5 TSS limits are 20 mg/L for wastewater discharges to HQW waters, 10 mg/L for Trout and PNA waters, and 30 mg/L for all other water classifications.
6 Process wastewater discharges shall only be monitored for TPH when commingled with stormwater discharges from VMA areas. TPH does not have a limit for wastewater, but instead is subject to
benchmarks and provisions of Part IV, Section A, including the Tiered Response Action.
Flow rate can be measured continuously or calculated. Flow limits for wastewater discharges to HQW waters shall be set to 50%of the Summer 7Q10 Flow as per 15A NCAC 02B .0224. Permittees
who discharge wastewater to HQW waters shall obtain a Summer 70.10 flow and report this information to DEMLR. If the permittee cannot obtain a Summer 7Q10 flow for the receiving waters at the
discharge location, the permittee shall notify DEMLR, and the DEMLR Regional Office may require an annual flow report on a case -by -case basis.

2 If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit. Tier 2
Monthly sampling shall be done until 3 consecutive samples are below the benchmark or within the benchmark range.
a TSS benchmark values are 100 mg/I, except when discharging to ORW, HQW, Trout, and PNA waters where they are 50 mg/I.
° For each sampled measurable storm event the total precipitation must be recorded using data from an on -site rain gauge.

2 If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit. Tier 2
Monthly sampling shall be done until 3 consecutive samples are below the benchmark or within the benchmark range.
3 TSS benchmark values are 100 mg/l, except when discharging to ORW, HQW, Trout, and PNA waters where they are 50 mg/I.
4 For each sampled measurable storm event the total precipitation must be recorded using data from an on -site rain gauge.
