The Environmental Protection Agency (EPA) is proposing to approve most elements of a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts for the infrastructure requirements for the 2012 fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS), including the interstate transport requirements. We are proposing findings of failure to submit for the prevention of significant deterioration (PSD) requirements of infrastructure SIPs for the 2012 PM<INF>2.5</INF> NAAQS. We are also proposing several actions related to infrastructure SIP requirements for the 1997 and 2006 PM<INF>2.5</INF> NAAQS, including approvals for previously unaddressed elements and converting certain previous conditional approvals to full approval. We are also proposing to convert to full approvals previous conditional approvals for the 1997 and 2008 ozone, 2008 lead, 2010 sulfur dioxide, and 2010 nitrogen dioxide NAAQS. Finally, EPA is proposing to approve five new or amended definitions regarding the NAAQS and Particulate Matter and a state Executive Order regarding consultation by state agencies with local governments. This action is being taken under the Clean Air Act.
