The basic process by which all federal agencies typically develop and issue regulations is set forth in the Administrative Procedure Act (APA)2 and is generally known as the rulemaking process. Rulemaking at most regulatory agencies follows the APA's informal rulemaking process, also known as "notice and comment" rulemaking, which generally requires agencies to publish a notice of proposed rulemaking in the Federal Register, provide interested persons an opportunity to comment on the proposed regulation, and publish the final regulation, among other things.
