1:INTRODUCTION
The 6.9i acre subject property is located along the northern side of Rotary Drive,
approximately 1,400 feet west of its intersection with Starita Road in Charlotte,North Carolina.
The property is comprised of Mecklenburg County Tax Parcel ID No.04501312 and has a
physical address of 3201 Rotary Drive.An existing single—story building occupies the central
portion of the site.The building (approximately 46,800 square feet)was reportedly constructed
in 1968 and is currently in use as office and warehouse space.The portion of the property
surrounding the existing building generally consists of paved parking areas,landscaped area,
and grass lawns.However,the northern portion of the site (approximately 2 acres)is wooded
land.
Background:The property was owned by Covington Diesel from 1968 until 1985.
Covington Diesel operated the site as an automotive engine repair facility and truck garage.
In 1985,SPG Prints purchased the site from Covington Diesel.SPG Prints also owned the
western adjoining property (3001 Boxmeer Drive)and operated both facilities as a single
campus.The 3001 Boxmeer Drive property is also subject to a Brownfields Agreement
(19051—15—060).
Primary production work by SPG Prints on the subject site was production of nickel sleeves
from the operation of nickel-plating baths.Other key activities included production of
mandrels and rollers out of copper and chromium plating baths.In addition,SEAMEX
polymer production that was initially performed at the adjoining 3001 Boxmeer Drive
property was moved to the subject site.The polymer process involved the use of
tetrachloroethylene (PCB)and trichloroethylene (TCE).SEAMEX polymer production
reportedly ceased in 1990.
It is our understanding that the site was placed under a Ready-for-Reuse Brownfields
Agreement in October of 2016.
Soil Imgact:Previous assessments at the property identified minor impacts from metals.
However,only arsenic was detected at concentrations exceeding North Carolina remediation
goals.Arsenic detections on the site ranged from 3 to 10 mg/kg,but background samples
exhibited concentrations of 4.1 and 4.6 mg/kg.With no known sources of arsenic from site
operations,the on-site arsenic was deemed to be naturally occurring.
Groundwater Imgact:Previous assessments identified chlorinated solvent contamination in
the shallow groundwater across the central portion of the site.Specifically,PCE was
detected at sample locations GP-l,GP-3,and MW-lOl (see Figure 2 in Appendix I)at
concentrations exceeding North Carolina Groundwater (2L)Standards.In addition,TCE was
detected at GP-3 at a concentration exceeding its 2L Standard.The concentrations of PCB
and TCE detected at location GP-3 also exceeded their respective non-residential vapor
intrusion screening levels.Although chlorinated solvent contaminants were also detected in

the groundwater at the western adjoining 3001 Boxmeer Drive property,the assessments
conducted to date suggest that the plumes are separate.Therefore,it is presumed that the
chlorinated solvent contamination at the subject property is the result of historic site
operations.
Potential Vapor Intrusion:Geoscience previously installed temporary sub—slab vapor
monitoring points (V-1 through V-5 and V101 through V103)at eight (8)locations in the
building.The approximate locations of the sample points are indicated on Figure 3 in
Appendix 1.
Analysis of sub—slab vapor samples collected at these locations collected in December 2013
and October 2015 revealed the presence of several VOCs in the soil gas beneath the building.
Specifically,PCE was detected at all sample locations during both sampling events,with the
highest concentration being detected at sample point V—5.While the PCB concentration at
V—5 was below the non—residential vapor intrusion screening level during the 2013 sampling
event,it was detected at a concentration of 3,590 ug/m3 in 2015,which slightly exceeds its
3,500 pig/m3 non—residential vapor intrusion screening level.No other compounds were
detected at concentrations that exceed the current (February 2018)soil gas concentration
screening levels for non—residential properties.
In order to further assess vapor intrusion,two (2)rounds of indoor air samples were collected
close to the location of sample V-5.These sampling events demonstrated that PCE
concentrations inside that portion of the building did not exceed non-residential indoor air
screening levels.Tables 2 and 3 in Appendix I summarize the previous sub-slab vapor and
ambient air sampling results,respectively.
2:SAMPLING METHODOLOGY
Geoscience mobilized to the site on September 15,2020,to install seven (7)temporary sub-
slab vapor monitoring points inside the existing building.The temporary sub-slab vapor
monitoring points were installed at locations V-101,V-102,V-103,V-1,V-3,V-4,and V-5.
We opted not to resample location V-2 as that location is close to V-103,and the PCB
concentration at V-103 was higher than at V-2 during the previous sampling events.The
temporary monitoring points were created by grouting 1%:inch diameter Teflon tubing into a
3A inch hole drilled through the building floor slab.The tubing was placed such that the
bottom end of the sample tube was approximately 6 inches below the top of the floor slab.
The sub-slab vapor samples were collected between September 18 and 22,2020.Each
sample was collected using a 6 Liter Summa canister fitted with a flow control orifice
pre-calibrated to collect the sample at a rate less than 200 ml/min.The canisters were
connected to the sample points via laboratory supplied purge manifolds.Information
regarding the manifold construction is included in Appendix III.

At each location,the sample canister,monitoring point,and purge manifold were enclosed
within a plastic shroud.Throughout the leak test and sample collection process,an
approximately 40%helium atmosphere was be maintained within the shroud.Once the
helium concentration within the shroud had been established,more than three (3)volumes of
the sampling train were purged,using a syringe,from the manifold at a rate not to exceed 70
ml/min.Following this purge,a Dielectric MGD 2002 Leak Detector was be used to monitor
the concentration of helium in gases being drawn through the sampling train.Once it was
established that helium concentrations measured in the sampling train were less than 5%0f
the shroud concentration,the sample was deemed to have passed the helium leak test.
Following the helium leak test,the valve connecting the purge manifold to the sample point
was closed,and the syringe was used to establish a vacuum in the portion of the sample train
between the valve and the canister.The vacuum level in the sample train was then monitored
for 2 minutes.When the vacuum level in the sample train held,the vacuum leak test was
considered to have been passed.
After the vacuum leak test had been passed,the valves were set such that sub—slab vapor was
pulled into the canister through the purge manifold and flow control orifice.Sample
collection was terminated when the vacuum gauge on the canister read a negative pressure of
5 inches of Hg.The full canisters were placed in laboratory—provided containers and
transported under appropriate chain-of-custody procedures to Pace Analytical for chemical
analysis.The collected samples were analyzed by EPA Method TO-15 for VOCs (full
analyte list)and for total helium content.Table l in Appendix 1 summarizes the information
collected during the leak tests and sample collection.Copies of the field notes are included
in Appendix III.
3:SAMPLE RESUL TS
The results of the sub-slab vapor sampling event are summarized on Table 2 in Appendix I.
In accordance with the NCDEQ guidelines,Geoscience has compared the results with non-
residential vapor intrusion screening levels established by the Division of Waste
Management.As shown on Table 2,during the recent sampling event,PCE was detected at
all seven (7)sample locations.The detected PCE concentrations ranged from 2.5 ug/m3
(V-l)to 4,160 ug/m3 (V-5).The PCE concentration at V-5 (4,160 ug/m3)exceeds its non-
residential vapor intrusion screening level of 3,500 ug/m3.However,none of the remaining
sample locations exhibited a screening level exceedance for PCE.
TCE was detected in the samples from V-4,V-5,and V-103 at concentrations ranging from
1.7 ug/m3 to 68.2 ug/m3.However,these concentrations do not exceed the TCE non-
residential vapor intrusion screening level of 180 ug/m3.None of the remaining degradation
products of PCB (cis-l,2-dichloroethylene,trans-l,2-dichloroethylene,1,1-dichloroethylene,
and vinyl chloride)were detected in the sub-slab vapor samples.

An assortment of other volatile organic compounds was detected in the sub—slab vapor
samples collected during this event.The compounds detected were consistent with the
previous sampling events.None of these compounds were detected at concentrations
exceeding non—residential screening levels.A copy of the laboratory test report is included in
Appendix II.
4:QA/QC
Geoscience collected one duplicate sample (V—104)during this sample event.The duplicate
sample was collected at location V—4 by connecting the V—4 and V—104 canisters together
with a tee fitting so that the samples were collected simultaneously.The duplicate sample
was analyzed by the same methods as the other collected soil gas samples.Review of the
sample results shows that the results of samples V—4 and V—104 do not significantly differ.
The laboratory did not detect helium in any of the samples (reporting limit of 0.74%He).
Given that the helium concentrations within the shrouds were kept at approximately 40%,the
helium concentrations measured in the samples are,at most,less than 1.8%of the shroud
concentrations.This is significantly less than the allowable 10%of the shroud concentration.
As such,the samples are assumed to not have suffered leaks in the sample train or at the
slab/monitoring point seal.
5:FINDINGS AND CONCLUSIONS
PCE has been detected in all sub-slab vapor samples collected to date beneath the building.
However,with the exception of the samples collected at V-5,the detected PCE
concentrations have been well below the 3,500 ug/m3 PCE vapor intrusion screening level for
non-residential properties.The concentrations measured at V-5 on October 15,2015,and
September 21,2020,exceed the non-residential PCE screening level by 90 ug/m3 and 660
ug/m3,respectively.
It is apparent that there is an area of higher PCE vapor concentrations beneath the floor slab
in the vicinity of V-5.However,the indoor air sampling events conducted in December 2015
and January 2016 suggest that the PCB concentrations beneath the floor slab at V-5 were
approximately 850 times higher than the PCB concentrations inside the building at that
location.Using that attenuation factor suggests that the indoor air PCE concentration near
V-5 would currently be approximately 5 ug/m3.This would be well below the non-residential
indoor air screening level of 35 ug/m3 established for PCE.Geoscience anticipates that the
NCBP will request additional indoor air sampling be conducted to verify the air quality inside the
building.

The TCE,PCE degradation products,and other volatile organic compound concentrations
detected to date in the sub—slab vapor samples collected beneath the building have been well
below their respective non—residential vapor intrusion screening levels.Based on these
results,we conclude it is unlikely that intrusion of these compounds from the subsurface into
the building will significantly impact the indoor air quality.
