Hazardous Substances Tank Rule

EPA stated that it will have a proposed rule signed pertaining to regulation of hazardous substances under Clean Water Act (CWA) Section 311 by June 2018, and a final, court-mandated rule by 2019. The practical impact could be to expand EPA's Spill Prevention, Control and Countermeasure (SPCC) Rule to include tanks that contain “hazardous substances.” Facilities subject to the SPCC regulations must write and implement a plan certified by a registered professional engineer that effectively lays out how the facility operator will keep an oil spill from leaving the “four corners” of the facility.
