Benefits and Costs of the Clean Air Act

Cross-State Air Pollution Rule in Massachusetts

While sources in Massachusetts are not required to make reductions under the Cross-State Air Pollution Rule (CSAPR), this rule will help ensure that Massachusetts families aren't suffering the consequences of harmful air pollution generated far from home. Facilities have until March 1, 2013 to demonstrate compliance with the rule, which slashes millions of tons of smokestack pollution that can lead to premature death, heart attacks, bronchitis and asthma.  

Carried long distances across the country by wind and weather, power plant emissions of sulfur dioxide (SO2) and nitrogen oxide (NOx) continually travel across state lines. As the pollution is transported, it reacts in the atmosphere and contributes to harmful levels of smog (ground-level ozone) and soot (fine particles), which are scientifically linked to widespread illnesses and premature deaths and prevent many cities and communities from enjoying healthy air quality.

With this rule in place, EPA is ensuring that future generations will have access to clean air and all the benefits that come along with healthy, vibrant communities.

Health Benefits in Massachusetts in 2014

  • The CSAPR will improve air quality in Massachusetts, providing the state with important public health benefits, including up to 390 fewer premature deaths each year.
  • The states total health benefits as a result of the final rule will be between $1.3 billion and $3.2 billion each year.
