An updated results table is also enclosed. USM is currently monitoring monthly due to "tier three" status for copper at all outfalls and zinc at Outfalls 003 and 004. After this monitoring event, analytical results for zinc from Outfalls 001 and 002 have been below the benchmark concentration for three consecutive events. As noted in prior DMR correspondence, installation of Regenerative Stormwater Conveyances at Outfalls 003 and 004 were completed in the month of November 2020, however, USM is having difficulty achieving consistent copper and zinc results near benchmark concentrations at those outfalls. As a result, USM requests a second technical review from the NCDEMLR, which will provide regulatory assessment of efforts completed to -date and perhaps some valuable insight into future compliance activities that may be necessary based on other sites in the region struggling with the same parameter benchmark concentrations. Should you have any questions or comments, please do not hesitate to contact me at 804-621-7000 or mobile phone 815-693-5052. Sincerely, UNITED SCRAP METAL, INC.
