Ohio Admin. Code 3701-32-19 - Levels of lead hazardous to human health and clearance examination standards
(A) Lead-based paint is present:
(1) When a paint or other surface coating
contains a lead concentration equal to or exceeding 1.0 mg/cm2 (milligram per square
centimeter), 0.5 percent by weight, or five thousand parts per million (ppm) by
weight; and
(2) On any surface like
a surface tested in the same room that has a lead concentration equal to or
exceeding the level set forth in paragraph (A)(1) of this rule.
(B) Lead-based paint is hazardous
to human health when present:
(1) On any
friction surface where the dust levels on the nearest horizontal surface,
including, but not limited to, window sills or floors, underneath the friction
surface are equal to or exceed:
(a)
Forty
ten
micrograms per square foot or more of lead, if the horizontal surface is an
interior floor or exterior living area
floor;
(b)
Two hundred fifty
One hundred micrograms per square foot or more of
lead, if the horizontal surface is an interior window sill or an exterior
living area window sill; and
(c)
Forty
ten micrograms
per square foot or more of lead, if the horizontal surface is not a window
trough, or an interior window sill; and
(d)
Forty micrograms
per quare foot or more for an exterior living area.
(2) On any chewable lead-based painted
surface that has evidence of teeth marks;
(3) Where there is any damaged or otherwise
deteriorated lead-based paint on an impact surface; or
(4) Where there is deteriorated lead-based
paint in a residential unit, child care facility, or school or on the exterior
of any residential unit, child care facility, or school.
(C) Lead-contaminated dust is hazardous to
human health when present:
(5)
(6) On floors or
interior window sills in an unsampled residential unit or common area in a
multi-family dwelling if a dust lead hazard is present on floors or interior
window sills when random sampling was performed and when the minimum number of
residential units, common areas, or exterior areas, or both, as determined in
appendix C to rule
3701-32-12
of the Administrative Code were sampled. In addition, all the randomly sampled
residential units meet the standards set forth in paragraph (C) of this rule
thereby establishing a ninety-five per cent level of confidence that no more
than five percent or fifty of the residential units, whichever is smaller, have
components that may equal or exceed the hazard standards;
(1) On interior
floors, or exterior living area floors
containing a lead loading of ten
Forty micrograms per square foot or more;
(2) On interior window sills or exterior
living area window sills containing a lead loading of
two
one
hundred fifty micrograms per square foot or
more;
(3) On window troughs
containing a lead loading of
four
one
hundred micrograms per square foot or more lead;
(4) On any horizontal surface if that surface
is not an interior window sill, exterior living area window sill or window
trough containing a lead loading of Forty
ten micrograms per square foot or more;
or
(5)
On exterior
living area floors containing a lead loading of forty micrograms per square
foot or more; or
(D) Lead-contaminated soil is hazardous to
human health when present:
(1) In non-play
areas when the lead concentration from a composite sample, or arithmetic mean
of composite samples, is equal to or exceeds one thousand two hundred
micrograms per gram;
(2) In play
areas when the lead concentration from a composite sample is equal to or
exceeds four hundred micrograms per gram;
(E) Lead-contaminated water pipes that leach
a lead concentration equal to or exceeding:
fifteen micrograms per liter
parts per billion into a flushed water sample collected in accordance with
the procedure specified in 40 C.F.R. 141.86
(2007)
paragraph (B) of rule
3745-81-86
of the Administrative Code are considered hazardous to human
health.
(F) In order to pass a
clearance examination a residential unit, child care facility or school shall:
(1) For single-surface wipes, have a lead
loading less than:
(a)
Forty
ten
micrograms per square foot on interior floors, or
exterior living area floors;
(b)
two
one hundred
fifty micrograms per square foot on
interior window sills, exterior living area window sills, or on any other
interior chewable surface; and
(c)
four
one hundred
micrograms per square foot on window troughs.
; and
(d)
Forty micrograms
per square foot on exterior living area floors.
(2) All horizontal surfaces in the exterior

shall be found to be free of all visible dust and debris.
