A substance that forms a barrier between lead-based paint and the
environment using a liquid-applied coating (with or without reinforcement
materials) or an adhesively bonded covering material. (40 CFR 745.223)
Enclosure
The use of rigid, durable construction materials that are mechanically fastened
to the substrate in order to act as a "dust tight" barrier between lead-based
paint and the environment. (40 CFR 745.223)

(LBP)
milligrams per square centimeter or more than 0.5 percent (5000ug/g or 5000
ppm) by weight. (40 CFR 745.223)

Hazard

present in accessible surfaces, friction surfaces, or impact surfaces that would
result in adverse human health effects.
Lead-Contaminated
Surface dust that contains an area or mass concentration of lead at or in
Dust
excess of levels defined in Table A-1 of this SOW.
Lead-Contaminated
Bare soil that contains lead at or in excess of levels defined in Table A-1 of

this SOW.
Lead Hazard Control
In residential lead-based paint hazard control work, any method designed to
Treatment
control lead-based paint hazards. Treatment includes interim controls,
abatement, and removal. Examples include paint film stabilization, friction and
impact surface treatments, dust removal using standardized cleaning
techniques, soil covers, building component replacement, enclosure, paint
removal, or soil removal.
g/ft2
Micrograms per square foot
g/g
Micrograms per gram (parts per million on mass/mass basis)
MS/MSD

Permanently Covered
Soil which has been separated from human contact by the placement of a
Soil
barrier consisting of solid, relatively impermeable materials, such as pavement
or concrete. Grass, mulch, and other landscaping materials are not
