Dear Mr. Tucker:
The North Carolina Department of Environmental Quality (DEQ), Brownfields Program has
reviewed the documents submitted with the Brownfields Property Application for the Bookers
Garage Site at the above referenced address in Charlotte, Mecklenburg County. The following is
a summary of the reports reviewed:
Report Title
Prepared by
Date of Report
Phase I ESA
ECS Southeast, LLP
October 21, 2019
Report of Limited Soil and Groundwater
ECS Southeast, LLP
November 21, 2019
Based on our review of these documents, data gaps were identified. Additional assessment
activities, as outlined below, are required to assist in making risk management decisions for
inclusion in the Brownfields Agreement (BFA). The following areas of the site will require
additional assessment. Prior to conducting field activities, a work plan should be submitted to
DEQ for review and approval. The work plan should include a description of the sampling and
analytical methods to be utilized as outlined in the DEQ Brownfields Environmental Site
Assessment Work Plan Checklist (November 2018) and a map depicting the proposed sample
locations. The most recent Inactive Hazardous Sites Program Guidelines for Assessment and
Cleanup should be followed (http://portal.ncdenr.org/web/wm/sf/ihs/ihsguide) Request Level 2
QA/QC data packages from a N.C. certified environmental laboratory. Collect one duplicate
sample per media per method per 5% of samples.

1) Groundwater Sampling: Install two temporary monitoring wells at the following locations:
- Northeast and downgradient of the former automotive service garage; and
- In the eastern portion of the Brownfields Property.
Collect a sample from each temporary monitoring well for analysis of volatile organic
compounds (VOCs) by EPA Method 8260, semi-VOCs (SVOCs) by EPA Method 8270, and
Resource Conservation and Recovery Act (RCRA) Metals by EPA Method 6020. Wells
should be appropriately developed and parameters allowed to stabilize prior to sample
collection.
2) Soil Sampling
- Collect one composite soil boring in the eastern portion of the Site consisting of three
to five surficial (0-2 ft interval) soil points. The composite sample shall be analyzed
for SVOCs by EPA Method 8270 and RCRA Metals plus hexavalent chromium by
EPA Method 6020/7199. Collect one grab sample for analysis of VOCs by EPA
Method 8260 from the soil boring exhibiting the highest evidence of impact based on
visual, olfactory, and PID observations. Should evidence of impact be identified at the
base of the soil borings, extend the borings to a total of 5ft bgs and collect a sample at
the two -foot depth interval with the highest evidence of impacts.
- Collect one soil sample from the two -foot depth interval within each temporary
monitoring well with the highest evidence of impact for analysis of VOCs by EPA
Method 8260, SVOCs by EPA Method 8270, and RCRA Metals plus hexavalent
chromium by EPA Method 6020/7199.
3) Utilize Ground Penetrating Radar (GPR) to evaluate for the presence of underground
storage tanks (USTs) around current structures. Include in the work plan the sampling
protocol should a UST be identified. Generally, UST sampling shall be conducted in
accordance NC DEQ UST Section guidance.
4) Soil Gas: Based on the history of the property being used for an automotive garage and the
intention of residential redevelopment, there is the potential for vapor intrusion to
negatively impact indoor air. Collect a total of 6 soil gas samples within the footprint of
the planned buildings at the approximate depth of the basement foundation for analysis of
VOCs by EPA method TO-15. Include a helium leak check prior to sampling and ensure
that laboratory method detection limits are below applicable standards.
5) Receptor Survey: Complete the enclosed Brownfields Property receptor survey and include
as an attachment to the Additional Assessment Report.
Report and Figures: Upon receipt of analytical data, submit a summary report with a description
of field activities, tabulated data in comparison to applicable screening levels, and the laboratory
data packet with applicable QA/QC documentation, provide a site plan with monitoring well

locations, locations of sample points, and current site structures. Provide concentration map(s) for
contaminants detected above applicable standards. Include a detailed description of current
operations since the Brownfields Property application was submitted. Please note, all sample
points may need to be included on the future Brownfields plat. DEQ recommends having sample
locations surveyed at the time of collection for use in preparation of the Brownfields plat.
Please provide the Work Plan for additional assessment activities as soon as you are able. If you
have questions about this correspondence or require additional information, please feel free to
contact me by phone at 704-223-6549 or by email at jordan.thompsongncdenngov.
Sincerely,
Jordan Thompson
