Revised Work Plan for Excavation and Disposal of Ash and Debris

Gateway Lake Area

Ellsworth Air Force Base, South Dakota

1.0 INTRODUCTION

This work plan has been developed for the excavation of ash and debris buried near Gateway

Lake, within Ellsworth Air Force Base (EAFB), South Dakota. The purpose of the plan is to

define the limits of the debris area requiring excavation, to characterize the waste, and to

present disposal requirements. This work is being performed by EAFB as a voluntary action.

1.1 SITE LOCATION AND HISTORY

The Gateway Lake Area Site (Site) is located in the south central portion of EAFB. The Site is

bounded on the north by recently planted trees and on the east by an unnamed creek. To the

west is the entrance road to the Base's wastewater treatment plant, which adjoins the Site's

south boundary. Figure 1 shows the Site's location within EAFB and Figure 2 shows a site plan

with boundaries and topography.

The Site is located in a low-lying area approximately 400 feet south of Gateway Lake and north

of the Base's wastewater treatment plant. The terrain is open and grassy. The Site slopes

downward from 3,128 feet (NGVD) along the western boundary to 3,118 feet along its eastern

boundary.

To the north and east of the Site, grass- and brush-covered land continues to slope downward

to a creek. To the west, the land surface rises rapidly while more level terrain associated with

the treatment plant extends to the south.

The Site was under consideration for the construction of a new building. Two exploratory

geotechnical soil borings were advanced in August 2002 and encountered ash, debris, and

glass material. Because the presence of that material raised concerns that buried debris of

environmental concern might be present, there are no current plans to build on the Site.

Further evaluation of the Site's historical land use was conducted. An August 1946 aerial

photograph from EAFB files indicated a portion of the Site was once an open ravine extending

through the Site in an east-southeast direction and ending at the present day creek bed.

Evidence of filling within the ravine was also indicated. Further to the south, EAFB personnel

identified a former incinerator with roads connecting the incinerator to the ravine area,

suggesting the incinerator was a potential source of the ash and debris.

The Site has apparently been graded since the ravine is no longer evident. A portion within the

fenced boundary of the wastewater treatment facility has also been seeded with grass. Except

for recently planted trees to the north, the remaining area of the Site has been covered with

natural grass and shrubs.

A field investigation, which assessed the areal extent of buried debris, was conducted by

Earth Tech, Inc. (Earth Tech), and documented in a technical memorandum entitled

"Electromagnetic Survey and Soil Analysis - Gateway Lake Area, January 2003 (Revised

August, 2003)." A copy of the technical memorandum is attached as Appendix A. Based on the

electromagnetic survey results, a map depicting the area of buried ash and debris is provided in

Figure 3.

1.2 ORGANIZATION OF WORK PLAN FOR EXCAVATION AND DISPOSAL OF

ASH AND DEBRIS

This work plan is organized as follows:

• Section 2.0 presents a description of the debris removal and disposal tasks.

• Section 3.0 presents the documentation requirements and schedule.

• Section 4.0 presents Health and Safety requirements.

Implementation of these activities in accordance with this work plan, followed by documentation

of the excavation and disposal of the ash and debris in a subsequent Implementation Report,

will provide the basis for a "no further action" determination at the site.

2.0 ASH DEBRIS EXCAVATION AND DISPOSAL TASKS

Based on the results of the electromagnetic survey and soil borings, an area of approximately

'YJ acre is underlain by a mixture of soil, ash, and debris to a depth of 6 to 7.5 feet and is

typically encountered within 1 foot of the surface. Additionally, anomalous conductivity data and

soil boring information determined that concrete debris with some steel reinforcement bar is

included in the debris. Based on approval from the Rapid City Landfill (Appendix B),

approximately 3,000 cubic yards (4,500 tons) of material is expected to be removed and

transported to the landfill.

The following works tasks are required for the removal of the ash and buried debris:

1. Health and Safety Plan preparation (see Section 4.0).

2. Disposal approval.

3. Utility clearance and dig permit preparation.

4. Fence removal and replacement.

5. Waterline protection.

6. Excavation, transportation, and disposal of buried ash and debris.

7. Confirmation sampling to determine whether all waste material has been excavated.

8. Backfill and compaction.

9. Site restoration.

2.1 DISPOSAL APPROVAL

Analytical results of samples obtained during the electromagnetic survey and soil boring

investigation (Appendix A) were submitted to Solid Waste Operations, City of Rapid City, on

October 20, 2005, to determine if the material could be accepted and used as daily cover at the

Rapid City Landfill. The Supervisor of Landfill Operations subsequently requested additional

analytical results. A TCLP test for 2,4 dinitrotoluene was requested to determine if the

compound's concentration was within permitted levels. Additionally, total

petroleum hydrocarbon (TPH) as gasoline and diesel were requested to determine if the

material could be used as daily cover.

Earth Tech collected a supplemental debris sample on November 1, 2005, from a depth of

3 to 6 feet adjacent to soil boring SB02GW01 B using a mini-excavator. A sample was

submitted to Severn Trent Laboratories in Denver, Colorado, for TCLP analysis of

2,4 dinitrotoluene. A sample was also submitted to MidContinent Laboratories in

Rapid City, South Dakota, for TPH as diesel using EPA Method 8015B-S, TPH as gasoline

using EPA Method 8015-S, and benzene, toluene, ethylbenzene, and xylenes (BTEX), and

Based on these results, the Rapid City Landfill indicated that the material was acceptable and

could be used as daily cover. However, to be sure there are no additional requirements or

changes prior to starting excavation activities, the contractor responsible for disposal will

verify/receive written acceptance for disposal of the debris and submit documentation of same

to Ellsworth AFB.

If the excavated material is a light ash susceptible to blowing by the wind, the landfill will not be

able to accept it on windy days. The contractor will be responsible for minimizing dust

generation at the Site and shall be prepared for implementing dust mitigation techniques to

include delaying excavation, covering stockpiles, wetting, etc.

2.2 UTILITY CLEARANCE AND DIG PERMIT PREPARATION

Utilities within the work will be identified and located prior to excavation activities. A Base Civil

Engineering Work Clearance Request AF Form 103 (Dig Permit) will be completed prior to work.

2.3 FENCE REMOVAL AND REPLACEMENT

The 6-foot chain link fence located on the western, northern, and eastern sides of the proposed

excavation area will be removed and stored to allow access to the impacted materials.

Following completion of the work, the fence will be re-installed. During the excavation work,

orange construction fence will be installed to prevent unauthorized entry into the work area.

2.4 WATER LINE PROTECTION

A water line, approximately 6 to 8 feet deep, is routed north-south along the western fence and

then turns east following the northern fence line. The water line is located approximately 6 feet

north of the fence along the northern edge of the Site, which is approximately the northern edge

of the proposed excavation. The water line will be protected from settling or freezing during

excavation activities. Any bedding material removed during excavation will be replaced and

compacted as appropriate. The water line will be backfilled with a minimum depth equal to its

original depth.

Ellsworth Air Force Base. South Dakota

2.5 EXCAVATION, LOADING, AND TRANSPORTATION

Prior to beginning excavation activities, a silt fence will be installed downgradient of the

proposed excavation to control erosion. Buried debris will be excavated and disposed off-site.

Excavation is expected to extend to approximately 7.5 feet below grade and to follow the

contours of the former ravine into which the ash and debris were deposited (see Figure 4 for

approximate areal extent). The extent of vertical excavation will be field-determined by the

Base's on-site representative or as directed by the Owner's representative with a target depth of

at least 2 inches below the ash and debris layer.

A field photoionization detector (PID) will be available during the excavation work for the Base's

on-site representative to check for petroleum or other volatile organics if odorous material is

encountered. Excavated material with headspace measurements above 100 ppm as

isobutylene will be sampled and submitted for laboratory VOC analysis, then segregated until

the lab results are available and disposal requirements are confirmed or established. One

sample will be collected and analyzed for every 50 cubic yards of excavated, segregated

material.

Excavated material suitable for backfilling will be stockpiled for later use as backfill. Grading will

be done as required to prevent surface water from flowing into the excavation.

Ash and debris will be loaded directly into trucks for transportation to the landfill. Care will be

taken that no material is spilled on the roads or outside of the loading area. Trucks will be

tarped to prevent material from blowing out of the trucks. Weight tickets will be submitted to the

Base's representative daily.

2.6 CONFIRMATION SOIL SAMPLING

It is recommended that six samples be collected from the base of the excavation from a depth of

0-6 inches for SVOC analysis. The sample locations will be determined in the field. If the ash

material appears to be homogenous, samples will be collected to spatially represent the

excavated area as shown in Figure 4. If the ash/waste debris shows variability throughout the

excavation or the base of the excavation shows visual signs of contamination, the sample

locations may be adjusted to target areas of concern.

During excavation activities, a field VOC detector will be used to monitor the excavated

materials. If VOCs are detected, the analyte list for the samples will be expanded to include

VOCs.

Results will be compared to the USEPA Region 3 Risk Based Concentrations (RBCs), using the

April 7, 2006, update. Since the area will be backfilled, the industrial RBC for dermal and

inhalation risk will not apply. Results will be compared to the dilution attenuation factor (OAF) of

20 for evaluating the soil to ground water migration pathway. A rush analytical turnaround time

(3 days) will be used to minimize the time between excavation activities and backfilling of the

excavation. Analytical procedures will follow those presented in the Department of Defense

Quality Systems Manual for Environmental Laboratories dated January 2006.

2.7 BACKFILLING AND COMPACTION

Surrounding soils to the west and south of the excavation area will be re-graded to provide

backfill material. Additional backfill material is available on the southwest side of the runway.

The Base's representative will determine final grade. Backfill soils will be installed in 8-inch lifts

and compacted to 85 percent maximum density if backfill is cohesive or 90 percent if material is

cohesionless.

2.8 SITE RESTORATION

Following backfilling activities, the Site will be graded so that surface water drainage follows

previously existing grades. Rocks larger than 3 inches in any direction will be raked from the

upper surface of the soils. The disturbed area will be seeded by drill seeding. Watering will be

performed until and as needed to obtain an even growth of 2 inches.

3.0 DOCUMENTATION

The excavation work will be documented through a series of daily field logs that will be

completed by the Base's on-site representative to record all significant activities occurring at the

Site. The daily field log will include information regarding quantities of material excavated,

number of truck loads generated, waste manifest numbers generated each day, workers on-site,

problems encountered, etc. Copies of the daily field logs will be provided to the Base's

representative as a means of communicating and documenting the progress of the work at

the Site. Weekly summaries of the fieldwork performed may also be prepared to communicate

with regulatory agencies of any significant developments during construction.

Soil or wastes that are transported off-site for disposal will be documented by attaching copies

of truck tickets to verify volume of material transported, and by attaching records from disposal

facilities of volumes or weight of materials received, processed, or disposed. Field personnel

will track this documentation on a daily basis and the results of the work will be compiled upon

completion into an Implementation Report.

An Implementation Report will be prepared to document the results of the excavation work. The

Implementation Report will include:

• Scaled drawing of the work location.

• Sample locations, if needed.

• Laboratory analysis reports, if needed.

• Photographs.

• Pertinent observations and notes of the field staff during excavation.

• Dimensions and locations of excavated areas.

• Soil disposal quantities.

• Soil disposal facility locations.

• Waste manifests.

• Daily field logs.

• Confirmation sampling results, if needed.

4.0 HEALTH AND SAFETY

Due to the presence of SVOCs and arsenic above the RBC screening levels and the physical

hazards of soil excavation and trucking, the excavation work must be conducted within the

framework of a Site Specific Health and Safety Plan. The Contractor will be responsible for the

safe performance of its assigned services by its employees and/or subcontracted service

providers and implementation of any appropriate/required written health and safety

documentation. All work will be performed in accordance with applicable federal, state, and·

local regulations governing health and safety.

The Contractor will take all reasonable steps and precautions to prevent accidents and/or

injuries to site personnel, visitors, or the surrounding environment and community. The

Contractor will immediately report all injuries, illnesses, and accidents to the Base

representative and will provide follow-up documentation as requested.

The Contractor will provide its employees with all necessary personal protective equipment

(PPE) and supplies as warranted by the actions of its employees. At a minimum, Contractor

personnel will wear the following PPE, regardless of existing site conditions/hazards:

• Hard hat.

• Safety-toe boots.

• Safety glasses.

• Reflective traffic safety vest.

• Tank tops, shorts, or sleeveless shirts will not be permitted on-site at any time.

Electromagnetic Survey and Soil Analrsis

Gateway Lake Area, Ellsll'orth AFB, South Dakota

1.0 INTRODUCTION AND PURPOSE

This report presents the results of an electromagnetic (EM) survey and soil sampling analysis conducted

at a site located approximately 400 feet south of Gate\vay Lake and north of the wastewater treatment

facility at Ellsworth AFB, South Dakota. The survey is in response to two soil exploration borings

completed in August 2002 at a proposed building location, as shown in Figure I. Both soi I borings

encountered buried ash and glass debris, which suggested past disposal activities \\'ithin the proposed

building area. Based on the data from the borings, the areal extent of the buried debris was further

evaluated by conducting an EM survey. After field evaluation of the Elv[ data was completed,

three additional soil borings were conducted to confirm the survey results and characterize the buried

debris material. Evaluation of soil sampling data was also used to assess potential adverse impacts on

surrounding soi Is and ground water.

An inspection of historical aerial photographs from the Ellsworth Aerial Photograph Files provided

additional insight as to the extent of the buried debris and possibly the source. An aerial photograph from

August 1946 indicated a portion of the study area was once an open ravine that extended through the site

in an east-southeast direction. Some evidence of filling within the ravine was also indicated. Further to

the south a former incinerator could be seen, with roads extending from the incinerator to the ravine area,

suggesting the incinerator as a potential source ofthe debris.

Initially, the survey was to cover a 100-foot by 200-foot area that surrounded the locations of the

two exploration borings. However, the historical aerial photographs and field evaluation indicated a

potential for the buried debris to exist within a larger area. As a result, the extent of the EM survey was

expanded to cover an area 240-feet by 260-feet.

Current conditions at the site (EM survey area) consist of an open level grassy area that is bounded on the

north by a grotto of recently planted trees and on the east by a creek. To the west is the entrance road to

the wastewater treatment plant with the wastewater treatment plant facilities along the site's south

boundary. A general location map depicting the EM study area and existing site conditions are included

in Figure 1.

The EM survey covers an approximate 2-acre area, which included all of the area exhibiting a potential

(i.e., subtle surface expressions) to contain buried debris. The evaluation of EM data is based on

information acquired from the survey conducted on October 27,2002.

Electromagnetic Survey and Soil Analysis

Gateway Lake Area, Ellsworth AFB, South Dakota

2.0 ELECTROMAGNETIC SURVEY TECHNIQUE

The EM survey was conducted at the Gateway Lake site using a Geonics EM-31D Terrain conductivity

meter. Terrain conductivity is obtained by measuring the variances in electrical current, which is

electromagnetically induced into the earih by a transmitter coil in the quadrature phase, Current variation

is detected electromagnetically by a receiver coi L The center of each coi I is set apart at a known distance

and oriented in a vel1ical dipole mode, allowing for a continuous depth of investigation of approximately

18 feet. The EM technique measures composite electrical conductivity of subsurface soil, rock, and

ground water. The measured subsurface conductivity is a function of physical and chemical properties of

soil and/or rock, its porosity, moisture content in the pore spaces, and the conductivity of moisture (fluids)

that fill the pore spaces. EM conductivity values of the underlying soils are measured in millimhos/meter

(mmhos/m), or the equivalent millisiemens/meter (ms/m).

In addition to the measurement of conductivity in the quadrature phase, readings more sensitive to metal

detection were also obtained with the in-phase component of the instrument. EM values of the in-phase

component are measured as a proportion of the magnetic component of the electromagnetic signal in

parts per thousand (ppt). Both quadrature and in-phase readings were simultaneously recorded in the

field.

A homogeneous soil formation will have soil constituents that are some\vhat similar in physical chemical

composition. Pore openings; texture, particle size, and moisture content will be relatively constant

throughout the fonnation. If the soils have been altered, such as during excavation or fill placement, the

physical characteristics of the soils will also be altered and, in turn, affect the pore openings and moisture

content of the soil. If an area of land has been disturbed, i.e., fill with buried waste and/or debris, the

conductivity of the altered soils would likely differ from the surrounding in-situ, undisturbed soils.

Comparison of relative changes in conductivity or in-phase response can be used to map the extent of the

soil impacted by buried items and/or past excavation.

The occurrence of items associated with buried debris such as cinders and other waste materials will have

a notable effect on conductivity or in-phase values obtained from the EM survey. Conductivity values

will also vary significantly between clay and sandy soils, where clay soils tend to be more conductive

than sandy soils.

3.0 ELECTROMAGNETIC SURVEY PROCEDURES

The EM survey was designed to obtain conductivity information to a depth of approximately 18 feet over

the entire study area. The study area consists of an open grassy area with some trees and brush, with

surficial natural soils consisting primarily of clays.

Individual values of Ei'! data are not necessarily diagnostic in themselves, but comparative variations in

conductivity or in-phase data are significant. Therefore, measurements influenced by material such as

buried ash, metal, and glass debris or disturbed soils would exhibit anomalous EM values in comparison

to values associated with natural or non-impacted soils. Based on the available site information, the

EM survey grid was designed to identify soils impacted by the buried debris in contrast to soils exhibiting

background conditions.

The location of the grid was referenced to the west fence and entrance gate to the wastewater treatment

facility. EM data was acquired within the grid area along 27 north-5outh traverse lines spaced 10 feet

apart, with EM values recorded electronically at 5-foot increments along each line, resulting in a

5 x lO-foot grid for the entire EM survey area.

The orientation of each traverse line was maintained with stakes set at 40-foot increments around the

perimeter of the study area and at 50-foot (east-west) intervals within the interior portion of the study

area. The entire grid is a local horizontal datum, with the EM survey's base line (l00 West) referenced to

the entrance gate and Yvest fence for the wastewater treatment facility, as shown in Figure 1. Coordinates

and elevations for the subsequent soil borings within the EM survey area were surveyed into the vertical

and horizontal control grid for Ellsworth AFB.

4.0 EM SURVEY ANALYSIS AND RESULTS

4.1 QUADRATURE (CONDUCTIVITY) DATA

The location of the EM survey grid at the Site and the conductivity values obtained at each grid station

are provided in Figure 2. Contoured conductivity results are provided in Figure 3, with a corresponding

three-dimensional surface plot of the conductivity data provided in Figure 4.

The contoured data indicates a good correlation between areas with lower and consistent conductivity

values (background soils) in contrast to areas of high/low anomalous conductivity data associated with

impacted soil conditions. Background soil conditions are defined by relatively consistent conductivity

values (broad contours) in the perimeter areas of the study area. The tightened and anomalous

configuration of the contours, within the central portion of the study area, is suspected to contain

concentrations of buried ash and debris. The anomalous effects of cultural features are also evident.

Effects ofCultural Features

Positive conductivity values in the study area ranged from 28 to 456 mmhos/m. The broad range is

attributed primarily to the effects of metal fencing and buried utilities. Rapidly decreasing and/or

negative values often occur when metallic items such as metal fencing are encountered. Metal items can

cause a sudden decrease or reversal of induced current as the EM instrument passes near or over the item,

resulting in rapidly decreasing response at some data point locations.

Anomalous trends associated with the metal fencing and buried utilities were confirmed with field

observations and identification of known buried utilities. Such anomalies are accountable and do not

represent a response to buried debris. Significant anomalous effects, shown in Figures 3 and 4, exist

along the metal fence line that angle through the study area. Anomalous data along the fence is attributed

to its metal construction and the orientation of the instrument as it approached the fencing. A water line

was recently installed adjacent and north of the fence line, however, its impact is minimal in contrast to

the effect ofthe metal fencing. The most significant response occurred along the portion of the fence that

extends across the site in a southeasterly direction. For purposes of clarity in Figure 3, conductivity

values exceeding 140 mmhos/m have been omitted from the contoured results.

Other anomalous areas that are not attributed to subsurface conditions are located in the southern portion

ofthe study in the vicinity of the 100 North grid line. A linear west-east anomaly is indicated, which is in

response to a known buried electric line.

Subsurface Conditions

Conductivity of background or natural soils, as shown in Figure 2, typically ranged from approximately

75 to 90 mmhos/m and is predominant in the perimeter portions of the study area. A transition from

natural to impacted soil conditions appears to be within the range of 90 to 95 mmhos/m. A secondary

type of transition is suspected in the south-central portion of the study area, between the 140 East and

240 East grid lines. In this area, conductivity values exceed 95 mmhos/m, however, the broadly spaced

contours suggest the soils are not significantly impacted by buried debris and are suspected to contain

small amounts of debris that have been incorporated into cleaner soils.

Impacted soils are in areas where conductivity values exceed 95 mmhos/m and where tightly configured,

are inferred to be in response to the targeted buried debris. The brown line in Figure 3 shows the extent

of buried debris identified within the study area. The largest area appears to have the greatest

concentration of debris. Tightly configured contours depicting both high and low anomalies occur within

this area. The higher readings (> 95 mmhos/m) are associated with concentrations of buried debris that is

suspected to be primarily cinders and glass. Small, low anomalies along the 150 North grid line suggests

small metal items are incorporated within the debris mass. The t\\O larger low anomal ies (hachured

areas), at coordinates 180 North/240 East and at 130 North /270 East appear to be in response to larger

buried metal items.

In the northeast portion of the site, two separate areas of buried debris are also outlined. Both locations

based on field observations and the subtle anomalous responses. are inferred to contain small amounts of

debris located at or very near to the surface. At coordinates 240 North/2-W East a small pile of cinders

and glass were observed on the surface.

Additional information from the historical aerial photographs (Section 1.0) indicates a former

creek channel, as indicated by the dashed lines in both Figures 1 and 3, extended through the study area.

The study area is now level and is suspected to contain fill material that was disposed of within the

channel at the location corresponding to the anomalous conductivity data. Field observations of trace

amounts of cinders and glass at the site suggests the fill may be associated with debris originating from an

incinerator, which is reported to have been located south of the present day waste-water treatment facility.

In summary, anomalous conductivity data has identified three separate areas that are inferred to contain

buried debris, as shown in Figures 3 and 4. Two of the three areas are comparatively small and are

considered outliers of debris situated at or near the surface. The larger and main body of buried debris

covers an area of approximately 13,600 square feet (O.3-acre). Evidence of buried metal items is also

indicated in the central and southeastern portions of the main debris area, in the vicinity of coordinates

180 North1240 East and 130 North/270 East, respectively.

4.2 IN-PHASE DATA

Additional in-phase data were acquired with the EM31 simultaneously with the conductivity (quadrature)

data. As discussed in Section 2.0, the in-phase component is substantially more sensitive to metal objects

than the quadrature phase. Units of the in-phase component are parts per thousand (ppt).

The location of the EM survey grid and corresponding in-phase values obtained at each grid station are

provided in Figure 5. Contoured in-phase data is shown in Figure 6, with a corresponding surface plot

provided in Figure 7.

Due to greater sensitivity, the contoured in-phase data indicate a more significant response to the site's

metal fencing in comparison to anomalous conductivity data. In-phase values exceed 4.5 ppt in a broad

area that masks subsurface information at a distance of approximately IS to 20 feet either side of the

metal fencing. The buried electric line and the building located at the south boundary, between

coordinates 200 East and 260 East, also results in anomalous data ranging from 3 to 6.5 ppt. The masking

effect, however, is less extensive and is south ofthe buried debris area identified by conductivity data.

In the vicinity of the fencing, evidence of metal material within the debris cannot be determined.

However, contoured in-phase data, not influenced by the fencing or utilities, does p"ovide subsurface

information in the remaining portions of the study area. In the perimeter of the study area (beyond effect

of fencing) in-phase values are :S 2 ppt. The lower and/or zero values encountered in these areas reaffirm

the location of natural or non-impacted soils identified by conductivity data.

Anomalous in-phase data in the vicinity of coordinates 140 North/21 0 East and 130 North/260 East, as

shown in Figure 6, correlates with the same areas where low anomalous conductivity was encountered.

At both locations the contoured data depict a distinctive but a relatively broad configuration. The lack of

a rapidly changing or increasing in-phase data suggests the anomalies are in response to a cluster of

smaller metallic items rather than specific large metal objects, Based on the configuration and extent of

the anomalous data, the greatest concentration of metal material or items is located in the southeastern

portion of the buried debris area near coordinate 130 North/260 East.

5.0 SOIL BORINGS AND SOIL SAMPLING RESULTS

5.1 SOIL BORINGS

Three soil borings (SB02GWOIA, SB02GWOIB, and SB02GW02) \\ere completed at the Site as a

follow-up to the results of the EM survey. Original1y, t\'vo soil borings \\ere planned; however, due to an

obstruction, one boring (SB02GWOIA) was moved to an alternate location as SB02GWlB, The purpose

of the borings is to characterize the buried debris and to pro\ide background information in the area

outside of the identified limits of buried debris. The borings were completed on October 28,2002, at the

locations shown in Figure 3, Also included in Figure 3 are the locations of the two soil exploration

borings that were completed in August 2002,

One drilling rig, consisting of aCME 750, was used for drilling with 41/~-inch 1.0. x 7%-inch 0,0. x

hollow-stem-auger (HSA) to the required depths, Each soil boring \\as completed with continuous

core-barrel sampling at 5-foot intervals until competent shale bedrock was encountered, as determined by

the on-site geologist. Al1 soil samples were collected in accordance with ASTivl01586-84 and visually

classified by the on-site Earth Tech geologist using the USCS classification system ASTM 02487-85.

The driller also maintained a boring log to ensure the correlation of sample descriptions and depth

intervals. Copies ofthe boring logs are in Appendix A, A summary of the soil boring data is provided in

Table 1,

Soil boring data from SB02GW02 (outside of buried debris area) indicate natural soils within the study

area are predominantly olive-gray to gray silty clays that extend from the surface to the underlying shale

bedrock. Small seams of sand or gravel are also encountered within the clays. The underlying shale

bedrock is typically weathered in the upper 1 to 2 feet of the bedrock surface before changing to

competent shale. Bedrock elevations and estimated water level elevations (Table I) show a consistent

southeasterly slope through the study area.

Information from soil boring SB02GWO 1B indicates impacted soils consist of gravelly clay fil1 with

black ash and debris from the surface to a depth of approximately 6 feet. Information from the

August 2002 soil exploration borings (Appendix A) also indicates a similar description of soils to a depth

of 7.5 feet. Based on available soil boring data, the large area of buried debris, as shown in Figure 3, is

comprised of approximately 6 to 7.5 feet of black ash and clay with varying amounts of small metal and

glass. Traces of concrete and brick are also indicated in the August 2002 borings. At SB02GWO 1A, a

concrete obstruction was encountered at approximately 4 feet. Additional attempts at drilling and

sampling provided evidence ofsignificant amounts of concrete debris containing metal reinforcement bar.

The metal reinforcement bar is the likely cause of the large anomalous EM response shown in Figure 3.

As noted, the boring was moved to the SB02GWOIB location in order to obtain samples ofthe buried ash

and debris.

5.2 SOIL SAMPLING PROCEDURES

Soil samples were obtained from the buried ash and debris at boring SB02GWOlB for the purpose of

determining if the debris material presented an environmental concern. Since the source of the ash and

debris is uncertain a series of analyses were used for identifying various potential types of contamination

and hazardous material associated with the ash. Analyzed parameters included volatile organic

compounds (VOCs), semi-volatile compounds (SVOCs), select metals, metals (TCLP extract), chloride,

and dioxins/furans.

Samples from each boring, using the continuous core barrel, were screened with an organic vapor detector

in order to identify the most impacted depth interval(s). Hmvever, as noted by the non-detect results in

the boring logs, the screening of the soils was inconclusive. Therefore, representative samples, as

determined by the on-site geologist, were collected from both the buried ash debris and the underlying

soils. At SB02GWOIB a composite sample of the ash material was obtained from 3 to 6 feet and

analyzed for all of the above-mentioned parameters. A second composite soil sample (under the buried

ash and debris) was obtained from IOta 12 feet. E\:cept for the metals (TCl? extract), the sample was

also analyzed for the same parameters as the sample from 3 to 6 feet.

For comparative purposes, samples of background soils were obtained from boring SB02GW02. A

composite sample of the clays from 1 to 18 feet was collected and analyzed for the same select metals and

chloride as at SB02GWO IB. VOC, SVOC, and metals (TCL? extract) analysis were not conducted on

the background soi Isample.

All soil samples were collected, packed (with Chain-of-Custody record), and shipped to Severn Trent

Laboratories (STL) on October 28,2002.

5.3 ANALYTICAL RESULTS

Results for all analyzed parameters were provided electronically to Earth Tech. Due to the voluminous

amount of data a summary of the results for each of the analyzed categories is provided in Appendix B.

A summary of detected analytical results for VOCs, SVOCs, indicator parameters, metals, metals

(TCL? extract), and corresponding standards is provided in Table 2. A summary of dioxin/furan results

is provided in Table 3.

Detected results were compared to the US EPA Region 3 Risk Based Concentrations (RECs) dated

October 2002. RBC standards include the "industrial" and "DAF20" categories. The industrial soil

screening value at a I x IOE-6 risk level was used for dermal and inhalation risk and the dilution

attenuation factor (DAF) of 20 was used for evaluating the soil to ground water migration pathway.

Detected metal concentrations were compared to regional concentration ranges, as established in the

Remedial Investigation Report (1993) for nearby operational unit OU-6.

VOC and SVOC Results

The sample of the buried ash and debris (SB02GWO IB, 3-6 feet) resulted in the detection of three VOC

parameters and 12 SVOC parameters. Detected VOCs were at low concentrations, with none of the

detected parameters exceeding industrial or DAF 20 standards. Of the 12 SVOC detections,

five parameters (I ,4-dichlorobenzene, 2,4-dinitrotolune, 4-nitrophenol, N-nitrosodi-N-propylamine, and

I,2,4-trichlorobenzene) exceeded DAF 20 standards; one of the detected parameters

(N-nitrosodi-N-propylamine) exceeded industrial soil standards. The predominance of SVOCs within the

ash and debris is indicative of by-products associated with bum activities.

Analysis of the soil sample beneath the ash and debris (10-12 feet) detected four VOC parameters and

one SVOC parameter, each at low concentrations that did not exceed either the industrial or

DAF 20 standard. Based on the significant decrease of VOC and SVOC detections, the organic

contaminants found in the buried ash and debris does not appear to have greatly impacted the underlying

soils.

Chloride and Jl1etals Analysis

Chloride and mctals were also analyzed for the two samples from boring SB02GWO 1B. For comparison,

the same analyses were conducted for background soils (outside of buried debris) from boring

SB02GW02. i\S shown in Table 2, concentrations of chloride and metals \\ithin the ash and debris are

generally at higher concentrations than the corresponding parameters for soils beneath the debris and at

the background location. Although generally higher metal concentrations e\:ist in the debris, only arsenic

at 17 mg/kg, exceeded the Region 3 RBCs. The arsenic concentration \\as \\ithin the backgroLind

concentrations established for nearby OU-6.

[n contrast, concentrations of aluminum, calcium, and magnesium are lmver in the ash and debris than in

the underlying or natural soils. Since these three parameters are typically fOLind at high concentrations

\vithin natural soils, it is suspected that the ash and debris contains a lesser volume of natural soil within

the debris mass.

The underlying and background soil samples also have arsenic at concentrations that c\:ceed standards. In

addition, manganese also exceeds standards. Arsenic exceeds both industrial and OAF 20 standards.

whereas manganese exceeds only OAF 20 standards. As noted in the adjacent background soil column,

both arsenic and manganese fall within background ranges, indicating the concentrations are likely

associated with natural soil conditions.

[n general, detected metal concentrations ofsoils underlying the ash and debris and from background soils

typically fall \vithin the background ranges. This trend provides evidence that contaminants associated

with the ash and debris has not significantly impacted surrounding soils.

Metals rTCLP Extract)

The eight RCRA metals were analyzed following the Toxicity Characteristic Leaching Procedure (TCLP)

to determine if the ash and debris material is hazardous. Results as shown in Table 2, indicate all of the

metals tested resulted in non-detection or very low concentrations. None of the concentrations exceeded

the TCLP standards, indicating the ash and debris material is non-hazardous.

Dioxi/l/Furan Analysis

A summary of detected dioxin/furan data is presented on Table 3. Results sho\\' that dioxinsffurans are

not a concern in the ash and debris material.

To allow comparison to the EPA Region 3 RBC for 2,3,7,8 TCDO, Toxicity Equivalence Factors (TEFs)

were used to convert the concentrations of other dioxin/furan congeners into 2,3,7,8-TCOO equivalents.

TEFs were derived by Van don Berg et al. (1998), and are included on Table 3. Each congener's

concentration is multiplied by the applicable TEF and the resulting values were summed to obtain the

overall value for comparison to the 2,3,7,8-TCOO criteria. For this review, "zero" \vas used ffi the

concentration for non-detected congeners.

6.0 SUMMARY AND CONCLUSIONS

6.1 ELECTROMAGNETIC SURVEY

An evaluation of the EM survey at the Gateway Lake Site has identified both backgl"Ound and anomalous

EI\1 data. Based on the conductivity data three soil condition categories \\ere identified \\ithin the

investigation area. These categories include:

• Background clay soil conditions with conductivity \'alues ranging from approxi mate Iy

75 to 90 tnl11hos/m.

• Transition soils at 90 to 95 mmhos/m (area between natural soils and buried debris).

• Soils inferred to contain buried debris with anomalous conducti\'ity values typically greater than

95 mmhos/m. The higher anomalous conductivity values at these locations also exhibit rapidly

decreasing or increasing conductivity ranging from a low of 31 mmhos/m to a high of

176 mmhos/m.

The anomalous EM data indicates the areal extent of the ash and debris is approximately YJ-acre. Field

observations and soil boring data indicates the ash and debris is at a thickness from 6 to 7.5 feet and is

typically encountered within I foot ofthe surface.

Anomalous conductivity data also occurred due to the effects of metal fencing and buried utilities. These

anomalies are accountable and therefore do not indicate subsurface soil conditions or the effects of buried

debris.

In-phase anomalies were found to correlate with the anomalous conductivity data. Anomalous data

within areas adjacent to metal fencing or buried utilities were identified and determined not to be

representative of subsurface or impacted soil conditions. Tv·/o areas of anomalous in-phase data were

identified within the buried debris area and are swpected to be in response to a clustering of metal

material or items within the debris. Soil boring data indicates the anomalous response may be from metal

re-enforcement bar found within pieces of concrete.

6.2 SOIL SAMPLING ANALYSIS

Samples from the buried ash and debris were analyzed for VOCs, SVOCs, chloride, metals, metals

(TCLP extract), dioxin/furan, and pH. The range of analyses provided the necessary information to

determine the level of environmental concern associated with the ash and debris rrnterial. Samples of the

soils under the buried debris were also obtained and except for the TCLP extract analysis, were analyzed

for the same analytical categories. For comparison, background metals analyses were conducted on soil

samples obtained outside ofthe buried ash and debris area at boring SB02GW02.

Concentrations of detected parameters were evaluated and compared to US EPA Region 3,

RBC standards, which included the "industrial" and "DAF20" categories. Results of the TCLP extract

analysis and pH were compared to US EPA standards for toxicity characteristics. Concentrations for

metals were compared to regional background ranges established for nearby operational unit OU-6, and

data obtained from the background soil boring SB02GW02.

Results of the evaluation indicate the following conclusions for the Gateway Lake Area site:

Ash and Debris

• The exceedence of DAF 20 standards for 12 SVOC compounds indicates the buried ash and

debris have contaminants at levels which may pose a potential risk for contaminant migration to

ground water,

• With one exceedence of the industrial RBC standard, the buried ash and debris may present

some risk to persons working in the vicinity of the site, The risk, however, is likely to be

minimal since the industrial standard is based on dai Iy exposure over a period of 25 years

• Results for metals (TCLP) and pH indicate the ash and debris material is non-hazardous,

• Results for dioxins/furans indicate the maximum detected concentration was 1,5 pg/g, which is

below the screening criteria and similar to background concentrations, Results indicate

dioxins/furans are not an environmental concern in the ash and debris material.

Underlying and Background Soils

• Soils underlying the ash and debris and surrounding soils have not been greatly impacted by the

contaminants found in the ash and debris.

• In underlying and background soils, two parameters (arsenic and manganese) exceeded

DAF 20 standards; arsenic also exceeded industrial standards, The higher concentrations suggest

a potential impact; however, comparison to background information indicates the detected

concentrations are naturally-occurring.

• Monitoring well installation and/or fate and transport modeling could provide additional

information for determining long-term site-specific impacts on the surrounding soils and ground

water.
