MID-ATLANTIC JOB NO. 000R1944.04
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 during the first sampling period
(January-June) of 2016. 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 period
(July-December 2016) 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.
