Proposed Rulemaking—E15 Fuel Dispenser Labeling and Compatibility with Underground Storage Tanks
EPA’s Administrator signed a notice of proposed rulemaking regarding E15 labeling on fuel dispensers and UST system compatibility provisions.
About the UST system compatibility section of the proposed rulemaking
EPA proposed revisions to the 2015 UST regulation. Specifically, EPA proposed to grant certain allowances for owners and operators in demonstrating compatibility, making it easier for them to meet the current requirements. EPA also proposed a new requirement that in the future when UST systems are installed, or UST equipment and components are replaced, they must be constructed with equipment and components that are compatible with ethanol blends up to 100 percent; this requirement would be effective within one year of the effective date of the final rule.
EPA proposed to change the 2015 state program approval regulation and make it consistent with the proposed revisions of the compatibility requirements in the 2015 UST regulation. These rule changes, if finalized, would be effective in states without state program approval and in Indian Country. In all other states and territories, the states and territories would have three years from the final rule date to update their regulations as part of their state program approval.
