General Order 64-A

Section III

General Provisions

31.3    Avoidance of Conflicts and Crossings.

In locating and constructing lines efforts shall be made to avoid creating any conflicts with other lines.  Where it is not reasonably practicable to maintain a sufficient separation of the lines, conflicts may in many cases be avoided by means of joint pole construction.

In the construction of new lines care shall be taken to avoid all unnecessary crossings.  Crossings requirements are covered in Sections X, XI and XII.

Supply and communication lines other than lines on jointly used poles, shall not occupy the same side of the road (fence line construction excluded, i.e., where the fence is used as all or part of the supporting structure) unless the consent of existing party or parties is obtained, or where both sides of the road are already occupied by the same class of line.

Class H circuits shall not occupy both sides of thoroughfares except where special permission is obtained from the Railroad Commission.

Where co-linear lines are created and the existing center line pole location is maintained by the constructing party, clearance arms shall be installed unless the pole separations are less than 10 feet, or the minimum horizontal clearance of wires in the lower line from the center line of pole is increased by 50%.

Where co-linear lines are created and existing center line pole location is not maintained by the constructing party clearance arms shall be installed unless the horizontal distance between lines is not less than the requirements of Table 2, Case 1 to 7 inclusive, for the highest voltage involved or the vertical distance between wires on separate lines is not less than the requirements of Table 2, Cases 1 to 7 incl. For the highest voltage involved, in which case the horizontal separation between the lower line and the face of the pole of the upper line is at least 50% greater than the center line pole clearance required of the highest voltage circuit concerned on either pole.
