2.5 AIR SAMPLING

Sampling of airborne concentrations of asbestos fibers shall be performed in accordance with 29 CFR 1926.1101 and as specified herein. Sampling performed in accordance with 29 CFR 1926.1101 shall be performed by the PQP. Sampling performed for environmental and quality control reasons shall be performed by the PQP. Unless otherwise specified, use NIOSH Method 7400 for sampling and analysis. Monitoring may be duplicated by the

Government at the discretion of the Contracting Officer. If the air sampling results obtained by the Government differ from those results obtained by the Contractor, the Government will determine which results predominate.

2.6 SAMPLING PRIOR TO ASBESTOS WORK

The Contractor’s representative shall provide area air sampling and establish the baseline prior to the masking and sealing operations for each removal site. Establish the background by performing area sampling in similar but uncontaminated sites in the building.

2.7 SAMPLING DURING ASBESTOS WORK

The PQP shall provide personal and area sampling as indicated in

29 CFR 1926.1101 and governing environmental regulations. In addition, provided the same type of work is being performed, provide area sampling at least once every work shift close to the work inside the enclosure, outside the clean room entrance to the enclosure, and at the exhaust opening of the local exhaust system.

If sampling outside the enclosure shows airborne levels have exceeded background or 0.01 fibers per cubic centimeter, whichever is greater, stop all work, correct the condition(s) causing the increase, and notify the Contracting Officer immediately.

2.8 SAMPLING AFTER FINAL CLEAN-UP (THIRD PARTY CLEARANCE

SAMPLING)

After the work area has been rendered free of visible residues and inspected, clearance sampling may begin by a Third Party

Contractor.

The Phase Contrast Microscopy (PCM) samples shall be tested in accordance to the NIOSH 7400 method. Final air clearance shall not be achieved until all samples taken are equal to or less than 0.01 fibers/cubic centimeter (f/cc).

A copy of the clearance sampling analysis shall be submitted to the Contract Inspector to give to the DPW Environmental Division

Office for review and approval prior to any further testing or tear down of the abatement area.

If the clearance sampling results are greater than 0.01 f/cc then the barrier (room) shall be re-cleaned using wet methods and HEPA vacuum(s). Another round of clearance samplings and re-cleanings shall continue until all samples taken are equal to or less than 0.0.1 f/cc.

2.9 TITLE TO MATERIALS

All waste materials, except as specified otherwise, shall become the property of the Contractor and shall be disposed of as specified in applicable local, State, and Federal regulations and herein.

3.0 DISPOSAL OF ASBESTOS

3.0.1 Procedure for Disposal

The Contractor shall collect asbestos waste, asbestos contaminated water, scrap, debris, bags, containers, equipment, and asbestos contaminated clothing which may produce airborne concentrations of asbestos fibers and place in sealed fiber-proof, waterproof, non-returnable containers (e.g. double plastic bags 6 mils thick, DOT cartons, DOT drums or DOT cans).

Wastes within the containers must be adequately wet in accordance with 40 CFR 61-SUBPART M.

The Contractor shall properly dispose of all Non-Friable ACM floor tile in an approved Sanitary Landfill which knowingly accepts ACM. All disposal costs shall be the responsibility of

Contractor.

Once the waste has been properly containerized and the load is ready to be shipped off Fort Leavenworth, Kansas, property, the

Contractor shall notify the Contracting Officer who shall then notify DPW Environmental Division Office, (913) 684-3307, to inspect each individual load and the completed but yet unsigned

Bill of Lading (Waste Shipment Paper). If approved, DPW Environmental Division Office shall sign the paperwork and the contractor can ship the waste off Post property.

Sealed plastic bags may be dumped from drums into the burial site unless the bags have been broken or damaged. Damaged bags shall remain in the drum and the entire contaminated drum shall be buried. Uncontaminated drums may be recycled. Workers unloading the sealed drums shall wear appropriate respirators and personal protective equipment when handling asbestos materials at the disposal site.

3.1 ASBESTOS WASTE SHIPMENT REPORT

The Contractor shall notify the Sanitary Landfill and inform the

Sanitary Landfill that the Contractor shall be placing ACM in the designated Asbestos special waste area of the landfill. The

Contractor shall attain a Waste Shipment Record from the

Sanitary Landfill for each load of ACM placed in the landfill and turn in a copy of the signed by the landfill Waste Shipment

Record to the Contracting Official.
