Last week, District Judge Susan Mollway ruled that the County of Maui must obtain a NPDES permit for discharges to groundwater by the Lahaina Wastewater Reclamation Facility.  It is the first trial court decision applying the factors identified by Justice Breyer in the SCOTUS Maui decision. 

Judge Mollway found the most important factors to be what she considered to be the relative short distance from the discharge to the surface water (½ mile) and the relatively short time between the groundwater discharge and the surface water discharge (as little as 84 days and,… More

The Supreme Court ruled today that discharges to groundwater are subject to the permitting requirements of the Clean Water Act, but only where the “discharge is the functional equivalent of a direct discharge from the point source into navigable waters.”

I don’t often say this about Supreme Court environmental decisions, but I think that the Court got it exactly right.

The apparent dilemma for the Court was that,… More

Yesterday, Judge William Young ruled that discharges to groundwater are not subject to Clean Water Act jurisdiction, even if they ultimately reach surface waters that are unambiguously waters of the United States.  He did not wade into the murky waters, as it were, of the Maui case or any of the various judicial theories for or against jurisdiction.  Instead, he took a simpler path.… More

On Monday, EPA issued an Interpretive Statement concluding that point source discharges to groundwater are never subject to NPDES permitting requirements.  EPA did a good job marshalling its arguments – much better than this EPA has done in a number of similar situations.

I have previously noted the difficulties associated with regulating point source discharges to groundwater under the NPDES program,… More

The Sixth Circuit ruled earlier this week that discharges to groundwater are not subject to Clean Water Act jurisdiction.  We now have the requisite circuit split, opening the possibility of Supreme Court review.  For those who might still be open-minded, I commend both the majority and dissenting opinions in the 6th Circuit; they are each as clear and as persuasive as they could be.

Although I have long thought that it does not make sense to regulate discharges to groundwater under the CWA,… More

Last week, the 4th Circuit Court of Appeals – not the most liberal court in the land – joined the 9th Circuit in ruling that discharges from a point source to groundwater can be subject to the Clean Water Act.  The decisions follow a number of district court cases to the same effect.  It’s hard to deny the trend at this point.  

I’ve always been skeptical of these cases,… More

As I’ve previously discussed, whether a discharge to groundwater may be subject to Clean Water Act jurisdiction is currently in dispute.  Now the 9th Circuit has weighed in, finding that point discharges to groundwater are subject to the Clean Water Act, so long as an ultimate discharge of pollutants to surface waters of the United States is “fairly traceable” to the discharge to groundwater. … More

Whether the Clean Water Act regulates discharges to groundwater has been a topic of significant debate.  At this point, there seems to be something of a trend in the cases towards concluding it does, but it remains true that all of the courts of appeal that have addressed the issue have concluded that it does not.  As I have noted, the problem with the “yes” answer is that pretty much all groundwater eventually discharges to surface water,… More

The Clean Water Act regulates discharges of pollutants to waters of the United States.  That term is not understood to include groundwater.  The Sierra Club was unhappy about alleged discharges to groundwater from coal ash disposal facilities at the Chesapeake Energy Center power plant.  The plant had a solid waste permit for the disposal facilities under Virginia law and, one can at least infer, was in compliance with the solid waste permit.… More

Daily Environment Report today noted that the National Research Council has produced a study, Alternatives for Managing the Nation’s Complex Contaminated Groundwater Sites, which assesses the scope of the groundwater contamination problem and our ability to address it. One significant takeaway from the report is that

Significant limitations with currently available remedial technologies persist that make achievement of MCLs throughout the aquifer unlikely at most complex groundwater sites in a time frame of 50-100 years.… More
