Site Name and Location

Operable Unit No. 2
Area of Concern  (AOC) 63
Tobyhanna Army Depot
Tobyhanna, Monroe County, Pennsylvania

Statement of Basis and Purpose

     This decision document presents a determination that no further action is necessary to protect human
health and the environment for Operable Unit No. 2  (OU2), the former

polychlorinated biphenyl (PCB) transformer substation site at the Tobyhanna Army Depot, Tobyhanna, Monroe
County, Pennsylvania  (TYAD).   This determination was developed in accordance with the Comprehensive
Environmental Response,  Compensation, and Liability Act of 1980  (CERCLA),  as amended by the Superfund
Amendments and Reauthorization Act of 1986 (SARA), and the National Oil and Hazardous Substances Pollution
Contingency Plan  (NCP),  40 C.F.R. Part 300.  This document was prepared as a joint effort between the U.S.
Army, Pennsylvania Department of Environmental Protection (PADEP) and the Environmental Protection Agency
(EPA) .  The no further action decision is supported by documents contained in the Administrative Record.

     The Commonwealth of Pennsylvania concurs with this action.

Description of the Selected Remedy

     A no further action alternative is the selected remedy for OU2.   Additional sampling or monitoring will
not be necessary because any potential unacceptable risks to human health or the environment have been
addressed as part of the 1994 removal action.  At this time, there are no future plans for the
development of AOC #63.   The area is currently zoned for industrial use and, as long as TYAD occupies the
property, is expected to remain industrial.  Because of the negligible risk, there is also no need for
fencing or other controls to prevent access by TYAD employees to this area.

                    REMEDIAL ALTERNATIVE SELECTION
                       FOR OPERABLE UNIT #2
Declaration
     The no further action remedy selection is based upon the confirmation sampling results which were found
to be within the EPA's acceptable risk range.  Therefore the selected remedy is protective of human health
and the environment.  Because This remedy will not result in hazardous substances remaining on-site above
health-based levels, and the levels of hazardous substances remaining on-site will allow for unlimited use
and unrestricted exposure, a five-year review will not be necessary for OU2.

                      DECISION SUMMARY

1.0  INTRODUCTION

     On July 14, 1989, the Tobyhanna Army Depot  (TYAD) was proposed for inclusion to the Comprehensive
Environmental Response, Compensation, and Liability Act  (CERCLA) National Priorities List  (NPL) and
subsequently added to the final NPL on August 30, 1990.  The Department of the Army  (DA) has been
granted the authority to be the lead agency at TYAD under Executive Order 12580 and CERCLA, as amended by the
Superfund Amendments and Reauthorization Act of 1986  (SARA).  The United States Environmental Protection
Agency  (EPA) and the Commonwealth of Pennsylvania have authority at TYAD as support agencies.  The EPA Region
III and the DA negotiated a comprehensive Federal Facility Agreement  (FFA) , which was signed by EPA on
November 19, 1990, and became effective on January 19, 1991.  The primary purpose of the FFA is to ensure
that environmental impacts associated with past disposal activities at TYAD are thoroughly investigated, and
appropriate CERCLA remedial action alternatives are developed and implemented to protect human health and the
environment.  The FFA has identified sixty-five  (65)  Areas of Concern  (AOCs) within TYAD.

     A CERCLA remedial action is often divided into operable units  (OUs).  As defined in the National Oil and
Hazardous Substances Pollution Contingency Plan  (NCP), an "operable unit means a discrete action that
comprises an incremental step toward comprehensively  addressing site problems.  This discrete portion
of a remedial response manages migration, or eliminates or mitigates a release, threat of a release, or
pathway of exposure. The cleanup of a site can be divided into a number of operable units, depending on the
complexity of the problems associated with the site.   Operable units may address geographical portions
of a site, specific site problems, or initial phases  of an action, or may consist of any set of actions
performed over time or any actions that are concurrent but located in different parts of a site."  This
Record of Decision  (ROD) presents a determination that no further action is necessary to protect human health
and the environment at Operable Unit No. 2 (OU2), which consists of AOC #63, the former PCB transformer
substation site, located at Tobyhanna Army Depot, Tobyhanna, Pennsylvania. The no further action decision is
the final action for OU2. Other OUs have been and will be defined by separate
investigations.

     The no further action decision is based on the results and findings of the 1996 Verification Study (VS)
report, data collected as part of the 1994 time-critical removal action, and conclusions presented in the
risk evaluation.

     Based on the results of the risk evaluation, it was determined that OU2 poses no current or future
potential, unacceptable human health risks.  Additionally, any contaminants which may have migrated into the
storm drainage system from OU2 will be addressed under the ongoing basewide ecological risk assessment.
Therefore, the conditions at OU2 do not require further action to be protective of human health and the
environment.

     A feasibility study (FS), which normally develops and examines remedial action alternatives for a site,
was not performed for OU2 since the results of the risk evaluation indicate that no further remedial action
is required at AOC #63.

2.0   SITE NAME, LOCATION,  AND DESCRIPTION

     TYAD is located in Monroe County, Pennsylvania,   approximately 15 miles southeast of Scranton,
Pennsylvania, adjacent to the Village of Tobyhanna (Figure 1).  Although the name and mission have changed
since its inception in 1909, TYAD has always been a Government-owned and Government-operated facility.  TYAD
was used for field artillery training and ordnance storage during World War I.  After several years of
inactivity, TYAD was used as a training, equipment storage, and detention center during World War II.  TYAD
was again deactivated until construction of the current installation in the early
1950s.

     TYAD now encompasses approximately 1,293 acres  (2.2 square miles).  As a communications-electronics
maintenance and supply depot, the current function of TYAD is the design, fabrication, repair, and
modification of a wide range of communications and electronics systems.  These systems, which range in size
from handheld radios to satellite communications ground terminals, are associated with navigation, aircraft
survivability, surveillance, and electronics warfare.

Description of AOC #63

     AOC #63 is a former electrical substation located at the corner of Squire and First Streets and

-------
encompasses an area measuring 67 feet by 78 feet  (Figure 2).   AOC #63 is partially fenced and is bounded by
the coal pile/heating plant to the south; additionally, several inches of coal cover much of the
western and southwestern portions of this AOC.  The former substation at AOC #63 served both the industrial
and residential areas of TYAD from the early 1950s until 1980.  AOC #63 included two transformers designated
as "North Side" and "West Side".  On April 15, 1980, the switch gear was struck by lightning and destroyed.
As a result of the lightning strike and the age of the eguipment, the substation was replaced by the
substation located at the corner of Hap Arnold Boulevard and Sguire Street.

     Samples of oil from the two transformers, which from all records appear to have been in place since the
substation began operation, were submitted for PCB analysis on March 11, 1991. Analytical results were
reported as less than 0.05 milligrams per kilogram  (mg/kg)  and 6.4 mg/kg for the "North Side" and "West
Side" transformers, respectively.  Pursuant to 40 C.F.R.  Part 761.3, both transformers would be classified
as "non-PCB transformers" under the Toxic Substances Control Act  (TSCA) .  Oil was drained from both
transformers on January 29, 1993 and subseguently disposed in accordance with the requirements of 40
C.F.R.  Part 761, Subpart D.  The transformer "carcasses" were transferred by the Defense Reutilization and
Marketing Office (DRMO)  to Booth & Sons Scrap Yard, Inc., Moosic, PA and were transported offsite on May 20,
1993.

      
      
-------
     The U.S. Army and EPA,  in consultation with PADEP,  published the Administrative Record for the
time-critical removal at AOC #63 on January 14,  1995 (TYAD & EPA, 1995).   The Administrative Record
supporting the time-critical removal action was available for public review and comment until February 12,
1995.  No comments were received during the public comment period.

     On May 16,  1996, TYAD sampled the areas where the highest concentrations of PCBs were located for
chlorinated benzenes.  In some transformers, chlorinated benzenes are used in addition to PCBs to make the
oil in the transformers more fluid.  Since no previous samples had been analyzed for chlorinated benzenes,  at
the recommendation of EPA, TYAD took four additional samples at AOC #63.   The samples were taken at a depth
of two feet,  which was below the area that was excavated and filled with clean soil, to ensure that these
compounds were not present at levels of concern.  Analytical results are provided in Attachment 4 and did not
indicate the presence any chlorinated benzenes above the laboratory detection limit.

     Concentrations of residual PCBs on-site in both excavated and non-excavated areas range from below
detection limits to a high of 9.89 mg/kg.   (See Table 1).   The elevated value of 9.89 is in an area which was
excavated, but confirmation samples taken in that area could not be adeguately documented.  The remainder of
the results are all below 5 mg/kg.

     The notice of availability of the PRAP document was published in The Pocono Record on August 20, 1996.
A public comment period was held from August 20, 1996 through September 20, 1996.  In addition, a public
meeting was held on September 18, 1996, to present the PRAP for OU2 and to answer guestions and
receive public comments.  The public meeting minutes have been transcribed and a copy of the transcript is
available to the public at the aforementioned locations.  A Responsiveness Summary, included as part of this
ROD, has been prepared to respond to the significant comments, criticisms, and any new relevant information
received during the comment period.  Upon signing the ROD, the Army will publish a notice of availability of
this ROD in The Pocono Record, and place the ROD in the Administrative Record located in the repositories
mentioned above.

5.0 SCOPE AND ROLE OF THE OPERABLE UNIT RESPONSE ACTION

     To conduct investigation and cleanup activities more effectively, it is customary to manage each
discrete portion of an NPL site as an operable unit  (OU).  For TYAD, OU1 corresponds to AOC #4 and AOC #7,
which are collectively termed as Areas A and B.  OU1 addresses the area of groundwater contamination which
has migrated off-base.  This ROD addresses TYAD AOC #63 as OU2.  TYAD OU3 corresponds to AOC #37 and AOC #38,
which are also referred to as Building 10-C and Building S-90, respectively. The ROD for OU3 was finalized on
July 12, 1996.  One or more additional OUs may be defined in the future for TYAD based on an
evaluation of existing data.

    EPA has reviewed the March 1996 USACHPPM risk evaluation for OU2 and has concurred with the Army's
conclusion that the residual contamination found at the PCB transformer substation site does not pose
unacceptable risks to workers or any potential future residents.  Therefore, OU#2 is deemed to be already
protective of human health and the environment.

6.0 SITE CHARACTERISTICS

6.1 SITE TOPOGRAPHY

     TYAD lies in the southern New York section (locally termed the Pocono section) of the Appalachian
Plateau Physiographic Province.  The section is characterized by mature glaciated plateaus of moderate relief
with broad intervening lowlands. Within TYAD, the relief varies over a range of approximately 220
feet  (ft); the lowest elevation  (1,930 ft) occurs south of Barney's Lake; whereas, the highest elevation
(2,150 ft) occurs on Powder Smoke Ridge.

6.2 ADJACENT LAND USE

     TYAD is bordered to the north, east, and west, by the Tobyhanna State Park Reserve (Figure 1).  The area
south of TYAD is owned by various residential property owners within the Village of Tobyhanna.

6.3 SURFACE WATER HYDROLOGY

     Figure 3 shows the surface drainage features at TYAD.  No through-flowing drainage ways exist on TYAD.
Surface drainage, originating within TYAD, flows principally into Cross Keys Run, Barney's Lake, and Hummler

-------
Run.  Oakes Swamp receives drainage from the western and northern portions of TYAD and discharges to the
north-northwest.

     At OU2, a stormwater drain opening is located in the north corner of the former substation.  A small
drainage trough leads from OU2 to the drain opening.  This stormwater drain flows into Barney's Lake.

6.4 GEOLOGY/HYDROGEOLOGY

     The surficial deposits at OU2 consist of fill derived from glacial and alluvial deposits.  The
relatively flat topography was influenced by the construction of the industrial area of the Depot in the
early 1950s.  The depth of the fill is approximately 80 feet based on the contour mapping  (USAEC-WES, 1996)
inferred from the monitoring well construction logs at OU1, and the inactive sanitary landfill  (AOC #1).   The
surface water from OU2 is collected by the storm drain system which drains through 48-inch pipe outlets to
the Hummler Run Watershed.

     The bedrock at OU2 belongs to the Poplar Gap Member of the Devonian Age Catskill Formation.  The Poplar
Gap Member consists of fine to medium grained sandstones.  The contour elevations inferred by existing
monitoring well data indicates that the top of bedrock would be at the 1930-foot elevation.  The structural
geology in the OU2 area is limited.  The existing information (SEVON, 1975)  indicates a low amplitude
syncline axis located approximately 750 feet south of the OU2 area.  The relatively low amplitude and limited
information on structural features would not define groundwater flow as controlled by structure.  The
anticipated groundwater flow pattern in the upper bedrock would have a general south to south-east flow
pattern.

6.5 ECOLOGY

     With respect to ecology, OU2 has no wetlands, protected or endangered species, nor any other sensitive
environments identified nearby.  Any drainage from OU2 would have flowed into the nearby stormwater drain
which eventually discharges into Barney's Lake.  A basewide ecological risk assessment is underway at TYAD
which will determine whether storm water drainage has had a significant impact on Barney's Lake.


     

7.0 SUMMARY OF SITE RISKS

7.1    Exposure Assessment

     As part of the decision-making process for AOC #63, the U.S. Army Center for Health Promotion and
Preventive Medicine (USACHPPM) completed a risk evaluation to determine the risks to humans posed by any PCB
contamination remaining after the contaminated soil was removed  (USACHPPM, 1996).  The current and
future use for this area is expected to remain industrial, and therefore the risk would be greatest to
workers who may be exposed.  However, USACHPPM also evaluated risk to future on-site residents even though
residential use of the property in the future is not anticipated.

     There are three potential routes of contaminant uptake for the considered populations - inhalation,
ingestion, and dermal uptake.  Of these routes, inhalation is not seen as having an opportunity to occur.
PCBs do not readily volatilize from soil, due to binding tightly to the soil matrix.  The presence of
vegetation in the area mitigates any fugitive dust, which prevents inhalation of PCB-containing dust.  This
pathway was therefore not included in the exposure assessment and the risk evaluation.  Dermal contact with
PCBs is not viewed as presenting a likely threat given its relatively low dermal uptake factor  (an assumed
value by EPA Region III of approximately 6%).   However, in its review of the risk evaluation, EPA did
consider whether the dermal pathway would be expected to increase cancer risks beyond the NCP target risk
range.  EPA does not expect that to be the case; risks are expected to remain within 1 X 10-4 and IX 10-6.
Ingestion of PCBs from ground water is unlikely at this site due to the low remaining concentration in the
soil and the low potential for PCB migration to ground water.  The ground-water ingestion pathway has been
eliminated as a result of this information.  Only incidental soil ingestion is considered in the screening of
the materials provided, because the pathway still exists for current and future site workers, and future
onsite residents.  (USACHPPM, 1996)

7.2    Toxicity Assessment

     PCBs may be absorbed by all exposure routes.  The liver, skin, and both the immune and endocrine

-------
 (hormones) systems are all considered target organs with chronic exposure to PCBs.   Skin irritations, such as
acne-like and rash-like symptoms, can occur in people exposed to PCBs.  Liver, kidney, and skin damage Occurs
in rabbits after their skin has been repeatedly exposed, and single large dose exposures on the skin caused
death in rabbits and mice.  Studies in the workplace suggest that exposure to PCBs may also cause irritation
of the nose and lungs.  Rats and other animals which breathed PCBs over several months developed liver and
kidney damage, but the levels necessary to produce these effects were high.

     Worker studies do not provide enough information to determine if PCBs cause cancer in humans.  Rats that
ate fixed amounts of PCBs throughout their lives developed cancer in their lifetimes.  Based on the cancer
data in animals, the USEPA has determined that PCBs are probable human carcinogens.  (USACHPPM,1996)

7.3    Risk Evaluation

     Due to the site's small size and PCBs being the lone contaminant of concern (COG), the risk evaluation
for AOC #63 was conducted using a variation on the traditional methodology used in a baseline risk
assessment.  In this characterization, the USEPA Region III Risk-Based Concentration  (RBC) Table  (USEPA,
July-December 1995) was used to screen the soil PCB levels for human receptors.  The table was used to screen
for potential cancer risk (the more conservative endpoint) in both a present and future commercial/industrial
and future residential scenario. Specifically, the table's reported concentrations in soil that correspond to
a 1 x 10-6 (i.e., one in one million) incremental cancer risk (ICR) due to site exposure were used.

     In order to determine the ICR due to the residual contamination left onsite, a 95 percent Upper
Confidence Level (UCL) of the sampling mean was calculated for use as the average PCB concentration.  The 95
percent UCL is defined as a value that, when calculated repeatedly for randomly drawn subsets of site data,
eguals or exceeds the true mean 95 percent of the time.  As a result, the 95 percent UCL is a conservative
estimate of the average PCB concentrations remaining at this site.  The 95 percent UCL for this site was
calculated to be 2.15 mg/kg (Table 1).  This number is divided by the RBC value for the
commercial/industrial and residential user, and then multiplied by 1 x 10-6  (one millionth) to present the
potential carcinogenic risk posed by exposure to this concentration of PCBs, which is based on the 1 x 10-6
cancer risk used in the RBC tables.  For AOC #63, the carcinogenic risk for industrial exposure is 2.9 x 10-6
and for residential exposure the risk is 2.6 x 10-5 (Table 2). These values are within EPA's acceptable
target risk range of 1 x 10-4 to 1 x 10-6.  (USACHPPM, 1996)

Data Validation

     With the exception of sampling point 78,  all sampling data used in the calculation of the 95 percent UCL
were validated according to the Tobyhanna Army Depot,  Monitor/Residential Well Sampling Program and
Verification Studies - Quality Assurance Project Plan, ELIN A009.  Wayne Analytical & Environmental
Services, Inc. performed the analysis for sampling point 78.  A duplicate and spike were performed on every
tenth soil sample analyzed by Wayne.  The duplicate result for sampling point 78 was 2.39 mg/kg of PCB versus
the original result of 4.19 mg/kg. The higher result was used in the calculation of the 95 percent UCL.  The
soil sample for location 78 was analyzed using EPA Method 8080 in accordance with EPA's Test Methods for
Evaluating Solid Waste Manuals  (SW-846).   (USACHPPM, 1996)

     The 95 percent UCL on the sampling mean calculation results are presented below and were
developed using the USEPA Supplemental Guidance to RAGS:  Calculating the Concentration Term.
non-detect samples were accounted for by using half the detection limit in the 95 percent UCL
calculation.  The 95 percent UCL on the sampling mean is the most representative of the
concentration that would be contacted at the site.

7.4    Conclusion

     Current and future site workers and future on-site residents were considered to be the populations most
at risk.  It was assumed that each of these populations could potentially contact PCB-contaminated soils
through incidental soil ingestion.  Based on the EPA Region III commercial/industrial soil RBC, a cancer risk
of 2.9 x 10-6 was estimated for current and future site workers.  Based on the residential soil RBC, a risk
value of 2.6 x 10-5 was calculated for potential exposure to PCBs by future residents (both adults and
children).

     For Superfund sites, EPA generally considers cancer risks from 1 X 10-6 to 1 X 10-4 to be acceptable.
Because the Tobyhanna OU2 risks are within this range, EPA has concurred with the Army's conclusion that the
residual contamination found at AOC #63 does not pose unacceptable risks to workers or potential
future residents.  Furthermore, significant ecological effects are not expected to occur because of the small
size of AOC #63, its distance from critical habitats, and the relative immobility of PCBs.  Prior to the
removal, surface drainage from this area which may have contained PCBs would have flowed into the nearby
stormwater drain.  This drain eventually discharges into Barney's Lake.  The Army is currently conducting a
basewide ecological risk assessment at TYAD to determine whether storm water drainage has had any ecological
impact on the lake.

     In summary, further response actions at AOC #63 are deemed unnecessary to protect human health and the
environment.  In addition, the residual PCB levels are within cleanup standards established by Pennsylvania's
Land Recycling Act of 1995, Act 2.

8.0    DESCRIPTION OF THE "NO FURTHER ACTION" ALTERNATIVE

     The preferred alternative for AOC #63 id the No Further Action Alternative.  Additional sampling of
monitoring will not be necessary because any environment have been addressed as part of the removal action.
At the time of this ROD, there are no future plans for development of AOC #63.  The area is currently zoned
for industrial use, and as long as TYAD occupies the property, is expected to remain industrial.  Because of
the negligible risk, there is also no need for fencing or other controls to prevent access be TYAD employees
to this area.  It is highly unlikely that this site would be used as a residential area; however, if this
were to occur in the future, the risk evaluation shows that residual PCB levels are also within acceptable
risk ranges for residential scenarios.  Project Managers from the Army, EPA and PADEP collectively developed
this ROD and concur with this decision.  This alternative will have no associated costs.


9.0    RESPONSIVENESS SUMMARY

     The purpose of the Responsiveness Summary is to provide the public with a summary of citizen comments,
concerns,  and guestions about OU2.

     No written comments were received during the 30 day public comment period.  In addition, no verbal
comments were presented during the September 18, 1996 public meeting regarding OU2.
