Amendment 3 has been prepared using the revised state application for= per the direction of your staff.
The current schedule is for Unit 2 to begin co=mercial operation in December of 1983 and Unit 1 in July of 198h.
As indicated in our previous submittals, there are a number of construction and preoperational testing discharges that vill occur upon co=pletion of the various plant systems prior to the start of plant co=ercial operation.
Several of these types of discharges will require authorization in the near future. We plan to work with your staff te develop a schedule which assures timely authorization of these discharges.
We ask that you assist us by assuring that the processing of these authorizations is given an appropriate priority.
Additionally, we believe it vould be appropriate at this time to reaffirm the understanding between your agency and the Nuclear Regulatory Co=ission concerning the processing of the Draft Environmental Statement as it relates to the processing of the draft NPDES Pemit.
It may also be advisable at this time to develop a process schedule that acco=odates the needs of both agencies.
To assure that each of the actions outlined above is initiated, as well as to address any questions you may have on Amendment 3, we request an opportunity to meet with you and appropriate members of your staff within two weeks.
Thank you for your consideration.
Yours very truly l

EXHIBIT I DESCRIPTION OF PROPOSED ENTERPRISE The Midland Plant Units 1 and 2, owned and to be operated the Consumers Power Company of Michigan, is sited partially within the se thern limits of the City of Midland, Michigan. Commercial operation of Unit 2 is planned for December,1983, and commercial operation of Unit 1 is planned for July 1984.
The 1235-acre plant site is on the south shore of the Tittabawassee River immediately across from the Dow Chemical Company's main industrial complex (see Figures 4 and 5).
The Midland Plant will generate approximately 1,300 megawatts of electricity for distribution to the applicant's system and that of the Michigan Power Pool of which the applicant and Detroit Edison Company are the principal partners.
In addition, up to 4,050,000 pounds per hour of process steam will be delivered to the Dow Chemical Plant across the river for use in chemical processes and heating.
The two reactors for the Midland Plant are pressurized-water type supplied by the Babcock and Wilcox Company. Each reactor will operate initially at a I
thermal power level of 2468 MWt and will be capable of an ultimate output of 2568 MWt.
Unit I will have a gross electrical capability of 505 MWe, and in addition will generate up to 3,650,000 pounds per hour of 175 psig steam and up to 400,000 pounds per hour of 600 psig steam for sale to Dow Chemical Company.
The gross electrical capability of Unit 2 will be 852 MWe.
In normal operation, Unit I will generate electricity and steam while Unit 2 will generate electricity. Unit 2 can provide steam when Unit 1 is shut down. The nominal operating pressure and temperature for both reactors is 2200 psig and 579 F.
The units are designed for a pressure of 2500 psig and a temperature of 650*F.
An exception is the pressurizer which is designed for a temperature of 670*F.
The steam and power conversion system is designed to accept steam from the nuclear steam system. One portion of this heat energy is converted to electrical energy by the turbine generators. A second portion of the heat energy is used in the process steam evaporators to generate process steam for Dow.
The circulating water system, utilizing cooling pond water, will dissipate the balance of the heat energy which is rejected by the turbine condenser.
Steam from the steam and power conversion systems is used in the process steam evaporators to generate process steam in a tertiary system for Dow.
The function of the process steam evapor-ters is to provide physical separation between the turbine plant cycle and the process steam delivered to Dow.
Steam from the Unit I steam generatore will pass through a two-flow, 1800 rpm, tandem-compound, high pressure turbine and then through moisture separator reheaters and combined intercept and stop valves to one double-flow low-pressure turbine which exhausts to the main condenser. Steam from Unit 2 will Amendment 3 miO681-0377a102-46 I-1 September 30, 1981
pass through a similar system, except that final flow will be to two double-flow, low pressure turbines which exhaust to a dual pressure condenser.
The Midland Plant Units 1 and 2 will generate electric power at 22 kV and 24 kV, respectively. This power will be fed through separate isolated phase buses to the unit main transformers where it will be stepped up to 345 kV transmission voltage and delivered to the switchyard on separate overhead lines.

EXHIBIT II SOURCE OF WATER PROCESS WATER All water for use as process water will be provided as follows:
1.
The Dow Chemical Company will provide feedwater to the evaporators (Node 20) in the process steam system. The steam thus produced is returned (Node 21) to the Dow Chemical Company for use in their process systems. This flow is expected to be continuous.
i 2.
The Midland Municipal Water District will supply the Midland Plant makeup l
demineralizer system (Node 23) which in turn will supply makeup water to the Midland Plant secondary steam cycle. The Plant will maintain a link I
to Dow demineralized water (Node 29) as an emergency backup.
i NONCONTACT COOLING WATER Water for use as cooling and condensing water will be withdrawn from the Tittabawassee River and pumped to the 880 acre recirculating cooling pond (Node 5).
The intake structure on the river will contain traveling screens, screen wash pumps, and trash racks.
The design of the intake structure has been found tentatively acceptable by the State of Michigan Department of Natural Resources pending post operational studies of the intake's efficiency and on-site velocity measurement (letter from Mr Robert J Courchaine, DNR, to Mr Paul C Hittle, Consumers Power Company, dated January 17, 1977).
Preliminary design rating of the makeup pumps was 200 cfs. The makeup pumps as built will be capable of withdrawing water from the Tittabawasee River for cooling pond makeup at a maximum capacity of 270 cfs subject to the following:
River Flow. efs Maximum Pond Makeup Rate, cfs

I Initial Pond Filling I
Water withdrawal from the Tittabawassee River for initial filling of the 12,600 acre-feet cooling pond began on April 7, 1978 and continued through May 4, 1978 (28 days).
Pond filling was resumed on November 8, 1978 with periodic pumping during 10 days in November, 19 days in December and 11 days in January 1979. Pond level has been maintained by filling activities during 4 days in March 1979, 1 day in November 1980, 4 days during December 1980 and 2 days in January 1981.
Amendment 3 miO681-0377b102-46 II-2 September 30, 1981 L
A Entrainment Monitoring of ichthyoplankton and macroinvertebrate_entrainment was conducted I
during the April and May 1978 pond fill activities and is reported in Survey and Evaluation of the Water Quality, Tittabawissee River, Near Midland,
)'
Michigan, 1978-1979 (CMU 1979). Due to the seasonal sparcity of entrainment organisms during successive pond fill or pond level maintenance activities a
(November and December 1978, January and March 1979), additional entrainment monitoring has not been conducted.
Impingement
. Impingement monitorine was conducted during each day of pond fill or level maintenance activities. A preliminary assessment of impingement during initial pond fill is reported in Assessment of Impingement During Initial Pumping to the Midland Plant Cooling Pond, (CP Co 1979).
Impingement associated with March 1979 pond level maintenance activities is reported in Aquatic Assessment of the Tittabawassee River in the Vicinity of Midland, Michigan, (LMS 1980). Additional impingement collections will be reported in an impingement and entrainment summary report anticipated by December 15, 1981. The summary report will include a review and evaluation of the complete l
Midland pond impingement and entrainment data base and discuss the importance and potential impact of entrainment and impingement associated with proposed operational intake activities.
SAhITARY WATER Domestic water for the power block and associated facilities will be supplied by the Midland Municipal Water District (Node 25). Domestic water for the visitor / training center and the outage building and sanitary water for Warehouse No 2 will be supplied from wells located adjacent to each structure.
Sanitary wastewater from all sources on the plant site will be transported to Dow for treatment and disposal, except wastewater from Warehouse No 2 which is i
discharged to an adjacent septic tank and drainfield.
PRECIPITATION Precipitation falling on the plant site will be transported via roof drains and site storm drains to Bullock Creek, the Tittabawassee River, and the cooling pond (Nodes 1, 2 and 3 and Figure 3).
Precipitation falling on areas I
where oil contamination may occur such as transformer areas, and oil storage areas (Node 48) is routed to the oily waste collection system.

EXHIBIT III WATER USAGE PROCESS *n'ATER Process water is derived from the Midlana Municipal Water District and from The Dow Chemical Company. Midland city water is used in the makeup demineralizer system, the laundry facility, sanitary, and laboratory fixtures.
l All of the process water used in the process steam system is supplied by Dow l
Chemical.
Dow Condensate Usage Condensate and demineralized water from the DOW Chemical Company are stored in separate tanks near the plant site and adjacent to the condensate return pumphous e.
Water from the demineralized water storage tank is used as makeup
(
for the condensate storage tank. Fumps in the condensate return pumphouse take suction from both the demineralized water and the condensate storage tanks.
Demineralized water is directed through miscellaneous sample panel and monitor coolers prior to discharge to the process steam evaporators.
Condensate (Node 20) is pumped to the evaporators for conversion to steam.
Floor drainage from the condensate return pumphouse is directed via gravity flow to Bullock Creek. Evaporator feedwater is conditioned by the addition of Na 50 '
- 2 4
3 4 (Chemical Node D).
The process steam produced in 0 and Na 0 2 3 the evaporators is then returned to Dow (Node 21) for use in their chemical processes and heating.
Condensate collected from the steam traps on the Dow process steam line will be routed to the site storm drainage system. Blowdown from the evaporators (Node 22) will be pumped to the Dow Chemical Company via the sanitary waste collection system for treatment and discharge or may alternately be routed to the liquid radwaste system for treatment and disposal in the event of unacceptable levels of radioactivity. This blowdown is expected to be continuous.
Midland City Water Usage Midland city water is transferred (Node 23) through the makeup demineralizer system to the plant water storage and transfer system (Node 34). The makeup demineralizers are periodically regenerated by the addition of H SO, and NaOH 2
(Chemical Node F) and the regeneration products are routed (Node 367 to the evaporator building neutralizing sump for treatment and discharge.
The plant water storage and transfer sy; tem consists of condensate storage tanks, a demineralizrJ water storage tank, a utility water storage tank, and a primary water storage tank. Water from the condensate storage tank and demineralized water storage tank is used for makeup in the Units 1 and 2 condensate and feedwater systems (Node 41) and the auxiliary, boilers (Nodes 32 and 33) with the addition of NH3
- "d
(
- i#*1 Intermittent blowdown from the permanen'"t auxiliary boilers (Node 37) and the temporary aigh pressure auxiliary boilers (Node 72) is routed to the oily Amendment 3 miO681 0377d102 III-1 September 30, 1981 l
_____________J
waste collection system. Blowdown from the ermanent auxiliary boilers may begin as early as December 1981 and will c atinue for the life of the Midland Plant. The high pressure auxiliary boiletr will be used for testing and startup between June 1982 and June 1985.
Initial blowdown is scheduled dur2ng May 1982.
Water from the utility water storage tank and the primary water storage tank is used in the Units 1 and 2 reactor plant systems (Node 54) with the addition of H 0 and LiOH (Chemical Node K) and N,H and morpholine (Chemical Node P).
3 3 These tanks will also supply the initial fit,1 for the component cooling water system. Approximately 12.5 lb of N,H and 2 lb of morpholine will be used 4
annually to inhibit corrosion in this system (chemical Node P).
An anticorrosion water chemistry will be maintained in the containment spray system with Na 0 and N,H f 11 wing initial illing rom the Borated Water Storage Tank. 3No annual ~ consumption of these materials is anticipated after 4
4 initial charging of the containment spray system. Small amounts of these corrosion inhibitors may be discharged to nearby floor drains during routine maintenance or repair activities.
Overflow and drainage from the demineralized water storage tank are routed to the river via the site storm drainage system, while overflow and drainage from the condensate storage tanks are routed to the cooling pond via the site storm drainage system. Overflow and drainage from the utility water storage and primary water storage tanks are routed to the Boron Recovery System. The discharge of demineralized water via the makeup demineralizer storage tank overflow / drain line would be extremely infrequent, occu ring only when the water level in the storage tank exceeds normal or when the tank is required to be drained for maintenance. The tank is equipped with a high level alarm and a high level switch which automatically shuts down the makeup demineralizer system. This instrumentation is designed to preclude or prevent overflow occurrences. The storage tank will not be routinely drained for maintenance on any scheduled basis.
It is expected the tank may require maintenance less than once per year. The rated tank capacity is 50,000 gallons of demineralized water.
Midland city water will be distributed throughout the plant to the laundry facility (Node 27), laboratory fixtures (Nodes 28 and 30), and miscellaneous drinking fountains, safety showers, etc.
Domestic wastewater from sanitary fixtures is routed to Dow Chemical via the sanitary waste collection system (Node 24) for treatment and discharge.
Laundry facility wastewater is discharged (Node 52) to the laundry waste treatment system. Drainage from the secondary plant laboratory fixtures in the turbine building will be routed on a continuing basia (Node 35) to the Un.t 2 neutralizing sump for treatment and discharge.
Intermittent sink drainage from the evaporator building laboratory fixtures is routed to the evaporator building neutralizing sump.
Primary and Health Physics laboratory sink drainage is routed to the Liquid Radwaste Sys+em via the Boron Recovery System.
Midland City water will be used for initial fill and subsequent makeup to the plant heating, chilled water and diesel generator cooling water systems. A commercial borate-nitrite additive will be used to inhibit corrosion. The plant heating system will also contain ethylene glycol for freeze protection Amendment 3 miO681-0377d102 III-2 September 30, 1981
and improved heat transfer. Small quantities of these materials may be discharged to nearby floor drains during routine maintenance or repair activities.
NONCONTACT COOLING WATER The cooling pond receivts makeup water from the Tittabawassee River (Node 5) and from precipitation, both directly (Node 4) and indirectly via the site storm drainage system (Nodes 64 and 3).
Water from the river can also be diverted directly to the laundry /radwaste dilution line (Node 6).
The pond provides noncontact cooling water for the Units 1 and 2 condensers (Node 11) and for additional plant cooling requirements via the Units I and 2 service water systems (Node 13).
Plant circulating water is treated with H,SO, (Chemical Node B) and with Na0Cl (Chemicel Node A), is passed through the Units 1 and 2 condensers and is returned to the cooling pond.
In order for the service water system to perform its cooling functions, the service water entering the plant must not exceed its design temperature limit.
The service water cooling tower (Nodes 14-17) will be put into operation as needed to maintain the service water intake temperature below its design limit. Blowdown from the service water cooling tower will be returned to the cooling pond (Nede 18).
Both Na0C1 (Chemical Node C) and H SO4 (Chemical 2
Node N) are injected into the service water system.
Service water (Node 46) is used to generate sodium hypochlorite onsite for use in controlling biological growths on heat transfer surfaces exposed to cooling pond water. Nacl (Chemical Node L) is used in the manufacture of sodium hypochlori te.
Na0C1 will be injected twice daily for a period of one half hour each into the Units 1 and 2 condenser cooling water and service water systems (Chemical Nodes A and C).
Use of sodium hypochlorite will be limited as determined by operation requirements. A chlorine residual as a result of this operation is not expected to persist in the pond for a sufficient timc to circulate to the point from which pond blowdown is withdrawn.
Sulfuric acid will be injected int o the service water and condenser cooling water systems to reduce the formation cf carbonate scale on heat transfer surfaces (Chemical Nodes N and B).
This will slightly increase the sulfate concentration that would otherwise be present in the pond. Some sodium chloride will be present in the effluent produced by the onsite sodium hypochlorite generation system, but this will have negligible effect on the pond sodium and chloride concentrations.
Pond water loss mechanisms include ceepage (Nod' 8), and e'vaporation (Node 9) and intermittent flow to the fire rotection systam (Node 10). Fire c
protection water is ultimately routed via floor drains to the oily waste collection system. The site dewatering system removes groundwater and returns it to the cooling pond (Node 63).
SANITARY WATER USAGE Midland city water is used in sanitary facilities (Node 26) and is discharged to the sanitary waste collection system Well water is used in sanitary Amendment 3 miO681-0377d102 III-3 September 30, 1981
facilities at the Visitor / Training Center, Outage Building and Warehouse No 2.
Sanitary wastewater from the Visitor / Training Center and the Outage Building is discharged to the sanitary waste collection system while a septic tank and drainfield receives sanitary wastewater from Warehouse No 2.
i PLANT DISCHARGES PRIOR TO COMMERCIAL OPERATION Prior to commercial operation, the plant will use well water, City of Midland water and demineralized water for purposes of performing hydrostatic tests and water flushes on various plant systems during construction and testing phases as described below:
1.
Hydrostatic Tests - These tests are used to ensure integrity of welds and connections within a system. This test consists of holding pressurized test water within the system to be tested for given times and pressures.
The water does not become chemically contaminated in any way and present plans call for the discharge of such waters into either the cooling pond or the Tittabawassee River dependent upon the physical location of the hydrostatic testing activities.
(However, no discharge will be made to j
the Tittabawassee without appropriate approvals.)
2.
Flushes a.
Water Flushes - Water flushes differ from hydrostatic tests in that the purpose of the flush is to ensure proper functioning of a system and to remove any obstructions that may somehcw have gotten into a system. These flushes will also utilize well water, City of Midland water or demineralized water.
Large piping is delivered to the plant site with end caps installed.
The only contamination that the flush water could pick up would be minute amounts of rust, dust or oil in the form of thin residual film around pipe ends resulting from pipe beveling or preparation for welding. Minor flushes and hydrostatic tests, performed on components or small systems, will be drained to various building sumps which discharge to the cooling pond.
Two systems are scheduled for flushing as early as November 1981.
Approximately 100,000 gallons and 20,000 gallons of flush water will be routed to the cooling pond from the Condensate Storage and Transfer System and the Demineralized Water Storage and Transfer System Header, respectively.
In April 1982, the condensate system will also be flushed. Other major flushes or hydrostatic tests will be performed on all or parts of the following systems:
feedwater, part of main steam, bleed steam condenser and possibly part of piping to Dow. All major flushes will be drained to the cooling pond. Various stainless steel systems will be flushe' with demineralized water which will also be drained to the cooling pond.
b.
Chemical Flushes - The use of chemical flushes at the Midland site is planned for the condensate and feedwater systems. The chenical flush Amendment 3 miO681-0377d102 III-4 September 30, 1981 V
will be performed by a qualified subcontractor using a single system volume, two step process..The degreasing step will be done using Vertan 662, a corrosion' inhibitor and F082 surfactants at a pH of 4.5.
The iron and millscale removal stage will be completed by raising the system pH with NH 0H followed by an injection of H 0 I# ""#I*C' 4
22 passivation. This method will generate one system volume of chemical waste and one to two system volumes of rinse water waste. All waste will be neutralized prior to discharge to the cooling pond. Table 5 of Exhibit VII indicates the expected chemical characteristics of the wastewater that will be discharged to the pond. This data is based upon the best available information since subcontractor selection is still in progress at this time.
The permanent auxiliary boilers will receive an alkaline boil out as part of system startup. Each boiler will receive one system volume using Trisodium phosphate, Disodium phosphate and a vetting agent and two system volumes of rinse water as early as January 1982. Table 5 of Exhibit VII lists the expected chemical characteristics of the vastewater that will be discharged to the pond.
A subcontractor will also chemically clean eleven low pressure evaparators and two high pressure evaporators on the tube side (seconda ry). The chemicals will be shipped to the site in tank trucks by the subcontractor and removed in tank trucks following chemical cleaning. Eviporator cleaning materials would, therefore, not be discharged into either the pond or the river.
3.
Construction Chemistry Lab Trailer Wastes - Small amounts of waste chemicals resultant from wet chemistry analysis performed in the temporary lab trailer during construction will be discharged to Dow.
Use of the temporary lab trailer is expected to terminate with the completion of the permanent laboratory facilities currently scheduled for early 1982.

EXHIBIT V DESCRIPTION OF WASTE ABATEMENT PRACTICES Selected waste abatement practices improve the quality of wastewater discharged from the Midland Plant. These practices, including separation, pH adjustment, sedimentation, filtration, recirculation, retention, segregation and offsite treatment or disposal, are applied to the waste water streams prior to their discharge to the Tittabawassee River.
PROCESS WATER Oil Separation The oily waste treatment system processes plant floor drainage and precipitation collected from areas which may be contaminated by oil.
Sources of wastewater include:
o Permanent auxiliary beiler blowdown (Node 37).
o Temporary high pressure auxiliary boiler blowdown (Node 72).
o The outdoor transformer area (Node 48).
o Floor drains in the areas of the Units 1 and 2 condensate feedwater and main steam systems, fire protection system and the evaporator building (Nodes 68 and 10).
Oily wastes are collected and transferred to a 300,000 gallon oily waste storage tank by individual pumps located throughout the plant site.
The storage tank combined with oil removal equipment and a waste oil tank treat the collected wastewater to remove oil contamination.
Inside the oily waste storage tanks, underflow and overflow weirs (analogous to an API separator) retain free oil and suspended colids until manually removed to avoid carryover into the tant effluent line. The active capacity (above the overflow weir) is sufficient to retain three inches of rainfall on outdoor collection areas plus the maximum firewater usage event.
If this capacity is exceeded due to an additional simultaneous event, an overflow from the effluent side of the underflow and overtlow weirs is routed to the cooling pond via the storm drainage system.
The oily waste treatment system removes any oil which may not have been retained in the oily waste storage tank (ie, emulsified or dispersed oils).
This remaining oil is separated by physical means in a " package plant" by oil removal equipment. The oil free effluent is discharged directly to the Tittabawassee River while the waste oil is transferred to the waste oil storage tank pending removal from the site by a licensed industrial waste hauler.
Amendment 3 miO681-0377f102-46 V-1 September 30, 1981
pH Adjustment The evaporator building neutralizing sump and the Units 1 and 2 neutralizing sumps receive process wastes and floor drainage from several wastewater sources that are expected to have extreme pH values. Some of these wastewater sources include:
o Evaporator building laboratory fixtures.
o The makeup demineralizer system.
o Chemical addition and storage area floor drains.
1 o Condensate demineralizer regenerative wastes.
o The secondary plant laboratory fixtures.
Air mixers, acid and caustic injection equipment and recirculating pumps located at these neutralizing sumps allow pH adjustment of the wastewater in a batch operation.
Following adjustment to the desired pH, the evaporator building neutralizing sump contents and the Units 1 and 2 neutralizing sump contents are discharged to the Tittabawassee River via the miscellaneous waste and cooling pond blowdown lines (Discharge No 001).
If the effluent from the Units 1 and 2 neutralization sump contains unacceptable levels of radioactivity, the wastewater is diverted to the liquid radwaste system for subsequent treatment.
Sedimentatic.n Wastewater from the Units 1 and 2 clean waste sump and the iron removal sump is discharged to the cooling pond for settling of suspended solids. The clean waste sumps receive condensate polisher backwash and rinse water from the condensate feedwater and main steam systems.
Since this wastewater is very low in total dissolved solids, the effluent from the clean waste sump is routed directly to the cooling pond for disposal. The suspended solids in the effluent (ie, ion exchange resin fines and corrosion products such as iron and copper oxides) are assimilated by the cooling pond sediment.
The magnetic filters remove suspended iron oxides frcm the evaporator condensate before it is returned to the condensate feedwater and main steam systems. These filters require periodic backwashing to remove collected iron oxides. This backwash water is routed through the iron removal sump and into the cooling pond (via the site storm drainage system) where suspended iron oxides are assimilated in tne cooling pond sediment.
If the effluent from the Units 1 and 2 clean waste sump contains unacceptable levels of radioactivity, the wastewater is routed to the liquid radwaste 4
system for subsequent treatment.
If the magnetic filter backwash water contains unacceptable levels of radiaactivity, the backwash will be sent to the liquid radwaste system or the filters will be taken out of service.
Amendment 3 miO681-0377f102-46 V-2 September 30, 1981
Filtration Various articles of protective clothing are cleaned in the laundry facility with non phosphate detergents. Wastewater from this facility is filtered to remove suspended solids in the laundry waste treatment system. Following treatment, the laundry wastewater is discharged to the Tittabawassee River via the miscellaneous waste and cooling pond blowdown lines (Discharge No 001).
If this waste stream contains unacceptable levels of radioactivity the flow is diverted to the liquid radwaste system for subsequent treatment.
Segregation and Treatment or Disposal Offsite Process steam system evaporator blowdown is normally transported offsite and treated by the Dow Chemical Company, Metal cleaning wastes from periodic steam system cleaning and debris removed from both makeup and circulating water intake structures are transported offsite for disposal. The only exception to this procedure involves the evaporator blowdown.
If this waste stream contains unacceptable levels of radioactivity, the flow is diverted to the liquid radwaste system for subsequent treatment.
Radioactive Waste Treatment Radioactive process wastewater and potentially contaminated drainage is collected and treated in the radwaste treatment systems. The major sources of these radioactive or potentially contaminated wastewaters may include:
(1) laundry waste treatment system, (2) reactor systems and solid radwaste system floor drains, (3) Units 1 and 2 neutralization sump, (4) Units 1 and 2 clean waste sump, (5) evaporator blowdown, (6) magnetic filter backwash, (7) effluent from the reactor systems and solid radwaste system and (8) the once through steam generatcrs. Radioactive wastewater treatment involves a combination of filters, ion exchangers, evaporators, and solid waste packaging equipment. Solids removed from the influent liquid radwastes are packaged and transported to a licenced burial site for disposal. The purified water is recycled to the reactor plant systems or discharged to the Tittabawassee River via the miscellaneous waste ar.1 cooling pond blowdown lines (Discharge No 001).
NONCONTACT COOLING WATER Recirculation The 880 acre recirculating cooling pond provides cooling water for the Units 1 and 2 condensers and for various plant cooling requirements via the Units 1 ano 2 service water systems. Condenser cooling water is recirculated to the cooling pond to minimize the discharge of heated effluent to the Tittabawassee River.
Blowdown from the cooling pond is taken from the coolest point in the pond and discharged through three 2-1/2 foot diameter valved pipes. These pipes are oriented perpendicular to the river flow and provide control of the blowdown rate and discharge velocity by valve throttling and. closure. This blowdown control mechanism combined with the recirculation of noncontact cooling water minimizes the release of thermal effluent to the Tittabawassee River (Discharge No 001).
Amendment 3 miO681-0377f102-46 V-3 September 30, 1981
Retention To control biological growth on heat transfer surfaces exposed to cooling pond water, sodium hypochlorite is injected into the Units 1 and 2 condenser cooling water and service water systems. Due to the extensive retention period, a chlorine residual is not expected to persist in the noncontact cooling water effluent for a sufficient time to circulate to the cooling pond blowdown discharge point.
SANITARY WATER Sanitary wastewater is collected from the plant site and transported to the Dow Chemical Company through a sanitary waste pipeline for subsequent treat-ment (Node 24). Approximately 100 to 300 gpd of sanitary wastewater from Warehouse No 2 is discharged to a septic tank and drainfield for treatment and disposal.
OTHER Construction Site Runoff Control In addition to the construction impact control measures specified in the Company's Supplemental Environmental Report and the AEC's Final Environmental Statement, several additional measures are also being implemented for the control of surface runoff. These additional construction impact control measures include:
o Construction of holding ponds in ditches near any source of runoff and near dewatering operations to control siltation.
o Rip-rap applied to Waite and Debolt Drain, Branch #1 Drain and Bullock Creek at changes of grade and at changes of direction to minimize erosion.
o Embankments seeded, fertilized and mulched to control soil erosion.
The construction impact control program follows standard practices presented in the following publications:
o Michigan Soil Erosion and Sedimentation Control Guidebook, prepared for Michigan Department of Natural Resources, et al by Beckett Jackson Raeder, Inc, Februa ry 1975.
o Soil Erosion and Sediment Control: Standards and Specifications for Bay 1 Midland and Saginaw Counties, US Department of Agriculture, Soil Conservation Service, December 1974.

Residuals and Residues Sludges and residues resulting from the treatment or control of wastewaters are contained in the waste oil storage tank, evaporator building neutralizing sump and Unit I and 2 neutralizing sumps. Disposal of waste oil and associated sludges or residues is discussed in this Exhibit under the heading of "ROCESS WATER, OIL SEPARATION. Accumulated sediments incidental to the operation of the evaporator building neutralizing sump and the Unit I and 2 neutralizing sumps are removed on an annual or as needed basis and transported f om the site by a licensed industrial waste hauler.
In addition, accumulated sediments in miscellaneous plant sumps and Unit 1 and 2 clean waste sumps are removed on an annual or as needed basis. Although these residuals do not result from the treatment or control of wastewater, the removed sediments are disposed of in similar fashion as described above.
Residues or residuals generated by the radioactive waste treatment facilities (ie, liquid radwaste and solid radwaste systems) are packaged in accordance with 10 CFR 71 and shipped offsite for ultimate disposal.
If the sediments collected from any of the sumps listed above contain unacceptable levels of radioactivity, these wastes are considered radioactive and processed in a similar fashion as other radioactive wastes.

EXHIBIT VII DESCRIPTION OF EXPECTED WASTEWATER CHARACTERISTICS PROCESS WASTEWATERS The process wastewaters listed below are normally discharged directly to the Tittabawassee River at Discharge No 001, expect for condensate return pump house drainage which is routed to Bullock Creek at Discharge No 002. The expected characteristics of these process wastewaters are presented in Table 1:
o Evaporator Building Neutralizing Sump o Laundry Waste Treatment o Oily Waste Treatment o Auxiliary Boilers (via oily waste treatment) o Liquid Radwaste System I
o Condensate Return Pump House Drainage o Demineralized Water Storage Tank o Units 1 and 2 Neutralizing Sump COOLING POND BLOWDOWN Chemical Characteristics Certain process wastewaters are discharged to the cooling pond on a routine or intermittent basis. Evaporator Building Neutralizing Sump effluent may be discharged to the cooling pond on an optional basis (Sec Process Wastewater above). This wastewater combines in the cooling pond with the Units 1 and 2 condenser cooling water and service water systems discharge (recirculated) and form the cooling pond blowdown effluent. Expected wastewater characteristics of the pond blowdown are described in Table 2.

Thermal Table 3 presents the surface area and length of the 5 F isotherm for various river flows. Physical Model Testing at Alden Research Laboratories was used in deriving Table 3.
River flows used in preparing these temperature distri-butions were based on long range average values. River water temperatures downstream of the mixing zone are not expected to exceed the values given in R323.1075 (2) and (3b) of the Michigan Administrative Code, Part 4, Michigan Water Quality Standards, as a result of the combined Plant discharge (Node 60, Figure 1).
Estimated distances for closure of the 1*F isotherms are given in Table 4.
Appendices A and B provide an overview of the simulation models used as well as the effects of the Plant's thermal plume on the Tittabawassee River.
Appendix A provides a detailed description of the field survey, physical model and mathematical model used in the Plant thermal plume simulation. Appendix B provides a general discussion of the plume in terms of its effects in the near field and far field based on preliminary modeling results.
COMBINED PLANT DISCHARGE WASTEWATER Table 2 of this exhibit presents the expected characteristics of the cooling pond blowdown after being combined with process wastewaters and discharged to the Tittabawassee River as combined Plant Discharge Wastewater. The total dissolved solids concentration in the Tittabawassee River at Freeland Road is not expected to exceed a monthly average of 500 mg/l nor an instantaneous maximum of 750 mg/l as a result of this discharge.
The combined Plant discharge (Node 60, Figure 1) will not exceed the phospho-rus limit of 1 mg/l as set forth in the Rule 323.1060 of the Michigan Administrative Code.
This limit is more stringent than the daily average phosphate limit of 35 lb (exclusive of pond reconcentration of existing levels in the river) that was set forth in the agreement reached between Consumers Power Company and the AEC Regulatory Staff Counsel, Thomas F Englehardt.
CONDENSATE RETURN PU'IPHOUSE DRAINAGE Table 1 of this exhibit presents the expected characteristics of condensate and demineralized water drainage from the condensate return pumphouse. The quality of this water is carefully maintained by DOW to prevent Amendment 3 miO681-0377h102 VII-2 September 30, 1981
cross-contamination from their processes. This high quality water may reach Bullock Creek as a result of incidental leakage or system drainage for maintenance purposes.
PI.AhT DISCHARGES PRIOR TO COMMERCIAL OPERATION Table 5 of this exhibit presents the expected characteristics of preopera-tional wa.=tewater discharges to the cooling pond prior to commercial opera-tion. Also included in this table is a summary of the chemical discharges from the construction chemistry lab trailer to the cooling pond for the period September 5, 1978 through April 20, 1979. As noted in Exhibit III, hydro-static test water will be discharged to either the Tittabawassee River or the cooling pond.
The characteristics of this waste water are also included in Table 5.
The frequency of flush water, hydrostatic test water, and layup discharges is listed in Table 5 as " varies".
This may be construed as several times a week for flush water, approximately once per week for hydrostatic test water, and perhaps a few times each month for system layup discharges. It should be noted that these frequencies are only approximations. Under field conditions, there may be weeks without discharges. As construction progresses towards completion, these discharges may become more frequent.
The cooling pond holds approximately four billion gallons of water when full.
The total estimated discharge of flush water and hydrostatic test water for 1981, 1982 and 1983 is approximately 15 million gallons. To illustrate the effect on pond chemistry, even if the total volume of both these wastewater streams for all three years were discharged all at once to the full pond, the dilution factor would be approximately 270 to 1.
There would be no effect on pond pH.
Pond TDS and TSS would be increased by less then 1 mg/1.
Similarly, the effect on pond chemistry of the other preoperational discharges would be very slight because the dilution becomes much larger as smaller volumes are discharged.
Hydrazine (N H ) rapidly disassociates into water, 34 ammonia and nitrogen gas when exposed to air and, so, can be disregarded.
In addition to the discharge listed in Table 5, there are two small volume discharges associated with the temporary fire protection system. Well leakoff from the temporary firewater pumphouse and seepage from the temporary firewater tank (capacity of 500,000 gallons) drain to Bullock Creek through construction site runoff ditches.
Both of these minor discharges will cease following commercial operation when the temporary fire protection system is eliminated.
Groundwater from the sanitary water well adjacent to Warehouse No 2 is pumped continuously and discharged to a nearby road drainage ditch to prevent pipe freezing during winter months. The road drainage discharges to Bullock Creek.
This discharge will be terminated following commercial operation.

8 APPENDIX A THERMAL PLUME SIMULATION STUDY DESCRIPTION OF FIELD SURVEY STUDY Field surveys of the plume resulting from Dow Chemical Company's tertiary pond effluent into Tittabawassee River were made in the months of July and October of 1977, for a river flow of about 400 and 1100 cfs respectively. The Dow discharge was located about 2000 feet upstream of the Plant river intake structure during the field tests and has subsequently been relocated approximately 200 feet downstream of the Plant river intake structure. The conductivity of the teritary pond effluent was used as a tracer. Data was collected at 5 to 11 cross sections during each survey. The cross sections were spaced approximately 1200 feet apart except in the vicinity of Dow's discharge where a few sections were spaced approximately 150 feet apart, and around bends where sections 600 feet apart were surveyed. The total length of the river reach surveyed was about 12,000 feet and the location of the cross sections is shown in Figure A2.
Measurements consisted of river depth, velocity, and conductivity readings taken in 20 to 30 vertical intervals of each cross section. A Price current meter obtained from the US Geological Survey (USGS) was used for velocity measurements. A top-setting wading rod was used to position the meter during the July surveys when the rivgr.was shallow and a boat, mounted with the necessary measuring equipment 1,
was used during the October surveys.
Standard USGS procedures (6) were followed for the velocity measurements and subsequent discharge calculations.
Conductivity was measured simultaneously with velocity measurements using a Yellow Springs conductivity meter (YSI Model 33).
Conductivities near the water surface and near the river bottom were measured to check the vertical variation of conductivity which was found to be substantially constant with depth, indicating that complete mixing occurred in the vertical direction.
Analysis of the survey data began by plotting the measured river depth, velocity, and conductivity versus transverse distance for each cross section.
Survey results for October 16, 1977 are shown in Figures A3 and A4.
Values of the dimensionless cumulative discharge from the right bank looking downstream were computed and conductivity versus dimensionless discharge profiles were constructed and are shown in Figure AS.
The concentration profiles were developed in this manner so that the stream-tube model described in the mathematical model section of this attachment can be applied.
The conductivity of ambient river was either actually measured or estimated from measured concentration profiles. The ambient value was subtracted from the measured conductivity level so that the " excess conductivity" could be defined and used in the stream-tube model.
The excess conductivity profiles established above were used in the mathematical model as upstream boundary conditions. This required dividing each profile into 10 to 15 segments and determining an equivalent line source for each segment. Additional data consisted of the total river discharge, and estimated value of the constant diffusion factor D for the river reach under consideration, and the distance to the downstream section where a conductivity profile was measured. The D value was then adjusted by making multiple runs Amendment 3 miO681-0377n102 A-1 September 30, 1981
i of the mathematical model until a best fit of computed excess conductivity profile to the measured downstream concentration profile was obtained. The measured downstream profile was then used as the upstream boundary condition for the adjacent downstream reach. By repeating this procedure, D values for each river reach were determined. The constant diffusion factors which yield the best fit to the survey data are given in Table A2.
The transverse
^
diffusion coefficient K,and the dimensionless constant B, both defined in the mathematical section, were computed from D and river flow characteristics and are also listed in Table A2.
The estimated B values vary from 0.2 to 2.7 for the vari.;us reaches for the Tittabawassee River that were studied.
In order to be conservative in modeling the physical effects of the Plant discharge (Reference Attachment B) and in modeling radionuclide transport B value of 0.23 was used.
DESCRIPTION OF THE PHYSICAL MODEL A reach of the Tittabawassee River extending 100 feet upstream to 2000 feet downstream of the river intake structure is simulated in the physical model (Figure A1) at a scale of 1:15. The model topography is constructed on a wood i
frame consisting of templates cut to reproduce the river bottom contours and is covered with plywood to conform tc the topography determined from field surveys. The plywood is sealed with a layer of polyester resin. The detailed features such as the river intake structure and the Dow Chemical Company and Midland Plant discharge outfalls, shown in Figure A1, are also constructed in plywood sealed with a resin coating. The flow field downstream from the Plant discharge structure can be divided into two regions; the near field, and the far field.
In the near field the dilution of effluent with the river is primarily due to jet mixing, dilution in the far field is achieved mainly be transverse convection and turbulent diffusion processes. To model the hydrodynamic mixing in the near field, it is essential to have undistorted geometry and to ensure the equivalence of the Froude numbers in both the prototype and the model. The Reynolds number is not modeled, but it must be i
kept high enough to ensure turbulent flow from the model discharge structure.
Equating the prototype and model Froude numbers yields U
U F =
p
=
F,
=
m (a) p gH gH, where the subscripts p and m denote prototype and model, U ahd H denote a characteristic velocity and depth, respectively and g is the gravitational acceleration. This equality ensures that phenomena influenced by the weight of fluid will be similar in both the model and the prototype.
It is also necessary to equate the densimetric Froude numbers in both the model and the prototype to ensure proper representation of buoyancy effects

where the subscript r density the ration between model and prototype, and ap/p is the initial density difference which depends on both temperature and Total Dissolvcd Solids (TDS) concentration. The selection of a length scale ratio of 1:15 resulted in the scale ratios of Table Al which were calculated from the continuity equation and equations (a) and (b).
Two methods of operation were employed for modeling conveniences; once-through operation and recirculation of the model river flow. For the once-through operation, a constant-head reservoir supplied the flow via a supply line.
Flowrates were measured by a Venturi meter in the line. The flow was then introduced into the model at the upstream trough. Baffles were used to distribute the flow across the entire width of the model river. At the downstream end of the water flowed over a tailgate and was discarded. Air teaperature inside the building housing the model was lowered to a level close to the model river water temperature so that undesirable heat transfer from the air to the model was minimized. For the recirculation operation, water flowed into a sump af ter leaving the model and was pumped back into the supply line. A small amount of water in the sump was replaced by cold fresh water from outside so the model river water temperature could be maintained at a constant level.
The Dow Chemical Company terticry treatment pond discharge was simulated using a hot water boiler connnected in parallel to a saturated brine storage tank.
The relative density of the discharge flow was maintained by controlling the temperature and brine (TDS) concentration in the flow. The discharge flow vas continually monitored with an in-line orifice plate metering section. The Plant discharge was similarly modeled, although its relative density was maintained by adjusting only the water temperature which was achieved with a boiler and a mixing network. The cooling pond makeup water was withdrawn through a geometrically similar structure via a small pump.
The withdrawal flow as well as the discharge flow were monitored by in-line orifice plate metering sections.
Surface and near bottom water velocity measurements were made with a calibrated miniature propeller meter.
Temperature measurements in the mode:
were accomplished using a matrix of about 230 copper /cor.stantan thermocouples.
These probes were used to measure surface and vertical temperature profiles throughout the model, in addition to critical temperatures for model operation such as air temperature, discharge temperatures, and river inflow temperatures.
The ambient river temperature was monitored by three proces located in the upstream flow distribution trough. The thermocouples could be scanned at desired time intervals and the excess temperature (water temperature less ambient river temperature) at various locations could be Amendment 3 miO681-0377n102 A-3 5eptember 30, 1981

and its operation are contained in Reference 1.
DESCRIPTION OF THE MATHEMATICAL MODEL FOR TRANSVERSE MIXING OF SOLUTES IN NATURAL STREAMS Themathematicalmodel(jgbasicallythestreamtubemodeloriginallypropo{gj by Yotsukura and Cobb adopted by the'US Nuclear Regulatory Commission The model was developed for the transverse diffusion of-solutes-from stea'dy sources placed in a natural stream with steady discharge. Density of water is assumed to be homogeneous-throughout the system. Vertical variations of solute concentration, velocity, and diffusion coefficient are neglected through the use of depth averaged values. As a result of these assumptions, the predicted solute plume is two-dimensional. 'The applicability of the stream tube model to the Tittabawassee River was verified by a number of field surveys of a conductivity plume resulted from Dow Chemical Company's tertiary pond effluent into the Tittabawassee River near the Plant. A description of 1
the field surveys has been previously described.
The theoretical development of the model involves the derivation of a diffusion equation by balancing inflow and outflow of solute mass in a control volume. The dependent variable is the solute concentration and the two independent variables are longitudinal distance along the river and transverse.
cumulative discharge, q, from the river bank:
y q = f ud dy (d) o j
where y = transverse distance from river bank u = local river velocity at y
-d = local river depth The use of the cumulative discharge instead of the transverse distance from i
the river bank enables a closed form solution to be found for natural rivers i
with irregular channel cross-sections. Boundary conditions are zero solute concentration gradient at both river banks and a known solute concentration
's profile at the upstream end of the river reach to be studied.
The stream-tube model (2) as originally formulated only applied to situations where the upstream solute concentration profile resembles a point source or a l
constant strength line source perpendicular to the river flow..
To treat variable solute concentration at the upstream boundary, a collection of short constant strength line sources was used to approximate the variable solute concentration profile. The stream-tube model was applied repeat'edly with each short line source as the upstream boundary condition and the iolutions were l
added. The solution obtained by this superposition is valid since the diffusion equation is linear.
The only parameter appearing in the diffusion equation is the' constant
- diffusion factor D.
The evaluation of D requi' es a reparate estimation of the r

THERMAL PLUME EFFECTS Operation of the cooling pond blowdown system forms a thermal plume in the Tittabawassee River.
The thermal plume consists of two parts, the near field and the far field.
In the near field the blowdown discharge dilutes rapidly with river water through a jet mixing process. Further mixing in the far field is mainly due to transverse convection and turbulent ciffusion. The thermal plume is simulated by a physical river model for the near field and by a mathematical model for the far field as described in Attachment A.
Heat loss from the thermal plume into the atmosphere was not considered.
Dow Chemical Company discharges its tertiary pond effluent into the Tittabawassee River at about 300 feet upstream from the Plant blowdown structure. Both discharges are at the south bank of the river and are shown in Figure A1.
The excess temperature (temperature of the effluent less ambient natural river temperature) of Dow's effluent is incorporated into the Plant thermal plume simulation.
Physical model test results (Reference 1) in the near field resulted to the 1 F isotherms shown in Figures B1 to B5.
Io extend those isotherms in the far field, the transverse convection-diffusion mathematical model of Yotsukura and Cobb (Reference 2) was used.
Parameters needed in the mathematical model include river cross-sections and their velocity distribution as well as diffusion factors.
The Tittabawassee River geometry, river flow distribution, and excess i
temperature at the end of the near field (Section A shown in Figure B6) are used to initiate the far field thermal plume mathematical modeling. The l
linkage between near field and far field is based on an excess temperature versus dimensionless cumulative discharge profile at Section A which is used as the upstream boundary condition in the mathematical model.
Diffusion factors for the reach of the river extending from the near field to Section B (shown in Figure B6 at Gordonville Road) have been computed for a range of river discharges based on field data collected during July and October of 1977. Although no detailed field data is available for the reach of the river downstream of Section B, the Corps of Engineers has made a survey at the Smith's Crossing Road bridge which is shown as cross-section No 10 in Figure 2.4.19 of Reference 3.
This cross-section is quite similar to Section B.
The river was also observed on several occasions at the Smith's Crossing and Freeland Road bridges (Sections C and D shown in Figure B7),
approximately 0.5 and 4.5 mile downstream of Section B, respectively. The river cross-sections at those locations resemble that of Section B, having steep banks. slow moving current, and a deep channel. Based on these observations, it was assumed that the Tittabawassee River characteristics downstream of Section B are similar to those of Section B.
The diffusion factor for this part of the river was, therefore, determined from the hydraulic properties measured at Section B.
Amendment 3 miO681-0377p102 B-1 September 30, 1981
After determining the diffusion factor for a river reach and after defining the excess temperature versus cumulative discharge, a profile of excess temperature versus cumulative discharge at the do"ustream end of the reach was computed from the mathematical model. For the next reach downstream, this profile was used as an upstream boundary condition together with a new value of the diffusion factor to compute the excess temperature profile at the downstream end of the reach. By repeating this procedure, the lateral transport of the thermal discharge over a large distance downstrem was evaluated resulting to the lengths of the l'F isotherms listed in Table 4 for each river discharge. The distances should be conservative since the mathematical model does not account for surface heat transfer to the atmosphere. Due to the lack of information on river cross-sectional shapes and "elocity profiles downstream from Section B, isotherms could not be drawn for the far field.

APPENDIX C ANALYSIS OF MIDLAND PLANT COOLING POND OPERATION INTRODUCTION The cooling pond has been designed to adequately dissipate the vaste heat resulting from the generation of approximately 1300 MWe of electricity and four million pounds per hour of steam. The pond will effectively transfer waste heat to the atmosphere through evaporation, back radiation and conduction processes.
The cooling pond makeup and blowdown operation is designed to control the pond Total Dissolved Solids (TDS) concentrations which originate from use of l
Tittabawassee River water. TDS input from the plant operation, circulting water acid and hypochlorite addition and the possible discharge of condensate demineralizer regeneration waste are not significant. As evaporation losses of pond water resulting from the heat dissipation process will result in total dissolved solids accumulation, the cooling pond blowdown and makeup process will allow for TDS control within the pond operating requirements.
A description of the basic regulations, assumptions and data utilized in this analysis follows:
1.
Regulations Discharging cooling pond blowdown into the Tittabawassee River has two primary effects: Creating a thermal plume and adding TDS to the river.
To protect the water quality of the river, the following rules of the Michigan Water Resources Commission (MWRC) must be maintained.
i a.
Heat load to the river shall not warm the receiving water at the edge i
of the mixing zone to temperatures greater than the following monthly maximum temperatures:
Month:
J F
M A
M J
J A
S O
N D
F:
41 40 50 63 76 84 85 85 79 68 55 43 b.
Heat load to the river shall not warm the receiving water at the edge of the mixing zone more than 5 F.
c.
The size of the mixing zone is limited such that it does not contain more than 25% of the cross-sectional area and volume of flow of the river at any river transect.
d.
The controllable addition of TDS to the tiver shall not increase the river TDS concentration beyond 500 ppm as a monthly average nor more than 750 ppm at any time.
Atendment 3 miO681-0377r102 C-1 September 30, 1981
Dow Chemical Company discharges its tertiary pond effluent into the Tittabawassee River about 300 ft upstream from the location of the cooling poad blowdown discharge. Both discharges are at the south bank of the river. Dow's effluent also adds heat and TDS to the river.
2.
Physical Assumptions Simulation of the daily operation and the TDS concentration levels of the cooling pond are based on the following physical assumptions:
a.
Total dissolved solids in the cooling pond come from the Tittabawassee River only. TDS input from plant operation, circulating water acid and hypochlorite addition and the possible discharge of condensate demineralizer regeneration waste, is not significant and is not considered.
b.
Cooling pond volume gain by precipitation is assumed to be equal to the volume loss of seepage. This is a conservative assumption since an annual average precipitation of 30 inches over the pond surface of 880 acres is equivslent to 3 cfs which is larger than the estimated pond seepage loss of 0.5 cfs.
c.
No credit is taken for TDS loss from the cooling pond via seepage.
d.
Pond TDS is uniformly distributed throughout the pond volume.
e.
The effluent of Dow Chemical Company's tertiary pond is assumed to be a continuous discharge having a flowrate of 67 cfs with an excess temperature of 5'F and a TDS concentration of 2500 ppm.
f.
Average daily T;ttabawassee River flows for water years 1937 to 1977 are us=d in the operation study.
(This assumption was utilized for analytical purposes only. River flow may vary widely over a day due to operation of Sanford Dam.
Operating controls will assure continuous compliance with the withdrawal schedule set forth in Exhibit II.)
g.
The assumptions that the cooling pond is full and that pond TDS is at concentration of 500 ppm are used as initial conditions for the a
simulation of the pond operation.
3.
Operation Assumptions In this study, the operation of the cooling pond (timing and amount of makeup and blowdown), is governed by the following assumptions:
The annual refueling period for each unit is assumed to be one month.
a.
Refueling occurs in September for Unit I and in April for Unit 2.
The hegt load to the cooling pond is 3370 x 10" Btu /hr for April, 5680 x 6
10 Btu 'hr for September, and 9050 x 10 Btu /hr for the remaining months of the year.
Amendment 3 miO681-0377r102 C-2 September 30, 1981
b.
Maximum allow nle blowdown flowrates as determined f rom the Alden Research Laboratery (ARL) test program are a function of the river flow and blowdown excess temperature (blowdown temperatore less natural river temperature). Blowdown flowrates used in the pond o;7 ration study were kept below a set of maximum allowable values shown in Figure C-1 derived from the ARL test program and consideratica of thermal constraints in the Tittabavassee River.
Makeup flowrates are kept as high as possible without filling the pond c.
above elevation 627 ft.
The constraints on makeup flowrates are listed in Subsection 3.4 of the Environmental Report. The maximum makeup flow utilized in the pond operation simulation is 270 cfs corresponding to the makeup pumps runout conditions.
I d.
In order to simulate pond operation under the most stringent conditions, Dow effluent discharge into the Tittabawassee River is given priority over the Midland Plant cooling pond blowdown discharge.
The Midland Plant blowdown flow will be controlled so that it will not cause the river TDS to exceed 500 ppm.
l e.
The maximum blowdown flowrate is limited to 220 cfs because of hydraulic characteristics of the gravity fed blowdown scheme. The minimum flowrate is 5 cfs due to difficulty in throttling for flows below 5 cfs.
f.
The pond water surface elevation imposes the following limits on the makeup and blowdown flowrates:
1.
When pond level is above 627 ft, no makeup is permitted and blowdown may be discharged at its maximum allewable flowrate.
2.
When pond level is 626.5 ft, no blowdown it permitted and makeup withdrawal may be made at its maximum allavable flowrate.
3.
When pond level is between 627 ft and 626.75 ft, both makeup withdrawal and blowdown discharge may be made at their m:ximum allowable flowrates.
4.
When pond level is between 626.75 ft and 626.5 ft, makeup flowrate may be set at its maximum allowable value and the blowdown flowrate is limited so that the pond level is nct lowered because of the blowdown discharge.
g.
Fond blowdown discharge is terminated when daily average natural river temperatures are within 5 F of the monthly maximum temperatures.
4 Data a.
The US Geological Survey gaging station on the Tittabawassee River is located some 4700 ft upstream from the Midland Plant
- river intake structure. Daily average river flows published by tne USGS from water years 1937 to 1977 were used in the cooling pond operation simulation.
Amendment 3 miO681-0377r102 C-3 September 30, 1981
b.
Natural river temperatures on a daily average basis from October 1, 1975 to September 30, 1978 as recorded by the Dow Chemical Company at the Dow dam were extracted and used to develop a model relating long term daily natural river temperatures and daily dry bulb temperatures.
From dry bulb temperatures recorded at the Bishop Airport of Flint, Michigan, natural river temperatures were generated from March 3, 1049 to September 30, 1978 and were used in the pond operation simulation.
Daily natural river TDS concentrations were either directly obtained c.
or estimated from the natural river conductivities contained in the monthly Operating Report of Dow Chemical Company from October 1975 to September 1977. Conservatively, the higher 1976 TDS concentrations were used repeatedly in the study.
d.
A transient cooling pond mathematical model was used to estimate daily average blowdown temperatures and pond evaporative losses.
e.
A physical model was utilized to determine the quantity of blowdown that could be discharged into the Tittabawarsee without resulting in a mixing zone more than 1700 feet long and not exceeding the 25'4 cross-sectional limits for the thermal mixing zone.
Both the Dow tertiary pond discharge and the cooling pond blowdown were simulated in the physical model. A matrix of 275 thermocouples, positioned throughout the model, were used to determine the maximum allowable blowdown flowrate for a given blowdown excess temperature and river flow. For all data provided, the edge of the thermal plume is based on the location of the 5 F excess temperature isotherm as determined by the average temperatures obtained from 25 scans of each of the thermocouples.
5.
Simulation of Pond Operation A computer program was written for the daily simulation of the cooling pond operation. For each day, the makeup and blowdown flowrates (if any),
pond volume and pond TDS concentration are calculated from known blowdown excess temperatures (blowdown temperature less natural river temperature) and natural river TDS concentrations. The logic of the program incorporates all assumptions and operation rules previously outlined.
6.
Conclusions The following conclusions resulted from the simulation of the cooling pond operation based on the assumptions presented previously. Pond blowdown will be controlled by measuring the actual river flow, upstream river temperature, excess temperature of blowdown, upstream river TDS and Dow discharge ronditions.
a.
It is feasible to control the pond TDS level by a makeup-blowdown scheme. Based on the available data, the operational assumptions set forth result in pond TDS concentrations that are acceptable for the circulating water and service water system hardware.
Amendment 3 miO681-0377r102 C-4 September 30, 1981
b.
On an average temperature basis, the thermal plume shall not cover more than 25% of cross-sectional area or volume of river flow at any transect of the river, and its length shall not exceed 1700 feet.
c.
On a long term basis, cooling pond blowdown and the resulting thermal plumes will exist in the Tittabawassee River about 27% of the time.
Fifty percent of the time, blowdown is withheld because Dow effluent uses the whole TDS capacity of the river. Eight percent of the time, blowdown cannot be discharged because natural river temperatures are within 5 F of the monthly maximum temperatures set by MWRC. The pond water level was below 626.5 ft 2% of the time and no blowdown was discharged. The calculated blowdown flowrater are below the present minimum blewdown flowrate of 5 cfs 13% of the time, so that no blowdown takes place.
Variations between actual values of the parameters which will control pond blowdown and assumptions used in the study may result in increased frequency and blowdown rates. The combined effects of the cooling pond blowdown and the Dow Chemical Company discharge shall comply with Michigan Water Quality Standards regarding temperatures, TDS, mixing zone length and width.

APPENDIX D ELOVDOWN MD MAKEEP CONTROL SYSTEM An automatic control system is trevided to minimize the TDS concentration in the cooling pond by maximizing bleadown and makeup flowrates. The frequent changes in the s - riables, particularly river flow, d:ctate the need for an automatic rather than a manual system.
The combined effects of the cooling pond blowdown and the Dow Chemical Company discharge shall comply with Michigan Water Quality Standards regarding temperatures, TDS, mixing zone length and width. The cooling pond is generally kept full when possible and therefore blowdown will usually be voluntarily restricted when makeup cannot keep up with pond losses.
ELCbBOWN CONTROL 1.
Elowdown flowrate is determined by calculating the flcwrate tbat sat' fies the TDS requirements an separately calculating the flowrate that satisfies the thermal requirements. The lower of the two flowrates is selected and is then checked to verify that it is within the physical range of the blowdown system.
Pond 1cvel and makeup rate are also checked to make certain that blowing down will not decrease the pond level.
The calculated blowdown rate is then set by an automatic adjustment of the l
three blowdown control valves.
Flow measurement is provided in each blowdown line.
Periodically the flowrate is recalculated and reset as required (every 15 minutes to I hour - to be determined based on o;> retir y experience).
2.
The blowdown flowrate to satisfy thermal requirements is calculated from the Alden Research Laboratory model testing program results. Calculations can be done by interpolation for all river flowrates up to the maximum rate tested.
For higher river flowrates, extapolation of the test data and proportioning are used to calculate blowdown flowrates.
The measured parameters required for this calculation of blowdovn are river flowrate, the cooling pond blowdown temperature and the natural river temperature.
If the natural river temperature approximates the monthly maximums stated in the water quality standards, the blowdown is reduced or terminated, as necessary, to preclude exceeding the monthly ma x i Fium.
3.
The blowdown flowrate to satisfy river TDS requirements is calculated by doing a fully mixed mass balance using measured values of river flow and TDS concent ration, the Dow discharge flow and TDS concentration and the blovdown TD5 concentration.
The allowable TDS river concentrations are 500 ppm as a daily average and 750 ppm as an ins tantaneous n.a:<imum.
A.mendment 3 miO681-0377s102 D-1 September 30, 1981
MAKEUP CONTROL 1.
The measured river flowrate is used to select a makeup flowrate that complies with both the makeup withdrawal schedule and the maximum 1 ft/see velocity in front of the intake structure traveling screens requirement.
2.
The calculated flowrate is established by starting the required number of pumps and adjusting the control valve in the recirculation line to bypass the excess flow Flow measurement is provided to determine both net makeup and bypass.
3.
Makeup is automatically terminated when the pond is full.
RADWASTE DISCHARGE DILUTION 1.
Pond blowdown is used for radwaste dilution when the blowdown flow is
- adequate, i
2.
Radwaste dilution flow from the discharge of the makeup pumps will be used when pond blowdown flow is <45efs.
Pond blowdown will be temporarily suspended when radwaste dilution flow is in operation.

APPEhTIX E ANALYSIS OF THE MIDLAND PLANT THERMAL PLL?!E AND THE DOW CHEMICAL COMPANT DISCHARGE INTERACTION BAC}:GRol3D Or..T u ly 28, 1978, the Michigan DNR staff requested Consumers Power to analyze the possible interaction between critical Inaterials discharged f rom The Dow
'Se.mical Ccmpany and thermal effluent from the Midland Plant. A September 13, 1938 letter from Mr Robert Easch provided a list of critical materials that should be included in the secpe of the analysis. This list originated from Dow's annual wastewater report of critical materials discharged during 1977.
l The resulting analysis was provided in Amendment I to the State Discharge Fermit Application dated October 20, 1978.

w APPENDIX F THERMAL PLUME EFFECT ON DISS0IXED OXYGEN LEVELS Bacxeround Oa July 23, 1976, the MDNR Staff requer.ted Consumcrs Power to assest the effect of the Midland Plant's thermal discharge on dissolved oxygen levels in the Tittabawassee River.
Under certain conditions, the cooling pond discharge could reduce dissolved oxygen levels in the river as a result of the limited solubility ci exygen in heated ' eater and the potentially high biological oxygen demand of the *:idland effluent.
In response to the Staff's request, the company engaged Lawler, Matusky and Skelly Engineers (LMS) to evaluate the impact of Midland Plant discharges on dissolved oxygen levels in the Tittabavassee River. The results of this analysis are reported in LMS (1980) and summarized in the following discussion.
Analysis l
Tc assess the effect of cooling pond discharges on dissolved oxygenslevels in the littabawassee River, a water quality mathematical model was developed.
This neJel was calibrated with the results of an intensive water _ quality study (Gannon 1963), thus allowing the accurate reproduction of dissolved csygen, carbonaceous biochemical oxygen demand and temperature.
The calibrated iodel was used to determine the separate and combined effects of the Midland P2 ant discharge and the "idland Wastewater Treatment Plant vaste loads on dirsolned
. y g e t.
levels in the river. The model included the various Dow Chemical Comva:q withdrawals and discharges. These ef fecte were sin.ulated under a variety of plant and river flow, temperature, and loading conditions.
An analysis of average monthly river and plant flovs and ten peratures determined that the month with the greatest potential dissolved oxygen decrease was April.
Study results for average April conditions are summarized in Table F-1.
The following conclusions arise from the (April) spring m? del results:
1.
The present (and operational) monthly average river DO levels for April are (and will be) significantly higher than the State Wat er Quality Standard requiring a 5.0 mg/l daily average with no single value less than 4.0 mg/l (Rule 323.1064 of the M2chigan Administrative Code).
2.
The influence of organic activities (CEOD) is not expected to cause a significant drop in river DO levelc.
3.
For the average monthly Apria condition, the effect of the M(dland blewdown on DO levels in the river appears to be minimal.
The largest
~
decrease is 0.3 mg/l (from 9.5 to v.0 mg/1).
Average seasonal conditions were also analyzed for impact on river DO levels.
These results are summarized in Table F-2.

APPENDIX G MP10NTATEi> WASTEWATER PROCESSING BACKGROUND During normal operation, the condensate polishers remove various chemical and particulate contaminants from the secondary system condensate.
In additica, the resins pick up ammonia used to control pH levels in the steam cycle. When regenerated, the resins release the accumulated ammonia in the backwash water resulting in up to 1200 mg/l of ammonia. Approximately 16,000 to 53,000 gal-lens of ammoniated wastewater is generated daily by the condensate pel.;shers.
Previous versions of the Midland Plant NPDES Permit Application indicated that the condensate polisher regenerates would be neutralized in the Units 1 and 2 Neutralizing Sump and discharged to the Tittabawassee River. However, the re-sulting wastewater could contain levels of ammonia which may lower the dissolved oxygen concentrations in the river. This, in combination with existing river conditions, may cause the water quality standard for dissolved oxygen to be exceeded.
ANALYSIS The Ccmpany is evaluating several methods aimed at reducing the effects of the ammoniated wastewater discharge. A primary criteria for evaluating these methods is a maximum concentration of 2 mg/l of ammonia in the wastewater discharged to the Tittabawassee River.
The Company is studying ammonia processing methods that would result in a wastewater discharge to either the Tittabawassee River or to the cooling pond.
An engineering evaluation of these systems is nearing completion. An assessment is also underway to determine if the long term routing of condensate polisher regenerates directly to the cooling pond would potentially result in ammonia concentrations in excess of 2 mg/l in the pond blowdown.
CONCLUSIONS The Company is continuing to review various options for the disposal of condensate polisher regeneration vastes. Following completion of these engineering studies, the Company will identify its specific plans for disposal cf the condensate polisher regeneration wastes.

APPENDIX H DETERMINATION OF NATURAL R WER TEMPERATURE In response to a December 13, 1978 Stafi's suggestion, the Company proposed a monitoring program for determining the natural water temperature in the Tittabawassee River, on February 20, 1979. Staff's concurrence on the pro-posal was received on February 28, 1979. The monitoring program was accom-plished es proposed during 1979. However, the dismantling and relocation of the Dow Chemical Company's temperature probe and the determination that the Dow H-flame discharge influenced water temperatures near the Midland Plant, required additional data collection and analyses during 1981 to complete the natural riv-r temperature assessment.
The 1981 program is designed to: provide data describing water temperatures at the relocated Dow monitoring probe, determine the relationship between water temperature at a sampling location above Dow Dam and the Dow probe, de-termine the water temperature relationship between the Midland Plant intake c
and the Dow probe, and determine the effect of the H-flume on water tempera-tures collected at the Dow probe and Plant intake locations. Data will be collected at the 13 locations sampled in the 1979 monitoring effort plus the H-flume outfall, a cooling pond location, and the Dow probe. Data evaluation will include correction factors to adjust current Dcw probe and intake.
temperatures to upriver water temperatures, if applicable. The assessment is tcheduled for completion by December 31, 1981.
