Under the terms of the Administrative Procedure Act (APA), an NPRM is the step where the regulatory agency shares its actual intended regulation and asks for public comment. An NPRM must contain “(1) the time, place, and nature of public rulemaking proceedings; (2) reference to the legal authority under which the rule is proposed; and (3) either the terms or substance of the proposed rule or a description of the subjects and issues involved.” Prior to publishing an NPRM in the Federal Register, a regulatory agency may first publish an ANPRM. At every stage, public comments are requested.
