ASBESTOS CONTAINING MATERIAL (ACM) REMOVAL AND DISPOSAL

PART 1 GENERAL

1.1 SCOPE

ACM is confirmed to be present in the felt plies, flashings and coating materials used on portions of the existing built-up roofing (BUR) system at some of the pumping stations. See the Bulk Asbestos Fiber Analysis Report attached at the end of this specification section for the locations, type, and concentration level of asbestos fibers found and components of the roofing system assembly they are present in. Asbestos fibers are anticipated to be encapsulated and pliable in the asphalt bitumens used to adhere the plies and the top coatings used at certain roofs. Thus, for OSHA Class II ACM determined to be intact by the Industrial Hygienist (IH), the Contractor will be allowed to use the alternative methods for compliance pursuant to meeting all of the conditions required by 29 CFR 1926.1101 (g)(11), Alternative methods of compliance for installation, removal, repair, and maintenance of certain roofing and pipeline coating material. Use of alternate methods for compliance shall also be subject to meeting the additional requirements for ACM removal and disposal as specified herein. For Class II ACM that is not intact or that may become non-intact as determined by the IH, the Contractor shall follow the broader requirements of 29 CFR 1926.1101 .

Suspect friable ACM shall require the Contractor to stop work and notify the COR.

When such confirmation is conducted, it shall be from the same sample filter used for the NIOSH 94-113 Method 7400 PCM analysis. All confirmation of asbestos fiber concentrations, using NIOSH 94-113 Method 7402, shall be at the Contractor's expense.

3.1.2 Initial Exposure Assessment

The Contractor shall conduct an exposure assessment immediately before or at the initiation of an operation to ascertain expected exposures during that operation. The assessment shall be completed in time to comply with the requirements, which are triggered by exposure data or the lack of a negative exposure assessment, and to provide information necessary to assure that all control systems planned are appropriate for that operation. The assessment shall take into consideration monitoring results and all observations, information or calculations which indicate employee exposure to asbestos, including any previous monitoring conducted in the workplace, or of the operations of the Contractor which indicate the levels of airborne asbestos likely to be encountered on the job.

3.1.3 Negative Exposure Assessment

Provide a negative exposure assessment for all asbestos jobs prior to initiation of work or within the first 2 days of work and conform to the following criteria:

a. Objective Data: Objective data demonstrating that the product or material containing asbestos minerals or the activity involving such product or material cannot release airborne fibers in concentrations exceeding the PEL-TWA and PEL-Excursion Limit under those work conditions having the greatest potential for releasing asbestos.

b. Prior Asbestos Jobs: Where the Contractor has monitored prior asbestos jobs for the PEL and the PEL-Excursion Limit within 12 months of the current job, the monitoring and analysis were performed in compliance with asbestos standard in effect; the data were obtained during work operations conducted under workplace conditions closely resembling the processes, type of material, control methods, work practices, and environmental conditions used and prevailing in the Contractor's current operations; the operations were conducted by employees whose training and experience are no more extensive than that of employees performing the current job; and these data show that under the conditions prevailing and which will prevail in the current workplace, there is a high degree of certainty that the monitoring covered exposure from employee exposures will not exceed the PEL-TWA and PEL-Excursion Limit.

c. Initial Exposure Monitoring: The results of initial exposure monitoring of the current job, made from breathing zone air samples that are representative of the 8-hour PEL-TWA and 30-minute short-term

SECTION 02 82 14.00 28 - Page 15 exposures of each employee. The monitoring covered exposure from operations which are most likely during the performance of the entire asbestos job to result in exposures over the PELs.

3.1.4 3.8.4 Environmental Air Monitoring During Abatement

Until an exposure assessment is provided to the COR, environmental air monitoring shall be conducted at locations and frequencies that will accurately characterize any evolving airborne asbestos fiber concentrations. The assessment shall demonstrate that the product or material containing asbestos minerals, or the abatement involving such product or material, cannot release airborne asbestos fibers in concentrations equal to or exceeding 0.01 f/cc as a TWA under those work conditions having the greatest potential for releasing asbestos. The monitoring shall be at least once per shift at representative locations outside of the perimeter of a regulated area. If the sampling outside regulated area shows airborne fiber levels have exceeded background or equal to 0.01 f/cc, whichever is greater, work shall be stopped immediately, and the COR notified. The condition causing the increase shall be corrected. Work shall not restart until authorized by the COR.

3.1.5 Air-Monitoring Results and Documentation

Air sample fiber counting shall be completed and results provided within 24 hours for breathing zone samples. The COR shall be notified immediately of any airborne levels of asbestos fibers in excess of established requirements. Written sampling results shall be provided within 5 working days of the date of collection. The written results shall be signed by testing laboratory analyst, testing laboratory principal and the Contractor. The air sampling results shall be documented on a Contractor's daily air monitoring log. The daily air monitoring log shall contain the following information for each sample:

a. Sampling and analytical method used.

b. Date sample collected.

c. Sample number.

d. Sample type: BZ = Breathing Zone (Personal), P = Preabatement, E = Environmental, C = Abatement Clearance.

e. Location/activity/name where sample collected.

f. Sampling pump manufacturer, model and serial number, beginning flow rate, end flow rate, average flow rate (L/min).

g. Calibration date, time, method, location, name of calibrator, signature.

h. Sample period (start time, stop time, elapsed time (minutes).

i. Total air volume sampled (liters).

j. Sample results (f/cc and S/mm square) if EPA methods are required for final clearance.

k. Laboratory name, location, analytical method, analyst, confidence level. In addition, the printed name and a signature and date block

SECTION 02 82 14.00 28 - Page 16 for the Industrial Hygienist who conducted the sampling and for the Industrial Hygienist who reviewed the daily air monitoring log verifying the accuracy of the information.

3.2 REMOVAL AND DISPOSAL OF ROOFING MATERIALS

3.2.1 General

When removing roofing materials which contain ACM as described in 29 CFR 1926.1101 (g)(8)(ii), use the following practices: Roofing material shall be removed in an intact state. 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. Wet methods shall only be used at the approval of the COR.

3.2.2 Specific Removal and Disposal Requirements

The Contractor shall use the following procedures for removal and disposal of roofing materials containing asbestos:

a. The onsite ACM removal supervisor shall assess that the roofing material is in-tact prior to removal work.

b. The felt plies and flashing shall be removed by hand-held spudding tools or shovels. The use of power tools to cut, drill, grind or abrade ACM will not be allowed unless the tools are equipped with HEPA filtered dust and particulate capture and collection systems as specified above. At the approval of the COR, wet methods may 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.

c. All demolished ACM material shall be double "burrito" wrapped in 6-mil plastic sheeting while still on the roof. Stockpiles of unwrapped ACM will not be allowed to remain on the roof any longer than 4 hours of one work shift and no burrito wraps shall be left on any roof surface overnight. Burrito wraps shall be tightly bound with duct tape such that they are sealed tight with no leakage of material. Warning labels conforming to CFR 29, Part 1926 shall be affixed to all burrito wraps. Burrito wraps shall not be dropped or thrown to the ground, but shall be lowered to the ground via crane, hoist or other method approved by the Contracting Officer Representative. Roll off containers and NOT dump trucks should be used for the burrito wraps and transport vehicle to the landfill. Any waste that contains nonfriable asbestos material must be handled and disposed of using methods that will prevent the release of airborne asbestos-containing material.

d. Wrapped ACM roofing material shall be segregated from other waste material for transportation to the accepting landfill. For the purpose of developing an ACM profile, the Contractor shall also provide copies of the test results from the ACM analysis to the landfill operator. The roofing Contractor must send a Representative with the load for disposal. In the case of the burrito wrap coming apart or needing repairs before dumping, the Contractor Representative will be responsible for making all re-taping or repairs to the wrapping before the load will be dumped.

SECTION 02 82 14.00 28 - Page 17

3.3 PROTECTION OF ADJACENT WORK OR AREAS TO REMAIN

Perform asbestos abatement without damage to or contamination of adjacent work or area. Where such work or area is damaged or contaminated, it shall be restored to its original condition or decontaminated at no expense to the Government. When spills occur, work shall stop in all effected areas immediately and the spill shall be cleaned. When satisfactory visual inspection and air sampling analysis results are obtained and have been evaluated by the Contractor and the COR, work shall proceed.

3.4 PUMPING STATION VENTILATION SYSTEM AND CRITICAL BARRIERS

Pumping Station ventilation system ventilators and louvers in a regulated area shall be isolated by airtight seals to prevent the spread of contamination throughout the system. The airtight seals shall consist of air-tight rigid covers for pumping station ventilation supply and exhaust grills where the ventilation system is required to remain in service during abatement or 2 layers of polyethylene as appropriate. Edges to wall, ceiling and floor surfaces shall be sealed with industrial grade duct tape.

3.5 FINAL CLEANUP AND CLEARANCE CERTIFICATION

After completion of all asbestos removal work, the Contractor and the COR shall conduct a final visual inspection of the regulated area to ensure they are clean in accordance with ASTM E1368 and document the results. If the COR rejects the clean regulated area as not meeting final cleaning requirements, reclean as necessary and have a follow-on inspection conducted with the COR. Recleaning and follow-up reinspection shall be at the Contractor's expense. Upon government acceptance of final cleaning, the COR will allow the warning signs and boundary warning tape to be removed.

3.6 TITLE TO MATERIALS

ACM material resulting from abatement work, except as specified otherwise, shall become the property of the Contractor and shall be disposed of as specified and in accordance with applicable federal, state and local regulations. The Government will remain the documented owner of the ACM.

3.7 ASBESTOS WASTE SHIPMENT RECORDS

Complete and provide the COR final completed copies of the Waste Shipment Record for all shipments of waste material as specified in 40 CFR 61 , Subpart M and other required state waste manifest shipment records, within 3 days of delivery to the landfill. Include a description of the disposal process and provisions for the Project ECC to sign the ACM record, the non-hazardous waste manifests, or waste related bills of lading for all regulated waste being shipped off of project. Each Waste Shipment Record shall be signed and dated by the Project ECC, the waste transporter, and the disposal facility operator.

3.8 SITE INSPECTION

While performing asbestos removal work, the Contractor shall be subject to on-site inspection. If the work is in violation of specification requirements or any Federal, State, or local regulations, work shall stop

SECTION 02 82 14.00 28 - Page 18 g4edddca Line immediately and remain stopped until the violation is resolved. Standby time and expenses required to resolve the violation shall be at the Contractor's expense.
