(a) 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 designated party 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. When the environmental investigation is complete, the designated party shall immediately provide the report of the environmental investigation to the owner of the dwelling unit. If the child identified as having an elevated blood lead level is no longer living in the unit when the designated party receives notification from the public health department or other medical health care provider, but another household receiving tenant-based rental assistance is living in the unit or is planning to live there, the requirements of this section apply just as they do if the child still lives in the unit. 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, or the designated party 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 designated party received the notification of the elevated blood lead level, the requirements of this paragraph shall not apply. If the designated party or the owner conducted a risk assessment of the unit and common areas servicing the unit during that period, the designated party need not conduct another risk assessment there but shall conduct the elements of an environmental investigation not already conducted during the risk assessment.

(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 designated party 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 designated party shall send documentation of the denial to the HUD rental assistance program manager, who shall make an effort to verify the information. If that department or provider verifies that the child has an elevated blood lead level, such verification shall constitute notification, and the designated party 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 from the designated party 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 designated party or the owner, between the date the child's blood was last sampled and the date the designated party received the notification of the elevated blood lead level, already conducted an environmental investigation of the unit and common areas servicing the unit and the owner completed reduction of identified lead-based paint hazards. If the owner does not complete the lead-based paint hazard reduction required by this section, the dwelling unit is in violation of the standards of 24 CFR 982.401.

(d) Notice of lead-based paint hazard evaluation and reduction. The owner shall notify building residents of any lead-based paint hazard evaluation or reduction activities in accordance with § 35.125.

(e) Reporting requirement. (1) The owner shall report the name and address of a child identified as having an elevated blood lead level to the public health department within 5 business days of being so notified by any other medical health care professional.

(2) The owner shall also report each confirmed case of a child with an elevated blood lead level to the HUD field office and the HUD Office of Lead Hazard Control and Healthy Homes within 5 business days of being so notified.

(3) The owner shall provide to the HUD field office documentation that it has conducted the activities of paragraphs (a) through (d) of this section, within 10 business days of the deadline for each activity.

(f) Other assisted dwelling units in the property. (1) If the environmental investigation conducted pursuant to paragraph (a) of this section identifies lead-based paint hazards, the designated party or the owner shall, for other assisted dwelling units covered by this part in which a child under age 6 resides or is expected to reside on the date lead-based paint hazard reduction under paragraph (c) of this section is complete, and the common areas servicing those units, conduct a risk assessment in accordance with § 35.1320(b) within 30 calendar days after receipt of the environmental investigation report if there are 20 or fewer such units, or 60 calendar days if there are more such units.

(2) If the risk assessment conducted under paragraph (f)(1) of this section identifies lead-based paint hazards, the owner shall complete the reduction of the lead-based paint hazards in accordance with § 35.1325 or § 35.1330 within 30 calendar days, or within 90 calendar days if more than 20 units have lead-based paint hazards such that the control work would disturb painted surfaces that total more than the de minimis threshold of § 35.1350(d). 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 risk assessment have been treated with interim controls or abatement.

(3) The requirements of this paragraph (f) of this section do not apply if:

(i) The designated party or 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, both conducted a risk assessment of the other assisted dwelling units covered by paragraph (f)(1) of this section and the common areas servicing those units, and the owner conducted interim controls of identified lead-based paint hazards in accordance with § 35.1225(c); or

(ii) The owner has documentation of compliance with evaluation, notification, lead disclosure, ongoing lead-based paint maintenance, and lead-based paint management requirements under this part throughout the 12 months preceding the date the owner received the environmental investigation report pursuant to paragraph (a) of this section; and,

(iii) In either case, the owner provided the HUD field office, within 10 business days after receiving the notification of the elevated blood lead level, documentation that it has conducted the activities described in this paragraph (f)(3).

(g) Data collection and record keeping responsibilities. At least quarterly, the designated party shall attempt to obtain from the public health department(s) with area(s) of jurisdiction similar to that of the designated party the names and/or addresses of children of less than 6 years of age with an identified elevated blood lead level. At least quarterly, the designated party shall also report an updated list of the addresses of units receiving assistance under a tenant-based rental assistance program to the same public health department(s), except that the report(s) to the public health department(s) is not required if the health department states that it does not wish to receive such report. If it obtains names and addresses of elevated blood lead level children from the public health department(s), the designated party shall match information on cases of elevated blood lead levels with the names and addresses of families receiving tenant-based rental assistance, unless the public health department performs such a matching procedure.

If a match occurs, the designated party shall carry out the requirements of this section.
