Andrew Wheeler, who ran the EPA during the Trump administration, told E&E News that the demise of the Chevron doctrine would require the Biden administration to rewrite the EPA's new power plant rule that requires fossil fuel-fired power plants to reduce emissions by 90%.

If Friday's ruling is the chess-equivalent of check for the Biden EPA regulations, then a second Trump term would be checkmate.
