On May 25, 2023, after more than 15 years of fighting, a couple contesting the Environmental Protection Agency’s assertion of jurisdiction over their residential lot as “waters of the United States” (WOTUS) under the Clean Water Act (CWA) scored a decisive victory in a U.S. Supreme Court decision, Sackett v. EPA. Chantell and Mike…

Last week EPA released its proposal for the first set of Maximum Contaminant Levels (MCLs) under the Clean Water Act for per- and polyfluoroalkyl substances (PFAS).  In contrast to non-enforceable health advisory levels introduced in 2016 and revised in 2022, MCLs constitute enforceable drinking water standards that will impact drinking water utilities and industry nationwide. …

In a 50-year game of ping-pong, the Biden administration marked the end of 2022 by taking its turn revising the definition of “waters of the United States,” or “WOTUS” for short. This term determines where Clean Water Act (CWA) permits are required for wetland dredging and filling and pollutant discharges, as well as other CWA…

The Standells may “love that dirty water” according to their 1966 hit song, but the Environmental Protection Agency’s (EPA) New England region is hoping to reduce stormwater pollution running off industrial, commercial and institutional properties “down by the banks of the river Charles” and throughout three Boston area watersheds. After prodding from the Conservation…

On April 6, 2022, by a 5-4 vote in the case of Louisiana, et. al. v. American Rivers, et. al., the Supreme Court temporarily resurrected a Trump-era rule that sought to stop the practice of many states and tribes from withholding or unduly conditioning their certifications that are required under the Clean Water Act…

This post is part of an ongoing series covering the Biden administration’s efforts pursuant to Executive Order 13990 to repeal and replace regulations adopted during the Trump administration. Prior posts include Catching Up on the 2021 Clean Water Act Releases.

The Council on Environmental Quality (CEQ) recently issued a Notice of Proposed Rulemaking to…

The latest season of Clean Water Act (CWA) changes are now streaming from the courts and federal agencies. The Biden administration and lower courts have picked up where prior administrations and the U.S. Supreme Court left off, as we reported last year in Binge-Watching the Clean Water Act Cases and Rules. Unless Congress somehow finds bipartisan support for legislative fixes, we expect contentious CWA rulemaking proceedings to resume and protracted CWA litigation to prosper. These actions constrain land developers, utilities and companies with projects or operations that impact wetlands or other water features. These decisions might also give environmental groups and agencies stronger grounds on which to base CWA claims targeting sewers, pipelines, tanks, and other systems that leak or seep wastes into groundwater.

As we previously reported, EPA published a PFAS Action Plan in 2019 designed to enhance and improve data gathering, regulatory development, enforcement, and communication related to per- and polyfluoroalkyl substances (PFAS). EPA continues to make progress implementing the PFAS Action Plan and is working on a more formal framework for addressing PFAS under the…
