Warren County PCB Landfill Detoxification Project NCDENR
I. BACKGROUND
The State of North Carolina (State) constructed the Warren County Polychlorinated Biphenyl
(PCB) Landfill in 1982 to contain PCB-contaminated soil removed from roadsides in fourteen North
Carolina counties. The contamination ·occurred when liquids containing PCBs were illegally sprayed
along over 210 miles of roads. The contaminated area, known as the PCB Roadside Spills, was listed on
the National Priorities List and the removal of the contaminated soil and placement in a Toxic Substances
Control Act (TSCA) permitted landfill was the remedial action approved by the US Environmental
Protection Agency (EPA).
Construction of the landfill was strongly opposed by residents and civil rights leaders. They felt
the location was selected because of the large minority population and low income level near the site.
The community activism at Warren County was considered the "watershed event" that brought
environmental justice to the national level. A letter was written to the community by Governor James B.
Hunt, Jr., which promised the state would "push as hard as it can for detoxification of the landfill when
and if the appropriate and feasible technology is developed."
A. Selection ofTechnology
The Joint Warren County/State PCB Landfill Working Group (Working Group) was established
in 1994 to study the status of the landfill and determine the feasibility of detoxification. The group was
made up of concerned Warren County citizens, environmentalists, independent science advisors, and
representatives from state government. An extensive site assessment was conducted in 1997 and potential
treatment technologies were reviewed. The Working Group set a treatment standard of200 parts per
billion (ppb) for PCBs and 200 parts per trillion (ppt) toxicity equivalent concentration (TEQ) for
dioxins/furans and evaluated two technologies in bench-scale studies. Based on the results, the Base
Catalyzed Decomposition (BCD) process was selected as the best and safest technology for the
remediation. The process was developed by the EPA at the National Risk Management Research
Laboratory in Cincinnati, Ohio as an alternative to incineration. BCD met the Working Group's
treatment requirements in bench scale testing and fulfilled their objectives of conducting the
detoxification onsite and destroying the PCBs to prevent the contamination of other communities. The
process and treatment standards were established as statutory requirements by the General Assembly.
The Working Group completed its objectives and was reorganized into the Community Advisory Board
(CAB) with the objective to follow the project to completion.
B. Project Design
A preliminary design was prepared in 1998 for the purpose of estimating the project cost. The
North Carolina General Assembly provided additional funding for completion of a detailed design. The
detailed design was completed in March 2000. Funds were allocated by the General Assembly to start the
project and in-kind services were offered by the EPA through the Office of Technology Development to
support the effort. Grants were also provided by EPA Region 4 for outreach and training services to the
community. The State also continued support to the community by providing an independent technical
advisor and a part-time secretary to assist the CAB.
C. Selection of Contractors
Earth Tech ofNorth Carolina (Earth Tech) was hired in November of2000 to provide services to
the State for the detoxification project bidding process, contract administration, construction management,
operations oversight, and perimeter air monitoring. A qualification-based process was used to select
contractors to bid on the detoxification contract. A representative from the CAB was included in both
selection processes. Following a competitive bidding process as required by State statutes, the contract
for the detoxification project was awarded to The IT Group in January 2001. The IT Group specified that
the treatment portion of the project would be subcontracted to Midwest Soil Remediation, Inc (MSR).

Warren County PCB Landfill Detoxification Project NCDENR
II. DETOXIFICATION OF LANDFILL
The detoxification contract with The IT Group was executed in March of 2001 and a ground
breaking ceremony was held at the site on June 11 , 2001 . The ceremony was attended by representatives
of government, the community, and the press and included individuals who had been arrested during the
landfill protests in 1982.
A. Site Preparation
Site preparation was conducted from June to December of 200 I and included the following:
• Installation of erosion and sedimentation controls;
• Clearing, grubbing, and grading of detoxification project area;
• Removal of monitoring wells in detoxification project area;
• Installation of new fencing to include detoxification project area;
• Upgrade of site electrical service;
• Installation of concrete pads for soil preparation, treatment, and holding areas;
• Erection of pole barn to cover soil preparation pad;
• Application of sealant over concrete in soil treatment pad; and
• Installation of a water main from SR 1604 to landfill site.
B. Change in Contractor
In early 2002, The IT Group declared Chapter 11 bankruptcy. Work continued offsite with
permitting and equipment preparation while the bankruptcy proceeded in court. The Shaw Group
purchased some portions of The IT Group and assumed the detoxification project under Shaw
Environmental and Infrastructure (Shaw) in May of 2002.
C. Equipment Mobilization
MSR began delivery of soil treatment equipment to the site beginning in May of 2002. Shaw
delivered additional equipment that was used for storm water treatment, soil excavation, soil transfer, and
other support activities. The process train was assembled and tested with clean materials prior to the
contaminated soil treatment. An open home was held on June 22, 2002, to allow the community to see
the equipment up close. NCDENR, Earth Tech, Shaw, EPA, and MSR provided staff to conduct tours of
the treatment process and perimeter air monitoring stations and respond to questions and concerns.
D. Soil Treatment
I. Soil Excavation
The landfill was divided into three excavation cells based on approximately equal areas of the
landfill surface. The first section oflandfill cover was removed in July of2002 and stockpiled for
restoration at the end of the project. A portion of the clean cover was used for calibration and for testing
of equipment mechanical operation.
Soil was excavated from the landfill moving from the south end to the north end which
corresponding with the downward slope of the bottom of the landfill. The topsoil and fill layers of the
landfill cover were removed and stockpiled for use during site restoration (Fig. I). The top PVC liner was·
cut into pieces and disposed at the subtitle D landfill operated by Waste Management in Kernersville, NC.
Clay below the top PVC liner but above the fill layer was added to the site restoration stockpile. During
the course of the project it was determined that some of this material exceeded the cleanup limits and
required treatment. The original landfill design did not include material, such as a flexible membrane
liner, to physically separate the clay and fill layers. It was theorized that some mixing may have occurred
at the interface during the original construction which led to the contamination. EPA Region 4 was
contacted and a plan to manage this material and prevent further contamination and was developed. The
Page 2 August 2005
Warren County PC B Landfill Detoxificat ion Project NCDENR
disposition of that material is descri bed in section 11.E of this repo11. PCB-contaminated soil below the
top clay liner and above the bottom clay layer was excavated and treated.
Treated soil was returned to the landfill from the south end to the north end after excavation cells
after sampling verified a cell met cleanup requirements. An open area was maintained between the
treated and untreated soil to prevent cross contamination. Berms were also installed to prevent
contamination of treated soil by runoff from untreated soil areas. In addition, Shaw used portable pumps
to remove contaminated storm water to prevent breaching the berms during heavy rainfall. The
contaminated storm water was sent to the lined retention pond for treatment.

2. Thermal Desorption of PCBs from Soil
The techno logy selected for th e project was Base Catalyzed Decomposition (BCD) process as
shown in Fig. 2. When the process was selected, it had been successfully demonstrated on small projects
but had not been approved under TSC A or used on a project of the scale of Warren County. The process
included adding sodium bicarbonate to the soil prior to the thermal desorber.
Shaw and MSR proposed elim inating the addition of sodium bicarbonate arguing that BCD
patents described the process as --rhe embodiment of the methods as the destruction of contaminants
stripped from contaminated materials'· and was therefore not an integral part of the BCD process. Use of
sodium bicarbonate would hm e required a separate storage and control system and would have reduced
the throughput of contaminated so il in the desorber thus increasing cost. Literature published after the
Working Group selected the process indicated that the addition did not improve the removal or
destruction of PCBs in the therm al desorption unit. The laboratory studies performed during the Working
Group's evaluation included the add iti on of sodium bicarbonate but did not evaluate the effect of its use
on the process. Us ing sodium bicarbonate would have required storage and control systems and reduced
the soil processing rate. Based on th is info rmation, the request was approved.

Neither the BCD nor the thennal desorption process of MSR had been approved under TSCA and
a demonstration was required. The conditions for demonstrating the technology and operating the
equipment under TSCA regulations were established in the application presented and the approval issued
by the Fibers and Organics Branch of the EPA Office of Prevention, Pesticides, and Toxic Substances
(OPPTS) to MSR. Results of those tests were reported to OPPTS and Region 4 during the testing period.
OPPTS approved interim operations in a letter dated March 30, 2003 and included a summary of the
demonstration results (Fig. 3).

Treatment of contaminated soil began in late August of 2002 and was completed on October I 8.
2003. The State mandated residual PCB concentration of 200 ppb was the most stringent of the project
requirements and was established as the process treatment limit. It was recogni ze d that this requirement
was also close to the limit of the analytical method to quantify the concentration and that the variability of
the method would have a greater effect on acceptance at this limit. A control strategy was developed for
batch acceptance which met the requirements and acknowledged the limits of the analytical method.
Individual batches with a concentration :'S 200 ppb were accepted without question. Batches with a
concentration > 200 ppb and :'S 500 ppb were accepted if the average concentration remained :'S '.?.00 ppb
with the batch included. Batches not accepted were reprocessed through the thermal desorber. Fig. 4
shows the approved batches and running average PCB concentrations versus batch number with the State
target of 200 ppb and an upper limit of 500 ppb. Fig. 5 shows the same information versu s an upper limit
of I ppm ( I 000 ppb ). the TSC A high occupancy I im it for the site.

PCBs left the thermal desorption unit in the vapor stream from the desorber. The vapor was
condensed and allowed to separate into two layers. The organic layer contained the PCBs and was
accumulated in a tank to feed the BCD reactor. The aqueous layer was treated and then sprayed on the
treated soil exiting from the desorber to cool and hydrate the soil.
3. Post-Excavation Sampling
After the soil had been excavated from a cell, the surface of the clay liner was subdivided into 50'
x 50' grids and a composite sample obtained according to the Sampling and Analysis Plan for the project
(Fig. 6). If the results were greater than I ppm, additional material was removed for treatment until the
grid sample result was less than I ppm.
The contaminated area footprint was 420 feet by 176 feet or approximately 1.7 acres. The
sampling grid was slightly larger at 450 f~et by 200 feet to include adjacent material. Table 2 contains the
results of the final sample in each grid block.

The location of each sample location was surveyed and is shown on the drawing titled Post-
Remediation Soil Sample Locations in Appendix D.
4. Destruction of PCBs
When developing the project specifications for the detoxification contract the State had to provide
an estimated quantity of PCB contaminated oil. The estimated quantity from the PCB Roadside Spills
records was 30,000 to 35,000 gallons. This quantity was increased to 60,000 gallons for bidding purposes
due to uncertainty of the quantity and the need to have sufficient funds available for treatment. MSR
fabricated and mobilized a heated, stirred tank reactor and associated equipment that was designed based
on that amount.
Approximately 4,200 gallons of PCB contaminated liquid was collected from the process.
Review of the literature after the project indicated that a low recovery is not unusual. It has been
theorized that PCBs breakdown in the thermal desorber due to the high temperatures. It was not possible
to conduct the entire performance demonstration test in the equipment at the site with the quantity
collected. The State notified Region 4 of plans to dispose of the material using in a TSCA-permitted
incinerator. While this was not the preferred option of the community, they did agree to support this
decision after their environmental justice concerns about the available incinerator locations were
addressed, the material was sent to the OMNI facility at Port Arthur for destruction. A sample was sent to
Office of Technology Development in Cincinnati for use in pilot scale BCD studies.
E. Contaminated Stockpile
In November of 2002, the State collected samples from several areas at the project site. PCBs
were found in the clean storm water sedimentation basins both in the storm water and in the collected
sediment. Additional samples were taken from the areas that drain to these basins and indicated the cover
stockpile was the source of the PCB contamination. The material in the stockpile had been assumed clean
based on landfill construction information.
After the discovery of the problem, no additional material was added to the stockpile. The
remaining cover was divided and sampled at several depths. Approximately 1,200 tons above IO ppm was
found. The material was below the PVC top liner and could be easily mixed with the contaminated soil
during excavation which aided processing. Approximately 6,600 tons were found to be less than I 00 ppb
and were stockpiled in a clean area east of the landfill for use as final cover.
A sampling grid was imposed on the stockpile and samples taken. The stockpile was reduced by
taking lifts of approximately 2 feet, reestablishing the grid, and taking more samples from the stockpile
until clean soil was reached. Most of the stockpile was composed of clay which was more difficult to
treat. Grid blocks that ranged from 8.1 ppm to 43 ppm and totaled 417 tons were treated and the PCB
concentration reduced to 43 ppb.

2. Comparability of cerlocatcd data was very good so there were no further co-,located samples after Full-Scale Week #4.
3. No particulate samples were collected during full scale week 11, 17A, 18, and 20.
4. Starting Full Scale Weck 22 samples were collected on a biweekJy basis.
5. Due to laboratory error, samples collected 12/2/03 to 12/3/03 were not analyzed

Remediation Narrative for the Landfill Leachate Treatment
Sand Filter and Carbon Unit
While the landfill was in service leachate was pumped from the landfill. It was then
gravity flowed through a sand filter and carbon unit located on the north side of the
landfill. The sand and carbon were contained in concrete tanks.
The sand and carbon were sampled September I I, 2002 and tested for Mercury, ICP
metals, PCBs, and aromatic volatile organics. Analytical sheets are attached and the
sample results are summarized below. This sampling showed that the material was clean
except for low levels of PCRs.

The sand and carbon units were removed July 19, 2003. The lids on the concrete vessels
fell apart. The carbon unit lid was placed in the non-hazardous PCB roll-off and the lid
from the sand filter was placed in the hazardous PCB roll-off. The tanks themselves were
taken to pad I, pressure washed, then taken to pad 4 and sampled. One composite chip
sample from each tank was sent to the lab. The results are shown below.

These results were examined and approved by Earth Tech (Dennis Jones) and the two
concrete tanks were taken to the landfill, broken up, and buried August 4, 2003.
Remediation ·Narrative for the Concrete Pads
Pad Sa1nple Point Locations
As described in the sampling and analysis report the concrete slab is divided into 4 pads
numbered I through 4. Each pad is divided into sections and each section is further
subdivided into 9 grids. One sample is taked from one grid in each section. The location
of the grid is determined by a random number generator.
Each section was entered in an Excel spreadsheet as shown in Figure Pad-I. The
formular
=RAND()*S.9999+0.50000 I
was entered below each section and the output was formatted to one significant figure.
When the F9 key is entered this function generates a random number between l and 9. In
the presence of Rob Holland of Earth Tech Shaw struck the F9 key several times, then
printed the results. Earth Tech and Shaw agrcedcd that this would define the grids within
each section to be sampled.
The actual sampling grids were then drawn on each pad with dimensions that would
allow the center of the sampling grid to be located. These locations are shown in Figures
Pad-2 through P~d-5.

Remediation Narrative for Pad I
To get an advance idea of how much work would be required to decon pad l section 1-l
was deconned in early November and wipe was analyzed at 5.1
Cleaning resumed on January 31, 2004 on Pad l . Using the same methods as previously
employed on Pads 2 and 3, we used floor scrubbers, Less Than Ten cleaning solution,
and hot water pressure washers. Section I -2 was washed and rinsed twice then sampled.
This section passed with a BQL.
Cleaning resumed and the remainder of Pad l was washed and rinsed twice. Samples
were taken on the remaining 3 section on Feb. 4. One of these passed and the other two
barely failed. The site received .. over l 1/2 "of rain on Feb.6. Sections 4 and 5 were
resampled on Feb 7 and both passed. All of the sample results are included in the table
below.

The entire pad was deconed and three grids were sampled l l/20/03. One of the samples
was lost hy the lab and the other two grids were above the limit of IO ~tgm PCB/Wipe.
The entire pad was rewashed and grids I and 4 were sampled 11/24/03 . These results
were higher than the first set of results. These grids are in the area of the pad where MSR
stored centrifuge sludge.
On l l/25/03 the other 4 sections were sampled and sent to Paradigm with instructions to
analyze sections 3 and 6. These two sections failed also.
T he entire pad was rewashed using the hot water machines. On 12/2/03, Sections land 6
were sampled and sent to Paradigm. Section l passed and Section 6 barely failed. To
select random grids, Shaw returned to the original grid selection chart.
The entire pad was rewashed again using the hot water machines. On 12/6/03 Sections 2
thn.1 (j were sampled and sent to Paradigm along with a duplicate on Section 5. Section 4
passed, the other sections fail ed. To select random grids, Shaw returned to the original

was rinsed twice ;-i.nd samples taken from all sections. Sections 2, J , & 6 passed.
Sections I, 4, & 5 failed
On 12/ l 1). Sec tions I, 4, & 5 \\ ere washed again using the same proceclun; and sampled
on l2!20. Again. these sections fa iled wi th essenti ally the same numbers. It should be
noted that the area of th ese scciions was where filter press cake and centrifuge sludge
were stockpiled prior to bknding with fe ed soi ls. These materials had the highest PCB
concentrations that were encountered on the project. These results are listed on the
following table.
On 1/5/04 and li6/04, sections 1,4, & 5 were again washed utilizing the same equipment
as before. However, more of the Less Than Ten solution was applied and left in contact
with the surface longer. Section l passed while sections 4 & 5 remained above the limit.
On 1/8/04, Sections 4 & 5 were given another rinse and resampled. These sections both
passed.
This completes the decontamination of Pad 2.

Remediation Nan-ative for Pad 3
Two hot pressure washers were received and started the morning of 11/25/03. Section 3-
2 was cleaned by mid afternoon and sampled. Later observation showed that the sample
mighl have been taken in an area that had not been washed. We backed up to an area that
had definitely been washed and did a second wash. The area was wiped and the sample
was labeled W CLF-Pad2-test. There were flakes of epoxy sealer in the area that pulled
up at the edges and some came off on the wipe pad.
On 11/27/03, a sample of concrete dust was taken using a hammer drill and a carbide bit
to simulate the by product of whal shot blasting the surface might create. This dust .
sample was numbered WCLF-DS-21 I.
On 11 /29/03, we used an electric disc grinder on a I sq ft area to simulate what the
surface would be like after shot blasting . This wipe sample was labeled WCLF-DS-212.
The result of this sample was BQL.
On 12/3/03, we performed a couple of tests utilizing "Less Than Ten" cleaning solution.
Sample # WCLF-DS-218 was on an area that had been well pre-washed with a hot water
pressure washer. This sam ple location was cleaned according to manufacturers
instructions. Sample# WCLF-DS-219 was on an area that had nol been prewashed. This . sample location was cleaned according to manufacturer's instructions except it was
rinsed with a hot water pressure washer.
All of Pad 3 was rewashed utilizing the "Less Than Ten" cleaning solution applied with
commercial floor scrubbers and rinsed with hot water pressure washers. On 12115/03, all
ten sections of Pad 3 were wipe sampled. Four of the ten sections passed. The others
failed, but the overall reduction in PCB level was significant.

Remediation Narrative for Post MSR Demob
Samples ("C" Samples)
Samples 1 C through 4C were taken on 12/1 0/03 from the bottom of the lined
pond after the pond had been desludged and the liner removed . The pond liner
held up well during operations and there were only 3 small areas under the liner
that had small amounts of discolored soil. These areas were removed prior to
sampling.
Sections 1 C, 2C, and 4C had PCB limits that were BQL. Section 3C had 0.2ppm
of PCB's. All well below .the 1 PPM limit. Results are in the table below.
Samples 9C1, 9C2, and 9C.;3 were taken from the site access road running
parallel to the pads on the west.· All 3 were well below the 1 PPM allowable limit.
Results are in the table below.
Section 10C was sampled on 1/23/04 and failed at 5.5 PPM of PCB's. The area
was re-excavated and resampled on 1/27/04. This time the result was well below

Unlined Pond Sampling in 2004
Background
After the previous round of sampling and remediation of this pond (performed in 2002
and reported in Section l 0 of this narrative) the pond was used to hold treated stormwater
in accordance with the provisions of the Non-Discharge permit issued by NCDENR
DWQ. The use of the pond for this purpose was discontinued in December 2003.
Between then and mid April of2004 the water which had remained in the pond in
December had been lost to a combination of infiltration and evaporation, and the pond
was substantially dry. As a result, it was never necessary to construct the irrigation
system that had been allowed for under the Non-Discharge permit.
Initial Sampling Locations
On April 13, 2004 the first round of the Phase 2 sampling of the unlined pond was
performed. Composite samples (9 points per composite) were taken from grids SC to 8C,
as shown on Figure 2 of the Sampling and Analysis Plan ( copy of figure attached to this
narrative section).
Initial Sample Results
As shown in the attached Paradigm Analytical Laboratories Report No 0515-727, the
results of this inital round of sampling were as follows:
WCLF-DS-297-SC-0
WCLF-DS-296-6C-0
WCLF-DS-295-7C-0
WCLF-DS-294-8C-0
625 ug/kg (quantitated as Aroclor 1260)
1,670 ug/kg
554 ug/kg
1,570 ug/kg
Second round sampling locations
The results of the initial round of sampling showed that grids 6C and 8C, which
represented the southern portion of the pond, contained PCBs above the clean up standard
of l ppm which applied to this area. Rather than remove soil from all of this relatively
large area, it was decided by representatives of Shaw and Earth Tech to subdivide this
area into 6 smaller grids in an effort to isolate the area of contamination. These grids,
designated as sample locations 11 C through l 6C, were located as shown on the attached
sketch.
Based on knowledge of the use of this pond during site remediation activities, the two
most likely sources of the contamination were the outfall of the stormwater treatment
system and an area where soil from a contaminated stockpile had washed into the pond.
In an effort to limit the amount of soil requiring offsite disposal, the grids were made
unequal in size, so as to bound these two likely source areas as tightly as possible, grid
dimensions are shown on the sketch.
On April 15, 2004 composite samples were taken from each grid. The number of
individual grab sample points that went into each grid composite sample was calculated
as shown on the sketch to ensure that there was a minimum of one sample point per 300
sq. ft. of surface area within the grid, as required by section 4.2 of the Sampling and
Analysis Plan.
Second Round Sample Results
As shown in the attached Paradigm Analytical Laboratories Report No 0515-729, the
results of this second round of sampling were as follows:
WCLF-DS-298-1 l C-0
WCLF-DS-299-l 2C-O
WCLF-DS-300-l 3C-O
WCLF-DS-30 l-14C-O
WCLF-DS-302-1 SC-O
WCLF-DS-303-l 6C-O
101 ug/kg ( quantitated as Aroclor 1260)
180 ug/kg
254 ug/kg
158 ug/kg
2,420 ug/kg
252 ug/kg
These results show that the source area was located in grid I SC, which is the one that is
believed to have been impacted by the soil from a contaminated stockpile that was
washed into the pond.
Excavation, sampling and analysis
Since grid l 5C contained PCBs above the clean up standard of I ppm it was excavated to
a depth of approximately 6 inches on April 17, 2004. The removed soil was stockpiled on
a concrete pad and was subsequently shipped for offsite disposal on April 21, 2004. This
material was sent to the Piedmont Landfill Facility operated by Waste Management, Inc.
in Kernersville, NC. It was shipped under their non-haz.ardous waste manifest #20256.
Grid I 5C was re·sampled on April 18 , 2004. As shown in the attached Paradigm
Analytical Laboratories Report No 0515-732, the result was as follows:
WCLF-DS-304-l 5C-l
Unlined Pond Status
BQL (below quantitation limit)
quantitation limit reported as 40.1 ug/kg
Based on the results of the sampling described above, remediation work on the unlined
pond was complete. The locations of the final confirmation sampling points for each grid
were surveyed on April 19, 2004. The locations are shown on the post-remediation
sampling map, which is part of a separate submittal. The pond was then regraded on
April 20 -21 , 2004 so that it drains naturally to the east. The regraded area was surveyed
on April 22 , the revi sed contours are shown on the final phase 2 as-built topographic
map, which is part of a separate submittal.
As part of the regrading all inlet piping was removed. The perforated corrugated metal
standpipe wh ich had served as a discharge structure was also removed, as was its
concrete base. The 6" PVC discharge pipe which it had connected to was blocked at the
pond end prior to burying it during the regrading. The outlet end of that pipe had
previously been secured with a pipe cap to prevent discharge of potentially contaminated
.f
water. A 2" diameter hole was drilled in that cap to prevent any possible accumulation of
water in the pipe.
