Subject: Relief from Monthly Monitoring
Stormwater Permit # NCG030591
Ward Tank and Heat Exchanger Corporation
Mecklenburg County
Dear Mr. Ward:
We are in receipt of your February 3, 2022 email requesting relief from monthly monitoring at the
Ward Tank and Heat Exchanger Corporation Charlotte plant. Based on past site inspections, including
May 19, 2021, and email correspondence regarding copper, zinc and implementation of a TSS
abatement plan, the facility is in compliance with the tiered response actions and other conditions of the
NCG030591 Permit. Therefore, the Division is granting regulatory relief from the Tier responses. Upon
receipt of this letter, the subject facility may resume semi-annual analytical monitoring for the remainder
of the current permit term which expires on June 30, 2026. This decision applies only to the copper and
zinc benchmarks and is a direct result of the site impacts from stormwater runoff from W.T. Harris
Boulevard. A benchmark exceedance of any other parameter listed in your permit will trigger the tiered
response actions as described in the general permit.
You must notify this office, in writing, within five business days if you become aware of any
other significant source of copper or zinc at your facility that has the potential to be exposed to
stormwater. The relief granted in this letter is contingent upon the current industrial practices and the
TSS abatement plan at the Ward Tank and Heat Exchanger Corporation Charlotte plant. Please
retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit. If you
have any questions or comments concerning this letter, please contact me or James Moore at 704-
663-1699.
Sincerely,
�.ameo o"t e
