Ozone Pollution

Action on Clean Air Act Section 126 Petitions from Delaware and Maryland

EPA has denied four petitions submitted by Delaware and one petition from Maryland requesting reductions in emissions of ozone-forming nitrogen dioxide from specific power plants in upwind states - Indiana, Kentucky, Ohio, Pennsylvania and West Virginia. To reach this decision, EPA looked at whether there are current and future nonattainment or maintenance problems for the 2008 and/or 2015 ozone air quality standards in the petitioning states. EPA also looked at whether there were additional cost-effective emission control measures available for the named sources. EPA found that existing programs that require cost effective emissions reductions from all of the named sources, such as the recent CSAPR Update Rule, are in place and will address the concerns of the petitioning states.
