### 1. Identification of the Information Collection

1a. Title of the Information Collection TI TLE: Information Collection Request for Cooling Water Intake Structure Phase I I Existing Facilities EPA I CR Number: 2060.03 1b. Short Characterization/Abst ract The section 316(b) Phase I I Existing Facility rule requires the collection of information from existing point source facilities that generate and transmit electric power (as a primary activity ) or generate electric power but sell it to an other entity for transmission, use a cooling water intake structure (CWI S) that uses at least 25 percent of the water it withdraws from waters of the U.S. for cooling purposes, and have a design intake flow of 50 million gallons per day (MGD) or more. Sect ion 316(b) of the Clean Water Act (CWA) requires that any standard established under section 301 or 306 of the CWA and applicable to a point source must require that the location, design, construction and capacity of CWI Ss at that facility

reflect the best technology available (BTA) for minimizing adverse environmental impact. Such impact occurs as a result of impingement (where fish and other aquatic life are trapped on technologies at the entrance to CWI S) and entrainment (where aquatic organisms, eggs, a nd larvae are taken into the cooling sy stem, passed through the heat exchanger, and then pumped back out with the discharge from the facility

). The 316(b) Phase I I rule establishes requirements applicable to the location, design, construction, and capacity of CWI Ss at Phase I I existing facilities. These requirements establish the BTA for minimizing adverse environmental impact associated with the use of CWI Ss. Existing electric power generating facilities that do not meet the threshold requirements in § 12 5.91 of the Phase I I rule are not covered by this Information Collection Request (I CR). All Phase I I existing facilities must reduce impingement mortality for all life stages of fish and shellfish by

80 to 95% from the calculation baseline. Some Phase I I existing facilities must also reduce entrainment for all life stages of fish and shellfish by 60 to 90% from the calculation baseline. A Phase I I existing facility may choose one of the following five compliance alternatives in § 125.94(a) for establishing BTA for minimizing adverse environmental impact at the site:
1. i. Demonstrate that it has reduced, or will reduce, its flow commensurate with a closed

cycle recirculating sy stem. In this case, the facility will not be required to demonstrate further that it meets the impingement mortality and entrainment performance standards; or ii. Demonstrate that it has reduced, or will reduce, its maximum through

- screen design intake velocity

to 0.5 ft/s or less. In this case, the facility will not be required to de monstrate further that it meets the performance standards for impingement mortality ;June 2010 2

2. Demonstrate that its existing design and construction technologies and/or operational measures meet the performance standards specified in § 125.94(b); 3. Demonstrate that the facility has selected design and construction technologies and/or operational measures that will, in combination with any existing design and construction technologies and/or operational measures meet the performance standards specified in § 125.9 4(b); 4. Demonstrate that the facility has installed, or will install, and properly operate and maintain an approved design and construction technology in accordance with § 125.99(a) or (b); or 5. Demonstrate that the facility has selected, installed, and is properly operating and maintaining, or will install and properly operate and maintain design and construction technologies and/or operational measures determined to be the BTA for the facility in accordance with § 125.94(a)(5)(i) and (ii).The facility must meet one of two cost tests: (1) demonstrate that costs of compliance under alternatives 2

–4 would be significantly greater than costs considered by the Administrator, or (2) demonstrate that costs of compliance under alternatives 2

–4 would be signific antly greater than the benefits of complying with the applicable performance standards at the facility

. The Section 316(b) Phase I I Existing Facility rule requires several distinct ty pes of information collection as part of the National Pollutant Discharg e Elimination Sy stem (NPDES) application. Ingeneral, the information is used to identify which of the performance standard requirements in the rule apply

to the facility , how the facility is meeting these requirements, and whether the facility is meeting the performance requirements. Specific data requirements that apply to all facilities regardless of the compliance alternative selected are:
1. Source water phy sical data that shows the phy sical configuration of all source waterbodies used by

the facility , i dentifies and characterizes the source waterbody ’s hydrological and geomorphological features, and provides location through maps; 2. CWI S data that shows the configuration and location of cooling water intake structures, provides details on the design operat ion of each CWI S, and diagrams flow distribution and water balance; and 3. Cooling water sy stem data that characterizes the operation of the cooling water sy stem and its relationship to the CWI S Additionally , most Phase I I existing facilities must submit a C omprehensive Demonstration Study (CDS) that characterizes the source water baseline in the vicinity of the intake structure(s), characterizes operation of the cooling water intake(s), and confirms that the design and construction technology (ies) and/or ope rational measures proposed and/or implemented at the CWI S meet the applicable national performance standards specified in § 125.94. The required components of the CDS that a Phase I I existing facility must submit are dependent on the compliance alternative selected. Facilities that choose to meet the performance standards under the compliance alternative in § 125.94(a)(1)(i) are not require to submit a CDS. Facilities that choose to meet the performance standards under the compliance alternative in § 125.94 (a)(1)(ii) are required to only

submit a CDS for the entrainment requirements, if applicable. Facilities that choose to meet the performance standards under the compliance alternative in § 125.94(a)(4) areJune 2010 3

required to submit only

the Technology

Installatio n and Operation Plan and the Verification Monitoring Plan. Facilities that are required to meet only impingement mortality

reduction requirements in § 125.94(b)(1) are required to submit only a CDS for the impingement mortality reduction requirements. The CDS includes the following data requirements.
1. Proposal for information collection that describes the proposed and/or implemented technology (ies) and/or operational measures to be evaluated in the study ; describes any historical studies that are proposed t o be used in the study ; summarizes any past, ongoing, or voluntary

consultation with fish and wildlife management agencies (including a copy of written comments received as a result of such consultation); and provides a sampling plan for any

new field stud ies proposed to be conducted; 2. Source waterbody

flow information to support the determination of whether the facility is designed to withdraw more than 5% of the annual mean flow for intakes located in freshwater rivers/streams, and a description of the wat erbody thermal stratification for intakes located in lakes or reservoirs to show that the total design intake flow will not disrupt the natural thermal stratification or turnover pattern (where present) of the source water in a way

that adversely

impacts f isheries; 3. Impingement Mortality and/or Entrainment Characterization Study that provides information to support the development of a calculation baseline for evaluating impingement mortality

and/or entrainment and to characterize current impingement mortali ty and/or entrainment; 4. Design and Construction Technology Plan and a Technology

Installation and Operation Plan that includes technology and compliance assessment information that explains the design and construction technologies and operational measures that are in place or have been selected to reduce impingement mortality and/or entrainment; calculates the reduction in impingement mortality and entrainment that would be achieved by the selected technologies and operational measures; and demonstrates that the location, design, construction and capacity of the CWI S have been selected to reflect BTA at the site; 5. Verification monitoring plan that describes the monitoring that will be used to verify the full

- scale performance of the proposed or implemented tec hnologies and/or operational measures. Additional data requirements apply to facilities that choose to request a site

- specific determination of BTA for minimizing adverse environmental impact i.e., with the compliance alternative in § 125.94(a)(5)(i) or ( ii). Specific data requirements that would apply to such a facility include:
1. Comprehensive cost evaluation study that documents the cost of implementing the design and construction technologies and/or operational measures to meet the applicable performanc e standards and a demonstration that the cost is significantly greater than those costs considered by

the Administrator; 2. Benefits valuation of reducing impingement and entrainment that uses a comprehensive methodology

to fully value the impacts of impingem ent mortality and/or entrainment at the site and the benefits achievable by compliance with the applicable requirements;June 2010 4

3. A narrative description of any non - monetized benefits that would be realized at the facility if it were to meet the performance standar ds and a qualitative assessment of their magnitude and significance; 4. Site

- specific technology plan that describes the design and operation of all design and construction technologies and/or operational measures that the facility has selected; demonstrates the efficacy of the technologies; and demonstrates that the design and construction technologies and/or operational measures selected would reduce impingement mortality

and/or entrainment to the extent necessary to satisfy the requirements of § 125.94; and includes design calculations, drawings, and estimates to support the plan.
Inaddition to the information requirements of the NPDES permit application, NPDES permits normally specify monitoring and reporting requirements to be conducted by the permitted entity

. Monitoring must be conducted in accordance with the Verification Monitoring Plan required by § 125.95(b)(7) and the Technology Installation and Operation Plan required by § 125.95(b)(4)(ii), and any additional monitoring specified by the Director t o demonstrate compliance with the applicable requirements of § 125.94. The results of each facility ’s monitoring efforts are to be reported to the permitting Director every two y ears. Finally , facilities are required to maintain records of all submitted d ocuments, supporting materials, and monitoring results for at least 3 y ears (or as directed by the Director). Facilities are also required to perform a verification study to demonstrate that they

are meeting the required level of impingement mortality and entrainment reduction, as appropriate. Authorized State Directors are required to review all materials submitted to them by the facilities within the scope of the regulation, confirm their compliance with the Section 316(b) Phase I I Existing Facility

rule , and issue NPDES permits with appropriate conditions to minimize adverse environmental impact associated with the use of the facilities’ CWI Ss. As suggested, the primary users of the data collected under the 316(b) Phase I I Existing Facility rule are the States authorized to administer the NPDES permitting program, and EPA. Other government agencies, both at the State and Federal level, as well as public interest groups, private companies, and many individuals also use the data. The 316(b) Phase I I rule was signed on February 16, 2004. Industry

and environmental groups, and a number of states filed legal challenges to the rule. Several issues were heard by the Second Circuit’s Court of Appeals, which issued a decision on January 25, 2007 remanding portion s of the rule (see Riverkeeper, Inc. v. U.S. EPA , No. 04

- 6692

- ag(L) [2d Cir. Jan. 25, 2007]). EPA subsequently

suspended the Phase I I rule on July 9, 2007 and directed permit writers to continue to issue permits with 316(b) requirements developed using the permit writer’s best professional judgment (BPJ). Industry groups petitioned and were granted certiorari from the Supreme Court, which issued a decision on April 1, 2009 ( Entergy Corp. v. Riverkeeper, Inc. , No. 07

- 588). EPA is currently

in the process of developing a revised rule for existing facilities.June 2010 5

EPA believes that the burden estimated in this I CR is likely to represent an upper bound on the burden that the public would incur in complying with BPJ

- based permitting requirements for cooling water in take structures as large existing power plants over the next three years. EPA will submit a revised I CR with the new rule that reflects the specific requirements in the new rule. The revised I CR will replace this one when the new rule is promulgated. Duri ng the 3 y ears covered by this I CR (which correspond to y ears 7

– 9 after rule promulgation) the information collection required by the rule will involve responses from an estimated total of 506 facilities and 42 States and Territories and cost approximately $223 million (including operation and maintenance costs), with an annual average of 514 respondents, 1,023,521 burden hours, and a cost $74 million per y ear (for additional detail, see Section 6 and Exhibit A.11 in Appendix A). 

### 2. Need for and Use of the Collection

2a. Need/Authority for the Collection The following sections describe the need for this information collection and the legal authority under which this information will be collected. 2a(i). Need for the Collection The information re quirements of the 316(b) Phase I I Existing Facility rule are necessary

to ensure that Phase I I existing facilities are complying with the CWA’s provisions to establish BTA for CWI Ss, and thereby

minimizing adverse environmental impact resulting from imping ement and entrainment losses due to the withdrawal of cooling water. 2a(ii). Authority for the Collection Section 316 was included in the Federal Water Pollution Control Act of 1972 for the express purpose of regulating thermal discharges and to address th e environmental impact of CWI Ss. Moreover, Section 316(b) is the only provision in the CWA that focuses exclusively on water intake. Section 316(b) provides that, “[a]ny standard established pursuant to [CWA Section 301] or [CWA Section 306] and applicable to a point source shall require that the location, design, construction, and capacity of CWI Ss reflect the BTA for minimizing adverse environmental impact.” The requirements of Section 316(b) are closely linked to several of the core elements (e.g., Secti ons 301, 304, 306 and 402) of the NPDES permit program established under the CWA. Conditions implementing Section 316(b) are and will continue to be included in NPDES permits issued under Section 402 of the CWA. 2b. Practical Utility/Users of the Data The 316(b) Phase I I Existing Facility rule includes both information that must be submitted to permitting authorities and data that must be collected and maintained on

- site by the facility . Each Phase I I existing facility

maintains facility

- level records of the characterization data, plans,June 2010 6

measurements, diagrams, and calculations submitted to the Directors, as well as the analy tical results of monitoring actions. Facilities could use the data to:

 Characterize environmental conditions and monitor existing CWI S performance;

 Determine appropriate design and construction technologies or operational measures; and/or

 Monitor the performance of design and construction technologies or operational measures. Permit writers will also use these data to veri fy that the appropriate compliance actions are selected and implemented. Under the 316(b) Phase I I Existing Facility rule, EPA and State Directors are to maintain records compiled from the regulated facilities. Much of the basic information obtained from the NPDES permit application is stored in EPA’s Permit Compliance Sy stem (PCS) database

— in the process of being replaced by the Integrated Compliance In formation Sy stem (I CI S

- NPDES). PCS and I CI S

- NPDES are used to track permit limits, permit expiration dat es, monitoring data, and other data, and provide EPA with a nationwide inventory of permit holders. EPA Headquarters uses the information contained in PCS and I CI S

- NPDES databases to develop reports on permit issuance, backlog, and compliance rates. The Agency also uses the information to respond to public and congressional inquiries, develop and guide its policies, formulate its budgets, assist States in acquiring authority for permitting programs, and manage the NPDES program to ensure national consiste ncy in permitting. States can use this initial permit information along with the additional documentation and the bi

- annual reports to track facility monitoring, compliance violations, and enforcement activities. Permittees must reapply

for NPDES permits every 5 y ears. The re

- application process is the primary mechanism for obtaining up

- to

- date and new information concerning on

- site conditions. Although under the 316(b) Phase I I Existing Facility rule, existing facilities provide data from self

- monitoring activities in bi

- annual reports to the permitting authority , these reports are a less comprehensive information

- gathering process than the permit application process. EPA and States will use re

- application data to identify new species at risk or other pote ntial concerns that could lead the permit writers to take the following actions:

 Specify

additional permit limitations;

 Assess compliance with applicable standard requirements; or

 Place appropriate special conditions in permits. Environmental and citizen groups are expected to use the data collected under the 316(b) Phase I I Existing Facility

rule to independently

assess impingement and entrainment rates for affected waterbodies in their location. In addition, the data will be useful for the scientific co mmunity for assessing the impact of CWI Ss on recreational and commercial fisheries productivity and aquatic ecosy stem health.June 2010 7



### 3. Nonduplication, Consultations, and Other Collection Criteria The following sections verify and affirm that this I C R satisfies the Office of Management and Budget’s (OMB) data

- collection guidelines, has public support, and does not duplicate another collection. 3a. Nonduplication Given that the Phase I I Existing Facility rule applies to existing facilities , current data sources may already exist for the information required under the rule. Therefore, it was important that EPA review existing data sources to identify currently available information on entities subject to Section 316(b) regulation and to ensure that the data requested by the rule are not otherwise accessible. Data sources reviewed included data collected by offices within EPA; data, reports, and analy ses published by other Federal agencies; reports and analy ses published by industry ; and publi cly

available financial information compiled by government and private organizations. From this effort, EPA has determined that the information collection and reporting requirements considered in this I CR are not contained or duplicated in other routinely collected documents or reports. 3b. Public Notice Required Prior to ICR Submission to OMB Incompliance with the 1995 Paperwork Reduction Act (PRA), any agency developing a non

rule

- related I CR must solicit public comments before submitting the I CR to OMB. These comments, which are used partly to determine realistic burden estimates for respondents, must be considered when completing the Supporting Statement that is submitted to OMB. This I CR was published in the Federal Register on XXXX XX, 2010. The noti ce included a request for comments on the content and impact of these information collection requirements on the regulated community . EPA received no comments on this I CR. 3c. Consultations EPA will finalize the requirements addressed in this IC R after its publication in the Federal Register to allow for comments from the public and the regulated community . No formal consultations with persons outside EPA have occurred since the original 316(b) Phase I I Existing Facility rule and its correspond ing I CR were published in 2004. However, the Agency does consider, and act on, the comments it receives in its daily dealings with the public and with the regulated community . EPA Headquarters staff responsible for program oversight in the applicable progr am areas were contacted to provide revised information and data for this I CR. 3d. Effects of Less Frequent Collection EPA has concluded that less frequent data collection may fail to identify

in a timely

manner adverse environmental impact res ulting from the operation of existing CWI Ss. In addition, less frequent collection would also hinder the ability of EPA, States, and facility operators to take advantage of technological improvements in impingement and entrainment technologies as they beco me available, or to track long

- term trends.June 2010 8

3e. General Guidelines The information collection requirements of the 316(b) Phase I I Existing Facility rule are in accordance with the PRA guidelines at Title 5 of the Code of Federal Regulations (C FR) 1320.5(d)(2). Requests for supplemental information for the purposes of emergency response or enforcement activities are exempt from the PRA requirements. 3f. Confidentiality Applications for an NPDES permit may contain confidential busine ss information. However, EPA does not consider the specific information being requested by the 316(b) Phase I I Existing Facility rule to be ty

pical of confidential business or personal information. I f a respondent does consider this information to be of a confidential nature, the respondent may request that such information be treated as such. All confidential data will be handled in accordance with 40 CFR § 122.7, 40 CFR Part 2, and EPA's Security Manual Part I II, Chapter 9, dated August 9, 1976. 3g. Sensi tive Questions The Section 316(b) Phase I I Existing Facility rule does not require respondents to divulge information pertaining to private or personal information, such as sexual behavior or religious beliefs. Therefore, this section is not applicable. 

### 4. The Respondents and the Information Requested

4a. Respondents/SIC/NAICS The applicability

criteria of the 316(b) Phase I I Existing Facility rule at § 125.91 define an existing facility

as a Phase I I existing facility subject to this regulation if it is a point source that uses or proposes to use a CWI S, both generates and transmits electric power or generates electric power but sells it to another entity for transmission, has at least one CWI S that uses at least 25 percent of the water it withdraws from waters of the U.S. (measured on an average annual basis) for cooling purposes, and has a design intake flow of 50 MGD or more. Use of a CWI S includes obtaining cooling water by any sort of contract or arrangement with an independent supplier (or multiple sup pliers) of cooling water if the supplier or suppliers withdraw(s) water from waters of the United States. Use of cooling water does not include obtaining cooling water from a public water sy stem or use of treated effluent that otherwise would be discharged to a water of the United States. Respondents include existing electric power generating facilities. Facilities in the traditional steam electric utility

category are classified under Standard Industrial Classification (SI C) codes 4911 and 493, while nonutility power producers are classified under the major code that corresponds to the primary purpose of the facility

(e.g., the primary

code may

be SI C 49 if the primary purpose of the facility

is to generate electricity

). Nonutility

power producers affected by the Phase I I Existing Facility rule are anticipated to be classified under SI C 49 (i.e., their primary purpose is to generate electricity ); nonutility

power producers classified under other SI C codesJune 2010 9

(i.e., whose primary

purpose is not generating electricity ) are not 316(b) Phase I I existing facilities. SI C and NAI CS Codes are provided in Table 1.

Industry Categories and SIC Codes for 316(b) Phase II Existing Facility Rule Respondent Industry Categories SIC Codes NA ICS Codes Trad itional Steam Electric Utilities SIC codes 4911 and 493 221112, 221113, 221119, 221121, 221122 Steam Electric Nonutility Power Producers: Nonindustrial SIC Major Group 49

4b. Information Requested The following sections provide details on data items req uested and associated activities that the 316(b) Phase I I Existing Facility rule requires respondents to provide in their application. The two principal respondent categories are Phase I I existing facilities subject to the rule and NPDES program Directors (i.e., States and Territories authorized under CWA Section 402(b) to administer the NPDES permit program, and EPA Regional offices). There are currently 46 States and the Virgin I slands authorized under CWA Section 402(b) to implement the NPDES permit prog ram. In formation requirements for Phase I I existing facilities will differ depending on the compliance alternative selected by

the applicant. As discussed in Section 1, five compliance alternatives are available to an existing facility . Certain informatio n requirements are applicable to all Phase I I existing permitted facilities; other information requirements apply on the basis of the compliance alternative selected. 4b(i). Data Items, Including Record Keeping Requirements Data items required by

the 316(b ) Phase I I Existing Facility rule are gathered for either record keeping or reporting purposes. There are several data items that are collected only during the ye ar(s) before the beginning of each permit cycle and others that are required to be collected o n an annual basis. A discussion of all reporting requirements follows below. Reporting Requirements The Section 316(b) Phase I I Existing Facility rule does not require Directors to prepare or submit any reports beyond what is currently require d of them under the NPDES program. However, Directors need to review, maintain records of, and make permitting determinations on the basis of all documents and reports submitted to them by Phase I I existing facilities. Phase I I existing facilities must re port with their application the information required under § 125.95 and paragraphs (r)(2), (3), and (5) of § 122.21. At the time a Phase I I existing facility submits its NPDES permit renewal application (approximately 180 day s before expiration of its curr ent permit, in accordance with § 122.21(d)(2)), it must submit information demonstrating that it is employing, or will employ BTA for its CWI S to minimize adverse environmental impact in compliance with Section 316(b) of the CWA. Three ty pes of information are required to be included in the NPDES permit applications for all Phase I I existing facilities:June 2010 10

1. Source water phy sical data, as required under § 122.21(r)(2). Source water information is required to evaluate potential impact to the waterbody in whic h the intake structure is placed. Ty

pically , intake structures are located offshore, at the shoreline, or at the end of an approach intake canal. The intake structure affects different species or life stages depending on its location in the source water an d the source water ty pe. In addition, the proximity of the intake structures to sensitive aquatic ecological areas might result in potential environmental impact. 2. CWI S data, as required under § 122.21(r)(3). Facilities are required to submit information on the intake structure design and operation and the facility ’s water balance to evaluate the potential for impingement and entrainment of aquatic organisms. I nformation on the design of the intake structure and its location in the water column allows EPA to evaluate which species or life stages would potentially be subject to impingement and entrainment. In formation on the operation of the intake structure and a diagram of the facility ’s water balance would be used to identify the proportion of intake wat er used for cooling, make

up, and process water and to evaluate whether the effects of the intake would be continuous, intermittent, or seasonal. The water balance diagram also would provide a picture of the total flow in and out of the facility

. 3. Coolin g water sy stem data, per the requirements at § 122.21(r)(5). Facilities are required to submit cooling water sy stem data for the purpose of evaluating the relationship between the cooling water sy stem and the associated intake(s) and determining whether th e facility

uses at least 25 percent of the water it withdraws for cooling purposes. Depending on the compliance alternative selected, a facility may also need to conduct a CDS as stipulated at § 125.95(b)(1) through § 125.95(b)(7) as applicable. The CDS i s necessary to characterize the source water baseline in the vicinity of the intake, characterize the operation of the cooling water intake, and confirm that the design and construction technology (ies) and/or operational measures proposed and/or implemente d at the intake meet the applicable requirements of § 125.94. The CDS includes the following components:
1. A proposal for information collection [§ 125.95 (b)(1)]; 2. Source waterbody

flow information [§ 125.95 (b)(2)]; 3. An Impingement Mortality and/o r Entrainment Characterization Study [§ 125.95 (b)(3)]; 4. Technology

and compliance assessment information [§ 125.95 (b)(4)]; 5. In formation to support site

- specific determination of BTA for minimizing adverse environmental impact [§ 125.95 (b)(6)]; and 6

 Calculations of the reduction in impingement mortality and entrainment of all life stages of fish and shellfish that would be achieved by the technologies and/or operational measures the facility

has selected on the basis of the Impingement Mortality and/or Entrainment Characterization Study . In determining compliance with the requirements to reduce impingement mortality or entrainment, the facility must first determine the calculation baseline upon which to assess the total reduct ion in impingement mortality and entrainment. Reductions in impingement mortality and entrainment from this baseline as a result of any design and construction technologies and/or operational measures already

implemented at the facility should be added to the reductions expected to be achieved by

any additional design and/or construction technologies that will be implemented. Facilities that recirculate a portion of their flow, but do not reduce flow sufficiently

to satisfy the compliance option in § 125.94 (a)(1)(i) may take into account the reduction in impingement mortality and entrainment associated with the reduction in flow when determining the net reduction associated with existing technology and/or operational measures. This estimate must include a si te

- specific evaluation of the suitability of the technologies based on the species that are found at the site, and/or operational measures and may be determined on the basis of representative studies (i.e., studies that have been conducted at CWI Ss located in the same waterbody ty pe with similar biological characteristics) and/or site

Director Activities NPDES program Directors will act to ensure the implementation of the section 316(b) requirements as established under § 125.98. Section 316(b) requirements are implemented for a facility through an NPDES permit. Directors will be involved in reviewing application studies and developing permit conditions. Following receipt of a permit application, under the section 316(b) Phase I I Rule requirements , the Director will conduct the following activities as described in § 125.98(a) and (b) and below. Application Activities The Director must determine which of the standards specified in § 125.94 apply to the facility . In addition, the Director must review materials to determine compliance with the applicable standards. If a facility submits a request in accordance with § 125.95(a)(3) to reduce the information about its CWI Ss and the source waterbody required to be submitted in its permit application (this request is not authorized in the first permit term after promulgation of this rule), the Director must approve the request within 60 day s if conditions at the facility and in the waterbody

remain unchanged since the facility ’s previous application. At each permit renewal, the Director must review the application materials and monit oring data to determine whether new or revised requirements for design and construction technologies or operational measures should be included in the permit to meet the national performance standards in § 125.94 or alternative site

- specific requirements e stablished pursuant to 125.94(a)(5). The Director should review materials submitted by the applicant before each renewal period to determine if there have been any changes in facility

operations or phy sical and biological attributes of the source waterbody. Any changes should be evaluated to determine the need for additional or more stringent conditions in the permit. Permitting ActivitiesJune 2010 20

The Director must determine, using the information submitted by the existing facility

in its permit appli cation, the appropriate requirements and conditions, as described in § 125.98(b)(1) through § 125.98(b)(4), to include in the permit on the basis of the compliance alternative in § 125.94(a) selected by

the facility . The Director must perform the following in developing permit conditions: (1) Develop Cooling Water Intake Structure Requirements . Requirements that implement the applicable provisions of § 125.94 must be included in the permit conditions. The Director must evaluate the performance of the design an d construction technologies and/or operational measures proposed and implemented by the facility

and require additional or different design and construction technologies and/or operational measure, if needed to meet the applicable impingement mortality and entrainment reduction, or production, requirements. Indetermining compliance with the performance standards for facilities proposing to increase withdrawals of cooling water from a lake (other than a Great Lake) or a reservoir in § 125.94(b)(3), the Dire ctor must consider anthropogenic factors (those not considered “natural”) unrelated to the Phase I I existing facility ’s CWI Ss that can influence the occurrence and location of a thermocline. Anthropogenic factors may include source water inflows, other wat er withdrawals, managed water uses, wastewater discharges, and flow/level management practices (e.g., some reservoirs release water from deeper bottom lay ers). The Director must coordinate with appropriate Federal, State, or Tribal fish and wildlife agenci es to determine if any disruption of the natural thermal stratification resulting from the increased withdrawal of cooling water is beneficial to the management of fisheries. The Director must also determine whether to impose more stringent conditions to c omply

with the requirements of other applicable State and Tribal law, or other Federal Law. To develop appropriate requirements for the CWI S(s), the Director must do the following: (i) Review and approve the Design and Construction Technology Plan require d in § 125.95(b)(4) to evaluate the suitability and feasibility

- annual status report . Facilities must specify monitoring data and other information to be included in a status report every 2 y ears. The other information may include operation and maintenance records, summaries of adaptive management activities , or any other information that is relevant to determining compliance with the terms of the facility ’s Technology Operation and Installation Plan.



### 5. The Information Collected

CAgency Activities, Collection, Methodology and Information Management The following sections describe EPA activities related to analy zing, maintaining, and distributing the information collected. 5a. Agency Activities EPA is responsible for overseeing the implementation section 316(b) Phase requirements. Impl ementation of reporting and monitoring requirements would rely extensively

on State governments in those States that have authorization under CWA Section 402(b) to implement the NPDES permit program. In States that do not have NPDES permitting authority , E PA is responsible for administering the program. Under these circumstances, EPA performs the same activities as those outlined for Directors in Section 4. EPA ty pically reviews NPDES permits in the early stages of implementation of new regulations. As suc h, EPA assumed that it would perform a detailed review, make comments, and follow up on comments for the 316(b) portions of State

- issued NPDES permits, during the first 3 y ears after promulgation. This I CR covers y ears 7, 8, and 9 after promulgation; there fore, no burden for EPA review of State

- issued NPDES permits is anticipated to occur in this I CR period. 5b. Collection Methodology and Information Management The 316(b) Phase I I Existing Facility rule provides minimum requirements regarding the ty pe of information collected. Directors of NPDES programs are primarily responsible for determining which collection method and information management strategy is most appropriate. EPA will maintain some of the compliance data in its PCS database

— in th e process of being replaced by the I CI S

- NPDES. PCS and I CI S

- NPDES are national computerized management information sy stems that provide for entry , updating, and retrieval of NPDES data and track permit issuance, permit limits and monitoring data, and other data pertaining to facilities regulated under NPDES. This technology

reduces the burden to the permitting authority of gathering, analy

zing, and reporting national permit and water quality data. Permitting authorities are responsible for reviewing permit applications, permits, monitoring reports, and so on to verify the accuracy

of the data. Permitting authorities are also responsible for entering that data into PCS/I CI S. Authorities have differing approaches for entering the data into PCS/I CI S and for ch ecking data quality . This includes the use of coding forms, direct entry , batch uploads, and so on. Many States have developed State databases that are tailored to theirJune 2010 24

needs; interfaces are being developed for uploads directly to I CI S

- NPDES from State sy stems. Permit data can be accessed by the public in one of three way s:

 Via the Freedom of Information Act (FOIA) by submitting a request to EPA or the State.
 Via an online query

using EPA’s Envirofacts Data Warehouse and Applications Web site at http://ww w.epa.gov/enviro/index.html. Accessing data via Envirofacts provides a method to combine PCS/I CI S

- NPDES data with other EPA databases and mapping tools.
 Via some State Web sites. 5c. Small Entity Flexibility The applicability

requirements in § 125.94 exclude most existing small entities from the 316(b) Phase I I Existing Facility rule. As a result, the 316(b) Phase I I Existing Facility rule affects only

a small absolute number of facilities owned by small entities, representing a very small per centage of all facilities owned by

small entities in the electric power industry . EPA estimated that 25 in

scope electric generators owned by small entities (out of a total of 543 estimated in

- scope electric generators) are regulated by the 316(b) Phase I I Existing Facility rule. Of the 25 generators, 16 are projected to be owned by a municipality , 6 by

a rural electric cooperative, 2 by a municipal marketing authority , and 1 by a political subdivision. In addition, EPA estimated that only a small percentag e of all small entities in the electric power industry , approximately 1.3 percent, are subject to the 316(b) Phase I I Existing Facility rule. EPA considers the information collection and reporting requirements to be the minimum necessary to ensure that th e Section 316(b) goal of “minimizing adverse environmental impact” is met. Because small entities constitute a very small share of the potentially affected facilities and because only

a small percentage of all small entities in the electric power industry are subject to the rule, providing them greater flexibility such as less frequent data collection and reporting requirements would not have a large effect on the overall burden, but doing so could have an adverse impact on the effectiveness of the 316(b) P hase I I Existing Facility rule. Furthermore, because the reporting requirements differ by source waterbody

ty pe and compliance alternative selected, entities of all sizes have the flexibility to minimize the total compliance costs including the costs and b urden of information collection requirements. 5d. Collection Schedule EPA anticipates that 506 Phase I I existing facilities will fall within the scope of the 316(b) Phase II Existing Facility

rule during the 3 y ears covered by this I CR. Becaus e of the multiple y ears of data that must be collected for the Impingement Mortality and/or Entrainment Characterization Study , the permitting process is anticipated to take up to 3 years to complete. Of the 506 facilities projected to fall within the scop e of this I CR period, 455 will be performing annual monitoring and reporting of operations by the end of y ear 3 of this I CR. The other 51 facilities are operations with recirculating cooling towers applying for a permit but not required to perform annual m onitoring and reporting of operations. Table 2 provides the estimated implementation schedule for the facilities during the I CR approval period.June 2010 25

### 6. Estimating Respondent Burden and Cost of Collection The following sections present the proposed rationale and assumptions made and results of EPA’s estimation of burde n and costs for the implementation of the Section 316(b) Phase I I Existing Facility

rule. Specific respondent activities were detailed in section 4b(ii). It is important to note that this I CR covers y ears 7

– 9 after promulgation of the rule. Therefore, all activities are related to permits renewals and not first

- time permit issuance. 6a. Estimating Respondent Burden This section describes the burden estimates for facilities and Directors, as well as the methods used and assumptions made to deri ve them. Respondent activities are separated into those activities associated with the NPDES permit application and those activities associated with monitoring and reporting after the permit is issued. The reason for this is that the permit cy cle is every 5 y ears, while I CRs must be renewed every 3 y ears. Therefore, the application activities occur only

once per facility

during an I CR period, and so they are considered one

- time burden for the purpose of this I CR. By contrast, the monitoring and reporting ac tivities that occur after issuance of the permit occur on an annual and bi

- annual basis respectively . For estimates of re

permitting burdens, see Exhibits A.1 and A.3 in Appendix A. Facility Burdens In formation collection would require in

- scope facilities to devote time (i.e., as measured by staff hours) and resources (e.g., copies of documents and report mailings) to produce the necessary NPDES permit applications, implementation plans, and bi

- annual status reports. EPA expects that facility

employ ees, inc luding managers, engineers, engineering technicians, statisticians, biologists, biological technicians, draftsmen, and clerical staff, will devote time toward gathering, preparing, and submitting the various documents. To develop representative profiles of each employ ee’s relative contribution, EPA assumed burden estimates that reflect the staffing and expertise ty

pically found in manufacturing facilities and power generating plants. In doing this, EPA considered the time and qualifications necessary to complete a variety

of tasks: reviewing instructions, planning responses, researching data sources, gathering and analy zing data, ty ping or writing the information requested, reviewing results, conferring with permitting authorities and expert consultants, and sending documents.June 2010 26

EPA anticipates that facilities will use contracted services to perform many of their required sampling and analy

zing tasks. The contracted staff are likely to include project managers, biologists, statisticians, and biological technic ians. The work done by these contracted employ ees will be done on

- site on a regular basis. Therefore, the hourly burdens associated with the work are included in the overall burden estimates for each facility

. For each activity

burden assumption, EPA sele cted time estimates to reflect the expected effort necessary to carry out these activities under normal conditions and reasonable labor efficiency rates. EPA assumed that the majority of the actual work performed by facility staff, such as researching, col lecting, and analy zing data, as well as writing the documents, will be carried out by junior technical staff. Burdens associated with managerial and senior engineering staff include time for actions such as occasional or seasonal visits to supervise sampli ng efforts, as well as periodic review of lab results and documentation. EPA assumed that the facilities will employ a drafter to perform computer aided drafting (CAD) operations. For contracted employees, EPA assumed that the majority of the work would be carried out by the biologists and the biological technicians. Table 3 provides a summary of the hourly

burden estimates for facilities performing NPDES permit renewal. Table 4 provides the annual monitoring, and bi

- annual reporting activities associated with the 316(b) Phase I I Existing Facility rule. For a more detailed presentation of hourly burdens for facilities, see Exhibits A.1 and A.2 in Appendix A. The activities listed in the first column of both Tables 3 and 4 correspond to the facility respond ent activities outlined earlier in Section 4b(ii). All facilities will be subject to the start

- up and permit application activities listed in Table 3. For the other listed activities, only a subset of facilities are expected to perform them. The set of act ivities that each facility is estimated to perform is based on the rule requirements to which the facility is subject and the ty

pe of waterbody

from which it draws. For a detailed presentation of the number of facilities performing each activity , see Exhib its A.5 and A.6 in Appendix A.

Start
- Up Activities InTable 3, the start

- up burdens account for reading the published regulations, sample permits, and any guidance materials associated with the rule; determining the required staff and resourc es necessary to successfully

complete the application process and meet all annual monitoring and reporting requirements; and training staff to perform tasks that they would not be required to conduct if the rule were not implemented. It is assumed for the analy sis that facilities will receive their reissued permits at the beginning of the year. Thus, during the first y ear (2010), facilities will perform permit application activities for their permits that are reissued at the beginning of the second y ear (20 11). I t is also assumed that facilities required to conduct Impingement Mortality and Entrainment Characterization Studies will need to begin collecting monitoring data 2 to 3 y ears before permit renewal. Furthermore, all facilities will begin the other pe rmit application activities in the y ear just before receiving their reissued permits. These start

- up activities, applicable to all facilities, are assumed to be performed by facility management and junior technical staff.June 2010 27

* The total does not reflect the average burden for every facility because not all facilities will need to perform every activity listed. Permit Application Activities Permit application activities refer to the development and submittal of the required elements of the a pplication for reissuance of the NPDES permit. As part of the permit application process, all Phase I I existing facilities will gather source water phy sical data, CWI S data, and cooling water sy stem data. EPA anticipates that much of the data required to characterize the waterbody and the CWI S has already been gathered by

the facility , and that much of the actual facility burden is from deriving the requested information from this data. To derive the source water phy sical data, EPA assumes that junior tec hnical staff will work with a CAD operator to develop a description of the phy sical configuration of the source waterbody where the CWI S is located, including areal dimensions, depths, salinity and temperature regimes. The CAD operator will produce scaled drawings showing the phy sical configuration of the source waterbody

and prepare locational maps of the waterbody . The junior technical staff will use this information and available data to produce a report characterizing and documenting the hydrological an d geomorphological features of the source waterbody . Depending on the extent of existing information it might be necessary for some facilities to conduct phy sical studies to determine the intake’s area of influence within the waterbody

.June 2010 28

CWI S data will be used to develop a report on the operation of the intake structure. EPA assumes that a CAD operator will assist junior technical staff in preparing a narrative description of the configuration of the CWI S and its location within the waterbody and in the wat er column, including measurements of the latitude and longitude of the CWI S. In addition, junior technical staff will develop a narrative that describes the operation of the CWI S, including design flows, daily hours of operation, number of day s of the y ear in operation, and seasonal changes, if applicable. Management will review and revise this data. Junior technical staff will also develop a narrative characterizing the facility ’s cooling water sy stem, which includes a flow distribution and water balance diagram for the facility depicting all sources of water to the facility , recirculating flows, and discharges. Management will review and revise this characterization. EPA also anticipates that the junior technical staff will perform engineering calculation s for the source waterbody and CWI S documents. Management will review and revise these calculations.
Inaddition, Phase I I existing facilities need to comply with CDS requirements depending on the compliance alternative selected. Facilities that already h ave a closed

- cycle recirculating sy stem are not required to submit a CDS and facilities that already have a design intake flow of 0.5 ft/s or less are also exempted from impingement requirements. However, facilities choosing to install new technologies rather than reducing flows to levels commensurate with closed

- cycle recirculating sy stems are required to gather and submit additional information in the form of a CDS to confirm that the technology (ies) and operational measures proposed and/or implemented at the intake meet the applicable performance standards. For additional details, see Section 4b(ii). The CDS characterizes impingement mortality and/or entrainment, the operation of the CWI S, and confirms that the technologies and/or operational measures th e facility has selected and/or implemented at the CWI S meet the applicable requirements. The CDS entails a proposal for information collection, source waterbody flow information, an Impingement Mortality and/or Entrainment Characterization Study , technolog y and compliance assessment information, information to support site

- specific determination of BTA for minimizing adverse environmental impact, and a verification monitoring plan. The facility hourly burdens for demonstrating compliance with these requirem ents include developing and submitting narrative descriptions, supporting documentation, and engineering calculations. Comprehensive Demonstration Study (CDS) Requirements Proposal for Information Collection As a first step in the CDS, the fac ility must develop and submit a proposal for the collection of information to support the CDS. EPA assumes that junior technical staff will develop a list and description of any

historical studies characterizing impingement and entrainment and/or the phy si cal and biological conditions in the vicinity of the intakes and their relevancy to the CDS. The facility

management will review the collected information to determine the extent to which existing data are representative of current conditions, are sufficie nt to develop a scientifically valid estimate of impingement and entrainment, and were collected using appropriate qualityJune 2010 29

assurance/quality

control procedures. Junior technical staff are assumed to develop a description of the proposed and/or implemented technologies and operational measures to be evaluated in the CDS. Facility

management will review and revise this description. Although some facilities are likely to have sufficient available information to forego an extensive monitoring study , EPA assume s that all facilities performing a CDS will perform an Impingement Mortality

and/or Entrainment Characterization Study involving between two and three y ears of monitoring. Therefore, these facilities will need to develop and submit a source water sampling plan that documents all methods and quality assurance procedures for sampling and data analy sis, as well as describes the study area (including the area of influence of the CWI S and at least 100 meters beyond). EPA assumes that the junior technical staff w ill review source water and CWI S data. They will use this information to write a draft of the source water sampling plan. A CAD operator will assist the junior technical staff in this effort. The facility manager will supervise this effort, review the draf t, and consult with the manager of the contracted firm that will perform the monitoring. The contracted manager will review the draft and provide feedback. Source Waterbody Flow Information As part of the CDS, facilities with intakes located o n freshwater rivers/streams must submit source waterbody

flow information. This information is used to determine the impact of the CWI S on the natural flow of the source water and is an important factor in determining the appropriate technologies. Similarl y, facilities with intakes on freshwater lakes or reservoirs need to determine the extent to which the CWI S disrupts the thermal stratification of the waterbody

. EPA anticipates that most facilities will have ready access to existing flow and thermal strat ification information. However, EPA assumes that some facilities will need to take flow or thermal stratification measurements immediately around the intake. Junior technical staff are expected to gather existing information and take measurements for freshwater river and stream flows and for lakes and reservoirs. Junior technical staff will perform engineering calculations and develop a report. Facility management will review and revise this information. Impingement Mortality and/or Entrainment Characteriza tion Study The required level of effort for the Impingement Mortality and/or Entrainment Characterization Study is likely to vary considerably

depending on the availability of existing data and the complexity

of the habitat and waterbody in wh ich the CWI S will be located. For the purpose of developing the I CR cost and burden estimates, it is assumed that each existing facility that is required to perform a CDS will also perform the Impingement Mortality and/or Entrainment Characterization Study . EPA assumes that the sampling required for the Impingement Mortality and/or Entrainment Characterization Study will take 2 y ears for facilities drawing from freshwater bodies and 3 y ears for those facilities drawing from marine waters. Therefore, the ent ire application process can take up to 3 y ears to complete. The Impingement Mortality and/or Entrainment Characterization Study activities will be performed in years before the reissuance of the NPDES permit. To accurately

characterize the effects of impi ngement and entrainment on the aquatic communities found in the source water, offshore monitoring must occur at the same time thatJune 2010 30

monitoring for impingement and entrainment is occurring. As a result, EPA assumes that monitoring is performed simultaneously at the facility for impingement and entrainment, and offshore at the edge of the determined zone of influence. Because impingement more often impacts adult organisms, while entrainment affects juvenile organisms, offshore samples must include eggs, juveni le, and adult organisms. Therefore, EPA assumes that three ty pes of sampling will occur, as presented in Table 5.
Table 5. Impingement Mortality and/or Entrainment Characterization Study Sample Types Sample Type Location of Sample Impingemen t sample At the intake structure Entrainment sample Behind the intake screens Offshore sample At the edge of the zone of influence To accurately

characterize seasonal and annual fluctuations in aquatic communities impacted by the CWI S, EPA assumes samp ling is performed at the facility on a biweekly

basis over 2 y ears for freshwater facilities and 3 y ears for marine facilities. EPA believes that a sizable majority of the monitoring work will be carried out by the biologists and biological technicians. Ov er the course of the study , other employ ees will also spend time contributing to the use of the monitoring data. Technology and Compliance Assessment Information EPA assumes that the portion of the Design and Construction Technology Plan (and Technology In stallation and Operation Plan, if applicable) associated with evaluation of potential CWI S effects will be conducted during the year before the issuance of the NPDES permit to allow the facility time to incorporate information from the Impinge ment Mortality and/or Entrainment Characterization Study

already underway

. Design and Construction Technology Plan If the facility

chooses to use design and construction technologies or operational measures in whole or in part to meet the requ irements of § 125.94, the facility must also submit a Design and Construction Technology Plan as part of the CDS. EPA assumes that a CAD operator will delineate the hydraulic zone of influence, that junior technical staff will assist the CAD operator, and management will review this work. Junior technical staff will perform engineering calculations to determine anticipated impingement rates

— and develop narrative descriptions of the design and operation of all design and construction technologies or operatio nal measures (existing and proposed)

— used to meet the requirements to reduce impingement mortality

. Management will review the calculations and write

- up. Those facilities that need to address entrainment will spend approximately the same amount of time per forming engineering calculations and developing a narrative description. Finally , junior technical staff will document that these chosen technologies reflect BTA at the facility ’s site. As part of the Design and Construction Technology Plan, facilities mu st include a site

- specific evaluation of the technology (ies) and/or operational measures. This site

- specific evaluation can be based on representative studies (i.e., studies that have been conducted at CWI Ss located in the same waterbody

ty pe with similar biological characteristics) and/or site

- specific technologyJune 2010 31

prototy pe studies. EPA assumes that for the site

- specific technology prototy pe studies, the facilities will conduct an on

- site pilot study for the technology

or operational measure. Pilot studies were all completed in the first issuance of the permit and therefore the costs are not re

calculated for the renewal phase of the regulation. Information to Support Site
- Specific Determination of BTA for Minimizing Adverse Environmental Impact Facilities may

choose to request a site

- specific determination of BTA in lieu of meeting the performance standards of § 125.94(a). I f a facility requests a site

- specific evaluation of BTA, it will first need to demonstrate to the Director that it meets o ne of two cost criteria. The first of the criteria requires the facility to demonstrate that its cost of compliance with the applicable performance standards specified would be significantly greater than the costs considered by the Administrator. The secon d of the criteria requires a facility to demonstrate that its costs would be significantly

greater than the benefits of complying with the performance standards at the facility ’s site. For the purpose of developing the I CR cost and burden estimates, EPA a ssumed that all respondents requesting a site

- specific determination of BTA would claim that costs outweighed benefits, and therefore would perform the activities associated with the valuation of monetized benefits of reducing impingement and entrainment i n addition to performing the activities associated with the comprehensive cost evaluation study and the site

- specific technology plan. Performing the site

- specific determination is voluntary , so EPA has not included evaluation of the proposed site

- specific measures in developing the I CR cost and burden estimates for facilities. However, for the original I CR developed for the rule, EPA recognized that respondents choosing to perform activities related to site

- specific determination of BTA would incur additio nal I CR costs. I t was estimated that facilities implementing activities related to site

specific determination of BTA, including the preparation of comprehensive, cost

- evaluation study and site

- specific technology plan would incur an average burden of appr oximately 700 hours at a cost of $37,000 per facility (2004 dollars). EPA estimated that the average annual burden increases by

13,754 hours and the total average annual I CR costs might increase between 1 and 1.25 million dollars (2004 dollars) if all faci lities with impingement and entrainment requirements choose to perform activities related to site

- specific determination of BTA and prepare the comprehensive cost evaluation study and site

- specific technology plan. Depending on the number of facilities with both impingement and entrainment requirements choosing to pursue site

- specific determination of BTA, the above I CR burden and cost will be reduced accordingly

. Inaddition, EPA believed that some of the above additional cost will be offset by reductions in technology

costs for these facilities because these facilities may receive lowered performance requirements. Though only

a small percentage of the facilities are expected to perform activities related to site

- specific determination of BTA, EPA estimate d the Director burdens for reviewing site

specific studies for all facilities with impingement and entrainment requirements.June 2010 32

Verification Monitoring Plan As part of the CDS, facilities must include a plan to conduct, at a minimum, 2 years of m onitoring to verify

the full

- scale performance of the proposed or implemented technologies, or operational measures. EPA assumes that the junior technical staff will write a plan that describes the frequency

and duration for monitoring, the locations to be monitored, the basis for determining the locations, and the information that will be included in the final report. A CAD operator will assist the junior technical staff with the drawings and diagrams contained in the plan. The facility

management will ove rsee the writing of the plan and review/revise the various drafts of the plan before it is finalized.
Inthe first 2 y ears of operation under their reissued NPDES permits, Phase I I existing facilities are required to use impingement and entrainment monito ring data to perform verification studies (as described in their verification monitoring plans) to verify the full

- scale performance of the proposed or implemented technologies and/or operational measures. It is assumed that facilities begin verification m onitoring when they receive their permits, monitor for 2 years, and submit the monitoring results and study analy sis at the beginning of the third year. Annual Facility Activities The principal annual activity for most facilities will be biolo gical monitoring. Burden estimates for annual biological monitoring are less than those for the Impingement and Entrainment Characterization Study

performed by

some facilities as part of the permit application process. Biological monitoring is assumed to b e performed at one location on a monthly basis for impingement and on a biweekly basis for entrainment. The monitoring results are analy zed and summarized in a bi

- annual status report. Those facilities that submitted a verification monitoring plan as part of their permit application will also use the first 2 years of monitoring data to produce a verification study . For a more detailed account of the annual burden for facilities, see Exhibit A.2 in Appendix A. Director Burdens The 316(b) Phase I I Existing Facility rule would require Directors to devote time and resources to review and respond to the NPDES permit applications; proposal, study and sampling plans; and bi

- annual status reports submitted to them. Director Permit Issuance Activities EPA expects that State senior technical, junior technical, and clerical staff will devote time toward gathering, preparing, and submitting the various documents. EPA assumed burden estimates that reflect the staffing and expertise used by States for the NPDES permit administration process. In doing this, EPA considered the time and qualifications necessary to complete various tasks such as reviewing submitted documents and supporting materials, verifying data sources, planning responses, determin ing specific permit requirements, writing the actual permit, conferring with facilities and the interested public, and entering the permit information into the PCS/I CI S database. Table 6 provides a summary of the hourly

burden estimates for state Directors performing various activities associated with the 316(b) Phase I IJune 2010 33

* Facilities must monitor for at least 2 years before submitting their verification study for review.
** The total does not reflect the average director burden for each facility because not all facilities will need to perform every activity listed. Cooling Water Intake Structure Requirements The Director must review the Design and Construction Technology Plan to evaluate the suitability and feasibility

of the technology

or operational measures proposed to meet the requirements of § 125.94. For all facilities performing the CDS, the Direct or must review and approve the proposed Verification Monitoring Plan and require that the monitoring continue for a sufficient period of time to demonstrate that the design and construction technology and/or operational measures meet the requirements of § 125.94 (b). For a facility that requests requirements on the basis of site

- specific BTA for minimizing adverse environmental impact, the Director must review the application materials submitted and any other information, including quantitative and qualitat ive benefits that would be relevant to a determination of whether alternative requirements are appropriate for the facility . In determining the Director burden for review of site

- specific determination, it is assumed that all facilities with both impingeme nt and entrainment requirements will choose to pursue the site

- specific alternative. In developing performance requirements for impingement mortality and entrainment for inclusion in a permit, the Director must review information on proposed methods submitted by the facility , evaluate those proposed by

the facility

and other available methods, and specify how compliance with the requirements must be determined including the averaging period for determining the percent reduction required by

the performance s tandards. EPA assumes that the Directors will spend a significant amount of time reviewing the impingement mortality

and entrainment characterization studies and the design and construction technology

plans and Technology

Installation and Operation Plans. A significant amount of review time is also expected for those facilities that choose to request site

- specific determinations of BTA to review the required supporting studies. The additional effort devoted to reviewing the impingement mortality

and entrai nment characterization studies is because the studies cover multiple y ears’ worth of data collected at the site. The additional effort devoted to reviewing the information to support site

- specific determination of BTA is because of the complexity of the re quired comprehensive cost evaluation study or valuation of monetized benefits for reducing impingement and entrainment. Monitoring ConditionsJune 2010 34

Indetermining the applicable monitoring requirements, the Director must consider the facility ’s veri fication monitoring plan and modify the monitoring program on the basis of changes to the phy sical or biological conditions in the vicinity of the CWI S. The requirement for modifying the monitoring program may

be made during the term of the permit or when the permit is reissued. EPA assumes that junior technical staff will review the facility ’s verification monitoring plan and make recommendations for modifying the monitoring program. Senior technical staff will review and implement the recommendations. Rec ord Keeping and Reporting EPA assumes that clerical and junior technical staff will review the monitoring data and status report from the facilities regarding record keeping. Senior technical personnel will oversee their work. Design and Const

ruction Technology Approval For facilities choosing to demonstrate that they have installed and properly operate and maintain a design and construction technology approved in accordance with § 125.99, the Director must review the information s ubmitted to determine if they meet the criteria in § 125.99. EPA assumes that junior technical staff will review the documentation submitted by the facility

for compliance as required in § 125.99. Senior technical staff will provide technical oversight for this work. Moreover, if a person requests approval of a technology under § 125.99(b), the Director must review the information submitted and determine its suitability for widespread use at facilities with similar site conditions in its jurisdiction with m inimal study . The Director must evaluate the adequacy of the technology

when installed in accordance with the required design criteria and site conditions to consistently meet the performance requirements in § 125.94. The Director must approve a technology only following public notice and consideration of comment regarding such approval. EPA assumes that senior technical staff will review the information submitted and evaluate the adequacy

of the proposed technology . Junior technical staff will work under the technical direction of senior personnel in this regard and provide assistance in reviewing and compiling the public comments received. Annual Director Activities Facilities required to perform annual biological monitoring for impingement an d entrainment are required to submit an bi

- annual report that details inspection and maintenance records for impingement and technology controls and a detailed analy sis of monitoring results. EPA assumes that directors will use these reports to track facil ity compliance and to determine if a reduction in monitoring frequency

is appropriate. 6b. Estimating Respondent Costs This section describes cost estimates for facilities and Directors, as well as the methods used to derive them. Because of the 5

- ye ar permit cycle, facilities and Directors will incur initial permitting costs, re

- permitting costs, as well as annual costs. 6b(i). Estimating Labor CostsJune 2010 35

The costs to the respondent facilities associated with the I CR activities can be estimated by multiplying the time spent in each labor category by an appropriately

loaded hourly

wage rate. All base wage rates used for facility labor categories were derived from the Bureau of Labor Statistic’s (BL S) Occupational Outlook Handbook 2010

–2011 . These rep orted labor rates were based on data from the y ear 2009 and are adjusted for inflation. Inflation factor was derived from the BLS Employ

ment Cost Index and was used to adjust the Occupational Outlook Handbook labor rates to reflect labor rates for Septembe r of 2009. Compensatory

loading factors ranging from 35 percent to 53 percent, depending on the labor category , were used to account for any paid leave, supplemental pay , insurance, retirement and savings, and required and nonrequired benefits received by employ ees (EPA I CR 2060.02 citing BLS Employment Cost Trends , March 2001). EPA assumed an additional loading factor of 15 percent to account for general overhead costs directly attributable to facility

employ ees performing work in support of the permit pr ocess. Expenses for contracted employees ty pically include higher overhead costs, as well as a fee to ensure profit for the contracting company . EPA assumes that the overhead for the contracted employees will be 50 percent, and the fee will be 8 percent. To represent the base labor rate for facility management, EPA used the average national salary for an engineering manager of $115,270 per y ear. This figure was divided by 2,080 hours to derive the hourly

managerial wage rate of approximately $55 per hour. After adjusting this rate for inflation, compensation, and overhead, the rate is approximately $98 per hour. The median annual salary

of $48,130 for a mechanical engineering technician was used to represent the base labor rate for junior technical staff. A fter determining the hourly wage rate and adjusting for inflation and other factors, this labor rate was approximately $41 per hour. The median annual salary for a drafter performing CAD work was reported to be $22 per hour, and, after adjusting and loadin g the rate, it is approximately $40. The reported average annual salary for clerical workers was $25,320, and the fully adjusted and loaded hourly rate is approximately

$19 per hour. To represent the base labor rate for a contracted manager of monitoring work done on

- site, EPA used the average national salary for a natural sciences manager of $112,800 per y ear with a fully loaded rate of $122 per hour. The median annual salary for a statistician was $72,610 per y ear with an adjusted hourly

rate of approxim ately

$77 per hour. Biologists and biological technicians had an average hourly

pay of $31 and $18 and a fully loaded rate of $70 and $42, respectively

. Director Labor Costs For Director costs, all the base labor rates and compensation factors were derived from published employ ment cost trends for State and local government workers for the first quarter of 2001 (EPA I CR 2060.02 citing BLS Employment Cost Trends , March 2001). These labor rates were adjusted to reflect labor rates for September o f 2009 ( BLS Employment Cost Index ). EPA chose the BLS labor category

of white

- collar professional specialist to represent the senior administrative and technical staff that will oversee and manage the NPDES permit program. The base hourly

rate for this cat egory

was approximately

$29 per hour, and, after adjusting for compensation and inflation, it is approximately $62 per hour.June 2010 36

Similarly , EPA chose the BLS labor category of white

- collar professional technical to represent the junior technical staff that EP A expects to perform the majority of the actual NPDES permitting work. The reported base pay for this category

was approximately

$18 per hour, which becomes approximately

$37 per hour after being adjusted for compensation, overhead, and inflation. The hour ly

wage for State government clerical workers was $13 per hour before adjustment and approximately $29 afterward. 6b(ii). Estimating Capital and Operation and Maintenance Costs A facility incurs capital/start

- up costs when it purchases equipment or builds structures that are needed for compliance with the rule’s reporting and record keeping requirements and that the facility would not use otherwise. A facility incurs operation and maintenance (O&M) costs when it uses services, materials, or supplies that ar e needed to comply with the rule’s reporting and record keeping requirements and that the facility would not use otherwise. Any costs for the operation and upkeep of capital equipment are considered O&M costs. Another ty pe of O&M cost is for the purchase o f contracted services, such as laboratory analy ses. The purchase of supplies such as filing cabinets and services such as photocopying or boat rental are also considered O&M costs and are referred to as other direct costs (ODCs). Capital and O&M costs were estimated for the active I CR (EPA I CR No. 2060.02) and were simply inflated to September 2009 dollars using CPI

. Ingeneral, the labor costs and O&M costs reported in this analy sis are assumed to represent ty pical average national cost estimates that are likely to be incurred by

Phase I I existing facilities and by permitting authorities. EPA attempted to take into account various factors such as decreases in labor efficiency that occur during extreme climate conditions, equipment down time, and the occasi onal sample that might need to be replaced because it was lost or spoiled during transport. Tables 7, and 8 provide a summary of facility

- level average labor costs, capital costs, and O&M costs over the 3

- ye ar I CR period. For a more detailed presentation o f all compliance costs for facilities, see Exhibits A.1 and A.2 in Appendix A.

Estimating Agency Burden and Costs As mentioned previously , 46 States an d the Virgin I slands are authorized to administer the NPDES permitting program. For in

- scope facilities applying for reissued permits in the 10 unauthorized States and Territories, EPA will incur costs and burdens similar to those incurred by States with p ermitting authority

. 6d. Estimating the Respondent Universe and Total Burden and Costs During the 3 y ears covered by this I CR (which correspond to y ears 7

– 9 after rule promulgation), there are an estimated 506 facilities along with 42 States that the Section 316(b) Phase I I Existing Facility rule could affect. The rule would require each respondent to comply with one or more provisions. In turn, each provision has numerous activities associated with it. Exhibits A.5 and A.6 in Appendix A provid e an estimate of the number of respondents and responses expected for each provision of the rule during each year of the I CR approval period. The annual estimates are based on the compliance schedule used to estimate the cost of the final rule. I n addition , Exhibits A.7 to A.10 provide a summary of the respondent burdens and costs for each y ear of the I CRJune 2010 38

period. These estimates were calculated by multiplying facility

and state Director level burden and cost estimates in Exhibits A.1

- A.3 by the number of re spondents performing each activity in Exhibit A.5 (see Appendix A). 6e. Bottom Line Burden Hours and Costs Tables This section provides a description of bottom line data collection and record keeping burden and cost estimates for implementatio n of the 316(b) Phase I I Existing Facility rule. 6e(i).

6f. Reasons for Change in Burden The current approved I CR for the 316(b) phase I I existing facili ties was developed in 2007. As shown in Table 12, the 2007 I CR estimated an annual average respondent burden of 1,240,599 hours. This I CR estimates an annual average respondent burden of 1,023,521 hours, which represents a 17% decrease in burden. The chan ge in burden results mainly from the shift from the approval period to the renewal period of the 316(b) Phase I I Existing Facilities rule. The previous I CR covered the last 2 y ears of the permit approval period (i.e., years 4 and 5 after implementation) an d the first y ear of the renewal period (i.e., y ear 6 after implementation). This I CR covers renewal of permits only (y ears 7 to 9 after implementation). Activities for renewing an NPDES permit already issued under the 316(b) Phase I I Existing Facilities ru le are less burdensome than those for issuing a permit for the first time.
6g. Burden Statement The annual average reporting and record keeping burden for the collection of information by facilities responding to the Section 316(b) Phase I I E xisting Facility rule is estimated to be 2,071 hours per respondent (i.e., an annual average of 977,293 hours of burden divided among an anticipated annual average of 472 facilities). The state Director reporting and record keeping burden for the review, o versight, and administration of the rule is estimated to average 1,101 hours per respondent (i.e., an annual average of 46,228 hours of burden divided among an anticipated 42 States on average per year). Burden means the total time, effort, or financial r esources expended by persons to generate, maintain, or disclose or provide information to or for a Federal agency . This includes the time needed to review instructions; develop, acquire, install, and use technology and sy stems for the purposes of collectin g, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to comply with any previously

applicable instructions and requirements; train personnel to be able to respo nd to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose information. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of inf ormation unless it display s a currently

valid OMB control number. The OMB control number for EPA’s regulations are listed at 40 CFR Part 9 and 48 CFR Chapter 15. To comment on EPA’s need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including the use of automated collection techniques, the Agency has established a public docket for this I CR under Docket I D No. EPA
