    v.

    Waste shall be transported in enclosed roll-offs or dumpsters, vehicles that have completely enclosed cargo areas, or four-sided cargo area which shall be completely covered with six mil thick plastic sheeting or other equivalent covering while the waste is being transported. All visible debris remaining in the vehicle cargo area after the waste has been deposited at the disposal area shall be immediately removed by wet cleaning methods and disposed of in accordance with the requirements of subsection 8-9(c)(7)g. If asbestos waste is handled in a rented vehicle, the owner of the vehicle shall be notified that the vehicle will be used to transport asbestos waste.

    h.

    Air sampling.

    1.

    The department shall require final clearance air monitoring for all enclosed asbestos abatement work areas. The department shall require third-party final clearance air monitoring for all asbestos abatement projects of a magnitude of 160 square feet or 260 linear feet or greater conducted in an indoor work area. In-house projects conducted by state-exempted business entities using their own trained employees are exempt from this provision.

    2.

    The department shall require the following air samples:

    i.

    When the department requires third-party air sampling, the samplers will collect samples outside the work area to determined the effectiveness of work practices and control measures used to contain asbestos fibers inside the project area. The air sampling professional will determine the number, frequency and location of the samples. The department may require third party air monitoring on a case-by-case basis for any asbestos abatement project; and

    ii.

    After removal and clean-up activities are complete the owner and asbestos abatement contractor shall ensure that air samplers conduct aggressive air sampling on all projects described in paragraph 8-9(7)h.i. of this Code. Glove bag projects are exempt from aggressive air sampling. Glove bag projects shall employ nonaggressive area sampling during operations.

    3.

    Clearance criteria.

    i.

    An indoor work area of 1000 cubic feet or greater shall be available for reoccupancy when the results of five phase contrast microscopy (PCM) or transmission electron microscopy (TEM) samples are all less than one-hundredth fibers per cubic centimeter (f/cc). The microscopists shall perform PCM according to the National Institute for Occupational Safety and Health (NIOSH) 7400 method or TEM according to the NIOSH 7402 method or an equivalent method approved by the department. If any one of the five samples reveals an airborne fiber count greater than one-hundredth f/cc the asbestos abatement contractor shall clean the area again. Air sampling professionals or their technicians shall conduct aggressive final clearance air sampling again. This process shall continue until the air sampling results are at or below one-hundredth f/cc.

    ii.

    Indoor asbestos abatement work areas of less than 1000 cubic feet shall require two PCM or TEM samples taken from each work area. Both samples must be less than one-hundredth f/cc before the air sampling professional can clear the area for reoccupancy.

    iii.

    If all sample results done on PCM are higher than one-hundredth f/cc, then the air sampling professional may choose to direct the laboratory to perform TEM using the NIOSH 7402 method on the highest sample. If the TEM analysis indicates the asbestos fiber level is less than one-hundredth f/cc, the air sampling professional may clear the area for reoccupancy.

    iv.

    The air sampling professional may request a waiver of the one-hundredth f/cc clearance level required by subparagraphs 8-9(c)(7)h.3.i. through iii. for an asbestos abatement project where the sampler can demonstrate that the background levels exceed the one-hundredth f/cc enforcement level. The department may require the air sampling professional to document that the background interference is from sources not associated with the asbestos abatement project. The background air samples shall be of sufficient number and strategic placement to be acceptable by the department.

    4.

    The asbestos air sampling professional shall have the following responsibilities. Failure to meet those responsibilities may result in decertification. The air sampling professional shall:

    i.

    Utilize trained air sampling technicians;

    ii.

    Assure that the microscopist employs the WIOSH 7400 method when performing PCM on air samples from an asbestos project;

    iii.

    Assure that the microscopist employs the NIOSH 7402 or an equivalent method when performing TEM on non-AHERA air samples; and

    iv.

    Assure that the laboratories utilized have the proper accreditation. The accreditation organizations are the American Industrial Hygiene Association (AIHA) and the National Voluntary Laboratory Accreditation Program (NVLAP). The air sampling professional may utilize persons on the Asbestos Analysts Registry.

    5.

    The contractor and the owner shall keep the air monitoring results for three years. The person shall make the results available to representatives of the department upon request.

If damage occurs to any friable ACM within the work area, the person shall immediately stop the project activities. The person shall thoroughly clean with a HEPA-filtered vacuum or by wet cleaning methods all asbestos-contaminated surfaces. Each individual who is contaminated with asbestos fibers from project activities including clean-up operations shall remove or clean clothing with a HEPA filtered vacuum or by wet cleaning methods before leaving the work area. The person shall notify the department of the date, nature and clean-up measures used for these occurrences before individuals other than those involved in the project occupy the area. The department may require additional cleaning before allowing reoccupation of the area. The person may use mini-containment procedures during glove bag operations if they are necessary to provide increased protection for health and environment.
