Proposed Stage Implementation Plan Revision:

Spokane PM10 Limited Maintenance Plan and Redesignation Request



Local air pollution control agencies periodically submit air quality plan updates and regulations to the Department of Ecology (ecology) for inclusion in Washington's state implementation plan (SIP). The SIP is a statewide plan for meeting federal health-based standards for certain air pollutants.

The Spokane area is designated nonattainment for particulate matter air pollution equal to or less than ten microns in size (PM10). This means that, in the past, the area did not meet federal health-based standards for PM10. As the area has been meeting the standards since 1994, it can now be redesignated to attainment by the federal Environmental Protection Agency (EPA).

The Spokane County Air Pollution Control Agency and ecology have prepared a plan, called a limited maintenance plan, for PM10. This plan demonstrates that the Spokane area meets Federal Clean Air Act requirements for PM10. It also summarizes the progress of the area in attaining the PM10 standard, demonstrates that the Spokane area qualifies for EPA's limited maintenance plan option, and includes a maintenance plan to assure continued attainment for ten years after the redesignation. The plan includes a formal request to EPA to redesignate the Spokane, Washington, PM10 nonattainment area to attainment for the health-based twenty-four-hour average PM10 national ambient air quality standard.

Copies of the plan are available for review at the Spokane County Air Pollution Control Authority, 1101 West College, Suite 403, Spokane, WA 99201; at the Spokane Public Library, 906 West Main, Spokane, WA 99201; at the Spokane Regional Transportation Council, 211 West First Avenue, Suite 310, Spokane WA 99201; and at the Department of Ecology, Eastern Regional Office, 4601 North Monroe Street, Spokane, WA 99205-1295.

Hearing schedule: On Tuesday, October 26, 2004, at 4:30 p.m., at the Washington Department of Ecology, Eastern Regional Office, 2nd Floor Conference Room, 4601 North Monroe Street, Spokane, WA 99205-1295.
