1. (1) Establishment of regulated abatement work areas. Each regulated abatement work area shall be established and signage posted as per the requirements of section 56-7.4 of this Part. Each regulated abatement work area shall remain vacated except for certified workers until satisfactory clearance air sampling results have been obtained or the asbestos project is complete.

2. (2) Preliminary preparation. Regulated abatement work area preparation shall also comply with sections 56-7.1 through 56-7.11(d) of this Part.

   1. (i) Exception. For exterior regulated abatement work areas with ACM, PACM or asbestos material intact, establishment of negative air systems as per section 56-7.8 of this Part, and installation of isolation barriers as per section 56-7.11(b) of this Part is not required. Remote personal decontamination system enclosures are allowed for exterior regulated abatement work areas.
3. (3) Critical barriers. Prior to the placement of critical barriers, affected surfaces shall be pre-cleaned using HEPA-filtered vacuum equipment and wet cleaning methods. All critical barriers shall be installed as per section 56-7.11(a) of this Part and all seams of HVAC or other system components that pass through a regulated abatement work area shall be sealed prior to beginning Phase II B work for each regulated abatement work area on the project. The critical and isolation barriers shall be removed only after satisfactory clearance air sampling results have been obtained.

4. (4) Limitations. Full regulated abatement work area negative pressure enclosure preparation as per section 56-7.11(a), (b) and (e) of this Part is not required if the following removal conditions are followed:

   1. (i) The ACM, PACM or asbestos material must be intact, and the wetted pipe/duct/conduit shall be wrapped in two independent layers of at least six mil fire-retardant plastic sheeting and sealed airtight.
   2. (ii) A one-layer dropcloth of at least six mil fire-retardant plastic sheeting shall be utilized below the ACM, PACM or asbestos material during all wrapping operations.

   3. (iii) Insulation removals to allow for cuts of pipe/duct/conduit and cuts for removal of ACM pipe/duct/conduit or sections thereof shall be performed using glovebag procedures within a negative pressurized tent enclosure, per section 56-8.4(a) of this Part.

      (c) Removal.

      Removal of the wrapped ACM and asbestos material shall proceed as per the requirements of Subpart 56-8 of this Part.

      (d) Final cleaning and clearance procedures.

      Final clean-up and clearance procedures for abatement shall comply with Subpart 56-9 of this Part, except that only one stage of cleaning (final) is to be performed. Lockdown encapsulant use is not required, except as indicated for glovebag procedures.

      (e) Final waste removal from the site.

      The requirements of Subpart 56-10 of this Part shall apply, once all asbestos project regulated abatement work areas have been completed.

The following Phase II abatement procedures shall apply for wrap and cut removal of asbestos- containing or ACM covered abandoned pipes/ducts/conduits. All other requirements of this Part shall apply:

(a) Air sampling and analysis.

Air sampling and analysis on an asbestos project 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.
