Zusammenfassung
EPA is approving the State of California's request to redesignate the Coso Junction planning area (CJPA) to attainment for the particulate matter of ten microns or less (PM-10) national ambient air quality standard (NAAQS). EPA is also approving the PM-10 emissions inventory and the maintenance plan for the CJPA, including control measures for Owens Lake, the primary cause of PM-10 nonattainment in the CJPA. Finally, EPA is finding the contribution of motor vehicles to the area's PM-10 problem insignificant; consequently, the State will not have to complete a regional emissions analysis for PM-10 in any future transportation conformity determination for the CJPA.
