Analyzed Economic Effects
5 provisions identified: 5 benefits, 0 costs, 0 mixed.
New Enforcement Petition Rights for Regulated Parties
If DOT starts an enforcement action against you, you can petition the DOT General Counsel to claim the Department violated these procedural protections. Possible remedies include removing the enforcement team from the matter, excluding certain evidence or issues, or restarting the enforcement action; the General Counsel has discretion whether to review petitions or grant relief. These enforcement-rights provisions take effect May 27, 2026.
Higher Standards for Big Cost Rulemakings
DOT treats 'economically significant' rulemakings as those with annualized U.S. costs of $100,000,000 or more or a net loss of at least 75,000 full-time jobs over 5 years, and 'high-impact' rulemakings as those with $500,000,000 or more or a net loss of at least 250,000 jobs over 5 years. These costly rulemakings must follow enhanced procedures, including either an Advance Notice of Proposed Rulemaking (ANPRM) or a Supplemental Notice of Proposed Rulemaking (SNPRM).
Ten-for-One Regulatory Offset Requirement
For each new significant regulation DOT issues, the Department will identify at least 10 existing regulatory burdens for revocation, consistent with Executive Order 14192. This is part of DOT's regulatory policy to limit unnecessary regulatory burden.
Guidance Must Include Cost Assessments
Before issuing guidance documents, DOT now requires a good-faith cost assessment of the guidance's economic impact on regulated parties. Guidance must also be reviewed legally and written in plain language, and if it goes beyond existing law it must clearly state it does not have the force of law.
Minimum Comment Period for Significant Guidance
For significant DOT guidance documents, the rule requires at least a 30-day public comment period before issuance, except where notice and comment are impracticable or contrary to the public interest. DOT may provide longer comment periods when appropriate.
