a. The surface area of the asbestos material which will be disturbed during the installation of hangers, brackets or other enclosure supports shall first be sprayed with amended water using a low-pressure airless spray;

b. Power drills used to install anchors or other tools which may disturb asbestos material shall be equipped with or used in conjunction with HEPA-vacuum systems;

c. Loose asbestos materials shall be removed while damp and disposed of in accordance with Section VI.C.7. of these Regulations;

d. After the installation of hangers, brackets or other supports and before the asbestos material is enclosed, asbestos-containing materials shall be repaired, using materials which do not contain asbestos;

e. Enclosures for asbestos materials shall be identified by signs, labels, color coding or some other mechanism approved by the Department to warn persons who may be required to disturb the enclosure, that asbestos is present; and

f. Enclosures shall be inspected at least annually to ensure their integrity.

a. As asbestos materials are removed, they shall be thoroughly wetted and placed into six (6)-mil plastic disposal bags;

b. Asbestos-contaminated materials such as plastic sheeting, clothing, and other items shall be placed into six (6)-mil plastic disposal bags;

c. Plastic disposal bags containing asbestos and asbestos-contaminated materials shall be sealed, cleaned, and, while being removed from the work area, placed into approved six (6)-mil plastic disposal bags, which shall be sealed, labeled, and transported directly to an approved waste disposal , storage, or transfer facility, in accordance with the applicable Pennsylvania Department of Environmental Resources, and EPA regulations;

d. Any asbestos-contaminated materials which may penetrate the asbestos disposal bags shall be placed into fiber drums, which shall be sealed and labeled in accordance with applicable EPA regulations;

e. There shall be no visible emission of asbestos dust during the transport of asbestos or asbestos-contaminated waste; and

f. Large structural or mechanical components may be removed with the attached asbestos material for disposal provided:

a. After all asbestos abatement work has been completed, but before the plasticizing is removed, wet wipe all surfaces in the work area to eliminate gross debris and then remove the top layer of plastic sheeting.

b. All surfaces within the work area from which asbestos material has been removed, and the bottom layer of plastic sheeting shall be HEPA-vacuumed and where feasible, wet cleaned with amended water;

c. Following thorough cleaning, and after the Certified Asbestos Project Inspector has confirmed that the no visible residue remains, all surfaces in the work area from which asbestos has been removed and the bottom layer of plastic sheeting shall be sprayed where feasible with an encapsulant;

d. Clearance sampling shall be conducted in accordance with Section VI.D.4.c. after the bottom layer of plastic sheeting on walls, floors, and objects in the work area has dried and has been removed;

e. The sequence of wet and dry cleaning shall be repeated in twenty-four (24) hour intervals until the Certified Asbestos Project Inspector has determined that no residue is visible and, based on aggressive air monitoring conducted after all surfaces have dried, the airborne asbestos levels do not exceed the re-occupancy standard set forth in Section VI D.5. of these Regulations.

f. Critical barriers shall remain in place until the requirements of paragraph e. above has been satisfied.

No structural or mechanical surfaces from which asbestos has been removed shall be re-insulated with asbestos materials.

a. Pre-Test Samples

The purpose of collecting pre-test air samples is to establish baseline levels of airborne asbestos fibers in those areas in which asbestos abatement work is to be conducted and in those areas immediately adjacent to the asbestos abatement work areas. Pre-test sample results are compared to project sample results to determine if asbestos has escaped from the asbestos abatement work areas;
