I. Introduction

A. Facility Name

The United States Environmental Protection Agency (EPA) prepared this Statement
of Basis (SB) for the United States General Services Administration (GSA), Southeast Federal
Center (the Facility or Site), Parcel P site located within the SEFC at 1st and M Street, SE,
Washington, D.C. 20507 (hereinafter referred to as Parcel P).

Parcel P is subject to the Corrective Action program under the Solid Waste Disposal Act,
as amended by the Resource Conservation and Recovery Act (RCRA) of 1976, and the
Hazardous and Solid Waste Amendments (HSWA) of 1984, 42 U.S.C. §§ 6901, et seq. The

1

-------
Corrective Action program is designed to ensure that certain facilities have investigated and
addressed any releases of hazardous waste and hazardous constituents that have occurred at their
property.

Information on the Corrective Action program as well as a fact sheet for the Facility, is
available at http://www.epa.gov/reg3wcmd/correc1iveac1ion.h1m.

After reviewing all available data concerning Parcel P, EPA has determined that no
additional characterization or remediation is necessary to satisfy RCRA Corrective Action
obligations. Based on its review, EPA has selected its proposed final remedy for Parcel P and is
now proceeding with its remedy selection process, including providing opportunity for public
comment and review.

B.	Proposed Remedy

This SB explains EPA's proposed remedy that no further actions to remediate soil or
groundwater are necessary given the planned land use at Parcel P. EPA's proposed remedy is to
require the owner of Parcel P to develop and maintain certain property restrictions known as
Institutional Controls (ICs). The proposed ICs are detailed in Section V, below. These controls
will provide assurance that the land use, as anticipated when the remedy was proposed, does not
change. EPA's proposed remedy represents "Collective Action Complete with Controls" as
described in EPA Guidance found in the Federal Register / Vol. 68, No. 37 / Tuesday, February
25, 2003 / Notices [FRJL - 7454-7] pages 8757 to 8764.

Til is SB summarizes information contained in the work plans and reports reviewed by
EPA and included in the Administrative Record (AR).

C.	Importance of Public Input

Before EPA makes a final decision on its proposal for Parcel P, the public may
participate in the remedy selection process by reviewing this SB and documents contained in the
AR for Parcel P. The AR contains the complete set of reports that document Facility conditions,
including a map of Parcel P, in support of EPA's proposed remedy. EPA encourages anyone
interested to review the AR. The AR is available for public review at the EPA Region III office,
the address of which is provided in Section VIII, below.

EPA will address all significant comments received during the public comment period. If
EPA determines that new information or public comments warrant a modification to the
proposed remedy, EPA will modify the proposed remedy or select other alternatives based on
such new information and/or public comments. EPA will approve its final decision in a
document entitled the Final Decision and Response to Comments (FDRTC).

II. Facility Background

Parcel P is located at 1st and M Street, SE, Washington, D.C. 20507. Parcel P occupies
approximately 5 acres along the southern end of the Facility (Attachment 1). Parcel P is bordered
by the future Water Street, SE and future River Street, SE to the north; by the Washington Navy

2

-------
Yard to the east; by the Anacostia River to the south; and by 2nd Street, SE to the west
(Attachment 2).

Parcel P contains a seawall, a small concrete pier, and Building 173 (the Lumber Storage
Shed, a historical building that is being renovated). Parcel P is being developed into a waterfront
park. Two new single-story slab on grade buildings, Buildings P2 and P3, will be constructed for
retail use and will be located east and southeast of Building 173, respectively. Building 173 was
originally constructed in 1919 and used for storage of building maintenance materials. A seawall
along the Anacostia River was replaced by anew concrete seawall in 1999. A small concrete
pier southwest of Building 173 was also constructed at that time. A significant amount of soil
and fill material was removed during seawall construction and replaced with uncontaminated
material from off-site sources.

Four other buildings were formerly located on Parcel P: the southern portion of Building
158 (the Brass Foundry), Building 159E (the General Machine Annex), Building 187 (the Brass
Smelter), and Building 204 (the Screen House). Hazardous wastes were removed from these
buildings and they were demolished in 1998.

An Interim Measures Work Plan for Parcel P (IM Work Plan) was submitted to and
approved by EPA in 2008. The IM Work Plan described the proposed remediation of
contaminated soil on Parcel P. The latest investigations and cleanup were conducted in
accordance with the EPA-approved IM Work Plan. Upon completion of the cleanup, GSA
reported the activities and results to EPA in the Interim Measures Completion Report for Parcel
P dated April 16, 2010 (Completion Report).

Parcel P is part of the 42-acre SEFC property that is being developed by Forest City
Washington. GSA and Forest City Washington signed a Development Agreement to transfer
parcels either by sale or ground lease over a period defined in the Development Agreement.
Acting as an agent for GSA, a separate entity, FC Remediation SEFC, Inc., conducted
remediation required on Parcel P. The remediation work is finished and the Completion Report
documents this work.

After public comment and after EPA issues a Final Remedy Decision for Parcel P, the
title for the portion of Parcel P that will become parkland will be transferred to the District of
Columbia. The title for the land under Building 173 and future Buildings P2 and P3 will be
transferred to Forest City Washington when the buildings are completed.

III. Summary of Environmental History

In 1999, GSA and EPA entered into an Administrative Order on Consent pursuant to
RCRA Section 3013, whereby GSA agreed to investigate the nature and extent of contamination
at the Facility, as well as perform certain Interim Measures to address contamination at the
Facility (the 1999 EPA Order). The investigations and cleanup activities are presented in the
RCRA Facility Investigation (RF1) Report for the Facility. An Interim Measures Work Plan for
Parcel P (IM Work Plan) was submitted to and approved by EPA in 2008. The IM Work Plan
described the proposed remediation of contaminated soil on Parcel P. The latest investigations
and cleanup were conducted in accordance with the EPA-approved IM Work Plan. Upon

-------
completion of the cleanup, GSA reported the activities and results to EPA in the Interim
Measures Completion Report for Parcel P dated April 16, 2010 (Completion Report).

A. Activities Completed Prior to 1999 EPA Order

GSA also conducted several Facility investigations and performed actions to address
contamination prior to the 1999 EPA Order. Sampling on Parcel P identified soils containing
concentrations of volatile organic compounds (VOCs), semi-volatile organic compounds
(SVOCs), metals, and polychlorinated biphenyls (PCBs) greater than EPA Region 3 residential
Risk-Based Concentrations (RBCs) or Action Levels (ALs) developed as part of the Description
of Current Conditions and Interim Measures/Site Stabilization Report, April 2001
(DCCIM/SSR). RBCs and ALs are constituent-specific values used by environmental
professionals to determine whether contaminant concentrations detected in environmental media
warrant further evaluation. The RBCs and ALs are both conservative screening values but may
be slightly different due to the input assumptions when developed. Affected soil was removed
from several areas on Parcel P, as described in the following paragraphs and shown in
Attachment 2.

In Area M-l, located northwest of the former Building 159E and southwest of Building
159, trichloroethylene (TCE), a VOC, was detected above residential Action Levels (ALs). In
1998, a 40-foot-square area was excavated from 0 to 8 feet below ground surface (bgs), and the
soil was disposed of off-site. Confirmation samples were taken from the sidewalls and bottom of
the excavation. All TCE concentrations were the EPA Region 3 residential RBC of 1,600
micrograms/kilogram (fig/kg).

In Area N-3, located directly west of Building 173, benzo(a)pyrene, a SVOC, was
detected in soil above residential ALs. In 1998, a 20-foot by 40 foot rectangle was excavated
from 0 to 4 feet bgs, and the soil was disposed of off-site. Confirmation samples collected from
the four sidewalls and bottom found all benzo(a)pyrene concentrations below the 9,000 (J-g/kg
residential AL except for the west side wall sample (2CN3 at 14,000 [ig/kg). Additional
excavation was conducted along the west and north sidewalls to the depth of the water table.
Three additional confirmation samples were collected from the north and west sidewalls and the
base of the excavation. These confirmation samples contained benzo(a)pyrene concentrations
below the 9,000 [ig/kg residential AL used for the excavation, but the concentrations exceeded
EPA Region 3 residential RBCs for either benzo(a)anthracene or benzo(a)pyrene. These data
were carried forward and included in the human health risk assessment for Parcel P.

Lead was detected above EPA's residential AL of400 milligrams/kilogram (mg/kg) in
Area N-4, located east of building 173. In 1999, a semicircular area with a radius of 20 feet was
excavated from 0 to 6 feet bgs and the soil was disposed of off-site. Confirmation samples were
collected from the sidewalls and base of the excavation and all results were below the residential
AL.

Area SF-1 originally represented an area located at the eastern end of the Site near the
original seawall. In this area, lead, copper and bis (2-chloroisopropyl) were detected above
residential ALs. The fill material placed in this area during the original seawall construction was
the likely source of contamination. In 1999, a 250 feet by 75 feet area was excavated from 0-10

-------
feet bgs and disposed of off-site. According to the DCCIM/SS report, three confirmation
samples were taken from the excavated soil. Results for bis (2-chloroisopropyl) ether were all
non-detect and results for copper were below the residential AL. Two of the samples, exceeded
EPA's action level for lead of 400 mg/kg. The specific sample locations were not recorded in
the DCCIM/SS. Subsequently, the entire original seawall was replaced by a new concrete
seawall. This activity resulted in an excavation covering 750 feet by 100 feet by 10 feet. This
excavation removed the wooden decking material and overlying fill. Six additional confinnatoiy
soil samples were collected from the base of this seawall excavation in January and February
1999, prior to backfilling. Two of the samples were analyzed for metals. Results indicated that
copper concentrations did not exceed the residential AL of 5,475 mg/kg in the DCIMM/SS, and
the lead concentrations in the samples were less than EPA's lead AL of 400 mg/kg.

In Area SF2-1, mercury was detected above the AL of 3 mg/kg, and a 20 feet by 30 feet
rectangular area was excavated from 0 to 4 feet bgs. Soil from the excavation was disposed off-
site. According to the DCCIM/SS report, confirmation samples were taken from the west, north,
east, and bottom of the excavation. Nickel concentrations ranged from 4 to 12 mg/kg, which is
below the residential AL and the residential RBC. Confirmation samples also contained bis (2-
chloroisopropyl) ether and copper at concentrations below the residential RBCs. Two
exceedances were noted: 650 mg/kg of lead in the base of the excavation, and 21 mg/kg of
mercury in the west side wall. The excavation was extended to the west and deepened, and two
additional confirmation samples were collected. The lead concentrations in these samples were
less than 400 mg/kg, and the sample from the base of the excavation contained 6 mg/kg of
mercury. These data were not carried forward into the risk assessment because the sample was
collected at a depth greater than 5 feet. Given the planned use for Parcel P, is it unlikely that
human exposure would occur at this depth, and this potential risk will be addressed through
institutional controls.

Nickel was detected in Area SF2-2 in concentrations that exceeded the residential AL of
100 mg/kg. In 1999, Area SF2-2 was excavated from 0 to 14 feet bgs, and the soil was disposed
of off-site. Three confirmation samples were collected from the sidewalls of the excavation and
all results were below the residential AL.

Nickel was also detected in Area SF2-3 in concentrations that exceeded the residential
AL. In 1999, Area SF2-3 was excavated from 0 to 4 feet bgs and disposed of off-site. Two
confirmation samples were collected from the sidewalls of the excavation and all results were
below the residential AL.

In 1995, GSA conducted a comprehensive environmental survey of former Building
159E, and identified the presence of PCB contaminated concrete in the floor of the interior and
exterior transfoimer rooms attached to the southwest comer of the building. According to the
DCCIM/SS report, in 1998, soil containing PCB concentrations greater than 1 part per million
(ppm) was removed from below the first floor transformer room. In addition, the Building 159E
Abatement Close-out Monitoring Report (2001) states that 4 to 6 inches of PCB-contaminated
concrete was removed from the floor of the transformer room. Subsequent soil samples collected
in this area did not contain detectable concentrations of PCBs.

-------
B. Activities Completed Under EPA Order

The purpose of the RCRA Facility Investigations (RFIs) was to fully determine the nature
and extent of any releases of hazardous waste and/or hazardous constituents at or from the
Facility. Parcel P was investigated in greater detail to prepare the parcel for redevelopment.
Areas of interest identified for Parcel P were fully delineated in previous studies and additional
areas of interest were identified and delineated.

Groundwater samples were collected in March 2002 and July 2002 from nine newly
installed wells on Parcel P (Attachment 3). Results were compared to the EPA Region 3 RBC
levels for tap water and maximum contaminant levels (MCLs), where available. MCLs are
maximum concentration levels established by EPA pursuant to the Safe Drinking Water Act, 42
U.S.C. §§ 300f, et seq. and codified at 40 C.F.R. Part 141. MN-SBMW09, which is located near
former Building 187, contained elevated levels of methyl-tert-butyl ether (MTBE; 7,530 jxg/1)
and thallium (7 jxg/1) in the March 2002 samples. EPA's Region 3 RBC for MTBE is 12 jig/l and
the MCL for thallium is 2 jig/1. Elevated levels of MTBE (4,700 jxg/1) were also detected in the
July 2002 samples. No other samples contained hazardous constituents at concentrations greater
than EPA Region 3 RBCs or MCLs. No further investigation of thallium was undertaken due to
the low concentration and isolated occurrence.

To evaluate the horizontal and vertical extent of MTBE in groundwater near MN-
SBMW09, two supplemental investigations were conducted by GSA in accordance with
workplans approved by EPA pursuant to the 1999 EPA Order. The investigations found that
MTBE concentrations in samples from MN-SBMW09 decreased consistently between 2002 and
2008. The investigations found that the horizontal extent of MTBE in groundwater was limited
to the area around MN-SBMW09, and that the vertical extent was also limited to the imconfmed
aquifer. MTBE was the only VOC detected in the groundwater samples. The November 2008
MTBE Supplemental Investigation Report concluded that no further action was required for
MTBE in groundwater in the vicinity of well MN-SB/MW09. EPA approved the report on
December 18, 2008, stating that the concentrations of MTBE detected in the recent sampling
were below the EPA Region 3 RBC for tap water of 12 ug/1. EPA stated that no further
monitoring was required and the wells could be abandoned The monitoring wells were
abandoned in January 2009 in accordance with the EPA-approved IM Work Plan.

Soil samples were also collected from the monitoring wells as they were installed. Soil
samples collected from borings MNSBMW05, N3-SBMW02, N3-SBMW03, and SF-SBMW01
at depths of 7 feet and 12 feet bgs contained concentrations of one or more of the following
compounds at concentrations greater than RBCs: benzo(a)anthracene, benzo(a)pyrene,
benzo(k)fluoranthene, indeno(l,2,3-cd) pyrene, and copper. These data were not carried forward
into the risk assessment because they were collected from a depth greater than five feet bgs.

Given the planned use for Parcel P, is it unlikely that human exposure would occur at this depth,
and this potential risk will be addressed through the implementation of institutional controls.

C. Interim Measures

Interim Measures (IM) are actions taken to control or abate ongoing risks to human health
and the environment in advance of the final remedy selection. This section describes the

-------
implementation of activities conducted pursuant to the Parcel P IM Work Plan. Previous
sampling conducted on Parcel P identified the following materials to be remediated:

¦ soil containing PCBs

¦ soil containing total petroleum hydrocarbons (TPH)

The interim measures conducted on Parcel P included the following; excavation, transport
and off-site disposal of contaminated soil; management of petroleum-contaminated soils
encountered during grading and excavation work for park improvements, utilities, paving, and
landscaping. Contaminated soil identified during previous investigations was excavated and
transported off-site for disposal. Verification samples demonstrated that remaining soil met
standards protective of the future recreational use of the property.

Former Building 158 Process Pit: Soil in and around the former Building 158 process pit
was excavated and removed for off-site disposal. Soil within 2 feet of the pit (vertically and
horizontally) was removed for off-site disposal as petroleum-contaminated soil. The limits of
excavation were extended 10 feet to the east and west of the pit due to visibly stained soil and
elevated photoionization detector/flame ionization detector readings at the southeast and
southwest limits of the excavation. Confirmation soil samples were analyzed for PCBs and
TPH-DRO. PCBs were not detected in the soil samples, and the TPH concentrations were not
above the District of Columbia Tier 0 criterion of 100 mg/kg for TPH. Therefore no additional
excavation was conducted and the excavation was backfilled to final grade.

Foimer Building 187 Process Pit: Soil in and around the former Building 187 process pit
was excavated and removed for off-site disposal. Soil within 2 feet of the sump (vertically and
horizontally) was removed for off-site disposal as petroleum-contaminated soil. Confirmation
soil samples collected from the floor and side walls of the excavation were analyzed for TPH-
DRO and VOCs (including MTBE). The TPH concentrations were less than the District of
Columbia Tier 0 criterion of 100 mg/kg. MTBE was not detected in any of the verification soil
samples. Therefore no additional excavation was conducted, and the excavation was backfilled
to final grade.

Former Building 187 Transformer Room: PCB contaminated soil beneath the former
Building 187 transformer room was excavated and removed for off-site disposal. Soil was
removed to a depth of five feet bgs, based on the soil analytical results from three borings
collected from beneath the former transformer room. The excavation area extended 5 feet
beyond the perimeter of the former transformer room and covered approximately 1,100 square
feet. In accordance with the IM Work Plan, GSA classified the soil as Class 5 (PCB-
contaminated) and shipped the soil off-site for disposal. Confirmation soil samples were
analyzed for PCBs. One soil sample contained 0.3 mg/kg Aroclor 1260, which is above the
current EPA Region 3 residential RBC of 0.22 mg/kg. After additional excavation, the second
confirmation sample contained PCB concentrations below the EPA Region 3 residential RBC,
and no additional excavation was conducted. The excavation was backfilled to final grade.

Canal Basin Excavation: The new waterfront park has a water feature called the Canal
Basin on the west side of Building 173. Construction of the Canal Basin required excavation of

-------
existing soil. An environmental technician was present during initial excavation of the Canal
Basin to identify potentially contaminated soil. Soil samples were collected and analyzed for
PCBs and TPH-DRO. Based on the soil sampling results and as established in the IM Work
Plan, GSA classified portions of the soil in the Canal Basin excavation as Class 3 soil (petroleum
contaminated). The petroleum-contaminated soil from the Canal Basin excavation was
transported for off-site disposal. PCBs were not detected in any of the soil samples from the
Canal Basin excavation, which confirms that there is no evidence of a PCB release in this area.
The TPH-DRO concentrations in all the samples from the canal area (maximum 42 mg/kg) were
less than the District of Columbia Tier 0 criterion of 100 mg/kg.

IV. Evaluation of EPA's Proposed Remedy

This section provides a description of the criteria EPA uses to evaluate proposed
remedies under the Corrective Action Program. The criteria are applied in two phases. In the
first phase, EPA evaluates three criteria, known as threshold criteria. In the second phase, EPA
uses seven balancing criteria to select among alternative solutions, if more than one is proposed.
Because current conditions at Parcel P meet the threshold criteria and because EPA is not
selecting among alternatives, a complete evaluation of the balancing criteria is not necessary.

The following is a summary of EPA's evaluation of the threshold criteria:

1. Protects Human Health and the Environment - This proposed remedy protects
human health and the environment from exposure to contamination given the planned
commercial and recreational use at Parcel P. Soil excavations within Parcel P shall require the
owner to follow the soil use restrictions, as described in Section V, to ensure protection of human
health in the future. If groundwater from Parcel P is used as a potable water supply, the
estimated future potential health risks exceed EPA guidelines. However, the DC Water and
Sewer Authority supplies and will continue to supply potable water to Parcel P and the rest of the
Facility, which will eliminate this potential source of risk. To further preclude potential
exposure, institutional controls will be implemented to limit possible future uses of soil and
groundwater at Parcel P.

2. Achieves Media Cleanup Objectives - EPA's proposed remedy meets the
appropriate cleanup objectives based on assumptions regarding current and reasonably
anticipated land and groundwater uses, as described in Section V. Therefore, no additional
action is required for the planned recreational and commercial use at Parcel P, except for
recording the groundwater and land use restrictions, as discussed above, and to comply with
those restrictions.

3. Remediates the Source(s) of Releases - In all remedy decisions, EPA seeks to
eliminate or reduce further releases of hazardous wastes or hazardous constituents that may pose
a threat to human health and the environment. GSA, as part of its work at the SEFC, has
remediated the sources of releases as described in the Section III, Summary of Environmental
History.

-------
V. Institutional Controls

Under this proposed remedy, some concentrations of contaminants may remain in the
groundwater and soil at Parcel P above levels appropriate for residential and domestic uses. In
response, the proposed remedy will require the owner of Parcel P to implement institutional
controls (ICs) to restrict use of Parcel P property and groundwater to ensure that any remaining
contamination does not pose a threat to human health or the environment. ICs are generally non-
engineered instruments such as administrative and/or legal controls that minimize the potential
for human exposure to contamination by limiting land or resource use. ICs also help to protect
the integrity of the remedy.

ICs to be implemented under the remedy consist of a restrictive covenant to be recorded
with the property deed when ownership is transferred from GSA to the District of Columbia, as
well as an environmental covenant, to be filed pursuant to the District of Columbia Uniform
Environmental Covenants Act of 2006, D.C. Code § 8-671. These ICs will minimize the
potential for human exposure to contamination by limiting possible future uses of soil and
groundwater at Parcel P. The restrictions to be included in the restrictive covenant and the
environmental covenant are:

1. The use of the Parcel P shall be limited to recreational and commercial activity. In no
event shall Parcel P or any part thereof be used for any of the following purposes:

a) Single family or multi-family dwellings and other residential-style facilities, or
otherwise as a residence or dwelling quarters for any person or persons.

b) Use as a daycare center.

c) The planting of crops for human consumption.

2. Any digging, excavating, grading, or other soil moving activities shall be conducted on
Parcel P or any part thereof including in compliance with all applicable federal, state and
local rules, regulations and ordinances. Soil removed from a depth of two feet and below
cannot be reused on-site. Soils removed from a depth of two feet and below shall be
disposed of off-site in accordance with state, federal and local regulations and replaced
with clean fill.

3. Groundwater underlying Parcel P shall not be used for any purpose (including, without
limitation, human consumption, commercial or agricultural purposes) and no wells for the
extraction thereof shall be installed, permitted or utilized on the Parcel P or any part
hereof. However, monitoring wells may be installed and operated on Parcel P solely for
the purpose of environmental sampling, monitoring and testing of groundwater.

These ICs are enforceable through Section 110 of the District of Columbia Uniform
Environmental Covenants Act of 2006, D.C. Code § 8-671.10. If the owner of Parcel P fails to
meet its obligations under the environmental covenant or EPA, in its sole discretion, deems that
additional ICs are necessary to protect human health or the environment, EPA will consider the

-------
use of enforcement authorities to require and enforce additional ICs.
VI. Environmental Indicators

Under the Government Performance and Results Act (GPRA), EPA has set national goals
to address RCRA corrective action facilities. Under GPRA, EPA evaluates two key
environmental clean-up indicators for each facility: (1) Current Human Exposures Under Control
and (2) Migration of Contaminated Groundwater Under Control. The SEFC, including Parcel P,
met these indicators on September 8,2003 and September 29,2004 respectively.

VII.	Financial Assurance

Due to the minimal cost associated with the proposed remedy, financial assurance is not
required for Parcel P.

VIII.	Public Participation

Interested persons are invited to comment on EPA's proposed remedy. The public
comment period will last thirty (30) calendar days from the date that notice is published in a local
newspaper. Comments may be submitted by mail, fax, e-mail, or phone to Ms. Deborah
Goldblum at the address listed below.

A public meeting will be held upon request. Requests for a public meeting should be
made to Ms. Deborah Goldblum at the address listed below. A meeting will not be scheduled
unless one is requested.
