Section 70:04:05:06 - Criteria for underground pipeline facilities

The design criteria and installation standards for underground pipeline facilities are as follows:

(1) Longitudinal installations must be located as near the right-of-way line as possible. In curb and gutter highway sections, the installation may be placed under the parking lanes or, if none, the outside driving lane when it cannot be placed beyond the curb. The region engineer may grant an exception to this requirement if the utility is tying into existing pipelines;

(2) Installations must be in as straight a line as possible. Installations must indicate crossings and longitudinal occupation by means of markers or manholes placed as shown on the approved utility permit;

(3) Crossings of paved surfaces must be made by boring or jacking, unless the region engineer determines diminished pavement condition, existing pipelines or other mitigating conditions make boring or jacking unnecessary. Boring or jacking must be continuous from toe of inslope to toe of inslope or back of curb to back of curb. Crossings of gravel or unpaved surfaces may be made by open trench;

(4) Pipeline crossings carrying hazardous materials, rural pipeline crossings carrying nonhazardous materials, pipeline crossings with diameters of six inches or more, and pipeline crossings operating at pressures of eighty pounds per square inch gauge or more must be encased. However, welded steel pipeline crossings may be installed without encasement provided that the crossings meet the following requirements:

(a) Have increased wall thickness or higher strength steel or both;

(b) Have increased depth of cover;

(c) Are marked in accordance with subdivision (2) of this section; and

(d) Are designed to withstand internal design pressures and the superimposed loads of the roadway and traffic, including that of construction machinery;

(5) Pipelines carrying hazardous materials must conform with 49 C.F.R. §§ 192.1 et seq. (August 15, 2024), or 49 C.F.R. §§ 195.0 et seq. (August 15, 2024), as applicable;

(6) The minimum depth of cover over the installations to the surface is four feet under rural roadway sections, two feet under curb and gutter roadway sections, and three feet under other areas within the right-of-way;

(7) Open cut installations must be performed in compliance with the "Open Cut Method of Utility Installation or Repair," pursuant to Appendix A of this chapter; and

(8) The location of manholes and longitudinal pipelines must be in accordance with the Guide for Accommodating Utilities within Highways and Freeways, First Edition.
