NR 447.08 NR 447.08 Demolition and renovation; procedures for asbestos emission control. Each owner or operator of a demolition or renovation activity to whom this section applies, according to s. NR 447.06, shall comply with the following procedures:

NR 447.08(1) (1) Remove all RACM 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. RACM need not be removed before demolition if any of the following apply:

NR 447.08(1)(a) (a) It is Category I nonfriable ACM that is not in poor condition and is not friable.

NR 447.08(1)(am) (am) Removal of category I roofing shall meet the specifications in the Interpretive Rule Governing Roof Removal Operations, 40 CFR part 61, Appendix A to Subpart M, incorporated by reference in s. NR 484.04 (21s).

NR 447.08(1)(b) (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.

NR 447.08(1)(c) (c) It was 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 shall be treated as asbestos-containing waste material and adequately wet at all times until disposed of.

NR 447.08(1)(d) (d) It is Category II nonfriable ACM and the probability is low that the materials will become crumbled, pulverized or reduced to powder during demolition.

NR 447.08(2) (2) When a facility component that contains, is covered with or is coated with RACM is being taken out of the facility as a unit or in sections:

NR 447.08(2)(a) (a) Adequately wet all RACM exposed during cutting or disjoining operations; and

NR 447.08(2)(b) (b) Carefully lower each unit or section to the floor and to ground level, not dropping, throwing, sliding or otherwise damaging or disturbing the RACM.

NR 447.08(3) (3) When RACM is stripped from a facility component while it remains in place in the facility, adequately wet the RACM during the stripping operation.

NR 447.08(3)(a) (a) In renovation operations, wetting is not required if:

NR 447.08(3)(a)1. 1. The owner or operator has obtained prior written approval from the department based on a written application that wetting to comply with this subsection would unavoidably damage equipment or present a safety hazard; and

NR 447.08(3)(a)2. 2. The owner or operator uses one of the following emission control methods:

NR 447.08(3)(a)2.a. a. A local exhaust ventilation and collection system designed and operated to capture the particulate asbestos material produced by the stripping and removal of the asbestos materials. The system shall exhibit no visible emissions to the outside air or be designed and operated in accordance with the requirements in s. NR 447.15.

NR 447.08(3)(a)2.b. b. A glove-bag system designed and operated to contain the particulate asbestos material produced by the stripping of the asbestos materials.

NR 447.08(3)(a)2.c. c. Leak-tight wrapping to contain all RACM prior to dismantlement.

NR 447.08(3)(b) (b) In renovation operations where wetting would result in equipment damage or a safety hazard, and the methods allowed in par. (a) cannot be used, another method may be used after obtaining written approval from the department based upon a determination that it is equivalent to wetting in controlling emissions or to the methods allowed in par. (a).

NR 447.08(3)(c) (c) A copy of the department’s written approval shall be kept at the work site and made available for inspection.

NR 447.08(4) (4) After a facility component covered with, coated with or containing RACM has been taken out of the facility as a unit or in sections pursuant to sub. (2), it shall be stripped or contained in leak-tight wrapping, except as described in sub. (5). If stripped, either:

NR 447.08(4)(a) (a) Adequately wet the RACM during stripping; or

NR 447.08(4)(b) (b) Use a local exhaust ventilation and collection system designed and operated to capture the particulate asbestos material produced by the stripping. The system shall exhibit no visible emissions to the outside air or be designed and operated in accordance with the requirements in s. NR 447.15.

NR 447.08(5) (5) For large facility components such as reactor vessels, large tanks and steam generators, but not beams, which shall be handled in accordance with subs. (2) to (4), the RACM is not required to be stripped if the following requirements are met:

NR 447.08(5)(a) (a) The component is removed, transported, stored, disposed of or reused without disturbing or damaging the RACM.

NR 447.08(5)(b) (b) The component is encased in a leak-tight wrapping.

NR 447.08(5)(c) (c) The leak-tight wrapping is labeled according to s. NR 447.12 during all loading and unloading operations and during storage.

NR 447.08(6) (6) For all RACM, including material that has been removed or stripped:

NR 447.08(6)(a) (a) Adequately wet the material and ensure that it remains wet until collected and contained or treated in preparation for disposal in accordance with s. NR 447.13; and
