Where it becomes necessary to excavate beyond the normal lines of excavation to remove boulders or other interfering objects, the voids remaining after such materials are removed shall be back-filled with suitable material approved by SCRRA. The material obtained from the project excavation may be suitable for use as fill or backfill at the discretion of SCRRA. Any excess material must be disposed of by hauling off-site. The excess material must not be piled-up or scattered on the right-of-way. 4.1.2 The Contractor shall perform excavation and grading so that the finished surfaces are in uniform planes with no abrupt breaks in surface and having positive drainage on the right-of-way away from the track structure. 4.2 Utilities 4.2.1 The Contractor is responsible for the location and protection of any and all surface, sub- surface, and overhead utilities and structures. Approval of the project and the Right-of- Entry agreement by SCRRA and/or Member Agency does not constitute a representation as to the accuracy or completeness of location or the existence or non-existence of any utilities or structures within the limits of this project. The Contractor shall notify the appropriate regional notification center [Underground Service Alert (D1GALERT) at (800)-227-2600], railway companies, and utility companies prior to performing any excavation close to any underground pipeline, conduit, duct, wire, or other structure.

In case of signal emergencies or grade crossing problems, the Contractor shall call SCRRA's 24-hour signal emergency number (888) 446-9721. 4.2.2 There are oil, gas, and fiber optic lines running along most of the right-of-ways.
