Sec. 9.
The following post-abatement final visual clearance
procedures shall be performed only by a licensed inspector or risk
assessor:
(1) Following an abatement
and prior to removal of warning signs or other demarcation, a visual inspection
shall be completed by an Indiana licensed inspector or risk assessor to
determine if deteriorated, painted surfaces or visible amounts of dust, debris,
or residue are still present.
(2)
If deteriorated painted surfaces or visible amounts of dust debris or residue
are present, they must be wet wiped or HEPA vacuumed until such conditions are
eliminated prior to the continuation of the clearance procedures.
(3) Following the visual inspection and any
post-abatement cleanup required in this rule, clearance sampling for
lead-contaminated dust shall be conducted by employing single-surface sampling
or composite sampling techniques.
(4) Dust samples on surfaces for clearance
purposes shall be taken using documented methodologies that incorporate
adequate quality control procedures.
(5) Dust samples for clearance purposes shall
be taken within a minimum of one (1) hour after completion of final
post-abatement clean-up activities.
(6) 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 target housing or child-occupied
facility:
(A) After conducting an abatement
with containment between abated and unabated areas:
(i) one (1) dust sample shall be taken from
one (1) interior window sill and from one (1) window trough, if
present;
(ii) one (1) dust sample
shall be taken from the floors of each of no less than four (4) rooms,
hallways, or stairwells within the containment area; and
(iii) one (1) dust sample shall be taken from
the floor outside the containment area.
If there are fewer than four (4) 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:
(i) two (2) dust samples shall
be taken from each of no fewer than four (4) rooms, hallways, or stairwells in
the target housing or child-occupied facility;
(ii) one (1) dust sample shall be taken from
one (1) interior window sill and one (1) window trough, if present;
and
(iii)
one (1) dust sample shall be taken from the floor of each room, hallway, or
stairwell selected. If there are fewer than four (4) rooms, hallways, or
stairwells within the residential dwelling or child-occupied facility, then all
rooms, hallways, or stairwells shall be sampled.
(C) Following an exterior paint abatement, a
visible inspection shall be conducted as follows:
(i) All horizontal surfaces in the outdoor
living area closest to the abated surface shall be found to be clean of visible
dust and debris.
(ii) 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.
(iii) If paint chips are present, the chips
shall be removed from the site and properly disposed of according to all
applicable federal, state, and local requirements.
(D) The rooms, hallways, or stairwells
selected for sampling shall be selected according to documented
methodologies.
(E) The licensed
inspector or risk assessor shall compare the residual lead level, as determined
by the laboratory analysis, from each single surface dust sample with
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:
(i) in a
single surface dust sample equals or exceeds the applicable clearance levels;
or
(ii) in a composite dust sample
equals or exceeds the applicable clearance level divided by half the number of
subsamples in the composite sample;
then the sample is a failed sample. All the components
represented by the failed sample shall be recleaned and retested until
clearance levels are met.
(F) The clearance levels for lead in dust are
a mass-per-area concentration of lead equal to or exceeding the hazard
threshold of a specific building component as set forth by the United States
Environmental Protection Agency, 40 CFR Part 745 *, effective March 8, 2021.
