3.6 PERSONNEL AND AREA AIR MONITORING

3.6.1 General

Monitoring and testing of airborne concentrations of asbestos fibers shall be in accordance with 29 CFR 1926.1101 and shall be performed by an approved testing laboratory and by approved Air Monitoring Personnel. All air monitoring shall be performed by the Industrial Hygienist, or their approved designee and shall include as a minimum, pre-abatement, personal, area, and post-abatement air samples as required by Federal, State, and local regulations. Analysis of the air samples shall be performed at the work site, unless otherwise approved and shall be analyzed and the results reviewed by the approved air monitoring personnel within one hour of the time the samples were taken. Monitoring results shall be signed by the person performing the air monitoring and copies of the results shall be submitted as part of the Personnel and Area Air Monitoring Logs within 3 working days after the sample was taken. The Industrial Hygienist, or their designee, shall notify the Contractor and the Government on site immediately of the results of any air sample that indicates airborne fiber concentrations in excess of the acceptable limits.

3.6.2 Pre-Abatement Air Sampling

Area air samples shall be taken for each asbestos removal site and the reference Time-Weighted Average (TWA) established prior to the start of any abatement work. The number of general air samples required to be taken to establish the reference TWA for each abatement site shall be determined by the Industrial Hygienist and submitted for approval in the abatement plan.

3.6.3 Air Monitoring During Abatement Work

Personal and area air monitoring shall be provided and the TWA and excursion exposure levels shall be established during the first exposure to airborne concentrations of asbestos. Thereafter, provided the same type of work is performed, air monitoring shall be provided at a frequency as designated by the Industrial Hygienist. If monitoring outside the asbestos control area shows airborne concentrations have reached the action level, work shall be stopped and the Government on site notified immediately. The condition(s) causing this increase shall be corrected prior to the continuance of any abatement work.

3.6.4 Post-Abatement Air Sampling

Under aggressive conditions, area air samples shall be taken to establish the clearance TWA in the asbestos control area. A maximum TWA of less than

0.01 fibers/cc shall be established after final cleanup and before removal of the containment barrier. The fiber counts from these samples shall be less than 0.01 fibers/cc or less than or equal to the reference TWA whichever is less. Should any of the final samplings indicate a higher value, appropriate actions shall be taken by the Contractor to re-clean the area and the area air sampling shall be repeated.

3.7 SITE INSPECTION

While performing asbestos removal work, the Contractor shall be subject to on-site inspection. If the work is in violation of specification

SECTION 02 82 14.00 10 Page 11 requirements or any Federal, State, or local regulations, a stop work order will be issued to be in effect immediately and until the violation is resolved. Standby time and expenses required to resolve the violation shall be at the Contractor's expense.

3.8 DISPOSAL OF ASBESTOS-CONTAINING MATERIALS

3.8.1 Friable Asbestos-Containing Materials

Adequately wetted friable ACM shall be placed in approved containers.

Caution labels shall be applied on the containers in accordance with 29 CFR 1926.1101 (k), (7) & (8), if not already preprinted on the containers. External surfaces of the filled containers shall be thoroughly cleaned by wet sponging prior to being transported out of the regulated areas. Bags shall not be overfilled and shall be securely sealed to prevent accidental opening and leakage by twisting and taping the tops of bags in a goose-neck fashion. Unless otherwise approved, bags shall be placed in drums for staging and transportation to the approved landfill.

Friable asbestos-containing waste with sharp-edged components, or which may puncture the disposal bags or plastic sheeting, shall be placed into approved disposal drums and sealed with locking ring tops.

3.8.2 Non-Friable Asbestos Containing Materials

Non-friable asbestos materials shall be removed, transported, and disposed of, in such a manner as to prevent the materials from becoming friable. If at any time the non-friable materials are handled in a manner that they become friable, then all of the requirements for the removal, transportation, and disposal of friable ACM shall be required.

3.8.3 Disposal

ACM shall be disposed of by burial at a State-permitted sanitary landfill.

ACM shall be hauled to the landfill in a closed container and all procedures for hauling and disposal shall comply with 40 CFR 61 Subpart M, 49 CFR 171, and 49 CFR 172, and State and local standards. ACM shall not be allowed to accumulate on site for more than 30 days.

3.9 WASTE SHIPMENT RECORD (WSR)

A WSR shall be completed and submitted for this contract as specified in 40 CFR 61, subpart M. Other state waste manifest shipment records shall be submitted within 10 days of delivery to the landfill and before the completion date of this contract.
