Lead Abatement
Appendix D
Appendix D
Glossary of Terms - HUD Regulation
Abatement
– any set of measures designed to permanently eliminate lead-based paint or
lead-based paint hazards. Abatement
includes: (1) the removal of lead-based paint (LBP) and dust-lead hazards, the
permanent enclosure or encapsulation of LBP, the replacement of components or
fixtures painted with LBP, and the removal or permanent covering of soil-lead
hazards; and (2) all preparation, cleanup, disposal, and post abatement
clearance testing activities associated with such measures.
Clearance
examination
– an activity conducted following LBP hazard reduction activities to determine
that the hazard reduction activities are complete and no soil-lead hazards or
settled dust-lead hazards exist in the dwelling unit or worksite.
The clearance process includes a visual assessment and collection and
analysis of environmental samples.
Environmental
intervention blood lead level
– a confirmed concentration of lead in whole blood equal to or greater than 20
mcg/dL for a single test or 15-19 mcg/dL in two tests taken at least 3 months
apart.
Evaluation
– a risk assessment, a lead hazard screen, a LBP inspection, paint testing, or
a combination of these to determine the presence of LBP hazards or LBP.
Hazard
reduction
– measures designed to reduce or eliminate human exposure to LBP hazards
through methods including interim controls or abatement or a combination of the
two.
Interim
controls
– a set of measures designed to reduce temporarily human exposure or likely
exposure to LBP hazards. Interim
controls include but are not limited to repairs, painting, temporary
containment, specialized cleaning, clearance, ongoing LBP maintenance
activities, and the establishment and operation of management and resident
education programs.
Lead-based
Paint Hazard
– any condition that causes exposure to lead from dust-lead hazards, soil-lead
hazards, or LBP that is deteriorated or present in chewable surfaces, friction
surfaces, or impact surfaces, and that would result in adverse human health
effects.
Lead-based
Paint Inspection
– a surface-by-surface investigation to determine the presence of LBP and the
provision of a report explaining the results of investigation.
Lead
Hazard Screen
– a limited risk assessment activity that involves paint testing and dust
sampling analysis, and soil sampling and analysis.
Paint
Stabilization
– repairing any physical defect in the substrate of a painted surface that is
causing paint deterioration, removing loose paint and other material from the
surface to be treated, and applying a new protective coating or paint.
Risk
Assessment
- (1) an on-site investigation to determine the existence, nature, severity, and
location of LBP hazards; and (2) the provision of a report by an individual or
firm conducting a risk assessment explaining the results of the investigation
and options for reducing LBP hazards.
Soil-lead
Hazards
– bare soil on residential property that contains lead equal to or exceeding
levels promulgated by the U.S. Environmental Protection Agency pursuant to
section 403 of the Toxic Substances Control Act or, if such levels are not in
effect, the following levels: 400
mcg/mg in play areas; and 2000 mcg/mg in other areas with bare soil that total
more than 9 square feet per residential property.
Standard
Treatments –
a series of hazard reduction measures designed to reduce all LBP hazards in a
dwelling unit without the benefit of a risk assessment or other evaluation.
Visual Assessment – looking for, as applicable: (1) deteriorated paint; (2) visible surface dust, debris, and residue as part of a risk assessment or clearance examination; or (3) the completion or failure of a hazard reduction measure
