Résumé

The Environmental Protection Agency (EPA) is notifying the public that the Agency has found that the motor vehicle emissions budgets ("budgets") for the year 2020 in the 2016 Air Quality Management Plan (AQMP) for the 2006 fine particulate matter (PM 2.5 ) National Ambient Air Quality Standards (NAAQS) in the Los Angeles-South Coast Air Basin "Serious" nonattainment area ("South Coast 2006 PM 2.5 Serious Area Plan") are adequate for transportation conformity purposes. The California Air Resources Board (CARB) submitted the South Coast 2006 PM 2.5 Serious Area Plan to the EPA on April 27, 2017, as a revision to the California State Implementation Plan (SIP). Upon the effective date of this notice of adequacy, the Southern California Association of Governments (SCAG) and the U.S. Department of Transportation (DOT) must use the adequate budgets in future transportation conformity analyses.
