3900 Air Resources Board
3500 - MOBILE SOURCE
The Mobile Source Program works to improve air quality by reducing emissions from on- and off-road mobile sources as follows:
- Enforce laws and develop, implement, and enforce regulations limiting criteria pollutants, greenhouse gases, and toxic air contaminants 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 emission standards are met.
3505 - STATIONARY SOURCE
The Stationary Source Program works with air pollution control districts and business and scientific communities to reduce emissions from stationary sources to comply with state and federal laws as follows:
- Develop, implement, and enforce 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, implement, and enforce measures to control toxic air contaminant emissions from stationary sources.
3510 - CLIMATE CHANGE
The Climate Change Program works to reduce greenhouse gas emissions to 1990 levels by 2020, and further reduce emissions to 80 percent of 1990 levels by 2050, as follows:
- Develop, implement, and enforce measures for reducing greenhouse gas emissions, including emissions from mobile and stationary sources, as required by the California Global Warming Solutions Act of 2006 (AB 32, Chapter 488, Statutes of 2006).
- Enforce laws and develop, implement, and enforce regulations to achieve the required greenhouse gas emission reductions and other requirements of AB 32.
- Develop, implement, and oversee programs to achieve greenhouse gas emission reductions, including grant, loan, and other incentive programs.
3515 - SUBVENTION
The Air Resources Board provides subventions to local air pollution control districts to encourage and support effective district programs. The state's 35 local air pollution control districts have primary responsibility for controlling stationary sources of air pollution in California.
