American Mining Congress v. EPA
Citation and Court
965 F.2d 759 (D.C. Cir. 1993)
Facts
The Environmental Protection Agency issued guidance documents interpreting the Resource Conservation and Recovery Act’s definition of “solid waste” as it applied to recycled materials generated by the mining industry. The American Mining Congress challenged the guidance as a legislative rule requiring notice-and-comment rulemaking under the APA.
Issue
Whether EPA’s guidance documents constituted legislative (substantive) rules requiring APA notice-and-comment procedures, or interpretive rules exempt from those requirements.
Holding
The guidance documents were interpretive rules, not legislative rules, because EPA had not relied on them as having the force of law to determine rights or obligations independent of the underlying statute; interpretive rules are exempt from notice-and-comment rulemaking.
Rule / Doctrine
A rule is legislative (requiring notice-and-comment) if the agency intends it to have the force of law — to bind private parties or the agency itself with legal consequences beyond what the statute alone requires. An interpretive rule merely clarifies the agency’s reading of an existing statute or regulation and does not independently alter legal rights; it is exempt from APA § 553 notice-and-comment requirements.
Significance
American Mining Congress v. EPA is a leading D.C. Circuit case defining the interpretive rule / legislative rule distinction, a critically important boundary in administrative law because it determines whether agencies must go through the time-consuming APA rulemaking process before issuing policy guidance.
