Subject: NPDES Permit Renewal for NC0034754 RECEIVEDIDENR/DWR
JAN 2 3 2015
Dear Mr. Thedford: Water Quality
Permitting Sectior
CommScope, Inc. wishes to renew the current NPDES Permit # NC0034754. We are
also noting several facility changes that are provided in this letter that have occurred
since the last issuance of the permit. Furthermore, for this renewal, there are several
items that need to be changed from the permit.
For the facility changes, please note the following:
1) Outfalls 002, 003, and 004 are not usable anymore. They are no longer
operable due to the removal of all pipes, pumps, and plugging any egress of
water to these designated areas. To be specific, these discharge points that
lead to outfalls 002, 003, and 004 from the CommScope facility were filled
with concrete and are not accessible for use at all. These outfall discharge
points need to be removed from the WWTP permit, since these contact
cooling water discharges have been eliminated. However, we are planning
on changing our discharge point 001 to discharge 002, since both are
approved in the current permit NC0034754. We plan to pump the effluent
discharge from the current onsite effluent manhole to discharge 002.
Therefore, we can abandon Outfall discharge 001. We only need one
discharge point from hence forward, which should be discharge 002.
a. The current outfall 001 is at Latitude 35° 38' 58.3" N and Longitude
81° 1' 49.9" W.
b. We need to move discharge 001 to discharge 002 which is Latitude
36.658422 N and Longitude 81.033346 W. Furthermore, we need to

change discharge 002 to discharge 001, since we will have only one
outfall. 002 will now become 001. This outfall discharges into the
pond on the north side of the property.
2) Due to changing the discharge point to Outfall 002, which will be renumbered
as Outfall 001, as well as CommScope considered a Minor Industrial
Discharge, the permit limits for NH3-N, BOD, TSS, Acute Toxicity, and Oil &
Grease need modifications. Please also see #3 below.
3) Based on the DMR data collected for years 2012 through 2014, the enclosed
spreadsheet provides documentation that the permit limits for NH3-N, BOD,
TSS, Acute Toxicity and Oil & Grease should be evaluated. The following
table provides the needed monitoring requirements:

4) The facility has monitored oil &grease analysis for years. During these
analysis, data has been non-detect for all analysis for oil &grease except for
one that was identified as a recent lab error (since the very next day was
non-detect). Anyway, the attached spreadsheet for parameter analysis
(including oil &grease) for the past three years of DMR data provides this
confirmation. Also, please note that this spreadsheet was also used for the
parameter listing for items 12 and 15 for the attached permit application
Form C-MI.

5) The new permit also needs to eliminate the following treatment components,
which are no longer being used:
a. The dual tertiary sand filters are not currently being utilized and are
not required to meet permit limits.
b. The sodium hypochlorite chlorination addition and contact chamber
have been replaced by ozone. Furthermore, the sodium sulfite
dechlorination addition is no longer needed. Staff can utilize sodium
hypochlorite and sodium sulfite tablets as backup if needed (as per
their 0 & M manual).
If you should have any questions concerning information contained in the report, please
feel free to contact our Environmental Consultant, Nicole Johnston, at 336-366-0870 or
feel free to call me if needed. Ms. Johnston completed this renewal package for our
facility and has been authorized by me to speak to NCDENR as needed. Thank you for
your time and consideration.
