PART 1 GENERAL

The following asbestos-containing materials are present in the project area and impacted by the project work. Remove, handle, and dispose of these materials as required by this specification section and applicable regulations.

Cloth jacket wire that is scheduled to be removed for this project should be assumed to be covered with non-friable asbestos-containing insulation. It is expected that the insulation is in good condition. It is not anticipated that the removal activities required for the project will cause the wire insulation to become friable, disrupt the matrix of the asbestos-containing material, or generate the release of asbestos fibers; however a negative exposure assessment for this work is not available.

Cable trays in the cable tunnel to switchyard 1 are assumed to consist of transite asbestos. These cable trays are scheduled to be removed and replaced as part of this project. See drawings ED102 and E-102 for location of the cable trays. In addition, the cable tray brackets are assumed to contain lead-based paint and are required to be removed as part of the project. See specification Section 02 83 00 LEAD IN CONSTRUCTION for handling requirements for the brackets.

A ceiling partition consisting of transite asbestos is present in the first part of the cable tunnel for KV7A's feed. See drawing ED102.

In switchyard 1, the Riser 1 access panels may contain asbestos. Assume that the panels contain asbestos unless they are tested and demonstrated to be asbestos-free.

In the cubicle room there is insulation around the HVAC ducting located on the ceiling that may contain asbestos. Work on the HVAC system is not included in this project although project tasks may require working in close proximity to the HVAC system and its insulation. This insulation is not scheduled for removal as part of this project. The Contractor shall take appropriate steps to prevent disturbing or damaging this material while performing the required project tasks.

If any other materials that must be disturbed or removed as part of the work appear suspect for asbestos, the Contractor shall consult with the KO, and sample the material as needed and have it analyzed using Polarized Light Microscopy (PLM) for asbestos content. The laboratory shall be accredited by the National Institute of Science and Technology (NIST) under National Voluntary Laboratory Accreditation Program (NVLAP)and shall comply with all applicable Federal and Montana regulations for asbestos analysis. The Contractor shall utilize a third-party asbestos inspector trained and accredited in accordance with applicable Federal and State of Montana laws and regulations for all asbestos inspection and sampling activities. The accredited inspector shall comply with all applicable requirements of Montana rule 17.74 Subchapter 3. Work procedures and disposal of asbestos-containing materials shall be performed in accordance with this specification and applicable regulations.
