General Information and Instructions
Why This Questionnaire?
The U.S. Environmental Protection Agency (EPA) is currently developing regulations to be processed
under Section 316(b) of the Clean Water Act, 33 U.S.C. Section 1326(b). Section 316(b) provides that any
standard established pursuant to Sections 301 or 306 of the Clean Water Act (CWA) and applicable to a
point source requires that the location, design, construction, and capacity of cooling water intake
structures reflect the best technology available (BTA) for minimizing adverse environmental impact.
Answers to the enclosed technical questionnaire will help EPA better understand the design and operation
of cooling water intake structures at industrial facilities that are subject to Section 3 16(b).
Data from this detailed questionnaire are not intended to identify whether a specific facility’s cooling water
intake structures are having an adverse environmental impact. Moreover, questionnaire responses are not
intended to identify whether a specific facility is employing BTA with respect to minimizing adverse
environmental impacts from cooling water intake structures, though they may help EPA determine BTA
options for various classes of facilities. The questionnaires are simply tools for characterizing some of the
following: type and nature of facilities using cooling water, specific uses of cooling water, design and
configuration of cooling water systems and cooling water intake structures, types of technologies being
used at intake structures, and whether facilities have previously evaluated the environmental impacts of
their cooling water intake structures. Data from the questionnaires will be factored into ongoing research
being conducted by EPA that is more specifically designed to determine the nature of adverse impacts and
the types of control technologies that might minimize such impacts. All of EPA’s research efforts will feed
the development of regulatory options, some of which will subsequently be fashioned into a proposed
rulemaking that will be put forth for public review and comment.
Please note that it is not the intent of EPA to require facility personnel to go to unusual lengths to retrieve
information to respond to this questionnaire. Responses should be based on data that can be accessed from
plant records with reasonable diligence.
The enclosed plant-level questionnaire consists of three parts. Part 1 requests general plant information,
such as plant name, location, operating status, Standard Industrial Classification (SIC) codes, and
National Pollutant Discharge Elimination System (NPDES) permit status. In addition, this part screens
plants from the survey that may not use cooling water for contact or noncontact cooling purposes or are
not directly withdrawing cooling water from surface water and, thus, are not subject to Section 316(b).
Part 2 requests plant-level technical data. Section A requests profile information on the plant’s cooling
water systems, cooling water intake structures, cooling water discharge ou fails, and the plant’s water
balance diagram. Section A first requests basic design and operational data for each of the plant’s cooling
water systems that are presently operating, temporarily offline, or planned or under construction.
General profile data are then requested for the plant’s intake structures that directly withdraw cooling water
from surface water. The type of data requested for the cooling water structures includes the following:
Detailed Industry Questionnaire: Phase I I Cooling Water Intake Structures—Traditional Steam Electric Utilities iii
-------
plant-designated names and numbers, latitudes and longitudes, total design intake flows, proportion of
total flows used for cooling, and activities for which cooling water was used in 1998. Section A requests
some very basic data on cooling water discharge outfalls, such as plant-designated names or numbers and
latitudes and longitudes at the point of each discharge outfall. The information from this section will be
related to other data requested throughout the questionnaire to give EPA an understanding of the plant’s
general design and use of cooling water. Finally, a water balance diagram is requested to provide EPA
with an understanding of how cooling water use and discharge practices relate to the plant’s general water
use practices. The diagrams will be used to analyze other data requested throughout the survey.
Section B requests information on the type of surface water sources being used by plants to provide cooling
water. The configuration of the plant’s intake structures is requested, such as whether intake canals!
channels are used, whether the intake structure incorporates abay or cove, and whether the intake structure
is at the shoreline or offshore. Depth of the water source at the withdrawal point is requested in addition
to the average distance of the intake structure below the water surface. The section concludes by
requesting information on whether sensitive aquatic ecological areas are within an area that is influenced
by the plant’s intake structures, if such information is known. The data from this section of the
questionnaire will enable EPA to characterize the distribution of plants that have cooling water intake
structures and the types of water bodies from which cooling water is being withdrawn.
Section C requests basic design and operating data about the technologies being used at cooling water
intake structures. The questions are limited to those intake structures that directly withdraw cooling water
from surface water. Information is also solicited on the design pass-through velocity at each intake
structure. Actual monthly cooling water intake flows are also requested for each intake structure for the
years 1996 to 1998. In addition, plants are asked to provide some basic data if they have ever reduced
cooling water intake flow rates to minimize impingement and/or entrainment and if they have employed
dilution pump technologies to reduce the temperature of their discharge. For plants employing an ice
control system at any of their cooling water intake structures, some basic information regarding the type
of system(s) in place is requested. Some basic information on technologies that were previously used to
minimize impingement and/or entrainment at an intake structure but were ineffective is requested. Finally,
some very basic data on cooling water towers are requested for those plants that employ such devices.
Section D of the questionnaire requests information on the types of studies that may have been conducted
at the plant. Basic data are requested for any Section 316(b) demonstration studies that may have been
completed (i.e., studies to show that the location, design, construction, and capacity of a cooling water
intake structure reflect BTA for minimizing adverse environmental impact). Information is also requested
on any discrete biological or technology-related studies that have been conducted by the plant on
impingement and entrainment. Through this section of the questionnaire, EPA is attempting to identify
research that plants have already undertaken on Section 31 6(b)-related topics and the availability of study
data.
Section E requests some basic information for cooling water intake structures planned or under
construction. Basic design data are requested for these intake structures. This information will help EPA
gain an understanding of the numbers of new intake structures expected to go on line in the future and their
basic design and operating characteristics.
IV Detailed Industry Questionnaire: Phase II Cooling Water Intake Structures—Traditional Steam Electric Utilities
-------
General Information and Instructions
Part 3 of the survey asks for economic and financial information about plants and steam-electric
generating units. The EPA will use this information to assess the potential impacts of compliance with
cooling water intake structure guidelines (under the authority of Section 316(b) of the Clean Water Act)
on the economic viability of all affected plants and their steam-electric generating units.
Specifically, EPA needs to determine how many plants and generating units are likely to experience
adverse economic impacts as a result of compliance with regulation, how large the economic impacts will
be, and if these impacts will be more severe for plants and generating units owned by small firms than
those owned by non-small firms. In order to evaluate the full economic impact of the regulation, EPA will
consider the costs associated with performing Section 316(b) studies, additions to cooling water intake
equipment, operating and maintenance costs associated with the regulation, and any impacts of Section
316(b) compliance requirements on the plant’s economic efficiency. EPA will estimate compliance cost
impacts on utility and plant cash flows and assess the likelihood of full or partial plant closures as a result
of the regulation. EPA needs the information requested in this part of the survey in order to conduct these
analyses.
The economic and financial portion of the questionnaire requests information about each plant as well as
its steam-electric generating units. Frequently, your accountant or comptroller is the best source of this
kind information. You may need to contact your utility headquarters for some of the information
requested.
Authority
EPA is given authority to administer the technical questionnaire under Section 308 of the CWA (33 U.S.C.
Section 1318). Late filing of the questionnaire, or failure to follow any related EPA instructions, may
result in civil penalties, criminal fines, or other sanctions provided by law.
Who Must Complete This Questionnaire?
This questionnaire has been designed for completion by traditional steam electric utilities that are point
sources as defined under Section 502 of the Clean Water Act (33 U.S.C. Section 1362).
Beyond this technical questionnaire, other editions have been produced for (1) steam electric nonutility
power producers and (2) other manufacturers that use cooling water. The other manufacturers to receive
a detailed questionnaire will include facilities from the following four major manufacturing sectors: Paper
and Allied Products (SIC 26), Chemical and Allied Products (SIC 28), Petroleum and Coal Products (SIC
29), and Primary Metals (SIC 33). Each of these groups has been identified by EPA as using large
quantities of cooling water and, therefore, potentially subject to Section 316(b) requirements.

General Information and Instructions
Once the surveys have been submitted, they will be entered into an EPA database and quality assurance
reviews will be performed. During this time, your facility may be called by one of EPA’s contractors to
verify your data.
Confidential Business Information
You may assert a business confidentiality claim for some or all of your responses to the technical
questionnaire, as described in 40 CFR 2.203(b) (see full text below). Complete regulations governing
confidentiality of business information (CBJ) appear in 40 CFR, Part 2, Subpart B.
40 CFR 2.203(b) Method and time of asserting business confidentiality claim. A business which is submitting
information to EPA may assert a business confidentiality claim covering the information by placing on (or attaching
to) the information, at the time it is submitted to EPA, a cover sheet, stamped or typed legend, or other suitable form
of notice employing language such as ‘trade secret,’ ‘proprietary,’ or ‘company confidential.’ Allegedly confidential
portions of otherwise nonconfidential documents should be clearly identified by the business, and may be submitted
separately to facilitate identification and handling by EPA. If the business desires confidential treatment only until
a certain date or until the occurrence of a certain event, the notice should so state.
You may claim confidentiality of business information for any of your responses by checking (I’) the
circle at the bottom of the page orby a method described above. Alternatively, all eligible questions in this
questionnaire may be globally claimed confidential by checking the circle at the end of this paragraph.
Note, however, that certain types of information cannot be claimed as confidential under the CWA (e.g.,
plant location, water body, water flow data, water body type). Questions that cannot be claimed as
confidential do not include an individual check-off circle at the bottom of the page. If no check mark
appears on this page or on the bottom of other pages and no other claim of confidentiality has been made
with respect to any of your given responses, EPA may make the data available to the public without further
notice. Please note that you may be required to justify any claim of confidentiality at a later time.
All eligible data are CBI 0
If EPA must reveal information covered by a claim of confidentiality, the Agency will strictly follow the
requirements and procedures set forth in 40 CFR Part 2, Subpart B. Overall, EPA may reveal submitted
information protected by a CBI claim only to other employees, officers, or authorized representatives of
the United States who are responsible for implementation of the Clean Water Act. EPA has extensive
standard operating procedures in place to handle, store, and transmit CBI data and has a long history of
successfully managing this type of information. In addition, personnel expected to handle CBI data are
required by the Agency to be trained and certified.
EPA may make information covered by a claim of confidentiality available Agency contractors so that
work can be performed under their contracts. All EPA contracts require that contractor employees must
use CBI data only to do work specified by EPA. The information will not be shown to anyone, other than
EPA officials, without first having received written approval from the affected business or from EPA’s
legal office. If you have any comments on this matter, please include them with your completed
questionnaire.

1. Please provide the general profile data and design types requested in the matrix below for each of the
plant’s cooling water systems that are presently operating, or temporarily offline. Do not include
cooling water systems planned, under construction or permanently offline.
NOTES: Please consider your plan: as having only one cooling water system, unless your plant has systems that are
physically separated (i.e., have separate water intake and outlet structures) and can be operated independently. If your
plant has several intake structures, but only one outlet structure, or vice-versa, please consider the plant as having only
one cooling water system. Intake structures with multiple bays count as one intake structure.
Information on structures planned or under construction is requested in Section E.
DEFINITION
For the purposes of this questionnaire, a cooling water system is a system that provides water to/from
a plant to transfer heat from equipment or processes therein. A system includes, but is not limited to,
one or more water intake and outlet structures, cooling towers, ponds, pumps, pipes, and canals/channels. For plants
that use surface water for cooling, a cooling water system begins at the first barner(s) to ingress and/or egress by fish
and other aquatic wildlife (e.g., at the wefr wall, at the trash rack, etc.) and ends at the discharge outlet(s).

Cooling Water Intake Structures
2. How many intake structures does the plant have that directly withdraw surface water to support, at
least in part, contact or noncontact cooling operations within the plant?
Consider only those intake structures presently operating and temporarily offline (i.e., expected to
operate again in the future). Do not include intake structures planned or under
construction or permanently offline
DEFINITION
For the purposes of this questionnaire, a cooling water intake structure is the total structure used to
wfthd raw water from a water source up to the first intake pump or series of pumps. The intended use
of the cooling water is to absorb waste heat rejected from processes employed or from auxiliary operations on the plant’s
premises. Single cooling water intake structures may have multiple intake bays and could serve more than one generating
unit. If a plant has intake structures that withdraw water for purposes besides cooling, the entire intake structure should
be considered a cooling water intake structure under the questionnaire.

For the purposes of this questionnaire, a zero-discharge
plant is a plant that does not return any treated or
untreated plant effluent (excluding storm water) to surface water, a P01W,
a privately-owned treatment works, or a groundwater injection well. An
example of a zero-discharge plant might be an entity that discharges its total
effluent to an evaporative pond or that completely recycles its wastewater.

Flow Distribution/Water Balance Diagram
9. Please attach a flow distribution/water balance diagram to this section of the questionnaire. The
flow diagram should contain the information itemized below.
NOTE: If you have an existing diagram, perhaps as part of your NPDES permit application package, you may
modify it to include the information reques:ecL If you do not have a flow diagram, please develop one. The diagram
can be printed or typed. A sample diagram has been included at the end of this section to clarify the type of
information being requested.
(a) Intake-Related Data (based on 1998 flow data)
(1) By intake structure (both cooling water intake structures as well as others), note
contributing sources of new water to the plant by generic name (e.g., groundwater, surface
water, local water supplier, or water supply of plant other than your own) despite how
that water is ultimately used.
• Include intake structures presently operating, and temporarily offline but expected to
be returned to service.
• Do not include intake structures that have been permanently taken offline or those
planned or under construction.
• Label the intake structures on the diagram with a plant-designated name or number,
and note the operational status.
• Provide a brief description of the source water and intake configuration (e.g., the
cooling water intake structure has 5 surface intake bays that are flush with the
shoreline on a natural cove on the Survey River)
NOTE: An annual average offlows in gallons per day (GPD) can be calculated by summing actual daily intake
flows (in MGD)for 1998 and dividing by 365 days.
(2) Indicate the average daily intake flow of new water, including makeup water, in GPD
taken into the plant through each of the plant’s intake structures.
(b) Distribution of Plant’s Intake Flow (based on 1998 flow data)
Indicate the distribution of intake flow (average daily intake flows, in GPD) from each of the
intake structures to waters used for process, contact and noncontact cabling, and nonprocess
activities within the plant.
• Note the type of activity (e.g., process, contact cooling, noncontact cooling, or nonprocess)
and the flow to each (in GPD).
• Include recirculating and recycle loops where appropriate with associated flows.

Part 2. Technical Data
(c) Discharge-Related Data (based on 1998 flow data)
(1) By discharge structure, indicate the water sources or
entities that receive the plant’s discharge by generic
name (e.g., POTW, privately-owned treatment
works, cooling canals/channels, cooling lakes,
cooling ponds, cooling towers, groundwater, or
surface water).
Include all discharge structures presently
operating, and those temporarily offline but
expected to be returned to service.
• Do not include discharge structures that are
planned, under construction, or permanently
offline.
• Please label the discharge structures on the
diagram with a plant-designated name or number,

(c) For those cooling water intake structures where fish handling and/or return systems are employed,
please provide the technology data requested in the matrices beginning on the next page.
NOTE: Response space has been provided for three d (ferent fish handling and/or return system technologies. If
you employ more than this number of technologies for a given CWIS, please copy the matrix and continue noting
your technologies. Please, however, change the technology code numbers. Attach any additional matrix sheets to
this section of the questionnaire, and identVy individual matrix sheets as Matrix “1 of 3,” “2 of 3,” etc.
Plants that employ more than one fish handling and/or return system technology at a given intake
structure should fill out a separate column in the matrix for each different technology, if a given
intake structure has multiple fish handling and/or return system technologies that are substantially
similar in design and operation, only one column of the matrix needs to be completed. However,
please report the number of technology units that are similar. If there are differences in the design
or operation of the same technology employed at one intake structure (i.e., different
manufacturers, different ages, etc.), separate columns of the matrix should be completed.

25. For each cooling water intake structure, please note in the following matrices, the daily maximum and
daily minimum cooling water intake flows (in GPD) by month for calendar years 1996 to 1998. [ Daily
average flows are calculated by summing all of the actual or calculated daily flows during a particular month and
dividing that sum by the total number of calendar days in the month.] Also, for each month during these
calendar years, please note the average daily flow (in GPD). Finally, please indicate the number of
operating hours by month by calendar year.
If flow data are unavailable for a given reporting month, please check (/) the response titled “No Data.”
For each calendar year, please indicate whether the data provided are “Actual” or “Calculated.”
NOTE: A separate matrix has been provided for two cooling water intake structures. If you have more than two cooling
water intake structures, please copy the matrix and change the cooling water intake structure code names or numbers as
appropriate. Please insert any additional matrices into this portion of the questionnaire, and iden: fy individual matrix

For the purposes of this questionnaire, the phrase “an
environmental impact” means human induced change
or pressure on the natural environment.
For the purposes of this questionnaire, Impingement refers to
the trapping and holding of aquatic organisms to the outer part
of an intake structure or against screening devices during periods of cooling water
withdrawal.
For the purposes of this questionnaire, entrainment refers to the merging of small
aquatic organisms with the flow of cooling water entering and passing through a
cooling water intake structure, and thus, into a water system.

operations within a plant to the atmosphere.
Cooling Lake: A body of water that is formed by the construction of a dam, berm, or levee in a natural
watershed and which relies on the banks of the natural watershed to provide the majority of the
containment of the impounded water. A cooling lake is a means for transferring to the atmosphere heat
added to water by facility operations.
Cooling Operations: Activities that transfer heat from one medium or activity to cooling water (with the
exception of nonprocess air conditioning).
Cooling Pond: A body of water that is formed by the construction of a dam, berm, or levee on land, has
no significant watershed, and which requires the manmade containment surround most or all of the
impounded water. A cooling pond is a means for transferring to the atmosphere heat added to water by
facility operations.

structure over a specific time-period.
G-2 Detailed Industry Questionnaire: Phase II Cooling Water Intake Structures—Traditional Steam Electric Utilities
-------
Glossary to Questionnaire
Cooling Water Intake Structure: The total structure used to withdraw water from a water source up to
the point of the first intake pump or series of pumps. The intended use of the cooling water is to adsorb
waste heat rejected from processes employed or from auxiliary operations on the plant’s premises. Single
cooling water intake structures may have multiple intake bays and could serve more than one generating
unit. If a plant has intake structures may withdraw water for purposes besides cooling, the entire intake
structure should be considered a cooling water intake structure under the questionnaire.
Cooling Water System: A system that provides water to/from a plant to transfer heat from equipment or
processes therein. The system includes, but is not limited to, water intake and outlet structures, cooling
towers, ponds, pumps, pipes, and canals/channels. For plants that use surface water for cooling, a system
begins at the first barrier(s) to ingress and/or egress by fish and other aquatic wildlife (e.g., at the weir wall,
at the trash rack, etc.) and ends at the discharge outlet(s). See also Cooling Water Intake Structure.
Cove: See Bay.
Critical Aquatic Habitat: Biological or physical features of an area that are essential for the conservation
and preservation of aquatic threatened or endangered species and may require special management
considerations or protection.
Daily Maximum Flow: The maximum flow recorded for any one day during a given month.
Daily Minimum Flow: The minimum flow recorded for any one day during a given month.
Design Through-Screen Velocity: The value assigned during the design phase of a CWIS to the speed
at which intake water passes through the intake screen (or other technology) against which organisms may
be impinged or where they may be entrained.
Discharge: When used without qualification, means the discharge of a pollutant. Discharge of a pollutant
means: (i) any discharge of any pollutant or combination of pollutants to waters of the United States from
any point source, or (ii) any addition of any pollutant or combination of pollutants to the waters of the
contiguous zone or the ocean from any point source other than a vessel or other floating craft which is
being used as a means of transportation. See also 40 CFR 122.2.
Discrete Biological Study of Entrainment: A study that has been distinctly undertaken to evaluate the
biological effects of entrainment over a specified time period. The study has discrete starting and ending
points. The purpose of the study is to evaluate the rate and/or number of organisms withdrawn from the
intake water body and into the cooling water flow and thus, into a cooling water system. The study may
involve evaluations of one or more intake structures.
Discrete Biological Study of Impingement: A study that has been distinctly undertaken to evaluate the
biological effects of impingement over a specified time period. The study has discrete starting and ending
points. The purpose of the study is to evaluate the rate and/or number of organisms are trapped against the
outer part of one or more intake structures during periods of cooling water withdrawal.
Detailed Industry Questionnaire: Phase II Cooling Water Intake Structures—Traditional Steam Electric Utilities G-3
-------
Domestic Parent Firm: The highest level domestic business entity in a facility’s organizational structure.

Entrainment: The merging of small aquatic organisms with the flow of cooling water entering and
passing through a cooling water intake structure, and, thus, into a cooling water system.
Environmental Impact: Human induced change or pressure on the natural environment.
Estuary: A semi-enclosed coastal body of water that has a free connection with the open sea and is
strongly affected by tidal action. In an estuary, sea water is mixed (and usually measurably diluted) with
fresh water from land drainage. [ NOTE: The Chesapeake Bay and the San Francisco Bay are examples of estuaries even though
the term bay appears in their name. For the purposes of this questionnaire, the term “tidal river” means the seaward most reach of a
river/stream where the salinity is .s 0.5 ppt at a time of annual low flow its surface elevation responds to the effects of coastal lunar tides.
Where the river salinity exceeds 0.5 ppt, the respective river reach will be viewed as essuarine.]
