Subject: Relief from Monthly Monitoring
Stormwater Permit # NCG030670
Fontaine Modification Company
Mecklenburg County
We are in receipt of your July 8, 2020 email requesting relief from monthly- monitoring at the
Fontaine Modification Company Charlotte plant. Based on past site inspections, including July 29, 2020, 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 NCG030670 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 May 31, 202 L . 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 and the
TSS abatement plan at the- Fontaine Modification. Company 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.
