DISCUSSION/BACKGROUND
In 2017, the EPA found the Sacramento region attained the 2006 federal 24-hr PM2.5 National Ambient Air Quality Standards (NAAQS). However, EPA has not yet designated the region attainment for PM2.5. Therefore, western El Dorado County (approximately Pollock Pines westward to the County line) is still designated as nonattainment of the 2006 24-hr PM2.5 NAAQS. Western El Dorado County (EDC) is also designated as nonattainment for the 2008 and 2015 8-hr Ozone NAAQS. As such, EPA requires AQMD to implement measures to control emissions of VOC and NOx as ozone precursors and PM2.5 and the PM2.5 precursors NOx, SOx, VOC and ammonia from major stationary sources. A “major source” is defined as any stationary source of air pollutants which emits, or has the potential to emit, more than 25 tons per year (tpy) of Volatile Organic Compounds/Reactive Organic Compounds (VOC/ROC) or Oxides of Nitrogen (NOx) in areas classified as “severe”, or 70 tpy or more of PM10 or PM2.5.
AQMD and the Sacramento region have committed to reducing pollution by submitting a federally enforceable SIP. A New Source Review Rule (NSR) is required as part of the SIP. NSR Rule 523 is currently SIP-approved, however, Rule 523 does not include or apply to PM2.5.
In March 2016, AQMD adopted Rule 523-1 Federal Nonattainment New Source Review to address PM2.5, as well as ozone precursors. Adoption of Rule 523-1 satisfied the federal 2006 PM2.5 and...
