'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 DEMLR RO staff notifies you to
continue monitoring.
° pH limits are 6-9 S.U. for wastewater discharges to freshwaters, and 6.8-8.5 S.U. for discharges to saltwaters.
$TSS limits are 20 mg/L for wastewater discharges to HOW waters, 10 mg/L for Trout and PNA waters, and 30 mg/L for all other water classifications.
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 HOW waters shall obtain a Summer 7Q10 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.
