The Environmental Protection Agency (EPA) is proposing to approve revisions to Pennsylvania's state implementation plan (SIP) to implement reasonably available control technology (RACT) for major sources of nitrogen oxides (NOX) and volatile organic compounds (VOC). These changes are aimed at reducing ozone pollution under the 1997 and 2008 national air quality standards. Pennsylvania submitted these revisions to establish RACT for eight specific sources out of the nine initially proposed. This proposal is part of efforts to ensure cleaner air and better public health by meeting federal Clean Air Act requirements.
Simple Explanation
The EPA wants to make the air cleaner in Pennsylvania by making factories use special tools that help stop bad chemicals from going into the air. This is like making sure you wash your hands to keep germs away.
