## Abstract

EPA is making technical amendments to the Code of Federal Regulations (CFR) to reflect the Agency's March 1, 2012 final approvals of the California State Implementation Plans for attainment of the 1997 8-hour ozone National Ambient Air Quality Standards in the San Joaquin Valley and the South Coast Air Basin. These technical amendments correct the CFR to properly codify the California Air Resources Board's commitments to propose certain defined measures.
