NCG020000 Vulcan Materials Company, LLC (Vulcan) is submitting notification within the 30 days of receipt of analytical results indicating an exceedance of a benchmark value as outlined in Part V Section E. A copy of the discharge monitoring report for the above referenced facility, which includes the laboratory report received on November 13, 2020, is provided as Attachment 1. Vulcan is in the process of implementing the Tier One response requirements for Total Settleable Solids exceedances as detailed in Part IV, Section A of General Permit No. NCG020000. Specifically, Vulcan attempted to the identify and evaluate the possible causes of the benchmark exceedance within one week of being notified of the results. The exact cause could have been from sediment build up along the spillway weir section. The facility plans to take another sample during the next qualified storm event. The pond spillway riprap filter stone section is scheduled to be cleaned and new filter stone replaced. Documentation of all responses in accordance with the Tier One requirements for turbidity will be maintained with the facility's Stormwater Pollution Prevention Plan. If you have any questions ab u above information, please contact Bert Bond, Plant Supervisor at 336- 998-3838 or m ,-at 704-547-7076 Sincerely, Tony Johnson Environmental Engineer cc: Tamera Eplin, NCDEQ-MRO Bert Bond CHARLOTTE REGIONAL OFFICE — VULCAN CONSTRUCTION MATERIALS, L.L.C. 11020 David Taylor Drive, SUITE 105, CHARLOTTE, NC 28262, TELEPHONE 704-549-1540, FAX 704-549-4137 Certificate of Coverage No. NCG020081 Additional Outfall Attachment (make copies as needed for additional outfalls) Stormwater Discharge Outfall (SDO) No. 003 VMA Outfall?
