s Process wastewater discharges shall only he 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.
' Flow rate can be measured continuously or calculated. Flow limits for wastewater discharges to HQW waters shall be set to 50% of the Summer 7QV0 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 tho'permittee cannot
