Colo. Rev. Stat. § 34-64-106
Any natural gas public utility, having first obtained an order from the commission which has become final, desiring to exercise the right of eminent domain for the purpose of acquiring property for the underground storage of natural gas, shall do so in the manner provided in this article. Such natural gas public utility shall present to the district court of the county wherein the land or some portion thereof is situated a petition setting forth the purpose for which the property is sought to be acquired, a description of the property sought to be appropriated, and the names of the owners of the property as shown by the records of such county. The petitioner shall file the order of the commission as a part of its petition, and no decree or rule by the court granting said petition shall be entered without such order having been filed therewith. The court shall examine said petition and determine whether the petitioner has the power of eminent domain and whether said property is necessary for its lawful purposes, and if found in the affirmative such findings shall be entered in the record. All proceedings under this section shall follow the procedure then in force and effect pertaining to eminent domain.
