Biological Testing. For every unit to be assisted with Program funds, the sponsor shall make a good faith effort to ensure that each child younger than 6 years old receives a blood lead test within the 3-month period before the beginning of lead abatement treatment. Testing shall be performed by the local health department or other party approved by MDE. The project sponsor shall assist in obtaining the cooperation of tenants for the blood testing. Environmental Testing. The testing in §§C—E of this regulation is required for each unit receiving abatement treatment under the Program. Initial Testing. Every room or area in a dwelling unit planned for abatement shall: Receive a risk assessment as defined in Regulation .03B of this chapter; and Undergo testing as defined in Regulation .03B of this chapter. Risk assessment, initial wipe tests, and other testing shall be performed by certified contractors and trained workers selected by the sponsor and acceptable to the Program. Clearance Testing. Before a dwelling unit may be re-occupied, the unit shall undergo a wipe test showing that lead dust levels are below HUD's maximum allowable standard for floors (currently 100 micrograms per square foot), window sills (currently 500 micrograms per square foot), and window wells (currently 800 micrograms per square foot). All lead dust samples shall be collected directly by MDE personnel or others approved by the Program.
