2008 8-Hour Ozone Standard State Implementation Plan (SIP) Control Strategy Evaluation Effort


In 2012, the Denver Metro/North Front Range Area was designated as Marginal nonattainment for the 2008 National Ambient Air Quality Standard (NAAQS) for ozone. Based on a recent decision by the DC Circuit Court, the attainment deadline for the region is now July 20, 2015. Because the region did not demonstrate attainment by the end of the 2014 ozone season, the region is anticipating a “bump-up” by the U.S. Environmental Protection Agency (EPA) to a Moderate nonattainment area, which has an attainment deadline of July 20, 2018 and requires the development and submittal of an State Implementation Plan (SIP) for this standard.

As part of the SIP development process, a Reasonably Available Control Measures (RACM) analysis must be performed, which will demonstrate that the state has adopted all reasonably available control measures needed to meet the Reasonable Further Progress (RFP) requirements and demonstrate attainment as expeditiously as practicable. As part of this effort, the Regional Air Quality Council (RAQC) Board has formed three subcommittees to evaluate potential strategies for incorporation into the upcoming and/or future SIPs.

All subcommittee meetings are open to the public and interested stakeholders.

Previous Efforts
In 2011, the RAQC conducted a similar effort to evaluate control strategies. A report was presented to the RAQC Board and is the starting point for this current evaluation effort.
