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.

Are Discharges to Groundwater Potentially Subject to the Clean Water Act? A Circuit Split Tees It Up.
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
Who Knew? The National Research Council Discovers That Many Groundwater Cleanups Will Take More Than 100 Years
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
