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.
s 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 VIVA 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 So%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 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.
