(c) Transmittal letter. Letters of transmittal must give a general description of the change in depreciation rates being proposed in the filing. Letters of transmittal must also certify that the letter of transmittal (not including the information to be provided, as identified in paragraphs (d) and (e) of this section) has been sent to each shipper and to each subscriber. If there are no subscribers, letters of transmittal must so state.

(d) Effectiveness of property account depreciation rates.

(e) Information to be provided. The information in paragraphs (e)(1) through (5) of this section must be provided as justification for depreciation changes. Modifications, additions, and deletions to these data elements should be made to reflect the individual circumstances of the carrier's properties and operations. Any information in paragraphs (e)(1) through (5) of this section, the release of which would violate section 15(13) of the Interstate Commerce Act, must be provided in a format that will protect individual shippers.

(3) A table of the proposed depreciation rates by account.

(4) An explanation of the average remaining life on a physical basis and on an economic basis.

(5) The following specific background data must be submitted at the time of and concurrently with any request for the establishment of, or modification to, depreciation rates for carriers. If the information listed is not applicable, it may be omitted from the filing:

(i) Up-to-date engineering maps of the pipeline including the location of all gathering facilities, trunkline facilities, terminals, interconnections with other pipeline systems, and interconnections with refineries/plants. Maps must indicate the direction of flow.

(ii) A brief description of the carrier's operations and an estimate of any major near-term additions or retirements including the estimated costs, location, reason, and probable year of transaction.

(iii) The present depreciation rates being used by account.
