The following is the asbestos project design for abatement of applicable asbestos containing materials within designated spaces at the City of Wausau WWTP Facility. The work is regulated by WI Department of Health Services (WI DHS 159), WI Department of Natural Resources (WDNR 447) and the Occupational Safety and Health Administration (OSHA). The abatement contractor must adhere to all applicable regulations regarding abatement and disposal of asbestos materials and also follow building owner stipulations: REMOVAL OF ASBESTOS CONTAINING MATERIAL Regulated Area: Interior/Exterior Friable and Non-Friable Materials: Tank Insulation, Pipe Insulation, Fixture Heat Shield, Floor Tile, Adhesive, Caulking, Glazing. Place critical barriers over each opening to the containment area (windows, doors, heating vents, lockers, etc). Place approved danger sign posting at each access point to each containment. Where applicable, provide rigid barriers (plywood or equivalent) at each location where a poly barrier would not be sufficient to keep building occupants or public from entering the work area. Protect non-movable items within the work areas from potential damage and/or contamination during abatement process by installing poly coverings. Install a minimum one layer of wall poly and two layers (plus dropcloth) of floor poly. Provide additional protection as necessary to protect room surfaces from potential damage during removal of the ceiling system and interior building component demolition. Especially provide for protection of water migration during abatement. Provide opaque poly or other method of visual barrier where ever public or building occupant view would be possible. Install decontamination system with air lock chambers to provide proper transfer of personnel and equipment. Install temporary lighting sufficient as necessary to provide adequate lighting. Shut down and lock-out all air handling and ventilation systems to the affected area (all ventilation system equipment openings require two layers of critical barrier - minimum 6 mil poly). Disable electrical systems that would be affected by the abatement work and provide power source by ground fault protected service from outside of the work area. Negative Pressure Containment: Establish negatively pressurized work area utilizing High Efficiency Particulate Air (HEPA) filtered fan units. Show evidence of a minimum of four air changes per hour to the work area. Negative pressure should be continuously monitored to show a minimum of -0.02 inches (by recording manometer). HEPA filtered fan units should be exhausted to the exterior of the building. Exhaust openings should be designed to allow for protection of building finishes and also to provide for building security. Additional HEPA fan units may be required to account for additional containment volume of spaces located above ceilings, including the adjacent hallway ceiling. Removal of Asbestos Containing: Interior/Exterior Friable and Non-Friable Materials: Tank Insulation, Pipe Insulation, Fixture Heat Shield, Floor Tile, Adhesive, Caulking, Glazing. Abate asbestos containing material utilizing wet methods within a negative pressure enclosure. Materials must be thoroughly wetted (to the extent possible) prior to and during removal activity. Apply an approved spray encapsulant to abated surfaces following final cleaning and visual inspection. Asbestos containing pipe insulation is to be removed by wet gross technique or by glovebag procedure including sufficiently wetting the insulation to control airborne fiber release. All portions of the material are to remain wet during the removal process. Asbestos containing floor tile and adhesive is to be removed using hand methods after the material has been sufficiently wetted to control airborne fiber release. Specific hand method and associated equipment should be selected to minimize breakage of the material during abatement. Removed materials shall be packaged while wet as abatement proceeds. Waste materials should be containerized and transferred from the work area at least daily (no stock piling of waste). Following removal of all ACM, surfaces within the work area must be wet cleaned and/or cleaned by HEPA vacuum. The abatement supervisor must perform a visual inspect to detect the presence of any residual suspect material, dust or debris. Cleaning must continue until all evidence of suspect dust or debris is gone. Disposal of Asbestos Materials: Asbestos containing materials must be packaged while wet in appropriate containers. Minimum 6 mil poly disposal bags with approved asbestos labeling and waste generator information. For sharp objects such as wire mesh, metal, etc., a burlap bag or fiber/metal drum may be used in conjunction with poly bags. Hard surface items may possibly be washed and disposed of as normal construction debris. Care must be taken to thoroughly decontaminate these items. Other materials proven to be non-ACM may be disposed of as non-ACM waste. The contractor shall insure that these non-ACM wastes have no asbestos material or debris attached prior to disposal. Transfer of waste materials to dumpster or waste hauling vehicle will be coordinated with the building owner and only transferred during approved times. Transport of asbestos waste shall be in a WI DNR licensed vehicle or approved dumpster. Waste shall be disposed of in a WI DNR approved landfill. A copy of each waste manifest must be forwarded to the building owner or included in project documentation. Personal Protective Equipment: Personal protective equipment (PPE) must be worn by all persons entering the regulated area. This shall include proper respiratory protection (minimum half-face hepa filtered negative pressure respirators), disposable suits, foot covering, hand & head protection, etc. The abatement contractor is solely responsible to determine the extent of PPE necessary for the specific work area. Personal exposure air samples must be collected to determine worker exposure to airborne asbestos during each type of work activity. Results of exposure monitoring must be included in post-project submittals. Project Clearance: Following completion of abatement and final cleaning, the abatement contractor supervisor must perform a visual inspection to determine the thoroughness of cleaning. Any suspect dust or debris must be cleaned prior to encapsulation. All containment poly (excluding critical barriers) will be removed following encapsulation. Post barrier cleaning shall be performed prior to air testing. Prior to air clearance testing, the third party air monitoring technician (NorthStar Environmental) will perform a visual inspection. Any residual asbestos material or any suspect dust, debris or questionable material noted during the visual inspection will require removal or cleaning. The building owner will pay for initial air clearance. Follow up clearance required following air clearance failure for reasons related to airborne asbestos within the containment will be paid for by the abatement contractor. Clearance protocol for asbestos air sampling will be by phase contrast microscopy (PCM), NIOSH 7400A Method. Project Closeout and Documentation: At the completion of the project, the abatement contractor must submit the following records prior to request for payment: - WDNR required project notification. - WI DHS required project log, occupant protection plan, project notification. - OSHA air monitoring results. - Project activity logs or notes. - WI DHS certification/licensing for abatement personnel. - Medical surveillance and respirator fit-test records. - Waste disposal manifests.
