FL S1670

Requires agencies to prepare statements of estimated regulatory costs before adopting or amending most rules, with expanded definitions of what constitutes adverse impact on small businesses and detailed cost calculation requirements.

Creates a new "repromulgation" process requiring agencies to review and republish existing rules every 5-10 years without substantive changes, with automatic repeal of rules not repromulgated by deadline.

Expands public participation in rulemaking by requiring agencies to gather information for cost statements at public workshops, making persons responsible for preparing cost statements available at hearings, and allowing electronic delivery of advance notices to interested persons.

Requires agencies to file petitions to initiate rulemaking with the Administrative Procedures Committee and extends timelines for rule adoption when lower-cost regulatory alternatives are proposed.

Modifies rulemaking procedures by requiring material incorporated by reference to be publicly accessible, tolling deadlines during separate proceedings, and increasing transparency through website publication of full regulatory cost statements.
