The inclusion of Form 2.13 Wood Stove Addendum is crucial in the sale agreement if the property has a wood stove. The Clean Air Act mandates the Environmental Protection Agency to establish performance standards for all stationary sources of air pollution, including residential wood heaters. In 1991, Oregon passed laws to reduce and prevent air pollution caused by “solid fuel burning devices.” However, this does not apply to cookstoves, antique stoves, pellet stoves, masonry heaters, fireplaces, and central wood-fired furnaces.
