Oliver E. Twaddell Explores Proposed EPA Drinking Water Regulations in CLM Magazine

Oliver E. Twaddell, partner in Goldberg Segalla’s Enviromental Law group, explored the potential impact of the EPA’s PFAS National Primary Drinking Water Regulation Rulemaking in an article in CLM Magazine.

The EPA’s proposed rules provide new regulations that would establish legally enforceable drinking-water levels for six per- and polyfluoroalkyl substances (PFAS) known to occur in drinking water and require maximum containment levels. Public water systems would then have to monitor PFAS, inform water consumers, install and maintain treatment technologies, perform recordkeeping and recording, and more in accordance with the regulations.

Communities would incur financial costs for the changes to public water systems that, while varying by state, would require stricter guidelines to drinking water than any existing regulations. There are additional concerns around the cost estimates in the proposed ruling, as it does not include costs of compliance with non-drinking water regulations that might follow the new drinking water limits.

Federal funding might be available for public water-system updates, but there will be a substantial cost to local and state governments.

“Although the proposed rule will be limited to public water systems, it will likely have economic repercussions across many industries that touch PFAS beyond just contamination areas, and not to mention potential federalism and state-level funding concerns,” Oliver said.

The proposed rules will be open for public comment until May 30.
