Brownfields Project No. 23055-19-060
H&H Job No. PDP-001

Dear Carolyn:

On behalf of 3615 Tryclan, LP (Prospective Developer or PD), Hart & Hickman, PC (H&H) has
prepared this vapor intrusion mitigation system (VIMS) installation data summary to document
pre-occupancy sampling recently completed at the Battery and Ignition Distribution Brownfields
property (Brownfields Project No. 23055-19-060) located at 3615 Tryclan Drive in Charlotte,
Mecklenburg County, North Carolina (Site). Redevelopment of the Site includes construction of
a multi-family apartment building, a parking deck, and paved vehicle access roads. A Site
location map is included as Figure 1, and a Site map is provided as Figure 2.

In September 2023, pre-occupancy VIMS efficacy sampling was completed for the lounge area
(Area A2) and included collection of one sub-slab soil gas sample and one duplicate sub-slab soil
gas sample. Sub-slab soil gas sampling was completed in general accordance with the North
Carolina Department of Environmental Quality (DEQ) approved Vapor Intrusion Mitigation Plan
(VIMP) dated September 3, 2021. A tabular summary of sub-slab soil gas analytical results and
hypothetical worst-case risk calculations is included as Table 1. A copy of the as-built VIMS
design sheet depicting the sample location (Area A2) is provided as Appendix A, a copy of the
laboratory analytical report is provided as Appendix B, and copies of the DEQ risk calculators
are provided as Appendix C. A brief summary of the sampling results is provided below.

 Results of the sub-slab soil gas sample and duplicate sample collected in Area A2
identified several compounds at concentrations above the laboratory method detection
limits, but no compounds were detected at concentrations above the DEQ Vapor
Intrusion Sub-Slab and Exterior Soil Gas Screening Levels (SGSLs).

2) DEQ Non-Residential SGSLs dated July 2023.
3) DEQ Cumulative Risk Calculator dated July 2023.
Only constituents detected in at least one sample are shown in the table above.
Compound concentrations and SGSLs are reported in micrograms per cubic meter (µg/m3).
Compound concentrations are reported to the laboratory method detection limits.
Analytical method follows parameter in parenthesis.
NE = not established; B = analyte detected in laboratory method blank
J = Compound was detected above laboratory method detection limits but below laboratory reporting limits,
resulting in a laboratory estimated concentration.

Client Project Description: PDP.001
Waypoint Analytical, LLC (Charlotte) received sample(s) on 9/11/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager

Output Form
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Since these chemicals do not pose a vapor intrusion risk,
no risk values are calculated for these chemicals.
