EPA announced today that it is proposing to list PFOA and PFAS as hazardous substances under CERCLA. EPA appears to be sanguine about how the listing will play out in the real world. 
EPA is focused on holding responsible those who have manufactured and released significant amounts of PFOA and PFOS into the environment. EPA will use enforcement discretion and other approaches to ensure fairness for minor parties who may have been inadvertently impacted by the contamination.… More
Last Friday, the D.C. Circuit Court of Appeals vacated EPA’s rule adding the West Vermont Drinking Water Contamination Site to the National Priorities List, finding EPA’s decision to be arbitrary and capricious and not supported by substantial evidence. 
As the opinion makes clear, EPA has to work pretty hard to lose these cases.

Earlier this week, the Massachusetts DEP issued a package of regulatory reforms. While the focus of the package was on finding ways for MassDEP to implement its mission with fewer resources, a number of the reforms are specifically targeted at facilitating the development of renewable energy. If you want to see more about that angle, you can take a look at our client alert about the reforms.… More
As I have previously mentioned, EPA is considering including criteria related to vapor intrusion (VI) in the hazard ranking system scoring used to determine which sites should be added to the National Priorities List. As I noted when this first became news, it’s pretty much an obvious step for EPA to take. These are precisely the types of sites on which EPA should be focusing. At a certain level,… More
Vapor intrusion is the issue de jour at federal and state Superfund sites. On the federal side, EPA announced in January that it was considering adding vapor intrusion criteria to its calculation of hazard ranking scores. Frankly, as a concept, it’s hard to dispute. In fact, aside from when actual public water supplies are contaminated, indoor air is probably about the only risk associated with Superfund sites that we should care about. Every analysis EPA has ever done has shown that risks associated with Superfund sites are otherwise overestimated and it is not a cost-effective place to be putting environmental protection dollars. The question of course is how to go about regulating indoor air.… More
