Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part III - Air › Chapter 28 - Lead-Based Paint Activities-Recognition, Accreditation, Licensure, and Standards for Conducting Lead-Based Paint Activities › Section III-2811 - Work Practice Standards for Conducting LeadBased Paint Activities for Target Housing and Child-Occupied Facilities

Current through Register Vol. 50, No. 6, June 20, 2024
A. Applicability and Terms
1. All lead-based paint activities shall be
				performed in accordance with the work practice standards contained in this
				Section, except when treating paint-lead hazards of less than 2 square feet of
				deteriorated lead-based paint per room or equivalent, 20 square feet of
				deteriorated paint on the exterior of a building, or 10 percent of the total
				surface area of deteriorated paint on an interior or exterior type of component
				with a small surface area.
2. When
				performing an inspection, lead-hazard screen, risk assessment, or abatement, an
				accredited individual must perform that activity in compliance with the
				appropriate requirements contained in this Section.
3. Hazards related to paint, dust, and soil
				shall be determined as follows.
a. Lead-based
				paint is present on any surface that is tested and found to contain lead equal
				to or in excess of 1.0 milligrams per square centimeter or equal to or in
				excess of 0.5 percent by weight, and on any surface like a surface tested in
				the same room equivalent that has a similar painting history and that is found
				to be lead-based paint.
b. A
				paint-lead hazard shall be considered present:
i. on any friction surface that is subject to
				abrasion and where the lead dust levels on the nearest horizontal surface
				underneath the friction surface (e.g., the window sill or floor) are equal to
				or greater than the dust hazard levels defined in this Chapter;
ii. on any chewable lead-based paint surface
				on which there is evidence of teeth marks;
iii. where there is any damaged or otherwise
				deteriorated lead-based paint on an impact surface that is caused by impact
				from a related building component (such as a door knob that knocks into a wall
				or a door that knocks against its door frame); and
iv. if there is any other deteriorated
				lead-based paint in any residential building or child-occupied facility or on
				the exterior of any residential building or child-occupied facility.
c. A dust-lead hazard shall be
				considered present:
i. in a residential
				dwelling or child-occupied facility on floors and interior window sills where
				the weighted arithmetic mean lead loading for all single surface or composite
				samples of floors and interior window sills are 10 micrograms per square foot
				or greater for floors and 100 micrograms per square foot or greater for
				interior window sills, respectively;
ii. on floors or interior window sills in an
				unsampled residential dwelling in a multi-family dwelling, if a dust-lead
				hazard is present on floors or interior window sills, respectively, in at least
				one sampled residential unit on the property; and
iii. on floors or interior window sills in an
				unsampled common area in a multi-family dwelling, if a dust-lead hazard is
				present on floors or interior window sills, respectively, in at least one
				sampled common area in the same common area group on the property.
d. A soil-lead hazard shall be
				considered present:
i. in a play area when
				the soil-lead concentration from a composite play area sample of bare soil is
				equal to or greater than 400 parts per million; or
ii. in the rest of the yard, when the
				arithmetic mean lead concentration from a composite sample (or arithmetic mean
				of composite samples) of bare soil from the rest of the yard (i.e., non-play
				areas) for each residential building on a property is equal to or greater than
				1,200 parts per million.
4. Clearance levels that are appropriate for
				the purposes of this Section are listed as follows:
a. dust wipes from floors/carpets: less than
				10 micrograms per square foot;
b.
				dust wipes on window sills: less than 100 micrograms per square foot;
c. dust wipes on window troughs: less than
				400 micrograms per square foot;
d.
				dust wipes from exterior surfaces: less than 400 micrograms per square
				foot;
e. lead-contaminated bare
				soil and lead-contaminated covered soil in areas expected to be used by
				children: 400 micrograms per gram; and
f. lead-contaminated covered soil in areas
				where contact by children is less likely or infrequent: 1200 micrograms per
				gram.
5. If using X-ray
				Fluorescence Spectroscopy (XRF) to test for the presence of lead-based paint,
				XRF shall be used according to the manufacturer's procedures. The XRF must be
				licensed in accordance with the department's Radiation Protection Regulations
				(LAC 33:XV).
