PM2.5 National Ambient Air Quality Standards (NAAQS) State Implementation Plan (SIP) Requirements Rule (Renewal)

The EPA has established a suite of PM2.5 standards based on numerous health studies and other evidence demonstrating that serious health effects are associated with exposure to elevated levels of PM2.5. Estimates show that attainment of the PM2.5 standards would result in tens of thousands fewer premature deaths each year, tens of thousands fewer hospital admissions each year, and hundreds of thousands fewer doctor visits, absences from work and school, and respiratory illnesses in children annually. EPA initially established annual and 24-hour PM2.5 standards in 1997. The 24-hour standard was subsequently revised in 2006, and the primary annual standard was revised in 2012. The EPA finalized the PM2.5 NAAQS State Implementation Plan (SIP) Requirements Rule (81 FR 58010) effective October 24, 2016, to describe the Clean Air Act (CAA) requirements that must be met by states with nonattainment areas to develop plans for attaining and maintaining the NAAQS. The intended effect of the PM2.5 NAAQS SIP Requirements Rule is to provide certainty to states regarding their planning obligations related to SIP development. Only states with nonattainment areas are required to submit SIPs that meet the requirements of the rule. The information collection activities in this proposed renewal have been submitted for approval to the Office of Management and Budget (OMB) under the Paperwork Reduction Act (PRA). The PRA requires the EPA to assess the administrative burden (in hours and dollars) for state air agencies to develop plans to attain the PM2.5 NAAQS, and for EPA to review and take action on such plans.
