Subject: Relief from Monthly Monitoring
Stormwater Permit # NCG030630-
Harper Corporation of America
Mecklenburg County
We are in receipt of your July 27, 2021 email requesting relief from monthly monitoring at the
Harper Corporation of America Charlotte plant. Based on past site inspections, including August 4,
2021, and email correspondence regarding copper, zinc and implementation of a TSS abatement
plan and onsite pH monitoring, the facility is in compliance with the tiered response actions and other
conditions of the NCG030630 Permit. Therefore, the Division is granting regulatory relief from the
Tier responses. Upon receipt of this letter, the subject facility may resume the permit specified 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. 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 at the
Harper Corporation of America 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.
