Valley Air Board makes daily forecasts for use of fireplaces.

The 10th season of the Valley Air Pollution Control District's Check Before You Burn wintertime pollution-reduction program began Nov. 1.
Because of Valley residents’ ongoing efforts and understanding of the importance of changing long-ingrained habits in ways that reduce emissions, Check Before You Burn has resulted in historically clean wintertime air quality in the Valley over the past several years. The wood-burning curtailment program is critical in minimizing levels of harmful particulate matter (PM) in the eight-county air basin.
“Thanks to the public’s support and cooperation, this rule is the single most-effective, lowest-cost regulation on record in the Valley,” said Seyed Sadredin, the District’s executive director and air pollution control officer. “It is absolutely imperative to improved air quality.”
Each day, the Air District issues a wood-burning forecast by county for one of two levels: “Wood-burning prohibited” or “Please Burn Cleanly.”
When wood burning is prohibited, all residential wood burning -- including fireplaces, wood-burning inserts and heaters, pellet stoves and outdoor devices such as fire pits and chimineas -- is prohibited.
When the forecast is “Please Burn Cleanly,” the District encourages residents to use manufactured fire logs or dry, seasoned wood. And of course, gas fireplace use is always allowed.
Residential wood burning is the single largest source of harmful PM during winter and can pump 17 tons of PM into Valley skies daily. Fine-particulate matter (PM2.5) exacerbates respiratory illness, such as asthma; causes lung infections and bronchitis; and has been correlated with increased risk of heart attacks and stroke.
There are two exceptions to wood-burning prohibitions:
•If the residence does not have access to natural-gas service, even if propane is used; or
•If burning solid fuel is the sole source of heat for the residence.
Prohibition violations are subject to fines.
Daily wood-burning forecasts are available each day at 4:30 p.m. at, by calling 1-800 SMOG INFO (766-4463), or by subscribing to the Air District’s daily air quality forecast at
