Requires agencies to publish advance notice of proposed rulemaking for major rules and for high-impact rules (rules having an annual cost on the economy of $100 million or $1 billion or more, respectively), which shall include a written statement identifying the nature and significance of the problem the agency may address with a rule, the legal authority under which the rule may be proposed, and a solicitation for written data and comments from interested persons.

Sets forth criteria for issuing major guidance (agency guidance that is likely to lead to an annual cost on the economy of $100 million or more, a major increase in cost or prices, or significant adverse effects on competition, employment, investment, productivity, innovation, or ability to compete).

Expands the scope of judicial review of agency rulemaking by allowing immediate review of rulemaking not in compliance with notice requirements and establishing a substantial evidence standard for affirming agency rulemaking decisions.

(Sec. 3) Revises procedures for rulemaking under the Administrative Procedure Act (APA) to require a federal agency, in the rulemaking process, to make all preliminary and final factual determinations based on evidence and to consider: (1) the legal authority under which a rule may be proposed, (2) the specific nature and significance of the problem the agency may address with a rule, (3) whether existing rules have created or contributed to the problem the agency may address with a rule and whether such rules may be amended or rescinded, (4) any reasonable alternatives for a new rule, and (5) the potential costs and benefits associated with potential alternative rules.

Revises rulemaking notice requirements to require an agency to: (1) publish in the Federal Register advance notice of proposed rulemaking involving a major or high-impact rule that involves a novel legal or policy issue arising out of statutory mandates; (2) consult with the Administrator of the Office of Information and Regulatory Affairs of the Office of Management and Budget (OMB) before issuing a proposed rule and after the issuance of an advance notice of proposed rulemaking; (3) provide interested persons an opportunity to participate in the rulemaking process; (4) hold a hearing before the adoption of any high-impact rule; (5) expand requirements for the adoption of a final rule, including requiring that the agency adopt a rule only on the basis of the best evidence and at the least cost; and (6) grant any interested person the right to petition for the issuance, amendment, or repeal of a rule.  Specifies the minimum amount of information that must be included in an advance notice.

Requires the Administrator to issue guidelines to promote coordination, simplification, and harmonization of agency rules during the rulemaking process

Exempts from such revised procedures rulemakings that concern monetary policy proposed or implemented by the Board of Governors of the Federal Reserve System or the Federal Open Market Committee.

(Sec. 4) Imposes new requirements for issuing any major guidance or guidance that involves a novel legal or policy issue arising out of statutory mandates. Authorizes the Administrator to issue guidelines for agencies in issuing major guidance or other guidance.

(Sec. 5) Provides for electronic access to transcripts of testimony and exhibits and other papers filed in a rulemaking proceeding.

Requires the record of decision in a rulemaking proceeding to include information from a hearing under the Information Quality Act or on a high-impact rule.

Requires an agency to grant a petition for a hearing in the case of a major rule, unless the agency reasonably determines that a hearing would not advance consideration of the rule or would unreasonably delay completion of the rulemaking. Exempts from this requirement rulemakings that concern monetary policy proposed or implemented by the Board of Governors of the Federal Reserve System or the Federal Open Market Committee.

(Sec. 6) Provides that an agency's denial of an Information Quality Act petition, or a failure to grant or deny such petition within 90 days, is reviewable by a court as a final action.  Allows immediate judicial review of interim rules, other than in cases involving national security interests, issued without compliance with the notice requirements of this Act.

(Sec. 7) Revises standards for the scope of judicial review of agency rulemaking to prohibit a court from deferring to an agency's: (1) interpretation of a rule if the agency did not comply with APA requirements, (2) determination of the costs and benefits or other economic or risk assessment if the agency failed to conform to guidelines on such determinations and assessments established by the Administrator, (3) determinations made in the adoption of an interim rule, or (4) guidance.

(Sec. 8) Defines "substantial evidence" for purposes of evaluating agency adjudications and for rulemaking under APA as such relevant evidence as a reasonable mind might accept as adequate to support a conclusion in light of the record considered as a whole, taking into account whatever in the record fairly detracts from the weight of the evidence relied upon by the agency to support its decision.

(Sec. 9) Provides that the amendments made by this Act to specified provisions of federal law shall not apply to any rule makings pending or completed on the enactment date of this Act.
