83 FR 6496 - Air Plan Approval; KY: Removal of Reliance on Reformulated Gasoline in the Kentucky Portion of the Cincinnati-Hamilton Area
GPO FDSys XML | Text Additional Documents ENVIRONMENTAL PROTECTION AGENCY Proposed rule. Comments must be received on or before March 7, 2018. 40 CFR Part 52 Summary The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted on September 13, 2017, by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ) in support of the Commonwealth's separate petition requesting that EPA remove the federal reformulated gasoline (RFG) requirements for Boone, Campbell, and Kenton counties in the Kentucky portion of the Cincinnati-Hamilton, Ohio-Kentucky-Indiana 2008 8-hr ozone maintenance area (hereinafter referred to as the “Northern Kentucky Area” or “Area”). The SIP revision revises the Commonwealth's maintenance plan emissions inventory and associated motor vehicle emissions budgets (MVEBs) to remove reliance on emissions reductions from the federal RFG program requirements; a program that the Commonwealth voluntarily opted into in 1995. The SIP revision also includes a non-interference demonstration evaluating whether removing reliance on the RFG requirements in the Northern Kentucky Area would interfere with the requirements of the Clean Air Act (CAA or Act). EPA is proposing to approve this SIP revision and the corresponding non-interference demonstration because EPA has preliminarily determined that the revision is consistent with the applicable provisions of the CAA.

GPO FDSys XML | Text Additional Documents ENVIRONMENTAL PROTECTION AGENCY Final rule. This final rule is effective on March 12, 2018. 40 CFR Part 52 Summary The Environmental Protection Agency (EPA) is approving state implementation plan (SIP) revisions submitted by the State of West Virginia. These revisions pertain to two West Virginia regulations that established trading programs under the Clean Air Interstate Rule (CAIR). The EPA-administered trading programs under CAIR were discontinued on December 31, 2014 upon the implementation of the Cross-State Air Pollution Rule (CSAPR), which was promulgated by EPA to replace CAIR. CSAPR established federal trading programs for sources in multiple states, including West Virginia, that replace the CAIR state and federal trading programs. The submitted SIP revisions request removal of state regulations that implemented the CAIR annual nitrogen oxide (NO X ) and annual sulfur dioxide (SO 2 ) trading programs from the West Virginia SIP (as CSAPR has replaced CAIR). EPA is approving these SIP revisions in accordance with the requirements of the Clean Air Act (CAA). West Virginia's SIP revision submittal requesting removal of a state regulation that implemented the CAIR ozone season NO X trading program will be addressed in a separate action.

The revisions to the SIP that EPA is proposing to approve pertain to changes to the District's air quality standards for fine particulate matter (PM 2.5 ) and ozone to reflect the 2012 PM 2.5 and 2015 ozone national ambient air quality standards (NAAQS). EPA is proposing to approve these portions of the SIP revisions because the Commonwealth has demonstrated that they are consistent with the Clean Air Act (CAA or Act). EPA will act on the other portions of the December 21, 2016, and August 29, 2017, submittals in a separate action.
83 FR 5594 - Air Plan Approval; AL; Section 128 Board Requirements for Infrastructure SIPs
GPO FDSys XML | Text Additional Documents ENVIRONMENTAL PROTECTION AGENCY Proposed rule. Comments must be received on or before March 12, 2018. 40 CFR Part 52 Summary The Environmental Protection Agency (EPA) is proposing 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. This submission addresses the Clean Air Act (CAA or Act) requirements applicable to Alabama state boards or agency personnel with respect to the approval of permits or enforcement orders. The submission also specifically addresses requirements for implementation of the following national ambient air quality standards (NAAQS): 1997, 2006, and 2012 Fine Particulate Matter (PM 2.5 ), 2008 8-hour Ozone, 2008 Lead, 2010 Nitrogen Dioxide (NO 2 ), and 2010 Sulfur Dioxide (SO 2 ). 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 proposed action, EPA is proposing to approve the October 24, 2017, submission with respect to: (1) The requirements applicable to state boards of the CAA; and (2) the related state board infrastructure SIP requirements for the 1997, 2006, and 2012 PM 2.5, 2008 8-hour Ozone, 2008 Lead, 2010 NO 2, and 2010 SO 2 NAAQS. In addition, EPA is proposing approval of ADEM's December 9, 2015, infrastructure SIP submission (as supplemented by the October 24, 2017 submission) related to the state board requirements for the 2012 PM 2.5 NAAQS. If this proposed approval action is finalized, EPA will no longer be required to promulgate a federal implementation plan (FIP) to address these CAA state board requirements for Alabama, as described in more detail below.

The interstate transport requirements under the CAA consist of several elements; this proposal pertains only to significant contribution to nonattainment and interference with maintenance of the NAAQS in other states. We are taking comments on this proposal and plan to follow with a final action.

83 FR 4847 - Air Plan Approval; Indiana; Regional Haze Five-Year Progress Report State Implementation Plan
GPO FDSys XML | Text Additional Documents ENVIRONMENTAL PROTECTION AGENCY Final rule. This final rule is effective on March 5, 2018. 40 CFR Part 52 Summary The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the state of Indiana on March 30, 2016. Indiana's SIP revision addresses requirements of the Clean Air Act (CAA) and EPA's rules that require states to submit periodic reports describing progress toward reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing regional haze SIP.

GPO FDSys XML | Text Additional Documents ENVIRONMENTAL PROTECTION AGENCY Interim final determination. This interim final determination is effective on January 10, 2018. However, comments will be accepted until February 9, 2018. 40 CFR Part 52 Summary The Environmental Protection Agency (EPA) is making an interim final determination that the State of Arizona has corrected a deficiency in its Clean Air Act (CAA or Act) state implementation plan (SIP) provisions concerning air permitting. Specifically, based on a proposed conditional approval published elsewhere in this Federal Register, and based on a prior proposed approval, previously published in the Federal Register, EPA is making an interim final determination that the State of Arizona (State) has satisfied the requirements of part D of the CAA permitting program for areas under the jurisdiction of the Arizona Department of Environmental Quality (ADEQ) with respect to fine particular matter (PM 2.5 ) precursors. The effect of this interim final determination that the State has corrected the deficiency in the permitting program is that the imposition of sanctions that were triggered by a previous limited disapproval action by EPA in 2016 is now deferred. If the State meets its commitment that is the basis for the conditional approval, relief from these sanctions will become permanent upon the EPA's full approval of the State submission. If the EPA determines that the State has not met its commitment and the conditional approval is converted to a disapproval, these sanctions will no longer be deferred.
