1.0 DESCRIPTION

1.1 Structures. Systems or Components Description

Monitoring Wells will be installed in the vicinity of the IP2-FSB, IP2 Transformer YardArea, Condenser Tube Withdrawal Pit, IP2-TB Loading Bay and east side of theDischarge Canal, near the IP3 Security Command Post. The monitoring wells willprovide Entergy the ability to monitor groundwater and evaluate the following:

1.1.1 The source area concentrations of contaminants and the hydrogeology of thebedrock aquifer in the vicinity of the IP2-FSB.

1.1.2 The width of the potential plume, which may emanate from the IP2-FSB andwhich may be detected in existing Monitoring Well No. MW-I 11.

1.1.3 If contaminants may have entered the backfill around the Discharge Canal-

1.1.4 If contaminants may have migrated west of the Discharge Canal

1.1.5 If contaminants may have migrated along the backfill of the Discharge Canaltowards the Hudson River.

1.2 Reason For Chance

As part of the IPEC Dry Cask Storage Project, a new single failure proof Gantry Cranewill be installed within the IP2 Fuel Storage Building (IP2-FSB) to transfer the HoltmcInternational HI-TRAC to/from the 1P2 Spent Fuel Pool (IP2-SFP). In order to facilitateinstallation of the North Pedestal Structure and the Steel Ballast Box Foundation, whichwill support the Gantry Crane, the existing IP2-FSB Truck Bay Floor, EL 80'-O" wasremoved from service. In addition, the sub-floor bedrock and soil, which is adjacent tothe south wall of the IP2-SFP, was excavated to -EL 51 '-0". During recent excavationactivities, two hairline shrinkage cracks in the south wall of the IP2-SFP were exposed,which exhibited signs of moisture. One crack, which is located at -EL 61'-O" near thenorthwest corner of the excavated Truck Bay Area, was observed to be activelydischarging water at a rate of -1.5 Liters/Day. Radiochemistry testing indicatedconstituents found in the discharged water to be generally consistent with water typicallyassociated with the IP2-SFP. This adverse condition is documented in Condition RepcortNo. CR-IP2-2005-03557. Currently, there are no available methods to monitorgroundwater in the vicinity of the IP2-FSB. As a result, IPEC cannot evaluate the sourceand extent of the potential leak from the IP2-SFP. In addition, IPEC cannot evaluate thehydrogeology in the vicinity of the IP2-FSB.

MONITORING WELL DEVELOPMENT PLAN

1.0 Miltilevel Sampling Equipment

The Installer shall use a Waterloo Systems Multilevel Sampling System supplied by Solist. This systemuses modular components which form a sealed casing string of various casing lengths, packers, ports, abase plug and a surface manifold. This configuration allows accurate placement of ports at precisemonitoring zones. Monitoring tubes attached to the stem of each port individually connect thatmonitoring zone to the surface. The standard system is built on 2"0 Schedule 80'PVC pipe to fit 3"- 4' ...

diameter boreholes adiiuses 3 FT long packers. Stainless steel components, custom packer materialsand sizes, Teflon® tubing are available.

Monitoring ports are constructed from 316 Stainless Steel. Ports are isolated by packers at each desiredmonitoring zone and are individually connected to the surface manifold with narrow diameter tubing.This formation water enters the port, passes into the stem, up into the monitoring tube attached to thestem, to its static level. A sampling pump and pressure transducer will be dedicated to each monitoringzorne by attachment to the port stem.

The manifold completes the system at surface. It organizes, identifies, and coordinates the tubes and/orcables from each monitoring zone. The manifold allows connection to each transducer in turn, and asimple, one-step connection for operation of pumps. When dedicated pumps are selected, it allowsindividual zones to be purged separately, or purging of many zones simultaneously to reduce fieldtirres.

Peimanent packers ensure long term integrity of seals in cored bedrock holes and cased wells. They usea water activated expansion sleeve fitted over the perforated packer body. A layer of porous plasticdistributes water evenly to the packer expansion material. A Rubber/Kevlar/Rubber sheath envelops theexpansion material. The Kevlar layer provides strength to bridge across large fissures. The pliant gumrutber forms an effective seal against the borehole wall. Water is added to the inside of the sealedcasing string after installation. The water passes through the packer body into the expansion sleeve,causing the material to expand. Thus an engineered seal is permanently formed against the boreholewall.

The Installer shall use Waterloo Systems Gas-Driven Double Valve Pumps supplied by Solist withsta nless steel and Teflon®D valves. The pumps are connected directly to the stem of each port and dualline polyethylene or Teflon(® tubing connects the pump to the wellhead manifold. The pumps will usemanual pump control units. They have quick-connect couplings with only a single connection to themanifold required. Samples from all levels are easily and rapidly obtained. Purging from some or alllevels simultaneously is accommodated by the multi-purge feature of the manifold.

ATTACHMENT 9.4 POST MODIFICATION TEST PLAN FORMSheet 3 of ';

2.0 Ro-k Face Logging

The Installer shall provide an expert geologist or geologic engineer to log the rock face exposed in theIP2-FSB. The bedrock face will be mapped and logged for lithology, bedding planes, fractures, jointsand faults. The three dimensional orientation of the surfaces will be recorded and evaluated. Theinformation will be used to understand the fracture orientations and their control on the hydrologicprocesses at the site.

3.0 Geophysical Well Logging

Prior to completing the wells as permanent monitoring wells, the ,Installer. shall conduct down-holegecphysical well-logging of the three completed borings adjacent to TP2-FSB. The well-logging willconsist of borehole temperature logging, fluid resistivity, 3-arn caliper logging, acoustical televiewerlogging (ATV) and heat pulse flow meter logging. The ATV log will provide data on fracture depth andorientation. The caliper log will provide information on depths of bedrock fractures. The fluid temperatureand fluid resistivity will provide information as to which fractures are productive.

4.0 Packer Testing

Baled upon review of the geophysical well logging results, the Installer shall select discreet intervals toconduct packer testing to assess hydraulic conductivity within the bedrock. Packer tests will be performedusing a double inflatable bladder and straddle packer assembly with a 10 FT long testing zone. Packertesting will begin at the highest testing zone and continue down the length of the uncased bedrock. Packertest intervals and test pressures will be determined in the field and recorded. The raw data will be reducedin the office and hydraulic conductivity values will be calculated using a computer program calledPermcalc, developed by GZA based on the methods presented in the US-DOI, "Groundwater Manual"..

5.0 Hydraulic Conductivity Tests

The Installer shall conduct hydraulic conductivity "pump/drawdown tests" at each of the existinggroundwater monitoring wells, as well as, the (6) new screened monitoring wells. The test generallyidentifies the rates of rising water through the surrounding soils for which the test is being conducted.Hydraulic conductivity and transmissivity are then calculated from those results. At each of the testedmonitoring wells, the resting (static) water level will be measured along with the depth and diameter ofthe well casing. An electrical submersible pump will be utilized to drawdown water in the well. Thepuraping rate will be adjusted until a steady state is achieved. Discharged water will be pumped to 275-galion plastic holding tanks. Approximately 350 gallons of water will be generated for each monitoringwell. Elapsed time and water levels will be manually recorded and recorded by a vibrating wiretransducer and data logger system at 10-second intervals. The test will be repeated at each testedmonitoring well. The resultant data will be evaluated to assess the hydraulic conductivity cf theformations.

6.0 Groundwater Santpling And Analysis

Following installation of the new monitoring wells, the Installer will collect groundwater samples fromeach of the previously installed wells and the newly installed wells. Groundwater samples will becollected using USEPA low flow procedures. Groundwater samples will be collected from five feetbelow the water table or adjacent to high permeability flow zones as documented by geophysicallogging. A decontaminated, stainless steel electrical submersible pump with controller and dedicatedtubing will used to perform the groundwater sampling activities. The wells will be pumped for purgingand sampling at a flow rate of between 250 to 500 mL per min (mlmin). Field parameters, includingp14, specific conductivity, turbidity, dissolved oxygen, temperature, and ORP, were measuredapproximately every five (5) -minutes-during the purge process at each well using a multi-parameterwaiter quality system. Purging will `eaisdwhen all or most field parameters have stabilized to within therange specified in the US-EPA "Groundwater Sampling Procedure For Low Stress Purging and Sampling".Gioundwater samples will be given to IPEC personnel who will be responsible for chemical analysis.

7.0 In tallation And Monitoring Of Pressure Transducers

In order to validate hydrogeology at the IPEC Site, the Installer will temporarily install In-situ Mini-Trollpressure transducers in existing on-site groundwater monitoring wells, as well as, the newly installed wells.In addition, the Installer will install (2) still wells which will house pressure transducers. One still well willbe installed on the west side of the Discharge Canal within the Hudson River. The second still well will beinstalled on the south end of the Drainage Canal within the Drainage Canal proper.

In order to install a transducer within well U3-T1, located on the bottom floor of the Unit 3 TurbineBuilding, the Installer will need to raise the existing stand pipe by 1.5 feet in order to minimize potentialseepage of groundwater, which is under pressure beneath the slab. The additional 1.5 feet of one-inchdiameter PVC riser pipe will be secured to the existing riser pipe using a PVC coupling and PVC glue.

The pressure transducers will be set one-foot off the bottoms of the wells with a maximum of 100 FT ofwater column above the transducer. The transducers will be set to record water levels in the wells on atspecific intervals. The information will aid in assessing tidal influences on groundwater at the Site, as wellas, assessing the flux of groundwater across the Site.

8.0 Elevation Survey

The Installer will locate and survey Monitoring Wells No. MW-3 I through No. MW-38. ThA longitude andlatitude of each well will be measured to the nearest second and the elevation of each well will be measuredto one-hundredth of a foot. The elevation of each well will be referenced to on-site datum. In addition,several catch basins and drainage points will be surveyed to determine their exact locations and elevations.

1.0 DESCRIPTION

1.1 Structures. Systems or Components Description

Monitoring Wells will be installed in the vicinity of the IP2-FSB, IP2 Transformer YardArea, Condenser Tube Withdrawal Pit, 1P2-TB Loading Bay and east side of theDischarge Canal, near the IP3 Security Command Post. The monitoring wells willprovide Entergy the ability to monitor groundwater and evaluate the following:

1.1.1 The source area concentrations of contaminants and the hydrogeology of thebedrock aquifer in the vicinity of the IP2-FSB.

1.1.2 The width of the potential plume, which may emanate from the IP2-FSB andwhich may be detected in existing Monitoring Well No. MW-I 11.

' " y;i 1.1.3 If contaminants may have entered the backfill around the DischargdCanal'.-

1.1.4 If contaminants may have migrated west of the Discharge Canal

1.1.5 If contaminants may have migrated along the backfill of the Discharge Canaltowards the Hudson River.

1.2 Reason For Chanee

As part of the IPEC Dry Cask Storage Project, a new single failure proof Gantry Cranewill be installed within the IP2 Fuel Storage Building (IP2-FSB) to transfer the HoltecInternational HI-TRAC to/from the IP2 Spent Fuel Pool (IP2-SFP). In order to facilitateinstallation of the North Pedestal Structure and the Steel Ballast Box Foundation, whichwill support the Gantry Crane, the existing IP2-FSB Truck Bay Floor, EL 80'-O" wasremoved from service. In addition, the sub-floor bedrock and soil, which is adjacent tothe south wall of the 1P2-SFP, was excavated to -EL 51 '-0". During recent excavationactivities, two hairline shrinkage cracks in the south wall of the IP2-SFP were exposed,which exhibited signs of moisture. One crack, which is located at -EL 61'-O" near thenorthwest corner of the excavated Truck Bay Area, was observed to be activelydischarging water at a rate of -1.5 Liters/Day. Radiochemistry testing indicatedconstituents found in the discharged water to be generally consistent with water typicallyassociated with the IP2-SFP. This adverse condition is documented in Condition ReportNo. CR-1P2-2005-03557. Currently, there are no available methods to monitorgroundwater in the vicinity of the IP2-FSB. As a result, IPEC cannot evaluate the sourceand extent of the potential leak from the IP2-SFP. In addition, IPEC cannot evaluate thehydrogeology in the vicinity of the IP2-FSB.

MONITORING WELL DEVELOPMENT PLAN

1.0 Multilevel Sampling Equipment

Tht Installer shall use a Waterloo Systems Multilevel Sampling System supplied by Solist. This systemuses modular components which form a sealed casing string of various casing lengths, packers, ports, abase plug and a surface manifold. This configuration allows accurate placement of ports at precisemonitoring zones. Monitoring tubes attached to the stem of each port individually connect that

-i monitoring zone to the surface. The standard system is built on 2"0 Schedule 80 PVC pipe to fit 3'- 4"7 diameter boreholes and uses 3 FT long packers. Stainless steel components, custom packer materials

and sizes, Teflon® tubing are available.

Monitoring ports are constructed from 316 Stainless Steel. Ports are isolated by packers at each desiredmonitoring zone and are individually connected to the surface manifold with narrow diameter tubing.Thus formation water enters the port, passes into the stem, up into the monitoring tube attached to thestem, to its static level. A sampling pump and pressure transducer will be dedicated to each monitoringzone by attachment to the port stem.

The manifold completes the system at surface. It organizes, identifies, and coordinates the tubes and/orcables from each monitoring zone. The manifold allows connection to each transducer in turn, and asimple, one-step connection for operation of pumps. When dedicated pumps are selected, it allowsindividual zones to be purged separately, or purging of many zones simultaneously to reduce fieldtirres.

Peimanent packers ensure long term integrity of seals in cored bedrock holes and cased wells. They usea vwater activated expansion sleeve fitted over the perforated packer body. A layer of porous plasticdis ributes water evenly to the packer expansion material. A Rubber/Kevlar/Rubber sheath envelops theexpansion material. The Kevlar layer provides strength to bridge across large fissures. The pliant gumrubber forms an effective seal against the borehole wall. Water is added to the inside of the sealedcasing string after installation. The water passes through the packer body into the expansion sleeve,causing the material to expand. Thus an engineered seal is permanently formed against the boreholewall.

The Installer shall use Waterloo Systems Gas-Driven Double Valve Pumps supplied by Solist withstainless steel and Teflon® valves. The pumps are connected directly to the stem of each port and dualline polyethylene or Teflon® tubing connects the pump to the wellhead manifold. The pumps will usemanual pump control units. They have quick-connect couplings with only a single connection t: themanifold required. Samples from all levels are easily and rapidly obtained. Purging from some or alllevels simultaneously is accommodated by the multi-purge feature of the manifold.

2.0 Rock Face Logging

The Installer shall provide an expert geologist or geologic engineer to log the rock face exposed in theIP2-FSB. The bedrock face will be mapped and logged for lithology, bedding planes, fractures, jointsand faults. The three dimensional orientation of the surfaces winl be recorded and evaluated. Theinformation will be used to understand the fracture orientations and their control on the hydrologicprocesses at the site.

3.0 Geophysical Well Logging

Prior to completing the wells.as nperpnanent monitoring wells, the Installer shall conduct down-holegeophysical well-logging of ite 6thre&1 completed borings adjacent to MP2-FSB. The well-logging willconsist of borehole temperature logging, fluid resistivity, 3-arm caliper logging, acoustical televiewerlogging (ATV) and heat pulse flow meter Jogging. The ATV log will provide data on fracture depth andori ntation. The caliper log will provide information on depths of bedrock fractures. The fluid temperatureand fluid resistivity will provide information as to which fractures are productive.

4.0 Parker Testing

Bas;ed upon review of the geophysical well logging results, the Installer shall select discreet intervals toconduct packer testing to assess hydraulic conductivity within the bedrock. Packer tests will be performedusing a double inflatable bladder and straddle packer assembly with a 10 FT long testing zone. Packertesting will begin at the highest testing zone and continue down the length of the uncased bedrock. Packertest intervals and test pressures will be determined in the field and recorded. The raw data will be reducedin the office and hydraulic conductivity values will be calculated using a computer program calledPermcalc, developed by GZA based on the methods presented in the US-DOI, "Groundwater Manual".

5.0 Hydraulic Conductivity Tests

The Installer shall conduct hydraulic conductivity "pump/drawdown tests" at each of the existinggroundwater monitoring wells, as well as, the (6) new screened monitoring wells. The test generallyidentifies the rates of rising water through the surrounding soils for which the test is being conducted.Hydraulic conductivity and transmissivity are then calculated from those results. At each of the testedmonitoring wells, the resting (static) water level will be measured along with the depth and diameter ofthe well casing. An electrical submersible pump will be utilized to drawdown water in the well. Thepumping rate will be adjusted until a steady state is achieved. Discharged water will be pumped to 275-gallon plastic holding tanks. Approximately 350 gallons of water will be generated for each monitoringwell. Elapsed time and water levels will be manually recorded and recorded by a vibrating wiretransducer and data logger system at 10-second intervals. The test will be repeated at each testedmonitoring well. The resultant data will be evaluated to assess the hydraulic conductivity of theforriations.

ATrACHM ENT 9.4 POST MODIFICATION TEST PLAN FORmSheet 4 of 5

6.0 Groundwater Sarupling And Analysis

Following installation of the new monitoring wells, the Installer will collect groundwater samples fromeach of the previously installed wells and the newly installed wells. Groundwater samples will becollected using USEPA low flow procedures. Groundwater samples will be collected from five feetbelow the water table or adjacent to high permeability flow zones as documented by geophysicallogging. A decontaminated, stainless steel electrical submersible pump with controller and dedicatedtubing will used to perform the groundwater sampling activities. The wells will be pumped for purgingand sampling at a flow rate of between 250 to 500 mL per min (mUmin). Field parameters, includingpE, specific conductivity, turbidity, dissolved oxygen, temperature, and ORP, were measured

%eaproximately every five (5) minutes during the purge process at each well using a multi.parameteri!;'wv.ter quality system. Purging will cease when all or most field parameters have stabilized touwithin the

range specified in the US-EPA "Groundwater Sampling Procedure For Low Stress Purging and Sampling".Groundwater samples will be given to IPEC personnel who will be responsible for chemical analysis.

7.0 Installation And Monitoring Of Pressure Transducers

In order to validate hydrogeology at the IPEC Site, the Installer will temporarily install In-situ Mini-Trollpressure transducers in existing on-site groundwater monitoring wells, as well as, the newly installed wells.In addition, the Installer will install (2) still wells which will house pressure transducers. One still well willbe installed on the west side of the Discharge Canal within the Hudson River. The second still well will beinstalled on the south end of the Drainage Canal within the Drainage Canal proper.

In order to install a transducer within well U3-TI, located on the bottom floor of the Unit 3 TurbineBuilding, the Installer will need to raise the existing stand pipe by 1.5 feet in order to minimize potentialseepage of groundwater, which is under pressure beneath the slab. The additional 1.5 feet of one-inchdiameterPVC riser pipe will be secured to the existing riser pipe using a PVC coupling and PVC glue.

The pressure transducers will be set one-foot off the bottoms of the wells with a maximum of 100 FT ofwater column above the transducer. The transducers will be set to record water levels in the wells on atspecific intervals. The information will aid in assessing tidal influences on groundwater at the Site, as wellas, assessing the flux of groundwater across the Site.

8.0 Elvation Survey

Th, Installer will locate and survey Monitoring Wells No. MW-3 I through No. MW-38. The longitude andlatitude of each well will be measured to the nearest second and the elevation of each well will be measuredto one-hundredth of a foot. The elevation of each well will be referenced to on-site datum. In addition,several catch basins and drainage points will be surveyed to determine their exact locations and elevations.
