 The Surprise City Council has approved a PM-10 Dust Control Ordinance, in accordance with state law which requires city, county and state agencies to adopt compliance measures.

PM-10 is a term used to describe very fine airborne particles (particulate matter or PM) that have been known to cause health problems for people in areas in which the PM levels are high. Children, the elderly, people exercising outdoors and those with heart or lung disease or asthma are at an especially high risk to ill effects from PM pollution.

Sources of PM dust pollution include off-road vehicles, driving on unpaved roads, agricultural dust, construction, vacant lands and mining. 

The PM-10 control measures in Surprise are coordinated with other cities in Maricopa County, through the Maricopa Association of Governments (MAG). The objective is a five percent reduction in emissions per year until the PM-10 standard is attained.
