Plan to Improve Air Quality in the Washington, DC-MD-VA Region, State Implementation Plan (SIP) (“Severe Area SIP”) for Washington, DC-MD-VA Ozone Nonattainment Area|
This document, 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 Severe Area Attainment Plan shows the progress being made on improving air quality in the Washington nonattainment area and the efforts underway to assure that the region takes all necessary steps to reach the federal health standard for ground-level ozone by 2005.
The Metropolitan Washington Air Quality Committee (MWAQC) approved the revised ”Plan to Improve Air Quality in the Washington, DC-MD-VA Region,” on February 19, 2004. Visit the SIP page to download the appendices to the SIP.
