1 Introduction
The General Electric (GE)/Shepherd Fann Site is located in East Flat Rock, North
Carolina. General site features are depicted on Figure 1-1. The site consists of two non-
contiguous areas referred to as the GE Subsite and Shepherd Farm Subsite. The GE Subsite
(Figure 1-2) is approximately 120 acres in size and includes the GE manufacturing and
distribution facilities. The Shepherd Fann Subsite (Figure 1-3) is approximately 50 acres in size
and is comprised of residential and agricultural land.
The Remedial Design/Remedial Action (RD/RA) for the site addresses soil and
groundwater at both subsites. The designs for soil and groundwater are proceeding in different
stages and different schedules. This report addresses only the soil portion of the RD/RA for the
GE Subsite.
The preliminary (30%) design for remediation of PCB-contaminated soil at Landfill A,
Landfill 13, and the Dry Sludge Impoundment (OSI) was completed in February 1998 (HSI
Geo Trans, 1998a). Additional data collection activities were completed in May 1998 in
accordance with the Intennediate Design Investigation Work Plan dated April 1998 (HSI
GeoTrans, 19986).
The two purposes of this interim report are to (!) describe results of the soil data collected
since the 30% design in accordance of the Intennediate Design Investigation Work Plan and (2)
describe recommended modifications to the ROD remedy based on these new results. A pre-
final (90%) remedial design report and RA work plan for soil remediation at the GE Subsite will
be completed after agency review and approval of these recommended modifications.
Section 2 of this report summarizes the soil remediation goals and remedy described in
the ROD. The results of the soil investigations completed during the lntennediate Design
Investigation are described in Section 3. Laboratory reports (Fonn l's) and Chain of Custodies
for the data presented in Section 3 are provided in Appendix A. Proposed modifications to the
ROD remedy are discussed in Section 4. Section 5 is a list of references.

2 ROD Remedy
A remediation goal of 10 parts per million (ppm) total PCBs was established in the
Record of Decision (ROD) (U.S. EPA, 1995a) for soil remediation at the GE Subsite. This goal
is based on the Baseline Risk Assessment and applicable or relevant and appropriate
requirements (ARARs).
The remedy described in the ROD for Landfill A, Landfill Band the DSI consists of a
multi-layered cap in areas exceeding a total PCB concentration of 10 ppm. The multi-layered
cap includes a composite liner consisting of 18 inches of clay, a flexible membrane liner, and if
necessary, a drainage layer.

3 Intermediate Design Data
This section presents the results of the soil investigations performed after the 30% design,
in accordance of the Intermediate Design Investigation Work Plan (HSI GeoTrans, 1998b).
3.1 DSI
Nearly 210 soil samples have been collected historically in and around the OSI to
delineate the extent of PCBs in the soil. Additional surficial soil samples were collected at the
OSI on May 14, 1998 to confirm the western and northern boundaries of the impoundment. A
total of four soil samples were collected at a depth of O to 1 feet using a hand auger. The four
soil samples were analyzed for PCBs using EPA Method 8081. Figure 3-1 shows the location of
the surficial soil samples.
Total PCB concentrations for the four additional samples ranged from not detected to
0.22 ppm as shown on Figure 3-1. Laboratory reports (Form I's) are provided in Appendix A.
The extent of PCBs in and around the OSI has been determined.
All four surficial soil samples were split during collection. The split samples were
analyzed in the field using immunoassay kits. All four field-analyzed samples were reported as
not detected (less than l ppm) for PCBs. These field results are consistent with the laboratory
results.
3.2 Landfill A
3.2.1 Exploratory Trenching
Site investigations at Landfill A in 1997 included surface geophysics surveys (GPR and
EM), soil gas survey, surficial soil sampling, subsurface soil sampling, and groundwater
sampling (described in HSI GeoTrans, 1998a). The extent of Landfill A based on the PCB
concentrations in the surficial soil is depicted on Figure 3-2. The total area of surficial PCB
contamination is 0.9 acres. Based on the GPR data, the maximum depth of the debris in Landfill
A was determined to be eight feet. Landfill A was also visually inspected to a depth of 8 feet in
July 1997 when piping was installed for the accelerated groundwater remediation system
(AGRS). The location of the AGRS trench is depicted in Figure 3-2. Note that no debris was
identified in the subsurface in the AGRS trench.
Exploratory trenching was performed in May 1998 at Landfill A to ( 1) confirm the lateral
and vertical delineation of the landfill provided by existing data and (2) to visually examine the
characteristics of the buried debris.

Two trenches, 75 feet in length, were dug to a depth of 9 to IO feet using a backhoe. The
trenching was performed on June 8 and 9, 1998. The trenches were advanced both laterally and
vertically until native earth material was identified and visible debris was no longer present.
Excavated material was stored on a plastic liner near the trench and placed back into the trench at
the completion of the investigation. The top of the trench was brought to final grade using
approximately six inches of gravel.
Figure 3-2 shows the location of the two exploratory trenches. Cross-sections of the
northern and southern trench are depicted in Figures 3-3 and 3-4, respectively. Gray sand (fill)
was present from the base of the asphalt and gravel to a depth of approximately two feet. The fill
was underlain by reddish-orange silty clay (native saprolite). Buried debris was identified at
several locations to a maximum depth of nine feet. Buried debris included metal banding, wire,
glass, and crushed drums or drum remnants containing solid paint residue and other gray
material. No buried, intact metal drums or other containers of liquid waste were identified.
Ashes and charred debris were present in the debris indicating that the debris was periodically
burned before burial. A sharp contact was observed between the debris and the native reddish-
orange silty clay. A chemical odor was present in some of the debris and soil with PlD readings
ranging from Oto 7.1 ppm. Much of the surficial soil (upper foot) contained a black residue
which may be the results of historic application of oil for dust suppression.
The trenching information supports the data obtained from the surface geophysics. Areas
of suspected buried debris with the high concentration geophysical designation were areas that
consistently contained buried debris, including metal. Areas of suspected buried debris with a
low concentration geophysical designation were either (I) more deeply buried debris or (2) semi-
consolidated sand. The depth to bedrock at Landfill A is 30 to 35 feet. The semi-consolidated
sand is heavily weathered bedrock that has not weathered as completely as the surrounding
material. The backhoe was capable of penetrating the semi-consolidated sand material. The
maximum depth of nine feet observed from the trenching is close to the maximum depth of eight
feet determined from the GPR data.
3.2.2 Subsurface Soil Sampling
The maximum vertical extent of the buried debris in Landfill A is 9 feet based on the
exploratory trenching. Additional subsurface soil sampling was performed to estimate the
vertical extent of PCB-contaminated soil inside the landfill area but outside the area of the buried
debris.
Subsurface soil samples were collected on May 22, 1998 at two locations in Landfill A;
one location was in the northern portion of the landfill and the other location was in the southern
portion of the landfill. Samples were collected at depths of 1 to 2 feet and 2 to 3 feet at each
location using a hand auger. The samples were analyzed using EPA Method 8081.

Total PCBs in the subsurface soil samples ranged 0.64 to I 00 ppm. Figure 3-5 displays
the vertical extent of PCBs at the two sample locations. A total PCB concentration of 28 ppm
was detected at the two to three foot depth interval. These results indicate that the PCB-
contaminated soil may extend to a depth of at least three feet in areas outside the buried debris
trenches. Laboratory results are included in Appendix A.
3.3 Shepherd Farm
Subsurface soil samples were collected at the Shepherd Farm Subsite to determine the
vertical extent ofVOCs in the soil where portions of drums were uncovered during the soil
excavation in the fall of 1997. Samples were collected at three different depths with a hand
auger and analyzed for VOCs using EPA CLP methods. Soil samples were also screened in the
field using a PID. Due to shallow refusal using the hand auger, three different boring were used
to obtain soil samples from the three depth intervals. The locations of the borings are shown on
Figure 3-6.
Table 3-1 summarizes the results of the soil sampling. PCE was the only VOC detected.
Concentrations of PCE ranged from not detected to 0.13 ppm. Field screening measurements
using a PID were all 0.0. The low concentrations of PCE present in the subsurface indicate that
the former drum remnants were the likely historical source of PCE in the soil and groundwater.
This area was excavated to a depth of I foot during the Shepherd Farm soil excavation in the fall
of 1997.

4 Proposed Modifications to ROD Remedy
This section outlines the proposed modifications to the ROD remedy for soils at the GE
Subsite. The modifications are proposed in response to additional information gathered since the
completion of the ROD in 1995 including data from the pre-design and intermediate design
investigations. A summary of the ROD remedy and the intermediate design investigations are
given in Sections 2 and 3, respectively.
4.1 Landfill A
Based upon the ROD definition, Landfill A is the area encompassing soil with PCB
concentrations greater than IO ppm. The area where PCB concentrations exceed l O ppm in
surficial soil at Landfill A is 0.9 acres, as depicted in Figure 3-2.
In the Preliminary Design (30%) Report (HSI GeoTrans, l 998a), Landfill A was planned
to be capped in a manner consistent with the ROD. Comments received from U.S. EPA (dated
March 11, 1998) indicated that the Agency would consider excavation of Landfill A and disposal
of the soil at the OSI. This approach would be advantageous for several reasons. First, the OSI
will require fill in order to bring it to the grades necessary to facilitate drainage of the final cap
and cover. Soil and debris excavated from Landfill A would be used to help achieve the required
grade at the OSI. Secondly, consolidating all of the contaminated soil at the OSI simplifies the
remedy and eases monitoring and maintenance activities and costs. Finally, excavation of
Landfill A allows use of the restored area without concern for O&M on the cap or potential long-
term exposure to human and environmental receptors.
The areal extent of Landfill A is presented in Figure 4-1. The area of Landfill A is 1.3
acres and encompasses all of the area where total PCB concentrations in surficial soil exceed I 0
ppm, as well as, the geophysical anomalies. Landfill A has a depth of approximately nine feet in
the area of the buried trenches and a depth of approximately three feet in the area outside the
buried trenches. The volume of soil requiring excavation from Landfill A is estimated to be
l l ,000 cubic yards. This volume estimate are based on an area of 0.5 acres to a depth of nine
feet (buried trenches) and an area of 0.8 acres to a depth of 3 feet. The volume of soil requiring
excavation may range up to 19,000 cubic yards if the entire l .3 acre area is excavated to an
average depth of eight feet. Final excavation extent and depth will be determined by
confirmation sampling for PCBs.
It is proposed that Landfill A be excavated in place of the ROD remedy of capping. The
excavated soil and debris from Landfill A will be placed in the OSI and later capped with a clay
and geomembrane cap. The OSI has more than sufficient capacity to contain excavated soil from
Landfill A. The Landfill A excavation would be brought to grade using clean fill similar to the
fill used at the Shepherd Farm excavation. This proposed modification to the ROD remedy is
equally protective of human health and the environment as the ROD remedy and provides a
permanent solution that is most practicable for this site. Furthermore, the modification is cost-
effective and will comply with all ARARs.

4.2 Landfill B
Similar to Landfill A, Landfill B is defined as the area encompassing soil with PCB
concentrations greater than 10 mg/kg. Data obtained during the pre-design investigations (HSI
Geo Trans, 1998a) activities have allowed for the areal extent of Landfill B to be delineated as
shown in Figure 4-2. The area of Landfill B is 0.1 acres.
The ROD remedy for Landfill B was capping. In the Preliminary Design (30%) Report
(HSI GeoTrans, 1998a), it was proposed that Landfill B be excavated with PCB-contaminated
soil to be placed at the OSI. U.S. EPA comments dated March 11, 1998 indicated the Agency's
acceptance of this plan due to the relatively small volume of contaminated soil at Landfill B.
The remedy proposed for Landfill B is excavation. Like Landfill A, excavation of
Landfill B will provide the fill material needed for the cap system at the OSI and will reduce
monitoring and maintenance requirements of the overall soil remedy. The excavation would be
brought to grade using clean fill similar to the fill used at the Shepherd Farm excavation. Soil
sampling performed during the Remedial Investigation (U.S. EPA, 1995b) indicates that Landfill
B has a maximum depth of three feet. The surface geophysics indicates that the maximum depth
of Landfill B is seven feet. The minimum volume of soil requiring excavation from Landfill B is
estimated to be 500 cubic yards. This estimate are based on an area of0. l acres and a depth of
three feet. The maximum volume of soil requiring excavation may reach I, I 00 cubic yards
based on the same area but with a depth of seven nine feet. Final excavation extent and depth
will be determined by confirmation sampling for PCBs.
The proposed modification to the ROD remedy is equally protective of human health and
the environment as the ROD remedy and provides a permanent solution as is most practicable for
this site. Furthermore, the modification is cost-effective and will comply with all ARARs.
4.3 Dry Sludge Impoundment
The areal extent of the OSI for remediation is defined by total PCB concentrations in the
surficial soil as shown in Figure 4-3. No significant modification to the ROD remedy is
proposed for the OSI. A multi-layer cap consisting of a flexible membrane and 18 inches of a
compacted, low-permeability soil will be placed over the OSI. A final cover of a drainage layer,
topsoil, and vegetation will control run-off and provide protection for the cap. Prior to
constructing the cap, contaminated soil excavated from Landfills A and B, as described in
Sections 4.1 and 4.2, respectively, will be placed in the OSI. This soil will be compacted in
place along with additional fill material to provide the final grades necessary for cap
construction.

4.4 Shepherd Farm
No modification to the ROD remedy is proposed for remediation of soil at Shepherd
Farm. Remedial action of the soil at Shepherd Farm has been performed. A total of7,200 cubic
yards of PCB-contaminated soil was excavated and placed in the OSI. The remedial action was
described in a draft report (HSI GeoTrans, 1998c). A final RA report that incorporates EPA's
comments on the draft report will be forthcoming.
