The Owner shall retain the services of a third party project monitor to provide monitoring of asbestos removal work practices and performance, inspection of the Work, bulk fiber identification, personal, perimeter, and clearance air sampling and analysis, and visual clearance inspections throughout the asbestos abatement work. The third party project monitor shall be on Site periodically during all asbestos abatement related activities. 129 PLEASANT STREET PFRA+LDa Northampton, MA August 24, 2016 ASBESTOS REMEDIATION 028200 - 17 B. Air Monitoring 1. The air clearance acceptance criteria for this project is 0.010 fibers/cubic centimeter by PCM. PCM sample analysis shall be available within 24 hours. 2. Background (pre-testing) air samples may be taken to represent conditions before the Contractor starts masking and sealing operations. 3. During removal, daily area samples may be collected by the Owner’s third party project monitor outside major openings in the containment, in the clean room, at other critical points outside the Work areas, just outside the clean room, inside the contained Work sites, and at HEPA exhaust locations. The Contractor shall be responsible for all OSHA personal sampling. Final clearance air samples shall be collected by the Owner’s third party project monitor inside each removal area after acceptance of visual inspection and encapsulation. NOTE: Encapsulation on all surfaces (including floor) must be dry prior to final air sampling. 4. A sufficient number of samples to reliably characterize the air quality shall be collected. Air shall be agitated by means of a small leaf blower prior to the test, and kept agitated by means of a small electric fan. The results of all samples must comply with the requirements set forth in this Section. Failure to meet the specified criteria will require the Contractor to re-clean the designated work area and then the project monitor to repeat the final air clearance testing at no additional cost to the Owner. All repeat air testing shall be the Contractor's financial responsibility. Cleaning and testing will be repeated until the specified criteria are met, at no additional cost to Owner or General Contractor and the Contractor shall be responsible for any Owner’s third party project monitor fees associated with the retesting. C. Work Review 1. The Engineer and Owner’s third party project monitor will review the Contractor's work practices prior to the start of, and during all asbestos related work, and will report any violations to the Contractor. If the Contractor fails to correct deficiencies in a timely manner, the Engineer will notify the General Contractor and Work may be stopped. 2. The Owner’s third party project monitor will review the containment structure and negative air conditions before Work begins and after the Contractor Site Supervisor has given approval. 3. Outside containment and exterior regulated work areas airborne fiber concentrations must not exceed 0.010 fibers/cc or pre-abatement levels, whichever is greater. 4. If concentrations exceed this level, then Work must be stopped, conditions reviewed as to the probable cause, and then corrected by the Contractor at no additional cost to the Owner. The Owner’s third party project monitor shall keep a daily log of the Contractor's work practices and shall make these daily logs a part of the final project documents. 3.7 PERSONAL PROTECTION A. Respirators and Protective Clothing 1. Protective Clothing a.

The Contractor will maintain on Site a sufficient supply of disposable HEPA-filtered cartridges to allow workers and supervisory personnel to change contaminated cartridges at least three times daily. The Contractor is solely responsible for means and methods used and for compliance with applicable regulations. d. Respirators shall be individually assigned to removal workers for their exclusive use. e. All respiratory protection shall be provided to workers in accordance with the written submitted respiratory protection program, which includes all items in OSHA 29 CFR 1910.134 (b) (1-11). A copy of this program shall be kept at the on Site and shall be posted in the Clean Room of the Decontamination Unit. f. Workers must perform negative and positive pressure fit tests each a time a respirator is put on, whenever the respirator design permits. g. Workers shall be given a qualitative fit test in accordance with procedures detailed in the OSHA 29 CFR 1910.1025, Appendix D, Qualitative Fit Test Protocols, for all respirators to be used on this project. An appropriately administered quantitative fit test may be substituted for the qualitative fit test. h. Upon leaving the active work area, the pre-filter shall be discarded, cartridges removed, and respirators cleaned in disinfectant solution and clean water rinse. Clean respirators shall be stored in plastic bags when not in use. The Contractor shall inspect respirators daily for broken, missing, or damaged parts. 3. Personal Sampling a. The Contractor shall provide daily personal sampling to check personal asbestos exposure levels for the purpose of establishing respiratory protection needs. b. Samples shall be taken for the duration of the work shift or for eight hours, whichever is less. c. Personal samples need not be taken every day after the first day if working conditions remain consistent, but must be taken every time there is a change in the removal operation, either in terms of the location or the type of work, or during any changes in personnel.
