MONTHLY NATURAL GAS STORAGE REPORT
FORM EIA-191
INSTRUCTIONS
PURPOSE

HOW TO COMPLETE THE SURVEY FORM

The U.S. Energy Information Administration (EIA) Form EIA-191
Monthly Natural Gas Storage Report provides data on the
operations of all active storage facilities. The data appear in
the EIA publications Monthly Energy Review, Natural Gas Annual,
and Natural Gas Monthly.

Report all volumes in thousand cubic feet (Mcf). Do not report any
negative values on any part of the Form EIA-191 or Form EIA-191L.

WHO MUST SUBMIT
Form EIA-191 is mandatory under 15 U.S.C. §772(b) and must be
completed by all companies that operate underground natural gas
storage fields or liquefied natural gas (LNG) storage facilities in the
United States must provide the information requested. Operators
of underground storage facilities must complete Form
EIA-191.
Operators of LNG storage facilities must complete
Form EIA-191L.

Provide data for all fields your company operates. You may copy
additional forms or download additional electronic files when
submitting data for more than two fields.
Reporting of preliminary or estimated data is allowable, if necessary, to
meet the due date. You only have to file a revised report is required if
actual or corrected data vary more than plus or minus 4% from the data
previously reported.

SPECIFIC INSTRUCTIONS
PART 1: RESPONDENT IDENTIFICATION DATA

WHEN TO SUBMIT

Provide up-to-date company information.

You must file within 20 days after the last day of the report month. You
must file twelve reports per calendar year.

EIA ID number: Enter the 10-digit EIA ID number. Companies
operating in more than one State should note that a unique number has
been assigned for operations in each state. If we haven’t assigned an ID
number to you, leave the space blank and contact us at (877) 800-5261.

If additional fields are acquired, or storage activities begin in a
new facility during the year, you must enter their field characteristics
for the month when initial activity began.

HOW TO SUBMIT

Company name: Enter the company name.

Instructions on where to report via secure file transfer are below and
printed on Part 2 of Form EIA-191 and Form EIA-191L.
Secure File Transfer: You can file through the Secure File Transfer
System. The secure hypertext transfer protocol (HTTPS) is a secure,
encrypted method to send information electronically. All information is
protected by 128-bit encryption to maintain the privacy

PART 2: SUBMISSION INFORMATION
You can submit your completed Form EIA-191 via Secure File Transfer.
PART 3: FIELD CHARACTERISTICS
Report all volumes in thousand cubic feet (Mcf), 14.73 psia-60o F, as of
9:00 a.m., Central Standard Time (CST) on the last day of the report
month. Note that LNG storage facilities complete form EIA-191L, and
do not complete data items that are grayed out.
For Type of facility, check the appropriate box corresponding to one of
the following: depleted gas field, aquifer, or salt facility. Salt facilities
include both bedded and domal salt facilities. LNG facilities do not
complete this item on the EIA-191L.
For Field status, check the appropriate box for either active or inactive.
A facility is “inactive” if it has not had any injections for at least the
twelve months prior to this report month, and does not contain volumes
of working gas, or is in the process of abandonment or depletion. If
“inactive,” provide additional information in the comments section
about the circumstances.
PART 4: MONTHLY GAS STORAGE
You must provide information for your fields or facilities as
defined below in the Definitions. Report all volumes in thousand
cubic feet (Mcf), 14.73 psia-60o F, as of 9:00 a.m. CST on the
Page 1
last day of the report month.

In most cases, net injections or withdrawals should correspond to the
difference between total gas volume for the current and prior report
period. Include storage compressor use volumes with the injections and
withdrawals totals.
Comments: Use the comment space to describe any unusual or
substantially different aspects of your monthly operations that affect the
data you reported.

DEFINITIONS
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.
Injections: The volume of gas injected into storage facility or
reservoir during the report month.
Maximum Deliverability: The maximum rate (Mcf/day) natural
gas can be withdrawn (or delivered) from a storage facility when
filled to maximum capacity.
Total Gas in Storage: The sum of base gas plus working gas. For
LNG facilities, the total volume of liquefied natural gas held in
aboveground storage tanks.
Total Storage Field Capacity: The maximum volume of natural
gas (including base gas and working gas) that you can store in
an underground storage facility based on its design specifications,
the physical
characteristics
of
the
reservoir,
installed
compression equipment, and operating procedures particular to the site.
Withdrawals: The volume of gas withdrawn from storage
reservoirs or facilities during the report month.
Working (top storage) gas: The volume of natural gas in
an underground storage facility available to be withdrawn, not
including base gas. Working gas may or may not be completely
withdrawn during any particular withdrawal season.

SANCTIONS
Form EIA-191 is mandatory under 15 U.S.C. §772(b). Failure to
respond may result in a civil penalty of not more than $10,821 each day
for each violation. The government may bring a civil action to prohibit
reporting violations which may result in a temporary restraining order
or a preliminary or permanent injunction without bond. In such civil
action, the court may also issue mandatory injunctions commanding
any person to comply with these reporting requirements.

DISCLOSURE OF INFORMATION
Information collected in Parts 1, 2, and 3, as well as Base Gas data, on
Form EIA-191 is considered public information, and may be publicly
released in company or individually identifiable form. Information
collected in Part 4 (including Working Gas and Total Gas in Storage
data but excluding Base Gas), however, will be protected and will not
be disclosed to the public to the extent that it satisfies the criteria for
exemption under the Freedom of Information Act (FOIA), 5 U.S.C.
§552, the DOE regulations, 10 C.F.R. §1004.11, implementing the
FOIA, and the Trade Secrets Act, 18 U.S.C. §1905.
The Federal Energy Administration Act requires EIA to provide
company-specific data to other federal agencies when requested for
official use. The information you reported on this form may also be
made available, upon request, to another component of the Department
of Energy (DOE); to any Committee of Congress, the Government
Accountability Office, or other federal agencies authorized by law to
receive such information. A court of competent jurisdiction may obtain
this information in response to an order. The information may be used
for any nonstatistical purposes such as administrative, regulatory, law
enforcement, or adjudicatory purposes.
Disclosure limitation procedures do not apply to the statistical data
published from EIA-191 survey information. Some statistics may be
based on data from fewer than three respondents, or may be dominated
by data from one or two large respondents. In these cases, a
knowledgeable person may be able to closely estimate the information a
specific respondent reported.
