1 If wastewater systems have not discharged in this quarter — report "No Flow" or "No Discharge" here. Please make sure to mark the sample quarter above.
z Report the abbreviation for the type of Authorized Wastewater Discharges here: Vehicle and Equipment Cleaning (VE), Raw Material Stockpiles (RM), Mixing Drum

3If 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 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 7Q10 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.
