Rulemaking is the policy-making process for Executive and Independent agencies of the Federal government. Agencies use this process to develop and issue Rules (Rules are also referred to as “regulations”). The process is governed by the Administrative Procedure Act (APA) (5 U.S.C. Chapter 5) and can lead to a new Rule, an amendment to an existing Rule, or the repeal of an existing Rule. Executive Orders 12866, 13563, and 13579 also establish principles and guidance for the rulemaking process.
