Notice of action: The Department of Environmental Quality (DEQ) is seeking comments and announcing a public comment period on a proposed 2017 base year inventory for precursors to the pollutant ozone, which are carbon monoxide (CO), nitrogen oxides (NO X ), and volatile organic compounds (VOC), in the Northern Virginia Ozone Nonattainment Area. The Commonwealth intends to submit the inventory as a revision to the Virginia State Implementation Plan (SIP) in accordance with the federal Clean Air Act. The SIP is the plan developed by Virginia in order to fulfill its responsibilities under the Act to attain and maintain the National Ambient Air Quality Standards (NAAQS) promulgated by the U.S. Environmental Protection Agency (EPA).

Purpose of notice: DEQ is seeking comments on the overall 2017 inventory for the Northern Virginia portion of the Metropolitan Washington, DC-MD-VA Ozone Nonattainment Area, which is classified as marginal for the 2015 NAAQS, and consists of the counties of Arlington, Fairfax, Loudoun, and Prince William and the cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park.

Public comment period: June 22 to July 22, 2020. This comment period is in addition to the previously conducted public comment period of April 27 to May 27, 2020.
