EPA finalized redesignation of the portion of Kentucky that is within the five-state Louisville, Kentucky – Indiana fine particulate matter (PM2.5) nonattainment area to attainment for the 1997 annual PM2.5 National Ambient Air Quality Standards (NAAQS) and to approve a maintenance plan for the area. See 82 Fed. Reg. 16943 (April 7, 2017).

May 1, 2017

EPA proposed to redesignate the Kentucky portion of the tri-state Cincinnati-Hamilton County, Ohio-Kentucky-Indiana 2008 8-Hour Ozone Nonattainment Area to attainment. EPA also proposed to approve Kentucky’s base year emissions inventory for the Kentucky portion of the area, to approve Kentucky’s plan for maintaining attainment of the 2008 8-Hour Ozone NAAQS in the area, including motor vehicle emission budgets for nitrogen oxides and volatile organic compounds for the years 2020 and 2030 for Kentucky’s portion of the area. EPA finalized the approvals on July 5, 2017. See 82 Fed. Reg. 30976 (July 5, 2017).

EPA proposed to approve Kentucky’s infrastructure State Implementation Plan for the 2012 annual particulate matter (PM2.5) National Ambient Air Quality Standard.

Reg. 21751 (May 10, 2017).

June 29, 2017

EPA proposed to approve revisions to the Louisville-Metro Air Pollution Control District (LMAPCD) stationary source emission monitoring and reporting requirement that it found were consistent with the Clean Air Act. EPA is proposing to approve certain administrative changes as well as changes to reporting data requirements, methods of emissions calculations and stationary source emission statements that are part of Regulation 1.06 of LMAPCD’s rules. See 82 Fed. Reg. 29467 (Thursday, June 29, 2017).

July 17, 2017

EPA proposed to approve changes to the Kentucky State Implementation Plan that would adopt the historical and current National Ambient Air Quality Standards for carbon monoxide, lead, nitrogen dioxide, ozone particulate matter (both PM10 and PM2.5) and sulfur dioxide.

EPA also has proposed to approve several revisions made by LMAPCD:

July 3, 2017

EPA proposed approval of the LMAPCD’s revision to remove Stage II vapor control requirements for new and upgraded gasoline dispensing facilities and allow for the decommissioning of existing Stage II equipment in Jefferson County. EPA approved the demonstration that removal of Stage II vapor recovery systems in the area would and will result in VOC emissions decreases. See 82 Fed. Reg. 30809 (July 3, 2017).

July 28, 2017

EPA issued a direct final rule approving changes to definitions in Regulation 1.02 of the LMAPCD. The changes include revisions to the definition of volatile organic compounds to be consistent with EPA updates. See 82 Fed. Reg 35101 (July 28, 2017).
