(a)
Each district with moderate air pollution shall, to the extent necessary to meet the requirements of the plan developed pursuant to Section 40913, include the following measures in its attainment plan:
(1)
A stationary source control program designed to achieve no net increase in emissions of nonattainment pollutants or their precursors from new or modified stationary sources which emit or have the potential to emit 25 tons per year or more of nonattainment pollutants or
their precursors. The program shall require the use of best available control technology for any new or modified stationary source which has the potential to emit 25 pounds per day or more of any nonattainment pollutant or its precursors.
(2)
The use of reasonably available control technology for all existing stationary sources, except that stationary sources permitted to emit five tons or more per day or 250 tons or more per year shall be equipped with the best available retrofit control technology.
(3)
Reasonably available transportation control measures sufficient to substantially reduce the rate of increase in passenger vehicle trips and miles traveled per trip if the district contains an urbanized area with a population of 50,000 or more.
(4)
Provisions to develop areawide source and indirect source
control programs.
(5)
Provisions to develop and maintain an emissions inventory system to enable analysis and progress reporting and a commitment to develop other analytical techniques to carry out its responsibilities pursuant to subdivision (b) of Section 40924.
(6)
Provisions for public education programs to promote actions to reduce emissions from transportation and areawide sources.
(b)
Any district with moderate air pollution that is not below the pollutant concentrations for a moderate classification pursuant to Sections 40921 and 40921.5 by December 31, 1997, shall comply with Section 40919 if the state board demonstrates that the additional requirements of Section 40919 will substantially expedite the district’s attainment of the state ambient air quality standards. Any actions taken by the state board
pursuant to this subdivision are subject to Section 41503.4.
