State agencies; require simultaneous repeal of two existing rules whenever proposed new rule takes effect.

HB 401 requires Mississippi state agencies to identify at least two existing rules for repeal whenever they propose adopting a new rule. This applies directly to all state agencies creating new regulations, mandating that the repeal of those two rules occurs simultaneously with the new rule's effective date. Key mechanisms include requiring agencies to list the repealed rules in their rule-making docket, notice of proposed rule adoption, and economic impact statements. The bill aims to streamline regulations by ensuring new rules don't accumulate without removing outdated ones.
