This plant is not manned daily and operates only intermittently.
July 27, 2017—A discharge sample was collected during flash flooding at OF1. The plant had not been in operation, discharge was in process when sampler arrived; there had been
significant rainfall earlier in the day. Unknown if a discharge had occurred at that time. Sampler took a sample in spite of the unusual high flow volume at the time as directed.
Sample results exceeded benchmarks, additional control measures have been put in place.
No other samples were obtainable during August or September.

Due to 1 consecutive exceedances on our TSS levels during the the 1ST and 2nd quarter 2013, we have instituted monthly monitoring until we achieve 3 consecutive samples within normal TSS
parameters. This facility is in low production:
Oct Bth —15t 13 qualifying samples taken, sample was below threshold
No qualifying discharges in January, February or March 1014. We will continue to monitor monthiy until we achieve 3 consecutive satisfactory results.
Any testing that can be Performed, will be performed, and reported os required.
7130114 Our Plant manager took Storm Water Samples on S/1SI14 during a flash flood. The plant had µ2.2" �f rain in 3 hours. The plant's runoff controls were not effective due primarily to
the volume. We have exceeded the TSS threshold by SOK We will continue to monitor and sample the outfall on at least a monthly basis until we achieve 3 consecutive samples within
specifications.

7 3Y14 Our Plant manager took Storm Water Samples on 5115114 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

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

If wastewater systems have not discharged in this quarter — report "No Flow" or "No Discharge" here. 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.
3 if 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.
° 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.

Due to 2 consecutive exceedances on our TSS levels during the the 10 and 2"dquarter 2013 we have instituted monthly monitoring until we achieve 3 consecutive samples
within normal TSS parameters. This facility is in low production:
Oct 8`h - IS` / 3 qualifyi g samples taken, sample was below threshold
No qualifyina discharges in January. Februa or March 2014. We will continue to monitor monthly until we achieve 3 consecutive sotisfactory results.
Any testing that can be performed will be_perfarmed and reported as required.
7I30/14 Our Plant manager took Storm Water Samples on 5/IS/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 SD%. We will continue to monitor and sample the outfall on at least a monthly basis until
we achieve 3 consecutive samples within specifications.
3'd Quarter 2014 - No qualifying discharges during the quarter
