Frequently Asked Questions Concerning the

1998 MANUFACTURING ENERGY CONSUMPTION SURVEY (MECS)

Why have a MECS?

The Manufacturing Energy Consumption Survey (MECS)

collects data on energy consumption and usage patterns for the

manufacturing sector of the U.S. economy. The information

will be used to publish aggregate statistics on the following:

consumption of energy for fuel and nonfuel uses, energy

characteristics of establishments in the manufacturing sector,

energy consumption by end use, technologies currently in use

by U.S. manufacturers, energy prices, electricity generation

onsite, and participation in energy-management activities. This

information will be used by the U.S. Department of Energy

(DOE) to implement policy plans effectively.

What is a manufacturing establishment?

The reporting unit for the Manufacturing Energy Consumption

Survey (MECS) is the manufacturing establishment. A

manufacturing establishment is an economic unit at a single

physical location, for the mechanical or chemical transformation

of materials or substances into new products. 

An establishment is not necessarily identical to a business

concern or firm, either of which may consist of one or more

establishments. A company may consist of one or more

establishments that are engaged in separate or distinct activities. 

These establishments may be situated at one location and

separated physically as well as economically. 

Manufacturing operations are generally conducted in facilities

described as plants, factories, or mills, characteristically using

power-driven machines and materials-handling equipment. 

Manufacturing also includes such activities as the assembly of

components of manufactured products and the blending of

materials such as lubricating oil, plastics, resins, or liquors.

What should I report for?

If this establishment has previously completed the Annual

Survey of Manufacturers (ASM), Form MA-1000, conducted

by the U.S. Census Bureau, then the reporting boundaries for

the MECS should correspond to those used for the ASM. Each

reporting unit should be treated as a separate establishment

ONLY if that was the determination made for the ASM. Do not

consolidate ASM establishments for reporting on the MECS.

If this establishment has never completed an ASM, report for all

activities that occur at this physical location, in accordance with

the reporting boundaries as defined by the Census of

Manufactures (CM) and as reported in the 1997 CM.

What is NAICS?

For 1997 and subsequent reports, the North American Industry

Classification System (NAICS) will replace the Standard

Industrial Classification (SIC) system currently used by federal

statistical agencies. NAICS is unique in that its conceptual

framework is based on production processes. Therefore,

economic units that have similar production processes are

classified in the same industry. 

What is the reporting period?

The period covered by this report for most establishments is

calendar year 1998 (January 1 through December 31, 1998). 

The exception will be for those establishments whose

ownership or operation changed during 1998. Indicate the

reporting period covered in Section 1: Establishment

Information.

Do I have to fill out this questionnaire?

Yes. This survey is mandatory under the Federal Energy

Administration Act of 1974, Pub. Law No. 93-275, and under

Title 3, Subtitle B, of the Omnibus Budget Reconciliation Act

of 1986, Pub. Law No. 99-509, as amended by Title 1, Subtitle

G, of the Energy Policy Act of 1992, Pub. Law No. 102-486. 

Response is required by law from establishments included in the

MECS sample and receiving the MECS questionnaire. Failure

to respond may result in criminal fines, civil penalties, and other

sanctions as provided by law. 

Are these data confidential?

Yes. Under Section 9 of Title 13, U.S. Code, your report to the

Census Bureau is confidential. It may be seen only by sworn

Census Bureau employees and may be used only for statistical

purposes. The law also provides that copies retained in your

files are immune from legal process.

What if I have questions?

If you have any questions about what to report on this

questionnaire, please call the Census Bureau at 

1-800-528-3049.

How long will this questionnaire take?

Public reporting burden for this collection of information is

estimated to average nine hours per response, including the time

of 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, Statistics

and Methods Group, EI-70, Washington, D.C. 20585-0670; and

to the Office of Information and Regulatory Affairs, Office of

Management and Budget, Washington, D.C. 20503.

What if I need more time to complete the questionnaire?

The questionnaire should be returned no later than the due date

specified on the front. If you need additional time, please call

our processing office at 1-800-528-3049.

Instructions for Completing Form EIA-846C

General Instructions

1. Use the units specified on the questionnaire for reporting all

quantities. See page 4 for a list of Btu conversion factors. If

your establishment uses more precise conversion values for

your operations, use them, and indicate in Section 22:

Remarks, the conversion factor(s) used.

2. Do not consolidate establishments. The reporting

boundaries for your establishment should correspond to

those used in the Annual Survey of Manufactures and/or the

Census of Manufactures.

To resolve any consolidation problems, match the 11-digit

Census File Number (CFN), which is located on the MECS

questionnaire mailing label, with the CFN appearing on the

ASM mailing label. Responses to MECS questions should

include the same activities as those considered when

responding to the matching ASM. 

3. The energy sources (Sections 2 - 16) and end uses (Sections

17-18) sections of this questionnaire are designed so that all

questions associated with the particular energy source within

a section should be completed before going on to the next

energy source. Therefore, within these sections, the

questionnaire should be answered from the top of one

column to the bottom of the same column, before going on

to the next energy source (column).

4. Report dollar amounts rounded to the nearest dollar, e.g.,

report $1,257.59 as $1,258. 

5. If you do not maintain book records for particular items,

please use carefully prepared estimates.

6. Enter zeroes in the data columns if the value is zero or none.

7. Complete all applicable sections of the questionnaire.

8. The energy sources which are preprinted on the survey

questionnaire are considered the most frequently consumed,

but they do not represent a complete list of applicable energy

sources. If your establishment has energy sources that meet

the criteria for reporting, but are not preprinted on the

questionnaire, please specify those energy sources in

Section 16 and enter the data there. (See Reporting Criteria,

next column under Sections 2 through 16).

9. The following definitions for units are used throughout the

questionnaire:

Btu = British thermal unit(s)

One barrel = 42 gallons

One short ton = 2,000 pounds

Section 1: Establishment Information

In this section, indicate any changes in the establishment

ownership during 1998 and indicate the period covered by this

filing, whether the calendar year or other period.

Sections 2 through 16: Energy Sources (Fuels)

Reporting Criteria

An energy source should be reported on this questionnaire if:

1. the energy source was consumed as a fuel, (that is, for

heat, power, or electricity generation) or

2. the energy source was consumed as a nonfuel (feedstock,

raw material input), or

3. the energy source was shipped offsite from this

establishment site.

Data are collected for the following energy sources (fuels):

Section 2: Electricity

Section 3: Steam and Industrial Hot Water

Section 4: Natural Gas

Section 5: Butane, Ethane, and Propane

Section 6: Mixtures of Ethane, Butane, and Propane and

Other LPG and NGL

 Section 7: Acetylene, Hydrogen, and Waste and

Byproduct Gases

Section 8: Diesel Fuel, Distillate Fuel Oil and Residual

Fuel Oil

Section 9: Kerosene and Motor Gasoline

Section 10: Coal (Anthracite, Bituminous & Subbituminous,

and Lignite)

Section 11: Breeze and Coal Coke

Section 12: Petroleum Cokes (Fluid Catalytic Cracking Unit

Coke, Marketable Petroleum Coke, both

unrefined and calcined)

Section 13: Blast Furnace Gas and Coke Oven Gas

Section 14: Agricultural Waste, Pulping or Black Liquor,

and Waste Oils and Tars

Section 15: Wood (Directly from Trees, Residues and

Byproducts and Wood/Paper-related Refuse) 

Section 16: Other Energy Sources

NOTE - In making additional entries, the preprinted entry

“Waste and Byproduct Gases” (Section 7, column 3) includes

all waste gas streams (for example, refinery gas, fuel gas, vent

gas, plant gas, off gas, still gas, and other waste gases) produced

onsite, except hydrogen.
Page 3 Form EIA-846C (1999)

Instructions for Completing Form EIA-846C, cont.

Energy Sources, cont.

To reduce the reporting burden and eliminate unnecessary

correspondence, special instructions have been developed for

the reporting of byproduct (or product) energy sources. If your

only means of supply of an energy source during 1998 was as a

byproduct (or product) of an energy source used as a feedstock

(or raw material input) to any of your manufacturing processes,

that byproduct energy source should be reported only if it was

at least partially consumed onsite as a fuel. If the byproduct 

(or product) energy source was not consumed as a fuel, it

should be excluded.

Energy Sources Reporting Examples

Example 1 - Your establishment depended entirely on

electricity for heat and power, no combustible energy sources

were consumed. In this instance, complete Section 2:

Electricity. No data should be entered in Sections 3 through 16. 

Go to Section 17 and complete the remainder of the

questionnaire.

Example 2 - Bituminuous coal is received onsite and converted

into coke which is then shipped offsite. Complete Section 10,

column 2 for the coal. Complete Section 11, column 2 for the

coal coke. Report the quantity of bituminous coal consumed as

a feedstock in question 104, report the quantity of coke

produced onsite in question 111, check the “Yes” box in

question 112, and report the quantity of coke shipped offsite in

question 115.

Example 3 - Butane is used as a feedstock to produce butylene

onsite. The butylene is then used as a feedstock to produce

butadiene which is shipped offsite. Report the butane used as a

feedstock in Section 5, column 1, question 53 because it is not

used as a fuel or shipped offsite. Butadiene would not be

reported in question 54, because it is not an identified energy

source.

Sections 17 and 18: 

Estimated End-Use Percent Consumption

These sections of the questionnaire are intended to provide

information on the purposes for which various energy sources

are used in the manufacturing sector.

Section 17 covers Electricity, Total Natural Gas and Total Coal.

Section 18 covers Total LPG and NGL, Total Diesel Fuel and

Distillate Fuel Oil, and Residual Fuel Oil.

See specific instructions for completing these sections at the

beginning of each section. 

End-Use Reporting Examples

Example 4 - If coal is consumed in boilers to generate steam,

some of which is passed through an extractor/condensing

turbine generator, all coal consumption would be reported in

question 166, column 3 (Indirect Uses - Boilers).

Example 5 - If an establishment can distinguish energy used for

emissions controls, it should be reported in either question 177

or 193 (Other direct nonprocess use), depending on the energy

source used.

Section 19: Energy-Management Activities

In this section, indicate whether your establishment participated

in the listed energy-management activities during 1998, and for

selected activities, indicate the amount of the energymanagement activity costs paid for by the establishment.

Section 20: Technologies

Indicate any of the technologies present in this establishment. 

Listed technologies include general technologies which may be

found in any manufacturing establishment, technologies related

to cogeneration, and specific technologies for particular NAICS

codes. 

Section 21: Establishment Size

This section asks for the number of buildings and total square

footage associated with this establishment. See the specific

instructions in this section for the definition of what should be

counted as a building.

Section 22: Remarks

Please provide any explanations that may be helpful to us in

understanding your reported data. Indicate any Btu conversion

factors used, if different from those provided on page 4. If

additional space is needed, attach a separate sheet, including the

11-digit Census File Number (CFN) located on the mailing label
