Air Plan Approval; New Hampshire; Infrastructure State Implementation Plan Requirements for the 2012 PM2.5

The Environmental Protection Agency (EPA) is proposing to approve elements of two State Implementation Plan (SIP) submissions from New Hampshire which address the infrastructure and interstate transport requirements of the Clean Air Act (CAA or Act) for the 2012 fine particle (PM2.5) National Ambient Air Quality Standards (NAAQS). 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. This action is being taken under the Clean Air Act.
