A stormwater sample was collected from Outfall 001 and 002 on Jun 10, 2020 and analyzed for total suspended solids pH, lead (Pb), copper (Cu), zinc, (Zn), (TSS) and oil and grease (O&G). 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. AicAree Paul W.

'The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement. 'See General Permit, Section B,Table 1 to identify the especially sensitive receiving water classifications where the more protective benchmark applies. 'Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11;for semiconductor manufacture use the definition as found in 40 CFR 469.12;for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).

The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ the TTO monitoring waiver,the discharger shall sign the following certification statement: "Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I certify that to the best of my knowledge and belief,no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater runoff has occurred since filing the last discharge monitoring report.
