130A-131.9C. Abatement and remediation.

(a) Upon determination that a child less than six years of age or a pregnant woman has a confirmed lead poisoning of 10 micrograms per deciliter or greater and that child or pregnant woman resides in a residential housing unit containing lead poisoning hazards, the Department shall require remediation of the lead poisoning hazards. The Department shall also require remediation of the lead poisoning hazards identified at the supplemental addresses of a child less than six years of age or a pregnant woman with a confirmed lead poisoning of 10 micrograms per deciliter or greater.

(b) When remediation of lead poisoning hazards is required under subsection (a) of this section, the owner or managing agent shall submit a written remediation plan to the Department within 14 days of receipt of the lead poisoning hazard notification and shall obtain written approval of the plan before initiating remediation activities. The remediation plan shall comply with subsections (g), (h), and (i) of this section.

(c) If the remediation plan submitted fails to meet the requirements of this section, the Department shall issue an order requiring submission of a modified plan. The order shall indicate the modifications that shall be made to the remediation plan and the date that the plan as modified shall be submitted to the Department.

(d) If the owner or managing agent does not submit a remediation plan within 14 days, the Department shall issue an order requiring submission of a remediation plan within five days of receipt of the order.

(e) The owner or managing agent shall notify the Department and the occupants of the dates of remediation activities at least three days before commencement of the activities.

(f) Remediation of the lead poisoning hazards shall be completed within 60 days of the Department's approval of the remediation plan. If the remediation activities are not completed within 60 days, the Department shall issue an order requiring completion of the activities. An owner or managing agent may apply to the Department for an extension of the deadline. The Department may issue an order extending the deadline for 30 days upon proper written application by the owner or managing agent.

(g) All of the following methods of remediation of lead-based paint hazards are prohibited:

(1) Stripping paint on-site with methylene chloride-based solutions.

(2) Torch or flame burning.

(3) Heating paint with a heat gun above 1,100 degrees Fahrenheit.

(4) Covering with new paint or wallpaper unless all readily accessible lead-based paint has been removed.

(5) Uncontrolled abrasive blasting, machine sanding, or grinding, except when used with High Efficiency Particulate Air (HEPA) exhaust control that removes particles of 0.3 microns or larger from the air at ninety-nine and seven-tenths percent (99.7%) or greater efficiency.

(6) Uncontrolled waterblasting.

(7) Dry scraping, unless used in conjunction with heat guns, or around electrical outlets, or when treating no more than two square feet on interior surfaces, or no more than 20 square feet on exterior surfaces.

(h) All lead-containing waste and residue shall be removed and disposed of in accordance with applicable federal, State, and local laws and rules. Other substances containing lead that are intended for use by children less than six years of age or pregnant women and vinyl miniblinds that constitute a lead poisoning hazard shall be removed and disposed of in accordance with applicable federal, State, and local laws and rules.

(i) All remediation plans shall require that the lead poisoning hazards be reduced to the following levels:

(1) Fewer than 40 micrograms per square foot for lead dust on floors.

(2) Fewer than 250 micrograms per square foot for lead dust on interior windowsills, bathtubs, kitchen sinks, and lavatories.

(3) Fewer than 400 micrograms per square foot for lead dust on window troughs.

(4) Fewer than 400 parts per million for lead in bare soil in play areas, gardens, pet sleeping areas, and areas within three feet of the residential housing unit or child-occupied facility. Lead in bare soil in other locations of the yard shall be reduced to less than 1,200 parts per million.

(5) Fewer than 15 parts per billion for lead in drinking water.

(j) The Department shall verify by visual inspection that the approved remediation plan has been completed. The Department may also verify plan completion by residual lead dust monitoring and soil or drinking water lead level measurement.

(j1) Compliance with the maintenance standard satisfies the remediation requirements for confirmed lead poisoning cases identified on or after 1 October 1990 as long as all lead poisoning hazards identified on interior and exterior surfaces are addressed by remediation. Except for owner-occupied residential housing units, continued compliance shall be verified by means of an annual monitoring inspection conducted by the Department. For owner-occupied residential housing units, continued compliance shall be verified (i) by means of an annual monitoring inspection, (ii) by documentation that no child less than six years of age and no pregnant woman has resided in or regularly visited the residential housing unit within the past year, or (iii) by documentation that no child less than six years of age and no pregnant woman residing in or regularly visiting the unit has an elevated blood lead level.

(k) Removal of children or pregnant women from the residential housing unit or removal of children from the child-occupied facility shall not constitute remediation if the property continues to be used for a residential housing unit or child-occupied facility. The remediation requirements imposed in subsection (a) of this section apply so long as the property continues to be used as a residential housing unit or child-occupied facility.
