Summary

The Environmental Protection Agency (EPA) is proposing to approve most elements of a State Implementation Plan (SIP) submission from Rhode Island that addresses the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS). We are also proposing to conditionally approve certain elements of this submittal that relate to requirements for the state's Prevention of Significant Deterioration (PSD) program. In addition, EPA is proposing to disapprove the submission with respect to future SIP revisions. However, a federal implementation plan has been in place for this requirement since 1973. 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 with respect to this NAAQS under the CAA.
