What it's about

The Supreme Court overturned the Ninth Circuit and sent the case back (reversed and remanded), ruling that the EPA’s reasonable reading of the rule then in force exempted those discharges from permits.

EPA changed the Industrial Stormwater Rule during the dispute, but the older version governed the discharges already at issue.

Question presented

1. Do the runoff ditches and channels constitute "point sources" that require permits? 2. Are the petitioners exempt from the permit requirement?

What the Court decided

Holding

1. A provision of the Act governing challenges to agency actions, §1369(b), is not a jurisdictional bar to this suit. That provision is the exclusive vehicle for suits seeking to invalidate certain agency decisions, such as the establishment of effluent standards and the issuance of permits. It does not bar a district court from entertaining a citizen suit under §1365 when the suit is against an alleged violator and seeks to enforce an obligation imposed by the Act or its regulations. The present action falls within the scope of §1365. 2. The EPA’s recent amendment to the Industrial Stormwater Rule does not make the cases moot. A live controversy continues to exist regarding whether petitioners may be held liable for unlawful discharges under the earlier version of the Industrial Stormwater Rule. That version governed petitioners’ past discharges, which might be the basis for the imposition of penalties even if, in the future, those types of discharges will not require a permit. These cases thus remain live and justiciable. See Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Foundation, Inc., 484 U. S. 49, 64–65. 3. The preamendment version of the Industrial Stormwater Rule, as permissibly construed by the EPA, exempts discharges of chan - neled stormwater runoff from logging roads from the NPDES permitting scheme. The regulation is a reasonable interpretation of the statutory term “associated with industrial activity,” §1342(p)(2)(B), and the agency has construed the regulation to exempt the discharges at issue here. 640 F. 3d 1063, reversed and remanded.

Result
Reversed

The Court's reasoning

The Court said the Clean Water Act’s provision for reviewing agency decisions did not bar a lawsuit to enforce the Act against alleged violators. It also found EPA’s reading of the earlier stormwater rule reasonable: it exempted these logging-road discharges from permits.

From the opinions

“The Court there gives effect to a reading of EPA’s regulations that is not the most natural one, simply because EPA says that it believes the unnatural reading is right.”

— Justice Antonin Scalia(dissent)
