The members of a shoring system that retain the earth in position and are supported by other components of the system (e.g., plywood, plank or other sheeting).
2.14. Shields: A structure that is able to withstand the forces imposed on it by a cave-in and thereby protect employees within the structure. Shields can be permanent structures or can be designed to be portable and moved along as work progresses.
Additionally, shields can be either pre-manufactured or job-built in accordance with 1926.652(c)(3) or (c)(4). Shields used in trenches are usually referred to as "trench boxes" or "trench shields".2.15.

Site Excavation Coordinator:
A position within Exelon Nuclear that coordinates excavation activities during excavation work.2.17. Soil Classification System: A method of categorizing soil and rock deposits in a hierarchy of Stable Rock, Type A, Type B, and Type C, in decreasing order of stability.
The categories are determined based on an analysis of the properties and performance characteristics of the deposits, the characteristics of the deposits, and the environmental conditions of exposure.2.18. Spoil: The dirt, rocks, and other materials removed from an excavation and either temporarily or permanently put aside.2.19. Surcharge
-means an excessive vertical load or weight caused by spoil, overburden, vehicles, equipment, or activities that may affect trench stability.
2.20. Stable Rock: Natural solid mineral material that can be excavated with vertical sides and remain intact while exposed.2.21. Structured Ramp: A ramp built of steel or wood, usually used for vehicle access. Ramps made of soil/rock or are made for personnel access only areconsidered structural ramps. Suitably rated manufactured ramps are acceptable.

Excavation within the tolerance zone requires extra care and precaution (i.e., digging conducted by hand, air suction (vacuum truck), pressurized air, and/or pressurized water).2.23. Trench: A narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth is greater than the width, but the width of a trench (measured at the bottom) is not greater than 15 feet (4.6 m). If forms or other structures are installed or constructed in an excavation so as to reduce the dimension measured from the forms or structure to the side of the excavation to 15 feet or less, the excavation is also considered to be a trench.

SA-AA-1 17 Revision 10&#xfd;Page 44 of 51 ATTACHMENT 5 Available Ground Scan Technologies Page 1 of 7 As described in this attachment, there are five main methods to locate underground utilities:
ground penetrating radar (GPR/GPIR), magnetic, electromagnetic, active line tracing (radio frequency (RF) and audio frequency (AF)), and acoustic pipe tracing.Guidance for selecting the most appropriate method is outlined on pages 1 through 7 of this attachment.
The most suitable location techniques would be GPR, magnetic, active line tracing, and acoustic pipe tracing. Active/acoustic line tracing involves introducing a signal into an identified line and allows the line to be traced. Although electromagnetic technologies provide great depth of penetration, the background EM present at the utilities will interfere with the instrumentation per discussion with ARM Group Inc., an earth resource engineering/consulting firm. It must be noted that the chart provided below provides the maximum depth of penetration based on ideal soil conditions.
If Possible, use a "scan as you -go technique" to monitor the depth of buried utility. It must be noted that these aregeneral characteristics associated with the various technologies.
It is customary to use various technologies during scans to verify the identity of a suspect utility line. Thus, the major factors that affect the accuracy of the scans are the experience level for the surveyors, equipment, and soil conditions.
Prior to use of this equipment, the site excavation coordinator, excavation contractor, ground scan surveyor, and engineeringshould be contacted to determine the feasibility of using this equipment based on the scope and location of the activity.Number Method Pipes Locatable Depth of Penetration Metallic, plastic 1.

SA-AA-1 17 Revision 10 Page 45 of 51 ATTACHMENT 5 Available Ground Scan Technologies Page 2 of 7 1. GPR/GPIR Ground Penetrating Radar (GPR) is a technique that uses high frequency radar waves to image the subsurface. The GPR instrument consists of a recorder and a transmitting and receiving antenna. Different antennas provide different frequencies, which usually vary between 25 and 1,500 MHz. Lower frequencies provide greater depth penetration but lower resolution. However, GPR using 100 MHz is regulated by the FCC and may not be usable at some utilities.
Thetechnique can be used where the overburden (top layer of soil) contains little clay or silt. An unsaturated Overburden will provide the best penetration depths. If these conditions exist, then penetration depths may be a few meters. A 400 MHz antenna is used for fairly shallow applications to depths of about 10 feet. To calculate the depth to the utility, the speed of the GPR 'signal in the soil at the site needs to be obtained.
This can be estimated from charts showing speeds for typical soil types, or it can be obtained in the field by conducting a small traverse across a buried feature whose depth is known. GPiR is a method developed by Witten Technologies which is an advanced GPR method that can produce 3D images of the underground scanned utilities.
Advanta.ges:
The GPR method provides a rapid technique for locating utilities.
Since the data is viewed on a screen on the instrument, the data can be viewed in the field and the locations of anomalies marked on the ground. This method has good discrimination of targets unless they are stacked.
Limitations:
Probably the most limiting factor for GPR surveys is that their success is very site specific occasionally varying 500% within 20 feet, and depends on having a contrast in the dielectric properties of the target compared to the host overburden, along with sufficient depth penetration to reach the target. Penetration depends on the frequency of the antenna, the conductivity of the overburden, and whether clay is present in the overburden.
Signal penetration decreases with increased soil conductivity.
In addition, for lower frequencies, where the antenna is not shielded, reflections can occur from other objects. Generally, this should not be a problem for utility searches since most of the higher frequency antennas are shielded and are the ones used for buried utility surveys. Good to 12-15 ft dependent on soil conditions.
Optimum soils types for GRP penetration are gravels with minimum clay and silt content. Hard rock, ice, and fresh water environs are also well suited to GPR.Pipes locatable:
Metallic, plastic, concrete, transite, terra-cotta.
SA-AA-1 17 Revision 160 Page 46 of 51 K ATTACHMENT 5 Available Ground Scan Technologies Page 3 of 7 Pipes not locatable:
General rule of thumb is 1" for every 1' of depth for location.6" of diameter for each foot over 12'.2, Magnetic To be able to use magnetic methods, the utility must be constructed from, or have included in its construction, some ferromagnetic material.
Ferromagnetic materials become magnetized by the earth's magnetic field, which then produce a secondary magnetic field. The resulting field at the ground surface is a combination of the earth's magnetic field and the secondary field from the utility. This creates an anomaly in the resultant magnetic field that can be detected by the instrument.
Two kinds of magnetic detection instruments are used.
One detects the strength of the magnetic field using one sensor, and the other detects the gradient of the magnetic field using two sensors. Depth of penetration for iron containing materials is typically 5-10 feet.Advantages:
Magnetic locators are simple to operate and provide a field readout or signal when an anomaly is detected.Limitations:
Magnetic locators will only respond to metal that is ferromagnetic.
Metals such as copper, aluminum, and stainless steel are not magnetized by the Earth's field and, therefore, do not produce a magnetic anomaly. The method will also not detect plastic, clay, or concrete pipes. A follow-up investigation using GPR, terrain conductivity, utility-location, and/or excavation methods may be required.Pipes locatable:
Ferromagnetic metals.Pipes not locatable:
Non-ferromagnetic metals: copper, aluminum, and stainless steel. Plastic, clay, and concrete pipe.
SA-AA-1 17 Revision 10 Page 47 of 51 ATTACHMENT 5 Available Ground Scan Technologies Page 4 of 7 3. Electromagnetic (EM)Electromagnetic instruments for detecting utilities produce and sense electromagnetic fields. These instruments will only work if the utility is made from an electrically conductive material.
The instruments produce the electromagnetic fields using a coil through which oscillating current is made to flow, thus producing an oscillating electromagnetic field. Another coil is used to sense this oscillating electromagnetic field. When a coil senses a changing electromagnetic field, a voltage is produced that can be displayed or activate a sound. If a utility is not made from metal, sometimes a metal tracer wire is placed along with the utility, thereby allowing electromagnetic instruments to be used to locate the utility. There are two types of EM instruments used:
conventional and geophysical.
3.a Conventional:
This instrument has several modes of operation and can do both inductive and conductive pipe and cable locating.
It also has a passive mode in which it responds to the electromagnetic fields from 50/60 Hz signals. It provides the ability to directly connect to a metal pipe, thus allowing the pipe to be energized.
In addition, a clamp can be used to connect to a pipe where no direct connection is available.
This clamp then inductively energizes the pipe and allows it to be located.Advantagies:
The instruments are simple to use and provide anomaly indications while the survey is being conducted.
Limitations:
The limitations are generally the depth of the utility, size of the utility (amount of metal), proximity to other local surface or buried metal, and local-power line noise. Generally, these instruments are not significantly influenced by power line noise unless the power line is very close. Passive mode has a 6' maximum effective locating depth.3.b Geophysical:
Two instruments are commonly used by geophysical companies for utility location:
EM-31 and EM-61.Pipes locatable:
Metallic or with metallic reinforcement.
Pipes not locatable:
Non-metallic.
SA-AA-1 17 Revision 10C Page 48 of 51 ATTACHMENT 5 Available Ground Scan Technologies Page 5 of 7 EM-31: This instrument uses two coils, one of which transmits electromagnetic energy at about 9.8 kHz, and the other coil receives the resulting signal.
The coils are located at the ends of the boom. Because the instrument uses oscillating electromagnetic fields, this instrument is said to operate in the frequency domain.The EM-31 can be used to locate buried pipes. It is particularly effective when a long pipe is to be located, since it produces a large response when a length of buried pipe extends on either side of the instrument. The instrument can be used in various modes. Its boom can be held parallel to the direction of travel or perpendicular.
It can be used in a normal operating orientation (vertical dipole mode) or turned 90 degrees about its long axis (horizontal dipole mode). The EM-31 has a maximum depth of penetration of about 20 feet. The depth at which it can.detect a metal pipe will depend on the conductivity of the soil, local electromagnetic interference, and the amount of metal that the pipe contains.
Thus, the diameter and wall thickness of the pipe each influence the data.Advantages:
The EM-31 is simple to use and provides a readout on the instrument allowing field evaluations of the anomalies.
This instrument will generally find metal utilities to depths up to about 10 feet.Limitations:
Probably the largest limitation is that the electromagnetic fields generated by the instrument produce secondary fields, not only in utilities, but also in any other local metal objects, which then radiate their own field that is also detected by the instrument. The instrument is quite long and may be difficult to use in spatially restrictive areas. Furthermore, background EM may cause inaccurate readings rendering the information as unreliable.
EM-61: The EM-61 transmits pulses of electromagnetic energy, rather than a continuous frequency as with the EM-31. Two square-shaped coils are used. The lower coil transmits the electromagnetic energy, and both the lower and upper coils receive the resulting signals. In general, this instrument is not as proficient at detecting pipes as is the EM-31.Advantages:
The EM-61 is an excellent instrument for locating metal in the top 6 feet of the ground surface.Limitations:
As with the EM-31, the instrument produces electromagnetic fields and can energize local metal. However, this is a much less serious problem with this instrument than with the EM-31. Because of its size, the EM-61 may be difficult to use in confined areas. If that is the case, the hand-held EM-61 can be used. Furthermore, background EM may cause inaccurate readings rendering the information as unreliable.
Depth estimation accuracy +/- 15% under ideal conditions.
Poor discrimination of multiple targets and backfill effects if contains metallic objects.
SA-AA-1 17 Revision 10 Page 49 of 51 ATTACHMENT 5 Available Ground Scan Technologies Page 6 of 7 4. Active Line Tracing This method uses radio frequency (RF) and audio frequency (AF) for tracing cables.Radio Frequency (RF) -Used for tracing cables and water and gas distribution lines since the high frequency signal can jump insulators and rubber gaskets often found in these systems. It is advantageous for inductive locating since the RF travels easily through the ground. In addition, the flood-like quality of the RF signal will induce a signal onto conductors 8 to 10 feet on either side of the transmitter..The instrument's design minimizes electrical interference.
Audio Frequency (AF) -Also used for tracing cables and water and gas distribution lines; however, the low frequency signal does not bleed off a conductor as easily as RF signals. This technique works well in conductive mode and is much more effective in discriminating signals from other nearby conductors.
Advantages:
Good for inductive location since RF travels easily through theground and good for blind searches.
AF does not bleed off a conductor as easily as RF signals. Good up to 10 feet.Limitations:
Poor tracing in dry or high iron content soils.5. Acoustic Pipe Tracing An identifiable acoustic signal is introduced into the pipe via a RF transmitting sound. The receiver detects the sound waves that radiate from the pipe. An acoustic driver is used to put the signal into the pipe, and the sound is detected by sensors attached to a portable receiver and is used to trace and map the pipes.
Depth of penetration is around 4-5 ft.Pipes locatable:
Non-metallic, poor conducting metallic, or cast-iron.

State PA County Dauphin Municipality Londonderry Township b. You must attach a copy of a USGS 7 1/2 Minute Quadrangle map indicating location of proposed intake(s), all existing project sources, and any water storage facilities.
: 3. Purpose of proposed withdrawal(s):
The purpose of the withdrawal is to supply cooling water for operation of Three Mile Island Generating Station, Unit I (TMI-1). A full project description is included in Appendix 2 of the Application.
Provide method of computation for the safe yield estimates of all sources of water supply or submit copies of flow or pumping test data. (See Application Sections 4 and 8.) For all run-of-stream sources and sources with limited storage, compute 7-day, 10-year low flow (Q7-10) using low flow statistical data and appropriate hydrologic engineering techniques.
Whenever an intake is located on an ungaged stream, the applicant must use an acceptable method for computing the safe yield or Q7- 10, such as selecting a reference U.S. Geological Survey gaging station and proportioning the yield based on drainage area.
The selectedgaging station must be on a watershed having similar geologic and climatic characteristics to those of the ungaged watershed.
Other factors to consider are relative size of drainage areas and whether the reference gaging station is influenced by upstream reservoirs or other flow regulation activities.
Up-to-date low flow data for specific gaged watersheds may be obtained from the U.S. Geological Survey district offices. Actual flow data collected at the project intake may be used to supplement the use of a reference gaging station. Any data provided should indicate the method used to measure the flow (current meter, weir, etc.), the dates of observation and the flow observed.
In application Section 6, show calculation for determining the quantity of withdrawal requested for present and future use (over the next 25 years).

TMI-1 operation was initiated prior to November 11. 1995. TMI-1 is now seeking renewal of its NRC operatine license, which, if granted, would extend its period of operation until April 2034. Possible operational changes during the period of extended operation may require increased surface water withdrawals by >100,000 gallons per day. based on a 30-day average. The requested withdrawal quantity will be sufficient for operation including possible changes that may be approved by the NRC during the period of extended operation. The Susquehanna River has been the surface water withdrawal source since TMI-1 commenced operation in 1974. Ground water is used for other purposes.
but is not available in sufficient quantity to be a viable alternative source of supply for cooling system usage. The river is in immediate proximity to TMI-1 and can yield the requested withdrawal amounts.

'j APPENDICES Appendix 1 Project Location and Description Project Description
 
===Background===
Exelon Generation Company, LLC ("Exelon Generation")
owns Unit 1 of Three Mile Island Generating Station ("TMI-I" or "facility").
The Susquehanna River Basin Commission
("SRBC") approved consumptive water use' for electric power generation at TMI- 1 of up to 18 million gallons per day ("MGD"), on a 30-day average.In a separate action, the SRBC approved groundwater withdrawals' from Wells A, B, and C for industrial use at TMI-I in the amount of 0.225 MGD (30-day average).Surface water withdrawals at TMI-1 were initiated prior to November 11, 1995 (when surface water withdrawals became subject to SRBC regulation) and have been in"grandfathered" status.Purpose of Application This Application is to request SRBC approval of water withdrawals and consumptive water use to accommodate TMI-1 water needs for possible future operations, as follows: 1. Maximum daily/maximum 30-day average consumptive water use of 19.2 MGD;2. Addition of the Operations Support Facility/North Office Building Well ("OSF" Well) to the wells currently serving TMI-1 for industrial use (i.e., Wells A, B, and C)with no increase in the currently approved withdrawal of 0.225 MGD, based on a 30-day average; and 3. Maximum daily/maximum 30-day average surface water withdrawal of 122.8 MGD.Identification of Project SponsorExelon Generation Company, LLC ("Exelon Generation"), the Project Sponsor, is a limited liability company organized under the laws of the Commonwealth of Pennsylvania with its headquarters and principal place of business in Kennett Square,Pennsylvania. Exelon Generation owns and controls a generation portfolio composed of a diverse mix of fossil, hydroelectric, nuclear, and renewable facilities.
TMI-1 is one of Exelon Generation's ten nuclear facilities.
3 Mr. Christopher M. Crane is Chief Operating Officer of Exelon Generation.
SRBC Decision dated March 9, 1995, on Application 19950302.2 SRBC Decision dated January 14, 1999, on Application 19961102 (Revised) 3 In January 2009. Exelon Generation officially integrated the nuclear generation assets held by itsAmerGen Energy Company LLC subsidiary into Exelon Nuclear and dissolved the AmerGen legal entity.
TMI-1 was one of those assets.
With regard to this Application, Mr.
Tom Dougherty, the TMI-l Plant Manager, is authorized to act on behalf of the Project Sponsor.Exelon Generation is one of three principal business units 4 of Exelon Corporation, a registered public utility holding company and a publicly traded corporation, organized under the laws of the Commonwealth of Pennsylvania with its headquarters and principal place of business in Chicago, Illinois.
Mr. John Rowe is the Chairman and Chief Executive Officer of Exelon Corporation.
Exelon Nuclear, one of three principal divisions 5 of Exelon Generation, operates the nuclear fleet, including TMI-1. Exelon Nuclear is headquartered in Warrenville, Illinois, and operates the largest nuclear fleet in the U.S. with 17 reactors at 10 stations, representing approximately 20 percent of the U.S. nuclear industry's power capacity, and about three percent of all U.S. power generation.
Mr. Charles Pardee is the President and Chief Nuclear Officer of Exelon Nuclear. TMI- l's Site Vice President is Mr. William Noll.Description of Project and Site TMI-1 is located at 40' 9' 13.75" N, 760 43' 24.12" W on Three Mile Island, a 370-acre island situated in the Susquehanna River. A topographic map is attached after this project description (Attachment Figure 1). The island is located in Londonderry Township, Dauphin County, Pennsylvania, about 10 miles southeast of the state capitol at Harrisburg.
At this location, Dauphin County is bordered by York County at the west shore of the Susquehanna River and Lancaster County just below the southern tip of Three Mile Island. TMI-1 employs over 500 full-time personnel.
TMI- I is a base load nuclear generating facility 6 currently licensed by the NRC to operate at a thermal power level of 2,568 megawatts (MWt).. TMI-1 uses a pressurized waterreactor ("PWR")
in its nuclear steam supply system. The PWR core generates heat, and pressurized-water in the primary coolant loop carries the heat to two steam generators.
Inside the steam generators, heat from the primary coolant loop vaporizes the water in a secondary loop producing steam. The steam line directs the steam to the main turbine causing it to turn the turbine generator, which produces electricity.
The unused steam is 4 The other two divisions of Exelon Corporation are Commonwealth Edison Company and PECO Energy Company.5 The other two divisions of Exelon Generation are Exelon Power (operates the fossil, hydroelectric, and renewable fleet) and Exelon Power Team (markets Exelon's generated electric power).6 Unit 2 of Three Mile Island Generating Station
("TMI-2"), situated next to TMI-1, had been part of theoriginal facility, but has been shut down since the March 28, 1979 accident.
TMI-2 is now owned byFirstEnergy Corporation and is no longer licensed to operate. TMI-2 is in a safe storage mode called Post-Defueling Monitored Storage. The only TMI-2 systems, structures or components that are relied upon for the operation of TMI-I are the Station Blackout Diesel Generator Building and the TMI-2 FuelHandling Building.
2 exhausted to the condenser where it is condensed into water using circulated cooling water. The resulting condensate water is pumped out of the condenser with a series ofpumps, reheated, and pumped back as feedwater to the steam generators.
Water Withdrawal, Use, and Outflow at TMI-1A flow chart is attached (Attachment 2), which depicts the flow of surface and ground water through the TMI-1 and reflects the uses and quantities that are the subject of this Application.
Surface water is supplied from the Susquehanna River to TMI- 1 via an excavated intake channel leading to a cooling water intake structure ("CWIS"). The surface water is used for: " Makeup water to TMI-I's cooling system to replace consumptive and non-consumptive losses;* Non-contact service cooling water for normal and emergency component cooling; and" Wash and sluice water to maintain the trash rakes and traveling screens located inthe CWIS in a clean condition.
Ground water is supplied to TMI-1 from three production wells (Wells A, B, and C) and the OSF Well for use in: " Industrial applications, including demineralized water production, pump lubrication and seal water, industrial coolers, and chemical addition; and" Fire protection service.The OSF well additionally may supply potable water.
A fifth well (the "48S Well") is used solely for drinking water. Therefore, its output is not considered in this Application.
TMI-I's consumptive use of surface water is primarily due to natural-draft cooling towerevaporation, plus a relatively small amount of in-stream evaporation from the heated cooling tower blowdown. Consumptive use of ground water is due to evaporation during industrial cooler and spent fuel pool operation. Other consumptive uses of ground water (e.g., filter cake disposal, steam leakage) are de minimis.Outflows of surface water and ground water from the facility are returned to the Susquehanna River through National Pollutant Discharge Elimination System ("NPDES")
permitted outfalls.Detailed descriptions of the water systems follow.
3 Surface Water Withdrawal and Use TMI-1 withdraws water for consumptive and non-consumptive cooling needs from the Susquehanna River via an excavated intake channel that conveys water into the TMI-1 CWIS 7 on the western shore of Three Mile Island.Surface Water Withdrawal The CWIS provides a continuous supply of water from the Susquehanna River to support TMI-1 operation. The front face of the CWIS, where the water enters from the intake channel, is oriented parallel to the Three Mile Island's western shoreline. The water enters the CWIS under a skimmer wall through two openings into the three intake bays.The skimmer wall prevents floating objects from entering the intake bays when the riveris at or above normal flow. Also, fixed bar grid panels with 24-inch spacing cover the intake bay openings to exclude very large objects.From the intake bay, the water passes through bar rakes with parallel vertical bars spaced 1-inch apart to exclude coarse objects and materials.
Each bar rake is equipped with an automated (traveling) trash rake to remove debris. After coarse screening, the intakewater passes through vertical traveling screens with 3/8-inch square mesh openings, which remove small objects and fine materials.
A water spray system is used to maintain the bar screens and traveling screens in a clean condition.
The bar rakes and traveling screens normally operate automatically, but can be operated manually from a local control panel. In the normal (automatic) mode of operation, the barrakes and screens start periodically, actuated either by high differential water levelbetween the upstream and downstream sides of the bars and screens or a timer.Also, during automatic operation, a screen wash pump starts to supply wash water to the traveling screens and bar rakes. The bar rakes, traveling screens, and screen wash pump stop when the differential level reaches a set low value or the timer times out signifying that a clean condition has been restored.Debris from the traveling screens and bar rakes is sluiced to a trash pit on the south side of the CWIS, from which the debris is hauled away periodically for off-site landfill disposal.In cross section, the CWIS has two levels, the wetted lower level and the operating deck on the upper level. The operating deck houses the drive mechanisms for the screens and pumps and supporting equipment (electrical switchgear, control panels, etc.).7 Originally, a second CWIS, which shared the intake channel, was used to supply TMI-2. This CWIS was deactivated in 1993, following the placement of the TMI-2 nuclear reactor into Post-Defueling Monitored Storage. At that time, all equipment in the second CWIS was removed. All pump motors, piping, and equipment were removed down to the floor level, all power and switchgear were removed from the building, and all underground piping (greater than 8-inches) was plugged.
As a result, there is currently no flow into and through the second CWIS.4 The invert of the intake channel is at an elevation
("El") of 264.5' above Mean Sea Level ("AMSL") and the bottom floor of the CWIS is slightly higher at El 265.0' AMSL.
The floor of the operating deck is at El 308.0' AMSL, above the high water level of the river.The structure occupies the water column from the river surface down to the bottom floor level. The normal water surface level is at approximately 278.0' AMSL, providing an approximately 13-foot depth of water in the intake fore bay and bar and screen area.
The extreme low water surface mark is at approximately 271.0' AMSL. The CWIS is designed to operate in the unlikely event that the downstream York Haven Dam is lost.The screened water flows from the three intake bays into a common pump suction bay, which serves as a sump ("wetwell")
for a total of sixteen (16) installed vertical intake pumps. The floor elevation in the wetwell is at 262.5' AMSL, which is 2.5 feet lower than the floor of the intake bays, to provide sufficient water depth for proper intake pump operation.
The intake pumps are used for nuclear services, secondary services, reactordecay heat removal, reactor building emergency cooling, screen wash and sluice water, fire emergencies, and intake structure ventilation.
A table of existing and projected surface water withdrawal quantities for each system is attached (Attachment 3). The projected total maximum daily/maximum 30-day average withdrawal of surface water, during possible TMI- I future operations is 122.8 MGD.Surface Water Use TMI-I is a base-load generating facility that normally operates year-round to produce electrical power, except for scheduled outages (approximately once every two years for several weeks duration) for refueling and planned maintenance activities.
In general, the surface water withdrawal system operates to support electrical generation with minorseasonal changes.
Consumptive Use of Surface Water TMI-I's consumptive use of surface water is associated with the operation of the circulating water system. This includes natural-draft cooling tower evaporation and in-stream evaporation resulting from cooling tower blowdown.TMI-1 uses a closed-cycle recirculating cooling system to condense the steam in the condenser.
The circulating water system for TMI-1 consists of the following majorcomponents: six (6) circulating water pumps, two natural-draft cooling towers, and a main condenser. During plant operation, circulating water is pumped continuously by the circulating water pumps through pipelines in a loop between cooling towers and the condenser. The design recirculating flow rate is 430,000 gpm. The cooling water absorbs heat in the condenser and releases the majority of the heat to the atmosphere via the towers through the process of evaporation.
The cooled water flows from the towers back to the pumps and is re-used to condense steam in the condenser.
During plant operation, water is continuously bled from the circulating water system backto the Susquehanna River as blowdown in order to maintain circulating water chemistry within acceptable limits and avoid excessive concentration of solids in the water.
For 5 TMI-I's closed cycle cooling system, which uses a fresh water source (i.e., the Susquehanna River) for makeup, the ratio of total dissolved solids ("TDS") in the recirculating water to the TDS in the makeup water ("cycles of concentration")
is normally within a range of about 3 to 6. Approximately 0.5 to 1.2 percent of the total circulating water is let off continually as blowdown to control the solids build-up and tominimize scale formation in the system.
The temperature of the blowdown is normally higher than the ambient stream temperature in the Susquehanna River. The blowdown stream mixes with the river water in a "mixing zone" in which the two temperatures equalize.
The warmer blowdown rises to the water surface while mixing, which causes the rate of evaporation to be higher than from unheated river water surface areas.
This in-stream evaporative loss of surface water is additional to loss via the cooling towers.
Non-Consumptive Use of Surface Water The TMI-1 River Water System supplies water from the CWIS for non-consumptive cooling of heat exchangers and coolers in several normal and emergency service water systems including secondary services, nuclear services, reactor decay heat removal, and reactor building emergency cooling. Other non-consumptive applications include cooling of ventilation equipment inside the CWIS, and automatic wash water for the traveling screens, and wash water for the bar and traveling screen sluice canals.Strainers with 1/8-inch mesh openings are installed on the discharges of the river pumps to protect downstream components. The strainers are continually backwashed by a portion (about 2 percent) of typical river pump flow.Makeup to the natural-draft cooling tower basins to replace evaporative and blowdown losses (described above) is supplied from the outlet headers of the secondary service heat exchangers.
Most of the river water that passes through the secondary services coolers is re-used as cooling tower makeup, and the balance is mixed with the cooling tower blowdown.
In addition to a portion of the water that passes through the secondary service coolers, all the river water that passes through the nuclear services coolers is mixed with the cooling tower blowdown.
The mixture of the secondary services river water, nuclear services river water, and cooling tower blowdown water (plus, when used, the discharges from the decay heat removal river water system and reactor building emergency cooling river water system) is discharged to the Susquehanna River through a permitted outfall.Ground Water Withdrawal and Use Ground Water Withdrawal Ground water for industrial use is supplied from three production wells (A, B, and C) and the OSF Well. The projected withdrawal of ground water from these four wells will not exceed the existing approved amount of 225,000 gallons per day ("gpd") during possible future TMI-1 operations.
When the demand for ground water can be fully supplied from the A, B, and C wells, the OSF well will be used for potable applications.
6 Ground Water Use As stated earlier, TMI- I uses ground water for industrial applications including demineralized water production, pump lubrication and seal water, industrial coolers, and chemical addition.
Ground water is also supplied as makeup to the fire service system and for potable water applications at TMI-1.Consumptive Use of Ground Water The consumptive use of ground water is associated with evaporation from the industrial coolers and the spent fuel pool.Non-Consumptive Use of Ground Water Non-consumptive discharges from these systems are directed, after treatment as required, to the Susquehanna River through permitted outfalls.Summary of Consumptive Use of Surface Water and Ground Water The consumptive use of surface water is associated with cooling tower evaporation and in-stream evaporation.
Exelon Generation utilizes methodologies for estimating these consumptive losses as described in previous correspondence with the SRBC'. The consumptive use of ground water is associated with industrial cooler evaporation and spent fuel pool evaporation.
A table of existing and projected consumptive use quantities is attached (Attachment 4). The projected total maximum daily/maximum 30-day average consumptive use of surface water and ground water during possible future TMIoperations is 19.2 MGD (rounded).
Outflows Surface water and ground water non-consumptive outflows are discharged from TMI- 1 in accordance with its NPDES Permit No. PA0009920.

Air Quality Evaluation
-Equipment or processes that emit air pollutants must be considered in the permitting Of existing operations, the design of new processes, and-changes in existing operations that alter air emissions.
For example, temporary generators are needed on site for the proposed activity, they must be addressed through the appropriate State Permitting Sections (35 lAC 201.142 and 201.152; NJAC 7:27 Subchapter 22; 25 PA Code 127.1).2. Cultural, Historical or Paleontological Resource Evaluation
-Soils on all ExelonNuclear property areas described in the UFSARs for NRC.licensed generating stations have been previously surveyed for Cultural, Historical or Paleontological Resources as part of the licensing process and are considered to be previouslydisturbed. Therefore, new surveys are normally not required for excavations in these areas. REVIEW as applicable, the FES-OL and supplements, FES-CP, Environmental Reports to the NRC and supplements, NUREG-1437 and applicable supplements, and/or Appendix B to the Operating License to obtain information pertaining to the cultural, historical or paleontological significance of the location.where ground will be disturbed. (CM-1)2.1. If the document review indicates the excavation site has not been previously evaluated by the NRC, then CONTACT Environmental personnel to arrange for a survey to determine impacts per SA-AA-1 17. The State Historic Preservation Office may be consulted for guidance on how to proceed.2.2. If the document review indicates the NRC has previously evaluated the location where ground will be disturbed as not significant, then no further action is needed.2.3. If Cultural, Historical or Paleontological Resources are inadvertently discovered during excavation, then REFER to SA-AA-117.
Work will be stopped, and Environmental personnel will coordinate the salvage or disposition of the Cultural, Historic or Paleontological resources.
The State Historic Preservation Office may be consulted for guidance on how to proceed. Work shall not resume until the salvage or disposition of the resources is complete, and Environmental personnel authorize work to resume.3. Asbestos Survey -Each employer who has a workplace or work operation shall ensure that a "competent person" conducts an exposure assessment immediately before or at the initiation of the operation to ascertain expected asbestos exposures during that operation.
The assessment must be completed in time to provide information necessary to assure that all control systems planned are appropriate for that operation and will work properly (29 CFR 1926.1101).
EN-AA-103-0001 Revision 5 Page 24 of 33 ATTACHMENT 4 Environmental Basis Page 2 of 7 4. Aquatic Ecology and Endangered Species Evaluation
-The U.S. Army Corps of Engineers (ACOE), U.S. Fish and Wildlife Service, Illinois Environmental Protection Agency (IEPA), New Jersey Department of Environmental Protection (NJDEP), Pennsylvania Department of Environmental Protection (PADEP) or county conservation district may determine that a proposed earth-disturbing activity will adversely impact an endangered or threatened species or critical habitat. The likelihood of such species or habitats occurring in the affected area should be determined prior to commencing the land disturbance.
Agencies or county conservation districts shall be consulted on ways to avoid or prevent impacts to any species or habitats identified.
If impacts cannot be avoided or prevented, a demonstration on how the impacts will be minimized shall be prepared according to State and Federal laws pertaining to the protection of threatened or endangered species and their habitat (16 USC Chapter 35; 25 PA Code 102.6; 520 ILCS 10).Effects on threatened or endangered aquatic species must be considered prior to disturbing riparian sediments or increasing water withdrawals above previously evaluated levels. Ocean plants, such as Oyster Creek, should review their current National Marine Fisheries Service (NMFS) Endangered Species Act, Section 7, Consultation Biological Opinion.5. Clean Water Act Certification
-For activities involving Federal licenses or permits, including but not limited to construction or operations that may result in discharges to navigable waters, the State or interstate water pollution control agency having jurisdiction over the navigable waters in which the discharge originates or will originate, must certify to the Federal licensing or permitting agency that the discharge will comply with the applicable provisions of sections 301, 302, 303, 306, and 307 of the Clean Water Act, as amended (33 U.S.C. ss/1251 et seq.). This may be done through the issuance or revision of an NPDES permit. In cases where NPDES permits or permit revisions are not needed, a Section 401 Certification may be needed. The State water pollution control agency should be consulted to determine if Clean Water Act certification is needed.6. Clean Water Act Section 404 Evaluation
-Under 33 U.S.C. 401, et seq., the ACOE issues permits to prevent unauthorized obstruction or alteration of navigable waters of the United States. The most frequently exercised authority is contained in Section 10 (33 403), which covers construction, excavation, or deposition of materials in, over, or under such waters, or any work that would affect the course, location, condition, or capacity of those waters. The authority is granted to the Secretary of the Army. Other permit authorities in the Act are Section 9 for dams and dikes, Section 13 for refuse disposal, and Section 14 for temporary occupation of works built by the United States.
7.7.1.7.1.1.!i712 7.2.7.3.8.EN-AA-103-0001 Revision 5 Page 25 of 33 ATTACHMENT 4 Environmental Basis Page 3 of 7 I Erosion Control -Land disturbance activities shall be conducted to prevent accelerated erosion and the resulting sedimentation (40 CFR 122.26;NJAC 7:7A-2.2; or 25 PA Code 102).Erosion and Sedimentation Control (ESC) Plans and/or stormwater permits (Section 4.13) may be required prior to disturbing the following acreages: Illinois -40 CFR 122.26 is incorporated by reference (35 IAC 301.442).New Jersey -ESC plan approval is required in New Jersey if an earthmoving activity disturbs more than 5,000 square feet of the surface area for the accommodation of construction for which the State Uniform Construction Code requires a construction permit. Proposed activities impacting waters of NJ (wetlands, rivers, streams, and lakes) or the shorelines must obtain water obstruction or encroachment permits (NJAC 7:7A-2.2).
Pennsylvania
-An ESC plan is required for any activity that results in a total earth disturbance of 5,000 square feet. A permit must be obtained prior to commencing earthmoving activities disturbing over 5 acres (25 PA Code. 102). Proposed activities, which disturb five or more acres, must obtain an NPDES permit for storm water discharges associated with construction activities.
Proposed activities that change, expand or diminish the course, current or cross section of a watercourse,floodway, or body of water must obtain water obstruction and encroachment permits (25 PA Code 105). The ESC Plan must be approved by the County Conservation District.A copy of the ESC Plan must be available for inspection at the site of the land disturbance.
The primary objective of the plan is to have methods in place to control runoff and water discharges to prevent accelerated erosion and sedimentation in any nearby water body. A Professional Engineer must certify the ESC plan.Local construction permits may also be required for construction activities.
ESCPlan approval from the local conservation district, county, township, or municipality may be a requirement to obtaining construction permits.
Notification to local authorities may also be required prior to construction activities.
Flood Plain Determination
-Areas that have been identified by the FederalEmergency Management Agency (FEMA) as being subject to inundation by a 100-year flood are flood hazard areas. Areas subject to inundation by a 1 00-year flood are identified in flood insurance studies and on maps provided by FEMA. No person may construct, modify, remove, destroy, or abandon a highway obstruction or an obstruction in a floodplain without first applying for and obtaining a written permit from the Department (25 PA Code 106.11).
EN-AA-103-0001 Revision 5 Page 26 of 33 ATTACHMENT 4 Environmental Basis Page 4 of 7 9. Hazardous Material Handling and Storage -HazMat Pre-incident Plans, Spill Prevention, Control and Countermeasure Plans, Risk Management Plans, and Stormwater Pollution Prevention Plans may specify hazardous material handling and storage areas. Proposed changes to hazardous material handling and storage should be evaluated against these plans to determine if plan revisions are necessary.
: 10. Impingement and Entrainment
-The USEPA has finalized the rule implementing Section 316(b) of the Clean Water Act for existing cooling water intakes on lakes, rivers, estuaries, and oceans. The rule for existing cooling water intakes imposes performance standards requiring that plant operations reduce fish impingement mortality by 80 to 95 percent and entrainment of fish eggs and larvae in the cooling water system by 60 to 90 percent. Changes in the characteristics of water withdrawals from waters of the Nation (e.g. increasing the intake velocity, changing structural components of the intake, etc.) must be evaluated for potential permitting issues related to the 316(b) implementation rule and NRC notification per the Facility Operating License, Appendix B, Environmental Protection Plan / Environmental Technical Specifications (Except Dresden).11. National Pollutant Discharge Elimination System (NPDES) Point Source Review -The NPDES program requires permits for the discharge of "pollutants" from any "point source" into "waters of the United States." The terms "pollutant", "point source" and"waters of the United States" are defined in 40 CFR 122.2 (35 IAC 309.102; NJAC 7:14A-2.4; 25 PA Code 92.2(b)).
Activities which involve an increase of existing pollutants in process effluents or the introduction of new pollutants to process effluents must be evaluated for potential permitting and NRC notification per the Facility Operating License, Appendix B, Environmental Protection Plan / Environmental Technical Specifications (Except Dresden).12. Polychlorinated Biphenyl (PCB) Management
-The use, storage, marking, remediation, transportation and disposal of material or equipment containing PCB or contaminated with PCB is regulated by the Toxic Substances Control Act (15 USC 2601) and 40 CFR 761. An evaluation should be conducted to determine if the proposed activity will involve the relocation or removal of any material or equipment containing PCB or contaminated with PCB. Transformers, capacitors and other electrical equipment with dielectric fluid may contain PCB. Florescent light ballasts may contain PCB in the potting material.
In the past, PCB were also used in ceiling tile coatings, and certain painted surfaces, hydraulic fluids, lubricants, heat transfer fluids, and insecticides.
Material manufactured prior to July 2, 1979 may contain PCB. Material manufactured after July 2, 1979 may also contain PCB if it was exposed to PCB or retrofilled with a PCB-containing substance.
EN-AA-103-0001 Revision 5 Page 27 of 33 ATTACHMENT 4 Environmental Basis Page 5.of 7 13. Resource Conservation Recovery Act (RCRA) Review -An evaluation should be conducted to determine if the proposed activity will result in the generation of regulated wastes not listed on the Form 8700-12 Notification of Regulated Waste Activity for the Facility, the notification for conditional exemption for the storage and treatment of mixed waste, and the notification for conditional exemption for the transportation and disposal of mixed waste. Additionally, the Part A Interim Status application, the Interim Status Waste Analysis Plan; the Hazardous Waste Contingency Plan, and the Part A Interim Status Closure Plan may need to be amended, as applicable (40 CFR 262 and 264). If the type of regulated waste activity changes at the facility, a revised Form 8700-12 shall be submitted to the USEPA and affected plans and applications shall be updated.14. Safe Drinking Water Act Review- The Safe Drinking Water Act (42 USC s/s 300f et seq.) was established to protect, the quality of drinking water. The Act focuses on all surface water or underground water sources, actually or potentially designed for drinking use. For Facilities that supply drinking water, compliance with the Act includes complying with well-head protection standards, monitoring drinking water purity and meeting primary (health-related) standards.
States may also require attainment of nuisance-related secondary standards.
Activities that require opening the drinking water system for connection, maintenance, or inspection are subject to disinfection to maintain drinking water purity.15. Significant Environmental Aspects (SEA) -Proposed activities that affect processes contributing to or controlling SEA must be evaluated for potentially unacceptable impacts on the SEA. Unacceptable impacts may be in the form of missed objectives and targets, delays or disruptions in improvement plan implementation, reduced effectiveness of control or monitoring equipment, or elevated risk as scored using EN-AC-101-1, Exelon Environmental Aspects and Impacts Assessment.
: 16. Storage Tank Review -Registration, notification or permitting may be required to install, remove or change the contents of storage tanks. Underground storage tanks require special consideration because of cathodic protection and leak detection systems that are mandated by regulation.
Storage tank review shall also include the piping systems associated with the tank(s).17. Stormwater Drainage Review and Quality Assessment
-General Storm Water permits are required for any construction activity including clearing, grading, and excavation operations that result in the disturbance of more than one acre of total land area. Construction activity also includes the disturbance of less than one acreof total land area that is a part of a larger common plan of development or sale if the larger common plan will ultimately disturb more than one but less than five acres or more (40 CFR 122.26(c)). Permits must be received before qualifying land disturbances can commence.
EN-AA-103-0001 Revision 5 Page 28 of 33 ATTACHMENT 4 Environmental Basis Page 6 of 7 17.1. A stormwater assessment should be conducted if any activity involves modification or extension of stormwater drainage systems, including pipes, open channels, and storage basins. These changes, in addition to changes in chemical handling and storage, should be evaluated with respect to the Facility Stormwater Pollution Prevention Plan.18. Stream Encroachment Determination
-Proposed activities that place an encroachment or obstruction within a stream channel encroachment line shall have permits as required.
Activities that require permits when conducted within encroachment lines include the removal or deposition of material, any alteration of the land or watercourse, construction of structures, filling, dredging, clearing, grubbing, grading, piping, culverting, channelizing, diverting, damming, dewatering,and any other activity that temporarily or permanently alters the character of the floodplain or watercourse.
Additionally, major repair of structures that existed before the stream channel encroachment lines were established may also require a permit (17 IAC 3706.720; NJAC 7:13.4; 25 PA Code 105).19. Superfund Amendments Reauthorization Act (SARA) Title III Evaluation
-SARA Title Ill, also known as the Emergency Planning and Community Right-to-Know Act (EPCRA), creates a cooperative effort among government, business, and the public to disclose potential hazards and develop prevention and preparation plans to manage chemical emergencies.
SARA Title III requires facilities that manufacture, process, or store certain hazardous or toxic chemicals above established thresholds to annually report the presence of these chemicals to state and local governments and to report any accidental releases on a timely basis (40 CFR 312).19.1. A SARA Title III evaluation shall determine if the proposed configuration change or construction activity will include the storage or use of hazardous chemicals at the Facility in amounts above the established reporting thresholds that apply to: 19.1.1. Hazardous substances, or hazardous chemicals in quantities equal to or greater than 10,000 pounds, and/or19.1.2. Extremely hazardous substances in quantities equal to or greater than 500 pounds, or the threshold planning quantity, whichever is less.19.2. If hazardous chemicals will be stored in quantities equal to or above the threshold planning quantities, the facility should organize, analyze and disseminate the resulting information on hazardous chemicals to local governments and the public using the SARA Tier II forms.
EN-AA-103-0001 Revision 5 Page 29 of 33 ATTACHMENT 4 Environmental Basis Page 7 of 7 20. Unreviewed Environmental Conditions
-Where applicable, Environmental Protection Plans / Environmental Technical Specifications (Except Dresden)(Operating License, Appendix B) establish the total environmental information collected and evaluated for the purpose of obtaining permits, obtaining a NRCoperating license, and complying with environmental regulations as the Environmental Basis for the Station (Figures 2, 3, and 4). Changes in Station design or operation or the performance of tests or experiments not enveloped by the bounds of the Environmental Basis for the Station constitute Unreviewed Environmental Conditions that must be evaluated prior to the initiation of the change in Station design or operation or the performance of the test or experiment.
: 21. Waste Handling and Disposal Evaluation -If the proposed work package or configuration change will increase the short term or long term quantity of waste generated (other than normal refuse), or result in the generation of waste not previously stored or disposed, an evaluation of the waste shall be made for container compatibility and appropriate staging location.
Approvals shall also be secured from acceptable disposal outlets prior to shipment off site.22. Wetlands Delineation
-A review of the area affected by the proposed activities is needed to determine if any streams, wetlands, or environmentally sensitive areas are located on or immediately adjacent to the affected area.
