(1) At least forty-five days before starting any major construction of any pipeline intended to be operated at twenty percent or more of the specified minimum yield strength of the pipe used, the pipeline company must file a report with the commission setting forth the proposed route and the specifications for such pipeline. The report must include, but is not limited to, the following items:
(a) Description and purpose of the proposed construction;
(b) Pipe specifications and route map;
(c) Maximum operating pressure for which the pipeline is being constructed;
(d) Location and construction details of all river crossings or other unusual construction requirements encountered en route; i.e., places where pipe will be exposed or it is impractical to provide required cover, bridge crossings, lines to be laid parallel to railroads or state highways and encroachments, and other areas requiring special or unusual design and construction considerations;
(e) Corrosion control plan that includes the specifications for coating and for wrapping;
(f) Welding specifications and welding inspection methods and procedures required during construction of the pipeline;
(g) Required bending procedures; and
(h) Location and specification of all mainline block valves indicating whether the valves will be operated by manual or remote control. Indicate other auxiliary equipment to be installed as a part of the pipeline system to be constructed.
(2) For pipelines operating under twenty percent specified minimum yield strength, a pipeline company must submit to the commission a written notice at least forty-five days prior to the proposed construction. The notice must include a project description and timeline.
(3) The commission may waive the forty-five-day reporting requirement in an emergency.
