Subject: Relief from Monthly Monitoring
Stormwater Permit # NCG030461
Core & Main LP
Rowan County
We are in receipt of your September 16, 2021 letter requesting relief from monthly monitoring for
another permit term for the Core & Main Cleveland plant. Based on past site inspections, including September
15, 2021, and email correspondence regarding copper and zinc, the facility is in compliance with the. tiered
response actions and other conditions of the NCG030461 Permit. Therefore, the Division is granting regulatory
relief from the Tier responses for another permit term. 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 Core & Main Cleveland
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.
