Summary
EPA is proposing to determine that the Pechanga Band of Luiseño Mission Indians of the Pechanga Reservation nonattainment area (“Pechanga nonattainment area” or “Pechanga area”) failed to attain the 2008 national ambient air quality standards for ozone (“ozone NAAQS” or “ozone standards”) by the applicable attainment date. The effect of failing to attain by the attainment date is that the “Moderate” Pechanga nonattainment area will be reclassified by operation of law to “Serious” upon the effective date of the final reclassification action. This proposed action, if finalized, would fulfill the EPA's statutory obligation to determine whether ozone nonattainment areas attained the NAAQS by the attainment date.
