Before a person is going to temporarily engage in work or other activity in closer proximity to a high voltage line or conductor than is permitted by AS 18.60.670, the person shall immediately notify the operator or owner of the high voltage line or conductor of the work to be performed and make appropriate arrangements, with payment satisfactory to the operator, for the installation of temporary mechanical barriers, temporary deenergization and grounding of the conductors, or a temporary raising of the conductors. Costs incurred by an operator or owner of a high voltage line or conductor in providing barriers, deenergization, and grounding as specified in this section shall be paid by the person engaging in the work that requires these protective measures.
