subject Decision document and concurs with the remedy of Institutional ContrOls-at PSCs 3 and
26 and No Action at PSCs 1 and 2 at Operable Unit 1. This remedy is supported by the
previously completed Remedial Investigation, Feasibility Study and Risk Assessment Reports, as
well as the Removal Action for the sludge piles at PSC 3. The remedy of Institutional Controls
and No Action is protective of human health and the environment
. It is. EPA.'s expectation that PSCs 3 and-26 will be monitored on a regular basis by .the.
MCLB Albany EnvuorimentaT staff to ensure that the institutional controls are in place and being.:
adhered to by the base. On other facilities this, has been done on a quarterly basis and it is '
recommended that MCLB follow Department of the Nayy. guidelines in.conducting such
'
changes in use of either 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 that could impact the areas
encompassed by PSCs 3 and 26 be reviewed by the MCLB Environmental office. These measures
will result in the elimination of any inadvertent noncompliance with the institutional control
requirements.

DECLARATION OF THE
RECORD OF DECISION
SITE NAME AND LOCATION
Marine Corps Logistics Base
Operable Unit One
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) 1 at the Marine Corps Logistics Base (MCLB) , Albany. It was developed
in accordance with the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA) as amended by the Superfund Amendments and Reauthorization
Act, and to the extent practicable, the National 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. Based on the review of this OU 1 ROD and
previous documents, the U.S. Environmental Protection Agency (USEPA) Region IV
and State of Georgia concur with the selected remedies.
ASSESSMENT OF THE SITE
OU 1 consists of four potential sources of contamination (PSC): PSC 1, East
Disposal Area; PSC 2, Rubble Disposal Area; PSC 3, Long-Tenn Landfill; and PSC
26, the Containment Berm Area. PSC 3 is also a solid waste landfill closed under
the State of Georgia Solid Waste regulations in 1988.
A remedial investigation and baseline risk assessment (RI/RA) was conducted at
OU 1 between 1992 and 1995. The baseline RA examined the hypothetical situations
for current land use in which an older child could trespass on OU 1 and a
hypothetical future land use of OU 1, 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 1. The RA evaluated both cancer and noncancer risks. An
ecological RA was also conducted for OU 1.
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 1
indicate that application of the acceptable risk range is appropriate. Site-
specific conditions supporting the use of the risk range include the base
perimeter fence, which restricts public access to surface and subsurface soils,
surface water and sediment at OU 1. For noncancer risks, the similar point of
departure is a hazard index (HI) greater than 1. If the total estimated
noncancer risk exceeds this value, then site-specific conditions and effects from
individual compounds are evaluated to determine if a response is necessary.
-- :
The RA conducted for surface and subsurface soil at PSC 1 resulted in risks
acceptable to the USEPA Region IV for carcinogens (3xlO~7) and noncarcinogens (HI
ALB-OU1.ROD
PMW.08.97 -j-
-------
of 0.24). There was no surface water or sediment present at this site. The RA
for PSC 2 included surface and subsurface soils, surface water and sediment. The
RA results were also acceptable to USEPA Region IV (9xlO~6, HI of 0.50) such that
no treatment, containment or restricted access are required for PSCs 1 and 2.
With the exception of the sludge piles located on the surface of PSC 3, the
cancer (9xlO~6) and noncancer risks (HI of 1) from exposure to surface and
subsurface soil, surface water, and sediment were acceptable to USEPA Region IV.
The sludge piles were found to contain elevated concentrations of inorganic
chemicals posing a potentially unacceptable noncancer risk to the current child
trespasser (HI of 2) and potential future resident (adult and child, HI of 24) .
As a result, the three sludge piles were removed down into the landfill soil
cover and disposed of off-base at a permitted disposal facility in May 1996.
Confirmatory sampling was performed, following removal of the sludge, indicating
elevated inorganic chemical concentrations in the newly exposed landfill soil
cover. Further excavation to remove the contaminated soil would have disturbed
the PSC 3 landfill cover and was not performed. Per GEPD, USEPA Region IV, and
the Navy's concurrence that certified clean fill was placed over the excavated
area, thereby restoring the solid waste landfill soil cover. The disturbed areas
were revegetated with native grass. Because PSC 3 is a former solid waste
landfill, a response action will be implemented to protect the integrity of the
soil cover.
Human health and ecological risks associated with exposure to the surface and
subsurface soils at PSC 26 were evaluated and compared to the cancer and
noncancer risk criteria (1x10"* to IxlO"6, HI greater than 1). Cancer risks
associated with exposure to the surface and subsurface soils were acceptable to
USEPA Region IV (5xlO~5) . Noncancer risks associated with the exposure to
subsurface soils (HI of 0.1) was also acceptable. However, the PSC 26 surface
soil was found to pose a potential noncancer risk (HI of 5) for a future child
resident due to the presence of inorganics. Based on the potential noncancer
risk for a future child resident, a response action at PSC 26 was necessary. No
surface water or sediment was found at PSC 26.
DESCRIPTION OF THE SELECTED REMEDIES
There are six OUs at MCLB, Albany, and OU 1 is the third of the six OUs to have
completed RODs. All three completed RODs for OUs 1, 2, and 3 address surface and
subsurface soil, surface water, and sediment. These media will also be addressed
during the RI/FS for OUs 4 and 5, which will be completed soon. Groundwater will
be addressed under a continuing basewide investigation within OU 6 and is the
principal potential threat remaining at MCLB, Albany. This OU is currently in
the RI phase.
This final response for OU 1 proposes that No Action (NA) be implemented at PSCs
1 and 2. This response does not require any treatment, containment, or land-use
restrictions at these two PSCs. The final response also requires the implementa-
tion and enforcement of land-use restrictions at PSCs 3 and 26 via Institutional
Control Plans (ICPs). These ICPs will be incorporated into MCLB, Albany's Base
Master Plan document. The ICP to protect the integrity of the soil cover at PSC
3 is provided in Appendix B of this ROD. The ICP for PSC 26, which restricts
future residential development and land use of the site, is presented in Appendix
C of this ROD. Under these ICPs, land management activities, such as prescribed
burns to reduce the potential for forest fires and the disposal of organic debris
ALB-OU1.ROD
PMWO897 -|j-
-------
(PSC 3), maintenance of existing utility lines, and other activities required to
ensure adequate protection of human health and the environment will be permitted.
If the property is excessed by the Federal Government, the Navy will pursue deed
restrictions on the areas encompassed by PSC 3 and 26.
STATUTORY DETERMINATIONS
The final response actions proposed for OU 1 address the surface and subsurface
soil, surface water, and sediment. Specifically, the final response for PSCs 1
and 2 is NA because no remedial action is necessary to protect human health or
the environment. A future review of site conditions at PSCs 1 and 2 will not be
required because hazardous substances remaining onsite do not pose an unaccept-
able risk to human health and the environment.
The final response actions for PSCs 3 and 26 requiring the implementation of
land-use restrictions will be protective of human health and the environment.
The response action at PSCs 3 and 26 comply with most Federal and State
requirements that are legally applicable or relevant and appropriate to the
response action, and are cost effective.
Following the Time-Critical Removal of the sludge piles at PSC 3, the remaining
soil, surface water, and sediment do not pose an unacceptable risk according to
USEPA Region IV. However, a response action is still required to protect the
integrity of the soil cover on this former solid waste landfill. A review will
be conducted within 5 years after implementation of the ICP to ensure that the
remedy continues to provide adequate protection of human health and the
environment from the landfill.
The remedy at PSC 26 will allow hazardous substances to remain onsite in PSC 26
surface soils above health-based levels. Therefore, a review will be conducted
within 5 years after commencement of remedial action to ensure that the remedy
continues to provide adequate protection of human health and the environment.

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 recreational open
space. Most of the land to the northwest and west of the base is residential and
commercial.
Operable Unit (OU) 1 is located in the east-central portion of the base, just
inside the northern perimeter along North Shaw road. Figure 1-1 identifies the
location of MCLB, Albany and the approximate location of potential sources of
contamination (PSCs) 1, 2, 3, and 26 that make up OU 1.
1.1 PSC 1. PSC 1, the East Disposal Area, is an inactive landfill approximately
1 acre in size, located adjacent to the western edge of the Indian Lake Wildlife
Refuge Area and south of North Shaw Road (Figure 1-2) . PSC 1 was reportedly used
for the disposal and burning of paper, wood, garbage, solvents, paints, and
thinners in trench-and-fill operations between 1958 and 1959. The area was
subsequently compacted, covered with soil, and planted with pine trees.
1.2 PSC 2. PSC 2, the Rubble Disposal Area, is an inactive disposal area used
between the mid 1950s and 1980. PSC 2 is approximately 7 acres in size and
located due west of the Indian Lake Wildlife Refuge Area and due south of North
Shaw Road (Figure 1-2). This area reportedly received asphalt, concrete, and
other construction debris. There is also the possibility that solvents, paints,
and thinners were discarded in this area. PSC 2 currently has a vegetative cover
consisting of grass, low shrubbery, and pine trees.
1.3 PSC 3 . The Long-Term Landfill is an inactive, 38-acre trench-type disposal
area located approximately due west of the Indian Lake Wildlife Refuge area and
immediately south of North Shaw Road (Figure 1-3) . This area was reportedly used
for the disposal of solvents, paints, thinners, strippers, pesticides, sludges,
polychlorinated biphenyls (PCBs), garbage, and paper between 1954 and 1988. The
landfill was operated from north to south with regular burning until the early
1970s. This landfill was officially closed in 1988 in compliance with the State
of Georgia solid waste regulations. Closure certification required the
installation of a soil cover and the planting of natural vegetation. Three
sludge piles were also located on the surface of the landfill soil cover in the
northeast corner of PSC 3 (Figure 1-3). These sludge piles were removed and
disposed of off-base at a permitted disposal facility under a Time-Critical
Removal Action in May 1996. PSC 3 is currently being used to dispose of organic
debris, such as trees, branches, and grass cuttings.
1.4 PSC 26. The Containment Berm Area is located east of Walker Avenue and
immediately south of North Shaw Road (Figure 1-4), measuring approximately 29
acres in size. Aerial photographs indicate that the surface of this area was
disturbed some time between 1957 and 1964. Three disturbed areas and a berm were
identified in these photographs as shown.on Figure 1-4. The exact construction
and use of the berm at PSC 26 have not been determined. Visual inspection of the
berm indicates that the area may have been used as a disposal area. The area has
not been used since 1964 and has subsequently become overgrown with vegetation.

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 included the 1985 initial
assessment study (IAS), the 1987 confirmation study, and the 1989 Resource
Conservation and Recovery Act (RCRA) facility investigation (RFI). As a result
of these investigations, MCLB, Albany was placed in Group 7 (Hazard Ranking
System score of 45.91 to 43.75) of the National Priority List (NFL) for
Uncontrolled Hazardous Waste Sites (December 1989).
2.1 INITIAL ASSESSMENT STUDY. 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, including PSCs 1, 2, and 3, were evaluated
to determine contaminant characteristics, migration pathways, and potential
receptors. PSC 26 had not yet been identified at the time of the IAS.
The primary pathways identified for migration of contaminants include erosion,
surface water runoff, and groundwater transport. The predominant topographic
slope at OU 1 is to the north, where surface water ultimately discharges to the
Flint River. The predominant direction of regional groundwater flow is west
toward the Flint River, which is located 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. The Confirmation Study was conducted 4by 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
ALB-OU1.ROD
PMW.08.97 2-1
-------
identified as potential threats to human health and the environment (PSCs 9, 10
and 11). PSCs 1, 2, and 3 were included within this Confirmation Study. As
previously stated, PSC 26 had not yet been identified.
The field investigation methodology and analytical results completed during the
Confirmation Study at OU 1 (excluding PSC 26) are summarized below.
2.2.1 PSC 1 Four soil borings were drilled at PSC 1 to total depths ranging
from 35 feet to 60 feet below land surface (bis). Two monitoring wells were
installed in the soil borings.
One groundwater sample and four soil samples were collected for laboratory
analyses. Laboratory analyses included acid and base-neutral extractables,
volatile organic compounds (VOCs), pesticides and polychlorinated biphenyls
(PCBs), selected extraction procedure (EP) toxicity metals, and pH. No
geophysical surveys were conducted, and no surface water or sediment samples were
collected.
Methylene chloride and various metals were detected in two soil samples.
Methylene chloride and phthalate esters are common laboratory contaminants and
sampling artifacts, and EP toxicity metals concentrations were below maximum
contaminant levels (MCLs) as defined by 40 Code of Federal Regulations (CFR) 161.
Trichloroethene (TCE) was detected in groundwater samples from one monitoring
well.
2.2.2 PSC 2 Five soil borings were drilled at PSC 2 to total depths ranging
from 32 feet to 41 feet bis. Two additional soil borings were completed with
hand augers to a depth of 0.5 foot bis. Two monitoring wells were installed in
soil borings. No geophysical surveys were conducted, and no surface water or
sediment samples were collected.
Three soil samples and two groundwater samples were collected for laboratory
analyses. Laboratory analyses included acid and base-neutral extractables, VOCs,
pesticides and PCBs, EP toxicity metals, total organic carbon (TOC), specific
conductance, and pH.
Methylene chloride and various extractables (fluoranthene, benzo[b or kjfluoran-
thene, di-n-butylphthalate, and bis[2-ethylhexyl]phthalate) were detected in two
soil samples. Lead was detected in one soil sample. Methylene chloride and
phthalate esters are common laboratory contaminants and sampling artifacts and
EP toxicity metals concentrations were below MCLs as defined by 40 CFR 161.
2.2.3 PSC 3 Seven soil borings were drilled at PSC 3 to depths ranging from 25
feet to 49 feet bis. Four monitoring wells were installed in soil borings. No
geophysical surveys were conducted, and no surface water samples were collected.
Four soil samples, two sediment samples, and one groundwater sample were
collected for laboratory analyses. Laboratory analyses included acid and base-
neutral extractables, VOCs, pesticides and PCBs, EP toxicity metals, TOC,
specific conductance, and pH.
Methylene chloride was detected in one soil sample and two sediment samples.
Phthalate esters were detected in three soil samples. Lead was detected in two
soil samples and two sediment samples. Chromium, arsenic, and mercury were
ALB-OU1 ROD

detected in two sediment samples. Only one groundwater sample was collected for
analysis; methylene chloride and bis(2-ethylhexyl) phthalate were detected in
this sample. Methylene chloride and phthalate esters are common laboratory
contaminants and sampling artifacts. EP toxicity metals concentrations were
below MCLs as defined by 40 CFR 161.
Based on the Confirmation Study results, additional investigation was recommended
for PSCs 1, 3, 6, 9, and 11.
2.3 RCRA FACILITY INVESTIGATION. 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. The field investigation methodology and analytical results completed
during the RFI at PSCs 1, 2, and 3 are summarized below. PSC 26 had not yet been
identified at the time of the RFI.
2.3.1 PSC 1 During the RFI, three monitoring wells, ranging in depth from 62
feet to 89 feet bis, were installed at PSC 1. Three groundwater samples, one
from each well, were collected for laboratory analyses. No geophysical surveys
were conducted, and no surface water or sediment samples were collected.
Laboratory analytical results for two groundwater samples were below quantitation
limits or below MCLs for metal concentrations. Benzene, chlorobenzene, 1,2-
dichlorobenzene, trans-1,2-dichloroethene (DCE), toluene, TCE, and vinyl chloride
were detected in one groundwater sample.
2.3.2 PSC 2 Four wells, ranging in depth from 93 feet to 109 feet bis, were
installed at PSC 2. Three groundwater samples were collected for laboratory
analyses. No geophysical surveys were conducted, and no surface water or
sediment samples were collected.
Laboratory analytical results for one groundwater sample were below quantitation
limits or below MCLs for metal concentrations. Only VOCs (benzene, trans-DCE,
and TCE) were detected in one groundwater sample.
2.3.3 PSC 3 Seven wells, ranging in depth from 30 feet to 111 feet bis, were
installed at PSC 3. Four groundwater samples were collected for laboratory
analyses. No geophysical surveys were conducted, and no surface water or
sediment samples were collected.
Laboratory analytical results for all samples except one were below quantitation
limits or below MCLs for metal concentrations. Only VOCs (trans-DCE and TCE)
were detected in the groundwater sample from one well.
Of the nine PSCs studied in the RFI, only PSCs 7 and 9 did not require further
investigation. PSC 26 was identified subsequent to this RFI and evaluated during
the remedial investigation and risk assessment (RI/RA) for OU 1.-

2 . 4 REMEDIAL INVESTIGATION/RISK ASSESSMENT. In July 1991, 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 Comprehensive Environmental
Response, Compensation, and Liability Act (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.
Available data on the 24 PSCs were sufficient to indicate the requirement for a
remedial response as described in the NPL 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. PSC 26 was discovered during the remedial investigation
(RI) for PSC 3 as a possible source contributing to the groundwater contamination
present at PSC 3. 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
CERCLA, 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, and similarity of investigative techniques or
potential response actions. OU 1, consisting of PSCs 1, 2, 3, and 26, was
developed due to the close proximity of the four PSCs, contamination at the
sites, and use as former disposal areas by the installation. The final RI/RA
report for OU 1, excluding PSC 26, was released in May 1995. An addendum to this
report, presenting the investigation of PSC 26, was released in May 1997. The
results of the remedial investigations at OU 1 are presented below.
2. A. 1 Scope of RI The RI defined the nature and extent of contamination of
surface and subsurface soil, surface water, and sediment at OU 1. These
investigations were conducted in two phases. The first phase of investigation
included a geophysical survey, soil gas survey, cone penetrometer testing, and
Geoprobe1" investigations. The geophysical survey was used to determine the
vertical and horizontal extent of disposal trenches, locate buried metallic
objects, and identify areas of previously disturbed or excavated soil. The soil
gas survey was used to identify in situ organic vapors of selected volatile
compounds that may have settled into the subsurface soil. The cone penetrometer
test determined the composition and thickness of the clayey layer above the
bedrock limestone. The Geoprobe1" was used to sample and analyze subsurface soil
for contamination from 6 to 26 feet bis.
The second phase of the RI consisted of surface soil sampling (0 to 12 inches
bis), soil borings and subsurface soil sampling (1 to 40 feet bis), and
collection of surface water and sediment samples as available. The objectives
of these activities were to determine if*- contamination exists and to determine
if contaminants have migrated from their original location. Background sampling
was also conducted to provide site-specific data on naturally occurring elements
ALB-OU1 ROD
pMw.oa.97 2-4
-------
in MCLB, Albany soil and organics commonly found along roadsides or in developed
areas. These background samples included random concentrations of pesticide
residue and polyaromatic hydrocarbons from past use, which do not indicate a
potential source of contamination. Analytical results from this RI are presented
in Chapter 5.0 of this Record of Decision (ROD).
PSC 1: One background sample and six surface soil samples were collected at
PSC 1. Twenty-three soil borings, including one background soil boring, were
also completed at PSC 1. Four sediment samples were collected along the south
edge of North Shaw Road near PSC 1. However, because the drainage ditch very
rarely contains water, no surface water samples were collected. Therefore, these
four sediment samples were included in the PSC 1 database as surface soil
samples. Sample locations are shown on Figure 2-1.
PSC 2: One background sample and 14 surface soil samples were collected at PSC
2. One background boring and four soil borings were also completed at PSC 2.
Six sediment samples were collected from the drainage ditch along PSC 2.
However, only the two locations along North Shaw Road contained adequate water
for corresponding surface water samples. The remaining sediment samples were
included in the PSC 2 database as surface soil samples. Sample locations are
shown on Figure 2-2.
PSC 3: One background sample and 14 surface soil samples were collected at PSC
3 (including the sludge pile). One background boring and 11 soil borings were
also completed at FSC 3. Two sediment and surface water samples were collected
from the drainage ditch at PSC 3 along North Shaw Road. Sample locations are
shown on Figure 2-3.
PSC 26: One background sample and 10 surface soil samples were collected at PSC
26. One background boring and 40 soil borings were also completed at PSC 26.
No other samples were collected from PSC 26, due to the absence of surface water
and sediment. Sample locations are shown on Figure 2-4.
Due to the detection of an isolated metallic object just below the surface, soil
excavation was conducted at PSC 26. This resulted in the identification of
assorted metal and burned materials approximately 1 foot bis in the vicinity of
surface soil sample 26SS01 (Figure 2-4). Excavation of the area confirmed the
disposal of miscellaneous debris (e.g., broken glass bottles), but no potential
source of contamination.
Laboratory tests were conducted on samples of surface soil, subsurface soil, and
sediment from OU 1. Analyses were also done on the sludge piles in the northeast
corner of PSC 3 and surface water from PSCs 2 and 3. Samples were analyzed in
onsite labs and in federally approved off-site labs. Samples, with few
exceptions, were analyzed for VOCs, semivolatile organic compounds (SVOCs),
pesticides and PCBs, inorganics, and cyanide.

3.0 HIGHLIGHTS OF COMMUNITY PARTICIPATION
The Proposed Plan for OU 1 recommended No Action (NA) for PSCs 1 and 2, and
Institutional Controls for PSCs 3 and 26. This document was made available to
the public in the Information Repository located at the Dougherty County Public
Library and in the Administrative Record located at the Environmental Branch
Office, Building 5501, MCLB, Albany, Georgia, 31704-1128. The public notice of
the Proposed Plan was published in the Albany Herald on July 18, 1997, and
meeting notices were mailed to the MCLB IR community mailing list. The public
comment period for the Proposed Plan was July 14 to August 12, 1997. A public
meeting was held on August 7, 1997, at the Human Resources Office, Building 3010,
MCLB, Albany. At this meeting, representatives from Southern Division, Naval
Facilities Engineering Command (SOUTHNAVFACENGCOM), MCLB, Albany, USEPA Region

4.0 SCOPE AND ROLE OF THE FINAL RESPONSE AT OU 1
MCLB, Albany contains 26 PSCs. Of these PSCs, 14 required an RI/FS, 10 are in
site screening, and the remaining 2 PSCs are being addressed under RCRA. The 14
PSCs requiring an RI/FS were divided into 5 individual OUs to address surface and
subsurface soil, surface water, and sediment. Basewide groundwater is addressed
as OU 6. The OUs and the PSCs within each OU are listed below along with the
current regulatory status.
OU 1 - composed of PSCs 1, 2, 3, and 26, completed ROD
OU 2 - composed of PSC 2, completed ROD in September 1996
OU 3 - composed of PSCs 16 and 17, completed ROD in August 1997
OU 4 - composed of PSCs 6, 10, 12, 13, and 22, currently in RI phase
OU 5 - composed of PSCs 8 and 14, ROD currently being prepared
OU 6 - basewide groundwater, currently in RI phase
The selected remedy for OU 2 was NA, while individual remedies were selected for
each of the PSCs at OU 3. A cap was placed over the contaminated soils and
Institutional Controls established at PSC 16, while soil excavation and off-site
disposal were required at PSC 17.
The proposed response for OU 1 consists of two remedies: PSCs 1 and 2 are NA, and
PSCs 3 and 26 are Institutional Controls. Under the NA response, no treatment,
containment, or restricted access is required at PSCs 1 and 2 to protect human
health and the environment.
Land-use restrictions will be implemented at PSC 3. The human health and
ecological risk assessment conducted at PSC 3 determined that exposure to the
surface soil, subsurface soil, surface water, and sediment posed an acceptable
risk according to USEPA Region IV for existing or potential future exposure
scenarios. However, Institutional Controls are required to ensure the integrity
of the soil cover on this former solid waste landfill. The Institutional Control
Plan (ICP) for PSC 3 is presented in Appendix B of this ROD and will become part
of MCLB, Albany's Master Plan document. If the property is excessed by the
Federal Government, the Navy will pursue deed restrictions on the areas
encompassed by PSC 3.
Land-use restrictions will be implemented at PSC 26. The human health and
ecological risk assessment conducted at PSC 26 determined that exposure to the
subsurface soil, surface water, and sediment posed an acceptable risk according
to USEPA Region IV for existing or potential future exposure scenarios. However,
the surface soils were found to pose an unacceptable risk to a potential future
resident. Therefore, Institutional Controls are required to restrict potential
future residential development of PSC 26. The ICP for PSC 26 is presented in
Appendix C of this ROD and will also become part of MCLB, Albany's Master Plan
document. If the property is excessed by the Federal Government, the Navy will
pursue deed restrictions on the areas encompassed by PSC 26.
These response actions were 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 1. A more detailed presentation of this information is
available in the two RI/RA reports for OU 1 (ABB-ES, 1995 and 1997a).
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
chalk. 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 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 west 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

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. Baconian's sparrow
(AimophLla 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 boreal is), 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 1 was studied during a remedial
investigation conducted between 1992 and 1995. Potentially hazardous substances
detected at OU 1 and the media affected are listed in tables by PSC and media
sampled and analyzed. Concentrations of analytes detected by laboratory analyses
are reported in micrograms per kilogram (jjg/kg) or milligrams per kilogram
(mg/kg) for soil samples and micrograms per liter (jig/.?) for water samples. For
instance, a concentration of 8,600 mg/kg for iron means that 8,600 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 1. East Disposal Area The source of contaminants at PSC 1 appears to
be the disposal trenches reportedly used during the 1959 and 1960 trench-and-fill
operations. The areal extent of the disposal trenches, as interpreted from
disturbed land surface areas visible on historical aerial photographs, was
further delineated by geophysical surveys and soil gas surveys, and confirmed
by soil borings. One organic contaminant, pentachlorophenol, was detected in the
surface soil at PSC 1, while several organic contaminants were detected in the
subsurface soil, all at low concentrations. The presence of these contaminants
is likely due to the historical disposal of wastes in trenches at PSC 1. Low
concentrations of pesticides were also found in the subsurface soil associated
with the trench disposal areas. Inorganic compounds detected in PSC 1 surface
and subsurface soil were found to be of similar concentrations as the site
background data. Sampling results for surface and subsurface soil are presented
in Tables 5-1 and 5-2, respectively. No other sources or potential sources of
contamination were identified at PSC 1. Groundwater beneath all of OU 1 will be
addressed as part of the ongoing investigation of OU 6.
5. A. 2 PSC 2. Rubble Disposal Area The potential source area at PSC 2 was
determined by the identification of disturbed land surface on aerial photographs.
This trench-and-fill landfill was used for the disposal of construction debris,
consisting primarily of asphalt and concrete rubble. Previous investigations
revealed no significant contamination at PSC 2. During the RI, the area was
screened extensively by geophysical surveys, soil gas surveys, and subsequent
confirmatory sampling. -

SVOCs and pesticides were detected in the surface and subsurface soil in one
isolated area of PSC 2. These compounds have not moved from the site and
typically degrade rapidly. Inorganics detected in the surface and subsurface
soil were similar to site background data. No significant contamination was
detected in the sediment and surface water samples collected at PSC 2. No
analytes were detected that would indicate an ongoing source of contaminants to
the surface and subsurface soil, surface water, and sediment. Sampling results
for surface and subsurface soil, surface water and sediment are presented in
Tables 5-3 through 5-6. No other sources or potential sources of contamination
were identified at PSC 2.
5.4.3 PSC 3. Lone-Term Landfill PSC 3, a former solid waste landfill, was
reportedly used for the disposal of solvents, paints, thinners, strippers,
dichlorodiphenyltrichloroethane, sludges, PCBs, garbage, and paper from 1954 to
1988. Landfill operations included burning of disposal materials until the early
1970s. The landfill was subsequently closed in 1988 in accordance with the State
of Georgia Solid Waste Regulations. Closure included the installation of a soil
cover on the landfill and revegetation. As a result of the landfill operations,
contamination is present in subsurface soil beneath PSC 3. Pesticides and one
PCB detected in the surface and subsurface soil are likely due to historical road
maintenance activities and historical waste disposal activity, respectively.
Surface water and sediment contained the same low concentrations of pesticides,
and PCBs found in the surface soil are likely due to surface water runoff
associated with road maintenance activities. Sampling results for surface and
subsurface soil, surface water, and sediment are presented in Tables 5-7 through
5-10.
Samples from the PSC 3 sludge piles were collected at the surface, in the middle
of the pile, and at the bottom of the pile where the sludge and the landfill
cover meet. Inorganics and PCBs were detected in the sludge, with the highest
concentrations located in the middle of the pile. Analytical results from
sampling the sludge piles in May 1996 are presented in Table 5-11. These data
are similar to the chemicals found in the sludge from the industrial wastewater
treatment plant onbase.
The PSC 3 sludge piles were found to contain elevated concentrations of inorganic
chemicals. Exposure to these chemicals was found to pose unacceptable human
health risks. As a result, the sludge piles were removed under a Time-Critical
Removal Action to eliminate the potential release of contaminants and were
disposed of at a permitted off-site disposal facility in May 1996. Following
removal of the sludge, confirmatory sampling was performed. Confirmatory
sampling results indicated elevated metals concentrations in the newly exposed
landfill soil cover, likely due to leaching from the sludge piles. Further
excavation to remove the contaminated soil would have disturbed the PSC 3
landfill cover. The GEPD, USEPA Region IV, and the Navy agreed to replace the
landfill soil cover. As a result, 16 inches of certified clean fill was placed
over the excavated area, thereby restoring the solid waste landfill soil cover.
The disturbed areas were then revegetated with native grass. The reconstruction
of the landfill soil cover eliminated the surface soil exposure pathway and the
associated human health risks.
5.4.4 PSC 26. Containment Berm Area PSC 26 was discovered dur-ing the field
investigation of PSC 3 as a possible source contributing to the groundwater
contamination present at PSC 3. Aerial photographs indicate that the surface of

this area was disturbed some time between 1957 and 1964. Three disturbed areas
and a berm were identified in the aerial photographs as shown on Figure 1-4. The
exact construction and use of the berm at PSC 26 have not yet been determined.
Visual inspection of the berm indicates the area may have been used as a disposal
area; however, field investigations of this area disclosed no evidence that
chemical wastes were ever disposed of within the berm. The area has not been
used since approximately 1964 and has subsequently become overgrown with
vegetation.
Low concentrations of VOCs, SVOCs, and inorganics were found in both surface and
subsurface soils at PSC 26. The VOCs and SVOCs detected in the surface soil
(26SS01, Figure 2-4) were confirmed through the collection and analysis of a
duplicate surface soil sample (26SS01D). Based on these results, four additional
surface soil samples were collected from locations 10 feet offset from the
original sampling location (26SS07 through 26SS10, Figure 2-4). Analytical
results for this new sampling event found low concentrations of VOCs present
in three of the four offset surface soil samples, while no SVOCs were detected.
Based on these RI results, the VOCs, SVOCs, and inorganics present at PSC 26 are
potentially due to past disposal activities. Pesticides and PCBs were not
detected at PSC 26. Sampling results for surface and subsurface soil are
presented in Tables 5-12 and 5-13, respectively. No surface water or sediment
was found at PSC 26, and no other sources or PSCs were identified at PSC 26.

6.0 SUMMARY OF SITE RISKS AND RESPONSE ACTIONS
The OU 1 RI analytical data were evaluated to determine whether the individual
compounds were site related (i.e., resulting from historical waste disposal
practices) or consistent with base background data. Based on this evaluation,
a list of chemicals of potential concern (CPCs) was developed for each medium
investigated at OU 1. Tables 6-1 through 6-4 present the CPCs for each PSC and
medium. These CPCs were then evaluated within the baseline RA to determine the
need for a response action.
6.1 OU 1 BASELINE RA. An RA was prepared for preexisting conditions (e.g.,
prior to the removal of the sludge piles from PSC 3) at OU 1 in accordance with
the 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 characteriz-
es the potential present and future risks to human health and the environment.
Three factors were considered when evaluating the risks associated with OU 1:
The extent of contamination present at the site and surrounding areas.
The pathways through which people and the environment are or may
potentially be exposed to contaminants at the site.
The potential toxic effects of site contaminants on humans and the
environment.
Exposure pathways considered for the human health portion of the RA include
ingestion, skin contact, and inhalation. These pathways were then applied to a
current land-use scenario in which an older child trespasses on OU 1. A
potential future land use of OU 1 involving residential development and
associated utility construction was also considered.
The ecological portion of the RA assumed that animals would be exposed directly
to surface soil, surface water, and sediment, with additional exposure from
eating other animals and plants that may contain stored contaminants.
The human health portion of 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 1
indicate that application of the acceptable risk range is appropriate. These
conditions include a perimeter fence around the entire installation, restricting
public access to the soil, surface water, and sediment. For noncancer risks, the
similar point of departure is a hazard index (HI) greater than 1. If the total
estimated noncancer risk exceeds one, then site-specific conditions and effects
from individual compounds are evaluated to determine if a response is necessary.
6.1.1 PSCs 1 and 2 Human health and environmental risks associated with the
exposure to surface and subsurface soil Were evaluated in the RA aC PSCs 1 and 2.
The sediment at PSC 1 and sediment and surface water present at PSC 2 did not
contain CPCs requiring risk evaluation. Tables 6-5 and 6-6 present the human

health RA results for each medium and the potential exposure scenario. These
data indicate that risks associated with PSCs 1 and 2 are acceptable to the
USEPA. The ecological portion of the RA (Ecological Risk Assessment [ERA])
indicated that adverse effects for small mammals and birds associated with
exposure to contaminants in surface soil at both PSCs 1 and 2 are possible, but
unlikely. Based on the RA, an NA decision is proposed for PSCs 1 and 2.
6.1.2 PSC 3 The potential risks resulting from exposure to PSC 3 surface and
subsurface soil, surface water, sediment and sludge were calculated for current
and future land-use scenarios. The cancer and noncancer risks for PSC 3 are
summarized in Tables 6-7 and 6-8, respectively. These data indicate that, with
the exception of the PSC 3 sludge piles, risks associated with PSC 3 are deemed
acceptable by USEPA Region IV.
Based on the ERA, no or minimal adverse effects from exposure to either surface
water or sediment by wildlife and plants are anticipated. Elevated risk was
estimated for plants and wildlife from exposure to inorganics in surface soil
(e.g., cadmium, lead, and zinc). However, adverse effects to ecological
receptors from chemicals in PSC 3 surface soil are unlikely given the conserva-
tive assumptions incorporated in the ERA.
The PSC 3 sludge piles were found to contain elevated concentrations of inorganic
chemicals, including cadmium, chromium, lead, mercury, and silver. Exposure to
these chemicals was found to pose unacceptable noncancer risks in both the
current child trespasser and potential future residential land use scenarios.
As a result, the three sludge piles were removed under a Time-Critical Removal
Action down into the landfill soil cover and disposed of at a permitted off-site
disposal facility in May 1996 (ABB-ES, 1997b). Following removal of the sludge,
confirmatory sampling was performed. Confirmatory sampling results indicated
elevated metals concentrations in the newly exposed landfill soil cover, however,
further excavation to remove the contaminated soil would have disturbed the PSC
3 landfill cover. Per GEPD, USEPA Region IV, and the Navy's concurrence,
certified clean fill was placed over the excavated area, thereby restoring the
solid waste landfill soil cover. The disturbed areas were restored and seeded.
The reconstruction of the landfill soil cover eliminated the surface soil
exposure pathway and associated human health risks. Implementation of the Time-
Critical Removal Action at PSC 3 reduced the potential threat to human health and
the environment from the sludge pile.
6.1.3 PSC 26 In the RI/RA, human health and ecological risks associated with
exposure to the contaminated surface and subsurface soils at PSC 26 were
evaluated and compared to risk levels as required by the USEPA. The summary of
cancer and noncancer risks is shown in Table 6-9. Cancer risks associated with
potential exposures to surface and subsurface soil for both current and future
land uses were deemed acceptable by the USEPA. The HI value for the child
trespasser is less than 1 (HI of 0.5) and would not warrant a response. However,
the PSC 26 surface soil was found to pose a potential noncancer risk (HI of 5)
for a future child resident due to the presence of iron and manganese. Based on
this potential noncancer risk for a future child resident, a response action at
PSC 26 is necessary.
The ERA indicated there is little estimated risk of adverse effects to wildlife
at PSC 26 from exposures to inorganics (e.g., aluminum, manganese, and vanadium)
in surface soil. Several inorganic analytes were identified as potentially

causing adverse effects to plants, and no analytes were identified as causing
adverse effects to soil invertebrates. However, because of the conservativeness
of some benchmarks and low magnitude of exceedences, it is unlikely that plants
are at risk from chemical exposure at PSC 26. Based on the results of the OU 1
RA, no response actions are required for PSCs 1 and 2; however, response actions
are required for PSCs 3 and 26. The Rl/RA report (ABB-ES, 1995) and the RI/RA
Addendum (ABB-ES, 1997a) detail the OU 1 RA results. The PSC 3 Removal Action
Report (ABB-ES, 1997b) details the sludge pile removal from PSC 3. All three
documents are available at the MCLB, Albany Environmental Office and Dougherty
County Library.
6.2 APPLICABLE OR RELEVANT AND APPROPRIATE REQUIREMENTS (ARARS) AND REMEDIAL
ALTERNATIVES. A list of ARARs was prepared to determine the appropriate extent
of cleanup for each medium at each PSC and to develop remedial action alterna-
tives. The ARARs, presented in Table 6-10, include both Federal and State
regulations and guidance criteria. The Superfund Amendments and Reauthorization
Act mandate requires that all remedial actions meet ARARs, the NCP, and
associated guidance documents. Preferred SARA remedial actions involve treatment
that permanently and significantly reduces the toxicity, mobility or volume of
the hazardous contaminants.
Following the identification of the ARARs, a list of remedial alternatives was
developed for each PSC and compared to the nine USEPA screening criteria.
6.2.1 PSCs 1 and 2 Remedial alternative identification and screening was not
conducted for PSCs 1 and 2 because the soil, surface water, and sediment at these
sites do not pose an unacceptable threat to human health or the environment. As
a result, an NA remedy was selected for soil, surface water, and sediment at PSCs
1 and 2.
6.2.2 PSC 3 A Time-Critical Removal Action was implemented at PSC 3 in May 1996
to remove contaminated sludge piles from the surface of the former landfill.
This sludge was found to contain elevated concentrations of inorganics that posed
an unacceptable risk to a current child trespasser and a potential future
resident. This removal action reduced the potential threat to. human health and
the environment. However, a response action is still required to protect the
integrity of the soil cover on this former solid waste landfill. Remedial
alternatives may include no action (in accordance with the NCP), land-use
restrictions and limited action, such as fencing and signs around the perimeter
of PSC 3.
6.2.3 PSC 26 Surface soils at PSC 26 were found to pose an unacceptable risk
to a potential future resident due to elevated concentrations of inorganics in
the surface soils. Potential remedial alternatives to reduce this risk are
similar to those considered for PSC 3 - no action, land-use restrictions and
limited action.
6.2.4 Evaluation of Remedial Alternatives The three remedial alternatives under
consideration for PSCs 3 and 26 were evaluated based on seven criteria, in
accordance with USEPA guidance (USEPA, 1988). These criteria are included below.
1. Overall protection of human health and the environment.
2. Compliance with ARARs.

Overall Protection of Human Health and the Environment. The Institutional
Controls and limited action alternatives will provide the necessary protection
for the landfill soil cover at PSC 3 and prevent exposure to the remaining
inorganics present in the surface soils of PSC 26. The NA alternative does not
meet these criteria.
Compliance with ARARs. The surface and subsurface soil, surface water, and
sediment at PSC 3 do not pose an unacceptable risk to human health or the
environment, and treatment is not required; however, the integrity of the
landfill soil cover must be maintained. Therefore, only the Institutional
Controls and limited action alternatives will meet the intent of the ARARs (Table
6-10). The NA alternative will not protect the integrity of the landfill soil
cover. As for PSC 26, none of the alternatives will satisfy all of the ARARs
because no treatment is proposed for the surface soils at PSC 26. However, the
potential unacceptable risk is limited to long-term residential use of the site.
Long-Term Effectiveness and Permanence. The Institutional Controls and limited
action alternatives will provide the long-term protection of the landfill soil
cover at PSC 3 , and reduce exposure of humans to the remaining inorganics present
in the surface soils of PSC 26. The NA alternative will not meet these criteria.
Reduction of Toxicitv. Mobility or Volume. A removal action was already
implemented at PSC 3, eliminating potential mobility of contaminated sludge to
humans and the environment. These criteria then are not directly applicable to
the goal of protecting the landfill soil cover at PSC 3. None of the proposed
remedial alternatives will address the toxicity, mobility or volume of
contaminated surface soil at PSC 26.
Short-Term Effectiveness. Institutional Controls and limited action will be
effective over the short-term in protecting the landfill soil cover at PSC 3 and
restricting residential development and land use of PSC 26. The NA alternative
will not satisfy this criteria.
Implementabi1ity. Institutional Controls can be readily implemented through ICPs
at both PSCs 3 and 26. These plans will become attachments within MCLfi, Albany's
Master Plan and be indicated on all base maps. There is no implementation
required for the NA alternative.
Cost. There are no capital or operational costs associated with the NA and
Institutional Control alternatives. The limited action alternative will require
the installation of a security fence and signs around the perimeter of PSCs 3 and
26. The estimated cost for this fence and signage is approximately $10 per
linear foot. This would result in a capital cost of approximately $70,000 and
$55,000 for PSCs 3 and 26, respectively. Estimated maintenance costs for each
site would be approximately $2,000 per year for the replacement of damaged or
vandalized fencing. This results in a tetal estimated cost of $170,000 for PSC
3 and $115,000 for PSC 26, over a 30-year period.
ALB-001 ROD
PMW.08.97 6-16
-------
The USEPA guidance also requires that the remedial alternatives be evaluated for
regulatory acceptance and public acceptance (total of nine criteria). These
evaluations were addressed through the release of the OU 1 Proposed Plan on
July 14, 1997, and the 30-day public comment period, ending August 12, 1997. No
comments were received from USEPA Region IV, GEPD, or the public during this 30-
day comment period.
6.3 RESPONSE ACTIONS.
6.3.1 PSCs 1 and 2 Based on the results of the RA, an NA decision is proposed
for PSCs 1 and 2. This alternative does not specify any treatment, containment
or land-use restrictions for these PSCs.
6.3.2 PSC 3 Based on the identification and evaluation of remedial alternatives
presented in Subsection 6.2.3, Institutional Controls will be implemented at PSC
3, the Former Solid Waste Landfill, to protect the integrity of the existing soil
cover. Under this ICP, land management activities, such as prescribed burns to
reduce the potential for forest fires and the disposal of organic debris,
maintenance of existing utility lines will be permitted. Other activities
required to ensure adequate protection of human health and the environment may
still be conducted at PSC 3. The ICP for PSC 3, provided in Appendix B of this
ROD, will be implemented into daily operations of the base through its insertion
into the MCLB, Albany Base Master Plan. A review will be conducted within 5
years after implementation of the ICP to ensure that the remedy continues to
provide adequate protection of human health and the environment from the
landfill.
6.3.3 FSC 26 The noncancer risk (HI of 5) associated with the future child
resident exceeded the USEPA point of departure (HI greater than 1) thereby
requiring a response action. As a result of the remedial alternative evaluation,
Institutional Controls will be implemented at PSC 26 restricting future
residential development and land use of the site (see Appendix C). Land
management practices such as maintenance of animal food plots or prescribed
burning for fire prevention are allowed under the ICP for PSC 26. A review will
be conducted within 5 years after commencement of remedial action to ensure that
the remedy continues to provide adequate protection of human health and the
environment. Other activities required to ensure adequate protection of human
health and the environment may still be conducted at PSC 26 under this ICP.

7.0 EXPLANATION OF SIGNIFICANT CHANGES
As lead agency, SOUTHNAVFACENGCOM prepared and issued the Proposed Plan for OU 1
on July 14, 1997. This Proposed Plan described the rationale for a final
response of NA at PSCs 1 and 2, and Institutional Controls at PSCs 3 and 26. The
GEPD, USEPA Region IV, 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 1 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 August 7, 1997, at MCLB, Albany to discuss the Proposed Plan
for No Action at PSCs 1 and 2, and Institutional Controls at PSCs 3 and 26 and
solicit comments and questions from the public. The meeting was advertised in
the Albany Herald on July 18, 1997, and meeting notices were mailed to the MCLB
IR community mailing list. 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 during the 30-day comment period.
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.
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 1 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 1
HELD AT MARINE CORPS LOGISTICS BASE, ALBANY, GEORGIA
ON THURSDAY, AUGUST 7, 1997 AT 7 P.M.
Lt. Frantz: Tonight, we're here to talk about Operable Unit 1 and the base's
proposed plan which we will discuss during this public meeting. And the proposed plan is
basically what we propose to do with the sites which we feel are protective of human health
and the environment.
I would like to welcome everybody on behalf of the cleanup and investigation team as
well as the Commanding General of our base, Major General Gary S. McKissock. We do
have I think we have already made introductions, but we have Mr. Robert Pope from
U.S. EPA, Madeleine Kellam and Billy Hendricks from Georgia Environmental Protection
Division, Joel Sanders from Southern Division, Naval Facilities Engineering Command. Joel
and myself are pretty well in charge of~or responsible for the actions taken at the base and
working with the contractors to figure out what's wrong and what we need to do to fix it.
We also have with us tonight Jerry Palmer, he is the head of the Environmental Branch on
Base, and myself, I'm Alan Frantz. I work at the Environmental Branch. We also have with
us some of our contracted help; they are engineers, scientists, geologists with ABB
Environmental Services, and we have hired these folks to help us characterize the area, the
contamination and try to figure out what we need to do to protect human health and the
environment. If there are any questions or comments or concerns of any kind, please stop me
and we'll discuss them at that time.
The objective of tonight's meeting is to review Operable Unit 1, and the histories of
each of the sites that make up Operable Unit 1 of which there are 4 operable units-or PSC's
Potential Source of Contamination 1, 2, 3, and 26. We are going to present the proposed
actions we have for each of those sites and we want to get community input on the proposed
plan.
Going into the sites themselves, first we have a map of the general location on base
where they occurred. Potential Source of Contamination 1 is called our East disposal area. I
will discuss the areas themselves in a further slide. PSC 2 is a rubble disposal area. PSC was
a 38 acre landfill, and PSC 26 is what we call the containment berm area.
Actually, I'm going to go ahead and go over what the sites actually were. PSC 1, the
East disposal area, was used for about two years, from approximately 1958 to 1959. The
area was used reportedly received paper, wood, garbage, solvents, paints and thinners.
PSC 2, the rubble area rubble disposal area received surface deposits of, generally,
construction debris but it was also reported that thinners, paint solvents, were disposed of at
that site also. It is a seven-acre site. The long term landfill, PSC 3, was a trench and fill type
landfill used from about '54 to 1988. It received solid waste, municipal waste, solvents,
paints, thinners, and other chemicals, including polychlorinated biphenyls. PSC 26,
containment berm area, approximately 29 acres in size. We don't have any clear records
indicating what the area was actually used for, but the area was investigated because of some .
-------
bermed in areas that looked like things had been disposed there and we'll talk about what
was found in those areas when we get into the discussion of the findings.
The East disposal area, again, was the one-acre landfill only used for two years. Or
one acre disposal area. What we found there were small amounts of organic and inorganic
chemicals including pesticides and those were found in surface and subsurface soil. The
inorganic chemicals were found to be very similar to background amounts. That means
inorganic chemicals are generally naturally occurring if they are similar to background, so in
this area, the inorganic chemicals were found to be similar to the background, which is areas
that have not been subject to any kind of contamination. Also found in the area were
organics and pesticides and they were found in concentrations that presented no unacceptable
risks to human health and the environment. And again, we are talking about, in this area,
only surface and subsurface soils were sampled because there were no surface water or
sediment areas found on that cite.
Potential Source of Contamination 2, the rubble disposal area. Once again, same as
PSC 1, organic and inorganic chemicals and pesticides were found in both the surface and
subsurface soils. And again, exactly the same as PSC 1, the inorganic chemicals were very
similar to background amounts; the organics and pesticides were found in concentrations that
did not present an unacceptable risk.
Potential Source of Contamination 3, the long term landfill. In the surface soils there
were small amounts of, again, organic and inorganic chemicals, pesticides and one hit of
polychlorinated biphenyl. In the subsurface soil, surface water, and sediment, pesticides and
PCB's were found in these media. At the site, with the exception of a sludge pile, which I
will discuss later, the contaminates were found all the contaminates were found in
concentrations that presented no unacceptable risk to human health and the environment. As I
said, I'll talk about the removal of the sledge piles later and also due to the nature of this
area being a landfill, we will impose future land use restrictions to protect the cap and cover
and the contents within the landfill.
Potential Source of Contamination 26, the containment berm area. Small amounts of
organic and inorganic chemicals were again found in surface and subsurface soils. There
were no surface waters and sediment areas at PSC 26. The organic chemicals at the site were
found in concentrations that posed no unacceptable threat to human health or the
environment, but the inorganics, particularly iron and manganese, proposed a threat to
possible future child residences. Therefore, we are going to propose a response action
tonight.
Before I get into the actions that we are actually going to propose, we will talk about
some of the completed actions that we have done at Operable Unit 1. We did a sludge pile
removal at PSC 3. [After focusing the projector.] The sludge piles that we found here, the
contents of those sludge piles looked and tested out to probably have come from our
industrial wastewater treatment plant at one point. They were like very high in metals, at
least PCB's and the piles themselves did present a health risk, so they were removed and the
contentsor the soil that was removed from that area, contaminated soil, was deposited in a
-------
landfill permitted and built specifically to receive hazard waste. We have talked about or I
will talk about how this proposed plan is only for the surface media surface and
subsurface soils, surface water and sediment. Some of the things that we have done under
Operable Unit 1 are we have a temporary groundwater treatment system at PSC 3 and a
containment system that is continuing to operate at this time. And we also did some
treatability studies at PSC 1 where we tried different methods of groundwater treatment to
see which one would be the bestmost efficient, and would do the best job. Again, I will get
into the groundwater portion in a little bit. But those are some of the actions that we've taken
in Operable Unit 1 to make the areas less risky to human health and the environment.
What are we proposing tonight? For PSC's 1 and 2, since the risk assessment findings
were within ranges that were protective of human health and the environment, we propose no
action. No action response, which means there will be no further land use restrictions, no
cleanups necessary. No action is basically what it means. And that is for the East disposal
area and the rubble disposal area.
PSC 3, a little different story. What we propose tonight is institutional controls and
possible future deed restrictions. Why? Since PSC 3 was a landfill, we need to protect the
area from activities that would disturb the soil cover or the contents of the landfill. Also,
specific land use will be restricted; there will be no below ground structures to include wells,
utilities, or extend walls of buildings, etc., basements. No business, industrial or residential
facilities will be built at this site and no storage of chemicals will be allowed on the site at
any time. There will also be specific actions in the event ownership changes. Should the
ownership of this tract of land or the base change, we will register with the Dougherty
County Registrar of Deeds deed restrictions, deed covenants. This will ensure future property
owners know what is on the land that they now own and some of the actions that are
prohibited, similar to the land use restrictions that we have for ourselves so that somebody
else will not perform any actions that endanger human health or the environment. And any
proposed land use changes will have to be scheduled through the Georgia Environmental
Protection Division.
Potential Source of Contamination 26 we have a similar situation. We have
institutional controls and possible future deed restrictions. And the reason why is a little bit
different than PSC 3. The area as it is now, because of the iron and the manganese, is not
suitable for future residential development. So measures have to be taken to prevent this
from happening. Similar to PSC 3, there will be no below ground construction, no chemical
storage at this area. And again, specific actions will be taken in the event of ownership
change change in ownership of the land. If the base should ever excess this land, the
Dougherty County Registrar of Deed will add deed restriction and restrictive covenants to the
new landowner so that they do not perform any actions in the future that might specifically,
building of residential housing because of the risks at the site from the iron and manganese.
So in summary, PSC's 1 and 2, there will be no action. At PSC's 3 and 26, we'll
have institutional controls and those institutional controls differ a little because of the reason
why the institutional controls are going to be instigated. But they both will have the same
type of deed restrictions necessary if the land should change ownership. If the land doesn't
-------
change ownership, the institutional controls mean that the base will pay particular attention to
land use and what actions are done on those areas to protect us.
Mr. Collins, we do have copies of these slides, too, if you'd like a copy of all our
stuff. We'll get with later, later; and Mr. Freeman.
Some of the things that need to be considered, again, this proposed plan only
addresses the soil, subsurface soil, surface water and sediment. Those are the things not
inclusive of groundwater, that the proposed actions we have for this sites and the ROD will
be based upon, protecting these media vice the groundwater media which we groundwater
is to be addressed in a separate base wide study. We have Operable Unit 6 now; Operable
Unit 6 is dedicated solely to the investigation of basewide groundwater; tracking were the
contaminants are, how fast they are going, when they are going to reach a point where there
might be a problem; et cetera. So again, we are just talking about surface soil, subsurface
soil, surface water and sediment.
Numerous cleanup actions and safety measures have been or, under this proposed
plan, will be taken to address the risks that exceed U.S. Environmental Protection Agency
guidelines. Those-basically it boils down to PSC 26 and the inorganics, iron and manganese.
The protective actions taken for PSC 3 are for different reasons.
Our last slide the reason we have a public meeting and have a public comment
period is because community involvement is important. If there are any comments, they may
be discussed at tonight's meeting, by regular mail, we have comments sheets on the table
over here if you would like to go home and think about it, think about any questions you
may have. You may take it home, right it in and send it to us. If you have got electronic
mail, my electronic mail address is up here; you can send your questions by E-mail. Or they
can be either phoned in to Regina Hegwood at 439-5215. She's the Public Affairs Officer
here at the base. She does most of the public/base interfacing. But if you'd like to call
myself directly at 439-5637, that would be perfectly OK too.
The proposed plan, we have several copies of it here tonight, and other site
documents, such as remedial investigation, risk assessment, these are significantly bulkier
documents. They contain all the information about the sites and the investigations that we
have performed to determine what we wanted to do today; what we are proposing. That is
the backup information for our proposed plan. And they are available for review at the
Dougherty County Library, in the reference section, or in my office. I have the
administrative record at my office on base. Just come in and we have a copy of all those
backup documents here also.
That is basically it for the presentation portion. If you haven't had a chance to look at
the poster section, it has more information that you can digest and if you have any questions,
comments, or concerns, we can discuss them after you've had this chance. We will be
around here tonight as long as it takes to answer any questions or discuss anything you'd like
to discuss about the site.
-------
The public comment period is July 14 through August 12. So it is next Tuesday and
comments again, may be submitted in any of these forms. Or you may come to my office
and talk directly to myself or my boss, Jerry Palmer. That would be perfectly acceptable. Is
there any question, any comments, any type of concerns you might have, feel free to contact
us or one of the people from the Environmental Protection Division or EPA.
[No questions were asked during the public hearing. Individuals spoke with the
visitors before they departed.]
The foregoing is an accurate transcript of the public meeting held at Marine Corps
Logistics Base, Albany, Georgia, on Thursday, 7 August 1997, beginning at 7:10 p.m. and

INSTITUTIONAL CONTROL PLAN FOR PSC 3
Marine Corps Logistics Base
Albany, Georgia
This attachment identifies Institutional Controls restricting (a) human access
to and contact with subsurface soils within the former solid waste landfill, and
(b) certain activities occurring on, around, or under Potential Source of
Contamination (PSC) 3 of the Marine Corps Logistics Base (MCLB), Albany. Figure
B-l presents the general configuration of PSC 3 within MCLB, Albany.
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 contract (contract number N62467-89-D-0317) ,
to prepare and execute Remedial Investigation and Feasibility Study Workplans,
Site Screening Workplans, and associated documents for 26 PSCs at MCLB, Albany.
PSC 1 (East Disposal Area), PSC 2 (Rubble Disposal Area), PSC 3 (Long-Term
Landfill) and PSC 26 (Containment Berm Area) comprise Operable Unit (OU) 1 at
MCLB, Albany.
A remedial investigation/risk assessment (RI/RA) was conducted at OU 1 from March
1992 through June 1995. The public health and ecological RA determined that
exposure to surface and subsurface soils, surface water and sediment at PSC 3
posed an acceptable risk according to the U.S. Environmental Protection Agency
(USEPA) Region IV for existing or potential future exposure scenarios (ABB-ES,
1995); however, Institutional Controls are required by USEPA Region IV and
Georgia Environmental Protection Division (GEPD) to ensure that the integrity of
the soil cover on the former solid waste landfill is not disturbed. Land
management activities, such as prescribed burns to reduce the potential for
forest fires and the disposal of organic debris, will continue to be permitted.
PSC 3. The Long-Term Landfill is a 38-acre trench-type disposal area located
approximately 2,800 feet due west of the Indian Lake Refuge area and immediately
south of North Shaw Road (Figure B-l). This area was reportedly used for the
disposal of solvents, paints, thinners, strippers, pesticides, sludges,
polychlorinated biphenyls (PCBs), garbage and paper between 1954 and 1988. The
landfill was operated from north to south with regular burning until the early
1970s. This landfill was officially closed in 1988 in compliance with the State
of Georgia solid waste regulations. Closure certification required the installa-
tion of a soil cover and the planting of natural vegetation. Three sludge piles
were also located on the surface of the soil cover in the northeast corner of
PSC 3 (Figure B-l). These sludge piles were removed and disposed of off-base at
a permitted disposal facility under a Time-Critical Removal Action in May 1996.
PSC 3 is currently being used to dispose of organic debris, such as trees,
branches and grass cuttings.
The RI confirmed the presence of low concentrations of volatile organic
compounds, semivolatile organic compounds, and inorganics in both the surface and
subsurface soils at PSC 3. The concentrations of these compounds were consistent
with background levels detected at PSC 3 (ABB-ES, 1995). Low concentrations of

pesticides and PCBs detected in the surface and subsurface soil, surface water
and sediment are likely related to historical road maintenance practices and not
due to historical disposal practices.
These RI data were evaluated to determine whether the substances found onsite
occur naturally or resulted from past waste disposal. Based on this evaluation,
a list of chemicals of potential concern (CPCs) was developed for each
environmental medium (e.g., surface soil) sampled at OU 1. An RA was then
prepared in accordance with USEPA Risk Assessment Guidance. This guidance
reflects a conservative approach to RA to ensure that subsequent cleanup
decisions are protective of human health and the environment. Exposure pathways
to these CPCs evaluated within the RA included a current land-use scenario in
which an older child trespasses as well as future residential development and
associated utility construction on OU 1.
Human health and environmental risks associated with exposure to surface and
subsurface soil, surface water, and sediment at PSC 3 were found to be acceptable
by the USEPA Region IV. However, Institutional Controls will be implemented at
PSC 3, as defined on Figure B-l, to maintain the soil cover on the former solid
waste landfill.
Land-Use Restrictions (Institutional Controls)
The OU 1 Record of Decision calls for the implementation and continued
application of appropriate restrictions on future usage of the property
encompassing PSC 3 while it is owned by the Federal government. These
restrictions will apply until/unless site remediation is conducted to restore the
site for unrestricted use. Should the Navy later decide to transfer, by deed,
ownership in the property encompassing PSC 3 to any private person or entity,
then the provisions of paragraph Deed Covenants and Conveyance of Title as set
forth on page B-4 of this Institutional 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 3 is controlled
by base security measures, including fencing, pass and identification procedures,
guardhouse, and periodic security patrols.
Authorized Activities. The following activities are permissible within the
confines of PSC 3:
land management activities, such as prescribed burns to reduce the
potential for forest fires and the disposal of organic debris;
maintenance of existing utility lines; and
such activities or uses that will not disturb the integrity of the
landfill soil cover, unless such other activities are required to
ensure adequate protection of human health and the environment.
Unauthorized Activities. Those activities and uses that are inconsistent with
the objectives of this ICP, and which, if implemented at PSC 3, could pose an
increased risk of harm to health, safety, public welfare, or the environment may
not be conducted at PSC 3. The following activities are not permissible within
the confines of PSC 3:

installation and/or storage of chemicals, waste chemical products, or
equipment with the potential for chemical leakage; and,
such activities or uses not specifically stated under "authorized
activities" listed above that will disturb the integrity of the
landfill soil cover.
Proposed Changes in Uses. Any proposed changes in permissible uses at PSC 3 that
may disturb the integrity of the cover on the former solid waste landfill shall
be evaluated by a licensed engineering professional and MCLB, Albany Environmen-
tal Branch Office to determine whether or not the proposed changes will present
a significant risk of harm to health, safety, public welfare, or the environment.
Any changes in use of PSC 3 are subject to approval by USEPA Region IV and GEPD.
Deed Covenants and Conveyance of Title. Should the decision later be made to
transfer ownership of the property encompassing PSC 3 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 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 documents.

INSTITUTIONAL CONTROL PLAN FOR PSC 26
Marine Corps Logistics Base
Albany, Georgia
This attachment identifies Institutional Controls restricting (a) human access
to and contact with surface and subsurface soils contaminated with inorganic
constituents through residential development of the site and (b) certain
activities occurring on, around, or under Potential Source of Contamination (PSC)
26 of the Marine Corps Logistics Base (MCLB), Albany. Figure C-l presents the
general configuration of PSC 26 within MCLB, Albany.
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 contract (contract number N62467-89-D-0317) ,
to prepare and execute Remedial Investigation and Feasibility Study Workplans,
Site Screening Workplans, and associated documents for 26 PSCs at MCLB, Albany.
PSC 1 (East Disposal Area), PSC 2 (Rubble Disposal Area), PSC 3 (Long-Term
Landfill) and PSC 26 (Containment Berm Area) comprise Operable Unit (OU) 1 at
MCLB, Albany.
A remedial investigation/risk assessment (RI/RA) was conducted at OU 1 from March
1992 through June 1995. The public health and ecological RA determined that the
subsurface soils at PSC 26 pose an acceptable risk according to the U.S.
Environmental Protection Agency (USEPA) Region IV. However, the surface soils
at PSC 26 pose a potential noncancer risk to a future resident above USEPA
criteria (ABB-ES, 1997). No surface water or sediment were present at PSC 26.
Based on the results of the RA, USEPA Region IV and the Georgia Environmental
Protection Division (GEPD) required the implementation of Institutional Controls
to restrict potential future residential development of PSC 26. Land management
activities, such as prescribed burns to reduce the potential for forest fires,
will continue to be permitted.
PSC 26. The Containment Berm Area, measuring approximately 900 feet by
1,400 feet, is located approximately 1,000 feet east of Walker Avenue and
immediately south of North Shaw Road (Figure C-l). Aerial photographs indicate
that the surface of this area was disturbed some time between 1957 and 1964.
Three disturbed areas and a berm were identified in the aerial photographs as
shown on Figure C-l. The exact construction and use of the berm at PSC 26 have
not been determined. Visual inspection of the berm indicates that the area may
have been used as a disposal area; however, field investigations of this area
disclosed no evidence that chemical wastes were ever disposed of within the berm.
The area has not been used since approximately 1964 and has subsequently become
overgrown with vegetation. Prescribed burning of brush is routinely performed
by MCLB, Albany at PSC 26. In 1994, timber was harvested at PSC 26. This is
done periodically to limit the potential for a forest fire.
The RI confirmed the presence of low concentrations of volatile organic
compounds, semivolatile organic compounds, and inorganics in both the surface and

subsurface soils at PSC 26. These compounds are possibly associated with past
disposal activities (ABB-ES, 1997)
These RI data were evaluated to determine whether the substances found onsite
occur naturally or resulted from past waste disposal. Based on this evaluation,
a list of chemicals of potential concern (CPCs) was developed for each
environmental medium (e.g., surface soil) sampled at OU 1. An RA was then
prepared in accordance with USEPA Risk Assessment Guidance. This guidance
reflects a conservative approach to RA to ensure that subsequent cleanup
decisions are protective of human health and the environment. Exposure pathways
to these CPCs evaluated within the RA included a current land-use scenario in
which an older child trespasses as well as future residential development and
associated utility construction on OU 1.
Human health and environmental risks associated with exposure to surface and
subsurface soil were evaluated in the RA for PSC 26. These estimated risks were
deemed acceptable by the USEPA except for the potential, future child resident
land-use scenario. The noncancer hazard index (HI of 5) exceeded the USEPA point
of departure (HI greater than 1) thereby requiring an appropriate human health-
based exposure restriction in this particular case. The elevated HI was due to
the presence of inorganics in the surface soils, primarily iron and manganese.
Therefore, USEPA Region IV and Georgia Environmental Protection Division (GEPD)
required Institutional Controls be implemented that restrict future residential
development and land use of PSC 26, as defined on Figure C-l.
Land-Use Restrictions (Institutional Controls)
The OU 1 Record of Decision calls for the initial implementation and continued
application of appropriate restrictions on future usage of the property
encompassing PSC 26 while it is owned by the Federal government. These
restrictions will apply until/unless site remediation is conducted to restore the
site for unrestricted use. Should the Navy later decide to transfer, by deed,
ownership in the property encompassing PSC 26 to any private person or entity,
then the provisions of paragraph Deed Covenants and Conveyance of Title as set
forth on page C-4 of this Institutional Control Plan (ICP) shall apply. Until
that time, the Institutional Controls listed below will remain in effect.
MCLB Security. Physical access to the property surrounding PSC 26 is controlled
by base security measures, including fencing, pass and identification procedures,
guardhouse, and periodic security patrols.
Authorized Activities. The following activities are permissible within the
confines of PSC 26:
land management activities, such as prescribed burns to reduce the
potential for forest fires;
such activities or uses that will not result in the development of the
site for residential purposes or pose a continuous, long-term exposure
to child residents located near the site, and thus will present no
greater risk of harm to health, safety, public welfare, or the environ-
ment ; and

such activities required to ensure adequate protection of human health
and the environment.
Unauthorized Activities. Those activities and uses that are inconsistent with
the objectives of this ICP, and which, if implemented at PSC 26, could pose an
increased risk of harm to health, safety, public welfare, or the environment may
not be conducted at PSC 26. The following activities are not permissible with
the confines of PSC 26:
construction of a belowground structure (including but not limited to
foundation walls, wells for drinking water, irrigation, or other
domestic purpose);
construction of facilities specifically intended for use as residential
housing;
installation and/or storage of chemicals, waste chemical products, or
equipment with the potential for chemical leakage; and
such activities or uses not specifically stated under "authorized
activities" listed above that will result in the development of the
site for residential purposes or pose a continuous, long-term exposure
to child residents located near the site.
Proposed Changes in Uses. Any proposed changes in permissible uses at PSC 26
that may result in the development of PSC 26 for residential use shall be
evaluated by a licensed engineering professional, and MCLB, Albany Environmental
Branch Office to determine whether or not the proposed changes will present a
significant risk of harm to health, safety, public welfare, or the environment.
Any such changes in use of the site are subject to approval by USEPA Region IV
and GEPD.
Deed Covenants and Conveyance of Title. Should the decision later be made to
transfer ownership of the property encompassing PSC 26 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 soil through routine excavation or

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
