Dear Mr. Bennett,
On March 25, storm water samples were taken during a qualified rain event for the first half sample of
the 2019 calendar year for the four outfalls. On March 25, we received 0.5 inches of rain in
approximately 11 hours. Samples were collected for outfalls #1, #2, #3, and #4. The resulting storm
water flow was calculated to be 0.03 MMgai for Drainage Basin #1, 0.17 MMgai for Drainage Basin #2,
0.18 MMgai for Drainage Basin #3, and 0.18 MMgai for Drainage Basin #4. All three of the samples are
slightly high in cooper and we are investigating as required. A composite sample of rainwater was
collected during this event and tested for copper concentration with a result of 0.028 mg/L. Two copies
of the Stormwater Discharge Outfall Monitoring Report were sent to the Central Files as required by our
permit. Should you have any questions please contact Mary Torello, EHS Engineer, at (919)-693-1141,
ext 2114.
Sincerely,

D1R+R SECTION
Per the requirements of Permit # NC000140 we are submitting the Annual Summary Report for 2018.
Two copies of the Stormwater Summary Monitoring Report were sent to the Central Files as required by
our permit. We are continuing to investigate the higher than benchmark copper readings we are having.
The investigation has led us to measure the copper in the rainwater. The rainwater has shown to be
higher than the benchmark values in some cases. Should you have any questions please contact Mary
Torello, FHS Engineer, at (919)-693-1141, ext 2114.
Sincerely,
