This qualified person shall be EPA Contractor/Supervisor or Project Monitor certified for asbestos projects. If monitoring outside the asbestos control area shows airborne concentrations have reached the action level, stop work, correct the condition(s) causing the increase, and notify the COR immediately. In areas where the construction of an enclosed asbestos control area is not required, after initial Time Weighted Averages (TWA's) are established, and provided the same type of work is performed, provide personal and area monitoring at the designated limits of the asbestos work area at a frequency noted in the asbestos work plan.

PART 2 - PRODUCTS

2.1 EQUIPMENT

A. Warning Signs and Labels: Provide warning signs in accordance with OSHA 29 CFR 1926.1101 at all approaches to asbestos control areas. Provide all drums, bags, wrapped components, or other similar asbestos laden containers with appropriate warning labels.

B. Back-up Generator: During abatement of friable asbestos, the contractor may be required to provide an auxiliary back-up generator to supply power automatically to negative air system should commercial power fail. This requirement will be spelled out specifically in the Statement of Work if required.

C. Local Exhaust System: Local exhaust systems (for enclose work areas) must be installed and operated in accordance with ANSI Z9.2. The contractor shall notify the COR immediately of any variance in the pressure differential which could cause exposure of adjacent unsealed areas to asbestos fiber concentrations in excess of 0.01 fibers/cc.

D. Temporary Utilities: If required, the contractor must supply water and power to the work site as necessary. In most cases, though not always, electrical power and cold water for use will be available at or within 200 feet of work site. The contractor may be required to provide electricity with an electric generator or to transport water onto the work site for use. However, hot water in quantities needed for showers will not be available and must be provided by the contractor. Location of power/water requirements to be used shall be addressed in the design plan.

PART 3 - EXECUTION

3.1 WORK AREA

A. Perform asbestos-related work in accordance with OSHA, EPA, and SC DHEC regulations, and as specified herein.

B. Asbestos Control Area Requirements: The construction of a totally enclosed asbestos control area may at times be impractical or impossible within the project limits (such as for outdoor asbestos work). When this determination is made, the contractor may submit the details of alternative control measures as part of the Asbestos Work Plan. Provide a 20-foot roped off perimeter around the area where the asbestos handling procedures are performed and maintain other requirements for asbestos control areas.

C. Control Area Requirements for Removal of Non-friable Asbestos Materials: For interior surfaces where the non-friable asbestos surface material (such as Resilient Floor Coverings, Vinyl Asbestos Tiles, or Asbestos Cement panels) can be removed intact, perform the work in accordance with applicable OSHA regulations.

D. Monitoring: Monitoring of airborne concentrations of asbestos fibers shall be in accordance with 29 CFR 1926.1101 and as specified herein using NIOSH Method 7400. The Government shall have the option to perform independent monitoring.

E. Site Inspection: While performing asbestos removal work, the Contractor shall be subject to on-site inspection by the COR who may be assisted by Government safety or environmental personnel. If the work is found to be in violation of any part of these specifications, the COR will issue a stop work order which will take effect immediately and remain in place until the violation is resolved. Standby time and expenses required to resolve the violation shall be at the Contractor's expense.

3.2 CLEARANCE SAMPLING AFTER FINAL CLEANUP

A. For asbestos abatement projects conducted with an enclosed containment area, the contractor shall perform an aggressive air sample of the area (at least three samples per removal site, with minimum volume of 2,400 liters of air per sample with a flow rate and sample time to yield a sample result that will provide statistical confidence that the air concentration is below 0.01 f/cc). Submit the results of these samples to the COR. The contractor shall not remove the containment area until written permission is received from the COR. Before authorization to tear down the containment structure will be granted, the fiber counts from all three samples must be less than 0.01 f/cc of air. If the baseline TWA, established before work began, is greater than 0.01 f/cc, then all three samples must not exceed the baseline count. Should any of the three final samples indicate a higher value, the Contractor shall re-clean the area and shall repeat the clearance process until the fiber count is equal to or below that set by the above limits. All costs associated with re-cleaning and re-testing as a result of failure to meet clearance sampling limits shall be borne by the contractor.

3.3 DISPOSAL OF ASBESTOS

A. Collect asbestos waste, scrap, debris, bags, containers, equipment, and asbestos-contaminated clothing which may produce airborne concentrations of asbestos fibers, in sealed double 6 mil plastic bags labeled in accordance with 29 CFR sec. 1910.100 (j) (2) or 1926.1101 (k) (2) (iii). The name "US Forest Service" and the location of the site where the asbestos waste was generated must be clearly and permanently affixed to the container label or wrapping. Where the asbestos material is hard or otherwise has sharp edges, the material shall be prepackaged in burlap, nylon or other material to prevent puncture of the plastic. Dispose of waste asbestos material in the approved landfill designated in the submittals. Before transporting off site, complete the required waste shipping record (WSR) and have it signed by the COR or designated government representative. No asbestos waste will be permitted to leave the site without a completed and signed waste shipping record. Upon arrival at the approved disposal site, the WSR is to be signed by the site personnel and a copy of the signed WSR is to be sent to the contractor within the time frame as required by 40 CFR 61.149(e). A copy of the returned WSR is to be provided to the COR. If the signed copy of the WSR is not received by the contractor within 35 days, the contractor must contact the site to determine the status of the waste shipment. If after 45 days a copy has still not been received, the contractor must notify U.S. EPA Regional Asbestos NESHAPS Coordinator in writing and provide the following information: (a.) A copy of the WSR for the load in question, and (b.) A cover letter signed by the contractor explaining his efforts to locate the waste shipment and the results of those efforts. Failure to comply with this or other requirements of the specification will constitute sufficient grounds for termination of this contract. For temporary storage if necessary, an area for interim storage of asbestos waste will be assigned by the COR or by an authorized representative. Procedure for hauling and disposal shall comply with 40 CFR 61, Subpart M, 49 CFR 172-177, 40 CFR 241 and 257, and state, regional, and local standards.
