The personal property of express, stage and transportation companies, and of pipeline companies engaged in the business of transporting natural gas, gasoline, crude oil, or other petroleum products except as otherwise provided by law, shall be listed and assessed in the county, town or district where the same is usually kept.
The personal property, consisting of the pipeline system of mains, pipes, and equipment attached thereto, of pipeline companies and others engaged in the operations or business of transporting natural gas, gasoline, crude oil, or other petroleum products by pipelines, shall be listed with and assessed by the commissioner of revenue and the values provided to the city or county assessor by order. This subdivision shall not apply to the assessment of the products transported through the pipelines nor to the lines of local commercial gas companies engaged primarily in the business of distributing gas to consumers at retail nor to pipelines used by the owner thereof to supply natural gas or other petroleum products exclusively for such owner's own consumption and not for resale to others. If more than 85 percent of the natural gas or other petroleum products actually transported over the pipeline is used for the owner's own consumption and not for resale to others, then this subdivision shall not apply; provided, however, that in that event, the pipeline shall be assessed in proportion to the percentage of gas actually transported over such pipeline that is not used for the owner's own consumption. On or before June 30, the commissioner shall certify to the auditor of each county, the amount of such personal property assessment against each company in each district in which such property is located.
