For Air Quality Program Officials
As an air quality program official, you know that in some parts of the United States, smoke from wood stoves and fireplaces is the largest source of outdoor air pollution from residential sources. During a typical wood heating season (especially nights and weekends), wood smoke can account for as much as 80% of the particulate matter (PM) emissions in a residential area, depending on usage patterns.
Residents in your area may simply not realize that burning wood inefficiently contributes to air pollution and endangers public health. Many jurisdictions are now seeking the appropriate mix of public education, incentives (rebates), and legal actions that will minimize PM emissions from wood burning stoves and fireplaces.
You can take advantage of the voluntary strategies outlined below to help communities under your responsibility reduce pollution from wood smoke.

The emissions reduced through changing out wood stoves could help your jurisdiction meet or maintain the PM NAAQS - something you may want to consider in your air quality planning. To help with this, EPA has developed a document entitled, "Guidance for Quantifying and Using Emission Reductions from Voluntary Wood Stove Changeout Programs in State Implementation Plans." (PDF, 22 pp, 202 KB) Using this guidance with the assistance of your EPA Regional Office could help your jurisdiction satisfy the requirements of the Clean Air Act.
Public Education on Cleaner Burning Wood Stoves and Fireplaces
A public information campaign to inform local residents about reducing wood smoke can include workshops, community newsletters, media releases, panel discussions and product demonstrations on the local cable access channel, community events at the beginning of the wood heating season, or a special Web site devoted to this topic.
EPA's Web site Cleaner Burning Wood Stoves and Fireplaces is a one-stop resource for consumers. Why not provide a link to it on every town, city, or county Web site within your jurisdiction?
EPA will publish a consumer factsheet in 2005, which you can tailor to local needs, or select language from to use in your pamphlets, handouts, newsletters, or newspaper articles.
Typical themes in a public outreach campaign to reduce wood smoke, which are described more fully on the main pages of this site, can include:
- Replace Stoves Manufactured before 1988. All wood stoves manufactured since 1988 must be EPA certified, which means they use 1/3 less wood than older stoves to produce the same heat. And EPA certified wood stoves emit 50% to 60% less air pollution. EPA certified stoves are easy to identify because they carry a special label and hang tag.
- Purchase only an EPA certified stove. Local residents in the market for a first wood stove should demand to see the EPA label.
- Upgrade a conventional fireplace with an EPA
certified fireplace insert. These function like certified wood stoves.
- Stop burning wood altogether. Where practical and/or available, some local residents can choose cleaner heating options such as natural gas.
- Change the way wood is burned. Residents can reduce the amount of pollution
produced by their wood stove or fireplace by changing how they burn wood. You can encourage
them, for example, to use clean, dry, seasoned hardwood in a wood stove because it generates
the most heat and the least pollution.
Burning small, hot fires produces more heat and less pollution than burning large smoldering fires.
- Properly maintain the wood stove or fireplace. Improperly maintained systems can leak smoke into the home and cause the buildup of creosote, a combustible residue that can fuel a chimney fire. EPA recommends that anyone who burns wood have the chimney professionally cleaned each year to keep it in good working order.
- Weatherize the home. Insufficient insulation and gaps around doors and windows can make a home even colder in the winter. Sealing gaps and holes can cut down on heating needs from wood stoves.
Incentives for Changing to Cleaner Wood Burning Options
Through wood stove changeout campaigns, communities encourage wood stove users to turn in older stoves for recycling and to replace them with either EPA-certified wood stoves or non-wood burning equipment.
Wood stove changeout programs typically provide financial incentives to consumers in the form of rebates, usually 10% to 15% of the purchase price of the new stove.
The campaign costs, including advertising, are covered by a combination of government agencies, gas utilities, and wood stove manufacturers, distributors, and retailers.
If you are considering a local changeout program, learn from others' experiences by visiting the sites below.

Wood Stove Changeout Campaign - EPA is working with partners across the country to encourage homeowners to replace older wood stoves with newer, cleaner burning stoves. Learn more about these changeout campaigns and how they can improve air quality. Also, check for updates on changeout pilot programs in your area.
Community Action - Laws and Ordinances
Certain jurisdictions have established legal requirements to reduce wood smoke. For example, some communities have restrictions on installing wood burning appliances in new construction. The most common and least restrictive action is to limit wood stove and fireplace use at those times when air quality is threatened. The appropriate agency issues an alert, similar to the widespread Ozone Action Day alerts.Model legislative language has been developed by the Bay Area Air Quality Management District in California for communities wishing to take such action.
In 1998 the Bay Area Air Quality Management District, with stakeholder input, developed a model wood smoke ordinance for fireplaces and wood stoves as a guidance document for cities and counties that wish to regulate sources of particulate matter in their communities. The ordinance does not ban wood burning in fireplaces but seeks to take advantage of new, cleaner technologies that have been developed to effectively reduce wood smoke pollution.
This model ordinance template contains language pertaining to reduction of air pollution (PM10 is cited) by regulating the installation or replacement of wood burning appliances. This model ordinance covers all wood burning appliances:
- installed in new residences and commercial buildings
- being added to existing residences and commercial buildings
- that replace wood burning appliances in existing residences and commercial buildings.
Certain Bay area cities have already adopted model ordinances.
