This subpart applies to discharges resulting from the cleaning of tank trucks, intermodal tank containers, rail tank cars, tank barges and ocean/sea tankers which have been used to transport food grade cargos. If wastewater generated from cleaning tanks used to transport food grade cargos is mixed with wastewater resulting from cleaning tanks used to transport chemical or petroleum cargos, then the combined wastewater is subject to the provisions established for the corresponding tanks (i.e., truck, railcar or barge) in subparts A, B, or C of this part.
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 BPT:

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 & grease (HEM) and pH are the same as the corresponding limitation specified in § 442.41.
Any new point source subject to this subpart must achieve the following performance standards: Standards for BOD5, TSS, oil and grease (HEM) and pH are the same as the corresponding limitation specified in § 442.41.
