WEEKLY UNDEGROUND NATURAL GAS STORAGE REPORT
INSTRUCTIONS

PURPOSE

QUESTIONS

The U.S. Energy Information Administration (EIA) Form
EIA-912 Weekly Underground Natural Gas Storage Report is
used to collect information on weekly inventories of
natural gas in underground storage facilities, as well as
marine terminals that operate liquefied natural gas (LNG) storage.

If you have questions on the Form EIA-912, call (877) 800-5261.
If you contact to us about this report, be sure to include your EIA
identification number.

WHO MUST SUBMIT

PART 1: RESPONDENT IDENTIFICATION DATA

Form EIA-912 is mandatory under 15 U.S.C. §772(b) and must
be completed by underground natural gas storage operators
in the United States. Companies receiving notification
are statistically selected by EIA from a list of all underground
natural gas storage operators in the United States. All marine
terminals with operational LNG storage must also report.

Report period: The weekly report period refers to the week ending
on Friday at 9:00 a.m. CST. Write the month, day, and year (e.g.,
January 13, 2017 is: 01/13/2017).

WHEN TO SUBMIT

Resubmission: Enter an “X” in the resubmission box if you are
correcting information you previously reported. You must file a
revised report if the data for any region for the previous week have
been revised by 500 million cubic feet or more from the data
previously reported. Submit a revised form for that region and
indicate the appropriate report period on the form.

You must complete Form EIA-912 using information as of 9:00
a.m., Central Standard Time (CST) each Friday by 5:00 p.m.,
Eastern Time (ET), on the Monday following the end of the
report period (e.g., the Weekly Underground Natural Gas Storage
Report, as of 9:00 a.m. CST, Friday, January 13, 2017 must be
received by 5:00 p.m. ET, January 16, 2017). If Monday is a federal

base gas. Working gas may or may not be completely withdrawn
during any particular withdrawal season.

Report any non-flow related activity affecting working gas inventory
levels. Examples include reclassifications between working and base
gas levels, operational balancing agreements, or facility expansions.
Enter volumes of non-flow activity in the appropriate region(s):

DEFINITIONS
Please refer to these definitions before completing the survey form.
Base (cushion) gas: The volume of gas needed to maintain adequate
reservoir pressures and deliverability rates throughout the
withdrawal season. Base gas usually is not withdrawn, and remains
in the reservoir. All native gas is included in the base gas volume.
Reclassification: The volume representing any recorded change in
the allocation between working and base gas levels in storage based
on accounting or engineering assessments. Depending on the nature
of the reclassification and/or the regulatory authority over the
facility, respondents may or may not report reclassifications to such
authorities.

The information you provide on Form EIA-912 will be used for
statistical purposes only and is confidential by law. In accordance
