1. DESCRIPTION

1.1 GENERAL

The Contractor shall furnish all services, permits, materials, supplies, labor, equipment, supervision, travel, and any and all other services as required for cleaning dust containing asbestos from ventilation systems, and disposal services necessary to complete this Scope of Work (SOW). The Contractor, its subcontractor(s) and appropriate employee(s) of each, shall be responsible for obtaining and maintaining any registration or certification as required by Federal, state of Montana, and local regulatory agencies, and any other licenses, permits, or other credentials or permissions required to perform these tasks. It is the Contractor’s sole responsibility for timely notification of such actions to Federal, state, or local agencies as required. The Contractor shall obey all laws and regulations of the United States and the state and local governments having jurisdiction over the activities addressed in this SOW regarding the removal, storage, transportation, and disposal of all material. Where the requirements of this specification and Federal, state, Regional or local regulations vary, the most stringent requirements shall be enforced. The government will not be responsible for the penalties or fees which are incurred as a result of contractor negligence.

Extensive sampling for asbestos was conducted from July 2019 through February of 2020 to determine the potential for employee exposure in the Libby Dam Powerhouse. It was determined that the dust in the Powerhouse does contain chrysotile structures. While the source of the structures has not been determined one potential source could have been asbestos in brake shoes in the units contributed in the dispersion of structures throughout the Powerhouse. The concentrations of structures in the dust are presented in Table X, The State of Montana determined that chrysotile in dust does not meet the requirements of an asbestos containing material and is therefore not regulated nor is considered an Asbestos Project per State rules. Libby Dam employees use best management practices when cleaning up dusty areas prior to work to reduce potential for employee exposure.

To evaluate potential employee exposure a significant amount of air samples have been conducted by Project staff, and OSHA in varying situations to determine airborne concentrations. All air samples conducted for time weighted averages for an 8 hour workday and 30 minute short-term sampling resulted in concentrations well below the personal exposure limit set by OSHA. It is imperative that the cleaning of debris from the Powerhouse ventilation system that best practices are put in place to minimize to the extent of possible the disruption of dust into the general atmosphere. Contractor employees should be aware of the situation of structure in the dust and protect themselves accordingly.

In addition, original construction specs indicate that an asbestos acoustic cloth was used to line the interior of the ventilation system. The cloth was abated by an asbestos contractor in the early 90's.

However, if the contractor does come across suspect material in the duct work that may have been missed during abatement, they should stop work and notify the Contracting Officer Representative immediately to evaluate the situation and work on a path forward to have the material abated properly if necessary.

Appendix C contains multiple data reports regarding the site conditions. The contractor will utilize best management practices and utilize the data to determine factors regarding worker protections and waste disposal.

The Contractor shall supply personnel with sufficient training and certification to perform all tasks accordance with all applicable laws and regulations. At a minimum, the work shall be supervised by an individual who meets the definition of a competent person in accordance with 29 CFR 1926.62 and 29 CFR 1926.1101, and all workers shall be provided asbestos awareness training in accordance with 29 CFR 1910.1001/29 CFR 1926.1101 and training in accordance with 29 CFR 1910.1025/29 CFR 1926.62. Libby Dam Project is an active facility with operational and security requirements for various activities. The Contractor will be subject to these limitations relative to coordination of activities, schedule, training and access, and will be responsible for all costs associated with complying with these restrictions.

The Contractor shall ensure the work is conducted in a manner that protects the safety and health of its employees, government employees, and members of the public; and that it complies with all current Occupational Safety and Health Administration (OSHA) and US Army Corps of Engineers (USACE) health and safety requirements.

Due to COVID-19 concerns and stringent timetable for Award and executing this contract a pre-bid site visit will not occur. Drawings have been provided of the system such that the project will be biddability purposes. See Appendices A and B.

Due to the security requirements of the project, limited photos and drawings are available of the powerhouse. A pre- bid site visit will be scheduled before bid due date. It is suggested that the contractor attend the pre-bid site visit in order to prepare a competitive bid. Failure to attend the site visit does not constitute a change in conditions.
