ST9302-CS 980803MEMORANDUM To.' From: Pete Smith, City Attorney Kenneth M. Griffin, P.E., Director of Engineering and Public Works Lone Star Gns Frnnehise Agreement Ordln~nce No. 96743 Date: August 3, 1998 I have received a letter from TU Services concerning the lowering of a 16" gas transmission line that is in conflict with Sandy Lake Road improvements. Their letter is requesting payment in the amount of $318,700 for lowering of the gas transmission line that is in conflict with the roadway. A copy of the letter is attached for your purposes. In my reading of the franchise agreement that was approved in September of 1995, Section lA states that it covers not only distribution but also gas transmission lines and any other associated equipment. Section 4, entitled Relocation, states that when the Grantee is required by the City to remove or relocate its mains, laterals, and other facilities to accommodate construction of streets, that the cost is borne by the Grantee. In reading the franchise agreement, I do not find where existing lines, either distribution or transmission, h'regardless of whether they are in easements to Lone Star Gas, or whether or not they supersede our right-of-way, are exempted from this franchise agreement. In conversations with Lone Star Gas or TU Services, their initial position is that their easement was obtained in 1915, and that it supersedes our roadway and therefore, they have prior rights and the City should pay for the relocation of the transmission line. I am also sending a letter to TU Services requesting that they reread the franchise agreement and lower the gas transmission main on the basis of the franchise agreement at their cost, not the City's. With this memo, I am requesting that you review the franchise agreement, and offer your opinion on whether or not a gas transmission line located in an easement obtained in 1915 that crosses the right- of-way of Sandy Lake Road is exempted from the franchise agreement, and by virtue of being exempted, it requires the City to pay for the relocation. Obviously, it is important for Lone Star Gas to lower the gas line during the summer months, so therefore, it is important that we take a definitive position as soon as possible. If you have any questions, or need additional clarification or information, please feel free to contact me at your convenience. cc: Clay Phillips, Deputy City Manager JL/L 13 ~98 O~:~gPM KIMW~-HOR~ FT WORTH P. 6/11 Greg D.

The south side of thc roadway has an existing concrete parking area with gasoline tanks. The north side is an open area. To provide adequate clearance between LSP's proposed pipeline and the 30-inch water line, LSP must place the 16" pipeline approximately 27 feet below the existing grade. Due to other obstructions (water lines, RCP, etc), it is not possible to place the new pipeline above the 30-inch water line as you can see on the drawing MU$-0$1. In order to place this new pipeline 27 feet below the surface, the only construction technique is to directional drill. Other construction techniques are not practical for this situation. The pipe-bending radius must be limited in order to prevent the line from being overstressed at the required maximum working pressure, in this case 800 psig. The proposed design uses Grade X-60 pipe in order to use the tightest safe bending radius. After nmerous engineering calculations, a 628 foot (measured horizontally) directional bore is required. With the added pipe required to traverse along thc curve and tie back in to the existing pipeline, approximately 720 feet of pipe is required. The existi, ng easement on the south side is 15 feet (7-1/2 feet each side of existing pipeline)- It is unsafe to replace a pipeline within this e~ement; therefore a new 15 foot permanent casement will be required east of the existing easement. Temporary easement will be required on both the north and south sides to accommodate the boring operation. In addition, LSP will need to close the street for one day going into the subdivision on the north side. We may also n~d to close one lane of northbound Moore Koad (north side of Sandy Lake Road) to accommodate this project. Please advise what requirements the City of Coppell has for strect closings/traffic detours.
