and Professions Code, Geologists and

Geophysicists Act. Reports must indicate the license number of the geologist.

. Each report must reference the current sampling and analysis plan (SAP) and state that,

with only the exceptions listed in the report, all sampling and analysis was conducted in

accordance with the current Plan.

o Each report must contain a detailed description of any deviations from the current SAP,

an explanation of the conditions that necessitated those deviations and a description of

any corrective measures being taken to avoid future deviations from the SAP.

. When appropriate, each report must describe recent changes to the monitoring program

that are allowed by the conditions of the current SAP. (For example, minor changes in

sampling or analytical equipment or protocol, addition of new or replacement wells to the

monitoring system, and the use of updated concentration limits.)

. Each report must contain a summary of the sampling event that identifies the type of

monitoring program for each regulated unit (detection, evaluation, and/or corrective

action) and describes significant findings.

. Each report must contain a narrative report summarizing and interpreting the results of

the monitoring event, including, but not limited to:

* Analysis of water level data and potentiometric maps, including a determination

of groundwater flow rate and direction in each hydrologic zone monitored at the

facility;

" A report on the results of quality assurance / quality control (OA/OC) sampling

and analysis. The report must state whether or not data quality objedtives of

A-7
Note:

accuracy, precision and completeness have been met. lf objectives were not

met (e.9., target detection limits were exceeded), this section must discuss

corrective measures (e.9., resampling) that are being taken by the facility and/or

the laboratory.

" Summary of the results of statistical analyses on water chemistry data;

" lnterpretation of soil moisture data; and

" Summary of the results of facility maintenance inspections of the monitored units

and their monitoring systems.

Each report must contain a current set of potentiometric maps for the facility.

Each report must include summary tables of current water level data, analytical data,

and the results of the statistical analysis.

Each report must contain supporting documentation related to the sampling event,

including, but not limited to: copies of field logs and activity sheets; depth to water data;

well head data; immiscible layer data; field parameter results; purge volume data; onscene observations; ch.ain-of custody forms; and laboratory data sheets (analytical

reports). lnternal laboratory calibration and QA/QC data need not be submitted to the

Department, but must be available at the facility or laboratory if needed.

Each report must contain an evaluation of the effectiveness of the leachate monitoring

and control facilities and of the run-off/run-on control facilities'

For active units, each report must describe the quantity and types of waste discharged

and the locations in the facility where waste has been placed since the submittal of the

last such report.

Each report must include a section that tracks outstanding issues and/or follow-up work

that needs to be performed (e.9., verification sampling of apparently significant evidence

of a release, repair or replacement of wells or equipment). Any item included in this

section must be addressed in every subsequent quarterly report untilthe outstanding

issue is resolved.

The documentation requirements for quarterly monitoring reports are not a

substitute for the notification requirements in section 66264.98 O(1) and

66264.98(l). As required by those sections, anytime the facility determines that

there is statistically significant evidence of a release from the regulated unit, the

facility must notify the Department by certified mailwithin seven days of making

that determination.
Requirements for Annual Monitoring Reports

By March 1 of each year (unless the facility permit states otherwise), the facility must

submit an annua! report that covers the activities of the previous year. The annual report may

be combined with the quarterly report for the fourth quarter provided it is submitted within g0

days of the fourth quarter sampling event and all items required for each report are included in

the annual report.

The following requirements apply to each annual monitoring report:

The report must be presented in a professional report format including a table of

contents and numbered pages.

Since the annual monitoring report must contain interpretations of hydrogeologic

and geochemical data, each report must be signed by a Geologist, registered in

the state of California who takes responsibility for the technical content of the

report. This is required by California state law - Business and Professions Code,

Geologists and Geophysicists Act. Reports must indicate the license number of

the geologist.

Each report must contain an executive summary of previous yeafs sampling

events that identifies the type of monitoring program for each regulated unit

(detection, evaluation, and/or corrective action) and describes significant findings.

Each report must contain a narrative report summarizing and interpreting the

results of the water quality monitoring program to date, including, but not limited

to:

* An analysis of water level data and potentiometric maps. Water level

. data, including hydrographs and potentiometric maps, must be evaluated

to determine if the water quality monitoring system is in compliance with

the requirements of Section 66264.97(b)(1) (i.e., the system satisfies the

data needs for the current monitoring program: detection, evaluation or

corrective action.) lf the system is not adequate, the report must specify

the steps that will be taken by the facility to achieve compliance with

those requirements.

* lnterpretation of the results of statistical analysis on water chemistry data;

and

* lnterpretation of soil moisture data.

Unless otherwise stated in the permit or sampling and analysis plan, each report

must contain comprehensive summary tables of all historical analytical data

related to water quality monitoring (groundwater, surface water, and soil-pore

liquid) at each regulated unit.

A-9
The following paragraphs address problems we have encountered in the review of many

WQSAPs. Please read them and consider whether these items should be included in your

document.

For detection monitoring, the WQSAP must specify the maximum amount of time that

will be needed after each monitoring episode to perform statistical analysis and make a

' determination of whether of not there is statistically significant evidence of a release from the

regulated units.

The WQSAP should describe well redevelopment and routine well maintenance. For

permitted facilities, it is wise to include a section on well decommissioning and replacement so

that those procedures can be implemented without a permit modification.

To evaluate the accuracy of the analytical data, the WQSAP should contain provisions

for initially, and periodically characterizing the major cations and anions and testing the results

by determining the charge balances. This could probably be most easily performed during the

initial sampling to establish background values for CoCs and during the periodic testing of CoCs

in downgradient wells.

For a detection monitoring program, the WQSAP must specifically state that DTSC will

be notified by certified mailwithin 7 days of determining statistically significant evidence of a

release for any monitoring parameter or constituent of concern at any monitoring point (Section

66264.980)). The WQSAP must describe the exact procedures for performing verification

sampling, specify the maximum amount of time before the results of the verification sampling

are reported to DTSC and state that, if the significant evidence of a release is confirmed, the

facility will comply with the requirements of Section 66264.98(k) Title 22 California Code of

Regulations (CCR) for responding to significant evidence of a release (e.9., immediately collect

samples for Appendix lX constituents and for all constituents of concern, etc.).

The monitoring plan should clearly state that actual laboratory values between the DL

and the practical quantitation limit (PQL) will be reported (and maintained in the data base) with

the numerical value determined by the laboratory and a flag to indicate that these values are

below the PQL. !n such €ses the value of the PQL must also be reported and maintained in

the data base. The practice of artificially censoring data that is reported below the calculated

PQL can lead to the use of less powerful statistical methods. lt is important to preserve the

actual uncensored values for all concentrations above the DL for possible use in future

statistical analysis.

1.0 INTRODUCTION

This report presents the findings of preliminary assessment PA for Camp San Luis

Obispo Camp SLO in San Luis Obispo County California Camp SLO is California

Army National Guard CA ARNG facility that occupies about 4100 acres of land to the

northwest of the city of San Luis Obispo At certain times in the past notably during World

War II and the Korean conflict Camp SW was operated by the U.S Army At the end of

World War II Camp SLO occupied almost 15000 acres of land The PA is the first step

in evaluating whether hazardous materials that may have been released at site pose

threat to human health and/or the environment The PA for Camp SLO was conducted by

Geosystem Consultants Inc Geosystem on behalf of the State Military Department

through contract with the State of California Department of General Services Division

of the State Architect DSA Specifically the PA was conducted pursuant to DSA

Agreement No 6952 Work Order No MAR 409 The remainder of this section presents

summaiy of the regulatory background the PA process in general and the application of

the PA process to Camp SW including the objectives and approach adopted by Geosystem

1.1 REGULATORY BACKGROUND

In 1980 the U.S Congress enacted the Comprehensive Environmental Response

Compensation and Liability Act CERCLA commonly known as the Superfund program

to address threats to human health and the environment posed by releases of hazardous

substances The CERCLA legislation required the U.S Environmental Protection Agency

EPA to establish criteria for determining priorities among the many sites at which releases

of hazardous substances had occurred or were threatened EPA subsequently developed the

Hazard Ranking System HRS to evaluate site priorities Those sites that posed

significant enough hazard were included on the National Priorities List NPL which

prioritized them for remedial action under the Superfund program The Superfund

Amendments and Reauthorization Act of 1986 SARA required EPA to modify the HRS

to better assess the relative degree of risk to human health and the environment posed by

sites EPA September 1991 SARA also required that the modified HRS take into

1-1

GESYSTEM

ConsultantsInc
account recreational use of surface waters contamination of the human food chain and

drinking water supplies and potential contamination of ambient air

In general terms the CERCLA process begins with site being discovered or identified

as possible hazardous waste site Discovered sites are entered into the Comprehensive

Environmental Response Compensation and Liability Information System CERCLIS

which is EPAs computerized inventory of potential hazardous sites The potential for the

release of hazardous substances from CERCLIS site is then evaluated during two-step

investigation the first step of which is PA The EPA has described the PA as limitedscope investigation based on reconnaissance of the site and surrounding area and

utilizing readily available information EPA September 1991 Sampling and chemical

analysis is generally not conducted during PA EPA goes on to say that the PA is

designed to distinguish between sites that pose little or no threat to human health and the

environment and sites that require further investigation

If further investigation is required site inspection SI the second step of the two-step

investigative process is initiated The SI typically involves the collection and chemical

analysis of samples of waste and environmental media such as soil ground water surface

water and air When the PA and the SI are complete the HRS is applied to derive site

score which determines either that further investigation is required or that the site should

receive no further remedial action planned NFRAP recommendation Note that

NFRAP recommendation means that no further action is required under the Superfund

program however states and/or other regulatory agencies may take action under their own

programs

if the sites FIRS score is sufficiently high it may be eligible for proposal to the NPL NPL

or proposed NPL sites must progress through the remainder of the Superfund process This

includes remedial investigation RI feasibility study FS Record of Decision ROD

which documents the selected remedy and the remedial design/remedial action RD/RA

1.2 OVERVIEW OF THE PA PROCESS

Regulations pertaining to PM are specified in the National Oil and Hazardous Substances

Pollution Contingency Plan NCP Suggested procedures for conducting PM are described

in EPAs September 1991 publication entitled Guidance for Performing Preliminary

Assessments under CERCLA In addition to site reconnaissance and the compilation and

evaluation of readily available information about the site and surrounding area the PA

focuses on collecting information about targets such as populations and resources that

might be threatened by release from the site

After gathering the necessary information the PA site evaluation phase addresses four

hazardous substance exposure routes or pathways These include three migration pathways

ground water surface water and air and one exposure pathway exposure to soil Each

pathway represents means by which hazardous substances may pose threat to human

health and/or the environment

The ground water pathway accounts for the migration of hazardous

substances to and within aquifers and the associated threat to drinking

water supplies

The surface water pathway accounts for the migration of hazardous

substances to surface water bodies and the associated threat to drinking

water supplies the human food chain sensitive environments and other

potential receptors

The air pathway accounts for the migration of hazardous gases vapors or

particulate matter in air and the associated threat to the human population

and other sensitive receptors

The soil exposure route accounts for the possible direct exposure of people

to contaminated materials via ingestion or dermal contact

For each pathway the PA must consider the likelihood of release the potential targets

and the characteristics of the wastes released

1.3 THE PA PROCESS FOR CAMP SLO

Camp SW was identified as potential hazardous waste site by the California Department

of Health Services DHS which now operates under the California EPA as the Department

of Toxic Substances Control DTSC during its Abandoned Site Project investigation in

1983 Specifically DHS determined that abandoned hazardous waste disposal sites probably

existed at Camp SLO However DHS was unable to obtain records pertaining to waste

types quantities or the locations where the wastes may have been disposed Camp SLO

was subsequently assigned CERCUS No CAD 980882773 Ecology and Environment May

10 1991

Applying the PA process to Camp SLO has proven to be perhaps more challenging than

for typical CERCLIS site Among the more challenging aspects were

The sheer size of Camp SW especially at the end of World War II when

it occupied almost 15000 acres and the diversity of the activities conducted

at Camp SLO at different times and at different locations In many

respects Camp SLO is more like small self-contained city than the

average CERCLIS site

Camp SLOs long and complicated history which dates back to 1928 and

which involves the piecemeal expansion of the facility through the end of

World War II and then the piecemeal contraction of the facility up to the

present day as excess land was disposed of

The very large number of buildings over 1000 and support facilities that

were constructed operated and then demolished and replaced with other

buildings and facilities Many hazardous and potentially hazardous

substances were probably used stored or otherwise handled in these

buildings and support facilities

The different ownership of different areas of the facility by the state

and/or the U.S government at different times and the different uses to

which different parts of the facility were put to by the owners and their

various tenants

The virtual absence of any written records pertaining to the storage use

and disposal of potentially hazardous materials within the current and

especially the historical boundaries of Camp SLO

1-4

GESYSTEM

Consultants Inc
The fact that hazardous materials have been used stored and possibly

released by several of the government agencies that now own or control

land that was formerly part of Camp SLO Any contamination resulting

from these more recent land uses may be superimposed on and

indistinguishable from contamination possibly attributable to prior military

use of the land

Some records pertaining to the recent storage use and disposal of potentially hazardous

materials at Camp SLO are available Also existing facilities where such materials are

handled were physically reconnoitered during the PA These records and reconnaissances

were the basis for evaluating potential threats from current activities at Camp SLO

However in evaluating the potential threats associated with activities in the past Geosystem

relied heavily on historical aerial photographs historical maps and plans of Camp SLO and

interviews with knowledgeable individuals The historical maps and plans were particularly

useful because they identified the function of the many buildings and facilities that have

been demolished/replaced adapted for different uses or leased to other users Knowing

the former use of building or area enabled Geosystem to extrapolate potential hazards

from buildings or areas that currently serve the same purpose By way of example

Camp SW used to feature five motor pools of which only one is present today However

operations were reportedly very similar if not identical at all of the motor pools

Therefore the potential threats associated with the existing motor pooi such as underground

storage tanks waste oil disposal etc probably also pertain to the former motor pools

1.3.1 Objectives

The overall objective of this PA is to ensure that Camp SLO is in compliance with the PA

requirements of CERCLA The specific objectives of the assessment are as follows

Identify and qualitatively characterize sites where the potential exists for

the release of CERCLA hazardous substances to the environment

Identify and qualitatively characterize sites where the potential exists for

the release of non-CERCLA hazardous substances to the environment

1-5

GFSYSTEM

Consultants Inc
Identify and characterize exposure and migration pathways and potential

receptors associated with possible release sites

Determine the need if any for further investigation and/or removal/

remedial responses for CERCLA and/or non-CERCLA hazardous

substances and make reconmiendations as appropriate

1.3.2 Technical Approach

On November 10 1994 Geosystem submitted proposal to DSA for the subject PA The

scope of the proposed PA was based primarily on EPAs September 1991 Guidance

Document for Performing Preliminary Assessments Under CERCLA and included the

following investigative activities

Visual reconnaissance of facilities within the current Camp SLO boundary

at which potentially hazardous materials may have been used stored

disposed or otherwise handled

Interviews with current and former employees of Camp SLO and tenants

at Camp SLO

Review of available records maintained by Camp SLO CA ARNG and

DSA

Review of records maintained by federal state and local regulatory

agencies

On February 1995 DTSC issued letter requesting that the scope of the PA be expanded

to address all areas within the former boundaries of Camp SLO Accordingly this PA

addresses all areas known to have been part of Camp SLO in the past in addition to the

area within the current boundary

The PA was initiated at kickoff meeting held at Camp SLO on February 24 1995 The

meeting was attended by Geosystem personnel and current CA ARNG and State Military

Department personnel familiar with operations at Camp SLO The field reconnaissance

work associated with the PA was conducted periodically from February 24 1995 to late June

1995 Many interviews with knowledgeable individuals were conducted over the same time

period In many instances field reconnaissance work was combined with field work related

to the ongoing investigations by Geosystem at solid waste disposal sites and underground

storage tank UST sites at Camp SLO The findings of these investigations which are also

being conducted through DSA on behalf of the State Military Department have been

extensively utilized in this PA

In addition to the reconnaissance work record reviews and interviews conducted at

Camp SW records and/or staff of the following agencies and organizations were reviewed

and/or interviewed

2.0 SITE DESCRIPTION AND OPERATIONAL HISTORY

This section describes Camp SLO in terms of its location and physiographic setting its

physical characteristics operational histoiy and status with regard to permits and violations

2.1 SITE LOCATION AND PHYSIOGRAPHICSETFING

Camp SLO straddles State Highway about miles northwest of the city of San Luis

Obispo California and about miles inland from Morro Bay and the Pacific Ocean The

location of Camp SW is shown in Figure The facility occupies approximately 4100 acres

and extends to the northeast from line between Cerro Romualdo and Chumash Peak

across the Chorro Creek Valley and up to Cuesta Ridge in the foothills of the Santa Lucia

Range The ground surface elevation at Camp SLO ranges from about 180 feet above mean

sea level MSL along the western boundaiy at Chorro Creek to over 2440 feet MSL in the

northeastern corner Almost all of Camp SW lies within the Chorro Creek watershed The

most developed and intensively utilized portion of Camp SLO referred to as the

cantonment troop housing area is located along Highway within the relatively narrow

Chorro Creek Valley The majority of the cantonment area and most of the buildings are

located on the south side of Highway The portion of the cantonment area north of

Highway is connected by an underpass In terms of area the bulk of Camp SLO lies to

the north of Highway in the foothills of the Santa Lucia Range This portion of

Camp SLO is essentially undeveloped other than for few unpaved roads Most of the area

is within one or more of the firing fans associated with the various firing ranges at

Camp SLO

In the past Camp SLO extended further north and west and occupied an area of almost

15000 acres To the north Camp SLO formerly extended over Cuesta Ridge and into

Kathleen Valley To the west it extended to San Luisito Creek Much of the area formerly

part of Camp SLO was also essentially undeveloped range land larger scale map of

Camp SW which shows the current and former boundaries and some of the physiographic

2.2 PHYSICAL CHARACTERISTICS

In very broad terms Camp SLO consists of the heavily developed cantonment area

number of training areas number of firing ranges and the associated firing fans and

related support facilities In the past the firing ranges/fans were substantially larger than

at present due to the use of heavier weapons In general terms the types of activities

supported by Camp SLO in the past were more or less the same as the present day but on

larger scale Since the end of World War II when it occupied nearly 15000 acres

Camp SLO has contracted as excess land was disposed of It is convenient to refer to the

The CMC is state prison facility located at the east end of Camp SLO north of

Highway CMC straddles Chorro Creek which divides the prison into the east facility

and west facility The east facility was constructed during the late 1950s The area was

formerly part of Camp SLO and featured troop hutments mess halls fuel facility and

other buildings The original Camp SLO buildings are visible in aerial photographs taken

in 1949 and 1956 An aerial photograph taken in 1959 shows that these buildings had been

demolished and the existing prison was under construction The CMC west facility occupies

the former Camp SW hospital Most of the original Camp SLO hospital buildings are still

present and are used by CMC

2.2.2 Range and Training Areas

Land outside of the cantonment area consists primarily of military training areas and firing

ranges The terrain is hilly with the northernmost portions of the ranges lying on the

southern face of Cuesta Ridge These areas are only accessible by four-wheel-drive vehicles

The existing firing ranges are discussed in more detail in Section 3.12 Much of the former

firing range and training areas at Camp SLO have been transferred to federal or state

agencies or returned to private landowners These areas are discussed briefly below

U.S Forest Service

Much of the northeasternmost portion of Camp SLO was borrowed from the U.S Forest

Service by the U.S Army when Camp SLO was expanded during the 1940s This land was

subsequently returned to the U.S Forest Service in 1966 Figure shows the former

Camp SLO land owned by the U.S Forest Service Most of the U.S Forest Service land

Peak The land is part of Los Padres National Forest and is largely undeveloped except for

number of communications transmitting stations located on the peaks It is noted that the

extreme northern portion of the U.S Forest Service land formerly part of Camp SW lies

within the Tassajara Creek watershed and the extreme eastern portion lies within the

Stenner Creek watershed The remainder lies within the Chorro Creek watershed

El Chorro Regional Park

El Chorro Regional Park lies to the north of the cantonment area across Highway

Figure The park is operated by the San Luis Obispo County Parks and Recreation

Administration This former Camp SLO land was used for military training and firing

ranges The northernmost portion of the park featured firing ranges and the southern

portion along Highway featured two hand grenade courts The terrain at El Chorro

Regional Park ranges from relatively gentle sloping hills along Highway to much steeper

slopes in the north and northeastern portion Most of the park is drained by Dairy Creek

which flows to the south through the center of the park and discharges into Chorro Creek

at Camp SLO

County Board of Education

The County Board of Education operates administrative and educational facilities on

parcel of property immediately west of El Chorro Regional Park along Pennington Creek

Figure number of hutments and associated buildings were constructed between

Pennington Creek Road and the creek itself sometime after 1956 Some of these structures

Privately Owned Land

The remaining former Camp SLO property is owned by private individuals or companies

specifically the Vollmers SPTC and Madonna Construction Company The locations of

privately owned parcels are shown in Figure Most of the land is reportedly used for

cattle grazing or agriculture So far as Geosystem has been able to ascertain none of these

three parcels was developed while part of Camp SLO The Volimer property was within

at least two firing fans however the SPTC and Madonna Construction Company parcels

were not within any known firing fans

2.2.3 Support Facilities

Support facilities associated with Camp SLO include reservoir and water filtration plant

water supply wells sewage treatment plant and solid waste disposal facilities The

reservoir and water filtration plant are still within the boundary of Camp SW although they

are now operated by CMC One of the three water supply wells is located at the County

Government Center Figure The other two are located in the current cantonment area

waste disposal facilities are discussed in Section 3.1

2.3 OPERATIONAL HISTORY

This section presents an overview of operations at Camp SLO in terms of site history site

operation and waste management practices

2.3.1 Site History

Camp SW was established in 1928 on 2000-acre tract of ranch land located west of the

city of San Luis Obispo The land was secured by Statc_cfcaliforniaona leasepurchase basis Then known as Fort Merriam after state Governor Camp SLO was the

first permanent base for the California National Guard Between 1928 and 1940 the size

of the base nearly tripled to total area of 5880 acres Geosystem has not been able to

reconstruct definitive summary of the parcels acquired their areas their former owners

and former land uses Several of the references reviewed in preparation of this report

include some of this information but in many cases the information is not consistent

between references Considering the information available however it seems likely that the

land acquired by Camp SLO was agricultural or range land

During the military buildup prior to the United States entering World War II the federal

government exercised its tive rights and assumed control of Camp SLO During the

war the U.S Army continued Camp SLYs development as an active U.S Army post The

base was ande4 and developed extensively between 1943 and 1946 during which time

the U.S Army used Camp SW as an infantry division training center summary of land

acquisitions by the U.S Army during this time is presented in Table At its peak Camp

SLO occupied 14959 acres and could accommodate more than 20000 troops The base

included artilleiy grenade and small arms firing ranges Improvements at the base included

2.3.3 Waste Management Practices

Currently nonhazardous solid wastes generated at Camp SLO are reportedly collected and

hauled off site for disposal at the Cold Canyon Class ifi landfill by private contractor

In the past nonhazardous solid waste disposal practices at Camp SLO included on-site trash

incineration and landfihling Camp SLO landfills are discussed in Section 3.1 and the trash

incinerator is discussed in Section 3.13

Hazardous wastes generated at Camp SLO are currently collected at two storage facilities

Organization Maintenance Shop 19 OMS-19 and the United States Property and Fiscal

Office USPFO The locations of these facilities are shown in Figure The wastes

collected at these facilities are periodically hauled off site for recycling and/or disposal by

private contractor under statewide contract The USPFO reportedly only disposes of

hazardous wastes generated at or returned to the USPFO facility Hazardous wastes

generated elsewhere at Camp SLO are taken to OMS-19 OMS-19 and USPFO are

discussed in greater detail in Sections 3.4 and 3.6 respectively Little information is

available regarding hazardous waste handling and disposal practices during the U.S Army

operation of Camp SLO

number of tenants at Camp SLO generate their own hazardous waste streams Each of

these tenants reportedly is responsible for its own hazardous waste disposal Wastes from

non-military tenants at Camp SLO are not accepted at OMS-19 or USPFO brief

description of hazardous materials and waste handled by each tenant is presented below

2.5 INSPECTIONS AND NOTICES OF VIOLATION

number of environmental inspections have been conducted at Camp SLO by various

federal state local and military agencies brief description of each of these inspections

is presented below

January 30 1985 EPA conducted polychiorinated biphenyls PCBs

inspection at Camp SLO The inspection resulted in notice of

noncompliance issued on January 1986 Section 3.10

May 1986 San Luis Obispo County Air Pollution Control District

APCD conducted an inspection of vapor recovery equipment on the

active USTs at Camp SLO Notice of Violation NOV 0325 was

issued on May 1986 The NOV required corrective action to repair or

replace defective gaskets and fill caps on several active gasoline USTs No

follow-up information was available to verify whether the required

corrective actions were taken

July 20 1987 San Luis Obispo County Health Agency inspected the

hutment heating oil systems at Camp SLO in response to surface spill

that occurred on July 17 1987 Two NOVs were subsequently issued

Section 3.3

May 11 and 16 1989 APCD inspected vapor recovery equipment on the

active USTs at Camp SLO NOVs 0941 through 0944 were issued

requiring repair of defective fill pipe equipment November 20 1989

letter from APCD indicated that Camp SLO had paid fine in the

amount of $150 and was released from any and all claims for civil or

criminal penalties arising from these NOVs However no follow-up

information was available to verify whether the required corrective actions

were in fact implemented

January 30 1990 EPA conducted PCB compliance inspection at

Camp SLO letter issued by EPA on March 19 1990 indicated that no

violations of federal PCB regulations were identified during the inspection

Section 3.10

January 1991 DTSC conducted waste generator inspection at Camp

SLO in response to complaint that CA ARNG should inspect and

regulate all tenants at Camp SLO in regard to hazardous waste

management DTSCs inspection report issued on January 29 1991

identified several waste-handling violations The violations reportedly

involved improperly labeled containers exceeding the 90-day holding time

and not having site-specific contingency plan for USPFO

2-13

GESYSTEM

ConsultantsInc
April 12 1994 CA ARNG Environmental Office conducted biennial

inspection of OMS-19 The inspection report issued on April 20 1994a

noted several deficiencies related to record keeping container labeling and

general housekeeping The report also recommended that the electronic

tank level monitoring system be calibrated and that damaged diesel fuel

tank fill pedestal be repaired There was no mention of unauthorized spills

or releases of hazardous substances in the report

April 13 1994 CA ARNG Environmental Office conducted biennial

inspection of USPFO The inspection report issued on April 20 1994b

indicated deficiencies similar to those reported in the OMS-19 inspection

report above In addition the report indicated that hazardous solid

waste containers such as paint cans were observed in the facility dumpster

April 12- 15 1994 CA ARNG Environmental Office conducted basewide biennial inspection of Camp SLO The inspection report issued

April 26 1990 identified several deficiencies Most of the deficiencies

identified were related to administrative or record-keeping procedures

The report noted that Camp SLO did not have current permit from

APCD to operate the paint spray booth located in Building 1341 in the

engineering yard

number of other NOVs have been issued regarding operations at Camp SLO NOV

was issued by the RWQCB on December 1994 related to Camp SLOs failure to obtain

storm water discharge permit for industrial areas on the base CA ARNG reportedly is

in the process of obtaining storm water discharge permit for Camp SLO It is Geosystems

understanding that NOV was issued by RWQCB regarding the grading of the interim

cover over the Sutter Avenue landfill Specifically the RWQCB has requested remedial

grading to prevent surface water ponding over the landfill The NOV was apparently

prompted by CA ARNGs failure to regrade the landfill cover

3.0 AREAS OF POTENTIAL ENVIRONMENTAL CONCERN

This section describes areas within the current and historical boundaries of Camp SW that

are considered to be of potential environmental concern Areas of potential concern include

locations where hazardous materials or wastes are known or suspected to have been used

stored or disposed at some time during Camp SLOs operational history

3.1 SOLID WASTE DISPOSAL SITES

There are four confirmed solid waste disposal facilities located within the former Camp SLO

boundary the Sutter Avenue Story Park Kansas Avenue and Pennington Creek landfills

The Sutter Avenue and Story Park landfills are located within the current Camp SW

boundary The Kansas Avenue landfill is located on property currently owned by the

County The Pennington Creek landfill is located on land currently owned by Cal Poly The

locations of the four confirmed landfills are shown in Figure Under separate contract

with DSA Geosystem recently prepared final closure plan for the Sutter Avenue landfill

and conducted subsurface investigations at each of the other three Soil ground water and

air quality data collected during Geosystems investigations at the four confirmed landfills

are included in Appendix and form the basis for the following summaries

In addition to the four confirmed landfills at Camp SW there are two locations where solid

wastes may have been handled One of these is located behind to the south of the former

laundry building Building 1200 which is on property now owned by the County The

second is reported to have been near Building 1649 near the western end of the cantonment

area on land still part of Camp SLO The evidence for these suspected solid waste sites

such as it is is presented in Section 3.1.5 Note that because of the inconclusive nature of

the evidence Geosystem has refrained from using the term landfill to describe these two

suspected solid waste sites Their approximate locations are shown in Figure

3.1.1 Sutter Avenue Landfill

The Sutter Avenue landfill is located in the southeast corner of Camp SLO Figure in

flat low-lying area in the Poison Oak Creek valley between Cerro Romualdo peak and

Conner peak The landfill is bounded by Poison Oak Creek to the southwest Sutter Avenue

and former Caltrans facility to the north and privately owned range land to the south

The southern boundary of the landfill is also part of the Camp SW boundary

topographic map of the Sutter Avenue landfill is presented in Figure

Records pertaining to the Sutter Avenue landfill are few however review of aerial

photographs indicates that waste disposal operations began sometime between June 29 1969

and October 24 1973 shortly after Camp SLO returned to State control CA ARNG

submitted Report of Waste Discharge for the landfill on November 12 1976 subsequent

to which the RWQCB issued waste discharge requirements WDRs in Order No 77-21

which was adopted on February 11 1977 RWQCB May 12 1989

Little is known about the types of wastes disposed of in the landfill prior to 1982 From

1982 to 1985 the wastes are reported to have been primarily commercial rubbish Other

wastes disposed of at the landfill included scrap wood scrap metal weapon oil brush and

grass clippings and some food waste Ecology and Environment Inc May 10 1991 The

wastes were disposed of within the landfill using the trench-and-cover method According

to the U.S Army Environmental Hygiene Agency USAEHA the trenches were reportedly

about 200 to 300 feet long feet wide and feet deep USAEHA July 1986

Approximately twice year open burns were conducted to reduce the volume of

agricultural wastes prior to burial USAEHA December 20 1989 It is noted that ground

water was encountered in some of the waste disposal trenches Specifically landfill

operating personnel reported that occasionally trench dug in the afternoon would be half

filled with water by the next morning USAEHA July 1986 This observation suggests

that disposed waste materials may be in contact with the ground water beneath the site

particularly during seasonally high water table conditions

3-2

GBYSTEM

Consultants Inc
Disposal of municipal-type waste materials in the landfill reportedly stopped in 1985 The

majority of the waste materials generated at Camp SLO since 1985 have been disposed of

off site although demolition debris was disposed of in the subject landfill after 1985 Some

of the demolition debris was reportedly ignited as part of fire fighter training program for

the staff of the CDF Also the USAEHA refers to 1987 county inspection report that

refers to mound of dirt and agricultural/wood wastes on the west side of the fill area

awaiting final burial

number of soil and ground water investigations have been performed at the Sutter

Avenue landfill since 1986 To date total of ten ground water monitoring wells

Wells MW-i through MW-1O have been installed around the landfill summary of the

ground water analytical data from these wells is included in Appendix to this report The

locations of the monitoring wells are shown in Figure Ground water contours generated

from ground water level measurements recorded in February 1996 are included in

Appendix The contours indicate that ground water beneath the Sutter Avenue landfill

flows to the north-northeast before swinging around to the north-northwest as the axis of

the Chorro Creek valley is approached The February 1996 contours are considered typical

for the Sutter Avenue landfill

As shown in Appendix Tables B-i and B-2 ground water beneath and immediately

downgradient of the Sutter Avenue landfill has been impacted by certain VOCs

and CA ARNG plan to close the Sutter Avenue landfill in the sunmier of 1996 Geosystem

anticipates that construction of an engineered final cover over the waste disposal area will

3.1.2 Story Park Landfill

The Story Park landfill is located about 600 feet north of Highway between the

main cantonment area of Camp SLO and the CMC The location of the Story Park landfill

is shown in Figure and larger scale topographic map is presented in Figure As shown

in Figure the landfill occupies relatively flat-lying triangular clearing surrounded by

trees and defined on the north and south sides by surface water courses and to the east by

small bedrock outcrop The ground surface in the clearing slopes gently from an elevation

of about 339 feet MSL in the southeast corner to about 334 feet MSL in the northwest

corner The area of the clearing potentially useable for waste disposal is about 1.82 acres

although as discussed below the area actually used for landfilling may be significantly

smaller Geosystem August 25 1995

The water courses that bound the landfill are Chorro Creek to the south and small

unnamed tributary to Chorro Creek to the north The tributary shown as drainage ditch

on several old drawings of Camp SLO originates in the hills to the west of Chorro

Reservoir In the vicinity of the landfill bedrock is exposed in the beds of both water

courses although the bedrock is partially obscured by large boulders The beds of the

stream-cut channels are between 10 and 15 feet lower than the surface of the clearing in

which the landfill is located Geosystem August 25 1995

The USAEHA has stated July 1986 that there are no operational records available for

the Story Park landfill and that the former operator has passed away USAEHA goes on

to note that information pertaining to the types of waste disposed of in the Story Park

landfill is not available Most of the following information has been gleaned and/or

inferred from historical aerial photographs historical plans of Camp SLO and waste

disposal procedures elsewhere at Camp SLO

3-5

GEEYSTEM

Consultants Inc
The earliest indication of any activity at the Story Park landfill site is an aerial photograph

taken on April 1949 which shows surface feature in the southeast corner of the landfill

area Plans of Camp SLO dated November 17 1952 identify this feature as an Imhoff tank

designated as Tank T-608 The approximate location of the former Imhoff tank is shown

in Figure Inihoff tanks are essentially prefabricated self-contained sewage treatment

systems that are analogous to aboveground septic tanks Geosystem has not been able to

locate any plans or aerial photographs older than April 1949 so it is not known when the

Imhoff tank was situated in the landfill area Subsequent aerial photographs show that the

tank was present until at least September 1956 The Imhoff tank is not present in an aerial

photograph taken in May 1965 although disturbed soil at the former tank location suggests

that the tank may have been recently removed

The presence of the Imhoff tank indicates that sewage may have been at least partially

treated at the Story Park landfill site while the U.S Army was in control of Camp SLO

The fact that the tank was assigned tank number suggests that it was operated rather

than merely stored at the landfill site Assuming the Imhoff tank was operated the absence

of support or auxiliaiy equipment in the aerial photographs suggests that the aqueous wastes

may have been discharged directly to Chorro Creek and that the digested solids may have

been applied to the ground surface and/or discharged to Chorro Creek It is not clear how

the waste stream arrived at the Imhoff tank The waste could have been trucked to the site

or perhaps more likely gravity flowed from latrines associated with the buildings to the

north

The only other indication of waste disposal activities at the Story Park landfill site is an

aerial photograph taken on February 13 1969 This photograph clearly shows smgle

trench excavated along the southern boundary of the clearing approximately parallel to

Chorro Creek The approximate location of this trench is shown The trench

is not visible in the preceding aerial photograph taken on May 1965 and appears to have

been backfilled by the lime the nxt available photograph was taken on June 29 1969

None of the subsequent photographs taken in November 1972 October 1973

3-6

GE1YSTEM

Consultants Inc
September 1978 and August 1987 show any indications of additional waste disposal activities

at Stoiy Park Currently the clearing features grass ground covering and is equipped with

several metal barbeque stands USAEHA has indicated December 20 1989 that the site

has been used as bivouac and training area in the past

Given the admittedly limited data available one possible scenario is that the single trench

visible in the February 17 1969 aerial photograph was excavated by the CA ARNG to

dispose of the solid residues resulting from years of sewage treatment at the site by the

U.S Army Under this scenario digested sludge from the Imlioff tank would have been

disposed of on the ground surface at the landfill site When the Imhoff tank was removed

between May 1965 and February 1969 it is likely that some type of cleanup would have

been required to restore the site for alternate uses The possibility that other waste

materials were also disposed of in the trench however cannot be ruled out

It is noted that the main Camp SLO waste water treatment system was reportedly

constructed by the U.S Army in the 1940s in the extreme southwest corner of Camp SLO

south of Highway It appears that the Imhoff tank may have been used to treat waste

generated in areas not served by the sewer system that reports to the main treatment system

Geosystem performed preliminary investigation at the Story Park landfill in late 1994/

early 1995 The investigation involved collecting and analyzing soil samples from three

borings and converting one of these borings into hydraulically downgradient ground water

monitoring well Well MW-i Ground water was encountered beneath the landfill at

depth of approximately 27 feet in Well MW-i Soil and ground water data from the Story

Park landfill are summarized in Appendix Tables B-4 B-5 and B-6 As shown in

Appendix there is no evidence that soil or ground water beneath the Story Park landfill

have been impacted by waste disposal operations Geosystem August 25 1995

of Highway Figure topographic map of the Kansas Avenue landfill is presented in

Figure As shown in Figure the landfill is bounded on the north by County Sheriff

facility on the east by chainlink fence and agricultural land on the south by the slope

flanking Cerro Romualdo and on the west by vacant field chainlink fence bisects the

landfill in the east-west direction The portion of the landfill south of the fence has been

cultivated for thy farming i.e unirrigated hay for cattle fodder County animal shelter

has been constructed directly over portion of the landfill on the north side of the fence

Figure In addition part of Oklahoma Avenue and the southernmost part of the County

Sheriff facility are believed to overlie disposed waste material

Little informationis available regarding the volume or type of wastes disposed at the Kansas

Avenue landfill Historical aerial photographs reviewed by Geosystem indicate that Kansas

Avenue is the oldest of the four landfills at Camp SLO The landfill was reportedly

operated from 1941 until approximately 1956 Ecology and Environment May 10 1991

Aerial photographs indicate that the landfill was in use by April 1949 and was still active

in 1956 By November 1959 however the landfill had become inactive During World War

II the Army reportedly monitored the wastes disposed at the Kansas Avenue landfill This

strict monitoring is believed to have been part of an aggressive recycling program

implemented by the Army to support the war effort Scrap metal was salvaged and oil

paint and solvent containers were not disposed in the landfill Monitoring was reportedly

not as strict after the war and some paint and oil/grease containers and dry cell batteries

were reportedly disposed in the landfill Ecology and Environment May 10 1991 The

animal shelter appears to have been constructed between May 1975 and 1977

Investigations have been conducted at the Kansas Avenue Landfill by Reidel Environmental

Services Inc Reidel of Torrance California and by Geosystem Also geotechnical

investigation for the construction of the County animal shelter was conducted in 1975

In November 1991 Reidel installed two 2-inch diameter ground water monitoring wells

Wells MW-i and MW-2 and four suction lysimeters Lysimeters IA through L-7 around

the Kansas Avenue landfill The locations of Well MW-i and the lysimeters are shown in

Figure However Well MW-2 was installed too far downgradient to be shown in Figure

and for all intents and purposes is irrelevant in evaluating the possible impact of the

Kansas Avenue landfill on the subsurface environment Ground water was encountered at

39 feet below grade in Well MW-i and at 8.5 feet below grade in Well MW-2 Soil samples

for chemical analyses were collected from the well borings but not from the lysimeter

borings Ground water and pore water samples were collected from the monitoring wells

and the lysimeters respectively In addition Reidel collected and analyzed ground water

sample from Camp SLO Well No and surface water sample from Chorro Creek

downstream of the landfill Geosystem installed two additional monitoring wells

Wells MW-3 and MW-4 and one soil boring Boring B-i in October 1994 Ground water

was encountered in Wells MW-3 and MW-4 at depths of 28 and 23 feet below grade

respectively However water level measurements taken in February 1995 indicated that

ground water levels in these wells had risen to near ground surface Similar variations in

depth have been observed in Camp SLO Well No Geosystem collected soil samples for

chemical analysis from Wells MW-3 and MW-4 and from Boring B-i Ground water

samples were collected from Wells MW-3 and MW-4 on October 26 1994 and from

Wells MW-i MW-2 and Camp SLO Well No on January 31 and February 1995

soil pore water sample was also collected from Lysimeter L-7 on January 31 1995

No VOCs or other organic compounds were detected in any of the soil samples collected

by Reidel or Geosystem Some elevated metals concentrations notably chromium and

nickel were detected in certain samples However the concentrations were similar to those

measured elsewhere at Camp SLO and are believed to reflect naturally occurring

concentrations in native soils Toluene was detected in Wells MW-3 and MW-4 at very low

concentrations 0.9 and 1.3 pg/e respectively No other compounds were detected in any

of the ground water samples Camp SLO Well No has been sampled on number of

occasions by Reidel Geosystem and the San Luis Obispo County Engineering Department

No VOCs or other constituents related to past landfilling activities have been detected in

this well Total recoverable petroleum hydrocarbons TRPH and Arochlor-1254 PCB

compound were detected in soil pore water sample collected from Lysimeter L-6 in

December 1991 by Reidel Detected concentrations were mgft and 1.8 respectively

No other organic compounds were detected in the pore water samples collected at the

landifil Reidel April 1993 Lysimeter L-6 was never resampled for TRPH or PCBs and

is believed to have been destroyed Geosystem sampled Lysimeter L-7 on January 1995

No organic constituents were detected except bis 2-ethyihexyl phthalate which is believed

to be sampling artifact at concentration of 75 JLgft Eleven soil gas samples were

collected by Geosystem at the Kansas Avenue landfill on February 1995 The samples

were analyzed for fixed gases which include methane nitrogen oxygen carbon dioxide and

carbon monoxide Methane and carbon monoxide were not detected in any of the samples

above the laboratory detection limits Geosystem October 1995

Except for low concentrations of toluene in ground water samples from Wells MW-3

and MW-4 it does not appear that the Kansas Avenue landfill has adversely impacted the

subsurface environment It is noted that Wells MW-3 and MW-4 have only been sampled

once The detected toluene concentrations are approximately two orders of magnitude

lower than the state action level of 100 pg/L Analytical data gathered during investigations

at the Kansas Avenue landfill are summarized in Appendix Tables B-7 B-8 and B-9

Ground water contours based on water levels measured on February 24 1995 are included

in Appendix

3.1.4 Pennington Creek Landfill

The Pennington Creek landfill is located about 1.2 miles northwest of the main entrance to

Camp SLO Figure and about 2000 feet north-northeast of Highway The topography

of the landfill area is shown in Figure The landfill is bounded on the northwest by

small tributary to Pennington Creek on the southeast by Pennington creek Road and on

the east by undeveloped rangeland The land around the Pennington Creek landfill was

3-10

GESYSTEM

Consultants Inc
originally part of Camp SLO but was acquired by Cal Poly in 1968 In the past the

Pennington Creek landfill was often called the Cal Poly landfill

Little information is available regarding the volume or type of wastes disposed of at the

Pennington Creek landfill Historical aerial photographs obtained by Geosystem show that

the site was inactive at least through September 1956 The next available photograph of the

Pens reek landfill was taken in May 1965 This photograph shows an open trench

indicating that the site was active at the time Subsequent photographs indicate that the

landfill has been inactive since at least October 1973 trenching investigation performed

by CAARNG rported1y indicated that the waste material was limited to thin 12- to

18-inch layer overlain by approximately 12 to 18 inches of soil The types of waste

observed reportedly included bottles cans other domestic garbage and discarded military

gas masks So far Geosystem is aware however the trenching investigation was not

documented inawritten report

An investigation was conducted at the Pennington Creek landfill by Reidel Environmental

Services Inc Reidel in November 1991 Specifically Reidel installed three suction

lysimeters Lysimeters L-1 L-2 and L-3 around the perimeter of the landfill Ground

water was encountered in one of the lysimeter borings at depth of about feet below

grade Several phthalate compounds were detected in soil samples collected from the

lysimeter borings However similar concentrations of these compounds were also detected

in background soil samples Metals concentrations detected in soil samples from the landfill

were similar to or lower than background samples Two surface water samples collected

from the adjacent creek did not contain detectable concentrations of organic constituents

Surface water and lysimeter samples did not contain significant metals concentrations

Reidel April 1993

Geosystem conducted preliminary investigation at the Pennington Creek landfill between

October 1994 and February 1995 The investigation involved drilling and soil sampling from

two borings conversion of one boring into monitoring well Well MW-i ground water

monitoring and soil gas monitoring In addition Lysimeter L-1 was sampled Organic

constituents including phthalates were below laboratory detection limits in all of the soil

samples analyzed as well as in the ground water sample from Well MW-i and the pore

water sample from Lysimeter L-1 No elevated metals concentrations were observed in soil

or ground water samples Geosystem August 21 1995 Geosystem also collected total

of five soil gas samples plus one background sample at the Pemiington Creek landfill The

soil gas samples were collected through temporary probes at depth of about feet below

grade The samples were analyzed for fixed gases including methane However methane

was not detected in any of the samples analyzed Geosystem August 21 1995

The findings of the Reidel and Geosystem investigations at the Pennington Creek landfill

indicate that waste disposal activities at the site have not adversely impacted soil ground

water or surface water quality Analytical data gathered during investigations at the

Pennington Creek landfill are summarized in Appendix Tables B-10 B-li and B-12

3.1.5 Other Potential Solid Waste Handling Areas

As noted in Section 3.1 there is some evidence albeit inconclusive that solid waste

materials were handled at two other locations within the historical boundaries of

Camp SLO The evidence such as it is is presented below and Geosystem again cautions

against using the term landfill to describe either of these two sites at this time

Mr John Scholtes of SLOCHA suspects potential waste handling area located directly

south of the former laundry Building 1200 on property now owned by the County More

specifically the area is located 600 feet south of Kansas Avenue and about 1400 feet west

of the Kansas Avenue landfill The approximate location is shown in Figure The

suspected disposal area is separated from the laundry building by wooded area along

small creek and is encircled by dirt or gravel road An undated low-level oblique aerial

photograph provided by Mr Scholtes shows what appears to be debris piles in this area

military truck is visible in the aerial photograph backed up to the debris piles Cars visible

in the photograph suggest that the picture was taken sometime during the 1940s No open

3-12

GEYSTEM

Consultants Inc
pits or trenches are evident in the photograph It is possible that the suspected debris piles

may have consisted of scrap metal and other recyclable items that were not disposed of in

the on-site landfills Alternately the piles may have been wastes from which recyclables had

yet to be separated prior to disposal

The second potential waste handling area is located in the westernmost end of the

cantonment area More specifically the area is believed to be located in the cleared area

bounded by Sutter Mono Tehama and Merced Avenues Some concrete debris is currently

visible at the ground surface in this area According to CMC employee desks books and

other office supplies were buried in this area in the early 1980s These items were

reportedly removed from buildings vacated by CA ARNG that were to be occupied by CCC

3.2 UNDERGROUND STORAGE TANKS

Many dozens of USTs were operated over the years at Camp SLO The majority of these

tanks were reportedly installed by the U.S Army during the 1940s Most if not all were

used to store petroleum products including heating oil diesel fuel and gasoline referred

to as MOGAS by the militaiy Nearly all of the USTs at Camp SLO have been removed

or abandoned in place The few remaining tanks are used to store diesel and gasoline to

fuel military and other State-owned vehicles Brief summaries of the active and abandoned

USTs at Camp SLO are presented in Sections 3.2.1 and 3.2.2 respectively

3.2.1 Active Underground Storage Tanks

Currently there are five active USTs located within the Camp SLO boundary Two of these

USTs located near Building 962 are operated by CDF and store gasoline and diesel fuel

Another two USTs are located north of Building 1328 across Sutter Avenue These USTs

are operated by OMS-19 and also store gasoline and diesel The fifth UST is located inside

the engineering yard near Building 1331 All of the tanks are reportedly of single-wall steel

construction The gasoline storage tanks are equipped with vapor recovery systems and are

permitted with AQMD Permit No C-1211-P-2 All of the tanks are reportedly precision3-13

GE.YSTEM

Consultants Inc
tested for tightness on an annual basis The capacities contents and locations of the five

currently active USTs are summarized in Table

3.2.2 Abandoned Underground Storage Tanks

Between April 1988 and May 1993 total of 171 USTs were excavated and removed from

Camp SLO most by PTS Environmental of Placer California PTS Environmental

undated The majority of the tanks previously contained heating oil and/or diesel fuel for

the heating systems at various buildings throughout the base The heating oil tanks were

reportedly installed by the Army in 1941 and were abandoned when the Army relinquished

ownership of Camp SLO to CA ARNG in 1965 Many of the heating oil tanks were

reportedly filled with water to maintain ballast In addition to the heating oil tanks

number of inactive motor vehicle fuel USTs were removed Excavations in number of

areas where USTs were known or suspected to have been located failed to find USTs

Apparently CA ARNG assumed that the USTs in these areas had already been removed

by the U.S Army However no records are available pertaining to any tank removals

carried out by the U.S Army

In addition to the documented removals of inactive USTs and/or the excavations to

ascertain whether the tanks were still present there are many other locations within the

former boundary of Camp SLO where USTs were very probably located As noted

earlier in this report great deal of land that was formerly part of Camp SLO has

been transferred to other state and local agencies and the property redeveloped Based on

the types of activities that occurred on these properties prior to the transfer it is highly

probable that USTs were operated on at least some However there are no records

pertaining to the removal or investigation of USTs prior to the redevelopment of these

properties Accordingly it is possible that there may still be inactive USTs and/or

residual contamination present beneath at least some of these properties Specifically

USTs may be present beneath property owned and/or occupied by CMC Cuesta College

and the County

3-14

GEYSTEM

Consultants Inc
As indicated in Table the majority of the UST sites investigated were relatively

uncontaminated and did not require further investigation or remediation following tank

removal Out of all the tank sites addressed by PTS the San Luis Obispo County Health

Agency Division of Environmental Health SLOCHA required additional investigation at

total of 28 former UST sites Geosystem conducted soil investigations at these sites during

October/November 1994 Eighteen of the sites did not show significant soil contamination

and SLOCHA does not require further investigation or remediation Based on the results

of the initial soil investigations Geosystem recommended limited soil removal and disposal

at of these 28 sites Sites 621 733 748 838 882 and 887 Geosystem November 23

1994 Geosystem conducted additional soil and ground water investigations at the

remaining five sites Sites 722 735 841 1328 OMS-19 and 1348 The additional

investigations indicated that relatively minor impacts to ground water had occurred at

Sites 735 841 and 1328 Based on the results of the additional investigations Geosystem

recommended limited soil removal and disposal at Sites 735 and 1328 Geosystem

September 14 1995 However in light of the pending SWRCB policy changes stemming

from the Lawrence Livermore National Laboratory study October 16 1995 of leaking

USTs in California Geosystem CA ARNG and the regulatory agencies are currently

reevaluating all of the diesel fuel/heating oil tank sites to determine whether active

remediation is in fact warranted Soil and ground water quality data from the UST site

investigations are included in Appendix

During previous UST work at Camp SLO Geosystem was informed that soil contamination

was encountered during subsurface utility repair work near former UST locations at Motor

Pool Building 888 and in the Engineering Yard Building 1331/1332 The USTs at

Motor Pool are known to have been removed by PTS however Geosystem has not

reviewed the results of any invert sample analyses conducted The USTs at the Engineering

Yard were removed in 1988 however the results of invert sample analyses if any were not

available for Geosystems review

3.3 ABOVEGROUND TANKS AND HUTMENT HEATING SYSTEMS

Motor vehicle fuels and heating oils have been stored in number of aboveground storage

tanks within the current and former boundaries Of Camp SLO Aboveground fuel storage

tanks and heating oil tanks are discussed in the following sections

3.3.1 Aboveground Fuel Storage Tanks

Motor vehicle fuels are known to have been stored in and dispensed from aboveground

tanks at the following locations

Former Caltrans META Yard

oCCC

Near borrow area on Santa Cruz Road

At the former Caltrans facility gasoline and diesel fuel were stored in rectangular doublewalled steel vaults This relatively recent storage tank design features integral dispensing

equipment and the interstitial space between the primary and secondary containment walls

is often filled with concrete

At the CCC construction yard diesel fuel and gasoline are stored in two aboveground steel

tanks The tanks are located on bermed concrete pad No visible leakage or stained soil

was observed by Geosystem personnel

An aboveground diesel fuel tank is located about 700 feet east of the Story Park landfill on

the north side of Santa Cruz Road No visible leaks or surface staining were observed by

Geosystem persoimel

3.3.2 Hutments Heating Oil Distribution Systems

Several hundred two-man hutments were constructed at Camp SLO for troop housing

during World War II Each hutment was equipped with small oil-burning stove for

heating purposes Heating oil and/or diesel fuel was supplied to each of these stoves via

shallow subsurface piping connected to an aboveground storage tank The fuel was

3-16

GEkYSTEM

Consultants Inc
delivered through the piping by gravity flow Typically about to 20 hutments were served

by each aboveground storage tank CA ARNG divides the hutments into 15 separate areas

designated as Hutment Areas through The locations of Hutment Areas through

are shown on CA ARNG map included in Appendix

On July 17 1987 truck ran over and damaged valve connected to the heating oil

distribution system in Hutment Area Note that several documents refer to this area as

Hutment Area but unless the designations for the hutment areas have changed in the

past these references appear to be incorrect This incident resulted in the release of

approximately 500 to 1000 gallons of diesel fuel to the ground surface The release

occurred just west of Sonoma Avenue south of Building 828 An investigation was

performed in January 1991 to delineate the extent of diesel-impacted soil Roy Weston

February 25 1991 The investigation indicated that the spill was limited to an area beneath

and around six of the easternmost huts The possible impact on ground water quality was

not investigated

On July 20 1987 SLOCHA conducted an inspection at Camp SLO As result of this

inspection two NOVs were issued to Camp SLO related to the hutment heating oil systems

The first NOV issued on July 21 1987 required assessment and remediation of the July 17

1987 diesel release discussed above The second NOV issued on July 23 1987 pertained

to visible soil contamination observed around the hutment heating oil distribution systems

throughout Camp SLO The July 23 1987 NOV ordered Camp SLO to cease and desist

use of the hutment heating oil distribution systems throughout the base The hutment

heating oil distribution systems were subsequently taken out of service and the aboveground

fuel storage tanks were removed total of 269 of the hutments at Camp SLO including

all of the hutments in Areas and were demolished as part of new barracks

construction project According to March 25 1993 quarterly environmental update for

Camp SLO the contractor for the new barracks construction project excavated and

relocated approximately 26000 cubic yards of contaminated soil In this regard it is

Geosystems understanding that the contractor stripped the upper to feet of soil from

3-17

GEYSTEM

Consultants Inc
the entire hutment area probably including large volume of uncontaminated soil in the

process An October 1993 quarterly environmental update indicated that Camp SLO

engineers were still in the process of discing the 26000 cubic yards of soil to promote

aeration/bioremediation

total of 593 hutments are still present at Camp SLO some of which are still in use

Although the aboveground storage tanks have been removed Geosystem personnel observed

that the underground heating oil piping is still in place in many of the remaining hutment

areas and in some cases is still connected to the hutments To date no soil or ground

water investigations or remediation have been performed in these areas Fifteen

aboveground storage tanks were removed by PTS Environmental in 1993 The former

locations of these tanks are listed in Table

Historical aerial photographs indicate that hutments were previously present at several other

locations within the current and historical Camp SLO boundaries Areas where hutments

appear to have been previously located include the following

Beneath the existing CMC East facility

Beneath the existing parade ground and Cuesta College campus This area

is bounded by Chorro Valley Road to the south Cuesta College Road to

the west and Dairy Creek to the east The northern edge of the former

hutment area was located about 700 feet south of and parallel to

Highway

South of Chorro Creek in an area bounded by Colusa Avenue to the north

Amador Avenue to the east Sutter Avenue to the south and Glenn

Avenue to the west

In the southwest corner of the cantonment area This area is bounded by

Tehama Avenue to the north Merced Avenue to the east Sutter Avenue

to the south and Mono Avenue to the west

The hutments were removed from these areas beginning some time after World War II All

of the hutments in these areas appear to have been removed by October 1973 So far as

3.4 ORGANIZATIONAL MAINTENANCE SHOP 19

OMS-19 is located in the eastern half of Building 1328 This facility provides maintenance

repair and support services to the various military units at Camp SLO Prior to occupation

by OMS-19 Building 1328 was an ordnance shop and was reportedly used as tank

maintenance facility In the past railroad spur was located on the north side of OMS-19

OMS-19 currently features vehicle maintenance bays one hydraulic lift three small partswashing tanks and hazardous waste storage area OMS-19 reportedly generates

approximately 800 gallons of waste.oil per year Mr Richard Rauenzalm March 1990

The hazardous waste storage area at OMS-19 consists of five metal storage sheds located

on concrete slab The storage sheds are purpose-built for storing hazardous materials and

their design incorporates secondary containment for potential container leakage or spills

The concrete slab is not bermed An emergency shower/eyewash station is located at the

western end of the hazardous waste storage area At the time of Geosystems May 17 1995

site visit the storage sheds and concrete pad were clean and no evidence of surface spills

was observed Hazardous wastes awaiting pick-up were segregated by type and included

waste oil waste fuel used batteries expired paint and miscellaneous automotive wastes

Potential sources of contamination at OMS-19 include primarily surface spills of fuel waste

oil grease battery acid antifreeze solvent and other wastes associated with vehicle

maintenance activities

In addition to the possible maintenance-related sources of contamination associated with

OMS-19 7500-gallon underground concrete heating oil bunker is located immediately

south of Building 1329 Fuel from this bunker was used to fire two large boilers in

Building 1328 and one boiler in Building 1329 Use of the tank was discontinued in the

1970s and it was subsequently filled with sand Soil and ground water beneath and around

concrete sump believed to be related to the fuel delivery system for the boilers is located

in Building 1328 near the former boiler locations

3.5 MOTOR POOLS AND OTHER VEHICLE MAINTENANCE FACILITIES

Vehicle maintenance facilities at Camp SLO have included motor pools vehicle wash racks

and vehicle grease racks In addition to these fixed facilities it is possible that minor

maintenance activities such as oil changes were performed elsewhere Also it is possible

that vehicles that broke down in the field were repaired on the spot Table presents list

of known former and existing buildings at Camp SLO that have been used for vehicle

maintenance and/or storage

3.5.1 Motor Pools

At least five motor pools are known to have existed in the past at Camp SLO although only

one Motor Pool is still in use The locations of the former and existing Camp SLO

motor pools are shown in Figure It is noted however that the motor pool reference

numbers go up to Motor Pool 11 possibly indicating that other motor pools may have

existed in the past None of these other possible motor poois are visible in the aerial

photographs reviewed by Geosystem nor do they appear on any of the historical plans

available to Geosystem It is possible that other motor poois may have been very short-lived

and consequently there are no records pertaining to them

Activities at the motor pools included primarily vehicle storage fueling and

maintenance/repair Potential sources of contamination include surface spills of fuel waste

oil grease battery acid antifreeze solvent and other wastes associated with vehicle

maintenance activities In addition each motor pool was originally equipped with fueling

station featuring one or more USTs

Geosystem has conducted subsurface investigation for the former USTs at Motor Pool

near Buildings 739 and 748 and is currently considering limited soil removal action at

3-20

GEYSTEM

Consultants Inc
the Building 748 location as discussed in Section 3.2.2 Similar removal actions are being

considered at the locations of former heating oil tanks associated with Buildings 882 and 887

in inactive Motor Pool Motor Pool is currently occupied by CDF CDF performs

vehicle maintenance and operates two USTs which are located near Building 962 Former

Motor Pools 10 and 11 were located on property currently owned by Cuesta College

The fueling stations associated with Motor Pools 10 and 11 were located beneath what

are now athletic fields and parking lot respectively During June 15 1995 site visit

Geosystem personnel observed what appeared to be vehicle maintenance area near

Building 536 former fuel station Construction vehicles belonging to the Operating

Engineers Trust were parked on concrete pad believed to be the foundation of former

Building 537 Several empty motor oil drums were also stored on this pad diesel tanker

truck was parked adjacent to Building 536

Geosystem personnel inspected Motor Pool on June 29 1995 Motor Pool consists

of one vehicle maintenance building Building 749 an oil storage shed Building 752 and

large paved parking area At the time of Geosystems site visit hazardous wastes awaiting

deliveiy to OMS-19 were stored outside and in Building 749 According to SGT Richard

Casper secondary containment overpack containers have been requested and will be used

in the future for drum storage The oil storage shed has concrete floor sump which is

reportedly closed and has to be drained manually Various automotive lubricants cleaners

battery acid and hydraulic oils were stored in the shed In addition 5-gallon Jerry cans

of gasoline and diesel fuel were stored in the shed Drummed materials including

antifreeze and lubricants are stored outside

3.5.2 Vehicle Wash Racks

Camp SLO is not equipped with vehicle washing facilities suitable for engine degreasing

Currently only rinsing of vehicle exteriors is permitted at Camp SLO According to

SGT Casper engine washing is currently performed at Caltrans facility in the city of

San Luis Obispo No specific information was available regarding past vehicle and engine

washing practices However these activities were typically carried out at concrete wash

observed wash rack behind OMS-19 Building 1328 Certain wash racks feature central

drain/sediment trap Runoff from the wash racks is typically discharged directly into

drainage ditches Table identifies known wash racks at Camp SLO and indicates their

current status

3.5.3 Vehicle Grease Racks

The 1952 plan of Camp SLO identifies 21 vehicle grease racks all of which have since been

demolished and removed The grease racks typically consisted of ramp leading to

horizontal platform with an open central area The open central area allowed access to the

underside of the vehicles by maintenance personnel Oil changes chassis lubricating and

other routine maintenance is typically performed at grease racks Known grease rack

locations at Camp SLO are listed in Table

3.6 UNITED STATES PROPERTY AND FISCAL OFFICE

The USPFO provides military equipment and supplies to CA ARNG units at Camp SLO

and elsewhere in California The location of USPFO is shown in Figure The USPFO

consists of an administrative building large warehouse and outdoor storage areas In

addition USPFO stores some vehicles in the motor pool area near Building 739 In the

past USPFO also stored items in the eastern portion of Motor Pool Figure

Hazardous materials stored in the warehouse include various lubricants paint cleaners and

adhesives Most of these materials are stored in small up to 15-gallon containers on

pallets in the warehouse At the time of Geosystems June 15 1995 site visit the warehouse

was very clean and no evidence of leakage or surface spills was observed Bulk materials

in 55-gallon drums were stored in fenced outdoor storage yard These materials include

primarily lubricating oil antifreeze and other vehicle maintenance materials No visual

indications of leaks or spills were observed by Geosystem personnel

Hazardous wastes are stored outside in the hazardous waste storage area Wastes generated

at USPFO reportedly consist of stored materials that have exceeded their shelf life and

materials that have been returned by various military units One hazardous waste storage

shed is designated for radioactive wastes Radioactive wastes generated at USPFO include

watches compasses and other field gear painted with minute amounts of radium or thorium

paint for luminosity SGT Dennis West June 15 1995

Potential sources of contamination at USPFO include surface spills of lubricating oils

greases paint cleaners and adhesives inside the warehouse and within the outdoor storage

yards There are no USTs associated with USPFO PCB-containing transformers were

reportedly improperly stored at USPFO in the past Section 3.10 Limited surface spills

of sodium hydroxide and motor oil have occurred in the USPFO yard and in the vehicle

storage area near Building 754 respectively Both of these spills were reportedly cleaned

up SGT Dennis West June 15 1995

3.7 ENGINEERING YARD

The Camp SLO engineering yard provides engineering maintenance and construction

support for the base It features heavy equipment maintenance shop paint shops

welding shop and utilities maintenance buildings paved vehicle storage area is located

near the entrance from Sutter Avenue single diesel UST and associated pump island are

located near the entrance Section 3.2.1. Hazardous materials stored at the engineering

yard include paint roofing adhesive Freon oxygen acetylene and pesticides Until

recently pesticides and herbicides were stored in Building 1343 An undated hazardous

materials inventory filed with the County indicated that commercial herbicide Round-Up

was the only pesticide/herbicide stored at the site at the time 1952 base map of Camp

SLO identifies Building 1354 as pest management This building no longer exists

review of historical base maps and aerial photographs suggests that this building was small

storage shed which was removed between 1972 and 1978

Geosystem personnel inspected the engineering yard on June 28 1995 Paints stains

and thinners were stored in several sheds and in cabinets inside Buildings 1349 and 1351

in the engineering yard and in Building 1357 in the warehouse area paint spray booth

3-23

GBYSTEM

Consultants Inc
is located in Building 1357 This spray booth reportedly does not meet current APCD

standards and has not been used for spray painting operations for at least year An

April 1994 environmental audit CA ARNG April 26 1994 indicated that Camp SLO had

recently submitted an application for paint spray booth permit and recommended that the

post commander limit painting operations to gallon per day until the permit was approved

Vehicle maintenance for heavy equipment and other vehicles in the engineering yard is

carried out in Building 1330 Hazardous wastes including motor oil oily rags and other

vehicular wastes are stored inside Building 1330 in 55-gallon drums pending transfer to

OMS-19 Motor oil and antifreeze are stored in small shed Building 1331 This building

features solid concrete slab floor with no sump or drain

Mr Ron Hammond was interviewed regarding pesticide/herbicide management practices

at Camp SLO He is currently in charge of overseeing contractor pesticide/herbicide

application and has worked at the engineering yard since 1982 Application was previously

performed by engineering yard personnel Pesticides and herbicides stored in Building 1343

and used at Camp SLO in the past reportedly include Round-Up Oust Princep Caliber 90

Monuron and Dursban Mr Hammond was unaware of pesticide/herbicide handling

practices prior to his employment at Camp SLO He indicated that pesticide mixing

operations were most likely performed in the engineering yard near the pesticide

storage area

3.8 FORMER LAUNDRY FACILITY BUILDING 1200

The Camp SLO laundry was formerly located in Building 1200 on Kansas Avenue This

large wood-frame building is currently used as warehouse by the San Luis Obispo County

Department of General Services Adjacent Building 1201 housed boilers that were

associated with the laundry It is likely that one or more fuel oil USTs were associated

with Building 1201 However no information regarding any tank removals at either

Building 1200 or 1201 could be located During an inspection of Building 1201 on

June 29 1995 Geosystem personnel observed 3-inch diameter vent pipe near the

GEYSTEM

Consu/tantsInc
southwest corner of the building The presence of the vent pipe indicates that USTs

associated with the boilers may still be in place similar boiler facility was located in

Building 389 which is now part of the CMC west facility On September 22 1987 three

8000-gallon fuel oil USTs were removed from this boiler facility by CMC SLOCHA

April 25 1991 The similarities in size and construction suggest that Building 1201

probably had similar number of tanks associated with it No vent pipes were observed

around Building 1200

Given the size and capacity of Camp SLO during U.S Army control it is possible that dry

cleaning facility was operated on the base However Geosystem did not find any specific

reference to dry cleaning operation in the records available Mr Brian Duke noted that

Building 1201 was similar in construction to the former dry cleaning facility at

Camp Roberts Mr Bob Nielsen County employee for 24 years works in the paint shop

in Building 1200 He recalled the boilers being removed from Building 1201 but did not

recall any UST removals All military equipment was reportedly removed and Building 1200

was vacant when it was acquired by the County Mr Nielsen did not recall any mention of

dry cleaning equipment in either Building 1200 or 1201 It is noted that RCRA hazardous

waste generator permit was issued for Camp SLO Building 1201 Section 2.4

3.9 FORMER AMMUNITION STORAGE AREA

Ammunition was stored at Camp SLO in number of bunkers located south of

Kansas Avenue Figure This area also identified as Area 17 is enclosed by chainlink

fence According to Camp SLO personnel this area is currently used for military training

exercises only and no ammunition is stored in the bunkers Mr Brian Duke May 17 1995

small separate area to the east of the main ammunition storage area is identified in

historical maps as chemical ammunition storage area No information was available

regarding the specific types and quantities of chemicals stored here However U.S Army

Corps of Engineers USACE study indicated that risk control and miscellaneous vomiting

tear agents are believed to have been present at Camp SLO Engineering-Science Inc

at either the chemical ammunition nor the main ammunition storage areas

3.10 POLYCHLORINATED BIPHENYLS PCBs

On Januaiy 30 1985 the EPA conducted an inspection and determined that PCB-containing

transformers awaiting disposal were improperly stored at Camp SLO Two transformers

were reportedly stored at Building 509 Figure and an unspecified number of

transformers were stored in the Camp SLO Storage Facility believed to be within the

current or former USPFO storage areas located in the eastern portion of Motor Pool

Both of these locations reportedly did not meet the design requirements for facility

used to store PCB items for disposal notice of noncompliance identifying the above

violations was issued by EPA on January 1986 The EPA notice required corrective

measures and requested plan for soil sampling outside Building 509 and within the storage

facility where PCB-containing transformers had been stored It appears that the soil

sampling and analysis requested by EPA was never conducted The transformers stored at

USPFO were reportedly stored inside building with concrete floor that was observed to

be cracked However there was no mention of visible leakage in the inspection report

Between 1986 and 1987 the State of California Office of the State Architect OSA

conducted PCB survey for the State Military Department This survey identified number

of PCB-containing electrical transformers at Camp SLO An OSA memorandum

summarized the results of PCB sampling at Camp SLO OSA February 26 1988

According to the memorandum total of 96 PCB-containing transformers had been

identified at Camp SLO Four of these transformers were identified as leakers Most of

the transformers were also considered to be safety hazards due to improper mounting and

lack of seismic shoring

EPA conducted follow-up investigation at Camp SLO on January 30 1990 The inspection

report indicated that no violations of federal PCB regulations were observed at Camp SLO

at that time The inspection report indicates that total of 83 PCB-containing transformers

from Camp SLO had been disposed of Another 24 PCB-containing transformers were still

3-26

GEYSTEM

in service at that time and Camp SLO reportedly planned to dispose of these transformers

before the end of 1990 No leaks were observed in the 24 transformers that remained in

active service at the time EPA March 19 1990

3.11 ASBESTOS

In March 1990 OSA completed an asbestos-containing materials ACM study of

239 buildings within the current Camp SLO boundaries Of the buildings investigated OSA

reported 124 structures containing at least one known type of ACM from list of 19 ACM

types found on the base Some of these materials included pipe and thermal insulation

floor and ceiling tiles wall and ceiling plasters sheetrock or gypsum paneling Transite

siding and sheeting tank and wire insulation HVAC flex joints fireproofing panels and

pipe fittings OSA March 1990

To help categorize the levels of concern for each building containing ACMs OSA

established its own algorithm ranking system based on the immediate short-term or longterm health concern associated with each ACM found Based on the survey the following

buildings were identified as being an immediate health concern

OMS-19 Building 1328

Administration Building 904

Theater Building 900

Twenty-one general storehouse buildings

The buildings that were listed as short-term concern included

Supply Building 700

Ten maintenance shop buildings

ACM surveys for Camp SLO buildings were conducted by EPA-accredited building

inspectors using the identification sampling and analysis procedures established under

40 CFR Part 763 OSA March 1990 March 26 1991 quarterly environmental update

for Camp SLO stated that all high-risk asbestos containing material with the exception of

Building 900 has been abated The update stated that Building 900 was scheduled for

abatement in fiscal year 1991 An October 1993 environmental update indicated that

asbestos abatement of hot water heater in Building 504 was scheduled

number of buildings and hutments at Camp SLO feature potentially asbestos-containing

roofing shingles and siding These ACMs are not considered friable and do not appear to

pose significant or immediate threat to building occupants Some of the shingles are in

relatively poor condition and have come loose from these buildings

3.12 RANGE AND IMPACT AREAS

Throughout its history as military installation Camp SLO has featured various weapons

firing ranges impact areas and training areas Unexploded ordnance UXO from former

military activities at the base has been found within all of the current CA ARNG ranges on

the post Explosive ordnance has also been found on property currently occupied by

Cal Poly El Chorro Regional Park SLO County Board of Education and the U.S Forest

Service UXO discovered in these areas has included mortar and rocket rounds hand and

rifle grenades anti-tank mines and fuses phosphorous grenades and various artillery rounds

UXO used recently at Camp SLO by CA ARNG includes light anti-tank weapon LAW

rounds hand grenades C-4 M-31 and M-79 USACE April 1995

Several areas within the current and former Camp SLO boundaries have been swept for

UXO In particular most of the inactive range areas reportedly have been swept for UXO

except for 250-acre portion of El Chorro Regional Park However ordnance is repeatedly

found in previously swept areas This is apparently due to erosion of the overlying soil

which exposes previously buried ordnance USACE April 1995 During August 1994

much of the northernmost Camp SLO property and adjacent U.S Forest Service land was

3-28

GBYSTEM

Consultants Inc
burned during large brush fire During the fire numerous explosions were reportedly

heard at Camp SLO and neighboring properties These explosions were presumed to be

UXO that exploded as result of exposure to the intense heat of the fire In addition to

destroying much of the natural vegetation cover the fire exposed the steep mountain slopes

to unusually intense erosion It is possible that this erosion will expose more UXO

risk assessment for ordnance and explosive waste OEW sites at Camp SLO was

prepared by Engineering Science Engineering Science July 10 1992 as part of the Defense

Environmental Restoration Program DERP study for Camp SLO The OEW risk

assessment is based on documented evidence pertaining to confirmed or potential

unexploded ordnance discoveries The risk assessment is composed of two site-specific

factors -- hazard severity and hazard probability For Camp SLO both the hazard severity

and probability were determined to be in the highest possible category Hazard severity was

designated catastrophic primarily due to the presence of hand grenades artillery rounds

white phosphorus containers and risk control chemical agents such as tear gas Hazard

probability was designated frequent due to the presence of many nearby structures

including educational facilities uncontrolled access to certain OEW areas and site dynamics

such as excessive soil erosion and increasing land development These two factors are

compared and used to assign risk assessment code RAC to the site An RAC of was

assigned to Camp SW RAC is defined as Imminent Hazard-Emergency action required

to mitigate the hazard or protect personnel The OEW risk assessment is included as

Appendix to this report

Numerous small arms firing ranges have been operated throughout Camp SLOs history as

military installation The five currently active small arms ranges are located along the

north side of Range Road at Camp SLO Former ranges were present north of Pennington

Creek Road on El Chorro Regional Park and Cal Poly property and north of Gilardi Road

on Cal Poly and DFG property The DFG continues to operate public firing range on

former Camp SW property Environmental hazards at these ranges include lead projectiles

within the upper few feet of soil and potentially live small arms ammunition

3.13 INCINERATOR

large garbage incinerator identified as Building 1213 is located at Camp SLO

Construction plans for this incinerator were reviewed at Camp SLO by Geosystem

personnel The plans indicate that the incinerator is forced-draft air type and was

probably constructed in the late 1920s The time of construction suggests that the

incinerator was built by CA ARNG as it predates U.S Army operation of Camp SLO

Geosystem personnel inspected the incinerator on June 29 1995 No evidence of any

surface contamination was observed in or around the incinerator No evidence of any fuelfired burner system was observed which is consistent with the construction plans reviewed

The dates of operation for the incinerator are unknown No evidence of landfihling at

Camp SW prior to the 1940s has been found The presence of an incinerator on the base

as early as the late 1920s suggests that CA ARNG may have burned the majority of the

solid wastes generated at Camp SW No information was available regarding the disposal

of noncombustible waste or ash by CA ARNG

3.14 WASTE WATER TREATMENT FACILITY

wastewater treatment facility reportedly constructed by the U.S Army in 1940 is located

in the southwest corner of Camp SW The facility has been operated by CMC since 1961

Discharge from the facility is regulated by the RWQCB under National Pollutant Discharge

Elimination System Permit No CA04447856 The facility is permitted to handle up to

1.2 million gallons per day of designated domestic sewage and industrial waste Natec

April 1995 In addition to Camp SLO the facility currently treats wastewater from

CMC Cuesta College El Chorro Regional Park and various County facilities CMC

February 1995

The area served by the facility includes approximately 13000 acres with projected 1997

population of 16250 Of the 13000 acres within the service area approximately 11700 are

public lands with the remainder being used for private agriculture The original plant

to Chorro Creek or is reclaimed by Cal Poly for irrigation of university-owned farmland

CMC Februaiy 1995

Geosystem personnel interviewed Mr Michael Valverde on June 15 1995 regarding

operation of the sewage treatment plant Mr Valverde has been the plant operations

manager since 1983 There reportedly have been no environmental problems at the plant

related to discharge from Camp SLO during the last 12 years of operation In the past

some sludge was reportedly disposed on land adjacent to the sewer plant Some sludge has

also reportedly been used for landscaping at CMC or given to Cal Poly for use as fertilizer

Mr Valverde indicated that CMC is responsible for maintenance and operation of all sewer

mainlines at Camp SLO and CA ARNG is responsible for all lateral sewer lines

3.15 LEAD-BASEDPAINT

Most of the structures present at Camp SLO were built during the 1940s During this time

period lead-based paint was commonly used on both interior and exterior building surfaces

The use of lead-based paint in most structures was subsequently banned by EPA because

of potential health risks Geosystem is not aware of any lead-based paint studies performed

at Camp SLO Due to the age of the structures at Camp SLO however it is considered

likely that some contain lead-based paint

3.16 INACTIVE MINES

In 1870 significant chromite deposits were discovered in the main ridge of the Santa Lucia

Range between Cuesta Pass and Morro Creek These deposits were mined in the late 1800s

and reportedly were also actively mined during World Wars 1916 to 1920 and 111942

to 1945 The chromite deposits of the region are reportedly not rich or large enough to

3-31

GBYSTEM

Consultants Inc
be economically mined during normal times Past production occurred either before the

discovery of large foreign deposits or during war emergency periods USGS 1944

In December 1993 the RWQCB issued report on study of inactive metal mines in the

northern quarter of San Luis Obispo County The study was conducted under the direction

of Mr David Schwartzbart of the RWQCB total of 217 mines were inventoried of

which 89 were considered to pose some environmental concern The study identified

approximately 14 small prospect mines as well as larger mines located within the current

Camp SLO boundary The three larger mines are the La Trinidad Pick and Shovel and

Prirnera mines The La Trinidad mine is located on current Camp SLO property near the

head of the west branch of Chorro Creek The La Trinidad mine consists of open pits and

underground workings During early periods of production and in 1917/1918 the La

Trinidad Mine was reportedly one of the larger producers in the area The portals to the

underground workings are inaccessible due to caving USGS 1944 The Pick and Shovel

mine is also located on current Camp SLO property near the head of the central branch

of Chorro Creek and is entirely an underground mine developed on several levels The

Pick and Shovel mine is reportedly one of the oldest mines in the area having produced

considerable quantity of chromium ore between 1870 and 1890 U.S Department of

Agriculture Soil Conservation Service April 1994 At least 6000 short tons of ore were

produced from the Pick and Shovel Mine between 1917 and 1920 Activity at the mine after

World War was reportedly mostly exploratory in nature USGS 1944 The Primera and

New London mines are also located within the current Camp SLO boundary Little

information regarding the Primera mine is available The New London mine is one of the

oldest mines in the region An unknown quantity of ore was produced before 1900 and

3500 long tons of ore were shipped from the mine during World War

The Castro mine and number of other smaller mines and prospects are located within the

historical Camp SW boundary The Castro mine workings reportedly consist of four large

open cuts several bulldozer trenches and four levels of underground workings The

bulldozer trenches and underground workings were made during exploratory work carried

out by the U.S Bureau of Mines in the Fall of 1941 USGS 1944 It is estimated that

6000 long tons of ore were removed from the Castro Mine between 1870 and 1944 fifty

ton concentrating mill was constructed at the site and operated during World War No

specific information was available regarding operation of the smaller mines The primary

material produced from these mines was reportedly chromium ore Other metals including

copper iron and nickel have also been produced from some of the mines RWQCB

December 1993

Of the mines that were classified by the RWQCB as potential polluters only 12 were

located within the Chorro Creek watershed RWQCB December 1993 Of these 12 mines

are located within the current Camp SLO boundaiy and an additional are located within

the historical Camp SW boundary As part of its study sediment from Chorro Creek was

sampled and analyzed for total metals by the RWQCB The analyses indicated that the

sediment samples contained elevated concentrations of total chromium nickel and

magnesium Also water samples collected from Chorro Creek contained higher levels of

antimony copper nickel and nitrogen than samples from three other potentially impacted

watersheds Because the Chorro Creek area mines are derived from serpentinized

ultramafic mineral deposits and not from sulfide deposits there is no significant threat of

acid mine drainage occurring in this region Therefore heavy metals existing in tailings

from these mines are expected to remain in an insoluble state RWQCB December 1993

4.0 PAThWAY AND ENVIRONMENTAL HAZARD ASSESSMENT

This section presents an evaluation of potential contaminant migration/exposure pathways

in ground water surface water air and soil

4.1 GROUND WATER

The ground water pathway at Camp SLO is discussed in the following sections in terms of

Camp SLOs geologic setting hydrogeologic conditions ground water use the potential

impact of hazardous substances on ground water and migration pathway evaluation

4.1.1 Geologic Setting

Camp SLO is located in the southern end of the Santa Lucia Range portion of the Coast

Ranges Physiographic Province of California The northwest-trending Santa Lucia Range

consists predominantly of complex metavolcanic and metasedimentary terrain assigned to

the Jurassic-age Franciscan Formation Bedrock assemblages exposed locally in the adjacent

hills include graywackes greenstones cherts blue schist facies conglomerate and

serpentinite These units have been pervasively sheared and are part of the Franciscan

melange characteristic of the Salinian structural block in the westerly Coast Ranges

Collectively the Coast Ranges are part of the Circum Pacific Orogenic Belt where large

blocks have been deeply subducted metamorphosed sheared and then brought back to the

surface by transform faulting processes

The developed portion of Camp SLO is centered along the Chorro Creek valley about 7.1

miles east of the coastline Chorro Creek has eroded and flowed westward across the Santa

Lucia Range as it has been uplifted The drainage course projects parallel to the regional

northwest-trending structural fabric The fabric is well expressed not only in the regional

drainages but also in the uplands where numerous northwest-trending folds and faults have

been identified The Chorro Creek valley is up to mile wide in the site vicinity and is

mantled with alluvium derived from the adjacent uplands The alluvium consists mainly of

unconsolidated sandy and silty interlayers and lenses that extend to depths of about 100 feet

4-1

GE.YSTEM

Consultants Inc
Bedrock underlying the alluvium consists of the Franciscan Formation and is similar to the

rock types exposed in the adjacent hills

4.1.2 Hydrogeologic Conditions

Much of Camp SLO is situated in the Chorro Creek ground water basin This basin

consists of the unconsolidated alluvial deposits associated with Chorro Creek and its

tributaries As such the basin is narrow and irregular in shape extending from just east of

Camp SLO to the Pacific Ocean at Morro Bay

Ground water in the Chorro Creek basin occurs under unconfined conditions in

relatively shallow zone of saturated alluvium overlying Franciscan Formation bedrock The

Franciscan Formation bedrock is fractured and saturated but yields little water

Consequently it is generally considered to define the boundaries of the ground water

basin Staal Gardner Dunne Inc June 1989 Ground water in the alluvial deposits

generally flows to the northwest parallel to the axis of Chorro Creek before discharging

into the Pacific Ocean near Morro Bay Recharge to the basin is generally attributable to

the infiltration of precipitation Ground water in the basin has been developed locally for

domestic municipal and agricultural water supply purposes Three water supply wells are

located within the historical boundaiy of Camp SLO Section 4.1.3

As noted above the Franciscan Formation bedrock yields relatively small quantities of

water however few water supply wells have been completed in it Where the Franciscan

Formation outcrops in the flanks of the valleys numerous springs have been identified

These springs are not considered to be directly related to the alluvial aquifer however it

is reasonable to assume that below the ground surface there is hydraulic communication

between the water in the fractured bedrock and that in the overlying/adjacent alluvium

4.1.3 Ground Water Use

Three water supply wells Wells No and are present within the current and former

boundaries of Camp SLO Well No is located at the County Government Center near

former Building 609 and Wells No and are located within the current Camp SLO

cantonment area near Buildings 1336 and 1526 respectively The locations of Wells No

and are shown in Figure All three wells were installed prior to 1949 and are used

to supplement the water produced at the Chorro Reservoir water treatment plant Wells

No and are reportedly used only intermittently Well No is reportedly very shallow

and is rarely used due to insufficient yield Mr Bill Cook June 1995 Well No can

reportedly yield approximately 150000 gallons per day about 104 gallons per minute

Water produced by the three wells is chlorinated at the wellhead and added to the water

supply without further treatment or filtration Water quality from all three wells is

reportedly very good however recent high bacteria counts have reportedly resulted in

temporarily taking Well No out of service Mr Bill Cook June 1995 During 1989

Wells No and provided 55 and 108 acre-feet of water respectively accounting for

approximately and 10 percent of the drinking water supplied by CMC Ecology and

Environment Inc May 10 1991

The County Engineering Department provided data on Wells No and Well No

features 12-inch diameter casing and its total depth is 50.7 feet below grade pumping

test conducted in September 1968 showed that the well maintained pumping rate of

500 gallons per minute gpm after 24 hours No construction or pump test data are

available for Wells No and Water level data for the three wells are summarized below

Ground Water Network Data Base Search was requested from the National Groundwater

Information Center in Dublin Ohio to provide information on the population served by

various drinking water sources within given zip code Camp SLO has its own zip code

93403 for mailing purposes however the database does not provide specific data for zip

codes that represent large business or post office box Accordingly the database was

queried for the zip code 93405 which surroundst Camp SLO This zip code includes the

western portion of the city of San Luis Obispo eastern Los Osos Valley and most of the

Chorro Creek basin The zip code extends west to the Morro Bay city limits summary

Most of the households within this zip code are located within the western portion of the

city of San Luis Obispo Drinking water for the city of San Luis Obispo is reportedly

combination of surface water and ground water However none of the municipal

production wells are located within the Chorro Creek basin Ecology and Environment

DWR and are summarized in Table In addition to the wells included in Table the

City of Morro Bay reportedly operates number of municipal water supply wells at the

western end of the Chorro Creek basin several miles downgradient of Camp SLO In brief

the Chorro Creek basin is major source of water for most of the population between

Camp SLO and the coast It is noted that the lower portion of the basin reportedly has

been in overdraft for many years resulting in sea water intrusion near the coast

4.1.4 Potential Impact of Hazardous Substances on Ground Water

Hazardous substances released to soil have the potential to migrate into ground water

Hazardous substances impacting ground water have the potential to raise the concentrations

of dissolved constituents above the corresponding applicable MCLs and/or ALs rendering

the water unsuitable for drinking The wells most likely to be impacted by possible releases

to ground water are the three on-site water supply wells and private wells located

immediately downgradient of Camp SLO Releases with the highest potential for impacting

ground water are those occurring in the subsurface from landfills or USTs Other possible

release mechanisms would include leaks from the sewer lines located throughout Camp SLO

or significant surface spills

4.1.5 Migration Pathway Evaluation

None of the known releases to ground water at Camp SLO appear likely to migrate off site

i.e beyond the current boundaiy of Camp SLO Known releases from USTs which include

primarily diesel fuel or fuel oil are limited in area extent and have not exceeded any MCLs

or ALs The toluene concentrations detected at the Kansas Avenue landfill were well below

the corresponding AL Production Well No although located adjacent to the Kansas

Avenue landfill produces water of good quality and has not shown detectable concentrations

of VOCs VOC concentrations detected in wells downgradient of the Sutter Avenue landfill

exceeded the MCL for carbon tetrachioride However the concentrations are very low and

VOCs released from the Sutter Avenue landfill do not appear to pose significant threat

to on-site or off-site water supply wells

Camp SLOs hydrologic setting surface water bodies surface water use potential impact of

hazardous substances on surface water and migration pathway evaluation

4.2.1 Hydrologic Setting

Camp SLO as defined by its current boundary lies entirely within the Chorro Creek

drainage basin Chorro Creek originates on the southwest face of Cuesta Ridge in the

northeastern corner of Camp SLO It flows through Chorro Reservoir located on

Camp SW property 0.75 miles northeast of the CMC east facility west-northwest through

the cantonment area and discharges into Morro Bay approximately miles to the northwest

Major tributaries flowing into Chorro Creek within the Camp SLO boundaries are Dairy

Creek and Pennington Creek Within the Camp SLO boundaries Chorro Creek is an

intermittent stream which is usually dry during the summer season

Small areas within the former boundaries of Camp SLO are within the Tassajara Creek and

Stenner Creek watersheds The former areas of Camp SLO within these watersheds were

not developed but may have been within one or more firing fans

4.2.2 Surface Water Bodies

Surface water bodies at Camp SLO include Chorro Creek and its tributaries and Chorro

Reservoir which was formed when the U.S Army dammed Chorro Creek in the 1940s

Chorro Reservoir is located near the eastern boundary of Camp SLO about 1.3 miles

northwest of Highway and about mile north-northwest of the CMC Chorro Reservoir

is fed by Chorro Creek and by two smaller tributaries During U.S Army operation of

Camp SLO Chorro Reservoir was also fed by an aqueduct that delivered water from the

Salinas Dam Santa Margarita Lake Due to the smaller population now served by the

system water is no longer delivered through this aqueduct Water from Chorro Reservoir

is treated at the CMC filtration plant and constitutes the water supply for CMC Camp SW

Cuesta College and adjacent facilities Reportedly the construction of Chorro Reservoir

in the 1940s reduced the downstream flow in Chorro Creek to 2.78 cubic feet per second

cfs although it is not clear exactly where downstream of the reservoir this measurement

was taken This flow rate was reportedly insufficient to support the fish population that

would normally inhabit Chorro Creek Currently CMC is required to discharge even less

cfs from Chorro Reservoir in an effort to maintain flow through Chorro Creek Ecology

4-6 GE

Consultants Inc
and Environment Inc has reported May 10 1991 that the cfs release generally

disappears into the bedrock fractures within about 300 yards of the dam In addition

minimum flow of 0.5 cfs is discharged into Chorro Creek from the wastewater treatment

plant in an effort to support steelhead trout CMC February 1995 During the dry season

some stagnant standing water is present within the creek bed at Camp SLO

4.2.3 Surface Water Use

CMC operates water filtration plant at Chorro Reservoir This facility treats water from

Chorro Creek and its tributaries upstream of the reservoir using filtration and chlorination

Water from the plant is used to supply CMC Camp SLO Cuesta College County facilities

and other adjacent facilities According to Mr Bill Cook the CMC filtration plant operator

the plant has maximum pumping capacity of about million gallons per day and supplies

water to an estimated maximum population of 25000 The water supply for Camp SLO and

adjacent facilities is also supplemented by water from Whale Rock Reservoir located

about 12 miles northwest of Camp SLO near the town of Cayucos

Another filtration plant is located on Stenner Creek Road approximately mile east of the

Chorro Reservoir plant This facility reportedly provides drinldng water to the city of

San Luis Obispo It is noted that this facility is located within the Stenner Creek

rather than Chorro Creek watershed Only very small undeveloped portion of historical

Camp SLO lies within the Steimer Creek watershed

Because of the low flow rate recreational fishing in Chorro Creek is very limited At most

the total fish catch for Chorro Creek would be several hundred pounds during wet year

During drought years it is considerably less Ecology and Environment May 10 1991

4.2.4 Potentially Sensitive Receptors

Chorro Creek discharges into Morro Bay which has been proposed for inclusion in EPAs

National Estuary Program by the Morro Bay Interagency Task Force Ecology and

Environment May 10 1991 There are no known surface water intakes on Chorro Creek

downstream from Camp SLO Ecology and Environment May 10 1991 Camp SW

receives drinking water from the CMC Chorro Reservoir plant The only potential releases

identified within the upper Chorro Creek watershed upstream from Chorro Reservoir are

UXO and the abandoned mines Drinking water from the CMC plant is routinely tested

for hazardous constituents There have been no reported instances of contaminants related

to UXO or abandoned mines in the water extracted from Chorro Reservoir Sediments in

Chorro Reservoir as elsewhere in the Chorro Creek basin contain elevated concentrations

of chromium and other metals However the metals occur in an insoluble state and

elevated concentrations of dissolved metals have not been detected in the waters of Chorro

Creek Section 3.16

4.2.5 -Potential Impact of Hazardous Substances on Surface Water

Surface releases of hazardous substances have the potential to migrate into surface water

bodies directly or indirectly though storm drains In addition contaminated ground water

has the potential to discharge into surface streams when the water table is high

Contaminants entering surface water bodies could raise constituent levels above applicable

MCLS and ALs rendering the water unsuitable for drinking In addition plant and animal

populations downstream of the source area could be exposed to contaminants

4.2.6 Migration Pathway Evaluation

There have been no known releases of hazardous substances into surface water bodies at

Camp SLO Known releases to ground water are not believed to pose threat to surface

water bodies at this time Waste water from Camp SLO receives primary and secondary

treatment at the CMC waste water treatment plant The secondary treatment process

includes chlorination and dechlorination CMC February 1995 CMC has not reported any

problems related to waste discharges from Camp SLO The only known surface water

intake on Chorro Creek is the Chorro Reservoir filtration plant operated by CMC There

are no known or suspected hazardous substance releases upstream of the Chorro Reservoir

intake that could adversely impact water quality Sediments containing elevated

concentrations of chromium and other metals are present within the Chorro Creek basin

Some of these sediments may be derived from mine tailings however there is no evidence

that these sediments have adversely impacted surface water quality in or downstream of

Chorro Creek There is no evidence that past or present operations at Camp SW have

adversely impacted Chorro Creek or other surface water bodies

There are number of confirmed and potential sites within the current and former

Camp SLO boundaries where hazardous materials may have been released to soil

Confirmed releases to soil include at least 10 UST sites the Sutter Avenue landfill the

hutment heating oil distribution systems UXO located in the current and former range

areas and an oil spill in the USPFO vehicle storage area Potential releases to soil are

associated with pesticide and paint handling areas in the engineering yard Story Park

Kansas Avenue and Pemiington Creek landfills and former PCB-containing transformer

storage sites at USPFO and Building 509

Sampling results from UST sites investigated by Geosystem are included in Appendix

Remediation at ten UST sites is being considered by Geosystem and the regulatory agencies

however the documented soil contamination does not pose an immediate or serious threat

to human health and/or the environment There have been no soil sampling activities

around the remaining hutments engineering yard USPFO Building 509 or the range areas

The confirmed and potential releases at the four landfills have been investigated by

Geosystem and are not believed likely to pose significant threat to human health and/or

the environment

4.3.1 Population Distribution

The on-site population at Camp SLO varies greatly due to the intermittent nature of

training operations At the time of the PA investigation there were only two permanent

residents at Camp SLO The permanent worker population is about 300 of which

40 are CA ARNG employees USPFO has 160 permanent employees and the remaining

military and non-military tenants employ an additional 100 workers Ms Sylvia Brown

July 18 1995 However the transient population at Camp SLO can be as high as 2000

during busy training periods particularly during the summer months For the period 1991

through 1993 the average troop population at Camp SLO during active use days was 700

population change report was ordered from Claritas Inc of Ithaca New York The

report Claritas Inc June 23 1995 shows populations located within 1- 2- and 4-mile radii

of xed point The approximate center of the cantonment area was selected as the center

point for the survey Populations are summarized below

4.3.2 Potentially Sensitive Receptors

There are no schools day care facilities or residences within 200 feet of known or suspected

releases to soil Cuesta College operates small day care/early childhood development

center near the CCC area in Buildings 1518-1520 This facility is located approximately

1600 feet north of the Sutter Avenue landfill The County operates educational facilities

along Pennington Creek Road These facilities are approximately 750 feet northeast of the

Pennington Creek landfill Cuesta College is located immediately northwest of the main

cantonment area The nearest off-site residence is located 900 feet southeast of the Sutter

Avenue landfill The County animal control facility is situated directly over the Kansas

Avenue landfill

4.3.3 Potential Impact of Hazardous Substances on Soil

Hazardous substances released to soil pose potential threat to persons on or near the site

who may come into contact with exposed wastes or areas of suspected contamination

Access to potentially contaminated sites is generally unrestricted Potential routes of

exposure include direct skin contact ingestion of soil and migration of the hazardous

substances in gaseous or particulate form Contaminants in soil also can potentially leach

into ground water or surface water

4.3.4 Migration Pathway Evaluation

Soil contamination resulting from UST leaks is covered by either uncontaminated soil

native vegetation or pavement The potential for direct exposure to contaminated soil

would occur only during excavation for remediation construction or subsurface utility work

As shown in Appendix the majority of the UST leaks involved heavier nonvolatile

hydrocarbons such as diesel and fuel oil Consequently the potential for these compounds

to migrate in gaseous or vapor form is negligible

Wastes buried in the four landfills at Camp SLO are covered by soil and native vegetation

minimizing the risk of direct exposure to waste materials or potentially impacted soil Soil

contamination at the Sutter Avenue and Kansas Avenue landfills has not been directly

4-11

GE4YSTEM

Consultants Inc
evidenced but rather is inferred due to the presence of impacted ground water beneath the

landfffls final cover will be constructed over the waste disposal area at the Sutter Avenue

landfill during the summer of 1996 The final cover is expected to significantly reduce the

risk of direct exposure to waste materials at the landfill and should greatly reduce the

potential for leaching

Near-surface soils around the remaining hutment areas at Camp SLO have potentially been

impacted by releases of diesel and/or heating oil These areas are typically unpaved and

feature either gravel or native soil cover It is noted that some of the hutments are still

used as temporaiy housing for military personnel Other potential areas of near-surface soil

contamination include pesticide and paint handling/storage areas in the engineering yard

former PCB-containing transformer storage areas at USPFO and Building 509 and

number of former and existing grease racks wash racks and vehicle maintenance areas

within the current and former boundaries of Camp SLO

4.4 AIR

Geosystem personnel did not observe any significant releases of hazardous substances to air

at Camp SW APCD does not have any record of citizen complaints or incidents related

to potential releases of hazardous substances to air at Camp SLO

4.4.1 Potential Air Contaminants

Potential air contaminants at Camp SW include methane gas and VOCs from the landfills

tear gas from training exercises paint and solvent vapors and compressed gases stored in

cylinders Tear gas used at Camp SLO for military and law enforcement training purposes

is generally released inside an enclosed structure Personnel potentially exposed to tear gas

during training exercises are outfitted with appropriate protective gear Painting operations

are generally limited to hand-painting and only limited volume of paint is used at any one

time The paint spray booth located in Building 1341 is not currently used for spray painting

operations Gases stored in compressed gas cylinders at Camp SLO include argon oxygen

nitrogen acetylene Freon and chlorine 1000-gallon propane tank is located in the CDF

GEYSTEM

Consultants Inc
yard near Building 961 Quantities of other compressed gases are generally limited to small

portable cylinders

4.4.2 Migration Pathway Evaluation

Geosystem conducted landfill gas sampling at the Story Park Kansas Avenue and

Pennington Creek landfills on January 31 and February 1995 The data did not indicate

significant methane concentrations in soil gas at these landfills Appendix landfill gas

study performed at the Story Park and Sutter Avenue landfills in 1988 did not show

significant methane or VOC concentrations within or around these two landfills USAEHA

December 20 1989 Documented UST releases at Camp SW primarily involve diesel fuel

or heating oil These substances have low vapor pressure and vapors are unlikely to be

released to air in significant quantities Open burning or incineration of trash is no longer

practiced at Camp SLO

5.0 FINDINGS AND RECOMMENDATIONS

Based on the information gathered and evaluated during the PA there are

14 confirmed sites within the historical boundary of Camp SW where hazardous materials

have been released to the environment including 10 individual UST sites The PA data also

indicate many other sites where the potential exists for hazardous material releases At

most of these potential sites the materials that may have been released are petroleum oil

and lubricants POLs that are probably not subject to regulation under CERCLA Some

of the potential sites may however warrant further investigation under state and/or local

regulatory agency programs

The following sections briefly summarize conditions at individual or groups of confirmed

release sites and present Geosystems recommendations pertaining to further investigation

and/or remediation Summaries of conditions are also presented for those potential release

sites at which additional investigations may be warranted

5.1 CONFTRMED RELEASE SITES

Sites at which hazardous materials releases have been confirmed are the Sutter Avenue

landfill the Kansas Avenue landfill the hutment heating systems in Area the former

firing ranges and firing fans and number of UST sites

5.1.1 Sutter Avenue Landfill

The Sutter Avenue landfill is an inactive Class Ill landfill located on the southern border

of Camp SLO The landfill is believed to have been operated by the CA ARNG from

around 1970 to 1985 using the trench and cover method Some of the waste disposal

trenches reportedly encountered ground water raising the possibility that disposed wastes

may be in direct contact with ground water The wastes disposed of in the Sutter Avenue

landfill were primarily municipal-type waste and construction debris In some area the

interim earthen cover allows water to pond over and infiltrate the disposed wastes In

response to request from the RWQCB which regulates the landfill via waste discharge

5-1

GEkYSTEM

ConsuitantsInc
requirements CA ARNG is currently implementing remedial grading program to remedy

this condition

Ground water beneath and hydraulically downgradient of the Sutter Avenue landfill has

been impacted by 14-dichlorobenzene CTC and chloroform Although veiy low the

concentrations of these constituents in some wells are above the corresponding MCI_S

final closure and postclosure maintenance plan has been prepared and CA ARNG plans to

construct an engineered final cover over the landfill in the summer of 1996 The final cover

is expected to minimize the infiltration of surface water through the disposed waste and will

constitute the corrective action required under state regulations

Because of the nature of the source and the types of contaminants involved the Sutter

Avenue landfill is potentially subject to CERCLA However investigations at the landfill

are ongoing and are already well beyond the SI phase In addition final closure/corrective

action is imminent Accordingly Geosystem does not recommend any additional

investigations or response measure over and above those already planned or in progress

5.1.2 Kansas Avenue Landfill

The Kansas Avenue landfill is closed solid waste disposal facility located immediately

south of Highway on land now owned by the County The landfill is believed to have

been operated by the U.S Army from around 1941 to around 1956 using the trench and

cover method There are few records pertaining to the types of waste disposed of in the

Kansas Avenue landfill however municipal-type waste is the most likely During World

War comprehensive recycling program reportedly precluded the disposal of scrap metal

and other recyclables After the war however some paint and lubricant containers and dry

cell batteries were reportedly disposed Sometime between May 1975 and 1977 the County

constructed an animal shelter directly over the eastern edge of the landfill Part of the

subsequently constructed County Sheriff center overlies the northeast corner of the Kansas

Avenue landfill although none of the County Sheriff buildings directly overlie the landfill

Note that in the past the Kansas Avenue landfill has been referred to as the County landfill

5-2

GESYSTEM

Consultants Inc
or as the Animal Shelter landfill The landfill currently features an uneven earthen cover

of unknown thickness Surface water very likely ponds over and infiltrates into the

disposed wastes

Subsurface investigations at the Kansas Avenue landfill have included the installation of

ground water monitoring wells and suction lysimeters soil sampling and analysis soil gas

sampling and analysis and surface water sampling and analysis The only indication that

waste disposal operations at the Kansas Avenue landfill may have impacted the surrounding

environment is the reported presence of toluene in ground water samples collected from

Wells MW-3 and MW-4 The reported concentrations of 0.0013 and 0.0029 mg/t are well

below the state AL for toluene of 0.100 mg/L Note that only one round of ground water

monitoring has been conducted to date Geosystem believes additional monitoring should

be conducted There is water supply well Well No immediately north of the Kansas

Avenue landfill Well No contributes to the water supply for Camp SLO CMC and

other facilities Water quality samples from Well No are collected and analyzed on

frequent basis Neither toluene nor any other organic constituent has been detected in any

of the samples Note that ground water has been measured as shallow as foot below the

ground surface in some areas of the landfill Based on this shallow water table it is likely

that disposed wastes are beneath the water table at least during seasonally high water table

conditions

Because of the nature of the source the Kansas Avenue landfill is potentially subject to

CERCLA However investigations at the site are already well beyond the SI stage and

additional investigations will likely be required by the RWQCB based on the reported

presence of toluene in ground water Also CA ARNG is considering additional soil gas

sampling and the installation of methane gas detectors in the animal shelter Specific

recommendations pertaining to the Kansas Avenue landfill are as follows

Conduct at least two more rounds of ground water monitoring to verify the

presence of toluene and establish ground water quality history

5-3

GESYSTEM

Consultants Inc
Because of the very shallow depth to ground water Geosystem believes

there is little benefit to installing gas monitoring probes in and around the

landfill Accordingly Geosystem recommends these be deleted from the

scope of any additional investigations Note that the gas monitoring

probes were proposed before the water table was measured at about foot

below grade

Formally notify the County that the Kansas Avenue landfill is located on

its property and make County personnel aware of the potential for the

accumulation of methane gas in County buildings constructed over the

landfill

Proceed with the installation of continuous methane gas detectors in the

animal shelter constructed over the landfill

Through institutional controls prevent the construction of additional

buildings directly over the landfill

Continue to monitor for water quality in Well No paying particular

attention to the possible presence of dissolved toluene

Assuming the additional monitoring does not indicate more significant impact on ground

water corrective action may not be warranted based solely on the low concentrations of

toluene However if the opportunity presents itself in the future it may be prudent to

regrade the landfill area to promote positive drainage prevent ponding and hence

minimize the infiltration of surface water through the disposed wastes If paved the landfill

area would make an ideal parking lot or storage yard provided the potential settlement of

the fill material is taken into consideration

5.1.3 Leaking UST Sites

Releases of petroleum hydrocarbons have been confirmed at numerous former UST sites

within the current boundary of Camp SLO Releases have also been confirmed at at least

one UST site in an area no longer part of Camp SW the former boiler house at the CMC

west facility The hydrocarbons released appear to be exclusively heating oil and diesel

fuel In the very large majority of cases hydrocarbon concentrations in soil beneath the

tanks were below the Countys de facto cleanup level of 100 mg/kg of TPH and the County

5-4

GEYSTEM

ConsultantsInc
does not require any further action At those UST sites where the County has requested

additional work investigations have shown that significant soil contamination is present at

10 UST sites Note that in the subject context significant soil contamination means that

TPH concentrations in soil are substantially higher than 100 mg/kg Of these 10 UST sites

ground water has been impacted at four

Because of the types of contaminants Geosystem believes that the leaking UST sites are not

subject to CERCLA Assuming that the ongoing investigation and possibly remediation

programs wifi continue to conclusion that satisfies the state and local regulatory agencies

Geosystem does not recommend any additional investigations as result of this PA

5.1.4 Hutment Heating Systems

At least one release of heating oil and/or diesel fuel from the heating system at Hutment

Area has been confirmed The release occurred after vehicle damaged an aboveground

valve number of hutments including all of the hutments in Area were demolished in

1993 to clear the space necessary for new barracks complex The associated heating fuel

distribution systems which were reportedly badly corroded were removed in their entirety

during this process The contractor for the new barracks apparently stripped the upper or

feet of soil from the entire construction area generating about 26000 cubic yards of at

least partially contaminated soil This soil was reportedly disced to promote aeration and

bioremediation and has since been stockpiled at Camp SLO awaiting decision regarding

its final disposition

subsurface investigation was conducted at the site of the aboveground release However

no sampling and analysis has been performed in other areas formerly or still occupied by

hutments Also no investigations have been conducted to determine whether ground water

may have been impacted by releases from the hutment heating systems in Area So far

as Geosystem has been able to ascertain SLOCHA was generally satisfied with the remedial

effort but requested additional assessment of residual soil contamination in certain specific

5-5

GEYSTEM

Consultants Inc
areas December 15 1992 In addition the RWQCB January 11 1996 has expressed

concern over the possible impact of the hutment heating systems on ground water quality

Based on the type of contaminant Geosystem believes that the petroleum exclusion will

preclude regulation of the hutment heating oil systems under CERCLA Also DSA and

Geosystem are currently evaluating the nature and extent of subsurface investigations to

determine the possible impact if any of the existing and former hutment heating oil systems

on the subsurface environment It is noted that although the LLNL recommendations

October 16 1996 do not strictly speaking pertain to the hutment heating systems some

type of risk-based corrective action evaluation is very likely to be appropriate Considering

its relatively low toxicity It is very possible that remediation may not be required for the

viscous and nonvolatile heating oil

5.1.5 Unexploded Ordnance

There is very high probability that UXO and the residuals associated with explosives may

be present in large areas within the current and of more concern former boundaries of

Camp SLO Specifically UXO has been discovered on property now owned or occupied

by Cal Poly El Chorro Regional Park SW County Board of Education and the U.S Forest

Service despite these areas having been swept Although the so-called Highway 41 fire

in 1994 caused lot of ordnance to explode it would be optimistic to assume that no more

UXO is present There are few if any restrictions on access to most of the areas in which

UXO has been discovered The residuals of exploded ordnance could include metals and

other hazardous constituents

UXO clearly poses significant threat In addition to CERCLA Geosystem assumes that

unexploded ordnance is regulated by the U.S Army At minimum Geosystem

recommends that the portion of El Chorro Regional Park that has apparently not been

cleared be swept for UXO Geosystem also suggests that land owners and land users be

notified of the possibility that UXO may be encountered within the former boundary of

5-6

GBYSTEM

Consultants Inc
Camp SLO The notification process could include direct mailings and the posting of

warning signs

5.2 POTENTIAL RELEASE SITES

The types of activity conducted at Camp SLO over the last 67 years suggest the potential

for numerous releases of hazardous materials very large majority of the potential release

sites probably involve POLs that would most likely not be subject to regulation under

CERCLA. In many instances site may be suspect merely because of the types of activity

that occurred there in the past In other instances they may be specific indication that

release has actually occurred For discussion purposes potential release sites have been

broadly divided into those at which there is sufficient cause to recommend an SI and those

at which there is not These broad site categories have been termed primary and secondary

potential release site respectively

5.2.1 Primary Potential Release Sites

Geosystem believes that soil quality investigation followed if necessary by ground

water quality investigation is warranted at each of the following potential release sites

Piping associated with the heating systems for the demolished hutments

was reportedly badly corroded resulting in near-surface soil contamination

Because of the identical construction of the heating systems for other

hutment areas it is likely that similar contamination is present in these

areas

Engineering personnel have reported smelling hydrocarbon odors at two

former UST sites the Motor Pool fuel facility Building 888 and the

bulk fuel facility in the engineering yard Buildings 1331 and 1332

sheen was reportedly observed on standing water in an excavation dug at

Building 888 to repair leaking water pipe

PCB-containing transformers were improperly stored outside of

Building 509 Near-surface soils around Building 509 potentially have been

impacted by PCB-containing oil that may have leaked from these

transformers

5-7

GEYSTEM

Consultants Inc
number of pesticides and herbicides have been stored in at least two

different locations in the engineering yard Potential spills related to

pesticide or herbicide storage handling or mixing may have impacted nearsurface soils in these areas Many pesticide and herbicide compounds are

acutely toxic and may be environmentally persistent

In addition to the above the presence of lead projectiles in near-surface soils at the existing

or former small arms firing ranges may be considered hazard While the ranges are still

active including the private range on County property there is little benefit in removing

the projectiles However some type of investigation and/or remedial action may be

necessary in the future

5.2.2 Secondary Potential Release Sites

Secondary potential secondary release sites include those fixed sites at which hazardous

materials are known to have been used stored disposed or otherwise handled for

significant period of time They include among other things all UST sites not previously

investigated all vehicle wash racks all vehicle grease racks and the former Caltrans facility

Clearly there are many other non-fixed or transitory potential release sites Examples

would include locations where vehicles were repaired/lubricated in the field or anywhere

ordnance exploded leaving potentially hazardous residues in soil Because of the absence

of location information the sheer number of such sites and because surface structures have

been constructed over many of them the cost of comprehensive investigation program

would be prohibitively high and unnecessarily disruptive to operations at Camp SLO and

the surrounding areas In the absence of specific information suggesting that release has

occurred Geosystem believes that such program is not warranted This opinion is based

on the following

Based on Camp SLOs long history it is likely that significant releases

would have become apparent either directly during for example

construction/maintenance activities or indirectly by complaints from land

users contamination of wells and the like

5-8

GRYSTEM

Consultants Inc
None of the subsurface investigations conducted at specific release sites

have encountered unexpected contamination that could have originated

from other sources

Geosystem expects that currently unknown release sites will be encountered periodically in

the future especially during demolition activities and subsurface work Such release sites

should be addressed as appropriate as they are encountered

6.0 LIMITATIONS

This PA was conducted in maimer consistent with generally accepted professional

consulting principles and practices No other warranty expressed or implied is made The

scope of the PA was limited to visual observation of surface conditions at the site interviews

with knowledgeable persons and review of readily available records prepared and/or

maintained by CA ARNG various regulatoiy agencies and certain private organizations

No borings or monitoring wells were installed specifically for this PA and no soil water air

or waste samples were analyzed The PA addresses the likelihood of hazardous waste

contamination resulting from past and current land uses to the extent that such land uses

are known It is possible that certain conditions may exist at Camp SW that were not

revealed during the course of this PA Geosystems conclusions and recommendations are

based on the standards and regulations currently in effect Contaminants may be present

at concentrations that do not violate present regulatory standards but may violate future

standards This report has been prepared for use by the State Military Department and the

Division of the State Architect as basis for determining whether additional investigations

and/or remedial response measures are warranted at Camp SLO Any use of this report

GLOSSARY OF TERMS 

anomaly Any item that deviates from the expected subsurface ferrous and 

non-ferrous material at a site (i.e., pipes, power lines, etc.). 

Inhabited structure Permanent or temporary structure, other than military munitionsrelated structures, routinely occupied by one or more persons for 

any portion of a day. 

magnetometer An instrument for measuring the strength of a magnetic field; used 

to detect buried iron and other metal objects. 

military munitions All ammunition products and components produced for or used by 

the armed forces for national defense and security, including 

ammunition products or components under the control of the 

Department of Defense, the Coast Guard, the Department of Energy, 

and the National Guard. The term includes confined gaseous, 

liquid, and solid propellants; explosives, pyrotechnics, chemical and 

riot control agents, smokes, and incendiaries, including bulk 

explosives and chemical warfare agents; chemical munitions, 

rockets, guided and ballistic missiles, bombs, warheads, mortar 

rounds, artillery ammunition, small arms ammunition, grenades, 

mines, torpedoes, depth charges, cluster munitions and dispensers, 

demolition charges; and devices and components thereof. 

munitions and explosives 

of concern (MEC) 

Military munitions that may pose unique explosives safety risks, 

including UXO, discarded military munitions, or munitions 

constituents present in high enough concentrations to pose an 

explosive or other health hazard. 

munitions constituents 

(MC) 

Any materials originating from unexploded ordnance, discarded 

military munitions, or other military munitions, including explosive 

and nonexplosive materials, and emission, degradation, or 

breakdown elements of such ordnance or munitions.

munitions debris Remnants of munitions (e.g., penetrators, projectiles, shell casings, 

links, fins) remaining after munitions use, demilitarization, or 

disposal. 

munitions response Response actions, including investigation, removal actions, and 

remedial actions, to address the explosive safety, human health, or 

environmental risks presented by unexploded ordnance, discarded 

military munitions, or munitions constituents, or to support a 

determination that no removal or remedial action is required.

EXECUTIVE SUMMARY 

ES-1 Camp San Luis Obispo was established in 1928 by California as a 

National Guard Camp and used for infantry division training during World War II and 

signal corps training during the Korean War. Munitions and explosives of concern 

(MEC) activities associated with the former Camp San Luis Obispo (CSLO) included 

small arms training and qualification firing at multiple small arms ranges of various 

types. The facility also supported hand grenade ranges, rifle grenade ranges, and antitank rocket ranges in addition to several courses and ranges that authorized the use of 

multiple types of weapons. There were originally 27 World War II era ranges and 

thirteen training areas. The ranges and training areas were occasionally used for 

combined arms live fire maneuvers. A site inspection (SI), documented in this report, 

was conducted to determine whether munitions response sites (MRSs) identified within 

CSLO warrant subsequent characterization as part of a remedial investigation/feasibility 

study (RI/FS) or no Department of Defense (DoD) action indicated (NDAI). The SI was 

performed to evaluate evidence for the presence of munitions and explosives of concern 

(MEC) and munitions constituents (MC) within each of the five MRSs. To accomplish 

this objective, qualitative reconnaissance (QR) and MC sampling were performed. 

ES-2 The technical project planning (TPP) process identified that, in addition to 

QR, the collection of eleven surface soil samples and two groundwater samples (plus 

associated quality assurance/quality control samples) would be sufficient to meet the SI 

project objectives. 

ES-3 The SI evaluation included the conduct of approximately 35 miles of 

pedestrian QR as well as the collection of twelve surface soil samples and two 

groundwater samples. Although only eleven surface soil samples were planned, an 

additional discretionary sample was collected by the Site Visit Team (SVT) based on 

field observations. All but two surface soil samples (ambient) were collected from areas 

that, according to the TPP Team consensus, represented the highest likelihood for the 

presence of MEC or MC contamination. 

ES-4 TestAmerica (formerly Severn Trent Laboratories) located in Arvada, 

Colorado analyzed the surface soil samples for explosives and total metals. The 

groundwater samples were analyzed by TestAmerica for explosives, perchlorate, and 

metals. Metals were not analyzed for in the groundwater sample collected near the active 

firing range due to the potential for non-DoD source metals. Two surface soil samples 

also included analysis for white phosphorus which was completed by DataChem in Salt 

Lake City, Utah. The analytical results from the surface soil sampling were evaluated for 

human health concerns using the U.S. Environmental Protection Agency (USEPA)

Region 9 Residential Preliminary Remediation Goals (PRGs) and California-Modified 

USEPA Region 9 PRGs, as agreed upon during the TPP Meeting. USEPA ecological soil 

screening levels (SSLs) were used as comparison criteria for the Screening Level 

Ecological Risk Assessment (SLERA). The analytical results for the groundwater 

samples were evaluated using the DoD’s policy level of concern for perchlorate at 24 

micrograms per liter (μg/L), as well as California Department of Health Services 

notification level of 6.0 μg/L. Perchlorate was detected in both of the groundwater 

samples; however, well below the established screening criteria. No explosive 

compounds were detected in any of the surface soil samples collected from within any of 

the five MRSs. White phosphorus was also not detected in the surface soil samples 

collected at the site. No metals were detected at levels exceeding human health screening 

criteria. Copper detected in surface soil at MRS 01/MRS 02, and antimony and copper 

detected in surface soil collected from MRS 05, are at concentrations that would not pose 

an unacceptable potential for risk to the health of ecological receptors. 

ES-5 One MEC item was observed in an area of potential concern identified in 

the original Archives Search Report but not retained as an MRS as documented in the 

2004 ASR Supplement. The area was designated as the Rifle Grenade Range (1952). 

QR and MC sampling was conducted within this non-MRS area based on request from 

the California Department of Toxic Substances and Control (and subsequent concurrence 

by the TPP Team. Several munitions-related features observed within MRS 02, MRS 04, 

MRS 05, and the Rifle Grenade Range (1952) non-MRS included berms, an armored 

tank, grenade foxholes, grenade throwing stations, and a possible crater.

included general small arms, fragmentation hand grenades (MK II), anti-tank rifle 

grenades (M9A1), practice hand grenades (M62), 60mm mortars, 81mm mortars, 3.5-

inch rockets, high explosive 105mm and 155 mm shells, 2.36-inch rockets and boosters 

(M20). Both MEC and MD was identified at the Rifle Grenade Range (1952) nonMRS. Munitions debris (indicative of potential presence of MEC) was also observed 

throughout MRS 05. In addition, MEC and MD has been reported in MRS 05 over the 

years. MEC was most recently reported at MRS 05 in January/February 2007 during 

an informal field visit by DTSC. No MEC or MD was identified during the SI at MRS 

01 or MRS 02; however, MD has been reported at both of these MRSs in the past. No 

MEC or MD was identified during the SI or any other prior site evaluation at MRS 03 

or MRS 04. 

ES-7 It is recommended that MRS 03 and 04 at the CSLO site each proceed to 

NDAI based on the absence of MEC and MC during the SI and prior site visits. 

Although no MEC or MD was observed during the SI, MRS 01 and 02 are recommended 

to proceed to RI/FS based on circumstantial documentation of a limited historical 

removal action and reports of continued MD presence. No MC above screening levels 

were detected; therefore, additional sampling during the RI/FS is not recommended. 

ES-8 It is recommended that MRS 05 proceed to RI/FS due to the presence of 

both MEC and MC. Further MC sampling is recommended to properly characterize the 

MRS. It is also recommended that all media be investigated further in the RI/FS.

CHAPTER 1 

INTRODUCTION 

1.1 BACKGROUND 

1.1.1 Parsons Corporation (Parsons) received Contract No. W912DY-04-D0005, Task Order No. 0009, from the United States Army Corps of Engineers (USACE), 

Engineering and Support Center, Huntsville (USAESCH) to perform a Site Inspection 

(SI) at the former Camp San Luis Obispo Formerly (CSLO) Used Defense Site (FUDS) 

located in San Luis Obispo, California. The former Camp San Luis Obispo was 

established in 1928 by California as the National Guard Camp. Designated originally as 

Camp Merriam, CSLO was originally established on 5,800 acres. Additional lands were 

annexed in the early 1940s bringing the final total acreage of the facility to 14,959.16 

acres. During World War II, Camp San Luis Obispo was used by the U.S. Army from 

1943 to 1946 for infantry division training. The types of training supported at CSLO 

included artillery, small arms, mortar, rocket, and grenade training. According to the 

Historical Records Review (HRR), there were a total 27 ranges and thirteen other training 

areas located within Camp San Luis Obispo during World War II. During the Korean 

War, the Southwest Signal Corps Training Center was the primary unit assigned to the 

Camp. The ranges on the installation in 1952 were associated with individual and squad 

weapons (small arms, hand and rifle grenades, and anti-tank rockets). During this time, 

training exercises were primarily for replacement personnel rather than unit training, and 

focused on individual weapons (rifles and hand grenades). Construction at the Camp 

included typical dwellings, garages, latrines, target houses, repair shops, and 

miscellaneous range structures. Property acquisitions and reacquisitions in support of 

various missions into the early 1960s resulted in a comprehensive FUDS-eligible acreage 

totaling only 2,101 acres, as depicted on Figure 1.1. As such, the former Camp San Luis 

Obispo has been assigned FUDS Project #J09CA203105. 

1.1.2 For the purposes of this SI 

Report, five parcels comprising former training 

areas have been identified as Munitions 

Response Sites (MRSs) for further evaluation 

during the SI. Figure 1.1 and 1.2 depict the 

MRS and FUDS boundaries for the CSLO. The 

coordinates for the center point of each MRS 

are listed in Table 1.1. The coordinates are in 

meters [Universal Transverse Mercator (UTM) 

Zone 11 North American Datum (NAD) 83]. Figure 1.3 depicts the MRS designations.

1.2 PROJECT OBJECTIVES 

1.2.1 The Department of Defense (DoD) has established the Military Munitions 

Response Program (MMRP) to address DoD sites suspected of containing munitions and 

explosives of concern (MEC) or munitions constituents (MC). Under the MMRP, the 

USACE is conducting environmental response activities at FUDS for the Army, DoD’s 

Executive Agent for the FUDS program. 

1.2.2 Pursuant to USACE’s Engineer Regulation (ER) 200-3-1 (USACE, 2004) 

and the Management Guidance for the Defense Environmental Response Program 

(DERP) (Office of the Deputy Under Secretary of Defense [Installations and 

Environment], September 2001), USACE is conducting FUDS response activities in 

accordance with the DERP statute (10 United States Code [USC] 2701 et seq.), the 

Comprehensive Environmental Response, Compensation, and Liability Act of 1980 

(CERCLA) (42 USC §9620), Executive Orders 12580 and 13016, and the National Oil 

and Hazardous Substances Pollution Contingency Plan (NCP) (40 Code of Federal 

Regulations [CFR] Part 300). As such, USACE is conducting remedial SIs, as set forth 

in the NCP, to evaluate hazardous substance releases or threatened releases from eligible 

FUDS and eligible MRSs within FUDS. 

1.2.3 While not all MEC/MC constitute CERCLA hazardous substances, 

pollutants or contaminants, the DERP statute provides DoD the authority to respond to 

releases of MEC/MC, and DoD policy states that such responses shall be conducted in 

accordance with CERCLA and the NCP. 

1.2.4 The primary objective of the MMRP SI is to determine whether a FUDS 

project warrants further response action under CERCLA or not. The SI collects a 
DRAFT FINAL 

1-3 

CHP. 1.DOC REV. 1 

CONTRACT W912DY-04-D-0005, DELIVERY ORDER 0009 8/14/2007 

sufficient amount of information necessary to make this determination. Additionally, it 

(i) determines the potential need for a removal action (ii) collects or develops additional 

data, as appropriate, for Hazard Ranking System (HRS) scoring by the U.S. 

Environmental Protection Agency (USEPA); and (iii) collects data, as appropriate, to 

characterize the release for initiation of the RI/FS. An additional objective of the MMRP 

SI is to collect the additional data necessary to complete the Munitions Response Site 

Prioritization Protocol (MRSPP). 

1.2.5 The SI was performed as a result of the potential for MEC/MC 

contamination at the five MRSs. All work adhered to the DERP for FUDS and relevant 

U.S. Army regulations and guidance for MMRP programs. As specified in the task order, 

this report is prepared to summarize the SI sampling events for the Camp San Luis 

Obispo site and presents an accounting of the MEC/MC contamination identified on-site. 

1.3 PROJECT SCOPE 

1.3.1 During the 1993 field visit in support of the ASR the team observed 

munitions debris (MD) limited only to a single expended hand grenade fuze. There were 

no MEC observations or additional observations of MD (CEMVR, 1994). The ASR 

documented numerous historical accounts of MEC and MD found over the years 

(detailed in Chapter 2). The ASR team assessed seven areas of potential concern within 

the former Camp San Luis Obispo site (inclusive of the five MRSs). Table 1.2 below 

summarizes the ASR conclusions.

1.3.2 The findings of the ASR are recorded in Subchapter 2.5 of this SI Report. 

Along with historical reports of MEC and MD (USACE, 1994), there has also been a 

recent report of MEC during the informal site visit by Department of Toxic Substances 

Control (DTSC) in January/February 2007. As a result, the Technical Project Planning 

(TPP) Project Team concurred that the SI would proceed in a manner to support an RI/FS 

for the MRSs. The SI for CSLO evaluated the potential presence of MEC (to include 

unfired small arms) and MC in each MRS as well as in a non-MRS area of potential 

concern known as the former Rifle Grenade Range (1952) located south of MRS 04. The 

rationale for evaluating the Rifle Grenade Range (1952) was based on concerns raised by 

individuals of the TPP Project Team. Additionally, the informal site visit conducted by 

DTSC observed some rifle grenade debris (MD) in this former range. 

1.3.3 The USACE Los Angeles District (CESPL) facilitated a TPP Meeting on 

7 February 2006 that included representatives of CESPL; Parsons; DTSC; California 

Polytechnic State University (Cal Poly); CDF&G; Los Padres National Forest; San Luis 

Obispo (SLO) County Parks; and SLO County Office of Education. The TPP Team 

discussed and refined the initial Technical Approach (limited to the Korean War era use 

of the facility) during the course of the TPP Meeting yielding a Final TPP Memorandum 

(Parsons, 2006b). The TPP Team agreed that additional data needed to be obtained 

covering the use of the site during World War II. The Technical Approach was further 

discussed and refined on a conference call with the TPP Team on 13 September 2006, 

which included the additional World War II era data obtained. Unanimous TPP Team 

concurrence with the revised Technical Approach presented in the Final TPP 

Memorandum issued 12 October 2006 was achieved (Appendix B) including the 

locations of the 11 surface soil samples and two groundwater samples (with associated

duplicate samples), sampling methods, and laboratory analyses for explosives, metals 

constituents, perchlorate, and white phosphorus. The TPP Project Team concurred that 

human health comparison criterion for surface soil sample results would be the USEPA 

Region 9 Residential Preliminary Remediation Goals (PRGs) and California Modified 

USEPA Region 9 PRGs. The screening criteria for the water samples, the TPP Project 

Team agreed would be the DoD’s policy level of concern for perchlorate at 24.0 

micrograms/liter (μg/L), California Department of Health Services notification level for 

perchlorate of 6 μg/L, as well as USEPA Region 9 Human Health Screening Values for 

Tap Water PRGs. Ecological screening levels were developed and reviewed by the TPP 

Project Team as part of the development of the SS-WP Addendum. 

1.3.4 The TPP Project Team concurred that the SI data collection efforts would 

focus on screening for MC contamination in surface soil and groundwater. A total of 11 

surface soil samples and two groundwater samples; with an optional third groundwater 

sample if an additional groundwater source could be located, along with the appropriate 

Quality Assurance/Quality Control (QA/QC) samples and field duplicates were planned 

for CSLO at the five associated MRSs. One surface soil sample was collected from each 

Grenade Court Range #25 MRS 01 and Grenade Court Range #26 MRS 02; one surface 

soil sample was collected from Grenade Court Range #27 MRS 03; one surface soil 

sample was collected from Grenade Court Range #17 MRS 04; five surface soil samples 

were collected in Range Complex MRS 05; and one surface soil sample was collected in 

the non-MRS area of potential concern designated as Rifle Grenade Range (1952). An 

additional discretionary surface soil sample was collected in Range Complex MRS 05 (as 

provided in the Site Specific Work Plan [SS-WP] Addendum) based on field 

observations. Two surface soil samples were collected in undeveloped areas in the 

extreme eastern portion and the southwest portion of the CSLO to provide “ambient” 

data. 

1.3.5 The primary project planning documents used to perform the SI include 

the SS-WP Addendum for the Camp San Luis Obispo (Parsons, 2007), the USACE South 

Pacific Division Range Support Center (SPD RSC) Programmatic Work Plan (PWP) 

(Parsons, 2005), the Programmatic Sampling and Analysis Plan (PSAP) (USACE, 2005), 

and the PSAP Addendum (Parsons, 2006a). The performance work statement for this 

project is included in Appendix A.

1.0 INTRODUCTION 

1.1 PROJECT AUTHORIZATION 

This work plan (WP) has been prepared in compliance with the Performance Work Statement 

(PWS) identified in Contract W912PL-09-D-0005, Task Order 0003, with the U.S. Army 

Corps of Engineers (USACE), Los Angeles District. USACE, Los Angeles District, has 

administrative control and is managing all aspects of this project. A copy of the PWS dated 

07 January 2010 has been provided as Appendix A of this WP. The work required under this 

PWS is authorized under the Defense Environmental Restoration Program (DERP) for 

Formerly Used Defense Sites (FUDS) J09CA203105 at Camp San Luis Obispo (CSLO), San 

Luis Obispo, California. 

Bristol Environmental Remediation Services, LLC (Bristol), under this contract, was tasked to 

execute a Remedial Investigation/Feasibility Study (RI/FS) to define target areas at Munitions 

Response Sites (MRS): MRS-01, MRS-02, and MRS-05 at CSLO. Bristol will furnish all 

labor, management, supervision, tools, materials, equipment, mobilization, demobilization, 

and transportation required to accomplish the RI/FS tasks. Bristol will provide competent, 

trained, and qualified personnel as necessary to meet project objectives. 

This project WP has been prepared to summarize the activities performed in completion of 

field work from the RI tasks: 

Create a project WP, including a Sampling and Analysis Plan (SAP) and Uniform 

Federal Policy (UFP) Quality Assurance Project Plan (QAPP) in accordance with 

Department of Defense (DoD) Data Item Description (DID) Military Munitions 

Response Program (MMRP)-09-001, and additional guidance specified in the PWS; 

Perform geophysical survey at three MRSs; 

Perform reacquisition and subsurface investigation of up to 4,399 targets on 

approximately 2,549 acres. The RI will consist of Digital Geophysical Mapping 

(DGM) of the area, target definition, target re-acquisition, intrusive investigation, and 

removal; 

Properly dispose of all unexploded ordnance (UXO)/munitions and explosives of 

concern (MEC) and demilitarized military munitions (DMM) encountered during the 

investigation; 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-2 FINAL 

Conduct background metals survey and munitions constituent (MC) sampling as 

specified in the Data Quality Objectives (DQOs); 

Prepare and manage project Geographic Information System (GIS) in accordance with 

current CEHNC-CX-MM-DID; and 

Create a RI/FS report. 

1.2 IDENTIFICATION OF GUIDANCE, REGULATIONS, OR OTHER POLICY

The DoD established the MMRP to investigate DoD sites suspected of containing MEC or 

MC. Under the MMRP, the USACE is conducting environmental response activities at 

FUDS for the Army, the DoD’s Executive branch for the FUDS Program. 

The purpose of this RI/FS is to address UXO, DMM, and MC, adequately characterize target 

areas associated with three MRS, and allow for the evaluation of remedial alternatives. This 

information is to be used to prepare and obtain stakeholder concurrence on a Decision 

Document (DD). 

At the conclusion of the RI/FS, Bristol, in coordination with the USACE, will develop an 

RI/FS report that documents the results of the investigation, evaluate the findings of those 

activities in association with the proposed MEC alternatives, and recommend further remedial 

actions, a risk management process, or No DoD Actions Indicated (NDAI) for the areas 

investigated. The format of the RI/FS report will be consistent with USACE guidance 

documents, including the following: USACE Huntsville (Environmental and Munitions 

Center for Expertise) DID MMRP-09-001, USACE Engineering Manual (EM) 1110-1-4009, 

and EM 385-1-1 as appropriate.

1.2.1 Assessment of Applicable or Relevant and Appropriate Requirements 

This section presents an initial assessment of Applicable or Relevant and Appropriate 

Requirements (ARARs) and To Be Considered (TBC) guidance for the RI/FS. Throughout 

the investigation processes at CSLO, the ARARs/TBC lists will be updated if additional 

ARARs and guidance are identified. Section 121 of the Comprehensive Environmental 

Response, Compensation, and Liability Act (CERCLA) requires that site cleanups comply 

with federal ARARs, or state ARARs in cases where these requirements are more stringent 

than federal requirements. ARARs and TBC guidance are derived from both federal and state 

laws and guidance. Under CERCLA Section 121(d) (2), the federal ARARs/TBCs for 

remedial action could include requirements under any of the federal environmental laws 

(i.e., Clean Air Act [CAA], Clean Water Act [CWA], and Safe Drinking Water Act 
Work Plan Remedial Investigation/Feasibility Study

[SDWA]). State ARARs (e.g., California Human Health Screening Levels [CHHSL]) include 

promulgated requirements under state environmental or facility siting laws that are more 

stringent than federal ARARs and that have been identified in a timely manner, according to 

40 Code of Federal Regulations (CFR) Part 300.400(g)(4). A requirement may be either 

“applicable” or “relevant and appropriate,” or “TBC.”

Applicable requirements are defined as those cleanup or control standards, or other 

substantive environmental protection requirements, criteria, or limitations promulgated under 

federal or state laws. Applicable requirements are identified on a site-specific basis by 

determining whether the jurisdictional prerequisites of a requirement fully address the 

circumstances at the site or the proposed remedial activity. All pertinent jurisdictional 

prerequisites must be met for the requirement to be applicable. These jurisdictional 

prerequisites are as follows: 

The party must be subject to the law; 

The substances or activities must fall under the authority of the law; 

The law must be in effect at the time the activities occur; and 

The statute or regulation requires, limits, or protects the types of activities. 

A requirement is applicable if the specific terms (or jurisdictional prerequisites) of the statute 

or regulation directly address the circumstances at the site. 

If not applicable, a requirement may be relevant and appropriate if circumstances at the site 

are sufficiently similar to the problems or situations regulated by the requirement. “Relevant 

and appropriate” refers to those cleanup standards, or other substantive environmental 

protection requirements, criteria, or limitations promulgated under federal or state law that, 

while not necessarily applicable, address problems or situations sufficiently similar to those 

encountered at the CERCLA site, and whose use is well suited to the particular site. The 

relevance and appropriateness of a requirement can be judged by comparing a number of 

factors, including the characteristics of the remedial action, the items in question, or the 

physical circumstances of the site, with those addressed in the requirement. If there is 

sufficient similarity between the requirements and circumstances at the site, determination of 

the requirement as relevant and appropriate may be made.

August 2011 1-5 FINAL 

Determining whether a requirement is both relevant and appropriate is a two-step process. 

First, to determine relevance, a comparison is made between the response action, location, or 

chemicals covered by the requirement and related conditions at the site, release, or potential 

remedy. A requirement is relevant if it generally pertains to these conditions. Second, to 

determine whether the requirement is appropriate, the comparison is further refined by 

focusing on the nature of the items, the characteristics of the site, the circumstances of the 

release, and the proposed response action. The requirement is appropriate if based on such 

comparison, its use is well suited to the particular site. The facility must comply with 

requirements that are determined to be both relevant and appropriate. 

In addition to ARARs, non-promulgated advisories or guidance referred to as TBC materials 

may also apply to the conditions found at a site. TBCs are not legally binding. There are 

certain circumstances under which ARARs may be waived. CERCLA Section 121(d) allows 

the selection of alternatives that will not attain ARAR status if any of six conditions for a 

waiver of ARARs exists. However, the selected alternative must be protective even if an 

ARAR is waived. Only five of the conditions for a waiver may apply to a DoD site. The 

conditions for a waiver are as follows: 

The clearance action selected is only part of a total response action that will attain 

such level or standard of control when completed; 

Compliance with such a requirement at a particular site will result in greater hazard to 

human safety and the environment (i.e., worker safety) than alternative options; 

Compliance is technically impracticable from an engineering perspective; 

The clearance action selected will result in a standard of performance that is 

equivalent to an applicable requirement through the use of another method or 

approach; 

A state requirement has not been equitably applied in similar circumstances on other 

clearance actions within the state; and 

A fund-financed clearance action does not provide a balance between available monies 

and the need for protection of public safety and the environment at sites where the 

need is more immediate (not applicable to DOD sites). 

ARARs that govern actions at CERCLA sites fall into three broad categories based on the 

chemical contaminants present, site characteristics, and alternatives proposed for cleanup.

These three categories (chemical-specific, location-specific, and action-specific) are described 

in the following subsections. 

1.2.1.1 Chemical-Specific ARARs

Chemical-specific ARARs include those environmental laws and regulations that regulate the 

release to the environment of materials with certain chemical or physical characteristics or 

that contain specified chemical compounds. There are no chemical-specific ARARs for 

MEC; however, chemical-specific ARARs associated with MC were developed. These 

requirements generally set health- or risk-based concentration limits or discharge limits for 

specific hazardous substances by media. Chemical-specific ARARs are triggered by the 

specific chemical contaminants found at a particular site. USEPA currently considers 

standards developed under the Resource Conservation and Recovery Act (RCRA), the 

SDWA, the CWA, and federal Ambient Water Quality Criteria for the protection of aquatic 

life as potential ARARs. A more stringent standard, requirement, criterion, or limitation 

promulgated pursuant to a state environmental statute is also a potential ARAR.

1.2.1.2 Location-Specific ARARs

Location-specific ARARs govern activities in certain environmentally sensitive areas. These 

requirements are triggered by the particular location and the proposed activity at the site. 

Actions may be restricted or precluded based on proximity to wetland or floodplains or the 

presence of natural or cultural resources. Discussions of ARARs applicable to threatened and 

endangered species, migratory birds, wetlands, and cultural resources are further discussed 

specific to the MRSs discussed in Sections 6.2 and 6.3.

1.2.1.3 Action-Specific ARARs

Action-specific ARARs are restrictions that define acceptable treatment and disposal 

procedures for hazardous substances. These ARARs generally set performance, design, or 

other similar action-specific controls or restrictions on particular kinds of activities. An 

example might be a state Air Quality Management Authority that sets limitations on fugitive 

dust generated during grading and excavation activities during a clearance action.

1.4 PROJECT LOCATION

CSLO is located along Highway 1, approximately 8 miles east of the Pacific Ocean (at Morro 

Bay) and approximately 5 miles northwest of San Luis Obispo, California, between the cities 

of San Luis Obispo and Morro Bay on the western slopes of the Santa Lucia Range. CSLO is 

located in San Luis Obispo County, as shown in Appendix B, Site Location Map. The former 

CSLO occupied approximately 14,959 acres. 

Three MRSs, identified during the Archive Search Report (ASR) and Site Inspection (SI) 

processes will be investigated during the RI/FS. The CSLO MRSs encompass approximately 

2,549 acres (approximately 4 square miles) of rolling hills and canyons. These sites are MRS01 (formerly Grenade Court, Range #25), MRS-02 (formerly Grenade Court, Range #26) and 

MRS-05 (formerly a Range Complex). MRS-05 is 2,523 acres, and MRS-01 and MRS-02 

combined are 26 acres. The MRS locations are shown in Appendix B, MRS Location Map. 

1.5 SITE DESCRIPTION

The following sections include site background information, such as topography, climate, 

vegetation, and geology gathered from state and federal resources, as well as observations 

made during site visits of the area, previous investigations, and the 1992 and 2010 TCRA at 

CSLO. 

1.5.1 Topography 

The CSLO site consists mainly of rolling hills and canyons classified as grassland, wooded 

grassland, woodland, or brush. A major portion of the site is identified as grassland and is 

used primarily for agricultural purposes (i.e., grazing). Los Padres National Forest is located 

at the north-northeastern portion of the site. During the hot and dry summer and fall months, 

the intermittent areas of brush occurring throughout the site become a critical fire hazard. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-15 FINAL 

Appendix B, Site Topography, shows the varied site terrain. Land use in general supports the 

agricultural (grazing), recreational, and educational/institutional uses. 

1.5.2 Vegetation 

Vegetation type communities include central oak woodland, annual grassland, mixed 

evergreen woodland coastal sage scrub, and central maritime chaparral. The coastal sage 

scrub vegetation type of California exists along the coast from about San Francisco down 

through about San Diego and inland as far as Riverside in southern California. Lichens and 

blue-green algae are important components of the coastal sage scrub plant community. In 

sandy soils near the coast, these plants stabilize the loose soils and capture nitrogen for the 

plant community. These plants, along with naturally non-compacted, fluffy soils (created by 

the plants and microorganisms in cooperation), are indicators of a healthy site (Parsons, 

2007). 

Under the term oak woodland are three variations observed in the vicinity of CSLO: oak 

woodlands, where the oaks and pines were fairly close together mixed in with tall and short 

shrubs, and openings of wildflowers, forbs and few grasses; oak savanna, where the trees are 

a good distance apart, mostly few to no shrubs, and between is mostly forbs with little grass. 

The woods were thickets in some places. There are oak forests where the oaks and pines are 

touching and there are several layers of understory, from tall shrubs to short shrubs to 

perennial and annual forbs, with a very small amount of grass (USACE, 2007). 

1.5.3 Climate 

The weather at CSLO is generally pleasant and considered Mediterranean. Within the 

foothills of the former camp, the winters are somewhat cooler and wetter, and the summers 

are warmer and drier. Average rainfall of 16 inches generally occurs between November and 

March. As the clouds move inland from the coastline and rise over the mountains, rainfall 

totals can average from 30 to 45 inches along the ridge-tops. The wind generally comes in 

from the west-southwest and blows to the north-northwest (CEMVR, 1994).

August 2011 1-16 FINAL 

1.5.4 Soil 

The underlying bedrock within the CSLO site area is intensely folded, fractured, and faulted. 

The site is underlain by a mixture of metamorphic, igneous, and sedimentary rocks less than 

200 million years old. Scattered throughout the site are areas of fluvial sediments overlaying 

metamorphosed material known as Franciscan mélange. These areas are intruded by plugs of 

volcanic material that comprise a chain of former volcanoes extending from the southwest 

portion of the site to the coast. Due to its proximity to the tectonic interaction of the North 

American and Pacific crustal plates, the area is seismically active (CEMVR, 1994). 

A large portion of the site consists of rolling hills and mountains with three categories of soils 

occurring within: alluvial plains and fans; terrace soils; and hill/mountain soils. Occurring 

mainly adjacent to stream channels are the soils associated with the alluvial plains and fans. 

Near the main CSLO, the slope is nearly level to moderately sloping and the elevation ranges 

from 300 to 1,500 feet. The surface layer is coarse sandy loam to shaley loam. The 

hill/mountain soils are strongly sloping to very steep. The elevation ranges from 600 to 3,400 

feet. Soil types are shown in Appendix B, Soil Types. 

1.5.5 Site Geology 

CSLO lies among the intermontane basins in the coastal mountains of California. These 

basins, formed as a result of folding and faulting, are depressions or structural troughs that 

parallel the coastline. These folds and faults primarily trend northwestward and result from 

the deformation of older rocks from the intense pressures of colliding continental plates. The 

rocks underlying the basins and form the surrounding mountains are primarily marine 

sediments and igneous and metamorphic rocks, all of Mesozoic age but locally include rocks 

of Cenozoic age (U.S. Geological Survey [USGS], 1995). 

The basins are partially filled with unconsolidated and semi-consolidated marine sedimentary 

rocks deposited during periodic encroachment of the sea and with unconsolidated continental 

deposits that consists of sedimentary rock and weathered igneous material transported into the 

basins primarily by mountain streams. These continental deposits and marine sediments are 

tens of thousands of feet thick in some basins. In most basins, almost all of the permeable

material consists of unconsolidated continental deposits (primarily sand and gravel) (USGS, 

1995).

1.5.6 Surface water/Groundwater 

The regional direction of groundwater flow in Chorro Valley follows the topography in 

general. Near Chorro Creek and its tributaries, the direction of flow is generally downstream 

(Carollo Engineers, 2003). 

Both the city of San Luis Obispo and San Luis Obispo County extract groundwater from the 

San Luis Obispo Valley Groundwater Basin, which underlies the San Luis and Edna Valleys 

and is bounded on the southwest by the San Luis Range, on the northeast by the Santa Lucia 

Range, and on all other sides by contact with impermeable Miocene and Franciscan Group 

rocks. The southeastern part of the valley is drained by tributaries of Pismo and Davenport 

Creeks. The northwestern part of the valley is drained by San Luis Obispo, Stenner, and 

Prefumo Creeks (State of California, 2004). 

Groundwater is found in Pleistocene to Holocene age terrestrial deposits. Holocene age 

alluvium consists of unconsolidated gravel, sand, silt, and clay of fluvial origin, reaching a 

maximum thickness of approximately 50 feet. In the area of the basin that underlies the San 

Luis Obispo Creek watershed, the valley floor is covered with this alluvium and is the main 

source of groundwater. Groundwater wells in this region generally yield from 20 to 300 

gallons per minute (gpm). The Pleistocene age alluvium terrace deposits are as thick as 50 

feet; wells completed in these deposits yield about 20 gpm (State of California, 2004). The 

California Regional Water Quality Control Board reports that the depths of the 

municipal/irrigation wells range to 210 feet below ground surface (bgs) and average of 90 feet 

bgs. The depths of the domestic wells are unknown (State of California, 2004). 

The Edna fault is the main geologic structure in the basin, but it does not appear to affect the 

quality or movement of groundwater. Basin recharge is from applied irrigation water, streamflow, and infiltration of precipitation on the valley (State of California, 2004). 

The CSLO site is located in the Mesozoic Franciscan Formation, which includes ultramafic 

rocks not generally recognized as water-bearing formations. The main drainage at the site is 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-18 FINAL 

Chorro Creek. Surface drainage is generally to the west. The Chorro Creek and its tributaries 

are intermittent and flow only when precipitation is sufficient. The Los Osos, Chorro, 

Walters, Chumash, Pennington and Morro Creeks provide drainage to the Los Osos Valley 

drainage basin, where water bearing formations are found. Groundwater in the Los Osos 

Valley is found at depths from 10 to 50 feet bgs. The water bearing zone is estimated to 

extend to a depth of 200 feet bgs and is drained by Chorro Creek and Los Osos Creek. 

Sediment debris is transported by these creeks into Morro Bay during hydrologic events 

(CEMVR, 1994). 

The Surface Water Map is included in Appendix B. 

1.6 SITE HISTORY

CSLO was established in 1928 by the state of California as a National Guard Camp. 

Identified at that time as Camp Merriam, it originally consisted of 5,800 acres. Additional 

lands were added in the early 1940s until the total acreage reached 14,959. During World 

War II, CSLO was used by the U.S. Army from 1943 to 1946 for infantry division training. 

Uses of the camp included artillery, small arms ranges, mortar, rocket, and grenade practice 

ranges. According to the Preliminary Historical Records Review (HRR), a total of 27 ranges 

and 13 training areas were located on CSLO during World War II. 

Following the end of World War II, a small portion of the former camp land was returned to 

its former private owners. The U.S. Army was making arrangements to relinquish the rest of 

CSLO to the state of California and other government agencies when the conflict in Korea 

started in 1950. The camp was reactivated at that time. 

The U.S. Army used the former camp during the Korean War from 1951 through 1953 where 

the Southwest Signal Center was established for the purpose of signal corps training. The 

HRR identified 18 ranges and 16 training areas present at CSLO during the Korean War. A

limited number of these ranges and training areas were used previously during World War II. 

Following the Korean War, the camp was maintained in inactive status until it was 

relinquished by the U.S. Army in the 1960s and 1970s. Approximately 4,685 acres were 

relinquished to the General Services Administration (GSA) in 1965. GSA then transferred the 

property to other agencies and individuals beginning in the late 1960s through the 1980s; 
Work Plan Remedial Investigation/Feasibility Study

most of which was transferred for educational purposes (e.g., California Polytechnic State 

University (Cal Poly) and Cuesta College, etc.). A large portion of CSLO (the original 5,880 

acres) has been retained by the California National Guard (CNG) and is not part of the FUDS 

program. 

1.7 CURRENT AND PROJECTED LAND USE

The area is served by a state highway (State Highway 1 that intersects the site) and numerous 

secondary roads. Occupied structures located within the MRSs include support facilities 

associated with California Department of Fish and Game (CDFG), Cal Poly Agricultural 

School, and Cuesta College. The primary range complex (MRS-05) is located north of 

Highway 1 and west of El Chorro Regional Park. The remaining MRSs (MRS-01 and MRS02) are located in the general vicinity and parallel to and north of State Highway 1 and occupy 

areas used as recreational facilities within El Chorro Regional Park. Further development is 

planned in the Botanical Gardens located adjacent to MRS-01 and MRS-02. 

The CSLO site is currently owned by several different entities (with one exception, all are 

federal, state, or local government owners) and current land use is primarily for educational 

and agricultural purposes. The majority of the site consists of mountains and canyons. The 

FUDS portion of CSLO has been redeveloped and used by the following organizations: 

Cal Poly for use by its agricultural school; 

San Luis Obispo Public School District; 

El Chorro Regional Park of San Luis Obispo County; and 

CDFG, used primarily for educational purposes and recreation firearms range. 

According to David Ragsdale and Mike Hall, both from Cal Poly, because portions of MRS04 are currently a public shooting range, there can be as many as 100 visitors daily to the site 

(Parsons, 2007). The range also hosts 500 to 600 people at special events that include the 

Annual John Wayne Shoot-Out and the National Championships. Portions of MRS-05 

(primarily the 3.5” Rocket Range #15) are used for hosting campers and recreational vehicles 

during these special events that occur five to seven times a year; Mr. Ragsdale considered that 

there are probably 100 to 250 campers for each of these events. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-20 FINAL 

The land use under these various government entities would not have contributed MC or 

MEC-related contamination, although the current recreational firearms range operated by 

CDFG is in the general vicinity of MRS-04 and the area of potential concern Rifle Grenade 

Range. According to the ASR, the military also used the range for small arms training. 

Future land use is anticipated to remain the same and development for similar purposes will 

likely continue. There is a potential for residential development in the area, especially with 

the planned water project (Nacimiento Water Project), currently in the development stage to 

deliver supplemental water from Lake Nacimiento to San Luis Obispo County, including the 

city of San Luis Obispo (Parsons, 2007). 

Access to the site is restricted and inaccessible to the general public in some areas, while other 

areas are unrestricted and accessible by foot as well as by several secondary roads including, 

but not limited to, Gilardi Road, Pennington Creek Road, Watson Drive, Dairy Creek Road, 

and Highway 1 (Cabrillo Highway). Warning signs regarding the potential presence of 

ordnance are posted in a few areas just outside of El Chorro Regional Park (north of the park 

and associated with fenced areas). 

Potential ecological receptors are documented in Section 6, Environmental Protection Plan. 

Four special status listed taxa are present or may be present on the MRS-05 project site, which 

include those found in Table 6-4. Three of the species are present or may be present on the 

site, including the Chorro Creek bog thistle (Cirsium fontinale), California red-legged frog 

(Rana draytonii), and the southern steelhead (Oncorhynchus mykiss). 

1.8 PREVIOUS INVESTIGATION OF THE SITE

MEC activities associated with the former CSLO include small arms training and 

qualification firing at multiple small arms ranges of various types. The facility also supported 

hand grenade ranges, rifle grenade ranges, and antitank rocket ranges in addition to several 

courses and ranges that authorized the use of multiple types of weapons. The original 27 

World War II era ranges and 13 training areas were occasionally used for combined arms live 

fire maneuvers (Historical Range Map, Appendix B). An historical document review for the 

CSLO revealed the following investigations have been conducted to date: 

Preliminary Assessments (PA) in 1986 and 1993;

An ASR in 1994; 

A supplement to the ASR in 2004; 

A Draft Preliminary HRR in 2006; 

A USACE Site Investigation in 2007; 

An Environmental Security Technology Certification Program (ESTCP) Wide Area 

Assessment (WAA) Technical Validation in 2008; 

An ESTCP WAA in 2009; and 

A TCRA in 2010 on a portion of MRS-05. 

A brief summary of previous investigations is included in the following sections. 

1.8.1 Preliminary Assessments 

The USACE, Los Angeles District, prepared multiple PAs in 1986 for individual portions of 

the CSLO. The individual PAs were superseded by a more comprehensive PA that included 

the entire CSLO acreage prepared in 1993 by USACE, Los Angeles District. The 1993 PA 

was the impetus for the 1994 ASR. 

The 1993 PA determined that the site was used for various military activities (e.g., artillery 

and small arms training, including mortar, rocket, and grenade ranges) that included MEC and 

MC and could constitute a public safety hazard. 

1.8.2 Time-Critical Removal Action, 1992 

USACE, Huntsville Division, completed a UXO removal project at the former CSLO, in the 

current El Chorro Regional Park. The site was composed of four distinct areas, totaling 

approximately 95 acres. Three of the areas were suspected impact zones for field artillery and 

small arms practice. The remaining area was identified as a hand grenade practice range 

(adjacent to and/or overlapping the current MRS-01/MRS-02 sites). Of eight UXO items 

discovered during the TCRA (six Mk II fragmentation grenades (live), one Mk II grenade 

body (practice), and one 40 mm anti-aircraft projectile), seven were detonated in place and the 

remaining item (practice grenade) was removed for disposal to the closest Defense 

Reutilization and Marketing Office.

August 2011 1-22 FINAL 

1.8.3 Archive Search Report 

The ASR was completed by USACE, Rock Island District, in September 1994 (CEMVR, 

1994). The ASR presented its findings of an historical records search and SI for ordnance and 

explosive waste at CSLO that included confirmed ordnance presence based on available 

records, as well as an evaluation of potential ordnance contamination based on site ordnance 

components and site information. The ASR reported that 9,159 acres of the CSLO were 

eligible for the DERP-FUDS. The CNG was active (and remains so) on 5,800 acres of the 

former camp and for that reason, those 5,800 acres were ineligible for DERP-FUDS. 

Included in Appendix E (E14) of the ASR is a 1992 reference to an UXO removal action 

(RA) to be completed by IT Corporation, under contract to USACE. There is no record of 

this RA being completed at El Chorro Regional Park. 

The ASR Supplement was completed by USACE, Rock Island District, in 2004 (CEMVR, 

2004) and summarized the information from the 1994 ASR and other associated 

investigations. The ASR Supplement provided a summary of the retained MRSs, the acreage 

for each MRS, and other pertinent information. The ASR Supplement provided a breakdown 

for each MRS with the standard range configuration based on the use of each MRS. The 

MRSs identified in the ASR Supplement for CSLO, their suspected acreage, and types of 

munitions include: 

MRS-01 – Grenade Court, Range #25 – 10 acres; MK II, Hand Grenade, Frag; M21, 

Practice Hand Grenade; M9A1, Rifle Grenade, Anti-Tank; 

MRS-02 - Grenade Court, Range #26 – 16 acres; MK II, Hand Grenade, Frag; M21, 

Practice Hand Grenade; M9A1, Rifle Grenade, Anti-Tank; 

MRS-03 - Grenade Court, Range #27 – 24 acres; M21, Practice Hand Grenade; 

M62, Practice Hand Grenade; 

MRS-04 - Grenade Court, Range #17 – 2 acres; MK II, Hand Grenade, Frag; M21, 

Practice Hand Grenade; M9A1, Rifle Grenade, Anti-Tank; and 

MRS-05 – Range Complex; 2049 acres; Small Arms, General; M28, Rocket, HEAT, 

3.5-inch. 

1.8.4 Draft Preliminary Historical Records Review 

In July 2006, a Draft Preliminary HRR was completed for CSLO and Baywood Park Training 

Area by USACE, St. Louis District, for the USACE, Los Angeles District (CEMVS, 2006). 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-23 FINAL 

The HRR supplements the original ASRs and compiles data obtained through additional 

historical research. The HRR was primarily focused on identifying historical activities that 

might potentially generate the presence of hazardous substances with an emphasis on 

establishing the types, quantities, and areas of MEC and chemical warfare activities. The 

report concentrated on verifying findings of previous studies and supplementing them, if 

possible, with particular emphasis on filling “data gaps.” As noted in the Draft Preliminary 

HRR, Section 9.4, “The investigation does not represent a comprehensive research effort 

regarding the subject sites as it was limited by time and funds. Research was essentially 

limited to a single repository: National Archives and Records Administration at College Park, 

Maryland (NARA-CP) and only limited records were reviewed there. Research efforts at 

NARA-CP focused on division training records for the divisions using CSLO during World 

War II and Signal Corps school records for the signal school located on the installation during 

the Korean War.” The report notes that the investigation team only reviewed roughly a 

quarter to a third of the research of available records expected to contain information on 

CSLO and Baywood Park Training Area. 

1.8.5 Site Investigation in 2007 

The SI was performed to evaluate evidence for the presence of MEC and MC at CSLO. The 

SI, conducted in 2007, was to determine whether MRSs identified within CSLO warranted 

subsequent characterization as part of a RI/FS, NDAI, or a TCRA. To accomplish this 

objective, qualitative reconnaissance and MC sampling were performed. Five MRSs were 

initially developed, based on target information provided in the “Archive Search Report 

findings Former Camp San Luis Obispo, CA, FUDS Property Number J09CA203105, 

September 1994” and the “Preliminary Historical Records Review Camp San Luis Obispo 

and Baywood Park Training Area, San Luis Obispo, CA FUDS Property Numbers 

J09CA203105 and J09CA203106, June 2007.” Based on the result of the ASR, the HRR, and 

the SI, three MRSs (MRS-01, MRS-02, and MRS-05) were identified for further investigation 

and are included in this RI/FS. The remaining MRSs (MRS-03 and MRS-04) were 

recommended for NDAI. 

The three MRSs included in this RI/FS are shown in Appendix B, and summarized in the 

following sections.

1.8.5.1 MRS-01 and MRS-02 – Grenade Ranges

Grenade Range #25 and #26 consist of approximately 26 combined acres. The historical 

records do not distinguish between these MRSs, and for that reason, they are described 

together in this WP. The MRSs were 5-acre parcels located adjacent to one another, and with 

the danger zone applied to each range, they now overlap. The acreage assigned to MRS-01, 

including the danger zone, is 10 acres; MRS-02, also including the danger zone, is 16 acres. 

The Grenade Courts are located in the far southeast portion of the facility, directly north of 

State Highway 1. The ASR reported two 5-acre grenade courts (MRS-01 and MRS-02) 

located on property owned by San Luis Obispo County (the El Chorro Park). Reportedly, this 

area was swept for military munitions by the USACE (late 1980s) where hand grenade 

fragments and expended fuzes were found. The ASR SI team found one expended hand 

grenade fuze north of the baseball fields. The following types of munitions are suspected or 

known to have been used in MRS-01 and MRS-02: 

Grenade, Rifle; 

Grenade, Hand Practice; and, 

Grenade, Hand. 

1.8.5.2 MRS-05 – Range Complex

The Range Complex consists of 2,523 acres situated north of State Highway 1 and spanning 

from the western boundary to the eastern boundary, with all ranges facing north to northeast. 

Multiple use ranges associated with this MRS include, but are not limited to: 

3.5” Rocket Range, Range #15; 410 acres; 

Known Distance 30 Cal, Range #14; 709 acres; 

Rifle Range, Range #13; 407 acres;

1.8.6 ESTCP Wide Area Assessment 

During an ESTCP UXO classification pilot study in August 2009, ESTCP identified over 

2,500 anomalies and destroyed by blow-in-place (BIP) 26 UXO items at a 10-acre test area 

within MRS-05. UXO that were found included 18 60-mm mortars, 4 81-mm mortars, a 37-

mm projectile, a 5-inch rocket warhead, a 2.36-inch rocket, and a 3-inch stokes mortar. Four 

of the UXO items were found on the surface, while the remainder was found in the shallow 

subsurface. 

1.8.7 Time-Critical Removal Action, 2010 

A TCRA was conducted during the autumn of 2010 on approximately 170 acres of MRS-05. 

The TCRA consisted of detector aided visual surface sweeps (using 200 foot by 200 foot

grids) to locate and remove munitions debris (MD) and locate UXO and MEC items. 

Approximately 5,500 pounds of MD were inspected, certified clear of hazardous/explosives 

material, and removed from the site. Twenty-three UXO/MEC items were located and 

disposed of on-site during the TCRA field activities. An additional task during the TCRA 

was to place nine warning signs indicating potential UXO hazards in the area. The signs were 

placed at locations identified by Cal Poly and San Luis Obispo County (Figure 2, ERRG, 

2011).

The following table summarizes the MEC discovered and detonated on-site during the TCRA 

field activities:

1.8.8.2 Cal Poly Property MEC Discoveries

The ASR identified and reported numerous accounts of MEC and MD observed on property 

owned by Cal Poly (in MRS-05, etc.) over the years. Munitions that were identified include 

bazooka rounds, white phosphorus items, hand grenades, an 81 mm round, and an artillery 

round. These items were gathered over the years at Cal Poly and stored in a farm building. 

1.8.8.3 Additional Property MEC Discoveries

The ASR identified and reported similar discoveries on other local properties. A grenade was 

found on San Luis Obispo County school property, and artillery items were discovered on the 

Vollmer property. One mortar round was found in 1983 on the Cuesta College property, and 

at the time, the Fort Ord Explosive Ordnance Disposal (EOD) Team was called out to perform 

an ordnance sweep, which had negative results. 

As reported in the ASR, explosive ordnance has been found at the El Chorro Regional Park. 

An impact area was reported on the National Forest System lands. Reportedly, a phosphorus 

grenade was found on the County schools site in 1986 and a mortar was found on the adjacent 

property the same year. Research of San Luis Obispo County Bomb Squad responses for 

1986 revealed a removal of a hand grenade from San Luis Obispo County School property, 

but no 1986 response record was shown for a mortar round. Explosive ordnance has been 

found on Cal Poly University property. Some of these are as follows: 

Bazooka rounds; 

White phosphorus items; 

Hand grenades; 

An 81mm round; and

1.9 SUMMARY OF MEC HAZARD

It is likely that MEC may be encountered during this project. MEC has been discovered in 

the MRS during previous investigations. It is anticipated that the MEC item presenting the 

greatest fragmentation distance is the M1 105mm Projectile. 

The MEC Hazard Assessment (MEC HA) and the MRS Prioritization Protocol (MRSPP) will 

be used to address MEC hazards at the CSLO MRS. 

1.9.1 Munitions and Explosives of Concern Hazard Assessment 

In October 2008, the Technical Working Group for Hazard Assessment, which includes 

representatives from the DoD, Department of the Interior, USEPA, and state regulatory 

officials, produced the technical reference document Interim Munitions and Explosives of 

Concern Hazard Assessment Methodology. The MEC HA was designed to be used as the 

CERCLA HA methodology for MRS where there is an explosive hazard from the known or 

suspected presence of MEC. The MEC HA is structured around three components of a 

potential explosive hazard incident: 

Severity, which are the potential consequences (e.g., death, severe injury, property 

damage, etc.) of a MEC item functioning; 

Accessibility, which is the likelihood that a receptor will be able to come in contact 

with a MEC item; and 

Sensitivity, which is the likelihood that a receptor will be able to interact with a MEC 

item such that it will detonate. 

Each of these components is assessed in the MEC HA by input factors. The sum of the input 

factor scores falls within one of four defined ranges, called hazard levels. Each of the four 

hazard levels reflects site attributes that describe groups of site conditions ranging from 

highest to lowest hazards. The MEC HA hazards levels are: 

Hazard Level 1 – Sites with the highest potential explosive hazard. There may be 

instances where there is an imminent threat to human health from MEC. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-29 FINAL 

Hazard Level 2 – A site with surface MEC or intrusive activities that would encounter 

MEC in the subsurface and the site has moderate or greater accessibility by the 

public. 

Hazard Level 3 – A site that would be considered safe for the current land use without 

further munitions responses, although not necessarily suitable for reasonable 

anticipated future use. Level 3 areas generally have restricted access and low number 

of contact hours and typically MEC only in the subsurface. 

Hazard Level 4 – A site compatible with current and determined or reasonably 

anticipated future use. Level 4 typically have had a MEC cleanup performed. 

The MEC HA does not directly address environmental or ecological concerns that might be 

associated with MEC, nor does it address the criteria of cost. The MEC HA guidance 

document includes an Automated Excel Workbook, which aids in the development of site 

scoring through standardized input and formulas. The automated workbook was used to 

provide the MEC HA score. Results of the HA scoring summary are provided in a summary 

table. 

1.9.2 Munitions Response Sites Prioritization Protocol 

MRSPP ranking will be completed for the CSLO MRSs based on information obtained during 

the SI and RI field sampling/survey programs. The MRSPP rankings are used by the DoD to 

prioritize sites for further actions. In general, the lower the numerical ranking, the higher 

priority the site is given. In compliance with 32 CFR § 179.5, stakeholder input will be 

considered before finalizing the MRSPP score(s) for the MRSs included in this RI. All 

MRSPP worksheets will be included and a summary table will be provided of the MRSPP 

priority rankings for the MRSs investigated at CSLO. 

1.9.3 Nature of Potential Threats 

The primary safety hazards associated with MEC include blast pressure, fragmentation 

hazards, and thermal hazards as follows: 

Blast pressure is the instantaneous pressure increase resulting from a violent release of 

energy from a detonation in a gaseous medium (e.g., air); 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 1-30 FINAL 

Fragmentation hazards result from the shattering of an explosive container or from the 

secondary fragmentation of items in proximity to an explosion; and, 

Thermal hazards are those resulting from heat and flame caused deflagration (a 

process of subsonic combustion that usually propagates through thermal conductivity) 

or detonation. 

The primary MEC hazard associated with this site continues to be the unearthing of munitions 

through natural forces. Given the nature of the military munitions used during activities at 

CSLO, fragmentation and thermal hazards are the most likely impacts and have the potential 

to cause serious injury or death.

3.0 FIELD INVESTIGATION PLAN 

This chapter provides details of the approach, methods, and operational procedures for RI/FS 

field investigation activities at CSLO, including: 

GSV; 

DGM; 

Geophysical data processing; 

Stake-out of geophysical targets; 

Intrusive investigation of geophysical targets; 

Data assimilation/analysis; 

MC sampling and analysis; 

MEC removal and disposal; and, 

Reporting. 

3.1 OVERALL APPROACH TO THE RI/FS

The overall approach to the RI/FS is to address MEC and MC, utilizing comprehensive 

sampling methodologies involving surface visual, geophysical and intrusive investigations, to 

collect data to locate and adequately characterize target areas associated with three MRS. 

Bristol proposes a dynamic approach to the RI/FS based on stakeholder input during the TPP 

meetings. The transect spacing for the CSLO RI investigation was originally determined 

based on the USACE recommendations found in EM-01-1110-4009. Individual coverage 

requirements were determined for the MRS (see Section 3.6.2.3). Further analysis of the 

calculated transect spacing for each individual area was compared with the MGFD for the 

smallest ordnance item of concern within each of these areas to ensure that all of the proposed 

transect spacings would be sufficient to intersect fragmentation arcs (or potential target areas) 

at least twice. Additionally a statistically defensible MC sampling program is also planned 

within the approach. 

Within this approach, the following steps will be followed during the RI: 

Review of existing documents such as the ASR, the preliminary HRR, the SI, and the 

Draft Historic Map and Aerial Photo Analysis (APA) combined with site visits were 

used to develop the CSLO CESM;

Development of a RI/FS WP using information gained during review of archive data, 

site visit, and input/information resulting from the CSLO TPP meetings in accordance 

with project DQOs; 

Division of MRSs into management grids and sectors within the project GIS, to allow 

management and analysis of RI/FS data throughout the project; 

Perform a site-specific GSV in accordance with DID WERS-004.1 to test proposed 

geophysical equipment and techniques for use during the RI/FS; 

Perform a geophysical investigation of MRSs (SI defined targets and associated buffer 

areas) to define target areas; 

Conduct MC sampling, as appropriate for the type of munitions identified; 

Conduct a background metals survey; 

Manage MEC/MD in accordance with applicable regulations and guidance; and, 

Report the findings in a RI/FS report with follow-on Proposed Plan and DDs, as 

applicable. 

3.1.1 Site Characterization Goals 

The purpose of the RI fieldwork is to: 

Identify and to address MEC, MD, and MC to locate and adequately characterize 

target areas associated with three MRS and recommend future actions or NDAI, as 

appropriate; 

Identify potential safety problems associated with the remnant MEC, MD, and MC; 

Identify, evaluate, and recommend response alternatives for the remnant MEC, MD, 

and MC; and, 

Document the selected response alternatives for the areas addressed. 

The potential risk management or response alternatives identified through the RI/FS effort 

will be evaluated based on effectiveness in remediating MEC and MC at the site, 

implementability, and overall cost. The selected alternatives will address MEC and MC 

contamination in a manner that meets the applicable Project Action Levels (PAL) (Table 15-1 

in Appendix E – Sampling and Analysis Plan) for to human health, wildlife and the 

environment with respect to the intended future land use at the site. 

The RI/FS is a continuous process; necessary input includes consideration of the concerns of 

the stakeholders involved. The RI/FS will provide the background, approach, and evaluation 

process for determining the potential hazard that MEC poses to the landowners and public at 
Work Plan Remedial Investigation/Feasibility Study

the CSLO site. The RI/FS will summarize field activities addressed in the WP and outline 

recommendations for future actions based on the methodology described in this chapter. New 

information and further discoveries may affect the findings and recommendations of the 

RI/FS report. For the RI/FS process to be successful, close coordination and cooperation 

between the stakeholders, community, regulators, and technical support personnel must occur. 

In serving as a cornerstone for the long-term risk management effort at CSLO, the RI/FS 

report will identify and evaluate reasonable alternatives and provide recommendations for 

action, where appropriate. Figure 3-1 illustrates the RI/FS decision logic for CSLO.

August 2011 3-5 FINAL 

To achieve the objectives of this RI/FS, the site requires sufficient investigation for the 

presence of residual MEC and MC. Residual MEC will be estimated based on geophysical 

and intrusive data collected during RI investigation activities. Site MEC investigation goals 

include: 

Accurately locating and recording surface MEC; 

Accurately recording geophysical anomalies; 

Properly interpreting the geophysical data; and, 

Properly documenting the intrusive findings. 

Residual MC will be assessed through a biased sampling program for explosives or metals 

residue in site soil. Soil sampling activities will be conducted to determine if MC have been 

released when compared to the applicable PALs and project ambient conditions to confirm or 

deny a release of MC has occurred. In the event that an MC release is confirmed, future 

investigations may be conducted to assess possible impacts to human health, ecological 

receptors, and the environment associated with MC. MC investigation goals include: 

Accurately defining background metals concentrations and MC metals concentrations 

in soil through a sampling and analysis program. Sampling for metals will include: 

Antimony; 

Lead; 

Copper; and, 

Zinc. 

Determine concentration of explosives constituents in soils, if present 

The RI/FS will be considered successfully completed when MEC, MD, and MC are addressed 

to adequately characterize target areas associated within the three MRS, and to allow for the

evaluation of remedial alternatives. 

3.1.2 Data Quality Objectives 

The CSLO DQOs are qualitative and quantitative criteria used to guide sample collection and 

analysis activities. The DQOs for this RI/FS project were developed by the project team 

during TPP sessions prior to conducting investigative activities to ensure that the data 

generated during the execution of the analytical program are of appropriate quality to support 

the anticipated end use of the data. DQOs seek to ensure that the right type, amount, and 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-6 FINAL 

quality of data are collected to accomplish the objectives of the project. The DQOs for this 

project are included in Appendix J. 

The U.S. Environmental Protection Agency (USEPA) has a seven-step process for 

establishing DQOs as published in "Guidance on Systematic Planning Using the Data Quality 

Objective Process" (USEPA, 2006). Each of the seven steps was applied in determining the 

DQOs for the RI/FS as described below. 

Step 1: Problem Statement - The first step in developing DQOs is to define the problem that 

has initiated the study. For the purposes of this RI/FS, the problem statement is: “Do target 

areas exist at the former CSLO (MRS-01, MRS-02 and MRS-05)?”, and if so, "Do the 

remaining potential MEC items and MCs at these target areas pose a hazard to current or 

future land users?”

Step 2: Identify the Decision - The second step in establishing DQOs is to identify the 

decision statement that the study will attempt to resolve. The potential for an explosive safety 

hazard depends upon the presence of three elements: a source: (presence of MEC); a receptor 

or person; and an interaction between the source and receptor (such as picking up the item or 

disturbing the item by plowing). There is no hazard if any one of these three elements is 

missing. Hazard will be assessed by identifying and quantifying (where applicable), each of 

the three elements. Is MEC present? Are receptors present? Is there a possible interaction? 

MC concentrations detected in soil will be compared to PALs as a screening level indication 

of hazard (discussed in Appendix E). The evaluations of site specific analytical results will be 

compared to the screening levels identified in Table 15-1 of the SAP. Based on site-specific 

MEC and MC investigation data, response alternatives will be identified, evaluated, and 

selected for the protection of human health as well as ecological receptors at the site. If 

necessary, additional investigations will be recommended. 

Step 3: Identify Inputs to the Decision - The primary data inputs for the RI/FS evaluation 

include the types, locations and depths of UXO identified at the site, MC concentrations 

detected in soil, and the anticipated land-use of the site. RI Field data inputs include: 

Results of the investigation to locate surface features indicative of MEC usage (e.g. 

MEC/MPPEH/MD, craters, surface scaring, target debris, pits, and trenches); 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-7 FINAL 

Results of the DGM survey based on judgmental survey design to characterize target 

areas and other areas indicative of MEC usage identified by the investigation: 

Number, location, and magnitude of anomalies in locations representative of nontarget conditions and target conditions 

Results of excavations/reacquisition for a representative subset of anomalies 

indicating whether MEC, MPPEH, or MD was present, the depth and orientation 

of discovered objects, and to the extent possible what type of MEC was found 

GPS measurements on survey control points, to confirm accuracy of the units to be 

employed in the field; 

Test results for DGM instruments on representative test plots; 

MC chemical analysis at subset of areas with evidence of energetic remnants and 

metals residue. This will include areas which may not have energetic remnants such 

as small arms ammunition;

Conceptual Exposure Site Models (Appendix J - Project Data Quality Objectives and 

Conceptual Exposure Site Models); and 

Data obtained by others during the SI, WAA, and the 1992 and 2010 TCRA. 

Step 4: Define the Study Boundaries - The geographical boundaries of MRS areas where 

review of the historical data, ASR, HRR, SI, WAA, 1992 and 2010 TCRA and the APA with 

verification site visit indicated potential past training activity are shown in Appendix B. 

Currently, three MRSs have been identified for investigation during the RI/FS based on 

records reviews and the SI. The estimated combined area of the three MRSs is 2549 acres. 

Given that much of the terrain of the larger MRS (MRS-05) is difficult to access, less than 

100% of the area of interest is likely to be available for investigation. Other anthropogenic 

constraints (such as fences, roads, buildings, and power lines) and non-anthropogenic 

constraints (such as cultural and environmentally sensitivity areas, and geologic materials) 

may also limit access throughout the MRSs. The MRS Location Map in Appendix B shows 

the SI-identified former range locations and the RI study boundary. 

Step 5: Develop a Decision Rule - The purpose of the decision rule is to define the parameter 

of interest, specify the action level, and integrate DQO outputs into a single statement that 

describes a logical basis for choosing among alternative response actions. 

Munitions Constituents - If MCs are detected at concentrations greater than the applicable 

PALs established for the project (see Table 15-1 in the SAP), then additional sampling is 

required to define the nature and extent of MCs. Results of the geophysical investigation will 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-8 FINAL 

be used to define the location and boundaries of sampling towards areas with the highest 

density of MEC. 

Munitions and Explosives of Concern - If MEC is present, receptors are present, and there is 

possible interaction, then evaluate appropriate response alternatives. Response alternatives 

will then be selected based on considerations of effectiveness, implementability, and cost. 

Step 6: Specify Tolerable Limits on Decision Errors – The transect spacing, survey path 

width and line miles will combine to provide the recommended-minimum coverage for each 

of the specified MRS investigation area. These coverage percentages at the CSLO range from 

0.75% to 7.5% based on the overall dimensions of each MRA. The distribution of the 

transects required to meet the minimum-recommended acreage required by the USACE’s EM 

1110-1-4009, Section 7.10 will be constrained to accessible lands as presented and agreed 

upon at the TPP meetings with stakeholders. Appropriate MC analytical quality levels are 

identified in detail in the UFP QAPP, of the MC SAP (Appendix E). The overall QC program 

for this project is provided in Chapter 4. 

Step 7: Optimize the Design for Obtaining Data - The purpose of this step is to identify a 

resource-effective data collection design for generating data that are expected to satisfy the 

DQOs. The RI/FS geophysical study design is optimized by: 

Placing geophysical transects within the MRSs identified for investigation during the 

CSLO RI/FS based on records reviews and the SI. 

Distributing the geophysical transects throughout each MRS adhering to EM 1110-1-

4009 minimum-recommended coverage guidance and distribute transects to the 

greatest ability within accessible areas and Sensitive Species Constraints. Use 

judgmental transect placement in areas of MRS existing washes in search of errant 

materials that may have been moved by wind and water erosion; and, 

Intrusively investigating all anomalies identified as geophysical targets through 

geophysical data processing and interpretation in accordance with the GSV. 

3.1.3 Data Incorporation into the RI/FS Report 

DGM, intrusive investigation and MC sampling data will be migrated to the CSLO database. 

This database will be managed and updated as additional data are provided or generated. The 

CSLO database will be designed such that specific queries, tables, and reports can be 

generated for analysis and presentation of the existing MEC hazards within each MRS. A

3.1.4 MEC/MC Exposure Analysis 

All relevant data acquired during the RI fieldwork will be migrated to and analyzed within the 

CSLO GIS. Once the nature and extent of MEC/MC contamination at the site are 

characterized during characterization of potential target areas, the potential risk due to 

exposure to MEC/MC contamination will be assessed. The potential risk posed by MEC/MC 

contamination may be characterized by evaluating the ordnance, site characteristics, human, 

and ecological exposure pathways. The ordnance category includes the type of MEC 

identified, the level of sensitivity (i.e., the potential adverse health effects associated with 

exposure to the specified MEC/MC), the density of MEC in a specified area, and the depth of 

the MEC. The investigations will also analyze the potential direct and indirect exposure of 

pathways to terrestrial plants, soil invertebrates, and birds and mammals of each feeding 

guild. At this time, a SLERA is not part of the PWS. However, if future information 

indicates a need for a SLERA due to concentrations of metals above the screening levels 

indicated in Appendix E (CSLO SAP) a recommendation will be made to address this 

pathway. 

3.1.5 Use of TCRA 

TCRA are RAs intended to address the imminent safety hazard posed by the presence of 

MEC/MC, where cleanup or stabilization actions must be initiated within 6 months to reduce 

the hazard to public health or the environment. Once the imminent threat at a site is 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-11 FINAL 

addressed through the TCRA, additional work that is necessary is completed through the nonTCRA process. During the course of the RI/FS process, if an area is discovered that poses an 

imminent danger, USACE will be notified for the purpose of reevaluating the area for a 

TCRA. 

If an evaluation of the hazards warrants a TCRA, a DD will be prepared and submitted. This 

document will contain a location and description of the site, a description of existing 

MEC/MC hazards, current land use activities, and previous actions that have taken place to 

address the MEC/MC hazard. The DD will also include an endangerment determination with 

the following statement: “There is a significant possibility that an individual may encounter 

MEC/MC hazards at this site, and that these hazards may cause injury or death to individuals 

who encounter the hazards if not addressed through the response action described in the DD.” 

There are two types of TCRAs that may be considered during an MEC/MC response action: a 

minimum-scope TCRA and an expanded scope TCRA. During a minimum-scope TCRA, the 

minimum resources necessary to address the imminent threat should be allocated. This could 

include, but is not limited to, removal of surface items, fencing the site in, and posting signs 

warning of the MEC/MC hazard. An expanded-scope TCRA may be selected if it is deemed 

as cost effective to address full cleanup requirements in order to avoid future remobilization 

costs. 

As summarized in section 1.8.7, a TCRA was conducted during the autumn of 2010 on 

approximately 170 acres of MRS-05. 

3.1.6 Follow on Activities 

Upon completion of the RI/FS and associated reports, follow-on activities may include: 

Implementation of Risk Management processes; 

Implementation of remedial actions ; and, 

Implementation of the recurring review processes.

3.3 REMEDIAL INVESTIGATION TASKS

3.3.1 Location Surveys and Mapping

The Location Surveys and Mapping Plan describe the methods, equipment, and accuracy for 

conducting location surveys and mapping of MEC sites. All work will be performed in 

accordance with USACE DID MR-09-007 guidelines. 

3.3.1.1 General

Monuments will be located to provide the best coverage of the study area with respect to 

using these monuments as control points for the geophysical survey and MC sampling. 

Monument locations will be determined by the land survey subcontractor and approved by 

Bristol. 

Equipment used in positional surveying activities on the project will include Real Time 

Kinematics (RTK) GPS base station and rover(s), mapping grade GPS rovers, and survey total 

station. In most cases, survey equipment to be used will be RTK GPS sub-meter capable 

Differential Global Positioning System (DGPS) capable hand-held GPS for surface visual 

surveys; use of other survey equipment and methods will be coordinated with USACE. 

Transect locations will be entered into a GIS database. A tabulated list of monuments, 

corners, starting, ending, turning points or any pertinent survey data will be submitted in 

Universal Transverse Mercator (UTM) coordinates in a Microsoft Excel spreadsheet (version 

98 or higher) following completion of work. In addition, the location of any MEC and MD

items recovered during RI activities, as well as and MC sample locations, will be recorded by 

DGPS in UTM coordinates to the nearest 1-foot. 

3.3.1.2 MEC Safety Provisions

During all initial fieldwork and all intrusive activities, a UXO Technician Level II (or above) 

will accompany the survey crew. The UXO Technician II or above will conduct visual 

surveys for surface munitions prior to the survey crew entering a suspected area, and a 

magnetometer survey of each intrusive activity site to ensure the site is anomaly free prior to 

the surveying crew setting monuments or driving stakes. This individual will not be assigned 

additional survey tasks which would interfere with the MEC safety aspects of area clearance 

for driving stakes, iron pins, monumentation, or other survey control, which will penetrate the 

surface in a potentially MEC-contaminated area.

August 2011 3-13 FINAL 

3.3.1.3 Accuracy

All survey control points will be tied to established monuments with horizontal and vertical 

control of "Class I, Third Order" (accuracy of 0.01 feet) or better IAW USACE DID MMRP09-007. Horizontal control for the site shall be based on North American Datum 83 (NAD83) 

using the UTM Zone 10, Meters. Vertical control, if available and required will also be based 

on either the Metric system and referenced to the North American Vertical Datum 88 

(NAVD88). 

Where existing monuments are inadequate for the requirements of this WP, new control 

points will be emplaced and will be of a permanent nature for recoverability during future 

phases of work within the same project. All control points will be iron or steel pins, concrete 

monuments, or other permanent construction method. The Northing and Easting (Y, X) for 

all control points, grid corners, transect points, and any boundaries or closures will be 

presented in the RI/FS Report. 

3.3.1.4 Plotting/Mapping

The location, identification, coordinates, and elevations of all the control points recovered 

and/or established at the site will be plotted on reproducible media for plan metric or 

topographic maps at the scale specified in the task order. Each control point will be identified 

on the map by its name and number and the final adjusted coordinates and elevations. 

Each map will include a grid north, a true north, and a magnetic north arrow with the 

differences between them in degrees, minutes, and seconds shown. Grid lines or tic marks at 

systematic intervals with their grid values will be shown on the edges of the map. A legend 

showing the standard symbols used for the mapping and a map index showing the site in 

relationship to all other sites within the boundary lines of the project area will be shown. 

The coordinates for the transect markers or sampling grid corners will be shown to the closest 

0.3 m (1 ft). The locations of individual recovered MEC items will be surveyed using GPS 

instrumentation to obtain a horizontal accuracy of ± 0.3 m (1 ft) and plotted and identified on 

the map.

3.3.2 Digital Data 

An overall planimetric design file will be created and digitized into an Environmental 

Systems Research Institute (ESRI) ArcView file at an elevation of zero. Cut sheet plots and 

views into the project data will be created by referencing the planimetric and contour files 

from additional ArcView work files. All associated cell, reference, or attachment files will be 

attached and provided with the digital data set along with all other supporting files or data. 

All data will conform to the Spatial Data Standards for Facilities, Infrastructure, and 

Environment (SDSFIE). All SDSFIE compliant data will be submitted electronically on 

IBM-compatible PC optical media (CDROM or DVD). 

3.3.3 Items and Data 

3.3.3.1 MEC Items

Spatial location of MEC items encountered will be surveyed with GPS technology to mark the 

location of the MEC item. All associated GPS and dictionary data will be submitted in a 

specified ESRI format and/or MEC database to USACE. 

3.3.3.2 Other Items as Required

Throughout the course of the project, it is anticipated that the location of other items or 

features (e.g., roads, firebreaks, fences, power lines) will need to be determined. The location 

of these items will be acquired with GPS technology where possible, and with standard 

surveying procedures where terrain and or vegetation preclude such acquisition. Selection of 

the appropriate survey method for other items will be coordinated with USACE. 

The data items to be delivered and the specific timeframe for delivery will be as specified in 

EM 1110-1-4009, Chapter 8. Deliverables will be submitted in electronic format and will 

include: 

Original copies of all field books, layout sheets, computation sheets, abstracts and 

computer printouts; 

Tabulated listing of all project control markers established and/or used in support of 

the MEC response showing adjusted horizontal and vertical positional values in 

meters. Tabulated listing of all UXO/MEC recovered and any specific anomalies not 

completely investigated; 

Completed Electronic Dig Sheet (EDigS) database forms;

Unique items created and/or used to create the end products and the narrative and 

description required by the PWS; and, 

Required location, project, and transect maps. 

3.4 SURFACE PREPARATION

The clearing of vegetation and surface metal will not be performed during this project. If 

possible, large vegetation and surface items that cannot be moved will be avoided, and the 

transect survey lines moved away from/directed around the items. 

3.5 GEOPHYSICAL SYSTEM VERIFICATION PLAN

The geophysical methods and equipment to be employed during the RI will be assessed 

during the GSV prior to and during field work performance. DGM data evaluation and QC 

will be performed in accordance with the standards and requirements established in the 

“Geophysical System Verification (GSV): A Physics-Based Alternative to Geophysical 

Prove-Outs for Munitions Response” (ESTCP, July 2009). Additional QC evaluation will 

include the USACE performance requirements for DGM methods referenced in DID MMRP09-004. These standards include static and reference item response, determination latency 

correction, sample spacing and foot-print coverage, dynamic detection repeatability, dynamic 

positioning repeatability and anomaly resolution. The measured quality objectives (MQO) for 

establishing the target selection criteria will be based on published EM-61 response values for 

similar ordnance items and analysis of GSV data and results. The data will be reviewed daily 

to verify adherence to the established data quality standards. All data will be reviewed and 

checked for appropriateness and accuracy prior to demobilization from the site to insure 

project completeness. Processed data and QC results will be provided to USACE on a weekly 

basis, as referenced in DID MMRP-09-004. Details of the GSV procedures are included in 

Appendix G. The existing IVS developed during the project start-up will be used for QC, 

instrument testing, and training of geophysical field staff members to be employed during the 

project.

accordance with this Geophysical Investigation Plan, the PWS, the APP, and applicable 

USACE DIDs. 

3.6.1 Site Description 

The CSLO project site description is presented in Section 1.0. 

3.6.1.1 Geophysical DQO

The objective of the geophysical investigation is to accurately locate and record the locations 

of geophysical anomalies (potential MEC) for the purpose of characterizing potential target 

areas. The geophysical investigation areas and identified anomalies will be mapped for 

subsequent evaluation (including intrusive investigations of anomalies where geophysical 

signal strength and amplitude suggest the potential of MEC). 

3.6.1.2 Specific Areas to be Investigated

The geographical boundaries of the project site are shown in Appendix B. 

3.6.1.3 Past, Current and Future Use

The past, current, and future use of the site is presented in detail in Section 1. 

3.6.1.4 Anticipated UXO Type, Composition and Quantity

M6 2.36 in High Explosive (HE) Rockets, M9 HE rifle grenades, M28 3.5 in HEAT Rocket,

the Mk2 Hand Grenades and M21 Practice Hand Grenades in MRS-01 and 02 have been 

identified as likely to be present within the project site. Composition of the expected MEC is 

mostly steel, with some components made of zinc and brass. The quantity of MEC items 

within the project area is currently unknown.

below 12 inches. M1 105mm Projectiles are not expected to be found at depths of greater 

than 36 inches bgs. 

3.6.1.6 Digital Topographic Maps

Refer to Chapter 1 Section 1.5.1 for a description depicting topography and surface water. A

topographical map is included in Appendix B. 

3.6.1.7 Vegetation

Refer to Chapter 1 Section 1.5.2 for information concerning vegetation. 

3.6.1.8 Geologic Conditions

Refer to Chapter 1 Section 1.5.5 for information concerning geology. 

3.6.1.9 Soil Conditions

Refer to Chapter 1 Section 1.5.4 concerning soil conditions. 

3.6.1.10 Surface Water and Groundwater Conditions

Refer to Chapter1 Section 1.5.6 for information concerning surface and groundwater. 

3.6.1.11 Geophysical Conditions

There are no documented background geophysical variations at this site other than the 

naturally occurring magnetic gradient. 

3.6.1.12 Site Utilities

Utilities exist on portions of the site. Prior to the start of field activities, a utility locate will be 

performed and utilities marked. 

3.6.1.13 Man-Made Features

Numerous man-made features and conditions are present within the survey area that may 

affect the geophysical investigations. A limited number of individual parcels have varying 

degrees of development ranging from rudimentarily maintained agricultural land to highly 

maintained recreational areas. Many roads exist across the investigation areas serving as 

access throughout the site and potential sources for cultural debris and uncontrolled disposal 

areas.

3.6.1.14 Site-specific Dynamic Events

There are no known dynamic events that will affect the proposed geophysical investigation 

techniques at this site. However, this area is commonly subjected to elevated wind speeds 

that may create logistical problems during performance of this investigation. 

3.6.1.15 Overall Site Accessibility and Impediments

The project area is characterized by largely undeveloped lands. Site accessibility at the CSLO 

is controlled by two main factors: biological resources (vegetation) and terrain (slope) issues. 

Numerous roads exist throughout this area allowing efficient access to most of the sites. The 

main physical limitations are natural features and fences surrounding private property. 

Per discussions with Mr. Dave Ragsdale (Cal Poly) during the TPP process; Bristol will 

contact Mr. Ragsdale with updates to the project field schedule and project work locations as 

they pertain to Cal Poly property. Mr. Ragsdale will inform Cal Poly departments as 

necessary to keep Cal Poly controlled herd animals segregated from field activities.

3.6.2.2 Project-Specific Constraints

The primary project-specific constraints are vegetation and terrain. 

3.6.2.3 Geophysical Survey Type

InDepth will perform a transect-based DGM investigation over the accessible portions of the 

three MRSs that cover approximately 2,549 acres. All aspects of the geophysical 

investigation will be managed based on a combination of the USACE DIDs, the USACE 

recommendations found in EM-01-1110-4009, the “Geophysical System Verification(GSV): 

A Physics-Based Alternative to Geophysical Prove-Outs for Munitions Response”, (ESTCP, 

2009), and the results of vetting of the MRSs for potential targets from analysis of historic 
Work Plan Remedial Investigation/Feasibility Study

August 2011 3-19 FINAL 

documents, maps, and aerial photography. The purpose of the DGM for the MRSs is to 

define the nature and extent of the target areas. 

The transect spacing for the CSLO RI investigation was originally determined based on the 

USACE recommendations found in EM-01-1110-4009. Individual coverage requirements 

were determined for MRS-01 and MRS-02 (26 acres) and the subdivided areas of MRS-05a

(492 acres) and 05b (1,112 acres). Further analysis of the calculated transect spacing for each 

individual area was compared with the HFD for the smallest ordnance item of concern within 

each of these areas and indicates that all of the proposed transect spacing will be sufficient to 

intersect fragmentation arcs (or potential target areas) at least twice. 

In areas where concentrations of geophysical anomalies are identified along a single transect 

or where surface or subsurface conditions indicate a potential munitions target area, a focused 

delineation may be performed if targets are not identified on adjacent transects. This 

delineation will consist of additional DGM transect surveys to determine if an additional 

target feature exists and the extent of the potential target area. 

The recommended transect spacing developed for use at the CSLO project site are as follows: 

MRS-01 and MRS-02 – 43 feet; 

MRS-05a – 218 feet; and, 

MRS-05b – 437 feet. 

Recommended transect spacing of 43 feet at MRS-01 and MRS-02 (MRS-01 and MRS-02 

Transect Spacing Figure in Appendix B) is based the size of the MRSs and on analysis of the 

potential target areas and their designation as former grenade courts. MRS-01, based on 

historic records, was in use by May 1942 as a practice grenade court. MRS-02, based on 

historic records, was in use by May 1942 as a live (High Explosive) grenade court. Though 

available site plans do not clearly locate either of these grenade courts, the throwing bays 

were readily discernable on aerial imagery of the period. Analysis of historic documents and 

investigations at MRS-01 did not identify any recent MD or MEC finds associated with this 

grenade court. Previous investigations of MRS-02 (in particular the1992 TCRA) found MEC 

items, primarily consisting of MK2 High Explosive Hand grenades, MD in the form of

expended grenade fuzes, and abundant grenade fragments (CEMVS, 2010). 

MRS-05 was sub-divided into two separate target range areas based on analysis of the 

potential target areas and their designation as multiple overlapping ranges. 

MRS-05a (MRS-05a Transect Spacing Figure in Appendix B), based on historic records, was 

potentially in use as early as 1950 as a 3.5 inch rocket range. Records from 1953 indicate that 

this rocket range had ten firing points. According to historic documents, there were also 

multiple small arms firing ranges associated with MRS-05a (CEMVS, 2010). The 

recommended transect spacing of 218 feet is based on the size of the sub-division and will be 

sufficient to delineate M9A1 Rifle grenade target arcs based on minimum fragmentation 

distance. Target areas identified by the photo analysis document are expected to be covered 

by the transect surveys. 

MRS-05b (05b Transect Spacing Figure in Appendix B), based on historic records, was 

potentially in use as early as 1942 as a towed 37mm gun target range overlapping an impact 

area, in use by 1950, for 60mm, 81mm, and 4.2 inch mortar rounds. Historic photos 

substantiate the firing of 81mm and 4.2 inch mortars, but also that established firing points 

were not identifiable. According to historic documents, there were also multiple small arms 

firing ranges associated with MRS-05b. Previous investigations of MRS-05 (in particular the 

2009 ESTCP UXO Classification Pilot Project) found MEC items (including 60 and 81mm 

mortar) and MD items (associated with 4.2 inch rockets, 75mm guns, and practice bombs). 

The mortar rounds were expected based on historic evidence, but several unexpected items 

were discovered (including a 2.36 inch rocket and a 5 inch rocket warhead (CEMVS, 2010). 

The recommended transect spacing of 437 feet is based the size of the MRS and will be 

sufficient to delineate 61mm mortar target arcs based on minimum fragmentation distance. 

Target areas identified by the photo analysis document are expected to be covered by the 

transect surveys. 

A scenario was processed through VSP using the following assumptions: 

Using half of the HFD to provide the probability of detection for 2 transects to 

encounter a given target. 

Basing the probability of detection on the proposed transect spacings for each portion 

of MRS-05 (a and b). 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-21 FINAL 

The analysis yielded the following: 

Based on the VSP results a transect spacing of 218 ft in MRS-05a is sufficient to result 

in a 99% probability of detection for a 2.36 inch rocket target and a 99% probability of 

detection for the M9A1 rifle grenade target. 

Based on the VSP results a transect spacing of 437 ft in MRS-05b is sufficient to 

result in a 97% probability of detection for a 37mm HEI target area and significantly 

better for the larger ordnance items.

The DGM procedures to be used during the RI include the GSV for system testing, 

standardization and QC. The DGM activities include: data acquisition, data processing, data 

interpretation, and data management. These DGM procedures follow the best practices and 

standards established by the USACE as outlined in DID MMRP-09-004, the USACE MMRP 

EM-1110-4009 (2007), the “Geophysical System Verification(GSV): A Physics-Based 

Alternative to Geophysical Prove-Outs for Munitions Response”, (ESTCP, 2009), and the 
Work Plan Remedial Investigation/Feasibility Study

latest systematic approach to data acquisition and data QC using physics based alternatives to 

the geophysical prove-outs. The data processing and interpretation procedures follow the 

industry standard procedures for positioning, corrections, and interpretation of the DGM 

results. The equipment and procedures associated with each step are described in the 

following sections. 

3.6.2.3.1 Equipment and Navigation and Mapping System 

InDepth will use the Geonics EM61-MK2A time-domain electromagnetic metal detector to 

perform the DGM operations. These systems will be coupled with a survey-grade RTK GPS 

will be used to position the data. Survey data will be spaced at the agreed upon intervals for 

each MRS throughout the accessible areas of the site. The EM61-MK2A will be operated on 

wheels with the coils oriented with the 1-meter axis perpendicular to line direction. The 

geophysical and positional data will be logged and stored together in one file. All geodetic 

coordinates will later be converted to UTM NAD83 coordinates in US survey feet. 

3.6.2.3.2 Geophysical Equipment 

The primary geophysical equipment used during this investigation consists of the Geonics 

EM61-MK2A high-sensitivity metal detector. The EM61-MK2A is a time-domain 

electromagnetic induction metal detector capable of detecting both ferrous and non-ferrous 

metals. The EM61-MK2A system consists of an air-cored coil, a digital data recorder, 

batteries, and processing electronics. Two deployment options may be used during this 

investigation: a single-coil man-towed configuration and a single-coil machine-towed 

configuration. The arrangement for all coil systems is such that there is a vertical separation 

of 40 cm from the ground surface to the coil. The single-coil man-towed system will utilize 

the instrument manufacturer’s standard deployment. The single-coil machine-towed system is 

deployed using a custom coil deployment platform designed to maintain the manufacturers 40 

cm coil to ground surface separation when being transported with the UTV. 

The EM61-MK2A generates a pulsed primary magnetic field that induces eddy currents in 

nearby metallic objects. When the current is eliminated, the decaying magnetic field from 

metallic objects induces a current in the receiver coils. The induced current is then measured 

at several specific time intervals (time gates) after the primary field is shut off. The secondary 

voltage from the decaying eddy currents can be measured at up to four different time gates 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-23 FINAL 

(256, 406, 706, and/or 1306 microseconds). Using the single-coil geometry the decaying 

eddy currents can be measured, by the same coil, at all four time gates to evaluate decay curve 

characteristics. The induced eddy currents dissipate rapidly in low conductivity materials

(e.g. soils), but induced eddy currents persist for longer periods in high conductivity materials 

(e.g. metal objects). By making the eddy current measurement a relatively long time after 

termination of the primary pulse, the response is nearly independent of the conductivity of soil 

materials. 

3.6.2.3.3 Positioning Equipment 

Geophysical data positioning was accomplished using a Trimble 5700 GPS base station with 

TrimMark III radio and Trimble 5700 GPS Rover coupled to the geophysical equipment with 

the satellite receiver antenna mounted directly above the center of the EM61-MK2A coil. The 

RTK GPS positioning system is capable of providing centimeter-grade accuracy for the 

location of the sensor coils during data acquisition, and recording of site features. The RTK 

GPS will also be used for the stake-out of geophysical Targets of Interest (TOIs). The base 

receiver will be set up over a known “Class 1 Third Order” or equivalent control point or 

benchmark. If no such point exists, one will be established. The accuracy of the GPS rover 

and geophysical data depends partly on the accuracy of the base station location. Other 

factors such as nearby obstructions and time of day may affect the number of satellites visible 

to the GPS and thus the accuracy. Under ideal circumstances, accuracies of 3 cm horizontal 

and 5 cm vertical can be expected when 5 or more satellites are visible. Real-time corrections 

from the base GPS receiver are broadcast to the roving GPS unit via a radio link using a 

TRIMMARK 3 radio modem. This system provides positional updates at a rate of 1 Hertz. 

GPS location data will be collected in Geodetic Coordinates and then converted to 

NAD83UTM Zone 10 North coordinates in US survey feet. 

In addition to the RTK positional recording equipment InDepth uses our proprietary real-time 

Visual Marking System (VMS). The VMS is an automated line marking system that sprays 

biodegradable marks on the ground surface marking the centerline of the DGM system during 

data acquisition activities for visual reference of where data were acquired. These ground 

surface markings are used to aid in positioning adjacent transects and are reviewed in the field 

immediately upon completion of each field investigation segment to assure complete data 

coverage for each area.

August 2011 3-24 FINAL 

3.6.2.4 Target Boundary Definition

The proposed transects are designed using VSP and based on an evenly distributed transect 

approach. The transect spacing and location were subsequently reviewed based on the 

location of the suspected target areas, as depicted in the Draft Historic Map and Aerial Photo 

Analysis to ensure that the transects would cross the suspected target areas. The biasing of 

transects did not preclude areas outside the expected target areas. 

Per discussion during the TPP process; a “radial-approach” using a combination of 

perpendicular transects and diagonal transects at the predicted boundary of the target area 

(defined by more densely distributed fragmentation / munitions debris) will be employed 

during the DGM survey. When the data from transects within a potential impact/target area 

reveals fragmentation, MD or MEC, the teams will perform the additional perpendicular and 

diagonal transects. 

3.6.2.5 Inaccessible Areas

Per discussion during the TPP process; Bristol field teams will perform a “meandering path” 

survey with hand-held magnetometers in areas that are considered inaccessible to the existing 

DGM survey equipment but are still considered accessible to foot traffic. Bristol field teams 

will “mag and dig” potential anomalies / targets during the survey of inaccessible areas. 

Bristol field teams will produce comprehensive documentation (photographs, GPS 

points/boundaries, logbook entries, etc.) of all inaccessible areas. 

Some inaccessible areas will be small enough to affect the distribution of the planned 

transects; however, they may not be large enough to warrant a separate “meandering path” 

survey. The location of all geophysical transects will be placed on a map and compared to the 

desired distribution pattern. In the event that the average path of a mapped transect deviates 

by greater than 20% of the planned transect spacing an evaluation for the cause of the 

deviation will be performed. In the event that the transect path falls in a critical location the 

resolution will be to either perform an additional intermediary transect, or perform a 

“meandering path” to obtain the desired information.

3.6.2.6 Data Processing

Data processing and interpretation will be performed in accordance with the findings and 

results of the IVS. Pre-processing and initial positioning of data will be performed using 

Geonics Ltd DAT61MK2 v2.37 software. Preprocessed data consisting of correctly 

positioned and lag/latency corrected data will be provided in ASCII format. 

Office data processing will be performed using Geosoft Oasis Montaj v7.2 UX-Detect and 

UX-Process software modules for QC evaluation, processing, and interpretation. In 

accordance with optimized site-specific procedures identified through the GSV findings the 

optimum processing parameters will be determined for the production DGM field data. 

Leveled data will be analyzed and targets selected based on the criteria of the project team. 

The initial target selection will be performed based on the results of the leveled channel 2 data 

using automated profile picking routines. Once the targets are selected the response for all of 

the channels will be evaluated and stored for further evaluation including; target size and 

summation response. The DGM interpretation will be verified on a daily basis by reviewing 

the results from the IVS. The TOIs may be further evaluated and prioritized using time-gate, 

time-constant, decay characteristics and target size to eliminate targets resultant of clutter 

items, instrument noise or non-metallic sources. These data will presented as color gradient 

maps of transect data, Geosoft database (.gdb) files of processed data for each data set, and 

.csv files of target lists. 

QC data evaluation will be performed in accordance with the GSV standards and IVS 

requirements established by ESTCP. Additional QC evaluation will include the USACE 

performance requirements for DGM methods. These standards include static and reference 

item response, determination latency correction, sample spacing and foot-print coverage, 

dynamic detection repeatability, dynamic positioning repeatability, target selection and 

anomaly resolution. The data will be reviewed daily to verify adherence to the data quality 

standards. All data will be reviewed and checked for appropriateness and accuracy prior to 

demobilization to insure project completeness. Processed data and QC results will be 

provided to Bristol on a weekly basis.

3.6.2.8 Personnel

The geophysical data acquisition program will be managed by a qualified geophysicist. The 

qualified geophysicist will have a degree in geology, geological engineering, or a closely 

related field and a minimum of 5 years of directly related geophysical experience. A UXO 

Technician II or above will be present to provide avoidance during field activities. 

3.6.2.9 Production Rates

The proposed work week is four 10-hour days. It is estimated that the geophysical field team 

can map an average of approximately 5 miles per day based on a combination of the machinetowed single-coil and man-towed single-coil system, considering access and terrain associated 

with the site. 

3.6.2.10 Measured Data Quality Objectives

Testing in the IVS area (Section 2.1) will demonstrate the ability of the system to achieve the 

specific MQOs outlined in the following sections. The DGM system will not be used for site
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-27 FINAL 

surveys until it is able to meet the MQOs or until the project team agrees on reasoning behind 

a MQO not being met and an appropriate revised MQO is prepared. 

3.6.2.10.1 DGM System Positioning 

The MQO for DGM systems positioning is that the coordinates being obtained from the 

positioning system are of sufficient accuracy to allow for appropriate relocation of MEC items 

for intrusive investigation. The measurement performance criterion for this is that the 

positional error at known monuments will not exceed ±10.2 cm (4 inches). This will be 

evaluated by occupying and recording the position of a fixed survey monument on a daily 

basis such that the positioning system in use passes QC Test #2 (Record Sensor Positions). 

3.6.2.10.2 Along-Track Sample Spacing 

The MQO for along track data density is to have sufficient data collected along each line to 

detect munitions items of interest. Industry experience has demonstrated that a data density of 

at least one reading every 0.66 feet is adequate to achieve this purpose. The measurement

performance criterion is that at least 98 percent of possible sensor readings in a dataset are 

captured at 0.66 feet or lesser spacing between points. In addition, any unidentified data gap 

of 2 feet or greater does not meet the MQO. This will be evaluated using the embedded 

QA/QC modules within Geosoft’s Oasis Montaj UX-Detect data processing and analysis 

program. 

3.6.2.10.3 Cross-Track Line Spacing 

Because this is a single-pass transect-based RI/FS DGM investigation to evaluate nature and 

extent; a MQO for cross-track line spacing is not required. 

3.6.2.10.4 DGM System Data Repeatability 

The MQO for DGM system data repeatability is that the system responds consistently from 

the beginning to the end of an operation. The measurement performance criterion is that the 

response to a standardized item will not vary more than ±20 percent. This will be evaluated 

during the GSV by ensuring that, on a daily basis, the geophysical system being used passes 

QC Test #3 (Static Background and Static Spike). Additionally the response of the ISOs in 

the IVS will be recorded and evaluated by comparing it to the expected response from 

calculated NRL curves on a daily basis. The response for each ISO will be stored within a 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-28 FINAL 

project database to provide daily comparison and tracking to ensure that the response is not 

less than 20 percent below the documented average response anticipated for each ISO of 

concern. 

3.6.2.10.5 Target of Interest Selection 

The MQO for target selection will be established from institutional knowledge, and published 

values for the response from the smallest ordnance item identified on this site (the 60-mm

mortar and M9A1 rifle grenade for MRS-05 and the Mk2 hand grenade for MRS-01 and 02). 

The initial target selection criteria will be conservatively based on these values and the site 

noise characteristics. The initial target selection criteria will be verified during the excavation 

process. All targets greater than 1.5 times the root mean square noise threshold will be 

selected for consideration. These targets will be further evaluated based on the empirical 

results from the IVS and compared to the response levels of the ISO in their least favorable 

orientations. Finally, the geophysical results will be compared to published response values 

from the anticipated (or equivalent) ordnance items to further evaluate the anomalous 

responses. These processes are designed to meet the criteria identified in the IVS/GSV 

documentation for TOI; however, there may be need to investigate additional anomalies based 

on unanticipated geophysical signal. Further refinement of the initial target selection criteria 

may be performed as intrusive investigation data is acquired.

3.6.2.11 Quality Control Tests

Geophysical instruments will be field tested daily to ensure that they are operating properly. 

If the standard response cannot be attained, the instrument will be re-calibrated, repaired, or 

replaced. The following procedures will be conducted during the course of the project: 

Warm-up time (a minimum of 5 minutes or until readings stabilize) each time the sensor is 

turned on. 

DGPS will be checked at a known point once a day (reoccupation test) with day-to-day 

location offsets within +/- 4 inches (10 cm) of the known location (i.e., hub or other surveyed 

point). 

A static background and static spike test will be conducted at the beginning and end of each 

day, during which readings will be collected for no less than 3 minutes. The data from the 

static test will be evaluated for consistency and repeatability. A standard response test will 

then be performed using a standardized reference item placed at a fixed location within the 

EM61-MK2A coils. Static background data will not vary more than +/- 2.5 mV peak to peak, 

and the response to the standardized reference item does not exceed +/- 20 percent of the 

expected value after background correction. 

Personnel Tests will be conducted each time the sensor is assembled, typically at the 

beginning of the day. Response variation in the Personnel Tests will not exceed +/- 2 mV 

peak to peak. 

Cable Shake tests will be performed each time the sensor is assembled, on a daily basis, and 

any time that a cable is replaced. Sensor signals will primarily be monitored for shakeinduced data spikes. Response variation in the Cable Shake Tests will not exceed +/- 2 mV 

peak to peak. If data spikes are evident, a root cause analysis will be conducted by the 

geophysical subcontractor. Once the problem has been identified and corrected, the cable 

shake test will be repeated. Once the problem has been verified to have been corrected, 

geophysical operations may resume.

Data will be collected over the IVS test strip in multiple passes at the beginning of the project 

and after any equipment change. Single lines over the buried seed items will be run twice 

daily. Sensor response amplitude variations will not exceed +/- 20 percent of the drift 

corrected average response and positional variations will not exceed +/- 20 cm for each 

survey. 

3.6.2.12 Data Processing, Correction and Analysis

3.6.2.12.1 Initial Field Processing 

Initial evaluation of digital geophysical data will be performed in the field by the geophysical 

team using Geonics software for downloading and viewing of profile lines. Data will be 

reviewed for complete coverage and good data quality. Data will then be exported in an 

ASCII format to allow further evaluation and final processing, using Geosoft Oasis Montaj 

and UX-Detect. Once the data has been prepared and evaluated to ensure its integrity, it will 

be electronically transferred to InDepth’s (Rohnert Park, CA or Golden, CO) office for final 

processing and QC evaluations. 

3.6.2.12.2 Standard Data Analysis 

The primary geophysical data processing and interpretation software will be Geosoft’s Oasis 

Montaj data processing package with the UX-Detect module. Geophysical data processing 

will include the following procedures: 

Conversion to appropriate Geodetic Coordinate System; 

Normalization or leveling (removal of background); 

Lag corrections; 

Digital filtering and enhancement, if applicable; 

Transect-based selection of target picks (above the established mV threshold); and, 

Preparation of geophysical maps and target lists. 

Daily raw data packages will be zipped and placed on the secure project ShareFile site. 

Processed data (in Geosoft Database format) will be zipped and placed on the ShareFile site 

available for weekly review. Target/anomaly databases (in Geosoft Database format) will be 

zipped and placed on the ShareFile site available for weekly review. Finally, intrusive 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-33 FINAL 

target/anomaly databases (in MS Access format) will be placed on the ShareFile site available 

for weekly review. 

3.6.2.12.3 Anomaly Selection and Decision Criteria 

The anomaly selection criteria will be established at or slightly below the anticipated response 

of the potential ordnance items based on the channel 2 response values. In the event of 

relatively small items, the selection criteria may be established slightly above background 

noise levels to allow for detection of all possible ordnance items. Targets will be selected 

from these maps initially by running the data through Geosoft's UX-Detect module. Each of 

the anomalies selected by Geosoft as a target will be analyzed by trained geophysicists, and 

evaluated as to its validity and position. Targets found to be invalid or incorrectly located will 

be removed or adjusted. Additional, anomalies that were not selected by the UX-Detect 

module, yet deemed to represent a potential target, will be manually selected. 

Transects with anomaly densities in excess of 200 targets per acre will be considered high 

density areas. In these areas additional intermediate transects may be added to further define 

the extent of the high density areas. The anomaly density value will be further defined based 

on site background levels and density of observed anomalies. 

The criteria for selecting and locating anomalies for the target list include the following items: 

The maximum amplitude of the response with respect to local background conditions; 

The lateral extent (width) of the response; 

The 2-dimensional shape of the response; 

The location of the response with respect to the edge of the survey area, unsurveyable 

areas, land features, cultural features, or utilities within or adjacent to the survey area; 

and, 

The shape and amplitude of the response with respect to the response of known targets 

from equivalent items. 

The data required to perform anomaly selection and characterization will be stored in 

the TOI database and includes the following: target number, northing, easting, channel 

1 through 4 response values, the summation of the response values, the target width, 

time-gate characteristics, time-constant, decay characteristics and dig priority.

3.6.2.13 Target List Development and MEC Data Management

The anomalies selected as geophysical TOIs within Oasis Montaj will be exported to a 

Microsoft Excel file for migration to the MS ACCESS Investigation Database. Each target on 

the list will be assigned a unique identification. Target lists will be developed on a transectbased system, sorted by peak amplitude response and named accordingly. The intrusive target 

dataset migrated to the Investigation Database will contain the following fields: Target 

identification number (key), Target Name, Transect location, Predicted northing (y), Predicted 

easting (x), Geophysical response based on the drift corrected channel 2 results in milliVolts 

(mV), dig priority, dataset and date. All TOI and MEC data will be managed in Access 

database and Arc GIS. A combination of InDepth’s EDigS system with conventional paper 

dig sheets as backup will be used for field data capture. Figure 3.1 provides a flow diagram 

of the data management process.

3.6.2.13.1 Field Data Collection 

Two methods of field data collection will be utilized; InDepth’s EDigS system and 

conventional paper dig sheets as backup will be used to record the intrusive investigation 

results for the TOIs. 

EDigS uses ruggedized Windows Mobile field computers running customized Visual CE data 

entry templates featuring pull-down menus to collect the field data electronically using touchscreen or keyboard entry methods. This electronic system works in practice much like paper 

dig sheets, but requires that all required information for each TOI investigated must be 

entered before the data record can be saved, ensuring completeness and standardization of 

captured data. Use of this standardized data system allows rapid synchronization of multiple 

EDigS mobile devices to the MS Access Investigation Database and eliminates transcription 

errors associated with the use of conventional paper dig sheets. Once migrated to the 

Investigation Database, the data is checked for gaps, errors, or inconsistencies, and managed 

spatially within the Project GIS. 

Prior to fielding the CSLO EDigS devices, the data structure will be verified and the data 

entry templates will be updated with CSLO specific data. All EDigS devices will be tested 

prior to use by the dig teams. Prior to the intrusive investigation activities, all field personnel 

will be trained on the concepts and use of the EDigS system to create a fully integrated 

approach to the target investigation and data collection process. 

Each morning, the data manager or assistant will ensure TOI investigation files (dig list) have 

been uploaded to the EDigS prior to distributing them to the appropriate dig team for use. 

MEC investigation data uploaded to the EDigS or included on the conventional paper dig 

sheet include the following: 

TOI Name; 

TOI Position (Northing and Easting); and 

TOI Response (mV). 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-36 FINAL 

The printed dig sheet method of data collection will be used as a backup method in the event 

there is an insufficient number of EDigS Devices or database administration personnel are 

unavailable to coordinate the setup of the devices before the start of daily field activities. 

Data will be entered into the EDigS by first selecting the correct record in accordance with the 

flag number and second using the pull-down menus to enter all required data prior to saving 

the record. In addition to the manually entered data, EDigS automatically records the Device 

ID (Team), time and date for each record saved within the device. 

Regardless of the recording method (EDigS or conventional paper dig sheets), the following 

data will be collected for each TOI investigated: 

Item Classification; 

Item Description; 

Orientation; 

Weight (lbs); 

Depth (inches); 

Team; and, 

Date Investigated. 

Any issues concerning the entry of investigation data in the EDigS throughout the workday 

should be reported to the data manager immediately and conventional paper dig sheets should 

be used to record TOI information until the issue is resolved. 

EDigS devices will be returned to the Database Administrator at the completion of each day’s 

field activities for synchronization to the investigation database and for charging to ensure 

devices are prepared and ready for the next day’s use. Upon receipt, the Database 

Administrator will synchronize each EDigS mobile device with the Project MEC 

Investigation database and review the downloaded data for completeness and accuracy. Any 

discrepancies noted will be discussed with the appropriate Dig Team the next morning. 

3.6.2.14 Quality Control Procedures

All QC processes and procedures conducted independently, both in the field, and in InDepth’s 

home office during the geophysical investigations, will be fully documented and made 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-37 FINAL 

available upon request. The QC documentation will also be included as part of the final 

reporting. While site-specific requirements may dictate site-specific processes and 

procedures, the following will be adhered to in all investigations to ensure quality data 

capture, processing, and interpretation and execution of quality workmanship: 

All personnel conducting specific QC tasks will have the appropriate training and 

understanding of their responsibilities. Additionally, these personnel will have the authority 

to stop work and the organizational freedom to identify, evaluate, initiate, recommend or 

provide solutions, and approve corrective actions to ensure all work complies with stipulated 

contractual requirements. 

A daily log will be maintained that will serve to document any instrument malfunction or 

other conditions that may adversely affect data quality or production. Field notes will be 

recorded during data collection in an effort to identify cultural items and any other pertinent 

information, in an effort to aid the offsite geophysical processor. 

Field personnel will verify that equipment is operating properly and that data are repeatable. 

The Lead Field Geophysicist will be responsible for oversight of geophysical QC checks 

during fieldwork and will ensure that good field practices are employed. 

Field personnel and data processors will verify positional accuracy and precision of location 

of the collected data. The geophysical subcontractor will be responsible for management and 

oversight of all QC data associated with post-processing and deliverables. 

Data processors will ensure adequate coverage, completeness of data, and sufficient contrast 

between target and background response to identify significant geophysical anomalies in the 

data. 

Internal QC procedures will be conducted during data processing to ensure data integrity. All 

personnel assigned to the project will ensure that all project MQOs are met. Quality 

management and implemented QCs will ensure that all geophysical investigation MQOs are 

met. Geophysical survey activities and data, both field and processed, will be reviewed in 

accordance with USACE DID MMRP-009-004. QC documentation will be available to the 

USACE Geophysicist through the ftp site discussed in Section 3.6.2.10.2. Available 
Work Plan Remedial Investigation/Feasibility Study

documentation will include data coverage maps, static response graphs, IVS results and daily 

geophysical survey logs. 

Per discussion during the TPP process; daily raw data packages will be zipped and placed on 

the ShareFile site to be accessed by the USACE geophysicist for review and Quality 

Assurance audits. Processed data (in Geosoft Database format) will be zipped and placed on 

the ShareFile site available for weekly review. Target/anomaly databases (in Geosoft 

Database format) will be zipped and placed on the ShareFile site available for weekly review. 

Finally, intrusive target/anomaly databases (in MS Access format) will be placed on the 

ShareFile site available for weekly review. 

3.6.2.15 Corrective Measures

If any significant discrepancies exist in the positioning or repeatability of the data, the 

problem will be identified, resolved, and documented. 

3.6.2.16 Records Management

InDepth will track and account for all field and processing information along with each data 

file from acquisition through delivery and final reporting in accordance with MMRP-09-004. 

All raw and processed survey data will be archived daily. 

3.6.2.17 Interim Reporting

InDepth will report the status of geophysical mapping to the PM on a daily basis. 

3.6.2.18 Map Format

All delivered maps will conform to the format specified in DID MMRP-09-004. 

3.6.3 Geophysical Investigation Performance Goals 

The following three sections describe the performance goals of the geophysical investigation. 

3.6.3.1 MEC Detection

A document released by the Naval Research Laboratory (Nelson, H.H., et al. EM61-MK2A 

Response of Standard Munitions Items, NRL/MR/6110-08-9155, October 6, 2008) charts the 

EM61-MK2A responses of various common ordnance types in most and least favorable 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-39 FINAL 

orientations and at various distances from the coil. These values will be used as a guide for 

evaluating the acceptable performance of the geophysical instrumentation, keeping in mind 

that site conditions and the physical condition of the object play a significant role in the 

ultimate detection depth. If MEC items are recovered from the field area that were not 

detected by the geophysical system, yet fall within the expected detection depth for that 

object, a root cause analysis will be performed to determine the reason for the non-detection. 

If the problem is determined to be with the geophysical system, appropriate corrective actions 

will be implemented and documented. Possible corrective actions may include reprocessing 

of the affected geophysical dataset, selecting additional targets within the affected data set or 

if deemed necessary recollecting the data from the existing dataset. Targeting thresholds will 

be established after DGM is performed at the IVS and in a small portion of the field area. 

With Bristol’s concurrence, InDepth will define a defensible method for prioritizing target 

selections. This method shall involve the review of all data channels of the EM61-MK2A 

(decay curves, channel sums/averages, time constants, etc.) in an effort to accurately target 

MEC-related anomalies while reducing the number of non-MEC related geophysical 

anomalies. One channel will be selected for final leveling (leveling by hand) and for the 

generation of targeted response values. 

3.6.3.2 Horizontal Accuracy

Horizontally, 95 percent of all anomaly stake-out locations must lie within a 20 cm (8 in) 

radius of their original surface location as marked on the dig sheet. However, anomaly 

locations based on single pass transect data may be the result of large targets outside the 

sensor footprint. In this case the reacquired anomaly location may vary significantly from the 

documented anomaly location and will be evaluated on a case by case basis. All excavated 

items must lie within a 1 m (3.3 feet) radius of the surface location as marked in the field after 

stake-out. 

3.6.3.3 False Positives

If there are more than 15 percent “false positives" (anomaly locations that result in no 

detectable metallic material recovered during excavations, calculated as a running average), a 

reevaluation of the data, detection methods being utilized, and overall project QC will be 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-40 FINAL 

performed. Several factors will act to increase false positives potentially above 15 percent 

without meriting corrective action: 

Attempting to locate relatively small items with low amplitude responses as compared 

to noise; and, 

Site conditions, including mineralized soils that are known to create responses that 

closely mimic subsurface metallic objects. 

A written response explaining the reason for the excessive “false positive” results and a 

corrective action plan, if appropriate, will be submitted within 10 days of identification of the 

situation. 

3.6.4 Geophysical Mapping Data 

The following sections describe the management of the geophysical mapping data. 

3.6.4.1 Land Surveying and Mapping

InDepth will use, if available, a previously established monument that meets the standards in 

DID MMRP-09-007, Section1. 

Geophysical mapping data will be provided in accordance with DID MMRP-09-004. After 

collection, the geophysical field data shall be provided in delineated fields as x, y, z, v (1), 

v(2), etc., for delivery. After completion of survey and processing activities, all geophysical 

data will be provided in ASCII XYZ format to include both raw, processed data and final 

target lists. The database and all final geophysical maps will be provided following 

completion of the field work. Maps that display the geophysical anomalies and identified 

physical features shall be delivered in both a PDF format and a spatially-referenced ESRI 

ArcView (9.x) Tiff format. 

3.6.4.2 Geophysical Data Analysis, Field Stake-out, and Reporting

InDepth will provide anomaly target lists in Microsoft Excel format conforming to the format 

specified in USACE’s DID MMRP-09-004.

3.7 INTRUSIVE INVESTIGATION

3.7.1 General Methodology 

Subsurface investigations will be performed within surveyed areas on all anomalies selected 

by the Site Geophysicist. Geophysical targets will be staked out at the predicted locations 

determined during the data processing and interpretation. During the stake out process of the 

transect-based TOIs each target will be reacquired using the EM61-MK2A to accurately 

determine the along-track and cross-track location of the maximum response from the 

identified target. Intrusive investigation teams, equipped with a mini excavator, GPS, field 

computer and hand digging implements will conduct excavations. Intrusive investigation will 

be performed to depth at the specific stakeout flagged location and completion will be verified 

using an all-metals handheld metal detector (White’s) within the radius of investigation. The 

intrusive results will be recorded in the EDigS program and will be reviewed on a weekly 

basis to evaluate the intrusive results for comparison with the geophysical information. 

If the subsurface target is unable to be located, the data for undiscovered anomalies will be 

reviewed by the project geophysicist and the MEC team supervisor(s). If there are no clear 

surface sources (e.g., terrain, vegetation, cultural clutter), and the data at that specific site is 

determined critical to meet the appropriate QC DQO, the locations will be revisited with the 

original geophysical system to confirm anomalous response. If an anomaly is verified, the 

investigation will be to depth of detection. 

Upon excavation, the intrusive investigation team will record the location, identification, and 

attributes of the excavated item (either manually on a dig sheet or electronically in a field 

computer). In the event that MEC other than those expected are encountered, the UXOSO 

will make the determination as to whether actions need to be taken to alter separation 

distances. The USACE OESS will be kept apprised in all such events. 

MEC located during the subsurface search will be reported to the SUXOS. A description of 

all MEC, MD, and non-munitions related debris recovered will be recorded and incorporated 

into the project database. Recorded data will include, where possible, type/size, estimated 

weight, orientation, depth bgs, and description of the item excavated. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-42 FINAL 

MD will be inspected and certified as free of reactive constituents prior to being placed in a 

lockable storage container. 

After confirming that the item causing the anomaly was removed, excavations will be back 

filled and tamped. The excavation site will be returned as nearly as feasible to an undisturbed 

condition. 

3.7.2 Accountability and MEC Records Management 

A detailed accounting will be made of all UXO items encountered during the RI activities. 

This accounting will include the nomenclature (if applicable) type, approximate weight or 

size, depth, orientation, condition, and location of the item indicated. The UXO Tech III 

(team leader) will record specific details regarding the material found, including (but not 

limited to), the following: specific nomenclature, type of fusing, condition, and external 

markings. The X, Y, and Z coordinates and disposition of the item also will be recorded. 

Each suspected UXO item encountered will be entered on the Daily Operations Summary. 

The SUXOS will prepare and submit the Daily Operations Summary using the Daily Field 

Activity Report and/or disposal record. The SUXOS will provide copies of the Daily 

Operations Summary to the Bristol PM. The intrusive investigation data will be compiled on 

a weekly basis and sent to the Bristol PM and Bristol UXO Operations Manager for review. 

Excavated anomaly attributes will also be added to the project GIS database. 

3.7.3 UXO Personnel Qualifications 

It is anticipated that three intrusive investigation teams will be utilized during the RI. A 

SUXOS, and/or UXOQC/UXOSO will be on the project site full-time during the field 

activities. In cases where the field team exceeds 15 persons, the UXOQC and UXOSO 

positions will no longer be combined. The qualifications for these personnel are included in 

Chapter 2, Technical Management Plan, and in Appendix H. 

3.7.4 MEC Intrusive Investigation Locations 

UXO personnel will excavate subsurface geophysical targets identified as a result of the DGM

and data evaluation effort, and picked for excavation by the project geophysicist. During the 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-43 FINAL 

field activities, revised field maps will be generated that illustrate the completed and yet to be 

completed intrusive investigations of selected anomalies. 

3.7.5 MEC Intrusive Investigation Procedures 

3.7.5.1 Subsurface MEC Investigation

The equipment requirements for this activity include: 

Instrumentation including EM-61 MK2, hand-held gradiometers and all-metals 

detectors used to assist in the intrusive investigation of TOIs; 

Miscellaneous common hand tools (e.g., screwdrivers, digging implements); 

Mini-excavator; and, 

Field computers, forms and logbooks to record activities. 

TOIs will be staked out using RTK GPS and the predicted location dug to depth. Hand held 

gradiometers and all-metals detectors will be used to refine the TOI during excavation and 

clear the hole upon completion. An EM61-MK2A will be on site and available for checking 

no-finds and aid in the refinement of targets when necessary. Each instrument will be 

checked daily at a standard location to ensure proper equipment function and operation. 

3.7.5.2 Surface Anomalies

Surface anomalies are those with sources that are fully or partially exposed at the surface and 

that can be excavated using hand tools. These anomalies will be excavated by carefully 

removing the earth overburden using a hand shovel/trowel or other small digging implement. 

Throughout the excavation, the UXO Technicians will use the Schonstedt metal detector 

metal detector to check and verify the proximity of the anomaly source. 

3.7.5.3 Subsurface Anomalies

Subsurface anomalies are those caused by sources located below the ground surface. 

Subsurface anomaly locations will be reacquired using Schonstedt or White’s metal detectors. 

Manual and mechanical methods will be used to excavate subsurface anomalies. Manual 

methods include using digging tools to excavate the earth overburden in 6 inch lifts. After 

each lift, the anomaly location will be redefined with the Schonstedt or White’s metal detector 

and the anomaly source sought using the hand tools. This process will continue until the 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-44 FINAL 

source of the anomaly has been uncovered and identified. When mechanical methods (mini 

excavator) are used to excavate the anomaly, the earth overburden will be removed in 3 to 6-

inch lifts. After each lift, the anomaly location will be redefined with the appropriate metal 

detector and the anomaly source sought using hand tools. This process will continue until the 

source of the anomaly has been discovered and identified. 

3.7.5.4 MC Soil Sampling

Soil sampling for MC will be performed at selected locations where visual and geophysical 

data indicate the presence of MEC and/or MD. Upon completion of the geophysical survey, 

Bristol will prepare a sample location map for review by USACE and applicable stakeholders. 

As the intrusive investigation progresses, some of the proposed sample locations may change 

based on subsurface discoveries. Additionally, pre- and post-detonation soil sampling will be 

implemented during the RI field data collection process at locations where a detonation of 

MEC is prescribed and conducted. These samples will be collected and analyzed to evaluate 

what, if any, contaminates may remain at project study areas as a result of the demolition of 

munitions in place and if they would contribute to an environmental hazard to site workers or 

the public. The SAP presents the procedures that will be used during the soil sampling 

process. The SAP can be found in Appendix E of this document. 

Analysis of soil samples at CSLO will be limited to explosives constituents and the following 

four metals, based on TPP discussions: 

Lead; 

Copper; 

Antimony; and, 

Zinc. 

Analysis of soil samples for explosive constituents will be based up the type of munitions 

found.

August 2011 3-45 FINAL 

3.7.5.4.1 Background Metals Survey 

No site-specific statistical evaluation of background metals concentrations has been 

performed in previous investigations. Two sources of information were used to roughly 

determine background metals concentrations at the site during the SI phase: 

Average soil concentrations of elements in San Luis Obispo County, California, 

identified by USGS (USGS 2006), and 

Analytical results of 2 ambient samples collected during the 2007 SI field activities 

within the FUDS boundary in areas outside the MRSs that are not expected to be 

affected by munitions activities; used in the absence of a San Luis Obispo County 

average concentration. 

To provide an indication of the concentrations of metals naturally present at the site, two 

ambient samples were collected during the SI. Because only two ambient samples were 

collected, calculation of a more statistically robust site-specific background value is not 

possible. However, these ambient samples combined with the remainder of the SI samples 

and 5 planned background samples in the RI field program, should provide an indication of 

the range of naturally occurring metals concentrations. The RI samples will be compared to 

the range of naturally occurring concentrations. The SI samples were collected both inside 

and outside of the MRSs, and no MEC or MD was observed in the vicinity of the outside 

MRS sample locations, suggesting that they are likely representative of the naturally 

occurring soils in the area. Subsequent analysis of the samples during the SI did not detect 

any explosives. 

The background metals survey to be conducted to determine the levels of select metals 

naturally occurring in the MRSs will include a suite of analytes limited to lead, copper, 

antimony and zinc. A total of 5 background surface soil samples are expected to be collected 

from 2 to approximately 6 inches bgs, and only from native soils. Background concentrations 

will be determined for surface soils by collecting samples from horizons comparable to those 

for the environmental samples. Sampling is discussed in Table 15-1 and Worksheets #17 and 

#18 of the MC SAP QAPP in Appendix E. 

The background metals survey will be conducted at a location to-be-determined that is outside 

of the MRSs and has not been impacted by range operations activities.

3.7.6 Munitions with the Greatest Fragmentation Distance 

Rockets, mortars, projectiles, and grenades have been identified as likely to be present within 

the MRS. An M1 105mm Projectile has been determined as MGFD for the project area based 

on known or suspected MEC within the study area. Prior to intrusive operations beginning, 

Bristol will establish and maintain exclusion zones (EZ) and team separation distances for this 

site. Figures with separation distances (Q-D arcs) are included in Appendix B. 

3.7.7 Minimum Separation Distances 

The Minimum Separation Distance (MSD) for intentional and unintentional detonations shall 

be as follows: 

Unintentional Detonation MSD for the public or non-essential personnel during 

MEC intrusive (subsurface excavations) operations at the project site will be the 

Hazardous Fragment Distance (HFD), MRS-05 the HFD will be based upon the M1 

105mm Projectile; the HFD for this munition is 335 feet. The team separation 

distance for this munition is 72 feet; and, 

Intentional detonation MSD will be the maximum fragment distance of 1886 feet, 

unless reduced by DDESB-approved engineering controls (sand bag mitigation) at a 

measurement of 24 inches in every direction as determined by the Explosive Site Plan 

(ESP) for this site, then the maximum fragment distance will be reduced to 200 feet. 

Further details concerning the MSD calculations for MRS-05 are provided in the ESP. 

The specified EZ distance will also be enforced during intrusive operations. The purpose of 

the EZ is to protect the public and other personnel not engaged in intrusive activities from 

potential blast hazards. The EZs will be marked by signs and/or barriers and enforced at 

access points and high traffic areas when necessary. Only authorized essential personnel will 

be allowed in the EZ during intrusive investigations. It is understood that the EZ will move 

around the site, as each point is investigated intrusively. 

Any reduction of the specified MSD/EZ distance must be in accordance with the DDESB 

guidelines. 

3.7.8 MEC Identification 

Any suspected or known UXO/MEC encountered during excavation will be clearly marked 

and its position noted on the anomaly dig sheet and other appropriate site maps. The UXO 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-47 FINAL 

Team Leader (UXO Technician III) will evaluate the item found and report the condition of 

the item to the SUXOS. No UXO/MEC will be moved without positive identification of the 

item and evaluation of its condition. No UXO/MEC identified for destruction will be 

removed from its location without coordination between the SUXOS and UXOSO. Both the 

SUXOS and the UXOSO must concur that the item may be moved. 

3.7.9 MEC Removal 

If the excavated anomaly is considered to be UXO, it shall be uncovered sufficiently to obtain 

a positive identification of the item. If the item is identified as UXO, a determination will 

subsequently be made as to whether it is acceptable to move. A determination on moving and 

disposal of UXO will be made by the SUXOS and UXOSO for each occurrence. UXO items 

that are deemed safe to move may be moved closer to other UXO items in order to facilitate 

economical use of detonation cord. Items will be spaced sufficiently apart so as not to 

constitute a higher net explosive weight (NEW) or require an EZ recomputation, if possible. 

If circumstances are such that an EZ recomputation is necessary, TP-16 guidance will be 

followed. Any UXO item deemed unacceptable to move will be BIP. BIPs will be conducted 

in a manner that minimizes impacts to surrounding habitat and wildlife, including direct 

impacts and disturbance impacts. If the UXO cannot be safely disposed under existing 

conditions the Bristol PM and USACE OESS will be notified. In no case shall the SUXOS or 

the UXOSO authorize or undertake destruction of UXO when there is sufficient reason to 

believe that the disposal action will result in property damage. In cases where protective 

measures are necessary, Bristol will use the Buried Explosions Module (BEM) from TP-16 

sandbag mitigation method. 

MC sampling will be performed for MC listed in Section 3.7.5.4.1 prior to and following the 

BIP to evaluate potential impacts to surrounding soils. Excavation and detonation sites will 

be back-filled to the approximate grade of the surrounding soil. 

3.7.10 MEC Storage 

Storage of MEC is not authorized for this project. In the event MEC cannot be disposed of 

during work hours, arrangements will be made to provide security to prevent unauthorized 

access to the MEC until it can be destroyed.

3.7.11 MEC Disposal 

All MEC items and munitions-related material containing explosives will be disposed by 

detonation. The following sections describe the procedures to be followed during demolition. 

Demolition procedures are also detailed in the Demolition SOP. All MEC demolition will be 

recorded in MEC item accountability log. A log of these items will be maintained from 

discovery through demolition; documenting proper disposal. MEC Accountability Log can be 

found in Appendix F. 

3.7.11.1 General Procedures

During disposal of MEC, safety is the primary concern. The most obvious requirements are 

to protect personnel, the public, and the environment from fire, blast, noise, fragmentation, 

and toxic releases. In the event demolition of recovered MEC is necessary, the Bristol 

demolition team leader will contact the local explosives distributor for the delivery of the type 

and quantity of demolition material per procedures outlined in Chapter 5 Explosive 

Management Plan. The SUXOS and Bristol demolition team leader will record usage data of 

demolition material and the nomenclature and quantities of MEC destroyed. The SUXOS 

will be responsible for demolition oversight and for maintaining the required records. 

The fire department will be notified a minimum of 24 hours prior to any scheduled demolition 

operation. During dry conditions (as determined by the fire department) demolition 

operations will be conducted in the morning hours prior to 10:00 am and the disposal site area 

may require wetting in order to help mitigate fire potential. Sand bag mitigation with a water 

tamp may also be opted for as a means of fire mitigation. 

MEC will only be detonated after positive identification. Bristol prefers to use a NONEL 

(shock tube) firing system for initiating detonations as it provides ease of set up, a high level 

of reliability and positive control of the detonation event. Electrical initiation (to include 

remote/wireless firing systems) is the next preferred method as it provides positive control of 

the detonation event. Non-electrical (time fuze) is the least desirable method of initiation as 

positive control of the detonation event is not maintained, it present an additional fire hazard 

and requires a long wait time for clearing of a misfire.

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-49 FINAL 

Demolition operations, when required, will be conducted on the last scheduled day of the 

work cycle. At the point in time that a MEC item has been located on site security will be 

provided during all non operational hours until the item has been disposed of. The UXOSO is 

responsible for determining whether minimum safe conditions to conduct demolition 

operations are met. 

3.7.11.2 MEC

All personnel directly or indirectly engaged in MEC operations are thoroughly trained and 

capable of recognizing hazardous explosive exposures. All personnel are required to read, 

become familiar with, and adhere to the requirements contained in this WP and the project 

APP to ensure that all general safety regulations and safe work practices are observed at all 

times. Absence of a written safety requirement does not indicate that safeguards are not 

required. All demolition/disposal operations will be conducted in accordance with these 

procedures and the procedures outlined in Chapter 5, Explosive Management Plan. 

All UXO subcontractor personnel engaged in MEC demolition activities will follow these 

procedures. However, situations may warrant additional safety measures, such as fire trucks, 

medical personnel, and protective clothing. The UXOSO have the overall responsibility to 

comply with the minimum requirements listed below and has the authority to upgrade as the 

situation dictates. 

Demolition operations will not begin until all non-essential personnel are outside of the MSD 

established for the ordnance or consolidated shots being detonated, in accordance with EM 

385-1-97 and its’ referenced documents. MEC that cannot be moved must be BIP. 

While the SUXOS maintains overall responsibility for all field activities, the UXO 

Demolition Team Leader will coordinate specific demolition activities such as preparing 

explosive set-ups for use, demolition team personnel task assignment, and explosives 

placement. The UXOSO shall be responsible for site-specific training of field personnel 

regarding the nature of the materials handled, the hazards involved, and the precautions 

necessary, and shall be present during all on-site disposal operations. The SUXOS shall 

ensure that the appropriate local authorities are notified prior to on site demolition.

Prior to initiation of demolition operations, all personnel will be evacuated to a distance 

outside the MSD of the MEC being detonated. This distance may be adjusted downwards 

based on approved engineering controls. Prior to priming of demolition charges, all avenues 

of ingress will be physically blocked by project personnel. Radio communications will be 

maintained among all concerned parties. Avenues of ingress will not be opened without the 

express permission of the UXOSO. A constant state of vigilance must be maintained by all 

personnel to detect any intrusion into the MSD. An observer will be stationed at a location 

where there is an unobstructed view of the air and surface approaches to the demolition site. 

It shall be the responsibility of the observer to notify the SUXOS to suspend firing if any 

aircraft, vehicle, or individuals are sighted approaching the general demolition site. The 

UXOSO will assure the area is clear of unauthorized personnel and equipment prior to 

permitting attachment of the initiation devices to the priming charge. 

A minimum of two UXO-qualified personnel, one of whom will be a UXO Tech III, will 

conduct demolition operations. Bristol’s preferred method of firing demolition charges is 

with NONEL (shock tube). The SUXOS in conjunction with the UXOSO will decide which 

firing system is suitable for the specific task to be accomplished. Control of initiation devices 

will remain with the UXOSO until attachment to the firing circuit. 

The following notifications will be made a minimum of 24-hours prior to conducting any 

demolition activity: on-site USACE OESS, FAA, local fire department, local police, and 

stakeholders located in or adjacent to, the MRS where the demolition activity will occur. The 

fire department will be alerted to stand by during demolition operations. In the event of a fire 

site personnel will not attempt to extinguish the fire. Site personnel will immediately 

evacuate the site to beyond the MSD and notify appropriate stakeholders. 

Engineering controls for blast and fragment mitigation may be required for destruction of 

specific MEC items. A copy of the "Use of Sandbags for Mitigation of Fragmentation and 

Blast Effects due to Intentional Detonation of Munitions" will be available at the site office. 

Transportation of MEC and explosives will comply with all federal, state, and local 

regulations. Transportation of explosives and MEC on site is discussed in detail in Chapter 5 

Explosives Management Plan.

August 2011 3-51 FINAL 

Prevailing weather condition information will be obtained from a reliable source such as the 

National Weather Service; this data will be logged before each on site detonation. Demolition 

charges will not be primed or connected for electrical firing during the approach or presence 

of a thunderstorm. Other weather conditions (high winds, dust storms, temperature 

inversions, low-altitude clouds, or cloud coverage of more than 50%) may adversely impact 

planned demolition operations. The SUXOS will consider these conditions when determining 

whether or not to conduct demolition operations. If weather conditions preclude the disposal, 

UXO personnel will secure the UXO with sandbags, and cover and properly mark the area 

until favorable conditions allow the demolition. 

Upon completion of disposal operations, the disposal team supervisor and the UXO technician 

will visually inspect each disposal shot. The disposal team supervisor will perform a visual 

inspection of the disposal site(s). The second person will stand by at a safe distance and be 

prepared to render assistance in the event of an emergency. Upon completion of this 

inspection, and providing that there are no residual hazards, the SUXOS will sound the “all 

clear” authorizing the resumption of site operations. 

3.7.11.3 MPPEH

The following procedures by personnel categories will be followed during the inspection of 

MPPEH and MD recovered during the RI/FS: 

UXO Technician I will only tentatively identify a located item as MD or MEC 

UXO Technician II will inspect each item as it is recovered and determine the 

following: 

Is the item a UXO or a component of military munitions? 

Does the item contain explosives hazards or other dangerous fillers? 

Does the item require detonation? 

Does the item require demilitarization or venting to expose other dangerous 

fillers? 

Does the item require draining of engine fluids, illuminating dials and other 

visible liquid HTRW materials? 

Segregate items requiring demilitarization or venting procedures from those 

items ready for certification; and, 

Items found to contain explosives hazards or other dangerous fillers will be 

processed as MEC and disposed of in accordance with the ESP.

container identification; and seal identification, if required. Bristol will also provide these 

documents in the RI/FS report. 

3.7.11.4 Munitions Debris Certification and Verification

Bristol will ensure that scrap metal generated from the intrusive investigation is properly 

inspected in accordance with the procedures outlined below. Only qualified UXO personnel 

will perform these inspections. The SUXOS will certify, and the UXOQC will verify, that the 

scrap metal is free of explosive hazards. 

DID form 1348-1A will be used as certification /verification documentation. All DD 1348-

1A forms must clearly show the typed or printed names of the contractor’s SUXOS and the 

USACE OESS organization, signature, and contractor’s home office and field office phone 

number(s) of the persons certifying and verifying the scrap metal. 

Upon receiving the unopened labeled containers each with its unique identified and 

unbroken seal ensuring a continued chained of custody, and after reviewing and 

concurring with all the provided supporting documentation, the receiving facility will 

sign for having received and agreeing with the provided documentation that the sealed 

containers contained no explosive hazards when received. This will be signed on 

company letterhead and stating that the contents of these sealed containers will not be 

sold, traded or otherwise given to another party until the contents have been smelted 

and are only identifiable by their basic content; 

Local directives and agreements may supplement these procedures. Coordination with 

the local concerns will identify any desired or requested supplementation to these 

procedures; 

In addition to the data elements required and any locally agreed to directives, the DD 

1348-1A must clearly indicate the following for scrap metal; 

Basic material content (type of metal; e.g., steel or mixed);

Seal identification, if different from the unique identification of the sealed 

container. 

The following certification/verification will be entered on each DD 1348-1A for turn-over of 

scrap and will be signed by the SUXOS and the USACE OESS. 

“This certifies that the material listed has been 100 percent properly 

inspected and, to the best of our knowledge and belief, is free of explosive 

hazards, engine fluids, illuminating dials and other visible liquid HTRW 

materials.” 

3.7.11.5 Maintaining the Chain of Custody and Final Disposition

Bristol, in coordination with the USACE, will arrange for maintaining the chain of custody 

and final disposition of the certified and verified materials. The certified and verified material 

will only be released to an organization that will send notification and supporting 

documentation to Bristol documenting the seal containers have been smelted and are now 

only identifiable by their basic content. 

If the chain is broken, the affected MPPEH must undergo a second 100 percent inspection, a 

second 100 percent re-inspection, and be documented to verify its explosives safety status 

(MD or RD). Material that has been documented as safe is no longer considered MPPEH as 

long as the chain of custody remains intact. A legible copy of inspection, re-inspection and 

documentation must accompany the material through final disposition and be maintained for a 

period of three years. 

This documentation will be incorporated by Bristol into the final report as documentation for 

supporting the final disposition of this scrap metal.

signature of the hazardous waste manifest. 

All licenses and permits required for compliance with applicable Federal, California, and 

local laws, codes, and regulations will be obtained prior to collections and containerization of 

IDW. All work will be accomplished in strict accordance with such licenses and permits. 

All methods used to ship or transport IDW will be in accordance with applicable U.S. 

Department of Transportation (DOT) Hazardous Material Regulation 49 CFR 100-199. All 

required hazardous waste manifests will be prepared by an appropriately trained and certified 

shipping agent or specialist. The manifests will include a correct, complete, and legible 

description of all wastes to be shipped. 

3.9 RISK ASSESSMENT AND ANALYSIS

The MEC Hazard Assessment (MEC HA) and the Munitions Response Site Prioritization 

Protocol (MRSPP) will be used to evaluate MEC hazards at the CSLO MRS. 

3.9.1 Munitions and Explosives Hazard Assessment 

In October 2008, the Technical Working Group for Hazard Assessment, which includes 

representatives from the DoD, Department of the Interior, EPA, and state regulatory officials, 

produced the technical reference document Interim Munitions and Explosives of Concern 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 3-56 FINAL 

Hazard Assessment Methodology. The MEC HA was designed to be used as the CERCLA 

HA methodology for MRS where there is an explosive hazard from the known or suspected 

presence of MEC. The MEC HA is structured around three components of a potential 

explosive hazard incident: 

Severity, which are the potential consequences (e.g., death, severe injury, property

damage, etc.) of a MEC item functioning. 

Accessibility, which is the likelihood that a receptor will be able to come in contact 

with a MEC item. 

Sensitivity, which is the likelihood that a receptor will be able to interact with a MEC 

item such that it will detonate. 

Each of these components is assessed in the MEC HA by input factors. The sum of the input 

factor scores falls within one of four defined ranges, called hazard levels. Each of the four 

hazard levels reflects site attributes that describe groups of site conditions ranging from 

highest to lowest hazards. The MEC HA hazards levels are: 

Hazard Level 1 – Sites with the highest potential explosive hazard. There may be 

instances where there is an imminent threat to human health from MEC. 

Hazard Level 2 – A site with surface MEC or intrusive activities that would encounter 

MEC in the subsurface and the site has moderate or greater accessibility by the public. 

Hazard Level 3 – A site that would be considered safe for the current land use without 

further munitions responses, although not necessarily suitable for reasonable 

anticipated future use. Level 3 areas generally have restricted access and low number 

of contact hours and typically MEC only in the subsurface. 

Hazard Level 4 – A site compatible with current and determined or reasonably 

anticipated future use. Level 4 typically have had a MEC cleanup performed. 

The MEC HA does not directly address environmental or ecological concerns that might 

associated with MEC, nor does it address the criteria of cost. The MEC HA guidance 

document includes an Automated Excel Workbook, which aids in the development of site 

scoring through standardized input and formulas. The automated workbook will be used to 

provide the MEC HA score. Results of the HA scoring summary will be provided in a

summary table.

4.4 QUALITY MANAGEMENT SYSTEMS

The overall effectiveness of the QC program for this project depends on all field activities, i.e. 

DGM process, surface/subsurface sweeps/clearances, target removal/replacement, rangerelated debris inspection, etc., being conducted in accordance with the WP. This allows 

for/ensures precision and accuracy of analyses. A specifically accurate and successful 

program is achieved by detecting errors and preventing their recurrence, and by measuring the 

degree of error that is inherent in the activities and procedures being conducted. To ensure 

effectiveness, coherence, and integrity for all activities, the UXOQC, SUXOS, UXO

Technicians, Sampling Technician, and PM will work closely together during all aspects of 

the fieldwork to monitor and document the procedures conducted in accordance with this WP. 

The routine UXO QC procedures to be employed during the project are detailed in this 

chapter of this WP. 

4.4.1 QC Management 

The Bristol corporate QC manager is responsible for the QC programs and reports directly to 

the company presidents. The overall responsibility for implementing and overseeing QC 

activities in the field for this project is with the Bristol PM. The PM is responsible for the 

compilation of all QC documentation during field activities. Incorporated into these are the 

responsibilities of the SUXOS who oversees all site activities and ensures the timely 

submission of all relevant contract deliverables. The specific QC of field UXO operations 

rests with the UXOQC, who coordinates with the SUXOS for daily operations. The UXOQC

will maintain a direct line of communication with the Bristol corporate QC manager. The 

UXOQC will interface with the geophysical survey QC representative. 

4.4.2 Phase Control Process 

The UXOQC is responsible for verifying compliance with project requirements through 

implementation of the three-phase control process. This process ensures that project activities 

comply with the approved plans and procedures. The specific QC monitoring requirements 

for the DFW are discussed below. 

4.4.2.1 Implementation of the 3-Phase Control

The UXOQC is to ensure that the three-phase control process is implemented for each 

definable feature of work, regardless of whether it is performed by Bristol or its 

subcontractors. Each control phase is important for obtaining a quality product. However, 

the preparatory and initial inspections are particularly valuable in preventing problems. 

Production work is not to be performed on a definable feature of work until a successful 

preparatory and initial phase inspection has been completed. 

Elements of the three-phase control process are: 1) Preparatory Phase; 2) Initial Phase; and 3) 

Follow-Up Phase. This process is carried out using checklists developed by the UXOQC. 

Checklists should be developed by reviewing the WP, QCP, quality objectives, and other 

documents relevant to the project. The 3-Phase control process will be documented on the 

QC Daily Report. 

The UXOQC, PM, SUXOS, UXO Technicians, Sampling Technician, and other key 

personnel must work together to ensure project objectives are being achieved. The UXOQC 

is the eyes and ears of the PM and must communicate observations to the PM on a regular 

basis. This may be accomplished during staff meetings, project QC meetings, surveillance 

reports, QC reports, and other means. 

4.4.2.1.1 Preparatory Phase 

Preparatory phase inspections are performed prior to beginning a definable feature of work. 

The purpose of the inspection is to review applicable contracts, plans, specifications, SOP’s, 

and other applicable documents, and verify that necessary resources, conditions, and controls

4.4.2.1.2 Initial Phase 

Initial phase inspections are performed when a work process begins for each crew or team 

performing the process. The purpose of the inspection is to verify work is in compliance with 

procedures and contract specifications, establish acceptable level of workmanship, review 

preparatory phase inspection report, and resolve differences of interpretation. Initial phase 

inspections may be repeated when acceptable levels of quality are not demonstrated or at the 

discretion of the UXOQC. 

The UXOQC is responsible for conducting initial phase inspections and verifying: 

Compliance with procedures and specifications; 

Acceptable level of workmanship is being performed; 

Integrity of the BSP; 

Corrective action taken during the preparatory phase inspection has resolved the 

deficiency and prevents recurrence; and, 

Any differences of interpretation are resolved. 

Deficiencies identified during initial phase inspections will be documented and corrective 

action taken. The UXOQC will verify with the PM that corrective action has been completed 

and is appropriate to prevent recurrence of the condition. When corrective action cannot be 

completed in a timely manner (2 days), or the root cause is not known, immediate corrective 

action that fixes the deficiency may be taken, verified, and work continued pending root cause 

analysis and more appropriate corrective action. 

Initial phase activity will be conducted using QC developed checklists (Appendix F) and 

documented on Daily QC Report. 

4.4.2.1.3 Follow-Up Phase 

Follow-up phase inspections are performed after a work process has begun and periodically 

throughout the work process. The purpose of the inspection is to ensure the process is being 

completed in accordance with agreed upon standards, identify changes in the process, and 

ensure the level of quality meets expectations. The UXOQC is responsible for monitoring 

work processes taking place and verifying continued compliance with contract specifications

and requirements. Follow-up phase inspections are excellent opportunities to observe work 

processes and identify possible process improvements. The UXOQC will maintain the 

integrity of the BSP. 

Follow-up phase activity will be documented on a surveillance report and daily QC report 

(Appendix F). 

Deficiencies identified during follow-up phase inspections will be documented on QC 

checklists (Appendix F) and corrective action taken. 

4.4.2.2 Surveillance

Surveillance shall be conducted to collect objective evidence by the UXOQC in order to 

document and report conditions observed. The QC surveillance is an ongoing process 

throughout the project. Surveillance is a process of monitoring and verifying the status of 

procedures, methods, conditions, products, processes, and services and the analysis of records 

in relation to contract requirements to ensure that the requirements for quality are being met. 

Surveillance will be conducted on a scheduled or unscheduled basis. Surveillance activity 

will be documented on the QC surveillance report and attached to the daily QC report.

4.6.2.2 Definition of Minor and Major Changes and Major Project Impact

Minor Change - A Minor Change is defined as a field change that would not adversely affect 

the quality of the data or product in the field, the rationale for the field procedures, or costs. 

Minor changes may be implemented prior to approval by the PM and the QC Manager. 

Examples of minor changes are as follows: 

Changing the sequence of the field activities; and, 

Changing any of the administrative requirements relative to a remedial effort, with the 

exception of those requirements mandated by federal or state regulations (e.g., chainof-custody procedures). 

Major Change - A Major Change is defined as a field change that will adversely affect the 

quality of field activities, will cause a significant change in the cost or the scope of the 

activity, or will cause significant delays in the schedule. Major changes will require the 

approval of the USACE CO or COR, and the Bristol QC Manager. Examples of major 

changes are as follows: 

Significantly changing the project approach; 

Encountering additional targets to be removed or placed on the project site; and, 

Encountering significantly different tonnages of material than previously estimated. 

A change with Major Project Impact is defined as a change that has a major impact on project 

cost, schedule, and/or technical performance. Some changes defined as major changes may 

have major project impact. Field changes will be documented by completing the FCR Form 

and describing the reasons for the change, the recommended disposition, cost impact, impact 

on previous work, and type of change (Minor, Major, Major Project Impact). The signed and 

dated form will be immediately provided to the PM and QC Manager for review. 

4.6.2.3 Final Disposition

After completion of the review and approval process, the FCR Form will be forwarded by the 

PM to the SUXOS and the QC Manager. If approved, the personnel responsible for the work 

will implement the change. The QC Manager will note final disposition of FCR (e.g., change 

incorporated and work completed, change rejected and work performed per original 

requirements) on the FCR Form.

The QC Manager will verify that all changes to the PWS are marked on all copies in 

use in the field and on file; 

The completed FCR Form will be submitted to the project file; and, 

The PM will incorporate any approved cost adjustments into the budget. 

If an implemented Minor Field Change is not approved by one of the reviewers, it will be 

deemed a nonconforming condition and, as such, will be treated as directed by the procedures 

for Nonconformance/Corrective Action. 

4.6.2.3.1 Field Change Request 

The FCR Form is to be completed for initiating changes to project plans. Approved FCRs 

will be reviewed with project personnel during the Morning Meeting/Safety Briefing prior to 

implementation. 

The initiator completes the FCR Form, then requests assistance from the UXOQC Officer. 

The UXOQC Officer reviews the FCR and routes it to Safety, SUXOS, and PM, as 

appropriate, in turn. The PM submits the FCR to the USACE for approval. The goal is to 

have all FCRs approved or disapproved in no more than 1 week. 

4.6.3 Records 

FCR Forms will be maintained in the project files and available on site. An FCR Form is 

provided in Appendix F. 

4.7 AUDITS

The primary validation tool for QC personnel will be auditing. The specific QC audit 

procedures for the DFWs, including the phase during which it is performed, the frequency of 

performance, the pass/fail criteria and action to take if failure occurs, are presented in this 

section. 

4.7.1 Objectives 

Objectives of QC audits include: 

Evaluate objective evidence that the QCP and WP are being implemented; 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 4-20 FINAL 

Assess the adequacy, effectiveness, and thoroughness of the QCP and WP; 

To verify conformance with approved procedures, WPs, drawings, specifications, and 

procurement documents; 

To identify quality deficiencies; and, 

To verify correction of previously identified quality deficiencies. 

The QA audits include auditor identification, audit notification, audit reporting, identification 

of non-conformances, establishment of corrective actions, and audit completion notification. 

In circumstances where corrective actions have not been completed as planned or scheduled, 

the auditing process provides for management intervention to resolve problems and for 

issuance of stop work orders, if necessary. 

4.7.2 Responsibilities 

The UXOQC is responsible for audit planning and execution. The UXOQC will report audit 

results directly to the PM. Corrective actions based on audit results will be administered by 

the SUXOS in conjunction with the UXOQC. 

4.7.3 Audit Procedure 

Technical specialists must be familiar with the technical and procedural requirements of both 

field and laboratory operations, as well as the associated QA plans. In addition, auditors may 

not be directly involved with the actual tasks themselves to ensure no introduction of bias into 

the auditing process. 

Audits may be scheduled or conducted at random. They may be comprehensive or spot 

checks. The type and method of audit will be established by the UXOQC prior to audit 

performance. 

Audits will be performed on various aspects of each DFW. The type of task being audited 

will dictate the type of audit performed. Field task procedure audits will involve the 

comparison of field activities to written work/safety and field activity SOPs or guidelines. 

Project plan audits will involve review completion documentation and certifications. 

While the majority of the activities will be performed by Bristol, the UXOQC will review 

subcontractor (InDepth, etc.) QC plans, develop an audit plan, and perform an audit of 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 4-21 FINAL 

subcontractor compliance with the subcontractor’s approved QC plan. The USACE OESS, as 

a team partner, will be invited to participate in subcontractor QC reviews and scheduled 

audits. 

4.7.4 Pass/Fail Criteria 

The UXOQC will do a final acceptance inspection on each activity/task. In the event of 

minor deficiencies/non-conformances, he may opt to have the deficiency corrected on the spot 

or correct it himself. In cases where a deficiency/nonconformance rate of 10% or higher is 

noted, he may require that segment of work (i.e., transect, area, etc.) be repeated and reinspected. For the geophysical survey, a missed pseudo-blind seed, may result in a survey 

transect failure and may cause implementation of corrective action to resurvey the transect in 

question based on an evaluation of the root cause of the failure to find the seeded item. 

During intrusive activities missing a pseudo-blind seed item will require analysis to determine 

the reason for the deficiency. If the deficiency is considered a failure then a root cause 

analysis should be performed to determine the cause of the failure. During intrusive 

investigations QC will 10% of picked targets to assure that they have been investigated. For 

scrap inspection / certification, missing one UXO item or item with hazardous or energetic 

material will constitute a failure. The failure may cause re-inspection of the scrap load 

depending on the evaluation of the root cause of the failure. In all cases, a corrective action 

will be determined and implemented. Through observation, the UXOQC will note quality 

trends and will brief during the daily meeting on an as required basis. 

4.7.5 Records 

The UXOQC will keep all audit records on site, and copies of those records will also be 

stored in both the Bristol Anchorage and Sneads Ferry offices. 

4.8 NONCONFORMANCE/CORRECTIVE ACTIONS

The primary purpose/goal of the QC program as defined in this document is to prevent nonconformances and facilitate continual process improvement. To the extent that the first of 

these goals is not achieved, identified deficiencies or non-conformances will be corrected in a 

timely and cost-effective manner, and with the intent of preventing their recurrence. This 

QCP includes provisions for preventing quality problems and facilitating process 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 4-22 FINAL 

improvements, as well as identifying, documenting, and tracking deficiencies until corrective 

actions have been verified. 

4.8.1 Nonconformance Procedures 

All deficiencies or non-conformance conditions discovered during inspections or other QC 

functions will be noted in the Daily QC Report along with corrective actions taken and the 

root cause analysis if applicable. All deficiencies or non-conformance conditions discovered 

during inspections or other QC functions will also be noted on either a Deficiency Notice, or a 

Non-conformance Report as appropriate. These two forms are contained in Appendix F, 

along with appropriate logs for tracking these reports. All deficiencies and non-conformance 

conditions will be resolved prior to completion of the project and in the timeliest manner 

possible. The Deficiency Notice will be used for all conditions that do not affect the final 

work product. A Non-conformance Report will be used when a condition may affect the final 

work product. 

The following procedures have been established to assure that conditions adverse to quality 

such as malfunctions, deficiencies, deviations, and errors are promptly investigated, 

documented, evaluated, and corrected. 

4.8.2 Corrective Actions 

When a condition adverse to quality is noted in the field, the cause of the condition will be 

determined and corrective action taken to preclude repetition. Condition identification, cause, 

reference documents, and corrective action planned, will be documented and reported to the 

Bristol PM and SUXOS. Implementation of corrective actions will be verified by 

documented follow-up action. All project personnel have the daily responsibility to promptly 

identify problem areas, solicit approved corrective actions, and report any condition adverse 

to quality. 

4.8.2.1 Corrective Actions will be initiated at a Minimum:

Corrective actions will be initiated: 

When predetermined acceptance standards are not attained; 

When procedures are determined to be faulty; 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 4-23 FINAL 

When equipment or instrumentation is found faulty; 

When QC requirements are violated; 

As a result of system and performance audits; and/or, 

As a result of management assessment. 

4.8.3 QC Records 

In addition to the project plans and submittals, QC documentation shall be maintained for the 

duration of the project. The QC file will be maintained by the UXOQC and will be controlled 

as an integral component of the project files. It is the responsibility of the UXOQC to 

maintain this project information and keep it current and recorded as it is revised. Technical 

information is not to be replaced or revised without receipt of a properly authorized change 

order or revision. Copies of purchase orders or subcontracts requiring inspections will be 

provided to the UXOQC for receiving and recording purposes. Copies of required 

certifications received will be maintained in the QC file and submitted to the USACE OESS 

in accordance with the contract. 

The Bristol Anchorage, Alaska, office and the Sneads Ferry, North Carolina, office will 

maintain copies of all records of all actions and activities performed by Bristol throughout the 

duration of this project. Personnel and equipment certification / qualification records will be 

maintained at the work site. Authorized personnel / agencies may request access to the 

prescribed records by contacting the PM. 

4.9 LESSONS LEARNED

During the project and at its completion, all actions will be reviewed. Problem areas and 

areas of success will be analyzed for lessons learned. Corrective actions will be reviewed to 

access their impact on the activity in question. In areas where great success was achieved 

factors that directly contributed to the success will be analyzed to determine if they can be 

applied in other areas to improve performance. The overall goal is to ensure past mistakes are 

not repeated and that procedures are improved to better support future similar activities. 

Lessons learned will be addressed in the final report, ensuring the information gained is 

passed to the government.

5.0 EXPLOSIVES MANAGEMENT 

5.1 EXPLOSIVES MANAGEMENT

This chapter describes the procedures applicable in the conduct of explosives management at 

the project site at CSLO. These procedures include Acquisition; Initial Receipt; Storage; 

Transportation; Receipt; Lost, Stolen, or Unauthorized Use; and Inventories. This plan 

applies to all site personnel involved in the conduct of explosives management on the site. 

These procedures are in accordance with: 

Federal Acquisition Regulation 45.5; 

Alcohol, Tobacco, and Firearms (ATF) Publication 5400.7; 

DOD Manual 6055.09M, Volumes 1-8; 

EM 385-1-97, USACE Explosives Safety and Health Requirements Manual; 

DOT Regulations; 

Local/State Laws and Regulations; 

USACE DID MMRP-09-002, Explosive Management Plan; and. 

DA Pam 385-64 

All MEC demolition will be recorded in an MEC item accountability log. A log of these 

items will be maintained from discovery through demolition; documenting proper disposal. 

MEC Accountability Log can be found in Appendix F. 

5.1.1 Acquisition 

Bristol is licensed through the Bureau of Alcohol, Tobacco and Firearms and Explosives 

(BATFE) to purchase and use explosives and will supply commercial demolition material for 

disposal operations at the site. This license will be available on site for local, state, or federal 

inspection. Accountability and use of the explosives will remain with Bristol unless custody 

is transferred to the Government or another contractor with a current BATFE explosives 

license. 

County permits for San Luis Obispo County and BATFE Possessor Forms required to 

conduct explosive operations at the site must be submitted to BATFE within 30 days of 

mobilization for personnel that will handle or have access to explosives. Bristol will obtain 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 5-2 FINAL 

the necessary local permits, submit BATFE Possessor Forms required to conduct explosive 

operations during demolition operations, and maintain these documents on site. 

5.1.1.1 Acquisition Source

Commercial explosives will be purchased from a licensed local commercial supplier. Only a 

responsible personnel meeting ATF criteria for receipt of explosives will be authorized to 

request and receive explosives from the commercial supplier. No other personnel will be 

authorized to receive explosives from the vendor. 

5.1.1.2 Listing of Proposed Explosives

The types of explosives that may be used, but are not limited to, are: 

C-4 demolition charges; 

Non-electric time fuze; 

Non-electric blasting caps; 

Electric blasting caps; 

Time fuze igniters; 

NONEL initiating systems; 

NONEL surface delays; 

Shaped charges (22-gram perforator); 

Detonating cord (100-grain); and, 

NONEL detonators. 

5.1.2 Initial Receipt 

Only the individual named on the Explosive Authorization Form (Appendix F) may sign for 

explosives received from the shipper/vendor. A completed authorization list will be posted at 

the site and provided to the commercial explosives supplier. In order to ensure the quantity 

shipped is the same as the quantity listed on the shipping documents, two UXO personnel 

listed on the explosive authorization list will inventory the shipment prior to signing for any 

demolition materials. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 5-3 FINAL 

5.1.3 Receipt Procedure 

Explosive shipments may be accompanied by the explosive supplier’s/vendor’s bill of lading 

and the freight company's shipping document (if applicable). The initial inventory will 

include reconciling of the two documents, as appropriate, with the actual shipment received. 

Regardless of the outcome of the initial inventory, one copy of the bill of lading and the 

freight company’s shipping document, as appropriate, will be attached to a copy of the 

Purchase Order. One copy of each of these documents will be kept on file at the site field 

office, and one complete copy should be forwarded to the Bristol Corporate Office located at 

111 16th Avenue, Anchorage, AK 99501. 

5.1.3.1 Explosives Receipt Discrepancy

In the event that there is a discrepancy between the quantities of explosives shipped and the 

quantity received, the SUXOS or PM will immediately contact the explosives supplier and 

indicate the discrepancy. It is the responsibility of the supplier and shipper to rectify the 

situation and inform Bristol of the results. The supplier and/or shipper must then correct their 

documents and forward a revised bill of lading to the site. Only the actual quantity of 

explosives received will be signed for on the bill of lading at the time of delivery. 

5.1.3.2 Receipt/Return of Explosive Material

Following each receipt or return of explosive material, the SUXOS will conduct a joint 

inventory in conjunction with the UXO Technician III demolition team leader. Unused 

demolition explosives will be returned to the vendor at the end of daily demolition activities. 

5.1.3.3 Certification

The blaster of record will sign and date the Demolition Record certifying that the explosives 

were used for their intended purpose. 

5.1.4 Storage 

Commercial explosives will not be stored on site. Demolition explosives will be delivered on 

an "as needed/for day use only" basis by the licensed local vendor. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 5-4 FINAL 

5.1.4.1 Establishment of Explosive Storage Facilities

Explosives will not be stored on-site. 

5.1.4.2 Physical Security of Explosive Storage Facilities

Explosive storage facilities are not authorized for this site. 

5.1.5 Transportation 

Transportation of explosives or MEC will be in compliance with all federal, state, and local 

regulations. Off-site transportation of MEC is not authorized. 

5.1.5.1 Transportation to Disposal Location

Bristol personnel will comply with the following procedures when transporting explosives 

and/or MEC to the disposal site: 

Initiating explosives, such as blasting caps, will be separated from other explosives at 

all times in the vehicle. Initiating explosives may be transported in the same vehicle, 

but must be in a separate container and secured away from other explosives; 

All explosives materials/MEC items will be properly containerized and secured in the 

transport vehicle prior to movement; 

Ensure compatibility requirements are met; 

Only a responsible personnel meeting ATF criteria for receipt of explosives (UXO

Technician III or higher) will sign for and supervise the transportation of explosives or 

MEC; 

The driver of the transporting vehicle must possess a valid driver’s license; 

The driver will comply with posted speed limits; however, a safe and reasonable speed 

for actual road conditions will be observed. Drivers transporting explosives or MEC 

off-road will not exceed 25 mph; and, 

No personnel are allowed in the cargo compartment while transporting explosives or 

MEC. 

5.1.5.2 Requirements for Vehicles Transporting Explosives or MEC

The primary procedure for the transportation of explosives will be for the Explosives Vendor 

Delivery Vehicle to deliver explosives on an as needed basis; to remain on-site on a stand-by 

basis during operations; and to remove any unused explosives after demolition operations. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 5-5 FINAL 

The secondary procedure is for the explosives or MEC to be transported in the bed of the 

Bristol Demolition Team vehicle. Day boxes (Type 3) of adequate sizes to contain all 

explosives should be used if the vehicle is not closed with a locking canopy. The following 

requirements apply to each transporting event: 

Vehicles transporting explosives or MEC will be inspected daily using the Vehicle 

Inspection Form (Appendix F) and be properly placarded; 

Vehicles transporting explosives shall have a first aid kit, two 10 lb. BC-rated fire 

extinguishers, and communications with the SUXOS and field office; 

Vehicle engine will not be running when loading/unloading explosives; 

The load shall be well-braced and secured during shipment. Material will be 

transported in day boxes or on a wooden bed liner, dunnage, or sand bags to protect 

the explosives from contact with the metal bed or fittings; and, 

 Vehicle will be properly chocked when parked and loaded with explosives. 

5.1.6 Lost/Stolen or Unauthorized Use of Explosives/MEC 

In the event that there is a discrepancy during any inventory, the item will be recounted a 

minimum of two additional times. If the discrepancy is not resolved, the USACE CO, Bristol 

PM, USACE OESS, U.S. Army CID or Provost Marshal, local law enforcement agencies, and 

BATFE will be notified within 24 hours of identifying the explosives as lost/stolen. 

5.1.7 Return of Unused Explosives 

Explosives that were issued for use, but were not used, will be returned to the commercial 

explosives supplier at the completion of demolition operations and the documentation will be 

maintained in the Bristol field office. 

5.1.8 Procedures for Disposal of Unused Explosives 

At the end of each demolition event, all unused explosives will either be disposed by 

detonation on-site or custody and accountability transferred back to the commercial supplier. 

Documentation for unused explosives sent back to the supplier will be maintained in the 

Bristol field office.

6.0 ENVIRONMENTAL PROTECTION PLAN 

This Environmental Protection Plan has been developed to minimize impacts to the project 

area from RI/FS activities at the Former CSLO. Additionally, it identifies cultural and 

biological resources found in and around CSLO and outlines possible mitigation measures 

that can be used to avoid or lessen the impacts from visual surveys, geophysical survey and 

investigations, MC sampling, and MEC management, if necessary. 

This plan will discuss multiple topics of environmental protection including: 

Wetlands; 

Coastal Zones; 

Cultural and Historical Resources; 

Biological Resources (including Threatened and Endangered Species Protection); and 

Mitigation Measures. 

USACE guidance requires discussion of the following topics when applicable: coastal zones, 

trees and shrubs removed during site activities, burning activities conducted at the site, control 

of water run on and run off, and decontamination and disposal of equipment. These topics are 

not applicable to the CSLO RI/FS; therefore discussion will be very limited. If it is deemed 

necessary to perform one or more of these activities, an attachment to this plan will be 

developed and provided before the activity commences at the project site. This document 

addresses activities planned within the three MRSs discussed in detail in Chapter 1 of this 

document. 

6.1 WETLANDS

The following definition of wetland is the regulatory definition used by EPA and USACE. 

EPA (Federal Register 1980) and USACE (Federal Register 1982) jointly define wetlands as:

“Those areas that are inundated or saturated by surface or ground water 

(hydrology) at a frequency and duration sufficient to support, and that under 

normal circumstances do support, a prevalence of vegetation (hydrophytes) 

typically adapted for life in saturated soil conditions (hydric soils). Wetlands 

generally include swamps, marshes, bogs, and similar areas.” (Title 40 CFR 

232.2(r)). 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-2 FINAL 

USACE regulates wetland uses under the authority of the Rivers and Harbors Act and the 

CWA. USACE requires the use of the “1987 Corps of Engineers Wetlands Delineation 

Manual” for jurisdictional purposes (USACE, 1987). The USACE manual uses a threeparameter method for identifying wetlands requiring positive indicators of hydrophytic 

vegetation, hydric soils, and wetland hydrology. 

Both the city of San Luis Obispo and San Luis Obispo County extract groundwater from the 

San Luis Obispo Valley Groundwater Basin, which underlies the San Luis and Edna Valleys 

and is bounded on the southwest by the San Luis Range, the northeast by the Santa Lucia 

Range, and all other sides by contact with impermeable Miocene and Franciscan Group rocks. 

The southeastern part of the valley is drained by tributaries of Pismo and Davenport Creeks. 

The northwestern part of the valley is drained by San Luis Obispo, Stenner, and Prefumo 

Creeks (State of California, 2004). 

San Luis Obispo/Avila Water Plan Area 4 is classified as intermittently flooded areas situated 

within a topographic depression. Small, temporarily and seasonally ponded depressions 

called vernal pools occur in scattered areas from San Diego County, California, to the Modoc 

Plateau in southern Oregon. These wetlands are found in a variety of landscapes, where they 

are usually underlain by an impermeable layer such as a hardpan, claypan, or basalt. Vernal 

pools often fill and empty several times during the rainy season. Other wetland types in the 

Arid West include seeps near the bases of slopes, wet meadows, wetlands associated with the 

fringes of reservoirs, the wetter portions of riparian forests, and man-made depressions in 

mined areas, agricultural lands, suburban areas (e.g., golf courses), and wetland restoration 

sites. 

The wetlands are covered by shallow water for variable periods from winter to spring, but 

may be completely dry for most of the summer and fall. These wetlands range in size from 

small puddles to shallow lakes and are usually found in a gently sloping plain of grassland. 

Although generally isolated, they are sometimes connected to each other by small drainages 

known as vernal swales. Beneath the vernal pools lay either bedrock or a hard clay layer in 

the soil that helps keep water in the pool. Climatic changes associated with each season cause 

dramatic changes in the appearance of vernal pools. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-3 FINAL 

The pools collect water during winter and spring rains, changing in volume in response to 

varying weather patterns. During a single season, pools may fill and dry several times. In 

years of drought, vernal pools are usually quite small and ponded only during the wetter part 

of the year; however, some pools may not fill at all. 

Appearances may be deceiving, however. The unique environment of vernal pools provides 

habitat for numerous rare plants and animals that are able to survive and thrive in these harsh 

conditions. Many of these plants and animals spend the dry season as seeds, eggs, or cysts, 

and then grow and reproduce when the ponds are again filled with water. In addition, birds 

such as egrets, ducks, and hawks use vernal pools as a seasonal source of food and water. 

The main drainage at the site is Chorro Creek. Surface drainage is generally to the west. The 

Chorro Creek and its tributaries are intermittent and flow only when precipitation is sufficient. 

The Los Osos, Chorro, and Morro Creeks provide drainage to the Los Osos Valley drainage 

basin, where water bearing formations are found. Groundwater in the Los Osos Valley is 

found at depths from 10 to 50 feet bgs. 

Sediment debris is transported by these creeks into Morro Bay during hydrologic events 

(USACE Rock Island District, 1994). 

Potential jurisdictional wetland, such as freshwater marsh, vernal pools, and riparian habitat 

types, are present. Prior to any earthmoving work, a qualified USACE biologist 

knowledgeable and experienced with jurisdictional wetlands will perform the necessary 

delineation. 

6.2 COASTAL ZONES

There are no coastal zones located within the project area. 

6.3 CULTURAL AND HISTORICAL RESOURCES

6.3.1 Existing Waste Disposal Sites Within the Project Site 

It is possible that field investigation teams will encounter existing waste disposal sites that are 

comprised of household-type rubbish. These may contain discarded metal and glass that are a 

safety hazard to project personnel. The field investigation teams will avoid all of these areas 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-4 FINAL 

and notify the SUXOS and UXOQC and/or the UXOSO. Avoidance will consist of adjusting 

the survey area boundaries, or working around these existing waste disposal sites within the 

investigation areas. 

6.3.2 Cultural, Archeological, and Water Resources 

The following sections detail cultural and archeological resources potentially within the 

project boundaries. The information presented for this project was obtained in part from the 

Final TCRA WP (ERRG, July 2010), based on similar field operations.

6.3.2.1 Cultural Resources

Some of the World War II artifacts that remain in the State Parks are dangerous to the public. 

While these artifacts technically and legally meet the definition of a cultural resource, they 

warrant identification and removal by qualified ordnance experts, not archaeologists. Because 

the removal of ordnance is governed by strict rules of documentation, UXO personnel in the 

field serve as recorders of the World War II archaeological record. In the plan below, all 

UXO personnel will be briefed about how to identify cultural resources in the State Parks and 

an USACE archaeologist and a cultural responsible person will be designated from the 

contractor’s team for the field operation. Locations where cultural resources have been noted 

will be recorded with photographs and GPS. Every effort will be made to avoid and leave 

intact cultural resources, both prehistoric and historical. 

6.3.2.2 Regulatory Setting

For federal undertakings, in compliance with the National Historic Preservation Act (NHPA), 

Public Law 89-665; Title 16 United States Code (U.S.C.) 470-470m, as amended; Title 16 

U.S.C. 460b, 470l-470n; and Title 36 CFR Part 800. Cultural resources are located using two 

principal methods. Before starting a project, a records and literature search is conducted at 

repositories of archeological site records. The search may show that an archaeological or 

historical survey has been conducted in the project area and that cultural resources have been 

identified. That information may be enough to proceed with the significance evaluation stage 

of the project. If no previous survey has been done, or if a previous survey was either out of 

date or inadequate, a pedestrian survey of the ground surface within the proposed project 

boundaries may be conducted. Subsurface testing may also be performed if deemed 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-5 FINAL 

appropriate by a cultural resource professional. After a cultural resource(s) has been 

identified during a survey or record and literature search the federal agency overseeing the 

undertaking proceeds to determine whether the cultural resource is eligible for listing in the 

National Register of Historic Places (National Register). Section 106 of the NHPA mandates 

this process. The federal regulation that guides the process is Title 36 CFR Part 800. For a 

cultural resource to be determined eligible for listing in the National Register it has to meet 

certain criteria. The resource has to be either minimally 50 years old or exhibit exceptional 

importance. After meeting the age requirement, cultural resources are evaluated against four 

criteria. The quality of significance in American history, architecture, archeology, 

engineering, and culture is present in districts, sites, buildings, structures, and objects that 

possess integrity of location, design, setting, materials, workmanship, feeling, and association 

and: 

1. that are associated with events that have made a significant contribution to the broad 

patterns of our history; or 

2. that are associated with the lives of persons significant in our past; or 

3. that embody the distinctive characteristics of a type, period, or method of construction, 

or that represent the work of a master, or that possess high artistic values, or that 

represent a significant and distinguishable entity whose components may lack 

individual distinction; or 

4. that have yielded, or may be likely to yield, information important in prehistory or 

history. 

After a cultural resource has been determined eligible for inclusion in the National Register it 

is accorded the same level of protection as a property that is included. It then becomes 

formally known as a “historic property” regardless of age. The following law may also apply 

to the project: 

American Indian Religious Freedom Act of 1978: Public Law 95-341; 42 U.S.C. 1966. The 

American Indian Religious Freedom Act makes it policy of the federal government to protect 

and preserve the inherent rights of American Indians, Eskimo, Aleut, and Native Hawaiian to 

believe, express, and exercise their traditional religions. This includes, but is not limited to, 

access to religious sites, use and possession of sacred objects, and freedom to worship through 

ceremonials and traditional rites. It directs federal agencies to evaluate their policies and 

procedures to determine if changes are needed to ensure such rights and freedoms are not 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-6 FINAL 

disrupted by agency practices. The act also requires the views of Native American leaders be 

obtained and considered where a proposed land use might conflict with traditional Native 

American religious beliefs or practices. 

The type and degree of adverse effect(s) must be assessed and steps must be taken, in 

consultation with the State Historic Preservation Office and Tribal Historic Preservation 

Officer, to avoid, minimize, or mitigate adverse affects. In efforts to reduce vandalism and 

destruction of archaeological sites, it is illegal to collect or disturb historical artifacts located 

within a California State Park. 

6.3.2.3 Historical-Period Cultural Resources

Although the State Historic Preservation Office and Central Coastal Information Center did 

not identify the presence of cultural resources in MRS-05, according to both David Ragsdale 

and Mike Hall, both of Cal Poly, Native American cultural resources are present in MRS-05 

and they are frequently visited by schoolchildren during scheduled field trips (Parsons 

Corporation, 2007). 

6.3.2.4 Potential Impacts of Field Activities

Nonintrusive and intrusive methods of field investigation will be used during field activities. 

Nonintrusive methods include visual surveys conducted by foot or by small utility vehicles 

(e.g. Polaris or gators). 

Intrusive methods include digging up an item after it has been identified by (1) using either a 

handheld metal detector and digging when an item is discovered, or (2) using previously 

recorded data and digging a discrete anomaly identified as potentially containing MEC, or (3) 

blowing in place an item that cannot be removed safely. The method(s) used will be dictated 

by the topography, access, cultural and biological resource considerations, agency approval, 

and other similar considerations on a site-by-site basis. The fieldwork, as planned, has a 

potential to affect sensitive cultural and biological resources in and around the project site. 

Sections below address minimization of these impacts. Because of safety concerns, recording 

of cultural resources at UXO locations will take place after BIP operations.

6.3.2.5 Mitigation Measures

Nonintrusive methods, such as visual surveys and surface clearance operations, have a low 

potential of impacting cultural resources depending on what type of equipment is used to 

conduct the survey. Intrusive methods may impact a cultural resource if the dig area is within 

close proximity of a cultural resource. As noted above, every effort will be made to avoid 

resources once they have been identified. 

6.3.2.6 Worker Education Briefing

Prior to commencement of field activities, all on-site personnel will be briefed on health and 

safety issues and on the cultural resources sensitivity of the area. A cultural responsible 

person will be identified during this briefing to ensure the field teams are educated and trained 

each day to avoid the cultural resources. Methods for minimizing potential impacts on 

cultural resources will form an integral part of the on-site training. 

6.3.2.7 Treatment of Unanticipated Finds

Every effort will be made to identify cultural resources within the project area and to avoid 

them during UXO activities. However, unexpected cultural remains exist, particularly below 

the surface. If prehistoric or historical-period archaeological resources are encountered, the 

location will be noted in the field log and recorded using a GPS unit (if possible). If human 

remains are encountered during the project, the project archaeologist will notify the County 

Coroner. If the human remains are determined to be archaeological in nature, the USACE and 

state archaeologists will be contacted, as will the Native American Heritage Commission. All 

human remains will be left in place until the appropriate action is defined. 

6.3.2.8 NHPA Documentation

The project archaeologist, in coordination with USACE and the state archeologist, will 

prepare all documentation required for compliance with NHPA § 106. The USACE 

archeologist will prepare all cultural resources sections as part of any environmental 

documentation required by the National Environmental Policy Act.

6.3.2.9 Treatment of Unanticipated Finds

Every effort will be made to identify Paleontological resources within the project area and to 

avoid them during UXO activities. In the event that Paleontological resources are 

encountered, the location will be noted in the field log and recorded using a GPS unit. 

6.4 BIOLOGICAL RESOURCES

The former CSLO consists mainly of mountains and canyons classified as annual grassland, 

wooded grassland, oak woodland, and brush. A major portion of the site is identified as 

annual grassland and is used primarily for grazing. Los Padres National Forest (forest and 

woodland) is located to the north-northeastern portion of the site. 

6.4.1 Plant Resources 

Coastal oak woodlands, including coast live oak as a dominant, occur along coastal foothills 

and valleys. On steep slopes, coast live oak occurs as relatively small woodland patches in 

mosaics with annual grassland, scrubland, and riparian habitats (Barbour et. al., 2007). Taxa 

associated with coast live oak on moister sites are Pacific madrone (Arbutus menziesii), 

California bay (Umbellularia californica), tanoak (Lithocarpus densiflorus), and canyon live 

oak. Overstores range from open to nearly closed, resulting in variable cover and richness of 

understory shrubs, grasses, and forbs. Annual grasses form most of the understory in open 

woodlands but are almost nonexistent in very dense woodlands. Coast live oak savannas 

occur adjacent to grassland habitats. Some invasive exotic vegetation, such as Eucalyptus, are 

present in the canyons. Vegetation type descriptions come from Terrestrial Vegetation of 

California (Barbour et. al., 2007, California Native Plant Society Press) and USACE, 

Planning Division, Environmental Resources Branch. 

6.4.2 Animal Resources 

The following sections briefly summarize animal resources within the project site based on 

habitat type (California Natural Diversity Database, 2011). The Coastal woodlands, annual 

grasslands, scrubland and riparian habitats (ephemeral streams) are the primary habitat types 

within the project area.

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-9 FINAL 

6.4.2.1 Fish

Steelhead trout have been documented as occurring in association with Los Osos Creek and 

tributary channels (on or near the project site). This species should be considered as 

potentially present in riparian areas adjacent to the project site. During the proposed 

scheduled field operations, these tributaries are likely to be dry, thereby further reducing the 

potential for impacts to the species. 

6.4.2.2 Amphibians

California red-legged frog has been documented as occurring in association with Los Osos 

Creek and tributary channels. This species should be considered as potentially present in 

riparian areas adjacent to the project site. During the proposed scheduled field operations, 

these tributaries are likely to be dry, thereby further reducing the potential for impacts to the 

species. 

6.4.2.3 Reptiles

Representative animal species of oak woodlands that may occur onsite include arboreal 

salamander (Aneides lugubris), southern alligator lizard (Gerrhonotus multicarinatus), 

common king snake (Lampropeltis getulus).

Reptiles which commonly breed within annual grassland habitats may include western fence 

lizard, gopher snake, and western rattlesnake (Crotalus viridis). 

Common lizards such as western fence lizard (Sceloporus occidentalis) may potentially occur 

within coastal scrub habitats of the project site. Coastal scrub communities on the project site 

may also provide potential habitat for species such as the silvery legless lizard (Anniella 

pulchra pulchra). 

6.4.2.4 Birds

Bird species that may potentially occur in the oak woodland include scrub jay (Aphelocoma 

corulescens), plain titmouse (Parus inornatus), California towhee (Pipilo crissalis), and the 

dark-eyed junco (Junco hyemalis).

Raptors, such as red-tailed hawk (Buteo jamaicensis), white-tailed kite (Elanus caeruleus), 

barn owl (Tyto alba), and American kestrel (Falco sparverius), commonly use open grassland 

areas extensively for foraging purposes, while species such as western meadowlark (Sturnella 

neglecta) use open grassland areas for nesting.

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-10 FINAL 

Bird species that may potentially occur in coastal scrublands include American crow (Corvus 

brachyrhynchos), mourning dove (Zenaida macroura), California thrasher (Toxostoma 

redivivum), and scrub jay (Aphelocoma coerulescens). 

Riparian habitats support a wide diversity of wildlife due to the availability of important 

features such as nesting sites, escape and thermal cover, food, and dispersal corridors. 

Animal species which utilize willow riparian habitat include, but are not limited to: Pacificslope fly catcher (Empidonax difficilis), warbling vireo (Vireo gilvus), western scrub jay 

(Aphelocoma californica), Bewick’s wren (Thryomanes bewickii), Wilson’s warbler 

(Wilsonia pusilla) and American robin (Turdus migratorius). 

6.4.2.5 Mammals

Coast live oak woodland areas on the project site are potential habitat for a wide variety of 

wildlife species, including foraging habitat for mule deer (Odocoileus hemionus), western 

gray squirrel, black-tailed deer, North American raccoon, and Virginia opossum. 

Annual grasslands on the project site may provide foraging habitat for small mammals such as 

voles (Microtus sp.), white-footed mice (Peromyscus spp.), California mouse (Peromyscus 

californicus), Botta’s pocket gopher (Thomomys bottae) and California ground squirrel 

(Spermophilus beecheyi), as well as predators that feed on them, such as coyote (Canis 

latrans). 

Mammals that may potentially occur in coastal scrub habitat present on the project site, 

include brush rabbit (Sylvilagus bachmanii), California mouse, Botta’s pocket gopher, 

California ground squirrel, and raccoon (Procyon lotor). 

Riparian habitats support a wide diversity of wildlife due to the availability of important 

features such as nesting sites, escape and thermal cover, food, and dispersal corridors. 

Animal species which utilize willow riparian habitat include species such as striped skunk 

(Mephitis mephitis), raccoon (Procyon lotor), Virginia opossum (Didelphis virginianus), 

common garter snake (Thamnophis sirtalis). 

6.4.3 Special Status Species 

Four special status listed taxa are present or may be present on the project site, which include 

those found in Table 6-4. Three of the species are present or may be present on the site,

6.4.3.1 Mitigation and Avoidance Measures for Listed Species

The RI/FS investigation foot-print will be relatively small with respect to the total area for 

each of the individual MRS study areas as described in Chapter 3. Coverage ranges from 

0.75% to 7.5% of the total area for each MRS study area. Because the RI/FS field 

investigation will be performed using a transect-based approach these relatively small 

coverage percentages result in fairly widely spaced transect spacing to achieve the desired 

investigation coverage. This fact alone will limit the effect on sensitive species and habitat. 

Recent sensitive species surveys have not been conducted at all MRS. Consequently, the 

specific areas within the project site in which these species may occur have not yet been 

determined. The information presented for this project was obtained from the Final TCRA 

WP (ERRG, July 2010), based on similar field operations. 

6.4.3.1.1 Potential Effects to Wildlife 

Nonintrusive methods, such as visual surveys and surface clearance operations, have a low 

potential of impacting biological resources. The noise generated by the field crews and their 

equipment could disrupt wildlife at the site. 

Intrusive activities have a small, temporary, localized impact at the site of the anomaly 

investigation. Although the disruption should only be temporary, minor disturbances may 

occur to wildlife foraging and cover requirements. 

Minor vegetation damage could occur should items with only a partial aboveground presence 

require excavation to facilitate removal of potential MEC located at the excavation site. This 

minor vegetation disturbance may reduce the available foraging habitat and potentially 

decrease raptor prey populations. This disturbance would be temporary and is offset because 

suitable foraging habitat is present in adjacent areas. The project site will be reconnoitered 

for federal special status sensitive listed taxa prior to any work activity ensuing. All special 

status sensitive listed taxa will be avoided, thus there will be no effect to the species or their 

habitat.

6.4.3.1.2 Worker Education Briefing 

Prior to commencement of field activities, all on-site personnel will be briefed on health and 

safety issues and the ecology of sensitive species in the area. Methods for minimizing 

potential impacts to these species by avoidance will form an integral part of the on-site

training. 

6.4.3.1.3 Special Status Listed Taxa Avoidance 

Incorporated into the field activities will be avoidance of federal special status listed taxa. To 

avoid adverse effects to any federally listed threatened or endangered species, bird species 

protected under the Migratory Bird Treaty Act, and wildlife habitat in general, no activity or 

action will be taken that “may effect” their population or habitat, and field teams will be 

trained on endangered local flora and fauna of CSLO. A qualified USACE biologist 

knowledgeable and experienced with plant and animal ecology will perform the necessary 

biological monitoring, observations, and reporting, as described in Table 6-2.

6.4.3.1.4 Bird Species 

Field activities will avoid the flowering and nesting season for all bird taxa. Pre-project 

surveys will be conducted prior to and after the activities nesting season (March–September) 

in areas where transects may affect breeding species. All activity will be confined to after the 

spring and early summer flowering period. A qualified USACE biologist knowledgeable and

6.4.3.2 Avoid Vegetation Impacts

During field operations, only areas necessary to conduct surface clearance investigations and 

MEC disposal will be disturbed. Equipment staging areas will be established, when possible, 

in already disturbed sites. All listed taxa will be avoided. No vegetation will be removed 

during field operations. A qualified USACE biologist knowledgeable and experienced with 

plant and animal ecology will perform the necessary biological monitoring, observations, and 

reporting, as described in Table 6-2. 

6.4.3.3 Mitigation Measures

The application of mitigation measures, if required, may reduce impacts to plant and wildlife 

species as a result of project-related activities, as described in Table 6-2. The technical 

approach to field operations specifies avoidance of all listed biological resources. 

6.5 MITIGATION

Other foreseeable impacts to the environment can be created from normal logistical activities 

including waste removal and disposal, dust and emissions, storage areas and temporary 

facilities, access routes to the sites and post activity clean up. The following are mitigation 

measures that are to be followed to reduce impacts to the sites and logistical areas 

6.5.1 Manifestation, Transportation, and Disposal of Wastes 

Waste generated during the day-to-day activities will be collected and removed from the site 

at the end of each day, and any IDW will be managed and disposed as described in the IDW 

Plan in Section 3-8. Upon leaving the site, all waste will be disposed of in dumpsters or other 

proper receptacles at the project office location. All pin flags and other marking devices will 

be collected and removed from the site when they are no longer needed. 

MD that is collected during each day will be transported to the project’s MD Storage Area 

location and placed in the bin/container designated for MD. 

6.5.2 Burning Activities 

No burning activities will be taking place during this project. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-17 FINAL 

6.5.3 Dust and Emission Control 

Survey activities will likely generate minimal fugitive dust and other emissions. The survey 

methods may include: 

Geophysical surveys with hand-help equipment or pulled by ATV; 

“Mag and Dig” survey method where personnel will have handheld metal and other 

detectors and dig up contacts using hand tools such as shovels; 

MC sampling using hand held tools such as trowels, shovels, an/or hand augers; and, 

BIPs - In-place detonation of UXO/MEC too hazardous to move. 

Mitigation measures for these activities include driving any motorized vehicle used on site at 

a slow speed and digging only enough soil to uncover the contact or anomaly. In the event of 

BIPs, mitigation measures will include watering down area around the UXO/MEC to limit the 

amount of dust produced by the detonation. Other activities that may generate dust or 

emissions are traveling to and from the sites in the support vehicles. The survey crews will 

drive at speeds that minimize dust generation along the dirt roads in the MRS. 

6.5.4 Spill Control and Prevention 

All vehicle fueling and maintenance of project vehicles will be conducted off-site at paved 

and contained areas. If a severe leak of fuel or other vehicle fluids occurs the following 

procedures will be accomplished: 

Berm the fuel spill site with dirt so that the fuel or fluid does not spread; 

Apply oil-absorbing material to the spill (each vehicle will be equipped with a spill 

kit); 

Report the spill to the SUXOS immediately; and, 

Remove the contaminated soil and dispose in an approved landfill. 

6.5.5 Storage Areas and Temporary Facilities 

Storage areas and temporary facilities for logistic support will be located in off-site 

compounds that provide easy access to the project location. These sites will be utilized to 

store project equipment, such as vehicles, temporary offices for personnel and project 

management, dumpsters and roll-off bins for waste and UXO related material, and a secured 

area for the project explosive magazine. 
Work Plan Remedial Investigation/Feasibility Study 

Contract No. W912PL-09-D-0005 Bristol Project No. 410073 

August 2011 6-18 FINAL 

Mitigation measures such as temporary fencing, erosion control, and other site specific 

measures may be necessary if the project base is not within an existing secured compound. 

6.5.6 Access Routes 

Mitigation measures regarding access routes will be dependent upon the protected status of 

the site and the protected status of the surrounding environment. In general, field crews will 

travel to and from the site only on established roadways (dirt or paved), unless the site is 

within a designated wilderness area. Wilderness designation will require the field crews to 

leave the support vehicles outside the boundaries of the wilderness site and walk in to the site. 

All motorized equipment will be left outside the boundaries of these designated areas. 

6.5.7 Trees and Shrubs Protection and Restoration 

Vegetation removal (trees and/or shrubs) will not be performed during the RI. Minimal 

vegetation impacts will occur if a contact or anomaly is located below the ground surface at 

the base of a tree or shrub. Field crews will remove as little soil as necessary to access the 

contact while working around any vegetation. Vegetation will not be removed to allow 

transects to pass through the area. If a large amount of vegetation is encountered while 

performing a transect, the field crew will go around the vegetation, and the location of the 

vegetation will be noted in the field log and transect log. The crew will continue the transect 

once they have passed around the vegetation. 

6.5.8 Water Run-on and Run-off 

The RI/FS field investigation will not alter drainage patterns therefore no mitigation 

procedures are required to control water run-on or run-off. 

6.5.9 Decontamination and Disposal of Equipment 

The project does not involve chemicals or practices that require decontamination; therefore, 

this section is not applicable. Decontamination procedures related to MC sampling are 

included in the Appendix E, Sampling and Analysis Plan.

6.5.10 Minimizing Areas of Disturbance 

Efforts will be made to minimize any unnecessary disturbance within the MRS. Any 

disturbance to habitats required by field investigation activities will be carefully recorded and 

documented by the project biologist prior to ground disturbing activities. Photographs, 

drawings, or video recordings, and GPS readings will all be used to restore disturbed areas as 

close as possible to their original contours, soil strata, and compaction. 

6.5.11 Post-activity Cleanup 

Post-activity cleanup will be accomplished on a daily basis as field crews collect solid waste 

associated with lunch breaks and other daily breaks and remove them from the site. Solid 

waste will be disposed of in an approved off-site location. 

6.5.12 Air Monitoring Programs 

Air monitoring programs are not necessary and will not be implemented for the RI/FS.

Dear Mr. Lodge: 

Please find enclosed the 2016 Annual Groundwater Monitoring and Sampling, and Wet 

Weather Preparedness Report for former Sutter Avenue Landfill, located at Camp San Luis 

Obispo, California. The landfill is located in San Luis Obispo County. The Annual groundwater 

monitoring and sampling event and wet weather preparedness inspections were conducted at 

the landfill in 2016 to comply with the requirements of the Central Coast Regional Water Quality 

Control Board (CCRWQCB) General Monitoring and Reporting Program No. R3-2004-0006 for 

Post-Closure Maintenance of Closed, Abandoned or Inactive Nonhazardous Waste Landfills 

within the Central Coast Region, modified for the Sutter Avenue Closed Class III Landfill on 

July 5, 2007 (MRP). The June 8, 2015 modification to MRP calls for the annual groundwater 

sampling event to be performed in July; however, the sampling event was conducted on August 

4, 2016, in order to improve field scheduling efficiencies. Wet weather preparedness inspection 

reports and descriptions of maintenance activities are also included in the report as suggested 

in the June 8, 2015 modification. 

All groundwater analytical results are consistent with historical data. No violations were 

observed or reported since the last submittal. To the best of my knowledge the report is true, 

complete, and correct. If you have any questions, please contact me at (916) 419 - 7184. 

Sincerely, 

Luis Mercado, PG

1 INTRODUCTION 

In accordance with Agreement No. E0865, ECM Consultants (ECM) prepared this 2016 

Annual Monitoring and Sampling, and Wet Weather Preparedness Report for the 

California Army National Guard (CA ARNG) to document the annual groundwater 

monitoring and sampling results and the current condition of the former Sutter Avenue 

Class III Landfill (known henceforth as the “landfill”) (Figure 1) located at Camp San Luis 

Obispo in San Luis Obispo County, California. This report details the groundwater 

monitoring activities performed during the 2016 annual event completed by ECM. It also 

includes wet weather preparedness inspections and activities completed between 

October 1, 2015 and September 30, 2016. Landfill gas detection results are not presented 

in this report but can be found in the landfill gas monitoring reports submitted 

semiannually. 

Camp San Luis Obispo (CSLO) was established in 1928 as the original home of the CA 

ARNG. It was then known as Camp Merriam and originally occupied approximately 2,000 

acres of ranch land secured by the State of California on a lease-purchase basis. By 

1940, CSLO grew to 5,800 acres of state-owned land. CSLO was leased to the federal 

government between 1940 and 1947 for use as a military training facility during World 

War II, during which time the facility expanded to approximately 15,000 acres of both state 

and federal land. In 1947, the state-owned portion of the facility reverted to state control, 

and the federal land was “ceded to the state in lieu of restoration” (Ecology and 

Environment, Inc., 1991). In 1951, the U.S. Army opened its Southwest Signal Center at 

CSLO, where it trained soldiers during the Korean War. In 1953, part of CSLO remained 

under U.S. Army control in stand-by readiness as a military mobilization site. CSLO 

returned to state control on July 1, 1965 (England Geosystem, 2004). 

CSLO currently occupies approximately 5,320 acres and provides operational, training, 

and logistical support to a wide variety of civilian and military agencies at the federal, 

state, and local levels. Cuesta College, the California Men’s Colony, California 

Polytechnic State University at San Luis Obispo, and other state and local government 

agencies now occupy land that was formerly part of CSLO. Also, portions of the current 

facility are leased to other state agencies, such as the California Department of Forestry 

and the California Conservation Corps. 

1.1 Site History 

The Sutter Avenue Landfill is a 5.2-acre, closed Class-III landfill that was operated by the 

CA ARNG and is located on CSLO, a CA ARNG operated facility. The landfill is located 

in the southwest corner of CSLO and is bounded by Poison Oak Creek to the southwest, 

Sutter Avenue to the north, a former California Department of Transportation facility to 

the north and east, and privately owned range land to the south (Figure 2). The majority 

of waste-disposal activities in the general area of the landfill occurred between 1970 and 

1985, although a final cover system was not constructed until 1996-1997. 
2016 Annual GWM and WPP Report September 30, 2016 

Sutter Ave. Landfill Camp San Luis Obispo 

Page 2 of 17

A trench-and-cover waste-disposal method was used at the landfill. The trenches were 

reportedly approximately 200 to 300 feet long, 8 feet wide and 8 feet deep (State of 

California Military Department, 1976). Reportedly, the trenches were covered with at least 

6 inches of daily cover and a minimum of 2 feet of compacted earth as an interim cover. 

In addition, inspections of the disposal were conducted at a frequency of at least three 

times per week by the Facilities Engineer and monthly by the San Luis Obispo Division 

of Environmental Health (State of California Military Department, 1976; State of California 

Military Department, 1977; Geosystem Consultants, Inc., 1998). 

Records indicate that the type of waste material deposited at the Site consisted of the 

following: decomposable organic refuse (such as ordinary household, industrial, 

agricultural and commercial refuse), garbage and scrap metal (US Army Environmental 

Hygiene Agency, 1986; Staal, Gardner & Dunne, Inc. [SGD], 1989; Ecology & 

Environment, Inc., 1991). Reportedly, less than one half of the landfill’s original capacity 

of approximately 36,000 cubic yards was used (SGD, 1989; ERM-West, Inc., 2003). 

The final cover was constructed over the landfill in general accordance with a Central 

Coast Regional Water Quality Control Board (CCRWQCB)-approved final closure and 

post-closure maintenance plan (Geosystem Consultants, Inc., 1995). The final cover 

system consisted of a 24-inch-thick foundation layer, a 60-mil barrier layer of high-density 

polyethylene (HDPE) with flexible membrane liner (FML) texture on each side, a lateral 

drainage layer of non-woven polypropylene fabric and an 18-inch-thick vegetative cover 

layer. To minimize the volume of fill required, the cover was designed with 4 percent 

slopes and was “recessed” into the existing ground surface. A toe drain around the 

perimeter of the final cover was to serve the dual purpose of anchoring the HDPE FML 

and draining water transmitted through the lateral drainage layer (Geosystem 

Consultants, Inc., 1995). 

The former Sutter Avenue Landfill is fenced off, secured and not readily accessible to 

unauthorized personnel. In addition, warning notices are posted along the fence, 

indicating that the landfill is closed and that no wastes of any description should be 

deposited within the landfill boundary. 

In late August 2013, CA ARNG was notified that the United States Army Corps of 

Engineers (USACE) no longer considered the former Sutter Landfill to be a Formerly 

Used Defense Site and eliminated the funding for compliance efforts at the landfill 

previously conducted by Eco and Associates, Inc. (Eco) for calendar year 2013. Upon 

notification from USACE, CA ARNG completed a dry season landfill inspection on 30 

September 2013 and a full round of groundwater sampling in December 2013 to 

constitute the second semiannual monitoring event in accordance with the Monitoring and 

Reporting Program (MRP). 

From 2009 through the 2014 first semi-annual (1SA14) period, Eco was under contract 

to conduct groundwater monitoring to comply with MRP. During the period from August 
2016 Annual GWM and WPP Report September 30, 2016 

Sutter Ave. Landfill Camp San Luis Obispo 

Page 3 of 17

2014 through September 2015, Star Resources, Inc. (Star). conducted the groundwater 

sampling activities at the site. In February 2015, Star conducted the 2015 first semiannual (1SA15) groundwater monitoring and sampling activities at the landfill (Star, 

2015). 

On June 8, 2015, CA ARNG received notification from CCRWQCB that the MRP had 

been revised in order to keep in line with current landfill site conditions. The following 

changes were made to the MRP: 

 Reduction in sampling frequency for wells MW-1, MW-3, MW-6, MW-7, and MW-8 

from semi-annual to annual for measurement of groundwater elevations and 

MRP’s Table 1 field and laboratory parameters; 

 The Annual Monitoring Period changed from January 1 – December 31 to July 1 

– June 30; 

 The Report Due Date changed from January 31 to September 30. This revision 

allows CA ARNG to include the Wet Weather Preparedness Report with the 

Annual Groundwater Monitoring and Sampling Report; 

 Upgradient detection wells MW-2, MW-4, and MW-5 to be removed from the 

monitoring program and should be properly destroyed; 

 Wells MW-9 and MW-10 would only be sampled when volatile organic compounds 

are detected above the practical quantitation limits in well MW-6; and, 

 Passive gas vent wells V1 through V9 to be removed from the monitoring program 

and should be properly destroyed. 

The reduction in sampling frequency resulted completion of the second semiannual 2015 

sampling event in July 2015, instead of August 2015. Sutter Avenue Landfill activities 

completed prior to January 1, 2015 were reported in the Groundwater Monitoring and 

Sampling Report, 2014 Annual Summary (Star, 2015a). The event originally planned as 

the 2015 second semi-annual (2SA15) event was actually the annual 2015 event (Star, 

2015b). 

Between October 2015 and September 2016, CA ARNG conducted at a minimum, 

quarterly dry season (May 1 to September 30) landfill inspections, monthly wet season 

(October 1 to April 30) landfill inspections, and additional landfill inspections following 

each storm event that produced a minimum of 1 inch of rain within a 24-hour period. 

Monthly rainfall data was obtained from the Rancho de Caballo weather station 

KCASANLU47 located approximately 2.85 miles east of the landfill (see Section 2.2 for 

more information). 

Constituents of concern (COCs) listed in Table 2 of MRP that are not analyzed as part of 

the routine monitoring program are to be analyzed once every five years at each of the 

landfill monitoring points listed in MRP (see 40 Code of Federal Regulations [CFR], Part 

258). If there is an indication of release, then the monitoring must include the indicated 
2016 Annual GWM and WPP Report September 30, 2016

COCs. All existing wells were last sampled for COCs by Eco during the 1SA14 monitoring 

event completed on February 27, 2014.

1.2 Site Geology and Hydrogeology 

The Camp SLO area is located on Mesozoic metamorphic rocks of the Franciscan 

Formation, and undifferentiated Mesozoic ultramafic rocks (Society of Economic 

Paleontologists and Mineralogists [SEPM], 1982). The Franciscan Formation is a 

mélange consisting of a disordered arrangement of sandstone and associated shale, 

altered volcanic rocks, and lesser amounts of chert, serpentine, diabase gabbro, 

conglomerate, and blueschist facies metamorphic rocks (Hart, 1973). The Franciscan 

sandstone, which comprises a large portion of the formation, is a massive grayish-brown 

greywacke with little or no bedding. Studies of the geologic history and setting of the 

Franciscan Formation give evidence that the mélange was formed in the late Mesozoic 

in the subduction zone between continental and oceanic plates. 

Presently, the formation appears as small to large fault blocks ranging in size from a few 

inches to half mile in length. The fault blocks typically appear as rounded monoliths that 

stand out above a generally hummocky terrain (Hart, 1973). The Mesozoic ultramafic 

rocks that crop out in the area consist of serpentine and intrusive igneous rocks. The 

serpentine was derived from olivine and pyroxene-rich ultramafic rocks. Dark green and 

gray diabase is found intermingled with the serpentine. Recent alluvium is noted along 

modern stream channels, creeks, and similar tributaries. The Quaternary-aged alluvial 

deposits are composed of Franciscan-derived sediments (quartz, quartzite, serpentinite) 

and fine-grained sediment (Hart, 1973). 

The major structural features of the area are right-lateral, strike-slip faults having near 

vertical fault planes, which are generally three to five miles in length. The faults are 

believed to be associated with the Rinconada fault zone to the east. The faults truncate 

all the pre-Quaternary rocks in the area (Hart, 1973). 

The landfill is located in the southwest corner of CSLO, in a flat, low-lying area of the 

Poison Oak Creek valley between Cerro Romualdo and Conner Peak. The landfill is 

bounded by an unnamed tributary of Poison Oak Creek to the southwest. The landfill 

ranges in elevation from approximately 232 feet above mean sea level (amsl) on the east 

to 222 feet amsl on the west. It is underlain by Holocene-aged alluvial soils consisting of 

clay, silty clay, and sandy clay inter-bedded with sand and gravel derived from bedrock 

formations that flank the landfill.

The Mesozoic-age Franciscan Formation and associated ultramafic rocks (on which 

CSLO is located) are generally not recognized as water-bearing formations. Waterbearing formations relatively near to the site are found in the Los Osos Valley, a 20-

square mile coastal drainage basin composed of younger alluvium (Department of Water 

Resource [DWR] Bull. No. 118). The major portion of the drainage basin is located 2 to 3 

miles south of the landfill. 

Groundwater in the Los Osos Valley is found at depths of approximately 10 to 50 feet 

below ground surface (bgs). The water-bearing zone is estimated to extend to a depth of 

200 feet. The water from the Los Osos Basin has been extracted primarily for irrigation 

and municipal purposes. 

The groundwater flow direction beneath the Site is north-northwesterly along an unnamed 

tributary of Chorro Creek located between Cerro Romualdo and Conner Peak. 

Groundwater levels beneath the landfill fluctuate seasonally and yearly, and have ranged 

from approximately 5 to 24 feet bgs in well MW-8 (upgradient) to approximately 14 to 40 

feet bgs in MW-9 (downgradient). 

Cerro Romauldo is flanked by the Chorro Creek valley on the north. Chorro Creek flows 

westward through this valley to Morro bay. The flow of water in Chorro Creek is usually 

seasonal, but often flows year round. 

Chorro Creek and its tributaries flow down Cuesta ridge into CSLO. This watershed has 

been significantly disturbed by quarrying and mining, military maneuvers, and by the 1994 

Highway 41 fire (Cal Poly Land, 2016 and CA ARNG, 2014). 

2 GROUNDWATER MONITORING ACTIVITIES 

Activities associated with the 2016 annual monitoring event included the gauging of 

groundwater monitoring wells for depth to groundwater and the collection and analysis of 

groundwater samples. All sampling activities associated with the monitoring event were 

performed in accordance with the latest modified MRPs (No. R3-2004-0006), and ECM’s 

Site-Specific Health and Safety Plan (ECM, 2016). 

2.1 Groundwater Gauging and Sampling 

The seven groundwater monitoring wells currently being monitored as part of the revised 

monitoring and reporting program for the landfill include MW-1, MW-3, MW-6, MW-7, 

MW-8, MW-9, and MW-10. Well MW-8 is located in the southern (upgradient) part of the 

landfill. MW-1 and MW-3 are located along the northern (downgradient) edge of the 

landfill. Wells MW-6, MW-7, MW-9, and MW-10 are located downgradient and outside of 

the landfill boundaries (Figure 2). 

Formerly, groundwater monitoring and sampling was conducted on a semiannual basis 

(February and August). Per the June 8, 2015 revised MRP, groundwater monitoring and 

sampling occurs annually (July). Wells MW-9 and MW-10 are only sampled when volatile 
2016 Annual GWM and WPP Report September 30, 2016

Page 6 of 17

organic compounds (VOCs) are detected above the practical quantitation limits in well 

MW-6. Wells MW-2, MW-4, and MW-5 are no longer required to be sampled and will be 

properly destroyed in the future. 

Groundwater monitoring wells were gauged for depth to groundwater on August 4, 2016 

using an electric water level meter, and depths were recorded to the nearest 0.01 foot, 

relative to the top of the well casing. Groundwater elevations were calculated and are 

shown in Table 2 and on Figure 3. Results were recorded on groundwater monitoring 

gauging data sheets (Appendix A). A graphical representation of the groundwater 

elevations (hydrograph) can be found in Appendix B, and historical groundwater 

elevations and analytical data are presented in Appendix C. 

The wells were purged using low-flow (minimal-drawdown) purging methods and sampled 

using new tubing at each location and a bladder sampling pump. Field parameters 

including temperature, potential of hydrogen (pH), electrical conductivity (EC), turbidity, 

and dissolved oxygen (DO) were measured for stability during well purging. Purging 

continued until parameters stabilized in three or more successive readings as follows: 

 Temperature to within ±0.5 degrees Celsius (°C) 

 pH to within ±0.1 pH units 

 EC to within ±3 percent microsiemens per centimeter (μS/cm) 

 Turbidity to less than 5.0 Nephelometric Turbidity Units (NTU), desired; however, 

it is not critical to reach this parameter prior to sampling 

Well purging data is recorded on groundwater monitoring well sampling forms 

(Appendix A). 

One trip blank, one blind field duplicate sample, and one equipment rinsate blank were 

submitted for laboratory analysis. The trip blank was prepared by the laboratory and 

remained with the samples and cooler through the sampling event. The blind field 

duplicate sample was collected from one groundwater monitoring well for quality 

assurance/quality control (QA/QC) purposes. 

Purge water from groundwater monitoring well sampling activities was placed in a labeled 

55-gallon drum and stored near Building FMS #19 at Camp San Luis Obispo, per 

indications from the Directorate of Public Works (DPW), pending waste characterization 

and eventual off-site disposal. 

2.2 Groundwater Sample Analysis 

The groundwater samples were transported under chain-of-custody protocols to BC 

Laboratories, Inc. (BC Labs) in Bakersfield, California. BC Labs is accredited by the State 

of California under the Environmental Laboratory Accreditation Program (ELAP #1186) 

to perform the specified analyses. Groundwater samples from wells MW-1, MW-3, MW-6, 

MW-7, MW-8, MW-9, MW-10 were analyzed for the following constituents: 
2016 Annual GWM and WPP Report September 30, 2016 

Sutter Ave. Landfill Camp San Luis Obispo 

Page 7 of 17

 Volatile organic compounds (VOCs) by U.S. Environmental Protection Agency 

(EPA) Method 8260B. 

In addition, groundwater samples from wells MW-1, MW-3, MW-6, MW-7 and MW-8 were 

analyzed for the following constituents: 

 General Chemistry Analysis: 

o Nitrate as nitrogen (N), Sulfates, and Chloride by EPA Method 300.0, and 

o Total dissolved solids (TDS) by EPA Method 160.1 

Additionally, the trip blank and equipment blank were analyzed for VOCs by EPA Method 

8260. The blind field duplicate sample, labeled QCBD, was collected from monitoring well 

MW-6. The field duplicate was analyzed for VOCs and general chemistry parameters per 

the EPA methods listed previously. 

3 GROUNDWATER MONITORING RESULTS 

On August 4, 2016, ECM conducted the 2016 Annual Monitoring and Sampling event. 

Groundwater samples were collected from wells MW-1, MW-3, MW-6, MW-7, MW-8, 

MW-9, and MW-10. Monitoring well completion details are presented in Table 1. 

Groundwater data for the 2016 Annual Monitoring and Sampling event are summarized 

in Tables 2 through 6. 

3.1 Groundwater Elevation and Gradient 

Depth to groundwater measurements ranged from approximately 16.77 feet bgs in well 

MW-8 to 34.11 feet bgs in well MW-9. Groundwater elevations in the gauged monitoring 

wells increased between July 2015 and August 2016. Elevation increases ranged from 

1.54 feet in well MW-1 to 6.53 feet in well MW-8. Average groundwater elevation across 

the landfill area was 199.27 feet amsl. Table 2 summarizes the depth to water 

measurements collected during the 2016 Annual monitoring event. A table summarizing 

historical groundwater elevation data since April 2005 is presented at Table C-1 in 

Appendix C. 

Consistent with previous groundwater monitoring event observations, the apparent 

groundwater flow direction during the 2016 Annual Monitoring and Sampling event was 

generally toward the north-northwest (Figure 3). The gradient ranged from approximately 

0.0139 feet per foot (ft/ft) in the southern area of the Site, to 0.0106 ft/ft in the northern 

area of the Site. 

3.2 Groundwater Analytical Results 

The groundwater sample results for VOCs, general chemistry, and field parameters are 

discussed in the following sections. Historical groundwater quality data for all sampling 

events are summarized in Appendix C, Tables C-2 through C-4. Analytical laboratory 

reports are provided in Appendix D.

3.2.1 Volatile Organic Compounds 

Carbon tetrachloride was detected in well MW-6 and its field duplicate (0.76 micrograms 

per liter [μg/L] and 0.70 μg/L, respectively), which are above the California EPA Maximum 

Contaminant Level (MCL) of 0.5 μg/L. Chloroform was detected in MW-6 and its field 

duplicate (3.5 μg/L and 3.4 μg/L, respectively), which are below the MCL of 80 μg/L. For 

this event, carbon tetrachloride and chloroform concentrations were reported above their 

respective PQLs. Per the revised MRP, samples collected from wells MW-9 and MW-10 

were analyzed for VOCs after the detections at well MW-6 had concentrations above 

applicable PQLs were reported by the laboratory. No other VOCs, including methyl 

tertiary butyl ether (MTBE) and 1,4-dioxane, were detected in any of the groundwater 

samples, including wells MW-9 and MW-10. Analytical results for VOCs are summarized 

in Table 3 and historical 1,4-dioxane results are presented in Table 4. Historical analytical 

results for VOCs are presented in Table C-2 of Appendix C. 

3.2.2 General Chemistry Parameters

4 SUMMARY OF GROUNDWATER MONITORING RESULTS 

The results from CSLO former Sutter Avenue Landfill groundwater monitoring event are 

summarized below: 

 Seven groundwater monitoring wells (MW-1, MW-3, MW-6, MW-7, MW-8, MW-9, 

and MW-10) were sampled during the 2016 Annual monitoring and sampling 

event. 

 Groundwater elevation increased across the site between July 28, 2015, and 

August 4, 2016, with an average groundwater elevation increase of 3.66 feet for 

the seven monitored wells. Consistent with previous groundwater monitoring 

events, the apparent groundwater flow direction was generally toward the northnorthwest. The groundwater gradient ranged from approximately 0.0139 ft/ft in the 

southern area of the landfill, to 0.0106 ft/ft in the northern area of the landfill. 

 Carbon tetrachloride was detected in well MW-6 and its field duplicate at 0.76 μg/L 

and 0.70 μg/L, respectively, which are above MCL of 0.5 μg/L. 

 Chloroform was detected in MW-6 and its field duplicate at 3.5 μg/L and 3.4 μg/L, 

respectively, which are below the MCL of 80 g/L. 

 TDS was detected above MCL of 500 mg/L in three wells (MW-1, MW-3 and MW-8) 

with a maximum concentration of 1,100 mg/L at well MW-1. 

 Nitrate as N, sulfate, and chloride concentrations were detected below their MCLs 

in all wells. 

 Field parameters included pH, EC, temperature, turbidity, and DO. The recorded 

values of these parameters were found to be consistent with historical data.

5 QUALITY ASSURANCE AND QUALITY CONTROL 

QA/QC activities for the 2016 Annual Monitoring and Sampling event were conducted in 

accordance with MRP. Field QA/QC measures included the collection and analyses of 

the following samples: 

 Field duplicate groundwater samples at 10 percent frequency or greater 

 One trip blank sample per sample container 

 One equipment rinsate blank 

Field duplicate samples are collected and analyzed as an indication of overall precision. 

These analyses measure both field and laboratory precision. Trip blanks are used to 

evaluate representativeness by identifying any VOCs that may have been introduced to 

the environmental samples during shipment, handling, or storage onsite and at the 

laboratory. Rinsate blanks are collected to indicate whether reusable equipment is 

properly decontaminated between wells. Note that new tubing was used for each well. 

Laboratory QA/QC procedures were carried out according to EPA Method specifications 

and data was accepted based on QA/QC criteria established by the EPA. Laboratory 

QA/QC procedures included analysis of the following samples: 

 Method blanks 

 Matrix spike and matrix spike duplicate (MS/MSD) 

 Laboratory control sample and laboratory control sample duplicate (LCS/LCSD) 

 Post-digestion spike and duplicate 

 Laboratory duplicate 

 Surrogate spike 

5.1 Groundwater Sampling Event QA/QC Results 

For the analysis of groundwater samples, one field duplicate sample was collected: 

Sample QCBD was collected at well MW-6 approximately 40 minutes prior to collection 

of the primary sample. The reported analytical results of the field duplicate were very 

similar to the primary sample with an estimated relative percentage difference (RPD) of 

8% for carbon tetrachloride and 3% for chloroform. 

Field blank samples included one trip blank sample (QCTB) that was analyzed for VOCs. 

No VOCs were detected in the trip blank sample, indicating that there was no cross 

contamination of VOCs in groundwater samples during transportation of samples to the 

laboratory. 

Once sampling was completed, an equipment blank sample was collected (QCEB) and 

analyzed for VOCs. VOCs constituents were not detected in the equipment blank sample.

A laboratory method blank was analyzed for VOCs. No VOCs were detected in the 

method blank (Appendix D). 

6 WET WEATHER PREPAREDNESS LANDFILL OBSERVATION AND 

MAINTENANCE 

The wet weather preparedness section of this report will address items of concern at the 

landfill, including the soil cover, cap, and drainage of the landfill. Areas of concern and 

recommended repairs are provided below. Preparedness actions should be completed 

by DPW prior to September 30, 2016 in order to maintain compliance with the June 8, 

2015 modified General MRP No. R3-2004-0006. In accordance with Waste Discharge 

Requirements, maintenance and repairs are required to “minimize rainfall infiltration, 

prevent ponding, resist erosion or flooding of the landfill, and to prevent surface drainage 

from contracting or percolation through wastes.” These actions are reported in this Wet 

Weather Preparedness Report. 

Inspections of the former Sutter Avenue Landfill occurred monthly during the wet season 

(October 1 through April 30) and quarterly (twice) during the dry season (May 1 through 

September 30). 

6.1 Sutter Avenue Landfill 

ECM completed dry season inspections on June 15 and August 5, 2016, to determine the 

current state of the landfill and landfill drainages, the landfill perimeter, and possible 

receiving waters. A Wet Weather Preparedness Assessment Plan was prepared by ECM 

detailing maintenance actions recommended to ensure the landfill is adequately prepared 

for the rainy season. This report was submitted to CA ARNG on August 31, 2016 to allow 

DPW time to complete the landfill maintenance work prior to the rainy season. 

6.1.1 Soil Cover and Landfill Cap 

The landfill cap and the immediately surrounding areas are occupied with animal burrows 

(Photographs 1 through 4 in Appendix E). Some of the burrows are very large in size 

creating areas where water can pool in a rain event. These items will be corrected through 

the replacement of the landfill cap, which already has been contracted by CSLO in the 

related Landfill Corrective Action Work Plan (Tetra Tech, 2016) which is in progress and 

tentatively approved by CCRWQCB. This field procedure is planned to be started during 

the construction season of 2017. 

Removal of large plant growth and trash from the drainage on the west side of the landfill 

(Photograph 5 in Appendix E) will be completed by a DPW work crew under word order 

#SL2016-001098, following the approval of a Project Information Package (PIP) through 

the CSLO Environmental Conservation Office, and the scheduling of the plant and trash 

removal itself. 
2016 Annual GWM and WPP Report September 30, 2016 

Sutter Ave. Landfill Camp San Luis Obispo 

Page 12 of 17

Removal of the accumulation of cut plant material from the base of the fence at the 

southwest corner of the landfill (Photograph 6 in Appendix E), at its entry to Poison Oak 

Creek will be completed by a DPW work crew under work order #SL2016-001095, 

following scheduling. This work may be done at the same time as the plant and trash 

removal required above. 

Replacement or repainting of warning sign advising of the location of the solid waste 

landfill and advising no trespassing through the landfill (Photograph 7 in Appendix E), as 

located on the fence line along Sutter Avenue will be performed by DPW sign painting 

trade under work order #SL2016-001096, following scheduling of this work. 

Replacement and repair of damaged barb wire along the Sutter Avenue fence of the 

landfill (Photograph 8 in Appendix E), both south and north of the warning sign in the 

previous item, will be performed by a DPW work crew under work order #SL2016-00197, 

following scheduling and the ordering of replacement barb wire fencing. 

Repair or replacement of the cyber lock on the Sutter Avenue Landfill gate, located at the 

northeast corner of the landfill (Photograph 9 in Appendix E), will be done by DPW 

locksmith trade under work order #SL2016-001098, following scheduling and possibly the 

purchase of a replacement cyber lock, if required. 

With the exception of the animal burrows to be fixed with the replacement of the land cap, 

it is expected that the correction of the listed items will be completed by November 1, 

2016. 

6.1.2 Drainage 

The concrete v-ditches along the entire northern northeastern boundary should be 

cleared of soil (Photograph 1 in Appendix E). This soil gets washed into the drainage 

system downstream. The burrows along the concrete v-ditches should be eliminated to 

prevent the loose soil from washing back into the v-ditch during the next storm and to 

minimize rainfall infiltration. 

Before and after the replacement of the landfill cap, CA ARNG should consider options 

for decreasing the burrowing animal population. Currently, there are owl boxes located 

along the western boundary of the landfill. These owl boxes should be repaired or 

replaced to encourage use by natural predators to reduce the burrowing animal 

population at the landfill. The raptor boxes should be cleaned and the posts should be reset. A couple of the posts appear to be bent and should be replaced and then reinstalled. 

Installation of additional raptor perches in the landfill would be beneficial, as there are no 

other areas for raptors to perch and hunt. 

The CA ARNG and DPW are completing repairs related to the above-mentioned concerns 

at the time of issuance of this report. Work should be completed by November 1, 2016; 

however, ongoing work at the landfill should continue to ensure the landfill is ready for a 
2016 Annual GWM and WPP Report September 30, 2016

large rain event. Additional photographs showing the landfill after maintenance activities 

can be requested from the CA ARNG. 

6.2 Rainfall Summary 

Historical data obtained from the Internet site “www.wunderground.com” was used to 

determine precipitation totals for the 2015 - 2016 period. Historical weather data 

presented in the previous report (Star, 2015b) were obtained from weather station Cuesta 

College KCASANLU17, located approximately 2,500 feet northwest of the landfill, 

however, when consulted by ECM this station only had data available through March 9, 

2016. In the interest of obtaining a complete set of annual historical weather data for the 

current report, data were obtained from weather station Rancho de Caballo 

KCASANLU47, located approximately 2.85 miles east of the landfill. Historical weather 

data were obtained for the period October 1, 2015 through September 29, 2016; data 

were not obtained for the September 30, 2016 due to time requirements involved in 

preparation of this report. 

Quarterly precipitation totals are as follows: 

 October - December 2015 6.19 inches 

 January – March 2016 19.35 inches 

 April - June 2016 0.50 inches 

 July - September 2016 0.00 inches 

The heaviest 24-hour rainfall from October 2015 through December 2015, occurred on 

November 2, 2015 (1.09 inches). The heaviest 24-hour rainfall from January 2016 through 

March 2016, which had the most rain out of all the quarters, occurred on March 5, 2016 

(3.01 inches). The heaviest 24-hour rainfall from April 2016 through June 2016, occurred 

on April 8, 2016 (0.38 inches). For the period July 2016 through September 2016, there 

was no recorded rainfall. The rainfall history for the 2015-2016 wet season is depicted on 

rainfall data logs provided in Appendix G. 

There was one storm event with precipitation greater than one inch in 24-hours during the 

October 2015 through December 2015 period. As indicated previously, it occurred on 

November 2, 2016 (1.09 inches). 

There were seven storm events with precipitation greater than one inch in 24-hours during 

the January 2016 through March 2016 period as follows: 

 January 5, 2016 - 2.08 inches; 

 January 6, 2016 - 1.1 inches; 

 January 19, 2016 - 2.56 inches; 

 January 31, 2016 - 1.83 inches; 

 February 17, 2016 - 1.17 inches; 

 March 5, 2016 - 3.01 inches; and, 

 March 7, 2016 - 1.9 inches. 
2016 Annual GWM and WPP Report September 30, 2016

Page 14 of 17

There were no storm events with precipitation greater than one inch in 24-hours during 

the May 2016 through June 2016 period and July 2016 through September 2016 period. 

Star completed wet weather inspections after these rain events. The inspection forms are 

included in Appendix F. 

7 SUMMARY OF GROUNDWATER MONITORING AND WET WEATHER 

PREPAREDNESS ACTIVITIES 

In accordance with the revised MRP No. R3-2004-0006, a summary of events that 

occurred in the 2016 monitoring year is to be submitted as part of the annual report. The 

following sections fulfill this requirement. 

7.1 Analytical Results 

On August 4, 2016, groundwater monitoring and sampling was conducted at the former 

Sutter Avenue Landfill. The monitoring program includes groundwater monitoring wells 

MW-1, MW-3, MW-6, MW-7, MW-8, MW-9, and MW-10. 

Carbon tetrachloride was detected in well MW-6 at 0.76 μg/L, above its respective MCL 

of 0.5 μg/L. Chloroform was detected in well MW-6 at 3.5 μg/L, below its respective MCL 

of 80 μg/L. All other VOC concentrations were reported below their respective MCLs and 

mostly below the laboratory reporting limits. 

TDS exceeded its MCL of 500 mg/L at wells MW-1, MW-3, and MW-8. Concentrations of 

chloride, nitrate as N, and sulfate did not exceed their MCLs in any wells. 

All laboratory analytical results can be found in Appendix D. 

7.2 Overall 2016 Compliance Summary 

The former Sutter Avenue Landfill has been properly inspected and prepared for the 

upcoming rainy season. Monthly inspections were performed during the rainy season 

(October 1 through April 30), and quarterly inspections were performed during the dry 

season (May 1 through September 30). Key concerns included erosion control measures, 

animal burrowing control measures, controlling vegetation, and maintaining integrity of 

the compacted soil cover before replacement. DPW will continue to conduct maintenance 

activities at the landfill as necessary. 

The detection monitoring events performed in 2016 complied with all current CCRWQCB 

and CalRecycle requirements and the revised MRP related to subsurface groundwater 

and landfill gas monitoring. Landfill gas results are reported under a separate cover. 

The results for the 1SA16 detection monitoring event indicated no significant groundwater 

impacts. The results for the 2SA16 detection monitoring event also indicated no 

significant groundwater impacts. Per the MRP schedule, COC monitoring was not 

conducted during this period; however, the next COC monitoring event will be completed 

during the annual event in 2019.

symptoms persist seek medical attention.

Eyes: Rinse with plenty of water for at least 15 minutes. Seek medical attention.

Ingestion: If the patient is conscious have him rinse his mouth with water, spit it out and 

then have him drink water. Seek medical attention. Occurance of symptoms 

may be delayed.

Information for doctor: If injured skin is contaminated on a large scale apply polehtylene glycol (e. g. 

Lutrol, PEG 400), leave it on for some minutes and then wash with water.

SAFETY DATA SHEET

Safety Data Sheet according to FIRST VALUE HOLDINGS Ltd.

1907/2006/EC (REACH), Article 31 and Annex II

Product name: FireAde 2000 - Fire Fighting Agent

Date of issue: 12 Sept. 2008

Date of last revision: Page 4/ 10

Explanations:

- BLV: Biological limit value

- Remarks:: H : Substances effective by resorption through skin

S = Sensitizing substance

Y or C: There is no teratogenic risk if the exposure limit value and 

the BLV are maintained.

8.3 Personal Protection:

Adjust personal protective equipment to the type of burning materials. Use a fine dust respirator at 

least. Use eye protection if handling the concentrate.

The following protection measures apply to the product upon delivery (concentrate).

Respiratory protection: If aerosols are generated use fine dust respirator (P2 or P3) or a

ventilated breathing hood.

Hand protection: If contact with hands cannot be avoided use protection gloves tested

according to DIN EN 374. Seek advice from manufacturers of

protection gloves. If gloves cannot be used for safety reasons (e. g.

while working at rotating machines) use skin-protective barrier

cream. Consult the company medical officer for the type of barrier

cream to be used.

Comment: In contrary to the European ordinance 1907/2006/EC

(REACH), it is not sufficient to specify only the protective glove

material. The break-through-times are dependent not only on the

material but also on the manufacturing technique. It is therefore

essential to consult the manufacturers of protective gloves. For this

product rubber or plastic gloves are generally sufficient.

Eye protection: Safety glasses with side shield.

Skin protection: Use waterproof protective clothing and gumboots if contamination 

of clothing cannot be avoided.

General protective measures: Avoid contact with eyes and skin. Change contaminated clothing 

immediately.

Industrial hygiene: Do not eat, drink, smoke or take snuff at work.

EXECUTIVE SUMMARY

TC5326782.2s EXECUTIVE SUMMARY 7

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

STANDARD ENVIRONMENTAL RECORDS

State- and tribal - equivalent CERCLIS

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields

Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which

there may be reasons to investigate further. The database includes the following site types: Federal

Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State

Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information

that was available in CalSites, and provides additional site information, including, but not limited to,

identification of formerly-contaminated properties that have been released for reuse, properties where

environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk

characterization information that is used to assess potential impacts to public health and the environment at

contaminated sites.

 A review of the ENVIROSTOR list, as provided by EDR, and dated 01/30/2018 has revealed that there is

 1 ENVIROSTOR site within approximately 1 mile of the target property.

SEMS: Superfund Enterprise Management System

SEMS (Superfund Enterprise Management System) tracks hazardous waste sites, potentially hazardous waste sites,

and remedial activities performed in support of EPA’s Superfund Program across the United States. The list was

formerly know as CERCLIS, renamed to SEMS by the EPA in 2015. The list contains data on potentially hazardous

waste sites that have been reported to the USEPA by states, municipalities, private companies and private persons,

pursuant to Section 103 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This dataset also contains sites which are either proposed to or on the National Priorities List (NPL) and the

sites which are in the screening and assessment phase for possible inclusion on the NPL.

SEMS-ARCHIVE: Superfund Enterprise Management System Archive

TC5326782.2s Page GR-2

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under

the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP,

renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while

it is archived if site conditions change and/or new information becomes available. Archived sites have been removed

and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge,

assessment at a site has been completed and that EPA has determined no further steps will be taken to list the

site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or

other considerations require a recommendation for listing at a later time. The decision does not necessarily mean

that there is no hazard associated with a given site; it only means that. based upon available information, the

location is not judged to be potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites

Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence

or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these

properties takes development pressures off of undeveloped, open land, and both improves and protects the environment.

Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields

grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on

Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from

Cleanups in My Community. Cleanups in My Community provides information on Brownfields properties for which information

is reported back to EPA, as well as areas served by Brownfields grant programs.

EPA WATCH LIST: EPA WATCH LIST

EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement

matters relating to facilities with alleged violations identified as either significant or high priority. Being

on the Watch List does not mean that the facility has actually violated the law only that an investigation by

EPA or a state or local environmental agency has led those organizations to allege that an unproven violation

has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged

violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and

local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action

Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe

contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but

have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance

for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program

Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing

industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances

to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects

of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative

accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee

training measures; and Emergency response program that spells out emergency health care, employee training measures

and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

by the DTSC. The annual volume of manifests is typically 700,000 - 1,000,000 annually, representing approximately

350,000 - 500,000 shipments. Data are from the manifests submitted without correction, and therefore many contain

some invalid values for data elements such as generator ID, TSD ID, waste category, and disposal method. This

database begins with calendar year 1993.

EDR HIGH RISK HISTORICAL RECORDS

EDR MGP: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.
