NC,G1.OQ062 To Whom It May Concern: Attached please find the Stormwater Discharge Monitoring Report (DMR) and analytical report for the sampling conducted at the above-referenced site. A stormwater sample was collected from Outfall 001 on June 28, 2016 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, with the exception of lead. Please note that a Tier One Response has previously been implemented at the site, Best Management Practices are in place and batteries are stored indoors and under cover at all time. Therefore, the current and historical lead exceedances detected in stormwater runoff at the site are interpreted to be the result of. naturally-occurring lead present in the native site soils. If you have any questions or need additional information, please contact me at 919-250-9918. Sincerely, MID-ATLANTIC ASSOCIATES, INC.

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.
