s 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 area. 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.
