Dear Mr. Stum:

SUBJECT:

APPLICATION FOR TRANSFER OF PERMIT CHANGE OF FACILITY OWNEE HIP NOTIFICATION DREDGING PERMIT NO(7572" THREE MILE ISLAND NUCLEAR STATION (TMINS)

Please find attached four executed copies of the Department's Application for Transfer of Permit form. The completed forms transfer Permit No. 2275724 from GPU Nuclear, Inc. (GPUN) to AmerGen Energy Company, LLC (AmerGen). Thetransfer of compliance responsibilities for the dredging permit was effective December 20, 1999. The effective date corresponds to the date of financial closing forthe purchase of TMI Unit-1 and the TMI Unit-1 support facilities by AmerGen

(,>

from GPUN.

As background information, Permit No. 2275724 was issued to Metropolitan Edison Company on January 13, 1976, by the Department's Division of Dams and Encroachments. Because the subject permit covered routine maintenance of the station's screen intake structures, GPUN requested an extension of thepermit in April 1982. The Department issued an indefinite extension to the permit by letter dated May 21, 1982 (see attached copy of Permit No. 2275724 and the Department's extension letter). A, condition of the permit stated that the permit authorization by the Department was contingent upon the approval and permitting by the U.S.

Army Corps of Engineers (ACOE). The ACOE permit remains in effect for this project and is effective until December 31, 2005. The ACOE Baltimore District Office was provided notification of the facility ownership change and by letter dated January 24, 2000, authorized the transfer of the ACOE permit to AmerGen. The current ACOE dredging authorization is referenced as CENAB-OP-RR (AmerGen Energy Company, LLc) 197500083-4 (see attached copy of ACOE permit transfer authorization and support documentation).

AmerGen will comply with the Department's rules and regulations for dredging activities covered under the referenced dredging permit. However, please be advised that there are several changes to the station operations that should be reflected in the Department's files. First, the TM!

Unit-2 Screen Intake Structure has not been operational for many years.and there is no routine maintenance dredging of the structure. AmerGen's responsibilities under this permit are limited to dredging at the TMI Unit-I Screen Intake Structure only. Secondly, the silt that is hydraulically removed from the TMI Unit-1 Screen Intake Structure Is pumped only to the onsite settling basin identified as the "Suction Dredge Disposal Basin" (see Figures Nos. 1 and 3 of the attached extension letter). The basin labeled as "Mechanical Dredge Disposal Basin" on the figures is not used for the disposal of any dredge spoils. This basin is part of the station Yard Drainage System and cannot be used for spoils disposition. If mechanical dredging of the area outside of the TMI Unit-1 Intake Structure were required, either the "Suction Dredge Disposal Basin" or an alternate upland location would be used for disposal of the dredge material. Discharges from overflow of the "Suction Dredge Disposal Basin" are covered under the station's NPDES permit, and dewatered silt removed from the disposal basin is dispositioned in accordance with the Department's Waste Management Program requirements.

5938-2000-036 Page 2 of 2 Finally, the routine maintenance dredging operations for the TMI Unit-I Screen Intake Structure occur Inside the structure and directly in front of the Screen Intake Structure. The suction dredging is performed by underwater divers and has minimal impact on the river outside of the Intake Structure. Similar to past practices under GPUN, AmerGen understands that routine turbidity monitoring is'not required forthese maintenance activities (see Permit No. 2275724, Conditions for Stream Operations, Item C.). For routine maintenance dredging under the PADEP permit and the ACOE permit, AmerGen Will continue-to provide advance notice. of planned routine maintenance activities as in the past.

Todd, Please delete the e-mail from 03/15/2003 and replace with this e-mail.

There was one minor change made to the Groundwater report for the OSF/NOB Well - Optional reporting.

For the period covering 01/30/02 to 01/06/03 the flow is corrected to 10,700 gallons instead of zero gallons reported on the form submitted yesterday.

Please find attached files for the 2003 Annual Monitoring for TMI Unit 1.

Annual reports are attached for Consumptive Use (Docket No.19950302) and Groundwater Withdrawals (Docket No.

19961102).

INTRODUCTION Purpose The purpose of this manual is to describe the procedures to be used for determining the amount and timing of releases from the water supply storage in the Cowanesque Reservoir.

History In September 1976, the Susquehanna River Basin Commission ("Commission")

adopted Regulation 803.61, requiring that all consumptive water users commencing operations after January 23, 1971, and consuming more than 20,000 gpd provide compensation for or suspend consumptive use whenever the natural flow at the point of taking was less than the 7-day, 10-year low flow (Q7-10) plus the amount of consumptive use (C). The Susquehanna Steam Electric Station (SSES), owned by Pennsylvania Power and Light Company (PP&L), and located near Berwick, Pa., and the Three Mile Island Nuclear Station (TMI), owned by General Public Utilities Corporation (GPU) and located near Middletown, Pa., are subject to that regulation.

The Cowanesque Reservoir is located on the Cowanesque River near Lawrenceville, Pa. The reservoir is owned and operated by the U.S. Army Corps of Engineers. On March 15, 1978, Pennsylvania Power and Light Company requested the right to purchase water supply storage in the Cowanesque Reservoir for the purpose of providing consumptive loss makeup for SSES. Subsequently, General Public Utilities requested the right to purchase water supply storage in the Cowanesque Reservoir for consumptive loss makeup for TMI.

In 1978 the Commission and the two power companies requested that the Corps of Engineers investigate the feasibility of providing water supply storage in Cowanesque Lake for the purpose of providing consumptive loss makeup water for the two power plants. The Corps conducted a feasibility study of reallocation of storage in Cowanesque Reservoir between 1979 and 1982. The study concluded that it was feasible to increase the elevation of the permanent pool at Cowanesque to elevation 1,080 ft., to provide 25,600 acre-feet of storage for water supply purposes. In January 1982, the Commission adopted the Corps recommendation into the SRBC Comprehensive Plan.

In order to meet the requirements of the Susquehanna River Basin Compact, and to address the concerns of the local interests, the Commission conducted a series of Special Studies between 1983 and 1986.

These studies included development of procedures for determining the amount and timing of releases, and the verification of compliance with the consumptive loss makeup regulation.

Subsequent to the completion of the Special Studies, the Commission recommended to the Corps of Engineers that the storage be reallocated, and formally agreed to function as manager of that storage. Contracts between the Commission and Corps of Engineers and between the Commission and the two power companies were signed on June 30, 1986. The contracts provide for 24,335 acre-feet of storage to be allocated to water supply between elevations 1,011 and 1,080 ft. ngvd. The amount of water supply storage was revised to allow for future sedimentation in the reservoir.

Construction of modifications of the Cowanesque Project began in July 1987.

The water supply storage was operational in December 1989, and the water supply pool was filled to elevation 1,080 ft. on April 27, 1990. Construction was complete as of July 1, 1990.

Management Policies The Commission has adopted the resolutions and policies regarding the management of the water supply storage. The following management principles were included in the Main Report of the Cowanesque Lake Water Storage Project Special Studies.

1. The Commission shall require development of 25,600 acre-ft. of water supply storage at the Cowanesque Project. The amount of storage was subsequently changed to 24,335 acre-ft. in the contracts with the Corps of Engineers and the power companies to allow for future reduction of storage due to sediment deposition.

2. The Commission, as manager of the proposed Cowanesque water supply storage, can allocate the water supply storage in ways consistent with the Compact and in conformance with the consumptive loss makeup regulation and these policy statements, and with the minimum release schedule proposed by the Corps of Engineers.

3. For purposes of developing the operations plan, it will be assumed that both units are in operation at both power plants. The subsequent contract with the owners of TMI states that the contract and the obligations of the owners are limited to only one unit at TMI.

GPU has, subsequently, confirmed by correspondence that releases are to be made for only one unit.

4. The operations plan should be designed to minimize, insofar as possible, drawdown of the recreation pool for consumptive loss makeup purposes, consistent with the primary purpose of meeting consumptive loss makeup needs for the two power plants. However, low flow conditions at SSES and/or TMI will periodically require drawdown of the recreation pool to meet 2

consumptive loss makeup needs. Minimum releases made by the Corps of Engineers may also drawdown the recreation pool in some years regardless of the need for consumptive loss makeup.

5. The plan for managing the water supply storage at Cowanesque Reservoir must be flexible, must satisfy these policy statements, should be adopted as part of the Comprehensive Plan, and should be periodically evaluated and modified as necessary.

6. Commission Resolution 82-5, states that, "Each participating party shall recognize the right of the Commission to reallocate the water supply storage in Cowanesque that is under contract to the Commission to higher uses, as required by the public interest following reasonable notice and subject to appropriate compensation...."

7. Commission Resolution 83-8 states that the opportunity for other water supply users to share equitably in the water supply storage acquired in the Cowanesque Project shall be preserved.

These policy principles were modified by Commission Resolution 89-12, which adopted the following release plan.

1. Whenever the natural flow at Wilkes-Barre is less than or equal to Q7. 10+C (868 cfs), a release will be made in the amount of C+25 cfs, or 85 cfs, whichever is greater, for the first three days. If streamflow at Wilkes-Barre is still less than Q7. 10+C, the amount of release will be C+5 cfs, for the duration of the period when flows at Wilkes-Barre are less than Q7.1 0+C.

2. Whenever the natural flow at Harrisburg is less than or equal to Q7_10+C (2,565 cfs), a release will be made in the amount of C+40 cfs, for the first three days. If streamflow at Harrisburg is still less than Q7 _10+C, the amount of release will be C+5 cfs, for the remaining duration of the period when flows at Harrisburg are less than Q7 -10i+C.

3. During periods when surcharge releases are required simultaneously for both locations, the maximum release will be 125 cfs.

These policy principles will be revised, if necessary, based on experience and future needs.

Basic Principles of Management Plan The Commission will determine the timing and magnitude of releases, and will provide appropriate instructions to the Corps of Engineers. The Corps of Engineers will operate the gates in order to provide the requested releases in accordance with established water quality guidelines.

The plan includes the following elements:

1. The criteria for determining when to begin and end releases, and the amount of the release.

2. Procedures for collecting and processing data for the purpose of determining whether to begin and end the release, and the amount of the release.

3. Procedures for coordination with the Corps of Engineers, USGS, PP&L, and GPU.

PROCEDURES FOR MANAGING WATER SUPPLY STORAGE Criteria for Determining When to Make Releases The Q7-10 was computed for the period of record through 1985 and 1986 at Wilkes-Barre and Harrisburg, respectively.

The resulting Q7-10 values are shown in Table 1, along with design values of C, and a triggering flow value. The triggering flow shown in the table is the sum of the Q7-10 and Raystown reservoir releases.

The appropriate trigger level for beginning releases shall be determined by adding the value of the actual consumptive use, C, to the values shown in the column labeled triggering flow in Table 1.

Table 1. Flow Parameters Wilkes-Barre (SSES) 814 54 868 814+C 1,200 Harrisburg (TMI) 2,543 22 2,565 2,663+C 1 3,500 2,943+C 2 1 During period May 15 to November 15 2 During period November 15 to May 15 Releases will be directed by SRBC to replace consumptive water use for the SSES site and/or the TMI site whenever the streamflow at the Wilkes-Barre and/or Harrisburg gage is equal to or less than triggering flow shown in Table 1. The releases shall begin on the day when the instantaneous observed flow first becomes less than the triggering level at the respective gage.

Determination of Reservoir Adjustments Most reservoirs in the basin release flows that are close to inflow during low flow conditions, so that the effect of reservoir operations on river flows is negligible. The major exception is the Raystown Reservoir. The Harrisburg Q7-10 was calculated from 5

about 100 years of record, unadjusted for any reservoir releases including Raystown, which as only been in operation since 1975. There were sufficient low flow events in the Harrisburg record that Raystown's effects are negligible in raising the Harrisburg trigger level. Therefore, adjusting the Harrisburg gage trigger flow for the Raystown release is appropriate.

The Corps of Engineers releases 200 cfs from the Raystown reservoir during the period May 15 to November 15 whenever the inflow is less than 200 cfs and the pool elevation is less than 786 ft ngvd. During the remainder of the year, the release is 480 cfs whenever the inflow is less than 480 cfs and the pool elevation is less than 786 ft ngvd.

The resulting average augmentation is estimated to be 120 cfs during the summer period, and 400 cfs during the winter period. Therefore, the trigger level for making releases from Cowanesque to meet consumptive use makeup needs at Harrisburg will be increased by 120 cfs during the summer period, and 400 cfs during the winter period.

The Sunbury Fabridam, which is located on the Susquehanna River near Sunbury, and is owned and operated by Pennsylvania Department of Environmental Resources, has the potential to have a very significant effect on flows downstream, if the dam is deflated or reinflated during periods when consumptive use makeup releases from Cowanesque are being considered or actually occurring. Pa. DER has been requested to notify the Commission when either condition occurs. These instructions will be further formalized.

Since the change in operation of this dam is expected to affect flows at Harrisburg for only brief periods, a simple procedure for adjusting the observed Harrisburg hydrograph for the effect of these flows is believed to be adequate. In the absence of significant rainfall that affects flows at Harrisburg, the rate of decline of the Harrisburg hydrograph immediately prior to deflation or reinflation can be assumed to continue during the affected period. Observed hydrographs at Sunbury and Harrisburg that show the effect of deflation of the Fabridam during 1988 are shown in figures 1 and 2.

Changes in release rates at other state and federal reservoirs may occur as a result of drawdown to winter pool or for maintenance activities. Procedures for determining the effects of these releases on flows at either target gage will be developed as needed. Such releases may result in modification or suspension of the required consumptive use makeup releases at the discretion of the Commission.

Tracking Flows When observed average daily streamflows at the respective location are less than the tracking flow shown in Table 1, the Commission staff will begin keeping detailed records for that event and stream gage. The detailed record keeping includes: recording the observed average daily strearnflow for the previous day; recording the latest instantaneous observed streamflow; recording consumptive use data from the respective power company; and determining whether the streamflow is less than the triggering level.

Amount of Release The amount of the release will be equal to the consumptive use plus amounts to allow for surcharge flow needed to initially fill the channel and offset transit losses.

For SSES:

For the first 3 days after beginning a release: C+25 cfs; and For the duration of the period: C+5 cfs.

For TMI:

For C+40 cfs for the first 3 days; and For the duration of the period: C+5 cfs.

If surcharge releases are required simultaneously for both locations, the maximum release will be 125 cfs.

Consumptive Use Data Acquisition During the period when streamflows are less than the tracking level flow, the design consumptive use will be used to determine whether the flows are approaching the triggering level flow. When flows approach the triggering level flow shown in Table 1, the power company will be requested to provide the current consumptive use and their best estimate whether the consumptive use will change significantly in the next several days. Consumptive use data will be based on meter readings or calculation methods, as mutually agreed upon by the Commission and the power company.

Streamflow Data Acquisition Observed streamflow data will be obtained from the U.S. Geological Survey (USGS), Pennsylvania District Automatic Data Processing System (ADAPS) computer data base. If the streamflow data is not available in ADAPS, the USGS will be contacted to obtain current readings, either directly from the satellite downlink or from backup sites. If only stage data is available for the previous day, midnight, noon, and midnight stage readings will be used to compute the average daily flow.

Data Analysis Procedures The Commission staff will keep an operations log for each event. The operations log will include stream flow, reservoir release and consumptive use data, and the releases made during the drought period.

COORDINATION In order to carry out the operations of the water supply storage, data will be needed from the two power companies, the Corps of Engineers Baltimore District, and USGS. The key contacts are shown in Table 2.

With the Corps of Engineers, Baltimore District The Commission staff will notify the Corps of Engineers by telephone when the detailed record keeping has commenced or ended. During that period, the Corps will advise the Commission of the level of storage in the Cowanesque Reservoir as of the beginning of the day, and any plans to change releases from Cowanesque Reservoir. The Corps will also advise the Commission staff of any plans to change the releases from any of the reservoirs in the basin that may impact the consumptive use management operations.

The Commission staff will notify the Corps by 3:00 p.m. if there is a need to begin or end a water supply release, or make any change in the magnitude of the release.

The Corps will make the necessary changes in gate settings at their convenience, but not later than midnight of the same day.

The amount of the release will be determined from gate settings and rating curves, and verified by using data for the USGS stream gage on the Cowanesque River at Lawrenceville, which is a short distance downstream from the darn.

The Commission staff will furnish written confirmation of any instructions to the Corps the same day. Only changes will be confirmed in this manner.

The Corps of Engineers will furnish to the Commission staff an accounting of the storage used, including backup computations and data, at a mutually agreed upon interval, and in a mutually agreed upon form, during or following any occurrence of releases from the Commission's storage space.

The Corps will notify the Commission staff immediately if the amount of storage remaining is less than or equal to 10 percent of the total Commission Storage Space.

In accordance with the contract, the Corps will have the sole responsibility for determining the level at which the water will be withdrawn, and controlling the quality of releases.

The Corps will furnish records of the amount of water stored in the Project and the amount allocated to the Commission storage space, as provided in the contract.

With -the Power Companies The Commission staff will notify the respective power company whenever detailed record keeping is started and ended for that plant.

The Commission staff will notify the respective power company by telephone on the same day, or on the first working day following, if there is a change in the amount of the release being made for that plant.

With U.S. Geological Survey Since rating curves change over time, and since the current rating curve may not include low flows, there may be a need for additional flow measurements when flows reach the tracking level.

Procedures for making those flow measurements are incorporated in a contract between the Commission and USGS 13

SRBC INTERNAL OPERATIONS The operational sequence for data processing and decision making is as follows:

I. If streamflows are less than the tracking level flow at either Wilkes-Barre or Harrisburg, retrieve the current strearnflow data for that gage. If either the average daily value for the previous day, or the latest instantaneous value of streamflow is less than the tracking level flow shown in Table 1, begin detailed data collection for that plant and initiate coordination with USGS, Corps of Engineers and the respective power company.

2. The following procedure applies when determining whether to make a consumptive use makeup release for SSES. Retrieve streamflow data for the Wilkes-Barre gage, and determine average daily flow for the previous day.

Determine whether adjustments for operation of other reservoirs are necessary.

If flow is not approaching the triggering level the design, consumptive use (Table 1) may be used. If flow is approaching the triggering level, request consumptive use data from PP&L. Enter average daily flow, latest instantaneous flow, and consumptive use into the operations log.

3. The following procedure applies when determining whether to make a consumptive use makeup release for TMI. Retrieve streamflow data for the Harrisburg gage, and determine average daily flow for the previous day.

Contact the operator of the Sunbury Fabridam to determine whether any changes in operations are planned, if necessary.

Determine whether adjustments for operations of other reservoirs are necessary. If flow is not approaching the triggering level the design, consumptive use (Table 1) may be used. If flow is approaching the triggering level flow, request consumptive use data from GPU. Enter average daily flow, latest instantaneous flow, and consumptive use into the operations log.

4. If the strearnflow is less than or equal to the triggering level flow shown in Table 1 plus the amount of the consumptive use, notify the Corps of Engineers to begin making releases. Notify the appropriate power company that releases have been started. Notification should be by telephone and confirmed by letter. Changes in releases should be handled the same way.

5. If a release has been started, and the flow becomes greater than the triggering level flow, the release should be discontinued. Notify the Corps of Engineers by telephone and confirm with a letter. Notify the respective power company by telephone and confirm with a letter.

6. Detailed record keeping should continue until the flow has become greater than the respective tracking level flow shown in Table 1.

15

The final decision as to whether to begin, change the amount, or end the release will be made by the Chief Engineer or his designee.
