Wyoming coal plants can keep emitting the same amount of haze for now

US environmental regulators approved Wyoming's plan to control haze from the Jim Bridger coal power plant. The plan allows the plant's first two units to continue emitting the same amount of nitrogen oxides as before. This means the plant does not have to install new pollution controls for these units right away.

The Clean Air Act requires states to reduce regional haze, often by forcing older coal plants to upgrade their pollution controls. This approval means Wyoming's Jim Bridger plant avoids those upgrades for its first two units, at least for this round of planning. It effectively maintains the status quo for these specific emissions, rather than tightening them.
