Health & Saf. Code, § 40463

(a) The plan shall be formally reviewed every two years beginning in 1982 by the agencies responsible for preparing plan revisions. In the event of revisions, the compliance schedules and emission limitations shall be amended to reflect advances in technology, control strategies, and administrative practices. The south coast district board may delay submittal of revisions up to two years if necessary to synchronize with the dates of submittal required under the Clean Air Act (42 U.S.C. Sec. 7401 et seq.).

(b) With the active participation of the Southern California Association of Governments, a South Coast Air Basin emission carrying capacity for each state and federal ambient air quality standard shall be established by the south coast district board for each formal review of the plan consistent with subdivision (a) and shall be updated to reflect new data and modeling results. A carrying capacity is the maximum level of emissions which would enable the attainment and maintenance of an ambient air quality standard for a pollutant. Emission carrying capacity for state standards shall not be a part of the state implementation plan requirements of the Clean Air Act for the South Coast Air Basin.

(c) The state board shall review and comment, within 60 days of submittal by the south coast district, on the emission carrying capacity, air quality model selection, and all other data required by this section. The south coast district board and the Southern California Association of Governments Executive Committee shall consider the comments of the state board and shall either accept the state board’s recommendations regarding carrying capacity or shall advise the state board that the recommendations are not accepted.

(d) If the state board receives notification that its recommendations are not accepted, the state board shall convene a conflict resolution committee within 30 days to attempt to resolve the differences. The committee shall be composed 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. The committee shall make a recommendation to the three governing boards.
