Notification of the Authority: If the critical or primary barrier falls or is breached in any manner, stop work immediately and notify the Authority. Do not begin work until authorized in writing by the Authority. 3.3 ENTRY AND EXIT PROCEDURES A. Authorized personnel shall enter the work area through the worker decontamination facility system. ASBESTOS ABATEMENT

22 B. Upon entry and exit to work area, all personnel shall sign a log located outside the worker decontamination facility. C. Post decontamination and work procedures outside of the worker decontamination facility. These procedures shall be discussed with the workers at the beginning of the project. D. Workers shall enter the project through the worker decontamination facility, don PPE and go to the work area within those areas regulated with boundary tape. Upon completion of the work, they shall return to the worker decontamination facility through the demarked area, and properly decontaminate themselves. At no time shall they go beyond the demarked areas, either going to or leaving the work area without first either entering or leaving the decontamination facility. Others shall not be permitted to enter the demarked area at any location at any time during the work. E. Personnel Protection: Personal protection procedures shall follow the approved Asbestos Hazard Abatement Plan, approved Respiratory Protection Program, the Fall Protection Plan, and as specified herein. 1. All personnel entering the work area for the first time shall sign a statement that they have read and understand all posted regulations, are familiar with personal protection requirements, and emergency procedures. 2. Personnel shall be fully protected with respirators and protective clothing before the first disturbance of contaminated materials, and until final clean-up is completed. Respirator face pieces shall not be removed in the work area. 3. Persons wearing beards shall not be allowed to enter the work area. 4. Eating, drinking, applying cosmetics, smoking, and chewing gum or tobacco will not be allowed in the work area. F. Holding Room Entry and Exit: 1.

23 3.4 AIR MONITORING A. The Authority: The Authority will retain the services of an industrial hygiene firm (known as third party IH firm) to perform perimeter and area air monitoring and clearance sampling as directed by the Authority. The third party IH will: 1. Monitor the airborne concentration of asbestos before starting work to obtain a baseline fiber concentration in the affected areas. 2. Monitor air to measure the asbestos fiber levels within work area and each decontamination facility system throughout removal, disposal, and clean-up. 3. The number and location of the air sample collected by the third party IH will be determined in consultation with the Authority. B. By the Contractor: 1. Collection of personal air samples shall be the responsibility of the Contractor. Personal samples shall be collected by the CP or other designated individual in accordance with 29 CFR Contractor is to submit qualifications of individuals and laboratories performing the sampling and sample analysis respectively. The results shall be reviewed by the Contractor s CIH and transmitted to the Authority under his/her signature. 2. At no time shall air concentrations of asbestos fibers exceed of 0.01 f/cc of air outside of the work area. If sampling outside the work area shows airborne levels have exceeded 0.01 f/cc, stop all work, correct the condition (s) causing the increase, and notify the Authority immediately. If an asbestos fiber release occurs outside of the asbestos control area, stop work immediately, correct the condition to the satisfaction of the Authority, including clearance sampling, prior to resumption of work. In both cases, the Contractor s CIH shall provide the response in writing as well as the corrective actions. The CIH shall also sign this document. 3.5 ASBESTOS-CONTAINING ROOFING MATERIAL REMOVAL PROCEDURES A. Roofing materials shall not be sanded, abraded, or ground, and must be removed using manual methods so that the material remains intact. The personnel impacting roofing materials must be knowledgeable of the revised paragraph (g)(8)(ii) of the OSHA Standard 29 CFR and comply with all aspects of the Standard. B. Prior to the start of the job, the roof must be examined by a competent person to ASBESTOS ABATEMENT

24 determine whether the roofing material is intact and is likely to remain intact throughout the job. C. Personnel impacting the roofing materials must be trained in the hazards of asbestos exposure, and proper work practices and prohibitions applicable to such work. If these conditions are not met, then the job must be treated as a Class II OSHA removal. D. The following procedures are to be used: 1. Demarcate work area using barrier tape. 2. Approved warning signs shall be posted at appropriate entrances to active work. 3. A worker decontamination facility shall be installed in close proximity to the active work area. Barrier tape to demark the ingress/egress route from the active work area to the decontamination facility shall be erected. 4. The ACM shall be sprayed with a penetrating mist prior to the actual removal process. The penetrating mist (amended water) is an aqueous solution of polyoxyethylene esters of mixed organic acids (47%) and polyoxyethylene ether of alkylated phenols (47%) and a silicone defoaming agent. The wetting agent shall be mixed in proportions consistent with the manufacturer's instructions. 5. Manual hand tools shall be used to the fullest extent possible to remove the roofing materials and therefore minimize the potential for the material to become friable. 6. The parts of the roofing system to remain, if any, shall be protected. 7. Roofing material shall be removed in an intact state to the extent feasible. 8. Wet methods shall be used to remove roofing materials that are not intact, or that will be rendered not intact during removal, unless such wet methods are not feasible or will create safety hazards as defined by the CP. 9. When removing built-up roofs with asbestos-containing roofing felts and an aggregate surface using a power roof cutter, all dust resulting from the cutting operation shall be collected by a HEPA dust collector, or shall be HEPA vacuumed by vacuuming along the cut line. When removing built-up roofs with asbestos-containing roofing felts and a smooth surface using a power roof cutter, the dust resulting from the cutting operation shall be collected either by a HEPA dust collector or HEPA vacuuming along the cut line, or by gently sweeping and ASBESTOS ABATEMENT

25 then carefully and completely wiping up the still wet dust and debris left along the cut line. 10. Because the project is located adjacent to active taxiways, all debris, waste and ACM that has been removed from the roof shall be wrapped and contained at all times at the location of its removal. After wrapping or otherwise containing, it shall be lowered to the ground via crane or hoist; the use of a chute is not permitted. 11. Any ACM that is not intact shall be lowered to the ground as soon as is practicable, but no later than the end of the work shift. While the material remains on the roof it shall either be kept wet, placed in an impermeable waste bag, or wrapped in plastic sheeting. 12. Intact ACM shall be lowered to the ground as soon as is practical, but no later than the end of the work shift. 13. Upon being lowered, unwrapped material shall be transferred to a closed receptacle in such a manner as to preclude the dispersion of dust. 14. Roof level heating and ventilation air intake sources shall be isolated, or the ventilation system shut down. 15. Notwithstanding any other provision of this section, removal or repair of sections of intact roofing less than 25 square feet in area does not require use of wet methods or HEPA vacuuming as long as manual methods, which do not render the material non-intact, are used to remove the material, and no visible dust is created by the removal method used. In determining whether a job involves less than 25 square feet, the Contractor shall include all removal and repair work performed on the same roof on the same day. 3.6 SITE INSPECTION/CLEARANCE A. While performing asbestos engineering control work, the Contractor shall be subject to on-site inspections by OSHA and EPA inspectors, local building/health officials, the Authority, and Authority s third party IH. If the work is found to be in violation of this specification by one of these officials, the Contractor shall stop work immediately. The Authority will issue a stop work order to be in effect immediately and until the violation is resolved. All related costs, including standby time required to resolve the violation, shall be at the Contractor s expense. B. Prior to removal of plastic barriers and barrier tape, and after pre-clearance clean up of gross contamination, the Authority and/or Authority s industrial hygienist, will ASBESTOS ABATEMENT

26 conduct a visual inspection of all areas affected by the removal in accordance with ASTM E CLEARANCE PROCEDURES A. The Contractor shall ensure that complete removal of ACM from the substrate has been accomplished. B. Collect the ACM waste and transport it out of the work area enclosure according to appropriate asbestos waste handling procedures. C. Wet clean and HEPA vacuum all surfaces within the work area to eliminate all visible residue using EPA approved methods. Do not allow contaminated water to excessively accumulate inside the regulated areas. D. The Authority will conduct a visual inspection of the work area enclosure for any remaining visible debris and residue, and re-clean if necessary. E. Before moving contaminated equipment and polyethylene to the decontamination facility system, clean external surfaces (i.e. scaffolding, ladders, etc.) thoroughly by wet cleaning and HEPA vacuuming. F. Collect used water, and filter with approved water filtration equipment to remove asbestos contamination. Dispose of filters and residue as asbestos waste. Discharge clean water to the sanitary system. Dispose of asbestos contaminated work clothing as asbestos contaminated waste. G. When air monitoring tests and/or the Authority s third party IH perform a satisfactory visual clearance, remove worker decontamination facility, thoroughly wet-clean and HEPA vacuum work area, and dispose of contaminated waste. Inspect to ensure that no asbestos remains on surfaces as a result of dismantling. H. Remove seals from openings. 3.8 DISPOSAL A. Secure necessary permits in conjunction with asbestos disposal and hauling. Provide timely notification of such actions, as may be required by federal, state, regional, and local authorities. Notify the regional office of the EPA and provide copies of the notification to the Authority ten (10) days prior to the commencement of the work in accordance with 40 CFR 61. B. Procedure for disposal and hauling of asbestos waste shall comply with approved Hazard Waste Management Plan and 40 CFR 61 Subpart M. Dispose and transport ASBESTOS ABATEMENT
