OSHA Class I abatement area decontamination enclosures will include the following features: An equipment or dirty room with two doorways, one to the work area and one to the shower room. Facilities Services Department Page 5 of 9

6 A shower room with two doorways, one to the equipment room and one to the airlock/clean room. The shower room shall contain at least one shower with hot and cold water. Careful attention shall be paid to the shower enclosure to ensure against any leaking. Soap and shampoo will be available in the shower room at all times. Clean and dry towels will be available for employees and any Owner authorized visitors and personnel. A three-stage water filtration system will be employed prior to release of shower water into the local sewage system. An airlock/clean room with one doorway into the shower room and one to the outside area. OSHA Class II abatement area decontamination enclosures will include the following features: An equipment or dirty room with two doorways, one to the work area and one to the clean room. A clean room with one doorway into the dirty room and one to the outside area. Wash water, clean and dry towels will be available in this room for employees and any Owner authorized visitors and personnel. A three-stage water filtration system will be employed prior to release of water into the local sewage system. Waste load-out shall take place through a two-stage waste load-out enclosure system constructed prior to waste load-out at the end of the abatement project or at the end of daily work. No gross abatement shall be performed while load-out is taking place. If the Contractor requests to use the worker decontamination facility for waste load-out, approval will be based on a no impact judgment on the protection to facilities or the final project provided to the Owner. Bags of ACM will be wet wiped, removing all visible material from the exterior of the bags outside of the dirty room. Each bag will then be passed into the dirty room where it will be bagged again with a bag from the shower room. Load-out of the bag can then take place, after the bag is inspected to insure no contamination has taken place. Evacuation of excess air by HEPA vacuum is recommended. The waste transfer unit shall be fully lined (except ceiling) with one layer of 6-mil poly. The Contractor shall test the unit leak-tight and lockable. 3.3 ASBESTOS REMOVAL WORK SHALL NOT COMMENCE UNTIL: Arrangements have been made for disposal of waste at an EPA approved dumpsite. Arrangements have been made for containing and/or disposal of wastewater resulting from showering and other abatement activities.

7 The Type C supplied air respirator systems are on-site and fully operative or can be set up within 24 hours of notice by the Owner's representative that Type C respiratory system is required. All other preparatory steps have been taken and applicable notices posted, and permits are obtained. A visitor and employee log-in log-out system is in place at the job site. All persons entering the site will be required to sign in and sign out. Sufficient differential pressure is established inside containment per Technical Specifications. A formal pre-abatement safety and procedure meeting has been held at the site with Owner's and Contractor's employees present. At this time the Contractor's final abatement plan must be submitted for each abatement area. 3.4 MAINTENANCE OF ENCLOSURE SYSTEMS Ensure that barriers and plastic linings are effectively sealed and taped. Repair damaged barriers and remedy defects immediately upon discovery. Visually inspect enclosures and differential pressure units at the beginning of each work period or shift. Details of the inspections are to be included in the Contractor s daily log. Use smoke methods to test effectiveness of barriers and the differential pressure containment system when directed by the Owner. 3.5 CONTAINMENT CLEARANCE Removal and detail cleaning work will be considered complete when all surfaces inside containment areas have no visible debris or asbestos residue and have passed final clearance visual inspection by the Owner's Representative. Aggressive air samples will be taken for clearance after a visual inspection has been passed. The Contractor will be allowed two visual inspections, and if work is still required after two inspections the Contractor shall pay for any costs associated with the additional inspections. The inner poly wall and floor shall be removed after the visual inspection is approved. Any contamination that penetrated the inner poly layer shall be thoroughly decontaminated and cleaned. If the outer poly layer was punctured or material leaked through, then the outer poly shall be removed in the contaminated areas and all contaminated materials cleaned or removed as contaminated materials. PCM air clearance testing will be performed by the Owner's Representative collecting a containment size appropriate number of samples inside the work area each with an air volume of 1200 to 1800 liters taken at 10 liters per minute or less. The samples will be analyzed by Phase Contrast Microscopy NIOSH Method PCM clearance samples must be at Nevada asbestos regulation levels of 0.01 fibers per cubic centimeter (cc) or less to achieve Air Clearance. If clearance samples fail the Contractor is responsible for all subsequent consulting Facilities Services Department Page 7 of 9

The Contractor shall remedy the situation that caused the failure, i.e., filter outside dirty air, re-clean inside surfaces or other, and then the Owner's Representative shall retest the containment area. Once the Visual Inspection and PCM Air Clearance is achieved encapsulation can occur. After encapsulation dries and passes inspection the Contractor shall remove all barriers and equipment. 3.6 DISPOSAL As the work progresses, and to prevent exceeding available dumpster storage capacity on site, remove asbestos waste and dispose of at an EPA approved disposal site in accordance with the requirements of the disposal authority.
