A firm working on a property that is already contaminated with paint chips, dust, debris and residue must proceed by containing the work area for the renovation, and complying with all cleaning requirements under the Rule for that work area.  Paint chips, dust, debris and residue that fall within the work area must be eliminated.  If paint chips, dust and debris exist beyond the work area, but were not a product of the firm's window replacement activities, EPA recommends that the firm document and keep record of the conditions.
