If a chute is used to remove waste from the work area, it must be covered.(ii) At the conclusion of each work day and at the conclusion of the abatement, waste that has been collected from the abatement must be stored under containment, in an enclosure, or behind a barrier that prevents release of dust and debris out of the work area and prevents access to dust and debris.(iii) When the firm transports waste from the abatement, the firm must contain the waste to prevent release of dust and debris.(i) If conducted, soil abatement shall be conducted in one of the following ways: (i) If the soil is removed: (A) The soil shall be replaced by soil with a lead concentration as close to local background as practicable, but no greater than 400 ppm; and(B) The soil that is removed shall not be used as top soil at another residential property or child-occupied facility; or(ii) If soil is not removed, the soil shall be permanently covered, as defined in R307-840-2.(j) The following post-abatement clearance procedures shall be performed only by a certified inspector or risk assessor: (i) Following an abatement, a visual inspection shall be performed to determine if deteriorated painted surfaces and/or visible amounts of dust, debris, or residue are still present. If deteriorated painted surfaces or visible amounts of dust, debris, or residue are present, these conditions must be eliminated prior to the continuation of the clearance procedures;(ii) Following the visual inspection and any post-abatement cleanup required by paragraph (5)(h)(i) of this section, clearance sampling for lead in dust shall be conducted. Clearance sampling may be conducted by employing single-surface sampling or composite sampling techniques;(iii) Dust samples for clearance purposes shall be taken using documented methodologies that incorporate adequate quality control procedures;(iv) Dust samples for clearance purposes shall be taken a minimum of 1 hour after completion of final post-abatement cleanup activities;(v) The following post-abatement clearance activities shall be conducted as appropriate based upon the extent or manner of abatement activities conducted in or to the residential dwelling or child-occupied facility:(A) After conducting an abatement with containment between abated and unabated areas, one dust sample shall be taken from one interior window sill and from one window trough (if present) and one dust sample shall be taken from the floors of each of no less than four rooms, hallways, or stairwells within the containment area. In addition, one dust sample shall be taken from the floor outside the containment area. If there are less than four rooms, hallways, or stairwells within the containment area, then all rooms, hallways, or stairwells shall be sampled;(B) After conducting an abatement with no containment, two dust samples shall be taken from each of no less than four rooms, hallways, or stairwells in the residential dwelling or child-occupied facility. One dust sample shall be taken from one interior window sill and window trough (if present) and one dust sample shall be taken from the floor of each room, hallway, or stairwell selected. If there are less than four rooms, hallways, or stairwells within the residential dwelling or child-occupied facility, then all rooms, hallways, or stairwells shall be sampled; and(C) Following an exterior paint abatement, a visible inspection shall be conducted. All horizontal surfaces in the outdoor living area closest to the abated surface shall be found to be cleaned of visible dust and debris. In addition, a visual inspection shall be conducted to determine the presence of paint chips on the dripline or next to the foundation below any exterior surface abated. If paint chips are present, they must be removed from the site and properly disposed of, according to all applicable federal, state, and local requirements;(vi) The rooms, hallways, or stairwells selected for sampling shall be selected according to documented methodologies;(vii) The certified inspector or risk assessor shall compare the residual lead level (as determined by the laboratory analysis) from each single surface dust sample with clearance levels in paragraph (5)(h)(viii) of this section for lead in dust on floors, interior window sills, and window troughs or from each composite dust sample with the applicable clearance levels for lead in dust on floors, interior window sills, and window troughs divided by half the number of subsamples in the composite sample. If the residual lead level in a single surface dust sample equals or exceeds the applicable clearance level or if the residual lead level in a composite dust sample equals or exceeds the applicable clearance level divided by half the number of subsamples in the composite sample, the components represented by the failed sample shall be recleaned and retested; and(viii) The clearance levels for lead in dust are 10 ug/ft2 for floors, 100 ug/ft2 for interior window sills, and 400 ug/ft2 for window troughs.(ix) Occupants of the home shall not be allowed into the abatement work area until clearance dust sample results are received by the inspector or risk assessor and are found to be acceptable according to dust-lead clearance level standards.(k) In a multi-family dwelling with similarly constructed and maintained residential dwellings, random sampling for the purposes of clearance may be conducted provided: (i) The certified individuals who abate or clean the residential dwellings do not know which residential dwelling will be selected for the random sample;(ii) A sufficient number of residential dwellings are selected for dust sampling to provide a 95% level of confidence that no more than 5% or 50 of the residential dwellings (whichever is smaller) in the randomly sampled population exceed the appropriate clearance levels; and(iii) The randomly selected residential dwellings shall be sampled and evaluated for clearance according to the procedures found in paragraph (5)(h) of this section.(l) An abatement report shall be prepared by a certified supervisor or project designer no later than 30 business days after receiving the results of final clearance testing and all soil analyses (if applicable).
