Administrative LawClean Water ActRulemakingJudicial ReviewAPAClean Water ActEPAplacer mining

Facts

EPA promulgated effluent-limitation guidelines and standards for placer mining, including BPT limits based on simple settling, BAT limits and new-source standards based on recirculation technology, and five BMPs to control mine drainage and infiltration. The regulations were aimed at controlling discharge of process wastewater from gold placer mining, which occurs in or near streams and can increase solids and toxic metals in receiving waters. Petitioners challenged EPA's authority to regulate placer mining, the adequacy of notice-and-comment procedures, the merits and factual basis of the limitations, the new-source criteria, the availability of variances, the timing of compliance, and the constitutionality of the rule. EPA also solicited additional comment on impacts to small mines and ultimately declined to modify the rule.

Issue

Whether EPA's placer-mining regulations under the Clean Water Act exceeded EPA's statutory authority, were promulgated without adequate notice and comment, or were otherwise arbitrary, capricious, procedurally invalid, untimely, or unconstitutional. The case also asked whether placer mining discharges are subject to the Clean Water Act and whether the challenged limitations and standards were lawfully supported.

Rule

Under the APA, EPA regulations must be upheld unless they are arbitrary, capricious, an abuse of discretion, contrary to law, in excess of statutory authority, or adopted without required procedure. Courts owe great deference to EPA's reasonable interpretation of the Clean Water Act, especially where the Agency reconciles competing policies within its expertise. In notice-and-comment rulemaking, a final rule may differ from the proposal so long as the final provision is in character with the original proposal and is a logical outgrowth of the notice and comments received; minor errors do not justify setting aside the rule absent prejudicial harm.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Oregon, Cascade Hollow Minerals uses a floating washing system in a creek to separate platinum flakes from gravel dredged from the creek bed. The system returns the disturbed sediment-laden water to the same creek through a discharge pipe. In a rulemaking, a federal environmental agency interprets the Act's term "addition" to include redeposit or resuspension of creek-bed material.

If Cascade Hollow challenges the rule on the ground that it adds nothing from outside the creek, how should a reviewing court most likely rule?

Explanation. The majority held that the agency acted within its authority in treating redeposit or resuspension of streambed material as an "addition" of pollutants and that courts should defer to that reasonable interpretation of the Clean Water Act. A court therefore would likely reject the operator's argument that same-source sediment categorically falls outside the statute. (Derived from Rybachek v. Environmental Protection Agency (n.d.).)
