General Information
1. Purpose of data collection
Under the authority of the Natural Gas Act (15 USC 717), the Commission
promulgated 18 CFR §284.13(c) which states that each calendar quarter an
interstate pipeline must file with the Commission an index of all of its firm
transportation and storage customers under contract as of the first day of the
calendar quarter. The pipeline must also post an electronic format of this
information on its internet web site. The instructions herein will provide the
format for the electronic dissemination of the data on the respondent's web site
in a downloadable file, as well as for the electronic file submitted to the
Commission. These instructions reflect the additional filing requirements stated in
Order No. 637, issued on February 9, 2000.
2. Who must file
Each interstate pipeline regulated by the Commission that provides firm
transportation or storage service under Subparts B or G of Part 284 of the
Commission's regulations must file this information.
3. How / What to submit
The preferred method of submittal is electronic submission via eFiling.
Information for eFiling can be found at: http://www.ferc.gov/docsfiling/efiling.asp
You may submit your data file on diskette or compact disk. Please add the
respondent's name, as well as the name of the electronic file on the media label.
The diskette or CD must be accompanied by a cover letter stating the content of
the electronic filing. The cover letter must also include the subscription provided
in Part 385.2005(a). All data submitted will be considered non-confidential and
will be made available to the public upon request. There is no paper format
required for this data.
When filing a revision, be sure the report date, original/revised filing indicator,
and the filename accurately reflect that the file is a revision.
4. When to submit
The web site posting date and Commission filing date for this information is the
first business day after the start of each calendar quarter. The first day of the
calendar quarters are January 1, April 1, July 1, and October 1 of each year.

File Format Information
1. The information required for this filing must be recorded in a "TAB" delimited
format with the data ordered as specified in the Electronic Filing Format
section of these instructions. The file and the media must be Windows
compatible. An example of a "TAB" delimited file adhering to the prescribed
electronic filing formats is on page thirteen. There are three important
instructions regarding "TAB" delimited files:
a) It is imperative the respondent realizes that the "TAB" characters are
as important as the actual data coded onto the record. Without the
correct "TAB" characters on the record to locate and distinguish data
fields, the file cannot be processed. The respondent must be careful
not to use a software program to create the “TAB” delimited records
which converts the “TAB” characters into equivalent space characters.
b) If a data item is not applicable, the data item must be omitted, but the
associated "TAB" character for that item must be recorded on the
record. For example, let's assume a record consists of four data items:
Company Name
Report Year
Beginning Balance and
Ending Balance.
Further, assume that the beginning balance field is to be left blank.
Then, the structure of the reported record would be as follows:

XYZ Natural Gas Company2011123456
The double "TAB" characters denote a blank entry for the
beginning balance data item in this record.
c) You must add a hard return to the end of each line of data.
2. Each logical record should be terminated by a hard return.

4

3. All information required to be filed should be recorded in one file. The
naming convention for this file is: "INNNYYMM.TAB", where "I" is the
file name indicator used for the Index of Customers filing, "NNN" is the
three-digit FERC pipeline code for the respondent (see Item 7.A. for
information on the Pipeline ID), and "YYMM" is the two-digit year and
the two-digit beginning month for each quarterly submittal. If it is
necessary to submit revised reports, the file names should be
“INNNYYMM.TA1", “INNNYYMM.TA2", etc., where ".TA1" indicates the
first revision, ".TA2" the second revision, etc. For any revised reports,
"YYMM" must refer to the year and beginning month of the quarter to
which the revisions apply. The file name should be included in the transmittal
letter accompanying the respondent's filing.
4. The definitions, instructions, and record type formats for this electronic filing
specify explicitly the data items to be reported and the sequence for
recording each data item.
5. All fields must adhere to the following conventions for coding data on the
electronic filing:
A. In accordance with 18 CFR §284.4, all quantities must be
reported in MMBtu. If the Commission has granted the
respondent a waiver of this regulation, and the respondent
reports data in Mcf, report these volumes measured at 14.73
psia and 60 degrees Fahrenheit rounded to the nearest Mcf.
B. Do not include commas in reporting any numeric value.
6. Footnotes. Footnotes may be used to submit additional information about any
data item(s) included in this report. A "Footnote" record is provided for this
purpose.

7. Source of Codes.
A. Pipeline ID - Use the FERC three-digit code for the respondent's
pipeline. An updated list of three-digit codes is provided on the
Commission’s web site at http://www.ferc.gov/industries/gas/geninfo/pipecode.asp.
B. If your pipeline is not listed, call Tiquana Taylor at 202-502-8551 and a
Pipeline ID will be assigned.
C. Rate schedule - Report the respondent’s own designation for the rate
schedule being reported. This rate schedule name must be entered
exactly as it is reported in the FERC Forms 2 or 2-A as approved in
Oder No. 581.
D. Shipper ID - Use the unique Data Universal Number System (D-U-N-S)
Number assigned by the Dun and Bradstreet Corporation and accepted
by the North American Energy Standard Board (NAESB) as the
common code for the shipper.
E. Point Identification Code - Use the North American Energy Standards
Board/Petroleum Information Corporation (NAESB/PI) Data Reference
Number, a one-to-nine digit number also assigned by IHS (successor
to PI).
