| (C) Soil-lead hazard. A soil-lead hazard is bare soil

children's possessions, observations of play patterns, or information
provided by parents, residents, care givers, or property owners.
(65) Principal instructor--The individual who has the
primary responsibility for organizing and teaching a particular course.
(66) Recognized laboratory--An environmental laboratory
recognized by EPA, pursuant to the Toxic Substances Control Act (TSCA) §405(b),
as being capable of performing an analysis for lead content in materials,
including paint, soil, and dust.
(67) Reduction--Any measures designed to reduce or
eliminate human exposure to lead-based paint hazards through methods,
including, but not limited to, interim controls and abatement.
(68) Residential building--A building containing one
or more residential dwellings.
(69) Residential dwelling--A dwelling that is:
(A) a detached single family dwelling unit, including
attached structures such as porches and stoops; or
(B) 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
in part, as the home or residence of one or more persons.
(70) Risk assessment--An assessment consists of:
(A) an on-site investigation conducted by a certified
risk assessor to determine the existence, nature, severity, and location
of lead-based paint hazards; and
(B) a written report by the person or the firm conducting
the risk assessment, explaining the results of the investigation and
options for reducing lead-based paint hazards.
(71) Room--A separate part of the inside of a building,
such as a bedroom, living room, dining room, kitchen, bathroom, laundry
room, or utility room. To be considered a separate room, the room
must be separated from adjoining rooms by built-in walls or archways
that extend at least six inches from an intersecting wall. Half walls
or bookcases count as room separators if built-in. Movable or collapsible
partitions or partitions consisting solely of shelves or cabinets
are not considered built-in walls. A screened in porch that is used
as a living area is a room.
(72) Soil Sample--A sample collected in a representative
location using ASTM E1727, "Standard Practice for Field Collection
of Soil Samples for Lead Determination by Atomic Spectrometry Techniques,"
or equivalent method.
(73) Start-date--The date that the lead abatement begins.
(74) Stop-date--The date that all dust-wipe clearance
levels are achieved and reported to the lead firm conducting the abatement
for interior abatement, or for exterior abatement, the date that visual
clearance levels are all achieved.
(75) Target housing--Any housing constructed prior
to 1978, except housing for the elderly or persons with disabilities
(unless any child who is six years of age or younger resides or is
expected to reside in such housing) or any zero-bedroom dwelling.
As defined in this section, target housing includes the terms residential
dwelling, multi-family dwelling, and unit.
(76) Testing--The collection of paint, soil, or dust-wipe
samples for determining the presence of lead in paint or lead-based
paint hazards by an EPA recognized laboratory or the use of an XRF.
(77) Training curriculum--An established set of course
topics for instruction in an accredited training program for a particular
discipline designed to provide specialized knowledge and skills.
(78) Training hour--At least 50 minutes of actual teaching,
including, but not limited to, time devoted to lecture, learning activities,
small group activities, demonstrations, evaluations, and hands-on
experience.
(79) Training manager--The individual responsible for
administering a training program and monitoring the performance of
principal instructors and guest instructors.
(80) TSCA--Toxic Substances Control Act (15 United
States Code §2681 et seq) Title IV.
(81) Unit--A room or connected group of rooms used
or intended to be used by a single tenant or owner.
(82) Visual inspection for clearance testing--The visual
examination of a residential dwelling or a child-occupied facility

been successfully completed, as indicated by the absence of visible
residue, dust, and debris.
(83) Visual inspection for risk assessment--The visual
examination of a residential dwelling or a child-occupied facility
to determine the existence of deteriorated lead-based paint or other
potential sources of lead-based paint hazards.
(84) Weighted arithmetic mean--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 sample is comprised of a single
subsample. A composite sample may contain from two to four subsamples
of the same area as each other and of each single surface sample in
the composite. The weighted arithmetic mean is obtained by summing,
for all samples, the product of the sample's result multiplied by
the number of subsamples in the sample, and dividing the sum by the
total number of subsamples contained in all samples. For example,
the weighted arithmetic mean of a single surface sample containing
60 µg/ft2 , a composite sample (three
subsamples) containing 100 µg/ft2 ,
and a composite sample (four subsamples) containing 110 µg/ft2 is 100 µg/ft2 .
This result is based on the equation [60 + (3*100) + (4*110)]/(1+3+4).
(85) Window trough--For a typical double-hung window,
the portion of the exterior window sill between the interior window
sill (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 trough
is sometimes referred to as the window "well."
