A preamble is a discussion that provides detailed information about the background, purpose, justification, and technological feasibility of a proposed or final rule. It precedes the regulatory text when the rule is published in the Federal Register. The preamble for a proposed rule provides information about the reason for the rule and the alternatives the Agency is considering. It asks the public to provide information, data, opinions, and concerns to assist the Agency in making decisions about the rule. The preamble for a final rule contains a discussion of the comments that the Agency received concerning the proposed rule and describes how the Agency addresses these comments in the final rule.
