Section 304.216  Newton Station Suspended Solids Discharges

The limitation on the discharge of total suspended solids (TSS) in Section 304.124(a) does not apply to the discharge from the ash pond system of Illinois Power Generation Company's Newton Station, located in Jasper County.  Instead, Illinois Power Generation Company’s ash pond system discharge must not exceed 30 mg/L monthly average and 50 mg/L daily composite for TSS, and 15 mg/L monthly average and 30 mg/L daily composite for non-volatile TSS. The definitions of Section 304.104(b) apply to these effluent limits.
