approximately 32,000 cubic yards of soil have already been transported to the receiving site. It is
anticipated that an additional 2,000 cubic yards from the northern excavation pit has yet to be
excavated and transported to the receiving site. The purpose of this assessment wasgird to
determine whether the soil not yet evaluated from Grids 23, 24, and 30 is suitable for off-site
disposal (approximately 1,000 cubic yards).
Following removal of the tree cover and construction of sediment control fencing and a temporary
pond (located on the southeastern corner of the Brownfields Property), Progress gridded the
approximate area of anticipated cut into 35 distinct units. Each grid measured approximately 80
feet by 80 feet. Due to the presence of the temporary sediment pond and its stockpile of soil
(located in the northwestern portion of the site), Progress was unable to lay out each of the thirty
five grids at the time of sampling. Progress completed soil sampling within 30 of the defined
sampling grids.
On September 3 through September 5, 2019 Progress was on-site with 3D Environmental
Investigations, LLC, a North Carolina licensed well driller, to advance the soil borings within each
of the accessible grids. The soil borings were advanced using a Geoprobe™, which utilized the
direct push sampling method, and/or a hand auger (Figures 2 and 3). Progress advanced five soil
borings in each of the defined areas to an approximate depth of four feet below land surface (bls).
In an effort to establish uniformity, the soil borings in each grid were labeled similarly. The soil
boring in the southwestern corner was labeled “A”, the soil boring in the southeastern corner of the
grid was labeled “B”, the soil boring in the northeastern corner of the grid was labeled “C”, the soil
boring in the northwestern corner of the grid was labeled “D”, and the soil boring from the center
of each grid was labeled “Center”. The four corner soil borings were located 10 to 15 feet
diagonally from the staked corner of each grid. Soil samples were collected from depth intervals of
0-2 feet bls and 2-4 feet bls. A representative sample from each soil boring interval was placed
into two separate pre-labeled plastic baggies. Following adequate time one baggie from each
sample interval was screened using a photoionization detector for the presence of volatile organic
vapors. Progress utilized a pre-calibrated MiniRae 3000 equipped with a 10.6 eV Lamp. The
photoionization detector (PID) was calibrated in the laboratory using isobutylene (100 parts per
million) prior to shipment to the field, utilizing a correction factor for chlorinated solvents. The
distinct soil samples from each sampling interval were composited into one soil sample for each
grid unit. The composite sample from each of the grid units represented a total of ten soil samples
from each grid. Progress utilized the soil sample from the second baggie of the sample which
indicated the highest PID reading for laboratory analysis for volatile organic compounds (VOCs).
The composite samples were analyzed for semi-volatile organic compounds (SVOCs) using EPA
Method 8270, for Total Resource Conservation Recovery Act (RCRA) Metals using EPA Method
6020, and hexavalent chromium using EPA Method 7199. The soil sample that exhibited the
highest reading when screened with the PID from each grid was analyzed for VOCs using EPA
Method 8260.
Progress also collected and tested a soil sample from the receiving site. Progress advanced a soil
boring to an approximate depth of five feet bls. A soil sample from the terminus of the boring was
selected for laboratory analysis. The soil sample from the receiving site was collected below the
proposed cut depth on the receiving site in that location. The soil sample from the receiving site

was analyzed for VOCs using EPA Method 8260, for SVOCs using EPA Method 8270, for Total
RCRA Metals using EPA Method 6020, and hexavalent chromium using EPA Method 7199.
The soil samples were placed into laboratory prepared containers and then into a cooler packed
with ice, a trip blank, a temperature blank, and delivered under chain-of-custody to a North
Carolina certified laboratory. QA/QC documentation was provided. Progress requested a Level II
Data Package from the laboratory. Additionally, Progress requested that the laboratory report the
results to the method detection limit. The duplicate samples were analyzed using the
aforementioned methods. The assessment activities were completed per the Inactive Hazardous
Sites Branch, Guidelines for Assessment and Cleanup (October 2015).
The results of the soil sampling indicated the presence of Total RCRA Metals and VOCs in each of
the soil samples collected for laboratory analysis. Specifically, arsenic was detected in each of the
soil samples, with the concentrations of arsenic detected in soil sample Grid 6 exceeding its
Industrial/Commercial Preliminary Soil Remediation Goal (PSRG). Based on the low level
concentrations of arsenic detected and the presence of arsenic in each of the soil samples, it is
Progress’ opinion that the concentrations of arsenic detected reflect naturally occurring
concentrations and are not representative of evidence of a release. Hexavalent chromium was
detected in soil samples Grid-6 (1.38 mg/Kg), Grid 9 (0.528J mg/Kg), Grid 21 (0.438J mg/Kg), and
Grid 32 (0.507J mg/Kg) at concentrations exceeding its Residential PSRG. Additionally,
methylene chloride (0.0256J mg/Kg) was detected in soil sample Grid 1 at a concentration
exceeding its Residential PSRG. The remaining detected compounds were detected at
concentrations not exceeding their respective Protection of Groundwater PSRG.
The receiving site did not exhibit concentrations exceeding their respective Protection of
Groundwater PSRGs.
Because of site development constraints, it is necessary to transport soil from the Brownfields
Property to the receiving site. Since the export of soil exhibiting concentrations of targeted
compounds exceeding the applicable standards is not allowed if the receiving site does not also
exhibit concentrations of the same compounds, additional sampling of the Brownfields Property
was proposed.
On October 10 and 11, 2019 Progress and 3D Environmental Investigations returned to the site to
complete additional sampling on the Brownfields Property. Specifically, soil samples were
proposed to be collected from the existing stockpile located on the northwestern corner of the site,
from the area of proposed excavation pits along the northern property line to an approximate depth
of five feet bls, and from Grids 2 through 4, Grid 5, and Grid 7 collected at a depth of ten feet bls.
The location of the additional soil sampling grids and stockpile are depicted on Figures 2 and 3.
According to volumetric calculations and drone aerial photography, the stockpile consists of
approximately 2,100 cubic yards. Per NCDEQ protocol, one composite sample per 1,000 cubic
yards is required to characterize the stockpile. Progress attempted to divide the stockpile into three
equal volumes (Figure 2). Progress advanced three soil borings in each subdivided area of the
stockpile, driving the GeoprobeTM onto the stockpile. Each boring was advanced until evidence of
native material was encountered (i.e. hard soil and organics). Soil borings advanced in the area
defined as SP-1 were advanced to an approximate depth of 15 feet below the top of the stockpile,

soil borings advanced in the area defined as SP-2 were advanced to an approximate depth of ten
feet below the top of the stockpile, and soil borings advanced in the area defined as SP-3 were
advanced to an approximate depth of five feet below the top of the stockpile.
Eight distinct grids were marked in the field along the northern property line (EP-1 through EP-8).
The grids were measured to be approximately 50 feet by 80 feet, with the exception of Grid 6,
which measured approximately 50 feet by 48 feet. Soil borings in grids EP-1 through EP-8 were
advanced to approximate depths of five feet bls. Lastly, additional soil borings were advanced to
greater depths (ten feet bls) in grids located adjacent to the grids previously identified as having a
targeted compound at a concentration exceeding its Residential PSRG. Specifically, Progress
drilled soil borings in Grid 2, Grid 3, Grid 4, Grid 5, and Grid 7. Progress collected soil samples
from intervals of 4-6, 6-8, and 8-10 feet bls.
Progress advanced five soil borings in each grid area. In an effort to establish uniformity, the soil
borings in each grid were labeled in the same manner as the original grid sampling methodologies.
The soil boring in the southwestern corner of the grid was labeled “A”, the soil boring in the
southeastern corner of the grid was labeled “B”, the soil boring in the northeastern corner of the
grid was labeled “C”, the soil boring in the northwestern corner of the grid was labeled “D”, and
the soil boring in the center of the grid was labeled “Center”. The four corner soil borings were
located 10 to 15 feet from the staked corner of each grid. Soil samples collected from grids EP-1
through EP-8 were collected from depth intervals of 0-2.5 feet bls and 2.5-5 feet bls. Soil samples
collected from grids previously sampled but selected to be drilled to deeper depths EP-1 through
EP-8 were collected from depth intervals of 4-6 feet bls, 6-8 feet bls, and 8-10 feet bls. A
representative sample from each soil boring interval was placed into two separate pre-labeled
plastic baggies. Following adequate time one baggie from each sample interval was screened using
a PID for the presence of volatile organic vapors. Progress utilized a pre-calibrated MiniRae 3000
equipped with a 10.6 eV Lamp. The PID was calibrated in the laboratory using isobutylene (100
parts per million) prior to shipment to the field, utilizing a correction factor for chlorinated
solvents. The distinct soil samples from each sampling interval were composited into one soil
sample for each grid unit. The composite sample from each of the grid units represented a total of
ten soil samples from each grid. The second baggie of the sample which indicated the highest PID
reading was placed into laboratory containers for laboratory analysis. The results of the PID
screening are summarized in Table 1.
The composite samples were analyzed for SVOCs using EPA Method 8270, for Total RCRA
Metals using EPA Method 6020, and hexavalent chromium using EPA Method 7199. The soil
sample that exhibited the highest reading when screened with the PID from each grid was analyzed
for VOCs using EPA Method 8260.
The soil samples were placed into laboratory prepared containers and then into a cooler packed
with ice, a trip blank, a temperature blank, and delivered under chain-of-custody to a North
Carolina certified laboratory. QA/QC documentation was provided, and two duplicate soil samples
were collected (EP-11 and Grid 77). Progress requested a Level II Data Package from the
laboratory. Additionally, Progress requested that the laboratory report the results to the method
detection limit. The duplicate samples were analyzed using the aforementioned methods. The
assessment activities were completed per the Inactive Hazardous Sites Branch, Guidelines for
Assessment and Cleanup (October 2015).

The soil sample collected from the deeper interval of Grid 5 indicated concentrations of hexavalent
chromium at a concentration that exceeds its Residential PSRG. Laboratory analysis of the remaining
composite soil samples and discreet soil samples from the stockpile did not exhibit VOCs, SVOCs, or
Total RCRA Metals at concentrations that exceed the Protection of Groundwater PSRGs, with the
exception of arsenic. The concentrations of arsenic exceed the Residential and/or
Industrial/Commercial Health Based PSRGs. Progress does not consider the concentrations of arsenic
detected to represent evidence of a release. The concentrations likely represent naturally occurring
concentrations of arsenic at the site. Table 2 summarizes the findings of the soil analyses.
Investigational derived waste was properly placed into DOT approved 55-gallon drums and
temporarily stored near the southern property boundary of the Brownfields Property. The contents
of the drums will be properly disposed.
Please note, on October 30, 2019 it came to the attention of the PD that the grading contractor moved
approximately 1,800 cubic yards of stockpiled soil located along the storm sewer right-of-way that
transects the Brownfields Property. The soil was transported to the receiving site as previously
proposed. The stockpiled soil was determined to not have originated from a grid previously identified
as exhibiting elevated concentrations of hexavalent chromium or methylene chloride. The grading
contractor and PD communicated concerning the incoming precipitation and the necessity that
stormwater preventative controls be constructed at the site. The grading contractor mistakenly
interpreted that the PD was authorizing movement of stockpiled soil from the Brownfields Property.
However, the PD was referring to the moving of soil stockpiled along Ikea Boulevard onto the
receiving site that is not part of the Brownfields Property. It was not the intent of the PD to authorize
the movement of soil from the Brownfields Property to the receiving site prior to receiving written
approval.
Please note, the grid sampling discussed above has been summarized in the Report of Limited Soil
Assessment - Grid Sampling dated November 4, 2019, approved by the NCBP in the November 1,
2019 Brownfields Soil Management Options. Approximately 32,000 cubic yards of soil from the
Brownfields Property have been excavated and transported to the receiving site. As discussed in the
Report of Limited Soil Assessment – Grid Sampling, field activities associated with the management of
the soil on the Brownfields Property have included:
Stripped approximately six inches off the entire site (total of 5,300 cubic yards) and buried the
topsoil and organics in the excavated pit along the northern property line. As of the date of
this report, approximately 3,300 cubic yards of topsoil and organics have been placed into the
excavation pit along the northern property line Approximately 2,000 cubic yards of topsoil
has been excavated and is currently located on the surface and awaiting deposition into the
excavation pits.
Transported the existing stockpile to the receiving site (approximately 2,100 cubic yards).
Excavated Grids 2 through 5, Grids 7 and 8, Grids 10 through 20, Grid 22, Grids 25 through
28, Grid 31, and Grids 33 and 34 to their predetermined cut depths not exceeding four feet bls
and the soil has been transported to the receiving site. Additionally, extended excavation of
Grids 2, 4, and 7 to a depth of nine feet and transported soil to receiving site (29,700 cubic
yards).

Excavated soil from Grid 1, Grid 6, and Grid 9 and place soil into Grids 2 through 4 and Grid
7 (2,400 cubic yards).
Excavated soil from Grid 21 and Grid 32 and placed it into the buffer along the northern
property line (880 cubic yards).
On November 8, 2019 Progress returned to the site to complete additional sampling on the
Brownfields Property. Specifically, soil samples were proposed to be collected from Grids 23, 24,
and 30, which were formerly located beneath a soil stockpile. The soil sampling completed as part
of this assessment was to determine whether an additional approximately 1,000 cubic yards of soil
from the Brownfields Property meets the criteria to be transported to the receiving site. The soil
borings were advanced using a decontaminated hand auger. The soil borings were advanced to
depths determined using the estimated cuts in the vicinity of the remaining grids. Specifically, soil
borings in Grid 23 were advanced to depths ranging from one to two and a half feet bls; soil
borings in Grid 24 were advanced to depths ranging from one to three and a half feet bls; and soil
borings in Grid 30 were advanced to depths ranging from one to one and a half feet bls. The
locations of the additional soil sampling grids are depicted on Figures 2 and 3.
Three distinct grids were marked in the field near the northwestern extent of the proposed cut. The
grids were measured to be approximately 80 feet by 80 feet. Progress advanced five soil borings in
Grid 24. Based on the proposed extent of cut, only three soil boring were advanced in Grids 23 and
30. The locations of the soil borings are depicted on Figure 3. In an effort to establish uniformity,
the soil borings in each grid were labeled in the same manner as the original grid sampling
methodologies. For Grid 24, the soil boring in the southwestern corner of the grid was labeled
“A”, the soil boring in the southeastern corner of the grid was labeled “B”, the soil boring in the
northeastern corner of the grid was labeled “C”, the soil boring in the northwestern corner of the
grid was labeled “D”, and the soil boring in the center of the grid was labeled “Center”. The four
corner soil borings were located 10 to 15 feet from the staked corner of each grid. For Grid 23,
Progress only collected soil samples from the locations identified as “B”, “C”, and center since the
“A” and “D” locations are located in areas of proposed fill. Additionally, for Grid 30, Progress
advanced three soil borings (labeled “A”, “B”, and “C” located equidistant from one another along
the southern boundary of the grid since the majority of the grid has been previously evaluated
during a previous assessment or lies outside the area of proposed disturbance. A representative
sample from each soil boring interval was placed into two separate pre-labeled plastic baggies.
Following adequate time one baggie from each sample interval was screened using a PID for the
presence of volatile organic vapors. Progress utilized a pre-calibrated MiniRae 3000 equipped with
a 10.6 eV Lamp. The PID was calibrated in the laboratory using isobutylene (100 parts per
million) prior to shipment to the field, utilizing a correction factor for chlorinated solvents. The
distinct soil samples from each sampling interval were composited into one soil sample for each
grid unit. The composite sample from each of the grid units represented a total of six to ten soil
samples from each grid. The second baggie of the sample which indicated the highest PID reading
was placed into laboratory containers for laboratory analysis. The results of the PID screening are
summarized in Table 1.
The composite samples were analyzed for SVOCs using EPA Method 8270, for Total RCRA
Metals using EPA Method 6020, and hexavalent chromium using EPA Method 7199. The soil
sample that exhibited the highest reading when screened with the PID from each grid was analyzed
for VOCs using EPA Method 8260.

The soil samples were placed into laboratory prepared containers and then into a cooler packed
with ice, a trip blank, a temperature blank, and delivered under chain-of-custody to a North
Carolina certified laboratory. QA/QC documentation was provided, and a duplicate soil sample
was collected (Grid 242). Progress requested a Level II Data Package from the laboratory.
Additionally, Progress requested that the laboratory report the results to the method detection limit.
The duplicate sample was analyzed using the aforementioned methods. The assessment activities
were completed per the Inactive Hazardous Sites Branch, Guidelines for Assessment and Cleanup
(October 2015).
Laboratory analysis of the remaining composite and discreet soil samples did not exhibit VOCs,
SVOCs, or Total RCRA Metals at concentrations that exceed the Protection of Groundwater PSRGs,
with the exception of arsenic. The concentrations of arsenic exceed the Residential Health Based
and/or Industrial/Commercial PSRGs. Progress does not consider the concentrations of arsenic
detected to represent evidence of a release. The concentrations likely represent naturally occurring
concentrations of arsenic at the site. Table 2 summarizes the findings of the soil analyses.
REDEVELOPEMENT ACTIVITIES
In July 2019 the site was grubbed, removing the trees and associated stumps so that the erosion
control measures could be installed per Mecklenburg County regulations. A small temporary
sediment pond was constructed near the southeastern corner of the site. The material removed to
excavate the retention pond remained on-site and was stockpiled in the northwestern corner.
In September 2019 the sanitary sewer was installed across the site from the northwest to southeast.
Only one grid that was encountered was determined not to meet the requirements for export. The
soil from that grid was stockpiled on site adjacent to the excavation and was used as backfill in the
same grid it was excavated from.
In December 2019 the mass grading for the Brownfields Project was completed. Specifically, the
grids determined to be suitable for export were exported to the adjacent off-site property owned
and controlled by the PD under different ownership than the Brownfields Property. The grids that
were determined to not meet the criteria for off-site disposal were used as fill material along the
northern property boundary or in adjacent or nearby grids that were excavated below the projected
cut depth to accommodate the soil from a grid exhibiting a concentration exceeding the applicable
standards.
Arco Murray, the contractor for the developer, was provided a copy of the approved Environmental
Management Plan (EMP) and was given specific instructions to make appropriate notifications if
evidence of suspected contamination was encountered during grading activities. Arco Murray was
further instructed that dirt from the Brownfields Property or the export site was not to leave the
site. A copy of the EMP was posted in the on-site trailer for review by each of the subcontractors
working on the site. The grading contractor who performed the mass grading site work (Blythe
Development) was also engaged by Arco Murray to perform storm drain installation and fine
grading for the Brownfields Property. Blythe Development was familiar with the processes and
procedures of the EMP.
