Dear Mr. Bennett,

CENTI- AL FILES
DWR SECTION
On August 7, storm water samples were taken during a qualified rain event for the first half sample of
the 2018 calendar year for the four outfalls. On August 7, we received 1.13 inches of rain in
approximately 2 hours. Samples were collected for outfalls #1, #2, #3, and #4. The resulting storm water
flow was calculated to be 0.07 MMgal for Drainage Basin #1, 0.39 MMgal for Drainage Basin #2, 0.40
MMgal for Drainage Basin #3, and 0.42 MMgal for Drainage Basin #4. All three of the samples are
slightly high in cooper and we are investigating as required. The test for TSS in sample 4 was higher than
expected. We will investigate as required. 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, ENS Engineer, at (919)-693-1141, ext 2114.
Sincerely,
Ma Heilman

SUBJECT: Analytical Monitoring Report
NPDES Stormwater Permit
CertainTeed Corporation
Permit Number NCS000140
Granville County
Dear Mr. Bennett,
On March 6, storm water samples were taken during a qualified rain event for the first half sample of
the 2018 calendar year for the four outfalls. On March 6, we received 0.62 inches of rain in
approximately 13 hours. Samples were collected for outfalls #1, #2, #3, and #4. The resulting storm
water flow was calculated to be 0.04 MMgal for Drainage Basin #1, 0,21 MMgal for Drainage Basin #2,
0.22 MMgal for Drainage Basin #3, and 0.23 MMgal for Drainage Basin #4. All three of the samples are
slightly high in cooper and we are investigating as required. The test for TSS in sample 3 was higher than
expected. We will investigate as required. 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,
Marc Heilman

Dear Mr. Bennett,

RECEIVED
OCT 06 2D17
CENTRAL FILES
DWR SECTION
On September 2, storm water samples were taken during a qualified rain event for the second half
sample of the 2017 calendar year for the four outfalls. On September 2"d, we received 0.93 inches of
rain in approximately 14 hours. Samples were collected for outfalls #1, #2, #3, and #4. The resulting
storm water flow was calculated to be 0.06 MMgal for Drainage Basin #1, 0.32 MMgal for Drainage
Basin #2, 0.33 MMgal for Drainage Basin #3, and 0.34 MMgal for Drainage Basin #4. The copper
numbers were below benchmark on two samples. One of the samples is slightly high and we are
investigating as required. 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 me at
(919)-693-1141, ext 2114.

SUBJECT: Analytical Monitoring Report
NPDES Stormwater Permit

Permit Number NCS000140
Granville County
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 August I9th, 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 MMga1 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,

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 August I9th, we
received 0.28 inches of rain in approximately l 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,
Robert Yurek V

SUBJECT: Analytical Monitoring Report Lr
NPDES Stormwater Permit CertainTeed Corporation
Permit Number NCS000140 Granville County
Dear Mr. Bennett,
On April 1, 22, and May 17 of 2016, storm water samples were taken during a qualified rain
event for the first half sample of the 2016 calendar year for the four outfalls. On April I", we
received 0.17 inches of rain in approximately 3 hours and sampled outfall #1. On April 22°d,
we received 0.18 inches of rain in approximately 2 hours and sampled outfalls #2, #3, and
#4. The resulting storm water flow was calculated to be .01 MMgal for Drainage. Basin #1,
.06 MMgal for Drainage basin 42, .06 MMgal for Drainage basin #3, and .06 MMgal for
Drainage basin 94. The reason for the separate samples was that only Drainage basin #1
overflowed. It was dry for 2 weeks before this rainfall. Since it was so dry when the rainfall
did overflow Drainage basin #3 the sample from initial flow appeared to be extremely
contaminated with organic material from the exit pipe. This contamination was confirmed
with a high TSS result. An extra sample was taken from a .95 inch rainfall in
approximately5 hours on 5/17/16. The resulting stormwater flow was calculated at .32
MMgal. 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- l 141, ext. 2221.

On March 30, 2015 a storm water sample was taken during a qualified rain event for the first
half sample of the 2015 calendar year for the four outfalls. On March 30th, we received 0.10
inches of rain in approximately 3 hours and sampled all four outfalls. The resulting storm
water flow was calculated to be .01 MMgal for Drainage Basin #1, .03 MMgal for Drainage
Basin #2, .03 MMgal for Drainage Basin #3, and ..03 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.

Dear Mr. Bennett,
April 7, 2017
RECEIVED
APR 12 2017
CENTRAL FILES
DWR SECTION
On February 15, 2017 a storm water sample was taken during a qualified rain event for the
first half sample of the 2017 calendar year for the four outfalls. On February 15th, we
received 0.22 inches of rain in approximately 3 hours and sampled all four outfalls. The
resulting storm water flow was calculated to be .01 MMgal for Drainage Basin #1, .07
MMgal for Drainage Basin #2, .07 MMgal for Drainage Basin #3, and .07 MMgal for
Drainage Basin #4. The copper numbers were lower than benchmark on one of the
samples. The other samples were slightly high and we 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,
Robert Yurek

SUBJECT: Analytical Monitoring Report
NPDES Stormwater Permit

Permit Number NCS000140
Granville County
Dear Mr. Bennett,
On February 21, 2014 a storm water sample was taken during a qualified rain event for the
first half sample of the 2014 calendar year for the four outfalls. On February 21 st, we
received 3.04 inches of rain in approximately 3 hours and sampled all four outfalls. The
resulting storm water flow was calculated to be 0.18 MMgal for Drainage Basin 41, 1.01
MMgal for Drainage Basin #2, 1.03 MMgal for Drainage Basin #3, and .96 MMgal for
Drainage Basin #4. The copper numbers were higher than benchmark for DB #2, DB #3,
and DB 44 this sample. We are continuing to investigate and analyze the copper issue. 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.
Ecerely,
Yurek

SUBJECT: Analytical Monitoring Report
NPDES Stormwater Permit
CertainTeed Corporation
Permit Number NCS000140
Granville County
Dear Mr. Bennett,
On July 15, 20t4 a storm water sample was taken during a qualified rain event for the
second half sample of the 2014 calendar year for the four outfalls. On July 15th, we received
1.42 inches of rain in approximately 7 hours and sampled all four outfalls. The resulting
storm water flow was calculated to be 0.09 MMgal for Drainage Basin #1, .47 MMgal for
Drainage Basin #2, .48 MMgal for Drainage Basin #3, and .45 MMgal for Drainage Basin
#4. The copper numbers were lower than benchmark for all 3 required samples. 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,
AL-C�

July 6, 2010,
On June 13'h, 2010 a storm water sample was taken during a qualified rain event for the,
Spring sample of the 2010 calendar year for the four outfalls. On June 13'h, we received 2.55
inches of rain in approximately 19 hours and sampled all four outfalls. The resulting storm
water flow was calculated to be 0.27 MMgal for Drainage Basin #1, 1.05 MMgal for
Drainage Basin #2, .92 MMgal for Drainage Basin #3, and .90 MMgal for Drainage Basin
#4. 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.

Dear Mr. England

February 12, 2001
On January 8, 2001 a storm water sample was taken during a qualified rain event for the
2000 calendar year. We received 0.12 inches of rain in approximately 6 hours. The
resulting storm water flow to Outfall A was calculated to be 0.10 MMgal. Based on my
conversation with you concerning representative outfall status, Outfall 91 was the only
outfall sampled. I have not yet received a reply from Bradley Bennett to my letter dated
November 3, 2000 concerning this matter. 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. 2222.

Dear Mr. Bennett,
On May 28`}', 2008 a storm water sample was taken during a qualified rain event for the Fall
sample of the 2008 calendar year for the four outfalls. On May 28`h, we received .51 inches
of rain in approximately 7 hours and sampled all four outfalls. The resulting storm water
flow was calculated to be 0.05 MMgal for Drainage Basin #1, .21 MMgal for Drainage
Basin #2, .18 MMgal for Drainage Basin #3, and .18 MMgal for Drainage Basin #4. 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.
