Fourteen Months Later And Still Waiting For Any Court To Apply SCOTUS's Maui Functional Equivalence Test

In April of 2020, Justice Breyer, delivering the Supreme Court's opinion in Maui v. Hawaii Wildlife Fund,  told us that "the traditional common-law method, making decisions that provide examples that in turn lead to ever more refined principles" would, over time, define the reach of the Clean Water Act.  Today Lara Beaven, of Inside EPA,  reports that fourteen months later we're still waiting.   

One of the first post-Maui  decisions was anticipated to come from the Seventh Circuit in Prairie Rivers Network v. Dynegy Midwest Generation,  a citizen suit alleging that releases from coal ash ponds to groundwater were prohibited by the Clean Water Act.  Before Maui,  the District Court, applying pre-Maui  Seventh Circuit precedent, held that the Clean Water Act did not apply to such releases.  On appeal Dynegy argued for the first time that the Prairie Rivers Network hadn't established standing to sue and the three Judge panel agreed.

So it is back to square one for Prairie Rivers Network and Dynegy.  Prairie Rivers Network will amend its complaint and "the traditional common law method" that Justice Breyer lauded in Maui  will start all over again in that case.

And, as Ms. Beaven reports, it is now most likely that the first post-Maui  application of the Supreme Court's functional equivalence test will be in the Maui  case.  A trial is scheduled in the fall.

In the meantime, EPA is beginning its eighth attempt to tackle the same question tackled by the Supreme Court, more cases are filed, and confusion continues to reign.
