 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 316(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 outfalls, 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 II Cooling Water Intake Structures—Traditional Steam Electric Utilities                    Hi

-------
 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 a bay 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 316(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.

 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 (CBI) 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 (/) the
 circle at the bottom of the page or by 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  O

 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.

                      Specific Instructions for Completing the Questionnaire

  Plant personnel most knowledgeable of the subject areas covered by the questions posed should complete the
  questionnaire.  This may require that a different person be responsible for the completion of the technical
  portions (Parts 1 and  2) than the person who is responsible for the economic and financial portion (Part 3).
  Please provide an appropriate point of contact for each of these portions of the questionnaire. These persons
  may be contacted if there are questions on your responses.

     Please answer  the questions  in  sequence unless you are  directed  to SKIP  forward  in die
     questionnaire.

     Do not leave response areas blank to any question that you have been directed to answer. For many
     questions, EPA has included a response box saying "Don't Know" or "No Data Available." If one of these
     response options  is not included under a particular question, you must provide an answer.
       NOTE: Matrices that contain separate response columns for individual cooling water intake structures need not be completed
       if the information being requested is not applicable to that particular cooling water intake structure.
      For quantitative data,

        -  Please report to the nearest whole number, unless instructed otherwise. If your answer is zero,
           please record a zero in the response column. Please do not leave a response area blank.
        -  Provide actual data to the extent that they are available.  Good faith  estimates should be
           provided only when actual data are not available.

      Clearly mark responses to all questions with a black or blue ink pen, or type responses in the spaces
      provided.
      For each question, please read all instructions and definitions carefully.
      Most key terms are defined in the Glossary, which accompanies the questionnaire package. Terms which

3.  Is the plant presently in commercial service?

    NOTE:  To clarify for plants that are not in a commercial business,
    interpret this question as, "Is your plant currently operating ? "

4.  What are  the four-digit  Standard Industrial  Classification
    (SIC) codes associated with the plant's main lines of business?
    (Please use SIC codes contained in the Office of Management and Budget's 1987
    Standard Industrial Classification Manual. This listing can also be found at the
    following Internet site: www.osha.gov/cgi-bin/sic/sicser5.]
    NOTE:  Since the  1930s,  SIC codes have been used to facilitate the
    collection, tabulation, presentation, and analysis of data relating to U.S.
    business establishments by Federal statistical agencies (e.g., Office of
    Management and Budget or OMB, Bureau of the Census, etc.).  The system
    was last updated by OMB in 1987.  It was recently replaced by the North
    American Industry  Classification System (NAICS)  in 1997; however,  it
    continues to be used by many Federal agencies.  EPA believes it would be
    unnecessarily confusing to askfacilities to classify themselves using NAICS
    codes for the purposes of this questionnaire.

process of obtaining a National Pollutant Discharge
Elimination System (NPDES) permit! Q No (2)fe>
NOTE: Permits are required to be held under Section 402 of the Clean
Water Act (33 U.S. C. 1342 et seq.) by any point source that discharges
pollutants to waters of the United States. Permits may address such
topics as effluent discharges, storm water, or sewage sludge
management practices and may be issued by an EPA Region or a
Federally-approved State NPDES program. Facilities that discharge
100 percent of their effluent (including storm water) to publicly-owned
treatment works, privately-owned treatment works, and/or to ground
water injection wells should answer "No " to this question.
(b) Please indicate the NPDES permit number for the plant in

  Section A:  Plant Profile Data

  Cooling Water Systems
   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 plant as having only one cooling water system, unless your plant has systems that are
       physically separated (Le., 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
                Forthe 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 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).

  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
                withdraw 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.
          PLEASE ANSWER THE REMAINING INTAKE-RELATED QUESTIONS IN THIS SECTION FOR OM.VTHOSE INTAKE STRUCTURES RECORDED ABOVE
          UNDER Q.2. A later section in this questionnaire requests some very basic data on intake structures that are planned or under
          construction. No data are being requested on (a) intake structures that obtain cooling water via groundwater wells or (b) conduits
          to other providers of cooling water (e.g., local water suppliers or other plants).

        technology on a given cooling water system should fill
        out a separate column for each different tower. If a
        given cooling water system has multiple cooling towers
        that are designed and/or operated similarly, only one
        column of the matrix needs to be completed.  Please,
        however, report the total number of similar towers. If
        there are differences in the design or operation of cooling
        towers employed at a given cooling water system (e.g.,
        different manufacturers, different ages, etc.), a separate
        column for each matrix should be completed.

    determination of whether you are a zero-discharge plant on your effluent only.
    Do not include storm water discharges in this assessment]
QYesd)
QNo (2)
DEFINITIONS
                  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 POTW,
    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.
   7.   How many NPDES-permitted cooling water discharge
       outfalls does the plant have? Consider only those discharge
       outfalls that are presently operating or temporarily offline
       (i.e., expected to return to service). Do not consider those
       discharge outfalls planned or under construction or
       permanently offline	

   8.   Please provide the general profile data requested in the matrix
       below for each of the plant's NPDES-permitted cooling water
       discharge outfalls.
                                                                                      SKIP TO Q.9,

 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 requested. 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 of flows in gallons per day (GPD) can be calculated by summing actual daily intake
        flows (in MOD) 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,
                and please note the operational status of each
                structure.

        (2) Average daily intake flows, (in GPD) being
            discharged to each of these water sources.
        See Next Page for Example of a Plant Flow
        Distribution/Water Balance Diagram.
        Please Insert Your Water Balance Diagram at the End
        of This Section of the Questionnaire and Indicate
        Below That It Is Attached.

DEFINITIONS
                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.

 Part 2.  Technical Data
     (c)  For those cooling water intake structures where passive intake systems are employed, please
         provide the technology data requested in the following matrices.

         Plants that employ more than one passive intake system technology at a given cooling water intake
         structure should fill out a separate column in the matrix for each different technology. If a given
         intake structure has multiple passive intake 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  a  given  intake  structure (i.e., different
         manufacturers, different ages, etc.), separate columns of the matrix should be completed.

        technology.  If a given intake structure has multiple fish diversion and/or avoidance 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 a given
        intake structure (i.e., different manufacturers, different ages, etc.), separate columns should be
        completed.

 Part 2. Technical Data

 25. For each cooling water intake structure, please note in the following matrices, the daily maximum and
    dotty 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 identify individual matrix
    sheets as Matrix "1 of 3," "2 of 3," etc.

        Please answer the questions in this section of the questionnaire for only those intake structures that directly withdraw surface
        water to support contact and noncontact cooling operations within the plant.  Consider oniy those intake structures presently
        operating and those temporarily offline and expected to return to service.  Do not consider intake structures planned or under
        construction or permanently offline.
        In addition, consider only those cooling water intake structures where the facility has previously undertaken studies that would
        provide the information requested.
30. Name the aquatic species that are most susceptible to impingement and/or entrainment by one or more

       types of studies at any of its cooling water intake structures:
study to provide data and information to regulators so they
can  determine  if  an adverse environmental impact  is
occurring and/or if the location, design, construction, and
capacity of an intake structure reflects the best technology
available for minimizing adverse environmental impacts
[i.e., Section 316(b) Demonstration Study]

entrainment

discrete study to evaluate the effectiveness of a technology
to minimize impingement and/or entrainment?

ongoing  monitoring  study  of   impingement  and/or
entrainment
 DEFINITION
              For the purposes of this questionnaire, the phrase "an
              environmental impact" means human induced change
      or pressure on the natural environment.
DEFINITIONS
              For tiie 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.

            associated  with each  activity (if an activity was not
            associated  with any of the generating units, please list
            "none;" alternatively, if an activity was associated with
            all of the generating units, you may list "all");

        (3)  whether the activity used cooling water during reporting
            year 1998;

        (4)  the  names or numbers of the cooling  water intake
            structures that were associated with each  activity (if an
            activity was not associated with a cooling water intake
            structures,  please list "none").

   NOTE: When completing  column (4) of this question, please use the same
   name or number to identify each cooling water intake structure as was used

DEFINITION
               For the purposes  of  this  questionnaire, rural electric
               cooperatives are electric utilities that are owned by their
               members and are established to provide electricity to those
members. Cooperatives are incorporated under State law and are generally exempt
from Federal income tax laws. Most electric cooperatives have been  initially
financed by the Rural Utilities Service, U.S. Department of Agriculture.
                                                                                    SKIPTOQ.6

 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.

 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.
