# 1. INTRODUCTION

Weston Solutions, Inc. (WESTON ® 

# ) was contracted by the U.S. Environmental Protection

Agency (EPA) Region 6 to perform a Remedial Investigation/Feasib ility Study (RI/FS) and

Ecological Screening Risk Asse ssment (SRA) at the State Ma rine Superfund Site (hereafter

referred to as “the SMS Site”). The SMS Site is located in Port Arthur, Jefferson County, Texas

on the former Port Arthur Municipal Landfill. The Comprehensive Environmental Response,

Compensation, and Liability Act (CERCLA) Identif ication Number assigned to the SMS Site is

TXD099801102.

WESTON finalized a site-s pecific RI/FS Task Work Plan (T WP) in July 2001 to summarize the

technical scope of work to be performed at the SMS Site (WEST ON, 2001). The approach to the

ecological risk assessment is sp ecifically described in Appendix A and Task 6 of this July 2001

TWP. All work performed as part of the Stat e Marine RI, including this appendix, is being

completed under Contract Number DACA-45- 98-D-0004 through the U.S. Army Corps of

Engineers (USACE) Rapid Response Contract.

The primary objectives of the ecological risk assessment is to provid e EPA Region 6 with a

screening that will assist in interpreting current and future im pacts to the ecology associated with

the SMS Site. The technical approach to completing the SRA was based in part on the

methodology developed by WESTON and EPA Region 6 staff in th e Risk Assessment Work

Plan, Appendix A of the RI/FS TWP dated July 2001 and refined in subsequent meetings and

discussions with EPA, USACE, the National O ceanic and Atmospheric Administration (NOAA),

and WESTON staff.

The Ecological SRA consists of a screening leve l assessment organized into the following six

primary sections:

 Section 1—Introduction,

 Section 2—Characterization of Habitat,

 Section 3—Development of Exposure Concentrations,

 Section 4—Development of Screening Benchmark Values,

 Section 5—Characterization of Risk Screening, and

 Section 6—References.

# 2. CHARACTERIZATION OF HABITAT

The characterization of habitat is intended to describe the ecology and presence of ecological

receptors, including identification of sensitive habitat and species of special concern on or

adjacent to the SMS Site as well as those in the surrounding environs. The purpose of this

discussion is to establish whether there is just ification in believing th at ecological receptors

(including species of special status) are present or li kely to be present on or adjacent to the site or

in the surrounding environs.

2.1 REGIONAL ECOLOGY

The SMS Site is located on Pleasure Islet, a pe ninsula situated in Sa bine Lake in Jefferson

County, on the Texas-Louisiana boarder. See Figur e 2-1 for the Site Location Map. “Jefferson

County is located on the extreme seaward margin of the West Gulf Coastal Plain physiographic

province and entirely within the Grassland Coas tal Region of Texas,” (EPA, 2000b). Sabine

Lake, approximately 70 square miles (mi), is actually a bay system that leads to the Gulf of

Mexico via the 5-mi-long tidal outlet, Sabine Pass. Sabine Lake is considered an estuary due to

the fresh water from the Neches River and Sabine River mixing with tidal influx from the Gulf

of Mexico. This brackish water supports a wide variety of fish, crustace an, and marine mammal

species because the estuarine ecosystem provide s a shallow nutrient enriched environment.

Additionally, the barr ier islands that surround Sabine Lake pa rtially isolate the bay from the Gulf

waters and keep the nutrient-laden waters from being quickly washed out to sea (EPA, 2000b).

The SMS Site is located in a humid and warm climate with a growing season of 245 days per

year. The annual precipitation is 52 to 56 inches (in.) per year with the months December

through May experiencing the mo st precipitation (WESTON, 2001a ). The average maximum

temperatures range from approximately 60 o 

# F in January to approximately 92 o 

# F in July (United

States Climate Data, 1997). The average mini mum temperatures range from approximately 42 o 

# F

in January to approximately 74 o 

# F in July (United States Climate Data, 1997). This mild climate

and long growing season supports a variety of vegetation.

# 2-2 The SMS Site is located in the grassy coastal area of southeast Texas. There are extensive

wetlands present within 15 mi of the SMS Site . Based on a National Wetlands Inventory (NWI)

map, the SMS Site includes 13 frontage mi of es tuarine intertidal emergent wetlands (EPA,

2000b). The upland area at SMS S ite includes a few wooded areas, but primarily scrubs, shrubs,

and grasses cover the landscape. These grasslands support a variety of reptiles, birds, and

mammals.

The Sabine National Wildlife Refuge is the largest coastal marsh refuge on the Gulf of Mexico

and is located approximately 13 mi east of the SMS Site (EPA , 2000b). It is approximately 157,

951 acres (Parks of Southeast Te xas, 2002) and provides a large ar ea of coastal wetlands to many

wintering and migratory waterfowl. It is also a major nursery area for many estuarine-dependent

marine species such as alligators, reptiles , mammals, and numerous wading and marsh birds

(EPA, 2000b).

2.1.1 Terrestrial Habitat

An abundance of terrestrial animal s inhabit the wetlands and grassl ands near the SMS Site. The

Nine-banded armadillo ( Dasypus novemcinctus ) lives regionally depend ing on soil texture, as

armadillos rely on soft soil in order to probe for insects and other forms of animal life in the

ground. The common gray fox ( Urocyon cinereoargenteus ) is known to ex ist throughout the

state of Texas, but primarily inhabi ts the eastern region. The ringtail ( Bassariscus astutus ), a

fox-like animal with the face of a raccoon, lives in the region of the SMS Site. Frequenting the

brackish marshes are bobcat ( Lynx rufus ), mink ( Mustela vison ), and swamp rabbit ( Sylvilagus

aquaticus ) (Davis and Schmidly, 1994).

The coastal region has many fish eating and migrat ory birds such as the American white pelican

( Pelecanus erythrorhynchos ), the wood stork ( Mycteria americana ), the white ibis ( Eudocimus

albus ), and the sandhill crane ( Grus canadensis ). Shorebirds include gulls and terns ( Laridae ),

upland plover ( Bartramia longicauda ), sandpiper ( Scolopacidae ), common snipe ( Gallinago

gallinago ), and short-bi lled dowitcher ( Limnodromus griseus ) (Texas State Historical

Association, 2001).

# 2-3 Two bird rookeries have been identified with in 15 mi of SMS Site including Sydnes Island and

Dooms Island. The Dooms Island rookery is located approximately 1⁄4 mile northeast of the site

and is a nesting colony for the black skimmer ( Rynchops niger ) (EPA, 2000b). Approximately

1.75 mi northeast of the site is Sydn es Island rookery. It is also a nesting colony for the black

skimmer ( Rynchops niger ) (EPA, 2000b). Both rookeries are managed by the Texas Parks and

Wildlife Department (TPWD) [EPA, 2000b].

2.1.2 Aquatic Habitat

Commercial and recreational fishing occurs ye ar round at Sabine Lake. The total average

commercial production is approximately 660,000 pounds per year (EPA, 2000b). Fish species

inhabiting Sabine Lake in clude southern flounder ( Paralichthys lethostigma ), black drum

( Pogonias cromis ), red drum ( Sciaenops ocellatus ), spotted seatrout ( Cynoscion nebulosus ),

northern red snapper ( Lutjanus campechanus ), and the greater amberjack ( Seriola dumerilli )

(Texas and Louisiana Saltwater Fishing Guides, 2002). The estuarine envi ronment also supports

a variety of crustaceans including brown shrimp ( Penaeus aztecus ), white shrimp ( Penaeus

setiferus ), pink shrimp ( Penaeus duorarum ), and American commercial oyster ( Crassostrea

virginica ) [TPWD, 2002]. Some marine mammals migrate or reside in Sabine Lake including

the Atlantic bo ttlenose dolphin ( Tursiops truncatus ) and the manatee ( Trichechus manatus )

[EPA, 2000b]. River otters ( Lutra canadensis ) also inhabit the marshy ar eas of the Gulf region

in Texas (Davis and Schmidly, 1994).

The marshy estuarine regions in Lake Sabine support a variety of amphibians and reptiles

including the state and federall y threatened green turtle ( Chelondia mydas ); the state and

federally threatened loggerhead sea turtle ( Caretta caretta ); and the state and federally

endangered Ridley sea turtle ( Lepidochelys kempii ) (TPWD, 2001). Other amphibians and

reptiles that inhabit the region include the alligator snapping turtle ( Macroclemys temminckii ),

southern dusky salamander ( Desmognathus auriculatus ), eastern newt ( Notphthalmus

viridescens ), bronze frog ( Rana clamitans clamitans ), mud snake ( Farancia abacura ), and the

Gulf crayfish snake ( Regina rigida sinicola ) (Texas Memorial Museum, 2002).

# 2-4 2.1.3 Threatened, Endangered, and Species of Special Concern

Within a 4-mile radius and 15-mile downstream distance from the SMS Site, federally listed

endangered species identified include the Gulf saltmarsh snake ( Nerodia clarkii ), Black rail

( Laterallus jamaicensis ), and Texas diamondback terrapin ( Malaclemys terrapin ) [EPA, 2000b].

Additionally, the Bald eagle ( Haliaeetus leucocephalus ) was identified as a federally listed

threatened species. The above species benefit from the salt, brackish, and fresh water marshes

and estuaries around the SMS Site. Th e American swallo w-tailed kite ( Elanoides forficatus ) is a

State-listed threatened species that was identified near the SMS Site (EPA, 2000b). The

swallow-tailed kite may inha bit the rivers, lakes, and ponds adjacent to Lake Sabine.

The WESTON RI/FS TWP for the SMS Site outlined nineteen additional federally endangered

species that exist within Jefferson County. Thes e species are listed in Attachment C (TPWD,

1995; USFWS, 1994, 1995; CLI, 1995).

2.2 SITE ECOLOGY

The SMS Site encompasses approximately 34 acres on Pleasure Islet. It is bounded to the north

by the Palmer Barge Line site, to the west by Old Yacht Club Road, to the south by undeveloped

property, and to the east by Sa bine Lake (WESTON, 2001a).

The Islet on which the SMS Site is located is a manmade landmass, consisting of dredge spoils

generated during the construction and maintenance of the Sabine-N eches Canal. The canal was

constructed between 1898 and approximately 1920. The islet that was form ed was isolated from

the mainland until a land bridge was constructed in the mid to late 1950s. The original landscape

was heavily vegetated with shrub/scrub type ve getation. Similar vegetation exists on the islet

today in areas that remain undeveloped. The upla nd portion of the SMS Site is representative of

undisturbed habitat and includes larger grassy areas with so me shrubs and small trees.

Significant portions of the site have been cleared and graveled or are developed with buildings,

tanks, and other facilities (WESTO N, 2001a). Figure 2-2 illustrate s the habitat of the SMS Site.

Ground elevations range from sea level along the s horelines to a maximum of 11 feet (ft) above

sea level in the north-central portions of the site. The highest relief on the Islet is associated with

# Weston Solutions, Inc. – Final Ecological Screening Risk Assessment

H:\STATE MARINE\RI REPORT (FINAL)\APPENDIX D (E COLOGICAL RISK ASSESSMENT)\TEXT\ECORA.DOC 5/8/03



# 2-5 the City of Port Arthur’s former municipal la ndfill, which underlies most of the central and

northern portions of the site. On -site elevations range from approximately 2 to 7 ft above sea

level. Drainage on the Islet is toward the adjacent waterways with surface drainage on the SMS

Site occurring to the ea st-southeast in the direction of Sabine Lake.

The soils on the islet are shallow (0 to 4 ft) and reflect the nature of th e sediments dredged from

Sabine Lake, primarily sandy silts an d clays. The central portion of the islet, including the entire

SMS Site, is underlain by a municipal landfill that is covered by up to 2 ft of fill. In addition, the

southwest portion of the Palmer site and the northwest portion of the State Marine property is the

historical location of the landfill burn pit. Shal low groundwater occurs close to the land surface

and may be brackish, which would limit the devel opment of larger trees or deep-rooted plant

communities (WESTON, 2001a).

The SMS Site shoreline has been heavily modifi ed by construction of a bulkhead that forms the

outer edge of a pier that ru ns along most of the property boundary. A small portion of the

southeastern shoreline retains some natural fe atures. The SMS Site shoreline varies; some

natural shoreline exists in the northern and so uthern portions of the property. The nearshore

central area is heavily modified by the presence of piers, slips, ma rine salvage debris, and several

sunken barges (WESTON, 2001a).

2.2.1 Terrestrial Habitat

The on-site investigation area was the upland terrest rial area. The site visit to the SMS Site

showed vegetation to be thriving, except in areas impacted by contamination. Plant samples

collected during the visit were identified as fo llows, the overstory at the site consists of

sugarberry ( Celtis laevigata ), Chinese tallow ( Sapium sebiferum ), and honey mesquite ( Prosopis

glandulosa ). The herbaceous la yer includes panicum ( Panicum dichotomiflorum ), olneyi-pod

morning glory ( Ipomoea trichocarpa ), seaside golden rod ( Solidago sempervirens ), iva ( Iva

annua ), ragweed ( Ambrosia trifida ), and muskmelon ( Cucumis melo ). Miscellaneous vegetation

includes blackberry ( Rubus ), rattlebox ( Sesbania drummondii ), Brazilian verbena ( Verbena

brasiliensis ), and Texas lantana ( Lantana horrida ).

# 2-6 The grassy upland areas of the SMS Site suppor t a variety of ecological receptors. Mammals

that inhabit the on-site area incl ude the eastern gray squirrel ( Sciurus carolinensis ), eastern fox

squirrel ( Sciurus niger ), eastern woodrat ( Neotoma floridana ), cotton mouse ( Peromyscus

gossypinus ), common raccoon ( Procyon lotor ), red fox ( Vulpes vulpes ), Virginia opossum

( Didelphis virginiana ), coyote ( Canis latrans ), woodland vole ( Microtus pinetorum ), armadillo

( Dasypodidae ), and axis deer ( Cervus axix ) (Davis and Schmidly, 1994).

The SMS Site has a wide variet y of migratory birds and waterf owl. The following birds were

observed during the site visit: the red-winged black bird (Agelaius phoeniceus), snowy egret

( Egretta thula ), mourning dove ( Zenaida macroura ), great blue heron ( Ardea herodias ), purple

swallow ( Progne subis ), Brewer’s black bird ( Euphagus cyanocephalus ), boat-tailed grackle

( Quiscalus major ), marsh hawk ( Circus cyaneus ), western king bird ( Tyrannus verticalis ),

northern mocking bird ( Mimus polyglottos ), belted king fisher ( Ceryle alcyon ), and lesser night

hawk ( Chordeiles acutipennis ). See Attachments A and B fo r more details on site-specific

observations.

2.2.2 Aquatic Habitat

The off-site investigation area was divided into three subareas: intertidal, nearshore, and

offshore. The intertidal area represents expo sed sediments from the top of the bank along the

shoreline to approximately the mean lower low water mark. The nearshore area is irregular in

shape and encompasses both shallow sediments a nd those close to poten tial upland or on-site

sources. The offshore area is a rectangular area of about 150 to 200 ft wide paralleling the

navigation channel and representing the area most heavily influenced by ship traffic

(WESTON, 2001a).

The intertidal zone at the SMS Site supports a variety of macroinvertebrates that thrive on the

sandy shores of the brackish water of Lake Sa bine. These animals include American oyster

2.2.3 Threatened and Endangered Species

An endangered species is a native species whose prospects for surviv al or recruitment within the

State of Texas or the United States are in immine nt jeopardy. This determination is based on the

species status in Texas for state listed species and the rest of the United States for federally listed

species. A threatened species is a native sp ecies that, although not pr esently in danger of

extirpation, is likely to become endangered in th e foreseeable future in the absence of special

protection and management efforts. A special concern species may be one of the following

(USFWS, 1994):

 Category I—a native species wi th a presently stable or increasing population that

current evidence indicates is especially vu lnerable to extirpation because of limited

range, low population, or other factors.

 Category II—a native species identified by technical experts as possibly threatened or

vulnerable to extirpation but for which little, if any, evidence exists to document the

population level, range or other fa ctors pertinent to its status.

Jefferson County, Texas, currently has 48 animal species that are listed as endangered or

threatened under either federal or state guidelines. Attachment C presents a detailed list of

threatened and endangered species that are found in Jefferson County, Texas.

A review by both the U.S. Fish and Wildlife Service (USFWS) and the Texas State Parks and

Wildlife Department (TPWD) suggests that no federa lly or state listed or proposed threatened or

endangered species are likely to occur at the SMS Site because of the general lack of appropriate

habitat (WESTON, 2001b).

# 3. DEVELOPMENT OF EXPOSURE CONCENTRATIONS

The estimation of environmental exposure i nvolves the quantificat ion of constituent

concentrations at points of likely exposure. C onstituent concentrations at these points (called

exposure point concentrati ons) are critical in determining th e amount of exposure and subsequent

risk to ecological receptors. The development of exposure concentrations for this SRA is based

on estimating an average or maximum concentration for constituents that were detected in soil,

sediment, or groundwater. If a constituent was not detected in any sample from a particular

media, it was excluded altogether from that medium.

All current, future, and incomplete exposure path ways expected to occur at the SMS Site are

identified in the Ecological Site Conceptual M odel (Figure 3-1). Exposure is based on general

assumptions for contaminant migration and transport from wastes to various media on and

adjacent to the site (i.e., soil, sediment, groundw ater, and surface water). Exposure and receptor

information for the conceptual site m odel can also be summarized below:

Exposure Medium Exposure Routes

Receptor

Group Soils Sediment Surface

Water Aquatic

Prey Terrestrial

Prey Groundwater Direct

Contact Ingestion Inhalation

Aquatic X X X X -- F X X N

Terrestrial X X X -- X -- X X N

Notes:

X = Current exposure.

N = Not evaluated.

F = Future exposure.

-- = Incomplete exposure.



# Discussion of the development of exposure concen trations for soil, sediment, and groundwater is

# 3-2 3.1 SOIL

In the ecological SRA, exposure point concentr ations for upland soils were developed from

known or suspected source areas (“hot spots”) as follows:

 Former Wastewater Impoundments

 Wastewater Treatment Facility

 Current Aboveground Storage Tanks

 Maintenance Shed Area

 Tar Burn Area

 Former Lauren Tank Farm

Exposure concentrations were also developed for constituents in soil by grouping randomly

sampled data from “nonsource” areas together and by grouping all surface or all subsurface

sampling data together (as “site -wide” exposure). Surface soils were sampled from the surface

down to approximately 6 in. in depth. Subsurface soils were sampled anywhere from 3 to 40 ft

below the surface. The exact depth intervals for so il samples that were taken from 3 ft or below

are presented in Section 6 of th e RI Report. The spatial combin ation of hot spot and nonsource

area and site-wide data was developed based on th e approach that ecological receptors may be

randomly exposed across the entire site or exposed within a specific location depending on

specific activity patterns of each receptor. Figure 3-2 shows the soil sampling locations.

Receptor exposure is representative of the averag e exposure expected to occur within a defined

area of contact or the maximum exposure expected to occur at a single location. The average

concentration was calculated as an average of a ll surface soil concentrations from all locations

within a defined area of exposure (e.g., Tar Burn Area) and is based on either the 95% upper

confidence limit (UCL) concentratio n of the mean or the straight arithmetic average in cases

where the 95% UCL was less than the arithmetic average or greater than maximum detected

concentration. The maximum concentration repres ents the highest detected soil concentration

from a single location. It is important to note that in a limited number of cases, some

constituents with a high number of nondetect da ta points showed aver age concentrations in

excess of the maximum detected co ncentration. A summary of soil analytical data for hot spots,

nonsource and site-wide areas, including average and maximum exposure concentrations, are

presented in Tables 3-1 through 3-9.

# 3-3 3.2 SEDIMENT

The sediment investigation was conducted in Lake Sabine adjacent to the SMS Site and is

referred to as the “off-site” investigation area. Figure 3-2 shows the off-site sampling locations.

The purpose of the investigation was to characteri ze the vertical and lateral extent of off-site

sediment contamination. Based on distance from th e shoreline, the off-site area was broken into

the following three areas:

 Intertidal Area,

 Nearshore Area, and

 Offshore Area.

All three areas posed the likelihood of exposure. The subsurface sediment in the Nearshore Area

was also screened during the ecological SRA.

Receptor exposure is representative of the averag e exposure expected to occur within a defined

area of contact or the maximum exposure expected to occur at a single location. The average

concentration was calculated as an average of all surface sediment concentrations from all

locations within a defined area (e.g., Intertidal Ar ea) and is based on either the 95% UCL

concentration of the mean or the straight arit hmetic average in cases where the 95% UCL was

less than the arithmetic average or greater than maximum detected concentration. The maximum

concentration was calculated as the highest detect ed soil concentration from a single location. It

is important to note that in a limited number of cas es, some constituents w ith a high degree of

nondetect data showed average conc entrations in excess of the maxi mum detected concentration.

Summaries of analytical data for the off-si te investigation areas, including average and

maximum exposure concentrations, are pr esented in Tables 3-11 through 3-15.

3.3 GROUNDWATER

Six monitoring wells were installed at three differe nt locations in the uplands area of the site to

characterize groundwater. Pairs of shallow and deep monitoring wells were installed at each of

the three locations as follows:

 SM061A – SM061B

 SM068A – SM068B

# 3-4  SM116A – SM116B

The letter “A” identifies the de ep well (< 40-45 ft) and the lette r “B” identifies the shallow well

(20-25 ft). Figure 3-2 shows th e location of these wells in relation to the upland soil sampling

locations. Due to the lack of a defined aquife r, groundwater was not grouped into specific units

of exposure. Instead all sampling data was evalua ted together in an effort to characterize the

overall condition of groundwater at the SMS Site. Therefore, exposure concentrations were

based on the maximum exposure expected to occur at a single well rather th an an average of well

data. The maximum concentration represents th e highest detected gro undwater concentration

from that well. A summary of analytical da ta for groundwater is presented in Table 3-17.

3.4 BACKGROUND

Background soil and sediment samples were collect ed at specific reference area locations as

shown on Figure 3-3. During the WESTON 2001 RI, three su rface soil samples (SM133,

SM134, and SM135) were collected from the northwe st area of the SMS S ite, and five surface

sediment samples (RFW01 through RFW05) were collected from the area adjacent to Sydnes

Island. The site-specific background values we re calculated using the arithmetic mean for

constituents with 100% frequency of detecti on or the maximum detected concentration for

constituents with less than 100% frequency of detection. The an alytical results for background

soil samples are presented in Table 3-10, and the background sediment results are presented in

Table 3-16.

Constituent was detected at a frequency of 100%; no detection limit data was reported.The Coefficient of Variation (CV) is calculated as follows: Arithmetic Mean / Std. Deviation; a C.V. < 1 indicates that dataset came from a normally distributed population.The Distribution Test (DT) is calculated using the Wilk Shiparo Test for datasets of 50 or less or the D'Agostino Test for datasets of greater than 50 (SiteSTAT 1.0).The 95% Upper Confidence Limit (UCL) is calculated as a one-sided upper limit calculation on either the mean or the logarithmic mean at a 95% probability level (SiteSTAT 1.0).The 95%UCL was based on the following methodology: if DT equals lognormal then the lognormal 95%UCL was used, if DT equals normal then normal 95%UCL was used, if DT equals unknown or normal/lognormal and CV is less than 1.0, then the normal 95%UCL was used.A normal DT indicates that the dataset came from a normally distributed population. Likewise, if the DT was lognormal then the dataset came from a lognormally distributed population.5/6/2003: 10:57 AMState Marine Soil Summary Tables - Ecological.xls: Tables 3-1 and 5-1CASRN ConstituentData Group UnitsArithmeticAverageStandardDeviation95%UCL(Normal)95%UCL(Lognormal) 95%UCLCoefficient ofVariation Distribution Type92-52-4 1,1'-BiphenylBNA mg/kg 2 5 40% 0.410 0.480 0.013 0.025 0.138 0.109 0.242 19.644 0.242 0.794 Normal/Lognormal91-57-6 2-MethylnaphthaleneBNA mg/kg 2 5 40% 0.410 0.480 0.033 0.220 0.181 0.084 0.260 1.279 0.260 0.464Unknown106-44-5 4-Methylphenol (p-Cresol) BNA mg/kg 1 5 20% 0.410 0.480 0.023 0.023 0.180 0.089 0.264 2.797 0.264 0.494Unknown83-32-9 AcenaphtheneBNA mg/kg 3 5 60% 0.410 0.410 0.014 0.085 0.105 0.095 0.196 8.636 0.196 0.907 Normal/Lognormal208-96-8 AcenaphthyleneBNA mg/kg 4 5 80% 0.410 0.410 0.042 0.350 0.174 0.129 0.297 1.867 0.297 0.743 Normal/Lognormal98-86-2 AcetophenoneBNA mg/kg2 5 40% 0.410 0.480 0.023 0.120 0.159 0.088 0.242 2.015 0.242 0.553Normal120-12-7 AnthraceneBNA mg/kg5 5 100%NANA 0.019 0.450 0.191 0.195 0.377 15.533 15.533 1.020Normal/Lognormal100-52-7 BenzaldehydeBNA mg/kg 2 5 40% 0.410 0.450 0.025 0.051 0.142 0.096 0.234 2.069 0.234 0.674 Normal/Lognormal56-55-3 Benzo(a)anthraceneBNA mg/kg5 5 100%NANA 0.100 0.830 0.272 0.314 0.572 1.885 1.885 1.156Lognormal50-32-8 Benzo(a)pyreneBNA mg/kg5 5 100%NANA 0.100 0.650 0.248 0.230 0.468 1.160 1.160 0.929Lognormal205-99-2 Benzo(b)fluorantheneBNA mg/kg 5 5 100% NA NA 0.130 1.100 0.420 0.401 0.802 2.980 0.802 0.954 Normal/Lognormal191-24-2 Benzo(g,h,i)peryleneBNA mg/kg4 5 80% 0.410 0.410 0.056 0.240 0.166 0.073 0.236 0.460 0.236 0.442Normal/Lognormal207-08-9 Benzo(k)fluorantheneBNA mg/kg5 5 100%NANA 0.061 0.340 0.149 0.113 0.256 0.497 0.256 0.761Normal/Lognormal86-74-8 CarbazoleBNA mg/kg3 5 60% 0.410 0.410 0.031 0.130 0.122 0.085 0.203 1.127 0.203 0.701Normal/Lognormal218-01-9 ChryseneBNA mg/kg5 5 100%NANA 0.098 1.300 0.434 0.493 0.904 4.650 4.650 1.138Lognormal53-70-3 Dibenz(a,h)anthraceneBNA mg/kg5 5 100%NANA 0.025 0.100 0.059 0.038 0.095 0.191 0.095 0.638Normal/Lognormal132-64-9 DibenzofuranBNA mg/kg2 5 40% 0.410 0.480 0.030 0.033 0.143 0.102 0.240 2.673 0.240 0.718Normal117-84-0 Di-n-octylphthalateBNA mg/kg1 5 20% 0.410 0.480 0.033 0.033 0.179 0.083 0.257 1.237 0.257 0.463Unknown206-44-0 FluorantheneBNA mg/kg5 5 100%NANA 0.065 2.200 0.575 0.913 1.446 46.075 46.075 1.588Lognormal86-73-7 FluoreneBNA mg/kg2 5 40% 0.410 0.480 0.057 0.097 0.161 0.079 0.236 0.479 0.236 0.492Normal/Lognormal193-39-5 Indeno(1,2,3-cd)pyrene BNA mg/kg5 5 100%NANA 0.085 0.420 0.177 0.139 0.309 0.520 0.520 0.783Lognormal91-20-3NaphthaleneBNA mg/kg2 5 40% 0.410 0.480 0.036 0.120 0.161 0.083 0.240 0.864 0.240 0.514Normal/Lognormal85-01-8 PhenanthreneBNA mg/kg5 5 100%NANA 0.031 1.100 0.294 0.454 0.727 26.933 26.933 1.546Lognormal129-00-0 PyreneBNA mg/kg5 5 100%NANA 0.130 1.600 0.490 0.627 1.088 6.594 6.594 1.280Lognormal7429-90-5 AluminumMETAL mg/kg5 5 100%NANA 2590.000 11100.000 6854.000 3050.743 9762.759 16297.167 9762.759 0.445Normal/Lognormal7440-36-0 AntimonyMETAL mg/kg5 5 100%NANA 1.100 5.700 2.680 1.923 4.513 10.061 4.513 0.717Normal/Lognormal7440-38-2 ArsenicMETAL mg/kg5 5 100%NANA 4.700 10.400 6.760 2.171 8.830 9.663 8.830 0.321Normal/Lognormal7440-39-3 BariumMETAL mg/kg5 5 100%NANA 91.700 292.000 163.920 86.911 246.786 356.168 246.786 0.530Normal/Lognormal7440-41-7 BerylliumMETAL mg/kg5 5 100%NANA 0.580 0.980 0.742 0.170 0.904 0.956 0.904 0.229Normal/Lognormal7440-43-9 CadmiumMETAL mg/kg3 5 60% 0.150 0.180 0.490 1.100 0.493 0.434 0.907 24.378 0.907 0.880Normal/Lognormal7440-70-2 CalciumMETAL mg/kg 5 5 100% NA NA 2920.000 10400.000 5848.000 2776.683 8495.455 11338.721 8495.455 0.475 Normal/Lognormal7440-47-3 ChromiumMETAL mg/kg5 5 100%NANA 11.300 25.600 16.820 6.672 23.182 28.069 23.182 0.397Normal/Lognormal7440-48-4 CobaltMETAL mg/kg5 5 100%NANA 4.400 9.800 6.780 2.265 8.940 10.313 8.940 0.334Normal/Lognormal7440-50-8 CopperMETAL mg/kg5 5 100%NANA 24.100 299.000 95.020 114.708 204.389 857.649 857.649 1.207Lognormal57-12-5 Cyanide, TotalMETAL mg/kg1 5 20% 0.120 0.130 0.210 0.210 0.091 0.067 0.154 0.216 0.154 0.731Unknown7439-89-6 IronMETAL mg/kg 5 5 100% NA NA 14700.000 48400.000 23740.000 13977.231 37066.723 47276.505 47276.505 0.589Lognormal7439-92-1 LeadMETAL mg/kg5 5 100%NANA 49.000 150.000 88.740 44.895 131.545 186.322 131.545 0.506Normal/Lognormal7439-95-4 MagnesiumMETAL mg/kg 5 5 100% NA NA 761.000 2850.000 1600.200 823.820 2385.679 3503.717 2385.679 0.515 Normal/Lognormal7439-96-5 ManganeseMETAL mg/kg5 5 100%NANA 205.000 528.000 335.400 125.826 455.370 544.893 455.370 0.375Normal/Lognormal7439-97-6 MercuryMETAL mg/kg4 5 80% 0.070 0.070 0.060 0.980 0.271 0.403 0.655 23.000 23.000 1.488LognormalFrequency of DetectionRange of DetectionLimitsRange of DetectedConcentrationsTable 3-2Surface Soil Analytical Results (Waste Water Treatment Facility)5/5/2003: 5:05 PMState Marine Soil Summary Tables -

Likewise, if the DT was lognormal then the dataset came from a lognormally distributed population.5/5/2003: 5:05 PMState Marine Soil Summary Tables - Ecological.xls: Tables 3-2 and 5-2CASRN ConstituentData Group UnitsArithmeticAverageStandardDeviation95%UCL(Normal)95%UCL(Lognormal) 95%UCLCoefficient ofVariation Distribution Type92-52-4 1,1'-BiphenylBNA mg/kg 1 7 14% 0.390 0.420 0.040 0.040 0.180 0.062 0.226 0.384 0.226 0.344Unknown91-57-6 2-Methylnaphthalene BNA mg/kg 3 7 43% 0.390 0.420 0.018 0.110 0.137 0.087 0.201 1.115 0.201 0.639Unknown106-44-5 4-Methylphenol (p-Cresol) BNA mg/kg 1 7 14% 0.390 0.420 0.046 0.046 0.181 0.060 0.225 0.349 0.225 0.330Unknown83-32-9 AcenaphtheneBNA mg/kg 3 7 43% 0.390 0.420 0.014 0.460 0.186 0.150 0.296 4.071 0.296 0.805Normal208-96-8 AcenaphthyleneBNA mg/kg 5 7 71% 0.390 0.410 0.022 0.180 0.097 0.091 0.163 0.697 0.163 0.941Unknown98-86-2 AcetophenoneBNA mg/kg4 7 57% 0.390 0.420 0.016 0.049 0.101 0.096 0.172 1.202 0.172 0.950Unknown120-12-7 AnthraceneBNA mg/kg4 7 57% 0.400 0.420 0.014 1.500 0.318 0.528 0.706 9.294 9.294 1.664 Lognormal100-52-7 BenzaldehydeBNA mg/kg 4 7 57% 0.390 0.410 0.008 0.032 0.094 0.099 0.167 3.575 3.575 1.050Unknown56-55-3 Benzo(a)anthraceneBNA mg/kg6 7 86% 0.410 0.410 0.034 3.000 0.507 1.101 1.315 11.294 11.294 2.174 Lognormal50-32-8 Benzo(a)pyreneBNA mg/kg7 7 100%NANA 0.017 2.700 0.448 0.994 1.178 13.474 13.474 2.217 Lognormal205-99-2 Benzo(b)fluoranthene BNA mg/kg 7 7 100% NA NA 0.030 4.400 0.722 1.623 1.914 22.291 22.291 2.247 Lognormal191-24-2 Benzo(g,h,i)peryleneBNA mg/kg 4 7 57% 0.400 0.420 0.059 0.970 0.262 0.319 0.496 0.955 0.955 1.218 Lognormal207-08-9 Benzo(k)fluoranthene BNA mg/kg 6 7 86% 0.410 0.410 0.019 1.800 0.321 0.655 0.802 9.929 9.929 2.045 Lognormal85-68-7 Butylbenzylphthalate BNA mg/kg 1 7 14% 0.390 0.550 0.030 0.030 0.189 0.075 0.245 0.545 0.245 0.398Unknown86-74-8 CarbazoleBNA mg/kg 3 7 43% 0.390 0.420 0.022 0.230 0.155 0.091 0.222 1.101 0.222 0.586Unknown218-01-9 ChryseneBNA mg/kg 7 7 100% NA NA 0.021 2.800 0.467 1.030 1.223 12.803 12.803 2.207 Lognormal53-70-3 Dibenz(a,h)anthracene BNA mg/kg 3 7 43% 0.390 0.420 0.031 0.330 0.172 0.106 0.250 0.826 0.250 0.617Normal132-64-9 DibenzofuranBNA mg/kg2 7 29% 0.390 0.420 0.009 0.180 0.173 0.073 0.226 1.903 0.226 0.422Unknown206-44-0 FluorantheneBNA mg/kg7 7 100%NANA 0.021 10.000 1.510 3.744 4.260 581.525 581.525 2.479 Lognormal86-73-7 FluoreneBNA mg/kg 1 7 14% 0.390 0.420 0.470 0.470 0.241 0.101 0.316 0.319 0.316 0.418Unknown193-39-5 Indeno(1,2,3-cd)pyrene BNA mg/kg7 7 100%NANA 0.015 1.100 0.197 0.399 0.490 2.605 2.605 2.024 Lognormal91-20-3NaphthaleneBNA mg/kg3 7 43% 0.390 0.420 0.017 0.078 0.132 0.090 0.198 1.113 0.198 0.682Unknown87-86-5 PentachlorophenolBNA mg/kg1 7 14% 0.980 1.100 0.280 0.280 0.481 0.092 0.549 0.589 0.549 0.192Unknown85-01-8 PhenanthreneBNA mg/kg6 7 86% 0.400 0.400 0.014 3.800 0.625 1.402 1.654 44.577 44.577 2.244 Lognormal129-00-0 PyreneBNA mg/kg7 7 100%NANA 0.024 8.400 1.290 3.136 3.593 222.314 222.314 2.430 Lognormal7429-90-5 AluminumMETAL mg/kg7 7 100%NANA 593.000 3490.000 1522.143 1227.808 2423.827 3724.832 3724.832 0.807 Lognormal7440-36-0 AntimonyMETAL mg/kg2 3 67% 0.770 0.770 2.100 2.500 1.662 1.124 3.556 41182.346 3.556 0.676Normal/Lognormal7440-38-2 ArsenicMETAL mg/kg7 7 100%NANA 1.500 7.900 3.171 2.512 5.016 7.073 5.016 0.792Unknown7440-39-3 BariumMETAL mg/kg7 7 100%NANA 49.600 296.000 208.800 87.647 273.167 452.259 273.167 0.420Normal7440-41-7 BerylliumMETAL mg/kg5 7 71% 0.070 0.070 0.080 0.310 0.120 0.100 0.194 0.362 0.194 0.836Normal/Lognormal7440-43-9 CadmiumMETAL mg/kg1 7 14% 0.140 0.150 0.480 0.480 0.132 0.153 0.245 0.288 0.288 1.161Unknown7440-70-2 CalciumMETAL mg/kg 5 7 71% 408.000 409.000 1020.000 8860.000 2769.786 3328.144 5213.924 81260.741 81260.741 1.202 Lognormal7440-47-3 ChromiumMETAL mg/kg7 7 100%NANA 1.600 126.000 20.843 46.400 54.918 343.648 343.648 2.226Unknown7440-48-4 CobaltMETAL mg/kg7 7 100%NANA 0.670 3.100 1.604 0.974 2.320 2.970 2.970 0.607 Lognormal7440-50-8 CopperMETAL mg/kg7 7 100%NANA 4.400 36.700 12.471 11.053 20.589 28.334 28.334 0.886 Lognormal57-12-5 Cyanide, TotalMETAL mg/kg2 7 29% 0.120 0.120 0.120 0.310 0.104 0.093 0.173 0.208 0.173 0.896Unknown7439-89-6 IronMETAL mg/kg 7 7 100% NA NA 3460.000 14500.000 6971.429 4216.469 10067.940 12120.973 12120.973 0.605 Lognormal7439-92-1 LeadMETAL mg/kg7 7 100%NANA 7.500 558.000 98.843 203.552 248.329 2322.450 2322.450 2.059 Lognormal7439-95-4 MagnesiumMETAL mg/kg 7 7 100% NA NA 136.000 865.000 301.286 259.700 492.005 621.427 621.427 0.862 Lognormal7439-96-5 ManganeseMETAL mg/kg7 7 100%NANA 17.700 379.000 111.257 128.152 205.370 622.477 622.477 1.152 Lognormal7439-97-6 MercuryMETAL mg/kg2 7 29% 0.060 0.060 0.100 0.130 0.054 0.042 0.085 0.115 0.085 0.781UnknownFrequency of DetectionRange of DetectionLimitsRange of DetectedConcentrationsTable 3-3Surface Soil Analytical Results (Current Above Ground Storage Tanks)5/5/2003: 4:02 PMState Marine Soil Summary Tables -

Likewise, if the DT was lognormal then the dataset came from a lognormally distributed population.5/5/2003: 5:01 PMState Marine Soil Summary Tables - Ecological.xls: Tables 3-5 and 5-5CASRN ConstituentData Group UnitsArithmeticAverageStandardDeviation95%UCL(Normal)95%UCL(Lognormal) 95%UCLCoefficient ofVariation Distribution Type92-52-4 1,1'-BiphenylBNA mg/kg 2 7 29% 0.430 4.400 0.018 0.210 0.475 0.765 1.036 8.760 8.760 1.611Unknown91-57-6 2-MethylnaphthaleneBNA mg/kg 6 7 86% 0.430 0.430 0.024 1.600 0.488 0.697 1.000 59.497 59.497 1.429Lognormal106-44-5 4-Methylphenol (p-Cresol) BNA mg/kg 1 7 14% 0.420 4.400 0.110 0.110 0.488 0.756 1.043 1.730 1.730 1.550Unknown83-32-9 AcenaphtheneBNA mg/kg 1 7 14% 0.420 4.400 0.064 0.064 0.481 0.760 1.040 2.349 2.349 1.579Unknown208-96-8 AcenaphthyleneBNA mg/kg 7 7 100% NA NA 0.036 0.910 0.313 0.380 0.592 6.903 6.903 1.214Lognormal98-86-2 AcetophenoneBNA mg/kg6 7 86% 0.450 0.450 0.023 0.250 0.147 0.106 0.225 0.923 0.225 0.716Unknown120-12-7 AnthraceneBNA mg/kg7 7 100%NANA 0.031 1.100 0.322 0.443 0.647 9.134 9.134 1.378Lognormal100-52-7 BenzaldehydeBNA mg/kg 5 7 71% 0.450 4.400 0.021 0.097 0.378 0.807 0.971 15.153 15.153 2.132Lognormal56-55-3 Benzo(a)anthraceneBNA mg/kg4 7 57% 0.430 4.400 0.030 4.200 1.032 1.592 2.201 110.272 110.272 1.543Lognormal50-32-8 Benzo(a)pyreneBNA mg/kg6 7 86% 4.400 4.400 0.046 5.100 1.143 1.910 2.546 199.136 199.136 1.671Lognormal205-99-2 Benzo(b)fluoranthene BNA mg/kg 7 7 100% NA NA 0.063 7.100 1.171 2.620 3.094 65.211 65.211 2.238Unknown191-24-2 Benzo(g,h,i)peryleneBNA mg/kg6 7 86% 4.400 4.400 0.059 2.100 0.735 0.972 1.449 18.749 18.749 1.322Lognormal207-08-9 Benzo(k)fluoranthene BNA mg/kg5 7 71% 0.470 4.400 0.023 2.500 0.739 1.106 1.551 152.082 152.082 1.498Lognormal117-81-7bis(2-Ethylhexyl)phthalateBNA mg/kg5 7 71% 2.000 4.400 0.094 1.900 0.822 0.899 1.482 14.215 14.215 1.095Lognormal85-68-7 ButylbenzylphthalateBNA mg/kg 1 7 14% 0.420 4.400 0.024 0.024 0.586 0.778 1.157 13.462 13.462 1.326Lognormal86-74-8 CarbazoleBNA mg/kg2 7 29% 0.430 4.400 0.038 0.520 0.522 0.753 1.075 4.792 4.792 1.444Lognormal218-01-9 ChryseneBNA mg/kg6 7 86% 4.400 4.400 0.039 5.400 1.170 2.022 2.655 294.082 294.082 1.729Lognormal53-70-3 Dibenz(a,h)anthracene BNA mg/kg5 7 71% 0.470 4.400 0.022 0.940 0.514 0.811 1.110 57.153 57.153 1.579Lognormal132-64-9 DibenzofuranBNA mg/kg2 7 29% 0.430 4.400 0.017 0.130 0.463 0.770 1.029 9.438 9.438 1.662Lognormal84-74-2 Di-n-butylphthalateBNA mg/kg1 7 14% 0.420 4.400 0.056 0.056 0.589 0.775 1.158 5.187 5.187 1.314Lognormal117-84-0 Di-n-octylphthalateBNA mg/kg1 7 14% 0.430 4.400 0.013 0.013 0.587 0.778 1.158 34.104 34.104 1.325Lognormal206-44-0 FluorantheneBNA mg/kg7 7 100%NANA 0.029 7.600 1.164 2.840 3.250 262.973 262.973 2.440Unknown86-73-7 FluoreneBNA mg/kg2 7 29% 0.430 4.400 0.029 0.180 0.472 0.765 1.034 4.802 4.802 1.621Lognormal193-39-5 Indeno(1,2,3-cd)pyrene BNA mg/kg7 7 100%NANA 0.038 2.200 0.478 0.799 1.065 19.495 19.495 1.674Lognormal91-20-3NaphthaleneBNA mg/kg6 7 86% 0.430 0.430 0.023 1.400 0.312 0.496 0.677 11.547 11.547 1.588Lognormal85-01-8 PhenanthreneBNA mg/kg7 7 100%NANA 0.017 2.000 0.477 0.779 1.048 84.246 84.246 1.634Lognormal129-00-0 PyreneBNA mg/kg7 7 100%NANA 0.042 7.400 1.273 2.723 3.273 185.491 185.491 2.139Lognormal7429-90-5 AluminumMETAL mg/kg7 7 100%NANA 3500.000 6780.000 4845.714 1088.927 5645.406 5817.782 5645.406 0.225Normal/Lognormal7440-36-0 AntimonyMETAL mg/kg2 7 29% 0.650 0.680 1.400 4.600 1.091 1.598 2.265 5.420 5.420 1.464Unknown7440-38-2 ArsenicMETAL mg/kg7 7 100%NANA 4.100 26.400 8.614 7.877 14.399 16.241 14.399 0.914Unknown7440-39-3 BariumMETAL mg/kg7 7 100%NANA 64.500 289.000 128.814 81.424 188.611 228.710 228.710 0.632Lognormal7440-41-7 BerylliumMETAL mg/kg5 7 71% 0.310 0.550 0.120 0.680 0.441 0.249 0.625 1.182 0.625 0.565Normal/Lognormal7440-43-9 CadmiumMETAL mg/kg3 7 43% 0.160 0.340 0.660 1.700 0.605 0.681 1.105 7.804 7.804 1.126Lognormal7440-70-2 CalciumMETAL mg/kg 7 7 100% NA NA 3000.000 17500.000 8200.000 5578.647 12296.874 18937.431 12296.874 0.680 Normal/Lognormal7440-47-3 ChromiumMETAL mg/kg7 7 100%NANA 6.500 503.000 80.371 186.383 217.248 1416.567 1416.567 2.319Unknown7440-48-4 CobaltMETAL mg/kg7 7 100%NANA 3.000 19.100 6.600 5.618 10.726 12.963 10.726 0.851Unknown7440-50-8 CopperMETAL mg/kg7 7 100%NANA 10.800 7390.000 1076.014 2784.239 3120.717 794913.816 794913.816 2.588Unknown7439-89-6 IronMETAL mg/kg 7 7 100% NA NA 8470.000 ######### 31010.000 45590.423 64490.922 104949.225 104949.225 1.470Unknown7439-92-1 LeadMETAL mg/kg7 7 100%NANA 23.500 1030.000 190.743 370.682 462.966 1508.711 1508.711 1.943Unknown7439-95-4 MagnesiumMETAL mg/kg 7 7 100% NA NA 720.000 1500.000 1157.143 247.232 1338.707 1414.776 1338.707 0.214 Normal/LognormalFrequency of DetectionRange of DetectionLimitsRange of DetectedConcentrationsTable 3-6Surface Soil Analytical Results (Former Lauren Tank Farm)5/5/2003: 4:59 PMState Marine Soil Summary Tables -

# 4. DEVELOPMENT OF SCRE ENING BENCHMARK VALUES

An important step in ecological risk assessment is screening the chemicals occurring on a site for

constituents of potential ecological concern (COPEC). Screening may be accomplished by

comparing reported concentrations in media to a set of toxicological benc hmarks. In general,

ecological screening benchmark va lues (SBVs) are chemical conc entrations that correspond to

fixed levels of risk. If a chem ical concentration exceeds the SBV, more analysis is needed to

determine the hazards posed by that chemical and it is labeled a COPEC. If, however, the

chemical concentration or its detection limit fall s below the SBV, the chemical may be ignored

during further study unless public concern or ancillary evidence suggests that it should be

retained.

This section presents specific information on how the screening levels used in this SRA were

calculated. SBVs should genera lly be consistent with the exposure pathways and exposure

routes as outlined in the Site Conceptual Model for ecological receptors and exposure as

presented in Figure 3-1. Screen ing benchmarks are summarized in the sections below according

to the media for which they were developed and are presented in detail in Tables 4-1 through 4-

8.

4.1 SOIL

No regulatory criteria or standard s have been established for soil. Soil chemical concentrations

are compared to soil SBVs to assess the toxi city of COPECs to terrestrial plants and

soil-dwelling organisms through direct contact and to wildlife through bioaccumulation through

the terrestrial food chain. Multiple SBVs are pr esented for soil to help portray the entire

spectrum of concentrations that have been as sociated with various probabilities of adverse

biological effects. SBVs for soil are presented in Table 4-1. The ecological SBV that was

selected for soil is the lowest of all the values presented. These conservative SBVs are then

compared to Texas-specific median bac kground concentrations [Figure 30 TAC 350.51(m)]

since it is safe to assume that a benchmark below background is a poor measure of ecological

risk (TCEQ, 1999).

# 4-2 Ecological benchmarks for earthworms and terrestrial plants recommended by the Texas

Commission on Environmental Quality (TCEQ) were also considered as SBVs (TCEQ, 2001).

The TCEQ benchmarks were selected from a co mpendium of benchmarks from a variety of

literature sources, including toxicological be nchmarks from Oak Ridge National Laboratory

(ORNL) and EPA ecological soil screening levels.

EPA guidance (EPA, 2000a) provides a set of risk-based soil screening levels (Eco-SSLs) for

many of the soil contaminants that are frequently of ecological concern fo r terrestrial plants and

animals at hazardous waste sites. These Eco SSLs ar e concentrations of cont aminants in soil that

are protective of ecological recepto rs that commonly come into cont act with soil or ingest biota

that live in or on soil. Eco-SSLs are derived se parately for four groups of ecological receptors:

plants, soil invertebrates, birds and mammals. As such, these va lues are presumed to provide

adequate protection of terrestrial ecosystems (EPA, 2000). Twenty-four contaminants are

initially addressed by the Eco-SSL guidance, including 17 metals a nd seven organics. Note that

the Eco-SSLs are not designed to be used as cleanup levels.

Terrestrial assessments are one of the least deve loped aspects of ecological risk assessment and

EPA has drafted limited screening values for th is component (EPA, 2001). As an additional

source EPA has recommended soil screening va lues developed by Friday et. al., for the

Savannah River Technology Center (1998). These screening values are a summary of screening

values from a variety of sources a nd are also presented in Table 4-1.

ORNL has developed toxicological benchmarks for screening COPE Cs for effects on ecological

receptors. Toxicity of selected chemicals to soil and litter dwelling invertebrates, microbes,

microbial processes, and terrestrial plants was obtained from database a nd literature searches.

Reports of toxicity tests of individual chemicals in laboratory, greenhouse, or field settings were

obtained. The toxicity benchmarks were deri ved by rank-ordering the lowest observed effect

concentrations (LOECs) and picking a number approximating the 10 th 

# percentile. If there were

10 or fewer values for a chemical, the lowest LOEC was used. Proposed screening benchmarks

were developed for toxic effects of contaminants in soils to earthworms, microbial processes,

and terrestrial plants (Efroymson et al., 1997a; Efroymson et al., 1997b, Sample et. al., 1998).

H:\STATE MARINE\RI REPORT (FINAL)\APPENDIX D (E COLOGICAL RISK ASSESSMENT)\TEXT\ECORA.DOC 5/8/03



# 4-3 In addition, ORNL has derived wildlife prelim inary remediation goals (PRGs) for soil by

iteratively calculating exposure estimates using different soil c oncentrations and soil-to-biota

contaminant uptake models (Efroyms on et al., 1997c). The soil co ncentrations were manipulated

to produce an exposure estimate equivalent to the wildlife endpoint-specific and contaminant

specific lowest observable adverse effect level (LOAEL). PRGs were developed for six species:

short-tailed shrew, white-footed mouse, red fox, white-tailed deer, American woodcock, and redtailed hawk. For each chemical, the PRG for each of the wildlife species was compared, and the

lowest value was selected as the final wildlife PRG.

EPA Region 6 has developed terrestrial plant and soil invertebrate toxicity reference values

based on bulk soil exposures (EPA, 1999a). Availa ble terrestrial plant toxi city reference values

and soil invertebrate toxicity values from the scie ntific literature were used to develop Toxicity

Reference Values (TRVs). If no toxicity va lue was available for a COPEC, the TRV for a

surrogate COPEC was adopted.

4.1.1 Site-Specific Background

Background screening values were derived for natu rally occurring inorganics using site-specific

background soil samples. Three surface soil locations (SM133, SM134, and SM135) were

sampled adjacent to the SMS Site and analyzed for metals to calculate site-specific background

concentrations (see Figure 3-3). Only those metals that were detected from at least one of the

three locations were calculated as background and included in this assessment as screening

values for soil. Site-specifi c background concentrations were calculated using the arithmetic

mean for constituents with 100% frequency of dete ction or the maximum detected concentration

for constituents with a frequency of detection le ss than 100%. Four metals, antimony, cadmium,

selenium, and thallium, were not detected at any of the background locations. The arithmetic

mean and the maximum detected concentration we re used for the background calculation instead

of a more statistically robust calculation because of the limited sample size (n = 3). A complete

summary of analytical data for bac kground soil is presented in Table 3-10.

# 4-4 4.2 SEDIMENT

The comparison of concentrations to sediment be nchmarks is the initial step in the sediment

quality triad approach, where the intensity and extent of exposure to chemical stressors are

evaluated using three measures of exposure, including sediment chemistry data, porewater

chemistry data, and tissue chemistry data (CDM, 2001).

No regulatory criteria or standard s have been established for sediments. Sediment chemical

concentrations are compared to sediment SBVs to assess the toxicity of COPEC to benthic and

epibenthic life (i.e., organisms that live on or within the sediments). Multiple screening

benchmark values are presented to help portray th e entire spectrum of conc entrations that have

been associated with various prob abilities of adverse biological e ffect. Focus was given first to

the effects-range low (ER-L) values as the most appropriate no effect leve l screening criteria and

then to other values such as the median effects level (ER-M) values as an appr opriate second tier

comparison. SBVs for sediment are presented in Table 4-2.

The EPA has been conducting an RI/FS for the Cal casieu Estuary, which is in close proximity to

the SMS Site and provides very similar habita t to Sabine Lake (CDM, 2000a, 2000b). In the

Calcasieu Estuary Investigation, numerical e ffects-based sediment quality guidelines (SQGs)

were selected from available literature-based SQ Gs for the protection of aquatic life. The SQGs

for marine/estuarine systems include ER-M va lues developed by Long et al. (1995), marine

Probable Effects Levels (PELs) from MacDonald et al. (1996), and freshwater Probable Effect

Concentrations (PECs) from MacDonald et al. (2000). These reco mmended SQGs were

considered as sediment SBVs for the SMS Site. Since the constituents of potential concern at the

Calcasieu Estuary were not the same as those de tected at the SMS Site, and not as conservative

as no-effect levels, additional sediment benchmar ks were considered as SBVs for the SMS Site

as discussed below.

NOAA has compiled a set of Screening Quick Reference Tables (SquiRTs) that present

screening concentrations for various inorga nic and organic contaminants in several

environmental media including sediment (Buchm an, 1999). For sediments, multiple benchmark

concentrations are presented by Buchman to help portray the entire spectrum of concentrations

that are associated with various probabilities of adverse biological effects for both freshwater and

# 4-5 marine systems. This spectrum ranges from presumably nontoxic to highly toxic levels. NOAA

has also developed a data query manager that al lows review of environm ental data compiled for

various sites (2002). The sediment benchmark values that are su mmarized in SQuiRT are also

listed in part by the NOAA query manager. For constituents not listed by the query manager,

ER-L, ER-M, PEL, and PEC, values were obtained from the NOAA SQuiRT.

Ecological benchmarks for both freshwater an d marine sediment recommended by the TCEQ

were also considered as SBVs (2001). Th e TCEQ benchmarks were selected from a

compendium of sediment benchmarks from a variety of sources including NOAA ER-L and

ER-M values.

4.2.1 Site-Specific Background

Background screening values were derived for naturally occurring inorganics in sediment using

site-specific background samples. Five su rface sediment locati ons (RF001, RF002, RF003,

RF004, and RF005) were sampled directly adjacent to Sydnes Island (1 mile east of Pleasure

Islet) and analyzed for metals for the purpos es of calculating site-specific background

concentrations (see Figure 3-3). Only those metals that were detected from at least one of the

five locations were calculated as background and in cluded in this assessment as screening values

for sediment. Site-specific background values for sediment were calcu lated using either the

arithmetic mean for constituents with 100% fre quency of detection or the maximum detected

concentration for constituents with less than 100% frequency of detection. Five metals, copper,

selenium, silver, thallium, and cyanide, were no t detected at any of th e background locations.

Tributyltin was detected at all 5 background locatio ns but not calculated as a screening value for

background because anthropogenic sources of this contaminant are high in and around Pleasure

Islet. The arithmetic mean and the maximum de tected value were used in the derivation of

background concentrations instead of a more statistically r obust calculation because of the

limited sample size (n = 5). A complete summary of analytical data for background sediment is

presented in Table 3-16.

# 4-6 4.3 GROUNDWATER

The range of detected concentrations in groundw ater and surface water were compared to Texas

Water Quality Standards (TWQS) [TCEQ, 1997]. Groundwater or surface water SBVs that were

not available from the TWQS fo r a particular constituent were based on the lowest or most

conservative of the following values:

 Federal Ambient Water Quality Criter ia (AWQC) (40 CFR 131.36) [EPA, 1996].

 Tier II Secondary Chro nic Values (Suter, 1996).

For certain chemicals where sufficient informa tion was unavailable to calculate an AWQC, the

Federal Standards LOAELs were used (EPA, 1999b). Office of Solid Waste and Emergency

Response (OSWER) Tier II Values , as taken from ORNL documen tation, were used when no

information from the TWQS or the AWQC was avai lable. Constituents that did not have water

quality benchmarks were identified in the co mparison results tables. The lowest of the

groundwater SBVs selected were multiplied by 10 to achieve a dilution factor appropriate for

assessing the potential impact to surface waters in Lake Sabine from the groundwater. This

approach was discussed with NOAA’s Coastal Resource Manager, Ron Gouguet, during work

plan and scoping meetings on the SMS Site as an approach to assessi ng possible ecologically

related groundwater to surface water impacts. Th e appropriate reference for this approach was

cited from the NOAA SQuiRTs (Buchman, 1999). The SBVs for groundwater are presented in

Table 4-3.

4.4 WILDLIFE

Using standard food-chain modeling methodology and information from TCEQ (2001) and EPA

(1999a) for constituents considered to be bioaccumulative in aquatic and terrestrial

environments, SBVs were developed by back calc ulating soil or sediment concentrations that

would be equivalent to acceptable ecological exposur e levels for selected species of wildlife.

These selected species are called measurement recep tors and are assumed to be representative of

other species with similar feed ing guilds and life histories.

Discussion on the selection of bioaccumulative constituents, measurement receptors, exposure

parameters, biota accumulation factors (BAF s), and TRVs is presented as follows:

SBVs for each measurement receptor are derived in Tables 4-4 through 4-7. A summary of the

SBVs for all the measurement receptors is presented in Table 4-8.

4.4.1 Determine Bioaccumulative COPEC

Only those COPEC that were considered to be bioaccumulative in soil and sediment were

considered in the development of food-chain SBVs. The bioaccumulative COPEC for soil and

sediment were developed using the informati on on bioaccumulative chemicals as presented in

Section 3.4, Identification and Evaluation of Bioaccumulative Chemicals and Table 3-1 of the

Texas Ecological Risk Assessment Guidance (TCEQ, 2001). Those bioaccumulative COPEC

that were detected in sediment or soil at the SMS Site can be summarized as follows:

Cadmium X X

Chromium X --

Copper X X

Lead X

--

Nickel X X

Mercury X X

Selenium X X

Zinc X X

Tributyltin -- X

Food-chain SBVs were not developed for severa l COPEC as listed by TCEQ because they were

not sampled during this investigatio n of the SMS Site. A review a nd screening of historical data

concluded that these “other” constituents were present at very low concentration and not siterelated. Additional constituents that were not present based on this information included the

organochlorine pesticides, poly- chlorinated bipheryl s (PCBs), dioxin/furans, and some other

semi-volatiles.

# 4-8 4.4.2 Select Measurement Receptors

Two avian species of w ildlife (spotted sandpi per, belted kingfisher), representing the carnivorous

shore bird feeding guild in the freshwater/ wetland and estuarine/wetland food webs, were

selected as measurement receptors for the off-s ite sediments. The spotted sandpiper was an

appropriate receptor for assessing potential expo sure to bioaccumulative contaminants primarily

in the intertidal sediment through ingestion of benthic macroinvertebrates. The kingfisher was

appropriate for assessment potenti al exposure to the nearshore and offshore sediments through

ingestion of small and medium sized fish.

One avian species of wildlife (Northern bobwhite quail), representing the omnivorous bird

feeding guild in the Texas shrub/scrub food we b, and one mammalian species of wildlife (whitefooted mouse), representing the omnivorous ma mmal feeding guild in the Texas shrub/scrub

food web, were selected as measurement receptors for the uplands soils. The bobwhite and the

mouse were appropriate receptors for asse ssing potential exposure to bioaccumulative

contaminants in the upland source areas thr ough the ingestion of pl ants and terrestrial

invertebrates. The selection of a bird and mammal covers any potential for difference in

toxicological sensitivity between the two receptors.

While the presence of these receptors has not been directly established (through observations)

on-site or off-site, their habitat ranges cover co astal southeast Texas and Lake Sabine including

wetland and scrub/shrub habitat on and adjacent to the SMS Site. In addition to preference of

habitat, the selected receptors have readil y available exposure information and are also

recommended as measurement receptors by both the EPA (1999a) and TCEQ (2001).

COPEC exposure to terrestrial w ildlife occurs primarily when animals take up bioaccumulative

constituents while feeding in areas impacted by site contamination. The species selected as

measurement receptors represent a range of feedi ng relationships that ar e consistent with the

principal habitats present at the site. It is also important to note that these receptors were

selected to represent exposures other (similar) sp ecies with comparable feeding guilds and life

histories may be receiving, and thus, serve as “surrogate” receptors to others within the

ecosystem.

# 4-9 The presence of threatened and endangered specie s, their feeding and migratory behaviors, and

their preferred habitats were also considered in the selection of measurement receptors for the

SMS Site. Several federal and state endangere d and threatened avian and mammalian species

were reported during a database search by the W ildlife Management agencies for the SMS Site

(see Attachment C). Listed small mamma ls include the Mexi can long-nosed bat ( Leptonycteris

nivalis ) and the eastern big-eared bat ( Plecotus rafinesquei ). Listed songbirds include the blackcapped vireo ( Vireo atricapillus ), golden-cheeked warbler ( Dendroica chrysoparia ),

southwestern willow flycatcher ( Empidonax traillii extimus ), and Bachman’s sparrow

( Aimophila aestivalis ). Listed shorebirds and waterbirds include the white-faced ibis ( Plegadis

chichi ), Eskimo curlew ( Numenius borealis ), wood stork ( Myceria americana ), and the piping

plover ( Charadrius melodus ) (TPWD, 2001; USFWS, 1994, 1995).

Although none of these species were selected as measurement receptors for the SMS Site, the

exposure and toxicity assigned to the receptors that were selected is considered to be protective

of all species with similar feeding guilds and life histories, including species of special status.

The criteria used in selecting measurement r eceptors was primarily based on the presence and

abundance of appropriate habitat and food associat ed with the SMS Site. Further discussion

regarding the selection of measurement receptors a nd species of special status is presented below

as well as in Attachment C.

4.4.2.1 Northern Bobwhite

The Northern bobwhite ( Colinus virginianus ) was selected as a measurement receptor for the

omnivorous bird feeding guild in the Texas shrub/scrub food web. The proposed Northern

bobwhite SBVs are derived in Table 4-4 and summarized in Table 4-8. The bobwhite was

chosen as a measurement receptor based on the following information (EPA, 1999a; TCEQ,

2001):

 The bobwhite plays an important role in seed dispersion for many plant species, and

is an important prey item for snakes, and other small mammals. If habitat conditions

permit, their numbers will increase rapidl y, providing an additional food source for

many predators. They are also valuable in controlling ins ect populations during

certain times of the year.

# 4-10  The bobwhite’s diet consists mainly of seeds and invertebra tes, although in the

winter, green vegetation can dominate its diet. During breeding season, the

bobwhite’s home range may encompass seve ral hectares, including areas for foraging,

cover, and a nest site. In non-breeding season, the bobwhite’s hom e range can be as

large as 16 hectares. It has a high potential for exposure th rough ingestion and

dermal contact with soil during dust bathing.

 The availability of natural history/t oxicological information (e.g., home range

ingestion rates, body weights, TRVs) al so support selection as a measurement

receptor.

Several listed songbird species occur in the vicinity of the SMS Site . None of these species were

selected as a measurement species for the shrub/sc rub habitat because of inappropriate habitat or

lack of appropriate food supply. The following is a brief description of these species:

 Black-capped vireos nest in Texas during Ap ril through July, and sp end the winter on

the western coast of Mexico. They build a cup-shaped nest in the fork of a branch

2 to 4 ft above the ground. Nests are usually built in shrubs such as shin oak or

sumac. Vireos feed on insects and inhabit rangelands with scattere d clumps of shrubs

separated by open grassland (TPWD, 1999).

 Bachman’s sparrow is an uncommon spa rrow found in the open pine woods and

brushy fields of east Texas. It is secretiv e and difficult to locate in the winter; in the

summer it perches in the open and sings. This sparrow eats seeds of herbaceous

plants and pines, and insects. They do mo st of their foraging on the ground (Sarkozi,

1996).

 The southwestern willow flycatcher ( Empidonax traillii extimus ) is a small

insectivorous bird th at breeds in dense riparian ha bitats across the southwestern

United States (USFWS, 2002).

 Golden-cheeked warblers nest only in cen tral Texas in mixed ashe-juniper and oak

woodlands in ravines and canyons. Warble rs eat insects and spiders found on the

leaves and bark of oaks and other trees. Th ey use long strips of cedar bark and spider

webs to build their nests. They come to Texas in March to nest and raise their young,

and leave in July to spend the winter in Mexico and Central America (TPWD, 1999).

4.4.2.2 Spotted Sandpiper

The spotted sandpiper ( Actitis macularia ) was selected as a measurement receptor for the

carnivorous shore bird guild in the Texas fres hwater wetland and brackish/intermediate food

webs. The proposed spotted sandpiper SBVs are derived in Table 4-5 a nd summarized in Table

# 4-11 4-8. The spotted sandpiper wa s chosen as a measurement re ceptor based on the following

information (EPA, 1999a; TCEQ, 2001):

 The spotted sandpiper inhabits a wide variet y of habitats usually associated with

water or marsh. Spotted sandpipers ha ve a high potential fo r exposure through

ingestion of aquatic insects, worms, fi sh, crustaceans, mollusks, and carrion.

 The availability of natural history information (e.g., home range, ingestion rates, body

weights, TRVs) also supports selection as a measurement receptor.

Several listed shorebird species occur in the vicinity of the SMS Site. None of these species

were selected as a measurement species for th e freshwater wetland and brackish/intermediate

habitats because of inappropriate habitat or lack of appropriate food supply. The following is a

brief description of these species:

 Piping plovers eat marine worms, flies, b eetles, spiders, crustaceans, mollusks and

other small marine invertebrates. They inhabit sandy beaches and lakeshores,

migrating through the Great Lakes along th e river systems through the Bahamas and

West Indies. Currently found along the At lantic Coast from Canada to North

Carolina and along the shorelines of Lakes Mi chigan and Superior in Michigan. They

spend the winter along the Gulf Coast b eaches from Florida to Mexico, and the

Atlantic coast from Florida to North Carolina (TPWD, 1999).

 The Eskimo curlew is thought to be very close to ex tinction. They feed on

grasshoppers, grasshopper eggs, grubs, and cutworms, while inhabiting a variety of

grassland areas. The curlew migrates fr om breeding grounds across the Arctic tundra

through North American prairies to winter ing grounds on the Pampas grasslands of

Argentina (TPWD, 1999).

 The white-faced Ibis seems to prefer freshwater marshes where it can find insects,

newts, leeches, earthworms, snails and esp ecially crayfish, frogs and fish. The Ibis

roosts on low platforms of dead reed stems or on mud banks (TPWD, 1999).

 Wood storks are wetland dwellers and use fresh, brackish, and salt-water habitats for

feeding and nesting. Feeding takes place in shallow ponds, tidal pools, swamps, and

marshes. Nesting occurs in cypress, hardwood, and mangrove swamps. Standing in

6 to 20 in. (15 to 51 cm) of water with its s ubmerged beak open 2 to 3 in. (5 to 8 cm),

the wood stork gropes for its prey. This usually consists of fish, occasionally crayfish

and amphibians, baby alligators , and snakes (Mazzotti, 1999).

# 4-12 4.4.2.3 Belted Kingfisher

More so than any other type of wildlife, a pisc ivore would generally have the greatest potential

of exposure to contaminants in the aquatic environment via food-chain uptake. Based on its

widespread distribution, relatively low body weight, exclusive diet of fish, and frequent inclusion

in assessments of aquatic ecosystems, the belted kingfish ( Ceryle alcyon ) was selected as a

measurement receptor for screening off-site sedime nts at the SMS Site. The belted kingfisher is

assumed to represent other species of carnivorous shore birds that feed exclusively on fish from

the highest trophic level as shown in the fe eding guilds for Texas freshwater/wetland and

estuarine/wetland food webs (TCEQ, 2001). Ca rnivorous shore birds not only provide an

important functional role to th e environment by regulating lower trophic level prey populations

and influencing species composition in terrestrial and aquatic ecosystems, but they also provide

egg dispersal for some fish and aquatic invertebrates.

The belted kingfisher was chosen as a measur ement receptor based on the following speciesspecific information (EPA, 1999a; TCEQ, 2001):

 As a higher trophic level predator, the belted kingfisher provides an important

component to the ecosystem by influenci ng the population dyna mics of its prey.

 The belted kingfisher is found statewide along rivers, streams, lakes, ponds, coasts,

and estuaries. Its diet consists of mostly fish that swim near the surface or in shallow

water. It nests in burrows in earthen banks , generally near suitabl e fishing areas. Its

home range is measured in shoreline length and averages approximately

1.5 kilometers. Due to its dietary habits and relatively small bodyweight, there is a

high potential for exposure.

 The availability of natural history/t oxicological information (e.g., home range,

ingestion rates, body weights, TRVs) al so support selection as a measurement

receptor.

The proposed belted kingfisher food-chain SBVs are derived in Table 4-6 and summarized in

Table 4-8.

4.4.2.4 White-Footed Moose

The white-footed mouse ( Peromyscus polionotus ) was selected as the measurement receptor for

the omnivorous mammal guild in the Texas sh rub/scrub food web. The proposed white-footed

H:\STATE MARINE\RI REPORT (FINAL)\APPENDIX D (E COLOGICAL RISK ASSESSMENT)\TEXT\ECORA.DOC 5/8/03



# 4-13 mouse SBVs are presented on Table 4-7 and summ arized in Table 4-8. The white-footed mouse

was selected as a measurement receptor ba sed on the following information (EPA, 1999a;

TCEQ, 2001):

 The white-footed mouse plays an important role in seed disper sal and provides an

important food source for raptors, sn akes, and other mammals including cats,

weasels, and fox.

 The white-footed mouse feeds on nuts, seeds, fruits, beetles, caterpillars, and other

insects. Due to its burrowi ng and dietary habits, there is a high potential for direct

and indirect exposure.

 The availability of natural history information (e.g., home range, ingestion rates, body

weights, TRVs) also supports selection as a measurement receptor.

Two listed small mammals species (the MexicanLong-nosed Bats and the Rafinesque’s bigeared bat) occur in the vicinity of the SMS Site . Neither of these species was selected as a

measurement species for the shrub/scrub habitat because of inappropriate locale or lack of

appropriate food supply. The following is a brief description of these species:

 During the day, Mexican Long-nosed Bats roost in caves in large groups called

colonies. Strong fliers that can hover like hummingbirds, these bats come out at night

to feed on the nectar and pollen in flowers of desert plants such as agaves. With long

noses and tongues, they are well-adapted fo r nectar-feeding. Th ey also help the

agave plants reproduce by spreading pollen. The bats migrate between Big Bend and

southern Mexico following the bloom pe riods of food plants (TPWD, 1999).

 Rafinesque’s big-eared bats occur in forest ed regions largely devoi d of natural caves.

Its natural roosting places are in hollow tr ees, crevices behind bark, and under dry

leaves. It has been observed most frequently in buildings, both occupied and

abandoned. Texas specimens have been captured in barns and abandoned wells.

Specific food items have not been recorded but small, night-flying insects, especially

moths, are probably important. The bats probably do not hi bernate in East Texas, but

in the northern part of their range they tend to seek out underground retreats and

hibernate through the winter (Davis and Schmidly, 1994).

4.4.3 Input Exposure Parameters

All exposure parameters (i.e., sediment intake rates, food ingestion ra tes, tissue moisture

contents, and body weights) were obtained from EPA (1999a orb) and TCEQ (2001). The

exposure parameters are based on the assumption th at all receptors spend 100% of their lifetime

in contaminated areas and consume 100% of thei r prey from contaminated areas. The white# Weston Solutions, Inc. – Final Ecological Screening Risk Assessment

DEVELOPMENT OF SCREENING BENCHMARK VALUES

H:\STATE MARINE\RI REPORT (FINAL)\APPENDIX D (E COLOGICAL RISK ASSESSMENT)\TEXT\ECORA.DOC 5/8/03



# 4-14 footed mouse and Northern bobwhite quail are assumed to consume diets of 50% terrestrial

plants and 50% terrestrial invertebrates. A sa ndpiper is assumed to consume a diet of 100%

aquatic invertebrates and a kingfis her is assumed to eat 100% fish. Plant, invertebrate, and fish

tissue residues are predicted thr ough the use of BAFs from soil and sediment as discussed in

detail in Section 4.4.4.

Bioavailability is a ratio of concentrations; th e concentration of a contaminant that reaches a

point of toxic action in an or ganism over the concentration of that contaminant in the

environmental media that the organism first contacts (TCEQ, 2001). Uptake and elimination

rates of the bioavailable form of a contaminant are important factors since the combined effects

of these factors determine whether the material is accumulated or eliminated. Bioavailability is

the cumulative expression of physical, chemical, a nd biological processes ev ident in air, water,

soil, and sediment, as well as biological factors present in the bodies, orga ns, tissues, or cells of

exposed organisms that act to change that organi sm's rate of contaminant exposure. A default

value of 100% was used for soil and sediment bioa vailability ratios (meaning a one to one ratio).

4.4.4 Bioaccumulation Factors

A bioaccumulation factor (BAF) is the ratio of the concen tration of a contaminant in an

organism to the concentration in the ambient e nvironment at steady state, where the organism

can take in the contaminant through ingestion of food as well as through direct contact. A biotasediment accumulation factor (BSAF) is a specific form of BAF equivalent to the ratio of a lipidnormalized tissue residue and an organic carbon normalized sedi ment concentration (TCEQ,

2001). A bioconcentration factor (BCF) is the ratio of the concentration of a contaminant in an

organism to the concentration in the ambient e nvironment (typically wa ter) at steady state.

These terms are used interchangeably.

For this part of the screening evaluation, sedi ment accumulation factors used to predict the

uptake of contaminants from sediment into fish tissue will be called BSAFs. This includes both

organic constituents, (using the normalization processes discussed above) and inorganic

constituents, which are based on ratios of the fi sh tissue and sediment concentrations without

lipid or organic carbon normalization. BSAFs were used to predict the uptake of constituents

# Weston Solutions, Inc. – Final Ecological Screening Risk Assessment

DEVELOPMENT OF SCREENING BENCHMARK VALUES

H:\STATE MARINE\RI REPORT (FINAL)\APPENDIX D (E COLOGICAL RISK ASSESSMENT)\TEXT\ECORA.DOC 5/8/03



# 4-15 from soil into plant and terrestrial invertebrate tissues. No normalization was used on the BAFs

derived for soil-to-plant a nd soil-to-invertebrates.

4.4.4.1 Sediment

BSAFs account for the transfer of chemicals specifi cally from the sediment to the tissues of an

organism and are recommended for modeli ng nonpolar organics including dioxin-like

compounds and polychlorinated biphenyls because of their lipophilic nature (EPA, 1998).

BSAFs for fish/sediment were based on high- and low-level bioaccumulation factors derived

from several fish species as available from the Calcasieu Estuary Investigation database. A

focus was made to obtain co-located fish/sediment data which limited the dataset to the EPA

Phase 2 Study. All fish tissue and sediment ch emistry data were initially downloaded from

EPA’s website http://www.epa.gov/earth1r6/6sf/sfsites/datarep.htm and were queried using the

NOAA Query Manager 2.0 software, also downloaded from EPA’s Ca lcasieu Estuary web site.

BSAFs for fish and aquatic invertebrates and details on the methodology for deriving them are

presented in Tables 4-9 and 4-10, respectively. I norganic and organometal (such as tributyltin)

BSAFs were derived without normalizing to lipid and organic carbon becaus e they do not adhere

to the sediment uptake rules th at govern lipophilic organics. BSAFs for these metal and metallike constituents may be more appropriately call ed BAFs because uptake of the chemical into

fish is assumed to occur through pathways othe r than sediment (e.g., food and water) and uptake

of these constituents is not controlled by the orga nic carbon in the sediment nor the lipid content

in the fish.

4.4.4.2 Soil

Tissue residues for plants and terrestrial inverteb rates were predicted from soil concentrations in

the upland area through use of laboratory and field-derived BA Fs obtained from scientific

literature and from regression mode ls based on literature-derived da ta. Uptake factors from EPA

(1999) were primarily used to es timate tissue concentrations from soil. A secondary source of

uptake factors included values from ORNL, th e Bechtel-Jacobs Company (BJC, 1998) and

Sample et al. (1996). Uptake factors are presente d as part of the food-ch ain SBV calculations for

the bobwhite quail and white-footed mouse in Tables 4-4 and 4-7.

# 4-16 4.4.5 Select Toxicity Reference Values

Wildlife TRVs were obtained primarily from EPA ( 1999a). If a TRV was not available from this

source, TRVs were obtained from Sample et al. (1996).

Body scaling parameters (i.e., body mass) were used to estimate a toxic concentration for a class

of organisms (e.g., the toxic dose to mammals). As cited in TCEQ (2001), the endpoint for an

avian or mammalian guild member can be es timated using an equation of the form:

(

# = 1.2 for birds and r 2 

# = 0.94 for mammals were applied from

Sample et al. (1996) in the absence of chem ical-specific scaling factors (TCEQ, 2001).

Wildlife SBVs were developed for no effect leve l TRVs. Uncertainty factors were applied, as

needed, to develop a TRV based on no-observed- adverse-effect level (NOAEL) data. All the

benchmarks for the white-footed mouse and th e Northern bobwhite are proposed as SBVs for

upland soil. All the SBVs for the spotted san dpiper and the belted kingfisher are proposed as

wildlife SBV for off-site sediment.FridaydTNRCC Site-SpecificCASRN ConstituentsEarthworm Plants Plant Invertebrate Avian Mammal EarthwormSoilMicroorganismsPlants WildlifeEcologicalScreening

# 5. CHARACTERIZATION OF RISK SCREENING

The characterization of risk screening iden tifies the magnitude and frequency by which

measurement receptors are exposed to COPEC that have migrated or may potentially migrate

through various exposure pathways to the ecologi cal habitat on and adjacent to the SMS Site.

This involves comparison of site-specific levels of constituents present in environmental media

and food sources to levels considered to be pr otective of environmental receptors including sitespecific quantification of the levels of constituents that may be entering wildlife measurement

receptor through bioaccumulation in the food-ch ain (i.e., Wildlife Food-Chain Benchmarks).

5.1 SUMMARY OF RESULTS

This section contains both a statistical summary of the soil, sediment, and groundwater analytical

results as sampled at the SMS Site and a comp arison of screening benchmarks and background

screening values to average and maximum site concentrations. The primary objective of this

discussion is to summarize the location and exte nt of contamination while determining whether

there is a current or potential futu re risk to ecological receptors.

5.1.1 Soil

The soil investigation was conducted across the entire site in order to determine the extent of soil

contamination associated with identified sour ce and nonsource areas. The source areas for soil

included the following areas: Wastewater Impoundme nt, Wastewater Treatment Facility, Current

Aboveground Storage Tank (AST), Maintenance Shed, Tar Burn, and the Lauren Refining

Company Tank Farm. All soil samples were analyzed for base/neutral/acid (BNAs) and metals.

The average and maximum concentrations for each detected constituent were compared to

literature-based screening benchmar ks (the lowest values that we re available from TCEQ, EPA,

ORNL, and Friday [1998], risk-based food-chain benchmarks for wildlife, and the EPA Region 6

Medium-Specific Screening Levels [MSSLs]. N onrisk-based screening levels for background

were also compared to average and maximum de tected concentrations. Risk-based benchmark

and background screening value comparison results are summarized in the following paragraphs
