Notice of proposed rulemaking
A notice of proposed rulemaking (NPRM) is a public notice that is issued by law when a U.S. federal agency wishes to add, remove, or change a rule or regulation as part of the rulemaking process. The notice is an important part of US administrative law, which facilitates government by typically creating a process of taking of public comment.
