Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the application of BCT: Limitations for BOD5, TSS, oil and grease (HEM) and pH are the same as the corresponding limitation specified in § 442.31.
Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the application of BAT: Limitations for cadmium, chromium, copper, lead, mercury, nickel, and zinc are the same as the corresponding limitation specified in § 442.31.
Any new point source subject to this subpart must achieve the following performance standards: Standards for BOD5, TSS, oil and grease (HEM), cadmium, chromium, copper, lead, mercury, nickel, zinc and pH are the same as the corresponding limitation specified in § 442.31.
Except as provided in 40 CFR 403.7 and 403.13, any existing source subject to this subpart must achieve the following pretreatment standards:
