Abstract
EPA is making a technical amendment to the Code of Federal Regulations (CFR) to reflect the Agency's March 1, 2012 final approval of the California State Implementation Plan for attainment of the 1997 8-hour ozone National Ambient Air Quality Standards in the San Joaquin Valley. This technical amendment corrects the CFR to properly codify the California Air Resources Board's commitment to update the air quality modeling in the San Joaquin Valley 8-Hour Ozone SIP by December 31, 2014.
