To Whom it May Concern:
Attached please find the Stormwater Discharge Monitoring Reports (DMR) and analytical
report for the sampling conducted at the above -referenced site. A stormwater sample was
collected from Outfall 001 AND 002 on June 16, 2020 and analyzed for total suspended
solids (TSS) and oil and grease (O&G), Chemical Oxygen demand (COD), Ph, Lead (P,
Copper (Cu), and Zinc (Zn). As indicated on the attached DMR, all parameters were
reported below or within their respective benchmark values except for copper. Based on
these results, a Tier One Response has been implemented at the facility. If you have any questions
or need additional information, please contact me at 919-250-9918.

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The 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.
a See General Permit text, Table 3 or Table 4, identifying protected receiving water classifications where the more protective TSS benchmark applies.
s Stormwater discharges into receiving waters classified as, saltwater are subject to the second listed benchmark.
Note: Results must be reported in numerical format. Forlexamnle, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format. "<XX ma/l." where XX is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark you must implement Tier 1 Tier 2 or Tier 3 responses See General Permit
