VIOLATIONS OF FEDERAL CLEAN AIR STANDARDS BY DUST-IN-THE-AIR

Maricopa County: Living Here is Hazardous To Your Health

"High Pollution Advisory" or "HPA" means the highest concentration of pollution may exceed the federal health standard. Active children, adults and people with lung disease such as asthma should reduce prolonged or heavy outdoor exertion. Maricopa County employers enlisted in the Travel Reduction Program are asked to activate their HPA plans on high pollution advisory days.

The Arizona Department of Environmental Quality has issued a PM-10 High Pollution Advisory for Tuesday, February 15.     Children, the elderly, and people with heart and/ or lung disease should reduce prolonged or heavy outdoor exertion.

Take Action

Avoid activities that generate dust, such as driving on dirt roads. Stabilize loose soils. Eliminate fireplace and wood stove use. Avoid using leaf blowers. Use a rake or broom to keep debris out of the road and away from storm drains, ditches, and streams. Use electric lawn and garden equipment. Check if you are eligible to receive up to $200 to replace gasoline powered lawn equipment by visiting CleanAirMakeMore.com/lawn. Drive as little as possible: carpool, use public transit, or telecommute. For information on transportation alternatives, visit Valley Metro: www.ShareTheRide.com

> Regulated Businesses

Due to the expected high winds, businesses conducting dust-generating operations need to be vigilant of their dust control measures. Workers may need to cease operating, after stabilizing disturbed areas, if water application and other dust control measures prove ineffective.

Maricopa County Air Quality Department inspectors will be conducting surveillance of fugitive dust sources in the county on days that are deemed high risk for particulate matter. Sources observed violating the particulate matter standards will be issued Notices of Violation.

Transportation Coordinators

Due to unhealthy levels of particulate matter, Maricopa County Air Quality Department requests all Transportation Coordinators to email employees and activate your HPA plans. The department encourages the use of alternative modes of transportation, especially when pollution levels are expected to be on the rise.

Remind employees that they are encouraged to make more clean air. By taking small, simple steps every day, we can all make a difference. Additional tips on how to reduce air pollution can be found at www.CleanAirMakeMore.com.

PM-10 stands for particulate matter measuring 10 microns or less. State and county agencies measure PM-10 and PM-2.5 which are extremely small solid particles and liquid droplets found circulating in the air. PM, or particulate matter, comes from either combustion (cars, industry, woodburning) or dust stirred up into the air.

High levels of PM are typically created when the air is especially stagnant.
