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 underground facility owners with 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 notification service shall be funded by all of the underground facility owners required by the provisions of this section to participate in and cooperate with the service. Each underground facility owner required to participate in a one-number notification service is subject to the jurisdiction of the damage prevention board established in section 55-2203, Idaho Code, and shall maintain accurate contact information, updated at least annually, with the one-number notification service for individuals responsible for the operation of the underground facilities of the underground facility owner, including contact information for individuals responsible for responding to an emergency.
