Current through Register Vol. 46, No. 28, July 10, 2024
The following Phase II abatement procedure modifications
						shall apply for building/structures planned for demolition. All ACM, PACM or
						asbestos material must be removed from a building/ structure and the asbestos
						project complete, prior to commencement of demolition activities.
(a)
Air sampling and analysis.
Air sampling and analysis on an asbestos projects
						conducted under this section shall be conducted in accordance with the
						requirements of Subpart 56-4 of this Part.
(b)
Regulated abatement work area
					 preparation.
Regulated abatement work area preparation shall be as per
						Subpart 56-7 of this Part, except as follows:
(1) Timing-removal of salvage. Objects that
					 can be removed from the regulated abatement work area without disturbing
					 friable ACM prior to beginning Phase II B abatement procedures shall be
					 completed as follows. The removal of nonporous, movable or non-movable salvage
					 shall occur after critical barriers, isolation barriers and decontamination
					 enclosures are in place in that portion of the building or structure, and only
					 after salvage has been wet-cleaned and HEPA-vacuumed.
(2) Floor, wall and ceiling plasticizing and
					 sealing. All porous floor, wall and ceiling surfaces, except where abatement of
					 ACM, PACM or asbestos material shall be performed on those specific surfaces,
					 shall be covered with one layer of, at a minimum, six mil fire-retardant
					 plastic sheeting. The floor shall be plasticized first, and its plastic
					 sheeting shall extend up the walls a distance of at least 12 inches on all
					 sides. The walls shall then be plasticized by applying plastic sheeting from
					 the ceiling to the floor, overlapping the floor sheeting by at least 12 inches.
					 Next, the ceiling shall be plasticized, overlapping the walls by at least 12
					 inches, to form a secure airtight seam. If the floor surface is not to be
					 plasticized, it shall be made watertight. All seams in the plastic shall be
					 sealed watertight and airtight.
(3)
					 Suspended ceilings. Suspended ceiling tiles and T-grid components in proximity
					 to friable ACM shall remain in place until the regulated abatement work area
					 has been fully prepared in accordance with this section, and electrical and
					 HVAC systems have been shut down. These potentially contaminated suspended
					 ceiling components shall be removed at the completion of the remaining work
					 area preparation, including establishment of negative air ventilation systems,
					 prior to commencement of Phase II B activities. These removed ceiling
					 components shall be bagged/containerized and disposed of as asbestos waste.
					 Critical barriers shall be installed above the suspended ceiling as per section
					 56-7.11(a) 
					 of this Part, prior to the commencement of Phase II B abatement.
(4) Elevators. Elevators running through the
					 regulated abatement work area shall conform to the following:
(i) The elevator door in the regulated
					 abatement work area shall be enclosed per section
					 56-7.11(d) 
					 of this Part.
(ii) Elevators not
					 remaining in use shall have the fuses removed and the power switch locked in
					 the open position.
(iii) Elevator
					 shafts shall not be used as waste chutes for asbestos waste material.
(iv) Elevators that remain in use shall
					 conform to the additional procedures to minimize the piston effects.
(a) Elevator controls shall be modified to
					 bypass the regulated abatement work area.
(b) A third (final) layer of polyethylene is
					 to be duct taped airtight but with slack so as to form a larger perimeter
					 diaphragm. Air leakage across the barrier shall be corrected upon discovery,
					 and the elevator shaft shall be checked for airborne asbestos contamination. If
					 contamination is found in this area, the entire affected area shall be
					 wet-cleaned prior to continuing any other work.
(c) This system shall be smoke tested
					 daily.
