Jul 12, 2013 — Pre-release — Final Rule — Environmental Protection Agency
40 CFR Part 52 [EPA-R09-OAR-2012-0799; FRL–9833-2]
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
SUMMARY: EPA is taking final action to determine that the Sacramento nonattainment area in California has attained the 2006 24-hour fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS or standard). This 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 PM2.5 NAAQS based on the 2010–2012 monitoring period. Based on the above determination, the requirements for this area to submit an attainment demonstration, together with reasonably available control measures, a reasonable further progress (RFP) plan, and contingency measures for failure to meet RFP and attainment deadlines are suspended for so long as the area continues to attain the 2006 24-hour PM2.5 NAAQS.
NOTE: This is a pre-release version of this Final Rule. It will be formally published on Jul 15, 2013 in the Federal Register. Though it is an official document, it can theoretically be withdrawn before formal publication, and some details may not yet be available.
