HB 4386 Summary

• Removes restrictions on state agencies adopting rules more stringent than federal standards by deleting subsections (8), (9), and (10) from MCL 24.232, which previously required director approval for exceeding federal mandates.

• Establishes that guidelines, operational memoranda, bulletins, and interpretive statements are non-enforceable and merely advisory, and cannot be used by agencies or courts to support decisions subject to judicial review.

• Requires agencies to submit proposed rules electronically to the legislative service bureau for formal certification within 21 calendar days, with provisions for tolling if rules are returned for revision.

• Mandates comprehensive regulatory impact statements including comparisons to federal standards, cost-benefit analyses, identification of affected parties, and documentation of efforts to reduce disproportionate impact on small businesses.

• Requires agencies to transmit regulatory impact statements to the legislature at least 28 days before public hearings and publish them on agency websites at least 10 days before hearings, with legislative fiscal agencies analyzing fiscal implications.
