(a)  Following submittal by the south coast district, the state board shall review the plan to determine its adequacy to meet federally mandated primary ambient air quality standards and all other requirements of the federal Clean Air Act (42 U.S.C. Sec. 7401 et seq.) and its adequacy to meet the requirements of the California Clean Air Act of 1988 (Chapter 1568, Statutes of 1988) and to attain state ambient air quality standards through application of the best available control technology, indirect source controls, transportation control measures, and the use of cleaner burning alternative fuels. If the state board determines that portions of the plan meet the requirements of the state and federal acts and are adequate to attain state ambient air quality standards, it shall adopt those portions and submit to the Environmental Protection Agency the portions of the plan required by the federal act within 120 days after receipt of the plan from the south coast district.

(b)  If the state board determines that the plan does not meet all the requirements of the state and federal acts, or does not include a deadline for the attainment of the state ambient air quality standards by application of the best available control technology, indirect source controls, transportation control measures, and the use of cleaner burning alternative fuels, the state board shall, prior to amending the plan, convene a committee comprised of two members each of the state board, the Executive Committee of the Southern California Association of Governments, and the south coast district board appointed by the entity they represent to attempt to resolve the differences. If it is necessary to amend the plan, the state board shall do so at a public hearing held pursuant to Section 41652 and shall submit to the Environmental Protection Agency the portions of the plan required by the federal act within 120 days after receipt of the plan from the south coast district. In submitting the plan to the Environmental Protection Agency, the state board shall indicate what changes have been made to the plan.

(c)  Within 30 days after the receipt of the plan from the south coast district, the state board shall determine if, with respect to any part of the plan concerning the control of a source of emissions that is within the state board’s responsibility under law, it has sufficient information to determine whether the plan, or any part of the plan, meets the applicable requirements of the state and federal acts and is adequate to attain state ambient air quality standards. The state board shall thereupon notify the south coast district, in writing, of the additional information needed to make the determination, and the south coast district shall promptly furnish the information.
