On February 12, 2002, chemical manufacturers and EPA agreed to a two-year phase-out of the wood preservative chromated copper arsenate (CCA) for residential uses such as decks, fences and playgrounds. The manufacturers have each decided to seek to amend their respective registrations with EPA for CCA for specific uses. The agreement with EPA does not affect production of treated wood used for industrial and commercial purpose such as utility poles, piling, or highway construction.
The phase-out period begins immediately and ends December 31, 2003. By that date, the production of CCA treated wood for residential purposes must be halted. Existing stocks of CCA treated lumber covered by the agreement may still be sold to the public after that date until stocks are depleted. In announcing the agreement, EPA made it clear that there "is no conclusive evidence that CCA treated wood poses unreasonable risks to the public." EPA also said that there was no reason to replace or remove existing CCA-treated structures.
Given that CCA is used by a substantial number of rural electric systems, there have been several questions asked about disposal issues and whether they were affected by this agreement. The agreement did not address any such issues. Cooperatives must still exercise prudent judgment when deciding how to dispose of any used poles or crossarms. Many systems use both liability waivers and CIS (Consumer Information Sheets) when giving or selling these materials to their members.
