16. Abstract (Umlt: 200 words)
The 16.7-acre PAB Oil & Chemical Services site is an abandoned waste disposal area
located in Vermilion Parish, Louisiana. The site overlies the Chicot Aquifer System
and is part of the Atlantic-Gulf Coastal Plain. Site features include a levee around
the majority of the property, three waste disposal pits: northwest pit, northeast pit,
and south pit, and three surface water bodies: salt water pond, northwest pond, and an
abandoned canal. Land use in the area is mixed rural, agricultural, and residential.
The area residents use 55 wells located within one-half mile of the site. and three
municipal wells located within three miles of the site to obtain their drinking and
irrigation water. From 1978 to approximately 1983, PAB Oil & Chemical Services (PAB
Oil) began site operations as a disposal facility for oil field drilling mud and salt
water, under State interim approval. PAB Oil reportedly sold the waste oil skirmned
from the oil-based drilling mud separation/disposal pits located in the northeast part
of the site to reclaimers. In 1980, the State passed an amendment, which established
new requirements for offsite drilling mud and. salt water disposal facilities. P AB Oil
was granted temporary authority to operate with 90 days to comply with the new
requirements and to obtain a State permit to discharge treated w~ter from

Abstract (Continued)
the disposal pits to the surface water drainage system. Later that year, a citizen's
complaint of an illegal discharge from the site into an offsite drainage ditch led to EPA
and State site investigations. These investigations determined that the majority of the
onsite contamination was a direct result of the drilling mud and fluids, produced water,
.workover fluids, and tank bottoms that the facility received from oil and gas exploration
and production. Other contamination was attributed to pesticides from local agricultural
uses and naturally occurring contamination, such as arsenic in the ground water. In 1982,
PAB Oil reported that it had ceased accepting oil field waste because it could not meet
the new State requirements. As a result, the State revoked PAB Oil's interim authority
and ordered the site to be closed. In 1983, the State notified PAB Oil of its decision to
seal the site's storage tanks and the gates to the facility due to open leakage from pits
and because an unknown party had placed petroleum waste in an onsite tank. In 1983, PAB
Oil went out of business and becasue they lacked the funds necessary for a proper site
closure, abandoned the sight. As a result, the contaminated waste still remained onsite.
In 1984, 1985, and 1987, EPA conducted additional site investigations and, in 1991,
discovered an immediate threat posed by ignitable waste contained in one of four onsite
storage tanks that was structurally damaged. Therefore, in 1992, EPA implemented a
quick-response removal action to relocate the waste from all four storage tanks, dismantle
the tanks, and treat and dispose of the waste offsite. This ROD addresses a first and
final remedy for all the contaminated media that pose a risk by direct contact with the
site or migration of site contaminants into the surrounding environment. The primary
contaminants of concern affecting the soil, sediment, sludge, ground water, and surface
water are VOCs, including benzene and toluene; other organics, including PARs; and metals,
including arsenic, and barium.
The selected remedial action for this site includes excavating and treating onsite
approx~ately 10,900 yd3 of organic-contaminated soil, 520 yd3 of sediment, and 15,500 yd3
of sludge using biological treatment process treating residuals from the bioremediation
process with elevated levels of inorganic contamination using solidification/
stabilization, followed by onsite disposal; utilizing a 2-foot thick, clay cover, or other
suitable cover over the disposal area; collecting and treating onsite approximately
9,187,000 gallons of surface water using granular activated carbon and sand filtration,
followed by onsite discharge to drainage ditches; conducting treatability studies to
determine the appropriate biological treatment process; and post-RA ground.water
monitoring. The estimated present worth cost for this remedial action is $13,113,000,
which includes an estimated annual O&M cost. of $85,900 for 30 years. .
PERFORMANCE STANDARDS OR GOALS:
Soil, sediment, and sludge cleanup goals are based on State and Federal regulations and a
health-based exposure limit of 10-6, and include arsenic 10 mg/kg; barium 5,400 mg/kg; and
total carcinogenic PAHs 3 mg/kg. Surface water cleanup levels are based on State
discharge limits and ambient water quality criteria, and include barium 2,000 ug/l;

STATEMENT OF BASIS AND PURPOSE
This decision document presents the selected remedial action
for the PAB oil and Chemical Services, Inc. Site (hereinafter "PAB
oil site" or the "site"), in Vermilion Parish, Louisiana, which was
chosen in accordance with the Comprehensive Environmental Response,
compensation, and Liability Act of 1980 C"CERCLA"), as amended by
the Superfund Amendments and Reauthorization Act of 1986 ("SARA"),
42 U.S.C. 59601 et sea., and to the extent practicable, the
National Contingency Plan ("NCP"). This decision is based on the
Administrative Record for this site.
The State of Louisiana concurs on the selected remedy.
ASSESSMENT OF THE SITE
Actual or threatened releases of hazardous substances fram
this site, if not addressed by implementing the response action
selected in this Record of Decision ("ROD"), may present an
imminent and substantial endangerment to public health, welfare, or
the environment.
DESCRIPTION OF THE REMEDY
The site is being handled as one operable unit. The principal
concerns to be addressed at the site are fram contaminated sludges,
soil and sediments, surface water, and to a lessor extent, ground
water. The major components of the selected remedy include:
- Removal and on-site treatment of all surface water with
final discharge to site drainage ditches;
- Excavation and biological treatment of organic contaminated
sludges, soils, and sediments;
SOlidification/Stabilization of biologically
residuals to address inorganic contamination
necessary, any remaining organic contaminants;
treated
and, if
- Final disposal of treated residuals in an on-site disposal
-------
- long-term ground water monitoring; and
- long-term site operation and maintenance.
STATUTORY DETERMINATIONS
The selected remedy is protective of human health and the
environment, complies with Federal and State requirements that are
legally applicable or relevant and appropriate to the remedial
action, and is cost effective. This remedy does satisfy the
statutory preference for treatment that reduces toxicity, mobility
or volume as a principal element of the remedy. The selected
remedy utilizes permanent solutions and alternative treatment
technologies to the maximum extent practicable for this site.
Because the remedy may result in hazardous substances remaining on-
site above health-based concentration levels, a review will be
conducted within five years of commencement of the remedial action
to ensure th t the remedy continues to provide adequate protection
of a he th and the environment.

Z. SITE NAME, LOCATIOB AKD DESCRIPTIOB
The PAB oil and Chemical services, Inc. Site ("PAB Oil site" or
"site") is located less than J miles north of Abbevi11e, Louisiana,
adjacent to u.s. Route 167, in Vermilion Parish, Section 12, T12S-
RJE (Figure #1). The property is located in a generally rural area
with the surrounding property being chiefly agricultural with
livestock grazing and crops. Residential use of the surrounding
property has increased however, along the major roadways in close
proximity to the site (u.s. Route 167 to the west and Parish Road
P-J-26 to the south).
The PAB oil site consists of about 16.7 acres with approximately
82% of the site being utilized as pits/ponds and related berms or
levees (Figure #2). The site was used for disposal of oil and gas
exploration and production wastes including drilling muds, drilling
fluids and produced waters. The pits presently contain solid
and/or liquid wastes that have the potential of migrating into the
surrounding environment.
The site and surrounding area are flat and have a general surface
elevation of slightly below +20 ft. mean sea level ("MSL"). The
top of the dispc~a1 pit berms ranqe in beiqbt from approximately
5. J - 6.2 ft above grade, while the berm around the large salt
water pond ranges from 3-5 ft above grade. The si~e i~se1f has a
levee around the majority of the property, ranqinq from 4 ft to the
east alonq a former irriqation canal, to 1-2 ft along the remainder
of the site.
L.
The subsurface cross-sections and boring loqs reveal, for the most
part, three subsurface stratigraphic units: an upper clay unit (2-
20 feet below ground surface), a middle clay/silt/sand unit (20-25
feet below ground surface) and a lower sand/gravel unit (25+ feet
below ground surface. Ground water beneath the site was
encountered at approximately 30 ft. below the ground surface in the
upper Chicot~quifer System.
xx. SXTB BXSTORY ABD ~ORCBKEBT &C!~v~TXB8
Relevant site his~ory dates back to 1978 when PAB oil and Chemical
services, Inc. beqan operating a disposal facility for oil field
drilling muds and salt water on the property. This operation
continued for approximately five years and has since been
abandoned. As part of its normal operations, PAB oil reportedly
sold to rec1aimers the waste oil skimmed from the oil-based
drilling mud separation/disposal pits located in the northeast part
of the site.

.
,
-------
PAB Oil beqan operations in late ~978 and operated under interim
approval, granted by the Louisiana Department of Natural Resources
("LDNR"), Office of Conservation on September 25, 1979. The
approval was qranted under authority of statewide Order 29-B, which
requlates the drillinq, production and operation of oil and qas
wells in the state of Louisiana, includinq provisions for pollution
control.
On July 20, 1980, an amendment to Statewide Order 29-B, which
established new requirements for off-site drilling mud and salt
water disposal facilities, became effective. Existing facilities,
includinq PAB Oil, were qranted temporary authority to operate,
with 90 days to comply with the new requirements. At the same
time, PAB oil was also notified by LDNR that it needed a permit
from the Office of Environmental Affairs in order to discharqe
treated water from the disposal pits into the surface w~ter
drainaqe system.
A citizen's complaint of discharge from the site into an off-site
drainage ditch led to site identification by the Environmental
Protection Aqency ("EPA") on June 27, ~980. As a result, site
inspections were conducted by the EPA, the LDNR and the Louisiana
Department of Environmental Quality ("LDEQ"). The EPA Field
Investigation Team ("FIT") conducted a preliminary assessment and
preliminary sampling inspection in ~980. "Notices of Violation" of
Statewide Order 29-B were sent to PAB oil on December 4, 1980, by
the LDEQ and on October 2, ~980, by the LDNR.
On January 8, 198~, the Vermilion Parish Police Jury and the
Vermilion Parish Planninq Committee, at the urging of the vermilion
Association to Protect the Environment ("VAPE"), requested that the
LDNR deny PAB Oil's request for a permit to discbarqe treated oil
field wastewater into Coulee Kinney via the Parish drainage system.
PAB oil was aqain notified of violations of statewide Order 29-B on
June 30, ~98~, by the LDEQ and on March 30, 1982, by the LDNR.
PAB oil was owned by Alex Abshire until February ~982, when it was
reported as sold to a consortium headed by william H. L~nnNlo-It and
Jack Clothier. PAB oil reported that 'it stopped receiving oil
field waste in Auqust ~982, because of its inability to meet the
requirements of statewide Order 29-B. Its interim authority to
operate the disposal site was revoked by the LDNR on November 10,
1982, and PAB oil was ordered to proceed with a closure plan for
the site.
On January 12, 1983, PAS oil was notified that the storage tanks
and the qates to the facility had been sealed by aqents of the
LDNR, Office of Conservation, due to open leakaqe from pits and
because an unknown party had placed petroleum waste in a tank at
the site on or about January 10, 1983. All notices of violations
from both departments were referred to the state Attorney General's
office for prosecution in January 1983. Adjoininq property owners
-------
had also filed private lawsuits against PAB Oil alleging salt water
contamination of private water wells and surface property damage.
In 1983, the company reportedly lacked the funds for a proper
closure. It is now out of business and the wastes are still on-
site. PAB Oil's lease was canceled in November 1984, and control
of the property was returned to land owner Edmond Mouton. Mr.
Mouton has since passed away and the property is part of his
Estate.
At the request of EPA, the Technical Assistance Team inspected the
site on November 20, 1984, and FIT conducted comprehensive sampling
at the site on July 9 and 10, 1985. In May, 1986, the FIT was
tasked by the EPA to obtain additional information regarding the
location and description of the City of Abbeville water wells and
the use of surface water in the vicinity of the site. In 1987, the
FIT performed an Expanded Site Inspection ("ESIn). Based in part
on the findings from these investigations, the site was proposed to
the Superfund National Priority List ("NPL") in June 1988. The
site was finalized on the NPL in March 1989.
EPA conducted the Remedial Investigation ("RI") at the site with
assistance from Sverdrup Corporation under the Al ternati ve Remedial
Contract Strategy. RI field activities for the PAB oil site were
conducted from January 14, 1991, to March 29, 1991 (Phase 1) and
from October 7, 1991, to October 31, 1991 (Phase 2). Initial Phase
1 RI field acti vi ties were conducted to evaluate the current
overall environmental impact that has resulted from disposal
activities that occurred during the period that the facility was in
operation. The subsequent Phase 2 RI field activities were
conducted to further define the nature and extent of contaminant
impacts as determined from the results of the Phase 1 RI field
activities. In addition, an evaluation of the potential risks to
human health and the environment from site contaminants was
conducted as part of the RI in the Risk Assessment. The RI Report
was finalized in January 1993.
During the course of the RI sampling, it was discovered that an
emergency situation existed at the site that required immediate
action. This Removal Action was carried out by several of the
site's Potentially Responsible Parties ("PRPs.) under the authority
of an Administrative Order on Consent. The purpose of the Removal
Action was to address the threat posed by iqni table wastes
contained in one of four on-site storage tanks that was
structurally damaged. The action consisted of removing the waste
materials from all four storage tanks, dismantling the tanks, and
treating and disposing the wastes off-site. The scrap metal from
the dismantled tanks was a180 taken from the site. All work was
completed by February 1992.
As mentioned above, several PRPs have been identified at this site.
Approximately 100 PRPs were issued General Notice Letters in August
-------
1989 and RIfFS Special Notice Letters in December 1989. Although
a large portion of these PRPs are viable companies, negotiations
for an enforcement-lead RIfFS were unsuccessful and all work.
conducted at the site thus far (excluding the Removal Action) has
been conducted by the EPA.

The requirements of CERCLA sections 113(k) (2) (B) (i-v) and 177, 42
U.S.C. SS9613(k) (2) (B) (i-v) and 9617, were met during the remedy
selection process, as illustrated in the following discussion.
A series of community interviews near the site were conducted in
May 1990. The interviews included a cross-section of the area
residents and landowners, as well as the Abbeville-Vermilion
Chamber of Commerce, Mayor Broussard, members of the Vermilion
Association to Protect the Environment, and other civic groups. A
site mailing list was developed through the community interview
process and is continually updated as the site acti vi ties progress.
Fact sheets summarizing the progress of the remedial investigation
were mailed out to all individuals on the site mailing list in
January 1992. In December 1992, in conjunction with fact sheets
announcing the completion of the R:IfFS, an informal Open House was
held at the Abbeville General Hospital.
The RIfFS Reports and Proposed Plan for the PAB oil site were
released to the Public on March 22, 1993. The documents were made
available to the public in the Administrative Record File in the
noted information repositories: Vermilion Parish Public Library,
Abbeville, Louisiana; Louisiana Department of Environmental
Quality, Baton Rouge, Louisiana; and the U.S. Environmental
Protection Agency Region 6 Library, Dallas, Texas. A sl1_~ry of
the Proposed Plan and the notice of availability of the these
documents and Administrative Record File was published in the
Abbeville Heridional and Kaplan Herald. In addition, a fact sheet
summarizing the Proposed Plan of Action for the PAS Oil site was
mailed to the site mailing list on March 26, 1993.
The EPA held a public comment period regarding the IUfFS, Proposed
Plan and Administrative Record from March 26, 1993, through April
2S, 1993. During this initial public comment period, a formal
public meeting was held on April 8, 1993, at the Abbeville General
Hospital. Representatives from the EPA presented the remedial
alternatives, the EPA preferred alternative, and answered
questions. All questions and comments were recorded to be included
in the Responsiveness Summary. Due to a request by the Technical
Assistance Grant ("TAG") technical advisor, the public comment
period was extended through May 2S, 1993. The extension was
announced through cards mailed to individuals on the site mailing
list and a newspaper advertisement in the Abbeville Heridional.
-------
A response to all comments received during this 60 day public
comment period, either written or verbally expressed at the public
meeting, is included in the Responsiveness Snmmary (Appendix #1).
The Responsiveness Summary is included as part of the ROD.
This decision document presents the selected remedial action for
the PAB Oil superfund site, in Vermilion Parish, Louisiana, chosen
in accordance with CERCLA, as amended by the Superfund Amendments
and Reauthorization Act and, to the extent practicable, the
National Contingency Plan ("RCP.). The decision for this site is
based on the Administrative Record. An index for the
Administrative Record is included as Appendix #2 to the ROD.
IV. SCOPB AI1D ROLB 01' RBSPOBSB ACTZ08
The remedy to eliminate or minimize the identified threats at the
PAB oil site under this ROD is addressed a8 one operable unit.
This is the only and final operable unit planned for this site. As
mentioned previously, a Removal Action was completed in 1992 at
this site to address former threats associated with four storage
tanks and their contents.
The studies undertaken at the PAB Oil site have identified the
contaminated sludges, soils, sediments, surface water and ground
water as actual or potential threats to human health and the
environment. The threats, or risks posed by these contaminants,
stem from possible ingestion, dermal contact or migration into the
surrounding environment including the underlying ground water which
is a potential drinking water source.
....
EPA defines principal threats as sources of highly mobile or toxic
materials which cannot be kept in place by engineering controls and
represent a risk several orders of magnitude higher than health-
based goals for the site. The sludges contained in the disposal
pits have been identified as the principal threat at the PAB Oil
site because these sludges, if left alone, would continue to be a
potential threat to the ground water through leachate migration and
to human health and the environment through direct exposure.
Low level risk materials are sources of contamination that could be
kept in place by capping and pose a low risk. For example, the
associated soils identified on-site (pond sediments, former tank-
area surficial soils) with less elevated levels ot contamination as
compared to the sludge samples, are considered a low level risk
because of the lower potential for these areas to contaminate the
ground water or pose a direct contact risk to humans.
In addition, the investigations at the site identified potential
human and environmental risks associated with the contaminant
levels found in the surface waters and ground water. Surface water
risks were identified due to potential direct exposure (dermal
5
-------
contact) and ground water risks were identified due to potential
ingestion and dermal contact and inhalation while bathing.
The specific remedial objectives determined to be necessary at the
PAB oil site are:
1. Prevent direct contact, inqestion, and migration of the
dis~osal pit sludges and associated soils.
2.
Prevent direct contact with contaminated surface waters.
3. Prevent the potential for human exposure to contaminated
ground water.

SOJIHAJlY 01' SIT. CDRA~DI8TICS
The PAB Oil site consists of about 16.7 acres with approximately
82% of the site being utilized as pits/ponds and related berms or
levees. The site and surroundinq area are flat and have a qeneral
surface elevation of slightly below +20 ft. MSL. The top of the
disposal pit berms range in heiqht from approximately 5.3 - 6.2 ft.
above qrade, while the berm around the larqe salt water pond ranqe&
from 3-5 ft. above qrade. The site itself has a levee around the
majority of the property, ranqinq from 4 ft. to the east along the
former irriqation canal, to 1-2 ft. alonq the remainder of the
site.
The reqion has an averaqe annual temperature of 20°C, with
temperatures ranqinq from hiqhs of 38°C in July and AUCJUSt to lows
of -7°C in December and January. Rainfall in the area averaqes 59
inches per year, with a mean average annual lake evaporation rate
of 48-50 inches per year.
SURFACE WATER
The majority of surface runoff from the site, includinq overflow
from the salt water ponds, drains to the west in the ditches on
both sides of the site access road. Flow continues along the road
to the u.S. Route 167 drainaqe ditch. Flow then drains to the
north along u.s. Route 167 for approximately 70 ft. before it turns
eastward. The surface water flows eastward for approximately 160
ft. back toward the site before it starts to deviate from its
eastward direction and head in a northern direction, away from the
site.
The precipitation that enters the northwest pit resulting in
overflow spills into the northeast pit through an openinq in the
berm between the two areas. Water then flows to the south pit from
the northeast pit through an interconnecting piPe- The water then
flows from the south pit to the salt water pond through a
connecting pipe.
-------
The salt water pond overtops a low berm/spillway in the
southwestern part of the former tank battery. The discharge exits
the bermed tank area through a drainage pipe .which leads to the
site access road drainage ditch. The salt water pond overflow
proceeds westward along the south road ditch unless the discharge
exceeds the capacity of the ditch in which case, some of the flow
runs over the access road to the north road ditch and progresses
westward along with the flow in the south road ditch. .
REGIONAL GEOLOGY
The site is located within unconsolidated sediments of the
Atlantic-Gulf Coastal Plain physiographic province. These
sediments are of Pleistocene age and were deposited by the
ancestral Mississippi River that derived sediment and flow from the
central part of the North American continent. The sediments were
deposited in a complex series of alternating beds of sand, gravel,
silt and clay. The beds dip toward the south and southeast and
vary in thickness from less than 100 ft. in southwestern Louisiana
to more than 7,000 ft. beneath the Gulf of Mexico.
L.
The surficial topsoil generally ranges from 0-2 ft. below the
ground surface and consists of dark brown organic clay with some
black fairway-manganese nodules and iron staining. Below the
surficial soils is a brown and gray mottled clay. This clay zone
extends to depths ranging from 19-23. ft below the CJround surface
for mo.st of the site. This zone lessens to 13-14 ft. below CJround
surface to the west of the site. Black fairway-manganese nodules
and iron staining were noted throughout this clay unit. Next,
extending to depths of 22-25 ft. below CJround surface for the
majority of the site, was a brown and gray sandy silt and silty
clay unit. This zone extends to only 16-17 ft. below ground
surface to the west of the site. The deepest unit encountered
beneath the site, according to the ESI, is a reddish brown to
grayish brown sand extending to depths of at least 110 ft. below
ground surface. This sand unit coarsened downward from fine to
medium sized sand to some fine and coarse gravel. Banded iron
staining was also reported observed in this zone.
The cross-sections and boring logs reveal basically three
subsurface stratigraphic units: an upPer clay unit, a middle
clay/silt/sand unit and a lower sand/gravel unit. The middle unit
appears to act as a transition unit between the upper clay and
lower sand.
REGIONAL HYDROGEOLOGY
The major hydrogeologic unit in the site vicinity is the Chicot
Aquifer System. The Chicot Aquifer System is subdivided into the
Upper and the Lower Cbicot Aquifers. Locally, the Upper Chicot
Aquifer is further divided into the Abbeville unit and the Upper
Sand unit.
-------
The Chicot Aquifer System generally consists of a coarsening
downward sequence of clays, silts, sands, and qravels. The medium-
to coarse-qrained sand and qravel aquifer units dip and thicken
southward toward the Gulf of Mexico. Water levels in the Chicot
Aquifer range from near land surface to 150 ft. below land surface.
Water levels are lowest in areas of heavy industry and significant
population.
Water levels in 1903 showed a natural southward qradient that
probably existed before heavy qround water development began. Rain
falling on areas of recharge for the Chicot Aquifer System provided
baseflow to the Sabine, Vermilion and Atchafalaya Rivers during
pre-development years. The southward water level qradients of the
early 1900s have been reversed as of approximately 1940 and now
slope northward toward large pumping centera (such as the city of
Lafayette, Louisiana, located approximately 15 miles north of the
site).
Ground water beneath the site was encountered at approximately 30
ft. below the qround surface (-10.0 feet, MSL) in the upper Chicot
Aquifer system, Abbeville unit. The qround water flow direction
under the site was found to be generally west-northwest with a
qradient of 0.0002 ft/ft. Both of these observations of the local
qround water flow are consistent with regional flow conditions.
In accordance with EPA's Guidelines for Ground Water Classification
under the EPA Ground Water Protection Strateav. (December 19861,
the qround water beneath the site is classified as a Class II
qround water because the qround water ia currently used or is
potentially available for drinking water or other beneficial uses.
Ground water in the area is used for drinking water purposes (there
are more than 55 residential wells within 1/2 .ile of the site and
three city of Abbeville municipal wells within 3 miles of the site)
as well as for aqricultural purposes (irrigation and crawfish
ponds).
KNOWN OR SUSPECTED SOURCES OF CONTAMINATION
It is believed that most, if not all of the contamination found at
the site is related to the waste disposal activities that occurred
in the late 1970's and early 1980's. The facility received wastes
related to the exploration and production (-E&P-) or oil and gas
from throughout the Gulf Coast Region, including offshore
operations. These wastes were mainly drilling muds, drilling
fluids, produced water and other associated wastes such as workover
fluids and tank bottoms. Almost all of the contaminants found at
the site can be related to one or more of these waste types.
It is believed that most of the remaining contaminants identified
during site investigations that can not be directly related to the
oil and gas E&P disposal activities are either a result of off-site
-------
human activities (pesticides resulting from local agricultural use)
or naturally occurring (arsenic in the ground water). Evidence
also exists to support the prior occurrence of a. limited amount of
illegal dumping of unknown wastes at the facility.
The wastes were delivered to the site by vacuum tank trucks which
were ordered to dispose the material into the appropriate pit based
on a physical description of the waste given by the driver to the
operator. Drilling muds were transferred into either the northwest
or northeast pit. Lighter '-Tastes such as produced water were
sometimes dumped directly into the large, salt water pond located
to the west of the disposal pits.
CONTAMINATION CHARACTERIZATION
The media and associated contaminants of concern at the site were
identified in the RI. Not all contaminants of concern are
contaminants that drive the risk or the need to conduct remedial
actions at the site. The contaminants most critical to risk are
discussed in detail in section VI., StJMKARY OF SITE RISKS. Based
on the results of the RI, the following media categories were
identified:
.

Sludges and Associated Soils
Sediments and Surface Soils
Surface Water
Ground Water
Sludaes and Associated
Soils:
The three waste disposal pits as shown on Figure #2 (northwest pit,
northeast pit and south pit) contain the majority of contamination
found at the site. There was no liquid found in the northwest pit,
but the probing revealed an average sludge depth of approximately
16 ft. Natural clay is present under the sludge at 16 ft. The
estimated sludge volume of the northwest pit is 9,200 cubic yards
("yd3"). The majority of the northeast pit contains liquid down to
approximately 7.5-8 ft, which i8 underlain by about 7-7.5 ft. of
sludge. A clay bottom was reached at 15 ft. below the water
surface. The estimated volume of liquid in the northeast pit is
1,300,000 gallons with an estimated sludge volume of 5,400 yd~.
The northeast pit also contains a paraffin layer of scum which
floats on the water surface at thicknesses up to 3 inches. The
south pit contains primarily liquid with depths ranging from 9-14
ft. The thickness of the sludge on the bottom of the pit varies
from 6 inches to 2 ft. The estimated volume of liquid in the south
pit is 1,300,000 gallons with an estimated sludge volume of 900
yd3.
The sludge from the northwest and northeast disposal pits are
similar in appearance, being described as a brown to gray/black
sludge with a noticeable petroleum odor. The south pit sludge also
-------
has a noticeable petroleum odor, but its appearance is described to
be a soupier and blacker material than that of the other two pits.
The clay/soil underlying the pits typically has a hydrocarbon odor
which varies from slight to strong. Some of the upper clay/soil
samples has a visible dark, oily liquid in the pore spaces.
Numerous volatile and semi-volatile organic compounds, typical of
petroleum type constituents, were detected in the sludge samples
from the three disposal pits. The following compounds were the
predominant organic contaminants detected in the pit sludges. The
values presented are the greatest concentration detected in each
pit.

Sludge samples from each of the three waste pits were also analyzed
for pesticides and polychlorinated biphenyls (WPCBsW). Sludge
samples from the northwest pit and the northeast pit were found to
contain low concentrations of several pesticides. One type of PCB,
Aroclor-1260, was found to be present in two sludge samples
collected from the northeast pit.
Sludge samples from each of the three pits were evaluateci for
chloride concentrations, total petroleum hydrocarbons (wTPHW) and
pH. The sludge samples were found to have varying levels of each
parameter. The south pit sludge reported the hiqhest concentration
of chloride at 66,900 mg/kg while the northeast pit recorded the
highest TPH at 823,000 mg/kg (82.3'). The pH of the sludge ranged
from 7.1 to 12.0.
-------
Various dioxin isomers and one furan isomer were detected in the
sludge samples collected from the three waste pits. Dioxin and
furan isomers are evaluated according to a toxicity equivalence
factor which relates the toxicity of each isomer to that of
2,3,7,8-tetrachlorodibenzo-p-dioxin ("TCDD"), which is the most
toxic of the dioxin/furan isomers. A total of six sludge samples
reported toxici ty equivalence to 2,3,7, 8-TCDD above o. 01. ~g /kg,
however, no sample had an equivalence greater than or equal to 1.00
~g/kg. 1.00 1£9/kg is the current cleanup standard for residential
scenarios established in response to a Center for Disease Control
risk assessment that established this as a "level of concern".
Numerous inorganic compounds (metals) were detected in the sludge
samples from the three disposal pits at concentrations which
exceeded background soil levels. The following metals, proceeded
by their greatest detected level within each pit, were the
predominant inorganic contaminants detected in the pit sludges:

The clay soils beneath the pits and the floating paraffin layer
("scum") on the northeast pit were found to contain many of the
same compounds that were detected in the waste pit sludqes,
especially the organics, although at lesser concentrations.
Besides the underlyinq clay soils and floatinq paraffin layer,
soils associated with the sludges in the disposal pits for purposes
of this discussion includes the pit berms, sediments from the ponds
and drainage ditches, and surface soils affected by past
operations.
-------
Pit Berms
Durinq the
encompasses
very sound.
spillage or
field investigation, the outer pit berm, which
the three disposal pits, was evaluated and appeared
There was no visual evidence of present seepage, past
overflows.
Both the organic and inorqanic analyses reflected relatively
uncontaminated material in the circumferential berm except on the
inside of the berm at the northwest corner of the northwest pit,
where there appeared to be some residual sludge or other petroleum
product present. This location revealed semi-volatile tentatively
identified compounds ("TICs") and TPBs as well as numerous
inorqanic compounds such as barium, cadmium, calcium, chromium,
lead, mercury and zinc at levels above background soil
concentrations. The levels at which these contaminants were
present were significantly lower than the concentrations detected
in the pit sludges, however, the concentrations present indicate an
impact from site activities.
Sediments
The canal sediment samples indicated low leve1.s of several organic
compounds such as 4-methyl-2-pentanone, benzoic acid and
benzo (a) pyrene. There were no detectab1.e 1.eve1.s of tarqet compound
list ("TCL") pesticides or PCBs found in the cana1. sediment
samples. The only inorganic parameter detected in the sediment
samples, which was outstanding compared to background va1.ues, was
mercury detected at 0.20 mq/kq.
The majority of contamination detected in the sa1.t water ponds'
sediments occurred in samples located in the southeast corner of
the sa1.t water pond at or near the suspected discharqe pipe from
the south pit. At this discharge pipe, the sediment was oily and
black in color and had a distinct petroleum odor.
The only non-laboratory suspected vo1.atile organic contamination
appeared in t..he form of TICs. on the other hand, many semi.-
volatile org~~ic compounds were detected. Most of the compounds
detected werei polycyclic aromatic hydrocarbons (WPABaW). The
highest concer.ltrations reported were for 2-methylnaphthalene (5,670
JJg/kq), phenanthrene (2,750 JJq/kq) and fluorene (1,070 ~q/kq).
Elevated leve,ls of naphthalene, pyrene and chrysene were a1.so
detected alon~J with a larqe numher' of semi-volatile TICs.
No pesticides or PCBs were detected in the pond sediments. The
dioxin and fw:'an analysis reported that there was no 2,3,7, S-TCDD
detected. Twc) different dioxin isomers were detected in seven of
the nine samples analyzed, however, due to the low values and the
lower relati v,e toxicities of the isomers detected, none of the
samples had a toxicity equivalence to 2,3,7,S-TCDD greater than
0.01 p.g/kg.
-------
The most significantly elevated inorganic parameter detected in the
pond sediments was barium. Elevated barium levels were detected
throughout the pond sediments. The highest. value recorded was
9,860 mg/kg barium detected in a sediment sample collected from the
southeast corner of the salt water pond. The southeast corner also
reported elevated levels of calcium, chromium, cobalt and zinc.
In ;eneral, the concentration of barium and chloride in the site
dra~nage ditch sediments are the highest near the outfall/overflow
from the salt water pond and decrease as the ditch proceeds to the
weSl: toward U.S. Route 167. The highest detected barium and
chloride concentrations were 4,030 and 1,257 mg/kg, respectively.
The surface water concentrations of barium, calcium, chloride and
sodium were also detected at higher values in the drainage ditches
on-site than they were in the off-site U.s. Route 167 ditch,
immediately after the confluence of the site runoff.
Surface Soils
The majority of the contamination detected in the on-site soils
occurred in the former tank battery area soils. There were,
however, some elevated values, primarily inorganic constituents,
detected in the pond island/mound soils and the soil borings
adjacent to the disposal pits. The most siqnificantly elevated
parameters, compared to background, were arsenic, barium,
beryllium, calcium, chloride, cobalt, lead, mercury and nickel.
The organic compounds detected in the visua1.ly stained tank battery
area soils revealed hydrocarbon contamination. The only volatile
organic compounds detected, other than TICS, were ethyJbenzene and
total xylenes. Various semi-volatile organics, however, were
detected. These were primarily PABa which included phenanthrene,
fluoranthene and fluoranthene isomers, pYrene and chrysene. A
large number of semi-volatile TICs were also detected in the tank
soils.
L,
No pesticides or PCBs were detected in any of the off-site soils.
Several pesticides were detected on-site at low concentrations.
TPH values for the tank soils were found to be elevated above
background levels. The TPB values were found to generally decrease
with depth. The highest reported TPB value was found in a surface
sample at 18,110 mg/kg. Chloride concentrations, although not
significantly elevated above background, were found to increase
with depth rather than decrease. This is possibly due to the
relatively high sOlubility of chloride compounds.
The dioxin and furan analysis performed on the tank soils revealed
the presence of some dioxins.; 2,3,7, 8-TCDD, however, was not
detected nor were any furans. A total of four dioxin isomers were
detected nine times in the eleven samples analyzed. Two samples
reported toxici ty equivalence to 2,3,7, 8-TCDD greater than 0.01
13
-------
Jl.g/kg, however, no tank soil sample had an equivalence greater than
or equal to 1.00 Jl.g/kg.
The concentrations of inorganic compounds (metals) in the tank
soils were evaluated against background soil levels to determine
whether the tank soil concentrations of these compounds were
elevated. The predominant inorganic compounds which were found to
be elevated in the tank soils were arsenic, barium, calcium,
chromium, lead, magnesium, nickel, potassium, silver, sodium and
zinc.
Surface Waters
The disposal pit liquids (waters) were studied by cOllecting a
surface and a subsurface composite water sample from both the
northeast and south pits. Both the organic and inorganic analyses
for the pit waters reflected elevated values compared to the off-
site ditch and canal waters and the on-site ditch and salt water
pond waters.
The predominant volatile organic contaminants detected in the pit
waters were common fuel constituents. Benzene, ethylbenzene,
toluene and total xylenes ("BTEX") were detected at maximum levels
of 200, 56, 78 and 190 Jl.g/l. The solvents 1,1-dichloroethane and
tetrachloroethene and a relatively high value of acetone were also
detected.
The semi-volatile organic analysis revealed the presence of several
methylphenol isomers and various PABa such as naphthalene, 2-
methylnaphthalene, fluorene, phenanthrene and chrysene. Various
semi-volatile TICs were also detected such as substituted benzenes,
phenols and naphthalenes.
Total organic carbon ("'l'OC") and chemical oxygen demand ("COD")
were reported at substantially higher values in the disposal pit
waters than those reported for the site ditches and salt water
ponds. The highest TOC and COD values were 258 and 1,200 mg/l,
respectively.
The pesticide/PCBs analysis performed on the pit waters detected
various pesticides at low concentrations.
The inorganic sample results from the pit waters detected antimony,
barium, beryllium and chromium at levels of 93.3, 13,000, 2.5 B and
99.7 Jl.g/l, respectively. As a reference, the KCL for antimony is
currently being proposed at 10 or 5 Jl.g/l while the MCLs for barium,
beryllium and chromium are currently 2,000, 1.0 and 100 Jl.g/l,
respectively. Many other inorganic parameters, including arsenic,
copper, zinc and chloride were detected at levels which were
elevated compared to other site waters.
-------
In addition to the surface waters in the disposal pits, the PAS oil
site contains surface water in the salt water pond (or large pond),
the northwest pond and an abandoned canal at' the eastern edge of
the property. The majority of precipitation runoff from the site,
including overflow from the ponds and the pits, drains to the west
in the ditches on both sides of the site access road. Flow
continues along the road to the U.S. Route 167 drainage ditch.
During the investigation, the surface waters and sediments were
investigated to evaluate the past and current migration of
contamination.
The salt water pond has overall dimensions of approximately 765 ft
by 430 ft with an average liquid depth of 2 ft. A deeper area was
discovered in the northeast corner measuring 95 ft by 125 ft and
having an overall depth (water and sediment) near 7.5 ft. The
total volume of water within the salt water pond is approximately
4,500,000 gallons.
The northwest pond measures approximately 165 ft by 175 ft with
varying det>ths from 2 ft to 11 ft. The water volume in the pond
was calculated to be approximately 800,000 gallons.
The canal is no longer utilized and i. dead-ended at several
locations in the area of the site. Water, therefore, currently
does not flow and the water level present in the canal is solely
dependent on local rainfall. The water in the canal segment
adjacent to the site has been observed to be nonexistent as well as
over 3 ft in depth depending on the time of year.
Water samples collected from the canal showed no evidence of
organic or inorganic contamination.
There were no volatile organic compounds detected in the pond water
samples which were not suspected to be attributable to laboratory
contamination. The only TCL saLi-volatile organic compound
reported was one PAIl at a low concentration. There were, however,
numerous semi-volatile TICs detected.
t..
Various pesticides were detected at very low concentrations in the
pond water samples. There were no PCBs detected.
The highest TOC, COD and TPH values detected in the pond waters
were 30.5, 86 and 1.25 mgll, respectively.
Several inorganic elements were detected in the pond water samples
at elevated levels compared to off-site ditch samples and canal
samples. The highest concentrations of barium and chromium were
detected at 2,890 and 34.8 ~g/l, respectively. calcium, sodium and
chloride were also reported at elevated values. Filtered (passing
0.45 micron) samples were also collected and they revealed a
significant decrease in the concentration of many metals. Analysis
of filtered samples gives an indication of the portion of
-------
..-
contaminant that is in the water column versus the portion that is
attached to suspended solids (greater than 0.45 microns in size)
that can be filtered out of the water sample. The filtered results
showed a 47% reduction in the barium level, down to 1,380 p.'l/l, and
the chromium level was reduced to 9 . 1 p.'l 11. Al thou'lh not
considered elevated in the unfiltered sample, the levels of
aluminum, iron, lead, maqnesium, man'lanese and potassium also
showed a decrease in concentration in the filtered sample. The
calcium and sodium levels, however, showed no filtered reduction.
Ground Water
Ground water beneath the site was encountered at approximately 30
ft. below the ground surface in the upper Chicot Aquifer System,
Abbeville Unit. The ground water flow direction under the site was
found to be 'lenerally west-northwest with a gradient of 0.0002
ft/ft. Both of these observations of the local ground water flow
are consistent with re'lional flow conditions.
There were no siqnificant, positively identified contaminant trends
resultin'l from the analytical results of the ground water samples
obtained primarily from wells screened at 30' to 40'. There were,
however, some contaminants present at elevated levels at individual
locations. The elevated constituents were primarily metals
(barium, chloride, chromium, lead, nickel, etc.).
The only siqnificant orqanic compound detected was benzene, however
it was detected in only 2 samples out of the 34 ground water
samples collected. It was reported in HW-5 and MW-7 at values of
3 and 2 p.'l/l, respectively, which is less than its maximum
contaminant level ("MCL") standard of 5 p.'l/l. Seven pesticides
were detected at trace amounts durin'l Phase 2 of the la, but none
of these were detected durinq Phase 1.
The total metals analysis reported chromium and lead at levels
hi'lher than their current drinkin'l water standards. Chromium was
reported at its hi'lhest concentration of 1,330 p.'l/l, which is well
above its MCL of 100 p.q/l and lead was reported at its highest
concentration of 141 p.q/l, which is above the promulqated "action
level" of 15 p.'l/l. Antimony, beryllium and nickel were also
detected above newly promulgated MCL values.
Obvious differences in the concentrations of metals existed between
the total and dissolved (filtered) ground water samples. The
filtered chromium and lead concentrations were at or below 12.6 and
1.0 p.'l/l, respectively. Nickel, on the other hand, maintained its
hi'lh, elevated total metals concentrations in the filtered samples
as well. Nickel's maximum values were reported at 659 p.'l/l in its
total and 317 p.'l/l in its filtered analyses. Other constituents,
considered to be elevated in the total metals analysis, such as
aluminum, antimony, barium, beryllium and chloride, had their
concentrations dramatically reduced when the samples were filtered.
-------
An off-site, upgradient background monitoring well, MW-10, revealed
high concentrations of numerous metals. The maximum values
reported in any of the site monitoring wells for barium and lead
were detected in this well. Other metals detected at high levels
in the background well include aluminum, chromium and zinc.
The residential water supply wells (ten total, ranging in depths
from 90' to 200') sampled during the RI apparently have not been
impacted by contaminants from the PAB oil site. These residential
wells did not show evidence of elevated concentrations of any
target compound or analyte that could be directly related to the
site.
The most noticeable results from the residential water analyses
were the arsenic results. Arsenic was detected in every
residential well at concentrations up to 30.5 ~9/l (arsenic MCL is
50 ~g/l). The source of these elevated values remains unknown. :It
is evident that they are not related to past operations at the
site. The site's highest level of arsenic was 10.7 ~g/l.
Additionally, the two residential wells reporting the highest
values are located south-southwest of the site, which is not in a
downgradient position.
EXPOSURE ROUTES
Three potential contaminant migration routes were identified at the
PAB oi1 site; air, surface water and ground water. The air pathway
for contaminant migration is believed to be inapplicable at the PAS
Oil site. Based on information obtained from the ESX and during
the RI, there appears to be no significant levels of contaminants
in the air. Xn addition, air monitoring data during excavations at
a nearby superfund site, Gulf Coast Vacuum, on wastes similar to
those found at the PAS oil site, did not reveal significant air
emissions.
L
The surface water pathway is considered to be a potential route of
contaminant migration. Several site-related contaminants appear to
be migrating off-site via the site's surface water drainage system.
:It is believed that all overflow/excess water from the disposal
pits and ponds and the majority of site surface runoff exit the
site, heading west, through the drainage ditches adjacent to the
site access road.
The ground water pathway is considered to be a potential route of
contaminant migration. Although there were not positively
identif ied contaminant trends in this Class XX ground water, there
were some compounds andlor elements which have been observed to be
present at elevated levels at various locations. The elevated
constituents were primarily metals (barium, chloride, chromium,
lead, nickel, etc.) with the exception of a few detects of benzene
and chloroform.
17
-------
The largest potential impact on the integrity of the ground water
under the site will most likely result. from potential
leachate/infiltration migrating from the disposal pits, while
lesser impacts could potentially occur from surficially
contaminated soils such as those found in the former tank battery
area.
There are several residents located just west of the site, between
the site boundary and Route 167. There are other residences
located both north and south along Route 167, and along Parish Road
P-3-26, which passes about 1/4 mile southeast of the site. There
are no permanent dwellings north of the site, although there is one
resident who lives in a trailer near the southwest corner of the
sand quarry. These nearby residents might be exposed to site
contaminants by using ground water from residential wells or they
could be exposed to surface water and sediments in the drainage
ditches. The closest major population center, with about 3,500
residents, is the city of Abbeville, located about 3 miles south of
the site.
Under current site conditions, there are no people who live or work
on-site. Therefore, a trespasser is most representative of the
population most likely to be exposed on-site under current
condi tions. Potential exposure would be frOJI direct contact,
ingestion, and inhalation of site contaainants.
In the future, it is possible the site might be developed for
residential, agricultural or industrial usa. As the site currently
exists, development for agricultural usea with possible on-site
residence by farmers is considered most likely, since the
surrounding land is primarily used for pasture land and residences.
VI.
SUJDDRY 01' S%TB IUsa
A baseline risk assessment ("BRA") was conducted to analyze the
potential adverse health effects (both current and future)
resulting from human exposure to hazardous substances in surface
soil, sludge, sediment, ground water and surface water at the PAB
oil site. The BRA provides the basis for taking action and
indicates the exposure pathways that neecl to be addressed by the
remedial action. It serves as the baseline indicating what risks
could exist if no action were taken at the site. This section of
the ROD reports the results of the BRA conducted for this site.
By definition, a BRA evaluates risk under the no-action alternative
(that is, in the absence of any remedial actions to control or
mitigate releases or exposures). The BRA for this site was
prepared utilizing data from the RI. The methods used in the
development of the risk assessment are based on general EPA
quidance (Office of EmerGencv and Remedial ReSDonse. Risk
Assessment Guidance for SUDerfund. Vol. I. Human Health
Evaluation Manual (Part A1. 1989. also known as "RAGS"), the NCP,
-------
and in accordance with site-specific guidance developed by Region
VI. In addition, an environmental risk assessment was conducted to
evaluate risks to environmental species. These reports can be
found in the Administrative Record.
CHEMICALS OF POTENTIAL CONCERN
Analytical data from sludge, soil, ground water, surface water and
sediments were evaluated to identify chemicals of potential concern
at this site. Any chemical detected in any sample was considered
to be a possible chemical of concern. Chemicals were eliminated
from consideration if they are essential nutrients and are nontoxic
at the levels encountered on site or if they were infrequently
detected. Seventy-five chemicals selected as contaminants of
potential concern are listed in Table #1.
An exposure point concentration (used for risk calculations) is the
arithmetic mean concentration of a chemical in a medium, averaged
over the area in which exposure is expected to occur. Because of
the uncertainty associated with the exposure point concentrations,
the upper 95th confidence limit of the arithmetic mean (UCL95) is
generally used to provide a degree of conservatism. If the
calculated value of the UCL95 exceeded the maximum value used to
calculate the UCL95 at an exposure point, then the maximum value
(rather than the UCL95) was used. Chemicals which were analyzed
for but not detected in a sample at a level higher than the normal
detection limi t were labeled as -undetected-. For purposes of
calculating exposure point concentrations, if a chemical was
detected at least once in a medium, the chemical was assumed to be
present in all samples of that medium, and non-detects were
evaluated using one-half the -undetected- value. The resulting
exposure point concentration values used in the PAD oil risk
assessment are presented in Table #2.
EXPOSURE SCENARIOS EVALUATED
The purpose of the exposure assessment was to identify and evaluate
the mechanisms by which people might be exposed to the chemicals of
concern at the PAD Oil site. Based on a review of site conditions
including land use, contamination patterns and human activity
patterns, the populations most likely to be exposed are:
current on-site trespassers.
current off-site residents (adults and children).
Future on-site resident farmers (adults and children).
The most important exposure pathways are judged to be:
Ingestion of and dermal contact with contaminated surface
soil, sludge and sediments.
-------
Ingestion of homegrown vegetab~es, beef and mi1k raised in
contaminated soil or sludge. .
Ingestion of ground water, along with dermal contact with
water (while bathing) and inhalation exposure to VOCs released
from ground water to indoor air.
Dermal exposure to surface water in pits, ponds, marshes and
ditches.
The exposure scenarios quantified in this risk assessment are
summarized in Table #3.
The magnitude of human exposures to the chemicals of concern at the
PAS oil site is described as the potential dose or intakes by each
receptor. In general, standard exposure factors, as defined in the
Human Health Evaluation Manual. Sunnlemental Guidance: Standard
Default Exnosure Factors (OSWER Directive 9285.6-03\, were used for
this determination. In addition, variability among individuals
usually leads to a wide distribution of intake values. In most
cases, input variables in the risk equation were chosen so that the
resulting intake is about equal to the 95th percentile of the dose
distribution curve. This is referred to a8 the Reasonable MaximuJR
Exposure (-Rlm-) . For future residential popu~ations, the
variables were also chosen to estimate the average (-AVG-) intake
(about the 50th percentile of the distribution). This approach,
commonly referred as the -central tendency-, provides a range of
risk estimates, AVG to RME, for future residential exposures. The
key assumptions used to calculate the AVG and RIlE intake factors
and the actual calculated values are presented in Tables #4 and #5
respectively.
TOXICITY ASSESSMENT
The purpose of the toxicity assessment was to weigh availab~e
evidence regarding the potentia~ for contaminants to cause adverse
effects in exposed individuals. The toxicity assessment involved
two steps: hazard identification and dose-response assessment. The
hazard identification determined whether exposure to a chemical
could cause an increase in the incidence of a particular adverse
health effect (carcinoqenic or non-carcinoqenic) and whether an
adverse health effect would likely occur in humans. The second
step, dose-response assessment, quantitatively eva~uated the
toxicity information and characterized the relationship between the
dose of the chemical received and the incidence of adverse health
effects in the exposed population.
Toxici ty values (.1.a..L.., reference doses for non-carcinogens and
slope factors for carcinogens) are used in the risk
characterization to estimate the likelihood. of adverse effects
occurring in humans at different exposure levels and are specific
to exposure routes. The EPA has established a weight-of-evidence
classification system for carcinogens as follows:
-------
*
*
Group A - Human carcinogen
Group B1 or B2 - Probable human carcinoqen; B1 indicates that
limited data are available and B2 indicates sufficient
evidence in animals and inadequate or no evidence in humans
Group C - Possible human carcinogen
Group D - Not classifiable as to human carcinoqenicity
Group E - Evidence of non-carcinogenicity for humans
*
*
*
Slope factors ("SFs") have been developed by EPA's Carcinoqenic
Assessment Group for estimating excess lifetime cancer risks
associated with exposure to potentially carcinogenic contaJU.nant(s)
of concern. SFs, which are expressed in units of (mg/kg-day).1, are
mUltiplied by the estimated intake of a potential carcinogen, in
mg I kg-day , to provide an upper-bound estimate of the axcess
lifetime cancer risk associated with exposure at that intake level.
The term "upper bound", reflects the conservative estimate of the
risks calculated from the SF. Use of this approach makes
underestimation of the actual cancer risk highly unlikely. SP. are
derived from the results of human epidemioloqical studies or
chronic animal bioassays to which animal-to-human extrapolation and
uncertainty factors have been applied (.!L.S.£., to account for the use
of animal data to predict effects on humans).
Reference doses ("RfDs") have been developed by EPA for indicating
the potential for adverse health effects from exposure to
contaminant(s) of concern exhibiting non-carcinoqenic effects.
RfDs, which are expressed in units of mg/kg-day, are estimates of
lifetime daily exposure levels for humans, including sensitive
individuals. Estimated intakes of contaminant(s) of concern from
environmental media (JLJL.., the amount of a contaminant (s) of
concern ingested from contaminated drinking water) can be prepared
to the RfD. RfDs are derived from human. epidemiological studies or
animal studies to which uncertainty factors have been applied
(JL,£L., to account for the use of animal data to predict effects on
humans) .

cancer effects and lists available RfD values and confidence

RISK CHARACTERIZATION
Human Health Risks
cancer aiaka
The risk of cancer from exposure to a chemical is described in
terms of the probability that an individual exposed for his or her
-------
lifetime will develop cancer. Typically, cancer risks of lX10.e
(one in a million) or lower are considered to be so small that they
are of no practical concern. Higher cancer risk levels may be
cause for concern, and EPA typically requires site remediation if
risks exceed lxlO-4. Estimated cancer risks from exposures to the
chemicals of potential concern at PAS oil are summarized in Table
#8.
Cancer risk for current trespassers, mainly fro. exposure to sludge
and surface water in the Northeast Pit and South Pit, is estimated
to be about 2XIO-4. The main contributors to this risk are the
carcinogenic PABs, PCBs, beryllium and pesticides.
Cancer risk to current off-site residents associated with exposure
to sediment and surface water is about. lXlO-5. This risk is
predominantly due to beryllium in the surface water. Excess cancer
risk to hypothetical future on-site residents in the Pit area is
estimated to be 9XIO-4. This risk is contributed 8I1inly bl exposure
to PABs in soil, primarily via food chain intake (3x10.), and by
arsenic and beryllium in the ground water (5X10.4). If the
Northwest and Northeast Pits were excavated and the sludge spread
on the land surface, the excess cancer risk to residents would be
significantly higher (2X10.2). This risk is attributable mainly to
direct contact and food chain exposure to PCBs, PABa and dioxins.
These risks to residents are associated with exposures in and about
the area of their home and yard. Assuming that older children
(above 7 years old) and adults leave their yard area and are also
exposed at pits, ponds, marshes and ditches located on site, the
total cancer risk may be approximated by 8u1II1II-I1\9 the risk to
residents in their yard and home (9X10.4) and the risk to
trespassers (2XIO.4). If residents are exposed at pita, ponds,
marshes and ditches more frequently than was assumed for
trespassers (60 days per year), the excess risk would be
proportionately higher.
BODCaDOer aisa
Evaluation of noncarcinogenic risk is accomplished by comparinq a
calculated intake with an acceptable intake for each chemical and
for each pathway that contributes to a population's exposure. The
ratio of the calculated intake versus the acceptable intake is
termed the Hazard Index (HI). Hazard Indices calculated for all
the exposure scenarios quantified at PAS oil are summarized in
Table #9. An HI of 1.0 or more shows an intake greater than the
acceptable level and indicates the need for remedial action.
,
"
Noncancer risks do not appear to be of concern for current off-site
-------
residents. current on-site trespassers may have increased risk of
noncancer effects due mainly to dermal exposure to pesticides in
the South Pit. For hypothetical future on-site residents, hazard
index values for the primary contributors are estimated to be 10
for adults and 20 for children under current site conditions. This
risk is due primarily to arsenic, antimony, chromium, nickel and
vanadium in the drinking. water, with lower but sometimes
siqnificant contribution from barium in soil. If the sludqe from
the pits was spread on the land surface, noncancer risks to adults
and children would be 20 and 30, respectively. This additional
risk is associated mainly with organics (di-n-octylphthalate,
acetone, PABs) which tend to accumulate in the food chain, with a
siqnificant contribution from barium in sludge as well.
The likely effect of exposures to lead from site contamination were
estimated using EPA' s Uptake/Biokinetic model. using the qeometric
mean of lead concentrations in the sludqe pits (239 mq/kq), blood
lead levels are predicted to averaqe 1.8 p.q/dL for children exposed
at the pit area, with very low probability that any levels would
exceed 10 p.q/dL. If sludqe were excavated from the Northwest and
Northeast Pits, the blood lead levels of exposed children would
averaqe 3.5 p.q/dL, with only a 0.1' chance that an individual would
exceed 10 p.q/dL. This indicates that lead exposure from either
surface soil or sludge is not of major concern.
Uncertainties Associated With The Human Health Risk Calculation
There are a number of staqes in the risk assessment process where
precise evaluations are not possible. These include uncertainties
reqardinq the true concentrations of chemicals in environmental
media, the amount of contaminants taken in by humans and the likely
health consequences of the resultinq exposure. In particular, the
followinq items are sources of uncertainty in this risk assessment.
Co.
- Likely to Underestimate Risk
Lack of toxicity data for numerous chemicals (e.q., TICs).
Inability to quantify some pathways (e.g., dermal contact with
PABs, dermal contact with metals in soil, uptake of metals
into the food chain).
- Likely to overestimate Risk
Use of conservative human exposure assumptions.
Use of conservative toxicity values.
Miqht Either Overestimate or Underestimate Risk
Evaluation of nondetects usinq one-half the detection limit
-------
(this is especially important for chemicals with a high
frequency of nondetects, such as PAHs, beryllium and
pesticides).
Use of simple models to predict uptake of organics into the
food chain.
As noted, some of these limitations may lead to an underestimate of
risk, some are more likely to overestimate than underestimate risk
and some introduce uncertainty that may either overestimate or
underestimate risk. Consequently, the quantitative risk estimates
derived for this site should be considered approximate, with a
significant range of uncertainty.
Environmental Assessment
A screening-level environmental assessment was performed for the
PAB Oil site. No rare, threatened or endangered species are
associated with the site and nearby areas. Local species of
wildlife of minor recreational importance and migratory waterfowl
are the only ecological resources ot potential significance
associated with this site. No jurisdictional wetlands are present
on the site or in nearby areas. Nearby surface water bodies
(ditches and canals) are semi-permanent and are unlikely to support
regionally significant aquatic communities.
Areas, contaminants and potentially exposed populations of concern
are as follows:
.
Aquatic life exposed to iron in surface water in the salt
water pond and southeast marsh area.
Aquatic life exposed to chromium, lead and manganese in
sediment in the salt water pond and lead and mercury in the
off-site ditch.
Rabbits inqestinq vegetation contaminated with barium from
soil in the southeast marsh area.
Higher trophic level organisms that may feed on rabbits in the
southeast marsh area are unlikely to experience adverse effects
from exposure to barium. Migratory waterfowl are unlikely to be
exposed to the relatively low toxicity of chemicals present in the
two larger water bodies on site (salt water pond and northwest
pond) for sufficient time to experience a dose potentially
associated with adverse effeeta.
Based on the data collected during the R:I and BRA, actual or
threatened releases of hazardous substances from this site, it not
addressed by implementinq the response action selected in this ROD,
may present an imminent and substantial endanqerment to public
health, welfare, or the environment.

REMEDIAL ACTIOJ{ OBJECTIVES
The remedial action objectives ("RAO") consist of media-specific
goals for protecting human health and the environment and specify:
The contaminant(s) of concern,
Exposure route(s) and receptor(s) and
An acceptable contaminant level.
The medium-spec if ic chemical concentrations that are protective of
human health and the environment are ~ermed the remediation qoals.
The remediation qoals, accordinq to 40 cn 300.430 (e) (2) (i) "shall
establish acceptable exposure levels that. are protective of human
health and the environment". The followinq requirements must be
considered during the development of the remediation goals:
Applicable or relevant and appropriate requirementa ("ARARs")
related to:
acceptable exposure levels for systemic toxicants,
acceptable exposure levels for carcinoqens,
technical limitations and
uncertainty factors.
Maximum Contaminant Level Goals (MCLGs) established under the
Safe Drinkinq Water Act that are set .at levels above zero.
Maximum Contaminant Level (HCLs) when the HCLGs are set at
zero or are not relevant and appropriate.
When the attainment of chemical-specific ARARs will result in
a cumulative risk in excess of 1X10-4.
Water quality criteria established under the Clean Water Act.
Alternate concentration limits ("ACLs") may be established in
accordance with CERCLA Section 121(d) (2) (B) (ii).
Sensitive habitats of species protected under the EndanqE7ed
Species Act.
In the followinq sections, the RAOs for each media at the site are
discussed. The remediation qoals are then set, expressed in terms
of the chemical of concern, exposure routes, potential receptors,'
ARARs and allowable exposure levels.
surface Water
The RAOs for the site surface waters are to prevent oral and dermal
exposure to both humans and environmental species and to mitiqate
the miqration of contaminants via surface runoff or throuqh
infiltration to the qround water. A secondary objective is to
-------
remove the water from the pits and ponds in order to effectively
remediate the underlying sludge/sediment.
The contaminants of human health concern in the site surface waters
are beryllium, barium, benzene and toluene. These limits are to be
utilized as the remedial goals for the treatment and release of
this media. Beryllium was identified in the BRA as the main
contributor to a human health risk (via dermal exposure under the
current trespasser and off-site residential land use scenarios)
from the site surface water. This risk resulted from the detection
of beryllium in only one of 18 samples. The single value detected,
2.5B ~g/l in the northeast pit, is well below the 275 ~g/l daily
maximum allowed by the LDEQ for discharge.
Barium, benzene and toluene were not found to contribute
significantly to a health risk but values detected during the RI
did exceed anticipated discharge limits. . All other constituents
detected during the RI are below the anticipated LDEQ discharge
1imi ts. Additionally, iron levels in the surface waters of the.
sal t water pond and the southeast marsh area were detected above
ambient water quality criteria (RAWQCR) levels.
Table #10 presents the contaminants of concern as discussed above,
with respect to their on-site detected concentrations and remedial
goals.
Estimates of the volume of water to be initially treated are
tabulated below. These volumes are based on a single removal
action. Additional volumes of precipitation collected during any
remedial action on the site sludge and associated soils will be
estimated wider those individual options.
Water Volume
Location (gallons)
Salt Water Pond 4,500,000
Northwest Pond 800,000
Northeast Pit 1,300,000
South pit 1,300,000
Sludge aDd As.ociated soil.
Figure #3 depicts the locations of the disposal pits and the areas
of contaminated sediment/soil in the salt water pond and the former
tank farm area.
For protection of human health, the RAOs for the waste pit sludge
and associated soils are to prevent migration of contaminants to
the ground water and surface water and to minimize the public's
-------
exposure to the material. In the human health BRA, an excess
cancer risk (greater than lX10-4) for future on-site residents
exposed to the sludge in the waste pits was identified. The
contaminants contributing most to that risk were the carcinogenic
PARs ("cPAHs") and arsenic through oral and dermal contact
pathways. Pesticides, PCBs and Dioxin/TCDD-Equivalents also were
determined to contribute to the risk for future residents and/or
current trespassers.
The pesticides and PCBs are not included as RAOs, due to the
uncertainty associated with the development of the related riaka.
PCBs were detected in only 2 of 40 sludge samples and the pesticide
risk is based entirely on non-detected values. The TCDD-Equivalent
risk is also not included as an RAO, aa the Agency for Toxic
Substance and Disease Registry CWATSDRW) normally recommends that
cleanup of material is not required unless the TCDD-Equi valent
values are above a calculated value of 1.0 ~g/kg. This procedure
has also been adopted by EPA Region 6.. Hone of the samples
analyzed during the RI had calculated TCDD-Equivalents above this
level. specific clean-up goals for these parameters are therefore
not developed. The material is, however, still being evaluated for
remediation since all of the site media that was found to
contribute a risk due to pesticides, PCBs or TCDD-Equivalents also
has a risk contributed to it for other constituents.
Noncarcinogenic risks (hazard index greater than 1) from exposure
to the sludge and/or soil, mainly from barium and the
noncarcinogenic PABs, were also calculated for future on-site
residents. Acetone and di-n-octylphthalate were also identified in
the BRA as contributing to the total risk of the sludge to on-site
residents. The risk posed by these compounds is due to up-take
into the food chain. Both of these compounds are common laboratory
contaminants and a firm conclusion that their detection is due to
site-related contamination is not possible. Specific remedial
goals for these compounds are therefore not developed. The
material is, however, still being evaluated for remediation since
the sludge has additional risks to it as a result of the other
constituents.
"
The environmental BRA identified potential risks to those aquatic
organisms that may be exposed to sAdiments in the salt water pond.
This risk is due to the levels of chromium, lead, manganese and
mercury detected during the RI. Lead and mercury levels were also of
potential concern to aquatic organisms in the ditch leaving the site.
Barium soil levels in the southeast marsh area were identified as
causing a potential risk to rabbit populations based on consumption
of possibly contaminated vegetation. Based on the lbdtecl nature of
the elevated elements in these locations, separate remedial goals are
not established for the environmental exposure. The barium remedial
goal is established utilizing human health concerns. With the
exception of the WHo Actionw alternative, for wbich the current risks
will remain, the remedial alternatives discussed in the following
-------
sections of this ROD do not provide for the retaining of any of the
surface water impoundments. An aquatic environment will therefore no
longer be present and aquatic remedial goals for soils and sediment
will not be applicable.
Table #11 presents the contaminants of concern as discussed above,
with respect to their on-site detected concentrations and remedial
goals.
The estimated volumes of waste materials in each area are presented
below. The sludge volumes are based on the surface area of the
pits and the estimated thickness of the sludge. The associated
soil volumes were estimated on the assumption that two feet of soil
around and under the northwest and northeast pits will be
remediated and one foot of soil around and under the south pit.
The internal berms and the top 1 ft of soil at the northwest corner
of the northwest pit berm will also be remediated. The results of
the sampling conducted on the soils indicated that several of the
key contaminants contributing to health risks in the sludge (for
example, carcinogenic and noncarcinogenic PAHs) are also present in
these soils.

Ground water
To protect human health, the prevention of ingesting contaminated
ground water from this Class :I:I ground water source is the primary
RAO for this media. The BRA evaluated the health-based risks for
future on-site residents who would use the site ground water as a
drinking water source. The evaluation inclicated that a n1ft11her of
inorganic constituents pose potential health risks throuqh ingestion
of ground water.
-------
Active ground water treatment is not warranted at this time for
several reasons: 1) it not believed that the sporadic presence of
ground water contaminants is a result of site activities. (This
belief is based on the fact that the naturally occurring inorganic
contaminants detected sporadically in the ground water were also
detected in similar concentrations in the upgradient background
well and because the natural soils underlying the sludge pits do
not appear to be contaminated with inorganics which indicates a
lack of migration), 2) the inorganic contaminants detected and
driving the potential risk are all associated with the solids that
can be filtered out of the ground water samples and not with the
ground water itself, and 3) due to the sporadic frequency and
location of the elevated detections, the area that may require
treatment can not be fully defined.
All of the a1ternatives considered, with the exception of the -No
Action- alternative, include future ground water monitoring. The
purpose for the ground water monitoring is to evaluate
effectiveness of the implemented remedial action and to confirm
EPA's determination that active ground water remediation is not
warranted at this time.
n1. DBScaIP.r10B or ALTBRDT:tVBS
A Feasibility study (-FS-) was conducted to develop and evaluate
alternatives to meet the RAOs for the PAB oil site. Remedial
alternatives were assembled from applicable remedial technology
process options and were initially evaluat.ed for effectiveness,
implementability, and cost based on engineering judgement. The
alternatives selected for detailed analysis were evaluated and
compared to the nine criteria required by the NCP (see Section
VIII. of this ROD). As a part of the remedial alternative
evaluation process, the NCP requires that a no-action alternative
be considered at every site.. The no-action alternative serves as
a point of comparison for the other alternatives.
The RAOs set for the PAB oil site (discussed in the SnmmAry of site
Risks) are the concentration levels below which the media can be
left in-place without treatment. This applies U) all media except
surface water, which must be removed regardless of contaminant
concentrations to allow for the excavation of contaminated
sediments and to provide space for the excavation, treatment and
disposal of contaminated sludges and soils.
The following alternatives to address contamination at the site
were evaluated in detail. Three addit.ional alternatives (described
as Alternatives 2, 3C, and 6 in the FS) were screened out earlier
in the evaluation process because of shortcomings described in
detail in the FS and are not presented here.

The descriptions and evaluations of remedial alternatives included
in this ROD basically differ only in their treatment of the
contaminated sludges and associated soils.
For the reasons discussed in the previoua section, the treatment of
ground water is not being considered as an implementable response
action and was not carried forward through the detailed development
of alternatives- However, because some inorganic contaminants were
detected in the ground water and several potential alt;ernatives
will result in wastes being left on-site in a disposal unit, a
ground water monitoring program will be implemented in all of the
evaluated alternatives-
As part of the ground water monitoring program that is included in
each of the following alternatives (with the exception of the WNo
-------
Action" alternative), additional development of the existing ground
water monitoring wells and installation of new wells is planned.
The purpose of this effort is to ensure that monitoring wells are
placed in appropriate locations to monitor potential migration of
contaminants from the disposal unit into the Abbeville unit of the
Upper Chicot Aquifer. Alternatives that include leaving wastes in
an on-site disposal unit will have at least 30-years of ground
water monitoring. Those alternatives that include final off-site
disposal of treated wastes will have S-years of ground water
monitoring. If future monitoring indicates the selected remedy
does not prevent the potential for ingestion of contaminated ground
water, EPA will investigate the need for active remediation of the
ground water.
In addition, preliminary screening of alternatives to address
surface water contamination revealed that institutional control or
containment measures would be ineffecti va in preventing human
exposure or off-site migration, therefore, removal and treatment
would be necessary. Therefore, all remedial alternatives discussed
below contain an evaluation of the same surface water removal and
treatment program.
The surface water removal and treatment program will consist of
pumping the existing surface water through a treatment process of
flocculation/sedimentation followed by sand filters and granular
activated carbon units with final discharqe to the site drainaqe
ditch. The discharge will be sampled to ensure compliance with
water quality criteria established by LDEQ in accordance with
section 303 of the Clean Water Act. All future surface water
runoff that comes into contact with any site contaminants during
the remedial action will also be collected and treated by the same
process.
EPA conducted a stabilization/solidification (WS/SW) treatability
study as part of the RI/FS. Information obtained from this study
will be useful in planning the future S/S treatability studies to
be conducted during the desigrn of the alternatives that include S/S
as part of the remedy (Alts. 3A, 38, 4, and SA). The results of
the S/S treatability study indicated limited, although hard to
quantify, success at permanently stabilizing the organic chemicals
of concern (cPAHs) contained in the waste material found in the
disposal pits.
Finally, all alternatives that result in treated waste remaining
on-site at levels that prohibit the future, unrestricted use of the
property wi~l trigger the statutory requirement for as-Year
Review. This review is conducted every S years as a check to
ensure that the implemented remedy is still protective and
performing as designed.
It is also important to note that because the wastes found on-site
are not, by definition or characterization, Whazardous wastesW as
-------
defined by the Resource Conservation and Recovery Act ("RCRA"),
then RCRA is not an "applicable" ARAR (ARARs are "applicable or
relevant and appropriate requirements" that all CERCLA remedial
actions must comply with). Therefore, none of the alternatives
evaluated during the FS will have to meet the requirements of the
RCRA Land Disposal Restrictions which only apply to "hazardous
wastes". Several "action-specific" portions of RCRA are considered
"relevant and appropriate", however, and are discussed later during
the comparative analysis and selected remedy sections of the ROD.
All of the treatment alternatives evaluated as part of the FS will
meet all other ARARs (such as the surface water discharge limits
established to meet local water quality criteria) and will conform,
where appropriate, to relevant RCRA treatment and design
requirements. In addition, according to disposal manifests
obtained during the RI, the wastes found at this site consist
mostly of, if not all, "non-hazardous oil field wastea" presently
regulated by the State of Louisiana under statewide Order 29-B.
For this reason, EPA and the state of Louisiana have determined
that this state regulation required consideration as an ARAR during
the evaluation of the potential remedial alternatives.
All cost and implementation times are estimates. The costs have a
degree of accuracy of +50' to -30' pursuant to the "Guidance for
conducting Remedial Investigations and Feasibility Studies Onder
CERCLA - Interim Final" OSWER Directive 9355.3-01., october 1.988.
A brief description of the six alternatives evaluated to address
the contamination at the site follows.

The No Action alternative is required by the BCP (40 cn 300) for
consideration. No action assumes that nothing would be done to
restrict site access, address the contaminants of concern, or
monitor contaminant migration. This alternative will not provide
overall protection of human health and the environment; compliance
with ARARs; long-term or short effectiveness; or, reciuce toxicity,
mobility or volume of hazardous substances and, therefore is not
favored by.EPA.

Ground Water/Surface Water Monitoring: at least 30 years
DescriDtion
For this alternative, there would be no remediation of the surface
water, the waste pit sludges and associated soils or the ground
water. The site would be fenced and institutional controls, in the
form of deed notices and signs, would be used to advise future
property owners and potential trespassers.of the potential health
risks from exposures to any of these wastes and associated soils.
Long-term ground water and surface water monitoring would be
conducted to monitor for changes in current conditions.

DescriDtion
This alternative provides for complete removal, treatment and
disposal of all impounded site surface water. The effluent from
the treatment system would be monitored for parameters and limits
set forth by the LDEQ.
Following the site surface water treatment, contaminated sludqe and
associated soils would be excavated and placed in an on-site JDiYing
bin or pug mill. Batches of the contaminated material would be
mixed with appropriate S/S agents as determined by a treatability
study (ies) performed durinq the remedial design phase of the
alternative. Upon completion of treatment, the material will be
removed from the mixing bin or puq mill and disposed of in a new
on-site excavation (final disposal unit), located in the former
salt water pond. Following disposal, a compacted clay cover would
be placed over the final disposal unit. A fence would be
constructed around the final disposal unit to prevent potential
-------
disturbances. The excavated and/or drained pits and ponds would be
backfilled up to grade level with common soil backfill, graded and
seeded. Ground water monitoring would be implemented to detect any
changes in the current level of constituents in the ground water
beneath the site.

This al ternati ve provides for complete removal, treatment and
disposal of all impounded site surface water. The effluent from
the treatment system would be monitored for parameters and limits
set forth by the LDEQ.
Following the site surface water treatment, contaminated sludge and
associated soils would be excavated and placed in an on-site mixing
bin or pug mill. Batches of the contaminated material would be
mixed with appropriate S/S agents as determined by a treatability
study (ies) performed during the remedial design phase of the
alternative. Upon completion of treatment, the treated material
would be loaded into trucks, hauled off-site and disposed of in an
off-site, permitted, hazardous waste landfill which is in
compliance with EPA's off-site policy.
Although no contaminated material would remain on-site, limited
ground water monitoring will continue following the implementation
of the alternative in order to evaluate the overall effectiveness
of the site remediation and to identify any changes in the current
levels of constituents in the ground water.

VIII. SUllllUY 01' DB COJIPUUIVB uaLYSI8 01' &LHRP'lIVB8
The EPA uses nine criteria to evaluate alternatives for addressing
a Superfund site. These nine criteria are categorized into three
groups: threshold, primary balancing, and modifying. The threshold
criteria must be met in order for an alternative to be eligible for
selection. The primary balancing criteria are used to weigh ..jar
tradeoffs among al ternati ves. The modifying criteria are taken
into account after state and public comment is received on the
Proposed Plan of Action.
-------
NINE CRITERIA
The nine criteria used in evaluating all of the alternatives are as
follows:
Threshold criteria
Overall Protection of Human Health and the Environment addresses
the way in which an alternative would reduce, eliminate, or control
the risks posed by the site to human health and the environment.
The methods used to achieve an adequate level of protection vary
but may include treatment and engineering controls. Total
elimination of risk is often impossible to achieve. However, a
remedy must minimize risks to assure that human health and the
environment are protected,.
ComDliance with ARARs, or "applicable or relevant and appropriate
requirements," assures that an alternative will meet all related
federal, state, and local requirements.
Primary Balancing criteria
Lena-term Effectiveness and Permanence addresses the ability of an
alternative to reliably provide long-term protection for human
health and the environment after the remediation goals bave been
accomplished.
L.
Reduction of Toxicitv. Mobilitv. or Volume of contaminants t~ouah
Treatment assesses how effectively an alternative will address the
contamination on a site. Factors considered include the nature of
the treatment process; the amount of hazardous materials that will
be destroyed by the treatment process; how effectively the process
reduces the toxicity, mobility, or volume of waste; and the type
and quantity of contamination that will remain after treatment.
Short-term Effectiveness addresses the time it takes for remedy
implementation. Remedies often require several years for
implementation. A potential remedy is evaluated for the lenCJtb of
time required for implementation and the potential impact on human
health and the environment durinq implementation.
ImDlementabilitv addresses the ease with which an alternative can
be accomplished. Factors such as availability of materials and
services are considered.
~ (including capital costs and projected long-term operation and
maintenance costs) is considered and compared to the benefit that
will result from implementing the alternative.
-------
Modifying criteria
state AcceDtance allows the state to review the'proposed plan and
offer comments to the EPA. A state may aqree with, oppose or have
no comment on the proposed remedy.
Communi tv AcceDtance allows for a public comment perioc:1 for
interested persons or organizations to comment on the proposed
remedy. EPA considers these comments in making its final remedy
selection. The comments are addressed in the responsiveness
summary which is part of this ROD.
SUMMARY OF THE COMPARATXVE ANALYS:IS OF ALTERNATIVES
The comparative analysis was conducted to evaluate the relative
. performance of each alternative, compared to the other
alternatives, in relation to each specific evaluation criterion.
Protection of JhDaaD Healtb aDd the BDvu:oJl1l8Dt
The No Action alternative (Alt. lA) does not provide protection of
human health and the environment as described in the BRA analysis,
therefore, it will not be discussed further in the criteria
analysis. The Limited Action/Institutional Controls alternative
(Alt. 1B), provides a reduction of the human health risks
associated with the site by reducing the potential for direct
contact with the site contaminants. The alternative does not
however, reduce the potential for miqration of contaminants from
the site and also does not reduce environmental risks.
The S/S alternative with on-site disposal (Alt. 3A), provides
protection of human health and the environment by reducing the
mobili ty of inorganic and organic contaminants although the extent
to which mobility would be reduced is unknown at this time. Direct
contact is eliminated by land disposal following the treatment.
On-site disposal requires engineering and institutional controls
and long term monitoring and maintenance to evaluate continued
protection.
On-site SIS with off-site disposal (Alt. 3B), provides protection
by reducing the mobility of inorganic and organic contaminants and
removing the materials from the site. This eliminates the need for
engineering controls and long term monitoring and maintenance.
Alternative 3B offers greater protection over Alternative 3A since
contaminants would not remain at the site. There would remain a
risk from the treated material, however, the risk would be
transferred to the potential receptors at the final disposal
location. Through proper management this risk can be minimized.
-------
The biological treatment alternative (Alt. 4), provides protection
by significantly reducinq the orqanic contaminants. The risks
associated with the inorqanic contaminants would be reduced by S/S.
On-site disposal requires enqineerinq and institutional controls
and lonq term monitorinq and maintenance to evaluate continued
protection. Since some contaminants would remain on site, the
overall protection would be between that obtained from Alternative
3A and Alternative 3B.
The on-site incineration alternative (Alt. SA), provides protection
by removinq and destroyinq the orqanic materials. The risks
associated with the remaininq metals and inorganic matter would be
reduced by S/S. On-site disposal requires enqineerinq and
institutional controls as well as long term monitorinq and
maintenance to evaluate continued protection. The overall protection
is anticipated to be sliqhtly hiqher than that of Alternative 4
because it is assumed that incineration would destroy nearly all of
the orqanic contamination whereas bior~:mediation technoloqies
qenerally only reduce orqanic contaminant concentrations to sliqhtly
hiqher levels than that achieved by incineration.
The off-site incineration alternative (Alt. 5B), provides the
greatest level of protection by removinq all hazardous materials
from the site and eliminating' the need for long' term maintenance
and monitorinq. Alternative 5B offers qreater protection over
Alternative 5A since contaminants would not remain at the site.
There would remain a risk from the treatment residual, however, the
risk would be transferred to the potential receptors at the final
disposal location. Throuqh proper manaqement this risk can be
minimized.
Compliance with Applicable a8l8V8Dt aDd &ppropriate aequir888DU
(DDs)
The Limited Action\Institutional Controls alternative (Alt.1B)
requires no remedial action and therefore compliance with ARAR8 is
not applicable. The remaininq alternatives (Alt. 3A, 3B, 4, SA,
5B) would all be performed in full compliance with all chemical-
and action-specified ARARs and other criteria, advisories and
quidelines which are applicable (i.8., surface water discharqe
limits established by LDEQ) or considered relevant and appropriate.
Action-specific ARARs to be considered as relevant and appropriate
would include the standards set by the Federal qovernment for the
operation of hazardous waste incinerators, 40 CFR 5264, Subpart 0,
for bioremediation landfarminq under Subpart H, and for Subpart G,
which requires the proper closure of hazardous waste units to the
extent that all material will be stabilized and disposed of to a
-------
level that would be protective of human health and the environment.
In addition, Statewide Order 29-B contains action-specific
requirements for waste pit closure, including specific chemical
limits for remaining soil contaminant concentrations. :If designed
properly, none of the active treatment alternatives would have
trouble complying with these relevant and appropriate ARABs.
There are no location-specific ARABs for the site.
Long-Tara Bff.otiven... and P8r.8&Deno.
The Limited Action\Institutional COntrols alternative (Alt. 18)
does not address the source of contamination. The barriers placed
around the source can be byPassed and would require long term
maintenance. This alternative is not effective for protection of
environmental receptors.
The SIS alternatives (Alt. 3A , 38) can potentially immobilize
organic and inorganic contaminants, however, final total
concentrations in the waste are not expected to be reduced below
remedial goals. The contaminants are immobilized but not
necessarily reduced or destroyed giving a lessor degree on
permanence than the alternatives that actively destroy all or a
part of the organic contaminants. Previous studies have shown
difficulty in effectively and permanently stabilizing wastes with
high levels of organic contamination. Actual SIS treatability
3tudies conducted on the PAS oil site wastes did not conf1ra the
effective and permanent stabilization of the organic chemical of
concern, PABs.
Both on-site and off-site disposal will minimize the potential for
future ground water contamination by encapsulating the waste,
however, both will require monitoring and maintenance to evaluate
the potential for future releases. Alternative 3A requires the
monitoring and maintenance at the on-site disposal unit compared to
similar activities at an off-site facility.
Based on historical studies on similar wastes, the bioloqical
treatment alternative (Alt. 4) is expected to significantly reduce
. (90-99%) the level of organic contaminants in the waste material
prior to the stabilization of the inorganic contaminants. This
alternative would therefore provide greater long-term effectiveness
and permanence than Alternatives 3A and 38. Long-tara maintenance
would still be required because the disposal unit containing the
stabilized material will need care to ensure it continues to
function properly.
The incineration alternatives (Alt. SA . S8) wou1.d remove and
destroy organic contaminants. Additional treatment (SIB) for
inorganic contaminants would be needed. With the destruction of
the organics, the long-term effectiveness of these alternatives
would be slightly greater than Alternative 4 because it is not
-------
expected that bioremediation technologies could reduce the organic
concentrations to levels that total thermal destruction can
achieve. For the site, Alternative 58 offers greater long-term
effectiveness over Alternative 5A since contaminants would not
remain and long term monitoring would not be required. The
monitoring of the overall effectiveness of the treatment process
would still be performed at the final disposal location.
aeductioD of Tozici ty , lIo):)i1i ty &D4 Volwae Through ~r.. meat
The Limited Action\Institutional Controls alternative (Alt.1B) does
not treat or destroy the contaminants and does not satisfy the
NCP's preference for treatment. The hazards posed by the principal
site contaminants are not reduced.
The remaining alternatives (Alt. 3A, 38, 4, SA, 58) allow for all
waste to be treated and the mobility of the contaminants to be
reduced. In addition to reducing tbe mobility, biological
treatment (Alt. 4) and incineration (Alt. 5A . 58) would
significantly reduce and I or 'eliminate the toxicity resulting from
the organic contaminants. The S/S process would not reduce the
organic concentration and would not necessarily reduce the toxicity
of the contaminants in the treated matrix. Some reduction in
toxicity may be achieved by changing the form of an inorganic
constituent, however, this reduction will be realized in all the
alternatives.
The total volume of waste will be reduced with the incineration
alternatives (Alt. 5A '58). The volume- of contaminated media,
however, will actually be increased with Alternatives 3A, 38, and
4. This volume increase is due to the. fact that the S/S and
bioremediation alternatives inherently involve the addition of
additives during the process to enhance treatment effectiveness.
Short Tara Bff.otiven...
The Limited Action\Institutional Controls alternative (Alt.1B) does
not increase the risk to the community or pose any significant risk
to the site workers but does not alleviate the potential impact on
the environment from existing conditions. The duration of
implementation for this alternative is less than for any other.
The remaining alternatives (Alt. 3A, 38, 4, 5A, 58) require
excavation of the hazardous materials but do not pose any
uncontrollable risks to site workers. The alternatives which
retain the hazardous materials on the site (Alt. 3A, 4, 5A) pose
less of a short-term threat to the community than the alternatives
which require off-site transportation (Alt. 38 . 58) through the
community to an off-site treatment or disposal facility due to the
inherent risks associated with transporting hazardous materials.
The incineration alternatives (Alt. 5A . 58) both require close
-------
..
control of the process to limit air emissions. Implementation
duration of these alternatives ranges from 16 to 39 months, not
including ground water monitoring. .
X-plementability
The S/S (Alt. 3A & 3B) and the biological treatment (Alt.4)
al ternati ves are readily implemented due to no unusual approvals or
coordination. All services and materials are readily available.
However, the duration of Alternative 4 depends on biological
activity which can be difficult to control.
The incineration alternatives (Alt. SA & SB) also have readily
available services and materials. . Implementing on-site
incineration (Alt. SA) remedies very often involve time consuming
administration obstacles such as trial burns and community
education exercises, while off-site incineration (Alt.SB) only
requires the use of a TSD facility which is in compliance with
EPA's off-site disposal pOlicy. Available incinerator capacity for
the volume of waste present could be a factor in the scheduling of
the off-site incineration.
Those alternatives with off-site disposal (Alt. 3B & SB) are more
easily implemented than those which require on site construction of
a land disposal unit (Alt. 3A, 4, & SA).
Coat
The estimated costs for the remedial alternatives range frail 1
million for the Limited Action/Institutional Controls alternative
(Alt.J.B) to 67.S million for the off-site incineration alternative
(Alt.SB). The least expensive alternative that provides treatment
of the contaminants is the stabilization and on-site disposal
alternative (Alt.3A).

PAS Oil site (see Appendix #3). No commenta regarding the other
alternatives were provided.
cOJll8uaity Aooeptanoe
EPA solicited input froll the community on the remediation
alternatives proposed to address sediment and surface soil
contamination at the PAB Oil site. The comments received from the
public, both local citizens and potentially responsible parties,
indicate that the community is supportive of the proposed remedy.
All comments received during the public comment period and the EPA
responses are in the attached Responsiveness Sn-ary.
-------
1:%. 'l'HB SELECTED 1nnnmy
Based on consideration of the requirements of CERCLA, the
comparative analysis of al ternati ves, and public comments, the EPA
has determined that Alternative 4 (Surface water treatment,
biological treatment, residual SIS, on-site disposal, ground water
monitoring) will best provide a remedy that is protective of human
health and the environment.
As discussed in section I:V of this ROD, the specific remedial
objectives determined to be necessary at the PAB Oil site are:
1. Prevent direct contact, ingestion,
disposal pit sludges and associated soils.
and migration of the
2.
Prevent direct contact with contaminated surface waters.
3. Prevent the potential for human exposure to contaminated
ground water.
The selected remedy (Alternative 4) will meet these objectives by:
- treating all sludges and associated soils found at the site with
contaminant concentrations above the RAOs (as described at the end
of section VI. and Table #11 of this ROD) using bioremediation,
followed by stabilization/solidification and on-site disposal and
monitorinq.
- treating, monitoring, and discharging all surface water presently
located on-site, as well as any future surface water contacting
contaminated media during the remedial action, using activated
carbon and sand filtration units.
- monitoring ground water through the use of new and existing
monitoring wells to ensure that contamination source treatment
actions are successful and ground water quality degradation does
not occur.
l.
since all contaminated sludges and associated soils above the RAOs
will undergo treatment, the long-term effectiveness and permanence
of the selected remedy is expected to be excellent. There are not
expected to be any unmanageable short-term risks associated with
this remedy, and this remedy complies with .all ABARs. The selected .
remedy utilizes permanent solutions and alternative treatment
technologies to the maximum extent practicable, and will be cost
effective. The selected remedy will also satisfy the preference
for treatment as a principal element. In addition, both the public
and State have indicated acceptance of the selected remedy.
Therefore, the selected remedy provides the best balance among
al ternati ves with respect to the criteria used to evaluate
remedies.
-------
The primary balancing criteria that weighed heaviest and
contributed most to the selection of Alternative 4 over the other
evaluated alternatives were the long-term' effectiveness and
permanence criteria and cost criteria. All of the active treatment
alternatives could basically provide a significant and adequate
degree of reduction of toxicity, mobility, or volume through
treatment as well ciS short-term effectiveness and implementability.
It became clear, however, from the results 'of the RIIFS (as well as
the SIS treatability study), that the alternatives involving
bioremediation and incineration provided. greater degree of long-
term effectiveness and permanence than the alternatives that
contain SIS as the primary treatment process. The bioremediation
and incineration technologies actually destroy the organic
contaminants as opposed to simply immobilizing them in a solid
matrix. In addition, the estimated cost of the bioremediation
alternative (approximately $13 million) versus the estimated cost
of the cheapest incineration alternative (> $20 million), while
providing a similar degree of long-tara effectiveness and
permanence, significantly favored selection of Alternative 4.
Based on other successful bioremediation studies that have been
conducted on wastes similar to those found at the PAB oil site, it
is expected that bioremediation will successfully degrade the
organic contaminants present at the site. The selected remedy
requires that detailed treatability studies be Performed during the
Remedial Design (or earlier if appropriate) to determine the
optimum conditions for biotreatment of the wastes and residual SIS
and final disposal. Treatability studies. for SIS were performed
during the RIIFS and data fram those studies will be useful in
designing the SIS portion of the remedy.
A more detailed description of the selected remedy follows,
including major estimated cost assumptions. It should be noted
that certain engineering considerations of the remedy may change
as a result of the treatability study findings andlor during the
remedial design. The only significant change anticipated regards
the actual bioremediation process to be implemented. The
treatability study will help determine the most cost effective
bioremediation process to be used to meet the RAOs and it may
differ from the solid-phase bioreactor process outlined in the
followinq discussion. A more detailed cost estimation for the
selected remedy is included as Appendix #4.
BDqiD.eriDq a_.4ial D..ip
. The engineering remedial action plana will include: Work Plan,
Health and safety Plan, Sampling and Analysis Plan, Quality
Assurance Project Plan, and operation and Maintenance Plan.
. The engineering remedial design will include intermediate reports
for review and 100 percent Final COnstruction Plans and
Specifications ready for bidding.
-------
site Preparation
. The clearing, grubbing and stripping of site vegetation (grasses,
bushes, small trees) will be performed on three acres of the site
including the site drainage ditch, the former tank farm area, the
berms associated with the disposal pits and ponds and the pond
islands/mounds.
o
. Site fencing includes a 6-ft high chain link fence with 3 strands
of barbed wire and a 20-ft rOlling gate at the site entrance. This
fence will be constructed around the entire site for health, safety
and security precautions during the site remedial activities. This
fence will be removed after completion of the remedial action. An
additional fence will be constructed around the final disposal unit
prior to the removal of the perimeter fence.
. A concrete decontamination pad with curbs will be constructed for
trucks and other large equipment. A sump, a wastewater storage
tank with a pump and a high pressure steam sprayer will be utilized
at the decontamination pad. The collected decontamination water
will be tr~ated in the same manner as the site surface water.

. Improvements to the existing main site access road will be
required in order for it to be upgraded to a haul road capable of
continuous heavy load traffic in wet conditions. The cost estimate
also includes upgrades to other site access routes around the site
and for providing a suitable base for a common working area.
. A pre-engineered steel storage building will be constructed. The
cost estimate assumed a 100 ft by 100 ft steel building with a
small corner office and large drive-in doors. It also includes a
100 ft by 100 ft, 8 inch thick, concrete slab on grade.
. An electric hook-up will be made and a non-potable water supply
well will be installed to provide the site with the necessary
utilities for the remedial activities.
l
Surface Water Tr..t:aent
. All impounded surface water on site will be treated.
Confirmation sampling at the time of remediation may allow water in
the northwest pond and possibly the salt water pond to be partially
drained without treatment. The treatment system effluent will be
monitored. The parameters and sample frequency will meet suggested
guidelines set forth by the WEQ.
. Granulated activated carbon ("GAC") units and high flow rate sand
filters will be purchased for the remediation. Other major
components of the treat.aent system (pumps, hoses, etc.) will be
leased, since they can be obtained locally and will only be used
periodically during the remaining remedial activities.
-------
. The GAC units will not need to have the carbon replaced durinq
the duration of the remediation (oriqinal carbon will not be
spent). At the completion of the project, the .used carbon will be
vacuumed out of the GAC units with a vacuum truck and placed with
the site material (sludqe, etc.) to be treated and disposed.
. The filter sand and removed solids will be placed with the site
material (sludqe, etc.) to be treated and disposed.
. Two treatment trains will be operatinq simultaneously. GAC units
will be in parallel, not series.
. A total of 300 qpm (both treatment trains combined) operatinq for
22 hours/day on a total of 9,187,000 qallons (on-site water plus
accumulated rain water) will take 24 days. The total volume of
water to be treated takes into account the local averaqe annual
precipitation rate of 59 inches per year (0.16 inches per day)
fallinq on the estimated surface area of ponds, pita and inside
berms (510,600 ft2).
. The O&M costs include additional water treatment required after
ini tial pump-down and durinq the remaininq portions of the remedial
action. Treatment is assumed to occur on an averaqe of one week
durinq every month of the remedial implementation phase.

. Confirmation samples will be taken from the underlyinq soil in
each remedial area prior to excavation/treatment completion in
-------
order to verify that all of the contaminated material above the
remedial action objectives has been excavated for treatment.
Biological Tr..taent
. Cost estimates for the selected remedy were made on the
assumption that bioloqical treatment of the sludge and contaminated
soil will be accomplished utilizing an aerobic, solid-phase
bioreactor. This system was considered to be more advantageous
than a land treatment system due to the limited available acreage
on-site and longer estimated time frames to achieve treatment
goals. It is important to note here that the final bioremediation
treatment process and associated costs implemented at the PAS oil
site will be determined based upon results from the treatability
studies and other design considerations.
. For cost assumption purposes, it is assumed that two five-unit
sets of aerobic, solid-phase bioreactors will be used. Both sets
of bioreactors will be utilized initially for treating contaminatecl
sludge. Then, when contaminated soil is ready for treatment, one
five-unit set of bioreactors will be converted for the required
conditions necessary for the specific treatment of soil. Each
bioreactor tank would hold a maximum of 40 yd3 of contaminated
media with a retention time of 5 to 1.0 days. Therefore, a
potential volume of up to 400 yd3 of material may be treated in one
work week. These details would have to be further defined in a.
treatability study. Little volume reduction will be realized from'
biological treatment, however, the resulting residue from the
treated sludge will have considerably lea. oil content which may
improve residue handling operations.
. It is assumed that biological treatment of most of the soils
underlying the pits will be sufficient in reducing contaminant
levels such that no further treatment (i.e., S/5) will be required.
This will be possible because the RI data did not show elevated
levels of inorganics in this media which would require treatment
using S/S. The resulting residue therefore would be disposed of
directly into the on-site disposal unit after consideration is
given to the strength of the material to support the disposal unit
cap. The sludge and other associated soil residue vith elevated
inorganic contaminants, however, vill require S/S prior to disposal
in the on-site disposal unit.
. AcCording to the FS, costs for biological treatment of the
contaminated sludge and soil have been estimated to be $1.60 Per
cubic yard. This includes mobilization, material hancllinq,
treatment operations and demobilization.. To obtain this cost,
comparisons were made of the contaminated media from this site to
previous projects at other sitea in which similar contaminated
-------
media has been successfully treated under similar conditions.
Biological treatability studies have not yet been performed on the
contaminated media from this site, so more definitive costs and
design parameters cannot be estimated.
Residual. Solidification/Stabilisation
. The biologically treated residuals will be stabilized and placed
as backfill in a final disposal unit to be created in the east-
northeast portion of the salt water pond. Confirmation samples
will be collected from the treated material in order to verify that
treatment design criteria are met (as further discussed later in
this section of the ROD). The final disposal unit will have, &II a
minimum, a 2 ft thick compacted clay cover or other suitable cover
as determined by the treatability studies.
. A treatability study performed on the sludge at the site
indicated that sufficient treatment of inorganics can be obtained
through S/S. This estimate assumes that the optimum S/S agent mix
utilized in the treatability study will also be used for the
residuals. This SIS agent mix consists of 95' portland cement (94
pcf), 3' S.D.-1 (organo-philic clay) (93.5 pef), l' flyash (75 pcf)
and l' of equal amounts of slag powder and Fecls (100 pef).
Additional treatability study work is included as part of the
engineering remedial design to further evaluate the binder aix
including the evaluation of commercial or proprietary binders. A
major determination to be made during the treatability study is the
degree to which the residuals will require organic stabilization
(i. e., immobilization). This factor will have a great impact on
the final binder design and cost.
. The total volume of biologically treated residuals requiring S/S
is estimated at 16,100 yd~. Sludge, assumed to have a unit weight
of 100 pcf, accounts for 16, 000 yd~ of the total residuals
requiring additional treatment. The remaining 100 yd~ is soil,
assumed to have a unit weight of 120 pet. Therefore, the total
weight of residuals to be solidified, stabilized is estimated at
21,800 tons.
. The S/S agent will be mixed at a rate of 25' by dry weight.
Therefore, an estimated 5,450 tons of S/S agent will be required.
. . The $85 per yd~ unit cost of S/S the residuals ($65 per yd~ of
residual and $20 per yd~ for labor) includes the on-site delivered
cost of the S/S agents ($190 per ton) and the manual mixing (by a
trackhoe mixer) of the SIS agents with the residuals and water, if
necessary, from the site water well.

The volumes required for backfill inelude the volumes of
material necessary to fill the disposal pits and ponds up to
qround level following sludge and soil removal. The existing
berms will be leveled and pushed into the pits and ponds for
use as backfill.
-------
. The unit costs to backfill the pits and final disposal unit
reflect both the purchase and placement costs of suitable off-site
borrow consisting of common soil ($10/yd3), clay (used as a 2-foot
thick cover) and topsoil ($20/yd3). Both.the common and the clay
soil types are to be compacted. There is suitable clay on-site due
to the excavation of the final disposal. unit to avoid off-site
purchase; therefore, the clay placement unit cost ($5/Yd3) includes
placement and compaction only.
. Geotechnical testing will be required for the placement of the
S/S residuals in the final disposal unit. The compacted cOJlDRon and
clay soil backfill will also require testinq. Permeability testinq
of field and laboratory prePared samples will be required for
backfilling the final disposal unit. Other geotechnical testing
performed on the final disposal unit will include Proctor
compaction, Attenberg limits and in-situ soil density and moisture
content determination.
Ground Watar
. Four additional shallow (40 ft), 2 inch PVC ground water
monitoring wells will be installed on or adjacent to the site to
monitor the up- and down-qradient ground water quality near the
final disposal unit and the entire site as a whole.
. The unit cost of $4,000 per well includes all labor and materials
to install and develop each well. The price also includes the
oversiqht of one geologist/engineer.
. :In an effort to reduce the hiqh susP8Dded solids content
encountered previously, prolonqed pumpinq/purqinq (at least 200
gallons per well) will initially be performed on 12 of the 16 site
monitoring wells. These wells will be sampled during the OUI
activities. :It is assumed that the four wells adjacent to the pits
will be abandoned to facilitate remediation.
. The purged water will not require collection for off-site
disposal.

. The site ground water will be monitored by sampling 12 site
monitoring wells twice a year for 30 years.
-------
. The unit cost of $63,000 per year for monitoring well sampling
and analysis includes two sampling events. The costs within each
sampling event include analytical costs, estimated at $1,750 per
well, travel and other direct costs for two technicians for a total
of eight days travel and field work.
. The $1,750 per well analytical cost includes analyzing for TCL

u.s. EPA CLP report format.
. Semi-annual engineer's reports will be developed throughout the
30 year ground water monitoring periocl to evaluate and present the
most recently collected ground water quality data.
All of the above specifics identified in the description of the
selected remedy are presented for cost assumption PurPOses. These
specifics will be better defined during the final design.
TRBATKDT GOALS
As discussed earlier, Tables #10 and #11 describe the established
RAOs for surface waters and sludges and associated soils at the PAS
oil site. All contaminated media found at the site above these
RAOs will be collected and treated as described by the selected
remedy. Treatment goals have been established to determine if the
selected remedial actions are effective before on-site disposal
(sludges and associated soils) or discharge (surface water) can
occur.
SURFACE WATER
The treatment goals for surface water are the same as the RAOs.
The treatment goals are based on Federal and State Water Quality
Standards and discharge limitations established by the State of
Louisiana. As mentioned earlier, pre-RA monitoring may indicate
certain areas of the site that contain surface waters below the
RAOs. This surface water will not require treatment and can be
directly discharged into the site drainage ditch. The areas that
contain surface water with contaminant concentrations above the
RAOs will be treated to at least the RAO levels before discharge.
The state of Louisiana will be responsible for establishing the
final discharge limitations prior to treatment of the surface
water, thus, these treatment goals may be added to and/or changed
from those stated in Table #10.
-------
SLUDGES AND ASSOCIATED SOILS
The treatment goals for the sludges and associated soils are based
on the statutory objectives of reducing the toxicity and/or
mobility of the contaminants, to the maximum extent practicable, as
well as reducing actual or potential risk to human health and the
environment to within acceptable values. The specific treatment
goals for the PAB oil selected remedy are as follows:
. To use biological treatment to reduce the total organics,
measured as total petroleum hydrocarbons (TPHs), to the
condition at which biological treatment is considered no
longer effective (as defined by future treatability studies)
for all sludges and associated soils which are visibly
contaminated and/or with initial total cPAB concentrations
above the RAO of 3 ppm and TPB concentrations above l' (10,000
ppm) . This will ensure treatment to the maximum extent
practicable and maximize the benefit of SIS treatment if
necessary for organics.
. When optimum treatment is achieved, TPH concentrations will
be reduced at least 90' or to 10,000 PPJI (factoring in
adjustments for dilution) and cPAB concentrations will be
reduced to within the acceptable risk range of 10.8 to 10-4 .
In addition, total noncarcinogenic PABa will be reduced to a
HI1.0 will
also be addressed during the S/S treatment process.
Measurement of S/S effectiveness with regard to toxicity
and/ or mobility will be adjusted for dilution and will comply
with the Region 6 draft SIS Effectiveness Definition attached
to the ROD. (see Appendix #5).
-------
In addition, for other previously unidentified carcinogenic
compounds (those compounds that were not listed in the RAOs or
treatment goals as compounds of concern). that upon confirmatory
sampling after excavation or treatment, become identifiable and
exhibit a total risk greater than 1.0.1, must also be addressed. For
noncarcinogenic compounds, maximum concentrations left untreated
will be those with an HI less than or equal to 1..0.
GROUND WATER
As mentioned earlier, ground water will be monitored for at least
30 years after completion of the remedial action as part of the OUi
and 5-Year Review activities at this site. If at any time during
this monitoring EPA determines that source treatment actions were
ineffective in preventing ground water quality degradation which
poses a risk to existing or future users, then additional
investigative and treatment alternative actions will be
implemented. These additional actions would be implemented under
a separate Operable Unit and ROD.
criteria to be evaluated will include statistical changes in ground
water contaminant concentrations, the identification and
characterization (including risk assessments) of contaminant
plume(s) attributed to the site, and comparisons with appropriate
drinking water standards. The ground water monitoring program will
be developed during the Remedial Design and contained in the
operation and Maintenance Plan.
x. S'!ATUTORY DE'!DJIJ'Im'!IOJJS
EPA's primary responsibility at Superfund sites is to select
remedial actions that are protective of human health and the
environment. Section 1.21. of CERCLA also requires that the selected
remedial action for the site comply with applicable or relevant and
appropriate environmental standards established under Federal and
state environmental laws, unless a waiver is granted. The selected
remedy must also be cost effective and utilize treatment or
resource recovery technologies to the maximum extent practicable.
The statute also contains a preference for remedies that include
treatment as a principal element. The following sections disCU88
how the selected remedy for the PAB oil site meets the statutory
requirements.
Protection of HWDaD Health and the BnviroJ1Jllent
In order to protect human health and the environment, the
contaminated sludges, associated soils, and surface water that
exceed RAOs will undergo a combination of excavation, treatment and
-------
final containment. These media will be treated and contained to
meet the performance standards, or treatment goals, set forth in
the ROD. These performance standards will assure that the site
risks fall within the acceptable excess cancer risk range of 10.4
to 10.e and noncarcinogenic hazard index will be reduced to less
than 1.0. The performance standards will also assure that 1)
direct contact wi th contaminated sludges, associated soils and
surface water will cease, 2) contaminants will cease to act as a
potential surface and ground water contamination source, and 3)
ground water monitoring will enable EPA to monitor the remedy's
effectiveness and prevent the future possibility for human exposure
to potentially contaminated ground water. .
The selected remedy protects human health and the environment by
reducing levels of contaminants through treatment and containment.
Of all the alternatives evaluated for the contaminated media at the
site, the selected remedy provides the best, cost effective
protection to human health and the environment. No unacceptable
short-term risks will be caused by implementing this remedy.
Compliance With ARARs
Each component of the selected remedy will meet all applicable or
relevant and appropriate requirements. The ARARs are presented
below:
Chemical-Soecific ARARs

Maen4aent to Louiai&D& stat..ieS. order .0. 2'-B, 4at8cl OOto!»8r
20, 1"0. The State of Louisiana baa identified Sections
129.B.6 and 129.H.7 as relevant and appropriate for the
selected remedy because they address pit closure and land
treatment requirements for non-hazardous oil field waste (as
defined by statewide Order 29-8) which were disposed at the
PAB oil site.
As discussed in EPA' s August 1988 CERCLA ComDliance wi 1:h other Laws
Manual lEPA/540/G-89/0061, action-specific ARARs should be refined
as appropriate during remedial design, when specific information
reqardinq size and operation of treatment facilities bacomes
available.
Cost E~~ectiveness
J..
EPA believes that the selected remedy ia cost effective in
mitiqatinq the threat of direct contact and reducing the potential
for ground water contamination from site wastes. Section
300.430 (f) (ii) (D) of the NCP requires EPA to determine cost
effectiveness by evaluating the following three of the five
balancing criteria to determine overall effectiveness: long-term
effectiveness and permanence, reduction of toxicity, mobility or
volume through treatment, and short-term effectiveness. OVerall
effectiveness is then compared to cost to ensure that the remedy is
cost effective.
The estimated present worth cost for the selected remedy is
$13,113,000. This alternative costs almost $5,000,000 more than
the stabilization alternative (with on-site disposal) yet the
selected remedy is significantly more effective and protective of
human health and the environment due to the significant differences
in reduction in toxicity and level of permanence achieved with
organic destruction versus immobilization. Also, the selected
-------
remedy provides a similar degree of overall protectiveness as the
more costly incineration alternatives ($13,113,000 vs. $21,070,000
and $67,557,000 respectively).
utilization of Permanent Solutions and 2'reatment or Resource
Recovery 2'echnologies to tbe HlI%imWll Brt:ent Practicable
EPA believes the selected remedy represents the maximum extent to
which permanent solutions and treatment/resource recovery
technologies can be utilized in a cost effective manner for the PAS
Oil site.
Of those alternatives that are protective .of human health and the
environment, and comply with ARARa, EPA has determined that the
selected remedy provides the best balance of trade offs in terms of
long-term effectiveness and permanence, reduction in toxicity,
mobility, or volume achieved through treatment, short-tara
effectiveness, implementability, costs, the statutory preference
for treatment as a principal element, and taking into consideration
State and community acceptance.
.Pre:terence :tor 2'reatment as a Principal. Blement
The statutory preference for remedies that employ treatment of
principal threats as a principal element will be satisfied through
implementation of the selected remedy. This remedy will utilize
bioremediation to address organic contamination of the sludgea and
associated soils, stabilization to address the inorganic
contamination (and any residual organic contamination above the
RAOs remaining after the bioremediation step, and GAC/sand fi1.ters
to address the contaminated surface water.
%J: . DOCOKBI1TA!1':&:OII 01' 8:&:CDI:&:J':&:~ CBUtGBS
The Proposed Plan was released for public comment in March 1993.
The Proposed Plan identified Alternative 4, surface water
treatment, excavation, bioremediation, residual S/S, and on-site
disposal as the preferred alternative for the PAS Oi1. site. EPA
reviewed all written anei verbal comments submitted durinCJ the
public comment period. Upon review of thea8 comments, it vas
determined that, with the exception of the change of the arsenic
remedial goal from 14 ppm to 10 ppm for sludges and associated
soils, no significant changes to the remedy, as originally
identified in the proposed plan, were necessary.
Background data is being used to establish the remedial goal for
arsenic in the sludges and associated soils because native 80ils in
the area of the PAS Oil site contain naturally occurring arsenic at
levels above the 1X10.' point of departure (0.36 ppm). EPA had
-------
originally proposed the arsenic remedial goal of 14 ppm based on
the "maximum" background soil sample collected during the R.I. Both
the State of Louisiana and the local citizens have commented that
Statewide Order 29-B contains a limit of 10 ppm for arsenic in
soils upon closure of a waste pit containing non-hazardous oil
field waste.
Further statistical evaluation of the background soil data
indicates that the arsenic 95% UCL of the arithmetic mean would be
less (approx. 8.2 ppm) than the established state criteria of 10
ppm. For this reason, EPA has determined that the appropriate
remedial goal for arsenic in the sludges and associated soils would
be changed to 10 ppm. .
Because the existing PAS oil site background soil data base
includes three discrete samples whose values were greater than this
revised remedial goal (10.3 ppm, 11.0 ppm, and 14.1 ppm),
appropriate methods will need to be developed to evaluate
attainment of this goal during the post-excavation confirmatory
sampling process to ensure that minor, infrequent exceedances do
not result in unnecessary remediation. The procedures to be used
during the confirmatory sampling process will be developed in
accordance with Methods for Evaluatina the Attainment of CleanuD
Standards, Volume 1: Soils and Solid Media, EPA 230/02-89/042.

) Background samples collected 0-3 ft in depth,
4 . The clean-up level of carcinogenic PAHs is based on a residential exposure scenario and falls within EPA's acceptable risk range of I E-4 to
lE-6. The 3 mg/kg is expressed as a carcinogenic Benzo (a) Pyrene equivalent which corresponds to a risk of 3E-5. Although EPA has
flexibility within its risk range for identifying an appropriate clean-up goat, the decision to use 3 mg/kg was an effort to be consistent with
similar past clean-up decisions within the Region.
, For noncarcinogenic PAHs, the following risk based concentrations shall be used in order to achieve a hazard index (HI) of I: 16,500 mg/kg,
Acenaphthene; 82,000 mglkg, Anthracene; 11,000 mg/kg, Fluoranthene; 11,000 mglkg, Fluorene; 1100 mg/kg, Naphthalene; and 8000 mg/kg
Pyrene. A conservative estimate of 8000 mg/kg will be used as the surrogate risk-based concentration for other noncarcinogenic PAHs that
do not have a reference dose.
