Inspection requirements
The Secretary shall require the inspection of all intact and nonintact interior and exterior painted surfaces of housing subject to this section for lead-based paint using an approved x-ray fluorescence analyzer, atomic absorption spectroscopy, or comparable approved sampling or testing technique. A certified inspector or laboratory shall certify in writing the precise results of the inspection. If the results equal or exceed a level of 1.0 milligrams per centimeter squared or 0.5 percent by weight, the results shall be provided to any potential purchaser or tenant of the housing. The Secretary shall periodically review and reduce the level below 1.0 milligram per centimeter squared or 0.5 percent by weight to the extent that reliable technology makes feasible the detection of a lower level and medical evidence supports the imposition of a lower level. The requirements of this subsection shall apply as provided in subsection (d).
