Air Plan Approval; California; El Dorado County Air Quality Management District; Reasonably Available Control Technology Demonstration
The Environmental Protection Agency (EPA) is proposing to approve a revision to the El Dorado County Air Quality Management District (EDCAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns the District's demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS) and negative declarations for several source categories. We are proposing action on a local SIP revision under the Clean Air Act (CAA or ``the Act''). We are taking comments on this proposal and plan to follow with a final action.
Air Quality Designation; Illinois; Indiana; Revised Designation of Illinois and Indiana 2012 PM2.5
The Environmental Protection Agency (EPA) is proposing to approve Illinois' May 8, 2018 request to revise the designation for the entire state of Illinois from unclassifiable to unclassifiable/ attainment and Indiana's July 3, 2018 request to revise the designation for the Indiana portions of the Chicago IL-IN and Louisville KY-IN (herein referred to as Chicago and Louisville) areas from unclassifiable to unclassifiable/attainment for the 2012 primary and secondary annual fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve these requests because valid, quality-assured, and certified ambient air monitoring data show that the PM2.5 monitors in the areas are meeting the 2012 primary and secondary annual PM2.5 NAAQS. This includes data from monitors in Illinois where data substitution rules have been applied consistent with applicable regulations.
Air Plan Approval; Illinois; Nonattainment New Source Review Requirements for the 2008 8-Hour Ozone Standard
The Environmental Protection Agency (EPA) is proposing to approve, as a State Implementation Plan (SIP) revision, Illinois' certification that its SIP satisfies the nonattainment new source review (NNSR) requirements of the Clean Air Act (CAA) for the 2008 ozone National Ambient Air Quality Standard (NAAQS or Standard). Final approval of the Illinois NNSR certification SIP will permanently stop the Federal Implementation Plan (FIP) clocks triggered by EPA's February 3 and December 11, 2017 findings that Illinois failed to submit an NNSR plan for the Illinois portion of the Chicago-Naperville, Illinois-Indiana-Wisconsin area (Chicago Nonattainment Area).
Approval and Promulgation of Implementation Plans; New Jersey; Elements for the 2008 8-Hour Ozone National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is approving several State Implementation Plan (SIP) revisions submitted by the State of New Jersey for purposes of implementing Reasonably Available Control Technology (RACT) for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). The EPA is approving New Jersey's SIP revision for the control and prohibition of air pollution by volatile organic compounds (VOCs) and control and prohibition of air pollution by oxides of nitrogen (NOX), as they are intended to satisfy certain control technique guideline (CTG) and NOX RACT categories. The EPA is approving New Jersey's certification that there are no sources within the State for the following CTGs: Manufacture of Vegetable Oils; Manufacture of Pneumatic Rubber Tires; Aerospace Coatings; Shipbuilding and Ship Repair Operations; Metal Furniture Coatings; Large Appliance Coatings; and Auto and Light Duty Truck Original Equipment Manufacturer Assembly Coatings. In addition, the EPA is approving New Jersey's RACT SIP as it applies to non-CTG major sources of VOCs and major sources of NOX. The EPA is also approving the portions of the comprehensive SIP revision submitted by New Jersey that certify that the State has satisfied the requirements for an enhanced motor vehicle Inspection and Maintenance program, certify that the State has satisfied the requirements for an emission statement program, certify that the State has satisfied the requirements for an ozone specific provisions nonattainment new source review program, and show the State has adopted all NOX RACT and VOC RACT, as it pertains to the 2008 8-hour ozone NAAQS. These actions are being taken in accordance with the requirements of the Clean Air Act.
