Every person owning or operating underground utility lines or underground facilities shall, upon receiving advance notice of the commencement of excavation, in accordance with Section 77-13-7, make an investigation, and may report through the use of the PRIS the status of the work performed, within two (2) working days from the time notice is provided in accordance with this chapter to Mississippi 811, Inc., to determine the approximate location of its underground utility lines or underground facilities in the area of the proposed excavation, and shall either: (a) mark the approximate location of underground utility lines and underground facilities in or near the area of the excavation, so as to enable the person engaged in excavation work to locate the lines and facilities in advance of and during the excavation work; (b) advise in writing or by telephone or electronic means that it has no underground utility lines or underground facilities in the excavation area; or (c) advise in writing or by telephone or electronic means that it can locate its underground utility lines or underground facilities in the excavation area only by excavation. If an operator can locate its underground utility lines or underground facilities in the excavation area only by excavation and has given proper notice of such, that operator shall be allowed a reasonable amount of additional time, not to exceed four (4) working days from the day the original notice was provided in accordance with this chapter, to mark the approximate location of the underground utility lines or underground facilities. In lieu of such marking, the operator may request to be present at the site upon commencement of the excavation, so long as the operator complies within two (2) working days of the receipt of the notice. When an excavator, upon arriving at an excavation site, sees evidence of unmarked underground utility lines or underground facilities or encounters an unmarked underground utility line or underground facility on an excavation site after excavation has commenced where notice of intent has been made in accordance with the provisions of this chapter, that excavator must immediately contact Mississippi 811, Inc. All operator(s) thus notified must contact the excavator within four (4) hours and inform the excavator of any of their known underground facilities, active or abandoned, at the site of the excavation. When marking the approximate location of the facilities, the operator shall follow the color code designated and described herein, unless otherwise provided for by specific administrative rule or regulation promulgated pursuant to this chapter, namely: Click to view All utility facilities installed by owners or operators of utilities on or after January 1, 2010, shall be installed in such manner that the utility facility may be located by using a generally accepted electronic locating method. Except for emergency excavations, if, before the expiration of the two (2) working days’ waiting period, all identified facility owners or operators have responded to the locate request and all have indicated that their facilities are either not in conflict or have been marked as indicated through the use of the PRIS, then the person planning to perform excavation or blasting shall be authorized to commence work, subject to the other requirements of this section, without waiting the full two (2) working days. Upon receiving a design information request, the utility owner or operator shall within seven (7) working days from the time notice is provided in accordance with this chapter to Mississippi 811, Inc., respond by one (1) of the following methods: (a) marking the approximate location of its underground utility lines and underground facilities in the area in accordance with subsection (1) of this section; (b) providing to the person making the design information request the best available description of its underground utility lines and underground facilities in the area which may include drawings or other records maintained by the utility owner or operator; or (c) allowing the person making the design information request or any other authorized person to inspect or copy the drawings or other records for all underground utility lines and utility facilities in the area.
