Each owner or operator of a demolition or renovation that contains regulated asbestos in excess of 10 square feet and/or 16 linear feet shall comply with the following procedures:
1. Remove all regulated asbestos containing material from a facility being demolished or renovated before any activity begins that would break up, dislodge, or similarly disturb the material or preclude access to the material for subsequent removal. Regulated asbestos containing material does not have to be removed before demolition if:
a. It is Category I non-friable asbestos containing material that is not in poor condition and is not friable.
b. It is on a facility component that is encased in concrete or other similarly hard material and is adequately wet whenever exposed during demolition.
c. It is not accessible for testing and was, therefore, not discovered until after demolition began and, as a result of the demolition, the material cannot be safely removed. If not removed for safety reasons, the exposed RACM and any asbestos-contaminated debris must be treated as asbestos-containing waste material and adequately wet at all times until disposed of.
d. It is Category II non-friable asbestos containing material and the probability is low that the materials will become crumbled, pulverized, or reduced to powder during demolition.
2. When a facility component that contains, is covered with, or is coated with regulated asbestos containing material is being taken out of the facility as a unit or in sections:
a. Adequately wet all regulated asbestos containing material exposed during cutting or disjoining operations.
b. Carefully lower each unit or section to the floor and to ground level, not dropping, throwing, sliding, or otherwise damaging or disturbing the regulated asbestos containing material.
3. When regulated asbestos containing material is stripped from a facility component while it remains in place in the facility, adequately wet the regulated asbestos containing material during the stripping operation.
a. In renovation operations-wetting is not required if a local exhaust ventilation and collection system is used, a glove-bag system is used, or a leak-tight wrapping system is used.
4. After a facility component covered with, coated with, or containing regulated asbestos containing material has been taken out of the facility as a unit or in sections, it shall be contained in leak-tight wrapping.
5. For large facility components such as reactor vessels, large tanks, and steam generators, the regulated asbestos containing material is not required to be stripped if the following requirements are met:
a. The component is removed, transported, stored, disposed of, or reused without disturbing or damaging the regulated asbestos containing material.
b. The component is encased in a leak-tight wrapping.
c. The leak-tight wrapping is labeled during all loading and unloading operations and during storage.
6. For all regulated asbestos containing material, including material that has been removed or stripped:
a. Adequately wet the material and ensure that it remains wet until collected and contained or treated in preparation for disposal.
b. Carefully lower the material to the ground and floor, not dropping, throwing, sliding, or otherwise damaging or disturbing the material.
c. Transport the material to the ground via leak-tight chutes or containers if it has been removed or stripped more than 50 feet above ground level and was not removed as units or in sections.
7. Third party continuous monitoring is required during removal of all ACM if the building is occupied. (Monitoring is not required for demolitions) Final air clearance is required after ACM removal if the building is occupied or will be occupied at a later date. (Final air clearance is not required for demolitions)
8. The person who conducts the demolition of unsafe buildings or parts of buildings containing asbestos, may proceed with the demolition until it is safe for the certified asbestos inspector to take representative samples of debris. It must be assumed that the debris contains regulated asbestos, unless it can be proven through sampling that the debris or parts of the debris have asbestos content of 1% or less. If parts of the debris are 1% or less, and other parts are greater than 1%, and the various debris can be safely separated, then only those areas of debris greater than 1% regulated asbestos must be specially handled. The following procedures on those portions of the buildings that pose imminent danger to public health or safety, or both shall be used:
a. The person shall ensure that the debris is wet at all times and stays wet until disposed. The person shall ensure that the project activities generate no visible emissions.
b. The person shall ensure that on site at all times during the demolition is a registered contractor supervisor, who is considered a competent person.
9. For emergency demolitions being conducted under an order of a state or local government agency:
a. Adequately wet the portion of the facility that contains regulated asbestos containing material during the wrecking operation.
b. In all such cases where there is uncertainty as to the regulated asbestos in the facility, it should be assumed that it contains regulated asbestos until such time that a certified asbestos inspector can obtain representative samples can be taken of the debris to ascertain if greater than 1% regulated asbestos content is present.
c. A registered contractor supervisor must be on site at all times.
