The House Armed Services Committee has passed legislation that would set several new requirements for how the Defense Department (DOD) addresses per- and polyfluoroalkyl substances (PFAS), including a measure to force it to comply with state drinking water and groundwater requirements unless they are weaker than any federal level.

EPA Administrator Andrew Wheeler says the agency is preparing to swiftly roll out a slate of international work to cut ozone-depleting emissions, wastewater pollution and ocean debris under the newly implemented U.S.-Mexico-Canada Agreement (USMCA), including release of $300 million in one-time funds for high-impact projects.

The full U.S. Court of Appeals for the District of Columbia Circuit in a sweeping decision is curbing the Federal Energy Regulatory Commission’s (FERC) use of “tolling orders” that it has long used to delay administrative reconsideration of natural gas infrastructure approvals and subsequent lawsuits over those projects.

Air pollution experts fear EPA’s proposed rule outlining changes to cost-benefit reviews for air policies would preclude counting a variety of important health-related benefits from emissions cuts, while exacerbating prior critiques of the agency’s recent scientific review for ozone that downplayed the certainty of such health harms.

Environmentalists and California-aligned states in fresh legal and administrative filings are detailing a host of new and existing critiques of the Trump administration’s rollback of vehicle greenhouse gas standards, including a new argument that the rule’s already meager claimed benefits evaporate due to flawed assessments of traffic congestion.

California regulators are rejecting for now an industry coalition’s chemical “alternatives analysis” for spray polyurethane foam (SPF) products containing unreacted methylene diphenyl diisocyanates (MDI), which have been listed as “priority products” for review under the state’s Safer Consumer Products (SCP) green chemistry program.

Intensifying their strong opposition to draft California air rules to significantly tighten emission standards for a variety of lawn, garden and other outdoor equipment, industry groups argue the rule would fail to meet criteria to obtain a Clean Air Act preemption waiver from EPA, which the state needs to adopt and enforce new standards.
