December 2016 Stormwater DMRs
To Whom It May Concern:
I have enclosed two (2) copies of the December 2016 Stormwater DMR for
CommScope, Inc. WWTP. The CommScope Certificate of Coverage No. is NCG030650.
For this month, CommScope - Claremont completed a wet sampling event of all three
(3) outfalls for the facility on Tuesday, December 6th, 2016. All three (3) outfalls were
monitored for oil & grease, TSS, pH, lead, copper, and zinc.
For this sampling event, the following exceedances from the General Stormwater Permit
were noted:
Outfall # Copper (0.007 mg/L) ' Zinc 0.067 ms/L)
N/A i ®D129
--''Q� -- N/A ! @j39

From the above, it is noted that all three (3) outfalls were above the benchmark
exceedance for zinc (0.067 mg/L). Outfall 003 was above the benchmark exceedance
for copper (0.007 mg/L).
Due to these exceedances, the Stormwater Pollution Prevention Team (SWPPT) will be
implementing the following corrective action steps:
1) Perform increased sampling events to further investigate these exceedances;
2) Perform monthly dry weather inspections during months of no discharge; and
3) Follow up with necessary Best Management Practices as identified in the
Stormwater Pollution Prevention Plan.
As the above corrective action steps are implemented, the SWPPT will work on
addressing the causes for these exceedances. Furthermore, the SWPTT will
continuously follow up with necessary Best Management Practices as needed from
henceforth.
Please feel free to call me at 828-459-5153 to discuss this information further.
Sincerely,
_fro,-7,-,...

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11;for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief,no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL, <PQL, Non-detect, ND, or other similar non-numerical
format. When results are below the applicable limits,they must be reported in the format, "<XX mg/L", where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See Genera!Permit text.
