FERC Form 73, Oil Pipeline Service Life Data

The Commission has authority over interstate oil pipelines as stated in the Interstate Commerce Act, 49 USC 60502, et. al. As part of the information necessary for the subsequent investigation and review of an oil pipeline company's proposed deprecation rates, the pipeline companies are required to provide service life data as part of their data submissions if the proposed depreciation rates are based on the remaining physical life calculations. The information collected is used by the Commission to establish oil pipeline depreciation rates based on the physical properties of a pipeline's equipment. Depreciation rates are a factor in a pipeline's transportation cost of service. As such, companies are required to submit FERC Form No. 73 when requesting Commission approval of: (1) the establishment of depreciation rates for new pipeline equipment or (2) revision of previously approved depreciation rates, when the depreciation is based on the physical properties of the pipeline company's assets. The Commission may also request an oil pipeline company to submit a FERC Form No. 73 filing during a depreciation rate investigation.
