Subject: Issuance of NPDES Permit
Permit NC0034754
CommScope
Catawba County
Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we
are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated May 9, 1994 (or as subsequently amended).
This final permit includes the following major changes from the draft permit sent to you on December 7,
2005:
• The compliance schedule of 18 months for TRC was added for Outfalls 002, 003, and 004 in response to
your request.
• Instream monitoring requirements for conductivity and fecal coliforms were removed
from the permit based on the review of DMR data and in response to your request.
• Air compressor condensate and stormwater were removed from the description of wastewater for Outfalls
002, 003, and 004 to correct an error.
The Division reviewed your request to change BOD limit for Outfalls 002, 003, and 004. This request cannot be
granted because BOD limit of 5 mg/L is necessary to protect instream dissolved oxygen standard.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you
have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter.
This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General
Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina
27699-6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain
other permits which may be required by the Division of Water Quality or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Sergei Chernikov at telephone number
[phone], extension 594.

SUMMARY ,LC L��
• This is a minor permit renewal for a 0.02 MGD WWTP serving the CommScope facility. The
facility has 4 permitted outfalls (001-004). Presently there is no regional POTW to serve this
facility.
• The facility manufactures coaxial cable by extrusion of a plastic coating over copper -plated
aluminum wires. Contact cooling water is generated from cooling pits used to cool the
fabricated copper cable.
• Outfall 001 discharges treated domestic watewater (90%) and cable extrusion contact
cooling water (10%) on a continuous basis. Outfalls 002/003/004 previously discharged
contact cooling water to an onsite 10-acre holding pond on an episodic basis (generally once
per year), which occasionally overflowed to the same receiving waterbody as Outfall 001.
Sludge residuals are removed offsite by Catawba Septic Tank Service.
• This facility discharges to an UT Terrapin Creek (class WS-IV) which flows into Lake
Norman, an oligotrophic man-made reservoir. The receiving stream originates immediately
above the discharge point from an upstream impoundment. The receiving stream's
assimilative capacity is limited due to relatively low flow.
• Permit was modified in February 2004. Commscope wanted to "bleed in" contact cooling
water to the existing treatment system. This contact cooling water was called process water
in the description of Outfall 001 wastewater. Daily maximum values for BOD5 and TSS
were reevaluated per effluent guidelines for 40 CFR 463 Plastics Molding and Forming Point
Source Category, Subpart A — Contact Cooling and Heating Water Subcategory 463.12.
Parameter Daily Max.
BOD5 26 mg/L
Oil and Grease 29 mg/L
TSS 19 mg/L

NPDES PERMIT FACT SHEET CommScope, Inc.
Page 2 NPDES No. NC0034754
Calculations using domestic and contact cooling (process) flows at the time of 2004 permit
modifications determined that the daily max. limit for summer BOD5 should not exceed the
existing 24 mg/L. Daily max winter BOD5 limit was calculated to be 40.7 mg/L. A daily max.
TSS limit of 39.2 mg/L was also calculated. These existing limits for Outfall 001 will be applied
during this permit renewal.
Limits for Outfalls 002, 003, 004.
Existing limits will be recommended. BOD5 limit of 5mg/L is based on protections of dissolved
oxygen standard instream, BOD5 of 26 mg/L would violate such standard. Previous model
indicated that more protective limits shall be given.
REASONABLE POTENTIAL ANALYSIS
There are no metals limited or monitored in the current permit. RPA was not conducted.
INSTREAM MONITORING:
Currently Temperature, DO, Fecal Coliform and Conductivity are monitored. Analysis of
instream data indicates that the facility has no significant negative impact on the water quality
in the receiving stream
TOXICITY TESTING:
Type of Toxicity Test: Chronic P/F @ 34% for Outfall 001. February, May, August, November
Acute Toxicity for Outfalls 002, 003, 004.
No changes are recommended.
COMPLIANCE SUMMARY:
This facility has a good compliance record and appears to be well operated. Limits for BOD5,
TSS, 086G are consistenly met. One violation of fecal Coliform limit occurred in 2002, and two
violation of chronic toxicity limits: 02 / 2001 and 09 / 2004.
PROPOSED CHANGES:
• Limits. Weekly average limits for ammonia nitrogen have been added to the permit
based on the new DWQ policy adopted October 2002. The TRC limit for cyanide has
been added to the permit.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: December 12, 2005 (est.)
Permit Scheduled to Issue: January 30, 2006 (est.)
STATE CONTACT:
If you have any questions on any of the above information or on the attached permit, please
contact Sergei Chernikov at [phone] ext. 594.
CHANGES IN THE FINAL PERMIT:
• The compliance schedule of 18 months for TRC was added for Outfalls 002, 003, and
004.
• Instream monitoring requirements for conductivity and fecal coliforms were removed
from the permit based on the DMR data and in response to permittee's request.
• Air compressor condensate and stormwater were removed from the description of
wastewater for Outfalls 002, 003, and 004 to correct an error.
• Commscope also requested removal of Chronic Toxicity testing for Outfall 001, but after
the visit to the plant and telephone discussion on 06/11/2007 Scott Waddell requested
that this requirement remains in place to give CommScope the option of treating contact
cooling water at their WWTP.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
CommScope is requesting renewal of its existing NPDES permit with no modifications. The
facility discharges domestic and process wastewater. The application states sanitary flow is
165,000 gal/month (-5500 GPD) and the process water is 45,000 gal/month (-1500 GPD).
CommScope produces coaxial and trunk cable. The main process is plastic extrusion. Raw
materials consumed are copper, aluminum, PVC & PE Plastics.
CommScope has 4 outfalls. Historical info states that 001 discharges domestic and process
water. Outfalls 002, 003 and 004 discharge contact cooling water from cooling pit dump.
Permit was modified in February 2004. CommScope wanted to "bleed in" contact cooling water
to the existing treatment system. This contact cooling water was called process water in the
description of Outfall 001 wastewater. Daily maximum values for BOD5 and TSS were
reevaluated per effluent guidelines for 40 CFR 463 Plastics Molding and Forming Point Source
Category. Subpart A- Contact Cooling and Healing Water Subcategory 463.12
Parameter Daily Max.
BOD5 26 mg/1
Oil& Grease 29 mg/1
TSS ' 19 mg/1
pH 6-9 SU
Calculations using domestic and contacting cooling (process) flows at that 2004 permit
modification determined that the daily max. limit for summer BOD5 should not exceed the
existing 24 mg/1. Daily max. winter BOD5 limit was calculated to be 40.7 mg/1. A daily max.
TSS limit of 39.2 mg/l was also calculated. These existing limits for Outfall 001 will be given in
this permit renewal.
Limits for Outfalls 002, 003, 004
Existing limits will be recommended. BOD5 limit of 5 mg/1 is based on protection of dissolved
oxygen standard instream, BOD5 =26 mg/1 would violate.. Previous model that indicated that
more protective limits must be given.

RECEIVING STREAM INFO
All the Comm Scope outfalls discharge to an unnamed tributary to Terrapin Creek in CTB32.
The stream has a WS-IV classification. The receiving stream has low 7Q10 flow but it is
considered positive flow, i.e. > 0.05 cfs.
The stream has not been evaluated for use support and there is no biological data on the
stream. Further downstream Terrapin Creek drains into Lake Norman.
TOXICITY TESTING:
Outfall 001
Current Requirement: Chronic Toxicity P/F @ 34%; February May August November
Since January 2001, facility has had two FAILs in February 2001, and in August 2004.
Recommend continuation of Chronic Toxicity P/F © 34%; February May August
November
Outfalls 002, 003, 004
Current Requirement: Acute Toxicity (Fathead Minnow, 24-hour) Monitoring: Episodic
For the most part, these outfalls are active but not discharging.
Outfall 002 discharged once from January 2001 to Sep 2005: in Sep 2004 at 32.5%
Outfall 003 did not discharge from January 2001 to Sep 2005
Outfall 004 last discharged in March and April 2003; at >100% and 46.3%. Did not discharge
any others
Recommend continuation of Acute Toxicity Monitoring (Episodic)- Fathead Minnow)
COMPLIANCE SUMMARY:
Facility appears to be well operated. Limits for BOD5, TSS, O&G are consistently met. One
violation of fecal coliform limit in 2002. A violation of chronic toxicity limit in 2004.
INSTREAM MONITORING REQUIREMENTS:
Current requirements: Temperature, DO, Dissolved Oxygen, Conductivity
Recommendation: Renewal of all instream monitoring requirements
REASONABLE POTENTIAL ANALYSIS.
There are no metals limited or monitored in the current permit. No RPA was run.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• The addition of a Total Residual Chlorine limit of 28 ug/1 to all outfalls based on DWQ
procedure for all facilities that use chlorine for disinfection. Eighteen month
compliance schedule will be given_
• Weekly average limits for NH3 of 10 mg/1 (summer) and 21.5 (winter) will be given
based on DWQ procedure. Limits were calculated at 5 times the existing monthly NH3
limit.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE:
Draft Permit to Public Notice: 12/07/2005
Permit Scheduled to Issue: Tentatively 01/30/2006

AMENDMENT TO THE FACTSHEET
Comments received from CommScope
- Asked for 18 month schedule to achieve TRC limit DWQ will concur with this
request because schedule was omitted from draft permit.
Asked that "air compressor condensate and Stormwater" be removed from description
of wastewater from 002, 003 and 004. DWQ will concur because this description
was taken from very outdated permit copy and inadvertently included.
Asked that chronic tox testing be deleted since facility has not received contact
cooling water for 14. months. Hardpiping still connected and CommScope will remove
after tox test is eliminated. NPDES consulted with Aquatic Toxicity and Matt M.
stated that test cannot be eliminated until hardpiping has been disconnected
and the tox test failure in August 2004, gives them concern with eliminating
the chronic test. Recommends continuation of tox test for two years after
disconnection from source of contact cooling water.
Request deletion of fecal, pH and conductivity instream monitoring. DWQ will
concur. It should be noted that there was no requirement for instream pH
monitoring.
Requests that BOD5 limit be modified from 5 mg/1 to 26 mg/1 (effluent guideline) at
outfalls 002, 003, 004. DWQ response; WLA notes shows that BOD5 limit based on
protection of DO standard instream. BOD5=26 mg/1 will violate DO standard in the
stream segments that have very low summer 7Q 10 flow.

This letter is in response to the Draft NPDES Permit received by my office on December
12, 2005. In review of the draft permit several items arose which are of concern.
1) While the new chlorine residual limit of 28 ug/I was added to outfalls # 1, 2, 3, &
4 along with new weekly average limits for ammonia nitrogen for outfall #1, no
schedule of compliance was mentioned. While the ammonia nitrogen limit
doesn't really affect our daily operation of the plant, the chlorine limit is
substantial. We are unclear if the current technology employed at the plant can
reduce chlorine to the permit limit without jeopardizing other analytical
monitoring (i.e. chronic toxicity testing — Ceriodaphnia dubia). As a result,
CommScope is requesting a schedule of compliance date of no less than 18
months from the start date of the new NPDES Permit.

2) It was noted on page #2 "Outfalls 002, 003, 004 " and in section A (2) that "air
compressor condensate, and Stormwater" was added to the wording to the
Effluent Limitation s and Monitoring Requirements section for Outfall #2, 3 & 4.
CommScope is already monitoring Stormwater through its Stormwater Permit
(Certificate of Coverage # NCG030078) and feels that this requirement is
redundant and unjustified. Also, this requirement would require monitoring every
quarter during the 1S` rain event of that quarter. I feel that the requirement to
monitor Stormwater and air compressor condensate (while not listed on our prior
permit) is unjustified and should be removed from the permit.
3) CommScope is requesting to eliminate Chronic Toxicity testing. The WWTP has
not received contact -cooling water for approximately 14 months. Due to the
elimination of this wastestream, Chronic Toxicity should not be required. Hard
piping at this time has not been disconnected, however, if the Chronic Toxicity
requirement is removed, CommScope will proceed in making the necessary
physical changes needed to ensure full compliance.
4) As a result of removing the Chronic Toxicity requirement, CommScope requests
that the following upstream and downstream testing requirements be removed
from the permit:
a. Fecal
b. pH
c. Conductivity
We ask that upstream and downstream sampling consist of DO and Temperature.
5) CommScope's EHS department (Catawba Facility) on several occasions has had
conversations with the state concerning the BOD5 limit for an episodic contact
cooling water discharge to our receiving pond. Please note that these
conversations were informal in nature. Our concern is with the strict BOD5 limit
placed on this discharge. The limit is currently set at 5 mg/1 per event with a
sample to be taken upon the first discharge from the facility during each quarter.

Quarter is defined as a calendar quarter. EPA's subpart A, section 463.12
"Contact Cooling and Heating Water Subcategory" notes BOD5 concentrations at
26 mg/1 to calculate BPT effluent limitations. Discharge of contact cooling water
to outfall # 2, 3 & 4 is not normal practice. The only time when this occurs is
during a process upset where the cooling pits are overfilled with water and thus
will discharge. This will usually happen in the event of a float malfunction. The
pits are cleaned out on an annual basis and the water is hauled off for treatment.
(Bills of Lading documentation is available upon request). As such, it is the
request that the BOD5 limit be raised from 5 mg/1 to 26 mg/1 as referenced in
section 463.12 Subpart A.
Thank you for your time in reviewing these requests. If you should have any questions
please feel free to contact me @ 828-241-6147.

4. Alternative analysis evaluation
a. Spray Irrigation: Insufficient area.
b. Connect to regional sewer system: Presently there is no regional sewer system
available to serve this facility.
c. Subsurface: Insufficient area.
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, CommScope, has requested renewal of the subject permit. There have
been no changes to the permit since the permit was last renewed, however, there were some
additions to the WWTP that were approved in ATC No. 034754A01 (issued December 18,
2001), which were implemented during the term of the current permit.
CommScope has been advised of the impending inclusion of a total residual chlorine
(TRC) limit added to the permit upon renewal. Mr. Waddell informed the writer that their
current testing equipment was not capable of detecting TRC at levels consistent with the
anticipated limit. Mr. Waddell then asked that additional time be provided in the renewed permit
to effect equipment upgrades necessary to meet the new limit. However, subsequent
conversations with MRO staff revealed that CommScope's existing equipment may indeed be
capable of reading TRC levels consistent with the Division's new TRC policy. It is, therefore,
recommended that clarification be provided by CommScope as to their ability to analyze TRC at
the levels anticipated in the renewed permit before any consideration is given to providing
additional time for CommScope to make any equipment changes and/or upgrades.
CommScope is also considering removing the process water component from the
wastestream tributary to outfall 001. This would result in the existing WWT facilities
discharging through outfall 001 treating purely domestic wastewater. If this occurs, CommScope
has indicated that they may request that toxicity testing be removed from the monitoring
requirements at this outfall. If such as request is submitted, the Aquatic Toxicology Section will
need to determine whether such a request is justifiable. It is likely, given the low flow in the
receiving stream (CommScope's effluent typically dominates normal stream flow), and the fact
that CommScope has had toxicity failures in the past, that elimination of the toxicity testing
requirement would not be granted.

It is recommended that the NPDES Permit for this facility be renewed as requested
