Diesel Idling


P-21  Vehicle Idling Restriction Ordinance


Reducing emissions from diesel engines is one of the most important air quality challenges facing the country. Even with EPA’s more stringent heavy-duty highway and non-road engine standards set to take effect over the next decade, millions of diesel engines already in use will continue to emit large amounts of nitrogen oxides, particulate matter and air toxics, which contribute to serious public health problems. The Maricopa County Air Quality Department is dedicated to achieving emission reductions from diesel sources.

 

1)  P-21 Maricopa County Vehicle Idling Restriction Ordinance On June 26, 2002, Maricopa County adopted an ordinance restricting idling of heavy-duty diesel vehicles. The purpose of this ordinance is to protect public health and the environment by reducing emissions of toxics and criteria pollutants while also conserving fuel.  These vehicles are required to limit idling to no longer than five minutes under most circumstances.
