Pentachlorophenol on the Way Out

U.S. EPA has announced that it will cancel the registration of pentachlorophenol, a common wood preservative. U.S. EPA has determined that the risks associated with pentachlorophenol are greater than the benefits, especially considering that alternatives are available. Wood treatment facilities can continue to purchase pentachlorophenol for the next two years while exploring and switching to alternatives, and will have a further three years to use existing stocks.
