1. INTRODUCTION
Confirmation Sampling and Analysis Plan
Carolina Transformer Superfund Site
Section:
Revision:
Date: 11108199
Roy F. Weston, Inc., (WESTON) has prepared this Confirmation Sampling and Analysis Plan
(CSAP) for the Carolina Transformer Superfund Site located in Fayetteville, North Carolina.
The CSAP present the strategy and procedures for confirmation sampling and analysis of the
following types:
I. Soil/sediment remaining in pits excavated to remove PCB-contaminated soil to determine
whether additional excavation is necessary.
2. Soil/sediment treated by solvent extraction to determine whether additional treatment is
necessary.
The Carolina Transformer site is located at 1434 Middle River Loop in Cumberland County,
North Carolina, approximately one mile northeast of Fayetteville, north of the intersection of
U.S. Highway 301 and Middle and River Roads. The property covers approximately 4.4 acres,
but contamination extends approximately 1600 feet off site within a drainage ditch to the
southwest. Maps of the on-property and off-property areas known to be contaminated are
provided in Figures 1-1 and 1-2.
Site contamination is believed to be a result of improper recycling, storage and management of
electrical transformers, capacitors, and PCB-containing fluids from 1967 to 1982 by the Carolina
Transformer Company. For a detailed site history and characterization, refer to the Remedial
Investigation (RI), Post-RI, Feasibility Study, and Remedial Design Data Collection Reports.
Under contract to U.S. EPA, WESTON prepared a solicitation package for the remediation of
contaminated soil, sediment, buildings, containers, and debris at the site. In April 1999, the
remediation contract was awarded to Terra-Kleen Response Group (TK). As part of their scope

of work, TK is required to excavate soil/sediment with PCB concentrations exceeding I mg/kg
and to treat this material by solvent extraction until the following is achieved:
• PCB concentrations are no greater than I mg/kg.
• Concentrations ofpolychlorinated dibenzodioxins and dibenzofurans (PCDD/PCDFs)
are no greater than 0.12 ug/kg, as measured by the toxicity equivalent quotient (TEQ).
• TCLP leachate concentrations do not exceed the TCLP limits for metals.
The purpose of this CSAP is to outline a sampling and analysis program to confirm that the in
situ soil/sediment and the treated soil/sediment meet their respective performance criteria during
site remediation.
In addition, if the benzene concentration exceeds 20 ug/kg in the treated soil, WESTON will
conduct TCLP testing to determine whether the benzene TCLP limit of 1 ug/L is exceeded. If
so, additional treatment will be required.

2. CONFIRMATION SAMPLING PROGRAM
2.1 SOIUSEDIMENT TO BE EXCAVATED
Confirmation Sampling and Analysis Plan
Carolina Transformer Supcrfund Site
Section:
Revision:
Date: I I /08/99
More than 20,000 cubic yards (CY) of soil/sediment is to be excavated at the Carolina
Transformer Site due to PCB contamination. For the purposes of this plan, "on-property"
contamination refers to remediation areas north and east of the driveway leading to the Edge
property, even though some of this area extends slightly beyond the Carolina Transformer
property boundaries. This area, which also includes ditch areas DI, D2, D3, and D4, accounts for
approximately 70 percent of the soil/sediment volume known to be contaminated with PCBs.
The on-property area was divided into grids during the RI, and this grid was maintained and
recently expanded. Most of the grid regions are 50 ft by 50 ft, but many of the grid regions
consist of other dimensions or irregular shapes due to site features. The dimensions of each of
the grid regions are provided in Table 2-1. These dimensions represent the minimum volume to
be removed from each grid region. Additional soil excavation and treatment is likely because the
extent of vertical and horizontal contamination has not been determined in many locations, and
confirmation sampling may indicate that additional excavation is necessary.
"Off-property" refers to remediation areas south and west of the driveway leading to the Edge
property. This area accounts for approximately 30 percent of the soil/sediment volume known to
be contaminated with PCBs.
No grid system was previously established for this area. To facilitate confirmation sampling, this
area has been divided into 51 regions as shown in Figure 2-1. Additional soil/sediment
excavation is also likely in the off-property area.

Revision:
Date: l l /08/99
2.2 CONFIRMATION SAMPLING AND ANALYSIS STRATEGY
After TK has excavated the soil from any particular grid region to the dimensions required (see
Table 2-1 or 2-2 for on-property areas), WESTON will collect confirmation samples from the
excavation pit for the analysis of PCBs. Depending on the location of the grid region,
confirmation sampling will include floor samples, or a combination of floor and wall samples, as
described below and in Figure 2-2.
2.2.1 Floor Samples
WESTON will collect floor samples in all excavation pits. The number of floor samples to be
collected and analyzed from each grid is summarized in Table 2-2. Sample aliquots from five
floor locations in an X pattern (the four comers and center of the excavation) will be collected
and composited. Procedures for mixing and compositing samples are provided in Section 2.4.
Decontamination of sampling equipment will be performed in accordance with U.S. EPA Region
IV guidance, as described in Section 2.5.
2.2.2 Wall Samples
WESTON will collect excavation wall samples where the neighboring soil is not targeted for
excavation. The wall samples required for each on-property grid region are shown on Figure 2-
3, and the number of wall samples required for on-property areas are summarized in Table 2-2.
Wall samples from the off-property excavation areas are shown in Figure 2-1. Sample aliquots
from five wall locations will be collected and composited. For all excavations of I 8 inches or
less, each aliquot will be collected from a depth of 2 to 6 inches from the surface. For
excavations of more than 18 inches, composited samples will be collected at depths of2 to 6

inches and from 8 to 12 inches from the surface. The deeper sample will be analyzed first; if the
deeper sample is contaminated, the shallow sample shall not be analyzed.
2.2.3 Additional Excavation Based on Results
If the analytical results indicate that the chemical concentrations in confirmation samples exceed
the cleanup criteria, TK will be instructed to perform additional excavation according to the
following guidelines:
Sample PCB Cone., Additional Vertical Additional Horizontal
Type mg/kg Excavation, ft Excavation, ft
Floor > 10 1, Same as grid dimensions
> 1 to 10 0.5' Same as grid dimensions
Wall > 10 Depends on depth of sample* 25'
> 1 to 10 Depends on depth of sample* 10'
*See Figure 2-2.
If the PCB concentration is less than or equal to 1, no further excavation will be required at that
location.
Field adjustments can be made to these guidelines, based on site features, observation of visible
contamination, and information gleaned from grids previously excavated. For example, if wall
samples with PCB concentrations exceeding IO mg/kg continually require two or three rounds of
re-excavation and re-sampling, the excavation beyond the walls of similarly contaminated pits
excavated later in the project can be increased to 40 or 50 ft. Conversely, if the subsequent
confirmation samples (after the initial confirmation samples) are consistently less than I mg/kg,
the re-excavation distance can be reduced.

2.3 SAMPLING OF TREATED SOIL
Confirmation Sampling and Analysis Plan
Carolina Transformer Supcrfund Site
Section:
Revision:
Date: I l /08/99
WESTON will collect one sample per 3,000 CY of treated soil. (These samples will be collected
in addition to the samples that TK is required to collect every 1,000 CY.) The sample will
consist of sample aliquots composited from a minimum of five treated soil batches, except for
the samples targeted for benzene analysis, which will be a grab sample. The composite sample
will be analyzed for the following parameters:
■ PCBs
• PCDD/PCDFs
• TCLP Metals
Each of these samples will be sent to an offsite laboratory for analysis (see Section 3).
2.4 SAMPLING AND COMPOSITING PROCEDURES
2.4.1 Sampling from Excavations
All soil/sediment samples will be collected using a decontaminated hand auger, trowel, or scoop.
Each aliquot will be collected within the first six inches from the ground (or wall) surface and
will be placed directly into a mixing bowl prior to mixing. The sample aliquots must be mixed to
ensure that the sample is as representative as possible of the sample media. Mixing within the
bowl will be in a circular fashion, reversing direction, and occasionally turning the material over.
This procedure should be repeated several times until the sample is adequately mixed.
Once the sample media has been thoroughly mixed, the material will be placed directly into
properly labeled, appropriate sample jars using the mixing spoon to fill each jar. Labeling
procedures are described in Section 2.5. The gloved hands of the sampling personnel will be kept
away from the sample media as much as possible while filling the jars to prevent possible cross-

contamination. The sample jars will then be placed into ziploc-type bags prior to analysis by
immunoassay kits or shipment to an off site laboratory.
2.4.2 Treated Soil/Sediment Sampling
Treated soil/sediment samples, except samples targeted for benzene analysis, will be collected by
Terra-Kleen personnel prior to transfer of custody to WESTON personnel. The method of
collection is described in Terra-Kleen's Final Remedial Action Work Plan and is repeated here
for informational purposes.
I. Treated soil samples from a group of 75 extraction vessels will be combined into three
25-vessel "treated soil composite sample aliquot" sets.
2. Three "treated soil composite sample aliquot" sets will be combined to form one "treated
soil composite sample aliquot."
3. Every extraction vessel will be sampled. The treated soil samples from the three "treated
soil composite sample aliquots" (representing 1,000 cubic yards) will be combined to
create one "treated soil confirmation sample" representing 3,000 cubic yards.
The WESTON site representative will submit this sample for analysis for each 3,000 cubic yards
treated.
Treated soil/sediment samples for benzene analysis will be collected from the piles of treated
soil/sediment without compositing. The sample will be collected from at least three locations on
the soil pile using a decontaminated hand auger, trowel, or scoop. The soil will be placed into a
bowl, but will not be mixed prior to placing into the sample jar. Instead, the soil will be placed
into a properly labeled, appropriate sample jar using a spoon to fill the jar. The gloved hands of
the sampling personnel will be kept away from the sample media as much as possible while

filling the jar to prevent possible cross-contamination. This sample will be shipped with the other
confirmatory treated soil/sediment samples to an off site laboratory.
2.5 SAMPLE LABELING PROCEDURES
All samples will be labeled according to the designation provided within this section. Each
sample will receive a distinct number that identifies the location of the sample and the matrices
collected from.
2.5.1 On-Property Excavation Soil Samples
Each on-property soil sample will be labeled according to the grid from which the sample was
collected. In addition, there will be a designation as to whether the sample was collected from the
wall or floor of the excavation. An example sample number from the floor of an excavation will
be CT-ON-27-FL where CT equals the site name, Carolina Transformer, ON represents that the
sample was collected from the on-property area, 27 equals the grid number, and FL indicates a
composited floor sample.
A sample collected from the wall of an excavation would be labeled CT-ON-27-W-l. In this
case, the W represents the wall sample and the number 1 represents the 2 to 6-inch sampling
zone. At those sampling locations where a wall sample is collected from the 8 to 12-inch zone,
the sample number will include a 2. In that case, an example sample number would be CT-ON-
27-W-2.
At some locations, the excavated grid will be expanded and will require additional sampling. In
this situation, the sample numbers will correspond to the grid that has been expanded either
vertically or horizontally. In the case where a grid has additional vertical excavation by 6 inches,
a typical sample number may be CT-ON-27-FL-A6. The FL-A6 represents the first vertical
expansion of the floor of grid 27 by 6 inches. As described in Section 2.2.6, excavation floors

may also be excavated at 8, 12, 18, or 24-inch intervals. In these cases, sample numbers would
reflect the different depth of excavation. For example CT-ON-27-FL-A12 represents the sample
collected from Grid 27 where the first one foot (12 inches) of soil beneath the original excavation
has been excavated. If there is additional vertical excavation within the same grid, then the
sample numbers would be CT-ON-27-FL-B6 or CT-ON-27-FL-B12, with B representing the
second vertical expansion of Grid 27 by either 6 or 12 inches.
A grid may also have to be expanded horizontally to ensure that contaminant levels are below the
remedial goals. For example, if Grid 27 were expanded horizontally, the corresponding
conformation sample number for the sample collected from the floor would be CT-ON-27A-FL.
The 27 A represents the new, expanded portion of the grid. All confirmation samples collected
within this new grid, whether from the floor or wall, would utilize the 27 A designation. Any
additional excavation within the 27 A grid would have confirmation samples labeled according to
the procedures described within previous paragraphs. The actual length of horizontal expansion
of the grid will be noted by Terra-Kleen in their surveying of the site.
2.5.2 Off Property Excavation Sediment Samples
Off property excavation sediment samples will be labeled using the same procedures described
in Section 2.5.1. Each off property soil sample will be labeled according to the grid from which
the sample was collected. In addition, there will be a designation as to whether the sample was
collected from either the wall or floor of the excavation. The grid numbers to be utilized in the
sample numbers are presented in Figure 2-3. The most important difference between the off
property and on property sample numbers will be the use of "OFF" to represent the off property
samples. For example, the confirmation floor sample collected from Grid 25 will be labeled as
CT-OFF-25-FL. This pattern will be used for ail off site confirmation samples and any new
samples collected as a result of changes to the grid excavation pattern will follow the procedures
described in Section 2.5.1.

2.5.3 Performance Demonstration Test Confirmation Samples
The samples collected from the performance demonstration test will be given a sample
designation number that corresponds to this special test of the Terra-Kleen system to treat
contaminated soil/sediment. The samples collected for confirmation sampling will be labeled
CT-PDT-BATCHl, where CT represents the site name, PDT indicates that the sample is from
the performance demonstration test, and BATCHl indicates that this sample is from the first
treated batch of treated soil/sediment. If there are more batches of treated soil/sediment from the
performance demonstration test, each sample would receive subsequent batch numbers (i.e.,
BATCH2, BATCH3, etc.).
2.5.4 Treated Soil Confirmation Samples
The samples collected from the treated soil/sediment will be given a sample designation number
that corresponds to the number of batches of soil/sediment that have been treated. For example,
for the first batch of 3,000 cubic yards treated, the confirmation sampling number will be CT-
TRD-BATCHl, where CT represents the site name, TRD indicates that the sample is from
treated soil/sediment, and BATCHl indicates that this sample is from the first treated batch of
soil/sediment. Future batches of treated soil/sediment would receive subsequent batch numbers
(i.e., BATCH2, BATCH3, etc.).
2.6 EQUIPMENT DECONTAMINATION PROCEDURES
Decontamination procedures to be used during confirmation sampling will be designed with
respect to the intended use of the equipment. Decontamination procedures will be conducted
prior to and post sampling activities, and in accordance with EP A/SESD Region IV
EISOPQAM.

DOCUMENTATION AND CHAIN-OF-CUSTODY PROCEDURES
All information pertinent to field activities, including sampling, must be recorded m vanous
forms. This section describes each documentation form and the information to be recorded for
each form. Each sampling team must keep detailed records of inspections and investigations,
and review notes before leaving the site.
2.7.1 Field Logbook
All information pertinent to a field activity must be entered in a bound book with consecutively
numbered pages. Entries in the logbook must include, at a minimum, the following:
• Date and time of logbook entry.
■ Weather conditions.
• Field observations.
• Log and summary of daily activities and significant events.
• Description of sample and sampling location.
■ Date and time of sample collection.

Because sampling situations vary widely, notes should be as descriptive and as inclusive as
possible. Someone reading the entries should be able to reconstruct the sampling situation from
the recorded information. If anyone other than the person to whom the logbook was assigned
makes an entry, he/she must date and sign the entry.
2.7.2 Chain-of-Custody Procedures
Written procedures must be available and followed whenever samples are collected, transferred,
stored, analyzed, or destroyed. The primary objective of these procedures is to create an accurate
written record that can be used to trace the possession and handling of the sample from the
moment of its collection through analysis.
A sample is in someone's "custody" if
• It is one's actual possession.
• It is in one's view, after being in one's physical possession.
• It is in ones' physical possession and then locked up so that no one can tamper with it.

2.7.3 Custody Transfer and Shipment
When transferring samples, the transferee must sign and record the date and time of transfer on
the Chain-of-Chain record. Custody transfers made to a sample custodian in the field should
account for each sample, although samples may be transferred as a group. Each person who
takes custody records, the number of custodians in the Chain-of-Possession should be kept to as
few as feasible.
When shipping or transporting samples to the laboratory, the following procedures will be
followed:
1. Complete Chain-of-Custody information as described in this section.
2. Include Chain-of-Custody and other pertinent forms and records with package to be sent
to the laboratory.
3. Retain a copy of the forms.
4. Mail packages by registered mail with return receipt requested or by common carrier.
5. The laboratory will return a copy of the completed Chain-of-Custody with the analytical
results.
Samples to be shipped must be packed so as not to break the package seal or locked so that any
tampering can be readily detected.

Date: I 1/08/99
WESTON will use a combination of immunoassay field analysis kits and fixed laboratory
services to analyze samples. While the analytical methods used by the fixed laboratory are
preferred, the field kits are necessary due to the quick turnaround of results required to maintain
continuous site operations.
The most time critical samples (results needed in O to 2 days) will be analyzed usmg the
Strategic Diagnostics, Inc. (SDI) PCB immunoassay kit. Ten to fifteen percent of these samples
will be split and also analyzed by the fixed laboratory for quality assurance purposes. The fixed
laboratories to be used are Pace Laboratories in Charlotte, North Carolina, and GPL Laboratories
in Gaithersburg, Maryland. Samples with PCB concentrations between 0.5 and 1.5 mg/kg, based
on the immunoassay testing, will be targeted for analysis by the fixed laboratory. For samples
with immunoassay results in this range, every effort will be made to keep the corresponding
excavations open until the fixed laboratory results are available.
Selected samples (approximately eight) will also be analyzed for PCDD/PCDFs by GPL
Laboratories. These samples will be concentrated in areas where evidence of ash or other
combustion products are observed or suspected.
3.2 TREATED SAMPLES
As mentioned in Section 2.3, WESTON will collect one performance demonstration sample, and
one sample per 3,000 CY of treated soil, for the following parameters:
■ PCBs.

■ PCDD/PCDFs.
• Benzene.
• TCLP Metals.
The samples will consist of sample aliquots composited from a minimum of five treated soil
batches, except for the samples targeted for benzene analysis, which will be a grab sample. If
the benzene concentration exceeds 20 µg/kg, an additional soil sample will be collected and
analyzed for TCLP benzene. The TCLP benzene result will be compared to the NCDENR
groundwater limit of 1 µg/L.
Samples for all of these analytes will be sent to GPL Laboratories.
