Norfolk Southern Railway Company <br />Norfolk Southern - Special Provisions for Protection of Railway Interests <br />July 23, 2018, Updated March 11, 2021 <br />Appendix <br />E-10 <br /> <br /> <br /> <br />H. Blasting: <br /> <br />1. The Contractor shall obtain advance approval of the Railroad Engineer and the <br />Sponsor Engineer for use of explosives on or adjacent to Railroad property. The <br />request for permission to use explosives shall include a detailed blasting plan. If <br />permission for use of explosives is granted, the Contractor will be required to <br />comply with the following: <br /> <br />a. Blasting shall be done with light charges under the direct supervision of a <br />responsible officer or employee of the Contractor and a licensed blaster. <br /> <br />b. Electric detonating fuses shall not be used because of the possibility of <br />premature explosions resulting from operation of two-way radios. <br /> <br />c. No blasting shall be done without the presence of the Railroad Engineer or his <br />authorized representative. At least 72 hours advance notice to the person <br />designated in the Railroad’s notice of authorization to proceed (see <br />paragraph 2.B) will be required to arrange for the presence of an authorized <br />Railroad representative and such flagging as the Railroad may require. <br /> <br />d. Have at the job site adequate equipment, labor and materials and allow <br />sufficient time to clean up debris resulting from the blasting without delay to <br />trains, as well as correcting at his expense any track misalignment or other <br />damage to Railroad property resulting from the blasting as directed by <br />the Railway’s authorized representative. If his actions result in delay of <br />trains, the Contractor shall bear the entire cost thereof. <br /> <br />e. The blasting Contractor shall have a copy of the approved blasting plan on hand <br />while on the site. <br /> <br />f. Explosive materials or loaded holes shall not be left unattended at the blast <br />site. <br /> <br />g. A seismograph shall be placed on the track shoulder adjacent to each blast <br />which will govern the peak particle velocity of two inches per second. <br />Measurement shall also be taken on the ground adjacent to structures as <br />designated by a qualified and independent blasting consultant. The Railroad <br />reserves the option to direct the placement of additional seismographs at <br />structures or other locations of concern, without regard to scaled distance. <br /> <br />h. After each blast, the blasting Contractor shall provide a copy of their drill log <br />and blast report, which includes number of holes, depth of holes, number of <br />decks, type and pounds of explosives used per deck. <br /> <br />i. The Railroad may require top of rail elevations and track centers taken before, <br />during and after the blasting and excavation operation to check for any track <br />misalignment resulting from the Contractor’s activities. <br />EXHIBIT C
