PRK for Repeal of Amendments to MATS (Mercury and Air Toxics) Rule

The proposed relaxation of regulations to reduce emissions of mercury and other hazardous and toxic ai pollutants from Electric Generating Units is a threat to the health, environment and lifeways of many Native communities throughout North America. The NTAA has consistently supported the application of available control technologies for minimizing emissions of these contaminants from existing coal -and oil-fired power plants – among the largest sources of these pollutants.

Cost-effective technological developments and growth of renewable energy industries have resulted in significantly reduced emissions of mercury and toxic metals from fossil fuel combustion. The current regulations pursuant to Section 112 of the Clean Air Act are necessary to continue emissions reductions.

The proposed repeal of these regulations ignores the continuing impacts of airborne mercury and multiple toxic metals. Comments on this proposed rule are due to EPA by August 11, 2025, using the Federal Rulemaking Portal via https://www.regulations.gov/ or by email: a-and-r-docket@epa.gov, Attn. Docket ID No. EPA-HQ-OAR- EPA-HQ-OAR-2018-0794
