US environmental regulators propose to loosen pollution rules for coal plants

The US environmental regulators want to undo recent changes that tightened pollution limits for coal and oil-fired power plants. This means older, dirtier plants might not have to upgrade their equipment as quickly or as much as previously planned.

The US environmental regulators are proposing to roll back stricter limits on hazardous air pollutants from power plants. This move could allow some coal and oil-fired plants to continue operating with less stringent pollution controls than they would have faced under the recently updated rules. It also signals a potential shift in how the agency approaches regulating emissions from these facilities.
