Permits for pipelines installed within State, Railroad and County right-of-way shall be obtained by the Owner. All work performed within State, Railroad and County right-of-way shall be completed according to the requirements contained in the permits of the appropriate agency or company. For installation in railroad owned property, the Contractor shall first determine and then obtain all necessary insurance to the minimum coverage requirements, as required by the railroad, in order to perform work within the railroad property. The Contractor shall also, when required, execute any Agreements with the railroad to perform work within its right-of-way.
(Ordinance 2007-106, App. B, adopted 3/20/07)
A. 
Casing or Carrier Pipe by Bore or Tunneling.
Installation by bore or tunneling of casing or carrier pipe shall be true to line and grade. The Contractor shall conform to the permit requirements of the appropriate Agency as to the construction methods used. After pipeline installation, immediate backfilling shall be performed on all pits and trenches excavated for the boring operation. For excavations performed by tunneling and jacking, the excavation for the underside of the pipe for at least one third of the circumference of the pipe shall conform to the contour and grade of the pipe.
B. 
Grout Around Casing or Carrier Pipe.
If the bored or tunneled hole exceeds the outside diameter of the casing pipe or the outside diameter of the carrier pipe barrel by more than one inch, the space between the outside wall of the casing and the excavation shall be completely filled with grout consisting of 1 part of Portland cement to 3.5 parts of clean sand by volume. This requirement does not apply to carrier pipes installed by bore under trees unless the hole exceeds the diameter of the pipe bell by more than one inch.
C. 
Installing Carrier Pipe in Casing.
1. 
Casing spacers shall be installed on the carrier pipe. The spacers shall be installed in accordance with the pipe manufacturer’s recommendations to prevent the pipe from bearing on the bells, to position the pipe within the casing, and to prevent floating within the casing if the casing is filled with water. Casing spacers shall be installed such that the distance between the spacers does not exceed the maximum distance recommended by the manufacturer of the carrier pipe and by the spacer manufacturer dependent on potential weight of the carrier pipe full of water, except the distance between spacers shall not exceed seven (7) feet. A casing spacer shall be installed within one (1) foot of the end of each joint of nonwelded carrier pipe, and two adjacent spacers shall be installed on the carrier pipe at each end of the casing such that the last spacer is within one (1) foot of the end of the casing.
2. 
Lubricants such as flax soap or drilling mud may be used when installing the carrier pipe. No petroleum products shall be used for this purpose. After installation is completed on the carrier pipe, the ends of the casing shall be sealed with a mechanical casing seal.
D. 
Installing Split Steel Casing on Existing Carrier Pipe.
[1]
1. 
Installation of split steel casing shall follow the same general procedures for installing carrier pipe in casing, except that the casing shall be rejoined with a continuous weld, thereby making the steel casing water tight.
