On behalf of Concrete Service Company, Inc., this letter serves as notification that no discharge
occurred from the above -referenced facility's Potential Outfall 001 over the previous calendar year
(2019). Stormwater runoff either leaves the site as sheetflow, flows into the detention pond
along the southern boundary of the site and/or enters the five stage sedimentation basin and is
recycled back into the batch process. In the event of an overflow from the on -site detention
pond, the runoff would flow over a weir and discharge off -site at Potential Outfall 001.
To date, there have been no point -source discharges of stormwater from the on -site detention
pond. Stormwater flow will continue to be monitored during the upcoming sampling periods
(January -March, April -June, July -September and October -December 2020) from the designated
site outfall and, in the event of a discharge, stormwater samples will be collected per the permit
requirements. If you have any questions or need additional information, please contact me at 919-
250-9918.
Sincerely,
MID -ATLANTIC ASSOCIATES, INC.
