The U.S. Environmental Protection Agency (EPA) has issued new work practice standards for remodelers of older homes in an effort to reduce lead paint exposure, particularly among children. Set to take effect in April 2010, the new standards will extend to builders, painters, plumbers, and electricians working in all rental housing built before 1978, as well as in older non-rental homes inhabited by children under age six or pregnant women. The standards will apply to any renovation, repair, or painting contract involving the disturbance of more than 6 square feet of lead paint in an interior room or 20 square feet of lead paint on an exterior wall.
