## Abstract

EPA is taking direct final action to approve the Limited Maintenance Plan for the Spokane nonattainment area (NAA) in Washington and grant the request by the State to redesignate the area from nonattainment to attainment for PM10. On November 30, 2004, the State of Washington submitted a Limited Maintenance Plan (LMP) for the Spokane nonattainment area (NAA) for approval and concurrently requested that EPA redesignate the Spokane NAA to attainment for the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10). In 1997, EPA approved Washington's moderate area plan for the Spokane NAA for all PM10 sources except windblown dust. In this direct final action, EPA is also approving the remaining elements of the Spokane NAA moderate area plan for windblown dust sources.
