Dear Mr. Atkinson:
Please find attached the soil gas and free -product assessment report performed at the Carolina Coach
Company (aka, the Greyhound Bus Maintenance Facility) site in downtown Raleigh.
Vapor intrusion sub -slab soil gas sampling was conducted on October 23 through 25 and the free product
assessment was completed on October 29. The assessment tasks were done in accordance with the DEQ-
approved work plan.
The soil gas test results indicated low levels of TCE along the western side of the property. The TCE by
itself may not pose an unacceptable risk. We also measured some petroleum constituents elsewhere that
similarly may not pose an unacceptable VI risk. We did, however, have high soil gas detection limits that
impacted our ability to be definitive about the possible risks.
No free product was found in groundwater in the piezometer well we checked.
With this assessment work completed, we'd like to discuss the VI soil gas test results and the possible need
for VIMS. We'd also like to begin drafting the Brownfields Agreement with you.
If you have any questions or need additional information, please feel free to contact me at [phone].
Sincerely,

VI Testing - We conducted vapor intrusion (VI) soil gas sampling at the former Greyhound Bus Maintenance
Facility property (Drawing 1 Site Map, Drawing 2 Topo Map and Drawing 3 Site Features Map) on October 23,
24 and 25, 2019. One sub -slab soil gas sample was collected from beneath each of the planned 12 residential
condominium buildings. The development masterplan is provided in Drawing 4.
Samples were analyzed by USEPA Method TO-15. Only trichloroethylene (TCE) at one location, SG-5 (Drawing
5), was detected above its residential soil gas screening level (RSGSL). Otherwise, no other detected analytes were
measured above their respective RSGSLs. However, due to unavoidably sample dilution, certain results reported as
being non -detect (ND) had high reporting limits above RSGSLs.
Most importantly, at location SG-8, heptane, hexane, cyclohexane and acetone were well below their RSGSLs but
nevertheless at high enough levels where the laboratory had to dilute the samples. This resulted in the high detection
reporting limits for 12 ND analytes (one was TCE) to be above their respective RSGSLs. In addition, soil gas
samples from locations SG-5, SG-9 and SG-12 reported ND for 1,2-dibromoethane and 1, 1, 1 -trichloroethane, but
the detection reporting limit for the two analytes were above their RSGSLs.
Using DEQ's Risk Calculator for TCE alone (the only detected analyte above its RSGSL) indicated minimal VI
carcinogenic risk was <1x10-4 and the hazard quotient was <1, the TCE measured at SG-5, in and of itself, would
not pose an unacceptable risk.
Next, to be more conservative, we ran the Risk Calculator for TCE and the highest concentration of all the other
detected analytes. This also indicated no unacceptable risk — the cumulative cancer risk was 1.6 x 10-5 and the
cumulative non -carcinogenic hazard quotient was 0.9. Although we recognize although these calculated risks are
close to DEQ's target level for noncarcinogens
Finally, when the high detection limits were entered into the Risk Calculator for the non -detected analytes at SG-8,
along with the TCE measured in SG-5 and all other detected analytes, the calculated cancer risk increased to 8.9 x
10' and cumulative hazard quotient was 17. However, we believe that including elevated reporting limits for ND
analytes in the Risk Calculator greatly overestimates the risks. A total of 10 of the 12 ND analytes in SG-8
(everything but TCE and vinyl chloride) were consistently not detected in the other soil vapor samples, and their
reporting limits were low and below RSGSLs. Plus, many of the analytes driving the risk are obscure compounds
and not contaminants of concern we would expect to find at the site.
Buildings within a 100-foot vapor inclusion zone of SG-5 and GG-8 are shown in Drawing 6. A link to an online
album with Photographs is provided in Appendix A. The NCDWM Residential Vapor Intrusion Screening Levels
Table (February 2018) is provided in Appendix B, the Laboratory Report and Chain of Custody Forms are in

provided that present the findings onto overlays of the prior soil investigation (Drawing 7), groundwater
investigation (Drawing 8), and the pre-remediation 1998 site map ((Drawing 9).
Free Product Testing - On October 28, 2019, we checked an existing piezometer well located on the southern side
of the property for free -product petroleum and found none.

SM Raleigh, LLC plans to construct condominiums at the former Carolina Coach Company site (aka., Greyhound
Bus Maintenance Facility) located at 1201 & 1208 S. Blount Street in Raleigh. Drawings 1 and 2 depict the site
location and topographic site plan, respectively. The 3.86-acre property consists of two parcels bounded by Bragg
St to the north, South Person St to the east, Branch St to the south, and South Blount St to the west.
On September 10, 2018 the site was deemed eligible to participate in the Brownfields Program and assigned NCBP
Project No. 22053-18-092. Additional background information was provided by Aptus in the October 16, 2019
work plan, including a summary of extensive remediation performed in 2018 for Greyhound by Strata
Environmental Services, Inc. and HEPACO, LLC. Drawing 3 includes a site features map with prior building
footprints, underground storage tanks (USTs), and a delineation of the excavation area from 2018 remedial action.
The proposed development includes building 12 condominium buildings and associated driveways that will
encompass nearly the entire property (the proposed masterplan is shown in Drawing 4.) While the site has been
remediated and no USTs remain onsite, soil gas sampling was conducted to assess whether unacceptable VI risks
exist and if mitigation may be needed. Additionally, at the request of NCBP, a well was sampled to determine
whether petroleum free product remained at the southern property boundary. A work plan was submitted for the
assessment activities on October 16', which was approved the next day, October 17'.
3. FIELD ACTIVITIES
3.1 Soil Gas Sampling
On October 23', the soil gas sampling locations were identified using coordinates from the sampling locations
drawing, aerial imagery and a measuring wheel. The locations were marked with painter's tape and stakes. Of the
12 sampling locations corresponding to proposed building footprints, all but one was beneath existing slab
foundations or asphalt and samples that could be collected as sub -slab probe points. At one sampling location
(Sample ID SG -I I at the Strata excavation area), stone/fill material was encountered that prevented placing a
sampling probe. Approval was obtained in the field via email from NCBP to relocate the sampling point to the
nearest slab, which was 22 feet due east of the original location. Although relocated, this location remained within
the proposed building footprint.
After the sampling locations were marked, RDHEC installed Vapor Pins at each sub -slab point per the approved work
plan, as follows:
• A hammer drill was used to bore 5/8-inch diameter holes through the slab to the soil beneath (approximately
16-inch depth each).
• At each location, the thickness of the concrete slab/pavement and underlying soil depths/characteristics
were noted (Table 1).
• Vapor Pins® fitted with silicone sleeves were secured into each boring.
• Probe placement continued for each of the 12 Vapor Pin locations, allowing them to equilibrate for at least
1 to 2 hours while the remaining probes were placed.
When the probe installation work was completed, the locations were left to equilibrate overnight prior to sampling. The
sub -slab sampling points and free product well location were overlaid onto a 2018 aerial view of the site
(representative of current site conditions) in Drawing 5. The locations are also shown relative to the building layouts
from the proposed masterplan of the site in Drawing 6.

Soil Gas and Free Product Assessment Report Page 4
Soil gas sampling was conducted on October 24th and 25th. On the first day of sampling, Reina Clark and Aditi
Chakravarty from the DEQ observed the assessment work. A summary of the soil gas sampling parameters (e.g.,
canister information, shut-in test, pre -/post -leak check details) is provided in Table 2.
3.2 Petroleum Free Product Evaluation
On October 24t'', a piezometer monitoring well, PZ-02, was found near the south property line just outside the fence
in a driveway entrance to the site along Branch Street. The tag inside the well cover indicated it was a 2-inch
diameter, 25-foot deep well (casing depth 15 feet, screen depth 15 to 25 feet) that was installed by Terra Sonic
International from Marietta, OH, on July 16, 2015.
This well was within a few feet of where we had planned to install a new temporary well to check for free product.
Therefore, instead of installing a new well, we decided to use the existing piezometer instead. Ms. Clarke from the
DEQ concurred with this planned approach.
On October 28', Tom Proctor, Proctor Environmental Services, Inc. (PES), visited the site to check piezometer PZ-
02 for free -product petroleum (see Drawings 5 through 9). Upon removing the well's protective cover and locking
cap, a new, disposable bailer was slowly lowered approximately 15 feet into the well until groundwater was
encountered. The bailer was then lowered another 18" and retrieved to the surface where it was inspected for the
presence of free product.
No free -phase petroleum product was noted floating on the water in the bailer and the water in the bailer did not
exhibit petroleum odors.
4. ASSESSMENT RESULTS
4.1 Soil Gas Results
The soil gas samples were analyzed by EPA Method TO-15. The laboratory results for the soil gas analyses are
summarized in Table 3.
Acetone and ethanol, common lab contaminants, were measured in all samples. Petroleum constituents were
detected in several samples with the highest levels found in SG-8, located at the center eastern edge of the site. Only
one detected analyte, trichloroethylene (TCE) at only location SG-5, exceeded its RSGSL, At location SG-5, the
TCE concentration was 45 ug/m3 and the RSGSL is 14 ug/m3. Otherwise there were no other detected analytes in
any samples above their respective RSGSLs.
For samples SG-5, SG-8, SG-9 and SG-12, due to unavoidably sample dilution, certain results reported by the
laboratory as being non -detect (ND) had reporting limits above RSGSLs. Most importantly, at location SG-8,
heptane, hexane, cyclohexane and acetone were well below their RSGSLs but nevertheless at high enough levels
that forced the laboratory to highly dilute the sample. This resulted in the reporting limits for 12 ND analytes (one
was TCE) in SG-8 to be above their respective RSGSLs. In addition, soil gas samples SG-5, SG-9 and SG-12
reported ND for 1,2-dibromoethane and 1, 1, 1 -trichloroethane, but the reporting detection limit for the two analytes
were above their RSGSLs.
We discussed the results with the Con -Test lab manager, Tod Kopyscinski. He said SG-8 had a 300X dilution due
to matrix interferences due to high levels of petroleum hydrocarbons and they were unable to lower the reported
detection limits. The chromatograms of SG-9 and 10 had a 20X dilution. Mr. Kopyscinski indicated that retesting
at these locations would likely have the same interferences and not result in being able to have lowered reporting

detection limits.
4.2 VI Risk Calculator
March 6, 2020
Page 5
To evaluate possible risks, we considered three scenarios, First, only the TCE concentration at SG-5 was inputted
in the DEQ Risk Calculator to determine the Resident Soil Gas to Indoor Air risk. The cancer risk solely from TCE
was 2.8 x 10' and the non -carcinogenic hazard quotient was 0.65. This is less than the target carcinogenic risk level
of lx10-4 and hazard quotient of 1. Therefore, considering just the TCE at SG-5, no unacceptable VI risk was
indicated.
Next, to be more conservative, the potential resident VI risk was assessed using the Risk Calculator for TCE and
the highest concentration of all the other detected analytes. The cumulative cancer risk was 1.6 x 10-5 and the
cumulative non -carcinogenic hazard was 0.9, also below acceptable risk levels.
Finally, when the high detection limits were entered into the Risk Calculator for the non -detected analytes at SG-
8, along with the TCE and vinyl chloride measured in SG-5, the calculated cancer risk increased to 4.4 x 10-4 and
cumulative hazard quotient was 9.3. Under this scenario, the calculated values exceed allowable risk levels and a
VIMS could be required for buildings within a 100-foot vapor inclusion zone (also see Drawing 6).
However, we believe that including elevated reporting detection limits for ND analytes in the Risk Calculator
greatly overestimates the true risks. Of note, 10 of the 12 ND analytes in SG-8 (everything but TCE and vinyl
chloride) were consistently not detected in the other soil vapor samples, and their reporting limits were low and
below RSGSLs. Plus, many of the analytes driving the risk are obscure compounds and not contaminants of
concern.
5. CONCLUSIONS AND RECOMMENDATIONS
VI sub -slab soil gas sampling was conducted on October 23 through 25 and the free product assessment was
completed on October 29. The assessment was done in accordance with the DEQ-approved work plan.
The soil gas test results indicated low levels of TCE along the west central side of the property at sampling location
SG-5, but in no other sampling locations. Previous assessment work in October 2013 in the vicinity of SG-5 also
reported low-level TCE in soil (GP-13, 0.022 mg/kg) and groundwater. (MW-4, 9.6 ug/L). Petroleum constituents
were measured in soil gas elsewhere, including at relatively high levels in SG-8, but below RSGSLs. For samples
SG-5, SG-8, SG-9 and SG-12, due to unavoidably high ample dilution, certain results had reporting detection limits
above RSGSLs.
Our evaluation of potential VI risks indicated the TCE, by itself, would likely not pose an unacceptable risk.
Similarly, the cumulative VI risk posed by all the detected analytes would likely not pose an unacceptable risk,
although the calculated risks were close to DEQ's target level for noncarcinogens. Finally, when the high reported
detection limits for the non -detected analytes are considered, the calculated VI risks are well above the DEQ's target
levels. But we believe this final risk assessment scenario is conservative and greatly overestimates the VI risk.
Based on the VI assessment results and our evaluation of risks, we recommend further discussions with the DEQ
regarding the possible VI risks and the potential need for either passive or active VI mitigation for the condominium
development.
Lastly, based on the October 28, 2019 sampling, there were no free -phase petroleum product concerns noted at the
southern property line. No further action is recommended with respect to possible free -phase petroleum product in
groundwater.

NOTES:
1. NO = Not detected above the lab reporting limits shown in parenthesis.
2. NT= Not tested.
3. -= No IHSB Residential or Non -Residential screening limits limits.
4. Yellow Shaded values exceed the IHSB Residential Soil -Gas Screening Limits.
5. IHSB Residential screening limits displayed for Xylenes are for the summation of all isomers and not for the individual isomer. Cells for individual isomers might not be in italics, and/or shaded when the summation (total amount of all
Isomers) exceeds the limits for these parameters. User discretion is advised when interpreting these results.

NOTES:
1. ND = Not detected above the lab reporting limits shown in parenthesis.
2. NT = Not tested.
3. -= No IHSB Residential or Non -Residential screening limits limits.
4. Yellow Shaded values exceed the IHSB Residential Soil -Gas Screening Limits.
5. IHSB Residential screening limits displayed for Xylenes are for the summation of all isomers and not for the individual isomer. Cells for individual isomers might not be in italics, and/or shaded when the summation (total amount of all
isomers) exceeds the limits for these parameters. User discretion is advised when interpreting these results.
