The Minnesota Pollution Control Agency (MPCA) has adopted amendments to rules governing air quality, Minnesota Rules chapters 7002, 7005, 7007, 7009, 7011, 7017, and 7019. The new rules update these chapters to keep Minnesota’s air quality rules current and ensure consistency with applicable state and federal regulations. The rules also implement the Minnesota Legislature’s 2020 ban on the use of trichloroethylene (TCE). Rule-related documents are provided below.
The new rules are effective May 2, 2022.

This rulemaking, referred to as the Air Quality Housekeeping Rule (R-04678), is part of an ongoing effort to maintain and improve the MPCA’s existing rules. The overall purpose of the rulemaking is to keep the air quality rules current, ensure consistency with applicable federal and state regulations, clarify ambiguous rule language, and correct gaps or errors identified while administering the rules. This rulemaking is needed to maintain the delegation from the U.S. Environmental Protection Agency (EPA) to implement and enforce certain provisions of the Clean Air Act in Minnesota, including the Title V operating permit program.
The rule amendments, as proposed, are summarized below.
Housekeeping rules. Various rule updates are necessary to account for changes in federal rules, to clarify existing language, and ease overall understanding of the rules. This includes:
- Updating requirements for Part 70 permit application notice and comment, and updating procedures to petition for EPA review of state and Part 70 permits.
- Modifying general requirements for Option B, C, and D registration permits and capped permits.
- Incorporating by reference federal plan requirements for small municipal waste combustor units and municipal solid waste landfills.
- Other minor housekeeping rule changes to clarify definitions, correct gaps and errors identified while administering the rules, and align state and federal rules.
New trichloroethylene (TCE) rule. The 2020 Minnesota Legislature enacted a ban on the use of TCE through the air quality permitting program. The MPCA intends to adopt a rule to implement the ban.
