==Dear Sir or Madam:==

In accordance with Michigan Department of Environment, Great Lakes, and Energy (EGLE)
Authorization to Discharge under NPDES Permit No. MI0037028 (the Permit), the DTE Electric Company (the Company) is submitting the attached application for the reissuance of the Permit. The associated $750.00 application fee will be paid online at the time of the submittal of the application.
Comments Regarding the Application on MiWaters
* Outfall Information and Effluent Characteristics:
o   Outfall 001 and Outfall 009 - Laboratory analyses including PFAS for the discharge from these two outfalls are pending. Due to the plant's refueling outage, representative samples from Outfall 001 and Outfall 009 have not yet been collected. They will be obtained and analyzed as soon as possible in 2022, and the results will be submitted to EGLE when they become available, in support of this application. Ms. Christine Aiello with EGLES's Water Resources Division agreed with this approach, during a verbal communication dating February 2, 2022.
o   Outfall 011 and Outfall 013 - For these two outfalls the Company requests a waiver for reasons included in Attachment 6 and Attachment 7 respectively.
included waiver request
* Part I.A.2.b. of the Permit states: "On or before April 4, 2022, with the application for reissuance, the permittee shall submit any revisions to its procedure entitled "Fermi 2 Zebra Mussel Control Using CT-1300," dated March 29, 2018, or if no such revisions have been made, the permittee shall submit a written statement certifying to this.'~ The Company confirms through this letter that the Zebra Mussel Control Using CT-1300 procedure has not changed, and Fermi 2 Power Plant continues to follow the procedure dated March 29, 2018.
* On August 19, 2020 the Company requested a reduced monitoring frequency for Total Copper and Total Phosphorous at Monitoring Point (MP) 001A in accordance with Part I.A.Le and Part I.A.1.f of the Permit. EGLE Water Resource Division approved the request on September 22, 2020, reducing the monitoring from monthly

DTE Electric - Fermi 2 Nuclear Power Plant NPDES Permit NO. MI0037028 Renewal Application April 4, 2022 to quarterly. Samples collected from 2018 to date from MP 001A and MP 009A are well below the permit limits, as indicated in the tables included in Attachment 10. We use this permit renewal application to request the removal of monitoring requirements for Total Copper and Total Phosphorous at MP 001A and MP 009A.

COOLING WATER INTAKE STRUCTURES The withdrawal of cooling water removes and kills hundreds of billions of aquatic organisms from waters of the United States each year, including fish, shellfish, fish eggs, and larvae. Aquatic organisms drawn through cooling water intake structures (CWIS) are either impinged (I) against components of the intake structure or get drawn into or entrained (E) in the cooling water system itself. Most impacts are to the early life stages of aquatic organisms. Due to the adverse environmental impact of I and E on aquatic organisms, USEPA has promulgated rules under section 316(b) of the Clean Water Act to set national performance standards to minimize the mortality of aquatic organisms from I and E for new and existing industrial facilities.
Section 316(b) requires that the location, design, construction, and capacity of CWISs reflect the best technology available (BTA) for minimizing adverse environmental impacts (I and E). All new or existing facilities utilizing a surface water intake structure to provide cooling water shall submit information for review as specified below. Please complete the following questions, compile the requested information, and submit the information as an attachment to this Application.
The rules and reguirements referenced below can be accessed at httP-s://www.michigan.gov/eglenP-des. Under the Information banner, click on 316(.Q) Cooling Water Intake Structure Guidance.
Does or will the intake structure have a design intake flow (DIF) rate (instantaneous maximum) greater than 2 MGD AND does or will the facility use at least twenty-five percent of water withdrawn exclusively for cooling purposes?
YES In accordance with the Final Rules promulgated by USEPA under 316(b) and effective October 14, 2014, existing facilities (including those utilizing a closed-cycle recirculating cooling system) shall submit the information specified in 40 CFR 122.21(r)(2), (3), (4), (5), (6), (7), and (8).
Does this facility have an Alf greater than 125 MGD?
NO Does this facility have a 'new unit' as defined under 40 CFR 125.92(u)? A 'new unit' may have its own dedicated cooling water intake structure, or the new unit may use an existing or modified cooling water intake structure.
NO Attach all information required above for your facility.

DTE Electric - Fermi 2 Nuclear Power Plant NPDES Permit N0. MI0037028 Renewal Application April 4, 2022 Narrative Description Fermi 2 Power Plant is a 1,170-megawatt electric General Electric Boiling Water Reactor 4 Nuclear Power Plant. The Fermi 2 power block is situated in the Northeast Quarter of a 1,120-acre site that is located approximately 8 miles east-northeast of Monroe, Michigan.
The water sources for the Fermi 2 Power Plant are municipal water supplied by Frenchtown Township water and lake water withdrawn from Lake Erie.
Water discharges from the plant as a result of electric power generation and support processes include: cooling tower blowdown, reverse osmosis wastes, chemical and non-chemical metal cleaning wastes, processed radwaste water, low volume wastes, storm water runoff, treated oily wastewater, intake and strainer backwash water, firefighting system pressurization water, settled water from dredge material storage, and sanitary waste water.
Cooling tower blowdown, residual heat removal system service water, chemical and non-chemical metal cleaning wastes, and processed radwaste water are permitted to discharge from Outfall 001 to Lake Erie.
Storm water runoff, low volume wastes, and chemical and non-chemical metal cleaning wastes are permitted to discharge from Outfall 009 to Lake Erie via Swan Creek.
Treated oily waste water, firefighting system pressurization water, intake screen and strainer backwash water, storm water, and General Service Water Flow Control are permitted to discharge from Outfall 011 to Lake Erie via Swan Creek.
Settled water from the dredge material storage basin is permitted to discharge from Outfall 013 to Lake Erie.
Sanitary wastewater is composed of treated oily waste water, oil/water separator discharge water and plant domestic waste. This waste is collected in a holding tank and forwarded to the City of Monroe Municipal Waste Water Treatment Plant for treatment and disposal.

MI0037028 Renewal Application April 4, 2022 Attachment 6 - Fermi 2 2022 Outfall 011 Laboratory Analyses Request for Waiver The Company requests a waiver for submittal of analytical data from the Fermi 2 Power Plant 011 for the following reasons:
* Monitoring is required at Outfall 011 only during times of oily wastewater discharge. This effluent has been re-routed to the Monroe Metropolitan Water Pollution Control Facility via Permit No. 1020 (City of Monroe).
* The company retains the option to discharge via Outfall 011 if at any time discharge to the City of Monroe is no longer permitted. At that time, the company will notify the MDEQ and arrange to submit the required analytical information, to be obtained upon commencement of discharge via Outfall 011.

* Monitoring is required at Outfall 013 only during the infrequent discharge of dredged material effluent. The water treatment additives that enhance settling are previously approved and do not require separate monitoring.
* Total suspended solids (TSS) is the only parameter of concern for this monitoring point. This data is submitted as required during times of discharge on the electronic Discharge Monitoring Reports (eDMRs). There are no process wastewaters that are discharged via this monitoring point.

RE: Water Treatment Additive (WTA) Response; DECO-Fermi-2 Plt; MI0037028 Hi Nick, I wanted to get back to you regarding your phone calls on May 20 and 27, 2014. Depositrol BL5400 was previously approved at a lower discharge concentration (2 mg/L) with no total phosphorus monitoring (November 22, 2000, approval), and Depositrol BL5400 was recently approved at an increased discharge concentration (5.12 mg/L) with a condition to conduct total phosphorus monitoring (May 1, 2014 approval, below). You wanted to know if DECO needed to conduct the total phosphorus monitoring if Depositrol BL5400 was discharged at the lower concentration.
If DECO-Fermi-2 Plt discharges Depositrol BL5400 at any discharge concentration greater than 2 mg/L then total phosphorus monitoring must be conducted according to the May 1, 2014, approval. Please note that the approved maximum discharge concentration of Depositrol BL5400 is 5.12 mg/L.

==SUBJECT:==
Water Treatment Additive (WTA) Response DECO-Fermi-2 Plt MI0037028 We have reviewed your April 9, 2014, request and subsequent information provided on April 10, 2014, to increase the discharge concentration of Depositrol BL5400 from Outfall 001.
Outfall 001 has a maximum design flow of 45.1 million gallons per day and discharges to Lake Erie. The product is proposed to be used as a deposit control and scale inhibitor.
The discharge of Depositrol BL5400 from Outfall 001 was previously approved on November 22, 2000, at a maximum discharge concentration of 2 milligrams per liter (mg/L). According to your April 9, 2014 request, you are requesting to increase the discharge concentration of Depositrol BL5400 from 2 mg/L to 5.12 mg/L.
We approve the use of Depositrol BL5400 at the expected discharge concentration of 5.12 mg/L. However, this approval is contingent upon the following:
l  According to the Material Safety Data Sheet (MSDS), the product Depositrol BL5400 contains phosphorus. Therefore, total phosphorus monitoring of the Outfall 001 effluent should be conducted.
l  Total phosphorus monitoring should be conducted weekly, during periods of the discharge of water treated with Depositrol BL5400.
l  Grab samples should be collected for total phosphorus monitoring.
l  Test procedures for the analysis of total phosphorus should conform to regulations promulgated pursuant to Section 304(h) of the Federal Act (40 CFR http://arbm09.dteco.com/mail/u01206.nsf/418d873877f54ab185257d01003be859/F8861498... 3/1/2017

Page 3 of 3 Part 136 - Guidelines Establishing Test Procedures for the Analysis of Pollutants).
l  The results of each test should be submitted electronically (e.g. email format) to the Jackson District Office, WRD, within 30 days after completion of each test.
l  The total phosphorus test results will be evaluated during permit re-issuance, and the re-issued permit may include a total phosphorus effluent limitation based on the continued use of Depositrol BL5400.
Approval is based on requested discharge concentrations and frequency. Any increased use from the proposed amount will require further review by the department.
If you have any questions regarding this decision, please contact me at 517-284-5586.
Please consider this note to be our formal correspondence on this matter and keep a copy for your records. If you would like this information in another format, please contact me.

[EXTERNAL] WTA Response - MI0037028 - FLOGARD* MS6201 - January 19, 2022

==Dear Marcela:==

We have reviewed your January 11, 2022 water treatment additive request to use FLOGARD* MS6201 manufactured by SUEZ WTS USA at the DECO-Fermi-2 Plt facility located in Newport, Michigan. FLOGARD*
MS6201 is proposed to be used continuously as a scale/corrosion inhibitor and has the potential to be discharged from Outfall 001.
The facility is authorized under NPDES Permit Number MI0037028 to continuously discharge a maximum of 45.1 million gallons per day (MGD) of cooling tower blowdown, processed radwaste wastewater, residual heat removal system service water, and treated chemical and nonchemical metal cleaning wastewater from Monitoring Point 001A through Outfall 001. Outfall 001 discharges to Lake Erie at 41.96485, Longitude -
83.25448.
Below is the water treatment additive requested, the proposed function, the requested dosage and discharge concentration in micrograms per liter (g/l), and our decision (Table 1).
TABLE 1. Product proposed to be discharged from Outfall 001.
Discharge Product        Outfall       Dosage Product                                                    Concentration          Decision Function                    Rate (g/l)

FLOGARD*        Scale/corrosion    Outfall 40,000 g/l       2,000 g/l         Approved MS6201            inhibitor        001 FLOGARD* MS6201 The dosage rate provided is the combined dosage from RHRSW DIV I and RHRSW DIV II. We approve the use and discharge of FLOGARD* MS6201 as the proposed discharge concentration of 2,000 ug/l indicates there is not a reasonable potential for FLOGARD* MS6201 to be discharged at concentrations exceeding Michigan Water Quality Standards (WQS). This product also contains Phosphorus. Approval of this product is also contingent upon compliance with the limits and monitoring requirements for Total Phosphorus in the current NPDES permit.
Approval is based on the requested dosage rate, discharge concentration, frequency, and SDS. Any change in the product composition, product name, use, and/or facility operation from those proposed will require further review by the department.
Please consider this note to be our formal correspondence on this matter and keep a copy for your records. If you have any questions regarding this decision or would like additional information, please contact me at 517-282-9804.

==SUBJECT:==
Water Treatment Additive (WTA) Response DECO-Fermi-2 Plt MI0037028 We have reviewed the additional information you provided on June 11, 2014, regarding the WTA Spectrus NX1102. Spectrus NX1102 was approved on June 10, 2014, for discharge from Outfall 001.
The June 10, 2014, approval states that the proposed discharge concentration of 3.75 &#xb5;g/L http://arbm09.dteco.com/mail/u01206.nsf/418d873877f54ab185257d01003be859/D8A01F9... 3/1/2017

Page 2 of 2 for Spectrus NX1102 is based on a dosing concentration of 20 milligrams per liter (mg/L) in the Residual Heat Removal Service Water (RHRSW) system reservoir, a half-life of 70 hours, and a hold-time of 20.4 days before discharge.
However, according to the additional information you provided, the length of a half-life varies based upon the temperature and pH in the RHRSW reservoir. And, the half-life of 70 hours is based on the temperature and pH in the RHRSW reservoir in the winter months, which is not the seasonal time frame when Specturs NX1102 will be used. Under normal operating conditions when Spectrus NX1102 will be used, the length of a half-life will be approximately 2 - 12 hours.
Therefore, we are revising our June 10, 2014, approval to discharge Spectrus NX1102 to the following: We approve the discharge of Spectrus NX1102 at the proposed discharge concentration of 3.75 &#xb5;g/L.

 & APPLICABILITY [122.21(R)(1)]
1.1      Fermi 2 Power Plant Description The Fermi 2 Power Plant is located on the western shore of Lake Erie, approximately 8 miles northeast of Monroe, MI, and 28 miles southwest of Detroit. The plant is located in Frenchtown Township, Monroe County, Michigan. Fermi 2 is a single-cycle, forced-circulation boiling water reactor (GE-BWR 4) with a 1,170 MWe (3,486 MWt) generating capacity, and is cooled using a closed-cycle condenser cooling-water system. The Plant is comprised of the reactor, the turbine, the 120-kV and 345-kV switchyards, a residual heat removal (RHR) complex, two natural-draft hyperbolic circulating water cooling towers, a general service water system (GSWS) pump house, a circulating water pump house, a circulating water reservoir (CWR), an independent spent fuel storage installation (ISFSI), auxiliary radwaste and office buildings.
Source water for the GSWS, which provides both makeup cooling water for the CWR and water for other plant systems, is withdrawn from Lake Erie via intake canal and intake structure. The GSW S consists of the following: two sluice gates, five GSW pumps; two CWR makeup pumps; five strainers on the discharge of the GSW pumps; and two traveling screens. The site for the Fermi 2 Power Plant also includes the Fermi 1 Power Plant, decommissioned in 1975.
1.2      Existing Facilities [122.21(r)(1)(ii)(A)
The Fermi 2 Power Plant is considered an existing facility as defined at 40 CFR 125.92(k).
1.3      Greater Than 125 MGD AIF [122.21(r)(1)(ii)(B)
Water withdrawn for the General Service Water System at the Fermi 2 Power Plant is provided by an intake structure with a maximum design intake flow (DIF) of 65,000 gallons per minute, equivalent to 93.6 million gallons per day. The average actual intake flow (AIF) over three years (2010-2012) is 37,000 gallons per minute, or 54.0 MGD. The Fermi 2 Power Plant is not an existing facility with greater than 125 MGD actual intake flow.

2.1      Source Water Body Descriptions [122.21(r)(2)(i)]
Source water for the Fermi 2 Power Plant GSWS is drawn from the western basin of Lake Erie via a concrete intake canal. The intake canal is located at the end of a 700-ft long by 300-ft wide intake channel located 6.3 miles northeast of the mouth of the River Raisin and 6.3 miles southwest of the mouth of the Detroit River (NOAA, 1976). The location of the facility in reference to the source water and other physiographic features, along with a general canal layout, is provided in Figures 2.1 and 2.2, 2.1.1    Physical Configuration of Source Water Bodies Lake Erie is the fourth largest Great Lake, with a surface area of approximately 9,910 square miles (mi 2),
and an average and maximum depth of 62 and 210 feet (ft), respectively. (EPA and Government of Canada, 1995). The Detroit and Maumee Rivers, flowing into western part of the lake, supply the majority of the water to the lake, while the Niagara River and the Welland Canal, located in the northeast corner, provide an outlet to Lake Ontario (Wilcox et al., 2007). Lake Eries outflow, on average 210,000 cfs, is by wind direction, lake ice and seasonal aquatic plant growth found on the Niagara River (Neff and Nicholas, 2005). The lake is generally split into three distinct basins; western, central and eastern, with the western basin being the shallowest (~24 ft). At the entrance to the Plant intake canal, the Lake is 5-7 feet deep (dredged channel). With the exception of the canal, typical lake depths near the plant shoreline decrease from one to nineteen feet over two miles, going east.
2.1.2    Water Quality Parameters Water temperature at the intake of the Fermi 2 Power Plant ranges from 37 to 78 &deg;F (based on monthly averages using data collected from 2010-201). Table 2.1 and Figure 2.3 provide detailed temporal water quality data for 2010-2012 at the intake. During a 2008-2009 sampling of water just east of the intake
(~1500 ft), average specific conductivity was measured as 336 &#xb5;S/cm, with seasonal variation measured between 276 &#xb5;S/cm in October and 411 &#xb5;S/cm in April (AECOM, 2009a).
2.2      Water Body Hydrologic and Geomorphic features [122.21(r)(2)(ii)]
2.2.1    Lake Erie Hydrology The volume of Lake Erie is approximately 116 cubic miles, or roughly 128 trillion gallons. About 80 percent of Lake Erie's total inflow comes from the Detroit River, which connects Lakes St. Clair and Erie.
The remaining inflow comes from precipitation and other connected watersheds. Annual average rainfall over Lake Erie is about 35 inches per year and contributes an estimated 25,497 cubic feet per second (cfs), while runoff is estimated to be 21,189 cfs. Inflow from the Detroit River is estimated to be 188,333 cfs, and the outflow to Lake Ontario is estimated to be 206,202 cfs. The average annual evaporation from Lake Erie is estimated to be 36 inches per year and removes approximately 26,027 cfs from the water balance (NRC, 2013). Between 2006 and 2010, the total combined average water use in the basin was 56,170 million gallons per day (MGD) or about 20,502 billion gallons per year (DTE, 2013).
Flow velocity on Lake Erie varies due to wind currents and seasonal climate variations and has been previously measured as 0.4 fps (average) in the western basin and 0.3 fps between the Detroit River and the City of Toledo municipal water intake (NRC, 2013).
Water levels on Lake Erie are typically higher in the spring and summer and lower in the fall and winter.
The record low water elevation of Lake Erie at the DTE Fermi water level gauge (ID 9063090) is 563.65 feet (NAVD88), occurring on February 16, 1967 (NRC, 2013); while the highest is 576.22 feet (NAVD88),
occurring on April 9, 1998 (NOAA). On average, the lake level is at 571.6 feet (NAVD88). The typical wind current pattern for the western basin is west to east. Winds blowing across the lake can cause lake level increases in down-wind sectors and subsequent oscillations of water levels in response to these atmospheric conditions, or seiches. The U.S. Army Corps of Engineers (USACE) estimates that the maximum 100-year storm-induced surge on Lake Erie is 3.9 feet at the Fermi site. The maximum-recorded rise (1941-1981) was 6.3 feet and the maximum-recorded fall was 8.9 feet (NRC, 2013).

The facility has a shore barrier, located on the plant's eastern boundary along Lake Erie. The barrier consist of a rubble-mound structure with an armor cover of stone, with a toe elevation of 572.0 feet, a crest elevation of 583.0 feet, and a lake-ward side slope of 2:1 (horizontal to vertical). The purpose of the barrier is to protect the shoreline adjacent to the plant from erosion resulting from wave action and preserve protect the main plant against wave forces and flood conditions.

Tetra Tech, Inc.                                                                                         2.2.2 Determination of the Fermi 2 Power Plant Intake Area of Influence 2.2.2.1 Approach The Area of Influence, also referred to as the Hydraulic Zone of Influence (HZI) or "zone of potential involvement" (EPA, 1977), is the portion of a source water body hydraulically affected by the withdrawal of source water by an intake structure. Outside of the HZI, water flow is not influenced by the intake structure, but is driven by ambient and/or wind-induced factors. The radial distance from the intake structure to the line defining the boundary of the HZI (the RHZI) is determined by continuity calculations.
The maximum radial distance to the stagnation point limit (HZI-line) is determined using potential flow theory. The calculation incorporates a variety of variables. Appendix A provides a detailed summary of the procedure and calculations used for the determination of the HZ-line at the Fermi 2 Power Plant.
2.2.2.2 Results The input values and the calculated dimensions of the HZI for the intake structure located on Lake Erie near the shoreline are shown in Table 2.2. HZI-lines were calculated for two average ambient velocity (Vma) conditions at the maximum Design Intake Flow (DIF).
The two ambient average velocity conditions [direction?] in Lake Erie include:
Low ambient average velocity (Vma) of 0.1 ft/s High ambient average velocity (Vma) of 0.3 ft/s The maximum design intake flow condition:
Maximum Daily Average Design Intake Flow (93.6 MGD or 144.8 cfs)
The maximum RHZI value based on low average ambient velocity (Vma=0.1 ft/s) is 76.8 ft. Under high ambient average velocity conditions (Vma=0.3 ft/s), the HZI will decrease and the HZI-line will move closer to the shoreline. The minimum RHZI value based on a high average ambient velocity is 25.6 ft. Figure 2.4 provides locations of the HZI-line in relation to intake structure.

Tetra Tech, Inc.                                                                                         3.0      COOLING WATER INTAKE STRUCTURE DATA [122.21(r)(3)]
3.1      Configuration [122.21(r)(3)(i)]
3.1.1    General The intake structure for the Fermi 2 Power Plant General Service Water System (GSWS) is located in a constructed intake channel withdrawing water from Lake Erie. The channel is roughly 5-7 ft deep, 775 ft long and 275 wide, and is protected by breaker walls on the north and south side. The intake canal is located in the northwest corner of the channel and is a 33 -ft. wide by 22.5-ft. high concrete canal, with a bottom elevation of 560.0-ft. With an average Lake Erie water level of 572.5-ft., the intake canal has an average depth of 12.5-ft. The canal is oriented north-south and runs approximately 61 feet to a submerged opening in the GSW pump house. The final 25-ft. of the canal is separated into two 15.5 feet wide channels. Each intake canal passes through a trash rack and a traveling screen, and enters the GSW pump pit. The five GSW pumps take water from the intake pit and discharge the water into a common header. The once-through GSW discharges into the station's Circulating Water System. The ensuing sections consider the various components of the GSWS intake structure in detail. A generalized diagram of the Circulating Water System, along with detailed drawings of the intake are provided in Figures 3.1 to 3.3.
3.1.2    Trash Rack Upon entering the GSW pump house through the two submerged intake openings, water passes through two large, stationary, steel bar trash racks (3-in. clear opening). Trash racks are cleared of debris by a pivoted steel rake. The rake slides down the racks in steel channel guides and is pulled back up again by steel cables connected to electrically driven hoisting machinery. Debris is removed by lowering the rake in the open position and lifting the closed rake to collect debris. Debris are collected in a cart that is removed from the trash rack assembly and appropriately emptied and contents disposed of offsite 3.1.3    Traveling Screens After passing through the trash racks, the water enters two separate screen bays measuring 11.75-ft. in width. A conventional vertical traveling screen is located at the mid-point of each bay. The two traveling screens consist of a series of flat wire woven screens with a 0.375-inch weave mounted on two strands of endless roller chains. The mesh porosity is approximately 70% assuming the wire is 0.080 inch diameter.
The roller chains are rotated by a sprocket wheel driven by a two-speed motor. The traveling screens can be operated in either automatic or manual mode. Warm water from the GSW discharge header can be supplied to the traveling screens to prevent icing.
3.1.4    GSW Traveling Screen Backwash A backwash system is used to remove the debris from the traveling screens. The GSW discharge header provides high pressure water to each of the two traveling screens for backwashing. After filtering through a small screen, the backwash is directed back to the GSW pits upstream of the main traveling screens.
An auger system removes the debris from the backwash screen and deposits it in a local collection container, which is manually emptied. The backwash screen also filters the water from the GSW pump strainers. Backwash is returned to the pump pit, where it can be treated with chemicals.
3.1.5    GSW Water Pumps After passing through the traveling screens, the water then enters the GSW pump pit. Sluice gates can be used to isolate the GSW pump pit from the channel providing source water. The GSW water pumps withdraw water from the pump pit. The five GSW pump assemblies are vertical, motor-driven centrifugal pumps each with a capacity of 7,000 gpm. Additionally two make up water pumps are present and each operate at a capacity of 15,000 gpm. The maximum design intake flow for the Fermi 2 Power Plant is 65,000 gpm, or 93.6 MGD. During cooler months, fewer circulating water pumps are operated to maintain the cooling efficiency and meet the thermal discharge limits.

Strainers are located on the GSW water pump discharge in order to remove any remaining debris and to prevent fouling of the heat transfer surfaces during continuous loads. The strainers can be controlled locally or function automatically on high differential pressure across the strainer.
3.2      Latitude and Longitude [122.21(r)(3)(ii)]
The GSW pump house is located at 41&deg; 57 38 N, 83&deg; 15 23 W (NAD1983).
3.3      Operation of Cooling Water Intake Structure [122.21(r)(3)(iii)]
The GSWS is used to both provide intermittent and continuous flow to various plant systems. Continuous flow is provided for the main generator hydrogen and main turbine lube oil coolers, the reactor and turbine building closed cooling water systems, and to provide flow to the biocide injection system. Intermittent flow is also provided to the auxiliary boiler house, traveling backwash system, fire protection system, the lawn sprinkling system and the residual heat removal complex. The continuous flow discharge from the GSW fed systems is used for makeup water in the circulating water reservoir.
Operation of the intake structure varies seasonally. During normal plant operating conditions, one to five circulating water pumps are in operation depending upon plant heat load and weather conditions. Two GSW pumps are typically in service with three in standby in winter months, and four GSW pumps are typically in service with one in standby in summer months. Only one makeup water pump is utilized at a time.
The GSW intake structure is designed for operation during low lake levels (i.e., less than a Lake Erie elevation of 568 feet). During such an event, source water can be supplied from the Circulating Water Reservoir (CWR) by closing the sluice gates between the GSW pit and the channel, and opening a valve connecting a 54-inch line between the CWR and the GSW pump intake pit. The GSW and circulating water systems can be operated for a limited period of time in this mode to support plant load reduction and shutdown. (Fermi 2012a, Section 9.2.1.3).
The maximum design intake flow for the Fermi 2 Power Plant is 65,000 gpm, or 93.6 MGD, representing
<0.001% of the available total Lake Erie volume. Figure 3.4 provides the monthly actual intake withdrawal data and for a period of three years (2010-2012).

[122.21(r)(4)]
The aquatic ecosystem surrounding the Fermi 2 Power Plant is characterized by waters of the western basin of Lake Erie. A total of 170 fish species occur in the Great Lakes and approximately 23 species occur at the Fermi 2 Power Plant. This section includes the required information to meet 122.21(r)(4) (i) through (xii).
4.1      List of Data Not Available and Efforts to Identify Sources [(r)(4)(i)]
All required data to support the source water baseline biological characterization used to meet r(4)(i) is available through existing studies and reports, as summarized throughout this section.
4.2      List of Species/Taxa and Life Stages and Their Relative Abundance in the Vicinity of the Cooling Water Intake Structure [(r)(4)(ii)] and Those Species and Life Stages Most Susceptible to Impingement and Entrainment [(r)(4)(iii)]
4.2.1    Fermi 2 Power Plant Characterization Lawler, Matusky & Skelly Engineers (LM&S, 1993) conducted an IM&E study at the Fermi 2 Power Plant general service water (GSW) pumphouse for 12 months from 1 October 1991 to 30 September 1992.
There were 23 fish species/taxa collected during the study period. Species diversity was greater in impingement samples than entrainment samples: 23 versus 15 taxa, respectively. Fifteen taxa identified to the species level were found in both entrainment and impingement samples (LM&S, 1993). An impingement and entrainment study was also conducted from August 2008 through July 2009 at the Fermi 2 GSW pump house (AECOM, 2009b). A total of 19 taxa were collected during the study period.
Species diversity was greater in impingement samples than entrainment samples: 15 versus 13 taxa, respectively. Tables 4.1 through 4.5 present estimated abundances of fish species and the life stages susceptible to impingement and entrainment.
The total actual number of fishes impinged during the 1991-1992 study was 1,239, with biomass totaling 26.654 kg. Gizzard shad was the most abundant species collected (n = 833; 67.2%) followed by white perch (n = 95; 7.7%), rock bass (n = 57; 4.6%), freshwater drum (n = 46; 3.7%) and emerald shiner (n =
44; 3.6%). Gizzard shad also comprised the majority of fish biomass impinged (19.023 kg; 66.4%),
followed by freshwater drum (4.759 kg; 16.6%), goldfish (1.019 kg; 3.6%), rock bass (0.797 kg; 2.8%),
and white perch (0.562 kg; 2.0%). Total daily impingement remained relatively low throughout the sampling period, with the exception of peak impingement in February and March 1992. The majority of total numerical abundance occurred in February 1992 and the majority of biomass impingement abundance occurred in March 1992.
Estimated annual fish impingement based on weekly impingement rates over the 12-month study (1991-1992) totaled 13,699, with biomass totaling 329.758 kg. Gizzard shad remained the most numerically abundant species collected (n = 9,798; 71.5%), followed by white perch (n = 926; 6.8%), rock bass (n =
461; 3.4%), freshwater drum (n = 430; 3.1%) and emerald shiner (n = 424; 3.1%). Gizzard shad comprised the majority of fish biomass impinged (229.541 kg; 69.6%), followed by freshwater drum (42.491 kg; 12.9%), goldfish (18.437 kg; 5.6%), rock bass (6.332 kg; 1.9%), and white perch (5.693 kg; 1.7%).
A total of 11 impingement sample events occurred during the 2008/2009 study at the Fermi 2 GSW pump house. Total actual number of fishes impinged during the study was 101. Gizzard shad accounted for the majority of the collection (n = 39; 38.6%), followed by emerald shiner (n = 29; 28.7%), and white perch (n=10; 9.9%). Peak impingement occurred in December 2008. Estimated annual impingement numbers collected at the Fermi 2 operational capacity of 67,208,472 m3 over 12 months (average of 37,000 gpm) was 3,102 fishes (Table 4.4). Gizzard shad was the most abundant species (n = 1,204; 38.8%).
Estimated monthly entrainment during post traveling screen collections over the 12-month 1991-1992 study would total 13,547 fishes. The most numerically abundant larval fish species were gizzard shad (n

Peak monthly numbers of organisms entrained occurred in June 1992. A majority of numerical abundance was collected at location S1 (see section 4.7.2 for explanation of data analysis).
Actual entrainment during intake canal entrainment collections over the 12-month study totaled 23,917 fishes. Larval and juvenile fish were the most numerically dominant life stages collected (n = 23,379; 97.8%). The most numerically abundant larval and juvenile fish species were gizzard shad (n =5,955; 25.5%), Cyprinidae (n= 5,026; 21.5%), Morone spp. (n = 3,967; 17.0%), and white perch (n = 1,434, 6.1%). Unidentified species accounted for 12.1% (n = 2,838) of larvae abundance. Eggs accounted for 2.2% (n = 538) of the collection. The most numerically abundant fish egg taxa identified were Cyprinidae (n = 202; 37.5%), Percidae (n = 137; 25.5%), trout-perch (n = 101; 18.8%), and Morone spp. (n = 97; 18.0%).
Estimated annual entrainment, based on intake canal entrainment collections over the 12-month study, totaled 2,945,693. Fish larvae and juveniles were the most numerically entrained life-stages (n =
2,883,326; 97.9%) followed by fish eggs (n = 62,367; 2.1%). The most numerically abundant larval and juvenile fish species were Cyprinidae (n =659,985; 22.9%), Morone spp. (n= 577,319; 20.0%), gizzard shad (n = 560,816; 19.5%), and Clupeidae (n = 252,487, 8.8%). Unidentified larval and juvenile species accounted for 12.7% (n = 364,764) of larvae and juvenile abundance. The most numerically abundant fish egg taxa identified were Cyprinidae (n = 30,444; 48.8%), Percidae (n = 16,198; 26.0%), and Morone spp.
(n = 1,966; 3.2%). Twenty other taxa accounted for 21.8% (n = 13,607) of estimated fish egg entrainment.
A total of 13 entrainment sampling events occurred at the Fermi 2 GSW pumphouse during the 2008/2009 study. The actual number of entrained fish collected was 1,286. Larval fishes accounted for the large majority of the collection (n = 1,205; 93.7%) followed by eggs (n = 81; 6.3%). Gizzard shad accounted for the majority of the larval fishes collected (n = 475; 39.4%), followed by emerald shiner (n =
233; 19.3%), and bluntnose minnow (n = 178; 14.8%) (Table 4.5). A large majority of eggs collected were not identifiable (n = 74; 91.4%). Peak entrainment occurred in July 2009. Estimated annual entrainment numbers collected at the operational volume of 61,151,056 m3 over 10 months (average of 37,000 gpm) at Fermi 2 for larvae and eggs combined was 62,566,648. Gizzard shad remained the most abundant species collected (n = 30,238,133; 48.3%) (Table 4.5).
Gizzard shad impingement accounted for a majority of both numerical abundance and biomass, with all the other species comprising a very small percentage (<10%) of the total estimate. However, since gizzard shad are considered a fragile species under the 316(b) rule, they would be excluded from the calculation of overall impingement mortality for the remaining species. Abundances without gizzard shad are presented in Table 4.1.
The recreational sport fish species impinged and/or entrained at the Fermi 2 Power Plant include black crappie, bluegill, channel catfish, largemouth bass, pumpkinseed, rock bass, walleye, white bass, white crappie, white perch, and yellow perch. Two additional recreational sport fish taxa were identifiable at the genus level (Lepomis spp. and Pomoxis spp.), likely because of ambiguous developmental features that make differentiation between species difficult at entrainable life stages. These recreational sportfish combined represent 17.5% of the total number impinged and 28% of annual Larval and Juvenile fish entrained at the Fermi 2 Power Plant, based on the 1991-1992 study. The white perch, a non-native species that recently colonized the Great Lakes, is considered harmful to some native fish communities.

However, in 2013 only three commercial fisheries were licensed by the state of Michigan to operate in Lake Erie waters. A total of 1,041,167 pounds were collected in the Lake Erie commercial fishery in 2013. Common carp, white bass, buffalo, quillback carpsucker, and channel catfish comprised the majority (82%) of the catch (Wills and Thomas, 2014). On the Detroit River, commercial fisheries for lake whitefish, lake herring and lake sturgeon existed in the late 1800s and early 1900s; however, these fisheries ceased operation by 1920 (Christie, 1974). Small commercial fisheries for walleye, yellow perch, and common carp continued until World War II. No commercial fishery has operated on the Detroit River since 1970.
The Detroit River provides habitat, serves as a migratory route for many fish species, and is considered to be within the same ecological system as Lake St. Clair and Lake Erie (U.S. Fish & Wildlife Service
[USFWS], 1970). In the past, relatively little was known about the recreational fishery on the Detroit River.
Cooper (1952) conducted a creel survey from 1945 to 1952 and found that the catch was dominated by yellow perch, white bass, walleye, and northern pike. Yellow perch, bass, and walleye dominated the sport catch in 1972 (Jameson, 1973).
The Michigan Department of Natural Resources (MDNR) conducts annual creel surveys of the Lake Erie, Detroit River, and Lake St. Clair sport fishery (charter and non-charter). In 2013, an estimated 339,390 fishes were harvested from the Michigan waters of Lake Erie (Wills and Thomas, 2014). Walleye and yellow perch dominated both the recreational harvest (83%) and the charter harvest (97%). Other abundant species identified in the creel survey were channel catfish, white bass, and smallmouth bass.
For Michigan-based charter boats on Lake Erie, fish harvests were estimated at 22,723 fishes. For non-charter recreational anglers, an estimated 316,667 fishes were harvested from Michigan waters of Lake Erie (Wills and Thomas, 2014).
Historically, the water surrounding the Fermi 2 Power Plant has exhibited productive recreational fisheries, with Cole (1976) reporting that fishing effort was five to six times greater in the Monroe Power Plant discharge than in Lake Erie. It is common for anglers to target power plant discharges for recreational fishing, particularly in the colder months (Bimber and Nigro, 1982; Darkes; Lichtkoppler and Kelch, 1986; Thomas and Haas, 2008). The most abundant species in the catch were white crappie and white bass, followed by channel catfish, bullheads, largemouth bass, smallmouth bass, and northern pike (Cole, 1976). In 1986, a 1-year angling study in the Monroe Power Plant discharge canal estimated 41,000 fishes were caught in 10,000 angler days (Resource Econometrics, 1986). The most common species caught were channel catfish, white bass, crappie, bluegill, freshwater drum, and walleye (Resource Econometrics, 1986).
Section 4.2.1 identifies the two impingement and entrainment studies that have been conducted at the Fermi 2 Power Plant. These provide information characterizing the fish community in the vicinity of the Plant intake.

The reproductive period and characteristics of taxa that are most susceptible to impingement and entrainment, are identified in the more sampling intensive LM&S study (1993), and are summarized in Tables 4.6 through 4.8. This information is important in the source water biological characterization because impingement and entrainment are influenced by life history parameters as well as seasonal variability in the fishes that are present in the source water.

Tetra Tech, Inc.                                                                                             4.4      Data representative of the seasonal and daily activities (e.g., feeding and water column migration) of biological organisms in the vicinity of the cooling water intake structure [(r)(4)(v)]
Fish species present in the vicinity of the intake structure utilize that habitat differently on a seasonal and life stage-specific basis. Some species are present as year-round residents, while others occur on a seasonal basis, or only at a certain life stage. Information on the seasonal and daily activities for species impinged and entrained at high abundances is provided below.
4.4.1    Gizzard Shad Gizzard shad occur throughout Lake Erie and provide an important food resource for many sport fish (Madenjian et al, 1996). Lake Erie is on the northern fringe of their range, therefore gizzard shad are susceptible to mortality due to cold shock. Warm water discharge attracts large numbers to the area, increasing abundance near the facility (Jude, 1983). They often form large schools near the surface, where they feed on zooplankton and phytoplankton, as well as detritus (ODNR, 2012a). Spawning occurs in spring months and continues through the summer, broadcasting their eggs in shallow waters.
During the 1991-1992 study period, gizzard shad accounted for 71.5% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in February 1992. Gizzard shad accounted for 59.4% of larval and juvenile entrainment during post traveling screen collections.
Entrainment of larval and juvenile gizzard shad peaked in June 1992. Gizzard shad larvae and juveniles accounted for 19.0% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.
4.4.2    Rock Bass The rock bass is an important recreational species throughout the Great Lakes region. They occur in shallow bays with rock or gravel substrate and areas of protected cover. Their diet consists of aquatic insects, crayfish, and small fishes. Spawning occurs in late spring. During spawning, males create nests, which they maintain and guard as well as protect fry (MDNR, 2014).
During the 1991-1992 study period, rock bass accounted for 3.4% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in April 1992. Rock bass accounted for
>1.0% of post traveling screen entrainment abundance and was absent from the intake canal entrainment collections.
4.4.3    Emerald Shiner Emerald shiner occur throughout Lake Erie and provide an important food resource for many sport fish (ODNR 2012b). They often form large schools near the surface, where they feed on zooplankton, insect larvae, and small insects. Emerald shiners spawn throughout the spring and summer, broadcasting eggs in open water with no particular substrate preference (ODNR, 2012b).
During the 1991-1992 study period, emerald shiner accounted for 3.1% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in April 1992. Emerald shiner accounted for 5.3% of larval and juvenile entrainment during post traveling screen collections.
Entrainment of larval and juvenile emerald shiner peaked in July 1992. Emerald shiner larvae and juveniles accounted for <0.1% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.
4.4.4    White Perch The white perch is a non-native species in the Great Lakes arriving through the Erie and Welland canals and due to unauthorized stocking (MNDNR, 2015; GLERL, 2009). They are native to the Atlantic coastal region of the United States (MNDNR, 2015). The native populations of white perch are marine and estuarine. Lake Erie stocks are commonly found in shallow and nearshore areas of Lake Erie (MNSG, 2004). White perch primarily prey on fish eggs and small fishes (MNSG, 2004). White perch spawn from 316b Application Requirements                                                                          April 2015

Tetra Tech, Inc.                                                                                         mid-May to late June in the Great Lakes. Spawns occur in shallow water in calm ponds, lakes, or rivers (Auer, 1982).
During the 1991-1992 study period, white perch accounted for 6.8% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in February 1992. White perch were not collected during post traveling screen collections. White perch larvae and juveniles accounted for 6.1% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.
4.4.5    Freshwater Drum The freshwater drum is an important commercial and recreational species of the Great Lakes. Preferred habitat for freshwater drum are pools or channels of rivers (GLERL, 2009). As hatchlings and juveniles, their diet consists of copepods, water fleas, aquatic insects, and small crustaceans. Their diet transitions over to snails and clams as adults, using pharyngeal teeth to crush shells (GLERL, 2009). Spawning occurs from April through early June throughout most of the Great Lakes, however longer spawning seasons have been observed in Lake Erie (Auer, 1982). They spawn in tributaries and streams. They create a drumming noise during spawning events (IDFW). Eggs are released in open water, where the eggs float for one to two days before hatching.
During the 1991-1992 study period, freshwater drum accounted for 3.1% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in October 1991. Freshwater drum were not collected during post traveling screen collections. Freshwater drum larvae and juveniles accounted for <0.2% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.
4.4.6    Spottail Shiner The spottail shiner is a highly abundant forage species in the Great Lakes region. They can be found at depths of 3 to 60 ft over substrate of sand or gravel (ODNR, 2012c). Their diet consists of a variety of aquatic invertebrates. Spottail shiners spawn in May and June, possibly multiple times.
During the 1991-1992 study period, spottail shiner accounted for 1.4% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in November 1991. Spottail shiner accounted for 18.0% of larval and juvenile entrainment during post traveling screen collections.
Entrainment of larval and juvenile spottail shiner peaked in June 1992. Spottail shiner larvae and juveniles accounted for <0.1% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.
4.4.7    Yellow Perch Yellow perch occur throughout the Great Lakes region and are one of the regions most important recreational species (Werner, 2004). Adults and juveniles typically occur in shallow waters in depths of
<20 m near shore (Dettmers et al., 2005), often associated with submerged aquatic vegetation or other rooted vegetation substrate, where they feed on aquatic macroinvertebrates and small fishes (ODNR, 2012d). They often move in loosely organized groups (shoals) and are primarily active during daylight hours (Werner, 2004). Yellow perch remain active throughout the winter. Spawning can occur between late February through early July (Hokanson, 1977). Yellow perch eggs occur in ribbons and are demersal and adhere to aquatic vegetation and rocky bottoms.
During the 1991-1992 study period, yellow perch accounted for 1.8% of total impingement abundance at the Fermi 2 Power Plant. Peak impingement abundance occurred in April 1992. Yellow perch accounted for 6.6% of larval and juvenile entrainment during post traveling screen collections. Entrainment of larval and juvenile yellow perch peaked in June 1992. Yellow perch larvae and juveniles accounted for 0.6% of total entrainment during intake canal collections. Eggs were not collected during intake canal collections.

Tetra Tech, Inc.                                                                                          4.7       Supporting Documentation for Field Studies [(r)(4)(viii)]
The results summarized in the preceding sections represent most intensive IM&E field study conducted in (1991-1992) (LM&S,1993). The specific methods used to document impingement and entrainment at the Fermi 2 Power Plant are summarized here.
4.7.1     Entrainment Sampling Protocol Entrainment sampling was conducted post traveling screen and in the intake canal of Fermi 2 Power Plant GWS screenhouse (LM&S, 1993). For post traveling screen collections, two 3.2-mm mesh plankton nets with 1.0-m diameter mouth were positioned behind each of the two traveling screens. During each sample, the nets were lowered to the bottom of the pump bay and left on the bottom for a minimum of five minutes. One hour replicate samples were collected during each scheduled sampling date. Replicates at each sampling location were combined.
Replicates at each location were combined and sorted by species after collection. No more than 30 individuals per species were measured for total length (mm). Fish collected in smaller samples were identified and measured at time of collection if time allowed. The contents of all other samples were placed in double-labeled jars with preservative to be analyzed in a laboratory.
Entrainment sampling in the intake canal was conducted on a seasonal stratified schedule. Sampling took place at the two traveling screens immediately in front of the opening between the intake canal and the traveling screen bay. Two 6-in diameter trash pumps collected samples at a rate of 3.2 +/- 0.2 m3/min into a submerged 363-&#xb5;m conical nets; one pair of nets at each location. A 30-min sample was collected every hour for 24-hours at each location. Collections were made simultaneously at four depths using a common intake manifold with openings equivalent to each depth; bottom, two intermediate depths, and thesurface . To prevent damage to collected organisms due to debris loading, sample water was directed into a different net at the end of each 30-min sample.
After each 30-min collection, nets at each location were washed down into the cod end. Contents from the cod end were stored in preservative and Rose Bengal. Samples were consolidated into four 6-hr samples per location. In the laboratory, ichthyoplankton were sorted by life stage, identified to the lowest possible taxon, and enumerated. For each 6-hr sample, at least 20 larvae per life stage (yolk-sac and post yolk-sac) were measured to the nearest 0.1 mm, when possible. If a life stage was absent or of there were fewer than 20 specimens of a life stage, the remaining portion of the quota (40) was apportioned to the other life stage. No more than 40 larvae per taxon were measured. Non-fertilized and dead fish eggs, as well as headless larvae, were not analyzed.
4.7.2     Impingement Impingement sampling was conducted once per week over a 24-hour period at the GSW screenhouse.
Impinged fishes were washed from the traveling screens into a sluiceway, and collected in a steel frame collection basket with 6.4-mm square aluminum mesh. During intermittent screen rotation operations, two complete screen rotations and wash downs were conducted prior to the collection basket being placed into the sluiceway and prior to being removed from the sluiceway. During continuous screen operation, the collection basket was placed at the beginning of the 24-hr collection. The collection basket was checked periodically to prevent debris loading.
At the end of this period all fishes were removed from the basket and brought to the on-site laboratory facility in water for immediate analysis. Fishes were identified to the lowest practicable taxonomic level, sorted (typically by species), and enumerated. Game fish species were measured (mm) and weighed (g) individually. Non-game fish were measured individually and a batch weight (g) obtained for each species.
4.7.3     Data Analysis Entrainment data were converted to a 24-hour collection period by adjusting for sample volumes (LM&S, 1993). To calculate the density of entrained eggs and larval fishes, the corresponding sampling volume was divided into the number entrained during each sampling period. Average weekly entrainment 316b Application Requirements                                                                       April 2015

Tetra Tech, Inc.                                                                                          estimates were multiplied by monthly flow volumes to obtain entrainment estimates for each month and for the full year of sampling.
Impingement data were presented as 1) actual biomass and abundances collected, and 2) biomass and abundances adjusted for screen operation over a 24-hr period. Values were converted to a weekly collection period by adjusting for sampling time, the number of screens turned and/or subsampling (if required). To calculate the base density of impinged fishes, the number impinged during each weekly interval was divided by the total sampling time in hours.
4.7.4     Water Quality and Meteorological Parameters Water quality was assessed at the intake. Intake water temperature (&deg;C) and water transparency (cm) were determined at mid-depth. Water transparency was determined using a secchi disk. The DTE Fermi water level gauge (ID 9063090) lake level gage in the intake forebay was used to measure lake level (ft).
Measurements and weekly calibrations were carried out as described in the manufacturers instruction manual.
4.8       Identification of Protective Measures and Stabilization Activities [122(r)(4)(x)]
Several protective measures are currently in-place,that may minimize impingement mortality and entrainment at the Fermi 2 Power Plant. Each of the intake forebays is submerged. This creates a wall configuration that may prevent the entrainment of some buoyant species of eggs and larvae, although this has not been specifically tested or demonstrated at the Plant. Additionally a Closed-cycle recirculation cooling system is in use for cooling purposes. Section 5 provides full details on this system.
4.9       List of Fragile Species at Facility [(r)(4)(xi)]
Impingement mortality reduction measures are intended to minimize the impacts to non-fragile species, which typically exhibit impingement survival rates of greater than 30%. The fragile species (with survival rates less than 30%) are excluded from this calculation so that the facility can apply impingement survival measures towards those species that are most likely to survive impingement. 40 CFR 125.92(m) list the following species as fragile: alewife, American shad, Atlantic herring, Atlantic long-finned squid, Atlantic menhaden, bay anchovy, blueback herring, bluefish, butterfish, gizzard shad, grey snapper, hickory shad, menhaden, rainbow smelt, round herring, silver anchovy.
Of these species, gizzard shad occur at the Fermi 2 Power Plant in the largest proportion of impingement.
Therefore, as a fragile species, gizzard shad are excluded from the impingement mortality standards.
Michigan is on the northern edge of the gizzard shads distribution. Gizzard shad are very sensitive to water temperature changes, particularly rapid decreases, and each year as the water temperature drops below approximately 5&deg;C, their swimming ability becomes impaired and die-offs routinely occur. These stressed (impaired and moribund) and dead gizzard shad are susceptible to impingement in a power plants CWIS, similar to items such as aquatic plants, leaves, and discarded trash and other debris. By excluding gizzard shad from the impingement mortality calculation, the remaining non-fragile species would presumably exhibit higher survival rates, resulting in a greater impingement survival rate for the facility.
In addition, the list of fragile species for the Fermi 2 Power Plant could include freshwater drum, and white perch (and possibly other, untested species) if BTA is applied and survival rates remain under 30% for these species. An impingement survival study conducted at the Monroe Power Plant, using similar technology and within a similar habitat, notes that 24-hour survival ranged between 13.8% to 62.0% for freshwater drum and between 4.0% to 22.0% for white perch, with screen wash modes ranging from every 8 hours to continuous (Reider, 1984) The continuous screen wash modes exhibited the highest survival for all species tested. The decision to include additional fragile species should be determined through consultation with DTE and the permitting agency (MDEQ).

5.1      Cooling Water System Operation Narrative [122.21(r)(5)(i)]
The Fermi 2 Power Plant utilizes a closed-cycle recirculating cooling water system that consists of the cooling water reservoir (CWR), makeup water system (fed by the makeup pumps in the Lake Erie intake structure), circulating water pumps and pump house, the main condenser and the two cooling towers. A simplified diagram of the Circulating Water System is shown in Figure 3.1.
The CWR base area is nominally 5.5 acres with a mean depth of approximately 17 feet. Roughly 23 million gallons are available for the circulating water pumps. The CWR is sized to support limited operation of the Plant following the loss of makeup water resulting from either sustained strong westerly winds and low Lake Erie water levels occurring simultaneously; or if there is damage to or blockage of the intake structure. In the event this happens and makeup water is still not available, approximately 7.9 million gallons would still remain in the reservoir to supply the GSW following shutdown of the circulating water pumps. (Fermi, 2012a)
The circulating water pumps are mounted and take suction from the circulating water pump pit, located at the low point of the CWR. The water level is monitored in the pit, and if the level is low, a makeup pump, fed by the intake structure, is started. Up to five 180,000 gpm circulating water pumps can be operated during normal plant conditions. Each circulating water pump draws water from the CWR through a stationary screen (0.375-inch square mesh) and provides the pressure for water flow through the closed cycle system. The number of pumps operated are dependent on plant heat load and weather conditions.
The circulating water system supplies the main condenser with cooling water at the condenser inlet water boxes for temperatures ranging from nominal 55&deg;F to 94&deg;F. In the winter, when water temperature is below 55&deg;F, the cooling towers are bypassed. After cooling, circulating water leaves the condenser via two underground 12-foot concrete pipes connected by a 12-foot-diameter equalizing line leading to the cooling towers. Circulating water is then directed to the two hyperbolic natural-draft cooling towers through the cooling tower fill area. Fermi 2 has two 50-percent capacity, hyperbolic, natural draft cross-flow type, concrete cooling towers, each 400 ft high and 454 ft wide at the base. A sloped, reinforced concrete cold water basin is located beneath the shell and flume structures. The cooled water droplets are collected in the cold-water basin, which is sloped to assist in tower drainage to the CWR and silt removal. Cooled water then flows back to the circulating water pump house located at the south end of the CWR. Reservoir water level and total dissolved solids concentration are controlled in the CWR by continuously discharging treated blowdown water to Lake Erie through a 3-foot diameter buried pipe. This decant line conveys the blowdown water to the on-shore discharge structure located at the edge of the vegetation along the lakeshore. Exiting the discharge structure, the blowdown water flows east down a gentle riprap protected slope. Blowdown associated with the CWR, which is also inclusive of other plant effluents, is discharged via NPDES Outfall 001.
A makeup water system replaces the circulating water losses caused by evaporation and blowdown.
Approximately 22,000 to 28,000 gpm of makeup water are required, depending upon the season of the year. Makeup water is fed into the circulating water system from the GSW system discharge or from the circulating water makeup pumps (normal and standby). The average daily evaporative losses associated with the cooling towers (1.9 x 107 gpd) and CWR (115,200 gpd) equates to approximately 13,274 gpm.
Of the evaporative losses from the cooling towers, approximately 900 gpm is associated with drift losses.

GSW withdrawal at the Fermi 2 Power Plant for the various plant systems and the Circulating Water System makeup is dictated by demand and pump capacity. Table 5.1 provides specifics on the pump capacities.

6.1      Impingement Mortality Reduction Studies Completed to Date An impingement and entrainment sampling program was completed by Lawler, Matusky & Skelly Engineers (LM&S) for Detroit Edison Company (DTE) at the Fermi 2 Power Plant general service water pumphouse from October 1991 through September 1992. The estimated annual impingement on the traveling water screens calculated from weekly impingement rates was 13,699 fish, representing 23 species and nine families (LM&S, 1993). As part of the study, velocity measurements were taken in the screen bays during winter, spring, and summer periods. Velocities at various depths generally ranged from 0.1-0.3 fps with a maximum recorded point velocity of 0.5 fps (LM&S, 1993).
A more recent, less intensive impingement and entrainment study was conducted by AECOM, for Black and Vetch, at the Fermi 2 general service water pumphouse from August 2008 through July 2009 (AECOM, 2009). A total of eleven (11) monthly 24-hr samples (6 hr composites) were collected during this period. Samples were not collected in April due to heavy debris loading on the screen. Only 101 fish, representing 15 species and 8 families, were collected from the travelling screens for the entire study period. This would calculate out to an estimated 3,102 fishes for a twelve month period, at the annual operational volume of 17,754 million gallons per year (67,208,472 m3).
6.2      Evaluation of BTA Standards for Impingement Mortality - Compliance Alternatives
[125.94(c)(1-7)]:
Power generation facilities with an intake flow greater than 2 MGD and with more than 25% of the water used for non-contact cooling purposes are subject to the impingement standards. Fermi 2 Power Plant exceeds these flow limits and therefore is subject to the impingement mortality standards. Impingement mortality compliance alternatives defined in [125.94(c)(1-7)] are:
(1) Closed Cycle Recirculating Cooling System (2) 0.5 Feet per Second Through Screen Design Velocity (3) 0.5 Feet per Second Through Screen Actual Velocity (4) Existing Offshore Velocity Cap (5) Modified Traveling Screens (6) Systems of Technologies (7) Impingement Mortality Performance Standard An evaluation of these compliance alternatives for Fermi 2 Power Station is summarized in the following sections.
6.2.1    Option 1: Closed Cycle Recirculating Cooling System The Fermi 2 Power Plant has a closed-cycle recirculating cooling system. Therefore, the facility complies with impingement mortality standards under this option as defined in [125.94(c)(1-7)].
6.2.2    Option 2: 0.5 Feet per Second Through Screen Design Velocity The Fermi 2 Power Plant has a closed-cycle recirculating cooling system. Therefore, the facility is in compliance with Option 1 of the impingement mortality standards as defined in [125.94(c)(1-7)] and the 0.5 fps through screen design velocity option is not applicable for this facility.
6.2.3    Option 3: 0.5 Feet per Second Through-Screen Actual Velocity The Fermi 2 Power Plant has a closed-cycle recirculating cooling system. Therefore, the facility is in compliance with Option 1 of the impingement mortality standards as defined in [125.94(c)(1-7)] and the 0.5 fps through screen actual velocity option is not appropriate for this facility.
316b Application Requirements                                                                    April 2015

Tetra Tech, Inc.                                                                                               6.2.4    Option 4: Existing Offshore Velocity Cap The Fermi 2 Power Plant does not currently have an offshore velocity cap. Since the facility has a closed-cycle recirculating cooling system in compliance with Option 1 of the impingement mortality standards as defined in [125.94(c)(1-7), installation of an offshore velocity cap is not applicable to this facility.
6.2.5    Option 5: Modified Traveling Water Screens The Fermi 2 Power Plant has a closed-cycle recirculating cooling system. Therefore, the facility is in compliance with Option 1 of the impingement mortality standards as defined in [125.94(c)(1-7)] and the modified traveling water screen option, including either Ristroph screens, Hydrolox belt screens, or Geiger disc screens, is not needed for this facility.
6.2.6    Option 6: Systems of Technologies The Fermi 2 Power Plant has a closed-cycle recirculating cooling system. Therefore, the facility is in compliance with Option 1 of the impingement mortality standards as defined in [125.94(c)(1-7)] and the system of technologies option, including behavioral barriers, fish diversion systems, and/or reduced flow operations, is not needed for this facility.
6.2.7    Option 7: Impingement Mortality Performance Standard The impingement mortality performance standard is a compliance option only if a facility can document and verify, via monthly monitoring, that their annual average impingement mortality is less than 24%.
Optimization studies and routine monitoring would be necessary to verify that continuous operation of the existing screens would meet the standard. These results are highly uncertain and may require additional implementation of additional compliance alternatives. Since the facility has a closed-cycle recirculating cooling system, this compliance option is not needed for Fermi 2 Power Plant.

: 7) 24% Impingement mortality standard                              Yes                  Not Needed The Fermi 2 Power Plant currently features a closed cycle recirculating cooling system. Further modifications to the CWIS are not necessary at the facility. Performance optimization studies, described in Section 6.3.2 for modified traveling screens and Section 6.3.3 for systems of technologies, are not necessary at the Fermi 2 Power Plant.
6.3.2    Modified Traveling Screens Performance Optimization Study [122.21(r)(6)(i)]
Section 122.21(r)(6)(i) requires a performance option study for facilities that choose modified traveling water screens to meet the impingement compliance standard. The study must include:
: 1. Two years of data collection measuring the reduction in impingement mortality and optimization to minimize mortality
: 2. Complete description of modified screens and associated equipment
: 3. A description of any biological data collection and approach must include:

The Director may establish more frequent data collection; (b) Biological data collection representative of the impingement and the impingement mortality at the intakes subject to this provision; (c) A taxonomic identification to the lowest taxon possible of all organisms collected; (d) The method in which naturally moribund organisms are identified and taken into account; (e) The method in which mortality due to holding times is taken into account; (f) If the facility entraps fish or shellfish, a count of entrapment, as defined at 40 CFR 125.92(j), as impingement mortality; and (g) The percent impingement mortality reflecting optimized operation of the modified traveling screen and all supporting calculations.
Because the facility features a closed-cycle recirculating cooling system, modified traveling water screens are not recommended and a performance optimization study is not required for the Fermi 2 Power Plant.
6.3.3    Systems Of Technologies              Performance       Optimization  Study     -  Biological     Data
[122.21(r)(6)(ii)]
Section 122.21(r)(6)(i) requires a performance option study for facilities that choose a system of technologies to meet the impingement compliance standard. The systems can include flow reductions, seasonal operation, unit closure credit for intake location, and behavioral deterrent systems. The study must include:
: 1. Documentation on how each system contributes to the impingement mortality reduction.
: 2. Two years of biological data collection measuring the reduction in impingement mortality and optimization to minimize mortality.
: 3. If system demonstration relies on credit for decreases of impingement in the system, Section 122.21(r)(6)(ii)(A) requires an estimate of those reductions to be used as credit towards reducing impingement mortality, and any relevant supporting documentation, including previously collected biological data, performance reviews, and previously conducted performance studies not already submitted to the Director. The submission of studies more than 10 years old must include an explanation of why the data are still relevant and representative of conditions at the facility and explain how the data should be interpreted using the definitions of impingement and entrapment at 40 CFR 125.92(n) and (j), respectively. The estimated reductions in rate of impingement must be based on a comparison of the system to a once-through cooling system with a traveling screen whose point of withdrawal from the surface water source is located at the shoreline of the source waterbody. For impoundments that are waters of the United States in whole or in part, the facility's rate of impingement must be measured at a location within the cooling water intake system that the Director deems appropriate. In addition, two years of biological data collection must be submitted demonstrating the rate of impingement resulting from the system. For this demonstration, data must be collected no less frequently than monthly. The director may establish more frequent data collection.

If system demonstration relies on credit for decreases of impingement already achieved, Section 122.21(r)(6)(ii)(B)(1-6) requires two years of biological data collection demonstrating the level of impingement mortality the system is capable of achieving. Any relevant supporting documentation, including previously collected biological data, performance reviews, and previously conducted performance studies not already submitted must be provided to the Director. A description of any sampling or data collection approach used in measuring impingement mortality must be provided to the Director. In addition, for this demonstration the applicant must:
(a) Collect data no less frequently than monthly. The Director may establish more frequent data collection; (b) Conduct biological data collection that is representative of the impingement and the impingement mortality at an intake subject to this provision. In addition, the applicant must describe how the location of the cooling water intake structure in the water body and the water column are accounted for in the points of data collection; (c) Include a taxonomic identification to the lowest taxon possible of all organisms to be collected; (d) Describe the method in which naturally moribund organisms are identified and taken into account; (e) Describe the method in which mortality due to holding times is taken into account; and (f) If the facility entraps fish or shellfish, a count of the entrapment, as defined at 40 CFR 125.92(j), as impingement mortality.
: 5. If system demonstration relies on reductions in flow, Section 122.21(r)(6)(ii)(C) requires two years of intake flows, measured daily, as part of the demonstration, and describe the extent to which flow reductions are seasonal or intermittent. The demonstration must document how the flow reduction results in reduced impingement and describe how the reduction in impingement has reduced impingement mortality.
: 6. Section 122.21(r)(6)(ii)(D) requires documentation of the percent impingement mortality reflecting optimized operation of the total system of technologies, operational measures, and best management practices and all supporting calculations. The total system performance is the combination of the impingement mortality performance reflected in paragraphs (r)(6)(ii)(A), (B),
and (C) of this section.
Because the facility features a closed-cycle recirculating cooling system, a system of technologies is not recommended and a performance optimization study is not required for the Fermi 2 Power Plant.

7.1       Previously Conducted Studies On-Site No facility specific entrainment survival studies have been performed at the Fermi 2 Power Plant. A study was performed at the Monroe Power Plant, located on Lake Erie just south of the Fermi 2 Power Plant.
The Monroe Power Plant study is presented in Section 7.2.
7.2       Previously Conducted Studies From Other Facilities and Relevance 7.2.1 Monroe Power Plant A fish entrainment survival study was conducted from 4 May to 8 July 1982 at the Monroe Power Plant (Ecological Analyst, Inc, 1983). Sampling occurred 4 days a week during the first 8 weeks, and 2 days per week during the last 2 weeks of the study. A rear-draw larva table (Barrel Sampler) was used. Initial and extended 48-hr survival test were performed. Cooling water intake flow was >2000 MGD during sampling.
Entrainment survival estimates were high for minnow and white bass post larvae and freshwater drum pro and post larvae, ranging from 75 to 100%, but lower for clupeids (1-38%) and yellow perch (3%). Table 7.1 summarizes the results.

                *Total Entrainment Survival based on comparison of extended survival between intake and discharge, i.e.: (a) initial survival; (b) 3-hr extended survival; (c) 24-hr extended survival.
Daily discharge temperatures were primarily between 29 and 31&deg;C. Survival of yellow perch and clupeids decreased with increasing discharge temperature. Younger clupeids (prolarvae) had lower survival. Total residual chlorine at > 0.1 mg/L reduced survival of clupeid and yellow perch larvae. The number of circulating-water pumps operating did not affect survival.
7.2.2 Relevance to the Fermi 2 Power Plant The preceding entrainment survival study was conducted at a different facility located on Lake Erie within 7 miles of the Fermi 2 Power Plant. Both power plants utilize the same source water and share similar habitat features, including similar species compositions and water temperature increases through the condenser. Collectively, the percent abundances of larval fish stages tested for entrainment survival (Clupeidae, Cyprinidae, white bass, yellow perch, and freshwater drum) at the Monroe Power Plant (71.2%) are present in similar abundances at the Fermi 2 Power Plant (51.1%; LM&S, 1993). Because of these similar physical and biological characteristics, the entrainment survival data from Monroe may also be applicable to the Fermi 2 Power Plant if the latter plant had once-through cooling. However, for facilities with closed-cycle cooling there is little, if any, survival of entrained organisms.

8.1      Description of the Operation of the Power Production or Steam Generation
[122.21(r)(8)(i)]
The Fermi 2 Power Plant uses a General Electric Company (GE) single-cycle, forced-circulation boiling water reactor (BWR) of the BWR 4 Class, with pressure-suppression Mark I containment, a thermal power limit of 3,486 megawatts thermal (MWt) and net electrical capacity of 1,170 MWe. The reactor pressure vessel contains the core and supporting structures; steam separators and dryers; jet pumps; control rod guide tubes; distribution lines for the feedwater; core sprays; and standby liquid control, in-core instrumentation, and other components. The main connections to the reactor pressure vessel include the steam lines, the coolant recirculation lines and feedwater.
The reactor core is cooled by demineralized water that enters the lower portion of the core and boils as it flows upward around the fuel rods. The steam leaving the core is dried by steam separators and dryers located in the upper portion of the reactor pressure vessel. The steam is then directed through four steam lines to the turbine. Each steam line is provided with three isolation valves in series: one inside the primary containment, and two outside the primary containment.
The reactor recirculation system consists of two recirculation pump loops external to the reactor vessel but inside the primary containment. These loops provide the piping path for the driving flow of water to the reactor vessel jet pumps that provide continuous internal circulation of the core coolant flow.
The reactor core includes an array of fuel rods that creates heat from a controlled nuclear reaction that occurs when control rods are withdrawn. Fuel for the reactor core consists of enriched uranium dioxide pellets sealed in Zircaloy-2 tubes. Fuel enrichment and average peak rod burnup conditions are no more than 5 percent uranium-235 and 60,000 megawatt-days per metric ton of uranium (MWd/MTU),
respectively.
The Plant operates year round, 7 days a week, 24 hours a day, with the exception of refueling outages.
The next two major outages are Refueling Outage RF-17 (begins September 28, 2015 and lasts about a month) and Refueling Outage RF-18 (scheduled for March 20 through April 19, 2017). Refueling outages will then continue on an approximate 18-month frequency.
The annual capacity factor for the Fermi 2 Power Plant based on a 3-year average of 2010--2012 is 76.7 percent (DTE, 2014). The capacity factor for the 2014 operating year was 79% and is targeted to remain near or above this value throughout the plant's operating life.
8.2      NRC Relicensing Status at Nuclear Facilities [122.21(r)(8)(ii)]
The Fermi 2 Power Plant is currently in the process of relicensing with the Nuclear Regulatory Commission. Table 8.1 provides the current relicensing status, with milestone dates.

Two 12-month entrainment characterization studies were conducted at the Fermi 2 Power Plant in 1991-1992 and in 2008-2009. The results of those studies are summarized in Section 4, and the sampling methods and data analyses are described in the associated entrainment study reports (LM&S 1993; AECOM, 2009b). Collectively, these reports provide the following entrainment data to satisfy I(9)(i):
Identify and document the data collection period and frequency; o    October 1991 to September 1992 Study: During October to February, samples were collected monthly for a 24-hr duration (6 hr composites). During March to September, samples were collected weekly for a 24-hr duration (6 hr composites) o    July 2008 to July 2009 Study: During the July to November 2008 and March and July 2009 sampling events, samples were collected monthly for a 24-hr duration (6 hr composites). During April to June 2009, samples were collected twice monthly for a 24-hr duration (6 hr composites). No sampling occurred during the December to February timeperiod as a result of icing.
Identify and document organisms collected to the lowest taxon possible of all life stages of fish and shellfish that are in the vicinity of the cooling water intake structure(s) and are susceptible to entrainment, including any organisms identified by the Director, and any species protected under Federal, State, or Tribal law, including threatened or endangered species with a habitat range that includes waters in the vicinity of the cooling water intake structure.
o    Table 9.1 lists the entrained taxa collected during each entrainment study, with indications of any federal, state, or tribal law protections, where applicable.
o    The final reports associated with each of these studies provide detailed taxa-specific breakouts of entrainment densities and flow-based projections (also summarized in Table, 4.2, 4.3 and 4.5 of this document).

9.2.1    Fermi 2 Power Plant 1991-1992 Study An entrainment and impingement study was conducted at the Fermi 2 Power Plant in 1991-1992 (LM&S, 1993).The following sections summarize the data collection methods and results for entrainment only.
More detailed descriptions of the sampling, identification and abundance calculation methodologies, along with a complete analysis of the collected data can be found in the source document.
9.2.2    Methods Entrainment sampling was conducted just upstream of the traveling screens in the intake canal of the Fermi 2 Power Plant using the protocol described by Lawler, Matusky & Skelly Engineers (1993),
Entrainment sampling methods are described in more detail in Section 4.7.
9.2.3    Entrainment Characterization The results from the previous entrainment studies at the Fermi 2 Power Plant are summarized in Section 4 of this document. Entrainment at the Fermi 2 Power Plant is dominated by gizzard shad, Cyprinidae, and Morone sp (Section 4.2.1). Most of the entrainment occurred May through August, peaking during July. Diel sampling showed greater entrainment abundances during daytime sampling events; however, there were no significant differences between the four 6-hr sample periods. Additional details and percent compositions are included in Section 4.2.1 and Table 4.3. Sections 4.3 and 4.4 (including Table 4.10 and Table 4-11) provide information on seasonal and daily activities for the most frequently entrained fishes at the Plant, including pertinent characteristics of those species life history, seasonal abundance, and habitat use.
9.3      Analysis and Supporting Documentation [122.21(r)(9)(iii)]

ltn,~e Flow  (QJ fiigure 1: Hydra1!1.li Zone of In.fl'nence Defurition Sketch In this scenario, the HZI is defined as the location where the average ambient wind-induced velocity (Vma) in the source waterbody is equal to the velocity induced by the intake. Beyond this point, the wind induced currents will dominate the flow patterns. The radial distance from the intake structure at the shoreline to the dividing line that defines the boundary of the Hydraulic Zone of Influence in an open body of water, RHZI (see definition sketch above), can be estimated from continuity using the following formulas:
(1)  = (180)
Rearranging terms in equation (1) gives:
(2) R HZI = (Q i  (180))(  dr  Vma )
Wind induced surface drift velocities are typically 2 to 3 percent of the average wind speed (Wiegel, 1964). Therefore, under conditions of a gentle breeze (average wind speed of 8 - 12 miles per hour) the surface drift velocity would be 0.2 ft/s to 0.5 ft/s. The average ambient velocity (i.e., the velocity averaged over the depth of the water column) will be less than the surface drift velocity. The relationship will depend on many factors including the speed and duration of the wind, and the depth of the water. In coastal waters, the average velocity is typically 40 to 60 percent of the surface drift current. Therefore, 0.1 ft/s to 0.3 ft/s represent reasonable estimates of Vma for wind induce currents. These values are also typical of net tidal induced currents (peak flood and ebb tide currents are often much greater). In other words, at a location where the intake induced velocity is less than 0.1 ft/s to 0.3 ft/s, the ambient wind-induced currents and/or tidal drift currents likely will dominate the flow patterns and the hydraulic influence of the intake will no longer be significant.

channels by a w'1pfof}p~cr~;tepiei each of the channels is 4.7 m (15.5 ft) wide. The depth of the intake canal gradually increases, reaching a bottom elevation of 168.9 m (554.0 ft),
which results in a maximum water depth of 5.6 m (18.5 ft) at mean lake level. Water enters the pumphouse through two submerged intake openings, each the width of the canal with a vertical opening of 2. 7 m (9.0 ft) measured from the bottom of the intake. Angled steel bar trash racks with clear open space between bars of 7.6 cm (3.0-in.) are located upstream of each submerged opening.
Water enters the pumphouse into       two separate screen bays, each measuring 3.6 m (11.75 ft) in width. A conventional vertical traveling screen equipped with 9.5-mm (0.38-in.) square mesh is located at the mid-point end of each bay. Water passes through the traveling screens and is eventually combined approximately 4.0 m (13 ft) downstream of the traveling screens and 6.3 m (21 ft) upstream of the GSW pumps.
In general, during cold-water periods, three of the five GSW pumps operate. Four service water pumps operate during the warmer water periods normally encountered during the spring and the fall. Five pumps operate during the period of peak water temperatures in the summer. Make-up pumps operate on an intermittent schedule to maintain the circulating water reservoir level.

Traveling screen impingement surveys were conducted on a once-per-week schedule, with each survey covering a 24-hr period. Fish impinged on the two intake traveling screens were collected from the common screenwash sluiceway at a point downstream of the screens (Figure 4-1) in a steel frame basket equipped with 6.4-mm (0.25-in.) square aluminum mesh (Figure 4-2) designed to intercept the entire screenwash flow. Under intermittent screen operation, the screens were washed through two .complete revolutions prior to the collection basket being placed in the sluiceway. Under continuous screen operation the collection basket was placed in the sluiceway at the start of the 24-hr sample period. Intermittently operated screens were washed through two cqmplete cycles at the end of the 24-hr sample period, i.e., prior to removing the coilection basket from the screenwash sluiceway.                                    The impingement collection basket was checked periodically throughout the 24-hr sample period to prevent possible sample loss due to debris loading or large numbers of fish.

Weekly 24-hr impingement collections were generally conducted starting on Tuesday morning; however, if entrainment sampling was scheduled for that day the initiation of impingement sampling was shifted to either Monday morning or Wednesday afternoon. Over the study period, one impingement sample was collected during each week, for a total of 53 samples.
At the end of the 24-hr sample period, the collection basket was removed from the screenwash sluiceway and the entire contents transferred to a plastic container for transport to the on-site laboratory facility.
Water temperature, pH, and transparency (measured using a 22.9-cm [9.0-in.] Secchi disk) were recorded from the intake canal at a location on the west side of the canal upstream of entrainment collection location El. (Figure 4-1 ). Water quality samples were collected at mid-depth at the beginning and end of each 24-hr *sample period. Wind speed and direction, barometric pressure, air temperature, cloud cover, lake conditions, and lake level were recorded from a* mini weather station
* located on the field laboratory trailer and by
) observation;    Lake level data were taken from the DECo lake level gage in . the intake forebay. Weather parameters were recorded at the beginning and end of each sample period.
4.1.1.2 *Sample 'Analysis Procedures. Impinged fish were returned to the field laboratory in water for imme.diate analysis. Fish were separated into game and nongame species. Each game fish was measured (total length, mm) and weighed (g) individually. Nongame fish species were measured (total length, mm) individually and the batch weight of each species was determined'. Representative fish specimens were preserved in buffered formalin and sent to the Lawler, Matusky & Skelly Engineers (LMS) Nyack, New York laboratory for quality control (QC) analysis. Following the on site analysis the samples that were not retained for QC analysis were returned to the traveling screen sluiceway for disposal.
The continuous sampling plan (CSP-1) (Hansen 1953) was used to ensure that no more than a 10% error occurred in the identification or enumeration of specimens in the impingement samples. The program phases are described below:
: 1. A defect is defined as an employee misidentifying or miscounting > 10% of the total species in a sample.
4-2 Lawler, 1'fatusky & Skelly Engineers

                                                                                                        )
: 2. All samples analyzed are listed in numerical order by inventory number and assigned consecutive numbers starting with one. QC is conducted by a qualified fisheries biologist other than the original analyzer(s).
: 3. The CSP-1 program was divided into two modes for selection of samples for QC analysis:
* Mode 1. The first 14 24-hr samples were subject to 100% QC reinspection.
* Mode 2. If all 14 samples ( < 10% of fish misidentified or miscounted) from Mode 1 pass reinspection, then one out of a lot of 20 samples was randomly selected for reinspection.
Jf any sample failed during Mode 1, then Mode 1 was repeated until a continuous sequence of 14 samples passed.
If any sample failed during Mode 2, then Mode 1 was automatically reinitiated.
4.1.1.3 Analytical Procedures. The number and biomass of fish collected during each weekly sample date ( adjusted for two-screen operation) were used to estimate the number and
                                                                                                      )
biomass of fish impinged on the Fermi 2 intake traveling screens. Monthly and annual impingement estimates were calculated based on time. Each month was divided into four
* weekly intervals:. days 1 through 7, 8 through 14, 15 through 21, and 22 through the last day of the month. To estimate the weekly impingement rate, the number of fish collected in each weekly interval was divided by the total sampling time in hours. The weekly estimates were the product of the rate and the total hours in the interval. Monthly impingement estimates were the sum of the weekly interval estimates. The monthly estimates were summed to result in the annual estimate of impingement abundance or biomass.
Percentage composition for each species was determined as shown below:
Percentage Composition ; (Total number per species/Total annual estimate) x 100
                                                                                                    )

4.1.2 Posttravcling Screen Juvenile Entrainment Program 4.1.2.1   Sample Collection Procedures. Sampling to collect fish from behind the traveling screens was conducted using plankton nets 'Nith a mouth diameter of 1.0 m (3.3 ft), and square mesh size of 3.2 mm (0.13 in.).       Posttraveling screen entrainment samples were collected at two locations (designated S1 and S2), each approximately 5.4 m (18 ft) downstream of each traveling screen (Figure 4-1). Replicate net samples were collected at each location on an hourly schedule during each scheduled entrainment sampling date (Table 4-1 ). The general sample procedure for each sample consisted of lowering the weighted net,
     &#xa5;.rith the net mouth horizontal to the surface of the water, to the bottom of the pump bay.
The net was left on the bottom for a minimum of 5 minutes; after the 5-min stabilization time, the net was pulled vertically to the surface at a steady rate. The replicate catches for each hour at each location were combined. Water column depth was recorded each h6ur.
At the end of each sample, the net contents were sorted, and if the fish collection was sma11, the fish were identified and measured for total length at the time of collection. However, if the sample contained a large number of fish, the net contents were placed in double-labeled jars containing preservative for analysis at a later date.
4.1.2.2 Sample Analysis Procedures. If time allowed, the collected fish were analyzed at the time of collection; if not, they were taken to the field laboratory for analysis. Samples containing large numbers of organisms were preserved and shipped to the Nyack laboratory for analysis. The fish in the combined replicate samples were sorted and counted by species.
Sampling locations S1 and S2 were treated as separate collections. Up to 30 fish per species per location were measured for total length (mm).
4.1.2.3 Analytical Procedures. The actual number of fish collected in each combined replicate posttraveling screen entrainment sample was recorded.          The volume of water in each combined coUection was calculated using the fol1owing formula:

Intake entrainment sampling was conducted on a seasonally stratified schedule using two 15.2-cm (6.0-in.) trash pumps that concentrated water pumped from the intake canal at the submerged openings to the two screen bays (Figure 4-1) into conical nets with 363-&#xb5; mesh. Sample water (3.2 +/- 0.2 m3/min [840 +/- 40 gpm]) was pumped through pipes connected to a common manifold on the intake side of the pump.
Water was pumped from four depths immediately in front of the 2.7-m (9.0-ft) by 4.7-m (15.5-ft) opening between the i.ntake can.al and the traveling screen bay; the manifold openings corresponded in depth to the bottom, two intermediate depths, and the top of each opening.
                                                                                                    )
Equal volumes of water (0.8 +/- 0.04 m3/min [210 +/- 10 gpml) were withdrawn from each depth. A Signet flowmeter was located on the pump inlet to .monitor sample volume during each 30-min subsample collection period.
The discharge line after the pump was separated into two valved pipes, each capable of discharging into one of two nets that were suspended in the water of the screen bay ( one pair of nets in front of each traveling screen). Sample water at each location was directed into one of the two nets for a minimum of 30 min, and then the flow was switched into the other net as necessary to prevent sample loss and organism damage due to debris loading. At the end of the sample time, the nets (one in each screen bay) were raised and washed down from the outside, concentrating the material in the cod end bucket. After the net wash down, the bucket was detached from the net and its contents carefully poured into a container containing preservative and the vital stain Rose Bengal. The procedure was repeated until the entire 24-hr sampling event was completed. Successive 30-min samples were consolidated into four 6-hr composite samples at each sampling location resulting in eight composites per sample date.
4-5 Lawler, Matusky & Skelly Engineers

)
Water temperature and pH were recorded at the mid-point of each 6-hr sample period.
Water quality ;amples were ~ollected upstream of the El collect.ion location in the intake forebay at mid-depth.
4.1.3.2   Laboratory Sample Analysis. All entrainment samples (6-hr composites) were concentrated in jars and preserved with buffered formalin containing the vital s(ain rose bengaI. Samples were labeled with three complete labels; one inside the jar, a second on the outside of the jar, and a third on the lid. If a sample required more than one jar, it was properly labeled.
Preliminary sample analysis, consisting of separating the fish eggs and larvae from the detrital material collected in the sample, was conducted on all entrainment samples at the on site laboratory facility. Secondary analysis, consisting of species identification and enumeration, life stage designation, and length frequency analysis, was conducted on aU ichthyoplankton samples at the Nyack laboratory by trained fisheries biologists. Ichthyoplankton removed
)
* from each entrainment sample were identified to species (or lowest taxonomic level achievable)'and enumerated according to life stage determinations. Up to 40 larvae per taxon per 6-hr sample were measured to the nearest 0.1 mm.             Fish eggs were identified and counted. Non fertilized eggs or dead eggs that may have been included in the original sort counts were not included in identification and enumeration counts. Headless larvae that may have been included in the original sort counts were not included in identification and enumeration counts. Larvae with heads but no tails were either identified and enumerated but not lengthed or called unidentifiable. When possible, at least 20 organisms per life stage (i.e., yolk-sac larvae and post-yolk-sac larvae) were measured. Organisms were chosen at random from each life stage group until the required number (20) were obtained. If a particular life stage was absent or if there were fewer than 20 specimens of a life stage, the remaining portion of the quota (40) was apportioned to the other life stage.
Signet flowmeters used in entrainment sampling provided a total sample volume (m3) for each 6-hr run. Ichthyoplankton abundance presented as a density was determined as follows:
 )
4-6 Lawler, Matusky & Skelly Engineers

                                     =  (No. of larvae or eggs collected in 6-hr) x Sample Density (No./1000m 3)                                                   1000 (Volume filtered in 6-hr [m3])
Weekly, monthly, and annual entrainment estimates were calculated based on water volume.
Each month was divided into four weekly intervals: days 1 through 7, 8 through 14, 15 through 21, and 22 through the last day of the month. The one exception to this temporal allocation occurred with the 22 July sample collection which was allocated to the 15 through 21 July weekly interval. To estimate the weekly entrainment rate, the numbe.r of ichthyoplankton collected in each weekly interval was divided by the sample volume (m3) for that weekly interval. The weekly estimates were the product of the rate and the total plant flow in the interval. Monthly entrainment estimates were the sum of the weekly interval estimates. The monthly estimates were summed to result in the annual estimate of entrainment abundance.
Quality Assurance/Quality Control (QNQC) procedures consisted of the CSP-1 program to
                                                                                                  )
ensure a minimum outgoing quality level of >90.0%. The same CSP-1 program was used for the entrainment program as described for the impingement program, with the exception of the sample lot sizes. For the entrainment program the Mode-1 and Mode-2 lot sizes were 10, with the analysis being done for each individual analyzer for both preliminary and secondary analysis.
Collection and laboratory analysis information was entered on a IBM-compatible PC through view screen programs following the completion of QNQC procedures.
4.2 DAILY PHYSICAL AND CHEMICAL MONITORING PROGRAM Daily water temperature data were recorded by Fermi 2 plant personnel at the Lake Erie intake structure of the Fermi 1 power plant (the Fermi 1 power plant is out of service). The Fermi 1 intake is located approximately 200 ft west of the Fermi 2 intake on the same channel (Figure 3-2). Lake level data were recorded by the National Oceanic and Atmospheric Administration (NOAA) at the Fermi 1 intake. On days when LMS personnel             )

)
were on site water temperature, lake level, and water transparency were recorded at the Fermi 2 intake. Readings were taken at midday.       Water temperature (&deg;C) and water transparency (Secchi disk, cm) were taken at mid-depth in the intake forebay. Lake level (ft) was recorded from the DECo lake level gage in the intake forebay (Appendix A).
Intake velocity surveys were conducted four times during the one-year Fermi 2 cooling water intake program on 9 and 10 December 1991, 19 February 1992, 29 May 1992, and 5 August 1992. Toe 19 February 1992 survey was conducted at the entrance to the intake canal as a make-up for the survey that was initially conducted at this location on 10 December 1991.
The surveys were scheduled to correspond to anticipated low (three-pump), intermediate (four-pump), and high (five-pump) intake flow conditions, respectively.
) During each survey, velocity depth profiles were conducted in front of each of the two traveling screens and at the entrance to the int?ke canal. At the traveling screens, vertical velocity profiles were made at 0.6-m (2-ft) water intervals from surface to bottom at three locations corresponding to each screen's center and 1.0 m (3.3 ft) inboard from each side.
At the entrance to the intake canal, vertical velocity profiles were recorded from surface to bottom at 0.6-m (2-ft) depth intervals, every 1.0 m (3.3 ft) along a 10.1-m (33-ft) transect established 1.0 m (3.3 ft) downstream from the canal entrance.
The first velocity survey was conducted using a Marsh-McBirney Model 511 dual-axis electromagnetic water current meter. The second, third, and fourth surveys used a Marsh-Birney Model 2000 Flo-Mate electromagnetic flowmeter.

CHAPTERS PHYSICAL/CHEMICAL PROGRAM RESULTS 5.1 INTAKE WATER TEMPERATURE DATA Lake Erie water temperature information recorded daily at the Fermi 1 .intake by plant personnel is presented in Table 5-1. The daily value is graphically presented in Figure 5-1.
Over the annual sampling period Lake Erie water temperature exhibited a relatively sharp decline during the fall months, relatively constant low temperatures during the winter months, a relatively gradual increase during the spring months, followed by constant warm temperatures during the summer months. The greatest rate of temperature change occurred during November (10.6&deg;C [19.1&deg;F]) and the lowest rate of temperature change was noted during February (2.7&deg;C [4.9&deg;F]). The coldest water temperature (0.O&deg;C) was recorded on 17
) January and the highest water temperature (24.4&deg;C [76&deg;F]) was recorded on five dates: 22 July, 23 July, 7 August, 22 August, and 23 August.
5.2 lAKE ERIE WATER LEVEL DATUM Lake Erie water level information is recorded hourly at a station at the Fermi 1 intake by the NOAA Lake level data sheets for each month giving the hourly and daily mean lake level values are presented in Appendix A2. It should be noted that the lake level data for October through December 1991 are referenced to 1955 International Great Lakes Datum (IGLD),
while the January through September 1992 information are referenced to 1985 IGLD.
Daily mean lake level data recorded at the Fermi 1 intake station is presented in Table 5-2, and graphically presented in Figure 5-2.

Water temperature (Figure 5-3) exhibited the characteristic pattern of northern temperate waters, with minimum temperatures recorded during the winter months, a gradual*spring increase reaching the annual maximum during mid-         )
summer, followed by a sharp fall decline. The coldest water temperature (0.l&deg;C [32.2&deg; F]) was recorded on 18 December 1991 and the warmest water temperature of 23.7&deg;C (74.7&deg;F) was recorded on 27 August 1992. Water temperature values recorded during the impingement monitoring program corresponded very closely with the Fermi 1 intake water temperature data presented in Section 5.1. Very little variability was noted in pH, which ranged from 7.0 to 8.9 (Figure 5-4). Water transparency showed a high degree of variability over the study period, ranging from a low of 15.0 cm (0.5 ft) to a high of 440.0 cm ( 14.4 ft) (Figure 5-5).
Lake level (Figure 5-6) ranged from 173.9 m (570.6 ft) recorded at the beginning of December 1991 to 175.0 (574.2 ft) recorded on several dates during the second half of the study period. It should be noted that the data recorded at the Fermi 2 intake are referenced to the USGS datum, while the NOAA data are referenced to the IGLD datum; consequently the data differ.
5.4.2 Entrainment Monitoring Program Water temperature and pH were recorded at the mid-point of each 6-hr entrainment sample            )
period during the 30 sample dates conducted between 22 October 1991 and 23 September 5-2 Lawler, Matusky & Skelly Engineers

1992. During the first four months of the entrainment monitoring program, entrainment sampling was initiated at 0900 hrs, which resulted in water quality information being recorded at 1200, 1800, 2400, and 0600 hrs. Entrainment 'sampling was initiated at 0800 hrs from February through September, which resulted in water quality information being recorded at 1100, 1700, 2300, and 0500 hrs.      Water temperature and pH data recorded during each entrainment monitoring date are presented in Table 5-5.
As with the impingement monitoring program, there was very little pH variability over the 12 sampling months. A low value of 6.9 was recorded on 20 November and a high of 8.9 on 23 January. In general, pH was at or near 8.0 during the majority of the sampling dates. Water temperature values were similar to the values reported from the impingement monitoring program.
5.5 INTAKE WATER VELOCITY PROFILES Intake water velocity surveys were conducted three times during the one-year Fermi 2 Power Plant cooling water intake evaluation program. The surveys were scheduled to correspond to anticipated normal low (winter), high (summer), and intermediate (spring, fall) intake flow conditions.
During each survey, velocity depth profiles were conducted in front of each of *the two traveling screens and at the entrance to the intake canal. Velocity measurements conducted at the two traveling screens on 9 December 1991 were taken using a Marsh-McBirney Model 511 dual-axis electromagnetic water current meter; all subsequent velocity surveys were conducted using a Marsh-McBirney Model 2000 Flow-Mate (single axis) portable electromagnetic water flowmeter. The velocity monitoring probe for the 9 December 1991 survey was oriented with the y-axis perpendicular to the face of the intake traveling screens and the x-axis parallel to the screen face. A positive y-axis velocity value denotes a velocity vector directed toward the screen, and a negative velocity value denotes a velocity vector directed away from the screen. For the x-axis the positive and negarive values designate 5-3 Lawler, Matusky & Skelly Engineers

velocity vectors from the west and east, respectively. In general, combined negative and positive velocity values recorded at the same location correspond to turbulent flow patterns.
Traveling screen velocity measurements were recorded approximately 0.6 m (2.0 ft) upstream from the face of each traveling screen. Velocity measurements were recorded at 0.6-m (2.0-ft) intervals from surface to bottom at locations corresponding to each screen's center and 1.0 m (3.3 ft) inboard from each side. At each sampling point, five readings were obtained at 10-sec intervals.
5.5.1 Winter Survey (9 December 1991 and 19 February 1992)
During the 9 December 1991 survey period extending from 1420 .to 1709 hrs, three general service water pumps (GSW 2, 5, 6) were operating and the west make-up pump was started at 1532 hrs. At the beginning of the survey, water depth in the screenwell was 5.0 m (16.4
)  ft); Lake Erie water level dropped 0.5 m (1.8 ft) during the survey, resulting in a water depth of 4.4 m (14.6 ft) at the end of the survey. Results of the survey are presented for screen A (east screen) in Table 5-6 and for screen B (west screen) in Table 5-7. In general, the greatest velocities were recorded from the waters below mid-depth, with higher velocities observed in front of screen A than screen B. Also, for each screen, higher velocities were recorded on the western side of screen A and in the center and eastern sections of screen B.
This places the higher velocities near the centerline of the intake structure.
Velocity profiles were conducted at the intake canal entrance on 10 December 1991.
However, during evaluation of the data some anomalous readings (probably the result of cold air temperatures that adversely affect the meter's electronic circuits) were noted; this finding led to a second winter survey being conducted on 19 February 1992. Survey results are presented in Table 5-8. During the survey period extending from 1153 to 1254 hrs, three GSW pumps (3, 4, 6) were operating and one make-up pump was on until 1215 hrs.
The highest velocities were noted at the 0.6- and 1.2-m (2.0- and 3.9-ft) depths in the western
) half of the intake. Bottom velocities and surface velocities in the eastern half of the intake were generally low.

5.5.2 Spring Survey (29 May 1992)
The second velocity survey was conducted on 29 May 1992.             During the survey period extending from 1012 to 1108 hrs, three GSW pumps (4, 5, 6) and the west make-up pump were operating. At the beginning and end of the survey, water depth in the screenwell was 5.4 m (17.6 ft). Results of the survey are presented for screen A (east screen) in Table 5-9 and for screen B (west screen) in Table 5-10. The highest average velocity for each screen was recorded at the center below mid-depth.
A velocity profile was also conducted along the intake canal entrance on 29 May 1992 (Table 5-11). During the survey period extending from 1200 to 1239 hrs, three GSW pumps (4, 5,
: 6) and the west make-up pump were in operation. Highest velocities were noted at the 0.6-,
1.2-, and 1.8-m (2.0-, 3.9-, and 5.9-ft) depths within 2.7 m (8.9 ft) of each wall in the intake canal. Bottom velocities and mid-canal velocities were generally low.
 )  5.5.3 Summer Survey (5 August 1992)
A third velocity survey was conducted on 5 August 1992. During the survey period extending from 1030 to 1230 hrs, four GSW pumps (2, 3, 5, 6) were operating. At the beginning and end of the survey, water depth in the screenwell was 5.5 m (18.0 ft). Results of the survey are presented for screen A (east screen) in Table 5-12 and for screen B (west screen) in Table 5-13. The highest average velocity for screen A was recorded at the center of the screen at the bottom of the screenwell. In general, the greatest velocities were recorded from the waters below mid-depth. The highest average velocity for screen B was recorded at mid-depth, along the east side of the screen. Velocities in front of screen B were consistently highest below mid-depth, across the entire screen.
Velocity measurements were recorded along the intake canal transect on the same date.
Survey results are presented in Table 5-14. During the survey period extending from 1345 to 1500 hrs, four GSW pumps (2, 3, 5, 6) were operating.           "The Lake Erie water level remained the same throughout the survey. Areas of the highest velocities were consistently

CHAPTER 6 RESULTS OF BIOLOGICAL MONITORING PROGRAMS 6.1 TRAVELING SCREEN IMPINGEMENT 6.1.1 Program Information Fermi 2 traveling screen impingement sampling was conducted weekly during 53 24-hr periods between 1 October 1991 and 30 September 1992 (Table 6-1). Overall, the weekly scheduled impingement collections accounted for 14.5% of the time expended over the 12-month study period. Monthly collection periods accounted for a low of 12.9% of the time during four months (January, May, July, and August) and a high of 16.7% during two months (June and September). The date, start and end times, traveling screen operational condition and
 )    number of GSW pumps operating for each impingement collection are presented in Table 6s2.
1Jie abundance and biomass of impinged fish was determined in two ways: 1) the actual number and weight of fish collected from all operating traveling screens over a 24-hr period, and 2) abundance and biomass corrected to reflect two-screen operation over the 24-hr sampling period, i.e., the number and weight of the fish collected were doubled on 16 dates (no fish were collected during one date in August) to account for the impingement on the nonoperating screen. The dates on which the catch data were corrected for screen operation were concentrated during the fall and winter months, with six dates occurring during the fall months of 1991 and 10 dates occurring during the winter months of 1992. The actual number of impinged fish collected and their respective weights are presented in the following report section; however, for the discussion of impingement on the Fermi 2 Power Plant intake traveling screens, the corrected data base will be used.

The biomass of impinged fish both actual and corrected for traveling screen operation is presented in Table 6-5. The actual biomass of fish collected during the one-year monitoring program was 26.65 kg;, and the biomass corrected for traveling screen operation was 46.70 kg.
Gizzard shad represented the greatest biomass, with 32.69 kg or 70.0% pf the screen-corrected annual total. The second highest biomass was recorded for freshwater drum, with 6.45 kg or 13.8% of the screen-corrected annual total. Goldfish (1927 g, 4.1 % ), rock bass (904 g, 1.9%), white perch (838 g, 1.8%), largemouth bass (800 g, 1.7%), carp (694 g, 1.5%),
and yellow perch (482 g, 1.0%) rank three through eight in total biomass, respectively, and with the top two species, gizzard shad and freshwater drum, account for greater than 95% of the total annual screen operation corrected biomass.

Gizzard shad. The dominant fish species collected was gizzard shad, accounting for 71.0% of the total number of fish impinged and 70.0% of the total biomass of fish impinged. Gizzard shad were identified in impingement collections during the months of October through June and August (Table 6-4). Length-frequency information by month (Table 6-8), coupled with the average fish weight information, indicates that young-of-year and yearlings constituted the greatest percentage of the gizzard shad impinged, with the occasional collection of an adult.
Young-of-year recruitment (1991 year class) was first noted during the late summer period, with peak concentrations observed during November and December. Growth of the 1991 year class was rapid, reaching an average length of approximately 145 mm by late spring 1992.
White perch. White perch was the second most abundant species impinged, accounting for 7.1 % of the total impingement abundance and 1.8% (rank 5) of the total biomass. White perch were collected during December through July, with the greatest concentration noted during the winter months (late December through March). Length-frequency data (Table 6-
 )    9) indicate that the white perch impinged at Fermi 2 were young-of-year/yearlings representing the 1991 year class; these fish had a total length range from 65 mm recorded in January to 115 mm recorded in July.
Rack bass. The third most abundant fish species impinged on the Fermi 2 traveling screens was rock bass, accounting for 3.3% of the total abundance and 1.9% (rank 4) of the total bio~ass. Rock bass were collected during every month except January and August. Based on length-frequency information (Table 6-10), several rock bass age classes were present in the impingement collections, the greatest percentage being yearlings during late winter and early spring and young-of-year during the fall. Older fish were present during the spring and summer period and were the only age group collected during the early fall period.
Freshwater drum. Freshwater drum was the only species to be identified in impingement collections during every month, accounting for 3.2% of the annual total abundance and 13.8%
(rank 2) of the annual total biomass. Adults ranging in length from 230 to 370 mm (Table 6-11) were collected during most of the study months and accounted for half of the total
   ) impingement. Young-of-year recruitment was noted in October represented an increasing 6-4 Lawler, Matusky & Skelly Engineers

percentage of impinged freshwater drum during the fall months. Yearlings dominated the winter impingement collections.
Emerald shiner. Emerald shiner ranked fifth in overall abundance, representing 3.0% of the total 1991-1992 impingement; however, because of the fish's small size it represented only 0.5% of the total biomass. Emerald shiners were collected during two periods: during the fall months young-of-year and yearlings were impinged (Table 6-12), and during the late winter-early spring period the impingement samples consisted primarily of yearlings and adults (probably two-year-olds).
Bluegill. Bluegill impingement was greatest during the fall period, when 26 of the 31 total specimens were collected. Length-frequency information (Table 6-13) indicates that the fall impingement was primarily young-of-year, with single specimens of yearlings and older adults present during the winter and spring months. No bluegill impingement was recorded during the summer months.                                                                                     )
White bass. White bass were only identified in impingement collections from the fall months when the greatest percentage of those impinged were young-of-year, with a few yearlings also noted (Table 6-14).
Yellow perch, spottail shiner, and trout-perch. The next three species in abundance rank order were yellow perch (1.9% total abundance and 1.0% total biomass), spottail shiner (1.4% total abundance and 0.4% total biomass), and trout-perch (1.0% total abundance and 0.2% total biomass). Overall impingement of the three species was very low, limiting comments on temporal distribution and growth parameters. Yellow perch (Table 6-15) were collected during the fall as young-of-year and yearlings, with a second period of abundance during the winter and early spring comprised primarily of yearlings and older fish. Spottail shiners were collected in low abundance every month except during summer when none were collected.
The winter and spring catches were primarily one- and two-year-old specimens (Table 6-16),
with young-of-year occurring during the fall. Trout-perch were collected during three months
- March, April, and November - with little variation noted in total length between months (Table 6-17).

The greatest number of fish were estimated impinged during February and March, with 4066 and 3339 fish, respectively. The lowest estimated impingement, 14 fish, was calculated for September. Gizzard shad was the dominant species impinged, with an estimated annual impingement of 9798 individuals, or 71.5% of the annual total. White perch (926 individuals, 6.8% of annual total), rock bass ( 461 individuals, 3.4% of annual total), freshwater drum ( 430 individuals, 3.1 % of annual total), and emerald shiner ( 424 individuals, 3.1 % of annual total) completed the top five fish species impinged in rank order, respectively.
 )    Estimated impingement biomass for each species and total fish is presented in Table 6-19.
Estimated impingement biomass calculations are presented in Appendix E.                The total estimated biomass of fish impinged on the Penni 2 traveling screens between 1 October 1991 and 30 September 1992 was 329.8 kg (727.1 lb). Gizzard shad dominated the estimated impingement biomass, with 229.5 kg (506.1 lb), or 69.6% of the estimated annual total.
Freshwater drum ranked second in estimated biomass, accounting for 12.9% ( 42.5 kg, 93. 7 lb) of the annual estimated total. Three species. goldfish (ranked third), largemouth bass
( ranked sixth), and carp ( ranked seventh) - were in the top 10 species for biomass and not for abundance, based primarily on the collection of single large specimens.

time eiqiended over the 12-month study period, with monthly collection periods accounting for a low of 0.4% of the time during October and a high of 2.8% during the month of June.
Posttraveling screen entrainment was conducted in a common, unrestricted area of the intake downstream of the two traveling screens, with sample collection sites located one on each side of the intake structure center wall (Figure 4-1).
The Fermi 2 posttraveling screen entrainment sampling program scheduled the collection of 1440 samples (720 from location Sl and 720 from location S2). A total of 1368 samples (661 from Sl and 707 from S2) were actually collected (Table 6-21).

6.2.3 Biological Information on Dominant Species The top seven fish species based on abundance, with each species representing at least 1.0%
of the annual total collection, accounting for 94.3% of the total number of fish collected and 99.3% of the total number of fish identified, were (in rank order): gizzard shad, spottail shiner, yellow perch, emerald shiner, white bass, white sucker, and logperch.        Biological information, including growth patterns based on length-frequency data, is presented in the following sections.
Gizzard shad. The dominant fish species collected was gizzard shad, accounting for 59.4% of the total number of fish collected in the posttraveling screen entrainment samples. Gizzard shad were identified in posttraveling screen entrainment collections during the months of October 1991 and June through September 1992. Length-frequency information by month (Table 6-23), indicates that post-yolk-sac constituted the greatest percentage of gizzard shad entrained during June and juveniles dominated July through August. One gizzard shad was
                                                                                                     )
collected in October, however, it was damaged and no length was recorded. Total length (mm) ranged from an 11-mm post-yolk-sac in June to a 60-mmjuvenile in July.
Spottail shiner. Spottail shiner was the second most abundant species collected, accounting for 18.0% of the total number of fish collected. Spottail shiner was identified in posttraveling screen entrainment collections during June and July. Length-frequency data (Table 6-24) indicate that the spottail shiner collected behind the traveling screens were post-yolk-sac and juveniles, with a total length range from 10 mm recorded in June to 44 mm recorded in July.
Yellow perch. The third most abundant species identified in posttraveling screen entrainment samples was the yellow perch, accounting for 6.6% of the total abundance. Yellow perch were collected during May through August, with the greatest concentration noted during June. Length- frequency data (Table 6-25) indicate that post-yolk-sac and juveniles were collected with a total length range from 10 mm recorded in June to 57 mm recorded in August. One yellow perch collected in May was not measurable.

Emerald shiner. Emerald shiner were collected in eight of the 12 months, accounting for 5.3% of the total abundance; however, it was the only major species not collected during June. Young-of-year/yearlings ranging in length from 31 to 99 mm (Table 6-26) were collected during late winter and early spring (February through May), and accounted for approximately half of the emerald shiners collected. Juveniles ranging in length from 16 to 48 mm were collected during the summer months (July through September).
White bass, white sucker, and logperch. The next three species in abundance rank order were white bass (1.7% total abundance), white sucker (1.7% total abundance), and logperch (1.6%
total abundance). White bass (Table 6-27) were collected during June through September, white sucker (Table 6-28) were collected during June and July and logperch (Table 6-29) were collected during June through August.        Post-y9lk-sac accounted for the greatest percentage of the three species entrained, with the occasional collection of a juvenile.
6.2.4 Monthly and Annual Abundance
                                                                                                    )
The abundance of fish collected downstream of the traveling screens was determined by adding the actual number of fish caught in replicate net collections during each hour of the 24-hr sample period, at the two sampling locations (Sl and S2). Water volume sampled for each collection was recorded at both locations. The total number of fish collected, by date, at each location (Sl and S2), the total number of replicate samples and the total water volume sampled (m3) are presented in Appendix F.
Monthly posttraveling screen entrainment abundance by species and percent composition for the 12 sampling months is presented in Table 6-30. A total of 13,547 fish were collected during Fermi 2 posttraveling screen entrainment sampling. Emerald shiner were collected in eight of the 12 months, while two species, alewife and Pomoxis sp., were represented in collections during only one month. The greatest number of fish were collected during June and July, primarily due to the dominance of the gizzard shad; and the fewest fish were collected from October through February.        The greatest number of species (12) were identified from June, with no fish collected in December and January.                             )

6.3 ICHTHYOPLANKTON ENTRAINMENT 6.3.1 Program Information Fermi 2 ichthyoplankton entrainment sampling was conducted under a seasonally stratified sampling schedule during 30 24-hr periods between 22 October 1991 and 23 September 1992 (Table 6-33). Entrainment sampling accounted for 8.2% of the time over the 12-month study period, with seasonally stratified 24-hr collection periods accounting for a low of 3.2% of the time during three months (October, December, and January) to a high of 16.7% during the month of June. Over the 12-month study period, total plant water withdrawal from Lake Erie, based on pump operation was 57.8 MCM (15,312.42 MG); a total of 4.9 MCM (1,296.81 MG) or 8.5% of the total plant flow was sampled under the entrainment monitoring program.
The percent of plant flow sampled on a monthly basis ranged from 16.5% during June to 3.2% during October, December, and January.

The Fermi 2 entrainment sampling program scheduled the collection of 240 6-hr samples (120 from location El and 120 from location E2). A total of 236 6-hr samples (116 from El and 120 from E2) were actually collected. Entrainment sampling was not conducted at station El on 10-11 March 1992, due to maintenance work on traveling screen B.
6.3.2 Species Representation, Abundance, and Percent Composition Ichthyoplankton entrainment sampling at Fermi 2 during the 12 month period October 1991 through September 1992 resulted in the collection of 28 identifiable taxa (Table 6-34).
Eighteen taxa were identified to species, four taxa were identified to genus and six taxa were identified to family. Eggs and larvae were identified in entrainment collections for five of the 28 identifiable taxa, the remaining 23 taxa were only collected as larvae. The largest number of taxa (six) were members of the perch family (Percidae); six families were represented by a single identifiable species. Seven taxa either designated game fish by the MDNR or known to be subject to sport harvest were identified in entrainment samples; channel catfish, Lepomis spp., Pomoxis sp., walleye, white bass, white perch, and yellow perch.                        )
A total of 538 eggs were collected in entrai.nment samples with Cyprinidae (minnows) accounting for the greatest percentage (202 eggs, 37.5% of the total) (Table 6-34). Eggs of the perch family represented the second greatest percentage (137 eggs, 25.5% of the total) followed by trout-perch (101 eggs, 18.8% of the total) and Marone spp. (97 eggs, 18.0% of the total) which were similar in abundance. One lake whitefish egg was collected.
Clupeidae (including specimens identified as gizzard shad and alewife) was the dominant family represented in the 1991-1992 entrainment collections, accounting for 33.8% of the total larvae (Table 6-34). Gizzard shad was the dominant identifiable clupeid species accounting for 75.3% of the family total and 25.5% of the total larvae collected. The second most abundant larval ichthyoplankton group collected was the Percichthyidae family (represented by Marone spp., white perch and white bass larvae), which accounted for 23.2% of the total larvae. Marone spp. (species not identified) accounted for 73.2% of the Percichthyidae and 17.0% of the total larvae. White perch accounted for 26.5% of the Percichthyidae and 6.1 %
of the total Cyprinidae (including emerald and spottail shiner) and Percidae (including all
                                                                                                    )

identified larvae) ranked third (21.6%) and fourth (4.7%) in overall larval abundance.
Together, these four families accounted for 83.2% of the total larvae. Overall, 12.1 % of the total larvae collection of 23,379 or 2838 individuals were damaged and could not be identified.
The post yolk-sac life stage accounted for 76.0% of the total larvae (Table 6-35). The yolk-sac life stage was the second most abundant, constituting 11.5% of the total larvae, and juveniles accounted for 0.3% of.the total larvae. Overall, 12.2% of the larvae were damaged and unidentified to a life stage.
6.3.3 Diel Distribution of Icbthyoplankton The die! distribution of larvae collected at Fermi 2 showed no significant differences between the four 6-hr sample periods: day, dusk, night, and dawn. Table 6-36 presents abundance for the top eight taxa and total larvae .by life stage for each of the four 6-hr sampling periods.
The greatest number of larvae were collected during the day (6316 larvae or 27.0% of the total collection), followed closely by the night (6301 larvae, 27.0%), dusk (5902, 25.2%), and dawn (4860, 20.8%) periods, respectively.
Gizzard Shad.         Gizzard shad were collected primarily as post-yolk-sac with the die!
distribution of gizzard shad larvae dissimilar to that observed for total larvae. The greatest percentage of gizzard shad (38.4%) were collected at night and the lowest percentage (12.6%)
were collected during the day.
Cyprinidae. Diel distribution of cypriilids was highest during the day (490 yolk-sac larvae and
* 1501 post-yolk-sac larvae). Collection of cyprinids gradually decreased throughout the die! .
sample period, with approximately one third as many cyprinids collected during the dawn runs as during the day runs.
Morone spp.. Most Marone spp. (species not identified) were collected during the dawn period followed by dusk and day. Night collections were less than half of the other three periods.

)       Clupeidae. Diel distribution of the Clupeidae taxonomic group (species not identified) was dissimilar to that observed for gizzard shad; however, it was similar to that observed for total larvae. Numbers were highest during the day, followed by night, dusk, and dawn.
White Perch. Diel distribution of white perch was similar to that observed for the Marone spp. (species not identified). The largest number of white perch were collected during dawn followed by day and night. Dawn collections were twice as great as dusk collections.
Table 6-37 presents the die! distribution of eggs for each of the four 6-hr sampling periods.
Entrainment samples collected eggs from five taxa: Cyprinidae, Percidae, trout-perch, Marone spp., and lake whitefish. The greatest number of eggs were collected during the dusk periods, followed by day, night, and dawn. Table 6-38 presents the number of total ichthyoplankton entrained during each die] period for each taxa.
6.3.4 Biological Information on Dominant Species
  )   The top eight ichthyoplankton taxa based on abundance, with each taxon representing at least 1.0% of the annual total collection, accounting for 84.2% of the total number of ichthyoplankton collected and 95.6% of the total number of ichthyoplankton identified, were (in rank order): gizzard shad, Cyprinidae, Marone spp., Clupeidae, white perch, Percidae, Catostomidae, and lake whitefish. Biological information, including growth patterns based on length frequency data, is presented in the following sections.
Gizzard shad. The dominant ichthyoplankton !axon collected was gizzard shad, accounting for 24.9% of the total number collected in entrainment sampling.             Gizzard shad were identified in entrainment collections during the months of May through September. Length frequency information by month (Table 6-39), indicates that post-yolk-sac larvae constituted the greatest percentage of gizzard shad entrained during May through August, with the occasional collection of a juvenile. September collections produced one post-yolk-sac larvae and one juvenile. Total length (mm) ranged from a 4.8 mm post-yolk-sac larvae in June to a 35.0 mm juvenile in July.

Cyprinidae. Cyprinidae (species not identified) was the second most abundant taxon collected, accounting for 21.8% of the total number of ichthyoplankton collected. Cyprinidae were identified in entrainment collections from May through August. The family Cyprinidae was also the only taxon to be identified in all four life stages; eggs, yolk-sac, post-yolk-sac, and juveniles. Length frequency data (Table 6-40) indicate that yolk-sac larvae dominated in May and post-yolk-sac larvae dominated June through August. Total length ranged from 4.1 mm recorded in May to 21.9 mm recorded in June.
Morone spp .. The third most abundant taxon collected in entrainment monitoring was Marone spp. (species not identified) accounting for 17.0% of the total abundance. Marone spp. were collected during May through August, with the greatest concentration noted during July.
Length frequency data (Table 6-41) indicate that yolk-sac larvae dominated in May and post-yolk-sac larvae dominated June through August. Total length ranged from 2.5 mm recorded in May to 15.5 mm recorded in August.
Clupeidae. Clupeidae (species not identified) accounted for 7.8% of the total abundance and were collected during May through September. Post-yolk-sac, ranging in length from 4.4 mm recorded in July to 17.1 mm recorded in August (Table 6-42) was the only life stage identified in the entrainment collections.
White Perch. The fifth most abundant taxon collected in the entrainment samples was white perch, accounting for 6.0% of the total abundance. White perch were collected during June, July, and August. Length frequency data (Table 6-43), indicate that post-yolk-sac larvae constituted the greatest percentage of white perch entrained during June through August, with the occasional collection of a juvenile. Total length ranged from a 3.5 mm post-yolk-sac larvae in June to a 33.0 mm juvenile in July.
Percidae, Catostomidae, and Lake Whitefish. The next three taxa in abundance rank order were Percidae (2.9% total abundance), Catostomidae (2.1 % total abundance), and lake whitefish (1.7% total abundance). Percidae (Table 6-44) were collected during May through August, Catostomidae (Table 6-45) were collected during May and June, and lake whitefish

)     identified; eggs, yolk-sac, and post-yolk-sac. The greatest concentration of Percidae occurred in May, with post-yolk-sac larvae and eggs dominating. Yolk-sac and post-yolk-sac larvae were identified in the Catostomidae collections. The greatest concentration ofCatostomidae occurred in May, with yolk-sac larvae dominating in both May and June. Three life stages; eggs, yolk-sac, and post-yolk-sac were identified in the lake whitefish collections. The greatest concentration of lake whitefish occurred in April, with yolk-sac larvae dominating.
6.3.5 Estimated Annual Entrainment Annual entrainment abundance at the Fermi 2 Power Plant was estimated using the entrainment rate calculated based on the number collected and the volume of water sampled, and annual plant withdrawal. Estimates were calculated for weekly, monthly, and annual totals. Estimates for the top eight taxa and their respective life stages are also given. The results are presented below.
Total estimated ichthyoplankton entrainment at the Fermi 2 intake between 1 October 1991 and 30 September 1992 was 2,955,694 ichthyoplankton (2,883,326 larvae and 72,367 eggs).
The greatest number of larvae were estimated entrained during June and July, with 1,261,302 and 848,955 larvae, respectively (Table 6-47). No ichthyoplankton were estimated entrained during October 1991 through February 1992. Total entrainment by week is presented in Appendix H.       Cyprinidae was the dominant taxon entrained, with an estimated annual entrainment of 659,985 larvae, or 22.9% of the larval total. Marone spp. (577,319 larvae, 20.0% of the larval total), gizzard shad (560,816 larvae, 19.5% of the larval total), Clupeidae (252,487 larvae, 8.8% of the larval total), white perch (178,167 larvae, 6.2% of the larval total), Percidae (70,911 larvae, 2.5% of the larval total), Catostomidae (61,745 larvae, 2.1 %
of the larval total), and lake whitefish (50,502 larvae, 1.8% of the larval total) completed the top eight larvae taxa entrained in rank order, respectively. Damaged and unidentified larvae comprised 12. 7% of the larval total.
Four life stages were identified in the entrainment collections: eggs, yolk-sac, post-yolk-sac, and juveniles. The dominant ichthyoplankton life stage collected was post-yolk-sac, with an estimated annual entrainment of 2,165,792 or 75.1 % of the annual larval total. (Table 6-48).

CHAPTER 7 DISCUSSION OF PROGRAM RESULTS 7.1 PHYSICAL AND CHEMICAL PROGRAM Physical and chemical water quality parameters were recorded with each entrainment and impingement sample collected during the 12-month Fermi 2 Power Plant intake monitoring program, and were obtained from government monitoring stations in the vicinity of the power plant. Parameters recorded or obtained from government agencies included Lake Erie water temperature, transparency, pH, and elevation. In addition, weather conditions including barometric pressure, air temperature, wind speed and direction, and percent cloud cover were recorded at the beginning and end of each impingement sample collection.
Lake Erie water level information indicated a general increase in water level over the 12-month study period. Daily variability in water level was greatest during the fall-early winter
  )
months as a result of standing waves or seiches related to winter storms. The greatest variability in lake level was noted between 28 October and 2 November 1991 when over the five day period the recorded lake level declined from a high of 174.42 m (572.24 ft) to a low of 173.01 m (567.61 ft), a change of 1.41 m (4.63 ft). Very little daily variability in Lake level was noted during spring and the summer months.
Lake Erie water temperature demonstrated a pattern characteristic of north temperate waterbodies with a relatively rapid decrease in temperatures during the fall months, consistent low temperatures during the winter months, a gradual increase during the spring months, and summer month high values. Daily water temperature data recorded at the Fermi 1 intake indicated numerous changes of several degrees occurring over a few days. Overall, there was no consistent pattern evident between short-term changes in water temperature and changes in lake level.
Water transparency measured with a Secchi disk in the Fermi 2 intake canal demonstrated
    ) a wide degree of variability over the study period. The greatest transparency was recorded 7-1 Lawler, Matusky & Skelly Engineers

during January and February when ice cover was reported on the Lake which minimized the potential for storms to disturb the nearshore bottom sediments. The lower transparency values were generally recorded at the higher wind speeds which indicates storm activity that results in nearshore sediment disturbance.
No major change in pH was noted over the study period. Over the 12-month study period the pH averaged 8.3 ranging from 6.9 to 8.9.
Three velocity surveys were conducted at the Fermi 2 Power Plant during the 12-month study period. Two surveys, the winter survey (9 December and 19 February) and the spring survey (29 May), were conducted with three GSW pumps operating, and the summer survey (5 August) was conducted with four GSW pumps operating. For the one year study (October 1991-September 1992) three GSW pumps operated on 68.0% of the days and four GSW pumps operated on 22.2% of the days. Velocity profiles conducted in front of the two traveling screens indicated that the greatest percentage of the flow was. passed through the bottom half of each screen generally corresponding to the height of the openings upstream and downstream of the screens. Considering only the bottom 3.3m of the two screens for the           )
filtration of water, the average velocity at the face of the two screens under three pump operation would be approximately 7.1 cm/s (0.23 fps), and the average velocity under four pump operation would be approximately 9.5 cm/s (0.31 fps). In general, the average velocities obtained from the velocity profiles conducted at the face of the two screens correspond to the calculated values. Actual velocities exhibited a wide degree of variability with the readings ranging from 0.0 to 12.4 cm/s under three pump operation and from 0.0 to 12.0 cm/s under four pump operation. The higher velocities were normally recorded from just below mid depth of the screenwell and near the centerline of the intake, ie., next to the screenwell dividing wall.
Calculated and actual average velocities determined at the entrance to the intake canal were similar under both three and four pump operation. The higher velocities were generally recorded from the water layer bounded by the 0.6 m (2.0 ft) and 1.2 m (4.0 ft) depth readings, and the lowest velocities were always recorded along the bottom of the canal.
                                                                                                   )

7.2 IMPINGEMENT MONITORING PROGRAM Impingement collections were conducted over 53 24-hr periods between 1 October 1991 and 30 September 1992. The two intake traveling screens were operating during 37 of the 53 sample dates, and for all samples collected during the period April through September 1992.
For the 16 dates when only one of the two screens was operating, the impingement abundance and biomass data were doubled to account for impingement on the non-operating screen.
A total of 1944 fish representing twenty-three species and nine families were collected and identified from the Fermi 2 traveling screens. The total weight of the impinged fish was 46. 7 kgs. The estimated annual impingement at the Fermi 2 Power Plant is 13,699 fish, with a total estimated biomass of 329.8 kgs. The greatest number of fish were impinged during the fall and winter months with the annual peak recorded during February and March. The lowest number were impinged during the summer months of July, August, and September. The
)   seasonal pattern of estimated fish biomass mirrored the pattern of fish abundance.
The dominant fish species collected was the gizzard shad, with an estimated annual impingement of 9798 or 71.5% of the annual estimated total abundance. Gizzard shad also ranked first in estimated biomass with 229.5 kgs or 69.6% of the annual estimated total.
Yearling gizzard shad were the dominant fish impinged during the peak February and March period, and young-of-year gizzard shad comprised the greatest percentage of the November and December impingement catch. Young gizzard shad concentrate in the shallow inshore waters near harbors and river mouths during the fall and winter months (Scott and Crossman 1973, Eisele and Malaric 1977) which accounts for its dominance in the Fermi 2 impingement samples during this period. Since the gizzard shad is at the limits of its northern range in Lake Erie, it is very susceptible to changes in water temperature especially during the cold water months. Comparing the impingement of gizzard shad to changes in water temperature over the 1991 and 1992 study period indicates greater impingement at the colder water temperatures; however, the relationship was not highly correlated (r    = -0.478).

The white perch was the second most abundant species impinged with an estimated total of              )
926 and an estimated biomass of 5. 7 kgs. White perch were collected during the fall and winter period similar to gizzard shad with the majority of the specimens impinged being young-of-year and yearlings. Other fish species that were identified from the intake traveling screens and which comprise more than one percent of the estimated annual total were rock bass, freshwater drum, emerald shiner, bluegill, yellow perch, white bass, spottail shiner, and trout-perch. For the major species, impingement was generally limited to young-of-year and yearlings, with adults of the rock bass and freshwater drum the exceptions.
7.3 POSITRAVELING SCREEN JUVENILE ENTRAINMENT PROGRAM Replicate vertical net hauls were conducted downstream of each traveling screen on an hourly schedule during each date on which entrainment samples were collected. A total of 13,547 juvenile fish were coltected representing 15 species and 10 families. The dominant species collected was the gizzard shad accounting for 59.4% of the total. Spottail shiner was the second most abundant species collected (18.0% of the total), with yellow perch (6.6%) and emerald shiner (5.3%) ranking third and fourth, respectively. With the exception of emerald
                                                                                                      )
shiner which exhibited two distinct periods of abundance; early to mid spring and summer, the collection of juveniles in posttraveling screen entrainment samples was limited to the late spring and summer months.
Similar species composition was observed in the samples collected downstream of the two traveling screens; however, there was a difference in the abundance of the major species with a greater, number collected at station Sl (downstream of Screen B) than collected at station S2 (downstream of Screen A). Of the total posttraveling collection of 13,547 fish, 9653 (71.3%) were collected at S1 and 3894 (28.7%) were collected at S2. For the four major species accounting for 89.3% of the total catch, 71.0% of the gizzard shad (5711 individuals),
83.1 % of the spottail .shiner (2031 individuals), 71.8% of the yellow perch (641 individuals),
and 48.5% of the emerald shiner (349 individuals) were collected at station Sl. Over the 12-month study period the greater number of juvenile fish collected at station Sl is consistent.
Two possible explanations for the greater number of juvenile fish collected behind Screen B is the offset in the GSW pumps downstream of the sampling locations with four of the five
                                                                                                    )

pumps located on the Screen B side of the intake or the small fish tend to avoid the more turbulent conditions noted behind screen A caused by the intermittent operation of the make-up pumps.
7.4 ICHTHYOPLANKTON ENTRAINMENT MONITORING PROGRAM Entrainment collections were conducted over 30 24-hr periods between 1 October 1991 and 30 September 1992. Collections were made at both entrainment locations on 29 of the 30 sample dates, with .the 10-11 March 1992 sample date only having been sampled at the E2 location. Each sample date was divided into four 6-hr die! periods.
A total of 538 identifiable fish eggs and 23,379 larvae representing 28 taxa (identified to either family, genus or species level) and 13 families were collected from the Fermi 2 intake.
The estimated annual entrainment at the Fermi 2 intake is 72,367 eggs and 2,883,326 larvae.
Eggs were entrained during April through July with the greatest estimated entrainment (44,074 eggs; 60.9% of the total) recorded during May. The greatest number of larvae were
)    entrained during the summer months with peak entrainment (1,261,302 larvae: 43.7% of the total) recorded during June. No ichthyoplankton (eggs or larvae) were entrained during the period October through February. The dominant ichthyoplankton taxon collected for both eggs and larvae was Cyprinidae (species not identified), with an estimated annual entrainment of 690,429 or 23.4% of the annual total abundance. Cyprinid eggs accounted for 42.1 % of the total egg estimate and cyprinid larvae accounted for 22.9% of the total larval estimate.
Post yolk-sac larvae dominated the collection of Cyprinidae accounting for 65.8% of the total wih yolk-sac larvae accounting for 33.8% of the total.           For each of the major taxa, entrainment was generally limited to post yolk-sac larvae with yolk-sac larvae of the catostomids and lake whitefish the exception.
Ichthyoplankton were identified in entrainment samples from the last week of March through the second week of September. Lake whitefish was the only species identified in March and April, and did not appear in collections from May through September. Lake whitefish spawn in the fall and their eggs develop for about 4 months then hatch in March or April (Goodyear, Edsall, Dempsey, Moss, and Polanski 1982). Entrainment collections in May were

Cyprinidae eggs were collected from May through early July, although they were collected in low numbers after 27 May (Appendix G). A peak average density of just under 12 per 1,000 m3 was observed on 26-27 May. Yolk-sac larvae were collected from mid-May into early August, with a peak average density of just under 88 per 1,000 m3 observed on 19-20 May.
The majority of Cyprinidae collected at Fermi 2 were post yolk:sac larvae. They were collected from mid-May through the end of August, with peak average densities of 202 per 1,000 m3 observed on 16-17 June.
Marone spp. eggs were collected from mid-May through early July, with a peak average density of just over 5 per 1,000 m3 observed on 12-13 May. Marone spp. yolk-sac larvae were only collected on 12-13 May, with an average density of just over 3 per 1,000 m3* The majority of Marone spp. ichthyoplankton collected at Fermi 2 were post yolk-sac larvae. They
                                                                                                     )
were collected from mid-May through the end of August, with peak average densities of 341 per 1,000 m3 observed on 14-15 July.
Gizzard shad post yolk-sac larvae were collected from the end of May through mid-September. A peak average density of just over 483 per 1,000 m3 was observed on 23-24 June. Juvenile gizzard shad were collected in July, August, and September, however; the densities were less than 1 per 1,000 m3*
Peak ichthyoplankton entrainment occurred during the warm water spring and summer months which was also the period of highest Fermi 2 cooling water withdrawal.

Executive Summary The purpose of this report is to summarize the current data collected as part of the Aquatic Ecology Survey for Detroit Edison Companys (DECo) proposed Fermi 3 Nuclear Generating Station to be located near Newport (Frenchtown Charter Township) in Monroe County, Michigan. Data collected in this study are in support of DECos Combined Operating License Application (COLA) to the Nuclear Regulatory Commission (NRC).
The Fermi site is located on the Western Basin of Lake Erie between the Swan Creek and Stony Creek watersheds. Aquatic resources associated with the site include: Lake Erie; Swan Creek; on-site waterbodies; and waters within the Detroit River International Wildlife Refuge (DRIWR). The on-site waterbodies consist of the internal canal system, quarry lakes, and the cooling tower circulating water reservoir. Waterbodies in the DRIWR portion of the site include the south lagoon, north lagoon, and a small isolated pond. In addition to the waterbodies, wetlands are associated with on-site waterbodies and low lying areas.
The purpose of the aquatic survey was to collect data over a one-year period in the vicinity of the site in order to supplement the aquatic data included in the Environmental Report of the COLA. The assessment was designed in accordance with discussions with DECo and the NRC during the projects T-1 and T-2 meetings.
Current species richness and relative abundance for fishes and macroinvertebrates were determined in the waterbodies located on-site, within the DRIWR, and adjacent to the site in Lake Erie and Swan Creek. Fish species impacted by impingement and entrainment as part of the current operation of the General Service Water Pump House (GSWPH) for Fermi 2 were identified to compare current fish impingement (I) and entrainment (E) data to historical data. Impingement and entrainment rates were calculated to assist in determining potential impacts to aquatic resources associated with the proposed expansion project.
Nine representative sampling locations were chosen from a variety of aquatic habitats onsite and adjacent to the Fermi site. The locations selected for this study include two on Lake Erie immediately adjacent to the Fermi site, one in Swan Creek, three in the internal canal system, two quarry ponds, and the isolated pond. These locations were selected based on their ability to represent the aquatic resources adjacent to the site and those areas that are in proximity to the proposed new facilities and construction areas. Samples of fish communities and benthic macroinvertebrates were collected at randomly selected locations within each sample area. The study took place from July 2008 through July 2009.
Monthly samples were collected over a four to five day period using a variety of gears: dip nets and plankton nets for impingement and entrainment sampling; gill nets, seines, hoop nets, minnow traps, and electroshocking to determine fish populations in the various aquatic habitats; and dip nets for sampling benthic communities in the same aquatic habitats. Fish were collected according to current fisheries techniques as described by Murphy and Willis (1996). Upon retrieval of each sample gear, all fishes were identified to the lowest taxonomic level and enumerated. Up to 50 randomly selected individuals of each species were measured (total length) to the nearest millimeter. The total length for each fish was measured from the tip of the snout to the tip of the tail. Benthic macroinvertebrates were sampled monthly from July 2008 through June 2009 in principal habitat areas associated with each of the nine aquatic sampling locations. Principal habitats included areas with aquatic vegetation and areas consisting of soft silt and/or detrital substrates. A 12-inch D-frame dip net with 500&#xb5;m mesh was pulled through one linear meter at a depth of two inches into the substrate.
This method closely follows the methods outlined by the EPA field operations manual for the survey of the Nations Lakes.
Impingement samples were collected once per month, for a 24-hour period, from August 2008 through July 2009 at the existing Fermi 2 GSWPH located on Lake Erie. No sample was collected in April 2009 due to excess debris at the intake structure. Entrainment samples were collected once per month from July 2008 through November 2008, March 2009 and July 2009, and twice per month April 2009 through June 2009. No entrainment samples were collected December 2008 through February 2009 due to icing conditions.
Impingement and entrainment data were evaluated to determine the total number of individuals collected, the ES-1

life stage of each individual (entrainment only), the percent composition, and an impingement/entrainment rate for each sample.
Data were evaluated on a monthly basis to determine monthly and seasonal shifts in abundance and diversity.
Based on the data presented in the interim report, it was agreed upon by DECo and the NRC, that several aspects of the sampling program be modified. These modifications consisted of changes to the impingement and entrainment sampling program and the fish and macroinvertebrate sampling program. Entrainment sampling was modified to include a two pump system that allowed for the collection of entrainment samples at multiple depths, near surface and near bottom. These changes applied to samples collected in April, May, June and July 2009. An additional entrainment sample was added in March 2009 based on historical findings that indicated whitefish had been entrained during March. One sample was added each month from April through June 2009 to collect additional data during peak recruitment season. The fish and macroinvertebrate sampling program was modified from nine to five sample locations when the South Quarry, North Quarry, Isolated Pond and Isolated Central Canal were removed from the sampling plan. Discussions with DECo and the NRC along with evaluation of the data presented in the interim report indicated that these locations are home to fairly stable fish populations, both in terms of abundance and species richness, and whose fish populations are not expected to undergo dramatic fluctuations.
Representative important species (RIS) include both state and federally listed threatened and endangered species and those with commercial and recreational value. Several fish (creek chubsucker, silver shiner, pugnose minnow, channel darter, river darter and southern redbelly dace) and mollusks (white catspaw, northern riffelshell, snuffbox, round hickorynut, salamander mussel and purple lilliput) are listed as endangered in Monroe County by the state of Michigan (MDNR). Only the northern riffelshell is federally listed (USFWS) as endangered in Monroe County. The lake sturgeon, eastern sand darter, sauger and wavy-rayed lampmussel (mollusk) are listed as threatened in Monroe County by the state of Michigan.
Commercial fish harvest in the Michigan waters of Lake Erie in 2007 consisted of 13 species of fish, weighing a total of 1,058,253 pounds with an estimated value of $398, 253. Total catch was dominated by three types of fish: the common carp, gizzard shad and buffalo. Other species harvested included channel catfish, white bass, freshwater drum, goldfish, white perch, whitefish and others, including bullheads, suckers, quillback and chub (Thomas, 2008). Important recreational species in the western basin of Lake Erie include both native and non-native species. Sport fishing harvest (non-charter) in the Michigan waters of Lake Erie in 2007 consisted of approximately 369,624 fish, which were dominated by yellow perch and walleye. Other species harvested by sport-fishermen included white perch, channel catfish, white bass, freshwater drum, largemouth bass, smallmouth bass and rainbow trout (Thomas, 2008).
Eleven impingement samples were collected during the sampling period resulting in a total of 101 fish collected.
The December 2008 sample yielded the greatest number of fish (34) while the June 2009 and July 2009 samples yielded the fewest fish (1). Fish composition was dominated by gizzard shad (39%), emerald shiner 3                        3 (29%), white perch (10%), and bluegill (7%). Impingement rates (#/m ) ranged from 1.9E-4 fish/m in December 3              1 2008 to 4.3E-6 fish/m in June 2009. The average annual impingement rate for all species collected in the 11 3
samples from August 2008 through July 2009 was 4.6E-5 fish/m . Of the 15 species identified, the gizzard shad 3
had the highest impingement rate (1.8E-5 fish/m ). No federally or state listed threatened or endangered species were collected.
It is estimated that 3,102 fish are impinged annually at the Fermi 2 GSWPH with intake pumps at operational capacity (actual intake volumes provided by DECo were used to determine monthly operational intake). Of those, gizzard shad (1,204) and emerald shiner (889) are expected to be the most commonly impinged fish.
December (1,054) and March (806) have the highest estimated impingement numbers with Fermi 2 intake pumps at operational capacity. In addition, the impingement rates calculated at Fermi 2 were used to estimate 1                                                                                         -4 Impingement rates are expressed in scientific notation; 1.9E-4 is equivalent to 1.9x10 ES-2

maximum impingement at the proposed Fermi 3 facility. It is estimated that 3,110 fish will be impinged annually at the Fermi 3 facility with intake pumps operating at maximum capacity (32,264 gpm). Of those, gizzard shad (1,246) and emerald shiner (916) are expected to be the most commonly impinged fish. December (1,090) and March (851) have the highest estimated impingement with Fermi 3 pumps operating at maximum capacity.
Entrainment samples were collected during 10 months from July 2008 through July 2009. A total of 1286 organisms were entrained, which included 12 identified taxa, 74 unknown eggs, and 2 unknown centrarchid larvae. The May sample yielded the greatest number of fish eggs/larvae (533) while both November and March yielded the lowest number (0). Sample composition was dominated by gizzard shad, emerald shiner, bluntnose 3                     3 minnow, and yellow perch. Entrainment rates (fish eggs + larvae/m ) ranged from 4.82/m in July 2009 to 3
0.00/m in November 2008 and March 2009. The average annual entrainment rate for all species collected from 3
July 2008 through July 2009 was 0.98/m . Of the 12 taxa identified in entrainment samples, the gizzard shad 3
reflected the highest entrainment rate at 0.36/m while the white perch and the brook silverside represented the 3
lowest entrainment rates at 0.0015/m . No eggs or larvae of federally or state listed threatened or endangered species were collected.
It is estimated that 62,566,648 fish (3,940,823 eggs and 58,625,825 larvae) are entrained annually at the Fermi 2 GSWPH with intake pumps at operational capacity (actual intake volumes provided by DECo were used to determine monthly operational intake). Of those, 33,852,880 are expected to be entrained in July with gizzard shad (30,238,133) being the most commonly entrained fish each year with Fermi 2 intake pumps functioning at operational capacity. In addition, the entrainment rates calculated at Fermi 2 were used to estimate maximum entrainment at the proposed Fermi 3 facility. It is estimated that 54,776,573 fish (3,450,157 eggs and 51,326,416 larvae) will be entrained annually at the Fermi 3 facility with intake pumps operating at maximum capacity (32,264 gpm). Of those, the gizzard shad (25,106,899) and the emerald shiner (9,461,210) are expected to the most commonly entrained fish. July (27,896,935) has the highest estimated entrainment with Fermi 3 pumps operating at maximum capacity.
A total of 14,885 fish consisting of 52 species were captured at the nine sampling sites from July 2008 through June 2009. Of the fish collected, goldfish, gizzard shad, bluegill, and emerald shiner accounted for 61% with 48 species accounting for the remaining 39%. The greatest number of fish, 3,856, were collected at the Lake Erie
- South Lagoon site (LE2-A). Goldfish, gizzard shad and emerald shiner dominated these samples. The Isolated Pond (IP-A) reflected the fewest number of total fish with only 11. The greatest number of fish were collected in August 2008, 4,649 total fish, while only 447 fish were collected in November 2008. The Lake Erie -
South Lagoon (LE2-A) sample had the greatest number of fish species (38) and the Isolated Pond had the fewest number of fish species (4). No federally or state listed threatened or endangered species were collected.
Macroinvertebrate sampling produced a total of 5,049 individuals representing 19 orders from the nine sampling sites from July 2008 through June 2009. Diptera, Ephemeroptera, Amphipoda, and Tubificida accounted for 75% of individuals collected. The other 15 orders accounted for the remaining 25%. Diptera was mostly comprised of Tanytarsus sp. while Tubificida was mostly comprised of Naidinae and Tubificinae. Swan Creek (SC-A) sample site had the greatest number of individuals collected with 790 while the Lake Erie 1 (LE1-A) sample site had the fewest number of individuals with 260. The Isolated Pond (IP-A) sample had the greatest number of taxa captured (27) in both September 2008 and October 2008 and Lake Erie - Intake (LE1-A) had the fewest number of taxa captured (0) in the May 2008 sample.
There were no federally and/or state listed threatened or endangered species collected in this study. The most common commercially important species collected were goldfish, gizzard shad, common carp, white perch and bigmouth buffalo. Commercial species commonly found in impingement samples included gizzard shad and white perch, while the most prominent commercial species in entrainment samples were gizzard shad, bigmouth buffalo and freshwater drum. The most common recreationally important species collected were white perch, largemouth bass and yellow perch. Recreational species commonly found in impingement samples included white perch and smallmouth bass while the most prominent recreational species in entrainment samples were yellow perch and freshwater drum.

1.0       Introduction This report summarizes data collected as a component of the Aquatic Ecology Survey for Detroit Edison Companys (DECo) proposed Fermi 3 Nuclear Generating Station to be located near Newport (Frenchtown Charter Township) in Monroe County, Michigan, Figure 1. Data collected in this study are in support of DECos Combined Operating License Application (COLA) to the Nuclear Regulatory Commission (NRC).
The Fermi site is located on the Western Basin of Lake Erie between the Swan Creek and Stony Creek watersheds. The site consists of approximately 1,120 acres of developed and undeveloped land with approximately 650 acres of land being designated as part of the Detroit River International Wildlife Refuge (DRIWR). Aquatic resources associated with the site include: Lake Erie; Swan Creek; on-site waterbodies; and waters within the DRIWR. The on-site waterbodies consist of the internal canal system, quarry lakes, and the cooling tower circulating water reservoir. Waterbodies in the DRIWR portion of the site include the south lagoon, north lagoon, and a small isolated pond. Wetlands are also present and are associated with several of the on-site waterbodies.
The Fermi 2 Power Plant utilizes a closed-cycle condenser cooling water system with two natural draft cooling towers. Water for the operations and the cooling system is withdrawn through a shoreline intake structure located on a dredged canal near the shoreline of Lake Erie. The maximum total plant withdrawal, from Lake 3
Erie, is 65,000 gpm (246.0 m /min). The pumping facility consists of five general service water (GSW) pumps, 3
each with a capacity of 7,000 gpm (26.5m /min) and two make-up water pumps, each with a capacity of 15,000 3
gpm (56.8m /min). Only four (4 x 7,000 gpm) of the GSW pumps operate at any one time while the fifth pump serves as a standby pump which is used only when one of the other pumps is inoperable. Similarly, only one of the 15,000 gpm make-up water pumps is in operation at any one time. Actual Fermi 2 intake volumes were provided by DECo for each sampling month. These operational volumes were used in estimating annual impingement and entrainment abundance at the existing Fermi 2 plant.
The Fermi 3 Power Plant proposes to utilize an intake system similar to that of Fermi 2. The Fermi 3 intake system will consist of three GSW pumps (each rated at 16,132 gpm). Similar to Fermi 2, one of these pumps will be utilized as a standby pump which operates only when one of the primary units is inoperable. Therefore, for the purpose of evaluating maximum impingement and entrainment abundance at Fermi 3, only two of the GSW pumps were considered (32,264 gpm).
The primary objective of the aquatic assessment was to collect current data over a one year period to supplement the aquatic data included in the Environmental Report of the COLA. The assessment was designed in accordance with discussions with DECo and the NRC during the projects T-1 and T-2 meetings.
The final study design was ultimately reviewed by the NRC prior to sampling. The goals of the study were to:
* Determine fish species impacted by impingement and entrainment as part of the current operation of the General Service Water Pump House (GSWPH) for Fermi 2;
* Determine current species richness and relative abundance for fishes and macroinvertebrates in the waterbodies located on-site, within the DRIWR, and adjacent to the site in Lake Erie and Swan Creek;
* Compare current fish impingement (I) and entrainment (E) data to historical data to determine potential impingement and entrainment rates; and
* Identify potential impacts to aquatic resources associated with the proposed expansion project.
In order to meet the objectives of the aquatic assessment, a study was designed to take place from July 2008 through July 2009 in which nine representative sampling locations were chosen from a variety of aquatic habitats onsite and adjacent to the Fermi site. The locations selected for this study include two on Lake Erie 1

immediately adjacent to the Fermi site, one in Swan Creek, three in an internal canal system, two quarry ponds, and the isolated pond. Table 1 provides a description of the observed aquatic habitat at each sampling location.
2.0        Materials and Methods Nine locations were selected for aquatic resource characterization. Impingement and entrainment sampling took place at the Fermi 2 GSWPH intake facility, Figure 2. Locations were selected based upon their ability to represent the aquatic resources adjacent to the site and those areas that are in proximity to the proposed new facilities and construction areas. Fish communities and benthic macroinvertebrates were collected at randomly selected locations within each sample station. The sample stations include:
* North Canal (CN-A);
* Swan Creek (SC-A);
* Lake Erie - Intake (LE1-A);
* Lake Erie - South Lagoon (LE2-A);
* South Canal (CS-A);
* South Quarry (SQ-A);
* North Quarry (NQ-A);
* Isolated Pond (IP-A); and
* Isolated Central Canal (IC-A).
The Great Lakes Environmental Center (GLEC) located in Traverse City, Michigan conducted the aquatic resource sampling. GLEC has extensive experience completing I/E studies on Lake Erie and Lake Michigan, including cooperation with the Michigan Department of Natural Resources (MDNR) and the Environmental Protection Agency (EPA) to develop sampling protocols for aquatic systems in Michigan and other states in the northeast. Appendix A provides photographic documentation of sampling activities at the Fermi site.
A one year, monthly, sampling program was established to characterize species richness and diversity within each aquatic resource. The following section outlines the various sampling programs, initiated in July 2008 while modifications to the sampling program are described in section 3. Monthly samples were collected during a four to five day period using a variety of gear: dip nets and plankton nets for impingement and entrainment sampling; gill nets, seines, hoop nets, minnow traps, and electroshocking to determine fish populations in the various aquatic habitats; and D-frame dip nets for sampling benthic communities in the same aquatic habitats.
Due to site-specific environmental constraints, biological surveys were restricted to certain months of the year.
Therefore, aquatic samples were collected over a one year period during those months when sampling accessibility was not limited by the icing of waterbodies or excessive aquatic vegetation. See Table 2 for a summary of all sampling events conducted at each location by date.
2.1        Impingement and Entrainment Impingement Collection Impingement samples were collected monthly over a 24-hour period (12 hour intervals) from August 2008 through July 2009 at the existing Fermi 2 GSWPH located on Lake Erie. A total of 11 samples were collected with no sampling in April due to excess debris on the screens. Samples were collected from the trash/debris sluiceway using modified sampling dip nets fitted with 1/4 mesh. Prior to the initial sample collection, the 2

traveling screens were scheduled to run for 30 minutes to wash and clear the screens of all existing debris and organisms. The screens were then left idle over the next 12 hours for the first impingement period. At 12 hours, dip nets were placed in the sluiceway and the screens were run once more for 30 minutes to ensure more than one complete revolution and complete washing of organisms and debris. Samples collected during this time were documented for the 12-hour period. This process was subsequently repeated to yield a combined sample period of 24 hours for each sampling event. Organisms collected from the screens were rinsed into dip nets and sorted by species, then total length (TL) was measured to the nearest millimeter.
Entrainment Collection Entrainment samples were collected on the following schedule:
* Once monthly: July 2008 through November 2008, March 2009, and July 2009;
* Twice monthly: April 2009 through June 2009; and
* No samples scheduled due to icing: December 2008 through February 2009.
Entrainment samples were collected at 6-hour intervals over a 24-hour period for a total of four samples per event. To characterize diel variations, two of the samples represented day time and two represented night time collections. Samples were collected using a trash pump system located in front of the trash racks at the GSWPH. The pump system filters water through a 500m mesh plankton net fitted within a buffer chamber. A 6-horsepower pump fitted with a 3-inch hose was lowered into the water column to a depth of approximately 12 feet (middle of the water column). The pump was run for approximately 1 to 2 hours to collect a prescribed volume of water (approximately 6, 600 gal/sampling period) per each six-hour sampling interval so that a total known volume of water was pumped during a 24-hour period. A second pump with identical specifications was added to collect samples across the entire water column during April 2009 through June 2009 samples. Fish eggs and larvae were removed from the samples collected by plankton net, counted and identified to the lowest possible taxon.
Analysis of Impingement and Entrainment Data The impingement and entrainment data were evaluated to determine the total number of individuals collected, the species composition, and impingement/entrainment rates. The following analyses were performed in each case:
* Calculation of impingement and entrainment rates by sample, averaged by year;
* Calculation of estimated abundance at operational capacity; and
* Calculation of estimated abundance at maximum capacity.
Impingement rates were calculated for each 24 hour sample by dividing the total number of fish collected in the 3
sample by the total volume (m ) of water withdrawn by the facility during the sample. Table 3 details the monthly flow volumes provided by DECo for each sample month. These monthly flow volumes were used to estimate the volume withdrawn during each 24 hour sample. An average annual impingement rate was determined by dividing the total number of fish collected across the 11 samples by the total volume of water 3
sampled. Impingement rates are provided as total number of fish collected per m of water sampled. There was no sample collected in April and thus its flow volume is not utilized in the calculation of the average annual impingement rates.
Entrainment rates were calculated for each sample by dividing the total number of fish (eggs + larvae) collected 3
during each sample by the total volume of water (m ) pumped during sample collection by the sampling pump(s). An average annual entrainment rate was determined by dividing the total number of fish collected 3
across the 9 monthly samples by the total volume of water sampled (m ). Entrainment rates are provided as 3
total number of fish per m of water sampled.

3 Impingement/Entrainment Rate = # organisms collected/volume of water sampled (m )
Using the rates described above, an estimate of total impingement/entrainment abundance was calculated using two approaches: operational capacity and maximum capacity.
The estimated impingement/entrainment abundance at operational capacity was calculated by first recording the volume of circulating water from the operational pump usage at Fermi 2 throughout the 24-hour sample 3
collection, Table 3. The sample impingement/entrainment rate (#/m ) was then multiplied by the operational volume withdrawn by Fermi 2 each month to estimate monthly abundance at Fermi 2. The sum of the monthly abundance figures is provided as an estimate of operational annual impingement and entrainment at the existing Fermi 2 Power Plant.
3                               3 Estimated Abundance at Operational Capacity = rate (#/m ) x operational withdrawal (m )/month The estimated impingement/entrainment abundance at maximum capacity was calculated by first determining the volume of water that could be withdrawn by Fermi 3 with intake pumps operating at maximum capacity.
Table 4 provides maximum capacity flow volumes at Fermi 3 by month. The sample impingement/ entrainment 3
rate (#/m ) was then multiplied by the maximum capacity (34,264 gpm) at Fermi 3 each month to estimate monthly abundance. The sum of the monthly abundance figures is provided as an estimate of maximum annual impingement and entrainment at the proposed Fermi 3 Power Plant.
3                             3 Estimated Abundance at Maximum Capacity = rate (#/m ) x maximum withdrawal (m )/month 2.2       Fish Community The nine representative sampling stations were sampled once per month at randomly selected locations within each station, Figure 2. Fish were collected using current fisheries techniques as described in Murphy and Willis (1996). These gears are routinely used in fisheries sampling programs throughout North America and include:
gill nets; hoop nets; minnow traps; bag seines; and electroshocking. These gears were used to collect fish within the varying habitats associated with each aquatic resource. Multiple sampling gears were selected to allow for thorough sampling coverage of the different life stages of fish. Due to the diversity of aquatic habitat sampled and the amount of vegetative cover within each aquatic resource some sample gears could not be used at specific locations. Table 5 provides a summary of sample locations and the types of gears utilized for each. Electroshocking was employed at all locations except LE1-A (seines) and IP-A (minnow traps and hoop nets). Gill nets (NQ-A and SQ-A) and seines (LE1-A) were used to supplement the electrofishing effort at those specified locations.
Upon retrieval of each sample gear, all fishes were identified to the lowest practicable taxonomic level and enumerated. A maximum of 50 randomly selected individuals of each species were measured (total length) to the nearest millimeter. The total length of each fish was measured from the tip of the snout to the tip of the tail.
No samples were collected during the winter months from December 2008 through March 2009 due to environmental constraints associated with the icing of waterbodies.

2.3      Macroinvertebrate Community Benthic macroinvertebrates were sampled monthly in principal habitat areas associated with each of the nine aquatic sampling locations. Principal habitats included areas with aquatic vegetation and areas where the benthic substrate consisted of soft silt and/or detritus materials. A 12-inch D-frame dip net with a 500&#xb5;m mesh was pulled for one linear meter at a depth of two inches into the substrate. Samples were washed into a 500m mesh sieve bucket, and subsequently rinsed into a one liter plastic jar and preserved with 95% ethanol. This method closely follows the methods outlined by the EPA Field Operations Manual (2007). Benthic invertebrates were identified to the lowest practicable taxa and data were used to evaluate species richness and aquatic biodiversity.
No samples were collected during the winter months from December 2008 through March 2009 due to environmental constraints associated with the icing of waterbodies.
2.4      Representative Important Species As a part of the COLA application issued to the NRC, representative important species (RIS) with the potential to occur in the vicinity of the Fermi site were addressed. While no sampling locations or methods were modified to sample specifically for RIS, the study evaluated their potential occurrence. The presence or absence of the RIS species was documented through the sampling methods described throughout section 2. Representative important species (RIS) include both state and federally listed threatened and endangered species and those with commercial and/or recreational value. The following section describes the threatened and endangered aquatic species in Monroe County, Michigan as well as the state of the commercial and recreational fisheries in the Michigan waters of Lake Erie. For a complete life history of each of the representative important species discussed in this section, including spawning areas, nursery ground, food habits, feeding areas, wintering areas, and migration routes, see Appendix B.
Threatened and Endangered Species Federally and state listed aquatic fish and mollusk species with the potential to occur in the western basin of Lake Erie and/or other aquatic habitats within and adjacent to the Fermi Site in Monroe County, Michigan, are provided in Table 6. Threatened and endangered species lists prepared by the USFWS (federal level) and the MDNR (state level) were reviewed in order to develop the list.
Commercial Species Lake Erie supports one of the largest freshwater commercial fisheries in the world, with the majority of commercial fishing based on the Canadian border. Commercial harvest in the Michigan waters of Lake Erie in 2007 consisted of 13 species of fish, weighing a total of 1,058,253 pounds, with an estimated value of
$398,253. Total catch was dominated by three types of fish accounting for about 66% of the total harvest by weight: the common carp (23%), gizzard shad (23%), and buffalo (13%). Other species harvested included channel catfish (9%), white bass (7%), freshwater drum (6%), goldfish (4%), white perch (3%), whitefish (1%),
and others (3%), including bullheads, suckers, quillback and chub (Thomas, 2008).
Recreational Species Lake Erie is the warmest and most biologically productive of the Great Lakes, producing more fish each year for human consumption than the other four Great Lakes combined. The Western Basin of Lake Erie is known as the "Walleye Capital of the World," producing more walleye per acre than any other lake globally. Important recreational species include both native and non-native species such as the common carp and the white perch, as well as the rainbow trout and brown trout.

Sport fishing harvest (non-charter) in the Michigan waters of Lake Erie in 2007 included approximately 369,624 fish, a number dominated by yellow perch (47%) and walleye (41%). Other species harvested by sport-fishermen included white perch (5%), channel catfish (4%), white bass (2%) and others (1%) including freshwater drum, largemouth bass, smallmouth bass, and rainbow trout. Trends in angler effort and harvest rates for walleye and yellow perch since the mid 1980s suggest that the level of angler effort is influenced by many factors in addition to harvest rates. Factors such as weather, prey fish abundance, fishing sources on other Great Lakes waters and regional economic conditions have likely contributed to the relatively low level of fishing effort since 1991.
Charter fishing harvest in the Michigan waters of Lake Erie in 2007 consisted of approximately 29,818 fish, dominated by walleye (66%) and yellow perch (33%). Together, walleye and yellow perch accounted for 99% of the charter fishing harvest. Other species harvested include the rainbow trout (Thomas, 2008).
3.0      Modifications to Survey Methodologies The data were evaluated to determine monthly and seasonal shifts in abundance and diversity. Based on the data presented in the interim report, it was agreed upon by DECo and the NRC during February 2009 audit meetings, that several aspects of the sampling program be modified. Included in these modifications were changes to the impingement and entrainment sampling program and the fish and the macroinvertebrate sampling program.
3.1      Impingement and Entrainment The entrainment sampling program was modified to demonstrate a more complete profile of organisms, by depth, and during peak recruitment season at the Fermi 2 intake. The following modifications were made:
Change in Entrainment Sample Depth(s)
In response to comments from NRC at the February 2009 audit meetings, entrainment sampling was modified to represent sample collections from near-bottom and near-surface depths. Subsequent samples were collected using a two pump system. One pump was set up to collect samples from near-bottom (at least one meter from bottom) and the other pump was positioned to collect samples from near-surface (at least one meter from surface). Each sample was collected simultaneously and combined into one composite sample for each six hour interval over the 24-hour sample period. Sampling, identification and enumeration procedures were otherwise unaltered. These changes applied to samples collected in April, May, June and July 2009.
Addition of entrainment samples One additional entrainment sample was collected in March 2009 to document the presence or absence of lake whitefish in the intake area. The addition of this sample was based on historic entrainment data collected at the Fermi 2 intake structure that found an increase in lake whitefish entrainment during the month of March. Four additional entrainment samples were scheduled, one each month during peak recruitment season, April 2009 through July 2009.
Modification of one Impingement Sample Due to operational constraints at the GSWPH, modifications to impingement samples were made during the September sample event. This sample was collected on a single 24 hour interval rather than the two 12 hour intervals used during the other sampling months. The screens were washed only once, for 30 minutes, at the end of the 24 hour sample period and the resulting collection represents the 24 hour sample period.

3.2       Fish and Macroinvertebrate Communities The fish and macroinvertebrate community characterization studies were modified based on preliminary findings presented in the interim report which led to the reduction of sampling locations from nine locations to five.
The following locations remained as part of the aquatic sampling program from April 2009 through June 2009:
* North Canal (CN-A);
* Swan Creek (SC-A);
* Lake Erie - Intake (LE1-A);
* Lake Erie - South Lagoon (LE2-A); and
* South Canal (CS-A).
The following locations were removed from the aquatic sampling program and no samples were collected from April 2009 through June 2009 because these locations were isolated waterbodies and the populations were not expected to undergo dramatic fluctuations:
* South Quarry (SQ-A);
* North Quarry (NQ-A);
* Isolated Pond (IP-A); and
* Isolated Central Canal (IC-A).
4.0       Results The following section provides the results for each of the different sampling programs completed at the Fermi site including an evaluation of species abundance, richness and composition for each of the programs, as well as impingement and entrainment rates 4.1       Impingement and Entrainment Impingement A total of 11 impingement samples were collected during the period from August 2008 through July 2009. Table 7 provides a summary of fish species collected in the impingement samples at the Fermi 2 GSWPH. A total of 101 fish were collected during the 11 impingement samples. The December 2008 sample yielded the greatest number of fish (34) while the June 2009 and July 2009 samples yielded the fewest fish (1). Fish composition was dominated by gizzard shad (39%), emerald shiner (29%), white perch (10%) and bluegill (7%), Figure 3. A total of 15 species of fish were represented in the samples ranging from seven in September 2008 to one in both June 2009 and July 2009. Impinged organisms ranged from 24mm to 368 mm total length. The smallest individual organism impinged was the spottail shiner with the largest being the freshwater drum. No federally or state listed threatened or endangered species were collected.

The average annual impingement rate for all species collected in the 11 samples from August 2008 through July 2009 was 3                                                                                            3 4.6E-5/m . Of the 15 species identified, the gizzard shad had the highest impingement rate (1.8E-5/m ) There 3
were eight species which shared the lowest impingement rate (4.5E-7/m ). Table 8 provides a summary of impingement rates at the Fermi Site from August 2008 through July 2009.
Table 9 provides an estimate of impingement abundance by species and month for the Fermi 2 facility with cooling water intake pumps at operational capacity (provided by DECo for each sample month). Of the estimated 3,102 fish impinged annually at operational capacity, December (1,054) and March (806) reflect the greatest estimated impingement while June (30) and July (31) reflect the lowest estimates. The estimated annual impingement ranges from 1204 for the gizzard shad to 30 for several species, including the bluntnose minnow, channel catfish, freshwater drum, green sunfish and rock bass.
Based upon Fermi 3 operations at maximum capacity (32,264 gpm) , it is estimated that 3,110 fish will be impinged annually. Of these, December represents the greatest estimate (1,090) while June represents the lowest estimate (24). The estimated annual impingement at maximum capacity for each species ranges from 1,246 for the gizzard shad to 24 for the bluntnose minnow, channel catfish, freshwater drum, green sunfish and rock bass, Table 10.
Entrainment Thirteen entrainment samples were collected during 10 months from July 2008 through July 2009. Table 11 provides a summary of fish larvae and eggs collected in entrainment samples at the Fermi GSWPH. A total of 1286 fish (81 eggs and 1205 larvae) were entrained, consisting of 12 identified taxa, 74 unidentified eggs and 2 3
unidentified centrarchid larvae. A total of 1,306.79 m of water was collected and filtered throughout the study.
The May 2009 sample yielded the greatest number of fish (533), while both November 2008 and March 2009 yielded the lowest number (0). Sample composition was dominated by gizzard shad (37%), emerald shiner (18%), bluntnose minnow (14%) and yellow perch (13%), Figure 4.
3                         3                       3 Entrainment rates (fish eggs + larvae/m ) ranged from 4.82/m in July 2009 to 0.00/m in November 2008 and March 2009. The average annual entrainment rate for all species collected from July 2008 through July 2009 3
was 0.98/m . Of the 12 taxa identified in entrainment samples, the gizzard shad reflected the highest 3
entrainment rate at 0.36/m while the white perch and the brook silverside had the lowest entrainment rates at 3
0.0015/m . Table 12 provides a summary of entrainment rates at the Fermi 2 GSWPH from July 2008 through July 2009.
Table 13 provides an estimate of entrainment abundance by species and month for the Fermi 2 facility with cooling water intake pumps at operational capacity (Provided by DECo for each sample month). Of the 62,566,648 fish (3,940,823 eggs and 58,625,825 larvae) estimated to be entrained annually, July reflects the highest estimated entrainment (33,852,880), while both November and March have an estimated entrainment of zero fish with pumps at operational capacity. The estimated annual entrainment ranges from 30,238,133 for the gizzard shad to 59,297 for the brook silverside.
With the Fermi 3 cooling water intake pumps operating at maximum capacity (32,264 gpm), it is estimated that 54,776,573 fish (3,450,157 eggs and 51,326,416 larvae) will be entrained annually, with the largest number of fish being entrained in July (27,896,935 fish) and that zero fish will be entrained in November and March.
Gizzard shad is expected to reflect the greatest level of annual entrainment with 47,628,660, while unknown Centrarchid are expected to be entrained the least with 106,033 fish entrained annually. For a review of 2                                                                                        -4 Impingement rates are expressed in scientific notation; 1.9E-4 is equivalent to 1.9x10 8

Commercial Species In 2007, the Lake Erie commercial fishery was dominated by the harvest of common carp, gizzard shad and buffalo, followed by channel catfish, white bass, freshwater drum, goldfish, white perch and whitefish. The aquatic sampling in the western basin of Lake Erie, adjacent to the Fermi site, and in onsite aquatic habitats confirmed the presence of each of the above listed species, aside from the whitefish.
Sampling of the fish community at nine locations from July 2008 through July 2009, in both onsite aquatic habitats and in Lake Erie found goldfish (21%), gizzard shad (18%), common carp (5%), white perch (5%) and bigmouth buffalo (2%) to be the most prominent commercial species. Samples also contained very small numbers of channel catfish, white bass and freshwater drum, each representing less than 1% of all fish community samples collected at the Fermi site.
Commercial species present in impingement samples include gizzard shad (39%) and white perch (10%).
Freshwater drum and channel catfish were also present in impingement samples at very low rates, representing less than 1% of all impingement samples. Entrainment samples noted the presence of gizzard shad (37%), bigmouth buffalo (4%) and freshwater drum (3%) larvae and/or eggs. White perch and channel catfish larvae and/or eggs were also present in entrainment samples at very low rates, each representing less than 1% of all entrainment samples collected at the Fermi site.
Recreational Species The Lake Erie recreational fish harvest was dominated by yellow perch and walleye, 88% combined, with a much smaller recreational harvest of white perch, channel catfish, white bass, freshwater drum, largemouth bass, smallmouth bass and rainbow trout. The aquatic sampling program confirmed the presence of each of the above listed species, with the exception of walleye, in the western basin of Lake Erie, adjacent to the Fermi site, and/or in other onsite aquatic habitats.
Results from fish community sampling in nine aquatic habitat locations found white perch (5%), largemouth bass (3%) and yellow perch (1%) to be the most prominent recreational species. The collections also noted the presence of channel catfish, white bass, freshwater drum, smallmouth bass and rainbow trout, each representing less than 1% of all fish community samples collected at the Fermi site.
Recreational species present in impingement samples include white perch (10%) and smallmouth bass (2%).
Channel catfish, freshwater drum and largemouth bass were also present in impingement samples at a very low rate, representing less than 1% of all impingement samples. Entrainment samples noted the presence of yellow perch (13%) and freshwater drum (3%) larvae. No eggs that could be identified were collected for these two species. White perch, channel catfish and largemouth bass were also noted in entrainment samples at a very low rate, each representing less than 1% of all entrainment samples.
5.0       Discussion and Conclusions The purpose of this study was to collect data over a one year period to supplement the aquatic data included in the Environmental Report of the COLA. The goals of the study were to determine fish species currently impacted by impingement and entrainment as part of the GSWPH for Fermi 2, compare current and historical impingement and entrainment data to determine the potential for impingement and entrainment for the proposed Fermi 3 Power Plant, determine species richness and relative abundance for fish and macroinvertebrates on-site and adjacent to the site in Lake Erie and Swan Creek, and identify potential impacts to aquatic resources associated with the proposed expansion project. The following discussion section evaluates the results of this study with regard to the aforementioned objectives.

Impingement and Entrainment A total of 101 fish were collected during the impingement study. Based on actual number of fish collected, impacts due to travelling screen operations appear minimal. Overall impingement numbers were low each month with peaks occurring in December and March and lows occurring in June and July during the summer months. The peak in November was associated with the presence of gizzard and the peak in March was associated with emerald shiner. Increased abundances of gizzard shad were expected due to the rapidly declining seasonal Lake Erie water temperatures. Increased abundance of emerald shiner in March is associated with spring movement in the western basin of Lake Erie.
These numbers indicate a low to moderate relative species richness and abundance across all samples collected at the Fermi 2 intake. This notion is confirmed through examination of the fish community at the two Lake Erie sample locations. The Lake Erie - South Lagoon site exhibited relatively high levels of species richness and abundance (a total of 3,856 fish from 38 species collected in seven monthly samples). These relatively high levels can be attributed to the abundant aquatic habitat and vegetation found in the South Lagoon. North of the South Lagoon, at the Lake Erie - Intake location, species richness and diversity (a total of 1,909 fish collected from 19 species) were almost exactly half of those found in the South Lagoon. This can be attributed to the decline in sufficient quality aquatic habitat along the shoreline north of the South Lagoon. The abundant vegetation and riparian buffer give way to the open waters of Lake Erie where fish are exposed to increased turbidity, winds and waves. Even further north, the impingement sampling took place at the Fermi 2 GSWPH. Similar to the Lake Erie - Intake location, impingement samples found relatively low species richness and abundance. This is likely due to the open water nature of the aquatic habitat in the vicinity of the intake structure.
A total of only 1,286 fish (81 eggs +1205 larvae) were collected in entrainment samples during this study which indicates that impacts to fish eggs and larvae are low. The greatest numbers of fish were collected during May and July with zero fish collected in the November and December samples. Sampling yielded relatively low levels of species richness with generally higher numbers in the spring time as compared to those found in the fall. Contributing factors include the fact that the spring season is peak recruitment season in Lake Erie.
Accordingly, a second sample was collected during the months of April, May and June at multiple depths to ensure an adequate depth profile. In addition to the increased spring entrainment, there were zero fish entrained in both November and March (the months immediately before and after icing). Fish collected in entrainment samples were dominated by gizzard shad, emerald shiner, bluntnose minnow, and yellow perch.
These results were expected due to the densities observed in the current fish community assessment and historical studies.
Fish & Macroinvertebrate Communities The quantity and variety of fish species collected during this aquatic survey indicate that each of the nine aquatic communities sampled supports a diverse assemblage of fauna. Sample locations such as Swan Creek, Lake Erie-Intake Area, Lake Erie-South Lagoon, the North Canal and South Canal all have relatively high numbers of fish and species richness, which is representative of a sufficiently structured (healthy) ecosystem.
All of these aquatic resources are hydrologically connected which allows for movement of fish species to and from each of these areas. Fish composition within these areas is highly diverse with no one species dominating all five locations. Gizzard shad was most prevalent at one Lake Erie site (and was second most prevalent at the other Lake Erie site) and the Swan Creek station, moderately abundant in the North and Isolated Central Canals, and was less prevalent in the South Canal and both Quarry sites. This is consistent with their habitat requirements which suggest that they are more common in open water. Other species common to all five locations included goldfish, bluegills and other sunfish species, as well as shiner species. This would be expected based upon the life histories and habitat requirements of species collected, which is indicative of a sufficiently structured (healthy) fish community with available resources. White perch were also collected at the Lake Erie, Swan Creek and North and South Canal stations.

Comparisons between the three sample stations associated with the internal canal system indicate that the fish species composition was similar between the Isolated Central Canal and North Canal sites and that both of these aquatic systems had a somewhat different composition than observed in the South Canal. For example, the North and Isolated Central Canals were generally dominated by bluegill, gizzard shad and other centrarchid species and the South Canal was dominated by goldfish, common carp and other centrarchid species. This observation is likely attributed to the isolation of the three systems.
The Isolated Central Canal, North Quarry and South Quarry had relatively high numbers of fish but a low to moderate species richness. These lower values may be attributed to the isolated nature of each system. All three systems consist of aquatic habitat such as fringing wetland vegetation and required forage organisms necessary for supporting fish populations; however, they are completely cut off from the adjacent aquatic resources that support more diverse fish assemblages. The Isolated Pond had the fewest number of fish as well as the lowest species richness. This is evident given the isolated location of the pond and the shallow water habitat that would tend to restrict the level of fish reproduction.
The two Lake Erie sample locations had comparatively different species richness and abundance. The Lake Erie-Intake location had much lower species richness and abundance levels. Even though the sampling methodologies were different, differences between the two locations are more likely attributed to differences in habitat structure associated with each location. The Intake location is located along a sand to gravel beach in the open waters of Lake Erie with little to no structure or habitat present for cover or spawning. The South Lagoon location has both sand and gravel shoreline as well as vegetated shoreline to support structure for cover and spawning. In addition, the South Lagoon location is at the confluence of the South Lagoon which has extensive aquatic vegetation that potentially supports a larger fish population, those of which can move freely from the lagoon out into the main body of the lake.
Collected macroinvertebrate samples indicate that all nine locations support a sufficiently structured benthic community typical of those expected in the aquatic habitats observed at the Fermi site. Nearly every site exhibited relatively high proportion of midges, oligochaete worms and/or amphipods. The samples associated with Swan Creek showed the greatest family diversity and were dominated by oligochaete worms while samples associated with Lake Erie were moderately to highly diverse and were dominated by amphipods, midges and mayflies. The North and South Canals included high macroinvertebrate family diversity and were dominated by oligochaetes and mayflies. The Central Canal exhibited less diversity in macroinvertbrate community structure as compared to the other two canal sites and was dominated by amphipods and oligochaetes. The Isolated Pond had moderate diversity and was dominated by multiple species of oligochaetes and midges. Benthic samples associated with the quarry lakes were the least diverse and were generally dominated by midge and mayfly families which could be explained by suitable substrates.
During the study, an inquiry arose concerning the presence or absence of the bloody-red shrimp (Hemimysis anomala) at the Fermi 2 site. In response, an examination of the data collected in this study indicated that no bloody-red shrimp were collected at the Fermi 2 site.
Historical Impingement and Entrainment Impingement sampling at the Fermi 2 GSWPH in 1991 and 1992 found a total of 23 species impinged whereas the current data indicated only 15 species during a similar, one-year study. Of the 23 species identified in impingement samples from 1991 to 1992, gizzard shad (71%), white perch (7%) rock bass (3%) and freshwater drum (3%) were the most abundant species collected (Lawler et al 1993).. The current study also indicated high compositions of gizzard shad (39%) and white perch (10%). However, the current study had a much higher compostion of emerald shiner than the 1991-1992 study (29% vs. 3%). Also, the current study collected the round goby, an invasive species, that had not been collected during the earlier study. The 1991-1992 study found the greatest levels of impingement during the fall and winter months with the lowest levels during the summer months. The current study also noted highest impingement levels during December and March and lowest impingement numbers during June and July. Both studies generally indicated higher species richness during the winter months than the summer months. Similar to the current study, impingement sampling 16

conducted at the Fermi 1 site from 1974 to 1975 also found that gizzard shad (46%), emerald shiner (35%),
and yellow perch (5.6%) were the most abundant species collected (Detroit Edison 1976). Probable explanations for the increased abundance of this species include the slower swimming speeds of these fish related to colder temperatures, therefore the ability to escape impingement is reduced in these species during the winter months. A noticeable difference between the two historical studies conducted at the Fermi site is the relatively low number of emerald shiner collected in the 1991-1992 study while it was a dominant species not only in the 1974-1975 study, but the current study as well. It should be noted that comparisons with the Fermi 1 impingement results are somewhat problematic due to the limited data collections as a result of the intermittent operation of this peaking facility during the 1970s. This unit no longer operates.
Similar historical studies from neighboring power plants in the western basin of Lake Erie were evaluated for comparison and support the current findings. Similar to the current study, impingement studies conducted at the nearby Monroe plant from 2005 to 2006 (Golder, 2008) and the Bay Shore plant from 1976-1977 (Reutter, 1978) indicated impingement samples dominated by gizzard shad, 96% and 64% respectively. Sampling at the Davis Besse plant in 1978 (Reutter, 1979) noted samples dominated by goldfish (50%), yellow perch (24%)
emerald shiner (15%) and gizzard shad (6.0%). The most noteworthy difference between the Davis Besse results and the results of the current study is the percent composition of goldfish in the historical study (50%) as no goldfish were impinged in the current study.
Entrainment sampling conducted at the Fermi 2 GSWPH from 1991-1992 noted a total of 28 taxa compared to the current study which indicated half as many during a similar one year entrainment study. Of the 28 taxa identified in entrainment sampling from 1991 to 1992, clupeids (34%), consisting of gizzard shad, alewife, and Morone sp (23%), consisting of white bass and white perch, dominated larvae and egg collections (Lawler et al 1993). The current study indicates a comparable composition of gizzard shad larvae and eggs, but noted very few white perch larvae. In addition, the current study indicates elevated numbers of emerald shiner, bluntnose minnow, and yellow perch, while for the 1991-1992 study cyprinids comprised 21% of the collections. The entrainment data collected in 1991 and 1992 also note the presence of lake whitefish (2% of total entrainment) during late March and April 1992. No lake whitefish were collected in the current study. The absence of whitefish in the current study is likely attributed to the lack of suitable spawning habitat within the vicinity of the Fermi site. Similar to the current study and the 1991-1992 study, an entrainment study conducted at the Fermi site from 1974-1975 found samples dominated by the family Clupeidae (53%), comprised of gizzard shad and alewife. The 1974-1975 study also collected relatively high numbers of yellow perch and freshwater drum (Detroit Edison 1976). However, as mentioned earlier, sampling was very limited in 1974-1975.
In addition to the historical entrainment studies conducted at the Fermi site, studies from other power plants on Lake Erie in the vicinity of the Fermi site were compared to the current study for reference. These findings indicate results similar to those of the current study. Gizzard shad was the most common species collected in three entrainment studies and was the second most common in the fourth. It comprised 57% in a study conducted at the Acme power plant from 1976-1977 (Reutter, 1978), 78% at the Bay Shore plant from 1976-1977 (Reutter, 1978), 52% at the Davis Besse plant in 1978 (Reutter, 1979), and 17% of eggs and 27% of larvae at the Monroe plant from 2005 to 2006 (Golder, 2008). Similar to the current study at the Fermi 2 plant, the freshwater drum and emerald shiner were common throughout the historical entrainment data.
For the purpose of discussing potential impacts associated with the Fermi 3 plant, current impingement and 3
entrainment rates (#/m ) from the Fermi 2 site were used to estimate potential impingement and entrainment abundance. The calculations were performed in two manners: first, using the Fermi 2 operational volume from 2008 through 2009; and second, using the maximum flow volume at the proposed Fermi 3 Power Plant. The use of the two flow volumes allowed for the development of a series of estimated abundances ranging from the likely impingement and entrainment at the Fermi 2 when at operational capacity to the worst case scenario impingement and entrainment at the proposed Fermi 3 Power Plant with intake pumps functioning at maximum capacity. While these numbers may be useful in estimating potential impacts at the Fermi site, they are not adequate for comparison with historical studies. For example, the 1991-1992 study concluded that an estimated 2,955,693 fish (72,367 eggs and 2,883,326 larvae) would be entrained annually whereas the current study concluded that approximately 62,566,648 fish (3,940,823 eggs and 58,625,825 larvae) would be 17

entrained annually at operational capacity. This is partially explained by differences in estimated annual intake 3
volumes. The historical sample reported operational intake flow at Fermi 2 to be approximately 58,000,000 m (Lawler, 1993) annually while the current study found the annual operational flow volume at Fermi 2 to be 3
approximately 70,000,000 m . In addition to discrepancies in estimated flow volume, reaching a definitive conclusion based upon any one year study (historic or current) should be done cautiously because any one data point in a one year study could skew the results and interpretations (e.g. - high/low entrainment during any one collection event as exampled by the high gizzard shad influx in July 2009).
Potential Impacts Associated with Proposed Fermi 3 Expansion The current site plan for Fermi 3 indicates that three of the identified on-site waterbodies will be directly impacted. The north canal and isolated central canal will be completely filled in along with a portion of the south canal. Permanent impacts in the north canal and isolated central canal will result in the loss of all aquatic organisms and their habitats, while impacts in the south canal will result in minimal losses.
Indirect impacts associated with construction of Fermi 3 will be related to surface water runoff, sedimentation of habitats, increased turbidity, and erosion. These impacts may temporarily interfere with, but should not inhibit, the normal life processes of many of the organisms identified by this study. Most of these organisms are considered tolerant species that are common to areas where natural disturbances occur and are able to adapt to temporary fluctuations in the environment. Based on the proposed construction locations at the Fermi site it is anticipated that the overall impacts from the construction activities will result in minimal indirect impacts to aquatic communities. The Fermi site has numerous wetland areas between many of the on-site waterbodies that will provide a natural buffer and vegetative structure to reduce erosion. More importantly, DECo will implement a Soil Erosion Sediment Control Plan (SESC) and will operate under a National Pollution Discharge Elimination System Permit (NPDES). During construction, DECo will implement Best Management Practices (BMP) that may include the use of hay bales and silt fences near potentially affected waterbodies.
Potential impingement and entrainment impacts at the Fermi 3 site were addressed by utilizing rates from the Fermi 2 plant in conjunction with monthly operational and maximum flow capacity data to estimate monthly and annual impingement and entrainment. For the purpose of these calculations and characterization, operational capacity is defined as the monthly volume of water withdrawn by the Fermi 2 plant, as reported by DECo, and maximum capacity is defined as the maximum potential volume of water withdrawn by the proposed Fermi 3 Power Plant with intake pumps operating at maximum capacity (34,265 gpm).
It is estimated that 3,102 fish are impinged annually at the Fermi 2 site with the pumps at operational capacity.
Of these, December (1,054) and March (806) reflect the greatest estimated impingement while June (30) and July (31) reflect the lowest estimates. The estimated impingement at operational capacity for each species, annually, ranges from 1,204 for the gizzard shad to 30 for several species, including the bluntnose minnow, channel catfish, freshwater drum, green sunfish and rock bass. With the Fermi 3 cooling water intake pumps operating at maximum capacity, it is estimated that 3,110 fish will be impinged annually. Of these, December represents the greatest estimate (1,090) while June represents the lowest estimate (24). The estimated annual impingement at maximum capacity for each species ranges from 1,246 for the gizzard shad to 24 for the bluntnose minnow, channel catfish, freshwater drum, green sunfish and rock bass.
With the Fermi 2 cooling water intake pumps at operational capacity, 62,566,648 fish (3,940,823 eggs and 58,625,825 larvae) are estimated to be entrained annually. July 2009 reflects the greatest estimate of entrainment abundance (33,852,880), while both November and March represent an estimated entrainment abundance of zero. The estimated annual entrainment ranges from 30,238,133 for gizzard shad to 59,297 for brook silverside. It is estimated that of the 54,776,573 fish (3,450,157 eggs and 51,326,416 larvae) entrained annually with Fermi 3 pumps operating at maximum capacity, the largest number of fish will be entrained in July (27,776,573) and that zero fish will be entrained in November and March. Estimates for Fermi 3 with pumps operating at maximum capacity indicate that the gizzard shad is expected to reflect the greatest level of annual entrainment with 25,106,899, while brook silverside are expected to be entrained the least with 57,861. While no entrainment data were collected December through February due to icing on Lake Erie, it is assumed that if 18

any entrainment occurred it would be minimal because no eggs or larvae should exist during this time of year.
The 1991-1192 study did not collect any eggs or larvae during this time period. Therefore, the exclusion of monthly estimates for those months is expected to have a negligible impact on annual estimates. This conclusion is reinforced with the fact that no organisms were collected in either the November or the March sample, on either side of the winter months in which no entrainment sampling was conducted.
The estimates based upon operational flow capacity are considered to be the most representative of the Fermi 2 Power Plants potential impacts by impingement and entrainment. The maximum capacity estimates are only provided as a worst case scenario and should not be interpreted as representative of impacts under normal plant operation.
Historical data associated with the on-site waterbodies or with similar waterbodies within the general area of the Fermi 2 Power Plant are either nonexistent, very limited in scope and detail, or possibly outdated. Data presented in this study provide a baseline assessment that supports the characterization of fish and benthic communities in the on-site waterbodies and evaluates the species diversity and abundances of fish and ichthyoplankton impacted due to impingement and entrainment. These data are designed to supplement the information provided in the Environmental Report of the COLA application.

Appendix B Life Histories for Threatened and Endangered Species The following species are listed as threatened or endangered in Monroe County, Michigan either by the federal government (USFWS) or by the State of Michigan (MDNR). These life histories provide available information on abundance, and any critical life-support requirements such as spawning areas, nursery grounds, food habits, and feeding areas. Supplemental life history data was gathered from NatureServe wildlife database.
Fish Lake sturgeon-Acipenser fulvescens The lake sturgeon is listed as a threatened species in Michigan, and is endangered in Ohio. Historically, it has been found in the Hudson Bay watershed, the St. Lawrence estuary, the upper and middle Mississippi River and Great Lakes basins, and scattered throughout the Tennessee, Ohio, and lower Mississippi drainages. It has become rare throughout its historic range, and population estimates are around one percent of their original numbers. Michigan populations are some of the largest, and are scattered throughout most counties bordering the Great Lakes, as well as some inland lakes and rivers.
The lake sturgeon is a benthic organism that occurs in large rivers and the shallow areas of large lakes where food is abundant. They tend to avoid aquatic vegetation and prefer deep run and pool habitats of rivers. Their habitat use varies in lakes, depending on what conditions are available.
Lake sturgeon begin spawning migrations in May when the water temperature reaches 10-12 degrees Celsius, but do not actually begin spawning until the water is between 13 and 18 degrees Celsius. Spawning habitat is defined by swift currents, clean rocky substrates, and depths of two to fifteen feet. Large females spawn only once every 3-7 years, but will lay hundreds of thousands of black, adhesive eggs. The eggs are instantly fertilized by a male, who may spawn every one or two years. The eggs hatch in five days, and the juveniles grow relatively quickly for ten years, but growth slows considerably thereafter. Males reach sexual maturity at about 15 years of age, while females do at about 25 years of age. The lake sturgeon has the greatest life expectancy of any freshwater fish, with some individuals reaching 80 years of age. The most recently documented spawning area along Michigans Lake Erie shoreline is near Stony Point in Monroe County, however activity has diminished recently and may have ceased.
The lake sturgeon is a bottom feeder that uses its protrusible mouth to extract prey as it forages over gravel, sand, and/or mud substrates. Prey for this sturgeon includes snails, clams, crustaceans, fish, and aquatic insect larvae. The sturgeon will also prey upon eggs of other species of fish during foraging.
Lake Erie was formerly one of the most productive waters for lake sturgeon in North America. The lake sturgeon population in Michigan is estimated to be approximately 1% of its former abundance. In the 1800s, sturgeon were perceived as a pest and a nuisance because they often caused damage to fishing gear in nearshore waters. In the 1860s, the lake sturgeon population was greatly reduced in Lake Erie as a bycatch of the booming gill net fishery. In the following years, over-harvesting, limited reproduction and destruction of spawning habitats nearly eradicated the sturgeon population in the lake.
Lake sturgeon can be utilized as an indicator of ecosystem health because they are very sensitive to human disturbances such as habitat decline and pollution as illustrated by their sharp decline in the late 1800s and early 1900s. The most recently documented spawning area on the Lake Erie shoreline was near Stony Point in Monroe County, but activity has diminished and may have ceased altogether. They are not known to occur contemporarily in Swan and Stony Creeks (Goforth, 2000).

Eastern sand darter-Ammocrypta pellucida The eastern sand darter may be found from the St. Lawrence River drainage, the Lake Champlain drainage in Vermont, south to West Virginia and Kentucky, and west through Ontario and Michigan. Within Michigan, this darter was found historically in the Huron, Detroit, St. Joseph, Raisin, and Rouge Rivers, as well as Lake St.
Clair. However, in the last two decades it has only been recorded in the Lake St. Clair and Huron River drainages.
The preferred habitats of the eastern sand darter are streams and rivers with sandy substrates, and lakes with sandy shoals. They frequently occur in slow moving waters that deposit fine sand, often just downstream of a bend.
Spawning occurs from April through June when water temperatures are around 20-23 degrees Celsius. They deposit their eggs singly, and bury them in the sandy substrate. These darters reach sexual maturity at age one and have a life expectancy of only 2-3 years. The eastern sand darter spends a large amount of its time half-buried in the substrate, presumably to conserve energy and maintain its position on the bottom.
The eastern sand darter feeds mostly on chironomid larvae, but will also prey upon oligochaetes and cladocerans.
The eastern sand darter currently has no known populations in Monroe County (Derosier, 2004).
Creek chubsucker-Erimyzon oblongus The creek chubsucker has only been listed as endangered by the state of Michigan. This species occurs throughout most of the eastern United States, but is becoming increasingly rare toward the edges of its distribution. The creek chubsuckers northern range terminates in Michigan, where it has been found in the Kalamazoo, St. Joseph, and Raisin Rivers and their tributaries. For the last two decades it has only been reported in the Kalamazoo River, located west of Monroe County.
The creek chubsucker inhabits headwaters and clear creeks with moderate currents over sand-gravel substrate, sometimes near aquatic vegetation. This holds true in Michigan, where it has been reported in moderately swift streams up to five feet deep with sand, gravel and mud bottoms.
The creek chubsucker migrates upstream to spawn in early spring. Eggs are generally scattered over substrates, but males have been observed building nests. Adults may produce up to 9,000 eggs per year.
Juveniles of this species prefer to form schools in vegetated areas with less current, but migrate to deeper downstream areas as they become adults. Life expectancy of the creek chubsucker is approximately five years.
The diet of the creek chubsucker is mostly small invertebrates living on the substrate. However, the terminal mouth of the creek chubsucker suggests that it may feed less on the bottom than other species of suckers.
The habitat near the Fermi site is not an ideal habitat for the creek chubsucker. However, many populations remaining in Michigan have adapted to non-traditional habitats (Carman, 2007).
Silver shiner-Notropis photogenis The silver shiner is listed as endangered by the state of Michigan. This species ranges from the Great Lakes and their tributaries, through the Ohio River basin and Tennessee drainage, to northern Alabama and Georgia.
This shiner is fairly common within most of the Ohio River basin, but occurs more rarely in the Great Lakes tributaries. Within Michigan it is locally abundant in the St. Joseph and Raisin Rivers. Historically, the silver shiner had been identified in Monroe County and the Huron River.
B-2

Preferred habitat for the silver shiner is medium to large streams with moderate to high gradients. They are often found in the deeper water pools or eddies directly below riffles. This species has been documented to prefer a variety of substrates, including gravel and boulder, pebble and cobble, and sand, mud and clay.
Despite the disputes over substrate, it is agreed that silver shiners avoid areas with heavy vegetation and siltation. In Michigan, the shiner has been found to inhabit areas of strong current with wooded banks.
Reproduction of silver shiners is not well documented, due to the fact that spawning behavior has not been observed. Silver shiners are theorized to spawn around June, and may move into different habitats to do so.
The juvenile shiners exhibit rapid growth, reaching sexual maturity at age two, and maximum size by age three.
Although the silver shiner primarily feeds at the surface, it will take mid-water prey as well. The majority of the silver shiners prey are aquatic insects, with adult Diptera (true flies) representing the largest portion of gut samples. Silver shiners have even been documented as leaping into the air to capture low-flying insects.
The silver shiner is relatively rare in Michigan and is fairly tolerant to human impact. Populations appear to be stable (Carmen 2007). Previous impingement studies have not recorded this species, thus impingement is expected to be minimal.
Pugnose minnow-Opsopoeodus emiliae The pugnose minnow is listed by both Michigan and Ohio as endangered. The pugnose minnow has been documented from the southern Great Lakes basin, through the Mississippi River valley, to the Gulf of Mexico.
Although common in the southeastern portion of its range, it is becoming rare in the northern portion.
Historically, the pugnose minnow was documented in Michigan tributaries and nearshore areas of Lake Erie and Lake St. Clair, however the only record in the past twenty years was in the Detroit River near Grosse Isle, located approximately 15 mile northeast of the Fermi site.
The pugnose minnow inhabits the slow, clear waters of rivers and shallow regions of lakes. It is found in greatest abundance in weedy areas over sand or organic substrate. Historically, it has also been found in turbid areas of the Huron River that lacked submergent vegetation, most likely due to remnant populations changing habitats in submarginal conditions.
The life history of the pugnose minnow is not well documented. The male selects a spawning site where the female lays adhesive eggs, usually under a flat rock. Males then guard the nest, but will make excursions away, unlike bluntnose and fathead minnows. Species growth is rapid, reaching its adult size of two inches in length within two years.
The vertically-oriented mouth of the pugnose minnow suggests adaptation for feeding near the water surface.
Diet studies have shown the pugnose minnow feeds on microcrustaceans, fly larvae, and other aquatic invertebrates, as well as algae and plants (Carman, 2007).
The pugnose minnow is listed in Monroe County, MI, but has not been reported in previous impingement studies, or even recorded in the last two decades.
Channel darter-Percina copelandi The channel darter is listed as endangered by the state of Michigan. Its distribution extends from the upper St.
Lawrence drainages, through the Great Lakes basin, and into the Ohio River basin. The darter is found primarily in the Ohio River basin, but isolated populations occur southward to Louisiana. In Michigan, the darters range includes the nearshore areas of Lake Erie and Lake Huron. Since 1994, it has only been recorded in the Au Sable, Pine, and St. Clair Rivers in Michigan.
The channel darters habitat includes rivers and large creeks with moderate current over sand and gravel substrate. It has also been recorded in wave-swept areas of Lake Huron and Lake Erie with coarse-sand, fine-B-3

gravel beach and sandbar substrates. The darter is usually found in deeper water, but will move into shallow water (<1 m) at night.
Flowing water is essential to channel darter spawning, which has been observed in the Cheboygan River, located north-northwest of the Fermi site, in mid-July. Males maintain a 1-meter nest station around a large rock, where the female buries herself partially to deposit her eggs. After the male fertilizes them, both parents depart the nest of adhesive eggs and provide no parental care.
Channel darters are benthic feeders whose diet is comprised of small invertebrates including mayfly and midge larvae, small crustaceans, algae, and organic debris.
The channel darter has not been recorded in Monroe County in some time, most likely due to unsuitable habitat conditions (Carman, 2007).
River darter-Percina shumardi The river darter is listed as endangered by the state of Michigan. Its distribution ranges from southern Canada to the Gulf of Mexico. Historically, the river darter was found in rivers and nearshore areas of eastern Michigan, however the last report of the darter was in the Huron River in 1941, and the most recent surveys have found no records of river darters.
The river darter is found in rivers and large streams with deep, fast-flowing riffles and cobble and boulder bottoms. During nocturnal hours or when turbidity is high, the adult darters may move to shallower areas. This turbidity tolerance might explain its continued presence in the Mississippi River and its tributaries. The river darter has also been found in nearshore areas of the Great Lakes with depths approximating five meters.
The river darter tends to move upstream to spawn, toward the northern end of its range. Spawning occurs in late winter to early spring in southern areas, from April through May in the Midwest, and as late as June or July in Canada. The female darters are egg-burying spawners, expelling eggs into the substrate while partially buried. Neither males nor females provide parental care to their young. Species grow to three inches, mostly within the first year of development, and attain sexual maturity at age one. River darters are thought to live two to four years, with males having a greater life expectancy than females.
River darters tend to feed during the day upon a variety of small aquatic invertebrates. As juveniles, they primarily feed upon small zooplankton. Adult darters prey upon midge and caddisfly larvae, as well as some snail species (Carman, 2007).
Southern redbelly dace-Phoxinus erythrogaster (Rafinesque)
The southern redbelly dace is listed as endangered by the state of Michigan. Its total distribution ranges from the Lake Erie and Lake Michigan drainages, through the Mississippi River basin south to Alabama, Arkansas, and Oklahoma. The northern limit of this species range is in southeastern Michigan, in the Huron and Raisin Rivers.
The southern redbelly dace generally occurs in the clear and cool permanent headwaters of river systems. It prefers clear, wooded streams intermixed with small pools. These streams are usually small, with moderate gradients and overhanging vegetation that provides ample shade. Preferred substrates include mud bottoms of pools and clean gravel of riffles.
Life history of this species has only been studied extensively in the southern portion of its range, where they spawn from April to June. Southern redbelly dace reach sexual maturity within one year at a length of about one and a half inches. The spawning fish migrate from pools to graveled riffles where they utilize nests already built by other cyprinids. Two males pressure the sides of the typically larger female who then broadcasts 700 to 1000 eggs that are immediately fertilized.

This species is generally herbivorous, feeding upon filamentous algae, diatoms, and drifting or benthic detritus.
Larger fish will also feed on chironomid and mayfly larvae, as well as small invertebrates (Stagliano, 2001).
Sauger-Sander canadensis The sauger is listed as a threatened species by the state of Michigan. Its native range includes the St.
Lawrence, Great Lakes, Hudson Bay, and Mississippi River basins, as well as the Tennessee River in Alabama and Louisiana. The sauger has also been introduced into the Atlantic, Gulf, and southern Mississippi River drainages. This species was historically abundant in Lake Erie; however, it has only been recorded in the St.
Clair River and Lake St. Clair in the past two decades.
Sauger prefer turbid areas of lakes, reservoirs, and large rivers, where the temperatures throughout the entire water column are within their preferences.
This species spawns over gravel and rubble shoals in May or June, when temperatures range from 3.9 - 6.1 degrees Celsius. Rather than building nests, the sauger broadcasts demersal, adhesive eggs over the shoals during the night. After hatching, young sauger spend up to nine days absorbing yolk while on the bottom. Males reach sexual maturity within three years, while females take four to six years. The life expectancy for the sauger is up to 13 years.
Saugers have a specialized structure in their eyes that makes them very sensitive to light. They prefer to feed at night in clearer waters or during the day in turbid areas. As juveniles, they tend to prey on zooplankton and aquatic insect larvae. Adults feed upon fish and invertebrates such as gizzard shad, emerald shiner, crappie, bass, freshwater drum, leeches, crayfish, and insects (Derosier, 2004).
Mollusks White catspaw-Epioblasma obliquata perobliqua The white catspaw mussel is state endangered and from museum specimens, it has been confirmed that it once inhabited rivers in southeastern Michigan and nearshore areas in Lake Erie. Currently, the only know viable population is in Fish Creek, Indiana. The white catspaw is a medium sized mussel, up to two inches long.
The exterior shell color is tan with many fine wavy green rays. Little is known of their required habitat because this species is so rare.
This mussel prefers coarse, stable substrates, such as gravel and pebble and is typically found buried in the substrate. The exact breeding season is unknown, although other species of this genus typically release glochidia. The lifespan is estimated to exceed 15 years of age. The survival of the white catspaw mussel is currently in severe jeopardy. Changes in river hydrology and morphology can harm this riffle-dwelling species, and dredging, channelization and damming projects should be avoided (Natureserve, 2008).
Northern riffleshell-Epioblasma torulosa rangiana The northern riffleshell is federally and state endangered. Currently, the northern riffelshell have only been found in the Black, St. Clair and Detroit Rivers. More specifically, it is found in the Detroit River in Wayne County, Michigan. The northern riffelshell is of moderate size with large adults reaching two inches. The shell is light green-yellow to olive green, with dark, narrow, closely-spaced rays. This mussel requires swiftly moving, well-oxygenated water. Riffle and run areas with fine to coarse gravel are the preferred habitats. It is believed that this species can reach 15 years of age. The northern riffelshell is graved from late summer to the following spring, at which time the glochidia are released. The Detroit River may still have a viable reproducing population despite human impacts and zebra mussel infestation in the river. In 1992, 110 mussels were transplanted from the Detroit River to the St. Clair River. The survival of this species depends on the protection B-5

and preservation of habitat and host fish. Siltation and run-off must be reduced to facilitate the recovery of this species (Natureserve, 2008).
Snuffbox-Epioblasma triquetra The snuffbox mussel is state endangered and can be found in Otter Creek in Monroe County and the Detroit River in Wayne County. The snuffbox is about 2 inches in length and their shells are triangular and thick, yellowish on the outside, and covered with numerous, broken, dark green rays. It inhabits small and medium-sized rivers. They prefer habitats that contain sand, gravel, or cobble substrate with a swift current and individuals are often found buried deep in the sediment. Reproduction occurs in early to mid-August and the snuffbox lives between 8-10 years. The only host for the snuffbox glochidia is the log perch. This species is sensitive to river impoundment, siltation and disturbance, due to its requirement for clean, swift current and relative immobility as an adult (Natureserve, 2008).
Wavy-rayed lampmussel-Lampsilis fasciola The wavy-rayed lampmussel is state threatened and is sporadically distributed in the Great Lake tributaries of Lake Michigan, Lake Erie, Lake Huron, and Lake St. Clair. This mussel has a rounded to ovate, moderately thick shell and is usually under 3.5 inches in length. The shell color ranges from yellow to yellowish green with numerous thin wavy green rays.
It occurs in small to medium sized shallow streams, in and near riffles, with good currents. The wavy-rayed lampmussel prefers sand and/or gravel substrate. Males and females are dimorphic.
The release of the larvae (glochidia) coincides with host fish appearing in the shallow riffles. As adults, they remain relatively sessile, probably not moving more than 100 meters in a lifetime. This mussel, like most mussels, is sensitive to river impoundment, siltation and channel disturbance. The wavy-rayed lampmussel is often the first to be affected by disturbances because this species prefers areas with moderate flow and high oxygen content. Pollution is also a great threat to this species well being (Natureserve, 2008).
Round hickorynut-Obovaria subrotunda The round hickorynut is state endangered and can be found in the St Lawrence and Lake Erie/Lake St. Clair drainages, more specifically, in Lake St. Clair in Macomb County and in the Detroit River in Wayne County.
This mussel has a near perfectly circular shell that is moderately thick and inflated. The exterior of the shell is brown, smooth, and lacks rays.
The round hickorynut inhabits medium to large rivers and along the shores of Lake Erie and Lake St. Clair, near the river mouths and prefers sand and gravel substrate in areas with moderate flow. It is a long-term breeder, holding fertilized eggs over the winter. The life span is unknown. Like most mussels, this species is sensitive to river impoundment, siltation and channel disturbance as well as pollution (Natureserve, 2008).
Mudpuppy mussel (salamander mussel)-Simpsonaisa ambigua Historically, this species occurred throughout the upper Mississippi River drainage and as far south as the Cumberland River drainage of Tennessee. It is known from the Lake St. Clair, Lake Huron, and Lake Erie drainages; and from the Ohio River system, the Cumberland River system (Red River, Kentucky), and the upper Mississippi River system (Illinois, Iowa, Wisconsin, Missouri and Arkansas).
In Minnesota, it is present only in the lower St. Croix River where it is rare and localized. Its distribution in part is apparently related to the distribution of its glochidial host, the mudpuppy. In Canada, it is known from the Sydenham River and a potentially extant occurrence in the Thames River in London, Ontario.
B-6

The preferred habitat for this species is in sand or silt under large, flat stones in areas of a swift current. Its presence is presumably linked to the mudpuppy, Necturus maculosus. In Canada, the mudpuppy mussel is found in all types of clear, freshwater habitat, including creeks, streams, rivers and lakes; it is found on a variety of substrates (mud, silt, sand, gravel, cobble or boulder) in areas of swift current.
The host of this species is the mudpuppy. It is suspected "that necturus eats the adult mussel and in seeking food visits one rock after another. In satisfying its appetite it becomes infected with the mussel glochidia, nourishing them, and when they have matured serves as a transporting and distributing agent for the young mussels." Glochidia were found deeply imbedded in the external gills of the mudpuppy. There is some evidence that the glochidia are released in the fall (Natureserve, 2008).
Purple lilliput-Toxolasma lividus The purple lilliput is state endangered. Spent shells have been found from sites in the Raisin River in Monroe Country. It is a small mussel, growing to a little over an inch in length. The shell is smooth, but with growth lines and is light to dark green or brown. The purple lilliput occurs in small to medium sized streams, less often in large rivers and lakes.
This species preferred substrate is well-packed sand or gravel and occurs in water depth less that one meter. It is a long-term breeder, holding the larvae internally for about a year; however, their life span in unknown. The purple lilliput requires clean water for survival, therefore any practice that leads to siltation, pollution, or poor water quality should be avoided (Natureserve, 2008).
Mudpuppy mussel (salamander mussel)-Simpsonaisa ambigua Historically, this species occurred throughout the upper Mississippi River drainage and as far south as the Cumberland River drainage of Tennessee. It is known from the Lake St. Clair, Lake Huron, and Lake Erie drainages; and from the Ohio River system, the Cumberland River system (Red River, Kentucky), and the upper Mississippi River system (Illinois, Iowa, Wisconsin, Missouri and Arkansas).
In Minnesota, it is present only in the lower St. Croix River where it is rare and localized. Its distribution in part is apparently related to the distribution of its glochidial host, the mudpuppy.

Glochidia were found deeply imbedded in the external gills of the mudpuppy. There is some evidence that the glochidia are released in the fall (Naturserve, 2008).
Rayed bean-Villosa fabalis The rayed bean was historically known from 106 streams, lakes, and some man-made canals in 10 states and 3 Service regions. The mussel occurred in parts of the upper (i.e., Lake Michigan drainage), lower Great Lakes system, and throughout most of the Ohio and Tennessee River systems. Historically this species was known in Canada from the Thames, Sydenham, and Detroit Rivers and western Lake Erie in southwestern Ontario, but only still extant in the Sydenham and possibly the North Thames in Ontario where a live specimen was found in 2004. A new site was recently discovered in Swan Creek (Lower Maumee drainage) in Ohio.
B-7

The rayed bean is reported to be a long-term breeder in that it holds glochidia overwinter for spring release.
Gravid females have been collected during mid to late May. The glochidial fish hosts include the Tippecanoe darter.
The rayed bean is generally known from smaller headwater creeks, but records exist in larger rivers. They are usually found in or near shoal or riffle areas, and in the shallow wave-washed areas of glacial lakes, including Lake Erie. In Lake Erie, it is generally associated with islands in the western portion of the lake. Substrates typically include gravel and sand. It is oftentimes associated with vegetation (e.g., water willow, Justicia americana; water milfoil, Myriophyllum sp.) in and adjacent to riffles and shoals. Specimens are typically buried among the roots of the vegetation (Naturserve, 2008).
Purple wartyback-Cyclonaias tuberculata This species is state listed as special concern. The purple wartyback has a roughly circular outline with numerous bumps covering about 3/4 of the outside of the shell. The outer covering of the shell is yellow-brown or green-brown in young individuals, becoming dark brown in older individuals. The purple wartyback is found in medium to large rivers with gravel or mixed sand and gravel substrates in areas with relatively fast current.
Like most freshwater mussels of the family Unionidae, this species requires a fish host to complete its life cycle. The purple wartyback is a summer breeder and are likely to live over 25 years of age.
Threats to this species include habitat and water quality degradation from changes in water temperature and flow, the introduction of heavy metals, organic pollution such as excessive nutrients from fertilizers, pesticides and herbicides, dredging and increased sedimentation due to excessive erosion. Due to the unique life cycle of unionids, fish hosts must be present in order for reproduction to occur. The loss of habitat for these hosts can cause extirpation of unionid populations (Naturserve, 2008).
Slippershell mussel-Alasmidonta viridis This species is of state special concern. The slippershell mussel is a small mussel, usually around one and a half inches long. The exterior of the shell is yellowish-brown, marked with fine green rays. The slippershell is typically found in creeks and headwaters of rivers, but has also been reported in larger rivers and in lakes. The slippershell mussel requires a fish host to complete its life cycle. The slippershell is probably a long-term (bradytictic) breeder, holding the larvae internally for about a year. These larvae (glochidae) then are released into the water and mush attach to a suitable fish host in order to survive. After development, it drops from its host and spends the remainder of its life in the substrate. The lifespan is unknown. This mussel is a filter feeder.
The slippershell mussel requires clear, clean water and substrates for survival. Therefore, any practices that lead to increased siltation and poor water quality will decrease the quality of the habitat of the slippershell.
Also, since the slippershell cannot reproduce unless its fish host is present, conservation efforts should aim to maintain the composition of associated fish communities (Naturserve, 2008).

Life Histories for Commercially and Recreationally Important Species The following species are considered important species in aquatic ecosystems within the Michigan waters of Lake Erie because they are of commercial and/or recreational value. These life histories provide detailed information on any critical life-support requirements such as spawning areas, nursery grounds, food habits, feeding areas, wintering areas, and migration routes. Supplemental life history data was gathered from NatureServe wildlife database.
Fish Common Carp-Cyprinus carpio The common carp is distributed across every continent aside from Antarctica. In North America, this species can be found in each of the 48 contiguous states and throughout much of Canada. This member of the family Cyprinidae is extremely common throughout the Great Lakes region.
These fish are known to occur in rivers, lakes, ponds, reservoirs, swamps, and low-salinity estuaries; usually in shallow water with abundant vegetation and little or no current. The common carp generally does not inhabit first-order, cold streams or deep lakes with little or no littoral zone. Optimal river habitat for the carp is characterized by warm water (above 20 degrees C during the growing season, June through August), a low gradient, shallow-vegetated marshland available for spawning, pools and off-channel areas, adequate cover (brush, logs, etc.) and fertile conditions. Optimal lake habitat has warm water, aquatic/inundated vegetation for spawning, deeper waters for overwintering and fertile conditions.
Adult carps are omnivorous, relying largely on invertebrates, detritus, fish eggs and plant material as food sources. Fry feed mainly on zooplankton such as cladocerns and copepods but will consume phytoplankton if zooplankton densities are low.
Spawning occurs in spring and summer, usually in shallows and flooded areas with adequate aquatic or inundated vegetation.
Gizzard shad-Dorosoma cepedianum The gizzard shad is in the Family Clupeidae, the herring family. It is distributed through the mid to eastern region of the United States and the middle and south of Canada around the Great Lakes. As an adult, the gizzard shad will reach 9 to 14 inches in length and be up to two pounds. This fish can thrive in a wide variety of habitats including large rivers, reservoirs, lakes, swamps, bays, sloughs, and similar quiet open waters. Young and juveniles live in the more clear and shallow waters versus adult gizzard shad that stay in deeper waters, near the bottom.
These fish spawn at night during the spring and summer in shallow waters over rocky substrate. The eggs are scattered and adhere to objects on the bottom substrate until hatching 2 to 4 days later. The juveniles obtain sexual maturity in 2 to 3 years and have a lifespan of approximately 4 to 6 years.
Juvenile gizzard shad are planktivores, eating protozoans, small crustaceans, Chlorophyta, and Chrysophyta.
Adults are primarily bottom filter-feeding detritivores, acquiring food from aufwuch assemblages in littoral areas (Natureserve, 2009).
Gizzard shad are often used by anglers as a bait fish.
B-9

Bigmouth buffalo-Ictiobus cyprinellus The bigmouth buffalo is fairly common throughout North America from the Mississippi River basin stretching from Louisiana to Ohio, to southern Michigan, Wisconsin, Minnesota, North Dakota, Montana, the lower Great Lakes basin, the Hudson Bay basin (Nelson River drainage) and Saskatchewan.
This species preferred habitat is found in the main channels, pools, and backwaters of small to large sluggish rivers; oxbows, bayous, reservoirs, and lakes. The bigmouth buffalo is tolerant of low oxygen levels and high temperatures. These fish prefer to spawn after spring floods, doing so in flooded marshes and river bottoms, or in tributary streams. Eggs sink and adhere to vegetation or other objects (Natureserve, 2009).
Both juvenile and adult members of this species rely mainly on planktonic and bottom dwelling invertebrates as a food source.
Channel catfish-Ictalurus punctatus Channel catfish occur mostly in the central drainages of North America, from southern Canada to northern Mexico, historically. It has been widely distributed throughout the United States as well as other countries.
This species prefers clean, well-oxygenated water of rivers and streams, but will occur in ponds and lakes as well. They occur from clear, rapid flowing waters over firm bottoms, to turbid slow moving water over mud substrates.
Channel catfish have been known to migrate hundreds of miles throughout their lifetime. They generally spawn between April and July when temperatures are about 27 degrees Celsius. Females lay up to 20,000 eggs in a nest on holes dug in sandy substrates. Males then guard and fan over the nest during the 3-8 day incubation period. Larval development lasts about two weeks, and schools of larvae may persist for weeks after leaving the nest. Sexual maturity is reached anywhere from 2-8 years, and adults may reach over 130 cm and live up to 16 years.
Juvenile channel catfish eat mainly small invertebrates and insects, and prey increasingly on crayfish and fishes as they grow. Adults are mainly piscivorous, but will feed upon insects, small mammals, and vegetation (Natureserve, 2009).
The channel catfish size make it a highly sought after sport fish. They also have significant commercial value to fisherman in Lake St. Clair and Lake Erie.
White bass-Morone chrysops The white bass is a freshwater member of the sea bass family. It is distributed across the United States and eastern Canada, specifically in Lake Michigan, Lake Huron, Lake Ontario, and Lake Erie. This fish prefers open water habitat in lakes and some large rivers.
White bass spawn in spring with each female releasing between 242,000 and 933,000 eggs in shallower water, which sink and adhere to the bottom substrate. Soon after spawning, the parents abandon the eggs and move to deeper waters. The eggs hatch approximately 4.5 days later and the young fish remain in shallow water for a period of time before migrating to deeper areas. White bass usually do not live past 7 years of age. They are carnivores, eating microscopic crustaceans, insect larvae, and other fish.
It can be easily caught and is an excellent eating fishing causing it to be a highly sought after game fish.
B-10

Freshwater drum-Aplodinotus grunniens This species of drum is widely distributed throughout North and Central America. It ranges from the St.
Lawrence, Great Lakes, Hudson Bay, and Mississippi River Basins, Gulf Coast drainages, south through eastern Mexico and down to Guatemala.
Freshwater drum occur in a variety of habitats, but seem to prefer large, silty lakes and large rivers. They generally occur over mud bottoms in open water.
Spawning usually occurs in the spring or summer when water temperatures reach 19-22 degrees Celsius. They are generally pelagic spawners, utilizing open water far from shore, where their fertilized eggs float on the surface 1-2 days before hatching. Juvenile males generally reach sexual maturity in 2-4 years, while females take 4-6 years. Maximum life expectancy for this drum is ten years, with a growth potential of 95 cm.
Juvenile drum tend to feed upon minute crustaceans and insect larvae. Adults are mostly benthic foragers, and prey items include insect larvae, crustaceans, fishes, and bivalves (Natureserve, 2009).
Freshwater drums are harvested commercially in Lake Erie. This species is not a recreationally significant fish as anglers opinions of the species is mixed on the suitability for consumption.
Goldfish-Carassius auratus Native to Eurasia, the goldfish has been introduced throughout most of the contiguous U.S. and in parts of Canada. These fish prefer still water with abundant vegetation; lakes, reservoirs, ponds, rivers and quiet streams provide suitable habitat. They have no preference for clear or turbid water.
This species usually spawns in spring and summer, preferring to do so in shallow water so that eggs can be scattered in order to stick to objects. Eggs hatch in 2-14 days, depending on temperature and individuals reach sexual maturity sometime between 9 months and 4 years of age (Natureserve, 2009).
Both adult and juvenile goldfish are classified as herbivores/invertivores. They rely mainly on aquatic insects, mollusks, crustaceans, worms and vegetation for food.
White perch-Morone americana These fish belong to the family of temperate basses, a group of food and sport fish. White perch are native to the east coast but can be found in the Great Lakes area and are considered an exotic species. On the Atlantic coast they can be found in brackish waters, but have adapted to inland, freshwater lakes and tributaries. White perch prefer clear water and have no preference for substrate type.
They spawn in the spring by randomly releasing their eggs in the shallow waters of the Great Lake tributaries.
Eggs sink and stick to the bottom until hatching 4 days later. After hatching the young feed on microplankton and as they grow larger feed upon aquatic insects, invertebrates, other fishes, and the eggs of other fish species (Natureserve, 2009).
Though generally regarded as undesirable as a game fish in the Great Lakes, in the Eastern United States it is considered an excellent sport fish.
B-11

Lake whitefish-Coregonus clupeaformis th             th During the late 19 and early 20 centuries, large numbers of lake whitefish entered the Detroit River each year to spawn. Whitefish prefer rock, honeycomb limestone, gravel or sand for optimal spawning conditions. Reports indicate that the lower Detroit River was a prolific spawning area prior to the construction of the Livingstone Shipping Channel. The timing of this construction coincides with the degradation of whitefish populations in the river and western Lake Erie. The primary sources of food for the lake whitefish in the Western Lake Erie Basin are two small, bottom-dwelling organisms called Diporeia and chironomids. Lake whitefish have a narrow temperature tolerance, requiring cold, well oxygenated bottom waters throughout the summer in order to survive. They require relatively silt-free river or lake spawning areas for successful reproduction.
Lake whitefish are recognized as an indicator of ecosystem health and are an integral component of the Great Lakes food web. Recently, populations of lake whitefish were once again discovered in the Detroit River, but further studies are necessary to ascertain their presence in other tributaries of western Lake Erie.
Little information exists regarding whitefish life history, habitat requirements, and ecological niche in Lake Erie and its tributaries including the Detroit River. The Detroit River-Western Lake Erie Basin Indicator Project, sponsored by the EPA has identified a need for the collection of life history data for the lake whitefish and incorporated this need into ongoing monitoring and restoration studies on Lake Erie and the Detroit River (Natureserve, 2009).
Quillback-Carpiodes cyprinus The quillback belongs to the family Catostomidae or the sucker family. It has a wide distribution, including the Great Lakes-St. Lawrence River, Hudson Bay, and Mississippi River basins from Quebec to Alberta and south to Louisiana, west to Wyoming; Atlantic Slope drainages from the Delaware River, New York, to the Altamaha River, South Carolina, Gulf Slope drainages from the Apalachicola River, Florida and Georgia, to the Pearl River, Louisiana.
These fish are suited for both riverine and lacustrine habitats including pools, backwaters, and main channels, clear to turbid waters of creeks, rivers, and lakes. They may migrate up small streams and creeks during the spring and summer in order to find suitable spawning habitat. Both adults and juveniles can be classified as herbivores and invertivores, relying mainly on debris in bottom ooze, insect larvae and plant material for food (Natureserve, 2009).
Yellow perch-Perca flavescens The yellow perch belongs to the family Percidae or the perch family. It can be found in almost all 50 states as well as most of Canada. More specifically, the yellow perch is one of the most common fishes to Michigan waters, commonly found in Lake Erie, and is assumed to occur throughout the Detroit River, Swan Creek, and Stony Creek as well. They travel in schools, generally preferring the clear shallower waters of lakes or weedy backwaters of creeks and rivers. Yellow perch usually grow 6 to 10 inches in length and weigh between 6 and 16 ounces.
This species spawns in the spring in shallower waters over submerged beds of aquatic vegetation or over sand, gravel, or rubble. Eggs hatch in 10 to 20 days with males reaching sexual maturity at 2-3 years and females at 3-4 years. Their maximum lifespan is 10 years. Larvae and young yellow perch primarily feed upon zooplankton and as adults feed among plants, invertebrates, and other fishes.
Primary food sources for the yellow perch include mayfly larvae, caddisfly larvae, amphipods, chironomids, and zooplankton. This species feeds actively year round, leading the yellow perch to be recreationally targeted not only in warmer months, but also by ice fisherman in the winter. These large bodied, large-finned panfish have the distinction of being the most frequently caught game fish in Michigan.
B-12

In the late 1980s and early 1990s, after a 40 year absence due to pollution and eutrophication, large benthic invertebrates including mayfly larvae, caddisfly larvae, and amphipods recolonized western Lake Erie. When burrowing mayflies began to recolonize the lake as water quality improved, the yellow perch population began to rebound as well. Of high value economically, the yellow perch is also an indicator of water quality and ecological conditions on Lake Erie. Yellow perch are also beneficial because they feed on the round goby, a non-native, invasive species (Natureserve, 2009).
Walleye-Sander vitreus Walleye are the largest member of the perch family. They can be found in all the Great Lakes as well as across the central-east United States and up into Canada. It ranges in length from 13 to 25 inches and weighs 1 to 5 pounds. Walleye can be found in a variety of large bodies of freshwater including lakes, pools, backwaters, rivers and flooded marshes. They prefer deep waters and avoid bright light.
This species spawns in late spring or early summer in turbulent rocky areas in rivers, coarse gravel shoals in lakes or flooded marshes. Eggs are dispersed, then abandoned and will hatch approximately 26 days later. It has been documented that adults may migrate up to 160 km between spawning habitat and non-spawning habitat. Male juvenile walleye will reach sexual maturity in 2 to 4 years and females 3-8 years. Young walleye up to 6 weeks of age mainly eat copepods, cladocera, and small fishes while adults feed upon fishes and larger invertebrates (Natureserve, 2009).
This popular game fish can be caught year round in the Great Lakes and it sought for its excitement to catch and its favorable taste.
Largemouth bass-Micropterus salmoides The largemouth bass is widely distributed throughout North America, from the St. Lawrence, Great Lakes, Hudson Bay, and Mississippi River basins, as well as the Atlantic drainages from North Carolina to Florida, to northern Mexico. This popular gamefish has been introduced widely throughout the United States and the rest of the world, where it is sometimes considered to have had adverse ecological impacts.
This bass will inhabit clear waters of lakes, ponds, reservoirs, and swamps. Largemouths may also be found in the pools or backwater areas of creeks and rivers. They are usually associated with muddy bottoms and aquatic vegetation as well.
Largemouth bass spawn in spring and summer when the water temperature reaches at least 15 degrees Celsius. Males become aggressive and territorial as they dig nests in shallow water. After the female deposits eggs in the nest, the male guards and fans the eggs, which hatch within five days. The hatchlings will reach sexual maturity in 2-5 years, and may attain sizes of nearly 100cm with a life expectancy up to 23 years.
This species feeds mainly upon zooplankton as fry. As the juvenile grows it begins to prey upon insects, crustaceans, and fish fry. Adults are mainly piscivorous, but will feed upon crawfish and frogs as well.
Largemouth bass have also been shown to be cannibalistic and do not feed while spawning (Natureserve, 2009).
The largemouth bass is a major sport fish in the Great Lakes. Its excellent fighting ability and good taste makes it a valuable resource for recreational fishing.
Smallmouth bass- Micropterus dolomieu The smallmouth bass is widely distributed throughout North America, from the St. Lawrence-Great Lakes, Hudson Bay (Red River) and Mississippi River basins from southern Quebec to North Dakota and south to northern Alabama and eastern Oklahoma. This gamefish has been widely introduced throughout U.S., southern Canada, and in other countries.
B-13

This species prefers large clear lakes (especially in north) and clear midorder streams and rivers with many large pools, abundant cover (rocks, shelves, logs, etc.), and cool (20-27 C) summer temperatures. While individuals living in lacustrine habitats prefer shallow waters, adults are known to seek shelter of pools or deep water during the day.
Smallmouth bass spawn in shallow water in lakes or quiet areas of streams. In some situations, lake populations may move a short distance up a stream to spawn. Eggs are laid in nests made by the male, usually on a gravel or sand bottom at depth of about 1 m (less than 4 m) near protective cover.
This bass relies mainly on crustaceans and aquatic insects as a food source (e.g., chironomid larvae and pupae) until they are about 5 cm in length, when they start feeding heavily on other fishes. Crayfish, amphibians, and insects often become dominant foods of local populations or seasonally. Adults rely almost entirely on other fishes as prey as long as their availability is adequate (Natureserve, 2009).
The smallmouth bass is a popular sport fish in the Great Lakes area.
Rainbow trout-Oncorhynchus mykiss The rainbow trout is widely distributed throughout North America, from streams along the Pacific coast to the Great Lakes region. It can be found in almost every state in the lower 48 and throughout most of Canada.
This fish is capable of surviving in a wide range of habitats, typically preferring areas where dissolved oxygen concentration is at least 7 ppm. Anadromous populations occur in coastal rivers whereas some resident populations now inhabit small headwater streams, large rivers, lakes, and reservoirs. These fish often inhabit cool clear lakes and cool swift streams with silt-free substrate and deep low velocity pools for wintering habitats.
Rainbow trout usually spawn in the spring and summer months, depending upon water temperature. Lake populations will usually move to streams for spawning where eggs are laid in a gravel depression made by the female. With a normal life-span of 5-6 years, a single anadromous rainbow trout might migrate hundreds of miles from the coast into the headwaters of a stream.
In lakes, these fish feed mostly on bottom-dwelling invertebrates and other small organisms such as aquatic insects, amphipods, insects, worms, fish eggs and, occasionally, small fish and plankton. In streams, they tend to feed primarily on drift organisms. Rainbow trout might occasionally ingest aquatic vegetation (likely in effort to consume attached invertebrates).
Rainbow trout are an important game fish throughout North America (Natureserve, 2009).

==Dear Mr. Quraishi:==

Part LA.16.a. ofNPDES Permit No. MI0037028 for the Fermi 2 Power Plant requires that "on or before April 1, 2007, the permittee shall submit the Proposal for Information Collection in Sl25.95(b)(l) prior to the start of information collection activities or show compliance with the Compliance Alternative in S125.94(a)(l)(i)". This compliance alternative requires that a facility either has or will reduce intake flow commensurate with a closed-cycle recirculating system.Ifthefacility-meets this requirement it is deemed to have met the applicable performance standards and is not required to demonstrate further that the facility meets the impingement mortality and entrairnnent performance standards in S125.94(b). In addition, the permittee is not subject to the requirements in S125.95, S125.96, Sl25.97, or Sl25.98. The Fermi 2 Power Plant has achieved compliance with Compliance Alternative 125.94(a)(l)(i) through the use of two natural draft cooling towers (see attached water flow diagram).
Further details of source water physical data, cooling water intake structure data and cooling water system data pursuant to 40 CFR 122.2l(r) (2),(3) and (5), respectively, will be provided on or before April 4, 2009.

NPDES Permit No. MI0037028

==Dear Mr. Mroczkowski:==

In accordance with Part I.A.1.e and Part I.A.1.f of the DTE Electric Company - Enrico Fermi 2 Power Plant (ENFPP) National Pollution Discharge Elimination System (NPDES) Permit No. MI0037028 (Permit), ENFPP requests to reduce monitoring frequency for Total Copper and Total Phosphorus from monthly to quarterly.
Total Copper As of November 2019, ENFPP has submitted 12 months of data, as required per the Permit.
Attachment 1 summarizes 13 months of Total Copper measurements (November 2018-November 2019). Throughout this period, Total Copper loading and concentration has remained well below Permit limits. Attachment 2 provides summary statistics on 12 months of data (November 2018-October 2019). The maximum value for Total Copper loading during this time is 3.9 lbs/day, about 26% of the Permit limit of 15 lbs/day. Additionally, the maximum value for Total Copper concentration is 14.1 ug/L, about 35% of the Permit limit of 40 g/L. A monitoring reduction from monthly to quarterly is appropriate because it is unlikely that Total Copper limits will be surpassed, and quarterly measurements will accurately represent Total Copper loading and concentration.
Total Phosphorus Attachment 1 summarizes 13 months of Total Phosphorus measurements (November 2018-November 2019). Throughout this period, Total Phosphorus loading and concentration has remained well below Permit limits. Attachment 2 provides summary statistics on 12 months of data (November 2018-October 2019). The maximum value for Total Phosphorus loading during this time is 34 lbs/day, about 9% of the Permit limit of 380 lbs/day. Additionally, the maximum value for Total Phosphorus concentration is 0.11 mg/L, about 11% of the Permit limit of 1.0 mg/L. ENFPP is currently using two phosphorus-containing water treatment additives discharged to Outfall 001B that reach Outfall 001A, Depositrol BL5400 and Flogard MS6222. These two additives are highly diluted at levels around 0.12 ppm in the final discharge to Outfall 001A. Based on the above information, it is unlikely that Total Phosphorus limits will be surpassed, and quarterly measurements should sufficiently represent Total Phosphorus loading and concentration.
One Energy Plaza, Detroit, Ml 48226-1221 dteenergy.com

Additionally, phosphorus-containing water treatment additives currently in use are used infrequently and at low concentrations. Thus, a monitoring reduction from monthly to quarterly is appropriate.
