ANPRM -- An Advance Notice of Proposed Rulemaking is a preliminary notice, published in the Federal Register, announcing that an agency is considering a regulatory action. The agency issues an ANPRM before it develops a detailed proposed rule. The ANPRM describes the general area that may be subject to regulation and usually asks for public comment on the issues and options being discussed. An ANPRM is issued only when an agency believes it needs to gather more information before proceeding to a notice of proposed rulemaking.

CFR -- The Code of Federal Regulations is an annual codification of the general and permanent regulations published in the Federal Register by the departments and agencies of the Federal Government.

RFA -- A Regulatory Flexibility Analysis is a description and analysis of the impact of a rule on small entities, including small businesses, small governmental jurisdictions, and certain small not-for-profit organizations. The Regulatory Flexibility Ac t (5 U.S.C. 601) requires each agency to prepare an initial RFA for public comment when it is required to publish an NPRM and to make available a final RFA when the final rule is published, unless the agency head certifies that the rule would not have a significant economic impact on a substantial number of small entities.

RIN -- The Regulation Identifier Number is assigned by the Regulatory Information Service Center to identify each regulatory action listed in the Unified Agenda and The Regulatory Plan, as directed by Executive Order 12866 (section 4(b)).

Seq. No. -- The Sequence Number identifies the location of an entry in the printed edition of the Unified Agenda and The Regulatory Plan appearing in the Federal Register. Note that a specific regulatory action will have the same RIN throughout its development, but will generally have different sequence numbers in different editions of the Unified Agenda and The Regulatory Plan.
