Mississippi Code Title 77. Public Utilities and Carriers § 77-13-11

(1) The advance notice provisions of this chapter shall not apply to any person making an excavation at times of emergency involving danger to life, health or property or a customer service outage. However, every person who shall engage in such emergency excavation shall take all necessary and reasonable precautions to avoid or minimize interference with or damage to existing underground utility lines and underground facilities in and near the excavation area, and shall notify as promptly as reasonably possible the operators of underground utility lines or underground facilities in and near the emergency excavation area specifically designating whether such excavation is an emergency excavation as defined herein. In the event of damage to or dislocation of any underground utility lines or underground facilities caused by any such emergency excavation work, the person responsible for the excavation shall immediately notify the operator of the damaged or dislocated underground facilities of the damage or dislocation.

(2) An imminent danger to life, health, property or customer service exists whenever there is a substantial likelihood that injury, loss of life, health or customer services, or substantial property loss could result before the person responsible for the excavation or demolition can fully comply with the notification and response procedures required in Sections 77-13-7 and 77-13-17.
