Response to NCDEQ Comments
Supplemental Soil Sampling Report / Removal Action Work Plan
Former Virginia-Carolina Chemical Corporation – Charlotte Site
Charlotte, Mecklenburg County, North Carolina
NCN 000 410 661
Dear Mr. Mattison:
This letter confirms receipt of the North Carolina Department of Environmental
Quality (NCDEQ) Division of Waste Management Superfund Section’s comments
dated April 4, 2017 on the Supplemental Soil Sampling Report / Removal Action
Work Plan for the Former Virginia-Carolina Chemical Corporation Charlotte Site,
Charlotte, Mecklenburg County, North Carolina (the Site). On behalf of
ExxonMobil Environmental Services Company (EMES), Arcadis G&M of North
Carolina, Inc. (Arcadis) has prepared the letter to respond to the received
comments. The format below includes the NCDEQ’s comments followed by the
associated response.
Comment #1: Supplemental Sampling Activities
The sixth and seventh sentences of the third paragraph of the section entitled
Supplemental Sampling Activities state “Only one sample (CH-SB-108-TCLP; 0
to 2 feet bgs) contained TCLP lead at a concentration above the regulatory
standard of 5 mg/L. TCLP results for all other samples and constituents were
either not detected or were present at concentrations below the regulatory
standards.” However, Table 2 – Summary of Waste Characterization Analytical
Results indicates that three samples (CH-SB-51 (0 to 2 feet below ground
surface (bgs)), CH-SB-94 (0 to 4 feet bgs), and CH-SB-108 (0 to 2 feet bgs))

contained TCLP lead at a concentration above the regulatory standard of 5 milligrams per liter (mg/L).
Please clarify this discrepancy.
Response #1:
Only one sample (CH-SB-108-TCLP; 0 to 2 feet bgs) analyzed for TCLP arsenic and lead during the
February and March 2017 event exceeded the RCRA standard of 5 mg/L. Table 2 also includes a five
TCLP sample results from 2011 and 2012 that fall within the current removal area. Removal in these
areas was previously limited due to utilities and/or structures. Since some utilities and structures are
being removed as part of the redevelopment, additional soil removal is planned in these areas. Language
has been added to the section entitled Supplemental Sampling Activities to clarify the samples and
results summarized in Table 2.
Comment #2: Proposed Soil Removal Activities
Figure 4 – Proposed Soil Removal Areas and Depths of Impacted Soil indicates that soil samples
collected from soil sampling locations SB-07, SB-10, SB-11 and SB-25 exceeded the site-specific action
levels (SSALs) for arsenic and lead. Please revise the section entitled Proposed Soil Removal Areas to
indicate how the aforementioned areas will be addressed (i.e., identification and land use restrictions
recorded with the Mecklenburg County Register of Deeds).
Response #2:
Soil borings SB-07, SB-10, SB-11, and SB-25 are in asphalt parking areas on PIN # 12103220 which is
not being redeveloped at this time. Both PIN #12103220 and #12103217 are under a Brownfields
Agreement which limits future use of the property. If PIN #12103220 is redeveloped in the future, the soil
in the vicinity of these borings will be addressed. Additional text has been included at the beginning and
end of the Proposed Soil Removal Activities section clarifying how impacted soils at the referenced
locations will be managed in the future.

Revised Supplemental Soil Sampling Report/Removal Action Work Plan
Former Virginia-Carolina Chemical Corporation Site
Charlotte, North Carolina
Dear Mr. Mallary:
This letter presents the findings of soil sampling activities performed by Arcadis,
G&M of North Carolina, Inc. (Arcadis) on behalf of ExxonMobil Environmental
Services Company (EMES) at the former Virginia-Carolina Chemical Corporation
(VCC) Site located in Charlotte, Mecklenburg County, North Carolina (the Site).
This letter also includes plans for supplemental soil removal activities to be
performed based on the results of the sampling activities. The proposed soil
removal activities will be performed on a portion of the Site recently purchased by
P7/PSREG Tremont LLC (PIN # 12103217) that is being redeveloped under a
Brownfields Agreement (Brownfields Project Number: 18004-14-060).
Site Description
The Site is located in Charlotte, Mecklenburg County, North Carolina and is
surrounded by high density residential, commercial, and light industrial facilities.
The street addresses that match the parcel being redeveloped include: 327, 337,
339, and 349 West Tremont Avenue. A site map is included as Figure 1.
VCC owned the Site from approximately 1926 until 1970. Historical deeds indicate
that VCC merged into Socony Mobil Oil Company, Inc. in 1963, and the company
name changed in 1966 to Mobil Oil Corporation. Mobil Oil sold the property to Swift
Agricultural Chemical Company in 1970, and in 1973 W.D. Cornwell, Sr. and C.D.
Spangler, Jr. purchased the property. The former VCC property has since been
owned by several entities. In June 2014, Carolina Capital Investment Partners
(CCIP) Tremont, LLC purchased the property and on November 5, 2015, the
property entered into a Brownfields Agreement. In January 2017, the property was

subdivided and the western portion (PIN # 12103217) was purchased by P7/PSREG Tremont, LLC. CCIP
Tremont, LLC still maintains ownership of the eastern portion of the property (PIN # 12103220).
Site Background
VCC operated a former phosphate fertilizer plant at the Site. A review of available historical Sanborn maps
confirmed that the VCC Charlotte facility was a complete plant, with acid production facilities. Fertilizer
manufacturing began at this site prior to 1890 and continued until sometime between 1929 and 1934.
Historical documents indicate that the last year for acid production was 1934. During manufacturing, the
facility had a single acid chamber structure that was replaced sometime between 1911 and 1929. In addition
to the acid chamber, sulfur burners were present on-site in the 1890’s and early 1900’s, indicating that the
plant burned sulfur in the production of acids. Waste byproducts associated with the fertilizer manufacturing
process contained elevated concentrations of arsenic and lead.
Summary of Previous Investigations and Removal Actions
Site investigation activities were conducted between 2010 and 2012 to delineate the horizontal and vertical
extent of arsenic and lead concentrations in soil associated with the former VCC fertilizer plant. Investigation
activities were conducted in accordance with work plans reviewed and approved by both the United States
Environmental Protection Agency (USEPA) and the North Carolina Department of Environmental Quality
(NCDEQ). Arsenic and lead concentrations were detected in soil samples above USEPA’s site-specific
action levels (SSALs) of 27 milligrams per kilogram (mg/kg) and 270 mg/kg, respectively. The results of
these investigations were described in the Site Delineation Report and Removal Action Work Plan, Former
Virginia-Carolina Chemical Corporation Site, Charlotte North Carolina (SDR/RAWP; Arcadis, 2012).
In accordance with an Administrative Settlement Agreement and Order on Consent (AOC; Docket No.
CERCLA-04-2013-3762) between USEPA and ExxonMobil Oil Corporation, soil removal activities were
initiated at the Site in November 2013 and completed in March 2014. The objectives of the removal activities
were to remove accessible arsenic- and lead-containing soils (i.e., those soils not covered by buildings or
asphalt/concrete pavement) above the SSALs associated with the former fertilizer manufacturing activities,
and restore the Site to pre-excavation conditions, as appropriate. If concentrations of arsenic and/or lead
were above the SSALs, and additional soil removal was not practical due to the structural stability of existing
features (i.e., buildings or parking lots) or utilities, the area was physically marked with a demarcation liner
(orange plastic construction fencing) that was placed at the base of the excavation prior to backfilling. The
removal areas, approximate soil removal depths, and locations of demarcation liner are presented on
Figure 2. The details of the soil removal activities are described in the Removal Action Completion Report,
Former Virginia-Carolina Chemical Corporation Site, Charlotte North Carolina (Arcadis 2015).
Supplemental Sampling Activities
As part of the redevelopment of the property owned by P7/PSREG Tremont, LLC, the current buildings and
asphalt parking areas will be removed and the Site will be re-graded to facilitate the construction of new
commercial/residential facilities. Prior to this work, supplemental soil samples were collected on behalf of
EMES. The objective of sampling activities was to evaluate the magnitude and extent of arsenic and lead
in soil beneath these features that may otherwise be disturbed during redevelopment. These data, in
conjunction with data obtained during previous site investigation activities, will be used to develop an
appropriate removal action strategy to be implemented prior to redevelopment.

In January and February 2017, the aboveground portions of buildings in the areas to be redeveloped were
removed on behalf of P7/PSREG Tremont, LLC. Following building removal, supplemental soil sampling
activities were completed. Between February 27th and March 1st, 2017, soil samples were collected from
13 locations (CH-SB-103 through CH-SB-115) to complete the delineation of arsenic and lead. Soil samples
were collected either through the building slabs or the asphalt parking lot using hand augers and/or direct
push techniques. All soil samples were screened in the field using a portable XRF device. Soil samples
were collected from 0 to 0.5 feet, 0.5 to 2 feet, and in 2-foot intervals thereafter until XRF results for arsenic
and lead were less than the SSALs, refusal was encountered, or the maximum depth required for Site
redevelopment was reached. All soil samples collected from 0 to 4 feet were analyzed for arsenic and lead;
and samples were analyzed from successively deeper intervals until the concentrations of arsenic and lead
were below the SSALs. Analytical results obtained as part of this sampling event and during previous
investigations are presented in Table 1. Soil sample locations are shown on Figure 3. Laboratory analytical
reports are included in Attachment 1.
As part of the supplemental soil sampling activities, waste characterization samples were collected to
evaluate soil handling and disposal requirements. A total of 17 samples were analyzed for arsenic and lead
in accordance with the Toxicity Characteristic Leaching Procedure (TCLP). In addition, at the request of the
intended disposal facility, one sample was analyzed for TCLP VOCs, TCLP SVOCs, TCLP metals, and
PCBs. In general, these waste characterization samples were collected as composites from the ground
surface to the maximum depth at which arsenic and/or lead were present at concentrations above SSALs.
Detected concentrations were compared to the Resource Conservation and Recovery Act (RCRA)
standards described in 40 CFR Part 261.24. Only one sample collected during this investigation (CH-SB-
108-TCLP, 0 to 2 feet bgs) contained TCLP lead at a concentration above the regulatory standard of 5
mg/L. TCLP results for all other samples and constituents were either not detected or were present at
concentrations below the regulatory standards. A summary of the waste characterization results obtained
as part of this sampling event and during previous investigations are presented in Table 2. Based on the
previous investigations, two additional samples (CH-SB-51 [0 to 2 feet bgs] and CH-SB-94 [0 to 4 feet bgs])
contained TCLP lead at concentrations above the regulatory standard of 5 mg/L. Laboratory analytical
reports are included in Attachment 1.
Proposed Soil Removal Activities
Supplemental soil removal activities will be performed on behalf of EMES to address arsenic- and lead-
containing soils above the SSALs in areas that may otherwise be disturbed during site redevelopment. As
previously described, site redevelopment will be confined to PIN#12103217. Impacted soils on the adjacent
parcel (PIN#12103220) are currently below the asphalt parking lot and will be addressed in the future should
this cover be removed. Unless otherwise specified, this supplemental removal action will be conducted in
general accordance with the means and methods previously described in the approved SDR/RAWP.
The limits of soil removal have been determined as follows. In defining the horizontal limits of soil removal,
each soil boring has been assigned a certain area, or polygon. The size and shape of each polygon is
based on a number of factors including the location of adjacent soil boring locations, distinguishing features
such as the footprint of existing structures, and professional judgement. The vertical limits of soil removal
will be determined in the field during excavation activities. In general, the excavation depths will be based
on either the maximum depth at which arsenic and/or lead were detected above the SSALs, or the
presumed depth to which soils may be disturbed during site redevelopment activities; whichever is more
shallow. In areas where the maximum excavation depths are based on site redevelopment activities, EMES’
contractor will excavate at least 12 inches below the depth to which soils would be disturbed by the property

owner’s contractor. In general, the maximum depth of excavation is expected to vary from 1 to 6 feet below
ground surface. However, in some areas deeper excavation may be required to remove subsurface utility
lines and/or facilitate the future construction of a pool or other features. The horizontal limits and maximum
depth of impacted soils for each polygon are illustrated in Figure 4. A calculation of the overall volume of
impacted soils is provided in Table 3.
Prior to soil removal, site preparation activities will be conducted. These activities include, but are not limited
to, installation of erosion control measures, identification and location of utilities, surveying of removal area
boundaries, and construction of support areas. Temporary 6-foot chain link fence panels will be placed at
the perimeter of the work areas to prevent unauthorized entry during the work. In addition, temporary
lighting and security personnel will be used to deter entry into the work areas during off-work hours.
Soil removal will be performed using a combination of mechanical equipment and manual shoveling.
Concrete, bricks and/or asphalt in contact with the impacted soils will be managed in the same manner as
the underlying soils. As described previously, waste characterization samples were collected as part of the
supplemental soil sampling activities. These results, and/or results obtained during the previous
investigation activities, will be used to dictate how impacted soils will be managed. Soils excavated from
polygons where TCLP arsenic and lead concentrations are below 5 mg/L will be disposed of at a RCRA
Subtitle D landfill. Soils with TCLP arsenic or lead concentrations greater than or equal to 5 mg/L will be
stabilized on site and tested prior to off-site disposal at a RCRA Subtitle D landfill. In the event that
stabilization is not effective in reducing the leachable concentrations of arsenic and lead to below 5 mg/L,
these materials shall be disposed of off-site at RCRA Subtitle C land disposal facility. The following
prospective landfills have been selected for this project:
RA Subtitle C Landfill:
Chemical Waste Management, Inc. Landfill
36964 Alabama Highway 17 North
Emelle, AL 35459
Haz. Waste Facility ID #ALD000622464
RCRA Subtitle D Landfill:
Republic Services Charlotte Motor Speedway Landfill
5105 Morehead Road
Concord, NC 28027
Polygons containing soils that require stabilization prior to disposal in a Subtitle D landfill are illustrated in
Figure 4.
In areas where the maximum depth of excavation is expected to be less than the depth disturbed during
site redevelopment work, confirmation soil samples will be collected from the base of the excavation to
guide the depth of soil removal. Initially, confirmation samples will be screened in the field for arsenic and
lead using an XRF. Samples below the SSALs will be submitted to the analytical laboratory for verification.
If XRF or analytical results are above the SSALs, successive rounds of excavation and confirmation

sampling will be performed until either results are below the SSALs, or the excavation depth is equivalent
to the maximum depth of potential disturbance.
Confirmation samples will be collected from individual subareas excavated to the same depth at a frequency
not to exceed one sample (5-point composite) per 5,000 square feet of excavation. Confirmation soil
samples will be collected from the base of the excavation from 0 to 6 inches bgs and will be analyzed for
total arsenic and lead. Samples, including field quality control samples, will be collected, analyzed, and
validated in accordance with the procedures described in the previously approved Field Sampling Plan and
Quality Assurance Project Plan included in the SDWP.
If analyses indicate arsenic and lead concentrations are below the SSALs, the excavation area will be
backfilled to original grade with general fill materials. In all other areas, a demarcation liner consisting of
orange construction fence (or equivalent) will be placed at the base of the excavation prior to backfilling.
The demarcation liner will serve as a visual indicator of the interface between backfill materials and
potentially impacted soils to persons that may perform subsurface work in the future. Areas of demarcation
liner will be surveyed for future reference. As previously mentioned, both PIN # 12103217 and 12103220
are under a Brownfields Agreement which limits future use of the property.
Schedule
It is EMES’ intent to initiate soil removal activities upon USEPA and NCDEQ’s approval of this letter. As
these soil removal activities will be performed as part of the previously-executed AOC, no state or local
permits will be obtained for any of the work performed on Site consistent with 40 CFR 300.400(e). Unless
otherwise specified in this letter, all field sampling activities and laboratory analyses will be performed in
accordance with the previously-approved SDWP; and all soil removal activities will be performed in
accordance with the previously approved Removal Action Work Plan (Arcadis, 2012).
