2 Report the abbreviation for the type of Authorized Wastewater Discharges here: Vehicle and Equipment Cleaning (VE), Raw Material Stockpiles (RM), Mixing Drum
Cleanout (MD). Report more than one type if the waste -stream is commingled.
3 if an effluent limit is exceeded twice in a row, the permittee is required to institute monthly monitoring for that parameter for six months, unless DWQ RO staff
notifies you to continue monitoring.
4 pH limits are 6-9 S.U. for wastewater discharges to freshwaters, and 6.8-8.5 S.U. for discharges to saltwaters.
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 HOW waters shall be set to 50% of the Summer 7Q10 Flow as per 15A
NCAC 02B .0224. Permittees who discharge wastewater to HOW waters shall obtain a Summer 70.10 flow and report this information to DWQ. If the permittee cannot
obtain a Summer 7Q10 flow for the receiving waters at the discharge location, the permittee shall notify DWQ, and the DWQ Regional Office may require an annual flow
report on a case-by-case basis.

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/I, except when discharging to ORW; HOW, 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.
