Minnesota Statutes § 216D.05 - PRECAUTIONS TO AVOID DAMAGE

(a) An excavator must: (1) plan the excavation to avoid damage to and minimize interference with underground facilities in and near the construction area; (2) for proposed excavations, use (i) white markings or black markings in wintery conditions, or (ii) electronic marking as provided in paragraph (b); (3) maintain a clearance between an underground facility and the cutting edge or point of any mechanized equipment, considering the known limit of control of the cutting edge or point to avoid damage to the facility; (4) provide support for underground facilities in and near the construction area, including during backfill operations, to protect the facilities; and (5) conduct the excavation in a careful and prudent manner. (b) An excavator may use electronic marking under paragraph (a), clause (2), if: (1) the marking provides at least as much proposed excavation information as equivalent physical markings; and (2) electronic marking used prior to January 1, 2026, is accompanied by equivalent physical markings as provided under paragraph (a), clause (2). (c) Following submission of electronic marking, an operator may require the excavator to use physical markings.
