A multistate coalition of state attorneys general has filed suit over the Trump administration's repeal of climate regulations for U.S. power plants, The New York Times reported this week.

The complaint targets the regulatory rollback rescinding greenhouse gas performance standards that governed new and existing coal- and gas-fired electricity generating units. The underlying rule had obligated plant operators to deploy carbon capture and sequestration, co-fire with lower-carbon fuels, or commit to retirement timelines — the operating envelope that drove utility capital planning across the U.S. generation fleet through the late 2020s.

The New York Times headline identifying the suit did not list the plaintiff states, the filing venue, or the docket number; the publication's full report is expected to carry those specifics. Multistate challenges to Environmental Protection Agency deregulatory actions customarily proceed through the U.S. District Court for the District of Columbia or the U.S. Court of Appeals for the D.C. Circuit.

What the action covers

The repealed regulation established binding greenhouse gas performance rates for generating units, set subcategory standards for baseload versus intermediate-load operation, and defined state-plan obligations flowing from Clean Air Act Section 111. Its removal returns the federal regulatory baseline for new-build permitting and existing-source compliance to conditions that pre-date the climate rule's effective period.

State attorneys general in prior climate cases have invoked the "arbitrary and capricious" standard of Section 706(2)(A) of the Administrative Procedure Act, arguing EPA exceeded its statutory discretion or shortchanged the record supporting rescission. Parallel challenges to vehicle greenhouse gas standards have produced mixed outcomes at the appellate level, with the U.S. Supreme Court granting review in one matter and remanding others.

Why recyclers and waste managers are tracking it

The repeal carries second-order consequences for the materials stream. Power plants are the leading industrial generator of coal-combustion residuals (CCR); the regulatory framing of climate rules has shaped how much coal ash utilities have economic incentive to beneficially reuse — substituting for Portland cement in concrete — versus dispose in lined impoundments. A vacated rule removes the planning signal that justified retrofits at marginally profitable plants and tilts reuse economics toward landfill.

It also intersects with the waste-to-energy pipeline. Refuse-derived fuel, solid recovered fuel pellets, and tire-derived fuel burn in cement kilns and dedicated energy-from-waste facilities, whose relative carbon profile against coal and natural gas determines whether the streams count under state renewable portfolio standards. Every revision of the federal climate rule resets that comparison.

What happens next

Docket assignment and any motion for preliminary relief will define the pace. If the court grants expedited review, briefing compresses from a multi-month window to weeks. Either way, utilities planning capacity additions through the remainder of the decade will price the legal uncertainty into integrated resource plans and long-term fuel procurement contracts. The next material event will be the agency's filing of the administrative record — typically 90 to 180 days after a complaint — or any cross-motions filed in the interim.

Recyclers, cement kiln operators, and ash marketers will read the same docket for the same reason: the regulatory perimeter that decides how much of the nation's most carbon-intensive generation stream either retires, retrofits, or competes with waste-derived fuel substitutes through the remainder of the decade.
