|Lead Based Paint||
paint or other surface coatings that contain an amount of lead equal to or greater than 0.7 milligrams per square centimeter (0.7 mg/cm2) or equal to or greater than 0.5% by weight.
|Lead Containing Paint||
paint or other surface coatings that contain lead in an amount equal to or greater than 0.06% lead dry weight (600 ppm) but does not meet the definition of Lead Based Paint. In the absence of paint chip or surface coating bulk sample results, any surface coating shall be assumed to be above 0.06% lead dry weight (600 ppm) until surface coating samples are collected and analyzed that indicate otherwise. Lead concentration shall be determined by a method that has an accuracy of not less than plus or minus 25% at 0.06% lead dry weight, to a confidence level of 95%.
|Lead Contaminated Dust||
dust that contains an amount of lead equal to, or greater than, forty micrograms per square foot (40 ïg/ft2) for interior floor surfaces; two hundred and fifty micrograms per square foot (250 ïg/ft2) for interior horizontal window surfaces; and eight hundred micrograms per square foot (800 ïg/ft2) for exterior floor and exterior horizontal window surfaces.
|Lead Contaminated Soil||
bare soil that contains an amount of lead equal to, or greater that four hundred parts per million (400 ppm) in childrenâ€™s play areas or one thousand parts per million (1000 ppm) in all other areas.
deteriorated Lead Based Paint, Lead Contaminated Dust, Lead Contaminated Soil, the disturbance of Lead Based Paint or Presumed Lead Based Paint without containment, or any other operation that may result in persistent and quantifiable lead exposure.
a surface by surface investigation to determine the presence of Lead Based Paint as described in Chapter 7: Lead Based Paint Inspection, â€œ Guidelines for the Evaluation and Control of Lead Based Paint Hazards in Housing,â€ U.S. Department of Housing and Urban Development, 1997 Revision.
|Lead Related Construction Work||
