Central Oklahoma Air Quality

The impact of transportation on Central Oklahoma’s quality air is a component of ACOG’s regional planning efforts. Since the establishment of comprehensive federal and state emission regulations by the 1970 Clean Air Act, research has continued to demonstrate the deep relationship between public health and air quality.

While ACOG is not a regulatory body and has no enforcement capabilities, it does work to assure compliance with the Environmental Protection Agency’s National Ambient Air Quality Standards through a variety of programs which serve to educate and affect the public’s capacity to work towards improved air quality in Central Oklahoma.

CART’s Idle Policy

If a CART vehicle will be out of service or offline for 15 minutes or more, the engine should be shut down. If the vehicle is occupied by a driver during an idle time or out-of-service time and the weather is extreme, hot or cold, the vehicle can remain at idle. However, if the weather is tolerable, the driver should shut the engine down.
