### MONTHLY UNDERGROUND GAS STORAGE REPORT

FORM EIA-191

INSTRUCTIONS

PURPOSE

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

.



### REPORTING REQUIREMENTS

All companies that operate undergr ound natural gas storage fields in the United States must provi de the information requested.



### WHEN TO REPORT

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

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.

### Page 2 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-60 o 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 deliverab ility rates throughout the withdrawal season. Base gas usually is not withdr awn, 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Maximum Deliverability: The maximum rate (Mcf/day) natural gas can be withdrawn (or delivered) from a storage field when filled to maximum capacity.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 ga s 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 pr ocedures 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 th e 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.

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 FO IA, and the Trade Secrets Act, 18 U.S.C. §1905. The Energy Inform ation 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 info rmation 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 Federa l agencies authorized by law to receive such information. A court of competent jurisdiction may obtain this information in response to an or der.
