Public Notice: State of California; Finding of Failure To Submit State SIP Required for the 2008 8-Hour Ozone NAAQS for the Sacramento Metro Nonattainment Area

Publish Date: 09/26/2017


EPA is taking final action finding that the state of California has failed to submit State Implementation Plans (SIPs) to satisfy certain requirements of the Clean Air Act (CAA) for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or “standards”). Under the CAA and EPA's implementing regulations, states with nonattainment areas classified as Moderate, Serious, Severe or Extreme were required to submit by July 20, 2016, SIPs demonstrating reasonable further progress (RFP) and attainment of the 2008 8-hour ozone standard as expeditiously as practicable but no later than the applicable dates established in the implementing regulations. States were also required to submit contingency plans to be triggered if attainment or RFP milestones were not met. EPA is by this action making a finding of failure to submit attainment demonstration, attainment demonstration contingency, RFP, and RFP contingency SIPs for the Sacramento Metro nonattainment area. If the EPA has not affirmatively found that the state has submitted the required plans within 18 months, the offset sanction applies in the area. If within 6 additional months the EPA has still not affirmatively determined that the state has submitted the required plan, the highway funding sanction applies in the area. No later than 2 years after the EPA makes the finding, if the state has not submitted, and EPA has not approved, the required SIP, the EPA must promulgate a Federal Implementation Plan.


This action will be effective on October 26, 2017.
