The Arizona Department of Environmental Quality has extended its Health Watch for 2.5 micron particulates in effect for Thursday, Dec. 31, to include New Years Day.

This health watch includes restrictions on open burning and woodburning fireplace activity in Maricopa County. This includes individuals and businesses which have burn permits for open burning.

Residents in Maricopa County are urged to eliminate fireplace and wood stove use.

Avoid activities that generate dust, such as driving on dirt roads.

Stabilize loose soils.

Drive as little as possible; car pool, use public transit or telecommute. For information on transportation alternatives, visit Valley Metro: ShareTheRide.com or call 602.253.5000.

Avoid using gas-powered lawn and garden equipment.

PM-2.5 stands for particulate matter measuring 2.5 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.

“Health Watch” means the highest concentration of pollution may approach the federal health standard. Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion during a health watch.
