Lead Hazard Screen means a limited risk assessment activity that involves paint testing and dust sampling and analysis as described in 40 CFR 745.227(c) and soil sampling and analysis as described in 40 CFR 745.227(d).
A lead hazard screen may be conducted first in housing for which a risk assessment is required, to determine whether hazards exist and a complete risk assessment should be conducted: risk assessments are required in units affected by subpart C, D, G , H, I, J , L
24 CFR 35.1320(b)(3) Lead hazard screens shall be performed in accordance with the methods and standards established either by a State or Indian tribe under a program authorized by EPA, or by EPA at 40 CFR 745.227(c), and paragraph (b)(2) of this section. If the lead hazard screen indicates the need for a follow-up risk assessment (e.g., if dust-lead measurements exceed the levels established for lead hazard screens in this section), a risk assessment shall be conducted in accordance with paragraphs (b)(1) and (b)(2) of this section. Dust, soil, and paint samples collected for the lead hazard screen may be used in the risk assessment. If the lead hazard screen does not indicate the need for a follow-up risk assessment, no further risk assessment is required.
