30 V.S.A. § 7006b: Excavation area precautions

Any person engaged in excavating activities in the approximate location of underground utility facilities marked pursuant to section 7006 of this title shall take reasonable precautions to avoid damage to underground utility facilities, including any substantial weakening of the structural or lateral support of such facilities or penetration, severance, or destruction of such facilities. The person engaged in excavation activities shall expose underground facilities to verify their location and depth, in a safe manner, at each location where the work will cross a facility and at reasonable intervals when paralleling an underground facility. Powered or mechanized equipment may only be used within the approximate location where the facilities have been verified.
