A stormwater sample was collected from Outfall 001 on December 9, 2019 and analyzed for total suspended solids (TSS), pH, total recoverable lead, oil and grease and ethylene glycol. As indicated on the attached DMR, all parameters were reported below or within their respective benchmark values. If you have any questions or need additional information, please contact me at 919-250-9918. Sincerely, MID -ATLANTIC ASSOCIATES, INC. Paul W.

Readings from an on -site or local rain gauge (or local precipitation data) must be documented to demonstrate background concentrations were below the benchmark pH range of 6-9. 2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters. 3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.
