Pathways. Components, or Threats Not Scored

1) Ground Water Pathway: The ground water pathway will not be scored, even though an observed release

has been identified. Scoring the surface water pathway alone is sufficient to score the site.

Based on laboratory analytical results from ground water samples collected during the October 1999

Expanded Site Inspection (ESI), several metals were detected at concentrations that exceeded three times

the designated maximum background concentrations (Ref. 9, p. 92).

Thirty-three (33) public, industrial, unknown use, test, and domestic water wells have been identified within

; a four-mile radius of the site (Ref. 9, p. 93). However, the site is slightly elevated along the western

property boundary and gradually slopes toward Sabine Lake. Thus, all ground water wells identified appear

to be located upgradient or cross-gradient of the Palmer site (Ref. 9, p. 82).

2) Soil Exposure Pathway: The soil exposure pathway will not be scored, even though extensive surface and

subsurface contaminated soils have been identified associated with various on-site source areas. Scoring

the surface water pathway alone is sufficient to score the site.

No residents, schools, or day care facilities have been identified on or within 200 feet of any known source

of contamination. While physically accessible to the public, a majority of the site is heavily vegetated with

grasses and small trees (Ref. 9, p. 86). Several Federal and state threatened and endangered species have

been identified as inhabiting areas within a 4-mile radius of the site or within 15 miles downstream of the

site. In addition, two bird rookeries have been identified within the 15-mile Target Distance Limit (TDL)

determined for the site (Ref. 9, p. 87). There are no immediate resources associated with the site, as the

soils on which the site is situated are not suitable for cultivation (Ref. 9, p. 88).

3) Air Pathway: The air migration pathway will not be scored because the necessary data to document an

observed release are not available.

SITE SUMMARY

The Palmer Barge Line site (hereafter referred to as the Palmer site) is the location of a facility that serviced and

maintained barges and other vessels. The facility is currently inactive (Ref. 5, p. 4). The facility is located

approximately 4.5 miles east - northeast of the City of Port Arthur in Jefferson County, Texas (Ref.3, pp. 1-2). The

facility encompasses approximately 17 acres and is located on Old Yacht Club Road on the Southeast Industrial

Islet. The facility is bounded to the north by vacant property and the Industrial Property Tax Company, to the east

by Sabine Lake, to the south by the State Marine Superfund site, and to the west by Old Yacht Club Road (Ref. 5,

p. 4; Ref. 9, p. 5, Ref. 27, p. 8). The site is situated approximately 0.5 mile southwest of the point where the Neches

River enters the Sabine-Neches Canal (Ref. 3, p. 1). A Site Location Map and Site Area Map are provided as

Figures A-l and A-2 of Attachment A, respectively.

In April of 1982, John H Palmer, President of the Palmer Barge Line, Inc., purchased approximately 17 acres from

the City of Pon Arthur. In July 1983, Banker Phares (a trustee of Jefferson County) placed a lien on the Palmer

Barge Line, Inc. property. In October 1994, Wrangler Capital assumed all claims from the bankruptcy proceedings

for the Palmer Barge Line, Inc. site. In July 1997, Wrangler Capital purchased the property from receivership and

the company ceased operations as a barge and marine vessel service and maintenance company (Ref. 5, p. 4).

Sometime in 1997, the northern portion of the property was leased to a tenant who currently performs marine

salvage operations. The central portion of the property was leased to the Scurloc-Permian Company for vehicle

parking only (Ref. 5, p. 5). In a letter dated 16 October 1999, Mr. Chester Slay, believed to be the current owner

of the site, stated that he purchased the shipyard property adjacent to the State Marine Superfund Site (i.e., the

Palmer Barge Line Site) (Ref. 35, p. 3).

OPERATIONAL HISTORY

The Palmer site began operations sometime in 1982 and continued until the middle of 1997 (Ref. 5, p. 1). Primary

operations conducted at the Palmer site included cleaning, degassing, and maintenance and inspection of barges and

other marine equipment. Typical cleaning operations, also referred to as stripping, included the removal of sludge,

liquid (heels), and all other residual constituents. This cleaning was accomplished by pressure steaming the vessel

holds, engines, and boilers. Degassing activities involved the removal of explosive vapors from the barge hold using

nitrogen or boiler exhaust. Maintenance and inspection activities included the replacement and/or repair of valves,

engines, and line leaks followed by pressure tests and fracture assessments (Ref. 5, pp. 4-5; Ref. 9, p. 6).

Reportedly, Palmer Barge Line, Inc. utilized two diesel/mixed fuel boilers to produce low-pressure steam to aid in

the cleaning of barges. Engines were degreased and residuals spilled during the loading and unloading of the barges

were stored on site in slop tanks (Ref. 5, p. 5; Ref. 7, p. 2; Ref. 9, p. 6).

Structures at the site include various-sized steel above ground storage tanks (ASTs), several open-top slop tanks,

roll-off boxes, and 55-gallon drums (Ref. 5, p. 8; Ref. 9, p. 6). Free standing oily liquids and stained soils have also

been observed at the site (Ref. 5, Health and Safety Plan, p. 4). A detailed description of each of the above

structures, as well as additional structures not previously mentioned, is presented in the following paragraphs. A Site

Plan is provided as Figure A-3 of Attachment A.

Four ASTs (identified as Wastewater ASTs on Figure A-3) are located in the northeastern portion of the site. The

four ASTs, one estimated at 25,000 gallon capacity and three 5,000 gallon capacity tanks, are constructed of steel

and surrounded by an earthen berm measuring approximately 90 feet by 50 feet by 3 feet high (Ref. 9, p. 7). The

MRS Documentation Record Palmer Barge Line Site

05/03/00 7 TXD068104561

00061 1
25,000 gallon capacity AST is identified as Tank 102 on Figure A-3 of Attachment A. These four ASTs were used

for bulk waste storage during barge cleaning operations at the site. The four ASTs are rusting near the base and

are believed to be full of unknown liquids. One foot of oily liquid was observed inside the berm during a site visit

conducted in 1998; however, no free-standing liquids or stained soils were observed inside the berm during the most

recent field activities conducted in October 1999 (Ref. 9, p. 7).

Four ASTs are located adjacent to the boiler house in the southwestern portion of the property (Ref. 5, pp. 5, 8).

The estimated capacity of each of these ASTs is 7,000 gallons and the ASTs are reportedly full of liquid. Three of

the four ASTs reportedly were used to store liquids as a fuel source for two boilers to produce steam during site

operations (Ref. 5, p. 5; Ref. 9, pp. 7-8). The fourth AST was reportedly used for freshwater storage. It is believed

that diesel and other petroleum-type products were stored in the ASTs (Ref. 6, p. 8; Ref. 9, p. 8). The ASTs are

located directly on the ground and no containment features are associated with these ASTs. Numerous pipes and

valves were observed to connect the ASTs, some of which were reported to have leaked to the surrounding soil

(Ref. 9, p. 8).

Four open-top slop tanks and five closed slop tanks are located on site. The open-top slop tanks are located west

of the flare and consist of steel containers full of an oily material. These slop tanks each measure approximately

8 feet by 5 feet by 4 feet (or 6 cubic yards) (Ref. 9, p. 8). The soil around the slop tanks is stained and stressed

vegetation has been noted. The open-top slop tanks are situated directly on the ground with no secondary

containment present (Ref. 9, p. 8). Three slop tanks are located in the northern portion of the property and the

remaining two tanks are located in the eastern portion of the property (Ref. 9, p. 8).

Three horizontal ASTs are located near the southeast comer of the site. The estimated capacity of the three tanks

is 10,000 gallons each (Ref. 9, p. 7). A concrete berm, measuring approximately 30 feet by 30 feet by 1 foot high,

surrounds the three ASTs and contained an unknown greenish-colored liquid during the most recent field activities

conducted in October 1999 (Ref. 6, pp. 4-5; Ref. 9, p. 7). The tanks are believed to be full of liquid and were

probably used as part of the barge cleaning and degassing system (Ref. 9, p. 7). Stained soils are present around

the berm and appear to be the result of tank overflow (Ref. 9, p. 7).

Twelve ASTs are located in the eastern portion of the site. All of the ASTs are identical in size (estimated capacity

is 7,000 gallons each) and shape and are surrounded by a concrete berm measuring approximately 95 feet by 30 feet

by 1 foot high (Ref. 5, p. 5; Ref. 6, p. 5; Ref. 9, p. 7). An oily liquid was observed inside the berm in October 1999,

although the tanks do not appear to be leaking (Ref. 5, p. 5; Ref. 6, p. 5; Ref. 9, p. 7). There are numerous pipes

and valves connecting the tanks which most likely aided in the liquid transfer and separation activities (Ref. 9, p. 7).

The tanks appeared to be in good physical condition as no rusting or leaking was observed during the October 1999

field activities. However, stained soil was observed around the concrete berm and appears to be the result of tank

overflow (Ref. 5, p. 10; Ref. 9, p. 7).

A flare, located generally in the central portion of the site, was used to burn excess gasses and liquids produced

during site operations (Ref. 9, p. 8). Areas of concern include stained soils immediately below and around the flare

stack (Ref. 5, p. 10).

One roll-off box is located east of the 12-tank AST battery. The roll-off box contained a dark, oily sludge (Ref. 5,

p. 5). An abandoned vacuum truck was noted near the bulkhead in the eastern portion of the site. The contents

of the vacuum truck are unknown (Ref. 6, p. 5). An oil/water separator, consisting of two ASTs, is located directly

southwest of the 12-tank AST battery. The oil/water separator appears to be in good condition (Ref. 9, p. 9).

MRS Documenlation Record Palmer Barge Line Site

05/03/00 8 TXD068104561

0 0 0 6 1 2
Additional areas of concern include miscellaneous 55-gallon drums, compressed gas cylinders, paint cans and

buckets, all of whose contents are unknown (Ref. 9, pp. 8-9). Two rectangular-shaped ASTs, each approximately

150 gallons, are located within the vicinity of the 12-tank AST battery. These ASTs most likely served as fuel tanks

and contained diesel, which was used for site vehicle refueling (Ref. 6, pp. 5-6; Ref. 9, p. 9).

REGULATORY HISTORY

In December 1996, the Texas Natural Resources Conservation Commission (TNRCC) Region 10 field office

conducted a multi-media investigation of the Palmer site. The primary purpose of the investigation was to determine

the facility's air compliance status with the Federal Clean Air Act (FCAA) (Ref. 7, p. 1; Ref. 9, p. 9). The Palmer

site operated under two permit exemptions: permit exemption X-3226 and X-3346 (Ref. 7, p. 1). According to permit

exemption X-3226, issued on 7 January 1982, the following products were stored within the 12-tank AST battery:

fuel oil, gasoline, naphtha, and toluene. However, the actual contents of the tanks have not been verified (Ref. 7,

pp. 2-3). At the time of the preparation of this documentation record, additional sampling of the various on-site tanks

had been performed, but the analytical results are still pending.

As listed in permit exemption X-3346, compounds expected to be encountered during barge cleaning operations

include: alcohols, crude oil, diesel, gasoline, kerosene, jet fuel, mineral oils, naphtha, marine diesel, toluene, and lube

oil (Ref. 7, p. 28). Records reviewed by TNRCC personnel revealed that vessels with numerous other compounds

not represented in the permits have been encountered at this facility, including: ammonia, cyclohexane, adiponitrile,

propylene, butadiene, and hexane (Ref. 7, pp. 28-30).

In March 1998, the TNRCC Region 10 field office, in cooperation with the U.S. Environmental Protection Agency

(USEPA) Region 6, prepared a Preliminary Assessment (PA)/Screening Site Inspection (SSI) for the Palmer site.

Five waste source areas were identified by the TNRCC during this particular investigation which are believed to

be the result of historical site operations (Ref. 9, pp. 9-10). A total of thirteen soil and twelve sediment samples

were collected and analyzed as part of this investigation (Ref. 5, pp. 24-25). Analytical results for these samples

indicated that several metals were detected in both surface soil and sediment samples collected from various areas

of the site and in the adjacent Sabine Lake (Ref. 9, p. 10). This report has been included as Reference 5.

In My 1999, a contractor under the direction of the TNRCC Region 10 sampled a majority of the ASTs, roll-off

boxes, and slop tanks located at the site for characterization purposes. The samples collected were analyzed for

Total Characteristic Leaching Procedure (TCLP) characteristics only for volatiles, semivolatiles, pesticides/PCBs,

and metals (Ref. 9, p. 10). The TCLP analysis identifies the potential for a substance to leach from the sampled

material. Analytical results from these samples indicated several compounds that exceeded the practical

quantitation tout (PQL) used by the laboratory for comparison purposes. These compounds included: barium, lead,

2-methylphenol, 3 & 4-methylphenols, and benzene. Locations of sample stations for the TNRCC investigation are

included on Figure A-4 of Attachment A The entire report produced by the contractor, including analytical results

for samples collected during this investigation, has been provided as Reference 8.

In October 1999, a contractor under direction of the USEPA Region 6, performed an Expanded Site Inspection

(ESI) at the Palmer site in an effort to determine the presence and nature of contamination in known or suspected

on-site and off-site locations. Additionally, migration routes and routes of exposure of site-related constituents were

determined for the site (Ref. 9, p. 2). The ESI field activities focused on the collection of soil, ground water, and

sediment samples (Ref. 9, p. 3). Samples collected during the ESI from Sources 1 through 6 were analyzed for all

target compound list (TCL) and target analyte list (TAL) substances per the USEPA Contract Laboratory Program

(CLP) statement of work.

Laboratory analytical results for samples collected during the ESI confirmed the presence of site-related

contaminated soil and, to a lesser extent, contaminated ground water, in several source areas at the site. Site-related

contaminants of concern include metals (Ref. 9, pp. 31-39). Further, laboratory analytical results for sediment

samples obtained from Sabine Lake confirmed that site-attributable contamination was present in Sabine Lake (Ref.

9, p. 80). Sabine Lake is considered a fishery and used for contact and recreational uses (Ref. 29, p. 1). This entire

report has been provided as Reference 9.

SOURCE DESCRIPTION

Ten sources have been identified at the Palmer site. A detailed description of each source is presented in this

section. A complete discussion, including source identification, hazardous substances present and available to a

pathway, likelihood of release, and waste characteristics are presented for each source sequentially for the reader.

Background Soil Samples

In an effort to evaluate background soil conditions at the Palmer Site, background soil samples were collected during

the 1999 ESI from an on site area not suspected to be impacted by site operations. A total of two shallow soil

borings were completed in the northwestern portion of the site at Stations 032 and 033. From each shallow soil

boring, one surface soil sample was collected from a depth of 0 to 2 feet below ground surface (bgs) and a second

sample was collected from a depth of 2 to 4 feet bgs (Ref. 9, p. 31). The background soil sample locations are

depicted on Figure A-5 of Attachment A.

Background soil samples collected during the 1999 ESI were analyzed for all target compound list (TCL) and target

analyte list (TAL) substances per the USEPA Contract Laboratory Program (CLP) statement of work. The

USEPA Region 6 ESAT performed data validation for the ESI data packages prepared by the designated CLP

laboratories. The validators reviewed the data packages to verify that they met the USEPA technical requirements

and quality assurance (QA) guidelines established for the CLP (Ref. 17, pp. 3-11, 21, 22). Maximum concentrations

for each analyte for each depth interval have been presented in the following table.

SOURCE CHARACTERIZATION

Information pertaining to Source 1, contaminated soils associated with the four wastewater above ground storage

tanks (ASTs), is provided in the following paragraphs.

2.2.1 Source Identification

Number of the source: 1

Name and description of the source: Contaminated soils at the wastewater ASTs

Soil contamination has been identified in the area of the four wastewater ASTs located in the northeastern portion

of the site. This source will be classified and evaluated as the HRS source type "contaminated soils." The

contaminated soil is believed to be the result of releases of hazardous substances from the four ASTs or other

chemical handling at the site. The ASTs were used for bulk materials storage during barge cleaning operations and

Source 1: Contaminated Soils-Waste water ASTs

SD - Hazardous Substances Associated with a Source

are believed to be full of unknown liquids (Ref. 5, p. 8; Ref. 9, p. 7). The bases of the tanks are rusted and 1 foot

of oily liquid was observed inside the berm during a site visit conducted in 1998, although no free-standing liquid or

stained soil were noted hi this area during field activities conducted hi October 1999 (Ref. 9, p. 7).

Location of the source with reference to a map of the site:

Contaminated soil is located in the area of the four wastewater ASTs in the northeastern portion of the Pakner site,

immediately north of the gravel parking area as depicted on Figure A-5 of Attachment A (the 25,000 gallon tank in

this area is identified as Tank 102). The area of this source is defined by the locations of samples 001, 002, 003, 004,

005, and 006 (Ref. 11, pp. 1-9, 13, 25; Ref. 12, pp. 1-8, 9, 14-15, 24; Ref. 13, pp. 2-3), which are shown on Figure

A-5 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored; therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored; therefore, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored; therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: Portions of this contaminated soil source are located within

an earthen berm (Ref. 9, p. 7) that surrounds the wastewater ASTs, but the contaminated soil also extends outside

the area encompassed by this containment structure. Considering that the analytical results obtained from soil

samples collected during the 1999 ESI revealed the presence of metals at elevated concentrations outside of the berm

(Ref. 11, pp. 13, 25; Ref. 12, pp. 14-18) and that no containment structures are present to limit the migration of

hazardous substances already outside the berm, a containment factor value of 10 will be assigned to this source (Ref.

1, Table 4-2).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the United States Environmental Protection Agency (USEPA) Region 6. A total

of seven shallow soil borings (stations 001 through 007) were completed around the four wastewater ASTs (Ref.

9, p. 32). From each soil boring, one surface soil sample was collected from a depth of 0 to 2 feet below ground

surface (bgs) and a second sample was collected from a depth of 2 to 4 feet bgs (Ref. 6, pp. 10-13; 9, p. 32).

The analytical results presented in Table 1 are evidence of the contamination associated with Source 1, contaminated

soils associated with the wastewater ASTs. Source sample locations are presented on Figure A-5 of Attachment

A

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of antimony, barium,

cadmium, copper, iron, lead, and zinc (Ref. 11, pp. 13, 25; Ref. 12, pp. 14-18). Sample quantitation limits (SQLs)

were calculated for each hazardous substance and sample. The SQLs were used for comparison purposes in order

2.2.3 Identify Hazardous Substances Available to a Pathway

Because containment for Source 1 is greater than 0, the following substances associated with Source 1 are available

to the surface water pathway:

Antimony

Cadmium

Iron

Barium

Chromium

Lead

Copper

Zinc

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake (Ref. 9, p. 78). Sabine Lake

is located approximately 80 feet east of the location of the four wastewater ASTs, as illustrated on Figure A-3 of

Attachment A.

2.3 LIKELIHOOD OF RELEASE

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 1 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

The hazardous substances associated with Source 1 are presented in Table 1. For the surface water migration

pathway (and threats), the selection of the substance that potentially poses the greatest hazard is based on the toxicity

factor value combined with its mobility, persistence, and/or bioaccumulation potential factor values (Ref. 1, Sec.

2.4.1). The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in

evaluating the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The substance associated

with Source 1 potentially posing the greatest hazard is lead. See sections 4.1.3.2 and 4.1.4.2 of this document.

Many of the same substances have been identified in each of the ten sources being evaluated for the Palmer site.

••Rather than reproducing a similar table for each source, a comprehensive list of substances found in Sources 1

through 10 has been produced here in order to evaluate the substance that potentially poses the greatest hazard.

2.4.2.1.1 Hazardous Constituent Quantity (Tier A) - Not Calculated

The hazardous constituent quantity is not available; therefore, it is not possible to adequately determine a hazardous

constituent quantity (Tier A) for Source 1 (Ref. 1, Sec. 2.4.2.1.1). As a result, the evaluation of hazardous waste

quantity proceeds to the evaluation of Tier B, hazardous waste stream quantity (Ref. 1, Sec. 2.4.2.1.2).

2.4.2.1.2 Hazardous Wastestreani Quantity (Tier B) - Not Calculated

The hazardous wastestream quantity is not available; therefore, it is not possible to adequately determine a hazardous

wastestream quantity (Tier B) for Source 1 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous waste

stream quantity proceeds to the evaluation of Tier C, volume (Ref. 1, Sec. 2.4.2.1.3).

2.4.2.1.3 Volume (Tier C) - Not Calculated

The volume of contaminated soils associated with Source 1 is not available; therefore, it is not possible to adequately

determine a volume (Tier C) for Source 1 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous waste

stream quantity proceeds to the evaluation of Tier D, area (Ref. 1, Sec. 2.4.2.1.4).

2.4.2.1.4 Area (Tier D)

The area of contaminated soils associated with Source 1 will be evaluated by estimating the surface area delineated

by the soil sample locations with analytical results indicating observed contamination. The area of soil contamination

will be defined as the total area lying between samples 001, 002, 003, 004, 005, and 006, as shown on Figure A-5

of Attachment A (Ref. 14, p. 10). The source area was measured by connecting the soil sample locations having

analytical results indicating the presence of hazardous substances exceeding the sample quantitation limits (SQLs).

This polygonal area was traced from a scaled site map and measured using AutoCAD Release Version 14.0 (Ref.

15, pp. 1-3) to determine the source area. According to the HRS Rule, a value from Table 2-5 is assigned for the

source type "contaminated soils" based on the area of the source, as measured in square feet, and divided by a factor

of 34,000 (Ref. 1, Sec. 2.4.2.1.4, Table 2-5). The calculated approximate surface area of the Source 1 contaminated

soil equals 5,592 square feet.

Area of Source 1: 5,592 square feet

Value Assigned Area (from HRS Table 2-5): 0.16

Source 2: Contaminated Soils - Boiler House ASTs

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 2, contaminated soils associated with the boiler house ASTs, is presented in the

following paragraphs.

2.2.1 Source Identification

Number of the source: 2

Name and description of the source: Contaminated soil in the boiler house AST area.

Soil contamination has been identified in the area of the boiler house ASTs located hi the southwestern portion of the

site. This source will be classified and evaluated as the HRS source type "contaminated soils." The contaminated

soil is believed to be the result of releases of hazardous substances from the four ASTs or other chemical handling

at the site. Three of the four ASTs were used to store liquids as a fuel source for two boilers to produce steam

during site operations. The fourth AST was reportedly used for fresh water storage. Numerous pipes and valves

were observed to connect the ASTs, some of which were reported to have leaked to the surrounding soil (Ref. 9,

p. 8). It is believed that diesel and other petroleum-type products were stored in the ASTs (Ref. 5, pp. 5, 8; Ref. 6,

p. 8).

Location of the source with reference to a map of the site:

This contaminated soil source is located in the area of the boiler house ASTs in the southwestern portion of the

Palmer site, near the southern property boundary as depicted on Figure A-5 of Attachment A. The area of this

source is defined by the locations of samples 008, 009, 010, Oil, 012, and 013 (Ref. 13, pp. 4-6; Ref. 17, pp. 1-10,

12-17, 21), which are shown on Figure A-5 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored; therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored; therefore, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored; therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: The laboratory analytical results from surface and subsurface

soil sampling conducted during the 1999 ESI revealed the presence of metals in the soils surrounding the boiler house

ASTs (Ref. 17, pp. 1-8, 12-17). There are no containment features to limit the migration of hazardous substances

associated with the contaminated soil source. Therefore, this source will be assigned a containment factor value of

10 (Ref. 1, Table 4-2).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the USEPA Region 6. The analytical results presented in Table 3 are evidence

of the contamination associated with Source 2. Six shallow soil borings (stations 008 through 013) were advanced

around the boiler house ASTs. A total of six surface soil samples (one from each station) were collected from a

depth of 0 to 2 feet bgs. Two subsurface soil samples were collected from a depth of 2 to 4 feet bgs; one each from

stations 012 and 013 (Ref. 9, p. 34). Soil sample locations associated with Source 2 are presented on Figure A-5

of Attachment A.

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of aluminum, antimony,

arsenic, barium, cadmium, chromium, cobalt, copper, iron, lead, magnesium, mercury, nickel, and zinc (Ref. 17, pp.

1-8). SQLs were calculated for each hazardous substance and sample. The SQLs were used for comparison

purposes in order to establish the presence of CERCLA-eligible hazardous substances. SQL calculations are

included as Reference 13. QA/QC summary forms, result summaries, and chain of custody forms for samples

associated with Source 3 are included as References and 17.

Because containment for Source 2 is greater than 0, the following substances associated with Source 2 are available

to the surface water pathway:

Aluminum Antimony Arsenic

Barium Cadmium Chromium

Cobalt Copper Iron

Lead Magnesium Mercury

Nickel Zinc

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake (Ref. 9, p.78). Sabine Lake

is located approximately 320 feet east of the four boiler house ASTs, as illustrated on Figure A-3 of Attachment A

2.3 LIKELIHOOD OF RELEASE

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 2 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

Presented in Table 3 are the hazardous substances associated with Source 2. Many of the same substances have

been identified in each of the ten sources being evaluated for the Palmer site. Rather than reproducing a similar table

for each source, a comprehensive list has been produced in Table 2 (refer to page 19 of this documentation record).

The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in evaluating

the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The substance associated with

Source 2 potentially posing the greatest hazard is mercury. See sections 4.1.3.2 and 4.1.4.2 of this document.

2.4.2.1.1 Hazardous Constituent Quantity (Tier A) - Not Calculated

The hazardous constituent quantity is not available; therefore, it is not possible to adequately determine a hazardous

constituent quantity (Tier A) for Source 2 (Ref. 1, Sec. 2.4.2.1.1). As a result, the evaluation of hazardous waste

quantity proceeds to the evaluation of Tier B, hazardous wastestream quantity (Ref. 1, Sec. 2.4.2.1.2).

The hazardous wastestream quantity is not available; therefore, it is not possible to adequately determine a hazardous

wastestream quantity (Tier B) for Source 2 (Ref._ 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier C, volume (Ref. 1, Sec. 2.4.2.1.3).

2.4.2.1.3 Volume (Tier C) - Not Calculated

The volume of contaminated soils associated with Source 2 is not available; therefore, it is not possible to adequately

determine a volume (Tier C) for Source 2 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier D, area (Ref. 1, Sec. 2.4.2.1.4).

2.4.2.1.4 Area (Tier D)

The area of contaminated soils associated with Source 2 will be evaluated by estimating the surface area delineated

by the soil sample locations with analytical results indicating observed contamination. The area of soil contamination

will be defined as the total area lying between these samples locations, which include samples 008, 009, 010, Oil, 012,

and 013 shown on Figure A-5 of Attachment A (Ref. 14, p. 10).

The source area was measured by connecting the soil sample locations having analytical results indicating the

presence of hazardous substances exceeding the sample quantitation limits (SQLs). This polygonal area was traced

from a scaled site map and measured using AutoCAD Release Version 14.0 (Ref. 15, pp. 1-3) to determine the

source area. According to the HRS Rule, a value from Table 2-5 is assigned for the source type "contaminated soils"

based on the area of the source, as measured in square feet, and divided by a factor of 34,000 (Ref. 1, Sec. 2.4.2.1.4,

Table 2-5). The calculated approximate surface area of the contaminated soil at Source 2 equals 596 square feet.

Area of Source 2: 596 square feet

2.4.2.1.5 Source Hazardous Waste Quantity Value

According to the HRS Rule, the highest of the values assigned to each source for hazardous constituent quantity (Tier

A), hazardous wastestream quantity (Tier B), volume (Tier C), and area (Tier D) should be assigned as the source

hazardous waste quantity value. As .such, area (Tier D) was the only tier evaluated for Source 2. Therefore, the

area will be assigned as the source hazardous waste quantity value for Source 2 (Ref. 1, Sec. 2.4.2.1.5).

result of releases of hazardous substances from the slop tanks or other chemical handling at the site. The four opentop slop tanks consist of steel containers full of an oily material. The soil below the slop tanks is stained and stressed

vegetation has been observed in this area (Ref. 9, p. 8).

Location of the source with reference to a map of the site:

This contaminated soil source is located in the area of the four open-top slop tanks are located in the western portion

of the site, approximately 150 feet east of Old Yacht Club Road, as depicted on Figure A-5 of Attachment A The

area of this source is defined by the location of samples 014, 015, 016, and 017 (Ref. 11, pp. 1-9, 14-17, 25; Ref. 13,

pp. 7-9), which are shown on Figure A-5 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: The laboratory analytical results obtained from surface soil

sampling conducted during the 1999 ESI indicated the presence of several metals in the soil surrounding the open-top

slop tanks (Ref. 11, pp. 14-17, 25). The four steel slop tanks are open at the top, filled with an oily material, and

have no secondary containment devices. Stained soil and stressed vegetation were observed in this area during the

1999 ESI (Ref. 9, p. 8). Since there are no containment features present to limit the migration of hazardous

substances from the contaminated soil source, a containment factor value of 10 will be assigned for this source (Ref.

1, Table 4-2).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the USEPA Region 6. The analytical results presented in Table 4 are evidence

of the contamination associated with Source 3. Four shallow soil borings (stations 014 through 017) were advanced

around the open-top slop tanks. One surface soil sample was collected from each boring station at a depth of 0 to

2 feet bgs (Ref. 9, pp. 35). Soil sample locations associated with Source 3 are presented on Figure A-5 of

Attachment A.

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of cobalt, lead, nickel, and

zinc. The USEPA Region 6 ESAT performed data validation for the ESI data packages prepared by the designated

CLP laboratories (Ref. 11, pp. 1-9). SQLs were calculated for each hazardous substance and sample. The SQLs

were used for comparison purposes in order to establish the presence of CERCLA-eligible hazardous substances.

SQL calculations are included as Reference 13. QA/QC summary forms, result summaries* and chain of custody

forms for samples associated with Source 3 are included as References 11.

SD - Waste Characteristics

2.2.3 Identify Hazardous Substances Available to a Pathway

Because containment for Source 3 is greater than 0, the following substances associated with Source 3 are available

to the surface water pathway: cobalt, lead, nickel, and zinc.

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake (Ref. 9, p. 78). Sabine Lake

is located approximately 400 feet east of the location of the four open-top slop tanks as illustrated on Figure A-3 of

Attachment A.

2.3 LIKELIHOOD OF RELEASE

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 3 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

Presented in Table 4 are the hazardous substances associated with Source 3. Many of the same substances have

been identified in each of the ten sources being evaluated for the Palmer site. Rather than reproducing a similar table

for each source, a comprehensive list has been produced in Table 2 (refer to page 19 of this documentation record).

The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in evaluating

the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The substance associated with

Source 3 potentially posing the greatest hazard is lead. See sections 4.1.3.2 and 4.1.4.2 of this document.

2.4.2 Hazardous Waste Quantity

2.4.2.1 Source Hazardous Waste Quantity

2.4.2.1.1 Hazardous Constituent Quantity (Tier A) - Not Calculated

The hazardous constituent quantity is not available; therefore, it is not possible to adequately determine a hazardous

constituent quantity (Tier A) for Source 3 (Ref. 1, Sec. 2.4.2.1.1). As a result, the evaluation of hazardous waste

quantity proceeds to the evaluation of Tier B, hazardous wastestream quantity (Ref. 1, Sec. 2.4.2.1.2).

2.4.2.1.2 Hazardous Wastestream Quantity (Tier B) - Not Calculated

The hazardous wastestream quantity is not available; therefore, it is not possible to adequately determine a hazardous

wastestream quantity (Tier B) for Source 3 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier C, volume (Ref. 1, Sec. 2.4.2.1.3).

2.4.2.1.3 Volume (Tier C) - Not Calculated

The volume of contaminated soils associated with Source 3 is not available; therefore, it is not possible to adequately

determine a volume (Tier C) for Source 3 (Ref^l, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier D, area (Ref. 1, Sec. 2.4.2.1.4).

2.4.2.1.4 Area (Tier D)

The area of contaminated soils associated with Source 3 will be evaluated by estimating the surface area delineated

by the soil sample locations with analytical results indicating observed contamination. The area of soil contamination

will be defined as the total area lying between these samples locations, which include samples 014, 015, 016, and 017,

as shown on Figure A-5 of Attachment A (Ref. 14, p. 10). The source area was measured by connecting the soil

sample locations having analytical results indicating the presence of hazardous substances exceeding the sample

quantitation limits (SQLs). This polygonal area was traced from a scaled site map and measured using AutoCAD

Release Version 14.0 (Ref. 15, pp. 1-3) to determine the source area. According to the HRS Rule, a value from

Table 2-5 is assigned for the source type "contaminated soils" based on the area of the source, as measured in square

feet, and divided by a factor of 34,000 (Ref. 1, Sec. 2.4.2.1.4, Table 2-5). The calculated approximate surface area

of the contaminated soil associated with Source 3 equals 269 square feet.

Area of Source 3: 269 square feet

Value Assigned Area (from HRS Table 2-5): 0.008

2.4.2.1.5 Source Hazardous Waste Quantity Value

According to the HRS Rule, the highest of the values assigned to each source for hazardous constituent quantity (Tier

A), hazardous wastestream quantity (Tier B), volume (Tier C), and area (Tier D) should be assigned as the source

hazardous waste quantity value. As such, area (Tier D) was the only tier evaluated for Source 3. Therefore, the

area will be assigned as the source hazardous waste quantity value for Source 3 (Ref. 1, Sec. 2.4.2.1.5).

Source 4: Contaminated Soils - Horizontal ASTs

SD - Characterization and Containment

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 4, contaminated soils associated with the horizontal ASTs, is presented in the

following paragraphs.

2.2.1 Source Identification

Number of the source: 4

Name and description of the source: Contaminated soil located in the horizontal AST area

Soil contamination has been identified in the area of the three horizontal ASTs located immediately south of the 12-

tank AST battery. This source will be classified and evaluated as the HRS source type "contaminated soils." The

contaminated soil is believed to be the result of releases of hazardous substances from the horizontal tanks or other

chemical handling at the site. These tanks are believed to be full of liquid and were probably used as part of the

barge cleaning and degassing system (Ref. 9, p. 7). A concrete berm, measuring approximately 30 feet by 30 feet

by 1 foot high, surrounds the three ASTs and contained an unknown greenish-colored liquid in October 1999 (Ref.

6, pp. 4-5; Ref. 9, p. 7).

Location of the source with reference to a map of the site:

This contaminated soil source is located in the area of the three horizontal ASTs are located generally in the southeast

comer of the site, approximately 80 feet west of Sabine Lake, as depicted on Figure A-5 of Attachment A The area

of this source is defined by the locations of samples 018, 019, 020, and 021 (Ref. 11, pp. 1-10, 18-21, 25-26; Ref. 13,

pp. 9-10), which are shown on Figure A-5 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particuiate release to air: The air migration pathway was not scored, therefore, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: Portions of this contaminated soil source are located within a

concrete berni (Ref. 9, p. 7) that surrounds the three horizontal ASTs, but the contaminated soil also extends outside

the area encompassed by this containment structure. The analytical results of surface and subsurface soil sampling

conducted during the 1999 ESI indicate the presence of several metals in the soils located outside of the berm (Ref.

11, pp. 18-21). There are no containment features to limit the migration of hazardous substances associated with the

contaminated soil source outside of the berm. Therefore, this source will be assigned a containment factor value of

10 (Ref. 1, Table 4-2).

Source 4: Contaminated Soils - Horizontal ASTs

SD - Characterization and Containment

A concrete benn, measuring approximately 30 feet by 30 feet by 1 foot high surrounds the three horizontal ASTs.

As noted by the TNRCC during the 1999 PA/SSI, the berm showed signs of breaching and a dark, oily sludge was

observed around the ASTs (Ref. 6, pp. 4-5; Ref. 9, p. 7). Further, an unknown greenish-colored liquid was noted

inside the berm and stained soils were noted immediately outside of the berm during the 1999 ESI (Ref. 9, p. 7).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the USEPA Region 6. The analytical results presented in Table 5 are evidence

of the contamination associated with Source 4. Four shallow soil borings (stations 018 through 021) were advanced

around the three horizontal ASTs. From each soil boring, one surface soil sample was collected from a depth of 0

to 2 feet bgs (Ref. 9, p. 35). Soil sample locations associated with Source 4 are presented on Figure A-5 of

Attachment A.

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of chromium, cyanide, lead,

mercury, and zinc (Ref. 11, pp. 1-10). SQLs were calculated for each hazardous substance and sample. The SQLs

were used for comparison purposes in order to establish the presence of CERCLA-eligible hazardous substances.

SQL calculations are included as Reference 13. QA/QC summary forms, result summaries, and chain of custody

forms for samples associated with Source 4 are included as References 11.

Because containment for Source 4 is greater than 0, the following substances associated with Source 4 are available

to the surface water pathway: chromium, cyanide, lead, mercury, and zinc.

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake (Ref. 9, p. 78). Sabine Lake

is located approximately 80 feet east of the location of the three horizontal ASTs, as illustrated on Figure A-3 of

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 4 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

Presented in Table 5 are the hazardous substances associated with Source 4. Many of the same substances have

been identified in each of the ten sources being evaluated for the Palmer site. Rather than reproducing a similar table

for each source, a comprehensive list has been produced in Table 2 (refer to page 19 of this documentation record).

The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in evaluating

the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The.substance associated with

Source 4 potentially posing the greatest hazard is mercury. See sections 4.1.3.2 and 4.1.4.2 of this document.

The volume of contaminated soils associated with Source 4 is not available; therefore, it is not possible to adequately

determine a volume (Tier C) for Source 4 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier D, area (Ref. 1, Sec. 2.4.2.1.4).

2.4.2.1.4 Area (Tier D)

The area of contaminated soils associated with Source 4 will be evaluated by estimating the surface area delineated

by the soil sample locations with analytical results indicating observed contamination. The area of this source is

defined by the locations of samples 018, 019, 020, and 021 shown on Figure A-5 of Attachment A (Ref. 14, p. 10).

The source area was measured by connecting the soil sample locations having analytical results indicating the

presence of hazardous substances exceeding the sample quantitation limits (SQLs). This polygonal area was traced

from a scaled site map and measured using AutoCAD Release Version 14.0 (Ref. 15, pp. 1-3) to determine the

source area. According to the HRS Rule, a value from Table 2-5 is assigned for the source type "contaminated soils"

based on the area of the source, as measured in square feet, and divided by a factor of 34,000 (Ref. 1, Sec. 2.4.2.1.4,

Table 2-5). The calculated approximate surface area of the contaminated soil associated with Source 4 equals 118

square feet.

Area of Source 4: 118 square feet

2.4.2.1.5 Source Hazardous Waste Quantity Value

According to the HRS Rule, the highest of the values assigned to each source for hazardous constituent quantity (Tier

A), hazardous wastestream quantity (Tier B), volume (Tier C), and area (Tier D) should be assigned as the source

hazardous waste quantity value. As such, area (Tier D) was the only tier evaluated for Source 4. Therefore, the

area will be assigned as the source hazardous waste quantity value for Source 4 (Ref. 1, Sec. 2.4.2.1.5).

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 5, contaminated soils associated with the 12- tank AST battery, is presented in the

following paragraphs.

2.2.1 Source Identification

Number of the source: 5

Name and description of the source: Contaminated soils in the 12-tank AST battery area.

Soil contamination has been identified in the area surrounding the battery of 12 ASTs located in the eastern portion

of the site. This source will be-classified and evaluated as the HRS source type "contaminated soils." The

contaminated soil is believed to be the result of releases of hazardous substances from the ASTs or other activities

at the site. All of the ASTs are identical in.size and shape and are surrounded by a concrete berm measuring

approximately 95 feet by 30 feet by 1 foot high. The tanks appeared to be in good physical condition during the 1999

ESI, but an oily liquid was observed inside the berms (Ref. 5, p. 5; Ref. 6, p. 5; Ref. 9, p. 7) and stained soil,

apparently from an overflow, was observed around the concrete berm (Ref. 5, p. 10; Ref., 9, p. 7). There are

numerous pipes and valves connecting the tanks, which most likely aided in the liquid transfer and separation activities

(Ref. 9, p. 7). According to permit X-3226 exemption, the products stored in the twelve ASTs included fuel oil,

gasoline, naphtha, and toluene. However, the actual tank contents have not been verified (Ref. 7, p. 3).

Location of the source with reference to a map of the site:

This contaminated soil source is located in the area of the 12-tank AST battery are located in the eastern portion of

the site, immediately east of the gravel parking area, as depicted on Figure A-5 of Attachment A. The area of this

source is defined by the locations of samples 022, 023, 024, 025, 026, and 027 (Ref.ll.pp. 1-8, 11, 22-24, 26; Ref.

12, pp. 1-8, 10, 19, 25; Ref. 13, pp. 10-12; Ref. 17, pp. 1-9, 18-20), which are shown on Figure A-5 of Attachment

A

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore, particulate containment was not

evaluated.

Release to ground water: The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: Portions of this contaminated soil source are located within

a concrete berm that surrounds the 12 ASTs, but the contaminated soil also extends outside the area encompassed

by this containment structure. A concrete berm, measuring approximately 30 feet by 30 feet by 1 foot high surrounds

the three horizontal ASTs, but TNRCC noted during the 1999 PA/SSI that the berm showed signs of breaching and

a dark, oily sludge was observed around the ASTs (Ref. 6, pp. 4-5; Ref. 9, p. 7). Further, an unknown greenishcolored liquid was noted inside the berm and stained soils were noted immediately outside of the berm during the 1999

ESI (Ref. 9, p. 7). The analytical results of surface and subsurface soil sampling conducted during the 1999 ESI

revealed the presence of several metals in the soils located outside of the berm (Ref. 11, pp. 11, 22-24; Ref. 12, pp.

10, 19, 25; Ref. 17, pp. 18-20). There are no containment features to limit the migration of hazardous substances

associated with the contaminated soil source outside of the berm. Therefore, this source will be assigned a

containment factor value of 10 (Ref. 1, Table 4-2).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the USEPA Region 6. The analytical results presented in Table 6 are evidence

of the contamination associated with Source 5. Six shallow soil borings (stations 022 through 027) were advanced

outside of the berm on all sides of the 12-tank AST battery. A total of six surface soil samples (one from each

station) were collected from a depth of 0 to 2 feet bgs (Ref. 9, p. 36). Soil sample locations associated with Source

5 are presented on Figure A-5 of Attachment A.

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of aluminum, arsenic,

chromium, cobalt, copper, cyanide, iron, lead, mercury, nickel, and zinc (Ref. 11, pp. 1-8; Ref. 12, pp. 1-8; Ref. 17,

pp. 1-9). SQLs were calculated for each hazardous substance and sample. The SQLs were used for comparison

purposes in order to establish the presence of CERCLA-eligible hazardous substances. SQL calculations are

included as Reference 13. QA/QC summary forms, result summaries, and chain of custody forms for samples

associated with Source 5 are included as References 12, and 17.

2.2.3 Identify Hazardous Substances Available to a Pathway

Because containment for Source 5 is greater than 0, the following substances associated with Source 5 are available

to the surface water pathway:

Aluminum

Cobalt

Iron

Nickel

Arsenic

Copper

Lead

Zinc

Chromium

Cyanide

Mercury

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake. Sabine Lake is located

approximately 80 feet east of the location of the 12-tank AST battery, as illustrated on Figure A-3 of Attachment A

2.3 LIKELIHOOD OF RELEASE

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 5 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

Presented in Table 6 are the hazardous substances associated with Source 5. Many of the same substances have

been identified in each of the ten sources being evaluated for the Palmer site. Rather than reproducing a similar table

for each source, a comprehensive list has been produced in Table 2 (refer to page 19 of this documentation record).

The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in evaluating

the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The substance associated with

Source 5 potentially posing the greatest hazard is mercury. See sections 4.1.3.2 and 4.1.4.2 of this document.

2.4.2 Hazardous Waste Quantity

2.4.2.1 Source Hazardous Waste Quantity

2.4.2.1.1 Hazardous Constituent Quantity (Tier A) - Not Calculated

The hazardous constituent quantity is not available; therefore, it is not possible to adequately determine a hazardous

constituent quantity (Tier A) for Source 5 (Ref. 1, Sec. 2.4.2.1.1). As a result, the evaluation of hazardous waste

quantity proceeds to the evaluation of Tier B, hazardous wastestream quantity (Ref. 1, Sec. 2.4.2.1.2).

2.4.2.1.2 Hazardous Wastestream Quantity (Tier B) - Not Calculated

The hazardous wastestream quantity is not available; therefore, it is not possible to adequately determine a hazardous

wastestream quantity (Tier B) for Source 5 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier C, volume (Ref. 1, Sec. 2.4.2.1.3).

2.4.2.1.3 Volume (Tier C) - Not Calculated

The volume of contaminated soils associated with Source 5 is not available; therefore, it is not possible to adequately

determine a volume (Tier C) for Source 5 (Ref. 1, Sec. 2.4.2.1.3). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier D, area (Ref. 1, Sec. 2.4.2.1.4).

2.4.2.1.4 Area (Tier D)

The area of contaminated soils associated with Source 5 will be evaluated by estimating the surface area delineated

by the soil sample locations with analytical results indicating observed contamination. The area of this source is

defined by the locations of samples 022, 023, 024, 025, 026, and 027, as shown on Figure A-5 of Attachment A (Ref.

14, p. 10). The source area was measured by connecting the soil sample locations having analytical results indicating

the presence of hazardous substances exceeding the sample quantitation limits (SQLs). This polygonal area was

traced from a scaled site map and measured using AutoCAD Release Version 14.0 (Ref. 15, pp. 1-3) to determine

the source area. According to the HRS Rule, a value from Table 2-5 is assigned for the source type "contaminated

soils" based on the area of the source, as measured in square feet, and divided by a factor of 34,000 (Ref. 1, Sec.

2.4.2.1.4, Table 2-5). The calculation of the approximate surface area of the contaminated soils associated with

Source 5 equals 755 square feet.

Area of Source 5: 755 square feet

Value Assigned Area (from HRS Table 2-5): 0.022

2.4.2.1.5 Source Hazardous Waste Quantity Value

According to the HRS Rule, the highest of the values assigned to each source for hazardous constituent quantity (Tier

A), hazardous wastestream quantity (Tier B), volume (Tier C), and area (Tier D) should be assigned as the source

hazardous waste quantity value. As such, area (Tier D) was the only tier evaluated for Source 5. Therefore, the

area will be assigned as the source hazardous waste quantity value for Source 5 (Ref. 1, Sec. 2.4.2.1.5).

Source 6: Contaminated Soils - Flare

SD - Characterization and Containment

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 6, contaminated soils associated with the flare, is presented in the following

paragraphs.

2.2.1 Source Identification

Number of the source: 6

Name and description,of the source: Contaminated soils associated with the flare

Soil contamination has been identified in the. area the flare located in the central portion of the property. This source

will be classified and evaluated as-the HRS source type "contaminated soils." The contaminated soil is believed to

be the result of releases of hazardous substances from chemical handling in this area of the site.

Location of the source with reference to a man of the site:

This contaminated soil source is located in the central portion of the site near the flare and less than 50 feet east of

the open-top slop tanks, as depicted on Figure A-5 of Attachment A. The area of this source is defined by the

locations of samples 028, 029, 030, and 031 (Ref.12, pp. 1-8, 10-11, 20, 26; Ref. 13, p. 12), which are shown on

Figure A-5 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: Areas of stressed vegetation exist around the area immediately

below the flare stack (Ref. 5, p. 10) and the laboratory analytical results from surface and subsurface soil sampling

conducted during the 1999 ESI Recent surface soil sampling conducted indicate presence of several metals in the

soils surrounding the flare (Ref. 12, pp. 20-23). There are no containment features to limit the migration of hazardous

substances associated with the contaminated soil source. Therefore, this source will be assigned a containment factor

value of 10 (Ref. 1, Table 4-2).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed below were detected in soil samples collected during the October 1999 ESI by a

contractor under the direction of the USEPA Region 6: The analytical results presented in Table 7 are evidence of

the contamination associated with Source 6, the flare. A total of four surface soil samples (stations 028 through 031)

were collected from a depth of 0 to 2 feet bgs around the flare (Ref. 9, p. 37). Soil sample locations associated with

Source 6 are presented on Figure A-5 of Attachment A.

Analysis of these samples, conducted through the USEPA CLP, indicated the presence of cadmium, chromium,

copper, iron, lead, mercury, nickel, and zinc (Ref. 12, pp. 1-8). SQLs were calculated for each hazardous substance

and sample. The SQLs were used for comparison purposes in order to establish the presence of CERCLA-eligible

hazardous substances. SQL calculations are included as Reference 13. QA/QC summary forms, result summaries,

and chain of custody forms for samples associated with Source 6 are included as Reference 12.

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 7, wastewater above ground storage tanks (ASTs), is provided in the following

paragraphs.

2.2.1 Source Identification

Number of the source: 7

Name and description of the source: Wastewater ASTs

Four wastewater ASTs are located in the northeastern portion of the site. The four ASTs, one 25,000 gallon capacity

and three 5,000 gallon capacity tanks, are constructed of steel and surrounded by an earthen berm measuring

approximately 90 feet by 50 feet by 3 feet high. These four ASTs were used for bulk storage during barge cleaning

operations at the site (Ref. 5, p. 8; Ref. 9, p. 7). This source will be classified as the HRS source type "above ground

tank." The four wastewater ASTs will be aggregated and evaluated as one source because they affect the same

targets, have similar waste characteristics and containment features, and lie in the same watershed.

Location of the source with reference to a map of the site:

The four wastewater ASTs are located in the northeastern portion of the Palmer site, immediately north of the gravel

parking area as depicted on Figure A-3 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Participate release to air: The air migration pathway was not scored, therefore, particulate containment was not

evaluated.

Release to ground water The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: The four wastewater ASTs are constructed of steel and

surrounded by an earthen berm measuring approximately 90 feet by 50 feet by 3 feet high (Ref. 9, p. 7). The four

ASTs are rusting near the base. Approximately one foot of oily liquid was observed inside the earthen berm during

a site visit conducted in 1998. Each of the four ASTs is believed to be full of liquid (Ref. 9, p. 7). Analytical results

from liquid samples collected from the wastewater ASTs during the 1999 TNRCC sampling event revealed the

presence of benzene, 2-methylphenol, 3&4-methylphenols, barium and lead (Ref. 8, pp. 99-110, 117-120).

by a contractor under the direction of the TNRCC in July 1999 (Reference 8, pp. 99-119). The samples were

analyzed by a private laboratory using EPA-approved methods for TCLP characteristics only for VOCs, SVOCs,

pesticides, and metals (Ref. 8, pp. 99-110, 117-120). It should be noted that analytical data was not available for the

sample collected from Tank 20; however, based on available information the contents of all of the four tanks were

assumed to be similar. Therefore, Tank 20 will be included in the evaluation of this source. The TCLP identifies the

potential for a substance to leach from the sampled material.

The TCLP analytical data were reviewed for QA/QC issues to verify that the data were usable for HRS scoring

purposes. Practical quantitation limits were established by the laboratory and used for comparison purposes in order

to establish the presence of CERCLA-eligible hazardous substances. QA/QC summary forms, result summaries,

and chain of custody forms for samples associated with Source 7 are included as Reference 8.

Source 8: Boiler House ASTs

SD - Characterization and Containment

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 8, boiler house ASTs, is presented in the following paragraphs.

2.2.1 Source Identification

Number of the source: 8

Name and description of the source: Boiler house ASTs

Four ASTs are located adjacent to the boiler house in the southwestern portion of the propeity (Ref. 5, pp. 5, 8). The

estimated capacity of each of the four ASTs is 7,000 gallons. The ASTs are reportedly full of liquid. Three of the

four ASTs were used to store liquids as a fuel source for two boilers to produce steam during site operations. The

fourth AST was reportedly used for fresh water storage. It is believed that diesel and other petroleum-type products

were and stored in the ASTs (Ref. 5, p. 5; Ref. 6, p. 8; Ref. 9, pp. 7-8). The boiler house ASTs reportedly held a

mixture of wastes from the barge cleaning operations, which were then mixed with naphtha and/or diesel (Ref. 7,

p. 8).

Numerous pipes and valves were observed to connect the ASTs, some of which were reported to have leaked to

the surrounding soil (Ref. 9, p. 8). This source will be classified as the HRS source type "above ground tank." The

four boiler house ASTs will be aggregated and evaluated as one source because they affect the same targets, have

similar waste characteristics and containment features, and lie in the same watershed.

Location of the source with reference to a map of the site:

The boiler house ASTs are located in the southwestern portion of the site, near the southern property boundary as

depicted on Figure A-3 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore, particulate containment was not

evaluated.

Release to ground water. The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: The boiler house ASTs are situated directly on the ground (Ref.

9, pp. 8-9). Each of the four ASTs are believed to be full of liquid. No containment structures, such as a concrete

or earthen berm, are associated with the boiler house ASTs. Numerous pipes and valves connect the ASTs, some

of which were reported by the TNRCC to have leaked (Ref. 9, p. 8).

Analytical results of liquid samples collected from the boiler house ASTs revealed the presence of benzene, 2-

methylphenol, 3&4-methylphenols, and barium (Ref. 8, p. 139-143).

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed in Table 9 were detected in liquid samples collected from the boiler house ASTs

during the TNRCC 1999 sampling event. The analytical results presented in Table 9 are evidence of the

contamination associated with Source 8, boiler house ASTs. Source sample locations are presented on Figure A-4

of Attachment A One liquid sample was collected from each of the four boiler house ASTs (stations 26 through

29) by a contractor under the direction of the TNRCC in July 1999. The samples were analyzed by a private

laboratory using EPA-approved methods for TCLP characteristics only for VOCs, SVOCs, pesticides, and metals

(Ref. 8, pp. 139-143). The TCLP identifies the potential for a substance to leach from the sampled material.

Analytical data were not available for the samples collected from Tanks 27, 28, and 29; however, based on available

information the contents of the tank are assumed to be similar. Therefore, Tanks 27, 28, and 29 will be included in

the evaluation of this source.

The TCLP analytical data were reviewed for QA/QC issues to verify that the data were usable for HRS scoring

purposes. Practical quantitation limits were established by the laboratory and used for comparison purposes in order

to establish the presence of CERCLA-eligible hazardous substances. QA/QC summary forms, result summaries,

and chain of custody forms for samples associated with Source 8 are included as Reference 8.

Source 9: Horizontal ASTs

SD - Characterization and Containment

SOURCE DESCRIPTION

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 9, horizontal ASTs, is presented in the following paragraphs.

2.2.1 Source Identification

Number of the source: 9

Name and description of the source: Horizontal ASTs

Three horizontal ASTs are located immediately south of the 12-tank AST battery. The estimated capacity of each

of the three ASTs is 10,000 gallons. A concrete berm, measuring approximately 30 feet by 30 feet by 1 foot high,

surrounds the three ASTs and contained an unknown greenish-colored liquid in October 1999 (Ref. 6, pp. 4-5; Ref.

9, p. 7). The tanks are believed to be full of liquid and were probably used as part of the barge cleaning and

degassing system (Ref. 9, p. 7). The source associated with the three horizontal ASTs will be classified and

evaluated as the HRS source type "above ground tank." The horizontal ASTs will be aggregated and evaluated as

one source because they affect the same targets, have similar waste characteristics and containment features, and

lie in the same watershed.

Location of the source with reference to a map of the site:

The three horizontal ASTs are located generally in the southeast corner of the site, approximately 80 feet west of

Sabine Lake, as depicted on Figure A-3 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore,, paniculate containment was not

evaluated.

Release to ground water The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: Aconcrete berm, measuring approximately 30 feet by 30 feet

by 1 foot high surrounds the three horizontal ASTs. As noted by the TNRCC during the 1999 PA/SSI, the berm

showed signs of breaching and a dark, oily sludge was observed around the ASTs (Ref. 6, pp. 4-5; Ref. 9, p. 7).

Further, an unknown greenish-colored liquid was noted inside the berm and stained soils were noted immediately

outside of the berm during the 1999 ESI (Ref. 9, p. 7).

Analytical results from liquid samples collected from the horizontal ASTs revealed the presence of benzene, 2-

butanone, 2-methylphenol, 3&4-methylphenols, and barium (Ref. 8, pp. 69-92).

The hazardous substances listed in Table 10 were detected in liquid samples collected from the horizontal ASTs

during the TNRCC 1999 sampling event. The analytical results presented in Table 10 are evidence of the

contamination associated with Source 9, horizontal ASTs. Source sample locations are presented on Figure A-4 of

Attachment A One liquid sample was collected from each of the horizontal ASTs (stations 13 through 16) by a

2.2 SOURCE CHARACTERIZATION

Information pertaining to Source 10, 12- tank AST battery, is presented in the following paragraphs.

2.2.1 Source Identification

Number of the source: 10

Name and description of the source: 12-tank AST battery

Twelve ASTs are located in the eastern portion of the site. All of the ASTs are identical in size and shape and are

surrounded by a concrete berm measuring approximately 95 feet by 30 feet by 1 foot high. Each of the twelve ASTs

has an estimated capacity of 7,000 gallons (Ref. 9, p. 7). An oily liquid was observed inside the berms in October

1999 (Ref. 6, p. 5). There are numerous pipes and valves connecting the tanks which most likely aided in the liquid

transfer and separation activities (Ref. 9, p. 7). The tanks appeared to be in good physical condition, as no rusting

or leaking was observed during the 1999 ESI. However, stained soil was observed around the concrete berm and

appears to be the result of tank overflow (Ref. 5, p. 10; Ref. 9, p. 7).

According to permit X-3226 exemption, the following products were stored in the twelve ASTs: fuel oil, gasoline,

naphtha, and toluene (Ref. 7, p. 3). The source associated with the twelve ASTs will be classified as the MRS

source type "above ground tank." The twelve ASTs will be aggregated and evaluated as one source because they

affect the same targets, have similar waste characteristics and containment features, and lie in the same watershed.

Location of the source with reference to a map of the site:

The 12-tank AST battery is located in the eastern portion of the site, immediately east of the gravel parking area,

as depicted on Figure A-3 of Attachment A.

Containment:

Gas release to air: The air migration pathway was not scored, therefore, gas containment was not evaluated.

Particulate release to air: The air migration pathway was not scored, therefore, particulate containment was not

evaluated.

Release to ground water: The ground water pathway was not scored, therefore, ground water containment was

not evaluated.

Release by overland flow migration and/or flood: The twelve ASTs are constructed of steel. Each of the twelve

ASTs are identical in size and shape and are surrounded by a concrete berm measuring approximately 95 feet by

30 feet by 1 foot high (Ref. 5, p. 5; Ref. 6, pp. 4-5). As noted by the TNRCC during the 1998 PA/SSI, the base of

the tanks were stained with an oily, black material. Additionally, the berm surrounding the twelve ASTs showed

signs of breaching (Ref. 5, p. 5). Analytical results from liquid samples collected from the twelve ASTs revealed

the presence of benzene, 2-methylphenol, 3&4-methylphenols, and barium (Ref. 8, pp. 16-68). Acontainment factor

value of 10 will be assigned based on the evidence of hazardous substance migration from Source 10.

2.2.2 Hazardous Substances Associated with a Source

The hazardous substances listed in Table 11 were detected in liquid samples collected from the twelve ASTs within

the tank battery during the TNRCC 1999 sampling event. The analytical results presented in Table 11 are evidence

of the contamination associated with Source 10, 12-tank ATS battery. Source sample locations are presented on

Figure A-4 of Attachment A One liquid sample was collected from each of the twelve ASTs (stations 1 through

12) by a contractor under the direction of the TNRCC in July 1999 (Ref. 8, pp. 11-12; 16-71). The samples were

analyzed by a private laboratory using EPA-approved methods for TCLP characteristics only for VOCs, SVOCs,

pesticides, and metals (Ref. 8, pp. 16-28, 35-68). The TCLP identifies the potential for a substance to leach from

the sampled material. Analytical data for the sample collected from Tank 7 was not available; however, based on

available information the contents of the twelve ASTs are assumed to be similar. Therefore, Tank 7 will be included

in the evaluation of this source.

The TCLP analytical data were reviewed for QA/QC issues to verify that the data were usable for MRS scoring

purposes. Practical quantitation limits were established by the laboratory and used for comparison purposes in order

to establish the presence of CERCLA-eligible hazardous substances. QA/QC summary forms, result summaries,

and chain of custody forms for samples associated with Source 10 are included as Reference 8.

2.2.3 Identify Hazardous Substances Available to a Pathway

Because containment for Source 10 is greater than 0, the following substances associated with Source 10 are

available to the surface water pathway include: barium, benzene, 2-methylphenol, and 3-&4-methylphenols.

Locally, surface water run-off from the Palmer site discharges directly into Sabine Lake (Ref. 9, p. 78). Sabine Lake

is located approximately 80 feet east of the location of the four wastewater ASTs, as illustrated on Figure A-3 of

Attachment A.

2.3 LIKELIHOOD OF RELEASE

Refer to Section 4.1 of this documentation record for specific information related to samples that meet the criteria

for an observed release to the surface water migration pathway.

2.4 WASTE CHARACTERISTICS

Specific factors related to waste characteristics associated with Source 10 are presented in the subsections below.

2.4.1 Selection of Substance Potentially Posing Greatest Hazard

Presented in Table 11 are the hazardous substances associated with Source 10. Many of the same substances have

been identified in each of the ten sources being evaluated for the Palmer site. Rather than reproducing a similar table

for each source, a comprehensive list has been produced in Table 2 (refer to page 19 of this documentation record).

The substance(s) selected as potentially posing the greatest hazard for the pathway (threat) will be used in evaluating

the waste characteristics category of the pathway (threat) (Ref. 1, Sec. 2.4.1). The substance associated with

Source 9 potentially posing the greatest hazard is benzene. See sections 4.1.3.2 and 4.1.4.2 of this document.

2.4.2 Hazardous Waste Quantity

2.4.2.1 . Source Hazardous Waste Quantity

2.4.2.1.1 Hazardous Constituent Quantity (Tier A) - Not Calculated

The hazardous constituent quantity is not available; therefore, it is not possible to adequately determine a hazardous

constituent quantity (Tier A) for Source 10 (Ref. 1, Sec. 2.4.2.1.1). As a result, the evaluation of hazardous waste

quantity proceeds to the evaluation of Tier B, hazardous wastestream quantity (Ref. 1, Sec. 2.4.2.1.2).

2.4.2.1.2 Hazardous Wastestream Quantity (Tier B) - Not Calculated

The hazardous wastestream quantity is not available; therefore, it is not possible to adequately determine a hazardous

wastestream quantity (Tier B) for Source 10 (Ref. 1, Sec. 2.4.2.1.2). As a result, the evaluation of hazardous

wastestream quantity proceeds to the evaluation of Tier C, volume (Ref. 1, Sec. 2.4.2.1.3).

2.4.2.1.3 Volume (Tier C)

The capacities of the twelve tanks will be assigned as the volume for this source. Each of the tanks' capacities

will be summed and the resulting number will be used to assign a volume based on HRS Table 2-5 for this source.

Each of the 12 tanks has an engineered capacity of 7,000 gallons (Ref. 9, p. 36). The total capacity equals 84,000

gallons. The total capacity of the twelve tanks is divided by a factor of 500 from HRS Table 2-5 (Ref. 1, Sec.

2.4.2.1.3).

Volume of Source: 84,000 gallons

2.4.2.1.5 Source Hazardous Waste Quantity Value

According to the HRS Rule, the highest of the values assigned to each source for hazardous constituent quantity

(Tier A), hazardous wastestream quantity (Tier B), volume (Tier C), and area (Tier D) should be assigned as the

source hazardous waste quantity value. As such, volume (Tier C) was the only tier evaluated for Source 10.

Therefore, the volume will be assigned as the source hazardous waste quantity value for Source 10 (Ref. 1, Sec.

2.4.2.1.5).

3.0 GROUND WATER MIGRATION PATHWAY - NOT SCORED

The ground water pathway will not be evaluated because it is not expected to contribute significantly to the site

score. The site score exceeds 28.5 based only on the evaluation of the surface water pathway.

4.0 SURFACE WATER MIGRATION PATHWAY

4.6.1 Migration Components

Overland/Flood Migration to Surface Water Component

Surface water threats that result from overland/flood migration of hazardous substances from the sources at the site

to surface water will be evaluated for the human food chain threat and environmental threat (Ref. 1, Sec. 4.0.1").

The drinking water threat will not be evaluated at this time.

Ground Water to Surface Water Migration Component

The ground water to surface water migration component has not been evaluated because it is not expected to

contribute significantly to the site score. The site score exceeds 28.5 based only on the evaluation of the surface

water pathway.

4.0.2 Surface Water Categories

According to the HRS Rule, Section 4.0.2, coastal tidal waters include: "embayments, harbors, sounds, estuaries,

back bays, lagoons, wetlands, etc., seaward from mouths of rivers and landward from the baseline of the Territorial

Sea." (Ref. 1, Sec. 4.0.2). As such, Sabine Lake will be evaluated as a coastal tidal water body for HRS scoring

purposes (Ref. 1, Sec, 4.0.2).

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

and entirely within the Grassland Coastal Prairie Region of Texas (Ref. 20, p. 3 pp. 3-4). Jefferson County has a

warm, humid climate. Precipitation, which averages about 54 inches annually, is well distributed throughout the year

but is greatest from May to September (Ref. 20, p. 4). The Neches River, one of the major streams in Jefferson

County, drains the eastern part of the county and flows into Sabine Lake (Ref. 20, p. 4).

Major water-using industries for the City of Port Arthur include: petroleum refining, chemical and allied products

manufacturing, lumber and wood manufacturing, and food preparation. Major irrigation uses for the City of Port

Arthur include: rice, soybean, hay and alfalfa, and vegetables (Ref. 21, p. 5). Surface water used for the

aforementioned resources in Port Arthur and irrigation farmers in Jefferson County is provided by the Sam Rayburn

Reservoir, which is managed and supplied through the Lower Neches Valley Authority. The Sam Rayburn Reservoir

is located several counties north of Jefferson County (Ref. 21, pp. 7-8).

The Palmer site is located on the Southeast Industrial Islet, a small peninsula located approximately 0.5 mile west

of the Neches River at the point it enters the Sabine-Neches Canal (Ref. 3, p. 1). Regionally, Sabine Lake not only

receives water from Jefferson County and the basin of the Neches River, but also from the Sabine River. This water

passes into the Gulf of Mexico through Sabine Pass, a body of salt water lying between Jefferson County and

Cameron Parish, Louisiana (Ref. 22, p. 4).

HRS Documentation Record Palmer Barge Line Site

00067 2
SW - Migration Components

Sabine Lake, immediately east of the Palmer site, is considered to be an estuary (Ref. 3, p.l; Ref. 5, p. 13).

Estuaries are unique water bodies where fresh water from rivers, streams, and direct rainfall mix with salt water

from the sea. The typically high levels of biological production in the estuarine ecosystems results primarily from

their shallow, warm coastal waters being enriched by fresh water inflows and associated sediments and nutrients.

This mechanism is enhanced by the barrier islands, which partially isolate the bays from the Gulf of Mexico, keeping

the nutrient-laden waters inside and preventing them from being diluted or quickly washed out to sea (Ref. 21, p. 4).

Sabine Lake is approximately 68 square miles in area (Ref. 23, p. 2). Designated uses of Sabine Lake include

contact recreation, high aquatic life areas, and commercial and recreational fishing (Ref. 23, p. 2; Ref. 29, p.l).

4.1 OVERLAND/FLOOD MIGRATION COMPONENT

4.1.1 General Considerations

4.1.1.1 Hazardous Substance Migration Path for Overland/Flood Migration Component

Overland Segment

The overland segment is defined as, "the portion of the hazardous substance migration path from a source to a

surface water body (Ref. 14, p. 4). The PPE is the point at which the overland flow segment of a hazardous

substance migration path intersects with perennially flowing surface water (Ref. 14, p. 4).

The site is slightly elevated along the western property boundary and gradually slopes toward the east in the direction

of Sabine Lake. Surface water at the site drains in an easterly direction across the site and discharges directly into

Sabine Lake at the bulkhead/dock area (Ref. 9, p. 78). The shortest overland flow segment for hazardous substance

migration from a source at the site to an HRS-eligible surface water body (Sabine Lake) is approximately 80 feet

(Ref. 9, p. 79).

In-Water Segment

The in-water segment is the portion of the hazardous substance migration path from the PPE to the Target Distance

Limit (TDL) (Ref. 14, p. 3). For a coastal tidal water, the TDL is drawn as an arc with a radius of 15 miles and the

direction of flow is not considered (Ref. 14, p. 5). A Surface Water Pathway Map is included as Figure A-7 of

Attachment A and illustrates the in-water segment of the surface water pathway for the Palmer site.

PPE: Bulkhead/Dock at Sabine Lake

One PPE has been identified for the Palmer site. The point at which the overland segment of the hazardous

substance'migration path intersects with surface water, referred to as the PPE, occurs at the bulkhead/dock area

at Sabine Lake. Local topography of the site slopes in an easterly direction toward Sabine Lake.

During the 1999 ESI, a large barge was parked at the bulkhead/dock area. The barge was not present during the

site reconnaissance visit that was performed prior to the ESI field activities (Ref. 9, p, 22). The bulkhead/dock area,

and thus the PPE is approximately 300 feet in length, as illustrated on Figure A-3 of Attachment A.

In-Water Segment: Sabine Lake

The in-water segment of the hazardous substance migration path, from the PPE to the 15-mile TDL, begins and ends

within Sabine Lake.

HRS Documentation Record Palmer Biuge Line Site

05/03/00 69 TXD068104561

00067 3
4.1.1.2 Target Distance Limit (TDL)

The TDL defines the maximum distance over which targets are considered in evaluating a site (Ref. 1, Sec. 4.1.1.2).

According to the HRS Rule, if there is an observed release from the site to surface water, in the watershed being

evaluated, that is based on sampling, begin measuring the TDL for the watershed at the PPE and extend the TDL

either for 15 miles along the surface water or to the most distant sample point that meets the criteria for an observed

release, whichever is greater (Ref. 1, Sec. 4.1.1.2). At the Palmer site, the TDL is the distance from the PPE to

an arc with a radius of 15 miles in Sabine Lake.

4.1.1.3 Evaluation of Overland/Flood Migration Component

One hazardous substance migration path and one watershed (Sabine Lake) have been identified for the surface

water pathway for the Palmer site. Thus, the overland/flood migration component will be evaluated for the Sabine

Lake watershed based on three facior categories: Likelihood of Release, Waste Characteristics, and Targets (Ref.

1, Sec. 4.1.1.3).

4.1.2 Drinking Water Threat - Not Evaluated

Drinking water intakes have not been identified within the TDL of the surface water pathway established for the

Palmer site. Therefore, the drinking water threat for the overland/flood migration component was not evaluated.

4.1.3 Human Food Chain Threat

4.1.3.1 Human Food Chain Threat - Likelihood of Release

Specific information related to sediment samples that meet the criteria for an observed release for the human food

chain threat are presented and discussed in the subsections below.

Observed Release

The surface water pathway is the only pathway being scored for the Palmer site. Metals attributed to the facility

have been released to Sabine Lake. An observed release to the surface water pathway was established based on

analytical evidence of hazardous substances per HRS Rule, Sections 2.3 and 4.1.2.1. Information used to establish

an observed release from overland/flood migration to the surface water pathway from sources at the site is presented

in the following subsections.

Direct Observation: Not Applicable.

Chemical Analysis:

Development of Sediment Background Levels

A total of five sediment samples (stations 034 through 037 and 055) were collected during the 1999 ESI from Sabine

Lake in an effort to characterize background conditions within the vicinity of the site. Background sediment samples

were collected within Sabine Lake immediately south/southeast of Stewt's Island. These sediment samples were

collected approximately 4,000 feet north/northeast of the Palmer site (See Figure A-6). This portion of Sabine Lake

is not considered to receive runoff from the site based on its location (Ref. 3, p. 1).

HRS Documentation Record Palmer Barge Line Site

05/03/00 70 TXD068104561

00067 4
water from the Gulf flows in, fills the lake, and ascends for miles into the nearby rivers and streams (Ref.22, p. 4).

This extensive tidal mixing implies that Sabine Lake is well mixed, increasing the likelihood that the background

sediment samples capture both the inflow from the Neches River and the tidal influence from the Gulf of Mexico.

The background sediment samples were collected near Stewt's Island, in a portion of Sabine Lake which has

comparable flow characteristics to the area just off of the Southeast Industrial Islet where the observed release

samples were collected.

The background sediment samples were collected from Sabine Lake in a boat, using a stainless steel Ponar«

sediment sampler. A sufficient amount of sediment was collected from Sabine Lake and placed into a dedicated

mixing bowl. The sediment was homogenized and placed in appropriate sample containers, labeled with time and

date, and placed into a cooler with ice (Ref. 9, p. 22). The non-disposable sampling equipment used during the

sediment sampling collection process was decontaminated before initial use, between uses at successive sample

locations,-and at each sample station location. Non-disposable sampling equipment was scrubbed in potable water

containing non-phosphate detergent and rinsed with potable water (Ref. 9, p. 23).

M background sediment samples were analyzed for all target compound list (TCL) and target analyte list (TAL)

substances per the USEPA Contract Laboratory Program (CLP) statement of work (Ref. 9, p. 25). QA/QC

summary forms, result summaries, and chain of custody forms for the sediment samples used to determine sitespecific background concentrations for the surface water pathway are included in Reference 25.

The background sediment samples collected during the 1999 ESI, and designated as such in this documentation

record, are considered to be representative of background conditions within Sabine Lake. There does not appear

to be any known commercial or industrial operations occurring on Stewts Island (Ref. 3, p. 1).

Site-specific sediment background concentrations determined for the Palmer site are presented in Table 12. Three

times the maximum concentration of each substance detected in all background samples was designated as the sitespecific sediment background concentration. Qualified data may be used when it can be demonstrated that the data

meet the MRS Rule for determining an observed release despite the bias in the reported concentrations. As such,

the qualified data was considered usable for scoring purposes after the appropriate action was taken as outlined in

the "Using Qualified Data to Document an Observed Release" Factsheet (Ref. 34). Thus, the site-specific

background concentrations determined for the Palmer site are depicted by the underlined values in Table 12.

Observed Release Samples

Sediment samples were collected to confirm the presence of site-related contamination in Sabine Lake due to

potential site releases and surface water run-off. As part of the 1999 ESI, a total of 17 sediment samples were

collected for characterization purposes. The 17 sample locations (stations 038 through 054) were situated within

Sabine Lake adjacent to the Palmer site (Ref. 9, p. 22). The sediment samples were generally concentrated near

the northern and southern ends of the bulkhead [See Figure A-5]. It should be noted that during the ESI field

activities, a barge was moored at the bulkhead of the Palmer site. The barge was not present during previous site

reconnaissance visits, therefore, the original sediment sample locations were readjusted in the field after consultation

with USEPA Region 6 personnel (Ref. 9, p. 22).

The release sediment samples were collected from Sabine Lake in the same manner as the background sediment

samples - in a boat using a stainless steel Ponar, sediment sampler. A sufficient amount of sediment was collected

from Sabine Lake and placed into a dedicated mixing bowl. The sediment was homogenized and placed in

appropriate sample containers, labeled with time and date, and placed into a cooler with ice. The non-disposable

sampling equipment used during the sediment sampling collection process was decontaminated before initial use,

between uses at successive sample locations, and at each sample station location. Non-disposable sampling

equipment was scrubbed in potable water containing non-phosphate detergent and rinsed with potable water (Ref.

9, p. 22).

All sediment samples collected for characterization purposes were analyzed for all target compound list (TCL) and

target analyte list (TAL) substances per the USEPA Contract Laboratory Program (CLP) statement of work (Ref.

9, p. 25). QA/QC summary forms, result summaries, and chain of custody forms for the sediment samples used to

document an observed release to the surface water pathway are included in References 25 and 26.

Sediment sample results used to document an observed release to the surface water pathway at the Palmer site are

presented in Table 13. Site-specific sediment background concentrations determined for the Palmer site have also

been presented in Table 13. Three times the maximum concentration of each substance detected in all background

samples was designated as the site-specific sediment background value. As such, an observed release will be

established when the sample measurement equals or exceeds three times the maximum background concentration.

If the background concentration is not detected, an observed release is established when the sample measurement

equals or exceeds the SQL (Ref. 1, Table 2-3). Underlined results presented in Table 13 meet observed release

criteria per HRS Rule, Section 2.3 (Ref. 1, Sec. 2.3).

Primary operations conducted at the Palmer site included cleaning, degassing, and maintenance and inspection of

barges and other marine equipment. Typical cleaning operations, also referred to as stripping, included the removal

of sludge, liquid (heels), and all other residual constituents. This cleaning was accomplished by pressure steaming

the vessel holds, engines, and boilers. Degassing activities involved the removal of explosive vapors from the barge

hold using nitrogen or boiler exhaust. Maintenance and inspection activities included the replacement and/or repair

of valves, engines, and line leaks followed by pressure tests and fracture assessments. Reportedly, Palmer Barge

Line, Inc. utilized two diesel/mixed fuel boilers to produce low-pressure steam to aid in the cleaning of barges.

Engines were degreased and residuals spilled during the loading and unloading of the barges were stored on site hi

slop tanks (Ref. 5, pp. 4-5; Ref. 7, p. 2; Ref. 9, p. 6).

Structures at the site include various-sized steel ASTs, several open-top slop tanks, roll-off boxes, and 55-gallon

drums (Ref. 5, p. 8; Ref. 9, p. 6). Free standing oily liquids and stained soils have also been observed at the site (Ref.

5, Health and Safety Plan, p. 4). A detailed description of each of the above structures, as well as additional

structures not previously mentioned, is presented in the following paragraphs. A Site Plan is provided as Figure A-3

of Attachment A

Four ASTs are located in the northeastern portion of the site. The four ASTs, one estimated at 25,000 gallon

capaciy and three 5,000 gallon capacity tanks, are constructed of steel and surrounded by an earthen berm

measuring approximately 90 feet by 50 feet by 3 feet high (Ref. 5, p. 8; Ref. 9, p. 7). These four ASTs were used

for bulk waste storage during barge cleaning operations at the site. The four ASTs are rusting near the base and

are believed to be full of unknown liquids. One foot of oily liquid was observed inside the berm during a site visit

conducted in 1998 (Ref. 9, p. 7).

Four ASTs are located adjacent to the boiler house in the southwestern portion of the property (Ref. 5, pp. 5, 8).

The estimated capacity of each of these ASTs is 7,000 gallons and the ASTs are reportedly full of liquid. Three of

the four ASTs reportedly were used to store liquids as a fuel source for two boilers to produce steam during site

operations (Ref. 5, pp. 5, 8; Ref. 9, pp. 7-8). The fourth AST was reportedly used for freshwater storage. It is

believed that diesel and other petroleum-type products were stored in the ASTs (Ref. 6, p. 8; Ref. 9, p. 8). The

ASTs are located directly on the ground and no containment features are associated with these ASTs. Numerous

pipes and valves were observed to connect the ASTs, some of which were reported to have leaked to the

surrounding soil (Ref. 9, p. 8).

Four open-top slop tanks and five closed slop tanks are located on site. The open-top slop tanks are located west

of the flare and consist of steel containers full of an oily material. These slop tanks each measure approximately 8

feet by 5 feet by 4 feet (or 6 cubic yards) (Ref. 9, p. 8). The soil below the slop tanks is stained and stressed

vegetation has been noted. The open-top slop tanks are situated directly on the ground with no secondary

containment present (Ref. 9, p. 8). Three slop tanks are located in the northern portion of the property and the

remaining two tanks are located in the eastern portion of the property (Ref. 9, p. 8).

Three horizontal ASTs are located near the southeast comer of the site. The estimated capacity of the three tanks

is 10,000 gallons each. A concrete berm, measuring approximately 30 feet by 30 feet by 1 foot high, surrounds the

three ASTs and contained an unknown greenish-colored liquid during the most recent field activities conducted in

October 1999 (Ref. 9, p. 7). The tanks are believed to be full of liquid and were probably used as part of the barge

cleaning and degassing system. Stained soils are present around the berm and appear to be the result of tank

overflow (Ref. 9, p. 7).

HRS Documentation Record Palmer Baige Line Site

SW-Attribution

Twelve ASTs are located in the eastern portion of the site. All of the ASTs are identical in size (estimated capacity

is 7,000 gallons each) and shape and are surrounded by a concrete berm measuring approximately 95 feet by 30 feet

by 1 foot high (Ref. 5, p. 5; Ref. 9, p. 7). An oily liquid was observed inside the berm in October 1999, although the

tanks did not appear to be leaking (Ref. 5, p. 5; Ref. 6, p. 5; Ref. 9, p. 7). There are numerous pipes and valves

connecting the tanks which most likely aided in the liquid transfer and separation activities (Ref. 9, p. 7). The tanks

appeared to be in good physical condition as no rusting or leaking was observed during the October 1999 field

activities. However, stained soil was observed around the concrete berm and appears to be the result of tank

overflow (Ref. 5, p. 10; Ref. 9, p. 7).

A flare, located generally in the central portion of the site, was used to burn excess gasses and liquids produced

during site operations (Ref. 9, p. 8). Areas of concern include stained soils immediately below and around the flare

stack (Ref. 5, p. 10).

One roll-off box is located east of the 12-tank AST battery. The roll-off box contained a dark, oily sludge (Ref. 5,

p. 5). An abandoned vacuum truck was noted near the bulkhead in the eastern portion of the site. The contents of

the vacuum truck are unknown (Ref. 6, p. 5). An oil/water separator, consisting of two ASTs, is located directly

southwest of the 12-tank AST battery (Ref. 9, p. 9).

Additional areas of concern include miscellaneous 55-gallon drums, compressed gas cylinders, paint cans and

buckets, all of whose contents are unknown (Ref. 9, p. 8). Two rectangular-shaped ASTs, each approximately 150

gallons, are located within the vicinity of the 12-tank AST battery. These ASTs most likefy served as fuel tanks and

contained diesel, which was used for site vehicle refueling (Ref. 6, pp. 5-6; Ref. 9, p. 9).

In December 1996, the TNRCC Region 10 field office conducted a multi-media investigation of the Palmer site. The

primary purpose of the investigation was to determine the facility's air compliance status with the FCAA (Ref. 9,

p. 9). The Palmer site operated under two permit exemptions: permit exemption X-3226 and X-3346. According to

permit exemption X-3226, issued on 7 January 1982, the following products were stored within the 12-tank AST

battery: fuel oil, gasoline, naphtha, and toluene (Ref. 7, pp. 2,3). Additional sampling of the various tanks on site had

been performed by the time this documentation record was prepared, but the analytical results are still pending.

As listed in permit exemption X-3346, compounds expected to be encountered during barge cleaning operations

include: alcohols, crude oil, diesel, gasoline, kerosene, jet fuel, mineral oils, naphtha, marine diesel, toluene, and lube

oil (Ref. 7, p. 28). Records reviewed by TNRCC personnel revealed numerous other compounds not represented

in the permits have been serviced at this facility, including: ammonia, cyclohexane, adiponitrile, propylene, butadiene,

and hexane (Ref. 7, pp. 28-30).

In March 1998, the TNRCC Region 10 field office, in cooperation with the USEPA Region 6, prepared a PA/SSI

for the Palmer site. Various waste source areas were identified by the TNRCC during this particular investigation

which are believed to be the result of historical site operations. A total of thirteen soil and twelve sediment samples

were collected and analyzed as part of this investigation (Ref. 5, pp. 24-25). Analytical results for these samples

indicated that several metals were detected in both surface soil and sediment samples collected from various areas

of the site and in the adjacent Sabine Lake (Ref. 9, p. 10). This report has been provided as Reference 5.

In July 1999, a contractor under the direction of the TNRCC Region 10 sampled a majority of the ASTs, roll-off

boxes, and slop tanks located at the site for characterization purposes. The samples collected were analyzed for

TCLP characteristics only for volatiles, semivolatiles, pesticides/PCBs, and metals (Ref. 9, p. 10). The TCLP

identifies the potential for a substance to leach from the sampled material. Analytical results from these samples

indicated several compounds that exceeded the PQL used by the laboratory for comparison purposes. These

HRS Documentation Record Palmer Barge Line Site

SW - Human Food Chain Threat

compounds included: barium, lead, 2-methylphenol, 3 & 4-methylphenols, benzene, and 2-butanone. This report and

analytical results have been provided as Reference 8.

In October 1999, a contractor under direction of the USEPA Region 6, performed an ESI at the Palmer site hi an

effort to determine the presence and nature of contamination hi known or suspected on site and off site locations.

Additionally, migration routes and routes of exposure of site-related constituents were determined for the site (Ref.

9, p. 2). The ESI field activities focused on the collection of soil, ground water, and sediment samples (Ref. 9, p. 3).

Laboratory analytical results for samples collected during the ESI confirmed the presence of site-related

contaminated soil and, to a lesser extent, contaminated ground water, in several source areas at the site. Site-related

contaminants of concern include metals (Ref. 9, p.31-39). Further, laboratory analytical results for sediment samples

obtained from Sabine Lake confirmed that site-attributable contamination was present in Sabine Lake (Ref. 9, p. 80).

The 1999 ESI also suggested the presence of pesticides and other organic compounds, including polycyclic aromatic

hydrocarbons (PAHs), pentachlorophenol (PCP), and benzene (Refs. 10, 16, 18, 19, 24). This report has been

provided as Reference 9.

Based on observations made during the October 1999 ESI, the majority of the sources identified for the site have

insufficient or non-existent containment features. None of the sources identified have secondary containment

features that would prevent or contain a release of hazardous substances in the event that they become flooded (Ref.

9, pp. 79-80). Further, the site is located within the 100-year fioodplain and the average annual rainfall forJefferson

County is approximately 54 inches (Ref. 9, p. 79; Ref. 20, p. 4).

The State Marine of Port Arthur site is located on Old Yacht Club Road, also on Southeast Industrial Islet (also

known as "Pleasure Islet"), immediately south of the Palmer Barge site (Ref. 27, p. 8; Ref. 35, p. 3). The State

Marine site is currently listed on the USEPA's National Priorities List (i.e., Superfund). Both State Marine and

Palmer Barge Line are owned by the same individual (Ref. 35, p.3). In an October 16, 1999, letter to Texas

Senator Phil Gramm, the owner of both sites stated that "if there is any contamination in Sabine Lake it has come

from the adjacent shipyard [Palmer Barge Line site] rather than my original property [State Marine site]" (Ref. 35,

p.3).

Potential to Release

According to the HRS Rule, potential to release is evaluated only if an observed release cannot be established for

the watershed of concern (Ref. 1, Sec. 4.1.2.1.2). As such, the potential to release section for the surface water

migration pathway will not be evaluated since an observed release has been documented at the Palmer site.

4.1.3.2 Human Food Chain Threat - Waste Characteristics

Specific factors related to waste characteristics associated with sources at the site are presented in Section 2.0 of

this documentation record. According to the HRS Rule, a combined toxicity/persistence/bioaccumulation factor value

is determined for the hazardous substances being evaluated for the human food chain threat (Ref. 1, Sec. 2.4.1.2).

As such, a discussion of. each separate factor value is presented in the following subsections. Factor values for

toxicity, persistence, and bioaccumulation are presented in Table 14, as well as the appropriate calculations for the

Human Food Chain Threat.

4.1.3.2.1 Toxicity/Persistence/Bioaccumulation

4.1.3.2.1.1 Toxicity

According to the HRS Rule, toxicity is evaluated for those hazardous substances at the site that are available to a

pathway being scored (Ref. 1, Sec. 2.4.1.1). Toxicity values for hazardous substances are assigned in the Superfund

Chemical Data Matrix (SCDM) and presented in Table 14 (Ref. 2).

4.1.3.2.1.2 Persistence

According to the HRS Rule, a persistence factor value is assigned to each hazardous substance based primarily on

the half-life of the hazardous substances in surface water and secondarily on the sorption of the hazardous

substances to sediments (Ref. 1, Sec. 4.1.2.2.1.2). Persistence values for hazardous substances are assigned in

SCDM and presented in Table 14.

4.1.3.2.1.3 Bioaccumulation Potential

The bioaccumulation potential factor value (BPFV) reflects the tendency for a substance to accumulate in the tissue

of an aquatic organism. The greater the BPFV, the greater the relative tendency of a substance to accumulate (Ref.

14, p. 6). BPFVs for hazardous substances are assigned in SCDM and presented in Table 14 (Ref. 2).

4.1.3.2.1.4 Calculation of Toxicity/Persistence/Bioaccumulation Factor Value

According to the HRS Rule, a toxicity factor is assigned per HRS Table 4-12 based on the product of the values

assigned to the hazardous substance for the toxicity and persistence factors (Ref. 1, Sec. 4.1.3.2.1.4). Based on a

toxicity factor of 10,000 and a persistence factor of 1, a toxicity/persistence factor value of 10,000 was assigned for

mercury per HRS Table 4-12 (Ref. 1, Sec. 4.1.3.2.1.4, Table 4-12).

HRS Documentation Record

SW - Human Food Chain Threat

Toxicity/Persistence Factor Value: 10,000

According to the HRS Rule, a toxicity/persistence/bioaccumulation factor value is assigned per HRS Table 4-16

based on the product of the values assigned for the toxicity/persistence and bioaccumulation potential factors

(Ref. 1, Sec. 4.1.32.1.4; Ref. 2). The hazardous substance with the highest value is assigned as the

toxicity/persistence/bioaccumulaton factor value for the watershed (Ref. 1, Sec. 4.1.4.2.1.4). Based on a

toxicity/persistence factor value of 10,000 and a bioaccumulation factor value of 50,000 for mercury, a

toxicity/persistence/bioaccumularion factor value of 500,000,000 is assigned for the watershed per HRS Table 4-

16 (Ref. 1, Sec. 4.1.3.2.1.4, Table 4-16).

Toxicity/Persistence/Bioaccumulation Factor Value: 5 x 10s

4.1.3.2.2 Hazardous Waste Quantity

Specific information relating to the hazardous waste quantity for the watershed being evaluated is presented in

Section 2.4 of this documentation record. If any target for a migration pathway is subject to Level I or Level n

concentrations, either the value from HRS Table 2-6 or a value of 100, whichever is greater, is assigned as the

hazardous waste quantity factor value for the pathway. The source hazardous waste quantity values for Sources

1 through 10 were summed and the value of 100 was assigned from HRS Table 2-6 (Ref. 1, Sec. 2.4.2.2).

Hazardous Waste Quantity Factor Value: 100

4.1.3.2.3 Calculation of Human Food Chain Threat - Waste Characteristics Factor Category

Value

According to the HRS Rule, the waste characteristics factor category is calculated, for the watershed being

evaluated, based on its toxicity/persistence factor value and BPFV (Ref. 1, Sec. 4.1.3.2.3). The product of the

toxicity/persistence factor value of 10,000 and the hazardous waste quantity factor value of 100 is multiplied by

the BPFV (50,000), resulting in a waste characteristics factor category value of 5 x 10'° (Ref. 1, Sec. 4.1.3.2.3;

Ref. 2). Based on this result, a value is selected from HRS Table 2-7 as the human food chain threat - waste

characteristics factor category value for the watershed being evaluated. As such, a value of 320 is assigned

(Ref. 1, Sec. 4.1.3.2.3, Table 2-7).

Human Food Chain Threat - Waste Characteristics Factor Category Value: 320

4.1.3.3 Human Food Chain Threat - Targets

According to the HRS Rule, the following target factors for each watershed of concern are evaluated: food

chain individual and population (Ref. 1, Sec. 4.1.3.3). A fishery is defined as "any area of a surface water body

from which human food chain organisms are taken or could be taken for human consumption on a commercial,

recreational, or subsistence basis" (Ref. 14, p. 6). A fishery, or a portion of a fishery, has been documented to

be present within the TDL.

Commercial fishing occurs within the coastal waters of Sabine Lake (Ref. 28, pp. 7, 9, 12; Ref. 29, p. 1). The

Texas Parks and Wildlife Department (TPWD) has monitored the commercial landings and value of marine

fishes, oysters, crabs, and shrimp through a mandatory self-reporting system known as the Monthly Aquatic

Products Report (MAPR). Commercial fishing is an important industry in Texas (Ref. 28, pp. 7, 9).

. SW- Human Food Chain Threat

The value of the bay fishing relies primarily on shrimp, blue crabs, Eastern oysters, and finfish (Ref. 28, p. 10).

Sabine Lake has been designated as a high aquatic Life area (Ref. 23, p. 2).

According to the TPWD, Sabine Lake within the vicinity of the Palmer site is also heavily fished on a

recreational basis due to the mixing of fresh water and salt water at the mouth of the Neches River. The area is

popular for recreational fishing because of the wide variety of both fresh water and salt water fish that occur

within this mixing zone (Ref. 29, p. 1; Ref. 30, p. 1).

4.1.3.3.1 Food Chain Individual

Based on analytical results of sediment samples collected from Sabine Lake, a portion of the Sabine Lake fishery

has been documented to be subject to Level n concentrations. Therefore, a value of 45 has been assigned for

the food chain individual factor. (Ref. 1, Sec. 4.1.3.3.1).

Food Chain Individual: 45

4.1.3.3.2 Population

4.1.3.3.2.1 Level I Concentrations

Tissue samples from essentially sessile, benthic human food chain organisms from Sabine Lake have not been

collected. Therefore, Level I concentrations for a fishery have not been established (Ref. 1, Sec. 4.1.3.3.2.1).

4.1.3.3.2.2 Level II Concentrations

Since hazardous substances having a BPFV of 500 or greater (chromium, lead, nickel, and zinc) are present in

sediment samples that meet the criteria for an observed release to the watershed, a portion of the Sabine Lake

fishery is subject to actual, Level n contamination. (Ref. 1, Sec. 4.1.3.3).

Commercial fishing is an important industry in Texas. The average annual production for Sabine Lake, as a

commercial fishery, has been conservatively estimated based on MAPR fisheries production data from 1972 to

1992. The total production provided represents the weight (in pounds) of several fish and crustacean species,

including: flounder, black drum, brown and pink shrimp, white shrimp, and blue crab (Ref. 28, p. 12).

According to the TPWD, Sabine Lake within the vicinity of the Palmer site is also heavily fished on a

recreational basis due to the mixing of fresh water and salt water at the mouth of the Neches River. The area is

popular for recreational fishing because of the wide variety of both fresh water and salt water fish that occur

within this mixing zone (Ref. 29, p. 1; Ref. 30, p. 1).

A fishery, or a portion of a fishery, has been documented in Sabine Lake within the 15-mile TDL established for

the Palmer site. The annual production for the amount of fish and shellfish captured commercially from Sabine

Lake was apportioned to that area of Sabine Lake determined to be subject to Level II concentrations based on

the locations of sediment samples meeting Level II observed release criteria. Sediment samples meeting Level

II observed release criteria were identified and an arc was drawn from the PPE to the furthest sediment sample

subject to Level II concentrations (sample stations 039 and 049). Based on this delineation, an arc with a radius

of 0.06 miles was determined to be subject to Level II concentrations. This delineation is depicted on Figure A-8

of Attachment A

Sabine Lake is approximately 68.7 square miles (Ref. 23, p. 2). Sabine Lake, therefore, has 43,968 acres (i.e.,

68.7 square miles x 640 acres/square mile). The estimated annual production for the entire Sabine Lake is

667,940.5 pounds captured commercially (Ref. 28, p. 12). Approximately 0.18 square miles (i.e., 0.06 mile x 3

mile within nearshore zone) has been determined to be subject to Level II contamination. This equates to 115.2

acres (i.e., 0.18 square miles x 640 acres/square mile). Based on the total estimated annual production of

667,940.5 pounds and a total area of 43,968 acres, there are approximately 15.19 pounds offish captured

commercially per acre within Sabine Lake. Thus, the 115.2 acres subject to Level II concentrations corresponds

to an estimated commercial annual production of 1750 pounds.

The amount of fish caught recreationally could not be estimated accurately. However, based on conversations

with representatives from the Texas Parks and Wildlife Department, recreational fishing occurs heavily within

Sabine Lake. Therefore, based on the estimated annual production of 1750 pounds captured commercially, the

annual production subject to Level II concentrations for commercial fishing is greater than 1,000 pounds per

year.

Based on the total estimated annual human food chain production presented in the table above, a human food

chain population factor value of 3 was assigned per HRS Table 4-18 (Ref. 1, Sec. 4.1.3.3.2.2, Table 4-18). As

such, a value of 3 will be assigned as the Level n concentration factor value.

Level II Concentration Factor Value: 3

4.1.3.3.2.3 Potential Human Food Chain Contamination

Based on the MAPR data provided for species captured commercially from Sabine Lake and the fact that

Sabine Lake is fished heavily for recreational purposes, it was conservatively assumed that an estimated annual

production of 649,841.23 pounds for fish and shellfish captured commercially and 20,000 pounds of fish and

shellfish captured recreationally were subject to potential contamination (Ref. 28, p. 12; Ref. 29, p.l). This total

annual production estimation of 669,841.23 pounds yields an assigned human food chain population value of 310,

from HRS Table 4-18 (Ref. 1, Sec. 4.1.3.3.2.3, Table 4-18).

The human food chain population value is then multiplied by the appropriate dilution weight provided in HRS

Table 4-13 (Ref. 1, Sec. 4.1.3.3.2.3). This product is then divided by 10 and the result is assigned as the potential

contamination value for the human food chain (Ref. 1, Sec. 4.1.3.3.2.3).

Calculation: 310 x 0.0001 = 0.031

0.031 x 0.1 =0.0031

Potential Contamination Factor Value: 0.0031

4.1.3.3.2.4 Calculation of Population Factor Value

According to the HRS Rule, the population factor is calculated by summing the values for Level I concentrations,

Level II concentrations, and potential human food chain contamination factors for the watershed being evaluated.

This sum is not rounded to the nearest integer (Ref. 1, Sec. 4.1.3.3.2.4). As such, a value of 3.0031 was

assigned as the population factor value.

Population Factor Value: 3.0031

4.1.3.3.3 Calculation of Human Food Chain Threat - Targets Factor Category Value

According to the HRS Rule, the human food chain threat targets factor category value is calculated by summing

the food chain individual (45) and population factor value (3.0031) for the watershed being evaluated (Ref. 1,

Sec. 4.1.3.3.3). As such, a value of 48.0031 is assigned as the human food chain threat targets factor category

value.

4.1.3.4 Calculation of Human Food Chain Threat Score for a Watershed

According to the HRS Rule, the human food chain threat score for the watershed being evaluated is calculated

by multiplying the human food chain threat factor category values for likelihood of release, waste

characteristics, and targets for the watershed. This product is rounded to the nearest integer and divided by

82,500 (Ref. 1, Sec. 4.1.3.4). This resulting value, subject to a maximum of 100, is assigned as the human food

chain threat score for the watershed (Ref. 1, Sec. 4.1.3.40.

Calculation: 550 x 320 x 48.0031 782,500 = 102.406 (subject to a maximum of 100)

Human Food Chain Threat Score for a Watershed: 100

Specific information related to sediment samples that meet the criteria for an observed release for the

environmental threat are presented in Table 15 of Section 4.1 of this documentation record.

4.1.4.1 Environmental Threat - Likelihood of Release

An observed release to the surface water pathway was established in Section 4.1.3.1 for the human food chain

threat based on analytical evidence of hazardous substances. According to the HRS Rule, the same likelihood

of release factor category value is assigned for each threat within the surface water pathway (Ref. 1, Sees.

4.1.2.1.3, 4.1.3.1, and 4.1.4.1). As such, a value of 550 is assigned for the likelihood of release factor category

value for the environmental threat.

ecosystem toxichy/persistence/bioaccumulation factor value is determined for the hazardous substances for the

environmental threat (Ref. 1, Sec. 2.4.1.2). As such, a discussion of each separate factor value is presented in

the subsections below. Factor values for ecosystem toxicity, persistence, and bioaccumulation have been

presented in Table 15, as well as the appropriate calculations for the Environmental Threat.

According to the HRS Rule, toxicity is evaluated for those hazardous substances at the site that are available to

a pathway being scored (Ref. 1, Sec. 2.4.1.1). Ecosystem toxicity values for hazardous substances are

assigned in SCDM and presented in Table 15 (Ref. 2).

4.1.4.2.1.2 Persistence

According to the HRS Rule, a persistence factor value is assigned to each hazardous substance based primarily

on the half-life of the substance in surface water and secondarily on the sorption of the hazardous substance to

sediments (Ref. 1, Sec. 4.1.4.2.1.2). Persistence values for hazardous substances are. assigned in SCDM and

presented in Table 15 (Ref. 2).

4.1.4.2.1.3 Ecosystem Bioaccumulation Potential

The bioaccumulation potential factor value (BPFV) (environmental) reflects the tendency for a substance to

accumulate in the tissue of an aquatic organism. The greater the BPFV, the greater the relative tendency of a

substance to accumulate (Ref. 14, p. 6). BPFVs for hazardous substances are assigned in SCDM and

presented in Table 15 (Ref. 2).

4.1.4.2.1.4 Calculation of Ecosystem Toxicity/Persistence/Bioaccumulation Factor Value

According to the HRS Rule, an ecosystem toxicity/persistence factor value is assigned per HRS Table 4-20

based on the values assigned to the hazardous substances for the ecosystem toxicity and persistence factors

(Ref. 1, Sec. 4.1.4.2.1.4). Based on an ecosystem toxicity factor of 10,000 and apersistence factor of 1, for

mercury, an ecotoxicity/persistence factor value of 10,000 was assigned per HRS Table 4-20 (Ref. 1, Sec.

4.1.4.2.1.4, Table 4-20).

According to the HRS Rule, an ecosystem toxicity/persistence/bioaccumulation factor value is assigned per

HRS Table 4-21 based on values assigned for the ecosystem toxicity/persistence and ecosystem

bioaccumulation potential factors (Ref. 1, Sec. 4.1.4.2.1.4; Ref. 2). The hazardous substance with the highest

value is assigned as the ecosystem toxicity/persistence/bioaccumulation factor value for the watershed (Ref. 1,

Sec. 4.1.4.2.1.4). Based on a toxicity/persistence factor value of 10,000 and a bioaccumulation factor value of

50,000 for mercury, a toxicity/persistence/bioaccumulation factor value of 5 x 10s was assigned for the Sabine

Lake watershed per HRS Table 4-21 (Ref. 1, Sec. 4.1.4.2.1.4, Table 4-21).

Ecosystem Toxicity/Persistence Factor Value: 10,000

Ecosystem Toxicity/Persistence/Bioaccumulation Factor Value: 5 x 108

4.1.4.2.2 Hazardous Waste Quantity

According to the HRS Rule, the same hazardous waste quantity factor value for the human food chain threat is

assigned as the environmental threat for the watershed (Ref. 1, Sec. 4.1.4.2.2). As such, a hazardous waste

quantity value of 100 is assigned.

Hazardous Waste Quantity: 100

4.1.4.2.3 Calculation of Environmental Threat - Waste Characteristics Factor Category Value

For the hazardous substance selected for the watershed in Section 4.1.4.2.1.4 (mercury), its ecosystem

toxicity/persistence factor value and ecosystem bioaccumulation potential factor value are used to assign a

value to the waste characteristics factor category (Ref. 1, Sec. 4~.\ .4.2.3).

First, multiply the ecosystem toxicity/persistence factor value and the hazardous waste quantity factor value for

the watershed (subject to a maximum of 1 x 10s). Multiply this product by the ecosystem bioaccumulation

potential factor value for the same hazardous substance (subject to a maximum product of 1 x 1012). Based on

this second product, assign a value from HRS Table 2-7 as the environmental threat waste characteristics factor

category for the watershed (Ref. 1, Sec 4.1.4.2.3).

Calculation: 10,000 x 100 = 1,000,000

1,000,000 x 50,000 = 5 x 10'° (subject to a maximum of 1 x 1012)

Thus, based on the above calculation, a value from HRS Table 2-7 is assigned as the environmental threat

waste characteristics factor category value for the watershed being evaluated (Ref. 1, Table 2-7).

4.1.4.3 Environmental Threat - Targets

Sensitive environments along the hazardous substance migration path for the watershed are evaluated based on

three factors: Level I concentrations, Level n concentrations, and potential contamination. Ecological-based

benchmarks are used instead of health-based benchmarks in determining the level of contamination hi samples

(Ref. 1, Sec. 4.1.4.3.1). The ecological-based benchmark values are the USEPA's AWQC and AALAC

values (Ref. 14, p. 8).

Any portion of a listed sensitive environment is subject to actual contamination if it falls within an area that

meets the criteria for an observed release. Only surface water samples may be used to establish Level I

concentrations (Ref. 14, p. 8). Any terrestrial sensitive environments defined by the presence of one or more

particular species (e.g., habitat known to be used by an endangered or threatened species, terrestrial areas used

for breeding by large or dense aggregations of animals) and whose boundaries cross 01 border a surface water

body within the TDL are eligible to be evaluated in the surface water pathway unless there is clear information

that the particular species of concern is unlikely to come into contact with surface water bodies within the TDL

(Ref. 14, p. 7).

4.1.4.3.1.1 Level I Concentrations

Level I concentrations are established in aqueous samples in which the concentration of a hazardous substance

the meets the criteria for an observed release is at or above the appropriate ecological-based benchmark

(AWQC or AALAC) as reported in SCDM (Ref. 2; Ref. 14, p. 8). Level I concentrations can not be

established for the Palmer site as surface water samples were not collected as part of any investigation

conducted at the site.

4.1.4.3.1.2 Level II Concentrations

Level n concentrations are established in samples in which the concentration of at least one hazardous

substance meets the criteria for an observed release, but the conditions for Level I concentrations are not met

(Ref. 1, Sec. 4.1.4.3.1.2). Level II concentrations have been documented within Sabine Lake, however,

environmental targets subject to actual contamination have not been identified.

For those sensitive environments that are wetlands, a value from HRS Table 4-24 is assigned based on the total

length of wetland frontage miles located along the hazardous substance migration path (Ref. 1, Sec. 4.1.4.3.1.3).

Based on the total length of wetland frontage miles for both of the wetland types identified above, a value of

Two bird rookeries have been identified within the 15-mile TDL: Sydney Island and Dooms Island. The Dooms

Island rookery, colony number 601-121, is located approximately 1/4 mile northeast of the site and is a nesting

colony for the black skimmer (Ref. 3, p.l; Ref. 32, p. 4). The Sydney Island rookery, colony number 601-120,

is located approximately 1 1/4 miles northeast of the site and is also a nesting colony for the black skimmer

(Ref. 3, p. 1 Ref. 32, p. 4). Both rookeries are managed by the Texas Parks and Wildlife Department (Ref. 32,

pp. 1, 4-5). Therefore^ this sensitive environment will be evaluated as a terrestrial area utilized for breeding by

large or dense aggregations of animals and will be assigned a value of 75 from the HRS Table 4-23 (Ref. 1,

Table 4-23).

Sensitive Environment Rating Value: 75 x 2 = 150

A search for Federal and State listed threatened and endangered species within a 4-mile radius and 15-mile

downstream distance was performed for the State Marine site. Since the Palmer site is located adjacent to the

State Marine site, the same Federal and State listed threatened and endangered species known to inhabit areas

near the State Marine site were considered to be the same for the Palmer site.

As such, the following Federally listed endangered species have been identified as inhabiting areas near the

Palmer site: Bald eagle, Black rail, Gulf saltmarsh snake, and the Texas diamondback terrapin. These species

are known to inhabit salt, brackish, and fresh water marshes as well as estuaries and coastal bays (Ref. 32, p.

1). As such, a value of 75 will be assigned from HRS Table 4-23 for a habitat known to be used by Federallydesignated endangered species (Ref. 1, Table 4-23).

Sensitive Environment Rating Value: 75 x 4 = 300

The following State-listed threatened species have been identified as inhabiting areas near the Palmer site:

American swallow-tailed kite. This species is known to inhabit marshes along rivers, lakes, and ponds (Ref. 32,

p. 1). As such, a value of 50 will be assigned from HRS Table 4-23 for a habitat known to be used by Statedesignated threatened species (Ref. 1, Table 4-23).

1937 and occupies the marshes between Calcasieu and Sabine lakes in southwest Louisiana. The Sabine

National Wildlife Refuge is the largest coastal marsh refuge on the Gulf of Mexico (Ref. 33, p. 3). The Sabine

National Wildlife Refuge is located approximately 13 miles due east of the site and provides a large area of

coastal wetlands to many wintering and migrating waterfowl. It is also a major nursery area for many

estuarine-dependent marine species as well as being the home for alligators and other reptiles, mammals, and

numerous wading, water and marsh birds (Ref. 33, p. 3; Ref. 14, p. 7). The Sabine National Wildlife Refuge

borders a surface water body within the TDL, therefore it is assigned a sensitive environments rating of 75,

according to the HRS Table 4-23 (Ref. 14, p. 7).

The sum of the sensitive environments rating value for each surface water body is then multiplied by the

appropriate dilution weight provided in HRS Table 4-13 (Ref. 1, Table 4-13). Sabine Lake is considered to be

coastal a tidal water, where flow rate or depth is not applicable when determining a dilution weight. Thus,

Sabine Lake was assigned a dilution weight of 0.0001 per HRS Table 4-13 (Ref. 1, Sec. 4.1.4.3.1.3).

This product is then divided by 10 and the result is assigned as the potential contamination value for the sensitive

environments (Ref. 1, Sec. 4.1.4.3.1.3, Tables 4-13, 4-23, and 4-24).

Calculation: 0.0925x0.10 = 0.00925

If the potential contamination factor value is less than 1, it is not rounded to the nearest integer (Ref. 1, Sec.

4.1.4.3.1.3). As such, a value of 0.00925 is assigned as the potential contamination factor value.

Potential Contamination Factor Value: 0.00925

4.1.4.4 Calculation of Environmental Threat Score for a Watershed

According to the HRS Rule, the environmental threat score for the watershed being evaluated is calculated by

multiplying the environmental threat factor category values for Likelihood of Release, Waste Characteristics,

and Targets for the watershed and dividing by 82,500. The resulting value, subject to a maximum of 60, is the

environmental threat for the watershed (Ref. 1, Sec. 4.1.4.4).

Calculation: 550 x 320 x 0.00925 = 1628

1628/82,500 = 0.01973

Environmental Threat Score for a Watershed: 0.01973

4.L5 Calculation of Overland/Flood Migration Component Score for a Watershed

According to the HRS Rule, the overland/flood migration component score is calculated by summing the scores

for the three threats (drinking water, human food chain, and environmental). The resulting score, subject to a

maximum value of 100, is assigned as the overland/flood migration component score for the watershed being

evaluated (Ref. 1, Sec. 4.1.5).

Calculation: 0 + 100 + 0.01973 = 100.01973 (subject to a maximum of 100)

Overland/Flood Migration Component Score for a Watershed: 100

4.1.6 • Calculation of Overland/Flood Migration Component Score

According to the HRS Rule, the overland/flood migration component score is calculated by selecting the highest

overland/flood migration component score from the watersheds evaluated (Ref. 1, Sec. 4.1.6). The Sabine

Lake watershed was the only watershed evaluated for the Palmer site. As such, a value of 100 is assigned as

the overland/flood migration component score.

Overland/Flood Migration Component Score: 100

4.2 GROUND WATER TO SURFACE WATER MIGRATION COMPONENT

The ground water to surface water migration component will not be scored because on observed release has

been established to the overland/flood migration component of the surface water pathway and is sufficient to

score the site.

4.3 CALCULATION OF SURFACE WATER MIGRATION PATHWAY SCORE

Since only one of the two surface water migration components (overland/flood) has been scored, this score will

be assigned as the surface water migration pathway score (Ref. 1, Sec. 4.3).

Surface Water Migration Pathway Score: 100

5.0 SOIL EXPOSURE PATHWAY

The soil exposure pathway has not been scored even though extensive surface and subsurface contaminated

soils have been identified associated with various onsite source areas. Scoring the surface water pathway alone

is sufficient to score the site.

No residents, schools, or day care facilities have been identified on or within 200 feet of any known source of

contamination. While physically accessible to the public, a majority of the site is heavily vegetated with grasses

and small trees (Ref. 9, p. 88). Several Federal and state threatened and endangered species have been

identified as inhabiting areas within a 4-mile radius of the site or within 15 miles downstream of the site (Ref.

32, p. 1). In addition, two bird rookeries have been identified within the 15-mile TDL determined for the site

(Ref. 9, p. 89; Ref. 32, pp. 1, 4-5). There are no immediate resources associated with the site, as the soils in

which the site is situated are not suitable for cultivation (Ref. 9, p. 88).

6.0 AIR MIGRATION PATHWAY

The air migration pathway has not been scored because the necessary data to document an observed release

are not available. Further, based on available information, evaluation of this pathway would not significantly

affect the overall site score (Ref. 1, Sec. 2.2.3).
