Ml 49201-8643 May 13, 1999 Michigan Department of Environmental Quality 21EPIO.l Surface Water Quality Division, GLEAS 21EP10.l.3 Attn: Mr Jeff Cooper 300 S Washington Street Knapps Centre Lansing, MI 48933 Michigan Department of Environmental Quality Surface Water Quality Division, Permits Section Attn: Mr Barry Burns 300 S. Washington Street Knapps Centre Lansing, MI 48933 CONSUMERS ENERGY COMPANY, PALISADES NUCLEAR PLANT NPDES PERMIT NO. MI0001457 REVISED DILUTION WATER INCREASE - PROPOSED MODIFICATION:

As part of the Palisades Plant's March 30, 1998 NPDES permit renewal application, the Company requested to increase the plant's dilution water flow to generate electricity more efficiently and remain competitive under future electric utility deregulation. The March 30, 1998 request was to increase cooling water withdrawal from Lake Michigan from 68,000 gpm to 138,000 gpm.

The MDNR and MDEQ raised concerns about allowing the increased water withdrawal for reasons of increased impingement of forage fish species, _and whether the thermal loading limit (BTU/hr) would still be met. After further design evaluations by the Plant, it was determined that the initial flow .

increase request could be reduced from 138,000 gpm to 103,000 gpm to better accommodate existing systems and still yield an improved generation efficiency. Therefore, the requested discharge flow increase to Outfall 001 to Lake Michigan is not needed, and we anticipate to maintain the t~ermal loading to Lake Michigan at 2100 x 10 6 Btu/hr. This change in flow and further information regarding the cooling water intake design, operation and impact were discussed with MDNR Fisheries Division on April 2, 1999, and the updated information is included with this revision as Attachment 1.

The purpose of this revision is to modify the requested (3/30/98) flow changes and to respond to the MDNR &MDEQ concerns by:

1. More clearly describing the cooling water intake system, 00599-40.JAC

• 2

2. Providing the background of changes in operati~n of the cooling water system and impacts,

3. Providing the rationale for the current request to increase cooling water fl ow,

4. Providing the data and basis to show expected continued compliance with the existing heat load limitation, and

5. Provide a resolution strategy that will accommodate permitting of the

• requested flow increase and evaluation of monitoring or other mitigative actions.

Permit Application Enclosed as Attachment 2 are marked-up copies of the 3/30/98 permit application pages that are changed as a result of today's proposed dilution water increase modification. These pages report intake, Outfalls OOA, 008, OOF, and 001 flow information. The changes made on the internal outfall pages for Outfalls OOA, 008 and OOF were revised to show more accurate flow rates and are not a necessarily a reflection of the proposed modification.

The plant's flow diagram, Exhibit I-11 has been revised to reflect the proposed modification.

Please replace the plant's 3/30/98 permit application pages with the enclosed copies accordingly. The remaining pages of the 3/30/98 plant permit application are still valid. The renewed NPDES permit for the Palisades Nuclear Plant should be based on the revised information provided in today's packet along with the remaining (unrevised) pages of the 3/30/98 permit application.

SCHEDULE We are available to meet with the Department at your earliest convenience to discuss any subject in the packet or the proposed permit in general. We are looking forward to working with the Department in order that the renewed Palisades Plant NPDES permit is practical yet remains environmentally protective.

If you have any questions on the impingement or thermal subjects please do not hesitate to contact me at (517) 788-1285 or Jenny Crawford at (517) 788-1469.

ATTACHMENT l

1. PALISADES NUCLEAR PLANT COOLING WATER INTAKE SYSTEM Cooling water for. the Palisades Plant is withdrawn from Lake Michigan through an intake crib, located 3300 f~t offshore at about the 35-foot water depth (Figure 1 & 2).

The crib is a 57 feet wide, 57 feet long, 12 feet high box with a steel plate for its top and 2-inch vertical bars spaced 10 inches apart around the sides. Water flows horizontally between the vertical bars. The once-through circulating water flow was designed at approximately 400,000 gpm, discharging after condenser cooling, directly at the shoreline. The intake water velocities at the face of the crib structure ranged from 0.69 to 0.95 fps during once-through cooling operation, and were reduced to <0.1 fps with the conversion to cooling tower operation.

2. PALISADES COOLING WATER SYSTEl\il CHANGES AND Il\IPACTS The Palisades Nuclear Plant began operation in 1971 as a once through cooling facility with a cooling water intake and discharge flow of 400,000 gpm. The changes in cooling water flow and BTU loading are depicted in Figure 3 and briefly summarized below.

1971-1974: Once-through cooling operation intake flow: 400;000 gpm/. 7 to 1.0 fps intake velocities BTU/hr: 6222 x l Q6 Average thennal plume size 231 acres Fish Impingement 653,890 fish (Jan-72 to Oct-73) (Table 1) 1975-1978: Cooling tower operation Intake flow 78,000 gpm/ < .1 fps intake velocity BTU/hr - 1140 x 1Q6 Fish impingement: 7, 189 fish (90 % alewife & slimy sculpin) 1979-1984 Modified cooling tower operation to reduce dilution water flow, and reroute cooling tower blowdown for increased electrical output.

_ Intal<e_ flow: 58, 000 gpm -- ---

• BTU/hr: 1140 x 1G6 from velocity of < .1 fps Alden Lab thermal plume model of modification to meet the 72 acre, 3 ° F above ambient mixing zone criteria 1981 Camp Dresser & McKee Thennal Discharge study demonstrated that thermal plumes were well within the 72 acre, 3° above ambient

• 2 requirement. (The study showed that thermal plumes were < 3 acres at one meter depth).

1985 Discharge flow modifications were made to more accurately reflect flow volumes maximum cooling tower blowdown.

Intake flow 58,000 gpm; flow velocity of +/- .1 fps BTU: 1300 x 106 1988-1999 Modified cooling tower operation to allow for hot-side blowdown directly to the mixing basin. This increased generation by 2-3

. megawatts and also increased BTU/hr from 1300 x 1Q6 to 2100 x 1Q6 Intake flow: 68,000 gpm, flow velocity of +/- .1 fps BTU/hr: 2100 x 106 Thermal plume was within the 72 acre, 3°F above ambient requirement of 2.5 to 3.5 megawatts Estimated plume size of approximately 4 acres at 146% maximum heat release rate (Table 2).

Proposed 1999 Modified cooling tower operation by increasing dilution water flow for increased electrical generation efficiency of 2.5 to 3.5 megawatts.

Intake flow: 103,000 gpm; increased flow velocity to an estimated

+/- .25 fps BTU/hr: 2100 x 106 Thermal plume within 72 acre, 3°F ambient as predicted from past thermal plume study and model.

3. RATIONALE FOR COOLING WATER FLOW INCREASE Under current operation of the plant withdraws from Lake Michigan approximately 68,000 gpm, comprised of 50,000 gpm far dilution water and 18,000 for service water (Figure 4). The associated discharge flow volume is 58,700 gpm at Outfall 001, or 84.5 MGD. The proposed modification (Figure 5) is to increase the dilution volume to 85,000 gpm (maximum), for a total withdrawal rate of 103,000 gpm. Under this operation, the Company estimates that the authorized discharge flow volume of 135.2 MGD at Outfall 001 can be maintained, therefore we are not requesting an increase in discharge for 001.

The concern raised by the MDNR regarding the requested intake flow increase is that without a change in intake dimensions, the intake velocity must be increased. Under those conditions, the rate of impingement will increase, perhaps geometrically, and the

• 3 Department objects to any further loss of fish, especially forage species at the Palisades Plant.

The Company believes that the requested flow increase will result in only a very marginal increase in impingement, or be similar to the level of impingement observed in 1976 (7, 189).

The reasons for this are:

- The intake was designed for a once-through cooling water flow of 400,000 gpm, and the conversion to a cooling tower system substantially reduced the intake flow down to 78,000 gpm for make-up (Figure 3). The combined reduction of intake flow volume and velocity decreased fish impingement from approximately 654,000 to 7 ,200 per year,

- With the larger surface area of the intake for a once-through design, the requested flow increase to a rate of 103,000 gpm is only anticipated to increase flow velocity at the crib face from about 0.1 to 0.25 fps,

- As shown in Figure 3, the requested intake flow of 103,000 gpm represents only a 25,000 gpm increase above the 1975 cooling tower flow rate of 78,000 gpm.

Thus, the Palisades cooling water intake design, coupled with cooling tower operation can safely accommodate the requested flow increase with very minimal adverse impact to the Lake Michigan fisheries.

• Accordingly, the location, design, construction, and capacity of the Palisades Nuclear Plant intake system, still reflects the best technology available for minimizing adverse environmental impact in accordance with Section 316(b) of PL 92-500.

4. HEAT ADDITION Lll\flT DISCUSSION Currently, the NPDES permit for the Palisades Plant allows for two types of condenser cooling operation: one as a closed cooling system, and the other under hotside blowdown conditions. The hotside blowdown condition allows the plant (upon demand) the flexibility to cool down the condenser cooling water by about 1°F by blowing down approximately 58,700 gpm of the wanner side condenser water into the cooling tower basin and discharged through Outfall 001 to Lake Michigan. This operation is in compliance with the current heat rate limit of 2100xl06 BTU/hr, and Outfall 001 authorized discharge volume discharge of 135.2 MGD.

Under the proposed operation, the amount of blowdown to the mixing basin will be increased and still be within the authorized discharge volume of 135 .2 MGD at Outfall 001. The additional cooling water and evaporation from the cooling towers will allow the plant to continue to meet the 2100xH1 BTU/hr limit during all but

• 4 during some months under worst case conditions. The BTU calculation results were derived based on a flow if 127.7 MGD at Outfall 001. The flow takes into consideration cooling tower evaporation and less than maximum pump capacities.

The expected heat release rates to Lake Michigan under the proposed operation are shown by month in the attached Table 3. The estimated worst case heat release rates to Lake Michigan under the proposed operation are also shown by month in Table 3. Due to plant outages, operational data from 1997 and 1998 were used to calculate the expected and worst case scenarios for each month. Under the expected conditions, we anticipate being able to continue operating within the 2100Xl06 BTU/hr limit. Under worst case conditions, exceedances are anticipated during cold water months. In these cases, service water flows can be reduced to maintain compliance with the BTU limit. Monitoring will continue as required in

• the permit to demonstrate compliance.

S. PROPOSAL FOR COOLING WATER INTAKE PERMITTING AND RESOLUTION To demonstrate the continued acceptability of the Palisades Nuclear Plant intake the Company proposes to conduct a one year impingement study in consultation with and approved by MDNR and MDEQ.

At our April 2, 1991 meeting with MDNR Fisheries Division (Mr. Bill Gruhn) we discussed the potential option of installing further fish protection to redU:.ce the fish loss in lieu of a study of impingement. At this time, we are not aware of a fish protection modification for this intake that would be cost effective for the estimated amount of impingement. At the conclusions of the one year impingement study, the Company will review the results with MDNR/MDEQ to determine whether the Palisades intake continues to reflect best technology available for minimizing adverse environment impact.
