(b) The congestion mitigation and air quality improvement program funds shall be apportioned by the department to the metropolitan planning organizations designated pursuant to Section 134 of Title 23 of the United States Code and, in areas where none has been designated, to the transportation planning agency established by Section 29532 or 29532.1 of the Government Code. All funds apportioned to the state pursuant to Section 104(b)(4) of Title 23 of the United States Code shall be apportioned to metropolitan planning organizations and transportation planning agencies responsible for air quality conformity determinations in federally designated air quality nonattainment and maintenance areas within the state as follows:

1. (1) The department shall apportion these funds in the ratio that the weighted nonattainment and maintenance population in each federally designated area within the state bears to the total of all weighted nonattainment and maintenance area populations in the state.

2. (2) Subject to paragraph (3), the weighted nonattainment and maintenance area population shall be calculated by multiplying the population of each area in the state that is a nonattainment area or maintenance area as described in Section 149(b) of Title 23 of the United States Code for ozone or carbon monoxide by the following factors:

   1. (A) A factor of 1.0, if, at the time of apportionment, the area is a maintenance area.
   2. (B) A factor of 1.0, if, at the time of the apportionment, the area is classified as a marginal ozone nonattainment area under Subpart 2 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7511 et seq.).
   3. (C) A factor of 1.1, if, at the time of the apportionment, the area is classified as a moderate ozone nonattainment area under Subpart 2 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7511 et seq.).
   4. (D) A factor of 1.2, if, at the time of the apportionment, the area is classified as a serious ozone nonattainment area under Subpart 2 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7511 et seq.).
   5. (E) A factor of 1.3, if, at the time of the apportionment, the area is classified as a severe ozone nonattainment area under Subpart 2 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7511 et seq.).
   6. (F) A factor of 1.4, if, at the time of the apportionment, the area is classified as an extreme ozone nonattainment area under Subpart 2 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7511 et seq.).
   7. (G) A factor of 1.0, if, at the time of the apportionment, the area is not a nonattainment or maintenance area for ozone, but is classified under Subpart 3 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7512 et seq.) as a nonattainment area for carbon monoxide.
   8. (H) A factor of 1.0, if, at the time of the apportionment, an area is designated as a nonattainment area for ozone under Subpart 1 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7512 et seq.).
3. (3) If, in addition to being designated as a nonattainment or maintenance area for ozone as described in paragraph (2), any county within the area is also classified under Subpart 3 of Part D of Title I of the Clean Air Act (42 U.S.C. Sec. 7512 et seq.) as a nonattainment or maintenance area described in paragraph (2) for carbon monoxide, the weighted nonattainment or maintenance area population of the county, as determined under subparagraphs (A) to (F), inclusive, or subparagraph (H) of paragraph (2), shall be further multiplied by a factor of 1.2.
4. (4) Funds allocated under this subdivision shall remain available for three federal fiscal years, including the federal fiscal year apportioned.

(c)

1. (1) Notwithstanding subdivision (b), where county transportation commissions have been created by the County Transportation Commissions Act (Division 12 (commencing with Section 130000) of the Public Utilities Code), all congestion mitigation and air quality improvement program funds shall be further apportioned by the metropolitan planning organization to the county transportation commission on the basis of relative population within the federally designated air quality nonattainment and maintenance areas after first apportioning to the nonattainment and maintenance areas in the manner and in accordance with the formula set forth in subdivision (b).
2. (2) In the Monterey Bay region, all congestion mitigation and air quality improvement program funds shall be further apportioned, on the basis of relative population, by the metropolitan planning organization to the regional transportation planning agencies designated under subdivision (b) of Section 29532 of the Government Code.

(d)

1. (1) The department shall notify each metropolitan planning organization, transportation planning agency, and county transportation commission receiving an apportionment under this section, as soon as possible each year, of the amount of obligational authority estimated to be available for expenditure from the federal apportionment. The metropolitan planning organizations, transportation planning agencies, and county transportation commissions, in cooperation with the department, congestion management agencies, cities and counties, and affected transit operators, shall select and program projects in conformance with federal law. Each metropolitan planning organization and transportation planning agency shall, not later than October 1 of each even-numbered year, submit its Federal Transportation Improvement Program prepared pursuant to Section 134 of Title 23 of the United States Code to the department for incorporation into the Federal Statewide Transportation Improvement Program. Federal Transportation Improvement Programs shall, at a minimum, include the years covered by the Federal Statewide Transportation Improvement Program.
2. (2) Notwithstanding paragraph (1), a metropolitan planning organization or transportation planning agency shall not be required to submit a Federal Transportation Improvement Program to the department for 2020.
