Bethany and Alaina,
As I just seen from my previous email, I know that Mr. James Moore retired recently, so I am sending this information to
you for CommScope, Inc, - Claremont Facility (COC NCG030650).
Per the general permit for CommScope, Inc. (NCG030000) — Claremont Facility (under COC NCG030650), sampling was
completed on ROS Outfall 003 for the site on February 3rd, 2022 with a rainfall even totaling 0.28" of rain. I received
results from the laboratory (Statesville Analytical) this past Tuesday, February 22nd, 2022. For this event, all parameters
were below the benchmark EXCEPT for Copper and Zinc. Please note that following:
1) The benchmark for Copper under General Permit NCG030000 is 0.010mg/L. The result obtained for Copper
for Outfall 003 was 0.085 mg/L, which exceeded the benchmark of 0.010 mg/L.
2) The benchmark for Zinc under General Permit NCG030000 is 0.126 mg/L. The result obtained for Zinc for
Outfall 003 was 0.33 mg/L, which exceeded the benchmark of 0.126 mg/L.
3) These exceedances will be documented in the SWPPP, and corrective action steps will be implemented to
reduce these exceedances. Furthermore, best management practices will be utilized to assist with this
reduction as well.
Please let me know if you need anything further, and hope you both have a very blessed day. Thank you for your
assistance with this matter. Please feel free to call me at 336-366-0870 if you need any further information.
