The Reg Map is based on general requirements. In some cases, more stringent or less stringent requirements are imposed by statutory provisions that are agency specific or subject matter specific. Also, in some cases more stringent requirements are imposed by agency policy.
In a typical case, a rulemaking action would proceed from step one through step nine with a proposed rule and a final rule.
However, if a rulemaking action is exempt from the proposed rulemaking procedures under the Administrative Procedure Act provisions (explained under step three) or under other statutory authority, an agency may:
promulgate a final rule omitting steps three through six, or
promulgate an interim final rule omitting steps three through six, but providing a comment period and a final rule after step nine.
Also, if an agency determines that a rule likely would not generate adverse comment, the agency may promulgate a direct final rule, omitting steps three through six, but with a duty to withdraw the rule if the agency receives adverse comments within the period specified by the agency.
