Approval and Promulgation of Air Quality Implementation Plans; Arkansas; Infrastructure State Implementation Plan Requirements for the National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Arkansas to address the requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 2006 and 2012 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS), 2008 lead (Pb) NAAQS, 2008 ozone (O3) NAAQS, 2010 nitrogen dioxide (NO2) NAAQS, and the 2010 sulfur dioxide (SO2) NAAQS. Under CAA sections 110(a)(1) and 110(a)(2), each state is required to submit a SIP that provides for the implementation, maintenance, and enforcement of a revised primary or secondary NAAQS. CAA section 110(a)(1) and (2) require each state to make a new SIP submission within three years after EPA promulgates a new or revised NAAQS for approval into the existing SIP to assure that the SIP meets the applicable requirements for such new and revised NAAQS. This type of SIP submission is commonly referred to as an ``infrastructure SIP or ``i-SIP.'' We propose approval of this action under Section 110 of the Act.
Air Plan Approval; Delaware; State Implementation Plan for Interstate Transport for the 2008 Ozone Standard; Withdrawal of Direct Final Rule
Due to adverse comments received, the Environmental Protection Agency (EPA) is withdrawing the September 27, 2017 direct final rule that approved a revision to the Delaware state implementation plan (SIP) related to the interstate transport of air pollution for the 2008 ozone national ambient air quality standards (NAAQS). EPA stated in the direct final rule that if EPA received adverse comments by October 27, 2017, the rule would be withdrawn and not take effect. EPA subsequently received adverse comments. EPA will address the comments received in a subsequent final rulemaking action based upon the proposed approval action for the same SIP submittal which was also published on September 27, 2017. EPA will not institute a second comment period on this action.
State of Iowa; Withdrawal of Direct Final Rule; Elements of the Infrastructure SIP Requirements for the 2012 Annual Fine Particulate Matter (PM2.5
Due to an adverse comment, the Environmental Protection Agency (EPA) is withdrawing the direct final rule for ``Approval of Implementation Plans; State of Iowa; Elements of the Infrastructure SIP Requirements for the 2012 Annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standard (NAAQS)'' published in the Federal Register on September 29, 2017. Infrastructure SIPs address the applicable requirements of Clean Air Act (CAA) section 110, which requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by the EPA. These SIPs are commonly referred to as ``infrastructure'' SIPs. 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 under the CAA.
Approval and Promulgation of Air Quality Implementation Plans; Virginia; Removal of Clean Air Interstate Rule (CAIR) Trading Programs; Withdrawal of Direct Final Rule
Due to receipt of an adverse comment, the Environmental Protection Agency (EPA) is withdrawing the September 28, 2017 direct final rule (DFR) that approved a revision to the Virginia state implementation plan (SIP). The revision removed from the Virginia SIP regulations from the Virginia Administrative Code that established EPA- administered trading programs under the Clean Air Interstate Rule (CAIR), which were discontinued on December 31, 2014 upon the implementation of the Cross-State Air Pollution Rule (CSAPR). EPA stated in the direct final rule that if EPA received adverse comments by October 30, 2017, the rule would be withdrawn and not take effect. EPA subsequently received an adverse comment. EPA will address the comments received in a subsequent final action based upon the proposed action also published on September 28, 2017. EPA will not institute a second comment period on this action.
