(1) At least one hour prior to the commencement of the proposed excavation, horizontally locating its utility lines at the site, and notifying the contractor that this marking has been accomplished; or
(2) Notifying the contractor that the proposed excavation will not affect its existing utility lines. (Ord. 91-04. Passed 3-5-91.)
(b) Horizontal location of utility lines at the site of excavation shall consist of a permanent marking system approved by the Office of Pipeline Safety of the U.S. Department of Transportation, or the State Corporation Commission of Virginia, or a temporary marking system approved by the Director of Building and Development, clearly and definitely indicating the horizontal location of the operator's facilities.
(Ord. 91-23. Passed 9-17-91.)
(c) In order to expedite horizontal location of utility lines, each operator shall:
(1) Provide locating services to mark all facilities affected by the excavation;
(2) Provide to designing engineers horizontal location data on its utility lines prior to field survey for designing new work so that such information on existing utility lines may be included in survey notes;
(3) Have the option to allow the locating crew of another operator to horizontally locate said facilities, provided that clearance to do so has been given in writing; and
(4) Indicate the horizontal location of their utility lines on a site map if requested by the contractor.
(d) When trenches excavated for the installation of gas pipelines are backfilled, a continuous tape, or similarly effective device, shall be installed above all direct burial plastic mains, services, stubs and stub extensions. The tape shall not be less than three inches wide, brilliant in color and imprinted with words clearly defining the utility line as “GAS”. The tape shall be impregnated with metal so that locating equipment can readily pick it up. The remainder of the backfill shall be placed in a manner that equals the original condition.
(e) When repairs are made to underground gas pipelines, and/or the tape and related requirements as provided in subsection (d) hereof have been disrupted and severed during excavation, such tape shall be installed or replaced at the completion of repairs prior to backfilling.
(f) An operator who receives notification of a proposed demolition pursuant to Section 1024.08(a) shall insure clearance for demolition by:

(2) Advising the contractor of the appropriate means of assuring adequate protection for its other utility lines in the vicinity which might be subject to unusual stress during demolition; and
(3) Notifying, or causing to be notified, the contractor that such disconnection has been accomplished or that his or her utility lines will not be affected by such demolition.
(g) If a utility line operator cannot mark the location of its underground lines at least one hour before the proposed excavation or demolition is scheduled to begin, the operator shall notify the contractor of the date and time when the line will be marked. This date shall not exceed three working days after the original scheduled work date. (Ord. 91-04. Passed 3-5-91.)
