Subpart C—Procedures for
Changing Tariffs
§ 154.201 Filing requirements.
In addition to the requirements of
subparts A and B of this part, the following must be included with the filing
of any tariff, executed service agreement, or part thereof, that changes or
supersedes any tariff, contract, or part
thereof, on file with the Commission.
(a) A list in the transmittal letter of
the tariff sheets or sections being revised and a marked version of the
sheets or sections to be changed or superseded showing additions and deletions. New numbers and text must be
marked by either highlight, background shading, bold, or underline. Deleted text and numbers must be indicated by strike-through. Only those revisions appropriately designated and
marked constitute the filing. Revisions
to unmarked portions of the rate
schedule or tariff are not considered
part of the filing nor will any acceptance of the filing by the Commission
constitute acceptance of such unmarked changes.
(b) Documentation whether in the
form of workpapers, or otherwise, sufficiently detailed to support the company’s proposed change.
(1) The documentation must include
but is not limited to the schedules,
workpapers, and supporting documentation required by these rules and
regulations and the Commission’s orders.
(2) All rate changes in the filing must
be supported by step-by-step mathematical calculations and sufficient
written narrative to allow the Commission and interested parties to duplicate
the company’s calculations.
(3) Any data or summaries included
in the filing purporting to reflect the
books of account must be supported by
accounting workpapers setting forth
all necessary particulars from which an
auditor may readily verify that such
data are in agreement with the company’s books of account. All statements, schedules, and workpapers must
be prepared in accordance with the
classifications of the Commission’s
Uniform
System
of
Accounts.
Workpapers in support of all adjustments, computations, and other infor-

§ 154.202
mation, properly indexed and cross-referenced to the filing and other
workpapers, must be available for
Commission examination.
(4) Where a rate, cost, or volume is
derived from another rate, cost, or volume, the derivation must be shown
mathematically and be accompanied
by a written narrative sufficient to
allow the Commission and interested
parties to duplicate the calculations. If
the derivation is due to a load factor
adjustment, application of a percentage, or other adjusting factor, the pipeline must also note or explain the origin of the adjusting factor.
(5) Where workpapers show progressive calculations, any discontinuity between one working paper and another
must be explained.
