After being approved by the OMB in 1999, the Form EIA-176 was revised to: (1) change
the filing date from April 1 following the end of the report year to March 1 following
the end of the report year, (2) remove the requirement to distinguish between firm and
interruptible deliveries to consumers; and (3) remove the requirement to distinguish
between gas volumes delivered to commercial and industrial consumers having nonutility
generation of electricity from those not generating electricity.
Data reported on this form are no longer considered proprietary. Response to the
form continues to be mandatory.
Survey Universe and Response Statistics
The Form EIA-176 is required from all identified interstate and intrastate natural
gas pipeline companies, investor and municipally owned natural gas distributors,
underground natural gas storage operators, synthetic natural gas plant operators, and
field, well, or processing plant operators that deliver natural gas directly to
consumers (including their own industrial facilities) and/or that transport gas to,
across, or from a state border through field or gathering facilities.
Each company and its parent company or subsidiaries were required to file if they met
the survey specifications. The original list totaled 1,831 questionnaire packages.
To this original list, 37 names were added and 35 were deleted as a result of the
survey processing. Additions were the result of comparisons of the list to other
survey lists. Deletions resulted from post office returns and determinations that
companies were out of business, sold, or not within the scope of the survey. After
all updates, 1,793 responses were entered into the data base from approximately 1,400
companies. There were 40 nonrespondents.
Summary of Form EIA-176 Data Reporting Requirements
The EIA-176 is a multi-line schedule for reporting all supplies of natural gas and
supplemental gaseous fuels and their disposition within the state indicated.
Respondents file completed forms with EIA in Washington, DC. Data for the report
year were due by March 1st. Extensions of the filing deadline for up to 30 days were
granted to any respondent upon request.
All natural gas and supplemental gaseous fuels volumes are reported on a physical
custody basis in thousand cubic feet (Mcf), and dollar values are reported to the
nearest whole dollar. All volumes are reported at 14.73 pounds per square inch
absolute pressure (psia) and 60 degrees Fahrenheit.
Routine Form EIA-176 Edit Checks
A series of manual and computerized edit checks are used to screen the Form EIA-176.
The edits performed include validity, arithmetic, and analytical checks.
The incoming forms are reviewed prior to keying. This prescan determines if the
respondent identification (ID) number and the company name and address are correct,
if the data on the form appear complete and reasonable, and if the certifying
information is complete.
Manual checks on the data are also made. Each form is prescanned to determine that
data were reported on the correct lines. The flow of gas through interstate pipelines
is checked at the company level to ensure that each delivery from a state is matched
with a corresponding receipt in an adjoining state
After the data are keyed, computer edit procedures are performed. Edit programs
verify the report year, state code, and arithmetic totals. Further tests are made to
ensure that all necessary data elements are present and that the data are reasonable
and internally consistent. The computerized edit system produces error listings with
messages for each failed edit test. When problems occur, respondents are contacted by
telephone and required to file amended forms with corrected data.
Comparison of the Form EIA-176 with Other Data Sources
Comparison of the EIA-176 data with data from similar series is another method of
ensuring the validity of the data published in this report. This comparison on a
company-by-company basis showed significant differences that respondents were required
The FPC-14, "Annual Report for Importers and Exporters of Natural Gas," was discontinued in
September 1995. Data on imports and exports of natural gas, as collected by the EIA-176 survey,
were checked by comparing individual responses with quarterly data reports, Natural Gas Imports
and Exports, filed with the Office of Fossil Energy, U.S. Department of Energy. These
quarterly reports are required as a condition of import/export authorizations. Where
discrepancies were noted, respondents were required to file corrected reports.
Similarly, data on the underground storage of natural gas were compared with submissions
of Form EIA-191, "Monthly Underground Gas Storage Report." If
significant differences were noted, companies were contacted to reconcile the
discrepancies. During 2000, the 117 companies filing the Form EIA-191
reported total injections of 2,680 billion cubic feet and total withdrawals of 3,482
billion cubic feet. This compares to 2,684 billion cubic feet of injections and 3,498
billion cubic feet of withdrawals, as reported on the Form EIA-176.
Data on deliveries to residential, commercial, and industrial consumers were compared
with data submitted on Form EIA-857, "Monthly Report of Natural
Gas Purchases and Deliveries to Consumers." Where discrepancies were noted, respondents
were required to file corrected reports for either and sometimes both surveys. Numerous
telephone calls were made to clarify any misunderstandings concerning the correct
filing of both forms. Typical errors included electric utility volumes combined with
industrial volumes, sale for resale volumes reported as industrial consumption,
cogeneration volumes not reported on Form EIA-857, and
misinterpretation of general instructions.
A discussion of the comparison of the data on deliveries to electric utilities filed on
Form EIA-176 and that reported in the EIA publication,
Electric Power Annual,
is included under "Electric Utility Data."
Form EIA-895, "Monthly Quantity and Value of Natural Gas Report"
Form & Instructions
Beginning with 1980 data, natural gas production data previously obtained on an
informal basis from the appropriate state agencies were collected on the Form EIA-627,
"Annual Quantity and Value of Natural Gas Report." This form was designed by the EIA
to collect annual natural gas production data from the appropriate state agencies
under a standard data reporting system within the limits imposed by the diversity of
data collection systems of the various producing states. It was also designed to avoid
duplication of the efforts involved in the collection of production and value data by
producing states and to avoid an unnecessary respondent burden on gas and oil well
operators. In 1993, value and associated volume of marketed production by month were
added to the EIA-627. In 1996, the Form EIA-627 was discontinued. The information is
collected on an annual schedule on the Form EIA
In 1993, the Office of Management and Budget approved the Form EIA-627 for use in
report years 1994 through 1996. In 1994, the Interstate Oil and Gas Compact Commission
decided to discontinue collection of their form, "Monthly Report of Natural Gas
Production." Data collection on the Form EIA-895 began in January 1995. All gas
producing states are requested to report on the Form EIA-895; a voluntary report.
In 1996, an annual schedule was added to the voluntary Form EIA-895 to replace the
Form EIA-627. Data are reported by state agencies. The form was designed to provide
a standard reporting system, to the extent possible, for the natural gas data reported
by the states. Data are not considered proprietary.
Survey Universe and Response Statistics
Form EIA-895 is mailed to energy or conservation agencies in all 33 natural gas
producing states. All producing states participate voluntarily in the EIA-895
survey by filing the completed form or by responding to telephone contacts.
Reports on state production are due 20 days after the end of the report month.
In most cases, the data are not available to the states until after this time period.
Therefore, states are requested to send the report within 80 days after the end of the
report month. The annual schedule of the Form EIA-895 is due with the December data
Of the 33 natural gas producing states, all participated in the voluntary EIA-895 survey
by filing the completed form or by responding to telephone contacts. Data on the
quantities of nonhydrocarbon gases removed in 2000 were reported by the appropriate
agencies of 11 of the 32 producing states. These 11 states accounted for 46 percent
of total 2000 gross withdrawals. The State of Missouri reported zero gross withdrawals.
The commercial recovery of methane from coalbeds contribute a significant amount to the
production totals in a number of states. Coalbed methane seams production quantities
(in million cubic feet) are included in gross withdrawals totals for the following
states: Alabama (112,393), Colorado (413,290), New Mexico (583,581), and Wyoming
Summary of Data Reporting Requirements
The Form EIA-895 is a two-page form divided into five parts. Part I requests
identifying information including the name and location of the responding state agency
and the name and telephone number of a contact person within the agency. Part II
collects monthly data on the production of natural gas including gross withdrawals from
both gas and oil wells; volumes returned to formation for repressuring, pressure
maintenance, and cycling; quantities vented and flared; quantities of nonhydrocarbon
gases removed; quantities of fuel used on lease; and marketed production. Part III of
the form is for reporting the monthly volume and value of marketed production. Part IV
of the form is the annual schedule which collects data on the number of producing gas
wells, the production of natural gas including gross withdrawals from both gas and oil
wells; volumes returned to formation for repressuring, pressure maintenance, and cycling;
quantities vented and flared; quantities of nonhydrocarbon gases removed; quantities of
fuel used on lease; marketed production; the value of marketed production; and quantity
of marketed production (value based). Part V is space to be used by the respondent to
explain data elements reported that may be based on definitions differing from those
applied to data in previous years.
Respondents are asked to report all volumes in thousand cubic feet at the state's
standard pressure base and at 60 degrees Fahrenheit. All dollar values are reported
Routine Form EIA-895 Edit Checks
Each filing of Form EIA-895 is manually checked for reasonableness and mathematical
accuracy. Information on the forms is compared to totals of monthly data reported.
Volumes are converted, as necessary, to a standard 14.73 psia pressure base.
Reasonableness of data is assessed by comparing reported data to the previous year's
data. State agencies are contacted by telephone to correct errors. Amended filings or
resubmissions are not a requirement, since participation in the survey is voluntary.
Comparison of the Form EIA-895 with Other Data Sources
Annual production data, as reported on the Form EIA-895, are compared to the sum of
monthly data previously reported on the Monthly Schedule. The comparison is made in
order to assure the reasonableness of the data reported on the Form EIA-895, Annual
Schedule. Any significant differences are resolved by contacting the reporting state.
For discussion of the comparison of production data collected on Form EIA-895 and
that collected on Form EIA-23, "Annual Survey of Domestic Oil and Gas Reserves,"
see the EIA report, U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves.
Form EIA-191, "Underground Natural Gas Storage Report"
Form & Instructions
The Form EIA-191, "Monthly Underground Natural Gas Storage Report," was revised
effective January 1994. Among the changes from the form used from 1991 through 1993
is a distinction between a monthly and annual survey. Prior to 1991, data on the
storage of natural gas were collected on a survey jointly implemented in 1975 by the
Federal Power Commission (FPC), the Federal Energy Administration (FEA), and the Bureau
of Mines (BOM) as the FPC-8/ FEA-G-318 system. The data received on both the FPC-8 and
FEA-G-318 were computerized and aggregated by FPC. The form was previously revised in
1991 to include storage data by state, field, and reservoir.
At the beginning of 1979, the EIA assumed responsibility for the collection, processing,
and publication of the data gathered in the survey. Form FEA-G-318 was renewed on
July 1, 1979, as Form EIA-191 and the survey was retitled the FPC-8/EIA-191 Survey.
Form FPC-8 was renewed in December 1985 and the survey retitled FERC-8/EIA-191 Survey.
The forms were not merged because of FERC's stated desire to maintain the separate
identity of the FERC-8 for administrative reasons. In September 1995, the FERC
discontinued the reporting requirements of Form FERC-8. FERC jurisdictional firms
continue to file Form EIA
Survey Universe and Response Statistics
The 140 companies that operate underground facilities file the Form EIA-191
The response rate as of the filing deadline is approximately 20 percent. Data from the
remaining 80 percent of respondents are received in writing and/or by telephone within
3 to 4 days after the filing deadline. All data supplied by telephone are subsequently
filed in writing, generally within 15 days of the filing deadline. The final response
rate is 100 percent.
Summary of EIA-191 Data Reporting Requirements
The EIA-191 monthly schedule contains current month and prior month's data on the
total quantities of gas in storage, injections and withdrawals, the location
(including state and county, field, reservoir) and peak day withdrawals during the
reporting period. Prior month's data are required only when data are revised. The
annual schedule contains type of facility, storage field capacity, maximum
deliverability and pipelines to which each field is connected. The annual schedule
is filed with the December submission.
Collection of the survey is on a custody basis. Information requested must be provided
within 20 days after the first day of each month. Twelve reports are required per
calendar year. Respondents are required to indicate whether the data reported are actual
or estimated. For most of the estimated filings, the actual data or necessary revisions
are reflected in the prior month section of the monthly form. Actual data on natural
gas injections and withdrawals from underground storage are based on metered quantities.
Data on quantities of gas in storage and on storage capacity represent, in part,
reservoir engineering evaluations. All volumes are reported at 14.73 psia and 60
Routine Form EIA-191 Edit Checks
Data received on Form EIA-191 are entered into the survey processing system. The
survey's five principal data elements (total, base, working gas in storage, injections,
and withdrawals) receive a preliminary visual edit to eliminate and correct obvious
errors or omissions. Respondents are required to refile reports containing any
inconsistencies or errors.
"Quarterly Natural Gas Import and Export Sales and Price Report"
The collection of data covering natural gas imports and exports was begun in 1973 by the
Federal Power Commission (FPC). On October 1977, FPC ceased to exist and its data collection
functions were transferred to the Federal Energy Regulatory Commission (FERC) within the
Department of Energy (DOE). From 1979 to 1994, the Energy Information Administration (EIA)
had the responsibility for collecting Form FPC-14, "Annual Report for Importers and Exporters
of Natural Gas." Data are not considered proprietary. The Form FPC-14 was discontinued in 1995.
Beginning in 1995, import and export data are taken from the "Quarterly Natural Gas Import
and Export Sales and Price Report." This report is prepared by the Office of Fossil
Energy, U.S. Department of Energy, based on information submitted by all firms having
authorization to import or export natural gas.
Survey Universe and Response Statistics
All companies are required, as a condition of their authorizations to import or export
natural gas, to file quarterly reports with the Office of Fossil Energy. These data are
collected as part of its regulatory responsibilities. The data are reported at a
monthly level of detail.
Routine Edit Checks
Respondents are required to certify the accuracy of all data reported. The data
are checked for reasonableness and accuracy. If errors are found, the companies
are required to file corrected data. The data are compared with data reported by
the National Energy Board of Canada and are published quarterly. All natural gas
volumes in this report are expressed at a pressure base of 14.73 pounds per square
inch absolute and temperature of 60 degrees Fahrenheit, except as noted. All import
and export prices are in U.S. dollars and, except for liquefied natural gas (LNG)
exports, are those paid at the U.S. border. LNG export prices are those paid at
the point of sale and delivery in Yokohama, Japan.
Form EIA-857, "Monthly Report of Natural Gas Purchases and Deliveries to Consumers"
Form & Instructions
The original Form EIA-857 was approved for use in December 1984. Response to the
Form EIA-857 is mandatory on a monthly basis. Data collected on the
Form EIA-857 cover the 50 states and the District of Columbia and include both price
and volume data. Data are considered proprietary.
Survey Universe and Response Statistics
A sample of approximately 400 natural gas companies, including interstate pipelines,
intrastate pipelines, and local distribution companies, report to the survey.
The sample was selected independently for each of the 50 states and the District of
Columbia from a frame consisting of all respondents to Form EIA-176
who reported deliveries of natural gas to consumers in the residential, commercial,
or industrial sectors. Each selected company is required to complete and file the
Form EIA-857 on a monthly basis. Initial response statistics on a monthly basis
are as follows: responses received by due date, approximately 50 percent, and responses
received after follow-up, 95 percent. When a response is extremely late, and the
company represents less than 25 percent of the natural gas volumes delivered by all
sampled companies in the state, values are imputed as described in Statistical Details.
When the company's submission is eventually received, the submitted data are used for
future processing and revisions.
The Form EIA-857 is a monthly sample survey of firms delivering natural gas to consumers.
It provides data that are used to estimate monthly sales of natural gas
(volume and price) by state and monthly deliveries of natural gas on behalf of others
(volume) by state to three consumer sectors - residential, commercial, and industrial.
(Monthly deliveries and prices of natural gas to electric utilities are reported on
the Form FERC-423, "Monthly Cost and Quality of Fuels for Electric Plants Report," and
the Form EIA-906, "Power Plant Report.") See Statistical Details for a discussion of the
sample design and estimation procedures.
Summary of Form EIA-857 Data Reporting Requirements
Data collected monthly on the Form EIA-857 on a state level include the volume and
cost of purchased gas, the volume and cost of natural gas consumed by sector
(residential, commercial, and industrial), and the average heat content of all
gas consumed. Respondents file completed forms with EIA in Washington, DC on or
before the 30th day after the end of the report month.
All natural gas volumes are reported in thousand cubic feet at 14.73 psia at 60 degrees
Fahrenheit and dollar values are reported as whole dollar.
Routine Form EIA-857 Edit Checks
A series of manual and computerized edit checks are used to screen the Form EIA-857
The edits performed include validity and analytical checks.
Electric Utility Data
The electric utility data published in this report are taken from the
"Power Plant Report" and
FERC-423, "Monthly Cost and Quality of Fuels for Electric Plants Report."
These data were used in order to maintain consistency among EIA publications.
Electric data are necessary on the Form EIA-176 to provide a
supply/disposition balance on the form. Differences in the two surveys are apparent in the
results published in "Natural Gas Deliveries to Consumers by State," and "Natural Gas
Delivered to Electric Utilities for the Account of Others by State," where volumes in
the latter sometimes exceed volumes in the former. A state-by-state comparison of the
reported volumes of natural gas, as collected on the Form EIA-176
and EIA-906 is shown in
The national totals differ by 401 billion cubic feet or 15 percent in relative terms.
While processing the data reported on the Form EIA-176, the EIA
made special efforts to determine the reasons for the differences in reporting of
electric utility data on the Form EIA-176 and Form EIA-906.
Typical instances of misreporting occurred in the reporting of gas delivered to electric
utilities for the account of others. Some companies reported these deliveries under
sales for resale. Others reported them under transportation, exchange and/or storage
deliveries. A few others reported them under transported to industrials.
Companies making mistakes were asked to refile, and new companies were asked to file
when they were found making deliveries of gas. Most companies were cooperative, and
their refilings and new filings improved the accuracy of the data.
Other Data Sources
The U.S. Minerals Management Service (USMMS) supplied data on the quantity and value of
natural gas production and the number of producing wells in the Gulf of Mexico Outer
Continental Shelf. Volumes of extraction losses were reported on
"Annual Report of the Origin of Natural Gas Liquids Production." Heat (Btu) content
extraction loss was estimated from data reported on
and Form EIA-816,
"Monthly Natural Gas Liquids Report." Volumes and prices of natural gas imports and exports
were reported to the Office of Fossil Energy, U.S. Department of Energy, Natural Gas Imports
and Exports. These data are nonproprietary and are filed annually by each individual or
organization having authorization to import and export natural gas.
