Re: Tier III Stormwater Response
Cataler North America Corporation
Lincolnton, Lincoln County, North Carolina
General Stormwater Permit No. NCG030000
Dear Sir/Madam:
This letter and supporting documents represent a notification of a Tier III response to a fourth consecutive
exceedance of the benchmark value for zinc at Outfall No. SD07 at our facility located at 2002 Cataler
Drive in Lincolnton, North Carolina.
Date of Sampling Benchmark Results
11/23/14 0.130 mg/L
7/8/15 0.067 mg/L 0.139 mg/L
9/9/15 0.273 mg/L
10/26/15 0.235 mg/L
Note: No flow conditions prohibited sampling during June and August 2015
Our analyses indicate that zinc is entering our stormwater discharge from condensate drains on the roof
of our facility from heating and air conditioning (HVAC) units. Deposition of zinc from HVAC condensate
onto roof surfaces through evaporation during periods of dryer weather may also lead to higher initial
zinc loading at our outfalls during the early periods of stormwater events, when stormwater sampling is
specified by our permit.
A second possible source of zinc in our stormwater discharges is the result from occasional deposition of
raw material powders (of which zinc is a trace component) from our powder processing oven exhausts.
We are currently evaluating methods of better preventing powder carryover from the processing ovens
to the exhausts and intend to install filtration equipment on the oven exhausts within the next several
months (pending approval of modification of our current air quality permit).

We have sampled multiple roof -mounted HVAC condensate drains and conducted an analysis of impacts
to the receiving waters, an unnamed tributary of Larkard Creek. The attached diagram details the
sampling points and test results, which are summarized by the diagram below:
Zinc Analysis Results (Received 11/18/15)
Outfall SD06 Outfall SD07
0.045 mg/L 0.235 mg/L
From
4 0.045 mg/L .a 1 0.031 mg/L Offsite
0.042 mg/L 4 Of
Larkard Creek, flow direction
4
The results of the HVAC condensate analyses demonstrate that HVAC condensate drains are the
predominant source of the zinc in our stormwater discharges and that the impacts of the zinc in our
stormwater discharges on the receiving waters are minimal. Based on the results of our analyses, we
request a waiver of continued monthly sampling for zinc at our facility outfalls.
Should you have any questions or require additional information, please contact me by telephone at
828.970.2102 or by email at reynolds@cataler•-na.com.
Sincerely, q
