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 salinity 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 facility'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 Facility Other Than Own: Water obtained or purchased from a facility other than itself. This other facility 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 Depending upon the intended uses of the withdrawn water, the other facility might provide treatment. Moreover, the other facility might sell the water to other G 14 Detailed Industry Questionnaire: Phase [ III] Cooling Water Intake Structures   [ Industrial Point Sources] Manufacturers entities or use it onsite. The other facility, however, would not provide potable water to residential populations like a local water supplier.

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 materials, 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 storm water 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 feed water, 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 Facility: A facility that does not return any treated or untreated facility effluent ( excluding stormwater) to surface water, a POTW, a privately owned treatment works, or a groundwater injection well. An example of a zero discharge facility might be an entity that discharges its total effluent to an evaporative pond or that completely recycles its wastewater. FORM APPROVED ˜ OMB CONTROL NO.

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.

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. gov to 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 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 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 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.

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 General Information and Instructions vi Industry Short Technical Questionnaire: Phase [ III] Cooling Water Intake Structures than EPA officials, without prior written approval having been received from the affected business or from EPA's legal office.

3. Is the plant presently in commercial service?

NOTE: To clarify for plants who 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 the 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 ask plants to classify themselves using NAICS codes 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 that discharge 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 water been 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. Section 2 General Scoping Data 4 Industry Short Technical Questionnaire: Phase [ III] Cooling Water Intake Structures 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.

8. In the matrix below, please indicate the activities for which your plant has used cooling water directly withdrawn from surface water since January 1, 1996? [ Please check ( T ) all applicable activities.]

Section Design and Operational Data 3 Industry Short Technical Questionnaire: Phase [ III] Cooling Water Intake Structures 15 THIS PAGE INTENTIONALLY LEFT BLANK Glossary Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures G 1 Plan View Glossary 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. Glossary G 2 Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures Cooling Lake: A body of water that is formed by the construction of a dam, berm, or levee in a natural watershed and which relies on the banks of the natural watershed to provide the majority of the containment of the impounded water. A cooling lake is a means for transferring to the atmosphere heat added to water by facility operations.

Cooling Operations: Activities that transfer heat from one medium or activity to cooling water ( with the exception of nonprocess air conditioning).

Cooling Pond: A body of water that is formed by the construction of a dam, berm, or levee on land, has no significant watershed, and which requires the manmade containment surround most or all of the impounded water. A cooling pond is a means for transferring to the atmosphere heat added to water by facility operations.

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.

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 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 salinity exceeds 0.5 ppt, the respective river reach will 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.

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.

Makeup Water: " New water" intended to replace water lost to evaporation, blowdown, and drift in a recirculating cooling water system. See New Water.

New Water: Water that the facility directly withdraws from a water source through an intake structure or water received from another entity. New water does not include water that is recirculated or recycled within the facility.

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.

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. Glossary Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures G 5 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.

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 to blowdown, 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. Glossary G 6 Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures Figure 3.

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.

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.

Glossary Industry Short Technical Questionnaire: Phase II Cooling Water Intake Structures G 9 THIS PAGE INTENTIONALLY LEFT BLANK ATTACHMENT 4 Response to Comments A. SUMMARY OF MAJOR COMMENTS The Agency announced a proposed extension of the information collection ( EPA ICR No.

1838.01, OMB No. 2040 0213) for 316( b) rulemaking ( 67 FR 76400, December 12, 2002).

Comments were to be submitted on or before February 10, 2003. Only one comment was submitted, a 2 ½ page comment from the National Food Processors Association.

Summary of the comment: NFPA did not address the reasons for or the need for the information collection or the burden. NFPA did not question or comment on the definition or extent of the population. NFPA adressed only the nature and phrasing of the questions, and EPA agrees with and will accommodate most of the comments. EPA's response, below, indicates in more detail the nature of NFPA's comments.

B. RESPONSE EPA thanks the NFPA for its comments on the draft short technical and long financial/ economic surveys that EPA proposed to issue to " offshore seafood processors." NFPA's comments have been very helpful in revising the questionnaires. EPA intends to change the questions to reflect almost all of the comments and suggestions from NFPA to the maximum extent practicable. EPA believes that the revised questionnaire is responsive to all of the detailed comments by NFPA and to most of the general comments by NFPA.

Responses to general comments by NFPA follow. Specific vessels will be identified to survey recipients to the extent that EPA has this information ( at this time, EPA believes that it has identified almost all relevant vessels). EPA cannot eliminate from the survey those vessels which conduct only initial preparation ( deheading, evisceration, icing, freezing). However, EPA believes that most such vessels will not be in the list of vessels surveyed, and of those which do receive a survey, most would be stopped from completing the survey at the question asking whether their water intake exceeds 2 million gallons per day ( MGD). References to " plant" or " facility" will be changed to " vessel." The time frame of information requested by year will be changed to " 2000, 2001, and 2002," or to " since January 1, 2000," and in the latter case EPA believes that the questions allow sufficient flexibility to avoid searches for past year information.

The scoping questions will stop further responses for vessels withdrawing less than 2 million gallons per day on the short questionnaire. Recipients of the questionnaires whose vessels all withdraw less than 2 MGD may need to complete the financial survey in order to enable EPA to fully assess economic impacts in the industry; thus, EPA cannot agree to the suggestion to exclude such owners from the financial survey. Questions will be revised to reflect the mobile nature of vessels, to request latitude and longitude only for vessels processing at pier side or at a mooring, to request information on the waters and regions of operation. Questionnaire instructions will note, where appropriate, that the question applies to seafood processing operations. ATTACHMENT 5 Draft Revised Questionnaires ( March 2003)

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 technical questionnaire will help EPA identify the types and sizes of Seafood Processing Vessels that are subject to Section 316( b).

Please note that data from this technical questionnaire are not intended to identify whether a specific vessel's cooling water intake structures are having an adverse impact on the environment. Moreover, questionnaire responses are not intended to identify whether a specific vessel 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 types of offshore seafood processing vessels. The questionnaires are simply tools for characterizing some of the following: type and nature of vessels 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 vessels 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 vessel 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 vessel records with reasonable diligence.

The enclosed technical questionnaire consists of four main sections. Section A requests general vessel information, such as vessel name and location. Section B requests information from vessels on such topics as National Pollutant Discharge Elimination System ( NPDES) permit status, and whether cooling water is used. Finally, information is requested on the types of activities for which the vessel uses cooling water directly withdrawn from surface water. The purpose of these two sections is to help EPA determine the nature of vessels within an industry group that use cooling water. Additionally, the information will help EPA identify ( i. e., " screen") vessels that are not subject to Section 316( b). These out of scope vessels will be exempted from completing the remaining sections of the questionnaire. Section C requests vessels to provide basic design and operational data on their cooling water intake structures and cooling water systems. Many of the questions are in multiple choice format. The following types of information are being requested: originating sources of cooling water, total cooling water intake flow rates and operating days for a typical calendar year, control technologies being used at intake structures, and whether vessel 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 D requests facility and firm economic data. It is only applicable to facility who are out of scope and therefore not required to complete the Industry Economic Questionnaire. Data requests include number of facility/ vessel full time employee and revenue, name of the General Information and Instructions iv Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels F Toll Free Help Line Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Tetra Tech, Inc.

Where to Get Help?

Certification Statement A responsible corporate official or his ( or her) duly authorized representative must verify the accuracy of the vessel's responses to the questionnaire by reading and signing the enclosed Certification Statement. This statement must be returned to EPA along with the completed questionnaire.

When and How to Return the Questionnaire?

You must complete and return the technical questionnaire and Certification Statement to EPA within 30 calendar days after receiving the materials at your vessel or firm. Please return your materials, in the enclosed self addressed envelope, to: General Information and Instructions Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels v If you have extenuating circumstances that preclude you from meeting the 30 day deadline, please contact TBD at the following email address: Survey. 316b@ epamail. epa. gov to discuss your situation.

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 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., vessel 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 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.

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.

For the purposes of this questionnaire, the term " cooling water" refers to both contact and noncontact cooling water, including water used for engine cooling, equipment cooling, 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 vessel's premises. DEFINITIONS FYes ( 1)

FNo ( 2) STOP If answer is No, please stop here and return questionnaire with a completed Certification Statement. 3. Is the vessel presently ( in 2003) in commercial service for seafood processing ( for example, as a mothership, factory trawler, catcherprocessor or processing barge)?

NOTE: To clarify for vessels which are not in a commercial business, interpret this question as " Is your vessel currently operating?"

4. Does the vessel presently have or is the vessel presently in the process of obtaining a National Pollutant Discharge Elimination System ( NPDES) permit?

NOTE: NPDES permits are required 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. Vessels 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. Your seafood processing vessel may not be required to have a NPDES permit, depending on the policies and practices of the permitting authorities for the waters where the vessel discharges seafood processing waste.

( a) Please provide the NPDES permit number for the vessel:

FYes ( 1)

FNo ( 2) STOP If answer is No, please stop here and return questionnaire with a completed Certification Statement. 6. Since January 1, 2000, has the vessel directly obtained any portion of its cooling water from a surface water source?

NOTE: In order for a vessel to directly withdraw cooling water from surface water, it must have an intake structure, such as a sea chest.

7. ( a) What is the vessel's design intake flow ( check appropriate unit) .......................................................................__________________

Definition: " Design intake flow" is the total capacity of the cooling water intake structures. A cooling water intake structure is an intake structure that withdraws any portion of water for cooling purposes, even if a large portion of that water is used for non cooling purposes. For example, if an intake structure ( e. g., seachest, deepwell) has one or more lines & pumps withdrawing from it, some supplying cooling systems, and some not ( e. g. fire mains), the capacity of all pumps withdrawing through the intake structure would be counted. If a fire main or a ballast tank is supplied through a separate intake structure ( e. g. simple pipe, seachest, or deepwell) that does not have any lines & pumps supplying cooling water, that capacity would not be counted ( this situation may occur on fixed platforms and jackup rigs, for example).

( b) Is your design intake flow less than 2 million gallons per day? Note: Section 4 is now Section D and Section 3 is now Section C.

If you answered No, proceed to the next question.

If you answered Yes, please proceed to Section 4  you do not need to answer questions in Section 3.

If you answered Yes, you do not need to answer the Industry Economic Questionnaire which accompanied this Industry Technical Questionnaire. 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 vessel up to the point of the first intake pump or series of pumps. The intended use of cooling water is to absorb waste heat. If a vessel 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.

List the components of design intake flow that are used intermittently or infrequently, and estimate the percentage of the time these are used.

Note: Interpret " intermittently or infrequently" to mean " operating less than 25% of the time that the vessel is in use." For example, the capacity of a pump used to supply fire mains may have been included when estimating design intake flow above. You would list here the pump capacity, the units reported ( for example, gpm, mgd, cfs) and the estimated percent of the time this capacity is used.

Please provide, for a typical calendar year since January 1, 2000, the total number of days the cooling water intake structure( s) was/ were operational ( Item a), and the total average daily intake flow rate in millions of gallons per day ( gpd) ( Item b). This question applies to all cooling water intake structures, in aggegate, on the vessel. Note: Please provide actual data to the extent they are readily available; otherwise, best engineering estimates may be provided.

14( a). No. of Operating Days for CWIS in Typical Calendar Year ( round to the nearest day)

Definition: For the purposes of this questionnaire, the term operating days refers to the total number of days ( 1 day = 24 hours) a cooling water intake structure was operational during a calendar year, excluding any days the intake structure was offline for routine maintenance or otherwise was not operational.

NOTE: Operating days should be determined by adding the number of hours the CWIS was operational during the year and then dividing by 24 hours per day to get the total number of operating days. For example, if a vessel has operated 5,840 hours during the calendar year, the total hours divided by 24 hours per day are equal to 243 calendar days.

THANK YOU FOR COMPLETING EPA'S INDUSTRY TECHNICAL QUESTIONNAIRE: PHASE III COOLING WATER INTAKE STRUCTURESSEAFOOD PROCESSING VESSELS. WE APPRECIATE YOUR COOPERATION. PLEASE RETURN THE QUESTIONNAIRE WITH A SIGNED CERTIFICATION STATEMENT IN THE ENVELOPE PROVIDED. 16 Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels THIS PAGE INTENTIONALLY LEFT BLANK Glossary Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels G 1 Glossary 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.

Average Daily Intake Flow Rate: The total volume of cooling water withdrawn over an average 24 hour day.

Cooling Operations: Activities that transfer heat from one medium or activity to cooling water ( with the exception of nonprocess air conditioning).

Cooling Water: Refers to both contact and non contact cooling water, including water used for equipment cooling, and dilution of effluent heat content. Cooling water may be used for the cooling of engines and related parts, cooling of desalination equipment, cooling of fish freezing equipment, cooling of equipment used for cooking crab and shrimp or other. 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 vessel'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 vessel. If a vessel has intake structures that withdraw water for purposes in addition to cooling, the entire intake structure should be considered a cooling water intake structure.

Cooling Water System: A system that provides water to/ from a vessel to transfer heat from equipment or processes therein. The system includes, but is not limited to, seachests, through hull penetrations, simple pipes, pumps or other water intake structures. For vessels 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 seachest screen) 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.

Effluent: Outflow of wastewater from a vessel to waters of the United States.

Entrainment: The merging of small aquatic organisms with the flow of cooling water entering and passing through a cooling water intake structure, and, thus, into a cooling water system.

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 Glossary G 2 Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels though the term bay appears in their name. For the purposes of this questionnaire, the term " tidal river" means the seaward most reach of a river/ stream where the salinity is # 0.5 ppt at a time of annual low flow its surface elevation responds to the effects of coastal lunar tides. Where the river salinity exceeds 0.5 ppt, the respective river reach will be viewed as estuarine.]

Impingement: The trapping and holding of larger aquatic organisms to the outer part of an intake structure or against screening devices during periods of cooling water withdrawal.

Intake Screen System: Devices placed at or near the opening of an intake structure to mechanically stop debris and/ or organisms from entering a vessel's water system.

Intake Structure: See Cooling Water Intake Structure.

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.

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.

Point Source: Any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharged. The term does not include return flows from irrigated agriculture or agricultural storm water run off. See also 40 CFR 122.2.

Process Operations: Industrial activities that directly result in the production of a vessel's primary output.

Production Line: Each of the successive steps taken on a vessel to produce a product.

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.

Surface Water: Bodies of water including lakes, ponds, or reservoirs; non tidal rivers or streams; tidal rivers; estuaries; fjords; oceans; and bays/ coves. Glossary Industry Technical Questionnaire: Phase III Cooling Water Intake Structures Seafood Processing Vessels G 3 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).

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.

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.
