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 also provided. There are two 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
(ASCII 0-decimal of 00 – hexadecimal).
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 Company<TAB>2011<TAB><TAB>123456
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 carriage return (CR)
character (ASCII character – 13 decimal, 0D – hexadecimal and line feed
(LF) character (ASCII character 10 – decimal, 0A – hexadecimal).
3. All information required to be filed should be recorded in one file. The
naming convention for this file is: "ICNNNNNNYYMM.TAB", where "I" is
the file name indicator used for the Index of Customers filing, "CNNNNNN"
is the seven-character 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
indicates the first revision, ".TA2" the second revision, etc. For any
revised reports, "YYMM" must refer to the year and beginning month of
- 4 -
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.
