Trump Moves to Curb State Power Over Waterway Permits to Fast-Track Energy and AI Projects

The Trump administration has proposed a new rule that would limit the ability of U.S. states and tribes to block or delay major energy and infrastructure projects over water quality concerns, a move the Environmental Protection Agency (EPA) says is designed to speed permitting for energy development and artificial intelligence–related infrastructure.

The proposal would revise a 2023 Biden-era rule interpreting Section 401 of the Clean Water Act, which restored broad authority for states and tribes to review and potentially halt federally permitted projects such as pipelines, power plants and transmission lines. That rule had replaced a narrower Trump-era framework that constrained state oversight.

EPA officials argue the Biden rule created uncertainty and prolonged approval timelines. Jess Kramer, EPA assistant administrator for water, said the 2023 framework was “inefficient and ineffective,” leading to delays that hindered infrastructure development.

The proposed revision would introduce standardized procedures and firm timelines for state and tribal water quality certifications, which Kramer said would deliver predictable permitting and “unleash American energy dominance” while supporting fast-growing AI infrastructure needs.

Environmental groups and conservation advocates strongly criticized the proposal, warning it could weaken protections for rivers, wetlands and drinking water sources. Cathy Collentine of the Sierra Club said the move risks allowing fossil fuel projects to pollute waterways with fewer checks, putting public health and vulnerable communities at risk.

EPA officials counter that the rule would prevent Section 401 from being used as a political tool to block projects unrelated to water quality impacts. The proposal continues the administration’s broader rollback of Biden-era environmental regulations while prioritizing fossil fuel development and grid expansion.

The rule will be open for a 30-day public comment period, with the EPA aiming to finalize it in the spring.

Federal-state waterway-permit conflict adds another layer of legal uncertainty for energy, AI and infrastructure projects, and it will surface as litigation and community pushback well before any single project actually moves.
