Program Descriptions

15 - MOBILE SOURCE

The Mobile Source Program works to improve air quality by reducing emissions from internal combustion engines as follows:
  • Develop, implement and enforce laws and regulations limiting emissions from new and in-use vehicles and other mobile sources and assess the effectiveness of established procedures.
  • Develop testing and evaluation procedures for vehicles, engines, emission control components, fuel additives and test equipment to ensure that emission standards are met.
  • Conduct information and training seminars for vehicle dealers, mechanics, inspectors and members of the public on vehicle emissions and resulting air pollution.

25 - STATIONARY SOURCE

The Stationary Source Program works with air pollution control districts and the business and scientific communities to reduce emissions from stationary sources to comply with state and federal laws as follows:

  • Develop measures for reducing emissions from stationary and other sources as required by the California Clean Air Act and work with local air pollution control districts to achieve and maintain state and federal ambient air quality standards.
  • Identify substances that are toxic air contaminants and develop measures to control their emissions.
  • Assist industries wishing to locate or expand in California and provide comments to lead agencies and districts on applications for permits to construct or modify facilities that are major sources of air pollution.

32 - CLIMATE CHANGE

The Climate Change Program works to reduce greenhouse gas emissions to 1990 levels by 2020, and then an 80 percent reduction below 1990 levels by 2050, as follows:
  • Develop measures for reducing greenhouse gas emissions, including from mobile and stationary sources, as required by the California Global Warming Solutions Act of 2006 (AB 32, Chapter 488, Statutes of 2006).
  • Develop, implement, and enforce laws and regulations to achieve the required greenhouse gas emission reductions and other requirements of AB 32.

35 - SUBVENTION

The Air Resources Board provides subventions to local air pollution control districts in order to encourage and provide support for effective district programs. The state's 35 local air pollution control districts have the primary responsibility for controlling stationary sources of air pollution in California.
