Dear Sin '
The U.S. Environmental Protection Agency (EPA) Region 4 has reviewed the above
subject decision document and concurs with the remedy of Institutional Controls at PSC 16 and
No Further Response Action Planned at PSC 17 at Operable Unit 3. This remedy is supported by
the previously completed Remedial Investigation, Feasibility Study and Risk Assessment Reports,
as well as the earlier action taken under an Interim Record of Decision. The remedy of ,
Institutional Controls and No Further Response Action Planned is protective of human health and
the environment.
As specified in the Institutional Control Plan, PSC 16 will be inspected on an annual basis.
by the MCLB, Albany Environmental staff. It is EPA's expectation that this will be done to
ensure that the institutional controls are in place and being adheTed to by the base. As described
in the Institutional Control Plan for PSC 16, any proposed changes in use of the site "are subject
to approval by USEPA Region IV and GEPD." EPA will review the need for future remediation,
monitoring, or changes in institutional controls under all applicable statutes, if any changes in use
are proposed. In addition, it is imperative that the current excellent coordination between the
MCLB, Environmental personnel and the MCLB Construction personnel continue and that all
proposed projects and that all proposed projects that could impact the area encompassed by PSC
16 be reviewed by the MCLB Environmental office. These measures will result in the elimination
of any inadvertent noncompliance with the institutional control requirements.

RECORD OF DECISION
SITE NAME AND ADDRESS
Marine Corps Logistics Base
Operable Unit 3
814 Radford Blvd
Albany, Georgia 31704-1128
STATEMENT OF PURPOSE AND BASIS
This Record of Decision (ROD) document presents the final response for Operable
Unit (OU) 3 at the Marine Corps Logistics Base (MCLB) , Albany. It was developed
in accordance with the Comprehensive Environmental Response, Compensation, and
Liability Act as amended by the Superfund Amendments and Reauthorization Act, and
to the extent practicable, the National Oil and Hazardous Substances Contingency
Plan (NCP). This decision is based on the site's Administrative Record, which
is on file at the Environmental Branch Office, Facilities and Service Division,
Building 5501, MCLB, Albany, Georgia 31704, and at the information repository in
the Dougherty County Public Library, Albany, Georgia.
OU 3 consists of two potential sources of contamination (PSC), PSC 16
Building 7100 Polychlorinated Biphenyl (PCB) Area and PSC 17 Depot Maintenance
Activity Chrome Area. A remedial investigation and feasibility study (RI/FS) was
conducted at OU 3 from October 1991 to August 1992. A baseline risk assessment
(RA) was contained within this RI/FS that examined hypothetical situations for
current land use in which an older child could trespass on OU 3, and a
hypothetical future land use of OU 3, which assumes residential use by adults and
children, and associated exposures to utility construction workers. These
hypothetical situations represent the most sensitive receptor and conservative
risk estimates for OU 3. The RA evaluated both cancer and noncancer risks.
According to the NCP for Superfund sites, the acceptable cancer risk range is
from 1 in 10,000 (1x10"*) to 1 in 1 million (IxlO"6) depending on site-specific
conditions. Although the estimated risk of IxlO"6 is the point of departure in
determining the need for a response action, site-specific conditions at OU 3
indicate that application of the acceptable risk range is appropriate. Site-
specific conditions that make application of the acceptable cancer risk range for
OU 3 is the industrial site conditions and low probability of receptor contact
with the contaminated soils.
The RA conducted for the subsurface soil at PSC 16 resulted in risks acceptable
to USEPA for carcinogens (3xlO~5) and noncarcinogens (a hazard index [HI] less
than 1). The HI for PSC 16 subsurface soils was 0.7. The contaminated surface
soils at PSC 16 had been excavated to a depth of 44 inches and disposed of at a
permitted landfill prior to the 1991 RI so they were not investigated as part of
this OU 3 RI/FS.
ALB-OU3.ROO
SAS.07 97
-I-
-------
The total carcinogenic risks estimated at PSC 17 for current and future exposures
were within the acceptable risk range specified by U.S. Environmental Protection
Agency (USEPA) . The highest cancer risk for PSC 17 was 5xlO'6, for potential
future residential risk. However, for future residential land use, the estimated
noncancer risk of 5 exceeded the limits (HI of 1) identified by USEPA. This
potential risk was primarily associated with exposure to chromium and lead found
in the surface and subsurface soils. In addition, the results of the ecological
RA indicated possible adverse effects associated with surface soil exposure by
certain wildlife if the site was not cleaned up.
A complete explanation of the baseline RA is presented in the OU 3 RI/FS , dated
July 1992. This document also includes the identification of applicable or
relevant and appropriate requirements (ARARs), identification of treatment
alternatives, and comparison with the nine USEPA criteria (including compliance
with ARARs) . The treatment alternatives for PSCs 16 and 17 included no action,
limited action (fencing and security measures), capping, excavation with ex situ
treatment and landfilling, and excavation and landfilling (no treatment) of soil.
The ARARs and identification and/or evaluation of interim remedial alternatives
for PSCs 16 and 17 are also summarized in the OU 3 Interim ROD (MCLB, 1992).
Therefore, an interim ROD was prepared and signed in August 1992 to implement
remedial actions that would reduce the potential risks at PSCs 16 and 17. A
design document was then issued in August 1993 that provided the necessary
information for a contractor to perform the remedial actions at PSCs 16 and 17.
These interim remedial actions were conducted between November 1993 and January
1994. A Remedial Action Report was prepared and approved by the USEPA Region IV
and Georgia Environmental Protection Division (GEPD) in March 1997.
The interim remedial action at PSC 16 included the construction of a multilayer
cap, installation of a chain-link fence and locked gate, warning signs, and
installation of monitoring wells with periodic sampling and analysis of
groundwater beneath the site to ensure that the remaining low levels of PCBs did
not migrate into the groundwater.
The interim remedial action at PSC 17 included the excavation of contaminated
soils to concentrations protective of humans and the environment. The excavated
soils were transported offbase to a permitted facility for treatment and
disposal. Clean backfill material was used to restore the site.
Based on the implementation of the interim remedial actions, the potential risks
associated with the remaining surface and subsurface soils at PSCs 16 and 17 are
within ranges deemed acceptable by the USEPA Region IV. Under this final
response, no further treatment of surface and subsurface soils is deemed neces-
sary at PSCs 16 and 17; however, land-use restrictions will be implemented at
PSC 16, in accordance with the 1992 interim ROD. No surface water or sediment
was encountered at OU 3. Groundwater at OU 3 will be evaluated under OU 6, a
separate basewide groundwater OU.
Both the USEPA Region IV and GEPD concur with the selection of final institution-
al control for PSC 16, and a no further response action planned for PSC 17
surface and subsurface soils.

-------
DESCRIPTION OF THE SELECTED REMEDY
This final response proposes that land-use restrictions be enforced at PSC 16 via
MCLB, Albany's Base Master Plan document. This response also specifies that no
further treatment, containment, or restricted access is deemed necessary for PSC
17. These remedial actions address the surface and subsurface soil at OU 3. No
surface water or sediment was present at the two PSCs. Groundwater beneath OU
3 will be addressed under a continuing basewide investigation within OU 6,
including the groundwater monitoring associated with the PSC 16 multilayer cap.
DECLARATION STATEMENT
This final response supports the protection of human health and the environment,
complies with Federal and State requirements that are legally applicable or
relevant and appropriate to the response action, and is cost-effective. This
final response addresses both surface and subsurface soil at PSC 16 and PSC 17,
whereas the groundwater will be addressed by the continuing basewide investiga-
tion within OU 6.

1.0 SITE NAME. LOCATION. AND DESCRIPTION
Marine Corps Logistics Base (MCLB), Albany is an active facility occupying 3,579
acres east-southeast of the city of Albany, Georgia. Land bordering MCLB, Albany
to the south, east, and northeast is primarily agricultural or rural open space.
Most of the land to the northwest and west of the base is residential and
commercial.
Operable Unit (OU) 3, composed of potential sources of contamination (PSCs) 16
and 17, is located in the central portion of the base. Figure 1-1 identifies the
location of MCLB, Albany and the approximate location of the PSCs that make up
OU 3.
1.1 PSC 16. PSC 16 (Building 7100 Polychlorinated Biphenyl [PCB] Area) is the
former location of an electrical transformer and supporting concrete pad. It is
approximately 12 by 16 feet in size, located on the south side of Building 7100
(Figure 1-2). During an inspection conducted as part of a PCB transformer
change-out program, evidence of leaking transformer oil was observed on the
concrete pad beneath the transformer. Soil sampling and analysis conducted in
1990 confirmed the presence of PCBs and semivolatile organic compounds (SVOCs)
in soil beneath the former transformer pad.
In 1990, prior to the remedial investigation (RI), contaminated surface soil at
PSC 16 was excavated to a depth of 44 inches and disposed of offbase in a
permitted landfill. The excavated area was then backfilled with clean soil.
Additional sampling and analyses conducted in 1991 indicated that elevated
concentrations of PCBs remained in the subsurface soil below 44 inches. The
concentrations ranged from 310 milligrams per kilogram (mg/kg) at 44 to 48 inches
below land surface (bis) to 24 mg/kg (9 to 10 feet bis). Based on these
confirmatory sampling results, an RI was conducted to determine the extent of
contamination in the subsurface soils. Subsequently, preventative measures to
protect human health and the environment were implemented at PSC 16 in 1993.
These measures will be discussed later in this document.
1.2 PSC 17. PSC 17 (Depot Maintenance Activity [DMA] Chrome Area) is located
adjacent to the Central Repair Building (Building 2200), between a drum storage
area and the Weapons Test Firing Building (Building No. 2226) (Figure 1-3). The
Central Repair Building historically contained metal-plating operations. A
release of chrome plating waste occurred at a spot approximately 40 feet
northeast of Building No. 2226 sometime prior to October 1989. The contaminants
migrated downhill and covered an area of approximately 1,150 square feet
(Figure 1-3, Area A). The spill area contained no vegetation and was stained
with a dried yellowish material. In 1990 and 1991, sampling and analyses
indicated that the spill area was contaminated with chromium and lead. In 1992,
additional soil sampling indicated chromium contamination at depths of 2 and 7
feet below the spill location.
In addition, an isolated location of soil containing low concentrations of
polycyclic aromatic hydrocarbons (PAHs) and PCBs was also identified east of the
gravel driveway to Building 2226 (see Figure 1-3, Area B) . Surface and
subsurface soil remedial actions were implemented at PSC 17 in 1993, which will
be described later in this document.

2.0 SITE HISTORY AND ENFORCEMENT ACTIVITIES
MCLB, Albany currently serves as a U.S. military logistics center controlling the
acquisition, storage, maintenance, and distribution of combat and support
material for the U.S. Marine Corps (USMC) . In addition, the base is used for
military training and other tasks and functions as directed by the Commandant of
the USMC.
MCLB, Albany has generated various types of solid and liquid wastes over the
years, including hazardous wastes. The hazardous wastes include electroplating
wastes containing heavy metals, organic solvents from stripping and cleaning
operations, and waste fuel and oil.
Beginning in 1985, three investigations were performed to assess and characterize
PSCs identified at MCLB, Albany. These investigations, the 1985 Initial
Assessment Study (IAS), 1987 Confirmation Study, and 1989 Resource Conservation
and Recovery Act (RCRA) Facility Investigation (RFI) resulted in the placement
of MCLB, Albany on the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA) National Priority List.
2.1 IAS. An IAS was conducted by Envirodyne Engineers, Inc., at MCLB, Albany
in 1985 to identify and assess PSCs posing a potential threat to human health or
the environment due to contamination from past hazardous materials disposal
practices. Eight PSCs were identified at MCLB, Albany based on historical data,
aerial photographs, field inspections, and personal interviews. All eight PSCs
(PSCs 1-8) were evaluated to determine contaminant characteristics, migration
pathways, and potential receptors. PSCs 16 and 17 had not yet been identified
at the time of this IAS.
The primary pathways identified for possible migration of contaminants include
erosion, surface water runoff, and groundwater transport. The predominant
direction of regional groundwater flow is west toward the Flint River,
approximately 2.7 miles from the base. Potential receptors identified include
aquatic organisms in the receiving waters, predators and other animals relying
on these areas for food and water, and humans using the Flint River for
recreational purposes.
The IAS concluded that six of the eight PSCs (PSCs 1, 2, 3, 5, 6 and 7) warranted
further investigation under the Navy Assessment and Control of Installation
Pollutants program to assess long-term impacts. The primary recommendation of
the study was to conduct a confirmation study to confirm or disprove the
existence of the suspected contamination and to quantify the extent of any
existing problems. Specifically, this Confirmation Study would determine (1)
whether a threat to human health or the environment existed, (2) the extent of
contamination, and (3) the potential for contaminant migration.
2.2 CONFIRMATION STUDY. > A confirmation study was conducted by McClelland
Engineers at the MCLB, Albany facility in 1986 at nine PSCs: the six PSCs
recommended for further evaluation by the IAS and three additional PSCs
identified as threats to human health or the environment (PSCs 9, 10, and 11).
ALB-OU3 ROD
SAS.O7.97

-------
As previously stated, PSCs 16 and 17 had not yet been identified. McClelland
Engineers completed the Confirmation Study and submitted a final report in 1987
(McClelland, 1987). Based on the confirmatory study results, additional
investigation was recommended for PSCs 1, 3, 6, 9 and 11.
2.3 RFI. Subsequent to the 1987 Confirmation Study, nine PSCs (PSCs 1, 2, 3,
5, 6, 7, 9, 10 and 11) were identified as solid waste management units by the
Georgia Environmental Protection Division (GEPD) in the Part B RCRA Permit for
MCLB, Albany. Terms of this permit required that an RFI be conducted at each of
the PSCs to determine the nature and extent of releases and the potential
pathways of contaminant migration to the environment. Applied Engineering and
Science, Inc., completed the RFI and submitted a final report in 1989 (Applied
Engineering and Science, Inc., 1989). Of the nine PSCs studied in the RFI, only
PSCs 7 and 9 did not require further investigation. PSCs 16 and 17 were
identified subsequently to this RFI and evaluated during the remedial investiga-
tion and risk assessment (RI/RA) in 1991.
2.4 RI/RA. In July 1991w the Department of the Navy, representing MCLB, Albany,
entered into a Federal Facilities Agreement (FFA) with the GEPD and the U.S.
Environmental Protection Agency (USEPA) Region IV. The FFA established a
procedural framework and schedule for developing, implementing, and monitoring
appropriate response actions at the facility in accordance with the provisions
of CERCLA, RCRA, the National Oil and Hazardous Substances Contingency Plan
(NCP), Superfund guidance and policy, and the Georgia Hazardous Waste Management
Act.
The conclusions of the three previous investigations indicated a need for
additional data collection over the entire installation. Between 1987 and 1991,
the total number of PSCs to be investigated at MCLB, Albany increased to 24 PSCs.
Available data on the 24 PSCs were sufficient to indicate the requirement to
characterize the extent of contamination, assess releases, and develop responses.
As a result of more recent investigations, two additional PSCs, 25 and 26, were
identified, resulting in a total of 26 PSCs. According to the FFA, 14 of the
PSCs required an immediate remedial investigation and feasibility study (RI/FS),
2 PSCs required RCRA investigations while the remaining 10 PSCs required site-
screening activities. As a result, ABB Environmental Services, Inc. (ABB-ES),
was contracted under the Comprehensive Long-Term Environmental Action, Navy
contract to prepare and execute RI/FS workplans, site-screening workplans, and
associated planning documents for PSCs at MCLB, Albany.
Under the RI/FS process, groups of PSCs are defined as OUs due to their
proximity, similarity of waste, or similarity of investigative techniques or
potential response actions. OU 3, consisting of PSCs 16 and 17, was developed
because the proximity and contamination at the two sites is limited to surface
and subsurface soils. No surface water or sediment is present at these sites and
groundwater is deferred to the OU 6 basewide groundwater investigation. A Final
RI/FS report for OU 3 was released in July 1992 (ABB-ES, 1992e). The results of
these investigations for OU 3 are presented below.
2.4.1 PSC 16. Building 7100 PCB Area PSC 16 is a former transformer and
supporting concrete pad location, approximately 12 feet by 16 feet in area,

adjacent to Building 7100. During an inspection conducted as part of a PCB
transformer change-out program, evidence of leaking transformer oil was observed
on the concrete pad beneath the transformer. Two sampling investigations were
then conducted in response to this discovery. The transformer and associated
concrete pad were removed and properly disposed of, and then a series of
excavation and sampling events were conducted by Remtech and BCM Engineers in
1990. Based on the results of confirmatory sampling by BCM Engineers, the USEPA
Region IV conducted further investigations on the PSC 16 subsurface soil in 1991.
In 1990, Remtech and BCM Engineers conducted a series of sampling and excavation
programs at the prior location of the electrical transformer and concrete pad.
Initial observations identified stained soil beneath the concrete surface
indicating the need for soil excavation. Soil was excavated to a depth of 20
inches across the entire 12-foot by 16-foot area, then disposed of offsite at a
permitted facility. Confirmatory soil samples were then collected from the
excavated area. Each subsequent round of soil excavation and confirmatory
sampling indicated the need to excavate more soil from PSC 16. A total depth of
44 inches of soil was subsequently removed from the area; however, BCM Engineers
found that the contamination continued further into the subsurface soils. Based
on these results, the USEPA Region IV initiated an RI at PSC 16 to determine the
depth and extent of contamination. The results of this investigation were
submitted to Southern Division, Naval Facilities Engineering Command (SOUTHNAV-
FACENGCOM) in December 1991 (USEPA, 1991b) .
Figure 2-1 is a plan view of PSC 16, indicating the locations of all soil samples
collected during each phase of the PSC 16 RI. In addition, a summary table of
all samples collected is included as Table 2-1. This table presents the sample
identification number, depth, sample date, sample location, and rationale.
2.4.2 PSC 17. DMA Chrome Area The DMA Chrome Area is located to the rear of the
Central Repair Building (Figure 2-2), between a drum storage area and the Weapons
Test Firing Building (Building 2226) . A spill of chrome plating waste occurred
at a spot approximately 40 feet northeast of Building 2226. The material
subsequently migrated downslope, affecting an area measuring approximately 110
feet long by 8 to 12 feet wide at the southeast (source) end, tapering down to
1 to 2 feet wide at the northwest (downhill) end (Figure 2-2) . The spill area
was mostly devoid of vegetation and contained a small quantity of dried yellowish
material. Soil directly south of the chrome spill area was excavated during
construction of a driveway that leads to the Weapons Test Firing Building
(Building 2226) . The excavated soil was placed on the sides of the driveway and
regraded. The chrome spill area is directly on the north side of the driveway
and was partially covered with excavated soils (presumably clean) during this
activity.
Three investigations were conducted at PSC 17: (1) a May 1990 soil sampling and
analysis performed by Westinghouse Environmental and Geotechnical Services, Inc.
(Westinghouse), (2) a September 1991 RI soil sampling performed by USEPA Region
IV, and (3) a February 1992 soil sampling performed by ABB-ES.
In May 1990, Westinghouse collected 28 soil samples from 14 soil borings located
in and near the spill area (Table 2-2). Two samples were collected from each
location, with one sample collected from the ground surface and one from a depth

of 2 feet bis. These samples were analyzed by the extraction procedure (EP)
toxicity method for the eight EP toxicity metals and hexavalent chromium. At the
time of the sampling, regulatory criteria for the eight EP toxicity metals were
in effect. These criteria, which consisted of maximum concentration values, were
used to evaluate waste disposal options and to develop cleanup objectives at
hazardous waste sites.
An evaluation of these results indicated that further investigation of the PSC
was warranted. As a result, the USEPA's Environmental Compliance Branch
performed RI sampling of the spill area in September 1991. The purpose of the
sampling was to define the extent of contamination, gather sufficient data to
perform a risk assessment (RA) and feasibility study (FS), and develop a proposed
plan for the area. The details of the investigative approach taken during this
event are presented in the USEPA Revised Study Plan for Sites 16 and 17,
September, 1991 (USEPA, 1991a).
During this sampling event, a total of 13 soil samples was collected from 7
locations. One surface (upper 6 inches) soil sample was collected at an
upgradient (or background) location, two surface soil samples were collected
south and north of the spill area, and four locations within the spill area were
selected for subsurface sampling (Figure 2-2). Depending on the location,
sampling began at the surface, and deeper discrete sampling occurred at 3- , 6,
and 9-foot depths (Table 2-2). Each sample was analyzed for volatile organic
compounds (VOCs), SVOCs, pesticides and PCBs, and metals. The results of this
sampling were presented in the previously mentioned report entitled Site
Investigation Report for Operable Unit 3 (USEPA, 1991b), submitted to Naval
Facilities Engineering Command by the USEPA in December 1991.
The results of the 1991 RI analysis indicated the need for limited additional
sampling to provide data that would distinguish relative concentrations of
trivalent chromium (less toxic, less mobile species) versus hexavalent chromium
(more toxic, more water soluble species). These data were required to support
fate and transport analysis and the human health and ecological risk assessments.
In addition, PAHs, pesticides, and PCBs were detected in the previous background
sample (17-1). Additional background samples were, therefore, collected to
provide more data on the extent of contamination and to identify native soil
concentrations.
In February 1992, ABB-ES collected 10 soil samples from 4 locations (Figure 2-2).
Three of the locations were in the source area, and the fourth was a background
sample. These sample locations are adjacent to locations of samples 17-3, 17-5,
and 17-7, collected in 1991 by USEPA. Two samples were collected at each of the
three locations, a shallow sample from a depth of 1 to 2 feet (below fill
material from constructing a gravel driveway into Building 2226) and a deeper
sample from approximately 7 feet bis.
The background sample location was on the east side of the driveway, approxi-
mately 80 feet southeast of the spill source area. Two samples were collected
from this location: one shallow sample from a depth of about 1 foot and a deeper
sample collected from about 7 feet bis.
All samples collected during the February 1992 sampling event were analyzed for
total chromium, toxicity characteristic leaching procedure (TCLP) chromium, TCLP

lead, hexavalent chromium, and lead. In addition to these analytes, the
background sample was also analyzed for pesticides, PCBs, and SVOCs. All samples
were collected and analyzed in accordance with USEPA Level III Data Quality
Objectives. The complete laboratory report of these analyses was presented in
the 1992 RI/FS (ABB-ES, 1992e).
Because of regulatory changes, the TCLP replaced the EP toxicity method in 1991.
Maximum contaminant values for 28 elements and compounds were ncluded in the
TCLP regulations. These values are also used to determine waste ^..sposal options
and to develop cleanup objectives at hazardous waste sites.

subsurface soils at PSCs 16 and 17. In accordance with the 1992 interim Record
of Decision (ROD), groundwater monitoring will be conducted at PSC 16. This
monitoring and reporting will be conducted as part of the basewide groundwater
investigation, under OU 6. Land-use restrictions will also be implemented for
PSC 16 through the MCLB, Albany Master Plan document. PSC 17 will not require
further treatment, containment, or restricted access. There was no surface water
or sediment at either PSC 16 or PSC 17. This response action was concluded in
accordance with the NCP and USEPA regulatory guidance for Superfund sites.

5.0 SUMMARY OF SITE CHARACTERISTICS
This section summarizes the regional geology, hydrogeology, and ecology in the
vicinity of MCLB, Albany. The nature and extent of contaminants is also
presented for OU 3. A more detailed presentation of this information is
available in the RI/FS report.for OU 3 (ABB-ES, 1992e).
5.1 GEOLOGY. MCLB, Albany is located in the Coastal Plain Physiographic
Province, which is made up of layers of sand, clay, sandstone, and limestone.
These layers of soil and rock extend to a depth of at least 5,000 feet bis. Each
layer has been identified and named by geologists according to its composition
and physical properties.
The soil and rock layers at MCLB, Albany in descending order, are the clayey
overburden, the Ocala Limestone, and the Lisbon Formation. The overburden layer
is made up mostly of clay with some silt and sand. The Ocala Limestone is
divided into an upper unit and a lower unit. The upper unit is a lime mud or
chalky paste. The lower unit is hard, dense rock that has been dissolved by the
movement of water along fractures to form underground caves and springs. The
Lisbon Formation is a hard, clayey limestone. These are the soil and rock layers
that control the movement of underground water in the first 350 feet bis at MCLB,
Albany. Figures 5-1 and 5-2 present a generalized geologic section of the Albany
area.
5.2 HYDROGEOLOGY. Soil and rock layers are also grouped and named according to
how well water moves through them. Layers that bear water to wells are called
aquifers, and layers that cannot bear water are called confining layers. The
clayey overburden and the upper unit of the Ocala Limestone are considered
together to be a confining layer. The lower unit of the Ocala Limestone is the
major water-bearing zone of the Floridan aquifer. The Lisbon Formation forms a
confining layer beneath the Floridan aquifer.
The Floridan aquifer is recharged by rainfall that slowly percolates down through
the confining units and through sinkholes. Movement of water in the Floridan
aquifer is generally westward toward the Flint River, where it discharges to the
river through springs (Figure 5-3).
Most irrigation wells and household water wells near MCLB, Albany draw water from
the Floridan aquifer. City water wells may also draw water from the Floridan
aquifer, although most of the city water is produced from deeper aquifers.
5.3 ECOLOGY. The majority of forested land in the vicinity of the base is
vegetated with longleaf pine flatwoods, the most extensive plant community in the
southern coastal plain. Pine flatwoods grow in Florida, Georgia, South Carolina,
and North Carolina.
The pine flatwoods habitat commonly found at MCLB, Albany supports diverse plant
and animal life, including invertebrates (e.g., insects and worms), reptiles, and
amphibians. A number of mammals inhabit the pine flatwoods community, although
no mammal is exclusive to this habitat. Pine flatwoods also provide habitat for

a variety of birds, including seed- and insect-eaters, flycatchers, and aerial
predators (e.g., owls and hawks).
The presence of two rare and threatened species has been confirmed at the base.
The American alligator (Alligator mississippiensis) , now classified as
threatened, has been documented in wetland habitats at the base; this semi-
aquatic species is present throughout the southeast. Bachman's sparrow
(Aimophila aestivalis) , a State and federally listed "rare" species, is also a
possible resident of the dry, open pine forests at MCLB , Albany; this large,
secretive sparrow is a year-round resident of southern Georgia. The red-cockaded
woodpecker (Picoides borealis) , a federally listed endangered species, occurs
almost exclusively within this pine flatwoods habitat; however, there are no
known records for this species at MCLB, Albany.
5.4 NATURE AND EXTENT OF CONTAMINANTS. The nature, extent, and concentration
of hazardous substance contamination at OU 3 was studied during the RI .
Potentially hazardous substances detected at OU 3 and the media affected are
summarized in tables by PSC and media sampled and analyzed. Units are generally
presented in micrograms per kilogram (pg/kg) or mg/kg or milligrams per liter
EP toxicity analysis).
Concentrations of analytes detected by laboratory analyses are reported in
or mg/kg for soil samples and mg/^ for water samples. For instance, a concentra-
tion of 3,100 mg/kg for iron means that 3,100 milligrams of iron are present in
each kilogram of soil. A kilogram is a unit measure of weight equal to about 2.2
pounds. One thousand micrograms equal 1 milligram, 1,000 milligrams equal
1 gram, and 1,000 grams equal 1 kilogram. A liter is a unit measure of volume
roughly equal to a quart.
5.4.1 PSC 16. Building 7100 PCB Area The source of contaminants at PSC 16
appears to be from an electrical transformer historically located on the concrete
pad. In early 1990, Remtech and BCM Engineers conducted soil sampling in
conjunction with three excavation programs that removed a total depth of 44
inches of soil from the area.
In February 1990, Remtech collected four soil samples from the bottom of a 20-
inch excavated area. Although the original laboratory data are not available,
the Remtech data summary indicated that PCBs ranged from 20 to 187 mg/kg. Two
composite samples collected from drummed soil and analyzed for disposal purposes
was found to contain PCBs at 44 and 766 mg/kg.
In June 1990, BCM Engineers excavated additional soil from PSC 16 (volume
unknown) and collected confirmatory soil samples from five locations (S-l through
S-5; Figure 2-1). Two samples were collected from each location: one from the
newly exposed soil surface and one from a depth of 2 feet. These confirmatory
sampling results identified concentrations of Aroclor-1260 in the surface samples
and concentrations of "PCB/Soil" in the deeper samples. Based on these
confirmatory sampling results, additional soil was excavated to a total depth of
44 inches bis, and the entire excavation area was backfilled with clean soil.
Analyses of the samples collected by BCM Engineers indicated the presence of one
PCB, Aroclor-1260, in soil remaining beneath the excavated area at concentrations
up to 1,204 mg/kg.

-------
In response to the detection of Aroclor-1260 in the remaining subsurface soil,
the USEPA Region IV conducted an RI at PSC 16 beginning in September 1991. Seven
soil samples were collected from two locations during the event. One sampling
location was selected at the approximate center of the PSC and one background
sample location was selected in an open field approximately 300 feet southwest
of the PSC. Six samples were collected at 1-foot intervals from the center
sampling location at the following depths; 3 to 4 feet (immediately beneath the
clean replacement fill), 4 to 5 feet, 5 to 6 feet, 6 to 7 feet, 7 to 8 feet, and
9 to 10 feet. One grab surface soil sample was collected from the background
location. Figure 2-1 presents the sample locations.
Samples from the center of PSC 16 were analyzed for pesticides and PCBs, VOCs,
and SVOCs. Two of the six samples from the center of PSC 16 were also analyzed
for inorganic elements (Table 2-1). The background sample was analyzed for
pesticides, PCBs, VOCs, and SVOCs. All of the analytical results from the 1990
(Remtech and BCM Engineers) and 1991 (USEPA) sampling events for preexisting
conditions (prior to the 1992 Interim ROD) are summarized in Table 5-1. The
summary table includes only those analytes detected at concentrations above the
laboratory quantitation limit.
5.4.2 PSC 17. DMA Chrome Area The potential source area at PSC 17 was
identified by the visual staining of the surface soils, lack of green vegetation,
and small pile of waste remaining on the surface. In the 1990 sampling event,
28 soil samples were collected from 14 locations (Tables 5-2 and 5-3; Figure
2-2). No designated background sample was identified for this sampling event.
All samples were analyzed for the eight EP toxicity metals and hexavalent
chromium. All metals except for chromium were present, if detected, at less than
the maximum concentration of contaminants for toxicity characteristic (40 Code
of Federal Regulations [CFR] 261.24). Chromium concentrations exceeded the EP
toxicity maximum concentration in samples from two locations near the spill area
(Table 5-4). At that time there was no EP toxicity maximum concentration for
hexavalent chromium.
In 1991, USEPA Region IV collected 13 soil samples from 7 locations, including
1 background location (Figure 2-2). All of the samples were analyzed for 24
inorganic elements. A total of nine inorganic elements were detected in one or
more samples at concentrations that exceeded either twice the PSC 17 background
concentration or, for those inorganic elements which were not detected in the
background sample, twice the detection limit in the background sample.
Chromium concentrations exceeded twice the PSC-specific background (75 mg/kg) in
nine surface samples located in and just downgradient from the source area.
These sample concentrations ranged from 160 mg/kg to 49,000 mg/kg. Lead was
present at concentrations exceeding the maximum PSC-specific background
concentration (260 mg/kg) in the two surface samples from the source area
(610 mg/kg and 3,900 mg/kg).
In 1992, ABB-ES collected a total of 10 samples from three source area locations
and one background location (Figure 2-2). The samples were analyzed for total
chromium, hexavalent chromium, total lead, TCLP lead, and TCLP chromium. Total
chromium, hexavalent chromium, and lead were present in both the deep and shallow
samples from the source sampling location at concentrations significantly
(greater than two times) above the PSC-specific background concentrations
(Table 5-5) .

The average surface soil background value for total chromium (40 mg/kg: includes
1991 and 1992 data) at PSC 17 was exceeded in one shallow source area sample.
The average subsurface soil background value for total chromium (18.6 mg/kg:
1992 data) was exceeded in one deep source area sample. Hexavalent chromium was
not detected in the background samples and was detected in two shallow and deep
samples from the spill source area. Lead was present at greater than two times
the PSC-specific background concentration in only the deep source area sample.
Chromium concentration in the TCLP extract from shallow and deep source area
samples exceeded the Maximum Toxicity Characteristic Concentration of 5.0 mg/,0
(40 CFR 261.24). However, the concentrations of chromium in other samples and
lead in all samples did not exceed their respective maximum concentration.
During the 1992 sampling, chromium and lead were not detected in the TCLP extract
from the background samples. Only chromium was detected in the extract from the
shallow spill area sample at 9,453 micrograms per liter (pg/£), whereas chromium
(8.302 Mg/-O and lead (38 ng/S-) were detected in extract from the deep spill area
sample.
All of the analytical results for PSC 17 are summarized in Tables 5-2 through
5-5. These summary tables include only those analytes detected at concentrations
above the laboratory quantitation limit.

6.0 SUMMARY OF SITE RISKS AND INTERIM REMEDIAL ACTIONS
The OU 3 RI analytical data were evaluated to determine whether the individual
compounds were site related (i.e., resulting from historical waste disposal
practices) or associated with base background data. Based on this evaluation,
a list of chemicals of potential concern (CPCs) were developed for each medium
investigated at OU 3. Tables 6-1 and 6-2 present the CPCs for each PSC and
medium. These CPCs were then evaluated within the baseline RA.
6.1 OU 3 BASELINE RA. An RA was prepared for precleanup (or preexisting)
conditions at OU 3 in accordance with USEPA Risk Assessment Guidance. This
guidance reflects a conservative approach to risk assessment to ensure that
subsequent cleanup decisions are protective of human health and the environment.
The RA estimates or characterizes the potential present and future risks to human
health and the environment. Three factors were considered when evaluating the
risks associated with exposure to surface and subsurface soils at OU 3.
• The extent of contamination present at the site and surrounding areas.
• The pathways through which people and the environment are or may poten-
tially be exposed to contaminants at the site.
• The potential toxic effects of site contaminants on humans and the
environment.
6.1.1 PSC 16. Building 7100 PCS Area Human health and environmental risks
associated with the exposure to subsurface soils were evaluated in the RA at
PSC 16. As indicated before, contaminated surface soils (to a depth of 44
inches) were removed in a prior cleanup action and replaced with clean soil. No
surface water or sediment was present at PSC 16. PSC 16 is also surrounded by
paved areas and an adjacent building; therefore, an ecological RA was not
required since ecological receptors could not access the contaminated subsurface
soil.
The CPCs for subsurface soil at PSC 16 (Table 6-1) were evaluated as part of the
RA. Potential exposure to these CPCs could only occur as the result of soil
excavation operations. Construction workers and future residents (adult and
child) could be exposed to contaminants for a limited time period through
accidental ingestion of, and/or skin contact with subsurface soils in an open
excavation.
The RA evaluated both cancer and noncancer risks. According to the NCP for
Superfund sites, the estimated risk of IxlO"6 is the point of departure in
determining the need for a response action. However, depending on site-specific
conditions, the acceptable cancer risk range of 1 in 10,000 (1x10"*) to 1 in 1
million (IxlO"6) may be used. The industrial site conditions and low probability
of receptor contact with the contaminated soil at OU 3 support the use of this
risk range. The RA conducted for the subsurface soil at PSC 16 resulted in an
estimated carcinogenic risk of 3xlO"5 and a noncarcinogenic risk (hazard index
[HI]) of 0.7.

6.1.2 PSC 17. DMA Chrome Area Human health and ecological risks associated with
exposure to the soils at PSC 17 were evaluated and compared to USEPA acceptable
risk values. The CPCs identified and evaluated at PSC 17 are listed in Table 6-2
for both surface and subsurface soils. Exposure pathways for these CPCs on MCLB,
Albany personnel working near (or walking by) were determined to be direct skin
contact and the breathing of windblown particles.
Exposures associated with future residential use of the PSC included exposure to
both children and adults to contaminated surface soils. The exposure pathways
consisted of incidental ingestion and direct contact with soils and breathing
windblown soil particles. Workers could also be exposed to subsurface soils
during construction of future residential housing units at the PSC. Exposure
pathways for these workers would include incidental ingestion, the breathing of
windblown dust particles, and direct contact with soils for a limited period of
time.
The total carcinogenic risks estimated at PSC 17 for current and future exposures
were within the acceptable risk range specified by USEPA. The highest cancer
risk for PSC 17 was 5xlO~6, for potential future residential risk. However, for
future residential land use, the estimated noncancer risk of 5 exceeded the
limits (HI of 1) identified by USEPA. This potential risk was primarily
associated with exposure to chromium and lead found in the surface and subsurface
soils. In addition, the results of the ecological RA indicated possible adverse
effects associated with surface soil exposure by certain wildlife if the site
were not cleaned up.
For a complete explanation of the baseline RA results for OU 3, please refer to
the RI/FS document (ABB-ES, 1992e) , located a-t the MCLB, Albany Environmental
Office and the Dougherty County Library.
6 . 2 COMPLETED INTERIM REMEDIAL ACTIONS AT OU 3. The OU 3 RI/FS (ABB-ES, 1992e)
included the RA, identification of applicable or relevant and appropriate
requirements (ARARs), identification of treatment alternatives, and comparison
with the nine USEPA criteria (including compliance with ARARs). The treatment
alternatives for PSCs 16 and 17 included no action, limited action (fencing and
security measures), capping, excavation with ex situ treatment and landfilling,
and excavation and landfilling (no treatment) of soil. The ARARs and identifica-
tion and/or evaluation of interim remedial alternatives for PSCs 16 and 17 are
also summarized in the OU 3 Interim ROD (MCLB, 1992). Based on their review of
the OU 3 RI/FS (which included the RA) , the USEPA Region IV and GEPD in 1992
approved the interim remedial actions proposed by SOUTHNAVFACENGCOM and MCLB,
Albany for OU 3. The interim remedial action for OU 3, in accordance with the
signed interim ROD, included construction of a multilayer cap at PSC 16 and the
excavation and off-base stabilization/disposal of contaminated soils from PSC 17.
Remedial activities began in November 1993, and construction was completed in
January 1994.
6.2.1 PSC 16. Building 7100 PCS Area The interim remedial action at PSC 16
included
installation of a multilayer cap over the surface area,
reinstallation and maintenance of security fencing,
ALB-OU3 ROD

-------
• excavation and offbase disposal of sediment in the bottom on the catch
basin adjacent to PSC 16, and
« installation of monitoring wells and monitoring of groundwater quality.
The multilayer cap at PSC 16 (Figure 6-1) provides a barrier that prevents human
exposure to hazardous materials. The cap also reduces the chance of rainwater
inducing contaminant migration into groundwater by directing the majority of
surface water away from the site. The multilayer cap is now permanent.
During construction, debris in the area that was contaminated with PCBs greater
than 10 micrograms per 100 square centimeters was also disposed of in a
permitted, hazardous waste landfill.
In addition, five monitoring wells were installed around PSC 16 to periodically
monitor groundwater quality to ensure none of the contaminants move without being
detected. Groundwater was collected from the monitoring wells at PSC 16 twice
during 1996 for laboratory analysis. The analysis indicated that no groundwater
contamination occurred from transformer oils. Future groundwater monitoring at
PSC 16 will be conducted as part of OU 6 (an ongoing basewide groundwater
investigation).
Institutional Control Plan fICP). An ICP was prepared by SOUTHNAVFACENGCOM and
MCLB, Albany to ensure future protection of the cap constructed at PSC 16
(Appendix B). The ICP restricts construction and storage activities at PSC 16
and limits physical access to the property.
Should the decision later be made to transfer ownership of the property
encompassing PSC 16 to any private person or entity, then the Navy shall either
(1) take all actions necessary to remediate the site to then existing residential
cleanup standards prior to effecting such transfer, or (2) deed record with the
Dougherty County Register of Deeds appropriate restrictive covenants prohibiting
future residential usage of the property or disturbance of the site's surface cap
through routine excavation or building/utility construction, maintenance, or
repair activities on or immediately adjacent to the site. Should the Navy not
have the requisite legal authority to record such deed restrictions, then it
shall take all steps necessary to ensure that the cognizant federal agency with
such authority does so unless the property is remediated to residential standards
prior to such transfer. Should cleanup of the site not be effected to
residential standards, then notification will be given to USEPA Region IV and
GEPD at least 30 days prior to any conveyance of title to the site to any third
party(ies), and the purchaser(s) of the site will be advised via the deed
documentation as to then existing site conditions and any/all associated
institutional controls and long-term monitoring requirements.
Once the final ROD for OU 3 is signed, the ICP will be implemented into daily
operations of the facility through MCLB, Albany's Master Plan (SOUTHNAVFACENGCOM,
1993).
6.2.2 PSC 17. DMA Chrome Area The purpose of the interim remedial action at
PSC 17 was to remove all contaminated soil to the established cleanup concentra-
tions specified by GEPD and USEPA in the 1992 Interim ROD. These goals were
derived to ensure that the noncancer HI for the remaining surface and subsurface

soils would be equal to or less than 1 in accordance with USEPA guidance. The
cleanup goals for PSC 17 surface and subsurface soil consisted of the following
(ABB-ES, 1992e):
Area "A"
Chemicals 0-2 feet below surface Below 2 feet
Lead < 265 mg/kg *
Chromium < 81 mg/kg < 266 mg/kg
Area "B"
Chemicals 0-2 feet below surface
PAHs < 0.46 mg/kg
Aroclor-1260 < or equal to 1 mg/kg
Notes: < less than.
* No risks were associated with lead below the 2 foot level; therefore,
no cleanup was required.
The cleanup of PSC 17 consisted of the removal and transportation of contaminated
soils from the site to an offbase RCRA-permitted disposal facility. PSC 17
required excavation at two locations: Area A and Area B (see Figure 1-3). Soil
samples were collected within the Area A and Area B excavations to confirm
adequate cleanup. Samples were sent to an offsite laboratory for analyses.
Area A. Excavation of the entire Area A (Figure 1-3) initially proceeded to a
depth of 2 feet. Confirmatory samples were then collected around the perimeter
of the excavation to detect any remaining chromium or lead. The cleanup required
further excavation of Area A to a minimum depth of 5 feet. At the eastern end
of Area A, the design required excavation to a depth of 8 feet. Samples
collected below 2 feet were analyzed for total chromium only. Samples were
collected in these deeper areas to ensure that cleanup levels for chromium were
met.
Excavated soils from Area A were transported offbase on a daily basis to Envirite
Corporation of Harvey, Illinois, an RCRA disposal facility. Excavation continued
until confirmatory analysis indicated all target cleanup concentrations were
achieved. A total of 410 tons of contaminated soil was excavated from Area A.
Area B. Cleanup at Area B included removal of visibly stained surface soil from
an area approximately 10 feet in diameter. This area was east of the driveway,
shown on Figure 1-3. These soils (approximately 6 cubic yards) were loaded
directly into a rolloff dumpster. The initial excavation was followed by side
wall confirmatory sampling and analysis of the remaining soil. This procedure
ensured that the target cleanup goals were met.
Laboratory analysis of these confirmatory soil samples indicated that target
cleanup levels were met. The soil from Area B was then tested and approved for
disposal at the Pecan Row Landfill (Valdosta, Georgia).
Site Restoration. Once excavation at PSC 17 was complete, the excavated area was
backfilled and compacted using confirmed clean soil from offsite sources.
Samples of the fill material were collected for laboratory analyses prior to use
at PSC 17 to ensure the soil was clean. Field density tests were performed on

che in-place backfill to verify proper compaction. The area was then graded and
seeded to restore natural conditions.
6.2.3 Final Inspection of Interim Remedial Actions On May 15, 1996, representa-
tives from MCLB, Albany's Resident Officer In Charge of Construction and
Environmental Branch, and ABB-ES conducted a construction file review and site
walkover at PSC 16 and 17. The inspection revealed that all actions had been
satisfactorily completed in accordance with the 1992 Interim ROD and the
Contractor signed a certification statement that construction was done in
accordance with the drawings and specifications. Therefore, the OU 3 remedial
action was approved by the inspectors. The Remedial Action Report (ABB-ES,
1997a) was prepared summarizing the interim remedial actions implemented at OU 3.

7.0 EXPLANATION OF SIGNIFICANT CHANGES
As lead agency, SOUTHNAVFACENGCOM prepared and issued the Proposed Plan for OU 3
on May 5, 1997. This Proposed Plan described the rationale for a final response
of institutional controls at PSC 16 and NFRAP at PSC 17. The GEPD, USEPA, and
public concur with this final response. Therefore, no significant changes were
made to the Proposed Plan. This response action may be reevaluated in the future
if conditions at OU 3 indicate that an unacceptable risk to public health or the
environment would result from exposure to the various media.

COMMUNITY RELATIONS RESPONSIVENESS SUMMARY
1.0 OVERVIEW
Southern Division, Naval Facilities Engineering Command (SOUTHNAVFACENGCOM) held
a public meeting on May 13, 1997, at Marine Corps Logistics Base (MCLB), Albany
to discuss the Proposed Plan for the final institutional controls at Potential
Source of Contamination (PSC) 16 and no further response action planned at PSC
17, and solicit comments and questions from the public. Two citizens attended
this public meeting and expressed an interest in the process and an appreciation
for the work performed by SOUTHNAVFACENGCOM and MCLB, Albany. No written
comments or questions were received from the public.
2.0 BACKGROUND OF COMMUNITY INVOLVEMENT
An active community relations program providing information and soliciting input
has been conducted by MCLB, Albany for the entire National Priority List (NPL)
site. Interviews of citizens onbase and in the city of Albany were conducted in
the winter of 1990 to identify community concerns. No significant concerns that
required focused response were identified. Most comments received were
concerning the potential for contamination of water resources. However, those
interviewed indicated that they place great trust in MCLB, Albany and their
efforts to rectify past waste disposal practices. In addition, the base has
formed a Technical Review Committee (TRC) that includes members representing the
city of Albany, Dougherty County, and the local academic community. These TRC
community members were contacted in July 1996 to determine their continued
interest in serving on the committee. Each member confirmed his or her interest
in serving on the TRC. In addition, parties on the MCLB, Albany Environmental
Branch mailing list were contacted to solicit new community members for the TRC.
Many of these individuals responded enthusiastically, and an information packet
including a TRC application form was prepared and distributed on September 4,
1996. Since this solicitation, the TRC has grown from 10 to 17 members. Since
September 1996, the MCLB, Albany Environmental Branch has held two meetings with
the TRC to update them on the status of the investigation, remediation, and
closure of the 26 PSCs. The local media have also been kept informed since MCLB,
Albany was placed on the NPL. Installation Restoration program fact sheets have
been prepared and made available at the Environmental Office of MCLB, Albany.
Documents concerning OU 3 are located in the Information Repository at Dougherty
County Public Library and the Administrative Record at the Base Environmental
Branch office.

PUBLIC HEARING ON OPERABLE UNIT 3
HELD AT MARINE CORPS LOGISTICS BASE, ALBANY, GEORGIA
ON TUESDAY, MAY 13, 1997 AT 7 P.M.
Lt. Frantz: Now that we've had time to review the posters and read a little bit
about it. we have Esther Hincs, she lives on Base, and Dr. Sykes who works at ASU. At
least we have two this time. I've already told them we haven't ever had two.
I've got a very quick presentation. Basically, the poster session was designed so
people could get familiar with Operable Unit 3 and this 30-minutc meeting is designed for
discussion — discussion of OU3. So I'll go ahead and get started.
First off, I'd like to welcome everybody, bom of you, and I hope the poster session
was worthwhile. I hope it was easy to read. I've got some comments back from Dr. Sykes.
We are lucky Esther is a chemistry major so she didn't have any problem with
polychlorinated biphenyls. But we do appreciate your comments Dr. Sykes — it was just a
little too technical, not bad at all. We'll work on that.
Anyway, we have with us today, in the back of the room. Rob Pope, from USEPA,
and Madeline Kellum, from Georgia Environmental Protection Division. They ensure that we
do things right and protect the environment and restore the environment correctly. That's
what their job is.
We have Joel Sanders, right here, from SOUTHDIV. His job and my job, together.
we're responsible for cleaning up the she and Joel actually handles the money. He's the guy
with the money to pay for the site remediation. In addition we have quite a few ABB
Environmental Services members. ABB is an environmental engineering consultation firm
that we have hired to do the investigations and some of the designs that determine what's
best to do and what's out there. We have Joe Daniel. Jay Peters, Dave Heislein. Brent
Anderson, and Bill Kollar. I think that's everybody. Okay, that's enough for that.
Obviously, the MCLB Installation Restoration Program, our purpose is to restore the
sites that we can as near to natural as they were before they were contaminated by some of
our past operations. The best way for us to do that in the interests of the community is to
involve the community in the decision making process and also to ask for community input.
comments, and discuss their concerns on the proposed plan that we have for Operable Unit
3.
The locations: Operable Unit 3 contains two separate sites. The first one is in the
south central portion of the base, right next to the Chow Hall, the Marine Corps Chow Hall.
It used to be a site where a transformer was sitting on a concrete pad and the transformer
had polychlorinated biphenyls hi it and it leaked a little bit and some of that went into the
soil on the site. So that's where the contamination came from for 16. And PSC 17 is the
southern most portion of the Maintenance Center; and in the Maintenance Center, some of
the activities there in the past have been chrome plating operations and they had a chrome
plating solution spill there which caused the contamination at that site.
-------
In addition to some of tlic previous cleanup actions that arc described in the poster
session, what we are proposing to do at this time in efforts to kind of close out these sites is
we have some restrictions for PSC 16, we call it the final institutional controls. Those
institutional controls include restrictions on the site access, restrictions on any kind of
construction that happens around or on the site, and restrictions on storing anything on the
site that wouldn't be good if that spilled on top of the site. Also, as pan of the site workup,
we put down asphalt to keep rainwater from infiltrating into the ground and we also put a
fence up around the site. So site maintenance and inspection-periodic inspections of the site
to ensure that the asphalt and fencing are still in good condition.
If the base ever changes ownership, we will be required to file deed restrictions with
the local planning officials so that any new owner, non-Federal owner, will know what's at
the site and what he can and cannot do with that site.
And finally, it's actually under another investigation we're doing, but we will be
doing some groundwater monitoring around the site to ensure that the PCB's that were left in
place from about 4 feet to 10 feet — we had to leave some in place and it's explained there
— but the groundwater monitoring will ensure that those PCB's do not migrate, do not move
out; and if they do, we'll know about it and be able to do something about it at that time.
PSC 17, a success story. Our proposed action is no further remedial action and that's
because we removed the contaminants from the site that posed the problem.
Some things to consider that are actually not on the poster boards. And some of them
actually are — I saw that. The proposed plan for Operable Unit 3 addresses surface and
subsurface soils at PSC 16 and 17, because some of the numerous cleanup actions that we've
done to date have already removed or isolated some of that contamination. And the
groundwater at both of these sites, which have not been affected to date, will be monitored
under Operable Unit 6 which is our base groundwater investigation to ensure that it doesn't
migrate and. if it does, or is causing a problem* that we know about and can do something
about it under a groundwater investigation and remedial action.
The risks at those sites arc within USEPA, US Environmental Protection Agency
guidelines, and those guidelines are designed to protect human health and the environment.
Now back to the community involvement that I talked about earlier, it's important that
we have community involvement and the way we try to provide for community involvement
is to have meetings like this and we would like to solicit any of your comments, questions or
concerns. And those can be brought up at tonight's meeting, we have comment sheets over
on the table if you'd rather take it home and think about it and read about it a little bit more
and send your comments in that way; that's perfectly fine. Electronic mail, Internet, the
address that's up there is my Internet address and I'll be glad to field any of your comments
or concerns in that media. Or you can call me at 439-5637 or Regina Hegwood. who is the
civilian who works on base and she's the Public Affairs Officer. She can be reached at 439-
52IS. We have copies of the proposed plan up on the front desk there. You are welcome to
take a look at those. And some of the previous investigation documents that we have had
-------
prepared by ABB Environmental Services are also available at either the Dougherty County
Library or Building SS01, here on base. That's where 1 work and we have a copy of all the
investigation documents that tell how we investigated, when, and what we found. So we do-
we do rely on community involvement and community acceptance of what we propose, so we
would like to receive comments if you have any. All comments will be responded to in
writing, so if you comment to us, we will answer in writing and tell you how we changed or
what we did to incorporate your comments and questions.
With that, I think I'll just—we will be around to answer any questions you may have.
If you have any comments or would just like to discuss something, find out more
information, we'd be glad, all of us that are here would be glad to discuss anything with
you. That's it for the formal presentation. The big deal here was the poster session which
provides most of the information that you might want to consider. The Operable Unit 3
proposed plan is sitting over there, we have copies available. And that contains all the
Information. And if you want all the background information, like I said, that's available at
the public library or in my office. With that, we'll be here to answer questions or discuss.
[No questions were asked during the public hearing. Individuals spoke with both
visitors before they departed.]
The foregoing is an accurate transcript of the public meeting held at Marine Corps
Logistics Base. Albany, Georgia, on Tuesday, 13 May 1997, beginning at 7:10 p.m. and

-------
INSTITUTIONAL CONTROL PLAN FOR PSC 16
Marine Corps Logistics Base
Albany, Georgia
This attachment identifies institutional controls restricting (a) human access
to and contact with subsurface soils contaminated with residual oil and
polychlorinated biphenyls (PCBs) and (b) certain activities occurring on, around,
or under Potential Source of Contamination (PSC) 16 of the Marine Corps Logistics
Base (MCLB) , Albany. A survey plat of PSC 16 (dated August 26, 1996) is
attached.
Background
As a result of previous investigations, MCLB, Albany was placed in Group 7 of the
National Priorities List for Uncontrolled Hazardous Waste Sites, according to
Title 40, Code of Federal Regulations (CFR), Part 300 (40 CFR 300, July 1991).
ABB Environmental Services, Inc. (ABB-ES) , was contracted under the Comprehensive
Long-Term Environmental Action, Navy (CLEAN) contract (contract number N62467-89-
D-0317), to prepare Remedial Investigation and Feasibility Study (RI/FS)
Workplans, Site Screening Workplans, and associated documents for 26 PSCs at
MCLB, Albany. PSC 16, Building 7100 PCB Area, and PSC 17, Depot Maintenance
Activities Chrome Area, comprise Operable Unit (OU) 3 at MCLB, Albany.
An RI/FS was conducted at OU 3 from October 1991 through August 1992. An Interim
Record of Decision (IROD) was signed for OU 3 in August 1992 (MCLB, Albany, 1992)
requiring the construction of a multilayer cap at PSC 16. A remedial action
design document was issued in August 1993 (ABB-ES, 1993) and construction of the
remedy was completed in January 1994. A Remedial Action Report, which documents
the construction of the interim remedial action (ABB-ES, 1997), was completed in
1997.
PSC 16. PSC 16 (Building 7100, Polychlorinated Biphenyl [PCB] Area) is the
former location of an electrical transformer and supporting concrete pad. It is
approximately 12 by 16 feet in size, located on the south side of Building 7100
(see attached survey). During an inspection conducted as part of a PCB
transformer change-out program, evidence of leaking transformer oil was observed
on the concrete pad beneath the transformer. Soil sampling and analysis
conducted in 1990 confirmed the presence of PCBs and semivolatile organic
compounds (SVOCs) in soil beneath the former transformer pad. Contaminated
surface soil was subsequently excavated from a 12-by-16-foot area to an
approximate depth of 44 inches below land surface (bis), disposed of off-base at
a permitted facility, and replaced with certified clean soil. Additional soil
sampling and analysis below the clean backfill identified further soil
contamination of PCBs and SVOCs to a depth of approximately 10 feet bis. These
remaining subsurface soils were found to contain concentrations of PCBs in the
range of 13 to 310 milligrams per kilogram. Other contaminants of concern
included various forms of chlorobenzenes (ABB-ES, 1992).
In accordance with the signed IROD and approved Remedial Action Design, a
multilayer cap was constructed at PSC 16 between November 1993 and January 1994.
Preparatory work prior to construction of the cap at PSC 16 included removal of
approximately 18 inches of existing clean fill, debris, an existing fence, an
electric insulator and frame with posts, and concrete footings from within the

limits of work. The multilayer cap consisted of the following: two inches of
asphalt at the surface supported by 12 inches of drainage sand, a 40-mil thick,
very low density polyethylene liner, and 6 inches of clayey sand base material
on the bottom. A chain-link fence with locking gate and warning signs was also
erected to restrict unauthorized access to the area.
The pavement surface will reduce the infiltration of surface water into the
underlying soil, thereby directing the majority of surface water off the site.
If water infiltrates the pavement, it will be collected on the VLDPE liner. The
liner was sloped away from the building to drain water so as to prevent
infiltration to the contaminated soils below. The liner is also attached to the
adjacent building and sealed to prevent water from leaking through at the
building/liner interface
The objective of the multilayer cap was to (1) provide a barrier to prevent
potential future direct human exposure to contaminated subsurface soils, and (2)
eliminate the direct infiltration of surface water through the contaminated soil
so as to preclude the potential for contaminant migration into groundwater. The
multilayer cap was designed to create a barrier that will have long-term
effectiveness and permanence in accordance with National Oil and Hazardous
Substances Contingency Plan remedy selection criteria.
Land Use Restrictions (Institutional Controls)
The OU 3 IROD (MCLB, Albany, 1992) calls for the implementation of appropriate
land-use restrictions on future activities within the fenced area surrounding
PSC 16. The following institutional controls will restrict future construction
and storage activities and limit physical access to the site while it remains
under the ownership of the Federal government. Should the Navy later decide to
transfer, by deed, ownership in the property encompassing PSC 16 to any private
person or entity, then the provisions of paragraph Deed Covenants and Conveyance
of Title as set forth on page B-3 of this Institution! Control Plan (ICP) shall
apply. Until that time, the following institutional controls will remain in
effect:
MCLB Security. Physical access to the property surrounding PSC 16 is controlled
by base security measures, including fencing, pass and identification procedures,
guardhouse, and periodic security patrols.
PSC 16 Security. Physical access to PSC 16 is controlled by fencing with a
locked gate. Signs are attached to the fence identifying restricted access and
points of contact through which to gain access to the site.
Authorized Activities. The following activities are permissible within the
confines of PSC 16:
(1) Storage of supplies and materials that are nonhazardous and do not
contain oil and/or hazardous materials and do not exceed a bearing
stress of 1,350 pounds per square foot (psf).
(2) Such other activities or uses that will not result in the distur-
bance or penetration of the constructed surface cap and thus will
present no greater risk of harm to health, safety, public welfare,
or the environment than the activities and uses set forth in
ALB-OU3ROD
SAS.O7.97
B-2
-------
paragraph (1) above. Such activities will not be undertaken without
the express concurrence of the appropriate U.S. Environmental
Protection Agency (USEPA) and Georgia Environmental Protection
Division (GEPD) representatives.
i
Unauthorized Activities. Those activities and uses that are inconsistent with
the objectives of this institutional control plan, and which, if implemented at
PSC 16, could pose an increased risk of harm to health, safety, public welfare,
or the environment, are as follows:
(1) Penetration of the surface cap (pavement and flexible membrane
liner);
(2) Installation of subsurface utilities or excavating of any type for
any purpose;
(3) Construction of a belowground structure (including but not limited
to foundation walls, wells fop drinking water, irrigation, or other
domestic purpose);
(4) Installation and/or storage of chemicals, waste chemical products,
or equipment with the potential for chemical leakage;
(5) Storage of consumable goods for human or animal consumption;
(6) Motorized vehicle traffic or parking with a per tire weight
exceeding 1,350 psf; and,
(7) Any improvements or storage that would cause a bearing stress on the
asphalt cover of 1,350 psf or greater.
Required Maintenance. The following maintenance-related measures will be
undertaken to ensure adequate protection of human health and the environment:
(1) The integrity of the surface seal will be inspected on an annual
basis, and any cracks or visual defects in the surface will be
repaired.
(2) The fence surrounding the site and signs restricting access will be
maintained and replaced as necessary.
(3) The gate providing access to the site will be locked at all times
and a set of keys maintained at the MCLB, Albany Environmental
Branch Office, Building 5501.
Proposed Changes in Uses. Any proposed changes in permissible uses at PSC 16
that may result in exposure to soils beneath the flexible membrane liner material
shall be evaluated by a licensed engineering professional, MCLB, Albany
Environmental Branch Office, USEPA Region IV, and GEPD, who shall render an
opinion as to whether or not the proposed changes will present a significant risk
of harm to health, safety, public welfare, or the environment.
Deed Covenants and Conveyance of Title. Should the decision later be made to
transfer ownership of the property encompassing PSC 16 to any private person or
ALB-OU3ROO
SAS.07.97

-------
entity, then the Navy shall either (1) take all actions necessary to remediate
the site to then existing residential cleanup standards prior to effecting such
transfer, or (2) deed record with the Dougherty County Register of Deeds
appropriate restrictive covenants prohibiting future residential usage of the
property or disturbance of the site's surface cap through routine excavation or
building/utility construction, maintenance, or repair activities on or
immediately adjacent to the site. Should the Navy not have the requisite legal
authority to record such deed restrictions, then it shall take all steps
necessary to ensure that the cognizant federal agency with such authority does
so unless the property is remediated to residential standards prior to such
transfer. Should cleanup of the site not be effected to residential standards,
then notification will be given to USEPA Region IV and GEPD at least 30 days
prior to any conveyance of title to the site to any third party(ies), and the
purchaser(s) of the site will be advised via the deed documentation as to then
existing site conditions and any/all associated institutional controls and long-
term monitoring requirements.
Posting. This ICP will be referenced in all MCLB, Albany Utility Maps and in
MCLB, Albany's Master Plan. No maintenance or construction activities are
planned without referring to these maps.
