Reduce emissions of wood smoke.

Residential wood burning devices, including as outdoor wood boilers and stoves, are the largest
residential source of particle pollution. While emissions harmful air pollutants from wood burning
devices have limited national or regional impact on air quality and public health, it could have
significant impacts on owners of such devices and immediate neighbors. The U.S. Census (2011)
reports that nearly two percent of all U.S. households use wood as a primary heat source. In 2006, one
study estimated that approximately 14 to 17 million such devices were then in use in the United States.

• Besides particle pollution, wood burning also produces carbon monoxide, nitrogen oxides,
sulfur dioxide, and even toxic air pollution. Studies have found that wood smoke leads to
coughing and shortness of breath, decreases in lung function, and aggravated asthma and may
even cause cancer.

• Although most states use the EPA standards for particle pollution to determine which wood
burning devices can be sold, the EPA’s standards have not been updated since 1988. Since
then, improved technologies that limit harmful emissions from wood burning devices have
been developed and are in use. The EPA is currently reviewing the standards and needs to
update them to reflect this new technology and require that all wood burning devices to burn
cleaner to reduce impacts on public health.

• Emissions from outdoor wood boilers used to heat residences also need to be cleaned up. As
their use increases, the EPA is considering its options to regulate outdoor wood boiler
emissions. However, the agency has yet to issue a proposal, originally scheduled for summer
2011 with final rules set for summer 2012. The EPA needs to adopt a standard to limit
emissions from these devices to avoid the patchwork of state regulations currently in place.
• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
