Initial Site Sampling Plan -Former Rea Asphalt Plant
Boyle Project No. 05-203
1.0 INTRODUCTION
January 19, 2007
Final
The Subject Property consists of an approximate 8-acre site located at 2701 Youngblood Street
(also formerly identified as 121 Lancaster Street, 2801 Southview Avenue and 2820 Griffith
Street) in Charlotte, Mecklenburg County, North Carolina (Figure 1). The center of the
rectangular-shaped site is located at approximately N35° 12' 8" and W80° 52' 6". The site is
generally bounded by Youngblood Street to the northwest, Lancaster Street and the Mcleod
Addictive Disease Foundation, Inc. to the northeast, the Charlotte Light-Rail lines to the
southeast and commercial/industrial-use buildings along Griffith Street and Fairwood Street to
the southwest .
The property was most recently occupied by an asphalt plant owned and operated by Rea
Contracting, LLC (Rea) that was recently dismantled and removed from the property. The
former asphalt plant consisted of materials storage areas, aboveground storage tanks,
conveyors, silos and an office building (reportedly constructed in 1970). Figure 2 is a 2004
aerial photograph showing the general layout of the property prior to removal of the plant .
1.1 General Site History
The following site history summary is based upon a review of a Phase I Environmental Site
Assessment Report completed on the Subject Property by Geoscience Group, Inc., dated
December 20, 2005 and a subsequent review of additional historical resources by Boyle
Consulting Engineers, PLLC (BOYLE); as well as other referenced environmental assessment
reports, information obtained from persons familiar with the site, and observations made
during recent site activities. A list of the reports and historical resources reviewed is included
as Table 1.
From approximately 1931 to 1938, Charlotte Packing and Refining Company operated an
animal slaughterhouse/meat packing facility at the Subject Property, as did Charlotte Abattoir
from approximately 1940-1962. Based on a review of historical aerial photographs, and
Sanborn Fire Insurance Maps, this facility generally occupied the northern end of the Subject
Property .
By approximately 1966, an asphalt plant was operating in the southern end of the Subject
Property, near Griffith Street. The operation's address was reportedly 2820 Griffith Street .
Asphalt Materials Co., Inc./Carolina Paving Co., Inc. conducted operations there from 1967
through 1971. Based on conversations with Rea Contracting personnel familiar with the site,
there may have been a concrete plant in the southeastern end of the site during this time .
According to Mecklenburg County Tax Records, in 1970 the northern portion of the Subject
Property, near Lancaster Street, was developed as an asphalt plant; Rea Construction
Company operated the plant beginning around 1972. Southview Avenue, which was the
operation's address, later became Youngblood Street.
In 2003, the corporate parent of Rea Construction Company, J.A. Jones Construction Company,
declared bankruptcy. In October, 2003, Lane Construction Corp. purchased certain assets of
Rea Construction Company, including the Property, from the bankruptcy estate of J.A. Jones
Construction Company, and formed Rea Contracting, LLC .

Asphalt operations ceased at the Property in January 2006 and dismantling of the asphalt plant
began in March 2006. At this time, Rea Contracting LLC began removal of the recyclable
asphalt, concrete and several large stockpiles of crushed stone that formerly covered most of
the Property. In addition, as a condition of a pending property transaction, the grade of the
site was generally lowered to elevations shown on a 1958 City of Charlotte Topographic Map
and then generally raised to the elevations shown on a 1981 City of Charlotte Topographic
Map. This was intended to facilitate removal of asphalt, aggregate and other debris associated
with the former asphalt plant operations at the site .
1.2 Known Releases of Hazardous Substances and Petroleum Products
1.2.1 Previous Hazardous Substance Releases
From approximately 1970 through 1989, the North Carolina Department of Transportation
("NCDOT") operated an asphaltic testing laboratory on the Property. The laboratory was
formerly located in the northern portion of the site in the southern corner of the one-story
brick office building. The NCDOT laboratory reportedly utilized trichloroethene (TCE), 1,1,1-
trichloroethene (1,1,1-TCA) and carbon tetrachloride (CCI4) in the asphaltic testing process. In
June 1997, a Comprehensive Site Assessment (CSA) was completed for the Subject Property .
The site was referred to as NCDOT Asphalt Testing Site No. 27-57 and was assigned North
Carolina Department of Environment and Natural Resources (DENR) Groundwater Incident
Number 17443. The CSA and subsequent assessments examined the impact of chlorinated
solvents on groundwater and soils. In August 2002, a Corrective Action Plan (CAP) proposing
natural attenuation was submitted; it was approved in November 2002 by DENR's Aquifer
Protection Section ("APS"). Currently, NCDOT is conducting groundwater monitoring at the
Property under the direction of APS. Pursuant to a Memoranda of Agreement between the
NCDOT and DENR, the scope of the CSA and CAP was specifically limited to assessment and
remediation of TCE, 1,1,1-TCA, carbon tetrachloride, and their degradation products (cis-1,2-
dichloroethene, trans-1,2-dichloroethene, and vinyl chloride). For simplicity, thes~
constituents have been referred to as the "target compounds."
Soil contamination with the above target compounds was found to be generally limited to the
area immediately adjacent to the former laboratory (Figures 3 and 4 and Table 2). Other
"non-target compounds", including benzene, n-butylbenzene, sec-butylbenzene, tert-
butylbenzene, ethylbenzene, isopropylbenzene, p-Isopropyltoluene, methyl-tert-butyl ether,
naphthalene, n-propylbenzene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene and
xylenes, were also detected in the vicinity of the lab (Table 2). Concentrations of n-
butylbenzene, naphthalene, tert-butylbenzene, xylenes and ethylbenzene that exceeded DENR
Soil-to-Groundwater and/or Site Screening Levels (SSLs) were only detected at one sample
location (DP-14) .
Target compounds were also found in shallow ground water in the area around the laboratory
(Figures 5 and 6 and Table 3). Concentrations of cis-1,1-dichloroethene, trichloroethene and
vinyl chloride were detected above the 15A NCAC 2L groundwater quality standards (2L) for
these constituents. Non-target compounds, including benzene, bromodichloromethane, n-
butylbenzene, tert-butylbenzene, dibromochloromethane, diisopropyl ether, p-
isopropyltoluene, methyl-tert-butyl ether, naphthalene, n-propylbenzene, tetrachloroethene,
toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene and xylenes, were also detected in
the vicinity of the lab (Table 3). Concentrations of benzene, bromodichloromethane and

Final
dibromochloromethane were detected above the 2L groundwater quality standards for these
constituents .
1.2.2 Petroleum Underground Storage Tank Releases
In December 2005, an Underground Storage Tank (UST) Closure Report was submitted to
DENR's UST Section on behalf of Rea Contracting, LLC regarding an investigation into the
reported removal of an 8,000-gallon gasoline UST from the Subject Property in the mid-1980s .
The UST Section assigned Incident Number 36019 in connection with the investigation.
Subsequent investigation also found that two 20,000-gallon diesel USTs were also apparently
removed from the property in the mid-1980s. In July 2006, a Phase I Limited Site Assessment
(LSA) was completed. By letter dated August 14, 2006, the UST Section gave that incident "no
further action" status, and on August 21, 2006 a Notice of Residual Petroleum (NORP) was
recorded against the Property at the Mecklenburg County Register of Deeds' office. The NORP
was required due to the identification of groundwater contamination in excess of the 2L
groundwater quality standard. Benzene (6 ug/1), lead (310 ug/1), vinyl chloride (8.2 ug/1) and
TCE (74 ug/1) were detected in temporary monitoring well TW-3 at concentrations that
exceeded the 2L standard. The location of the former USTs and TW-3 are shown on Figure 7 ..
1.·2.3 Aboveground Storage Tank Release
The Rea asphalt plant located in the northern portion of the Subject Property had two
aboveground storage tanks (ASTs) that contained liquid asphalt that was supplied to the plant
. by underground and aboveground piping. One of the liquid asphalt ASTs was an approximate
150,000-gallon vertical AST. The second liquid AST was an approximate 20,000-gallon
horizontal AST. A third AST located in a concrete containment wall structure at the northwest
end of the plant was another approximate 20,000-gallon AST that contained diesel fuel. The
diesel fuel was also supplied to the plant via underground and aboveground piping .
After removal of the asphalt plant, petroleum contaminated soils were encountered beneath
the plant. Petroleum contaminated soils were excavated from an area approximately 90 feet
long by 10 feet wide and approximately 9-10 feet deep. Another shallow excavation
approximately 3-4 feet deep and covering an area approximately 10 feet by 20 feet, adjacent
to the deeper excavation was completed when removal of a concrete pad encountered minor
contamination directly beneath the pad. Analytical testing by Total Petroleum Hydrocarbon
(TPH) methods of soil samples from the horizontal and vertical extent of the excavations
confirmed removal of TPH-impacted soils above DENR APS standards. A Soil Contamination
Report (SCR) was submitted to the APS in· June 2006. In a letter dated, July 10, 2006, the
APS gave Incident No. 87791 "no further action" status. The locations of the excavations are
shown on Figure 7 .
1.2.4 Other Petroleum Releases
Area 2
During site grading activities, petroleum contaminated soils were encountered in the eastern
portion of the property (See Figure 7). Sampling and analytical testing of the soils found
concentrations of gasoline-range and diesel-range Total Petroleum Hydrocarbons (TPH) that
exceeded the TPH Action Levels of 10 ppm and 40 ppm, respectively. Between May 31 and July
31, 2006, BOYLE observed the excavation of this impacted area. The limits of the excavation

were based upon field screening levels utilizing a Foxboro lVA-1000, visibly stained soils and
petroleum odors. The final limits of the excavation were approximately 190 feet long by 110 feet
wide and up to 9-10 feet deep .
Confirmation samples collected from the sidewalls and bottom of the excavation and analyzed
for gasoline-range TPH and diesel range TPH. The analysis confirmed that TPH contamination
had been effectively removed from the lateral and horizontal extents of the excavation with the
exception of two areas .
In two areas, the excavation extended to depths of approximately 9-10 feet deep. Evidence of
groundwater was encountered in these two areas. Subsequently, two shallow groundwater
monitoring wells (SW-11 and SW-12) were installed and sampled. Laboratory analysis of the
two wells detected concentrations of benzene (130 ug/1), 1,2-dichloroethane (0.63 ug/1) and
diisopropyl ether (380 ug/1) in well SW-12 that exceed the 2L standards of 1 ug/1, 0.38 ug/1, and
70 ug/1, respectively. No constituents were detected at concentrations that exceed the 2L
standards in monitoring well SW-:-11. The groundwater sample results are summarized in Table
4 .
No apparent sources of the soil and groundwater contamination were readily identifiable during the
excavation activities. Persons familiar with the site indicated that petroleum products were
commonly utilized to free asphalt from the beds of asphalt trucks by spraying the bed with small
amounts of petroleum products, but this has not been confirmed as the source .
A Notice of Release (NOR) was sent to the APS on October 17, 2006. On December 6, 2006 a
Notice of Violation (NOV) was received from the APS for violation of the 2L standards. The NOV
assigned groundwater Incident No. 87948 to the release and required completion of a CSA by
March 6, 2007 .
On October 24.and 25, 2006, three shallow Type II groundwater monitoring wells (SMW-13, SMW-
14, and SMW-15) and one Type III groundwater monitoring well (DMW-3) were installed around
SMW-12. The wells were subsequently developed and sampled on November 1, 2006. The
concentration of benzene (1.1 ug/1) detected in DMW-3 was the only constituent detected above 2L
standards. The groundwater sample results are summarized in Table 4. Based on the preliminary
sample results it appears that the contamination around SMW-12 appears to be limited to the area
defined by SMW-11, SMW-13, SMW-14 and SMW-15. The CSA for Incident No. 87948 is currently
ongoing .
Area 3
During site grading activities, petroleum contaminated soils were encountered in the western
portion of the site, southwest of grade stake G-9 (See Figure 7). The petroleum contaminated· soils
were originally encountered near the 1958 grade elevation. The initial excavation was generally a
shallow (less than 2-3 feet) excavation below the 1958 grade until the vertical and horizontal
extents of the contamination were removed. Four confirmatory samples were collected from the
bottom of the shallow excavation and analyzed for gasoline-range TPH and diesel-range TPH .
Gasoline-range TPH was detected in two samples at concentrations of 15 mg/kg and 21 mg/kg
which exceed the APS action level of 10 mg/kg. Diesel-range TPH was also detected in the same
two samples at concentrations of 900 mg/kg and 260 mg/kg which exceed the APS action level of
40 mg/kg .

On November 13, 2006, a shallow Type II groundwater monitoring well (SMW-20) was installed .
On November 15, 2006 free product (diesel) was discovered in the well. On November 17,
2006, <0.01 ft of free product was measured in the well.
On December 13, 2006 removal of a previously unidentified concrete slab revealed another area
of petroleum contaminated soils with a heavy diesel odor adjacent to H-9. Between December
13 and December 15, 2006 petroleum contaminated soils were excavated and stockpiled. The
excavation was extended to a depth of approximately 10-12 feet below grade where evidence of
shallow groundwater was encountered. The horizontal limits of the excavation are shown on
Figure 7. On December 15, 2006, eleven samples were collected from the sidewalls of the
excavation. Diesel-range TPH was detected in one of the eleven samples at a concentration of
11,000 mg/kg, which exceeds the APS action level of 40 mg/kg. Gasoline-range TPH was also
detected in that same sample at a concentration of 15 mg/kg, which exceeds the APS action
level of 10 mg/kg. Additional excavation of this area was completed on January 16, 2006 .
Laboratory analytical results are still pending for the confirmation samples collected .
A NOR was submitted to the APS on January 5, 2007. No NOV assigning an Incident No. has yet
been received .
1.3 Site Topography
As indicated on the United States Geological Survey (USGS) Topographic Map, Charlotte East,
N.C. quadrangle, dated 1988 (photorevised 1993), the site is located at an elevation of
approximately 730 ft above mean sea level (Figure 1). The topographic gradient at the site is
generally to the west and northwest. The USGS topographic map shows a small water feature
(pond) in the central portion of the site. No apparent evidence of the pond was observed in the
recent or historical aerial photographs .
The site topography has been altered by the development of the site. The. 1958 City of
Charlotte Topographic Map {Figure 8), shows an intermittent drainage feature traversing the
central portion of the site generally from the east-southeast to the west-northwest and site
elevations ranging from approximately 741 ft to 722 ft above mean sea level. The intermittent
drainage feature appears to have been piped and covered by 6 to 8 feet of fill in a 1981 City of
Charlotte Topographic Map (amended with storm water drains in 1982). The site elevations
generally range between 740 feet and 726 feet above mean sea level.
1.4 Geology and Hydrogeology
1.4.1 Regional Geology
The Subject Property is located in the generally rolling terrain of the Piedmont Physiographic
Province of North Carolina. The Piedmont generally consists of low, rounded hills and long
rolling (northeast to southwest trending) ridges with incised creeks and river channels .
According to the Geologic Map of the Charlotte Region 1° x 2° Quadrangle, North Carolina, and
South Carolina, dated 1988, the Subject Property is located in the Charlotte Belt geologic
province and the underlying bedrock is composed of granitic rock (granodiorite) .
In-place chemical and physical weathering of parent rocks typically form residual soils in this
geologic region. This weathered rock is known as saprolite or residuum. Weathering is
5

Initial Site Sampling Plan -Former Rea Asphalt Plant

January 19, 2007
Final
facilitated by the presence of fractures, joints, and less resistant minerals in the rock. In areas
not altered by erosion, alluvial deposition or the activities of man, the typical residual soil profile
consists of clay-rich unconsolidated materials, transitioning to sandy silts and silty sands that
generally become increasingly consolidated with depth. The boundary between soil and rock is
not typically sharply defined. The transitional zone is termed "partially weathered rock" .
The occurrence and movement of groundwater in the Piedmont is typically within two separate
but interconnected water-bearing zones. A shallow water-bearing zone occurs within the
saprolite, and a deeper water-bearing zone occurs within the underlying bedrock .
Surface and subsurface drainage patterns provide an indication of the direction in which
contaminants, if present, would be transported by surface waters or groundwater. The
movement of groundwater through soil and rock is dependent upon the effects of geologic
features, such as bedding, faults, folds or foliation planes. Groundwater recharge within the
area occurs mostly from precipitation on upland areas above floodplains. The native soils act as
an infiltration medium for precipitation to seep into the fractures and joints of the underlying
bedrock. Discharge from the system occurs as seepage springs that are common near the bases
of slopes and at the intersection with surface water features such as streams and lakes .
1.4.2 Site Geology and Hydrogeology
Based on a review of the 1997 CSA, the 2002 CAP and the 2005 Preliminary Subsurface
Exploration, the geology of the site generally consists of competent bedrock at approximately
50-60 feet below ground surface (bgs), overlain by unconsolidated saprolite (mostly silty clays)
with areas of fill (sand, clay, asphalt, gravel, and debris) overlying the saprolite. The fill depths
generally range from 2-3 feet up to 10-15 feet .
Historical groundwater depths across the site generally range between 8 and 12 feet below
ground surface. The overall groundwater flow direction at the site is generally toward the west-
northwest. The hydraulic gradient in the northern portion of the site has been calculated at 0.03
ft/ft and the geometric mean hydraulic conductivity was previously calculated at 0.8 ft/day. The
groundwater velocity was also calculated at approximately 6 ft per year. The estimated shallow
groundwater potentiometric maps constructed from recent groundwater elevation data is shown
on Figure 9 .
1.5 Summary of Area Land Use and Potential Receptors
The Subject Property is located in an area characterized by mostly commercial and industrial-
use properties. The site is currently zoned TOD-M for Transit Oriented District-Mixed Use .
Preliminary development plans for the site have not been finalized, but BOYLE understands that
plans include a large mixed-use commercial/residential development .
The immediately surrounding area consists of mostly older light industrial and commercial
development. The new light-rail transit line is under construction along the southeastern
property boundary. The completion of the light-rail line is anticipated to increase redevelopment
of properties in the vicinity of the light-rail corridor .
Receptor surveys previously conducted as part of the CSA, CAP and Phase I LSA did not identify
water supply wells within a 1,500 foot radius of the Subject Property. Municipal water and
sewer are available to the Subject Property and surrounding area. The Charlotte-Mecklenburg

Utilities Department obtains the municipal water supply from Mountain Island Lake, located
approximately 10 miles north of the Subject Property .
Based on a review of the USGS topographic map (Figure 1), the site and surrounding properties
located on the northwest side of the adjoining railroad lines are located in the local drainage
area for Irwin Creek, which is located approximately 4,000 feet to the northwest. The adjacent
areas to the southeast of the railroad lines are located in the local drainage area for the Dairy
Branch of Sugar Creek, which begins approximately 800 feet to the southeast of the site. There
are no known surface water intakes in the vicinity of the Subject Property .
There are no known wellhead protection areas located within 1,500 feet of the site .
Given the location of the site within the Charlotte City limits and in an historically industrial and
commercial area, the existence of any environmentally sensitive areas is considered to be low .

2.0 Discovery and Source Characterization
2.1 Excavation
January 19, 2007
Final
After removal of the former Rea asphalt plant facility in March and April of 2006, grading
activities at the site began. The purpose of the grading operations was to remove any asphalt,
asphalt by-product, aggregate, and/or aggregate by-product that was likely a result of the Rea
asphalt plant operations. This generally entailed removal of these materials down to the grade
shown on the 1958 City of Charlotte Topographic Map. Once this grade was reached, and the
asphalt, aggregate, and by-products had been removed, the site was filled where necessary to
reach the grade shown on the 1981 City of Charlotte Topographic Map .
Due to the known soil contamination resulting from the former NCDOT asphalt testing
operations, the area around the former laboratory was not disturbed during initial site grading
activities. Based on the previous soil assessments, an area defined generally by grade stakes
C8, Bll, Dll and E8/E9 was flagged and left undisturbed while grading operations continued to
the north, south, and east of this area (See Figure 10). The vegetated area to the south
around the stormwater drain area was also left undisturbed .
On October 5, 6, 10 and 11, 2006, excavation of the flagged area was completed. The
excavation depths ranged between 4-5 feet near C8, 3-4 feet near B11, 6 feet near EB, and 7
feet near 011. Some areas beneath the former laboratory building were excavated to depths of
approximately 8-10 feet in order to remove the building foundation. Excavated materials were
placed in staging piles in the northern portion of the site pending waste characterization
analysis .
The excavated materials consisted of a mixture of undifferentiated materials including sand,
clay, gravels and miscellaneous metal, wood, plastic, concrete, and glass debris. No petroleum
or otherwise unusual odors were noted during the excavation process. In general, excavation
down to the 1958 grade removed the majority of the debris fill down to residual soils, which
were generally a red I tan silty clay near C8 and B11 that transitions to a grey organic (alluvial)
clay near E8 and 011.
After the flagged area had been excavated to the 1958 grade, a geotextile fabric was placed
across a large portion of the area to establish a firm base for placement of the engineered fill
necessary to return the site to the 1981 grade. The fill materials utilized consisted of suitable
materials screened to remove asphalt, debris and other unsuitable materials from other
portions of the site that were previously excavated from areas unaffected by known sources of
contamination .
2.2 Waste Characterization
On October 11, 2006, composite samples of the excavated soils from the flagged area were
collected for laboratory analysis. The analysis completed was based upon the known volatile
organic compound (VOC) contamination and analysis necessary for disposal at the Allied Waste-
CMS Landfill in Concord, North Carolina. Fourteen composite samples were collected for
analysis based on the estimated size and configurations of the staging piles. The composite
samples were analyzed for VOCs by EPA Method 8260, Total Petroleum Hydrocarbons by EPA
Methods 3550 and 5030, and Total RCRA 8 Metals by various methods. The laboratory results

are summarized in Table 5. Copies of the laboratory analytical results are included in Appendix
A .
Concentrations of volatile organic compounds, TPH, and RCRA 8 Metals were detected in the
composite samples analyzed. The concentrations detected were below levels acceptable for
disposal in a municipal solid waste landfill (MSWLF) as specified in the DENR Hazardous Waste
Section's "Contained-in" Policy for Soil Contaminated with Listed Hazardous Waste with the
exception of lead. Lead concentrations ranging between 73 mg/kg and 2,400 mg/kg were
detected. Thirteen of the fourteen samples contained concentrations of lead equal to or greater
than the 100 mg/kg allowed for disposal in a MSWLF. Upon receipt of the preliminary laboratory
results, the fourteen lab samples were analyzed by the Toxicity Characteristic Leaching Method
{TCLP). Based on the results of the sampling, it was confirmed that two staging piles
(containing an estimated 600 cubic yards of soil) contained levels of lead above the 5 mg/1 by
TCLP allowable for disposal in a MSWLF. Notice of the discovery was made to Ms. Roberta
Proctor, Hazardous Waste Section via US Mail in a letter dated November 1, 2006 .
2.3 Non-Hazardous Soil Disposal and Stabilization of Lead
In November 2006, the non-hazardous excavated soils were hauled to the Allied Waste-CMS
Landfill for disposal. Approximately 1,098 tons of non-hazardous soils were removed from the
site .
Approval to stabilize the lead in the excavated soils remaining at the site was received in a letter
from Ms. Proctor, dated November 17, 2006. Between December 4 and December 8, 2006, A&D
Environmental Inc. conducted the lead-stabilization activities. On December 4, 8, and 11, 2006,
composite samples were collected for laboratory analysis in accordance with the guidelines
specified in the November 17, 2006 letter. One composite sample was collected from each
approximate 25-cubic yard aliquout of treated material. A total of thirty (30) composite samples
were analyzed by TCLP for lead. In addition, one composite sample for each 200 yards of
treated material was analyzed using the Multiple Extraction Method (MEM) for lead. The MEM
samples were composited from the thirty (30) TCLP samples. The results are summarized in
Table 6 .
The results of the TCLP analysis only detected concentrations of lead above the method
detection limit of 0.025 mg/1 in six (6) samples. The highest concentration was detected in
sample LC-10A at 0.13 mg/1. This is less than the 5 mg/1, the concentration allowable for
disposal in a MSWLF as specified in the HWS "Contained-in" Policy .
Concentrations of lead were only detected above the method detection limit of 0.015 mg/1 in two
of the four composite samples analzed by the MEM. The highest concentration detected in the
Day 6 run for sample CB-lA, 0.0285 mg/1, is also less than 5 mg/1.
The results were submitted in a report dated January 11, 2007 with a request for approval to
submit the sample results to the Allied Waste-CMS Landfill for disposal as non-hazardous soils .
On January 17, 2007 the soils were removed from the site and disposed at the Allied Waste-CMS
Landfill .

2.4 Potential Source Identification
January 19, 2007
Final
The source of the lead contamination discovered in the excavated soils is unknown at this time.
Preliminary investigations were begun to attempt to identify the source and/or remaining extent
of contamination .
2.4.1 Preliminary Soil Sampling
On October 30, 2006, twelve soil borings were advanced in and around the area between C8,
B11, E8, and 011 (See Figure 10). Soil borings L-1 to L-12 were advanced utilizing direct-push
drilling techniques. The borings were advanced to depths of approximately 10 feet below the
existing grade (approximately the 1981 grade). Residual soils were encountered below the
engineered fill at five locations (L-1, L-8, L-9, L-10, and L-11) at depths ranging between 4 and
7 feet below 1981 grade. Pre-existing undifferentiated fill materials were encountered below
the engineered fill in the remaining seven locations (L-2, L-3, L-4, L-5, L-6, L-7 and L-12) at
depths ranging between 5 and 9 feet below the 1981 grade. The depth to the bottom of the
engineered fill was generally discernable by the presence of the geotextile fabric or other
visually apparent evidence .
Representative samples were collected from the residual soils or pre-existing fill materials for
laboratory analysis. The samples were placed in the appropriate laboratory-supplied
containers. The containers were labeled with pertinent sampling information (i.e. sample
designation, date and time) and then placed in an ice-packed cooler. The samples were
transported to Pace Analytical Services, Inc. (Huntersville, NC) for analysis of Total RCRA 8
Metals by various EPA Methods. The analytical results are summarized in Table 7. A copy of
the laboratory analytical data reports is included in Appendix B .
Concentrations of lead detected in residual soils ranged between 5.5 mg/kg and 12 mg/kg. The
concentrations detected in the pre-existing fill ranged between 15 mg/kg and 620 mg/kg. Only
the concentrations found in L-2, L-3 and L-5 were above the DENR Hazardous Waste Section
Site Screening Levels (SSLs) of 270 mg/kg and the EPA Region 9 Preliminary Remediation Goals
(PRGs) of 400 mg/kg .
Mercury (10 of 12 samples >0.0154 mg/kg), silver (2 of 12 samples >0.223 mg/kg), arsenic (2
of 12 samples >5.24 mg/kg), cadmium (9 of 12 samples >2.72 mg/kg) and chromium (8 of 12
samples >27.2 mg/kg) were also detected at concentrations that exceeded SSLs. Only arsenic
(10 of 12 samples >0.39 mg/kg) was detected at concentrations that exceeded PRGs .
2.4.2 Preliminary Ground Water Assessment
On November 13, 2006, five shallow groundwater monitoring wells were installed in the
northern portion of the site (See Figure 9). Monitoring well SMW-18 was installed adjacent to L-
2 (where the highest level of lead was detected in soils). The location of SMW-18 was also
located near the former western corner of the asphalt plant office building and TW-3 (where lead
had been previously detected in ground water as part of the Phase I LSA investigation of the
former gasoline UST). Monitoring well SMW-16 and SMW-17 were installed upgradient of SMW-
18 and monitoring well SMW-19 was installed downgradient of SMW-18 .
On November 15, 2006, monitoring wells SMW-16, SMW-17, SMW-18 and SMW-19 were
"developed" and groundwater samples obtained for laboratory analysis. The groundwater level

was initially measured and the volume of water in each well was calculated. The groundwater
depths were measured utilizing an electronic water level indicator and were determined to be
14.9 (SMW-16), 14.27 (SMW-17), 14.25 (SMW-18), and 13.45 (SMW-19) feet below the top of
casing. Groundwater removed from the wells as part of development was periodically sampled
and tested for consistency of pH, temperature and conductivity. When relatively consistent
readings of the above-described parameters were obtained, development was considered
complete. A minimum of three well volumes of water were removed from each well. The wells
were allowed to recharge to at least approximately 90 percent of the original volume prior to
sampling .
Well development and sampling were performed using a peristaltic pump with disposable
polyethylene tubing dedicated to each well. The groundwater samples were placed in laboratory-
supplied containers designated to each well. The containers were labeled with pertinent
sampling information (i.e. sample designation, date and time) and then placed in an ice-packed
cooler. The samples were transported to Pace Analytical Services, Inc. (Huntersville, NC) for
analysis for Total RCRA 8 Metals by various EPA Methods. The results of the analytical testing
are summarized in Table 4. A copy of the laboratory analytical data reports is included in
Appendix C .
Lead was only detected in one of the four wells sampled. The concentration of lead in SMW-19
(130 ug/1), exceeded the 2L standard of 15 ug/1. Concentrations of arsenic, barium, cadmium,
chromium and mercury were also detected in SMW-19. Only the concentration of cadmium
detected (1.9 ug/1) exceeded the 2L standard (1.75 ug/1) .
Barium was the only metal detected in the other three wells above laboratory detection limits .
The concentrations of barium detected were below the 2L standard .
2.4.3 Potential Sources
Observations made during original excavation activities, conversations' with Rea Contracting
personnel, a review of historical site information, and the results of preliminary assessment
activities have identified several hypothesis for the source of the lead and other metals
identified .
• An approximate 8,000-gallon gasoline UST was formerly located at the northwest end of
the former one-story building. The UST was likely in-use from the initial construction of
the plant (1970) until it was removed in the mid-1980s. Given the time that the UST
was in service it may have contained leaded gasoline, which if spilled during fueling of
the tank or that leaked from the tank or associated piping, may have caused or
contributed to the lead levels discovered .
During re-excavation of the former UST basin, petroleum-contaminated soils were
encountered and removed. TCLP analysis of the soils prior to disposal did not contain
levels of lead above 5 mg/1. As previously reported, lead was detected in temporary
monitoring well TW-3 installed in the former UST basin at a concentration of 310 ug/1 .
Development and sampling of the well was completed utilizing a disposable polyethylene
bailer. This sampling method generally produces higher sediment content than the
peristaltic pump used in the recent sampling and may be the cause of the higher
concentration detected .

Final
• A shop for repairing equipment and parts for the asphalt plant was located in the
northwestern end of the former one-story building. Operations that occurred in this area
likely involved the use of petroleum products, cleaners, paints and other chemicals which
may have been spilled or disposed of on the ground surface inside or outside of the shop
during early plant operations in the 1970s. BOYLE also understands that sand-blasting of
plant parts possibly painted with lead-based paint may have also occurred in this area .
• During excavation activities in the former lab area, pieces of hardened orange and red
sand were observed at various points. Subsequent discussions with Rea personnel
indicated that they may be pieces of foundry sand from the metal casting industry .
Laboratory analysis of a sample of the suspected foundry sand for total RCRA 8 Metals
only detected low levels of barium (2.7 mg/kg), chromium (0.81 mg/kg), lead (5.5
mg/kg) and mercury (0.0093 mg/kg). However, due to the limited sample collection and
analysis, this sample should not be considered representative of the possible
concentrations of metals found in foundry sand .
• During excavation activities in the former lab area, various metal, wood, glass and other
debris was discovered. This may be an indication that this area was filled with
contaminated debris from an unknown source .

3.0 Proposed Methods of Investigation
3.1 Constituents of Concern
January 19, 2007
Final
The purpose of the Initial Site Sampling Plan is to delineate the horizontal and vertical extent
of metals contamination at the site. Based on the preliminary sampling results we have
identified the following metals of potential concern .
3.1.1 Arsenic
Arsenic was detected above laboratory detection limits in 10 of the 12 preliminary soil samples
(L-1 to L-9, and L-11). The concentrations ranged between 0.66 mg/kg and 12 mg/kg. Only
the concentrations detected in L-6 (8.2 mg/kg) and L-5 (12 mg/kg) exceeded the SSL of 5.24
mg/kg. The concentrations detected in the 10 samples were all above the Region 9 PRG of
0.39 mg/kg. The detection limits (0.55 mg/kg and 0.64 mg/kg) for the other two samples also
exceeded the PRG. The concentrations of arsenic generally increase from <1 mg/kg in the
eastern portion of the sampling area to the highest levels of 8.2 mg/kg and 12 mg/kg in the
western portion of the sampling area .
Arsenic was only detected above laboratory detection limits in groundwater samples collected
from SMW-19. The concentration detected, 6.8 ug/1, does not exceed the 2L standard of 50
ug/1 .
3.1.2 Cadmium
-Cadmium was identified at concentrations ranging between 1 mg/kg and 8.4 mg/kg in the
twelve preliminary soil samples (L-1 to L-12). With the exception of L-4, L-9 and L-11, the
concentrations detected in the remaining samples all exceeded the SSL of 2.72 mg/kg. None
of the concentrations exceeded the Region 9 RBSL of 37 mg/kg. The preliminary sampling
results do not appear to do not delineate any discernable pattern of high and/or low
concentrations .
Cadmium was only detected above laboratory detection limits in groundwater samples
collected from SMW-19. The concentration detected, 1.9 ug/1, slightly exceeds the 2L standard
of 1.75 ug/1 .
3.1.3 Chromium
Chromium was detected at concentrations ranging between 12 mg/kg and 180 mg/kg in the
twelve preliminary soil samples (L-1 to L-12). With the exception of L-4, L-8, L-10 and L-12,
the concentrations detected in the remaining samples all exceeded the SSL of 27.2 mg/kg .
None of the concentrations exceeded the Region 9 PRG of 210 mg/kg. The highest
concentrations appear to be located between L-1 (180 mg/kg) and L-2 (47 mg/kg) and also
between L-6 (35 mg/kg) and L-7 (44 mg/kg) .
Chromium was detected above laboratory detection limits in in groundwater samples collected
from SMW-11, SMW-12 and SMW-19. The concentrations detected in SMW-11 (38 ug/1),
SMW-12 (27 ug/1) and SMW-19 (7.9 ug/1) do not exceed the 2L standard of 50 ug/1.

3.1.4 Lead
January 19, 2007
Final
Lead was detected at concentrations ranging between 5.5 mg/kg and 620 mg/kg in the twelve
preliminary soil samples (L-1 to L-12). The concentrations detected in L-2 (620 mg/kg), L-3
(530 mg/kg), and L-5 (620 mg/kg) exceeded the SSL of 270 mg/kg and the Region 9 PRG of
400 mg/kg. The preliminary sampling results indicate that the lead concentrations above the
SSL and Region 9 PRG appear to be limited to the area beneath the northwest end of the
former one-story building and the areas to the northwest and west of the former building .
Lead was only detected above laboratory detection limits in groundwater samples collected
from SMW-19. Lead was detected at a concentration of 130 ug/1, which exceeds the 2L
standard of 15 ug/1. Lead was also previously detected in temporary monitoring well TW-3 at a
concentration of 310 ug/1 .
3.1.5 Mercury
Mercury was detected at concentrations ranging between 0.0077 mg/kg and 0.66 mg/kg in the
twelve preliminary soil samples (L-1 to L-12). With the exception of L-8 and L-11, the
concentrations detected in the remaining 10 samples exceeded the SSL of 0.0154 mg/kg .
None of the concentrations exceeded the Region 9 PRG of 23 mg/kg. The preliminary sampling
results indicate that the highest mercury concentrations are located at L-7 (0.66 mg/kg).
Lower levels were found to the north (L-4, 0.042 mg/kg), east (L-8, 0.0077 mg/kg), west (L-6,
0.016 mg/kg), south (L-12, 0.031 mg/kg) and southeast (L-11, 0.0092 mg/kg). The area
beneath the northwest end of the former building (L-2) and northwest (L-3) and west (L-5) of
the building also had higher levels of mercury ranging between 0.12 mg/kg and 0.34 mg/kg .
Mercury was only detected above laboratory detection limits in groundwater samples collected
from SMW-19. The concentration detected, 0.31 ug/1, does not exceed the 2L standard of 1.05
ug/1 .
3.1.6 Silver
Silver was only detected in two soil samples above laboratory detection limits ( <0.69) (L-3 and
L-7). The concentrations of silver detected in L-3 {1.8 mg/kg) and L-7 (2 mg/kg) exceeded
the SSL of 0.223 mg/kg but not the Region 9 PRG of 390 mg/kg .
Silver was not detected above laboratory detection limits in groundwater samples collected
from SMW-16, SMW-17, SMW-18 and SMW-19 .
3.1.7 Soil Background Levels
Naturally-occurring metal concentrations can be established to determine site-specific
screening and cleanup levels. Due to the extensive use of almost the entire site for the former
asphalt plant operations as well as the proximity of the site to surrounding roadways, railroads
and other industrial developments, it may be difficult to determine true natural metal
concentrations in soil .
Published data is limited in the area of naturally-occurring concentrations of metals in soil. The
following table is a summary of data reviewed from the North Carolina Department of
Agricultural and Consumer Services, New York State Department of Environmental

3.2 Soil Sampling Plan·
BOYLE proposes to collect additional soil samples to further delineate the horizontal extent of
arsenic, cadmium, chromium, lead, mercury, and silver in the former building area unless site-
specific background levels can be established .
An attempt will be made to obtain background samples in areas that have a lower likelihood of
potential influence from facility activities, surrounding properties and transportation corridors .
Five to ten samples will be collected from locations shown on Figure 11. If it is possible to
establish reliable site-specific background levels for the site, the sampling locations detailed
below may be altered accordingly .
The existing grade stakes used for site grading are on approximately SO feet centers. Utilizing
the existing grid as a base, we have adapted the grid to include 20 feet centers. At this time
we propose to extend the search area by approximately 20-40 feet northwest, northeast and
southeast from the preliminary sampling area based on the preliminary sampling locations .
The area to the southwest will be extended approximately 40-80 feet from the preliminary
sampling area. This will explore the still undisturbed and vegetated area around the
stormwater detention feature for the site. Approximately 28 sample locations shown on Figure
11 will be sampled for the constituents of concern .

3.2.1 Soil Sample Depths
January 19, 2007
Final
Background Samples -Five to ten potential background samples will be collected from
locations shown on Figure 11. The samples will be collected at depths greater than 2 feet
below existing grade and no deeper than 8 feet below ground surface .
Horizontal Extent of Contamination -Samples obtained· from locations in previously cut and
filled areas will be sampled between· the base of the cut/fill and the shallow groundwater table .
Water levels measured in monitoring wells SMW-16, 17, 18 and 19 have been measured at
depths ranging between approximately 10.5 and 12 feet below existing grade. Only one
composite sample will be collected from locations with five feet or less of separation between
the cut elevation and the shallow groundwater table. Samples in undisturbed areas will be
collected from depths of approximately 0.5-1.5 feet below ground surface and at approximately
5 feet intervals until the shallow groundwater table is reached. Based on the measured
groundwater levels we anticipate sample collection depths at approximately 5-6 and 10-11 feet
bgs .
3.2.2 Soil Sample Collection Methods
Soil borings will be advanced utilizing direct-push methods wherever possible. The samples
will be collected at 4 or 5 feet intervals utilizing a stainless-steel tube lined with a PVC/PETG
sampling tube. Soil samples will be collected from the sampling tube utilizing disposable
gloves and will be placed in laboratory-supplied 8 oz. glass jars with Teflon lids. The jars will
be appropriately labeled and stored at 4°C for transportation to the laboratory under
appropriate chain of custody procedures .
It may be necessary to utilize stainless-steel hand augers to advance certain borings near
utilities and/or difficult to access areas. If so, a decontaminated auger will be used to advance
the boring just above the sample collection depth. The auger head will then be
decontaminated or replaced with a new decontaminated auger head prior to advancing the
auger head to the sample collection depth. After collection of the sample, the same auger
head may be used to advance the boring to just above the next sample collection depth before
being decontaminated or replaced as described above .
3.2.3 Soil Sample Analysis
The soil samples and Field QC samples collected will be submitted to a NC Certified laboratory
for analysis of total concentrations of arsenic, cadmium, chromium, lead, and silver by EPA
Method 6010B and mercury by EPA Method 7471.
3.3 Additional GW Assessment
Based on the results of the soil assessment, additional shallow Type II groundwater monitoring
wells will be installed. At this time, we anticipate installation of approximately 3 or 4 shallow
groundwater monitoring wells in the vicinity of SMW-19. At a minimum, one well will be
installed along the property boundary north of soil boring L-3; another well will be installed
along the property boundary southwest of SMW-19, and another well will be installed 50-100
feet south of SMW-19 (See Figure 11). ·

The monitoring wells will be installed using hollow-stem augers and will be installed to depths
approximately 15-20 feet below existing grade. The bottom of the well will be set at a depth
sufficient to screen the groundwater interface and allow for seasonal fluctuations in the
groundwater elevation .
No bedrock or deep monitoring wells will be installed at this time .
3.3.1 Groundwater Sample Collection Methods
The monitoring wells will be developed and sampled using low-flow techniques. The wells will
be developed and purged until pH, temperature, and specific conductivity stabilize. A
minimum of three well volumes will be removed from each well prior to sampling or after the
well has gone dry; purging twice .
3.3.2 Groundwater Sample Analysis
The groundwater samples collected will be submitted to a NC Certified laboratory for analysis
of total concentrations of lead and cadmium by EPA Method 6010 with Standard Method 3030C
sample preparation .
3.4 Standard Field Protocols
3.4.1 Quality Control Samples
The following Field QC samples will be collected:
• One duplicate sample per field day
• One field blank per field day
•· One equipment rinse blank per sampling event
• One trip blank per sampling event
3.4.2 Sample Location and Surveying
Soil sampling and boring locations will be staked and flagged until the investigation is complete
or until surveyed by a North Carolina Registered Professional Land Surveyor. In addition, all
monitoring wells and water level measuring point locations will be surveyed .

3.4.3 Field Decontamination Procedures
January 19, 2007
Final
Sampling equipment will be decontaminated utilizing phosphate-free laboratory detergent and
distilled water prior to being transported from the site. Cleaning will occur in a
decontamination pad constructed in an area believed to be free of surface contamination and in
a manner to prevent leakage and facilitate the removal of wastewater. Sampling equipment
will be cleaned between each sample boring and/or as described in Section 3.2.2 .
Cleaning of drilling equipment will also occur in the decontamination pad utilizing tap water and
a steam cleaner and/or high pressure hot water washer with a soap compartment. The drill
equipment will be cleaned between boreholes .
3.4.4 Investigation Derived Waste CIDWl
IDW, including soil cuttings, wastewater from 9econtamination procedures, groundwater from
well development or purging, and drilling mud or water will be placed into 55-gallon drums and
stored on-site until appropriate waste characterization can be completed and a method of
treatment and/or disposal is determined .
Non-hazardous IDW such as personnel protective equipment (PPE), disposable sample
equipment, and paper/plastic/cardboard wastes will be placed into municipal dumpsters for
disposal. Any potentially hazardous IDW will be placed into 55-gallon drums or 5-gallon
buckets and will be stored on-site for a maximum of 90 days while the appropriate waste
characterization is completed and treatment and/or disposal is determined .

Boyle Project No. 05-203
4.0 Schedule
January 19, 2007
Final
Upon approval of the proposed ISSP we propose the following schedule to conduct the ISSP:
• Complete background soil sampling within one to two weeks of approval
• Submit samples to laboratory for analysis on 7-10 business day turn around
• Within one week of receipt of background soil sampling results, submit request to HWS
for preliminary establishment of soil background levels
• Amend soil sampling plan accordingly, if necessary
• Within one to two weeks of approval from HWS complete soil sampling and submit
samples to laboratory for analysis on 7-10 day business day turn
• Within one week of receipt of soil sampling results, notify HWS of findings and proceed
with initial ground water sampling, amend sampling plan accordingly
• Within one to two weeks of approval from HWS complete groundwater sampling and
submit sample to laboratory for analysis on 7-10 business day turn .
• Within two to three weeks of receipt of groundwater sampling results submit findings
along with proposal for Assessment and Cleanup Plan (ACP) to HWS

In accordance with your letter, dated November 17, 2006, Boyle Consulting
Engineers, PLLC (BOYLE) has been requested by Mr. Bill Copeland, Rea Contracting,
LLC., to provide you with the analytical results for the above-referenced site .
Between December 4 and December 8, 2006, A&D Environmental Inc. stabilized
approximately 750 cubic yards of lead-impacted soils by the addition of TSP in
accordance with the guidelines established in the November 17, 2006 letter. On
December 4, 8, and 11, 2006, one composite sample was collected from each 25-
yard aliquot of treated material. A total of thirty (30) composite samples were
collected for laboratory analysis by the Toxicity Characteristic Leaching Procedure
{TCLP) for lead. In addition, one composite sample for each 200 yards of treated
material was collected for analysis using the Multiple Extraction Method (MEM) for
lead. The MEM samples were composited from the thirty (30) TCLP samples
The sample analytical results are summarized in the attached Table 1. Copies of the
laboratory analytical data reports are also attached .
The results of the TCLP analysis only detected concentrations of lead above the
method detection limit of 0.025 mg/kg in six (6) of the thirty samples. The highest
concentration detected in sample LC-10A at 0.13 mg/1. This is less than 5 mg/1, the
concentration allowable for disposal in a municipal solid waste landfill (MSWLF) as
specified in the · DENR Hazardous Waste Section's "Contained-in" Policy for Soil
· Contaminated with Listed Hazardous Waste .
Concentrations of lead were only detected above the method detection limit of 0.015
mg/1 in two of the four composite samples analyzed by the MEM. The highest
concentration detected in the Day 6 run for sample CB-1A, 0.0285 mg/1, is also less
than 5 mg/1 .
Based on the analytical results of the composite samples collected, we request your
approval to submit the sample results to the Allied Waste-CMS Landfill for disposal as
non-hazardous soils .

above site. The stabilization process is approved with the following guidelines:
1 The soil must be analyzed to ensure that there are no constituents of concern above the
NC Hazardous Waste Section SSLs that would not be stabilized by the addition of the
TSP.
2 The soil must be treated in no more than 25-yard aliquots. A composite sample must be
collected of each 25 yard aliquot that is treated to ensure that soil is adequately
stabilized.
3 After treatment and sampling, the soil may be placed into a soil pile following standard
practices for ensuring that run-on/ run-off is controlled, the pile is inspected each day
(including weekends) and a log of inspections maintained .
4 If the soil is to be placed on-site after treatment, the soil must be analyzed for all
constituents of concern and the levels must be below the level for unrestricted use as
specified in the Hazardous Waste Section's "Contained-in" Policy for Soil
Contaminated with Listed Hazardous Waste" located on our web-site at:
http://www. wastenotnc.org!hwhome/ guidance/pdf/Containedinpol icyMay2 00 5. pdf.
5 One composite sample of each 200 cubic yards of treated material must be analyzed
using the Multiple Extraction Method for lead.
6 The analysis in items 4 and 5 above must be reviewed by the Hazardous Waste Section
Compliance Branch Chemist prior to placing the soil on the land.
7 The treatment process must be completed within one month of the date of this approval
and all soil analysis submitted to this office within 6 weeks of the date of this approval.

Boyle Consulting Engineers, PLLC (BOYLE) has been requested by Mr. Bill Copeland,
Rea Contracting, LLC. to notify you of a discovery of lead-impacted soils at the above
referenced site. The lead-impacted soils were discovered during pre-disposal
sampling for suspected non-hazardous soils.
The Subject Property consists of an approximate 8-acre site that was most recently
occupied by a Rea Contracting asphalt plant. The site is currently undergoing
excavation and filling activities as part of grading activities for a pending real estate
transaction and eventual site redevelopment.
BOYLE understands that an asphalt testing facility was operated on the Subject
Property by the North Carolina Department of Transportation (NCDOT Site No. 27-
57) from around 1970 until about 1989. Chlorinated solvents reportedly used at the
facility included trichloroethene (TCE), 1,1,1-trichloroethane (1,1,1-TCA), and carbon
tetrachloride (CCI 4). Chlorinated solvents were first detected in groundwater in 1989
(Groundwater Incident No . 17443). Additional assessment confirmed soil and
groundwater contamination at the site. A Corrective Action Plan (CAP) was approved
by the North Carolina Department of Environment and Natural Resources (NCDENR)
in November 2002 that included monitored natural attenuation for groundwater and
required no soil remediation.
As part of the pending real estate transaction, the site grade was to be returned to
pre-development elevations shown on a 1958 City of Charlotte Topographic Map and
then returned to elevations shown on a 1981 City of Charlotte Topographic Map.
Since the excavations in the vicinity of the former NCDOT asphalt laboratory could
potentially disturb impacted soils, the excavated soils were temporarily stockpiled
on-site and sampled. Composite samples were collected and analyzed for
contaminants previously detected at the site (VOCs) by EPA Method 8260 along with
gasoline and diesel-range Total Petroleum Hydrocarbons (TPH). In addition, at the
request of the intended disposal landfill, samples were also analyzed for Total RCRA
8 Metals. Upon receipt of the preliminary laboratory results, it was discovered that
some of the stockpiled soils contained total lead concentrations that exceeded the

Boyle Project No. 05-203
November 1, 2006
Final
allowable concentrations for disposal in a Subtitle D Municipal Solid Waste Landfill
(MSWLF). Subsequent analysis by the Toxicity Characteristic Leaching Method
(TCLP) confirmed that two stockpiles (containing an estimated 600 cubic yards)
contained levels of lead above 5 mg/1 by TCLP. The laboratory results are
summarized in the attached Table 1.
At this time, there is no known or readily identifiable source for the lead
concentrations found. Additional assessment work to determine the potential extent
of residual lead contamination has begun but laboratory results are still pending.
Proposals for on-site treatment of the lead contaminated soils have been obtained.
The on-site treatment proposed will involve stabilization of the lead by the addition
of Triple Super Phosphate (TSP), with the intent of reducing the concentrations of
leachable lead below levels suitable for disposal in a Subtitle D MSWLF. The
proposals have been obtained from firms with recent experience on similar projects
in North Carolina under the supervision of the NCDENR Inactive Hazardous Sites
Branch. Upon receiving approval, the selected firm is prepared to mobilize to the
site to begin operations within approximately one week.
With this letter we are notifying you of our discovery and requesting your assistance
in insuring that the lead-contaminated soils are handled in accordance with
applicable regulations.
A copy of this letter is also being provided to the Mr. Andrew Pitner of the NCDENR
Aquifer Protection Section, Mooresville Regional Office who is currently overseeing
the NCDOT Groundwater Incident.
Thank you for you attention to this matter and please contact us with any questions
or concerns.
Sincerely,
BOYLE CONSULTING ENGINEERS, PLLC
