(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
following an abatement to determine whether or not the abatement has
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."
(86) Wipe sample--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 Determinations by Atomic Spectrometry Techniques," or equivalent
method, with an acceptable wipe material as defined in ASTM E1792,
"Standard Specification for Wipe Sampling Materials for Lead in Surface
Dust."
(87) Working days--Monday through Friday including
holidays that fall on those days.
(88) Worksite--An interior or exterior area at a target
housing or child-occupied facility where lead-based paint abatement
activity is taking place or is scheduled to take place.
(89) X-Ray Fluorescence Analyzer (XRF)--An instrument
used to determine the concentration of lead in a sample; readings
are in milligrams per square centimeter (mg/cm2 ).
(90) Zero-bedroom dwelling--Any residential dwelling
in which the living area is not separated from the sleeping area.
The term includes, but is not limited to, efficiencies, studio apartments,
dormitory housing, military barracks, and rental of individual rooms
in residential dwellings.
