Case Brief Summary & Legal Analysis
tl;dr: The court deferred to the EPA’s reasonable interpretation of its own ambiguous regulation defining “spent material.” A substance is “spent” once it can no longer serve its initial use, even if it has other potential uses, triggering hazardous waste regulations.
Legal Significance: This case reinforces the high deference courts grant to an agency’s reasonable interpretation of its own ambiguous regulations (Auer deference). It also affirms that published agency guidance can provide regulated parties with fair notice of an agency’s interpretation for due process purposes.

Case Facts & Court Holding
Key Facts & Case Background
Howmet Corporation used a potassium hydroxide (KOH) solution to clean metal castings. When the KOH became too contaminated for this initial purpose, Howmet sent the used, corrosive solution to Royster, a fertilizer manufacturer. Royster used the KOH as an ingredient in its fertilizer to control pH and provide potassium, without any processing. Howmet did not treat the shipments as hazardous waste under the Resource Conservation and Recovery Act (RCRA). The Environmental Protection Agency (EPA) brought an enforcement action, alleging the used KOH was a “solid waste” because it was a “spent material.” The regulatory definition of “spent material” is any material that “can no longer serve the purpose for which it was produced without processing.” 40 C.F.R. § 261.1(c)(1). Howmet argued that use in fertilizer was one of the fundamental purposes for which KOH was produced. The EPA contended the material became “spent” once it could no longer serve its initial use as a cleaning agent. The dispute centered on whether the EPA’s interpretation of its own regulation was permissible.
