Regulations.gov is your source for all regulations (or rulemakings) issued by U.S. government agencies. Regulations.gov includes regulations that are open for public comment (i.e., proposed) and closed for comment (i.e., final). Regulations.gov also includes other non-rulemaking documents, such as Federal agency notices, supporting materials, public comments, and Federal agency guidance and adjudications. Regulations.gov is therefore your one-stop source to find and view all Federal regulations and related materials. Through Regulations.gov you may also comment on proposed regulations open for comment and related documents.
