## 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 coolingpurposes orare not directly withdrawing cooling water from surface waterand, 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:

### iv **Detailed Industry Questionnaire: Phase II Cooling Water Intake Structures—Traditional Steam Electric Utilities** 

### 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.

## General Information and Instructions

### v 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.

### vii 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 claimfor someor allof your responses to the technical questionnaire, as described in 40 CFR2.203(b) (see full text below) . Complete regulations governing confidentiality of business information (CBI) appear in 40 CFR , Part 2, Subpart B.
40 CFR2.203(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 andno 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 

#  If EPA must reveal information covered by a claim of confidentiality, the Agency will strictly follow the requirements and procedures set forth in 40 CFRPart 2, Subpart B. Overall, EPA may reveal submitted information protected by a CBI claim onlyto 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 onlyto 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.

## 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 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). 

## 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 (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 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. 

## 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. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

**P LEASE ANSWER THE REMAINING INTAKE** 
**- RELATED QUESTIONS IN THIS SECTION FOR**  **ONLY THOSE 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) con duits to other providers of cooling water (e.g., local water suppliers or other plants).

## 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. 

## Cooling Water Discharge Outfalls
6. Is the plant presently a zero-discharge plant ? [Base your determination of whether you are a zero-discharge plant on your effluent only . Do not include storm water discharges in this assessment.]



### 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. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

## 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 waterto 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 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.

## DEFINITION For the purposes of this questionnaire, the phrase “**an environmental impact**  ” means human induced change or pressure on the natural environment.



## 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. 

### 31. Has your plant ever conducted one or moreof the following types of studies at anyof 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]

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

### energy or shaft torque. This mechanical energy is used to power electric generators, which convert the mechanical energy to electricity, including combined cycle electric generating units. Submerged Intake Structure Flush with the Shoreline: An intake structure where the opening is evenly aligned with the shoreline and that always draws water from substantially below the surface of the water body. See Figure 3 for a graphical view of a submerged intake structure flush with the shoreline.



### Submerged Offshore Intake Structure: An intake structure which extends from a plant outward into a water body. The intake opening is submerged and the water is always withdrawn from below the surface of the water body. See Figure 4 for a graphical view of a submerged offshore intake structure.



### Submerged Vegetation: Vascular plants that are of significant ecological value because they provide prime habitat for aquatic species, and that live and grow completely under the surface, except that some species have flowers that may appear temporarily above the water.
Surface Intake Structure Flush with the Shoreline: An intake structure flush with the shoreline which withdraws water from or near the surface of the water body. See Figure 5 for a graphical view of a surface intake structure flush with the shoreline.

### G-13 Plan View Cross Section **Figure 5. Example of a Surface Intake Structure Flush with Shoreline**



### Surface Water: Bodies of water including lakes, ponds, or reservoirs; non-tidal rivers or streams; tidal rivers; estuaries; fjords; oceans; and bays/coves. Temporarily Offline: Cooling water systems that are presently out of commercial service but are expected to return. The category includes systems on inactive reserve and systems deactivated (i.e., systems not normally used but available for service).
Tidal Rivers: Rivers which receive regular, significant inflows of water from oceans or bays due to tidal action. [ NOTE : For the purposes of this questionnaire, the term “tidal river” means the seaward most reach of a river/stream where the salinity is < 0.5 ppt at a time of annual low flow its surface elevation responds to the effects of coastal lunar tides. Where the river s alinity exceeds 0.5 ppt, the respective river reach will be viewed as estuarine. ] 

### Total Capital Costs: The total sum of all construction costs; design, engineering, and architectural costs; equipment costs; construction material costs; instrumentation costs; installation labor costs; and allowances for funds used during construction (AFUDC).
Trash Rack: See Bar Rack. 

### Traveling or Other Intake Screen System: Devices placed at or near the opening of an intake structure to mechanically stop smaller debris and/or organisms from entering a plant’s water system. Typical Calendar Year: A year in which the facility and its cooling water intake structures are operated in a normal, routine, regular, or otherwise standard fashion. Water Body: Any number of potential sources of intake water for cooling water intake structures. Includes municipal water sources, ground well water, oceans, lakes, reservoirs, rivers, and estuaries. Water Supply of Plant Other Than Own: Water obtained or purchased from a plant other than itself. This other plant would own and operate its own onsite well or directly withdraw water from surface water or other sources of groundwater. Depending upon the intended uses of the withdrawn water, the other plant might provide treatment. Moreover, the other plant might sell the water to other entities or use it onsite. The other plant, however, would not provide potable water to residential populations like a local water supplier.

### G-14 **Detailed Industry Questionnaire: Phase II Cooling Water Intake Structures—Traditional Steam Electric Utilities** 

### Waters of the United States (U.S.): All waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters subject to the ebb and flow of the tide. Waters of the United States include, but are not limited to, all interstate waters and intrastate lakes, rivers, streams (including intermittent streams), mudflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds. The definition includes waters which are or could be used by interstate or foreign travelers for recreation or other purposes and those waters from which fish or shellfish are or could be taken and sold in interstate or foreign commerce or which are used or could be used for industrial purposes by industries in interstate commerce. Waste treatment systems, including treatment ponds or lagoons designed to meet the requirements of the CWA are not waters of the U.S. See 40 CFR 122.2 for a more complete definition. 

### Water Used for Process Activities: Water that will come in contact with or result from the production or use of any raw material, intermediate product, finished product, waste product, or wastewater. This includes water used in processes whose discharge is regulated by effluent limitations and new source performance standards and stormwater runoff which comes in contact with industrial materials or processes. For facilities covered under the Steam Electric Point Source Category (40 CFR Part 423), this would include water used for boiler makeup or freshwater, ash handling systems, metal cleaning systems, screen backwash, laboratory activities, wastewater treatment (filter backwash, demineralizer waters, etc.), and service water not otherwise designated. Weir (or Skimmer or Curtain) Wall: A device placed before an intake structure to prevent warmer surface water and floating debris from entering the intake structure.
Wetlands: Areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Zero Discharge Plant: A plant that does not return any treated or untreated plant effluent (excluding stormwater) 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.FORMAPPROVEDOMBCONTROLNO.2040-0213EXPIRATIONDATE:12/31/02

## General Information and Instructions

**Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures** 

### iii 

## General Information and Instructions **Why This Questionnaire?** The U.S. Environmental Protection Agency (EPA) is currently developing regulations 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 require 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 short technical questionnaire will help EPA identify the types and sizes of utilities that are subject to Section 316(b). Please note that data from this short technical questionnaire are not intended to identify whether a specific plant’s cooling water intake structures are having an adverse impact on the environment. Moreover, questionnaire responses are not intended to identify whether a specific plant 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 plants. The questionnaires are simply tools for characterizing some of the following: type and nature of plants 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 plants 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 short technical questionnaire consists of three main sections. Section 1 requests general plant information, such as plant name, location, and Standard Industrial Classification (SIC) codes. Section 2 requests information from plants on such topics as National Pollutant Discharge Elimination System (NPDES) permit status, whether cooling water is used and, if so, whether it is withdrawn by the plant from surface water. Finally, information is requested on the types of activities for which the plant uses cooling water directly withdrawn from surface water. The purpose of these two sections is to help EPA determine the nature of plants within an industry group that use cooling water. Additionally, the information will help EPA identify (i.e., “screen”) plants that are not subject to Section 316(b). These out-of-scope plants will be exempted from completing the remaining sections of the questionnaire. Plants that will be considered “out-of-scope” will include those that (1) are not point sources as defined under Section 502(14) of the Clean Water Act (33 U.S.C., 1362(14)), (2) do not use cooling water as that term is defined for the purposes of this questionnaire, or (3) do not receive any of their cooling water supply from a surface water source.

NOTE: Please keep a copy of the completed questionnaire and Certification Statement for your records.


### If you have extenuating circumstances that preclude you from meeting the 45 day deadline, please contact Deborah Nagle at the following email address: Survey.316b@epamail.epa.govto discuss your situation.
Confidential Business Information You may assert a business confidentiality claim for some or all of your responses to the short technical questionnaire, as described in 40 CFR2.203(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 one of the methods described above. If no claim of confidentiality has been made, 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. Note, however, that certain types of information cannot be considered confidential under the CWA (e.g., plant location, water body, water body type, intake flow data). If EPA reveals information covered by a claim of confidentiality, the Agency will strictly follow the requirements and procedures set forth in 40 CFRPart 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. Agency contractors will have access to CBI data so that work can be performed under their contracts relative to the Section 316(b) rulemaking. All EPA contracts require that contractor employees must use CBI data only to perform work specified by EPA. The information is not to be shown to anyone, other than EPA officials, without prior written approval having been received from the affected business or from EPA’s legal office.

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 ask plants to classify themselves using NAICS codes for the purposes of this questionnaire.

## DEFINITION For the purposes of this questionnaire, the term **“cooling water”**  refers to both contact and noncontact cooling water, including water used for air conditioning, equipment cooling, evaporative cooling tower makeup, and dilution of effluent heat content. The intended use of the cooling water is to absorb waste heat rejected from the process or processes employed or from auxiliary operations on the plant’s premises. 

#  **Yes** (1) 

#  **No** (2) 

## STOP If answer is No, please stop here and return questionnaire with a completed Certification Statement. 

## DEFINITIONS For the purposes of this questionnaire, **surface water** includes lakes, ponds, or reservoirs; nontidal rivers or streams; tidal rivers; estuaries; fjords; oceans; and bays/coves. A **cooling water intake structure**  is the total structure and associated technologies used to direct water from a water body into a plant up to the point of 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 might have multiple intake bays. If a plant has an intake structure that withdraws water for other purposes in addition to cooling, the entire intake structure should be considered a cooling water intake structure for the purposes of this questionnaire. 

## Section 2: General Scoping Data

5. Does the plant presently have or is the plant presently in the process of obtaining a National Pollutant Discharge Elimination System (NPDES) permit ?
NOTE: NPDES 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 directly to waters of the United States. Plants thatdischarge 100 percent of their effluent (including storm water) to publiclyowned treatment works, privately-owned treatment works, and/or to ground water injection wells should answer “No” to this question. 

### 6. Since January 1, 1996, has cooling waterbeen used for contact or noncontact cooling purposes at the plant? [Please consider all cooling water used regardless of the type of water source or provider from which it has been obtained.]



### 7. Since January 1, 1996, has the plant directly obtained any portion of its cooling water from a surface water source ?
NOTE: In order for a plant to directly withdraw cooling water from surface water, it must have an intake structure

NOTE: The following terms are defined for purposes of this questionnaire only. The definitions at present do not have any legal meaning with respect to Section 316(b) of the Clean Water Act. 

### Air Conditioning: The process and equipment used to control the temperature and humidity of indoor air. Cooling water is used in some types of air conditioning systems. Average Daily Intake Flow Rate: The total volume of cooling water withdrawn by a specific intake structure over a 24-hour day.
Bar Rack/Trash Rack: A device consisting of parallel spaced bars placed at or near the opening of an intake structure to mechanically stop debris and /or large organisms from entering a facility ’ s water system. Bay or Cove (natural or constructed) : An inlet created when the shoreline of a water body is indented. Bays are generally larger than coves but are smaller than gulfs. Coves are generally sheltered. Bays and coves are considered part of the cooling water intake structure. [ NOTE : The Chesapeake Bay and the San Francisco Bay are examples of estuaries even though the term bay appears in their name. 

### ] See Figure 1 for a graphical view of an intake structure incorporating a bay or cove. **Figure 1. Example of an Intake Structure Incorporating a Bay or Cove**



### Combined-Cycle Unit: An electric generating unit that consists of one or more gas turbines or internal combustion engines and one or more steam boilers. Part of the required input to the boiler(s) is provided by the exhaust gas (waste heat) of the combustion turbine(s). Cooling Canal/Channel: An artificial, channelized waterway used to transfer heat added to water from operations within a facility 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

## Glossary

**G-2 Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures**  

### 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. Cooling Tower: A structure which functions as a heat exchanger and is designed to provide cooling by the forced evaporation of water into an air stream using either mechanical energy (forced draft) or ambient buoyancy (natural draft) to provide the movement of the air stream through the tower. Cooling Water: Refers to both contact and non-contact cooling water, including water used for air conditioning, equipment cooling, evaporative cooling tower makeup, and dilution of effluent heat content. The intended use of the cooling water is to absorb waste heat rejected from the process or processes employed or from auxiliary operations on the facility ’ s premises. 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 facility ’ s premises. Single cooling water intake structures may have multiple intake bays and could serve more than one generating unit. If a facility 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. Cooling Water System: A system that provides water to/from a facility 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 facilities 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. 

### 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. 

### DUNS Number: A number assigned to a business using the Data Universal Numbering System (DUNS) developed by the Dun and Bradstreet Corporation.

### Effluent: Outflow of wastewater from a facility to waters of the United States. 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 questi onnaire, the term “ tidal river ” means the seaward most reach of a river/stream where the salinity is  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 w ill be viewed as estuarine. 

### ] Fish Diversion or Avoidance System: Mechanisms designed to divert or induce fish to swim away from cooling water intake structures. Fish Handling and/or Return System: Any system that collects, and/or transports live organisms from an intake structure back to the source water body at a point away from the influence of the intake. Groundwater Injection Well: A man-made or improved “ hole ” in the ground that is deeper than its widest surface dimension and is used to discharge or dispose of fluids to groundwater (the supply of water found beneath the earth ’ s surface; it is usually held in aquifers and is often the source of water for streams, springs, or wells from which it may be withdrawn). There are many types of injection wells, but they are all similar in their basic function. The Federal Underground Injection Control Program has grouped injection wells into five categories

—Class I through V wells. Intake Bays: Temporary holding areas designed to direct water toward the pump well of a specific intake structure. Intake Canal/Channel (natural or constructed) : A channelized conduit that diverts water before its passage through screens or other filtering devices and before its entrance into an intake structure. See Figure 2 for a graphical view of an intake structure employing an intake canal.



### Intake Embayment/Bay/Cove: A natural or constructed inlet along the shoreline of a water body that serves to direct water through screens or other filtering devices up to the intake pump or series of pumps. Intake Screen System: Devices placed at or near the opening of an intake structure to mechanically stop debris and/or organisms from entering a facility ’ s water system. Intake Structure: See Cooling Water Intake Structure.

Non-tidal Rivers/Streams: Rivers or streams which do not receive significant inflows of water from oceans or bays due to tidal action. North American Industrial Classification System: A new system initiated in January 1997 to classify industries. This new system replaces the existing Standard Industrial Code (SIC) system and identifies industries according to the type of production activities performed. NAICS industries are identified using a 6-digit code. NPDES (National Pollutant Discharge Elimination System) Permit: A permit required to be held under Section 402 of the Clean Water Act (33 U.S.C. 1342

### et seq .) by any point source discharging pollutants to waters of the United States. Permits may address effluent discharges, storm water, or sewage sludge management practices and may be issued by an EPA Region or a Federally-approved State NPDES program. Ocean: Marine open coastal waters other than those water bodies classified as estuaries, embayments or fjords, each of which are semi-enclosed and have readily identifiable geographic boundaries. Once-through Cooling Water System: A system designed to withdraw water from a natural or other water source, run it through a facility for contact and/or non-contact cooling purposes, and then discharge it to a water body without recirculation. Once-through cooling water systems may use canals/channels, ponds, or non-recirculating towers to dissipate waste heat from the water before it is discharged. Operating Days: The total number of days (1 day = 24 hours) a cooling water intake structure operated during a specified time period, excluding any days the cooling water intake structure was offline for routine maintenance or otherwise was not operational. A partial day (i.e., operations of less than 24 hours) does not constitute an operating day and should not be counted as such. Passive Intake System: Devices placed at or near the opening of an intake structure that, with little or no mechanical activity, stops debris and/or organisms from entering a facility ’ s water system. Most passive intake systems achieve very low withdrawal velocities at the screening medium.
Planned or Under Construction: Cooling water intake structures for which funds have been authorized and are expected to go into commercial service within the next 7 years. It does 

### not include structures that are presently operational, temporarily offline, permanently offline, or operating under test conditions.

The term does not include return flows from irrigated agriculture or agricultural storm water run off. See also 40 CFR 122.2. 

### Pond: A still body of water that is generally smaller than a lake. Presently Operating: Cooling water intake structures or cooling water systems currently taking in water for cooling purposes. Privately-Owned Treatment Works: A treatment works that is not publicly owned and whose owner is not the operator of the works. The term includes any device and system used to handle and/or treat liquid wastes. Process Operations: Industrial activities that directly result in the production of a facility ’ s primary output. Production Line: Each of the successive steps taken at a facility to produce a product, except the production line ’ s use of electricity. Publicly-Owned Treatment Works: A treatment works owned by the State or municipality. The term refers to any devices and systems used to store, treat, recycle, and reclaim municipal sewage or industrial wastes of a liquid nature. It also refers to sewers, pipes, and other conveyances only if they convey wastewater to a POTW treatment facility. Recirculating Cooling Water System: A system designed to withdraw water from a natural or other water source to support contact and non-contact cooling uses within a facility. The water is generally sent to a cooling canal/channel, lake, pond, or tower in order for waste heat to be dissipated. (Some facilities may divert the “ waste heat” to other process operations.) Once accomplished, the water is returned to the system. New source water (called make-up water) is added to the system to replenish losses due toblowdown, drift, and evaporation. For the purposes of the questionnaire, the term does not include nonrecirculating cooling canals/channels, ponds, or towers.
Reservoir: A natural or constructed basin where water is collected and stored and from where it is piped for various uses. Standard Industrial Classification (SIC) Code: A national classification system that organizes business entities into production-based and market-based categories identified by a 4-digit code. There are three levels of SIC codes: primary, secondary, and tertiary. Primary SIC codes are assigned based on the principal product or group of products produced or distributed by an establishment or for services rendered by the facility. Additional SIC codes are assigned for any secondary and tertiary products produced or for services rendered by an establishment.

## General Information and Instructions **Why This Questionnaire?** The U.S. Environmental Protection Agency (EPA) is currently developing regulations 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 will require 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 identify the types and sizes of industrial facilities that are subject to Section 316(b). After reviewing the results of the screener questionnaire, EPA will administer a more detailed technical questionnaire to a subset of in-scope facilities to characterize the design, operation, and management of their cooling water intake structures and cooling water systems. Some basic economic data will also be requested in this future survey. Please note that data from the screener and detailed questionnaires are not intended to identify whether a specific facility’s cooling water intake structures are having an adverse impact on the environment. 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 feed into other 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 min imize 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. The enclosed screener questionnaire consists of five main sections. Section 1 requests general facility information, such as facility name, location, and Standard Industrial Classification (SIC) codes. Section 2 requests information from facilities on such topics as National Pollutant Discharge Elimination System (NPDES) permit status, whether cooling water is used and, if so, whether it is withdrawn by the facility from surface water. Finally, information is requested on the types of activ ities for which the facility uses cooling water directly withdrawn from surface water. The purpose of these two sections is to help EPA determine the nature of facilities within an industry group that use cooling water. Additionally, the information will help EPA identify (i.e., “screen”) facilities that are not subject to Section 316(b). These out-of-scope facilities will be exempted from completing the remaining sections of the questionnaire. Moreover, they will be excluded from the pool of facilities that will be sampled to receive the detailed questionnaire. Facilities that will be considered “out-of-scope” for receiving the detailed questionnaire will include those that (1) are not point sources as defined under Section 502(14) of the Clean Water Act (33 U.S.C., 1362(14)), (2) do not use cooling water as that term is defined for the purposes of this questionnaire, or (3) do not receive any of their cooling water supply from a surface water source.Questionnaire No: __ __ __ __ __ __

### Section 3 requests facilities to provide basic design and operational data on their cooling water intake structures and cooling water systems. This information will help EPA ensure that it sends the detailed questionnaire to an appropriate number of facilities representing the diverse array of design configurations possible. Many of the questions are in multiple-choice format. The following types of information are being requested: total number of cooling water intake structures, originating sources of cooling water, total cooling water intake flow rates and operating days for a typical calendar year, total number of cooling water systems and their respective configurations, placement of cooling water intake structures in surface water bodies, control technologies being used at intake structures, and whether facility or firm owners have ever conducted or commissioned environmental or ecological studies of the potential impacts of any of their cooling water intake structures. Section 4 asks for information regarding the estimated numbers of full-time equivalent employees and the estimated annual sales revenue for the Facility’s Fiscal Year 1997. For facilities that are owned by a larger firm, this information is requested for the parent firm as well. This information will enable EPA to send the detailed questionnaire to a broad range of facilities, based on their size. It is especially important that EPA collect sufficient data on a representative sample of qualified small businesses to enable the Agency to comply with the Regulatory Flexibility Act (RFA). This information will also help EPA design its approach for conducting economic impact analyses of Section 316(b) regulatory options, once these options are identified. Finally, Section 5 requests information from facilities that use cooling water directly withdrawn from surface water to generate electricity. These fac ilities are asked to indicate the gross amount of electricity they have generated and their total annual sales of electricity for a recent and typical fiscal year. This information will help EPA classify in-scope facilities according to their status as electricity generators. The economic portion of the detailed questionnaire will be tailored to these specific classifications. Given the significant recent changes in the electricity industry, and the importance of cooling water in electricity generation, EPA wants to ensure that it has a full understanding of the potential impacts of regulatory options on electricity generators including nonutility and industrial generators. The economic data from both the screener and the detailed questionnaires will support EPA’s economic impact analyses of Section 316(b) regulatory options. 

## Authority EPA has authority to administer this 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? Before issuing this screener questionnaire, EPA identified approximately 18 major industry groups thought to use cooling water, other than traditional steam electric utilities. EPA ultimately narrowed its research focus to steam electric nonutility power producers and four industrial categories for which data showed large quantities of cooling water use. The four major industrial categories include the following: PaperQuestionnaire No: __ __ __ __ __ __

### and Allied Products (SIC 26), Chemical and Allied Products (SIC 28), Petroleum and Coal Products (SIC 29), and Primary Metals (SIC 33). EPA has not identified the specific facilities within each of these target groups that use cooling water, nor does the Agency know the degree to which cooling water is used within and across the groupings. Consequently, EPA is forwarding this screener questionnaire to a subset of steam electric nonutility power producers and facilities within the four targeted industry groups. Information obtained from the screener questionnaire will enable EPA to direct its detailed industry questionnaire to a representative sample of only those facilities identified through the screener questionnaire that withdraw cooling water from surface water and are point sources. Please note that although EPA is limiting the target audience to receive the screener and detailed questionnaires to the industry groups mentioned in this section, this action should not be presumed to mean that a Section 316(b) regulation would not be applicable to other industry groups.

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 ask facilities to classify themselves using NAICS codes for the purposes of this questionnaire.

### For the purposes of this questionnaire, the term **“cooling water”**  refers to both contact and noncontact cooling water, including water used for air conditioning, equipment cooling, evaporative cooling tower makeup, and dilution of effluent heat content. The intended use of the cooling water is to absorb waste heat rejected from the process or processes employed or from auxiliary operations on the facility’s premises. 

#  **Yes** (1) 

#  **No** (2) 

## STOP If answer is No, please stop here and return questionnaire with a completed Certification Statement. 

### For the purposes of this questionnaire, **surface water** includes lakes, ponds, or reservoirs; nontidal rivers or streams; tidal rivers; estuaries; fjords; oceans; and bays/coves. A **cooling water intake structure**  is the total structure and associated technologies used to direct water from a water body into a facility up to the point of 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 au xiliary operations on the facility’s premises. If a facility has an intake structure that withdraws water for other purposes in addition to cooling, the entire intake structure should be considered a cooling water intake structure for the purposes of this questionnaire.
