Major point source pollution makes a major impact on a community. In 2010, the Pittsburgh Post-Gazette reported that Cheswick’s mortality rate was 87 percent over the national average with diseases linked to air pollution such as cardiovascular disease, COPD, and asthma. Allegheny County has some of the highest rates for asthma in the states and a growing number of cases in children.
Allegheny County currently violates federal safeguards for particulate and smog standards of the Clean Air Act.The Cheswick Power Plant is a source of nitrogen oxides and sulfur dioxide in the county. In 2013, the plant accounted for half of the nitrogen oxide pollution in the county and was the third largest contributor of fine particles. Upgrades at the plant to limit emissions have helped but Cheswick continues to rank among the highest polluters in the county.Though not a violation, the plant's sulfur output has almost tripled between 2013 and 2014, a worrisome trend.
There are limits to the amount of nitrogen oxides and sulfur dioxide that a power plant can emit. To meet those limits, plants can install and run pollution control technology or, in some cases, purchase credits to pollute. Currently, Cheswick’s permit allows the facility to emit unhealthy smog-forming pollution (NOx) at a rate that exceeds the capacity of the technology installed to control that pollution. Worse yet, the plant does not consistently run the pollution control technology that is installed onsite. This has contributed to the region’s ongoing elevated smog levels, which continue to violate federal safeguards.
The Title V permit for the Cheswick Power Plant expires at the end of 2015. These permits are required under the Clean Air Act to establish pollution limits for large emission sources. Environmental groups in the region are reaching out to the Allegheny County Health Department to strengthen the polluting limits of the plant. The permit will be drafted this summer and meetings will be held to collect public input.
