Department of Environment, Great Lakes and Energy EGLE intended to address all applicable infrastructure requirements for the 2015 ozone NAAQS. EPA is disapproving the portion of the submission pertaining to the visibility protection requirements of section 110a2DiII with respect to the 2015 ozone NAAQS. The disapproval portion of this action does not begin a new FIP clock, because the FIPs are already in place. EPA will take action in a separate rulemaking on the portion of the submission pertaining to the interstate transport requirements of section 110a2DiI with respect to the 2015 ozone NAAQS.
Whenever EPA promulgates a new or revised NAAQS, CAA section 110a1
requires states to make SIP submissions to provide for the implementation, maintenance, and enforcement of the NAAQS. This type of SIP submission is commonly referred to as an infrastructure SIP. These submissions must meet the various requirements of CAA section 110a2, as applicable.
Due to ambiguity in some of the language of CAA section 110a2, EPA
believes that it is appropriate to interpret these provisions in the specific context of acting on infrastructure SIP
submissions. EPA has previously provided comprehensive guidance on the application of these provisions through our September 13, 2013
Infrastructure SIP Guidance and through regional actions on infrastructure submissions EPAs 2013 Guidance.1
Unless otherwise noted below, we are following that existing approach in acting on this submission. In addition, in the context of acting on such infrastructure submissions, EPA
evaluates the submitting states SIP for facial compliance with statutory and regulatory requirements, not for the states implementation of its SIP.2 EPA
has other authority to address any issues concerning a states implementation of the rules, regulations, consent orders, etc. that comprise its SIP.
1 EPA explains and elaborates on these ambiguities and its approach to address them in our September 13, 2013 Infrastructure SIP Guidance available at https www3.epa.gov/airquality/
urbanair/sipstatus/docs/Guidance_on_
Infrastructure_SIP_Elements_Multipollutant_
FINAL_Sept_2013.pdf, as well as in numerous agency actions, including EPAs prior action on Minnesotas infrastructure SIP to address the 2008
ozone, 2010 nitrogen dioxide NO2, 2010 sulfur dioxide SO2, and 2012 fine particulate matter PM2.5 NAAQS 80 FR 63436 October 20, 2015.
