Metro’s Green Construction Policy (GCP) does not apply to City or Special Jurisdiction contractors or construction projects funded by Metro.
Contractors with construction equipment operating in Los Angeles County, however, are subject to regulations implemented and enforced by the California Air Resources Board (ARB), South Coast Air Quality Management District (SCAQMD) and Antelope Valley Air Quality Management District (AVAQMD).
California Air Resources Board
ARB is the department within Cal EPA that promotes and protects public health, welfare, and ecological resources through the reduction of air pollutants while taking the economy of the state into consideration. ARB is responsible for implementing and enforcing programs to reduce particulate matter (PM) and nitrogen oxides (NOx) emissions from diesel-fueled mobile sources.
South Coast Air Quality Management District
SCAQMD is responsible for implementing and enforcing Federal and State air pollution regulations and controlling emissions from stationary sources of air pollution for LA, Orange, Riverside and San Bernardino counties.
Antelope Valley Air Quality Management District
AVAQMD is charged with regulating stationary sources of air pollution in the northern portion of LA County. AVAQMD has adopted similar rules and regulations to that of the SCAQMD.
For more information about ARB, SCAQMD and AVAQMD rules and regulations pertaining to on-road vehicles, off-road construction equipment and portable equipment used on construction projects in LA County, please refer to the resources to the right.
