RE: Annual groundwater monitoring report, Vermont Yankee Power Plant, SMS Site # 99-2617 Vernon, Vermont

Dear Ms. DeWald:

The SMS has reviewed the January 23, 2006 groundwater monitoring and product recovery report for samples collected on October 17, 2005 and product removal from December 2004 to December 2005. The report was prepared by Environmental Compliance Services. Drinking water samples are collected quarterly by Vermont Yankee with the most recent sample collected on December 12, 2005.

One or more of the following petroleum compounds: naphthalene, 1,2,4- and 1,3,5-trimethylbenzene were detected at levels above the Vermont Groundwater Enforcement Standards (VGES) in monitor wells MW-I and -8. MW-6 contained trace petroleum contaminants below the VGES. Monitor well MW-2 had tetrachloroethene (PCE) contamination above the VGES. MW-5 and -7 contained PCE below the VGES.

Monitor well MW-9 contained free product on the sample date and was not sampled. To date approximately 149 liters of free product have been recovered from MW-1, -6, -8, and -9..

Free product monitoring and recovery should continue to be performed on a quarterly, monthly, or weekly basis by Vermont Yankee personnel as needed. All monitor wells should be sampled via EPA Method 8260 for volatile organic compounds (VOCs) in Fall 2006. If any monitor wells contain measurable free product, they should not be sampled, and they should be reported as containing free product on the sample date.

The SMS looks forward to reviewing the next annual report by January 15, 2007. If I can be of assistance, please contact me at (802) 241-3877 or gerold.noves(state.vt.us.

1.0 INTRODUCTION

This report documents annual groundwater sampling results conducted at the No. 2 Fuel Oil release area located at Entergy Nuclear Vermont Yankee, LLC (Vermont Yankee) in Vernon, Vermont (the Site)(see Site Locus, Figure 1). It has been prepared by Environmental Compliance Services, Inc., (ECS) of Brattleboro, Vermont on behalf of Entergy Nuclear Northeast.

Vermont Yankee is a nuclear powered electrical generating station which has been in operation since 1972. In the spring of 1999 groundwater monitoring wells were installed in the vicinity of a former underground storage tank (UST) as part of an environmental assessment for the Site. Groundwater samples collected during the initial environmental assessment from the on-Site groundwater monitoring wells contained volatile organic compounds (VOCs) that exceeded Vermont Department of Environmental Conservation (VTDEC) Primary Groundwater Quality Standards (PGQS). An additional five (5) groundwater monitoring wells were installed at the Site during subsequent investigations. Light non-aqueous phase liquid (LNAPL) identified as #2 fuel oil was encountered in monitoring wells MW-1,

-8 and -9. The Site Investigation Report recommended free product recovery and natural attenuation with quarterly groundwater monitoring as a remedial alternative. Quarterly groundwater monitoring commenced in December 1999. The Sites Management Section (SMS) of the VTDEC issued Site #99-2617 in 1999. Beginning in 2002, monitoring was reduced to once annually.

Vermont Yankee began a free product collection program for monitoring wells MW-1 during July 1999, MW-6 during January 2004, MW-8 during December 1999, and MW-9 in November 2002. Due to heightened security, sampling in 2002 was performed by Vermont Yankee personnel.

This report summarizes the following:

" annual groundwater gauging and groundwater sample collection by ECS;

" fourth quarter drinking water sample data completed by Vermont Yankee personnel;

" LNAPL removal and recovery data compiled by Vermont Yankee personnel;

" annual report preparation by ECS, including conclusions and recommendations.

Annual Monitoring Report, Site #99-2617 Document: 04-201215.00\DecO5 report Vermont Yankee Nuclear Power Station January 23, 2006 Vernon, Vermont Page 2 2.0 GROUNDWATER AND DRINKING WATER MONITORING Annual groundwater gauging and sampling was performed by ECS personnel on October 17, 2005.

Depth to groundwater in each well was measured with a Solinst electronic oil and water interface probe (I-probe) level indicator from the top of the monitoring well PVC. The instrument is accurate to 0.01 foot.

Groundwater samples were collected from eight of the nine monitoring wells associated with the Site.

Well MW-9 was not sampled due to the presence of LNAPL on the sampling date. Groundwater samples were obtained using disposable plastic bailers following the purging of a minimum of three well volumes of groundwater (except for MW-3 which required a larger purge than could be accomplished in a reasonable amount of time by bailer sampling). Each collected sample was placed into two 40 milliliter (ml) glass VOA vials preserved with HCI. All samples including the trip blank were immediately stored on ice upon collection, and refrigerated until delivery was made to the Spectrum Analytical, Inc.

laboratory located in Agawam, Massachusetts. Samples were submitted for analysis of VOCs by EPA Method 8260. A copy of the groundwater gauging and sampling log is included in Appendix A.

All gauging data obtained to date from monitoring wells associated with the Site are presented in Table 1.

Depth to groundwater ranged from 17.63 feet to 18.27 feet. Groundwater elevations varied slightly since October 2004, with an average increase of 0.20 feet at the nine monitoring locations. The October 17, 2005 data was used to generate a groundwater potentiometric map presented as Figure 2.

Groundwater at the Site was determined to flow in a northerly direction during the October 2005 gauging event. This flow direction is consistent with past observations at the site. This flow direction may be influenced by building footprints, properties of geological features in the area, or other hydrological irregularities.

Contaminant concentrations at the site do not appear to be influenced by fluctuations in groundwater elevations observed at the site since 1999.

2.1 LABORATORY ANALYSIS OF DRINKING WATER SAMPLES Vermont Yankee personnel collected a drinking water sample from the COB potable water supply well (WSDT) # 20559) on February 9, May 10, July 28, and December 6, 2005. A summary table of the results of analyses on these samples is provided in Appendix B.

The December 6, 2005 drinking water sample collected from the COB system was analyzed for VOCs via EPA Method 524.2. The sample was collected at the first floor lunch room sink of the COB system. No parameters tested for in COB potable water supply well drinking water sample for the 12/6/05 were detected above Minimum Detection Limits (MIDLs). No contaminant concentrations detected in drinking water exceeded Vermont PGQS.

Annual Monitoring Report, Site #99-2617 Document: 04-201215.00\DecO5 report Vermont Yankee Nuclear Power Station January 23, 2006 Vernon, Vermont Page 3 2.2 LABORATORY ANALYSIS OF GROUNDWATER SAMPLES 2.2.1 VOC Analyses The groundwater samples obtained on October 17, 2005 were analyzed by EPA Method 8260.

Results are summarized in Table 2 and Table 3, which include VT PGQS and results of previous analyses for reference. The complete laboratory data sheets and chain of custody record are presented in Appendix C.

2.2.1.1 PetroleumHydrocarbons A summary of petroleum hydrocarbons detected in groundwater collected is presented as Table 2. A Naphthalene isoconcentration map constructed from the October 17, 2005 laboratory data is presented as Figure 3. Groundwater samples collected from monitoring wells MW-1, and MW-8 contained VOC concentrations that exceed VTDEC PGQS.

Although well MW-9 was not sampled due to the presence of LNAPL, it is assumed based upon historical data that PGQS were exceeded by VOC concentrations in groundwater at this monitoring point. The highest concentrations of dissolved petroleum VOCs were reported in the groundwater samples collected from monitoring well MW-8.

Concentrations of 1,2,4-Trimethylbenzene (124 micrograms per liter, lag/L), 1,3,5-Trimethylbenzene (53.6 pg/L) and Naphthalene (250 .igfL) were detected at MW-8.

Groundwater samples collected from MW-1 revealed concentrations of 1,2,4-Trimethylbenzene (69.2 jig/L), 1,3,5-Trimethylbenzene (46 jig/L), and Naphthalene (175

.tg/L) which exceed PGQS. Concentrations of petroleum hydrocarbons above PGQS were not reported in samples collected from monitoring wells MW-3, MW-4, MW-5 MW-6 or MW-7.

Contaminant concentrations in groundwater exhibited an increase in the sample from MW-1 compared to the data from October 2004, but data collected since 1999 suggest an overall decreasing trend at MW-i.

Contaminant concentrations in groundwater exhibited a decrease in the sample from MW-6 (to levels below PGQS) compared with the data from October 2004, and data collected since 1999 suggest an overall decreasing trend at MW-6.

Contaminant concentrations in groundwater exhibited a decrease in the sample from MW-8 compared to the last time the monitoring well was sampled in 2002, and there is insufficient historical data to suggest a trend. The presence of LNAPL in this monitoring well in 2003 and 2004; as well as its continued presence in MW-9 since 2003 suggests that contaminant levels will persist at these locations.

Graphs showing 1,2,4 & 1,3,5-Trimethylbenzenes and Napthalene concentrations, and groundwater elevations over time for monitoring wells MW-1, MW-6 and MW-8 are provided in Appendix D.

2.2.1.2 ChlorinatedVOCs and Ketones Historical laboratory data relating to chlorinated VOCs and Ketones is included as Table

3. Groundwater samples collected from monitoring wells MW-2, MW-5, and MW-7

Annual Monitoring Report, Site #99-2617 Document: 04-201215.00\DecO5 report Vermont Yankee Nuclear Power Station' January 23, 2006 Vernon, Vermont Page 4 contained concentrations of Tetrachloroethene (PCE), with the reported concentration of 13.7 jig/L at MW-2 exceeding VTDEC PGQS.

PCE concentration in groundwater exhibited an increase in the sample from MW-2 compared to the data from October 2004, but data collected since 1999 suggest an overall decreasing trend in PCE concentration at MW-2. A graph of PCE concentration and groundwater elevation over time at monitoring well MW-2 is included in Appendix D.

The only other chlorinated VOC reported in samples above MDLs was 1 jig/L of TCE reported in the MW-2 sample, which is below the VTDEC PGQS.

Annual Monitoring Report, Site #99-2617 Document: 04-201215.00\DecO5 report Vermont Yankee Nuclear Power Station January 23, 2006 Vernon, Vermont Page 5 3.0 RESULTS OF LNAPL REMOVAL ACTIVITIES Vermont Yankee personnel completed LNAPL gauging and removal activities throughout the monitoring period by gauging monitoring wells MW-1, -6, -8, and -9 with a GeoTech I-probe and removing any detected LNAPL with a disposable bailer. All product and groundwater collected is placed into a 55 gallon drum for disposal.

Vermont Yankee initiated weekly LNAPL recovery efforts in November 2002 due to the discovery of 3 feet of LNAPL in MW-9. During the October 2005 sampling event, 0.01 foot of product was noted in MW-9 and sheen of product was noted in MW-1, MW-6 and MW-8.

From December 2004 to December 2005, 0.1 milliliters (ml) of fuel oil was recovered from MW-1, a total of approximately 2.6 ml from MW-6, 0.8 ml from MW-8, and 15.2 ml from MW-9. To date, total recovery amounts of fuel oil are 2.23 liters from MW-1, 17.9 ml from MW-6, 26.08 liters from MW-8, and 120.68 liters from MW-9. A free product recovery table for December 2004 through December 2005 is included as Table 4.

4.0 CONCLUSION

S Based on the information provided by Vermont Yankee and review of the laboratory reports of analyses completed on sampled collected by ECS on October 19, 2004, the following conclusions are made:

Depth to groundwater ranged from 17.63 feet to 18.27 feet. Groundwater elevations increased an average of 0.20 feet since 2004 based on the data collected from nine monitoring wells.

Groundwater flow is interpreted to flow in an easterly direction towards the Connecticut River, which is consistent with past observations at the site.

" LNAPL was present on the water table at monitoring well MW-9 in a measurable quantity during the sampling event, and during LNAPL recovery events at monitoring wells MW-I, MW-6, MW-8 and MW-9.

Groundwater samples collected from monitoring wells MW-i and MW-8 contained Petroleum Hydrocarbon concentrations that exceed VTDEC PGQS.

" The concentrations of PCE detected at MW-2 exceeded PGQS.

Dissolved concentrations of petroleum hydrocarbons exhibited an increase at MW-i; and a decrease at MW-6 from October 2004 to October 2005, and a decrease at MW-8 from October 2002 to October 2005.

From December 2004 to December 2005, 0.1 milliliters (ml) of fuel oil was recovered from MW-1, a total of approximately 2.6 ml from MW-6, 0.8 ml from MW-8, and 15.2 ml from MW-9. To date, total recovery amounts of fuel oil are 2.23 liters from MW-1, 17.9 nil from MW-6, 26.08 liters from MW-8, and 120.68 liters from MW-9.

Annual Monitoring Report, Site #99-2617 Document: 04-201215.00\DecO5 report Vermont Yankee Nuclear Power Station January 23, 2006 Vernon, Vermont Page 7 5.0 RECOMMENDATIONS

" ECS recommends continuing the annual groundwater sampling program for selected wells, with the analysis of VOCs via EPA Method 8260. The next annual sampling event is scheduled for October 2006. Results shall be presented in an annual report including field data, laboratory data sheets, groundwater and isoconcentration maps, conclusions and recommendations.

ECS recommends the continuation of LNAPL removal on a bi-weekly schedule at monitoring wells MW-1, -8, and -9.

Notes and Definitions QC-1 Analyte out of acceptance range.

QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery.

QR-02 The RPD result exceeded the QC control limits; however, both percent recoveries were acceptable. Sample results for the QC batch were accepted based on percent recoveries and completeness of QC data.

VOCI I Analyte presence was confirmed by duplicate analysis.

BRL Below Reporting Limit - Analyte NOT DETECTED at or above the reporting limit dry Sample results reported on a dry weight basis NR Not Reported RPD Relative Percent Difference A plus sign (+) in the Method Reference column indicates the method is not accredited by NELAC.

Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to document laboratory performance.

Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.

Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.

Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank is used to document contamination resulting from the analytical process.

Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99%

confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the analyte.

Reportable Detection Limit (RDU: The lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest non-zero standard in the calibration curve. While the RDL is approximately S to 10 times the MDL, the RDL for each sample takes into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.

Sample RDLs are highly matrix-dependent.

Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and Validated by:
