Please make sure to mark the sample quarter above. 2 Report the abbreviation for the type of Authorized Wastewater Discharges here: Vehicle and Equipment Cleaning (VE), Raw Material Stockpiles (RM), Mixing Drum Cleanout (MD). Report more than one type if the waste -stream is commingled. 3If an effluent limit is exceeded twice in a row, the permittee is required to institute monthly monitoring for that parameter for six months, unless DWQ RO staff notifies you to continue monitoring. 4 pH limits are 6-9 S.U. for wastewater discharges to freshwaters, and 6.8-8.5 S.U. for discharges to saltwaters. 5 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 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 02B .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 report on a case-by-case basis.

This facility is in low production: Oct 8`h -1" / 3 qualifying samples taken, sample was below threshold No gualifying discharges in January. February or March 2014. We will continue to monitor monthly until we achieve 3 consecutive satisfactory results. Any testing that can be performed, will be performed and reported as required. 7130/14 Our Plant manager took Storm Water Samples on 5/15/14 during a flash flood The plant had -2.2" of rain in 3 hours The plant's runoff controls were not effective due primarily to the volume We have exceeded the TSS threshold by 50% We will continue to monitor and sample the outfall on at least a monthly basis until we achieve 3 consecutive samples within specifications. 4r" Quarter 2014 - No qualifying discharges during the quarter in Quarter 2015 - No qualifying discharges during the quarter 2 n Quarter 2015 - No , gualifyingdischarge during the auarte YOU MUST SIGN THIS CERTIFICATION FOR ANY INFORMATION REPORTED: "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.
