1. 1. Except as provided in sections 319.030 and 319.050, a person shall not make or begin any excavation in any public street, road or alley, right-of-way dedicated to the public use or utility easement of record or within any private street or private property without first, when necessary to determine proximity to underground facilities, giving notice to and obtaining information concerning the possible location of any underground facilities which may be affected by said excavation from each and every owner and operator of underground facilities whose name appears on the current list of the recorder of deeds in and for the county in which the excavation is to be made. The notice referred to herein shall comply with the provisions of section 319.026.
2. 2. An excavator's notice to a notification center shall be deemed notice to all owners and operators of underground facilities represented by such notification center. An excavator's notice to owners and operators of underground facilities who are represented by a notification center according to the current list of the recorder of deeds is ineffective for purposes of subsection 1 of this section unless given to such notification center. The notice required by subsection 1 of this section shall be given directly to owners or operators of underground facilities who are not represented by a notification center.
3. 3. If the excavator is engaged in trenching, ditching, drilling, well-drilling or -driving and, if upon notification by the excavator as provided under section 319.026, the owner or operator notifies the excavator that the area of excavation cannot be determined from the description provided by the excavator, the excavator shall mark the proposed area of excavation prior to marking of location by the owner or operator of the facility.
