Dear Mr. Waggoner:
We are in receipt of your 2019 / 2020 TSS / Metals monitoring study and your April
28, 2020 email requesting next steps at the Charlotte facility. Based on a May 21, 2020
site inspection, the facility is in compliance with the tiered response actions and other
conditions of the NCS000040 Permit. Therefore, the Division is granting regulatory relief
from the Tier responses based on the condition that the TSS Abatement / Best
Management Plan be continued and that quarterly reports documenting maintenance be
submitted to this office. Upon receipt of this letter, the subject facility may resume the
permit specified semi-annual analytical monitoring at outfalls A, B and C for the remainder
of the current permit term which expires on January 31, 2024. This decision applies to all
the permitted benchmarks. Please update your SWPP plan to reflect outfalls A, B & C as
representative for the site industrial activities.
You must notify this office, in writing, within five business days if you become
aware of any other significant source of TSS / Metals at your facility that have the
potential to be exposed to stormwater. The relief granted in this letter is contingent
upon the current industrial practices at Charlotte Pipe & Foundry Charlotte facility.
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 James Moore or me at 704-663-1699.
