The EPA is granting the Rhode Island Department of Environmental Management (RI DEM) the authority to implement and enforce the amended Rhode Island Code of Regulations, Control of Emissions from Organic Solvent Cleaning (Organic Solvent Cleaning Rule), and the General Definitions Regulation (General Definitions Rule) in place of the National Emission Standard for Halogenated Solvent Cleaning (Halogenated Solvent NESHAP) as a partial rule substitution as it applies to organic solvent cleaning machines in Rhode Island.

The Environmental Protection Agency (EPA) is proposing to approve a Clean Air Act (CAA) plan and two state rules submitted by the Missouri Department of Natural Resources (MoDNR) on July 25, 2022. This plan was submitted to fulfill the state's obligations under the CAA to implement and enforce the requirements of the Emissions Guidelines and Compliance Times for municipal solid waste (MSW) landfills. This plan includes an inventory of affected sources and explains how the state rules fulfill the regulatory requirements needed for EPA to approve the plan.

This action proposes changes to the EPA's Air Emissions Reporting Requirements (AERR). The proposed amendments may require changes to current regulations of State, local, and certain tribal air agencies; would require these agencies to report emissions data to the EPA using different approaches from current requirements; and would require owners/operators of some facilities to report additional emissions data.

The Environmental Protection Agency (EPA) is removing the ``emergency'' affirmative defense provisions from the EPA's title V operating permit program regulations. These provisions established an affirmative defense that sources could have asserted in enforcement cases brought for noncompliance with technology-based emission limitations in operating permits, provided that the exceedances occurred due to qualifying emergency circumstances.
