Not later than 12 months after October 28, 1992, the Secretary, in consultation with the Administrator of the Environmental Protection Agency, the Secretary of Labor, and the Secretary of Health and Human Services (acting through the Director of the Centers for Disease Control), shall issue guidelines for the conduct of federally supported work involving risk assessments, inspections, interim controls, and abatement of lead-based paint hazards. Such guidelines shall be based upon criteria that measure the condition of the housing (and the presence of children under age 6 for the purposes of risk assessments) and shall not be based upon criteria that measure the health of the residents of the housing.
