ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 442 Effluent Limitations Guidelines, Pretreatment Standards, and New Source Performance Standards for the Transportation Equipment Cleaning Point Source Category AGENCY: Environmental Protection Agency (EPA). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: This regulation establishes technology-based effluent limitations guidelines, new source performance standards, and pretreatment standards for the discharge of pollutants into waters of the United States and into publicly owned treatment works (POTWs) by existing and new facilities that perform transportation equipment cleaning operations. Transportation equipment cleaning (TEC) facilities are defined as those facilities that generate wastewater from cleaning the interior of tank trucks, closed-top hopper trucks, rail tank cars, closed-top hopper rail cars, intermodal tank containers, tank barges, closed-top hopper barges, and ocean/sea tankers used to transport materials or cargos that come into direct contact with the tank or container interior. Facilities which do not engage in cleaning the interior of tanks are not considered within the scope of this rule. EPA is subcategorizing the TEC Point Source Category into the
For all four subparts, EPA is establishing effluent limitations guidelines for existing facilities and new sources discharging wastewater directly to surface waters. EPA is establishing pretreatment standards for existing facilities and new sources discharging wastewater to POTWs in all subparts except for Subpart D, applicable to Food Grade Cargos. EPA is not establishing effluent limitations guidelines or pretreatment standards for facilities that generate wastewater from cleaning the interior of hopper cars. The TEC limitations do not apply to wastewaters associated with
The wastewater flows covered by this rule include all washwaters
