The Environmental Protection Agency (EPA) is proposing to approve most elements of State Implementation Plan (SIP) submissions from Massachusetts regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 1997 ozone, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO<INF>2</INF>), and 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). EPA is also proposing to conditionally approve three aspects of the Commonwealth's submittals. In addition, we are also proposing findings of failure to submit pertaining to various aspects of the prevention of significant deterioration (PSD) requirements of infrastructure SIPs. Lastly, we are proposing to remove 40 CFR 52.1160 as legally obsolete. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.
