1.0 BACKGROUND INFORMATION
State Employees Credit Union (SECU) is developing property located northwest of the intersection of Monroe Road and Shade Valley Road in Charlotte, Mecklenburg County, NC. The
location of the site is as shown in Figure 1. The site consists of an approximate 1.798-acre lot with PIN Number 16105222. The parcel outline is shown on Figure 2. The parcel is owned by State Employees Credit Union (SECU).
1.1 Site History
Based on prior Phase I ESAs performed on the site and surroundings sites, it appears that the site was developed at least back to 1938 with a filling (gasoline) station. Sometime between 1938
and 1943, the site was further developed with a dry-cleaners and portions of the Woonsocket Spinning factory. The site generally remained unchanged until 2006, when the Woonsocket Spinning factory and the dry-cleaning building were razed from the site. The fueling station was
then razed from the site in 2008. From 2009 to 2019, the site had been vacant.
1.2 Brownfields Assessment
Modulus performed a Brownfields Assessment of the Subject Site dated February 4, 2019. Based upon the results of that assessment, it was determined that the calculated groundwater to indoor air risk, along with the soil gas to indoor air risk both exceeded acceptable criteria. Therefore, vapor mitigation for the proposed building was determined to be warranted.
1.3 Vapor Intrusion Mitigation System
The construction consisted of a 1-story credit union branch, approximately 8,500 square feet in
plan size, along with a 1-story "teller outpost" building approximately 850 square feet in plan size. The buildings are of similar construction on a combination of strip and column footings with a slab-on grade.
Modulus prepared a Vapor Intrusion Mitigation System Design (Revision 4) dated April 29, 2020, specific to the proposed construction. The system included the installation of a vapor gas barrier,
a sub-slab vapor-vent gas collection system, and vent risers that run from the sub-slab region to the rooftop, connecting the vapor-vent gas collection system to the rooftop emission stack. As there were two buildings (main branch and drive-through outpost) constructed on the site, each building was fitted with a stand-alone mitigation system. Plan Views of the systems are shown as Figure 3 for the main structure and Figure 4 for the outpost structure.

2.0 SCOPE OF WORK
As part of the Vapor Intrusion Mitigation System Design, post construction / preoccupancy system testing was required for the systems prior to occupancy with the objective to document that the areas below the slab have been effectively influenced by the current piping network and that
occupants would not be exposed to unacceptable concentrations of contaminants. As part of the Vapor Intrusion Mitigation System Design, vapor pins were placed at locations
remotely distant from where each suction point transitions to below the slab in addition to locations near each suction point and associated horizontal piping. Seven vapor pins (VP-1 through VP-7) were installed in the main structure and two vapor pins (VP-8 and VP-9) were installed in the
outpost building, as indicated on Figures 3 and 4, respectively. Sub-slab monitoring was conducted once the core and shells were complete by sampling each of
the vapor pins with summa cannisters. In addition, one summa canister was also be placed inside each building to evaluate the post construction / preoccupancy Indoor Air Quality of each of the structures.

3.0 FIELD PROCEDURES
Field sampling was performed on Saturday November 20, 2021, while both structures were
vacant, closed and the HVAC operating.
3.1 Sub-slab Soil Vapor Sampling
The procedure for sampling sub-slab soil vapor was as follows: • All sub-slab soil vapor sampling was performed in accordance with NCDWM Vapor
Intrusion Guidance dated March 2018 and associated referenced documents.
• Leak testing was performed utilizing a helium tracer gas to detect leakage of ambient air into the soil vapor sample. A shroud was placed over the sample probe into which the tracer gas is introduced prior to sampling. Air was drawn from the sample zone and analyzed for the presence of tracer gas using a direct reading monitor.
• Prior to attaching the sample container, each vapor pin was purged by drawing 3.0 volumes through the probe and sampling train utilizing a disposable syringe. The probe was purged using a maximum purge rate of 100-ml per minute.
• Stainless steel canisters were fitted with flow rate regulators at a maximum of 100 milliliters per minute, which corresponds to a sample time of ten minutes for 1-Liter canister.
• Time and summa cannister pressure readings were recorded prior to and following sampling activities. Summa cannister pressure readings were not allowed to reach a pressure of “0” in the field. The laboratory recorded and reported the pressure of the
cannister upon receipt.
The sub-slab soil vapor samples were placed in and transported in sealed containers to Waypoint Analytical laboratory in Charlotte, NC for analysis. Samples were shipped with proper chain of custody forms, analyses request forms and sample seals.
3.2 Indoor Air Sampling
The procedure for sampling indoor air vapor was as follows:

• All indoor air vapor sampling was performed in accordance with NCDWM Vapor Intrusion Guidance dated March 2018 and associated referenced documents.

• Stainless steel canisters were fitted with flow rate regulators at a rate of approximately 2.1 milliliters per minute, which corresponds to a sample time of approximately 8 hours for 1-
Liter canister.
• Time and summa cannister pressure readings were recorded prior to and following sampling activities. Summa cannister pressure readings were not allowed to reach a pressure of “0” in the field. The laboratory recorded and reported the pressure of the cannister upon receipt.
The soil vapor samples were placed in and transported in sealed containers to Waypoint Analytical laboratory in Charlotte, NC for analysis. Samples were shipped with proper chain of
custody forms, analyses request forms and sample seals.

4.0 ANALYTICAL
The analytical methods used to test for the parameters discussed were the most recent versions of the analytical methods stated below. For SW-846 Methods, the latest edition of SW-846,
including any subsequent updates which have been incorporated into the edition, were used. Sampling was planned so that required holding times for analytical methods were met. All samples were analyzed per Appendix A.7 of the Inactive Hazardous Sites Program’s Guidelines
for Assessment and Cleanup dated October 2015
4.1 Vapor Samples
Sub-slab Soil Vapor and Indoor Air Samples were analyzed by the following methods:
• Volatile Organic Compounds (VOCs) - EPA Compendium Method TO-15 ((EPA/625/R-96/010b)
The laboratory performing the soil vapor analyses is a NVLAP or other nationally accredited laboratory. The laboratory reported estimated values down to the MDL (including J flags) and made every attempt to have Reporting Limits meet the applicable standards.

6.0 CONCLUSIONS
Based upon the data obtained from the Post Construction / Preoccupancy System Testing, it appears that that the proposed design is effective at mitigating the potential for vapor intrusion at the property and protecting public health as a passive system. It is the opinion of the engineer of record that the system as installed will be fully protective of public health. According to the DEQ Risk Calculator, a sub-slab soil vapor concentration of chloroform produces a calculated indoor air concentration of 0.0155 ug/m3. As chloroform is a has common use in building materials, it is highly possible that the detected concentration of chloroform in Indoor Air was from a building source and not from a subgrade source.
Modulus requests that DEQ Brownfields review this information and provide conditional occupancy consideration as per standard VI provisions. Modulus recommends that post
occupancy sub-slab vapor and indoor air sampling be repeated and re-evaluated in three months.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic risk
or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.
