(1) The Board shall establish by regulation standards for minor and small asbestos projects in order to protect the health and safety of occupants of private residences and buildings and the general public by preventing the dispersal of asbestos fibers through the building, private residences, or into the environment. Such minor and small asbestos project standards shall include, but shall not be limited to, the following requirements:
(a) Work Area Preparation.
(.1) Appropriate caution signs shall be posted at all entrances to the asbestos project work area and the waste storage area at all times during the asbestos project until the re-occupancy standard has been met.
(.2) All furniture, equipment, fixtures, and other movable objects shall be HEPA-vacuumed and, where feasible, wet-cleaned and removed from the work area.
(.3) All other objects that cannot be removed shall be HEPA-vacuumed and, where feasible, wet- cleaned and covered with plastic sheeting taped in place.
(.4) Except for small asbestos projects, the work area shall be isolated for the duration of the asbestos project by completely enclosing the work area and sealing off all doors, windows, ducts, and other openings with plastic sheeting taped in place.
(.5) Except for small asbestos projects, all floors, walls, and other surfaces, shall be covered with plastic sheeting, as specified by the major project standards, taped in place.
(.6) A sealable barrier of plastic sheeting shall be constructed at the entrance to the work area.
(.7) All ventilation systems into and out of the work area shall be shut down.
(.8) Occupants shall be removed from any floor where an asbestos project is in progress unless the work area is completely enclosed and sealed off from other areas.
(b) Asbestos Project Procedures.
(.1) General Procedures.
(.a) No person shall enter the work area without proper equipment, clothing, and training.
(.b) The contractor or supervisor shall provide all authorized persons who enter the work area with the same protective clothing and equipment required for major asbestos projects and shall ensure that it is properly used.
(.c) The contractor or supervisor shall ensure that all workers remove asbestos debris from clothing and equipment before leaving the work area.
(.d) The contractor or supervisor shall ensure that appropriate air monitoring to determine worker exposure shall be conducted for asbestos workers not covered by the OSHA Asbestos Standard.
(.2) Other Procedures.
(.a) The contractor or supervisor shall ensure that all removal, enclosure, encapsulation, waste disposal, work area clean-up, and re-insulation procedures required for major asbestos projects are followed.
(.3) Air Monitoring.
(.a) Air monitoring shall be conducted both inside and outside the work area in accordance with the methods and procedures established by the Board.
(.b) Air sampling and analysis shall be conducted according to the latest NIOSH or EPA method for phase contrast or electron microscopy, if a standard NIOSH or EPA protocol has been established.
(.c) Air samples shall be analyzed by an independent certified laboratory by appropriate analytic methods.
(.d) The asbestos contractor or supervisor shall immediately halt asbestos work and implement appropriate remedial measures if air testing results show any increase in airborne asbestos levels outside the work area which exceeds the standard set for major asbestos projects.
(.e) The Board shall establish a re-occupancy standard setting a maximum airborne asbestos level no higher than one one-hundredth (.01) fibers per cubic centimeter of air or the ambient level outside the building, whichever is greater.
(.f) After final clean-up, the asbestos project work area, including any part of the building evacuated during an asbestos project, shall not be unsealed or re-occupied until air testing results show that airborne asbestos levels do not exceed the re-occupancy standard.
(.4) The asbestos project work area, including any part of the building evacuated during an asbestos project, shall not be unsealed or re-occupied until the contractor or supervisor certifies that:
(.a) based on a visual inspection, the area contains no visible dust or debris; and
(.b) based on the results of aggressive air monitoring, the airborne asbestos level in the area does not exceed the re-occupancy standard.
(.5) Alternate Standards.
(.a) The Board may establish by regulation alternate standards for renovation, repair, and demolition projects involving non-friable asbestos materials that may be rendered friable by project activity, and for projects involving the repair or enclosure of friable asbestos materials where the asbestos materials are not disturbed by the process of repair or enclosure.
(2) The Board shall establish by regulation standards for incidental asbestos projects in order to protect the health and safety of occupants of buildings and private residences and the general public by preventing the dispersal of asbestos fibers through the building, private residence or into the environment.
(3) The Department may approve alternative equivalent methods for work area preparation proposed in the permit application if the methods required by this Section are not technically feasible or would cause unsafe or unhealthy conditions. A request to the Department for approval of alternative equivalent methods shall include the reasons for not using the methods required by this Section and a description of the proposed alternative methods. The fee for an application for an alternate method request pursuant to this subsection shall be forty-five dollars ($45). 119
