Re: Notice of Violation
Compliance Evaluation Inspection Report
Harbor Estates WWTP, Mecklenburg County
NPDES Permit No. NCO063860
Tracking #: NOV-2019-PC-0689
Dear Mr. Basinger:
www.aquanorthcarolina.com
Aqua North Carolina, Inc. (Aqua) offers the following response to the items outlined in the above -
referenced Compliance Evaluation Inspection Report which was issued for the inspection conducted on
September 25, 2019:
Operations and Maintenance
A significant hole in the metal structure was observed in one of the aeration basins. In addition,
the internal metal structure (including the metal piping system) throughout both aeration basins
appeared significantly corroded and deteriorated.
Agua's Response: The inspectors report indicates a hole above the water line in the aeration basin.
No discharge of wastewater has occurred due to this, however Aqua has contacted a contractor to
weld a patch and paint the area of the hole. This small repair will be made within the next 60 days.
The inspectors requested to have Aqua conduct a full evaluation of the structural integrity of the
metal structure by a structural engineer professionally certified in NC is not reasonably possible in
the time frame allowed by the inspection report.
Aqua has installed a baffle at this facility which will allow one-half of the aeration basin to be
emptied at a time, and for the basin to be professionally coated after appropriate surface preparation.
This is a major project and has been included in our capital improvement plan to be completed in
the next two years.
