Dear Mr. Bennett,
On August 19, 2016 a storm water sample was taken during a qualified rain event for the
second half sample of the 2016 calendar year for the four outfalls. On Augustl9th, we
received 0.28 inches of rain in approximately 1 hours and sampled all four outfalls. The
resulting storm water flow was calculated to be .02 MMgal for Drainage Basin#1, .09
MMgal for Drainage Basin#2, .09 MMgal for Drainage Basin#3, and ..09 MMgal for
Drainage Basin#4. The copper numbers were lower than benchmark on one of the
samples. Two of the samples were slightly high and are investigating as required. Two
copies of the Stormwater Discharge Outfall Monitoring Report were sent to Central Files as
required by our permit. Should you have any questions please contact me at (919)-693-
1141, ext. 2221.
Sincerely, - E IVE
