Preliminary Design Report for Groundwater Interim Remedy
1.0 Introduction
Revision 0
September 7, 2005
The United States Environmental Protection Agency (EPA), under the authority of the
Comprehensive Environmental Response, Compensation and Liability Act of 1980
(CERCLA), as amended by the Superfund Amendments and Reauthorization Act of 1986
(SARA), has initiated procedures to conduct a Remedial Design (RD) at the Ram-Leather
Care Site, located in Charlotte, Mecklenburg County, North Carolina (Figure 1-1). This
Preliminary Design Report for the interim groundwater remedy has been prepared by
Black & Veatch Special Projects Corp. (Black & Veatch) under Contract Number 68-W-
99-043 with EPA Region 4 and under specific authorization of EPA Region 4 through the
Statement of Work (SOW) for Work Assignment Number 369-RDRD-A419 (EPA,
2004a), and in accordance with the· Draft Remedial Design Work Plan for the Ram
Leather Care Site, dated December 6, 2004 (Black & Veatch, 2004). The Draft Remedial
Design Work Plan for the Ram Leather Care Site was approved by EPA on February 24,
2005.
1.1 Purpose and Scope
In accordance with the Remedial Design Work Plan and the SOW, Black & Veatch
presents this Preliminary Design Report (Report) for the interim groundwater remedy to
be performed at the Ram Leather Care Site (Site). This Report begins with the initial
design and ends with completion of approximately 30 percent of the conceptual design
effort. The interim groundwater emedy selected in the Interim Record of Decision
(!ROD) for the Ram Leather Care Site includes pump and treat with physical/chemical
treatment and groundwater monitoring (EPA, 2004b). The preparation of this
Preliminary Design Report will address the interim groundwater remedy and will include
the following:
Design Criteria Report
• Basis of Design Report, including a Summary and Detailed Justifications of
Assumptions.

2.0 Site Conditions
2.1 Site Location and Description
Revision 0
September 7, 2005
The Ram Leather Care Site is located at 15100 Albemarle Road (Route 24/27) in a rural
area of eastern Mecklenburg County, North Carolina, just west of the Cabarrus County
line. The site is located at 35° 13' 41" North Latitude and 80° 36' 24.50" West
Longitude. The site is located approximately four miles west of the Charlotte city
boundary.
Ram Leather Care restored leather goods and operated as a dry cleaning facility.
Chlorinated hydrocarbon chemicals [primarily tetrachloroethylene (PCE) and petroleum
hydrocarbons (mineral spirits)] were used in the cleaning process. The dry cleaning
facility is no longer in operation. The site later operated as a weekend flea market;
however, it is now closed to the public.
A site vicinity map and a site layout map are presented as Figures 1-1 and 2-1,
respectively. The site is presently zoned residential and is surrounded by residential
property. To the south is a 14-acre privately owned parcel. A small fishing pond is
located on the 14-acre parcel. There is a slight gradient sloping from the site to the pond.
To the east is an 8-acre privately owned parcel. To the north is another privately owned
parcel. To the west is an 18-acre privately owned parcel. Albemarle Road and the
Norfolk Southern Railroad are located north of the site. A gravel road running southeast
from the Ram Leather driveway provides access to two residences and the small pond. A
septic tank drain field is located in the southern portion of the site. A former drinking
water well (DW00l l) is located in the northwest portion of the site.
The !ROD for Ram Leather Care describes several source categories; areas identified
were the septic tank/septic tank drain field, former dumpster area, surface water
ditch/culvert, and former drum storage area.
Septic Tank/Septic Tank Drain Field -A subsurface septic tank wastewater system has
been in operation at the site since 1977. The septic tank is located on the north side of the
Ram Leather Care building. Wastewater from the septic tank was pumped to a drain field

in the southern portion of the property. This partially vegetated area is unfenced and
accessible to the adjacent residents.
Former Dumpster Area -The former dumpster area (where filter burning occurred) is
located on the south side of the Ram Leather Care building. This area is currently covered
and serves as part of the gravel parking lot. The wastes generated at the site were placed
in the metal dumpster from 1977 until 1984. The dumpster has since been removed.
Surface Water/Ditch Culvert -Rain water from the northern portion of the site flows
offsite in a northerly direction in a ditch and through culverts under a railroad track and
Route 24/27 to an intermittent stream across the street from the site. Soil samples were
collected from ditch locations just prior to entering the culvert under the railroad track.
The area was sampled to determine if contamination is leaving the site via surface water
drainage. Results indicate that contamination is not leaving the site via surface water
drainage.
Former Drum Storage Area -After 1984, 55-gallon drums were used to store the waste
generated at the site. The former drum storage area is located next to the western part of
the building where drums were placed on a cement pad. A grassy area is adjacent to the
cement pad. Contamination in this area is likely due, in part, to drum leakage and spills.
When discovered in 1991, it was noted that the bungs had been left open allowing rain to
enter the drums and overflow. Areas of stained or stressed vegetation have been observed
in the area adjacent to the drum storage area.
During the April 1999 investigation, a hole was uncovered adjacent to the drum pad. The
hole had been drilled and was approximately 10 inches in diameter. The hole had been
drilled to a depth iri excess of IO feet and is currently filled with collapsed material to a
depth of 10 feet. The drilled hole was covered by a 55-gallon drum lid and cement. Air
monitoring conducted by EPA at the top of the hole indicated the presence of organic
compounds. It is not known whether the hole was the result of a failed well installation
attempt, past sampling activities, or was used for past dumping of solvents. The hole
would have received storm water runoff from the drum storage area.

2.2 Site History
Revision 0
September 7, 2005
The majority of the operational history information presented below was obtained from
the Remedial Investigation Report, Phase I, dated March 14, 2000, and prepared by EPA
Region 4 Science and Ecosystem Support Division (SESD) (EPA, 2000). Additional
information was obtained from the Ram Leather Care IROD (EPA, 2004b ).
The Ram Leather Care facility operated from 1977 to 1993. The building was
constructed in 1967 and housed a constru;tion business owned by Mr. Worley until 1977.
On May 6, 1987, Ram Leather submitted its first Notification of Hazardous Waste
Activity. Ram Leather reported that it was a generator of less than 1,000 kilograms
(kg)/month of D00 I RCRA wastes ( as defined in the Resource Conservation and
Recovery Act [RCRA], 40 CFR 261.21). On June 8, 1987, EPA assigned the number
NCO 982 096 653 to Ram Leather as a small quantity generator.
On April 6, 1991, during a complaint investigation of a demolition landfill on adjacent
property, Mecklenburg County Department of Environmental Protection (MCDEP)
inspector discovered illegal open burning at the Ram Leather Care Site. The facility
operator was burning filters containing PCE. The facility was instructed to stop and
complied. MCDEP issued a Notice of Violation (NOV) for this burning.
On April 29, 199 I, the North Carolina Department of Environment and Natural
Resources (NCDENR) inspector visited the site. The inspector noted that the last
documented disposal of DOOi \\llste petroleum naphtha was on February 12, 1988. Mr.
Worley stated that the Dry Cleaners Trade Association had sent information that certain
petroleum-based dry cleaning solvents were no longer deemed hazardous waste and that
he had assumed that his waste was no longer hazardous. The inspector discovered a 250-
gallon above-ground storage tank of DOOi waste mineral spirits and 49 drums of liquid
waste in an outside waste storage area. Bungs were open, allowing rainwater to enter the
drums and waste to overflow. Logs and drum markings were not maintained. The drums
were standing in liquid. A composite sample of drum contents and a surface soil sample
were taken on May 2, 199 I.
The North Carolina Division of Environmental Management (NCDEM), Water Quality
Section, was notified April 30, 1991, of a boiler blow-off in the storage area. A permit

had not been issued for the site, making this an illegal discharge. The area had been
recently graded to allow surface water runoff to flow toward Albemarle Road. A
drinking water well was noted within 50 feet of the storage area and was sampled on May
6, 1991, by MCDEP. Due to contamination found in the well, Ram Leather was advised
to discontinue using the well for drinking. On May 13, 1991, all off-site drinking water
wells within ½ mile were sampled. Two private residential wells were found to be
contaminated.
On June 5, 1991, a North Carolina Hazardous Waste Inspector visited the Ram Leather
Care Site to provide instructions to Mr. Worley. While there, Ram Leather requested a
change in classification under RCRA because the 49 drums of 0001 hazardous waste
present at the site were in excess of 6,000 kg, thereby exceeding small quantity generator
status. Mr. Worley stated that PCE filters were stored in a dumpster prior to disposal in a
landfill. Stored hazardous wastes were shipped off-site for disposal on June 14,. 1991.
Ram Leather was reclassified as a Large Quantity generator on June 17, 1991.
On June 24, 1991, an Imminent Action NOV (Docket #91-264) was issued to Ram
Leather Care for Storage and Disposal of Hazardous Waste. The compliance schedule
required submittal of a comprehensive sampling and analysis report by July 26, 1991, soil
removal with post-excavation samples by September I, 1991, and remowl of all
hazardous wastes by September 1, 1991.
On July 2, 1991, an NOV was issued by NCDEM Groundwater Section for violation of
groundwater quality standards. The NOV required remediation of contaminated soil and
groundwater and provision of an altema te water supply to affected well owners (Parnell
and Beaver). On July 26, 1991, NCDEM Groundwater Section held in abeyance the
order to remediate the site and deferred lead agency status to the North Carolina
Hazardous Waste Section. The NOV still required provision of alternate water supply to
affected well owners. On August 2, 1991, Ram Leather responded to NCDEM by letter
and said that the two private residences had been provided with bottled water and on
November 5, 1991, Ram Leather submitted a Technical and Field Data Report to
NCDENR.

On January 24, I 992, a Compliance Order with Administrative Penalty, Docket #92-068
was issued by the North Carolina Division of Solid Waste Management (NCDSWM).
This NOV stated that between 1977 and 1984, wastes generated from the use of
chlorinated hydrocarbons were disposed of in a metal dumpster. After 1984, 55-gallon
drums were used to store the solvents which were then transported off-site for recycling.
Between 1984 and I 988, wastes were also stored in an above-ground waste tank
supported by a concrete pad on the west side of the building. The NOV cited Ram
Leather for storage of hazardous waste on-site for longer than 90 days, improper or lack
of marking on hazardous waste containers, failure to file an annual report, discharge of
000 I and F002 hazardous wastes onto the ground and into the groundwater, and failure
to submit a permit application. The NOV imposed a penalty.
On February 26, 1992, Ram Leather filed a petition for an Administrative hearing to
contest the order. On April 29, 1992, NOV Docket #92-232 was issued to Ram Leather
by the NC Hazardous Waste Section for failure to submit an annual report. On May 12,
1992, Ram Leather responded with the annual report and contested the NOV. Ram
Leather stated that generator status was based on amount generated, not stored. The
annual report stated that the following quantities of wastes were generated and shipped
off-site in 1991:
Perchloroethylene/ignitable, 0039 2,900 kg
Filters containing waste perchloroethylene/ignitable, 0039 1,268 kg
Filters containing waste mineral spirits/ignitable, DOOi
Waste mineral spirits/ignitable, 000 I
700 kg
3,315kg
On July 17, 1992, Ram Leather provided a Soil Vapor Extraction Proposal to NCDENR
Attorney General's Office. A memo dated July 29, 1992, from the North Carolina
Hazardous Waste Inspector to the North Carolina Assistant Attorney General, states that
Ram Leather was not in compliance with NOV Docket #91-264. This memo also stated
that Ram Leather had made little attempt to meet the requirements of the order which
required removal of on-site contaminated soil.
On January 30, 1992, Mecklenburg County again sampled area wells. NCDEM
communicated to Mr. Worley on March 16, 1992, that he was still required to provide

alternate water supply to residents with contaminated wells. It was suggested that Mr.
Worley consider a point of entry filter system. On July 15, 1992, Ram Leather sampled
three water supply wells including the new onsite well. An August 10, 1992, letter states
that Ram Leather continues to supply alternate water supplies to both residences. On
August 26, 1992, Mecklenburg County again sampled area wells and determined that an
additional residential well was also contaminated. On March 18, 1993, Ram Leather
filed for Chapter 7 Voluntary Bankruptcy. On April 19, 1993, NCDEM requested that
the Commerce Finance Center pursue funding to provide a permanent alternate water
supply.
Additional well samples taken by Mecklenburg County on June 22, 1993, showed that
the well at 15205 Albemarle Road was contaminated. Subsequent tests have shown the
well to be clean. On September 8, 1993, NCDSWM Waste Management Branch referred
the site to the North Carolina Superfund Section for possible immediate action to provide
a reliable alternative water supply to the residents. A September 28, 1993, inspection
report stated that the Ram Leather facility was in Chapter 7 bankruptcy and had been
unable to comply in full with Compliance Order with Administrative Penalty Docket
#92-068. Alternative water was still being provided to area residents who would accept
it, but site cleanup had not progressed.
On February 16, 1994, the North Carolina Superfund Section requested that EPA
evaluate Ram Leather for a possible removal action and on March 16, 1994, the EPA
sampled on-site soil and neighboring wells. The EPA determined that wells surrounding
the site were below removal action levels and assigned the site a low priority for removal
action.
Between the EPA iemoval evaluation and September 26, 1995, a new deep well was
installed at the residence located across the street from the facility. The resident had
discontinued using bottled water and had resumed drinking the groundwater. The new
well was sampled during the North Carolina Superfund Section Site Inspection on
September 26, 1995. The well showed 204 parts per billion (ppb) of PCP, which was
much higher than any previous sampling results from that residence. The MCDEP also
sampled the well and found a high levei of PCE. The NC Superfund Section again

requested an EPA removal action. The EPA sampled the well and determined that it
qualified for a high priority removal action.
In 1997, EPA's Emergency Response and Removal Branch conducted a follow-up
investigation to verify the findings of the State's 1995 investigation. Private wells in the
vicinity of the site were sampled. The results indicated that the levels of contamination
exceeded the removal action level. Thus, in February 1997, point-of-entry carbon
filtration units were installed on the Parnell, Glosson, and Beaver wells. Each of these
wells has consistently shown chlorinated hydrocarbon contamination.
EPA SESD completed the first phase of the Remedial Investigation (RI) in 1999 to assess
the areal and vertical extent of contaminated soil and groundwater at the site, and to
determine whether additional potable wells adjacent to the site were contaminated. In
2000, EPA tasked COM to undertake additional groundwater studies (Phase II). The
main objectives of the additional studies were to determine the nature of the fracture
zones in the area and the extent of contamination in the fractured bedrock aquifer. A
review of the data collected suggests that the extent of contamination has been defined to
the north and west-northwest of the site, but remains to be defined on the southern side
and the east-northeast directions from the facility. Additionally, four private wells
sampled during the 2000 RI sampling event still showed unacceptable levels of
contamination (EPA, 2004b ).
The !ROD for the Ram Leather Care site was issued on September 30, 2004 (EPA,
2004a). The interim remedy selected in the !ROD includes Soil Alternative S3 -
Excavation, Off-Site Transportation, and Disposal at Subtitle D Landfill; and
Groundwater Alternative G3 -Pump and Treat with Physical/Chemical Treatment and
Groundwater Monitoring. The RD for the interim soil remedy was prepared by Black &
Veatch and submitted under separate cover. The selected interim remedy meets the
requirements of the two mandatory threshold criteria: protection of human health and the

treatment; and cost. The selected interim remedy also includes flexibility, to the extent
possible, to allow for future redevelopment of the site.
2.3 Hydrogeologic Setting
The majority of the geologic features of the site presented below were obtained from the
Remedial Investigation Report, Phase I, dated March 14, 2000, and prepared by EPA
Region 4 SESD (EPA, 2000).
2.3.1 Topography and Surface Drainage
The total relief on the site is about 13 feet, ranging from a basin in the northwest comer at
717.2 feet above mean sea level (ams!) to the highest point of 730.4 feet ams! in the
south. There are two overland flow paths for site drainage. The northern pathway flows
through culverts under the railroad tracks and Route 24/27. This intermittent stream
continues for 1,500 feet until it joins a perennial stream. This perennial stream continues
north for 1,000 feet and flows into a pond that is 800 feet long. The outfall from this pond
is an unnamed tributary to Caldwell Creek.
Runoff from the southern portion of the site flows south and enters a pond 1,000 feet to
the south. The porxl is 200 feet long. Several springs emerge along the overland flow
pathway and in other areas between the site and the pond. The outfall from this pond
flows 1,200 feet where it enters a larger pond. Outfall from this pond enters Wiley
Branch which leads to Clear Creek.
2.3.2 Climate
The area has a mean annual 45 inches of precipitation per year and a mean annual lake
evaporation of 41 inches per year, resulting in a net precipitation of 4 inches (U.S. Dept.
of Commerce, 1979). The two-year 24-hour rainfall is 3.5 inches (U.S. Dept. of
Commerce, 1963). The site is outside the 500 year flood plain (Federal Emergency
Management Agency, 1993).
2.3.3 Geology
The soils at the site are classified as part of the Georgeville unit, characterized by a silty
clay loam. The surface layer is a yellowish red silty clay loam, approximately 5 inches
thick. Below this is about 4 feet of strongly acidic subsoil, the upper part of which is a red

silty clay. The lower part is a red silty clay loam. Under the subsoil is silt loam to
approximately 9 feet below land surface (bls). Depth to bedrock is about 42 feet bls
(Tingle, 1991).
The site is located in the western edge of the Carolina Slate Belt of North Carolina.
Classified as phyllites, these rocks are very fine in texture. The metavolcanic rock is
characterized by interbedded felsic to mafic tufts and flowrock. The residuum from the
fine grained slate forms the Georgeville series subsoil mentioned above (U.S. Dept. of
Agriculture, 1980; USGS, 1980).
Rock units in the area have undergone periods of deformation that have produced folding
and fractured planes in the rock, as well as brittle zones where the rock is crushed,
sheared, or faulted in some manner. As these rock types become weathered, soil profiles
develop that are characteristic of the original rock (also referred to as saprolite). The
rocks have been fractured during metamorphic phases and, in some cases, the fractures
have been "resealed" by quartz. As rock weathers, these quartz fillings are retained in the
soil indicating that fractures existed in the rock. In addition, remnant fractures can be
seen in the soil profile without quartz infilling as indicated by the presence of iron
staining along the fracture plane. The iron staining is a result of groundwater leaching
iron from the surrounding material. As groundwater travels along a fracture plane, the
iron is re-deposited along the plane. Fracture planes can be detected during drilling as
zones of weak-to-incompetent rock that are not resistant to the cutting action of the drill
bit. These fracture zones are typically water saturated.
Stratigraphy at the site consists of a saprolite layer, a partially weathered rock zone, and
the underlying fractured crystalline bedrock. The saprolite is clay-rich, residual material
derived from in-place weathering of bedrock. Typically, the saprolite is silty clay near the
surface. With increasing depth, the amount of silt, and fine-grained sand and gravel tend
to increase. Remnant fracture planes with quartz infilling appear in this layer.. The
thickness of the saprolite in the vicinity of the site ranges from 24 to 42 feet. The range is
based on soil borings drilled in 1991 that showed auger refusal at 24 feet and the well log
for the onsite deep well that showed the depth to bedrock as approximately 42 feet bls.
This is consistent with the August 1999 drilling in which bedrock was encountered at
approximately 45 feet bls.

Underlying the saprolite is a partially weathered rock layer derived from the weathering
of bedrock. Partially weathered rock is composed of saprolite and fragments of weathered
bedrock. Grain sizes range from silts and clays to large boulders of unweathered bedrock.
The weathering occurs in bedrock zones less resistant to physical and chemical
degradation (i.e., fault zones, stress relief fractures, and mineralogic zones).
2.3.4 Hydrogeology
Regionally, the water-bearing units that underlie the site represent an aquifer system
consisting of metamorphosed and fractured phyllite rocks of varying proportions and
thicknesses. The aquifer system underlying the site generally consists of the
saprolite/partially-weathered rock aquifer and the underlying fractured bedrock aquifer.
In the site area, the water is typically found in the saprolite aquifer and will generally
mimic the overlying land surface. Based on measurements collected during aquifer
testing, the depth to water is approximately 15 feet.
Shallow groundwater movement is assumed to somewhat follow the topography. Based
on a U.S. Geological Survey (USGS) topographic map, ground surface at the site slopes
to the southeast and the northwest, creating a groundwater divide. However, groundwater
flow is likely controlled by the presence of relict fractures present in the saprolite,
fractures in the partially-weathered as well as competent bedrock, and the steep dip of the
bedrock units to the northwest. Given the complexity of the bedrock at the sit~, the
direction of groundwater flow depends primarily on fractures, faults, bedding planes, etc.
2.4 Groundwater Characterization and Extent of Contamination
This section presents the results of groundwater investigation activities performed in
1999 and 2000 as part of the Remedial Investigation; Phase I, conducted by EPA Region
4 SESD (EPA, 2000) and Phase II conducted by CDM Federal (CDM, 2001).
Groundwater sampling locations and volatile organic compound (VOC) results are
presented on Figure 2-2.

this investigation are presented in the Remedial Investigation Report, Phase I (EPA,
2000).
2.4.1.1 Shallow Monitoring Wells. During the 1999 investigation, the tlree on-site
shallow groundwater monitoring wells IMW00l 1 (MW! -total depth 32 feet bis),
MW0022 (MW2 -total depth 32 feet bis), and MW0033 (MW3 -total depth 20 feet
bis)] were sampled for VOCs. VOCs were not detected in any of the on-site shallow
wells.
2.4.1.2 Deep Monitoring Well. The on-site deep monitoring well (DW00 I I) (510 feet
deep) was sampled for VOCs, base neutral acids (BNAs), pesticides, and metals during
the April 1999 investigation. Trichloroethene (TCE) [210 micrograms per liter (ug/L)],
PCE (4,000 ug/L), cis-1,2-dichloroethene (1,200 ug/L), and fourteen metals were
detected in DW00l 1. The April 1999 metals sample was contaminated with mercury by
the Contract Laboratory Program (CLP) laboratory. Due to this contamination, the deep
well was re-sampled in June 1999 for metals. Analysis of the June 1999 sample resulted
in no detectable mercury concentrations.
2.4.1.3 Residential Potable Wells. During the 1999 investigation, ten residential wells
near the site were sampled for VOCs, BNAs, pesticides, and metals. Pre-and post-
carbon filter samples were collected from the residences with filtration systems and
known groundwater contamination (PW00I I, PW0022, and PW0l 13). Chlorinated
solvents were detected in the pre-carbon filter samples collected at the three residences
known to have contaminated wells. Levels of PCE in all three pre-filter samples and
TCE in one sample (PW0 113) exceeded applicable maximum contaminant levels
(MCLs). PCE and cis-1,2-dichlorobenzene were detected in one sample (PW00312)
collected from a residence without a carbon filter system. The April 1999 potable water
metals samples were contaminated with mercury by the CLP laboratory. Due to this
contamination, the wells were re-sampled in June 1999 for metals. Analysis of the J,une
1999 samples resulted in no detectable mercury concentrations. However, antimony was
detected at two residences in June 1999; the MCL of 6 ug/L was exceeded (30 ug/L) at
one residence (PW00 11 ). Because of the presence of antimony, additional metals
samples were collected at _the two residences in August 1999. No detectable
concentrations of antimony were found at either residence. Antimony was detected

above the MCL at another residence (PW0022) during t_he April 1999 investigation;
however, antimony was not detected at this residence in June 1999.
2.4.2 Phase II 2000 Investigation
The second phase of the groundwater investigation was conducted in 2000 by CDM
Federal The purpose of this investigation was to determine the extent of contamination
in the fractured bedrock aquifer. Results of this investigation are presented in the Final
Groundwater Investigation Report (CDM, 200 l ). The 2000 investigation included the
following:
• Installation of soil borings to estimate the depth to the top of bedrock.
• Installation of four borings to depths of 182 ft bls (B-1 / MW-ID), 42 ft bis (B-2 /
MW-2D), 183.5 ft bls (B-3 / MW-3D), and 182 ft bls (B-4 / MW-4D).
• Collection of groundwater samples for VOC analyses from water producing
fracture zones within each of the four borings.
• Installation and development of four groundwater monitoring wells, one in each
of the four borings. Monitoring well screens were set based upon VOC results
from fracture zone analyses.
• Collection of groundwater S11Uples for VOCs, semi-volatile orgaruc compounds
(SVOCs), and target analyte list (TAL) Metals from each of the four monitoring
wells.
Through the evaluation of rock cores obtained from boring B-1, contamination migration
pathways were assessed. The diagonal fracture pattern of the cores suggests that
migration pathways exist for contarrunants to migrate downward into the subsurface.
VOC analyses resulted in compound detections but no MCL exceedances. The following
is a summary of the VOCs detected:
• MW-ID -Chloroform
• MW-2D -PCE, cis-1,2-DCE, 1,2-DCA, carbon disulfide, and acetone
• MW-3D -Acetone, 1,2-DCA, and chloroform
• MW-4D -1,2-DCA and carbon disulfide

SVOCs were analyzed for, but no compounds were detected. Pesticides analyses resulted
in detectable concentrations of pesticides, below MCLs, in all four wells. The following
is a summary of the pesticides detected:
• MW-ID-4,4'-DDT, alpha-chlordane, delta-BHC, endosulfan I, endrin aldehyde,
and gamma-chlordane
• MW-2D (Duplicate) -Gamma-chlordane
• MW-3D -4,4'-DDD, alpha-chlordane, endosulfan sulfate, and endrin aldehyde
• MW-4D -Endosulfan I
Several inorganic arnlytes were detected below then-prevailing MCLs in each well. The
following is a summary of the metals detected:
• MW-ID -Aluminum, arsenic, barium, calcium, chromium, copper, iron,
magnesium, manganese, nickel, potassium, sodium, mercury, and zinc.
• MW-2D -Aluminum, barium, calcium, chromium, cobalt, copper, iron, lead,
magnesium, manganese, potassium, sodium, and zinc.
• MW-3D -Aluminum, arsenic, barium, calcium, chromium, copper, iron, lead,
magnesium, manganese, potassium, sodium, and zinc.
• MW-4D -Barium, calcium, chromium, copper, lead, magnesium, manganese,
potassium, sodium, and zinc.
Based on the results of the Phase II groundwater investigation, the extent of
contamination has been adequately defined to the north and west-northwest of the site. It
was concluded by CDM Federal that the extent remains to be defined to the south and the
east-northeast of the facility.
The data collected during the 1999 EPA RI and 2000 groundwater investigation suggest
that groundwater at neighboring private wells are contaminated with chlorinated solvents
typically associated with dry cleaning operations. Concentrations of chemicals of
concern in area wells are presented on Figure 2-2. Data indicate that metals, SVOCs, and
pesticides are not of concern at the site. Groundwater contamination will be addressed in
this preliminary design report; whereas, soil contamination was addressed under separate
cover. As proposed in the !ROD and more fully detailed in the Focused Feasibility Study
Report (CDM, 2004), the ultimate site goal is to restore the groundwater aquifer system
by cleanup to the risk-based remedial goal objectives (RGOs) and/or ARARs [remedial

action objectives (RAOs)] presented in Table 2-1. Analytes in the following wells have
at one time exceeded RAOs: old onsite well, new onsite well DW00l l, Parnell well
PW00l l, Beaver well PW022, Glosson well PW0l 13, Tucker well PW0089, Ivey well
PW00312, MW-ID, MW-2D, MW-3D, and MW-4D. The primary immediate objectives
of the interim action are to reduce site risks by preventing exposure to contaminated
groundwater and further migration of contaminants, and to provide additional site data to
assess restoration potential. Specifically, the alternative selected to meet the objectives
includes pumping groundwater from an existing on-site well to an on-site treatment
system, and continued monitoring of site groundwater and nearby private wells.

Preliminary Design Report for Groundwater Interim Remedy
3.0 Project Description
Revision 0
September 7, 2005
On-site contaminated soil is an ongoing source for groundwater contamination.
Contaminated soils were previously addressed in the Preliminary Design Report for Soil
Interim Remedy (Black & Veatch, 2005a) submitted under !Eparate cover. After the
removal of on-site contaminated soils to 26 feet bis, the source for groundwater
contamination should be significantly reduced. The Focused feasibility Study (FFS)
addresses the reduction of the contaminant plume migration in groundwater, and remedial
alternatives for the contaminated groundwater plume identified during the RI were
presented in the FFS.
Contamination in onsite deep well DW00l l will be addressed as part of the groundwater
interim RA. The objective of the groundwater interim RA is to I) reduce contaminant
plume migratiof\ 2) prevent exposure to contaminated groundwater, 3) reduce migration
or contaminants from sources, and 4) provide additional site data to assess restoration
potential for the full RA. This interim RA is short-term in nature and is not designed to
fully remediate all groundwater contamination associated with the Ram Leather Care site.
Ultimately, the RAOs for the site may include the following:
• Prevent ingestion of groundwater having concentrations greater than remediation
goals;
• Restore the groundwater aquifer system by cleanup to the remediation goals, and
prevent the migration of the pollutants beyond the existing limits of the known
contaminant plume or established point of compliance; and
• Control future releases of COCs · in groundwater to ensure protection of human
health and the environment.
The selected interim remedy for groundwater specifically provides for the following:
• Constructiof\ optimization, and operation of an interim pump and treat systefl\
for a duration of five years, to remove contaminated groundwater from onsite
deep well DW00! I.
• Weekly operation and maintenance (O&M) system inspections, corrections, and
parts replacement as necessary.

• System performance monitoring of groundwater entering the treatment system
and at selected points in the treatment train (total of 5 samples assumed) to ensure
proper contaminant removal efficiencies. voes and T AL metals will be
monitored monthly.
• Routine monitoring of groundwater exiting the treatment system to ensure
adherence to National Pollution Discharge Elimination. System (NPDES)
permitting requirements. Monitoring frequency and parameters will be specified
in the discharge permit. For cost estimation, monthly monitoring of voes, TAL
metals, and TSS, and quarterly chronic toxicity testing are assumed.
• Baseline and cparterly monitoring of all site wells and residential wells in the
surrounding area for voes for a period of five years.

4.0 Design Criteria
4.1 Introduction
Revision 0
September 7, 2005
The Design Criteria defines in detail the technical parameters upon which the design will
be based. Specifically, the Design Criteria shall include the preliminary design
assumptions and parameters, which may include (I) waste characterization; (2)
pretreating requirements; (3) volume and types of each medium requiring treatment; (4)
treatment schemes (including all media and byproducts), rates, and required qualities of
waste streams (i.e., input and output rates, influent and effluent qualities, potential air
emissions, and so forth); (5) performance standards; (6) long-term performance
monitoring and O&M requirements; (7) compliance with all ARARs, pertinent codes,
and standards; (8) technical factors of importance to the design and construction
including use of currently accepted environmental control measures, constructability of
the design, and use of currently acceptable construction practices and techniques. The
interim groundwater RA for this site consists of groundwater pump and treat from onsite
deep well DW00l l with physical/chemical treatment prior to discharge to surface water.
The remedy involves construction, optimization, and O&M of a pump and treat system,
treatment efficiency monitoring, and routine sampling of area monitoring wells and
residentia I wells. The following sections outline design criteria for major components of
the groundwater interim RA.
4.2 Groundwater Cleanup Standards
Section 8 of the !ROD for the RAM Leather Care site, dated September 2004, establishes
the RAOs for groundwater. Groundwater from the most contaminated onsite well,
DW00I I, will be extracted, treated onsite, and discharged to surface water. The interim
RA is not intended to remediate groundwater to established standards, but instead protect
human health and the environment by preventing exposure to contaminated groundwater
and reducing migration of the contaminant plume.
4.3 Groundwater Remediation Design Criteria
All activities associated with the interim groundwater RA will be performed under a
performance work statement by a qualified groundwater remediation subcontractor. EPA
guidance for the design and construction of pump and treat systems shall be in
4-1
EPA Contract No. 68-W-99-043

accordance with, but is not limited to, the Design Guidelines for Conventional Pump-
and-Treat Systems (EPA, 1997) and the Cost-Effective Design of Pump and Treat
Systems (EPA, 2005).
4.3.J Pump and Treat System Construction
A pump and treat system will be designed and constructed by a qualified remediation·
subcontractor. Appropriate treatment system construction permits will be obtained by
Black & Veatch The system will be designed to pump groundwater contaminated with
VOCs from onsite deep well DW00I I, treat the contaminated groundwater, and
discharge treated water to surface water per NPDES permit requirements. The objective
of the pump and treat system is to reduce contaminant plume migration; therefore,
groundwater will be pumped from DW00I I at the highest sustainable rate. Based on
results of aquifer testing conducted in June 2005, well DW00 11 is capable of sustaining a
pumping rate of 6.5 -7.0 gallons per minute (gpm) (Black & Veatch, 2005b ). A higher
rate may be achieved during periods of high rainfall; therefore, a down-well pump
capable of sustaining a flowrate of at least 10.0 gpm will be utilized (for cost estimation
purposes, equipment will be sized for 12 gpm). The pump will be fixed with controls,
such as a float switch, to prevent the pump from operating if the water level drops below
the intake to prevent damage to tre pump. The pump will be set at 270 feet bis,
corresponding to the depth at which the highest level PCE of contamination was observed
during p:tcker testing conducted in 2000 an_d the depth at which aquifer testing was
conducted. A pressure transducer will be installed to measure water level fluctuations in
the extraction well. After installation of the down-well pump, pressure transducer, and
system piping, the well will be sealed to prevent rain or other objects from entering the
well.
The required basic treatment system components are discussed herein. A sample
treatment system layout is presented as Figure 4-1. The system will include meters for
measuring flow rate and total volume of extracted water, and mechanical run timers for
the groundwater extraction pump, transfer pumps, and air stripper blower. Sample ports
will also be installed for routine treatment efficiency sampling required by the NPDES
permit. In order to meet discharge requirements set forth in the NPDES permit, it is
likely that primary, secondary, and possibly tertiary water treatment will be necessary.
Pre-filtration will also be included to remove potential sediments and large particles. The

system will be capable of pumping treated water through the system to the pond located
approximately 1,000 to 1,500 feet southeast oftlie site. For cost estimation purposes, the
cost of two transfer pumps will be included; one for pumping water through the treatment
train and one for pumping treated water to the pond. Controls should be present to
prevent accilental discharge of groundwater to the ground or back into the well.
Installation of a telemetry system for remote system monitoring is desirable to spot-check
operations and to accurately calculate contaminant removal rates and volumes. In
addition, telemetry will allow the subcontractor to respond promptly to system failures.
Power transmission lines, exist on-site and currently supply .electricity to the Ram Leather
Care building. It is unlikely that the existing power supply will be sufficient for
groundwater remediation activities; therefore, the subcontractor is responsible for
obtaining the services of the power company and/or a qualified electrician to ensure
system demands are adequately and safely met.
During aquifer testing it was determined that, in addition to primary treatment via air
stripping, secondary treatment in the system, at a minimum, is necessary to guarantee that
treated groundwater meets discharge standards to be mandated by the NPDES permit.
Post-treatment samples collected during the aquifer test indicate that concentrations of
VOCs and arsenic in the treated groundwater were too high to discharge and require
additional treatment. Aquifer test analytical results are reported on Table 4-1. Analytical
results are compared to North Carolina Department of Environment and Natural
Resources (NCDENR) 2L Standards (NCDENR, 2005) [also the ARARs (fable 2-1)
presented in the !ROD], Federal MCLs (EPA, 2002), and National Recommended Water
Quality Criteria for Human Health for Priority Toxic Pollutants (EPA, 2004c).
Maximum concentrations detected in the influent during aquifer testing are compared to
assumed discharge criteria in Table 4-2. Since final treatment system discharge standards ' will not be known until the NPDES permit is issued, for the purposes of this document
the North Carolina 15A North Carolina Administrative Code (NCAC) 2B Fresh Surface
Water Quality Standards for Class C Waters (NCDENR, 2003) are assumed as discharge
limits. In the absence of an established North Carolina Fresh Surface Water Quality
Standard, the 1999 EPA National Recommended Water Quality Criteria for Human
Health for Priority Toxic Pollutants for consumption of organism only will be assumed.
The NCAC 2B standards are aligned with the 1999 EPA National Recommended Water

Quality Criteria based on a fish consumption rate of 6.5 grams per day. However, the
EPA National Recommended Water Quality Criteria were revised in 2004 to reflect a fish
consumption rate of 17.5 grams per day, resulting in more stri:t criteria_. North Carolina
is conducting a triennial review in 2006 to re-align the NCAC 2B standards with the 2004
EPA National Recommended Water Quality Criteria. For comparison, both the 1999 and
2004 EPA National Recommended Water Quality Criteria a-e presented in Table 42.
The following constituents or water quality parameters exceeded assumed discharge
criteria: PCE, TCE, aluminum, arsenic, copper, iron, zinc, and turbidity.
The secondary and tertiary (if necessary) treatment specified in the design should be
capable of removing remaining VOCs, arsenic, copper, iron, zinc, and turbidity to levels
specified in the NPDES permit, yet to be obtained. Air strippers and granular activated
carbon (GAC) filters have been shown to remove chlorinated VOCs. Activated alumina
filters, anion exchange, distillation, reverse osmosis, nanofiltration, iron oxide filters, and
GAC filters (to some extent) are treatment methods proven to remove arsenic and other
metals. Turbidity will likely be reduced to acceptable levels through pre-filtration and
GAC filtration. Submittal of the NPDES permit application is scheduled after receipt of
analytical results after conducting secondary treatment of the groundwater extracted
during the 2005 aquifer test. The NPDES permit approval process may take more than 6
months. For cost estimation purposes, the treatment system will include an air stripper
(primary treatment for VOCs), a GAC unit (secondary treatment for VOCs and some
arsenic), and an activated alumina filter (tertiary treatment for arsenic). System design
modifications may be necessary to meet limits mandated by the NPDES permit.
4.3.2 System Optimization
An initial period of system optimization will be conducted to ensure proper system
extraction rates and adequate contaminant removal efficiencies prior to discharge.
4.3.3 System Operation and Maintenance
System O&M activities will initially be conducted on a weekly basis to prevent
equipment failure or decline with tre goal of maximizing efficiency and reliability.
System parameters such as flow rate and total groundwater volume will be recorded.
Water level in the extraction well will be recorded by pressure transducer throughout the
duration of system operation. Other important system observations such as fouling,

leaking, clogs, improperly operating equipment, etc. will also be noted. If so determined
by EPA, O&M activities may be conducted less frequently.
4.3.4 Groundwater Discharge
The treatment system will be capable of pumping treated water through the system to the
pond located approximately 1,000 to 1,500 feet southeast of the site. The treatment
system discharge line will be installed underground for protection, to maintain the
integrity of the line. For cost estimation purposes, a trench 2 feet deep and I foot wide
and polyvinyl chloride (PVC) discharge piping were specified. All underground utilities
should be located prior to any digging or trenching. The discharge point will be located
on the northern side of the pond, unless otherwise specified by the NPDES permit, and
measures to minimize erosion will be implemented.
4.3.5 Groundwater Monitoring
Baseline and quarterly monitoring of all onsite wells [DW00ll, MW00II (MW!),
MW0022 (MW2), MW0033 (MW3), and MW2D] and wells in the surrounding area
(Segrest PW00ll, Glosson PW0I 13, Ivey PW00312, Beawr PW0022, Tucker PW0089,
MWID, MW3D, and MW4D) for VOCs will be conducted throughout the duration of the
interim groundwater RA ( 5 years). Monitoring reports will be submitted as specified in
Section 4.5. In addition to quarterly monitoring, treatment system effluent monitoring
and reporting will also be required as specified by the NPDES permit.
4.3.6 Site Access and Safety
Security measures, such as permanent fencing, shall be incorporated to prevent
unauthorized entry into the treatment system area. In addition, signage will be posted to
deter trespassing.
4.4 Air Monitoring
Air monitoring equipment will be utilized during system start-up to ensure personnel
safety. However, routine air monitoring will not be required and no air discharge permit
1s necessary.

4.5 Land Acquisition and Easement Requirements
Revision 0
September 7, 2005
No land acquisition or easement access will be required because all groundwater interim
RA activities are to be conducted on land belonging to Mr. Worley, the site owner.
Access to adjacent properties not owned by the site owner will be required for quarterly
groundwater monitoring.
4.6 Quality Assurance/Quality Control
Design quality assurance/quality control (QA/QC) will be critical to tbe successful
completion of the groundwater interim remedy. The work assignment QC measures for
the remedial design are described in the Remedial Design Work Plan dated December 6,
2004 (Black & Veatch, 2004). The major project deliverables defined in the work plan
and SOW that will be subject to the work assignment quality control measures are listed

• Transportati?n and disposal bills of lading, weigb tickets, and manifests for
waste materials
• Equipment and personnel decontamination procedures and methods
• Air monitoring procedures and general health and safety
• Overall documentation of RA activities
4.7 Site Restoration
Plans and specifications will require that the site be maintained in a neat and crderly
fashion throughout construction activities. All construction disturbances will be restored
to pre-construction conditions to prevent safety hazards, erosion, and impacts to property
owners. Upon completion of the interim groundwater RA, EPA will specify what should
be done with the treatirent system equipment. It is likely that the treatment system will
remain onsite for the full RA.
4.8 Reporting
Quarterly progress reports shall be prepared to summarize groundwater monitoring and
remediation progress and any issues encountered with the treatment system. Periods of
downtime should be discussed in detail. The first quarterly report should discuss system
installation and include a summary of system specifications, installation activities, and
sys tern optimization. Subsequent quarterly reports will include extracted water volumes,
flow rates, run times, groundwater levels, contaminant trends, etc. The final quarterly
report, to be completed after a period of 5 years, unless directed otherwise by EPA,
should include a summary of contaminant trends and discuss site status. In addition,
reporting required by applicable permits such as NPDES shall be performed.

September 7, 2005
The Basis of Design presents a detailed description of the evaluations conducted to select
the design approach, and shall include a Summary and Detailed Justification of
Assumptions. This summary may include (I) calculations supporting the assumptions;
(2) a draft process flow diagram; (3) a detailed evaluation of how all ARARs will be met;
(4) a plan for minimizing environmental and public impacts; and (5) a plan for satisfying
permitting requirements.
5.1 Design Assumptions
During preparation of this design, assumptions have been made regarding sequence of
work; work by others; property access; and fate, transport, and physical properties of the
contaminants of concern as they relate to remediation. A description of each of the
relevant assumptions is presented below, including a justification or supporting
documentation as to the accuracy and acceptability of each assumption.
• Prior to installation of the groundwater pump and treat system, baseline
groundwater sampling will be conducted on 13 wells. All site wells [DW00 11,
MW00l l (MW!), MW0022 (MW2);MW0033 (MW3), and MW2D] and wells in
the vicinity of the site (Segrest PW00ll, Glosson PW0113, Ivey PW00312,
Beaver PW0022, Tucker PW0089, MWID, MW3D, and MW4D), both
monitoring and private, will be sampled for VOCs.
• DNAPL is not present in the groundwater.
• A treatability study will be conducted by the subcontractor to determine design
parameters of treatment components.
• Chronic toxicity testing will be included in the treatability study in anticipation of
NPDES permit requirements.
• A groundwater extraction and treatment system will be installed to extract VOC-
contaminated groundwater from well DW00ll. The system will be capable of
extracting groundwater at a minimum rate of I 0.0 gpm. Extracted groundwater
will require treatment to remove VOCs, turbidity, and metals, including arsenic.
• Estimated pumping rate (6 -10 gpm) and contaminant concentrations requiring
treatment.

• System performance monitoring will be conducted monthly at five locations in
the treatment train (influent and between each treatment). Samples for VOCs and
T AL metals will be collected.
• Discharge and system perfurmance monitoring will be conducted during visits for
weekly system O&M checks.
• Access to adjacent properties will be required for groundwater monitoring
activities.
• No air emissions permit will be required.
5.2 Process Flow Diagrams
Interim remedial activities at the site will generate the following primary waste streams:
contaminated groundwater, spent pre-filters, spent activated carbon, spent activated
alumina, air stripper maintenance. fluids ( acidic waste waters), and treated groundwater.
Figure 5-1 shows a generalized process flow diagram for these waste streams.
Contaminated groundwater will be treated by an onsite system and treated groundwater
will be discharged to a pond located to the soutreast of the site. Effluent will be routinely
monitored by the subcontractor as specified by the NPDES permit to ensure that
groundwater rreets the discharge criteria. If discharge does not meet the standards, the
system will be optimized.
5.3 Operation and Maintenance Provisions
Minimum requirements for O&M activities and reporting by the interim RA
subcontractor shall include weekly system inspections and optimizations and effluent
monitoring as specified by the NPDES permit throughout the duration of the interim RA.
Parts will be repaired or replaced as necessary and filtration units will be replaced prior to
contaminant breakthrough. Equipment maintenance and inspection logs for all system
components will be completed and maintained at the site. Black & Veatch will
immediately be notified of any malfunctions resulting in system downtime for a period of
greater than 24 hours. The RA subcontractor will be required to submit for approval an
O&M Plan providing a schedule and description of activities to monitor and maintain the
integrity of the remedial activities.

5.4 Permitting
Revision 0
September 7, 2005
In accordance with the provisions of CERCLA and SARA Black & Veatch does not
anticipate the need for a formal federal, state, or local permit application and approval
process in order to perform the proposed RA. However, Black & Veatch anticipates the
need for an ATC permit for system construction and a NPDES permit for discharge of
treated groundwater.

6.0 Project Delivery Strategy
Revision 0
September 7, 2005
As described in the Remedial Design Work Plan dated December 6, 2004 (Black &
Veatch, 2004), documents related to the groundwater interim RA include:
• Preliminary Design Report for Groundwater Interim Remedy (including: Basis of
Design Report, Design Criteria Report, Project Delivery Strategy and Scheduling,
Preliminary RA Schedule and Cost Estimate) and responding to all comments.
• Long-Lead Procurement Items (including submittal ofNPDES permit).
• Pre-Final Design for Groundwater Interim Remedy that incorporates any changes
since the preliminary design submittal, and responding to all comments.
Concurrently with the preparation of the Pre-Final Design, the Draft and Final
Subcontract Bid Documents will be prepared and submitted.
It is assumed that after completion of the above documents in this work assignment and
the selection of a qualified performance-based groundwater remediation contractor, EPA
Region 4 will complete the RA using these documents in a new work assignment under
EPA Contract 68-W-99-043 or similar contract vehicle.
A performance-type specification is anticipated for the groundwater interim RA as a
feature of the project delivery strategy. The two principal performance standards will be
as follows:
• Maintain a minimum system run time of 85%.
• Meet or exceed discharge criteria to be determined based on NPDES permit.
In addition, the sibcontractor will be required to provide performance and payment
bonds. Qualified RA subcontractors will be provided estimates of system influent
concentrations along with required maximum effluent concentrations ( as specified by the
NPDES permit). The selected subcontractor will be required to design, build, and operate
a treatment system capable of achieving the maximum allowable effluent concentrations.
Run times will be verified by run timers. Discharge compliance will be verified by
monthly sampling and analyses, or as otherwise specified by the NPDES permit.

Work Assignment No. 369-RDRD-A419
Preliminary Design Report for Groundwater Interim Remedy
Revision 0
September 7, 2005
Indications from the environmental services industry are that several potential treatment
technologies exist that are capable of achieving the groundwater cleanup goals (RAOs)
and/or groundwater discharge criteria specified by NPDES. All bid designs must consist
of pump and treat with physical/chemical treatment using air sparging, GAC, or
ultraviolet (UV) oxidation as specified in the IROD. Tertiary treatment may be necessary
for the removal of metals, including arsenic; activated alumina filters, anion exchange,
distillation, reverse osmosis, nanofiltration, iron oxide filters, and GAC filters (to some
extent) are treatment methods proven to remove inorganics. Additional bids may be
submitted to propose alternate remedial technologies. Bidders will be informed that they
are permitted to propose alternative remedial technologies to that specified by the IROD.
The objective of the interim RA is to reduce migration of contaminarts and prevent risks
to human health and the environment, not necessarily achieve RAOs. Therefore, the RA
subcontract should be structured such that if performance standards are exceeded then the
contractor would be financially rewarded. On the base case bid scenario, measurement
and payment items will be structured to allow flexibility in adjusting the constructed
remedial system as a component of the project delivery schedule.
The project delivery strategy will be in accordance with the Prime Contract, the Prime
Contract Small Business Utilization Goals, and the appropriate FAR clauses. A feature
of the project delivery strategy is to prepare the Final Contract Documents for subsequent
bidding and award to a Small Business. This will be accomplished by either pre-
qualifying only Small Businesses as potential subcontractors, or by giving preference to
Small Businesses in their bid evaluation. Preference may be given in a 10% price
differential or a weighted evaluation process that assigns higher points to a Small
Business as part of an overall evaluation process firms.
The groundwater interim remedy design assignment requires the preparation of draft
O&M specifications. In preparing these specifications, consideration will be given to
structuring tre Final Contract Documents such that Black & Veatch (EPA) has the right
to extend option periods in increments as specified below beyond the base period of the
subcontract, with pricing established at the beginning of the subcontract. The subcontract
base performance period will end June 16, 2006. Beginning June 17, 2006, Option I will
be executed for completion of RA Work Plan documents, pump and treat system

construction, start-up, and proveout for a period of approximately 4 months. Black &
Veatch then has the right to execute O&M options in I-year increments for the duration
of the interim RA (5-years of system operation). As the design develops for_ the RA,
Black & Veatch will consider the most cost effective method of completing the O&M for
the government. A final recommendation on O&M alternative contracting methods will
be included in the revised project delivery strategy to be submitted with the Final
Contract Documents.

9.0 Preliminary Cost Estimate
Revision 0
September 7, 2005
A preliminary RA construction cost estimate was prepared using Remedial Action Cost
Engineering and Requirements (RACER) software program as well as a standard spread
sheet estimate. Copies of the RACER outputs are provided in Appendix B. Costs of
individual components of the groundwater interim RA were estimated using RACER, and
these costs are summarized on Table 9-1 along with legal fees, permits, and other licenses
(5% of planning, design, and construction costs), contractor fee (10% of system
installation and components costs), and contingency (15% of planning, design, and
construction costs). The preliminary cost estimate for the total present worth cost of the
interim groundwater remedy at the Ram Leather Care is $754,071.
It is noted that the present worth preliminary cost estimate presented in this design report
is approximately 19 percent lower than the present worth cost estimate presented in the
FFS and !ROD. The most significant reduction in cost resulted from the difference is
system construction fees. The !ROD estimate included $148,000 for construction of a
building to house the pump and treat system; whereas, the preliminary RD costs instead
assumed the construction of a concrete pad, security fence, and canopy/awning to enclose
the system (total cost $7,594). This difference in building costs represents 13 percent of
the total disparity.
