{{#Wiki_filter:11.0   RECOMMENDATIONS Based upon the comprehensive groundwater investigation and other work performed by Entergy, GZA recommends the following:
: 1. Repair the identified Unit 2 Transfer Canal liner weld imperfection (completed mid December 2007);2. Continue source term reduction in the Unit I pool via the installed demnineralization system;3. Remove the remaining Unit 1 fuel and drain the pools; and 4. Implement long term monitoring consistent with monitored natural attenuation, property boundary monitoring, future potential leak identification, and support of ongoing dose assessment.

It is GZA's opinion that our investigations have characterized the hydrogeology and radiochemistry of the groundwater regime at the Site. Therefore, we are not recommending further subsurface investigations (see Section 10.0). Based upon the findings and conclusions from these investigations, as well as other salient Site operational information, we recommend the completion of source interdiction measures with Monitored Natural Attenuation (MNA) as the remediation technology at the Site. In no small part, this recommendation is made because of the low potential for risk associated with groundwater plume discharge to the Hudson River.Monitored Natural Attenuation is defined by the United States Environmental Protection Agency as the reliance on natural attenuation processes (within the context of a carefully controlled and monitored clean up approach) to. achieve Site-specific remedial objectives within a time frame that is reasonable compared to other methods. The "natural attenuation processes" that are at work in the remediation approach at this Site include a variety of physical, chemical and radiological processes that act without human intervention to reduce the activity, toxicity, mobility, volume, or concentration of contaminants in soil and groundwater.

Monitored Natural Attenuation is defined by the United States Environmental Protection Agency as the reliance on natural attenuation processes (within the context of a carefully controlled and monitored clean up approach) to. achieve Site-specific remedial objectives within a time frame that is reasonable compared to other methods. The "natural attenuation processes" that are at work in the remediation approach at this Site include a variety of physical, chemical and radiological processes that act without human intervention to reduce the activity, toxicity, mobility, volume, or concentration of contaminants in soil and groundwater. These primarily include radiological decay, dispersion,.and sorption.

MNA is typically used in conjunction with active remediation measures (e.g., source control), or as a follow-up to active remediation measures that have already been implemented. At: IPEC, active remedial measures already implemented include elimination (e.g., repair of the Unit 2 1990 liner leak and repair of Transfer Canal weld imperfection in mid-December 2007) and/or control (e.g., installation of a collection box to capture moisture from the IP2 shrinkage cracks) of active leaks, and reduction of the source term in the Unit I fuel storage pool through demineralization, with subsequent planned removal of the source term (fuel rods) followed by complete draining of the IP1-SFPs.

These decreases are consistent with a reduction in the concentrations in the Unit I West Fuel Pool via pool water recirculation through demineralization beds. While the physical leak(s) in this fuel pool still exist, the source term to the groundwater has been reduced due to treatment of the source water. Further planned interdictions include removal of the fuel rods and draining of the pool water, which will permanently eliminate the West Fuel Pool as a source of contamination to the groundwater.

: c. The Unit I plume in the Unit 3 area has been attributed to a historic legacy discharge from the Sphere Foundation Drain Sump (SFDS) through the storm drain system which traverses along the southeastern portion of the Site. Leaks from this storm drain system have, in turn, resulted in past contamination of the groundwater along the storm drains, with subsequent groundwater migration westward, through Unit 3 toward the river..The SFDS no longer discharges to the storm drain and the Strontium concentrations in the Unit 3 groundwater -have decreased to low levels, consistent with natural attenuation processes.

With the implemented physical containment of the associated 2005 "concrete wall crack leaks" and the repair of the Transfer Canal liner, the source of contamination to the groundwater has been reduced and controlled.
: 2. GZA selected Monitored Natural Attenuation as the remediation strategy because: a. Interdiction measures undertaken and planned to date have, or are expected to, eliminate/control active sources of groundwater contamination.

off-Site migration of contaminated groundwater to the North, South or East.c. Consistent with the Conceptual Site Model, no contaminants have been detected above regional background in any of the off-Site monitoring locations or drinking water supply systems in the region.d. The only on-Site exposure route for the documented contamination is through direct exposure.
The SFDS no longer discharges to the storm drain and the Strontium concentrations in the Unit 3 groundwater -have decreased to low levels, consistent with natural attenuation processes.
Because: the majority of the Site is capped by 135 impermeable surfaces, there is no uncontrolled direct contact with contaminants.

: e. Our studies indicate that under existing conditions, the spatial extent of the groundwater plume will decrease with time.f. Groundwater is not used as a source of drinking water on the Site or in the immediate vicinity of the Site, and there is no reason to believe that this practice will change: in the foreseeable future.g. Groundwater associated with the Unit I foundation drainage systems is captured and treated to reduce contaminants prior to discharge to the Discharge Canal, consistent with ALARA principles.
: a. Interdiction measures undertaken and planned to date have, or are expected to, eliminate/control active sources of groundwater contamination.
: h. At the locations where contaminated groundwater discharges to the Hudson River, the concentrations have been, and will continue to be, reduced by sorption, hydrodynamic dispersion and radiological decay. No detections of contaminants associated with plant operations have been found in the Hudson River or biota sampled as part of the required routine environmental sampling..1.. More aggressive technologies would alter groundwater flow patterns and, therefore, in our opinion, offer no clear advantages.

.The second primary requirement for implementation of MNA is a demonstration that contaminant migration is consistent with the Conceptual Site Model. In particular, rigorous monitoring is required to demonstrate reductions-in source area contamination, reductions in plume contaminant concentrations, and reduction in contaminant discharge to the river over time. The initial implementation stages of this monitoring process were begun nearly two years ago as part of the investigations summarized herein. As outlined above, reductions in maximum groundwater plume contaminant concentrations have already been documented.

The elements for long term monitoring, consistent with the objectives of the NEI Groundwater Protection Initiative, arein place. We further note: a. Groundwater wells have specifically been installed, and are currently being monitored, to both detect and characterize current and potential future off-Site groundwater contaminant migration to the river.

The long term monitoring plan should include action levels, which if exceeded, trigger further analysis and/or investigations, potentially leading to implementation of an interdiction plan, if required.f. A number of individual vertical sampling zones were included in nearly all the monitoring well installations, particularly within the contaminant plumes and at the location of plume discharge to the river.

11.0 RECOMMENDATIONS Based upon the comprehensive groundwater investigation and other work performed by Entergy, GZA recommends the following:

1. Repair the identified Unit 2 Transfer Canal liner weld imperfection (completed mid December 2007);
2. Continue source term reduction in the Unit I pool via the installed demnineralization system;
3. Remove the remaining Unit 1 fuel and drain the pools; and
4. Implement long term monitoring consistent with monitored natural attenuation, property boundary monitoring, future potential leak identification, and support of ongoing dose assessment.

It is GZA's opinion that our investigations have characterized the hydrogeology and radiochemistry of the groundwater regime at the Site. Therefore, we are not recommending further subsurface investigations (see Section 10.0). Based upon the findings and conclusions from these investigations, as well as other salient Site operational information, we recommend the completion of source interdiction measures with Monitored Natural Attenuation (MNA) as the remediation technology at the Site. In no small part, this recommendation is made because of the low potential for risk associated with groundwater plume discharge to the Hudson River.

Monitored Natural Attenuation is defined by the United States Environmental Protection Agency as the reliance on natural attenuation processes (within the context of a carefully controlled and monitored clean up approach) to. achieve Site-specific remedial objectives within a time frame that is reasonable compared to other methods. The "natural attenuation processes" that are at work in the remediation approach at this Site include a variety of physical, chemical and radiological processes that act without human intervention to reduce the activity, toxicity, mobility, volume, or concentration of contaminants in soil and groundwater. These primarily include radiological decay, dispersion,.and sorption.

MNA is typically used in conjunction with active remediation measures (e.g., source control), or as a follow-up to active remediation measures that have already been implemented. At: IPEC, active remedial measures already implemented include elimination (e.g., repair of the Unit 2 1990 liner leak and repair of Transfer Canal weld imperfection in mid-December 2007) and/or control (e.g., installation of a collection box to capture moisture from the IP2 shrinkage cracks) of active leaks, and reduction of the source term in the Unit I fuel storage pool through demineralization, with subsequent planned removal of the source term (fuel rods) followed by complete draining of the IP1-SFPs.

Remediation

1. Our recommendation of MNA principles includes source term contaminant reduction as an integral part of this remediation strategy. Data demonstrating plume concentration reductions over time, as considered along with other salient 134

Site information, are consistent with a conclusion that the interdiction efforts to date (both current and in the past) have resulted in: 1) termination of the identified Tritium leaks in the IP2-SFP; 2) identification of an imperfection in a Unit 2 Transfer Canal weld which has been repaired; 3) reduction in IP1-SFP contaminant concentrations; and 4) elimination of Sphere Foundation Drain Sump discharges to,

.the storm drain piping East of Unit 3. As such, these interdictions have resulted in the elimination and/or control of identified sources of contamination to the groundwater, as required:

zv a. Over the last two years, the highest Tritium concentrations in the Unit 2 plume have decreased. These data are consistent with a conclusion that the leaks :responsible for the currently monitored Tritium plume are related primarily to the previously repaired. 1992 legacy liner leak and the imperfection in the Transfer Canal weld. With the implemented physical containment of the associated 2005 "concrete wall crack leaks" and the repair of the Transfer Canal liner, the source of contamination to the groundwater has been reduced and controlled.

b. Over the last two years, the highest radionuclide concentrations in the Unit I plume have decreased. These decreases are consistent with a reduction in the concentrations in the Unit I West Fuel Pool via pool water recirculation through demineralization beds. While the physical leak(s) in this fuel pool still exist, the source term to the groundwater has been reduced due to treatment of the source water. Further planned interdictions include removal of the fuel rods and draining of the pool water, which will permanently eliminate the West Fuel Pool as a source of contamination to the groundwater.
c. The Unit I plume in the Unit 3 area has been attributed to a historic legacy discharge from the Sphere Foundation Drain Sump (SFDS) through the storm drain system which traverses along the southeastern portion of the Site. Leaks from this storm drain system have, in turn, resulted in past contamination of the groundwater along the storm drains, with subsequent groundwater migration westward, through Unit 3 toward the river..

The SFDS no longer discharges to the storm drain and the Strontium concentrations in the Unit 3 groundwater -have decreased to low levels, consistent with natural attenuation processes.

2. GZA selected Monitored Natural Attenuation as the remediation strategy because:
a. Interdiction measures undertaken and planned to date have, or are expected to, eliminate/control active sources of groundwater contamination.
b. Groundwater flow at the Site precludes. off-Site migration of contaminated groundwater to the North, South or East.
c. Consistent with the Conceptual Site Model, no contaminants have been detected above regional background in any of the off-Site monitoring locations or drinking water supply systems in the region.
d. The only on-Site exposure route for the documented contamination is through direct exposure. Because: the majority of the Site is capped by 135

impermeable surfaces, there is no uncontrolled direct contact with contaminants.

e. Our studies indicate that under existing conditions, the spatial extent of the groundwater plume will decrease with time.
f. Groundwater is not used as a source of drinking water on the Site or in the immediate vicinity of the Site, and there is no reason to believe that this practice will change: in the foreseeable future.
g. Groundwater associated with the Unit I foundation drainage systems is captured and treated to reduce contaminants prior to discharge to the Discharge Canal, consistent with ALARA principles.
h. At the locations where contaminated groundwater discharges to the Hudson River, the concentrations have been, and will continue to be, reduced by sorption, hydrodynamic dispersion and radiological decay. No detections of contaminants associated with plant operations have been found in the Hudson River or biota sampled as part of the required routine environmental sampling.

.1.. More aggressive technologies would alter groundwater flow patterns and, therefore, in our opinion, offer no clear advantages.

Lone~ Term Monitorino

. The second primary requirement for implementation of MNA is a demonstration that contaminant migration is consistent with the Conceptual Site Model. In particular, rigorous monitoring is required to demonstrate reductions-in source area contamination, reductions in plume contaminant concentrations, and reduction in contaminant discharge to the river over time. The initial implementation stages of this monitoring process were begun nearly two years ago as part of the investigations summarized herein. As outlined above, reductions in maximum groundwater plume contaminant concentrations have already been documented.

The elements for long term monitoring, consistent with the objectives of the NEI Groundwater Protection Initiative, arein place. We further note:

a. Groundwater wells have specifically been installed, and are currently being monitored, to both detect and characterize current and potential future off-Site groundwater contaminant migration to the river. Additional wells have also been installed for monitoring of other Site property boundaries.
b. Monitoring wells have also been installed just. downgradient of identified critical Structures, Systems and Components (SSCs). These wells, in concert with specific footing drain monitoring, provide earlier detection of potential future leaks associated with the power generating units than would be possible with boundary wells alone.

c.' Monitoring wells have been strategically placed to monitor the behavior of the plumes identified on the Site.

d. MW-38 and MW-48 should be excluded from the monitoring plan as samples from these wells are generally indicative of a mixed groundwater 136

and Discharge Canal/river water condition and, therefore, are not completely groundwater specific133 .

e. The long term monitoring plan should include action levels, which if exceeded, trigger further analysis and/or investigations, potentially leading to implementation of an interdiction plan, if required.
f. A number of individual vertical sampling zones were included in nearly all the monitoring well installations, particularly within the contaminant plumes and at the location of plume discharge to the river. These individual vertical monitoring zones provide a significant level of vertical resolution rAMV and also provide a substantial degree of redundancy relative to the longevity and efficacy of the monitoring network over time' 34
g. While previous and current dose calculations are both reasonable and conservative, we recommend that, with the accumulation of additional Site-specific hydrogeologic information, the calculations be modified to incorporate Site-specific transmissivities and groundwater gradients.

Entergy has agreed that Site-specific model information will be utilized in the next NRC required annual assessment of dose from this pathway. Our specific recommendations (which will include additional trend information in early 2008) will be provided under separate cover for Entergy's incorporation to support the annual report.

133 See Section 6.6.3 for further discussion pursuant to this conclusion.

1T1he level of redundancy designed into the long term monitoring network anticipates and allows for the loss of a number of monitoring zones without significant impact to the adequacy of the monitoring system.
