Air pollution from power plants is linked to asthma, heart attacks—and thousands of premature deaths each year.
The EPA's first-ever nationwide protections to clean up air emissions from power plants—The Mercury & Air Toxics Standards—will avert long term environmental and public health damage. Read main feature
Number of Power Plants Likely Covered by the Mercury & Air Toxics Standards. Power plants have been exempted from the Clean Air Act for decades.
About this Map
Facilities on this map have been identified by the U.S. Environmental Protection Agency as power plants likely covered by the Mercury & Air Toxics Standards (MATS) for Power Plants.
- Facilities lacking latitude and longitude coordinates are included in the state summary totals, but are not placed as data points on this map.
- Data points of very closely neighboring facilities may partially or completely overlap each other.
- Facilities in Guam and Puerto Rico have not been included in this map.

EPA's complete description of the data:
This file contains facilities that are included in the NEEDS [National Electric Energy Data System] 4.10 MATS data base and that contain at least one oil-fired steam generating unit or one coal-fired steam generating unit that generates more than 25 megawatts of power. This includes coal-fired units that burn petroleum coke and that turn coal into gas before burning (using integrated gasification combined cycle or IGCC).
NEEDS reflects available capacity on-line by the end of 2011; this includes committed new builds and committed retirements of old units.
Only coal and oil-fired units are covered by this rule. Some of the oil units contained in this file are capable of burning oil and/or gas. If a unit burns only gas, it will not be covered in the rule.
Power Plants Likely Covered by the Toxics Rule Outside the Contiguous U.S.: IPM modeling did not include generation outside the contiguous U.S., where EPA is aware of only two facilities that would be subject to the coal-fired requirements of the final rule. Given the limited number of potentially impacted facilities, limited availability of input data to inform the modeling, and limited connection to the continental grid, EPA did not model the impacts of the rule beyond the contiguous U.S. These facilities data are based on EPA's Information Collection Request (ICR) for New and Existing Coal- And Oil-Fired Electric Utility Stream Generation Units.
