Any materials/containers belonging to or under the control of the Contractor found not meeting these requirements will have all deficiencies corrected within 24 hours or the materials will be removed from the installation by the Contractor within the same 24-hour limit. This time limit applies regardless of time of day or day of week, and includes holidays and weekends. All corrective action costs and/or removal costs will be borne by the Contractor.

2.8 Material Safety Data Sheets relating to Government supplied materials, and hazards presented by Government operations at or in the Contractor's job site may be obtained through the Contracting Officer. Requests for information must be provided to the Contracting Officer a minimum of 20 working days prior to the date this information is required.

3. Spill Prevention Plan:

3.1 Equipment fueling operations shall, at all times, be observed. Fueling equipment shall be operated in accordance with manufacturer guidance and accepted industry standards.

Environmental Protection/Borrow Pit Plan: At 65% design review or prior to project groundbreaking, whichever comes first, the contractor shall submit an environmental protection/borrow pit plan to the Contracting Officer which covers the requirements of all waste disposal, borrow pit, and project site operations. This plan shall include, but not be limited to, the use of on-base waste disposal sites, the name and location of off-base disposal sites, methods used to safely and legally transport wastes to all disposal sites, borrow pits to be used, borrow pit development, methods used to prevent erosion and other non-point source pollution at the project site (including a contingency plan for effectively handling spills of hazardous materials), and training for employees on all elements of this plan. No on-site work, to include mobilization, staging, and site preparation, shall be permitted prior to this plan's approval by the Contracting Officer. The contractor shall comply with all applicable environmental laws and regulations and specific requirements stated elsewhere in the contract specifications. Ignorance of environmental regulations shall not be acceptable cause for contractor non-compliance. AN EXAMPLE ENVIRONMENTAL PROTECTION/BORROW PIT PLAN IS AVAILABLE FROM THE CONTRACTING OFFICER.

6. Site Control:

6.1 Contractor shall establish, demarcate and restrict access to, regulated areas per 8 AAC 05.045 (f).

6.2 Contractor shall post warning signs per 8 AAC 05.045 (m)(1).

6.3 General: Engineering controls are required in abatement areas to reduce fiber concentrations in the work area for worker protection and to prevent escape of particulates from the work area during abatement work. The Owner's Representative must approve the installation of all engineering controls before abatement work begins. The Contractor will remove engineering controls only when final clearance has been achieved.

6.4 Containment Areas: The Contractor shall establish containment areas within the abatement areas as described in Appendix F to 8 AAC 05.045 , sufficient to isolate the abatement work area from the occupied portions of the building.

6.5 Exhaust Ventilation: The Contractor shall provide high-efficiency, filtered exhaust ventilation sufficient to provide a minimum of four air changes per hour (ACPH) and sufficient to maintain a minimum air gauge pressure in each containment area of -0.02 inches water column. Exhaust air shall be ducted to the outdoors. Volumetric flow rates and pressure differentials will be measured by the Owner's Representative prior to approval of final project set-up.

6.6 Preliminary cleaning is intended to remove gross debris from the space in order to avoid its disturbance as workers move through the area, removing insulation from pipes. Prior to beginning removal of asbestos from pipes, the Contractor shall clear loose gross debris, asbestos debris piles and insulation chunks and other debris from the space using a HEPA filtered vacuum, disposal bag, and wet methods. It is not necessary to preclean the space of all dust.

6.7 Preliminary cleaning should be used when removing asbestos containing tiles, sheetrock, mastic, duct insulation, or any asbestos containing building material when there is gross loose debris in the area.

6.8 Contractor shall use work practices such as HEPA vacuums and wet methods as called for in Appendix F to 8 AAC 05.045, as necessary to remove debris, to prevent the spread of any released fibers, and to maintain acceptable worker-breathing-zone fiber air concentrations.

6.9 Workers shall not disturb dry materials, except to vacuum them up.

6.10 Contractor shall shut down hot piping in advance of abatement procedures to allow piping to cool sufficiently for handling

6.11 Asbestos-containing materials shall be saturated with a wetting agent or removal encapsulant before removal from structures. Materials shall be removed carefully in pieces as large as possible and bagged immediately before they can dry out.

6.12 Insulated fittings on runs of fiberglass-insulated piping shall be removed by cutting piping on either side of the fitting and disposing of the fitting and insulation intact as a unit, where ever possible. If the insulation is damaged or unencapsulated, it shall be treated with asbestos encapsulant before the piping is cut. The intent of this procedure is reduce the amount of asbestos material that is disturbed and to reduce the potential for fiber release into the worker's breathing zone.

6.13 Decontamination, work methods and sequencing for the abatement area shall be included in the submitted work plan and approved by the Owner's Representative with the goals to minimize potential worker exposure and to minimize down time for the high pressure steam- and condensate-return lines.

7. Waste Disposal:

7.1 Workers shall double bag all asbestos contaminated debris in sealed leak-tight 6-mil plastic bags. Waste shall be removed through the waste load-out facilities separate from the personnel decontamination facility.

7.2 Contractor shall deliver the waste to an asbestos-approved Class III landfill. Contractor shall maintain a log of asbestos waste leaving the work area and shipped to the landfill. Owner’s Representative shall pre-approve shipments.

7.3 Payment of disposal charges shall be the responsibility of the Contractor. Contractor shall provide a receipt from the landfill for the waste material.

8. Post-Abatement Cleanup:

8.1 Contractor shall clean all remaining piping from which insulation has been removed to eliminate all visible traces of original insulation.

8.2 Contractor shall clean all surfaces in the workspace, using HEPA vacuums and wet methods, to eliminate all visible dust and debris.

9. Encapsulation and Lockdown:

9.1 Contractor shall encapsulate all remaining surfaces from which asbestos pipe insulation has been removed.

9.2 Contractor shall repair and encapsulate all asbestos fittings remaining on structures not to be demolished.

9.3 When the project has passed the final visual inspection, Contractor shall spray a lockdown product over all surfaces in the work area. The product must be an acrylic- or latex-based material intended for application after removal of asbestos-containing materials.
