				buildings and structures including, but not limited to, garages, farm
				buildings, and fences, or
(2) a single-family dwelling unit in a structure that contains
				more than one separate residential dwelling unit, which is used or occupied, or
				intended to be used or occupied, in whole or part, as the home or residence of
				one or more persons.
"Risk assessment"
means an investigation to
				determine the existence, nature, severity, and location of lead-based paint
				hazards in a residential dwelling or child-occupied facility and the provision
				of a written report explaining the results of the investigation and options for

				requesting the risk assessment.
"Room"
means a separate part of the inside of
				a building, such as a bedroom, living room, dining room, kitchen, bathroom,

				residential dwelling without the benefit of a risk assessment or other
				evaluation pursuant to 24 CFR Part 35. Standard treatments consist of the
				stabilization of all deteriorated
interior and exterior paint, the provision of smooth and
				cleanable horizontal hard surfaces, the correction of dust-generating
				conditions (i.e., conditions causing rubbing, binding, or crushing of surfaces
				known to or presumed to be coated with lead-based paint), and the treatment of
				bare soil to control known or presumed soil-lead hazards.
"State certification examination"
means a
				discipline-specific examination approved by the department to test the
				knowledge of a person who has completed an approved training course and is
				applying for certification in a particular discipline. The state certification
				examination may not be administered by the provider of an approved
				course.
"Substrate"
means the material underneath the
				paint or finish on a surface. Substrates are classified as brick, concrete,
				drywall, metal, plaster, or wood.
"Substrate correction"
means adjustments that
				must be made to readings obtained from some X-ray fluorescence analyzers to
				correct for systematic biases due to interference from the substrate beneath
				the paint.
"Substrate correction value"

				actual learning, including, but not limited to, time devoted to lecture,
				learning activities, small group activities, demonstrations, evaluations, or
				hands-on experience.
"Training manager"
means the individual
				responsible for administering an approved course and monitoring the performance
				of principal instructors and guest instructors.
"Training program"
means a person or
				organization sponsoring a lead professional training course(s).
"Visual inspection for clearance testing"
means the visual examination of a residential dwelling or a child-occupied
				facility following lead abatement or following interim controls, paint
				stabilization, standard treatments, ongoing lead-based paint maintenance, or
				rehabilitation pursuant to
				24 CFR
				35.1340 to determine whether or not the lead
				abatement, interim controls, paint stabilization, standard treatments, ongoing
				lead-based paint maintenance, or rehabilitation has been successfully
				completed.
"Visual risk assessment"
means a visual
				assessment to determine the presence of deteriorated paint or other potential
				sources of lead-based paint hazards in a residential dwelling or child-occupied
				facility and the provision of a written report explaining the results of the
				assessment to the property owner and to the person requesting the visual risk
				assessment. For the purpose of compliance with this chapter, housing quality
				standards inspections conducted in housing owned by a public housing authority
				and housing that is receiving tenant-based rental assistance from a public
				housing authority are not considered visual risk assessments.
"Weighted arithmetic mean"
means the
				arithmetic mean of sample results weighted by the number of subsamples in each
				sample. Its purpose is to give influence to a sample relative to the surface
				area it represents. A single surface dust sample is comprised of a single dust
				subsample. A composite dust sample may contain from two to four dust subsamples
				of the same area as each other and of each single surface dust sample in the
				composite. The weighted arithmetic mean is obtained by summing, for all dust
				samples, the product of the dust sample's result multiplied by the number of
				dust subsamples in the dust sample, and dividing the sum by the total number of
				dust subsamples contained in all dust samples.
For example, the weighted arithmetic mean of a single surface
				dust sample containing 60 micrograms per square foot
				(µg/ft2), a composite dust sample (three dust
				subsamples) containing 100 µg/ft2, and a
				composite dust sample (four dust subsamples) containing 110
				µg/ft2 is 100
				µg/ft2. This result is based on the equation
				[60+(3×100)+(4×110)] / (1+3+4).
"Wet disposable cleaning cloth"
means a
				commercially available, premoistened white disposable cloth designed to be used
				for cleaning hard surfaces such as uncarpeted floors or countertops.
"Wet mopping system"
means a device with the
				following characteristics: a long handle, a mop head designed to be used with
				disposable absorbent cleaning pads, a reservoir for cleaning solution, and a
				built-in mechanism for distributing or spraying the cleaning solution onto a
				floor, or a method of equivalent efficiency.
"Wet sanding"
means a process of removing
				loose paint in which a surface that is partially coated with paint or other
				surface coating is kept wet or moist during sanding to minimize the dispersal
				of paint chips and airborne dust.
"Wet scraping"
means a process of removing
				loose paint in which a surface that is partially coated with paint or other
				surface coating is kept wet or moist during scraping to minimize the dispersal
				of paint chips and airborne dust.
"Windowsill"
means the portion of the
				horizontal window ledge that protrudes into the interior of the room when the
				window is closed.
"Window trough"
means, for a typical
				double-hung window, the portion of the exterior windowsill between the interior
				windowsill (or stool) and the frame of the storm window. If there is no storm
				window, the window trough is the area that receives both the upper and lower
				window sashes when they are both lowered. The window trough is sometimes
				referred to as the window well.
"Wipe sample"
means a sample collected by
				wiping a representative surface of known area, as determined by ASTM E1728,
				"Standard Practice for Field Collection of Settled Dust Samples Using Wipe
				Sampling Methods for Lead Determination by Atomic Spectrometry Techniques," or

				"Standard Specification for Wipe Sampling Materials for Lead in Surface Dust."
				The minimum area for a floor wipe sample shall be 0.50 square feet or 72 square
				inches. The minimum area for a windowsill wipe sample and for a window trough
				wipe sample shall be 0.25 square feet or 36 square inches.
