MONTHLY UNDERGROUND GAS STORAGE REPORT
FORM EIA-191
INSTRUCTIONS
PURPOSE

GENERAL INSTRUCTIONS

The Energy Information Administration (EIA) Form EIA-191,
“Monthly Underground Gas Storage Report,” provides data on the
operations of all active underground storage facilities. Data are
collected pursuant to the Federal Energy Administration (FEA) Act of
1974, Public Law 93-275. This report is mandatory under the FEA Act.
The data appear in the EIA publications Monthly Energy Review,
Natural Gas Annual, and Natural Gas Monthly.

All volumes should be reported in thousand cubic feet (Mcf). Negative
values should not be filed on any part of the Form EIA-191.
Provide data for all fields your company operates. You may copy
additional forms or download additional electronic files when
submitting data for more than 2 fields.

All companies that operate underground natural gas storage fields in
the United States must provide the information requested.

Reporting of preliminary or estimated data is encouraged if necessary
to meet the due date. Indicate when revised reports are submitted by
checking the box. A revised report is required if actual or corrected data
vary more than plus or minus 4 percent from the data previously
reported as estimated data.

WHEN TO REPORT

SPECIFIC INSTRUCTIONS

Information requested must be provided within 20 days after the end of
the report month. Twelve reports are required per calendar year.

PART 1: RESPONDENT IDENTIFICATION DATA

REPORTING REQUIREMENTS

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

PART 3: FIELD CHARACTERISTICS
All information requested in this part of the form must be reported each
time the form is submitted.
Information should be provided for your field/s as defined below in the

PART 4: MONTHLY GAS STORAGE DATA
All information requested in this part of the form must be reported each
time the form is submitted.
Information should be provided for your field/s 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. on the 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.
Comments: Use the space provided to describe any unusual or
substantially different aspects of your monthly operations that affect the
data 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 reservoirs during
the report month.
Maximum Deliverability: The maximum rate (Mcf/day) natural gas
can be withdrawn (or delivered) from a storage field when filled to
maximum capacity.
Total Gas in Storage: The sum of base gas plus working gas.
Total Storage Field Capacity: The maximum volume of natural gas
(including both base and working gas) that can be stored in an
underground storage facility in accordance with 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
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
The timely submission of Form EIA-191 by those required to report is
mandatory under Section 13(b) of the Federal Energy Administration
(FEA) Act of 1974, (Public Law 93-275), as amended. Failure to
respond may result in a civil penalty of not more than $2,750 a day for
each violation, or a fine of not more than $5,000 for each willful

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.

PROVISIONS FOR CONFIDENTIALITY
Information collected in Parts 1, 2, and 3 on Form EIA-191 will be
considered public information, and may be publicly released in
company or individually identifiable form, and will not be protected
from disclosure in identifiable form. Information collected in Part 4
(including Base Gas, Working Gas and Total Gas in Storage data),
however, will be protected and not 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 Energy Information Administration (EIA) will
protect your monthly gas storage information in accordance with its
confidentiality and security policies and procedures.
The Federal Energy Administration Act requires the EIA to provide
company-specific data to other Federal agencies when requested for
official use. The information 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 are not applied to the statistical data
published from EIA-191 survey information. Thus, there may be some
statistics that are based on data from fewer than three respondents, or
that are dominated by data from one or two large respondents. In these
cases, it may be possible for a knowledgeable person to estimate the
information reported by a specific respondent.

FILING FORMS WITH FEDERAL GOVERNMENT
AND ESTIMATED REPORTING BURDEN
Public reporting burden for this collection of information is estimated
to average 2.6 hours per response, including the time for reviewing
instructions, searching existing data sources, gathering and maintaining
the data needed, and completing and reviewing the collection of
information. Send comments regarding this burden estimate or any
other aspect of this collection of information, including suggestions for
reducing this burden, to the Energy Information Administration,
Office of Survey Development and Statistical Integration, EI-21,
1000 Independence Avenue, S.W., Washington, DC 20585; and to
the Office of Information and Regulatory Affairs, Office of
Management and Budget, Washington, DC 20503.
