abatement shall comply with the requirements in
006.01 and the following:
006.04(A)
REQUIRED
PERSONNEL. A licensed supervisor is required for each abatement
project and must be onsite during all work site preparation and during the
postabatement cleanup of work areas. At all other times when abatement
activities are being conducted, the licensed supervisor must be onsite or
available by telephone, pager or answering service, and able to be present at
the work site in no more than two hours.
006.04(B)
PROJECT
NOTIFICATION. Notification of the commencement of lead-based paint
abatement activities in a residential dwelling or child-occupied facility or as
a result of a Federal, State, or local order must be given to the Department
prior to the commencement of abatement activities.
006.04(C)
OCCUPANT PROTECTION
PLAN. A written occupant protection plan must be developed for all
abatement projects, the occupants must be notified of its availability and it
must:
(i) Be unique to each residential
dwelling or child-occupied facility and be developed prior to the abatement. It
must describe the measures and management procedures that will be taken during
the abatement to protect the building occupants from exposure to any lead-based
paint hazards.
(ii) Be prepared by
a licensed supervisor or project designer, and
(iii) Be available to occupants.
006.04(D)
POST
ABATEMENT. The following post-abatement clearance procedures can
only be performed by a licensed inspector or risk assessor:
(i) Following an abatement, a visual
inspection must be performed to determine if deteriorated painted surfaces, 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 178 NAC
23-006.04(D) item
(i). Clearance sampling for lead in dust must be conducted. Clearance sampling
may be conducted by employing single-surface sampling or composite sampling
techniques.
(iii) Dust samples for
clearance purposes must be taken using procedures contained in the Housing and
Urban Development Guidelines for the Evaluation and Control of Lead-Based Paint
Hazards in Housing 2012 edition.
(iv) Dust samples for clearance purposes must
be taken a minimum of one hour after completion of final post-abatement cleanup
activities.
(v) The following
post-abatement clearance activities must be conducted as appropriate based upon
the extent or manner of abatement activities conducted in or to the residential
dwelling or child-occupied facility:
(1) After
conducting an abatement with containment between abated and unabated areas, one
dust sample must be taken from one interior windowsill and from one window
trough, if present, and one dust sample must be taken from the floor of no less
than four rooms, hallways, or stairwells within the containment area. In
addition, one dust sample must 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 must be
sampled.
(2) After conducting an
abatement with no containment, two dust samples must be taken from no less than
four rooms, hallways or stairwells in the residential dwelling or
child-occupied facility. One dust sample must be taken from one window, if
available, and one dust sample must 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 must be sampled.
(3) Following an exterior paint abatement, a
visible inspection must be conducted. All horizontal surfaces in the outdoor
living area closest to the abated surface must be cleaned of visible dust and
debris. In addition, a visual inspection must 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 must be selected according to documented
methodologies.
(vii) A licensed
inspector or risk assessor must compare the residual lead level, as determined
by the laboratory analysis, from each single surface dust sample with clearance
levels in 178 NAC
23-006.02 for lead in dust on
floors, interior windowsills and window troughs or from each composite dust
sample with the applicable clearance levels for lead in dust on floors,
interior windowsills, and window troughs divided by half the number of
subsamples in the composite sample. If the residual lead levels in a single
surface dust sample equals or exceeds the applicable clearance level or if the
residual lead level in a composite dust sample equal or exceeds the applicable
clearance level divided by half the number of subsamples in the composite
sample, the components represented by the failed sample must be recleaned and
retested until clearance levels are met.
(viii) The clearance levels for lead in dust
are 10 µg/ft2 for floors, 100
µg/ft2 for interior windowsills, and 400
µg/ft2 for window troughs.
006.04(E)
MULTI-FAMILY
DWELLINGS. 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
licensed 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.
(iii) The randomly selected
residential dwellings must be sampled and evaluated for clearance according to
the procedures found in 178 NAC
23-006.04(D).
006.04(F)
ABATEMENT
REPORT. An abatement report must be prepared by a licensed
supervisor or project designer, and include the following information:
(i) Start and completion dates of
abatement.
(ii) The name and
address of each licensed firm conducting the abatement and the name of each
supervisor assigned to the abatement project.
(iii) The occupant protection plan prepared
pursuant to 178 NAC
23-006.04(C).
(iv) The name, address, and signature of each
licensed risk assessor or inspector conducting clearance sampling and the date
of clearance testing.
(v) The
results of clearance testing and all soil analyses, if applicable, and the name
of each recognized laboratory that conducted the analyses.
(vi) A detailed written description of the
abatement, including abatement methods used, locations of rooms and components
where abatement occurred, reason for selecting abatement methods for each
component, and any suggested monitoring of encapsulants or
enclosures.
006.04(G)
SAMPLES. Collection and laboratory analysis of
samples: Any paint chip, dust, or soil samples collected pursuant to the work
practice standards contained in 178 NAC
23-006 must be:
(i) Collected by persons licensed as an
inspector or risk assessor; and
(ii) Analyzed by a laboratory recognized by
Environmental Protection Agency pursuant to section 405(b) of Toxics Substance
Control Act as being capable of performing analyses for lead compounds in paint
chip, dust, and soil samples.
006.05
COMPOSITE DUST
SAMPLING. Composite dust sampling may only be conducted in the
situations specified in a lead hazard screen, risk assessment, or abatement. If
such sampling is conducted, the following must apply:
(A) Composite dust samples must consist of at
least two subsamples;
(B) Every
component that is being tested must be included in the sampling; and
(C) Composite dust samples must not consist
of subsamples from more than one type of component. If the residual lead level
in a composite dust sample equals or exceeds the applicable clearance level for
