Non-Dominant Carriers Log The Non-Dominant directory contains files of weekly publications listing tariff filings of non-dominant domestic carriers. These publications are entitled TARIFF TRANSMITTAL PUBLIC REFERENCE LOG Non-Dominant Carriers. The file names follow the format "ndMMDDYY.pdf" where the MMDDYY refers to the month, day, and year of the log's published date. Read the pdf_help.txt file in this directory for information on the Adobe Acrobat (PDF) format and its use. These logs list domestic tariffs filed by nondominant carriers, such as MCI, SPRINT and various resale carriers offering interstate long distance services. (When such domestic services are combined with international services within a single tariff, those tariff filings are listed in the Operator directory). The files in the Non-Dominant directory contain unofficial lists of tariff transmittals (and related information) received by the OPA-ROD, Tariff Public Reference Room,and are available for inspection and copying along with the related transmittals in the Public Reference Room (Room 250), which is on the second floor at 1919M Street, N.W., here in Washington, D.C. It is open to the public from 1:30-4:30 pm on normal business days when the FCC is open for business. These lists are prepared for staff use and are released for the convenience of the public. The Commission does not guarantee the completeness or accuracy of these lists. You may obtain copies of existing tariffs and related tariff material by making arrangements with the FCC's commercial duplicating contractor (located in Room 246) and copying the material yourself, or you may have the contractor make the copies for you, for a fee. The contractor can also ship or fax tariff and other materials filed with the Commission, as well as documents published by the Commission. Copies also are available for purchase through recognized distribution services. Questions regarding tariff availability may be directed to 1-202-418-1933 (Tariff Public Reference Room).
