PART 1 - GENERAL

1.1 SUMMARY

A. Section includes requirements for Contractor to prepare an asbestos containing material (ACM) removal and disposal plan. After review and approval of the Plan, Contractor is required to per-form removal of asbestos and dispose of legally.

B. Description of Work: The work covered by this section includes the handling and control of as-bestos containing materials and describes some of the resultant procedures and equipment re-quired to protect workers and the environment from contact with airborne asbestos fibers. The work also includes the disposal of asbestos containing materials generated by the work.

Contractor shall observe all existing conditions prior to submitting a bid. The Contractor shall have considered, and included in their bid, all aspects of the existing conditions and their impact, particularly to cost and health and safety of workers and occupants. Failure to visit the site shall not provide relief from performing any work that may be required to complete the work in accordance with the Contract Documents without additional cost. All site visits required by the Contractor shall be scheduled with NJARNG.

Material information and quantities are documented from the following surveys: Asbestos Survey Building Demolition Superstorm Sandy Projects Report by NJDMAVA dated 25 September 2014, and Asbestos Environmental Inspection Activities Report at Sea Girt by Whitman dated December 2012, and is available as supplemental information. The quantities, locations and the extent of work indicated (within the Survey Reports) are the known quantities.

Contractor shall be responsible for abatement of all elements including third party air monitoring and containment clearance. Variations (plus or minus 10 percent) in quantities within the limits of containment for the work area (as defined within the Report) are considered as having no impact on contract sum and contract performance period. Locations of materials different than indicated within the Report but within the limits of containment are considered as having no impact on contract sum and contract performance period.

REMOVAL AND DISPOSAL OF ASBESTOS CONTAINING MATERIAL 02 82 33 - 9

A. Perform asbestos related work in accordance with 29 CFR 1926.1101, 40 CFR 61-SUBPART M, and as specified herein. Use wet removal procedures. Personnel shall wear and utilize pro-tective clothing and equipment as specified herein. Eating, smoking, drinking, chewing gum, tobacco, or applying cosmetics shall not be permitted in the asbestos work or control areas.

Personnel of other trades not engaged in the removal and demolition of asbestos containing ma-terial shall not be exposed at any time to airborne concentrations of asbestos unless all the per-sonnel protection and training provisions of this specification are complied with by the trade personnel. Shut down the building heating, ventilating, and air conditioning system, cap the openings to the system, prior to the commencement of asbestos work. Disconnect electrical service when wet removal is performed and provide temporary electrical service with verifiable ground fault circuit interrupter (GFCI) protection prior to the use of any water. If an asbestos fiber release or spill occurs outside of the asbestos control area, stop work immediately, correct the condition to the satisfaction of the Contracting Officer including clearance sampling, prior to resumption of work.

3.3 ASBESTOS CONTROL AREA REQUIREMENTS

A. The construction of a negative pressure enclosure is infeasible for the removal of ACM in the building which is not occupied and will be completely demolished. Use alternate techniques as indicated in 29 CFR 1926.1101. Establish designated limits for the asbestos regulated area with the use of rope or other continuous barriers, and maintain all other requirements for asbestos control areas. The PQP shall conduct personal samples of each worker engaged in asbestos handling (removal, disposal, transport and other associated work) throughout the duration of the project. If the quantity of airborne asbestos fibers monitored at the breathing zone of the work-ers at any time exceeds background or 0.01 fibers per cubic centimeter whichever is greater, stop work, evacuate personnel in adjacent areas or provide personnel with approved protective equipment at the discretion of the Contracting Officer. This sampling may be duplicated by the Government at the discretion of the Contracting Officer. If the air sampling results obtained by the Government differ from those obtained by the Contractor, the Government will determine which results predominate. If adjacent areas are contaminated as determined by the Contracting Officer, clean the contaminated areas, monitor, and visually inspect the area as specified herein.

3.4 REMOVAL PROCEDURES

A. Wet asbestos material with a fine spray of amended water or a specific wetting agent such as light oil during removal, cutting, or other handling so as to reduce the emission of airborne fi-bers. Remove material and immediately place in 6 mil plastic disposal bags. Remove asbestos containing material in a gradual manner, with continuous application of the amended water or wetting agent in such a manner that no asbestos material is disturbed prior to being adequately wetted. Where unusual circumstances prohibit the use of 6 mil plastic bags, submit an alternate proposal for containment of asbestos fibers to the Contracting Officer for approval. For exam-ple, in the case where both piping and insulation are to be removed, the Contractor may elect to wet the insulation, wrap the pipes and insulation in plastic and remove the pipe by sections.

Asbestos containing material shall be containerized while wet. At no time shall asbestos mate-rial be allowed to accumulate or become dry. Lower and otherwise handle asbestos containing material as indicated in 40 CFR 61-SUBPART M.

REMOVAL AND DISPOSAL OF ASBESTOS CONTAINING MATERIAL 02 82 33 - 10

B. Sealing Contaminated Items Designated for Disposal: Remove contaminated architectural, me-chanical, and electrical appurtenances such as venetian blinds, full-height partitions, carpeting, duct work, pipes and fittings, radiators, light fixtures, conduit, panels, and other contaminated items designated for removal by completely coating the items with an asbestos lock-down en-capsulant at the demolition site before removing the items from the asbestos control area. These items need not be vacuumed. The asbestos lock-down encapsulant shall be tinted a contrasting color. It shall be spray-applied by airless method. Thoroughness of sealing operation shall be visually gauged by the extent of colored coating on exposed surfaces. Lock-down encapsulants shall comply with the performance requirements specified herein.

C. Exposed Pipe Insulation Edges: Contain edges of asbestos insulation to remain that are exposed by a removal operation. Wet and cut the rough ends true and square with sharp tools and then encapsulate the edges with a 1/4 inch thick layer of non-asbestos containing insulating cement troweled to a smooth hard finish. When cement is dry, lag the end with a layer of non-asbestos lagging cloth, overlapping the existing ends by at least 4 inches. When insulating cement and cloth is an impractical method of sealing a raw edge of asbestos, take appropriate steps to seal the raw edges as approved by the Contracting Officer.

3.5 AIR SAMPLING

A. Air sampling will be performed by NJARNG.

B. Should any of the final samples indicate an unacceptable value, the Contractor shall take appro-priate actions to re-clean the area at the Contractor's expense.

3.6 CLEAN-UP AND DISPOSAL

A. Housekeeping: Essential parts of asbestos dust control are housekeeping and clean-up proce-dures. Maintain surfaces of the asbestos control area free of accumulations of asbestos fibers.

Give meticulous attention to restricting the spread of dust and debris; keep waste from being distributed over the general area. Use HEPA filtered vacuum cleaners. DO NOT BLOW DOWN THE SPACE WITH COMPRESSED AIR. When asbestos removal is complete, all as-bestos waste is removed from the work-site, and final clean-up is completed, the Contracting Officer will attest that the area is safe before the signs can be removed. The Contracting Officer will visually inspect all surfaces within the enclosure for residual material or accumulated dust or debris. The Contracting Officer must agree that the area is safe in writing before unrestricted entry will be permitted. The Government shall have the option to perform monitoring to deter-mine if the areas are safe before entry is permitted.

B. Title to Materials: All waste materials, except as specified otherwise, shall become the property of the Contractor and shall be disposed of as specified in applicable local, State, and Federal regulations and herein.

3.7 DISPOSAL OF ASBESTOS

A. Procedure for Disposal: Collect asbestos waste, asbestos contaminated water, scrap, debris, bags, containers, equipment, and asbestos contaminated clothing which may produce airborne

REMOVAL AND DISPOSAL OF ASBESTOS CONTAINING MATERIAL 02 82 33 - 11

concentrations of asbestos fibers and place in sealed fiber-proof, waterproof, non-returnable containers (e.g. double plastic bags 6 mils thick, cartons, drums or cans). Wastes within the containers must be adequately wet in accordance with 40 CFR 61-SUBPART M. Affix a warn-ing and Department of Transportation (DOT) label to each container including the bags or use at least 6 mils thick bags with the approved warnings and DOT labeling preprinted on the bag.

The name of the waste generator and the location at which the waste was generated shall be clearly indicated on the outside of each container. Prevent contamination of the transport vehi-cle (especially if the transport vehicle is a rented truck likely to be used in the future for non-asbestos purposes). These precautions include lining the vehicle cargo area with plastic sheet-ing (similar to work area enclosure) and thorough cleaning of the cargo area after transport and unloading of asbestos debris is complete. Dispose of waste asbestos material at an Environmen-tal Protection Agency (EPA) or State-approved asbestos landfill off Government property. For temporary storage, store sealed impermeable bags in asbestos waste drums or skids. An area for interim storage of asbestos waste-containing drums or skids will be assigned by the Contracting Officer or his authorized representative. Procedure for hauling and disposal shall comply with 40 CFR 61-SUBPART M, State, regional, and local standards. Sealed plastic bags may be dumped from drums into the burial site unless the bags have been broken or damaged. Dam-aged bags shall remain in the drum and the entire contaminated drum shall be buried. Uncon-taminated drums may be recycled. Workers unloading the sealed drums shall wear appropriate respirators and personal protective equipment when handling asbestos materials at the disposal site.

B. Asbestos Disposal Quantity Report: Record and report, to the Contracting Officer, the amount of asbestos containing material removed and released for disposal. Deliver the report for the previous day at the beginning of each day shift with amounts of material removed during the previous day reported in linear meters or square meters linear feet or square feet as described in-itially in this specification and in cubic meters feet for the amount of asbestos containing mate-rial released for disposal.
