Idaho Conservation League v. Wheeler, No. 18-1141 (D.C. Cir. 2019)Annotate this Case
The DC Circuit denied a petition for review challenging the EPA's February 2018 decision not to issue financial responsibility requirements for the hardrock mining industry. The court deferred to the EPA's interpretation that it should set financial responsibility regulations based on financial risks, not risks to health and the environment, because the use of "risk" in section 9608(b) in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), in the general mandate and amount clauses, was ambiguous and the EPA's interpretation was reasonable. Furthermore, nothing in section 9608(b) mandates the EPA to promulgate financial responsibility requirements for the hardrock mining industry, authorizing the EPA to decline to do so.
The court also held that the EPA's financial risk analysis and economic analysis were neither arbitrary nor capricious. Finally, under Circuit and Supreme Court precedent, the court held that the EPA's Final Action not to adopt financial responsibility requirements for the hardrock mining industry constitutes a logical outgrowth of the Proposed Rule.
