N.J. Admin. Code § 5:17-9.1

Current through Register Vol. 56, No. 23, December 2, 2024

Section 5:17-9.1 - Final inspection and clearance testing

(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.

1. Wipe samples shall be taken from the abated area, one sample from within 10 feet outside the containment area and one sample from any nearby high traffic area.

2. When an abatement project involves exterior abatement work, soil samples shall be collected around the foundation of the structure and in any play areas that could have been affected by the work. All soil samples shall be composite samples as described in (d) below.

(c) Single surface samples, which shall consist of one sample in a single, hard, rinsable container, shall be required for all abatement projects.

1. Single surface sampling shall follow the methodology at 5:17-3.3(d) of this chapter.

2. Single surface sampling shall comply in number and location with Table 9.1 below.

(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:

1. Floors--100 [mu] g/square foot;

2. Interior window sills--500 [mu] g/square foot; and

3. Window wells, exterior concrete, rough surfaces--800 [mu] g/square foot.

(f) The following lead dust levels are acceptable for clearance at residential buildings and child occupied facilities:

1. Floors--less than 10 µg/square foot;

2. Interior window sills--less than 100 µg/square foot;

3. Window wells--less than 400 [mu] g/square foot.

(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.

(h) Field spiked samples shall be submitted and analyzed in accordance with the requirements of 5:17-3.3(d).

(i) All clearance samples shall be analyzed at a laboratory participating in the NLLAP program or an equivalent independent national accreditation program.
