Air pollution control rules

Pine grosbeak and blue sky

Wisconsin's State Legislature creates and revises the Wisconsin Statutes (Wis. Stats.), while state agencies such as the DNR create and revise the rules required and authorized by those statutes. These agency rules constitute the Wisconsin Administrative Code (Wis. Adm. Code).

Federal law

Many air pollution control requirements in state statutes and rules reflect mandates contained in the Federal Clean Air Act [exit DNR]. Also under the Clean Air Act, the U.S. Environmental Protection Agency (EPA) created federal regulations that Wisconsin air pollution control rules must reflect.

Proposed rules

Public participation is a critical component of agency rulemaking and we value your involvement in DNR's rulemaking activities. There are numerous opportunities for you to participate in the DNR rulemaking process.

Current rules

The table belows lists all current Wisconsin air pollution control rules.
