PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, City of Charlotte, requests approval to
discharge treated GW from a site formally used by Mecklenburg
County and'NCDOT as a highway maintenance facility. Various tanks
containinggasoline, kerosene, fuel 'oil and waste oil were
located at the site and, upon removal, were found to have
contaminated the underlying GW table. All highway maintenance
activity was ceased several years ago, and the site has since
been occupied by an Office' enter.
The proposed treatment facilities are to be located in an
undergroundvault at the request of the Office Center since the
contaminated area is adjacent to the Office Center entrance. The
discharge will exit the storm sewer 't 100 feet prior to entering
Sugar Creek.
Pending technical review and approval by PEE, it is
recommended that a GP be issued for this facility, provided
toxicity is found not to be a problem.
