Subject: Stormwater Sand Filter Bypass at COC No. NCG081037
Good afternoon, Mr. Eplin.
Reaching out to notify DEQ of a recent stormwater discharge that has recently been determined to have bypassed the
sand filter at Pond 3 at the South Charlotte Transfer Station located in Mecklenburg County(COC No. NCG081037). The
discharge has been determined to have occurred on January 9, 2024. The stormwater was sampled at that time and
there were no benchmark exceedances observed in the analytical results. We will follow up with you early next week
with more details and would like to discuss the need for dewatering of the pond so that the sand filter can be
rehabilitated.
Best Regards,
Jeff

Re: Waste Connections—South Charlotte Transfer Station Unanticipated
and Anticipated Stormwater Bypass Report
Facility Location--1710 Westinghouse Boulevard,Charlotte,NC 28273
Stormwater Discharge Permit COC No.NCGO81037
Dear Mr.Eplin,
In accordance with the National Pollutant Discharge Elimination System(NPDES)North Carolina
Department of Environmental Quality(NCDEQ)Division of Energy,Mineral and Land Resources
(DEMLR)General Permit No.NCG080000,Waste Connections of North Carolina, Inc. (Waste
Connections)submits this letter of notification to DEMLR to report a stormwater discharge that has
recently been determined to have bypassed the sand filter at Pond 3 at the Waste Connection—South
Charlotte Transfer Facility located at 1710 Westinghouse Boulevard,Charlotte,NC 28273 (COC No.
NCG081037).
The discharge has been determined to have occurred on January 9,2024. The stormwater was
sampled at that time and there were no benchmark exceedances observed in the analytical results.
Based on the lack of benchmark exceedances,it is anticipated that there are no effects of the
stormwater bypass.Please see the attached analytical results from the outfall associated with the sand
filter at Pond 3.An estimate of 23,058.7 gallons has bypassed the sand filter.
Waste Connections is coordinating with a subcontractor to repair the sand filter at Pond 3.To do so,
the subcontractor requests for Pond 3 to be dewatered. Based on the lack of benchmark exceedances
from Outfall 003,Waste Connections is looking to dewater approximately 73,500 gallons using
dewatering sediment filter bags.Until the pond is repaired,there will be periodic bypasses depending
on rain events.
If you have any questions or require additional information,please contact me at(252)455-3843 or
