Dear lvlr, Gunn'
-
December 6, 1995
Project No, 93145,30-55
Cummings/Riter Consultants, Inc, (Cummings/Riter), on behalf of Beazer East, Inc,
(Beazer), is soliciting competetive bids and invites you to prepare and submit a cost
competitive bid for the excavation and staging of impacted soil at the Koppers Company,
Inc, Superfund Site in Morrisville, North Carolina, The scope of work is described in this
Request for Bid (RFB), The Technical Specifications and Contract Drawings provided to
you with the RFB for Surface Water and Groundwater Remediation (Cummings/Riter,
June 16, 1995) are incorporated by reference,
Scope of Work
In accordance with the Remedial Action Work Plan (Cummings/Riter, May 4, 1995), soil
with concentrations of pentachlorophenol (penta), polychlorinated dibenzo-p-dioxins, and
polychlorinated dibenzofurans (PCDDs/PCDFs) in excess of action levels are to
excavated and staged for thermal incineration, The action level for penta is 95 mg/kg,
The action level for PCDDs and PCDFs is 7 µg/kg expressed as Toxic Equivalent
Concentration (TIC) using the Toxicity Equivalency Factors presented in Table 10 of
USEPA Method 8290,
As shown on Drawing No, 4 of the final design drawings, there are three designated soil
excavation areas, The lateral and vertical extent of excavation has been estimated based
on results of the Remedial Investigation and predesign activities, At present, it is
estimated that a total of 625 cubic yards of soil will be excavated and that approximately
425 cubic yards of soil will require offsite incineration, Approximately 200 cubic yards
of soil will be excavated within the proposed excavation limits as overburden that is
below the action levels that will not require incineration and for geotechnical stability of

the excavation. Actual volumes will be dependent on field screening and post-excavation
sampling by Cummings/Riter and may vary substantially (more or less).
Immunoassay field screening will be used by Cummings/Riter to segregate impacted
material from material not requiring incineration. In general, the screening and
segregation process is as follows: ·
• Contractor will excavate an initial soil volume based upon the soil
excavation plan;
• Contractor will segregate and stage soil that, based upon existing data,
is not impacted;
• CIJromiogs/Riter will conduct post-excavation field screening for penta
at the 24 mg/kg and 95 mg/kg levels;
• Continue removing and staging all soil which exceeds the 24 mg/kg
screening level; soils which exceed 95 mg/kg will be staged for offsite
incineration; and soils with screening results between 24 and 95 mg/kg
will be staged separately;
• C.nmmiogs/Riter will evaluate by sampling staged soils that field
screening indicates are between 24 and 95 mg/kg.
• C.IJmmiogs/Riter will provide confirmation by post-excavation
sampling (both by screening and laboratory analysis) to verify
attainment of Record of Decision objectives for soils; and
• Contractor will remove additional soils, if necessary, based upon the
post-excavation screening and sampling.
Following Notice to Proceed, the contractor will be responsible for preparing a site-
specific Health and Safety Plan satisfying the requirements of29 CFR 1910.120 and a
separate Dust Control Plan for approval. During excavation operations, the contractor
will be required to monitor airborne particulate concentrations using a Miniram dust
monitor. The contractor's Health and Safety Plan will provide action levels for upgrading
levels of personnel protective equipment (PPE) based on Miniram readmgs _and other air
monitoring results. The contractor is to include assumptions regarding PPE and level of
protection with the bid submittal.

........
Backfilling of each excavation area will commence after post-excavation sampling
verifies attainment of the performance standards. Backfill material will consist of off-site
borrow and excavated soil not exceeding the action levels. The backfilled areas will be
compacted and graded to the approximate existing surface topography, blending with the
final grades of the backfilled Fire Pond area, and seeded to establish a vegetated cover.
Impacted excavated material will be temporarily staged in bermed areas. The staging
area will be approximately 50 feet by 100 feet and constructed as depicted in the attached
schematic. The liner will be covered with metal plates to prevent damage to the liner from
machinery. The staged soil will also be covered with 6 mil reinforced polyethylene
sheeting for protection of the soil from weather and to inhibit direct contact until the
staged soil is transported off-site for incineration. It is not anticitpated that the staged soil
will be stored for longer than 90 days. The original proposed staging area is indicated on
Drawing No. 4 of the final design drawings; however, since the groundwater treatment
building may be under construction during soil excavation activities, other areas may be
available for staging of excavated soils. Toe contractor's proposed soil staging areas
should be delineated in plan and submitted as part of the bid. Excavated soil that is not
suspected to be impacted shall be staged on SL'{-mil reinforced polyethylene sheeting and
protected from runon, runoff, and weather.
Equipment decontamination facilities (pad and holding tanks) are available for the
contractor's use onsite. The contractor will be required, at a minimum, to decontaminate
impacted equipment prior to handling clean backfill, between excavations, and upon
completion of handling impacted soils.
Toe contractor's scope includes loading of over the road trucks for transportation off site.
Transportation and disposal of treated soil will be completed by others.

PRE-DESIGN SAL"1PLING
Th"TERThl DATA REPORT
KOPPERS SUPERFUND SITE
i\'IORRISVILLE, NORTH CAROLINA
1.0 INTRODUCTION
A Pre-Design Sampling Program was conducted at the Koppers Company Superfund Site
in Morrisville, North Carolina in October and November, 1993. Sampling activities were
conducted in accordance with the Remedial Design Work Pl.an (RDWP), which was
developed in accordance with the December 23, 1992 Record of Decision (ROD) and the
April 21, 1993 Unilateral Administrative Order issued by the United States Environmental
Protection Agency Region IV (EPA). This Interitn Data Report (IDR) was prepared by
Chester Environmental (Chester) for Beazer East, Inc. (Beazer) to compile the Pre-Design
Sampling Program results.
The scope of work for each media for the Pre-Design Sampling Program is detailed in the
Final Remedial Design Work Pl.an (RDWP), Chester, Revised August, 1993). The
objectives of the Pre-Design sampling activities were to further delineate impacted areas,
to confirm previous data collected as part of the Remedial Investigation, and to provide
additional data for the Remedial Design.
This report is organized by media, ie., soil, groundwater, and surface water and sediment.
In addition, a section presenting the results of the quality assurance/quality control
( QA/QC) program, instituted as part of the sampling program, is included. The following
media specific sections present the objectives of each segment of the Pre-Design Sampling
Program, describe the field sampling program, and present the analytical results. All
analytical results are validated according to EPA Data Validation National Functional
Guidelines. The appropriate data validation qualifiers have been affixed to the data. The
quality of the generated data is assessed in the QA/QC section.

2.0 SOIL SAl\'IPLING
2.1 FIELD SA.c'1PLING PROGRAM
In accordance with the Statement of Work (SOW) and the Reme!™1 Design Work Plan
(RDWP), additional soil sampling was perl'ormed in the former lagoon (Sample Area 1)
and Cellon process areas (Sample Area 2). The purpose of this additional soil sampling
was to collect pentachlorophenol data to identify soil areas and to determine volumes for
the Remedial Design.
2.1.1 Scope of Work
As presented in the RDWP and associated Field Sampling Plan (FSP), the scope of work
for field sampling activities involved:
• The location of the sample area boundaries and designated sample
locations by survey,
• The collection of designated soil samples,
• Field screening of soil samples via immunoassay testing for
pentachlorophenoi
• The selection of soil samples for laboratory pentachlorophenol analysis
based on field screening, and
• Expansion of the sampling grids as necessary, based upon the results of
the field inumm<1assay testing.
A field QA/QC audit was also perl'ormed during the soil sampling activities to ensure
compliance with the RDWP. In addition, field QA/QC samples were collected and
analyzed.
2.1.2 Field ~Iethods
The soil sampling activities were performed by Chester personnel during the period
between October 11 through October 17, 1993. The sample area boundaries and random

starting locations were SUIVeyed the prior week. Fallowing sampling activities, all soil
boring locations were SUIVeyed by a North Carolina registered land survey.
Sample Locations: According to the sampling plan developed for the RDWP, as depicted
in Figures 4-5 and 4-q, twelve (12) soil boring locations were assigned on a square grid
spacing of35 feet Mthin Sample Area 1, and twenty-five (25) soil boring locations were
assigned on a square grid spacing of 26 feet within Sample Area 2. Soil boring locations
were assigned numerical identifications ofX200 through X2 l l in Sample Area 1 and
X212 through X23 6 in Sample Area 2.
During the assignment of soil boring locations within Sample Area 2, three perimeter soil
boring locations were reassigned due to the actual location of the Fire Pond shoreline.
Figure 2-1 depicts the deleted locations and the current perimeter of the Fire Pond
shoreline. These three locations were reassigned within Sample Area 2 at the locations
subsequently identified as X214, X233 and X236 on as shown on Figure 2-1.
Additional soil boring locations were established and sampled based on field testing results
for pentachlorophenol The basis for additional sampling was presented in the RDWP and
associated FSP. A total of thirteen (13) additional boring locations were established and
sampled in Sample Area 1 (X237 through X247, and X249 through X250). One additional
boring location was established and sampled in Sample Area 2 (X248). Figure 2-1 depicts
an the soil boring locations completed during the soil sampling program.
Sample Collection: As presented within the RDWP and associated FSP, soil samples
were collected at four depth increments (0 to 2 feet, 2 to 4 feet, 4 to 6 feet and 6 to 8 feet)
at an soil boring locations in Sample Area 1 (with the exception ofX249 and X250 which
were sampled for the 0 to 2-foot interval only), and at two depth increments (0 to 2 feet
and 2 to 4 feet) at an soil boring locations in Sample Area 2 (with the exception ofX218
and X224, where hand auger refusal was encountered at 2.5 feet). Soil samples were
assigned identifications according to the soil boring location (X.11/1."/) and depth-(A = 0 to 2
feet, B = 2 to 4 feet, C = 4 to 6 feet, D = 6 to 8 feet). For example, the 2 to 4 foot soil
sample at boring location X202 was identified as X202B.

Soil samples were collected urili.zing hollow-Stem augers and split-spoon samplers at the
majoriry of sampling locations. Hand augering was utilized to collect soil samples at
locations that were inacceSSI"ble to the drilling rig. All sampling equipment was
decontaminated prior t~ use at each sampling location in accordance with the procedures
defined in the RDWP and FSP. During soil sample collection, the on-site geologist logged
subsurfice conditions, performed phcitoionization screening of soil samples, and recorded
observations for each sample location in the assigned field log book.
Following sample collection, soil over the 2~foot interval at each sample location was
homogenized, split and contained in two separate containers. New I-Chem, Series 3000,
QA/QC certified, 8-ounce glass bottles with Teflon-lined lids were used to contain soil
samples for laboratory analyses. New, clean, 4-ounce glass bottles with Teflon-lined lids
were used to contain soil samples for field testing. All sample containers were labeled and
immediately placed on ice following sample collection. The samples remained under chain-
of-custody at all times.
Following collection of soil samples, field immunoassay testing using Ensys, Inc.
PentaRisc kits was performed to screen for the presence ofpentachlorophenoL As
descn"bed in the RDWP and FSP, the results of the immnnn~ssay testing for
pentachlorophenol were used to determine further sampling requirements and to select soil
samples to be shipped to the laboratory for pentachlorophenol analysis.
At boring locations where field testing for pentachlorophenol indicated concentrations
above 95 mg/Kg in the terminal soil sample (8 feet in Sample Area 1 and 4 feet in Sample
Area 2), an additional depth sample was collected. Depth sampling at a boring location
was terminated when immunoassay results were less than 95 mg/Kg. At perimeter boring
locations where pentachlorophenol was detected by imunmnassay testing above 95 mg/Kg
at any depth interval, additional boring locations were determined and sampled in
accordance with the RDWP and FSP. Figure 2-1 depicts the soil boring locations
completed in Sample Areas 1 and 2.
Quality Assurance/Quality Control: QA/QC procedures, as detailed within the RDWP,
FSP and Quality Assurance Project Plan ( QAPP), were adhered to during the
implementation of the soil sampling program and subsequent laboratory analyses.

A field QA/QC audit was conducted during the implementation of the field soil sampling
program The audit was performed to ensure compliance with the sampling and
decontamination procedures and site health and safety requirements of the RDWP and
FSP.
Analytical 1l1ethods -Field Testing: The field immunoassay testing for
pentachlorophenol was performed using Ensys, Inc. PentaRisc test kits. A discussion of
the test method employed (EPA proposed Method 4010), Standard Operating Procedures,
and QA/QC related to the field testing is descnbed in detail within Attachment C of the
QAPP developed for the field sampling program
The field testing for pentachlorophenol was performed at two detection levels. Each soil
sample was analyzed and compared to 24 mg/Kg and 95 mg/Kg standards. Simplified, the
on-site pentachlorophenol analysis was performed according to the· following procedures:
• Extract a 10 gram sample of soil with methanol;
• Filter extract;
• Prepare necessary dilutions to obtain 24 mg/Kg and 95 mg/Kg
detection levels;
• Add the diluted sample to antibody coated tubes;
• Initiate color development; and
• Measure the semi-quantitative concentration of pentachlorophenol
using a differential photometer.
Results were recorded on Ensys, Inc. supplied log sheets (Appendi'{ A).
Laboratory Analysis: Laboratory analysis was performed on soil sample by EPA Method
8270 for pentachlorophenol quantification only. Laboratory procedures were performed in
accordance with the RDWP, FSP and QAPP for the project. All laboratory
pentachlorophenol data generated were validated according to the QAPP.

Ensys, Inc. PentaRisc immunoassay test kits were used for field analysis of
pentachlorophenol Detection limits of24 mg!Kg and 9_5 mg/Kg were used to determine
the need for additional soil sampling activities and to designate samples for laboratory
analyses. All soil samples with immunoassay results greater than the 24 mg/Kg detection
limit were shipped to the laboratory for pentachlorophenol analysis. Ten percent of soil
·'
samples Mth. imrrnrooassay results less than 24 mg!Kg were also submitted to the
laboratory. A summary of the field immunoassay testing results for pentachlorophenol is
presented in Table 2-1.
2.2.2 Laboratory Results
Based on the results of field immunoassay testing, a total of 44 samples exceeded the 24
mg/Kg detection limit, and were submined to the laboratory for pentachlorophenol
analysis. The remainder of soil samples submined for analysis included 10 percent of those
samples Mth. field immunoassay results less than 24 mg!Kg, and blind duplicate samples.
Table 2-2 presents the validated and qualified laboratory results for the soil samples
submitted for pentachlorophenol analysis. Only nine (9) samples were above the site
cleanup level of 95 mg/Kg.
2.2.3 Geotechnical Results
Undisturbed Shelby tube samples were obtained from clayey soils at boring locations
X2.27 and X2.47. Soil boring X2.27 is located within the former Cellon process area and
boring X2.47 is located in the former lagoon area Figure 2-1). Geotechnical analysis of the
samples was performed by Trigon Engineering Consultants, Inc. For each sample the
following tests were performed:
• Grain size analysis,
• Moisture content,
• Anerberg Limits,
• Permeability testing, and
• Triaxia.l testing.
The geotechnical characteristics of the soils encountered during the soil sampling program
compared well to the geotechnical information presented in the RI report. A summary of
the geotechnical results is presented in Table 2-3. Laboratory data are provided in

4.0 SOlL RE?v!EDlATION
The development of the soil remediation portion of the Remedial Design (RD) will
involve pre-<lesign tasks necessary to collect and evaluate analytic::tl and
geotechnic:tl data to support the subsequent design phase. Based on a review of the
existing data for the former Ce!lon process and lagoon areas of the site, a sampling
design and evaluation program have been established with,in this work plan to
delineate the area to be remediated. A comprehensive description of the approach
and components of the RD requirementS follows.
According to the ROD and SOW, the primary :source comrol remedy will be
excavation and off-site inc'.ner:i.tion of the affeci{d soil within the former Cellon
process and lagoon are:i. of the site. EPA wii(::C:6nduct a tre:i.tability study to
evaluate the use of the contingent source controlJ~fuedy, on-site base c:i.talyzed
dechlorination. However, the final solltce ~;rit;~f remedy has not yet been
established. Either remedv will recuire \he: ·.e:i:c:i.vation of soils and that the
excavated are:i.s be backfiiled _wiih' deo.ri\ soil (unimpacted soil for off-site

inc'.neration and treated soil for.BCD); regrirded and revegetated. Therefore, in the
development of this work p1an;··disc:J!i;ion of items dependent upon the final source
control remedy have been 'ileferied_ This work plan will require subsequent
modification or amendm;~t to ~tldress the final source control remedy.
Remedial Action (RA)\gtials):ia.ve been established for soils in the ROD. Surface
and subsurface soils that dih{am concentrations of pentachlorophenol gre:i.ter than
95 mg/Kg and concentration of PCDDsfPCDFs greater than 7 ug/Kg ( e:i:pressed as
TECs) are to be excavated from are:i.s in the former Cellon process and lagoon
areas of the site, and prepared for on-site treatment or off-site incineration. These
remediation goals were derived to be protective of groundwater quality and have
been shown in the Baseline RA (ENSR 1992) to be protective of human health.
Potential action-spec'.fic and chemical-spec'.fic ARAR.s applicable to the soil
remediation portion of the RD have been investigated and are presented in Tables
4-1 and. 4-2, respectively. Tne ARARs are listed according to federal and state
regulations and requirements associated with excavation, storage, transportation,

former Ce!lon process and lagoon are:i.s of the site.
4-1 Initial Evalu:i.cion
Prior to design phase of tl::e RD, a review of the eJting soil data for the site and
identific:i.tion of additional data requirements his.· bee.i necessary. Tne following
re•riew summarizes data generated dur'.ng the coir.predon of the RI/FS. Based on
knowledge of the oper:i.tion of the former site pr~~esses and on data obtained
during the RJ, additional analytic:i.l ani( g~~cechnic:J.! data needs have been
established to support the deve!opme:u of the R.IJ. To obtain the additional data; a
comprehensive sample design, pre:di~i~d u9on valid statistical methodology, has
been prepared to callee: soil samples fo{~yses. Sampling will also be conducted
to obtain additional geotecbni~:tl daciL
4.1.1 Exfsting DatiEv~Juation
Analvtic:il Data
During the RI conducted for the site, a comprehensive soil sampling and analysis
program was completed over several are:J.S at the site. Surface soil samples were
collected from the ground surface to a depth of two feet, upper subsurface samples
were collec:ed from the interval of two to six feet, and lower subsurface samples
were those collected at depths greater than six feet.
Results of these soil analyses indicated that pentachlorophenol was identified above
the 95 mg/Kg cleanup standard in surface and upper subsurface soil samples
collected only from the former lagoon and Ce!lon process areas. Of the soil samples
collec:ed from the former landfarm area, the eas,em area, the western are:i. and

background locations, all penuchloropheno[ results were well below the 95 mg/Xg
cleanup level.
Select soil samples from one background loc:ition and areas of the site where
pentacltlorophenol was reported in the soil were also analyzed for PCDDs/PCDFs.
In addition to one background sample, seven surface soil samples were analyzed for:
PCDDs/PCDFs. Within the are:l.S to be addressed during the RD, PCDDs/PCDFs
samples were collected at borings X-17, X-18, X-19, X-23, X-50, X-54, X-56, X-57,
and X-58 from within the former lagoon area and borings X-43, X-49, X-53, and X-
5 5 within the Cell on process are:i.
Tne analytical data for all individual PCDD/PCDF congener concentrations were
used to calc-.i.late 2.3,7,8-TCDD toxic equivalent concentrations (TECs). Tae TEC
for individual PCDD/PCDF congeners were calc-.i.lated by using the toxic equivalent
fac.:or (TEF) method established by EPA Tne various individual PCDD/PCDF
congeners are assigned a TEF value relative to the 2,3,7,8-TCDD congener, wiri6
has a TEF of 1. All other PCDD/PCDF congeners have a TEF less than 1. Soil
quality data for all PCDDs/PCDFs are reported in toxic equivalent concentration
(TEC). Tne results of PCDD/PCDF analysis as well as pentachlorophenol for
borings in the former lagoon and process area are shown on Table 4-3.
Fonner La2oon Are!!.
Figure 4-1 presents soil quality data for pentachlorophenol and PCDDs/PCDFs in
the former lagoon area, as the lagoon area was delineated during the RI. Soil
quality was charac:erized by the analytical results from borings X-15 through X-27,
X-50, X-54, and X-56 through X-61.
Although detectable levels of pentachlorophenol were measured in eleven of twelve
surface soil samples (0 to 2 feet interval.) collected in the former lagoon area,
pentacltlorophenol was measured at concentrations above the site-sped.fie goal of 95
mg/Kg in only three surface soil s=ples. Pentachlorophenol concentrations of

3,220 mg/Ki 1,850 mg/Kg, and 438 mg/Kg were me:.isured in surface samples
collected from X-25, X-26 and X-50, respectively. Boring X-25 w:is !oCJ.ted in the
vicinity of the former sand filter and boring X-50 was loc:ited in the immediate are:i
of former southern lagoon. Boring X-26 was loc:ited along the overflow drainage
path 10 the Fire Pond. Pentacb.lorophenol concentrations were below the 95 mg/Kg
cle:!Ilup level in the ri-roaining suriace soil samples_co!Iec::ed from the former lagoon
are:t.
Of twenty-<!ight (28) upper subsurface soil samples collected from the former lagoon
area, pentachlorophenol was measured in concentrations above clewup level in
only one sample. Pentacbloropheno! was reported at a concencr:ition of 560 mg/Kg
in the upper subsurface sample collected from boring X-50, which was drilled
immediately adjace:11 to one of the former lagoons. With the exception of the
samples collee!ed from borings X-50 and X-57, detec::ed pentacb.lorophenol
concentrations in 12 subsurface samoles ranged from the minimum detec::ed
concentration of 0.050 mg/Kg at loc:ition X-58 to 7.43 mg/Kg at loc:i.tion X-21. Tne
upper subsurface sample at X-57 had a concentration of 46.4 mg/Kg, which is below
the 95 mg/Kg cle:l.Ilup sundard.
Ce!lon Process Area
Tae loc:itions of soil samples collected within the Cellon process area are shown in
Figure 4-2. Ce!lon process related scructures that have been loc:ited in reference to
remaining strucmres from aerial photographs include the former pentacb.lorophenol
wood treating cylinder and the sand filter. Soil quality is characterized by the
analytical results from borings X-28 though X-37, X-48, X-49, X-51, X-52, X-53, and
X-55.
Three surfac: soil samples were collected for analysis from within the Cellon
process area. Tae surface sample from boring X-48 (0 to 2 feet) collected at the
former location of the door of the wood treating cylinder was the only sample to
have a pentachlorophenol concentration (1,680 mg/Kg) exceeding the 95 mg/Xg
pentachlorophenol cleanup standard. Detec-..able pentachlorophenol concentrations
at other surface soil sampling loc:itions in the former Ce!lon process area were well

below the 95 ·mg/Kg cleanup level Tae upper S'.ibsurface soil sample collected at
loc:i.tion X-4S (2 to 4 feet) h.ad a reported penmcblorophenol concentration of 191
mg/Kg, whicb. is also above the cleanup s,andard.
In the Cellon process are:1. only the X-43 samples exceeded the cleanup st:l.Ildard in
the surface and upper subsurface samples. Two boring loc:i.tions to the e:ist ·and
topogr:i.phic:i.lly downgradient of the X-43 boring had nondetec+..able to relatively
low levels of pentachloropheno~ indic:iting that soil quality in the area between the
C'Jlinder and drip trac.'{ to the Fire Pond did not receive overland flow. Toe
pentachlorophenol concentrations in the r,•maioing samples collected to the south
and west of the brick building in this area were below the soil cleanup level.
Se!ec: soil samples from the areas of the site where pentacb.lorophenol was reported
in the soil and one background loc:ition were also analyzed for PCDDs/1'CDFs. In
addition to one bad:ground sample, se•,en surface soil samples were also analyzed
for PCDDs/}'CDFs. Toe higher calC'J.lated TEC values were reported for the
samples collected from the former loc:ition of the wood treating C'/linder. Total
TEC of 270,000 ng/kg (270 ug/kg) reported for the samples collec:ed from X-48 (0
to 2 feet) was the only sample to exceed the PCDD/1'CDF TEC cleanup s,andard.
T.ae sample from X-49 (O to 4 feet) contained a 4,000 ng/1,g PCDD/}'CDF TEC,
whicb. is less than the 7 ug/kg (7,000 .ag/kg) cleanup standard. For five subsurface
soil samples within the Ce!lon process are:1. TECs ranged from 11 ng/kg to 3,600
ng/kg at X-48. Total TECs c:ik..ilated for surface soil samples collected from
loc:itions in the former lagoon are:1. X-23, X-50 and X-57, were reported as 2,200
ng/kg, 2,700 ng/kg and 630 ng/kg, respec:ively. Toe six subsurface soil samples
collected within the former lagoon area ranged from 2 ng/kg to 730 ng/kg at X-57.
A statistical evaluation of R1 soil data having both pentacblorophenol and
PCDD/PCDF detections was conducted using the Geo-EAS (Geostatistical
Environmental Assessment Software, U.S. EPA, 1991) software pac.'{age. Toe
purpose of the evaluation was to • determine the correlation between
pentacb.lorophenol and PCDD/PCDF results. Toe correlation may be useful for
screening or supporting determinations that PCDD /PCDF remediation goals have
been met based on pentachlorophenol data.

Geo-EA.S employs a bi-variate statistic:tl comparison of variable pairs of
concentrations using regression analysis. Figure 4-3 is a graphic:tl presemation of
the comparison of pentachlorophenol concentrations versus the PCDD/PCDF
TEC.S. The regression analysis determined a correlation coefficient of 0.79 for these
data. 1bi.s correlation of pentachlorophenol and PCDD/PCDF TECs will be
further evaluated during RD preliminary data evaluation to determine its usefulness
as a predic::ive tool during the RA.
Geote<:hnical Data
During the RL soil samples from various lootions and depths were tested to
determine geotec::mid propemes. Tne geologic profile for the site consists of
approximately 12 feet of fine-grained clay and silt with isolated len.ses of sand
underlain by weathered bedroc:'-Tne samples were obtained from depths of O to 12
feet.
Table 4-4 su=arizes the laboratory results presented in the RI Report. Tne tests
performed on these samples consisted of grain size analysis with hydrometer testing
for fines (7 tests), Atterberg Limits (7 tests) moisture content ( 12 tests), unit weights
(12 tests), and permeability (9 tests).
Toe laboratory testing indiotes that the site soils are fine grained. Each of the
samples had greater than 97 percent of the sampled material passing a #200 sieve.
There was very little to no gravel or sand sized partic.!es observed in the site soils.
Tne soils tested were c.!:i.ssified as CL-;yll.., Nll.., CL, or CH using the Unified Soil
Oa.s.siii.otion System (USCS).
Tne Atterberg Limits testing is a measure of the degree of plastid.ty of the material.
Due to the high content of clay, the soils are e.-q,ected to be cohesive. Based on
existing data, the soils should provide adequate cohesive strength to allow shallow
excavation without extensive support. When dried, soils tend to bre1.'< into clods
due to the soils shrink-Sl'lell tendency, and form hard lumps. Standard penetration
tests (STP) values a,..ained from the borings and mooitodng wells determined that

these soils ar!= stiff to very stiff suggesting that a stability problem is not likely for
shallow e:cc:ivations.
The natural moisture content of the tested materials varied from 10.1 to 36.0
percent for depths of O to 12 feet Tne average wet unit weight of the samples tested
· was approximately 125 pounds per cubic foot. From this number the bulk unit
weight of material is estimated to be about 1.7 tons per c-..ibic yard. Since soils
increase in volume during e.i:c:ivation ( due to an increase in void space) an
estimated swell factor for the c!ay content of 40 percent would result in a load fac::or
of about 0.72. Tnerefore, a loaded density of about 12 tons per c-..ibic yard is
expected. Tne results of permeability testing of the soils ranged from 3.01 x 10-s to
1.80 x 10-S =/sec. Tne average permeability of soils is 1.1 x 10-S =/sec.
Tne e:cisting geotechnical data indicates that the variability of the soils is quite small
at depths from zero to twelve feet, however, some boring logs show other soil types
such as sand in the shallower zones and weathered bedrock in the deeper bor'...ngs.
Although sand and weathered bedrock were observed in the field, these samples
were not tested during the RI to determine geotec:inical properties.
4.1.2 Additional Data Nffiis
Analvtic:il Data
The SOW for the RD requires that additional soil sampling be conducted during the
RD in the former lagoon area and Cellon process area to identify soil areas and
volumes requiring e.i:cavation for remediation purposes. An appropriate statistical
evaluation method is to be used to evaluate the soil sampling data collec:ed in the
RD delineation. Details regarding the s-..aristical approach to sampling and data
evaluation are presented in Sections 4.1.3 and 4.1.4.
Three potential areas e:cist where pentachlorophenol concentrations are above the
soil c!eanup threshold. These plant features and area boundaries, as shown in
figure 4-4 include the former Cellon process area, the former la2oon area, and an
0 '

area between that includes the sand filter area and the drainage area from the
southwestern lagoon to the Fire Pond. To collect additional samples during the RD,

4.0 SOIL REl\iIEDLc\.TION
According to the ROD and SOW, the primary source control remedy will be excavation
and off-site ,incineration of the affected soil within the former Cellon process and lagoon
areas of the ·site. However, the US EPA conducted a treatability study to evaluate ihe use
of the contingent source control remedy, i.e., on-site BCD. Based on the preliminary
results of this study, the US EPA has indicated that on-site BCD will be used as the soil
remedy. Nevenheless, incineration will still be considered an option if the operating
conditions are significantly different than those employed during the SITE demonstration
or if the volume of impacted soil turns out to be substantially different than what is
expected. This section provides a review of predesign data, discusses the procedures used
to detennine the volume of soil requiring treatment, describes the remediation strategy to
be used to address impacted soils, and discusses the plans, specifications, permits and
access issues relative to this prefinal design stage. A design strategy for proceeding with
the soil removal such that the volumes are defined prior to making a final determination
on the treatment vendor is included in this section.
Remedial action goals have been established for soils in the ROD. Surface and
subsurface soils that contain concentrations of penta greater than 95 mg/kg and
concentrations of PCDDs/PCDFs greater than 7 µg/kg (expressed as TE Cs) are to be
excavated from areas in the former Cellon process and lagoon areas of the site, and
prepared for on-site treatment. These remedial action goals were derived to be protective
of groundwater quality and have been shown in the Baseline RA (ENSR 1992) to be
protective of human health.
4.1 DATA SUM;v!ARY
The reported concentrations of penta and TE Cs of dioxins and furans in the site soils have
been reviewed. Penta data resulted from the analysis of samples collected during the R1
and predesign investigation. All of the analyses for TE Cs of dioxins and furans (total
PCDDs/PCDFs) were performed during the Rl. Laboratory analyses of samples for penta
were performed during each phase using USEP A Methods 8040 and 8270 (USEP A, 1986).

Field screening analyses for penta were performed during the predesign investigation.
The field screening analyses were conducted using Penta Rise™ soil test kits developed
by EnSys, Inc. The Penta Rise TM soil test method is a field-based immunoassay test
specific for penta. The technique is designed to provide an accurate semiquantitative
analysis for the presence or absence of penta at various concentrations in soil.
4.1.1 Analytical Data
Figure 4-1 presents a histogram of laboratory-determined concentrations of penta in the
site soil of the former lagoon and Cellon process areas. Only about 5 percent of the 264
samples collected from 256 locations exhibited concentrations in excess of the 95 mg/kg
remedial action goal specified in the ROD. Where duplicate laboratory data existed, an
average value was used. Note that the concentration axis of the figure is logarithmic,
which tends to dampen the skewness of the distribution of penta concentrations. Skewed
concentration distributions are commonly found in assessments of impacted soil
(Flatrnan, et al., 1985; Gilbert and Simpson, 1992; Isaaks, 1984 and J9urnal, 1984).
The histogram of concentrations from the 16 samples analyzed for the total
PCDDs/PCDFs is presented on Figure 4-2. All of these 16 samples were collected during
the RI. Only one of the 16 samples exhibited a concentration greater than the 7 µg/kg
remedial action goal specified in the ROD. This sample (Sample No. X-48, zero to two
feet) also exhibited an elevated concentration of penta
A useful tool in data interpretation for this site is supplied by the "Box and Whisker" plot.
An example of this type of plot is shown on Figure 4-3. The Box and Whisker plot
permits illustration of the variation as well as the central tendency of data grouped
according to a common characteristic. The extremes are represented by the whiskers of
the plot. The edges of the box represent the upper and lower quartiles. The median, or
5 0th percentile, is represented by a line through the box. The average, or mean, of the
data is represented by an 'X'. Frequently, the mean lies outside the box because of the
great influence of extreme values on its calculation.
Figure 4-4 illustrates the distribution of penta soil concentrations as a function of sample
depth. The dotted line in this figure represents the remedial action goal of 95 mg/kg.

Note that aside from a few extremes, the penta concentrations decrease with increasing
sample depth. The samples showing these exrreme concentrations tend to cluster in site
Sample Areas l and 2 (Figure 3-1).
4.1.2 Predesign Investigation Immunoassay Field Screening
A rapid and accurate method for field determination of whether soil concentrations are
above or below the remedial action goal has two distinct advantages. The first is to fill
any data gaps in determining the volume of soil required for remediation. The second is
the ability to quickly and efficiently assess when remediation of an impacted area is
complete. The data generated from paired Penta Rise™ soil tests and laboratory analyses
provide evidence that the field-based immunoassay test, with proper utilization, provides
such a method.
Immunoassay test results were reported for 171 samples collected during the predesign
investigation. A comparative laboratory analysis was performed on 66 of these samples.
The laboratory result when available was used in the geostatistical analysis to determine
the location and extent of the area to be remediated. Of the 66 paired laboratory samples:
• 4 7 -Laboratory samples confirmed the field screening results.
• 17 -Laboratory samples reported lower penta concentrations than the
field screening results (false positive).
• 2 -Laboratory samples reported penta concentrations >95 mg/kg
when field screening indicated the penta concentration was between 24
and 95 mg/kg (false negative).
In summary, 64 of 66 field screening results (97 percent of samples) that were checked by
laboratory analysis yielded acceptable results and two yielded false negatives.
Of the I 05 immunoassay results that did not have a paired laboratory analysis, I 04 were
reported to be less than 24 m/kg and one result was reported to be greater than
95 mg/kg.

1igure 4-5 illustrates the distribution oflaboratory determined pema concentrations for
the three possible outcomes of the field-based immunoassay test. Clearly, if the
iknunoassay test indicated a concentration less than 24 mg/kg, the paired laboratory
rtult is less than 24 mg/kg. It is apparent that the immunoassay test is inclined to yield
fLse positive results. In all but the two cases mentioned above, when the paired
1Jboratory result was ITTeater than 95 mdkg the immunoassav test indicated
cbncentrations greater-than 95 mg/kg. The-se data indicated ;hat field screening for pema
d\Jring remediation can be performed with a high degree of certaintv that impacted soils
I ---.
would be excavated.
I
1/wo samples designated as between 24 and 95 mg/kg by the immunoassay test showed
rfsults greater than 95 mg/kg from the paired sample submitted for laboratory analysis.
Both of these analvses could be a result of actual concentration variation within their
r~spective boring ~ection. Caution must be used in interpreting the paired immunoassay
+d laboratory analyses of penta. The samples in question came from Borings X-206 and
X-205; these borings are less than 35 feet apart.
I
Toe concentrations with depth at these borings indicate a rapidly changing concentration
Jadient. The results are not at all inconsistent if the sample from a core section was not
jompletely homogenized prior to selection of the aliquot for analysis.
The propensity of the immunoassay test to give false positive results does not limit its
+ility for use in confirmatory sampling. Because there is little tendency of false negative
results, an immunoassay test result of less than 95 mg/kg suggests that remediation has
~een achieved or is not necessary. In order to avoid unnecessary remediation. however.
I
. .
an immunoassay test result of greater than 95 mg/kg may be followed by laboratory
donfirmation. In addition, soils indicating penta concentrations between 24 and 95 mg/kg
111 be staged separately and analyzed as described under the excavation plan.
I Prior to inclusion of these results in the geostatistical analysis, a concentration value was
:issig~ed at random from the appropriate statistical distribution of concentration data.
I Separate statistical densities of concentration were estimated for each category of field
icreening results, e.g., <24 mg/kg, 24 to 95 mg/kg and >95 mg/kg. Estimation of these
densities was conducted using the paired analyses data. This assignment of concentration

preserves the observed distribution of concentration at the site. Such an assignment has
do effect on estimation of the probability that a concentration is in excess of tile 95 mg/kg
rrmedial action goal specified in the ROD.
4.1.3 Screening Evaluations by USEPA
I
9unng the treatability studies, USEP A, through its support _contractor PRC
1nvironmental, conducted an evaluation of five technologies for analyzing pema in the
field. These technologies included:
• Penta Riser" Test Kits (EnSys, Inc.);
• HNU-Hanby Environmental Test Kits (HNU Systems);
• Envirogard PCP Test Kits (lvlillipore, Inc.);
• PCP Rapid Assay (Ohmicron Corporation); and
• Field Analytical Screening Program (F ASP) Method (USEPA
Superfund Branch).
e effectiveness of these field screening technologies was to be evaluated by
I \J assessing the precision, accuracy, cost, and range of usefulness of each technology;
1J assessing the data quality objectives that each technology is capable of meeting; and
3) comparing data obtained using each technology to the data obtained by the
Jomparative laboratory using standard USEPA methods for penta analysis. The final
Jesuits of this evaluation are not available at this time. Given the data reviewed for the
I Penta Rise'™ test kit as part of the predesign investigation, field screening methods using
&ese kits will be considered for use during remediation.

f-1.4 Mapping
rite survey and mapping information has been compiled into the site base map. This
base map is used to depict site features as well as components of the remedial action. The
f ite topography was developed based on a 1986 aerial topographic survey. Site
topography in the area of the ponds, the former lagoon, and Cellon area, as well as
~eatures such as culverts and utility poles, was updated in October 1993. The map also
hepicts the location of powerlines and property boundaries. As part of the predesign
I investigation, new and existing soil sample locations in the former lagoon and Cellon
1areas were surveyed. All surveying was performed under the direction of a licensed

North Carolina surveyor and in accordance with the North Carolina State Plane
:Coordinate System and USGS datum. The revised topographic map is included with the
construction drawings as part of this design submittal.
t2 DESIGN CRITERIA
/lhe existing data indicate that some soils in the vicinity of RI Borings X-25, X-26, X-48
and X-50 exceed remedial action goals. Data collected during the predesign investigation
~ermitted further definition of the soil volume. Figures 4-6, 4-7, 4-8 and 4-9 were
lieveloped based upon visual inspection of the soil data and show approximate areas
/where sampling indicates that soils exceed remedial action goals at zero to two feet, two
to four feet, four to six feet and six to eight feet, respectively. The data do not lend
bemselves to contouring so the data are presented and approximate areas requiring
~emediation are shaded.
I
Based on these figures, an approximate volume of soils requiring removal is preliminarily
:estimated to be 425 cubic yards. This preliminary volume was calculated using the
average-end area method. The impacted area was calculated for two-foot intervals based
hpon the shaded areas on Figures 4-6 through 4-9. This preliminary volume does include
~emoval of overlying clean soils that do not require remediation to access the soils to be
remediated. It does not include additional excavation for geotechnical stability, etc.
/The preliminary estimate of impacted soil volume has been refined and an estimated
txcavation plan for soil excavation developed for design planning purposes using
geostatistical methods. The excavation plan is presented on Figure 4-10, and the
/geostatistical methods are summarized below. Soil handling procedures that allow for
1overburden soils with penta concentrations below the remedial action goals to be
!stockpiled and backfilled after removal of soils with penta concentrations above the
remedial action goals are discussed below.
4.2.1 Geostatistical Analysis
A geostatistical analysis was used to provide an estimated volume and excavation plan
for the removal of soils having penta concentrations above the remedial action goal. This

analvsis utilized the existing laboratorv and field screening data to estimate soil
c<ln;entrations of penta at !~cations w~ere no data existed~ A description of the
gjostatistical analysis and results are presented in Appendix D.
The results of the g'eostatistical analysis approximated the preliminary soil volume
edtimates and confirmed that a relatively small soil volume appears to be impacted.
I 4.2.2 Soil Remedv Strategv
Bbcause of the smali actual v;lume of soil to be remediated. vendor estimates on unit
phces for on-site BCD tre:1trnent of soil are actually several times higher than reported in
t!le PRC Environmental "Preliminary Data Summary Report". The design strategy is to
elcavate, field screen, segregate, characterize and stage soils. Upon completing this
1ork, pos~-excavation sampling will verify that remedial action goals have been met and
ilie impacted soils have been properly staged on site for treatment.
I Bid packages will be prepared, bids solicited and evaluated for a separate contract for soil
rJmediation. Soil treatment contractor proposals will be evaluated using estimated
v6lumes of materials and a soil treatment contractor will be selected prior to the start of
sbil excavation. After impacted soils are staged Beazer will know the volume of soils to
8e remediated. The soil treatment contractor will mobilize and setup treatment
el~uipment during the excavation of impacted soils.
4.3 EXCAVATION PL~'<
I The excavation plan will remove soils in the former Cellon process and lagoon areas that,
~ased on the predesign investigation, exceed the site-specific cleanup criteria. In general,
the procedures to be followed, as detailed on Figure 7-2, are:
• Excavate an initial soil volume based upon the soil excavation plan
depicted on Construction Drawing No. 4 in Appendix B;
• Segregate and stage soil that, based upon existing data, is not
impacted;
• Conduct post-excavation field screening at the 24 mg/kg and 95 mg/kg
levels;
I

I
I

• Continue removing and staging all soil which exceeds the 24 mg/kg
screening level: soils which exceed 95 mg/kg will be treated: and soils
with screening results berween 24 and 95 mg/kg will be staged
separately;
• Further evaluate by sampling staged soils that field screening indicates
are berween 24 and 95 mg/kg;
• Provide for confirmation by post-excavation sampling (both by
screening and laboratory analysis) to verify attainment of ROD
objectives for soils; and
• Provide for additional removal of soils, if necessary, based upon the
post-excavation screening and sampling.
Backfilling will commence after verification of attainment of the performance standards
hired in Section 7.4.
I
Based on existing laboratory analytical and field screening data, some material within the
~xcavation limits is known to be below the cleanup criteria. This material is estimated to
pe approximately 200 cubic yards and will be staged separately from impacted soils.
Random field screening will be used to help segregate these materials.
I Soils that are known or suspected to be impacted based upon existing data will be staged
~eparately for treatment. This material is estimated to be approximately 425 cubic yards.
!Segregated soils will be staged on site until the BCD treatment process is set up and
,leady for full-scale treatment operations. Excavated material will be temporarily staged
!in bermed areas lined with a 10 mil reinforced polyethylene liner. The liner will be
!covered with a protective layer of soil to prevent damage to the liner. The staged soil will
also be covered with 6 mil reinforced polyethylene sheeting to protect the soil from
weather and to inhibit direct contact with soils. See Figure 4-10 for staging area
schematic. It is not anticipated that the staged soil will be stored longer than 90 days.

4.4 PLANS AND SPECIFICATIONS
I
G:onstruction drawings (90 percent) have been developed and are included as Appendix B
df this submittal. These drawings are intended to present the overall concepts of the
rbmediation. These drawings will be revised as needed during the final phase of the
1
-
design: Figures 4-6 through 4-9 were used to develop the excavation plan and
sbecifications for the soil removal.
I A final site plan for ihe soil remediation is not required. The excavation areas will be
r~graded after backfilling to approximate the current topography and to dovetail with Fire
~ond backfilling. Drawings are included in both full-size and reduced formats for
document completeness and ease of review. Full-size drawings are included as a rolled
s
1
~t, separate from this report.
Appendix C presents the draft specifications anticipated to be used for construction. The
sbecifications were prepared using the Construction Specification Institute (CSI) format
td will be revised as needed during the final stage of design.
4.5 PERMITS
I ~errnits are not anticipated to be required for the excavation and backfilling portion of the
soil remediation work, since all work is on site and the aggregate excavations are
a!nticipated to be less than one acre in size. An erosion and sediment control plan will be
r~quired to meet the substantive requirements of the North Carolina General Construction
I
.
~errnit. Available information from the BCD soil treatment SITE demonstration will be
Provided to the State of North Carolina. Air Qualitv Section for review of air monitoring
I . . -
requirements. Beazer assumes that evaluations conducted as part of the SITE
I
demonstration with regard to ARAR.s, air emission limits, treatment demonstration, etc.,
,,kll be considered applicable to remedial construction, given that the treatment process
II d operating conditions will be the same.
6 ACCESS ISSUES I
.
The soil remediation will require excavation, staging, parking, on-site soil treatment, and
Jpace for truck traffic and temporary facilities. Currently, there is limited space available
.I the soil remediation areas; however, there appears to be sufficient area for on-site BCD

oil treatment. Soil remediation activities will be taking place in close proximitv to the
I
-.
Vnit Strucrures. Inc. property. Care will be exercised to not traverse their property nor
impede their business operations. Strict limits will be observed with respect to site
I oundaries such that impact to the Unit Strucrures, Inc. operations is minimized.
