Are there alternatives to pressure-treated wood?
The department recommends that you seek alternatives to CCA-treated wood when selecting building materials for new outdoor structures. Redwood and cedar are naturally rot-resistant, as are wood-plastic composite building materials. Wood that is pressure-treated with alternative preservatives is now available. The wood preservative industry and the Environmental Protection Agency have negotiated a phaseout of CCA-based pressure-treated wood. After December 31, 2003, CCA will not be manufactured, but existing stocks of the treated wood may still be on the market.
