Conversely, power plants that cannot meet this standard must plan to cease operations by 2039, a year earlier than previously proposed. The EPA also broadened the operational scope of new natural gas plants, redefining baseload plants to include those operating at or above a 40% capacity factor.
EPA Unveils Final Power Plant Rules : Advancing Mercury and Toxics Standards
The updated Mercury and Air Toxics Standards (MATS) rule mandates a substantial reduction in mercury emissions from lignite coal-fired plants by 70% and a 67% decrease in filterable particulate matter emissions. These changes are expected to concurrently lower nickel, arsenic, and other hazardous pollutants, reinforcing the EPA’s commitment to public health and environmental safety.
Wastewater and Coal Ash Management Enhancements
Another pivotal rule revision will see coal-fired power plants cut pollutants in wastewater by over 660 million pounds annually. The enhanced Effluent Limitations Guidelines and Standards aim to significantly reduce the presence of toxic metals like mercury, arsenic, and selenium.
