Partial Approval and Partial Disapproval of Attainment Plan for the Idaho Portion of the Logan, Utah/Idaho PM2.5
The Environmental Protection Agency (EPA) is taking final action on portions of a state implementation plan (SIP) submission from the State of Idaho. The SIP submission addresses attainment plan requirements for the Idaho portion of the Logan, Utah-Idaho nonattainment area (Logan UT-ID) for the 2006 24-hour PM2.5 National Ambient Air Quality Standards (NAAQS). The Idaho Department of Environmental Quality (IDEQ) submitted the attainment plan to the EPA on December 14, 2012 (2012 SIP submission), and supplemented the attainment plan on December 24, 2014 (2014 amendment). The EPA is approving certain portions, disapproving other portions, and deferring action on the remaining portions of the attainment plan.
Air Plan Approval; Ohio; Redesignation of the Ohio Portion of the Cincinnati-Hamilton, OH-IN-KY Area to Attainment of the 1997 Annual Standard for Fine Particulate Matter
The Environmental Protection Agency (EPA) is proposing to redesignate the Ohio portion of the Cincinnati-Hamilton, OH-IN-KY, nonattainment area (hereafter, ``the Cincinnati-Hamilton area'') to attainment for the 1997 fine particulate matter (PM2.5) annual national ambient air quality standards (NAAQS or standard). The Ohio portion of the Cincinnati-Hamilton area includes Butler, Clermont, Hamilton, and Warren Counties. Because EPA has determined that the Cincinnati-Hamilton area is attaining the annual PM2.5 standard, EPA is proposing to redesignate the area to attainment and also proposing several additional related actions. EPA is proposing to approve the Reasonably Available Control Measures (RACM)-Reasonably Available Control Technology (RACT) portion of Ohio's Cincinnati- Hamilton area attainment plan SIP revision as providing adequate RACM/ RACT. EPA is proposing to approve an update to the Ohio state implementation plan (SIP), by updating the state's approved plan for maintaining the 1997 annual PM2.5 NAAQS through 2027. EPA previously approved the base year emissions inventory for the Cincinnati-Hamilton area, and is proposing to approve Ohio's updated emission inventory which includes emission inventories for volatile organic compounds (VOCs) and ammonia. Ohio's approved maintenance plan submission includes a budget for the mobile source contribution of PM2.5 and nitrogen oxides (NOX) to the Cincinnati-Hamilton Ohio PM2.5 area for transportation conformity purposes, which EPA is proposing to approve and update. EPA is proposing to take these actions in accordance with the Clean Air Act (CAA) and EPA's implementation rule regarding the 1997 PM2.5 NAAQS.
Promulgation of Air Quality Implementation Plans; State of Texas; Regional Haze and Interstate Visibility Transport Federal Implementation Plan
Pursuant to the Federal Clean Air Act (CAA or Act), the Environmental Protection Agency (EPA) is proposing to promulgate a Federal Implementation Plan (FIP) in Texas to address the remaining outstanding requirements that are not satisfied by the Texas Regional Haze State Implementation Plan (SIP) submission. Specifically, the EPA proposes SO2 limits on 29 Electric Generating Units (EGUs) located at 14 Texas facilities to fulfill requirements for the installation and operation of the Best Available Retrofit Technology (BART) for SO2. To address the requirement for NOX BART for Texas EGU sources, we are proposing a FIP that relies upon two other EPA rulemakings, one already final and one proposed, which together will establish that participation in the Cross-State Air Pollution Rule (CSAPR) continues to qualify as an alternative to NOX BART for EGUs in Texas. We also are proposing to disapprove the portion of the Texas Regional Haze SIP that addresses the BART requirement for EGUs for Particulate Matter (PM) and proposing a FIP with PM BART limits for EGUs at 29 EGUs located at 14 Texas facilities, based on existing practices and control capabilities. In addition, we propose to reconsider and re-propose disapproval of portions of several SIP revisions submitted to satisfy the requirement to address interstate visibility transport for six NAAQS and that the FIP emission limits we are proposing meet the interstate visibility transport requirements for these NAAQS.
Pesticides; Certification of Pesticide Applicators
EPA is updating the existing regulation concerning the certification of applicators of restricted use pesticides (RUPs) in response to public comments received on the proposal and based on extensive stakeholder review of the existing regulation and its implementation since 1974. The final revised regulation will ensure Federal certification program standards adequately protect applicators, the public, and the environment from risks associated with use of RUPs. The final rule will improve the competency of certified applicators of RUPs, increase protection for noncertified applicators using RUPs under the direct supervision of a certified applicator through enhanced pesticide safety training and standards for supervision of noncertified applicators, and establish a minimum age requirement for certified and noncertified applicators using RUPs under the direct supervision of a certified applicator. Recognizing EPA's commitment to work more closely with Tribal governments to strengthen environmental protection in Indian country, the final rule will provide more practical options for establishing certification programs in Indian country.
