OZONE PLANS
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia request that the United States Environmental Protection Agency (USEPA) approve revisions to the original 2008 ozone national ambient air quality standard (NAAQS) maintenance plan (dated December 20, 2017) for the Washington DC-MD-VA 2008 Ozone NAAQS Maintenance Area. These revisions include changes to onroad motor vehicle emissions budgets (MVEBs) for volatile organic compounds (VOC) and nitrogen oxides (NOX) based on the EPA approved MOVES3.0.4 model.
Submitted by District of Columbia & Commonwealth of Virginia
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia submitted to the United States Environmental Protection Agency (USEPA) a comprehensive base year emissions inventory for 2017 to meet the requirements for the Washington DC-MD-VA 2015 ozone National Ambient Air Quality Standard (NAAQS) nonattainment area (Note: The State of Maryland submitted a different version of this inventory document dated May 26, 2020 to EPA.) Emissions inventories included for the District of Columbia and the Commonwealth of Virginia in this version are different from the version submitted by the State of Maryland due to corrections made to inventories of the two jurisdictions to primarily accommodate recent changes in EPA’s NEI 2017 data.
Submitted by the State of Maryland
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia submitted to the United States Environmental Protection Agency (USEPA) a comprehensive base year emissions inventory for 2017 to meet the requirements for the Washington DC-MD-VA 2015 ozone National Ambient Air Quality Standard (NAAQS) nonattainment area. (Note: The District of Columbia and the Commonwealth of Virginia submitted a different version of this inventory document dated October 30, 2020 to EPA.) Emissions inventories included for the District of Columbia and Virginia in this version are different from the version submitted by the District of Columbia and the Commonwealth of Virginia due to corrections made to inventories after May 26, 2020 of the two jurisdictions to primarily accommodate recent changes in EPA’s NEI 2017 data.
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia request that the United States Environmental Protection Agency (USEPA) redesignate the Washington DC-MD-VA 2008 ozone National Ambient Air Quality Standard (NAAQS) marginal nonattainment area to attainment for this standard pursuant to the provisions under § 107 of the federal Clean Air Act (CAA).
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia are submitting to the United States Environmental Protection Agency (USEPA) a comprehensive base year emissions inventory for 2011 to meet the requirements for the Washington DC-MD-VA 2008 ozone National Ambient Air Quality Standard (NAAQS) nonattainment area.
The EPA-required plan, called a State Implementation Plan (SIP), presents air quality data showing the region will meet the federal standard for ozone -- a harmful gas formed when the sun heats polluted air -- by the fall of 2009. The plan includes a list of measures to reduce pollution from ozone-forming gases.
The Severe Area Attainment Plan for the Metropolitan Washington Nonattainment Area, focuses on improving air quality in the Washington region to meet the national air quality standard for ozone (one-hour ozone standard). The Plan consists of two Rate of Progress demonstrations, for the period 1999-2002 and for 2002-2005; and an attainment demonstration for 2005. The Metropolitan Washington Air Quality Committee approved the revised “Plan to Improve Air Quality in the Washington, DC-MD-VA Region,” on February 19, 2004.
FINE PARTICLES (PM2.5) PLANS
The District of Columbia, the State of Maryland, and the Commonwealth of Virginia request that the United States Environmental Protection Agency (USEPA) redesignate the Washington DC-MD-VA 1997 fine particulate (PM2.5) nonattainment area to attainment for this standard pursuant to the provisions under § 107 of the federal Clean Air Act (CAA).
The Metropolitan Washington Air Quality Committee (MWAQC) approved an air quality plan to reduce fine particle pollution in the region. The plan goes beyond Clean Air Act requirements in an effort to gain further reductions in fine particle pollution. The plan was adopted by MWAQC on March 7, 2008.
