On behalf of Concrete Service Company, Inc., this letter serves as notification that a stormwater
sample was not collected during the previous calendar year (2018). 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 -June and July -December 2019) and, in the event of a discharge,
stormwater'sampies 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.
