Environmental Protection Agency January 19, 2024 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Jefferson County portion of the Kentucky State Implementation Plan (SIP) submitted by the Commonwealth of Kentucky through the Kentucky Energy and Environment Cabinet (Cabinet) on June 13, 2022. The changes were submitted by the Cabinet on behalf of the Louisville Metro Air Pollution Control District (District, also referred to herein as Jefferson County). EPA is proposing to approve changes to the District's rules on the construction or modification of major stationary sources that are located within nonattainment areas or that have emissions impacting nonattainment areas. EPA also is proposing to approve the certification submitted by Kentucky on behalf of the District that the new version of the Nonattainment New Source Review (NNSR) permitting regulations proposed for incorporation into the Jefferson County portion of the Kentucky SIP meets the NNSR nonattainment planning requirements for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS). The certification covers the Jefferson County portion of the Louisville, Kentucky-Indiana multi- state nonattainment area for the 2015 8-hour ozone NAAQS. This action is proposed pursuant to the Clean Air Act (CAA or Act) and its implementing regulations.

The Environmental Protection Agency (EPA) is approving Indiana's September 21, 2023, state implementation plan (SIP) submission which revises the 2008 ozone maintenance plan for the Indiana portion (Lake and Porter Counties) of the Chicago Naperville, IL-IN-WI area (Chicago Naperville area). This SIP submission updates onroad vehicle emissions inventories for oxides of nitrogen (NOX) and volatile organic compounds (VOC) for the years 2019, 2030 and 2035. In addition to updated emissions inventories, this SIP submission updates the Motor Vehicle Emissions Budgets (budgets) for NOX and VOC for the years 2030 and 2035. EPA is approving the allocation of a portion of the safety margins for VOC and NOX in the ozone maintenance plan to the 2030 and 2035 budgets. Total year 2030 and 2035 emissions of NOX and VOC for the area will remain below the attainment level required by the transportation conformity regulations.

The Environmental Protection Agency (EPA) is proposing to approve a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a Source-specific SIP (SSSIP) revision for Finch Paper LLC, located at 1 Glen Street, Glens Falls, New York (Facility). The control options in this SSSIP revision address nitrogen oxide (NOX) Reasonably Available Control Technology (RACT) for the Facility sources identified as four power boilers, a wood waste boiler, and four recovery boilers. The intended effect of this SSSIP revision is to approve NOX RACT for the Facility sources required for implementation of the 2008 and 2015 ozone NAAQS. This proposed action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).
