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 028.0224.Permittees who discharge wastewater to HQW waters shall obtain a Summer 7Q10 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
