Section 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:

(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:

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

(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).

(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 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.

(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.

(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:

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

(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.

(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.

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

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

2. The owner or operator uses one of the following emission control methods:

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.

b. A glove-bag system designed and operated to contain the particulate asbestos material produced by the stripping of the asbestos materials.

c. Leak-tight wrapping to contain all RACM prior to dismantlement.

(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).

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

(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:

(a) Adequately wet the RACM during stripping; or

(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.

(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:

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

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

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

(6) For all RACM, 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 in accordance with s. NR 447.13; and

(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.

(d) RACM contained in leak-tight wrapping that has been removed in accordance with subs. (3) (a) 2. c. and (4) need not be wetted.

(7) When the temperature at the point of wetting is below 0°C (32°F):

(a) The owner or operator need not comply with sub. (2) (a) and the wetting provisions of sub. (3).

(b) The owner or operator shall remove facility components containing, coated with, or covered with RACM as unit or in sections to the maximum extent possible.

(c) During periods when wetting operations are suspended due to freezing temperatures, the owner or operator shall record the temperature in the area containing the facility components at the beginning, middle and end of each working day and keep daily temperature records available for inspection by the department during normal business hours at the demolition or renovation site. The owner or operator shall retain the temperature records for at least 2 years.

(8) No RACM may be stripped, removed or otherwise handled or disturbed at a facility regulated by this chapter unless at least one on-site representative, such as a foreman or management-level person or other authorized representative, trained in the provisions of this chapter and the means of complying with them, is present. Every 2 years, the trained on-site individual shall receive refresher training in the provisions of this chapter. The required training shall include at a minimum: applicability; notifications; material identification; control procedures for removals including, at least, wetting, local exhaust ventilation, negative pressure enclosures, glove-bag procedures, and High Efficiency Particulate Air (HEPA) filters; waste disposal work practices; reporting and recordkeeping; and asbestos hazards and worker protection. Each owner or operator shall post evidence that the required training has been completed and make such evidence available for inspection by the department at the demolition or renovation site.

(9) For facilities described in s. NR 447.06(2) (c), adequately wet the portion of the facility that contains RACM during the wrecking operation.

(10) If a facility is demolished by intentional burning, all RACM including Category I and Category II nonfriable ACM shall be removed in accordance with this chapter before burning.
