The American Lung Association, Environmental Defense Fund, Clean Air Council, and Environment and Human Health have filed a legal challenge in the US District Court for the District of Columbia, to require the EPA to update clean air standards for new outdoor wood boilers, furnaces and similar sources that discharge large volumes of woodsmoke. They say the regulations are required by the Clean Air Act and are 17 years overdue. The states of New York, Connecticut, Maryland, Massachusetts, Oregon, Rhode Island, and Vermont, and the Puget Sound Clean Air Agency, filed a similar complaint in the same court.
