No excavator may begin any excavation without first notifying the one-call notification center of the proposed excavation. The excavator shall give notice by telephone or by other methods approved by the board pursuant to rules promulgated pursuant to chapter 1-26 to the one-call notification center at least forty-eight hours prior to the commencement of the excavation, excluding Saturdays, Sundays, and legal holidays of the state. The board may promulgate rules to reduce the forty-eight-hour interval for emergency or subsequent inquiries to the original locate request and may lengthen the forty-eight-hour interval for nonexcavation requests.
