Designation of Areas for Air Quality Planning Purposes; California; Coachella Valley Ozone Nonattainment Area; Reclassification to Extreme
Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is granting requests by the California Air Resources Board (CARB) to reclassify the Coachella Valley ozone nonattainment area in California from ``Severe-15'' to ``Extreme'' for the 2008 ozone national ambient air quality standards (NAAQS). This action does not reclassify any areas of Indian country within the boundaries of the Coachella Valley 2008 ozone nonattainment area. The new applicable attainment date for the Coachella Valley ozone nonattainment area for the 2008 ozone NAAQS will be the date by which attainment can be achieved as expeditiously as practicable, but no later than July 20, 2032. In connection with the reclassification, the EPA is approving a deadline of no later than 18 months from the effective date of this rule for submittal of revisions to the Coachella Valley portion of the California state implementation plan (SIP) to meet additional requirements for Extreme ozone nonattainment areas. Lastly, the EPA is extending our previous limited approval of the motor vehicle emissions budgets to new budgets to be developed as part of a SIP meeting the Extreme area requirements for the Coachella Valley.
Air Plan Approval; MO; Restriction of Visible Air Contaminant Emissions
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) received on November 29, 2016, and March 7, 2019. The revisions were submitted by Missouri in response to a finding of substantial inadequacy and SIP call published on June 12, 2015, for a provision in the Missouri SIP related to excess emissions during startup, shutdown, and malfunction (SSM) events. In the submissions, Missouri requests to revise a regulation related to restriction of emissions of visible air contaminants. The revisions to the rule include removing a statement from the compliance and performance testing provisions that does not meet Clean Air Act (CAA) requirements, adding exemptions for emission units regulated by stricter federal and state regulations or that do not have the capability of exceeding the emission limits of the rule, adding an alternative test method and making other administrative changes. Approval of these revisions will ensure consistency between state and federally approved rules.
