Traduction automatique locale · Langue originale de la source
Résumé
EPA is proposing to determine that the Chico nonattainment area in California has attained the 2006 24-hour fine particle (PM 2.5 ) National Ambient Air Quality Standard (NAAQS). This proposed determination is based upon complete, quality-assured, and certified ambient air monitoring data showing that this area has monitored attainment of the 2006 24-hour PM 2.5 NAAQS based on the 2009-2011 monitoring period. EPA is further proposing that, if EPA finalizes this determination of attainment, the requirements for this area to submit an attainment demonstration, together with reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures for failure to meet RFP and attainment deadlines shall be suspended for so long as the area continues to attain the 2006 24-hour PM 2.5 NAAQS.
