Industry:Pollution control
Health- and welfare-based standards for outdoor air which identify the maximum acceptable average concentrations of air pollutants during a specified period of time. (See also CAAQS and NAAQS and Criteria Air Pollutant. ) For more information, please view our ambient air quality standards website.
Industry:Pollution control
Hybrid electric motor vehicles may operate using both electric and gasoline-powered motors. Emissions from hybrid electric motor vehicles are also substantially lower than conventionally powered motor vehicles. (See also Electric Motor Vehicle. )
Industry:Pollution control
Hydrocarbon- containing compounds such as paint thinner used for the purpose of thinning various types of coatings such as paint.
Industry:Pollution control
Identifiable subsets of the general population that are at greater risk than the general population to the toxic effects of a specific air pollutant (e.g., infants, asthmatics, elderly).
Industry:Pollution control
In the absence of an approved State Implementation Plan (SIP), a plan prepared by the U. S. EPA which provides measures that nonattainment areas must take to meet the requirements of the Federal Clean Air Act.
Industry:Pollution control
Includes tiny particles with an aerodynamic diameter less than or equal to a nominal 2. 5 microns. This fraction of particulate matter penetrates most deeply into the lungs. For more information, please go to our particulate matter website.
Industry:Pollution control
Guidance documents issued by U. S. EPA that define reasonably available control technology (RACT) to be applied to existing facilities that emit excessive quantities of air pollutants; they contain information both on the economic and technological feasibility of available techniques.
Industry:Pollution control
Fuels such as methanol, ethanol, natural gas, and liquid petroleum gas that are cleaner burning and help to meet ARB's mobile and stationary emission standards. These fuels may be used in place of less clean fuels for powering motor vehicles. For more information, please visit our alternative fuels website.
Industry:Pollution control
Gaseous organic compounds, including reactive organic gases and the relatively unreactive organic gases such as methane.
