Air Plan Approval; AL; Section 128 Board Requirements for Infrastructure SIPs
The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) submission, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), on October 24, 2017, and a portion of a December 9, 2015, infrastructure SIP submission. The October 24, 2017 submission addresses the general Clean Air Act (CAA or Act) conflict of interest requirements applicable to Alabama state boards or agency personnel with respect to the approval of permits or enforcement orders. This submission also specifically addresses requirements for implementation of the following national ambient air quality standards (NAAQS): 1997, 2006, and 2012 Fine Particulate Matter (PM2.5), 2008 8-hour Ozone, 2008 Lead, 2010 Nitrogen Dioxide (NO2), and 2010 Sulfur Dioxide (SO2). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA. Whenever EPA promulgates a new or revised NAAQS, the CAA requires the state to make a new SIP submission establishing that the existing SIP meets the various applicable requirements, or revising the SIP to meet those requirements. This type of SIP submission is commonly referred to as an ``infrastructure'' SIP. In this action, EPA is approving the October 24, 2017, submission with respect to: The CAA conflict of interest requirements; and the related conflict of interest infrastructure SIP requirements for the 1997, 2006, and 2012 PM2.5, 2008 8-hour Ozone, 2008 Lead, 2010 NO2, and 2010 SO2 NAAQS. In addition, EPA is approving a portion of ADEM's December 9, 2015, infrastructure SIP submission (as supplemented by the October 24, 2017 submission) related to the conflict of interest requirements for the 2012 PM2.5 NAAQS. This action removes EPA's obligation to promulgate a Federal Implementation Plan (FIP) to address these CAA state board requirements for Alabama.
