Idaho Code § 55-2206

Two (2) or more persons who own or operate underground facilities in a county may voluntarily establish or contract with a third person to provide a one-number notification service to maintain information concerning underground facilities within a county. Upon the establishment of the first such one-number notification service, all others operating and maintaining underground facilities within said county shall participate and cooperate with the service, and no duplicative service shall be established pursuant to this chapter. The activities of the one-number locator service shall be funded by all of the underground facility owners or operators required by the provisions of this section to participate in and cooperate with the service. All underground facility owners or operators who are required to participate in a one-number notification service are subject to the jurisdiction of the damage prevention board established in section 55-2203, Idaho Code.
