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.
e 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.
7 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.

DISCHARGE WAS EVIDENCED BUT A QUALIFYING SAMPLE COULD NOT BE OBTAINED - DUE TO TIMING OF DISCHARGE(S)
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.
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.
a 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 HQW waters shall be set to 50% of the Summer 7Q10 Flow as per 15A
NCAC 028 .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.

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 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.

Cleanout (MD). Report more than one type if the waste -stream is commingled.
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.
7 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 028 .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.
