Abstract
EPA is changing the boundaries of the Searles Valley, California moderate PM-10 nonattainment area (NA) by dividing that area into three new, separate moderate NAs: Coso Junction, Indian Wells Valley, and Trona. EPA is also finding that the Trona NA has attained the 24-hour and annual PM-10 national ambient air quality standards (NAAQS) by the Clean Air Act (CAA) mandated attainment date for moderate nonattainment areas.
