General rate proceeding filings for marine pilotage services must include the information described in this section. The commission may reject a filing that fails to meet these minimum requirements, without prejudice to a petitioner's right to refile its request in conformance with this section.

When the filing is suspended and a hearing scheduled the petitioner must file with the commission one paper copy and an electronic copy for all testimony and exhibits that the petitioner intends to present as its direct case. The electronic copy of all filed material must be in the format identified in WAC 480-07-140(6). The commission may require the petitioner to file additional paper copies if the commission suspends and conducts a hearing on the filing.

(2) Proposed tariff. Proposed tariff sheets must be filed in electronic form supplemented by one paper copy. The proposed tariff sheets should be in legislative format (i.e., with strike-through to indicate the material to be deleted or replaced and underlining to indicate the material to be inserted) consistent with the requirements in WAC 480-160-110 through 480-160-140, as well as copies of any tariff sheets that are referenced in the new or amended tariff sheets.

(j) At the time the petitioner makes its general rate case filing, the petitioner must provide to commission staff one paper and one electronic copy of all supporting work papers of each witness in a format as described in this subsection. When the filing is suspended and a hearing scheduled, if the testimony, exhibits, or work papers refer to a document including, but not limited to, a report, study, analysis, survey, article or decision, that document must be included as a work paper unless it is a reported court or agency decision, in which case the reporter citation must be provided in the testimony. If a referenced document is voluminous, it need not be provided, but the petitioner must identify clearly the materials that are omitted and their content. Omitted materials must be provided or made available if requested by the commission.

(k) Organization. Work papers must be plainly identified and well organized, and must include an index and tabs. All work papers must be cross referenced and include a description of the cross referencing methodology.

(l) Electronic documents. Parties must provide all electronic files supporting their witnesses' work papers.

Electronic files that support the exhibits and work papers must be provided using logical file paths, as necessary, by witness, and using identifying file names.

Commission approval of a settlement does not constitute commission acceptance of any underlying methodology unless so specified in the order approving the settlement.
