Section 845.280  Guidelines for Abatement and Mitigation of Lead-Contaminated Soil

a)         Soil abatement, including removal of lead-contaminated soil, shall be conducted in accordance with methodologies outlined in Section 845.15 and meet the following requirements;

1)         All soil removal work shall be conducted by licensed lead abatement contractors employing licensed lead workers who are supervised by a licensed lead supervisor;

2)         Worker protection shall be provided as required in Section 845.260.  At a minimum, all workers removing leaded soil shall be provided with a changing area equipped with a facility for washing or showering.  Workers shall be required to change into personal protective clothing before entering the work area, and to remove personal protective clothing and shower or wash before leaving the work area;

3)         A Work Practice and Occupant Protection Program as required by Section 845.255 shall be developed;

4)         Equipment decontamination procedures shall be employed to prevent the spread of lead contamination.  Disposable items are not to be reused and shall be discarded as provided in Section 845.285.  The equipment decontamination procedures shall be outlined in the Work Practices and Occupant Protection Program required by Section 845.255;

5)         Prior to beginning soil removal, the source of the lead contamination of the soil shall be identified and eliminated if possible, to prevent re‑contamination of the abated area;

6)         Removal of the lead-contaminated soil shall be accompanied by dust suppression methods to keep the generation of dust to a minimum;

7)         Soil that is stockpiled prior to disposal shall be:

A)        Placed on a layer of impermeable plastic;

B)        Kept moist to avoid dust generation; and

C)        Covered with impermeable plastic that is secured to the ground.

8)         Removed lead-contaminated soil shall be transported to disposal areas in sealed containers or in a covered vehicle in accordance with disposal requirements outlined in Section 845.290.  Off-site vehicular or foot tracking of contaminated soil shall be avoided;

9)         Any removed soil that is to be replaced shall be replaced with soil that has been tested and confirmed to have a lead concentration less than 400 ppm. The testing shall be conducted by a licensed lead inspector or lead risk assessor, with analysis performed by an accredited laboratory as defined in Section 845.20.

b)         Soil abatement, including the installation of a permanent cover, such as concrete or asphalt, over lead-contaminated soil shall be conducted in accordance with methodologies outlined in Section 845.15 and shall meet the following requirements:

1)         Soil abatement work, including the installation of a permanent cover, may be conducted by non-licensed persons, provided that the abatement activities do not involve removal of the existing lead-contaminated soil;

2)         Dust suppression methods shall be employed to keep the generation of dust to a minimum;

3)         Equipment decontamination procedures shall be employed to prevent the spread of lead contamination.  Disposable items are not to be reused and shall be discarded as provided in Section 845.290;

4)         Prior to beginning soil covering, the source of the lead contamination of the soil shall be identified and eliminated, if possible, to prevent re-contamination of the work area.

c)         Soil mitigation, including the installation of a non-permanent cover, such as mulch, stone, gravel, soil, sod, etc., over lead-contaminated soil shall be conducted in accordance with documented methodologies outlined in Section 845.15 and shall meet the following requirements:

1)         Soil mitigation work, including the installation of a non-permanent cover, may be conducted by non-licensed persons, provided that the mitigation activities do not include the removal of the existing lead-contaminated soil;

2)         Dust suppression methods shall be employed to keep the generation of dust to a minimum;

3)         Equipment decontamination procedures shall be employed to prevent the spread of lead contamination.  Disposable items are not to be reused and shall be discarded as provided in Section 845.290;

4)         Prior to beginning soil mitigation, the source of the lead contamination of the soil shall be identified and eliminated if possible to prevent re-contamination of the mitigation area;

5)         The non-permanent cover material shall be tested and confirmed to have a lead concentration less than 400 ppm. The testing shall be conducted by a licensed lead inspector or lead risk assessor, with analysis conducted by an accredited laboratory.
