The EPA document dismantling the 2024 power plant standards

The document is public and fully readable on the website of the US Environmental Protection Agency: it is the preamble to the rule signed by Administrator Lee Zeldin on September 14, 2026 (EPA). We read it because it contains two different things put together, and the difference between the two almost always disappears in the retelling.

1. What it says

The first part is a final rule: the agency finalizes the repeal of most of the requirements contained in the Carbon Pollution Standards of 2024, that is, the set of obligations on power plant emissions adopted two years ago. Here there is nothing left to decide: the repeal is formalized.

The second part is a supplemental notice of proposed rulemaking. The agency proposes — verb in the present tense, effect suspended — the repeal of the 2015 endangerment findings and related rules governing greenhouse gas emissions from fossil fuel-fired power plants. A proposal follows a path: comments, hearing, possible subsequent final rule.

Of this path the document already sets out one small but revealing element: the public hearing will be held virtually and grants each participant four minutes of oral testimony. It is the concrete measure of how much space, in the process, is given to the voice of those who want to speak rather than write.

2. The limits the text declares on its own

This is not a study, so there is no sample, method or conflicts of interest to disclose. The limits are of a different nature and lie in the structure of the rule itself. The first: the agency writes “most” of the requirements, not all — the document does not eliminate the entire 2024 framework, and which part survives is a matter to be read article by article. The second: the larger portion of the action, the one concerning the 2015 findings, is at the proposal stage and may change or never reach a conclusion. The third: a regulatory action of this scope is normally headed for litigation, and a preamble does not contain its own resilience in court.

3. What a summary loses

The decision was picked up by the press: the US edition of EL PAÍS dedicated an article to it dated September 15, 2026. Of this text our dossier records the existence and the date, not excerpts: for this reason we do not summarize its content and simply flag it as a second source.

What a brief summary hardly contains is the double track. Those who stop at the summary conclude that everything has already been cancelled; the document says that one part is cancelled and another is under consultation, with a hearing still to be held. In the first case the matter is closed, in the second there is an open procedure in which local governments, businesses and organizations can file comments. This is not a nuance for lawyers only: it changes whether there is still something to be done or not.

4. Why it matters

The rules on power plant emissions concern facilities that generate electricity by burning fossil fuels, that is, one of the main sources of greenhouse gases in an industrial economy. Repealing them does not produce one more emission the next day: it removes a future constraint on investment, and industrial plans in the electricity sector are written on long horizons.

The next verifiable step is procedural: the virtual public hearing set out in the document, with four minutes per speaker, and the subsequent possible final rule on the part still at the proposal stage.
