A federal appeals court has upheld the U.S. Environmental Protection Agency's (EPA) decision to let Oklahoma run federal environmental programs in parts of Indian country without a condition requiring the state to engage with tribes. In a 2–1 ruling on October 16 in Pawnee Nation of Oklahoma v. Zeldin, the Tenth Circuit held that the 2005 law behind the arrangement has not expired and that EPA cannot attach conditions to approvals under it.
How the Case Got Here
Section 10211 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act (SAFETEA) lets Oklahoma ask EPA to administer programs in Indian country. The state applied in July 2020, weeks after McGirt v. Oklahoma recognized much of eastern Oklahoma as reservation land, and EPA approved on October 1, 2020. After proposing to reconsider in 2021, EPA approved the request again on January 13, 2025, this time with a condition requiring Oklahoma to consult affected tribes. Earthjustice, the advocacy group representing the Pawnee Nation, had pushed for an outright denial and called the condition a compromise. On May 12, 2025, EPA issued a new approval without that condition, and the tribe sued.
Judge Timothy Tymkovich, joined by Judge Robert Bacharach, read the statute's mandatory approval language as leaving EPA no room to add conditions. Judge Richard Federico dissented, arguing that the canon protecting tribal sovereignty demanded a clearer statement from Congress before the state could take over.
What the Ruling Covers
The approval spans at least 26 programs under six federal laws, among them the Clean Air Act, the Clean Water Act, the Safe Drinking Water Act and the Resource Conservation and Recovery Act. Oklahoma's request excluded Indian allotments and tribal trust lands, so the regulator for a given site still depends on the land's legal status. Operators planning permits, renewals or expansions need that site-level check. Filing with the wrong regulator is the kind of facility compliance failure that no longer stays internal once it surfaces.
Buyers sourcing from Oklahoma plants face a related question. A valid state permit settles the legal one. It does not answer every community or environmental concern a procurement policy may cover, and those are often the risks standard supplier audits miss. Permit status, community engagement and emissions data each describe something different about a supplier, and none substitutes for the others in a Scope 3 or due diligence review. Elsewhere, Illinois lawmakers have moved to add environmental justice review to air permitting, which shows how differently states are handling the community side.
What Comes Next
The tribe's lawyer at Earthjustice called the outcome disappointing and said the Pawnee Nation is considering its next steps. Until a further appeal is filed and decided, the ruling stands and Oklahoma remains the administering authority for the covered programs.
