To Whom It May Concern:
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 is either recycled back into the batch plant operations or collects/
evaporates in the retention pond located on the southern portion of the site. In the event of an
overflow from the on -site retention 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 monitoring period
(January -March, April -June, July -September and October -December 2020) 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.
