EPA Mandates New CCA-Treated Wood Regulations
Vancouver, BC— The Environmental Protection Agency (EPA) will no longer allow chromated copper arsenate (CCA) to be used to treat wood intended for most residential settings. This transition limits virtually all residential uses of wood treated with CCA, including wood no longer acceptable for use in play structures, decks, picnic tables, landscaping timbers, residential fencing, patios, walkways and boardwalks. Additionally, CCA-treated inventories will no longer be produced as of December 31, 2003, and all remaining inventories exhausted by mid-2004 for the majority of consumer usage.
CCA-treated wood contains arsenic, a known human carcinogen linked to skin, bladder, lung, liver and kidney cancers, which can be particularly unsafe due to naturally occurring leaching over time.
“This action will result in a reduction of virtually all residential uses of CCA-treated wood within less than two years,” said former EPA Administrator Christie Whitman. “This is a responsible action by the industry that will ensure that future exposures to arsenic are minimized in residential settings.”
Here are some common-sense tips for minimizing unnecessary exposure to CCA:
An excellent, non-treated wood alternative is western red cedar. Renewable and biodegradable, cedar does not require chemical treatment due to its unique naturally occurring preservatives resistant to rot and insects.
“Natural qualities of western red cedar make it an excellent choice for a wide range of building projects both inside the home and outside the home,” said Peter Lang, general manager of the Western Red Cedar Lumber Association. “It’s naturally durable without the need for chemical treatment, dimensionally stable, resilient, and lightweight - unlike some plastic or imitation wood products.”
Lang said when properly finished, western red cedar will last for decades, even in harsh environments.
