(a) Environmental investigation. Within 15 calendar days after being notified by a public health department or other medical health care provider that a child of less than 6 years of age living in a dwelling unit to which this subpart applies has been identified as having an elevated blood lead level, the owner shall complete an environmental investigation of the dwelling unit in which the child lived at the time the blood was last sampled and of common areas servicing the dwelling unit. The requirements of this paragraph apply regardless of whether the child is or is not still living in the unit when the owner receives the notification of the elevated blood lead level. The requirements of this paragraph shall not apply if the owner conducted an environmental investigation of the unit and common areas servicing the unit between the date the child's blood was last sampled and the date when the owner received the notification of the elevated blood lead level. If the owner conducted a risk assessment of the unit and common areas servicing the unit during that period, the owner need not conduct another risk assessment there but shall conduct the elements of an environmental investigation not already conducted during the risk assessment. If a public health department has already conducted an evaluation of the dwelling unit in regard to the child's elevated blood lead level case, the requirements of this paragraph shall not apply.

(b) Verification. After receiving information from a person who is not a medical health care provider that a child of less than 6 years of age living in a dwelling unit covered by this subpart may have an elevated blood lead level, the owner shall immediately verify the information with the public health department or other medical health care provider. If the public health department or provider denies the request, such as because it does not have the capacity to verify that information, the owner shall send documentation of the denial to the HUD rental assistance program manager, who shall make an effort to verify the information. If the public health department or provider verifies that the child has an elevated blood lead level, such verification shall constitute notification, and the owner shall take the action required in paragraphs (a) and (c) of this section.

(c) Lead-based paint hazard reduction. Within 30 calendar days after receiving the report of the environmental investigation conducted pursuant to paragraph (a) of this section or the evaluation from the public health department, the owner shall complete the reduction of identified lead-based paint hazards in accordance with § 35.1325 or § 35.1330. Lead-based paint hazard reduction is considered complete when clearance is achieved in accordance with § 35.1340 and the clearance report states that all lead-based paint hazards identified in the environmental investigation have been treated with interim controls or abatement or the public health department certifies that the lead-based paint hazard reduction is complete. The requirements of this paragraph do not apply if the owner, between the date the child's blood was last sampled and the date the owner received the notification of the elevated blood lead level, already conducted an environmental investigation of the unit and common areas servicing the unit and completed reduction of identified lead-based paint hazards. If the owner conducted a risk assessment of the unit and common areas servicing the unit during that period, the owner is not required to conduct another risk assessment there but shall conduct the elements of an environmental investigation not already conducted during the risk assessment.

(d) If an environmental investigation or lead-based paint hazard evaluation or reduction is undertaken, each owner shall provide notice to occupants in accordance with § 35.125.

(e) Reporting requirement.

(f) Other assisted dwelling units in the property.
