On behalf of Concrete Service Company, Inc., this letter serves as notification that a stormwater
sample was not collected during the previous calendar year (2019). During this timeframe, it is our
understanding that a stormwater discharge did not occur from the designated site outfall during a
measurable storm event at a time when a stormwater sample could be safely collected (i.e. during
business hours when the facility was occupied, and preceded by 72 hours with no measurable
storm event). Stormwater flow will continue to be monitored during the upcoming monitoring
periods (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.
Charles B. Hoffman, P.G.
