### AGENCY: Environmental Protection Agency (EPA) . ACTION

: Proposed rule. SUMMARY: Under Clean Air Act section 112(1), EPA may approve state or local rules or programs to be implemented and enforced in place of certain otherwise applicable Federal rules, emissions standards, or requirements . EPA proposes to approve Rhode Island Department of Environmental Management's ("RI DEM's") request for approval to implement and enforce Air Pollution Control Regulation Number 36, Control of Emissions fromOrganic Solvent Cleaning ("RI Regulation No. 36") and Rhode Island Air Pollution Control, General Definitions Regulation ("RI General Definitions Rule"), as a partial substitution for the National Emissions Standards for Halogenated Solvent Cleaning ("Halogenated Solvent NESHAP") as it applies to organic solvent cleaning machines in Rhode Island, except for continuous webcleaning machines. This approval would grant RI DEM

the authority to implement and enforce RI Regulation No. 36 and the RI General Definitions Rule in place of the Halogenated Solvent NESHAP for organic solvent cleaning machines and would make the Rhode Island Department of Environmental Management's rules referenced above federally enforceable. Continuous web cleaning machines would remain subject to the Halogenated Solvent NESHAP.DATES: Written comments must be received on or before [Insert date 30 days from
