Summary of Grants Pass PM-10 Maintenance Plan


Grants Pass, Oregon, was designated nonattainment for PM10 upon enactment of the Clean Air Act Amendments in 1990.

Oregon submitted a maintenance plan and redesignation request on November 4, 2002. EPA approved the maintenance plan and redesignation request on October 27, 2003 (68 FR 61111 (PDF)(6 pp, 150 K, About PDF)).


The plan relies on control strategies needed to maintain attainment of the PM10 National Ambient Air Quality Standard ( NAAQS) for particulate matter. The strategy focuses on residential wood combustion, open burning, road dust from motor vehicles, and a major new source review program for industry.
