Subject: Additional Site Assessment Activities
Double Oaks
2623 Double Oaks Road
Charlotte, Mecklenburg County
Brownfields Project Number 11037-07-60

Dear Mr. Griffin
The North Carolina Department of Environmental and Natural Resources (DENR) has
reviewed the currently available site information for the above referenced site and determined
that data gaps have been identified. Additional assessment activities, as outlined below, are
required to assist in making risk management decisions for inclusion in the brownfields
agreement (BFA). During the evaluation process the following sources were utilized:
brownfields property application (BPA) and discussions during our site meeting on November
17, 2008.

The following assessment items need to be addressed to determine that the site is safe for
its intended reuse, which is mixed use with residential, commercial, school, daycare, recreational
and open space.

• General: The most recent Inactive Hazardous Sites Program Guidelines for Assessment
and Cleanup (http://www.wastenotnc.org/sfhome/stateleadguidance.pdf ) should be followed,
which in turn relies upon EPA's Environmental Investigations Standard Operating Procedures
and Quality Assurance Manual (a .pdf version is available on their website at
http://www.epa.gov/region4/sesd/eisopqam/eisopqam.html). Request Level 2 QA/QC data
packages from a N.C. certified environmental laboratory. Submit a work plan for review prior to
conducting field work for approval by DENR to ensure all aspects of the requirements are
covered.

• Soil-Gas: collect soil-gas samples around sample location former boring (DO-5A) from
TEG Reports and boring location 2A/B from The Environmental Group of the Carolinas, Inc.
(TEG )Reports.

• Laboratory Analyses: Submit samples to a NC-certified laboratory. Analyze all soil-gas
samples by TO-15 Method to include volatile organic compounds and semi volatile compounds.
Ensure laboratory method detection limits are below applicable standards. Provide complete
original laboratory reports and associated laboratory QA/QC documentation in the final report to
DENR.

• Adjacent Landfill: Provide additional background information on the adjacent landfill,
such as when did it operated, type of landfill material accepted and what has been seen on the
site, when was it closed, ongoing assessment or monitoring, and permit information. Based on
the initial site work provided in the June 21, 2007 Report of Methane Monitoring prepared by
TEG additional assessment will likely be required.

• Report and Figures: Submit an assessment report with a description of field activities,
tabulated data (including historical data), the laboratory data packet, and information requested
in above bullets. Provide concentration map(s) for contaminants detected above applicable
standards. Provide summary analytical table for contaminate detected by the laboratory versus
the state standard and include historical data, if available.

If you have any questions regarding this letter or the brownfields process, please feel free
to contact me at 704/661-0330, or via e-mail at [e-mail]

Sincerely,

Carolyn F. Minnich
