The administration finalized rules that:
- Regulates carbon dioxide emissions from existing coal and new gas plants
-
Tightens limits for coal plants’ releases of toxic metals into the air by 67 percent and making some plants reduce their mercury emissions
- Reduces coal plants’ discharges of toxic metals via wastewater
- Adds new requirements for long defunct plants’ legacy coal ash ponds to prevent waste leakage
The climate rule is expected to prevent 1.38 billion metric tons of carbon emissions through 2047, the equivalent of taking 328 million gas-powered cars off the road for a year.
Combined with investments in climate-friendly power sources from the Democrats’ Inflation Reduction Act, the rule could help bring the power sector’s carbon dioxide emissions down by 62 percent below where they were in 2022 by 2035, the administration said.
The rule requires coal and new gas plants to either use carbon capture to reduce their emissions by 90 percent — or achieve equivalent emissions reductions by other means.
A proposed version of the rule also applied limitations to existing natural gas plants — but those were stripped from the final version. The EPA says it will try to tackle them at a later date.
Compared to the proposed rule, the new rule gives coal plants two extra years before they have to meet the requirements, but makes new gas plants apply them three years more quickly.
