e 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.
How rate can be measured continuously or calculated. Flow limits for wastewater discharges to HOW waters shall be 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�p'ermittee 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.
