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. Vulcan's contract laboratory contacted Vulcan in late December to inform us that the turbidity levels in the samples for Outfalls 002 and 005 were potentially above the benchmark values(note that the laboratory results were received on December 31, 2019). A copy of the discharge monitoring report for the above referenced facility,which includes the laboratory report received on December 31,2019, is provided as Attachment 1. Vulcan is in the process of implementing the Tier One response requirements for turbidity 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 of the exceedance was unknown at the time and therefore, the facility took another sample during the next qualified storm event. The results of the second sample have indicated that the turbidity results were significantly less than the benchmark value(both samples were reported at <1 NTU). A copy of the second sampling event analytical report is provided as Attachment 2. Although it appears that there does not appear to be a turbidity issue at these outfalls at this time,as part of the Tier one process, Vulcan plans to continue its research into potential causes of the exceedances and make improvements to our 002 and 005 Outfall structures in the near future. 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 about the above information,please contact Corey Duke,Plant Supervisor at 704-788-7833 or me at 704-547-7076.
