Rule 404. (1) Only a person certified by the department as a risk assessor shall conduct
a risk assessment. A risk assessor shall conduct the risk assessment according to this rule.
(2) The risk assessor shall make a visual inspection for risk assessment of a residential
dwelling or child-occupied facility to locate the existence of lead-based paint hazards and
assess the extent and causes of the hazards.
(3) The risk assessor shall collect background information regarding the physical
characteristics of the residential dwelling or child-occupied facility and occupant use
patterns that may cause lead-based paint exposure to 1 or more children age 6 years and
under.
(4) The risk assessor shall test, using documented methodologies, each surface that has
deteriorated paint for the presence of lead if the surface is determined to be in poor
condition and to have a distinct painting history. A risk assessor shall also test, using
documented methodologies, any additional surface for the presence of lead if the surface
is determined to be a potential lead-based paint hazard and to have a distinct painting
history.
(5) In residential dwellings, the risk assessor shall collect the following dust samples in
not less than 6 representative rooms, hallways, stairwells, or room equivalents:
(a) One dust sample from the floor of each selected room, hallway, or stairwell.
(b) One dust sample from a window sill or trough, if available, in each selected room,
hallway or stairwell. Dust samples from windows shall be collected by alternating the sill
and trough in each room to the extent possible.
(c) If there are less than 6 rooms, hallways, stairwells, or room equivalents in the dwelling,
then the risk assessor shall sample all rooms, hallways, and stairwells.
(6) For multifamily dwellings and child-occupied facilities, the risk assessor shall collect
the dust samples required in subrule (5) of this rule in each selected unit. In addition, a risk
assessor shall collect window and floor dust samples in the following locations:
(a) Common areas adjacent to the sampled residential dwelling or child-occupied facility.
(b) Other common areas in the building where the risk assessor determines that 1 or more
children, age 6 and under, could reasonably be expected to come into contact with dust,
regardless of the current occupancy by children in the dwelling.
(7) For child-occupied facilities, the risk assessor shall collect 1 dust sample from the
window sill or trough and 1 dust sample from the floor in each room, hallway, or stairwell
utilized, to the extent defined by a child-occupied facility, by 1or more children, age 6 and
under; and in other common areas in the child-occupied facility where the risk assessor
determines that 1 or more children, age 6 and under, could reasonably be expected to come
into contact with dust to the extent defined by a child-occupied facility.
(8) The risk assessor shall collect soil samples and have the samples analyzed for lead
concentrations in the all of following locations:
(a) Exterior play areas where bare soil is present.
(b) Dripline/foundation areas where bare soil is present
(c) Yard locations in addition to those described in subdivisions (a) and
(b) of this subrule where the area of bare soil exceeds 9 square feet.
(9) The risk assessor shall compare the lead levels from each sample, as determined by
the approved analysis, with applicable hazard levels for lead in paint, dust and soil
established in these rules. The risk assessor shall determine a lead hazard for the area
represented by each sample which exceeds the hazard levels.
