(a) To allow lead dust to settle, the final inspection and clearance testing shall begin no sooner than one hour after the final cleaning is completed.
(b) The final inspection shall consist of a visual inspection to verify that all abated surfaces have been replaced, painted, or sealed, and the collection of environmental samples to ensure that the work area has been effectively cleaned.
(c) Single surface samples, which shall consist of one sample in a single, hard, rinsable container, shall be required for all abatement projects.
(d) Composite clearance samples, which shall consist of no more than four subsamples in a single container, are allowed for abatement projects where similar lead hazard control treatments were used in multiple rooms of the same dwelling. Composite sampling shall be performed in accordance with 5:17-3.4(c).
(e) The following lead dust levels are acceptable for clearance:
(f) The following lead dust levels are acceptable for clearance at residential buildings and child occupied facilities:
(g) Random sampling is permitted in multifamily buildings with 10 or more dwelling units where the units are similarly configured and have had comparable lead control activity, performed at the same time and using the same abatement contractor. The units to be tested shall not be selected until all abatement activity and cleaning have been completed.
