s 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 0213,0224, Permittees who discharge wastewater to HQW waters shall obtain a Summer7Q10 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.
