Summary
This EPA regulation (40 CFR Part 442) governs wastewater discharges from facilities that clean interiors of tanks used to transport chemical, petroleum, or food-grade cargos. It applies to tank trucks, rail tank cars, intermodal tank containers, tank barges, and ocean/sea tankers, but excludes exterior-only cleaning, drums/IBCs/closed-top hoppers, and facilities discharging under 100,000 gallons/year. The rule sets technology-based effluent limitations (BPT, BCT, BAT) for pollutants including BOD5, TSS, oil/grease, heavy metals (cadmium, chromium, copper, lead, mercury, nickel, zinc), and organics (fluoranthene, phenanthrene). It also includes pretreatment standards for POTW discharges and offers an alternative 'Pollution Prevention Allowable Discharge' path requiring a comprehensive Pollutant Management Plan with extensive documentation, waste segregation, recycling provisions, and recordkeeping.
Reason
This regulation imposes substantial hidden compliance costs on the tank cleaning industry through rigid technology mandates and bureaucratic planning requirements. The one-size-fits-all effluent standards disregard the specific circumstances and dispersed knowledge of individual operators, violating Hayek's critique of centralized planning. The Pollutant Management Plan requirement creates a significant administrative burden, particularly harming small businesses with limited resources. These costs are ultimately passed to consumers and create barriers to entry that protect incumbent firms from competition. The rule represents federal overreach into what state water quality standards and tort law could address more efficiently, with far greater flexibility and innovation. Americans are worse off bearing these $14,000+ per household in cumulative regulatory costs for marginal environmental benefits that could be achieved through less coercive means.
