A district court denied a commercial fisherman's motion to preliminarily enjoin the Army Corps of Engineers and EPA from enforcing a 2023 rule that revised the definition of "waters of the United States." The fisherman argued the agencies did not faithfully implement the Sackett v. Environmental Pro...
The U.S. Supreme Court, 5-4, denied two states' motion to enter into a consent decree in a lawsuit concerning a 1938 interstate agreement that apportions the waters of the Rio Grande River among Colorado, New Mexico, and Texas. Texas initially sued Colorado and New Mexico, arguing excessive groundwa...
The U.S. Supreme Court, 5-4, granted three states' and several industry groups' applications to stay enforcement of EPA's 2023 rule issuing a federal implementation plan (FIP) for 23 states whose SIPs the Agency determined had failed to adequately address new air quality standards for ozone levels u...
Natural resource damages (NRD) under federal law is a statutory cause of action to compensate for injury to natural resources resulting from releases of hazardous substances or oil. Designated officials are authorized under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Oil Pollution Act (OPA), among others, to act as “trustees” on behalf of the public or tribes.
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) established the “Superfund,” which allows the U.S. Environmental Protection Agency (EPA) to clean up contaminated sites. It also forces the parties responsible for contamination to either perform cleanups or reimburse the government for the EPA-led cleanup work. The Superfund program relies on several tools to protect against lasting contamination.
On February 7, 2024, the U.S. Environmental Protection Agency (EPA) announced a final rule imposing a stricter limit for the fine particulate matter (PM2.5) national ambient air quality standard (NAAQS). The annual exposure standard for PM2.5, currently set at 12 micrograms per cubic meter of air, will now be 9 micrograms per cubic meter, marking the first time in over eight years that EPA has strengthened any NAAQS. The rule is predicted to have many health benefits, such as preventing 4,500 premature deaths by 2032, which may particularly affect overburdened communities.
The Ninth Circuit reversed in part summary judgment for the operators of a marine cargo terminal on Puget Sound in a CWA citizen suit concerning stormwater discharges. An environmental group argued the operators were liable for discharges from the facility's entire footprint, including an area known...
The D.C. Circuit rejected challenges to renewable fuels standards EPA set for 2020, 2021, and 2022. Cellulosic biofuel producers argued the standards were set too low, and petroleum refiners argued they were set too high. Specifically, the biofuel producers argued EPA misinterpreted or unreasonably ...
For more than half a century, the Chesapeake Bay and many of its tributaries have suffered from poor water quality. Compelled by an executive order and litigation, in 2010, the U.S. Environmental Protection Agency (EPA) issued the Chesapeake Bay total maximum daily load (Bay TMDL) to reduce pollution discharges and thereby restore Bay water quality; unfortunately, the Bay TMDL will fail to meet its 2025 objective.
The Third Circuit denied power companies' petition to review EPA's issuance of a federal implementation plan (FIP) establishing nitrogen oxide (NOx) emission limits for selective catalytic reduction-equipped coal-fired electric generating units in Pennsylvania to address reasonably available control...
