Abstract

On February 28, 2025, the State of North Carolina, through the North Carolina Department of Environmental Quality, Division of Air Quality (NCDAQ), submitted a request for the Environmental Protection Agency (EPA) to approve a State Implementation Plan (SIP) revision containing the State’s plan for maintaining the 2008 ozone National Ambient Air Quality Standard (NAAQS) through 2035 for the North Carolina portion of the bi-state Charlotte-Rock Hill, North Carolina-South Carolina 2008 8-hour ozone nonattainment area (the entire area is hereinafter referred to as the “bi-State Charlotte Area” and the North Carolina portion is hereinafter referred to as the “Charlotte Area”). EPA is proposing to approve and incorporate North Carolina’s second 10-year maintenance plan in order to maintain attainment of the 2008 8-hour ozone NAAQS in the bi-State Charlotte Area, including the 2018 and 2035 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NOx) and volatile organic compounds (VOC) for the Charlotte Area, into the SIP. EPA is also notifying the public of the status of EPA's adequacy determination for the sub-area MVEBs for the Charlotte Area.
