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 56-7.10 of this Part, except that six air changes per hour are required within the work area.
3. (3) Critical and isolation barriers. Prior to the placement of critical and isolation barriers, affected surfaces shall be pre-cleaned using HEPA-filtered vacuum equipment and wet cleaning methods. All critical and isolation barriers shall be installed as per section 56-7.11(a)-(b) 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) Removal of mounted objects and elevator isolation. Regulated abatement work area preparation shall also comply with section 56-7.11(c)-(d) of this Part.

5. (5) Plasticizing. The ceiling, walls and floor need not be plasticized as per section 56-7.11(e) of this Part for manual or chemical removal methods.

   (c) Removal.

   Removal of 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 shall be consistent with section 56-9.1(b) of this Part, with the exception that lockdown encapsulant shall only be applied to non-removal surfaces covered with fire-retardant plastic sheeting.

   (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 removal of non-friable asbestos- containing flooring and/or mastic materials including cove base and associated mastic. (Note: Full work area preparation, attached decontamination system enclosures, abatement and multiple cleanings per this Part are required for beadblaster use or other abrasive abatement method.)

(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.
