Rule
Summary
The EPA is giving a thumbs-up to Minnesota’s updated air rules that make state and federal standards match up better. This change mainly affects small air pollution sources by clarifying their permit rules and adding some new exempt categories. The new rules kick in on December 22, 2025, with no extra costs expected for businesses or the state.
Analyzed Economic Effects
4 provisions identified: 4 benefits, 0 costs, 0 mixed.
Four New Exempt Source Categories
Minnesota added four categories of conditionally exempt small sources—auto-body refinishing (7008.2300), coating facilities (7008.2400), woodworking facilities (7008.2500), and an insignificant facility technical standard (7008.2600). These additions are incorporated into the Minnesota SIP and take effect on December 22, 2025.
Permit Rules Clarified for Small Sources
Minnesota revised permit rules and clarified permit requirements for small sources of air emissions (chapters including 7007 and 7008), and EPA approved those changes into the SIP. The revisions are federally effective on December 22, 2025.
State Rules Now Federally Enforceable
EPA incorporated Minnesota's adopted rule sections by reference into the State Implementation Plan, making those state rules federally enforceable under Clean Air Act sections 110 and 113 as of December 22, 2025.
No Application on Indian Reservation Lands
The Minnesota SIP approval does not apply on any Indian reservation land or in areas where a Tribe has jurisdiction. EPA states the action will not impose substantial direct costs on Tribal governments or preempt Tribal law.
