Please find attached two copies of the Stormwater Discharge Outfall Monitoring Report for
outfalls 001, 002, and 003 as required General Permit No NCG210355.
Please note that due to past results for outfalls 1-3, we fall under Tier II/TIER III
requirements and will be submitting reports monthly. Outfalls 004, 005, and 006 are on a
semi-annual sampling schedule and were sampled in December 2019.
If there are any questions regarding this report, please contact me at [phone].

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.
4 See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, 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 me/L", where XX is the numerical value of the
detection limit, reporting 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 text.
