"The supplemental proposal was submitted on Monday and will be released with a final repeal of Biden-era rules."
"The White House is reviewing a new proposal to permanently end EPA’s regulation of power plants’ carbon emissions.
What happened: The supplemental proposal entered White House review on Monday, according to the Office of Management and Budget’s website. It is expected to be released along with another rule to undo 2024 standards that required coal-fired and some new gas-fired power plants to capture and store most of their greenhouse gas emissions.
EPA did not immediately respond to a request for comment.
Why it matters: The draft would repeal not only the Biden-era rules, but EPA’s broader authority to regulate climate pollution from the power sector via the Clean Air Act. The power industry is the largest industrial source of greenhouse gas emissions in the U.S.
The proposal is expected to mirror EPA’s repeal of the so-called endangerment finding. But it could also complicate arguments the oil industry and the Justice Department are making in a landmark case before the Supreme Court this fall that the Clean Air Act makes EPA the “primary regulator” of industrial greenhouse gas emissions."
