If the locality and the utility enter into such an agreement, the locality shall by ordinance (a) set the boundaries of the special rate district within a reasonable distance of the route of that portion of the line to be placed underground pursuant to the agreement, and (b) fix the amount of such tax or assessment, which shall be based on the assessed value of real property within such district. Thereafter, owners of real property comprising not less than 60 percent of the assessed value of real property within such district may petition the locality to impose such tax or assessment. If such petition is filed, the locality shall submit the agreement to the State Corporation Commission on or before the date by which respondents must prefile testimony and exhibits in any application for approval of the line before the State Corporation Commission, which, after notice and opportunity for hearing, shall approve the agreement if it finds it to be in the public interest. If there exists a practicably feasible overhead alternative for construction of the electric transmission line, the State Corporation Commission shall not approve the agreement unless the governing body of every locality in which the underground segment of the line would be located requests the electric utility to construct the line underground in accordance with this subdivision. If the agreement is approved by the State Corporation Commission, the locality shall impose such tax or assessment on electric utility customers within the district, and the locality and the utility shall carry out the agreement according to its terms and conditions.
