Abstract
EPA is finding that the Imperial Valley serious PM-10 nonattainment area did not attain the 24-hour particulate matter (PM- 10) National Ambient Air Quality Standard (NAAQS) by the deadline mandated in the Clean Air Act (CAA), December 31, 2001. In response to this finding, the State of California must submit a revision to the California State Implementation Plan (SIP) that provides for attainment of the PM-10 standard in the Imperial Valley area and at least five percent annual reductions in PM-10 or PM-10 precursor emissions until attainment as required by CAA section 189(d). The State must submit the SIP revision by December 11, 2008.
