This paper describes the current EPA system for regulating pesticides and wood preservatives. In particular it focuses on the voluntary phase-out of CCA for residential uses after December 30, 2003, which was agreed between the CCA manufacturers and EPA. Even though the EPA reached an agreement with industry to phase out CCA for residential uses, EPA is continuing the most rigorous risk assessment ever done on a wood preservative pesticide. One risk assessment is considering children’s exposure at residential sites and the other focuses on the uses that are not subject to the phase-out agreement, e.g. fence posts and wood in permanent foundations.
