Cook Nuclear Plant NPDES Permit M10005827 Application

Dear Sir or Madam:

Indiana Michigan Power Company (I&M) is hereby submitting an Industrial and Commercial Wastewater Discharge Application for renewal of the Donald C. Cook Nuclear Plant National Pollutant Discharge Elimination System (NIPDES) Permit. The enclosed application is being submitted on or before April 4, 2008, as required by the current permit..By letter dated January 24, 2008 (enclosed), the Michigan Department of Environmental Quality (NMIl DEQ) notified I&M to reapply for NPDES Permit, MI0005827.

This letter stated that the January 2008 revision of the permit application was required to be used and was available electronically on the internet.

I&M obtained a copy of the application from the intemet in January 2008. A review of the completed application revealed that it contained an erroneous revision date in the footer of the application of 11/2007. In a telephone conversation on March 26, .2008, between I&M staff and MI DEQ staff, it was determined that the application dated November 2007 is the January 2008 revision and should be considered as such. MI DEQ staff indicated that since the initial internet posting of the January 2008 revision, typographical corrections have been made to the revision including the revision date in the footer of the document.By letter dated February 21, 2007 (enclosed), I&M requested to use, in the permit application submittal, data from representative outfalls to. characterize effluent characteristics for similar outfalls.

By letter dated February 12, 2008 (enclosed), MI DEQ granted permission of this request. The enclosed application permit reflects this allowance for the outfall data.The NPDES Permit Application, General Provisions, step 5, discusses requirements for quantification levels of select parameters identified in the Appendix, Table 7. I&M's contracted lab was unable to meet the required quantification levels for Silver, Selenium, and Arsenic for Outfall OOB. In telephone DEQ -Water Bureau CC 2008-245 Page 2 conversations in February between I&M staff and MI DEQ staff, lI\ DEQ staff stated that completion of the application with the current analyzed values and/or a value of less than the quantification level achieved would be acceptable to consider the application complete.

MI DEQ still requires these parameters to be analyzed at the required quantification levels and agreed to accept the analysis riesults for the application at a later date. I&M has re-sampled these parameters and will submit the analysis data, using the specified quantification levels, to MI DEQ by May 31, 2008.By letter dated February 27, 2007'(enclosed), I&M notified MI DEQ that the signature authority for NPDES and groundwater related issues includes, Jon H. Harner, Environmental Manager.In accordance with Michigan Act 451, please find an enclosed check for the Application Fee of $750.Should ýou have any questions, please contact me at (269) 465-5901, extension 2102, orBlair Zordell at (269) 465-5901, extension 2006.Sincerely, Jon H.

Donald C. Cook Nuclear Plant NPDES Permit No. MI0005827 We are currently preparing the Wastewater Discharge Permit Application to renew our current NPDES operating permit. As noted in Section IIIB -Industrial and Commercial.

Wastewater, Part B. Outfall Information Item B.3, paragraph 5 contains instructions to request permission to use a single sample for similar outfalls.We request that Outfall 001 be used as a representative sample for Outfalls 002 (Unit Two Noncontact Cooling Water) and Outfall 003 (De-icing Mode). Outfalls 002 and 003 are identical to Outfall 001, the source of these Outfalls is Lake Michigan, similar waste streams enter each Outfall prior to discharge.

In addition, we are requesting Outfall 00B (Unit Two Steam Generator Blowdown) to be used as a representative sample for Outfall OOA (Unit One Steam Generator Blowdown), and Outfall 00C (Plant Heating Boiler Blowdown).

Outfall OOA and Outfall 00B are identical discharges, with the exception that Outfall O0A originates from the Unit One Steam Generators, and Outfall 00B originates from the Unit Two Steam Generators.

Outfall OOC is boiler blowdown, the supply water is from the same source. The treatment chemicals/ranges in the three systems are hydrazine/(0-400 ppm), ethanolamine/(0-100 ppm), carbohydrazide/(0-40 ppm). The current auxiliary boiler on the site is undergoing repairs and will be unavailable for sampling in the upcoming year.If you have any questions, please contact me at (269) 465-5901, ext. 1153.Sincerely, J hn P.

SECTION I, ITEM 10 Cont'd N-PDES Waste Stream Narrative This narrative describes all outfalls discharging to Lake Michigan.

Flows are based on a review of previous NPDES applications, Plant system descriptions, or previously submitted Discharge Monitoring Reports (DMR). The chemical additives described below may include a manufacturer's name as an example of the type of product used in a specific system. Indiana Michigan Power may substitute vendors of chemical additives provided that the chemical ingredients are similar. Discharge values are based on maximum release rates and volumes, dilution rates are based on a minimum number of pumps running.OUTFALL 001 -Unit 1 Circulating Water Discharge Outfall 001 is a non-contact cooling water discharge.

The majority of non-contact cooling water (Circulating Water System, -690,000 GPM) is used to condense the steam exhausting from steam driven turbines.

Non-contact cooling water is drawn from Lake Michigan approximately one-half mile from shore through three 16 ft. diameter tunnels. Water enters the tunnels via intake cribs at an approximate velocity of 1.3 feet per second. The water enters to a forebay where it is screened to remove large debris that may be entrained in the water. It is routed through the Unit 1 condensers and then discharged to Lake Michigan through a 16 foot diameter tunnel. The water exits the tunnels through high velocity discharges at a rate of approximately 13 feet per second approximately 1/4 mile from shore. Outfall 001 also includes internal Outfalls (as designated by the Michigan Department of Environmental Quality)Steam Generator Blowdown (OOA, OOB), Plant Heating Boiler (OOC), Reverse Osmosis Unit (OOG), and the Turbine Room Sump Emergency Overflow (OOH) described in detail later in this document.Outfall 001 also may contain the effluent flow from both Units' Essential Service Water (ESW) systems, both Units' Non-Essential Service Water (NESW) system, and monitor tank releases.

ESW (-40,000 GPM) is Lake Michigan water taken from the forebay that is used to provide cooling to safety-related equipment.

NESW (- 18,000 GPM) is also Lake Michigan water taken from the forebay used for I non-contact cooling for various plant systems including oil coolers, a source of water for the demineralized makeup system (MUP), and a water supply for non-safety related equipment.

Monitor tank releases (-15,000 to 20,000 gallons per event) are regulated by the NRC and consist of wastewater from various system and equipment leakage that may be generated within the auxiliary building area.Minor leakage from systems containing lube oil, hydrazine, carbohydrazide, ethanolamine or closed-loop cooling systems containing a maximum concentration of gluteraldehyde (100 ppm), methyl (bis)thiocyanate (10 ppm), tolyltriazole (60 ppm), Molybdate (1000 ppm), and nitrite (1200 ppm), may be discharged via monitor tank releases.The non-contact cooling water for the Circulating Water, the ESW and the NESW, and Miscellaneous Sealing and Cooling Water Systems is treated for biological control using sodium hypochlorite.

This same water is periodically treated using a non-oxidizing biocide to eradicate zebra mussels from the cooling systems. The biocides (Betz Spectrus CT-1300, Calgon H-130M, Calgon EVAC and NALCO Macro-Trol 9380) are polyquats, and are used as required to protect plant systems while meeting water quality based effluent limits. The treatments can be directed to various critical plant systems from the intake structures through the entire plant cooling system, including the Circulating Water System, ESW and NESW systems and other non-contact cooling water. The biocide may be added to the systems via a chemical injection pipeline through a ring header located inside the intake crib, or directly applied at a specific system. A chemical injection pipeline may be installed and is designed to feed chemicalsfrom inside the plant. The intake chemical injection header may be stored with chemical inside the pipe to prevent zebra mussel infestation.

The header may also be leak checked using approved dyes such as fluorescein, or other indicators such as Nalco Trasar 23299. Non-contact cooling systems biocide treatments are dependent upon zebra mussel infestation.

Concentrations and chemical feed points are chosen to minimize the amount of biocide required and to maximize the efficacy on zebra mussels.Bentonite clay may be added to detoxify the biocide prior to discharge.

The plant non-contact cooling water systems may be treated concurrently or individually to allow more efficient use of chemicals.

Plant systems are treated to assure safe operation of the nuclear generating units.The piping used to apply chemicals is regularly cleaned of calcium carbonate scale buildup. A small amount of weak acid cleaner such as Betz FerroQuest FQ LP 7200 may be used to remove accumulated carbonate scale deposits.

The accumulated deposits will be discharged via Outfalls 001/003. Circulating water will dilute the weak acid prior to discharge to Lake Michigan.2 Condensate flushes are performed periodically to purge the plant's secondary water system from layup chemistry specifications during shutdown conditions to startup chemistry specifications prior to startup of the unit. Water containing up to 4 ppm hydrazine

[Betz Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H], 10 ppm carbohydrazide (NALCO 1250 plus, or equivalent), 100 ppm ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM00 1), is overboarded to Outfall 001 as required to remove contaminants to meet desired startup secondary Chemistry specifications.

This flowrate averages 70 GPM, but may reach 600 GPM for short periods of time. The flowrate is dependent on chemistry specification parameters and makeup water availability.

The maximum output from the MUP is approximately 600 GPM or 864,000 GPD. (See Outfalls OOA, 00B for further description.)

Monitor tanks receive treated water from the auxiliary building radioactive waste removal system and other sources such as ice production and removal processes from the ice condenser systems and other radioactively contaminated wastes generated at the facility.

This system handles wastes generated from the reactor coolant pump seal leakoffs, the refueling cavity water, equipment leaks, floor drains, valve stem leakoffs, system sampling, and waste sample solutions.

It also handles laboratory wastes from the radiochemistry analysis in the hot chemical laboratory, system equipment drains, non-contact cooling water, ice production/removal and decontamination processesand any contaminated liquid waste generated in the auxiliary building area. The wastes are collected in one of several tanks and are treated when enough water is collected.

The treatment utilizes a demineralizer system to minimize radioactive contaminants.

A small amount of wastewater may bypass the treatment because it cannot be processed by resin.Other special drains of non-radioactive process water systems such as-Component Cooling Water system flushes with biocides such as gluteraldehyde (100 ppm), methyl (bis) thiocyanate (10 ppm), tolyltriazole (60 ppm), Molybdate (1000 ppm) and nitrite (1200 ppm), and borated icemaking/ice removal operations, can be routed directly to the plant's monitor tanks without treatment.

For maintenance purposes to prevent microbial growth, Component Cooling Water flushes are performed generating approximately 281,000 gallons per year of flushwater to the monitor tanks.Borated icemaking/ice removal operations occur for maintenance of the plant's ice condenser systems.This process produces a solution of sodium tetraborate (approximately 2200 ppm as boron) that can be drained to the monitor tanks. This process takes place approximately every 18 months and may produce up to 70,000 gallons of sodium tetraborate solution.

Both the treated wastewater and the special drains are accumulated in the monitor tanks and sampled to ensure the waste meets the radiological requirements prior to being discharged into the Circulating Water System.Periodically, due to equipment leaks and/or system upsets, a waste stream is generated that contains radioactively contaminated ethylene glycol and water. Incidental amounts of ethylene glycol generated from equipment leaks may be drained directly to the monitor tanks or treated by the radwaste processing system. Small amounts of ethylene glycol may be discharged to outfalls 001, 002, or 003.Sulfur hexafluoride gas (SF6) is utilized in the non-contact cooling water systems at the plant to detect leaks in various components such as the condensers.

The gas is injected in the cooling water stream and discharged to outfalls 001, 002 or 003 at less than 54 ul/1.Aryl sulfate liquid (NALCO Trasar 23299) is utilized in the non-contact cooling water systems at the plant to determine flow through Various parts of the system. The liquid is injected into the service water system to reach a target concentration of approximately 2 mg/l. The service water is discharged to Outfalls 001, 002, or 003, which would, in turn, dischaige at less than 0.15 mg/I. The liquid is also injected into the circulating water system to reach a target concentration of approximately 2 mg/l.Control Room Air Conditioning (CRAC) testings Approximately 1440 gallons/yr.

of CRAC water may mix with ESW and then be discharged to the forebay during a monthly test of the system. CRAC water is demineralized water, and may contain up to: 2000 ppm nitrite [Calgon LCS 60, Betz Corrshield NT 4205, BETZ CORRSHIED NT 4201, Betz Corrshield NT 4203, or equivalent], 100 ppm gluteraldehyde

The three storm drains are designed to route accumulated stormwater from this small roadway to the forebay below. A small amount of de-icing compound used on this section of road could potentially enter these small (Approximately 8") gratings.

Screened material collected from the plant's intakes is also stored in this area in designated trash dumpsters.

Fish exudiates are now drained to the forebay as recommended by the MDEQ stormwater and NPDES inspection team (M. Fields and J. Molloy 1997).During upset conditions it is possible to overflow the contents of the Turbine Room Sump (See Outfall OOH) to Outfalls 00 1, 002 and/or 003 if the flow path to the on-site absorption pond cannot be used.OUTFALL 002 -Unit 2 Circulating Water Discharge Outfall 002 is a non-contact cooling water discharge.

The majority of non-contact cooling water (Circulating Water System, -920,000 GPM) is used to condense the steam exhausting from steam driven turbines.

Non-contact cooling water is drawn from Lake Michigan approximately one-half mile from shore through three 16 ft. diameter tunnels. Water enters the tunnels via intake cribs at an approximate velocity of 1.3 feet per second.

A portion of the flow from Outfall 001 and /or Outfall 002 is directed through the center intake tunnel to temper the intake water and prevent ice buildup on the intake structures which could restrict intake flow. The velocity at the other two intake structures during de-icing mode increases to approximately 1.9 feet per second. Discharge velocity will be less that 13 feet per second since a portion of the discharge is routed out the center intake tunnel.The Essential and Non-Essential Service Water System (ESW and NESW) may be recirculated with a combination of Circulating Water Pumps in service to raise the forebay temperature to prevent frazil ice formation during cold weather periods. During shutdown conditions when normal operating heat addition is not available, portable heat.addition units may be placed in the forebay to prevent frazil ice formations that may prevent flow to safety systems in the plant.OUTFALL OOA -Unit 1 Steam Generator Blowdown The steam generators (part of the secondary water system) require ultra high purity water for operation.

Makeup water used in the steam generators is withdrawn from the intake forebay (or from Lake Township water supply or a blending of both sources) and treated so most natural impurities are removed through sedimentation, filtration, reverse osmosis, and demineralization.

Impurities concentrate in the steam generators as the water is turned to steam and must be removed to protect the steam turbines and 9 heat transfer surfaces of the steam generators.

The impurities are removed by continuously draining a portion of the water from the steam generators in a process called "blowdown".

In the steam generator, steam is separated from the water, further heated, and then routed to the turbines.When the steam'separates from the water, the impurities remain in the water, concentrating in the steam generator.

Blowdown consists of two forms, a liquid portion (700 gpm max) and a wet steam portion, which is exhausted to the atmosphere.

The liquid portion of the steam generator blowdown is discharged to the screenhouse forebay either directly (Nornal Flash Tank), or after processing through mixed bed demineralizers.

Impurities in this discharge may consist of small quantities of insoluble iron and copper or impurities from the Circulating Water System used to cool the condensers should condenser tube leaks occur. Steam generator additives consist of ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM001) for pH adjustment, hydrazine

[Betz Cortrol OS5035, Betz Cortrol OS501 0, NALCO 19H] and/or carbohydrazide (NALCO 1250 plus, or equivalent) for oxygen scavenging.

When the units are not operating, the steam generators are placed in wet layup conditions to protect against corrosion during storage. Layup water is periodically discharged through the outfall to the Circulating Water Forebay. The layup water contains a maximum concentration of 400 ppm hydrazine[Betz Powerline Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H] and/or 40 ppm carbohydrazide (NALCO 1250 plus, or equivalent), and /or 100 ppm ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM001).

The waste strength of this discharge is reduced through mixing with Outfalls 001, 002, or 003.During the Sludge Lancing Process, demineralized water or secondary water is used to pressure clean the steam generators during outage periods. The water is recirculated through temporary filters to remove entrained solids. The major constituent of the solids is iron oxide from the steam generators.

The water is then returned to the steam generators and can be drained to Outfalls O0A, O0B, to Outfall 001, 002, 003, OOD or OOH. The suspended solids are analyzed for radioactivity prior to disposal.OUTFALL OOB -Unit 2 Steam Generator Blowdown The steam generators (part of the secondary water system) require ultra high purity water for operation.

The suspended solids are analyzed for radioactivity prior to disposal.11 OUTFALL OOC -Plant Heating Boiler A heating boiler (150,000 lb/hr capacity) operates to supply plant heating and auxiliary steam when Unit 1 and/or Unit 2 are out of service. The boiler is also fired periodically for testing purposes to ensure its availability.

During periods when not in operation, the heating boiler may be stored full of treated boiler water containing up to 400 ppm hydrazine

[Betz Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H] or 40 ppm carbohydrazide (NALCO 1250 plus, or equivalent) for oxygen scavenging and or 50 ppm ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM001) for corrosion protection.

Prior to use, this "wet lay-up" water is drained to Outfall OOC via blowdown, which discharges to the intake forebay. The volume drained is approximately 600 gallons. This boiler may also be occasionally drained for maintenance activities, approximately 6,000 gallons of treated boiler water would be directed to Outfall 00C or OOD/OOH for such purposes.Impurities from the boiler water consisting primarily of insoluble iron and copper are discharged via blowdown (30 GPM-) to the intake forebay during operation as needed for Chemistry control. Boiler water treatment additives consist of up to 15 ppm ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM001) for pH adjustment, up to 150 ppb hydrazine.[Betz Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H] and/or 150 ppb carbohydrazide (NALCO 1250 plus, or equivalent) for oxygen scavenging.

Just after boiler shutdown, the boiler may be placed in dry layup. The boiler contents (up to 6,000 gallons) are drained via blowdown to the intake forebay. Boiler water treatment additives consist of up to 3 ppm ethanolamine (Betz Powerline 1440, Betz Powerline 1480, NALCO 92UM001) for pH adjustment and up to 150 ppb hydrazine

[Betz Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H]and/or 150 ppb carbohydrazide (NALCO 1250 plus, or equivalent) for oxygen scavenging.

The boiler is then dried out and stored empty. This process saves on chemicals and prevents unnecessary discharge of wet layup chemicals.

A smaller boiler may be installed to provide back-up heat if the permanent heating boiler was out of service. This back-up boiler may be located outdoors on the West Side of the turbine building.

The blowdown line is directed to the Unit One forebay, near the same discharge point as the permanently installed heating boiler.12 The same boiler treatment chemistry will be maintained in the back-up boiler as is used in the permanent heating boiler. The back-up boiler treatment additives consist of ethanolamine (Betz Powerline 1440, Betz Powerline i480, NALCO 92UMOO 1) for pH adjustment, and hydrazine

[Betz Powerline Cortrol OS5035, Betz Cortrol OS5010, NALCO 19H] and/or carbohydrazide (NALCO 1250 plus, or equivalent) for oxygen scavenging.

This boiler may be occasionally drained for maintenance activities, approximately 6,000 gallons of treated boiler water would be directed to Outfall OOC for such purposes.Impurities from the boiler water consisting primarily of insoluble iron and copper are discharged via blowdown (30 GPM maximum) to the intake forebay during operation as needed for Chemistry control.OUTFALL OOG -Reverse Osmosis System The Reverse Osmosis System (RO) is used to assist in the removal of dissolved solids from the lake water prior to demineralization.

Reject water flow is directed to the forebay, which leads to Outfalls 001, 002, and 003. Reject water flow rates may reach up to 0.366 MGD. The RO system must maintain very clean membranes to assure efficient operation and purity of water. Several methods are used to maintain this level of cleanliness from scale and biofouling.

Hydrochloric acid or sulfuric acid is fed at approximately 1.3 GPH continually when the RO is in service to lower the pH to reduce the scaling tendencies of the water. The reject water from the RO unit consists of concentrated Lake Michigan water and a small amount of acid that inhibits scale buildup in the membranes.

Approximately once per month, a flush is performed using approximately 1,000 gallons of a nominal.0.05% hydrochloric acid solution.

This is followed with approximately 1,000 gallons of a nominal 0.1%sodium hydroxide solution.

This flush will dissolve any scale that deposits on the membranes.

The total amount of flushing solution will average approximately 5,000 gallons per event. Sodium bisulfite is used to preserve the membranes during long-term shutdown periods. Approximately 15 lbs. of sodium bisulfite per year is used in this manner.The chemical cleaning involves several steps and may contain citric acid, hydrochloric acid, phosphoric acid, sodium hydroxide, and a neutral pH detergent.

The periodic cleaning process averages approximately 10,000 gallons per event, diverted either to the Turbine Room Sump (Outfall 001/O0D), through the Neutralization Tank to the Turbine Room Sump (Outfall 00H/00D), or to the Circulating Water Forebay (Outfall 001, 002, or 003).13 OUTFALL OOH -Turbine Room Sumo Emergencv Overflow Utility wastewater from within the plant is discharged via the turbine room sump (TRS) into an on-site absorption pond (Outfall 0OD). The nor-mal disposition of these wastewaters is to an on-site absorption pond, which eventually Vents via groundwater to Lake Michigan.

In the unlikely event that the normal flow path to the absorption pond is not available, the overflow line (Outfall OOH) will direct the TRS flow to the plant's intake forebay. The wastewaters associated with this Outfall include: Wastes from the makeup water treatment system.* NESW: (144,000 GPD) The main contributor to this waste stream is the degassifier pump seal water.Non-Essential Service Water (NESW) from Lake Michigan supplies the vacuum degassifier pumps which utilize up to 100 GPM to remove non-condensable gases (primarily carbon dioxide and oxygen) from the makeup plant water and exhausts them to the atmosphere.

Pre-filter backwash: (Estimated 98,000 GPD) Six pre-filters are backwashed with Lake Michigan water to remove the suspended matter captured on the filter media. Alum solution (aluminum sulfate 0.5 lb. per gallon) is added to the pre-filter influent as a flocculent.

The alum is added via a feed pump. Approximately 50 lb./day of alum is used in this process. The alum contained in the backwash is discharged in the form of insoluble aluminum hydroxide.

Carbon filter backwash: (Estimated 42,000 GPD) Carbon filters are periodically backwashed with Lake Michigan water to the TRS. These filters primarily remove organics, chlorine and small amounts of iron.* Demineralizer regeneration: (Estimated 50,000 gallons per regeneration) occurs 2-4 times per month when the RO is in service and more often when it is not in service. Dilute sulfuric acid and sodium hydroxide used by the system to regenerate the resin. Dilute sulfuric acid, sodium hydroxide, and contaminates from the demineralization process is discharged to the neutralization tank or TRS.The pH is then adjusted to between 5.5 and 9.0 with sulfuric acid, or sodium hydroxide prior to discharge.

• MIJP Neutralization Tank provides a place for demineralization regeneration wastes, and Reverse Osmosis Unit cleaning flushes to be neutralized prior to being discharged to the TRS and ultimately 14 the absorption pond. When the MUP resin beds are regenerated, up to 50,000 gallons of regeneration chemicals, and backwash waters are processed in the neutralization tank. The Reverse Osmosis cleaning flushes average approximately 5,000 gallons per event. When the water is neutralized, it is pumped to the TRS via a 2,000 GPM neutralization waste pump." The Retention Tank is periodically blown down, discharging small volumes of solid material removed by settling.

The retention tank contains a mixture of Lake Township water and filtered Lake Michigan water waiting further processing by the Makeup Plant.* The Reverse Osmosis System (RO) Cleaning.

Normal reject water flow is to Lake Michigan via Outfall 00G. The RO system must maintain very clean membranes to assure efficient operation and purity of water. Several methods are used to maintain this level of cleanliness from scale and biofouling.

Hydrochloric acid or sulfuric acid is fed at approximately 1.3 GPH continually when the RO is in service to lower the pH to reduce the scaling tendencies of the water. The reject water from the RO unit consists of concentrated Lake Michigan water and a small amount of acid that inhibits scale buildup in the membranes.

Approximately once per month, a flush is, performed using approximately 1,000 gallons of a nominal 0.05% hydrochloric acid solution.

This is followed with approximately.1,000 gallons of a nominal 0.1% sodium hydroxide solution.

This flush will dissolve any scale that deposits on the membranes.

The total amount of flushing solution will average approximately 5,000 gallons per event. Sodium bisulfite is used to preserve the membranes during long-term shutdown periods. Approximately 15 lbs. of sodium bisulfite per year is used in this manner.The chemical cleaning involves several steps and may contain citric acid, hydrochloric acid, phosphoric acid, sodium hydroxide, anda neutral pH detergent.

The periodic cleaning process averages approximately 10,000 gallons per event, diverted either to the Turbine Room Sump (Outfall 00H), through the Neutralization Tank to the Turbine Room Sump (Outfall OOH), or to the Circulating Water Forebay (Outfall 001, .002, or 003).Waste from miscellaneous processes.

The lagoons discharge into the groundwater with the ultimate disposition venting to Lake Michigan.

The sludge removed from the digester tank basins is taken to a local POTW (public owned treatment works) for disposal or dewatered and stored as low level radioactive waste, and disposed of as appropriate.

29 To aid in the settling process, flocculents such as ferric chloride, pH controllers such as magnesium hydroxide, or polymers (such as Axchem AF4500) are added to the process. To selectively enhance biosolids, bioaugmentation nutrients (such as Bioprime Dosfolat) are added to the process. This is a nutrient that encourages the growth of beneficial microbes in the activated sludge. Sodium hypochlorite is added in small amounts to the process to control filamentous bacteria growth if needed. Sodium hypochlorite and detergent are also added to the sand filters to clean them periodically.

These are then backwashed into the equalization basin to be reprocessed by the SBR treatment process.Plant sanitary waste consists of shower and rest room facilities, and janitor washbasins located throughout the Plant's non-radiological property.

Kitchen wastes are generated from the plant cafeteria, the Cook Energy Information Center and Training buildings.

The chemistry training laboratory discharges to the sewage treatment plants through a limestone bed neutralization tank. The chemistry lab is used to train technicians on analyses performed in the plant.The discharge from the lab carries water and wastes generated while performing analyses and preparing laboratory standards including those on the attached list. The training building HVAC system also drains through the limestone bed.The wastewater treatment plant laboratory discharges to the sewage treatment plants. The discharge from the lab carries water and wastes generated from performing analyses and preparing laboratory standards used for compliance monitoring of the sewage treatment plant under groundwater discharge permit GW1810102.

Portable toilet wastes on the plant site may be collected anddischarged to the sewage treatment, plants.A biodegradable deodorant is used in the portable toilets. Sludge effluent waste may also be recycled through the plants to decrease the amount of sludge for processing when possible.Miscellaneous rinsing of waste receptacles and possible cleaning operations waste, utilizing various detergents, may be rinsed to the sewage treatment plants.30 Donald C.

The results of a toxicity test for one other North American freshwater aquatic species (other than a planktonic crustacean) that meets a minimum requirement of Rule 323.1057(2)(a) of the Water Quality Standards.

Examples of tests that would meet this requirement include a 96-hour LC50 for rainbow trout, bluegill, or fathead minnow.The required toxicity information (described in Items 7 and 8 above) is currently available in the Water Bureau files for the water treatment additives listed on the MDEQ's Internet page. To access that information, go to http://www.michigan.govldeq, click on "Site Map," at the bottom of the right column under Water Quality Monitoring, click on "Assessment of Michigan Waters." Under the Information heading, click on the "Water Treatment Additive List." If you intend to use one of the" water treatment additives on this list, only the information in Items 1 through 6 above needs to be submitted to the Water Bureau.Note: The availability of toxicity information for a water treatment additive does not constitute approval to discharge the water treatment additive.10. WHOLE EFFLUENT TOXICITY (WET) TESTS Have any acute or chronic WET tests been conducted on any discharges or receiving water(s) in relation to facility discharges within the last three.years? If yes, identify the tests and summarize the results on a separate sheet, unless the test has been submitted to the MDEQ in the last three years.

Cook Nuclear Plant Supplement to NPDES Permit M10005827 Application

Dear Mr. Syts,

On April 2, 2008, Indiana Michigan Power Company (I&M) submitted an Industrial and Commercial Wastewater Discharge Application for renewal of the Cook Nuclear Plant National Pollutant Discharge Elimination System (NPDES) Permit. At the time the application for renewal was submitted, I&M's contracted lab was unable to meet the required quantification levels for Silver, Selenium, and Arsenic for Outfall 00B. In subsequent telephone conversations between I&M staff and Michigan Department of Environmental Quality (MDEQ) staff, MDEQ staff agreed to accept the analysis results for the application at a later date.Enclosed is the supplemental data for Outfall OOB. This data meets the required quantification levels and completes our submittal of the permit application.

Also included for your information are the data sheets for Outfalls O0A and OOC, which are intended only to provide a complete set of data sheets.Should you have any questions, please contact me at (269) 465-5901,extension 2102, or Blair Zordell at (269) 465-5901, extension.2006.
