Mr. Harold C. Gillespie Unit Coordinator - Industrial Solid Waste Unit Georgia Environmental Protection Division 4244 International Parkway, Suite 104 Atlanta, GA 30354

Dear Mr. Gillespie:

Pursuant to EPD Solid Waste Rule 391-3-4-.14 and in accordance with the approved Plant Vogtle Landfill #2 and #3 Groundwater Monitoring Plans, Southern Nuclear is submitting the attached semi-annual groundwater monitoring report which was prepared for Southern Nuclear by the Dextra Group. This report presents the results for analysis of groundwater samples taken in December 2004. Samples from all monitoring wells at Landfill #2 and Landfill #3 were analyzed for Chapter 391-3-4 Appendix I parameters. In addition, due to a statistically significant increase over background detected during the June 2004 monitoring event, samples from Landfill #3 well GWA-7 were analyzed for Chapter 391-3-4 Appendix II parameters and due to the detection of the Appendix II parameter mercury in previous sampling events, all monitoring wells at Landfill #3 were analyzed for mercury.

As discussed in Sections 5 and 6 of the attached report, there was no statistically significant increase over background for any parameter detected in the compliance wells at Landfill #2. At Landfill #3 there was a statistically significant increase over background for barium and 1, 1-dichloroethane in wells GWC-13 and GWC-14; trichlorofluoromethane in wells GWC-13 and GWA-7; and cis-1 ,2-dichloroethane in well GWC-14. There was also a detection of mercury in Landfill #3 wells GWA-7 and GWA-

15. Statistical analysis for mercury was not performed because there are fewer than four complete data sets for mercury analysis.

1- Introduction This report presents the results of groundwater sampling conducted in December 2004 at two private solid waste landfills (Landfill #2 and Landfill #3) operated by Southern Nuclear Operating Company, Inc. (SNC) at Plant Vogde in Waynesboro, Georgia. Groundwater monitoring was initiated in 2002 in accordance with the approved Groundwater Monitoring Plan for the landfills.

The landfills are operated under Solid Waste Permit #s 017-006D(L)(I) and 017-007D(L)(I) and are used for disposal of non-putrescible, non-liquid office and solid waste as well as construction/demolition debris such as asbestos insulation, wooden pallets and concrete. The active trench at Landfill #2 is used only for asbestos disposal. Landfill #3, permitted in 1987, has been utilized solely for construction and demolition debris disposal since 1992.

Sampling, analyses and data evaluation were conducted in accordance with the rules of the Georgia Department of Natural Resources Environmental Protection Division (EPD), Chapter 391-3-4, the September 1991 "Manual for Groundwater Monitoring" and the approved Groundwater Monitoring Plan for the landfills.

The Endings of the initial four sampling events, conducted from August 2002 through December 2002, and subsequent semi-annual sampling events are presented in reports previously submitted to the EPD. This report presents the results of the December 2004 semi-annual monitoring event.

Subsequent reports will be prepared upon completion of semi-annual monitoring events as scheduled in the Groundwater Monitoring Plan.

2 - Monitoring Well Network The groundwater monitoring well network consists of four permanent monitoring wells located along the north, east and south waste unit management boundaries of Landfill #2 (Figure 1), and seven permanent monitoring wells located along the perimeter of the waste management unit boundary of Landfill #3 (Figure 2). As shown in the Egures, the wells are located outside of, but as close as practical to, the waste disposal areas. The wells are screened within the uppermost water-producing zones underlying the landfills, which occur from approximately 35 to 60 feet below land surface at Landfill #2 and from approximately 30 to 50 feet below land surface at Landfill #3.

The four permanent groundwater monitoring wells at Landfill #2 were installed in September 2001 after advancing a total of eight deep soil borings around the landfill boundary. The upgradient well is GWA-2/MW-2 and the downgradient, or compliance, wells are GWC-3/MW-3, GWB-4/MW-4 and GWC-11/MW-11. The well construction details are presented in Table 1. The wells will be referred to as GWA-2, GWC-3, GWB-4 and GWC-11 in this report consistent with the EPD's well identification guidelines.

The seven permanent groundwater monitoring wells at Landfill #3 were installed in September 2001 and in July 2002. The well construction details are presented in Table 2. Wells GWA-7/MW-7 and GWA-15/MW-15 are located at the south and southwest portions of the landfill boundary. Wells GWC-5/MW-5, GWC-13/MW-13 and GWC-14/MW-14 are located along the eastern portion of the landfill boundary, and wells GWB-6/MW-6 and GWB-16/MW-16 are located along the northern landfill boundary. Well GWA-7/MW-7 was initially treated as a compliance (downgradient) well for Landfill #3. However, due to review of water level measurements showing this well to be side gradient from the active fill area of the landfill, well GWA-7/MW-7 was evaluated as a background well in the monitoring reports from the June 2003 and December 2003 sampling events. Based on the consistent detection of trichlorofluoromethane and the June 2004 detection of trichloroethene in Well GWA-7/MW-7, it was decided to return to evaluating this well as a compliance well. This

-, approach was used in the June 2004 monitoring report and was continued in this monitoring report.

The most appropriate designation for this well will continue to be evaluated in light of future monitoring results. For this report, well GWA-15/MW-15 is the designated background well, and the remaining wells are designated compliance wells. The wells will be referred to as GWC-5, GWB-6, GWA-7, GWC-13, GWC-14, GWA-15 and GWB-16 in this report in accordance with the EPD's well identification guidelines.

Two stormwater sediment ponds were completed in 2004 in accordance with the approved Design and Operational Plan for the Vogtle Landfill #3. As there was no discharge from either pond at the time of the December 2004 groundwater monitoring event, no surface water samples were collected from the surface water monitoring stations located at the pond outfalls.

3 - Groundwater Flow Rate and Directional Data 3.1 Geology/Hydrogeology The geology of the Plant Vogtle site consists of sedimentary deposits within the Coastal Plain physiographic province of Georgia. These sediments consist of unconsolidated sands, silts and clays comprised of marine and non-marine fluvial deposits. Marls and limestone were also encountered at depth in deep borings completed at the landfills. A boring completed to approximately 126 feet below land surface at the northwest boundary of Landfill #2 appears to have been completed just into or immediately on top of the Utley Limestone member. The marls encountered during drilling were components of the Irwinton Sand member. Either all or parts of the Barnwell Group members (except the Utley Limestone member) were also encountered in the other borings conducted at the landfills. Underlying the Barnwell Group is the Lisbon Formation with its uppermost unit, the Blue Bluff Marl, located immediately under the Utley Limestone. This marl layer, approximately 70 feet thick, is a near-impermeable layer that effectively confines the Tertiary and Cretaceous aquifers, the two confined aquifers beneath the Plant site.

The occurrence of groundwater underlying the landfills appears in confined, semi-confined, unconfined, and perched hydrogeologic units. Groundwater is found primarily in sands, silty sands, clayey sands and marl limestone interfaces. The main difference between boring/well water production characteristics and aquifer confining characteristics appears to be the thickness of the water-producing zone, the grain size of the sand component, the sand/clay ratio and the characteristics of the marl/limestone interface.

Groundwater may also exist in an unconfmed water table aquifer in the Barnwell sands and limestone that overlie the marl. The water table aquifer at the site is on an interfluvial ridge, or a topographically high area in which the groundwater in the water table discharges along streams that surround the topographic high. The streams eventually discharge to the Savannah River.

3.2 Groundwater Elevations and Gradients During well installation, the occurrence of groundwater was determined by collecting continuous split spoon samples beginning approximately five feet above the location of expected groundwater-producing zones. At both landfills, groundwater was generally found in water producing zones less than one foot thick and was observed to be under semi-confined or confined conditions.

- Upon completion of all drilling activities, measuring points were located on the tops of the well casings and surveyed relative to mean sea level (msl). During each sampling event, depth to water measurements were recorded in the wells from the surveyed elevations using an electronic water-level 2

indicator. The water level measurements were then subtracted from the appropriate measuring point elevations to determine groundwater elevations in the wells.

Hydraulic conductivity (K) in the wells was measured on September 26, 2001. The values ranged from 5.634 x 10-4 cm/sec in GWB-6 to 3.064 x 10-2 cm/sec in GWA-2.

Landfill #2 Depth to water measurements and groundwater elevations for the wells at Landfill 2 are presented in Table 1. Groundwater elevations measured during the sampling events to date indicate groundwater underneath Landfill 2 trends from a relatively higher elevation at the eastern/northeastern portion of the landfill (GWA-2) to relatively lower elevations to the west/southwest beneath the landfill (Figure 1). Well GWC-11 is not used to construct the potentiometric surface map because the uppermost water-bearing unit at this location appears to be within a different hydrologic zone based on the significantly lower groundwater elevation measured in well GWC-11 compared to wells GWA-2, GWC-3 and GWB-4.

The hydraulic gradient of 0.01 (shown on Figure 1 for December 2004) was calculated using a three-point problem from potentiometric surface elevations in monitoring wells GWA-2, GWC-3 and GWB-4. The calculations used in determining the gradient are provided in Appendix A. The hydraulic gradient has ranged from a minimum of 0.01 (October 2002 and December 2004) to a maximum of 0.08 aune 2003).

Landfill #3 Depth to water measurements and groundwater elevations for the wells at Landfill #3 are presented in Table 2. Groundwater elevations measured to date indicate that the groundwater elevation, or

,,-.-, hydraulic 'head,' is greatest beneath the center area of the landfill, and decreases to the southeast, to the northeast and to the west-southwest beneath the landfill. This mounding effect is believed to be the result of natural inftltration in the sandy soils within the historic topographically high area in the center of the landfill. This topographically high area, which encompasses a broad area within the landfill, is a natural site feature that was present prior to any landfilling operations. Figure 2 shows the topography of the landfill. The topographically high area is now centered in the north middle portion of the landfill near well GWB-6.

As discussed previously, the water-bearing stratigraphy beneath Landfill #3 is composed of individual saturated sand units within a clayey/marl matrix. These units mayor may not be interconnected. As such, groundwater elevations in the monitoring wells may reflect head in multiple perched layers and may not represent groundwater 'flow' direction beneath the landfill. Figure 2 presents a map depicting the saturated head contours measured on December 28, 2004.

Monitoring well GWA-15 is the well most representative of background water quality at the site because of the distance between the well and the current landfilled area, and the location of the area of relatively higher head located between the well and the current landfilled area on the eastern portion of the site. This well is therefore used as a background well to evaluate groundwater quality at the landfill. Well GWA-7 is now evaluated as a downgradient well based on review of the groundwater elevation and chemical analysis data collected since 2002.

The hydraulic gradient was calculated using a three-point problem from groundwater elevations in the monitoring wells as follows for each main direction of head difference:

Southwest: GWB-6, GWA-7 and GWA-15; 3

Northeast: GWC-13, GWB-6 and GWC-5; and Southeast: GWC-13, GWA-7 and GWC-14.

The calculated hydraulic gradients are presented on the contour map (Figure 2). The calculations used in determining the gradients are provided in Appendix A. For the December 2004 event, the southwest gradient was 0.01, the northeast gradient was 0.09, and the southeast gradient was 0.12.

The southwest gradient has typically been 0.01, with a maximum of 0.02 Oune 2003), reflecting the consistently flattest gradient across the landfill. The northeast trending gradient has ranged from a minimum of 0.08 (October and December 2002, June 2004) to a maximum of 0.17 Oune 2003). The southeast gradient has ranged from a low of 0.06 (December 2002) to a maximum of 0.16 Oune 2003). For this monitoring event, the steepest gradient was observed in the southeast flow component.

4 - Sampling Procedures and Parameter Analyses 4.1 Procedures and Field Measurements Prior to sample collection during each sampling event, depth to water measurements are recorded in each well from the surveyed elevations using an electronic water level indicator. The water level indicator is decontaminated using a potable water and Alconox wash and a distilled water rinse between use at each well. The water level measurements are then subtracted from the appropriate measuring point elevations to determine the groundwater elevations in the wells.

Groundwater samples were collected from all monitoring wells after the wells were properly purged according to the EPA document entitled Low-Flow Purging & Sampling of Groundwater Monitoring Wells (Bulletin QAD023)". The wells were purged and sampled using QED SamplePro pumps equipped with Teflon bladders. Purge rates were matched to the recovery rates of the wells, verified by periodic depth to water measurements to determine draw-down during purging. Purging was conducted until at least three consecutive stable readings of pH, conductivity, and turbidity were recorded. Groundwater samples were then collected directly into pre-preserved sample containers supplied by the laboratory. Final measurements of pH, conductivity, and turbidity were performed to verify that these parameters remained stable during sampling. All field instruments were calibrated in the field daily prior to use and at the conclusion of each sampling event. The field measurements are provided in Tables 3and 4.

After each sample was collected, the SamplePro pumps and airlines were decontaminated according to the following protocol:

• The pump and air line were placed on clean plastic;

• The pump was disassembled and the bladder was removed;

• The pump was sprayed with a potable water and Alconox solution, followed with a distilled water rinse until all soap residue was removed;

• A new pump bladder was then installed in the pump prior to reassembly; and

• The pump airline was placed in a clean plastic bag between use at each well.

4.2 Parameter AnalYses In accordance with the approved Groundwater Monitoring Plan, the groundwater samples and field and laboratory quality assurance/quality control (QA/Qc) samples were analyzed for the Chapter 391-3-4 Appendix I list of parameters, which consists of total metals and volatile organic compounds (Table 5). The field QA/QC samples consisted of duplicate samples, trip blanks and equipment 4

blanks. Metals analyses were conducted using EPA Methods 6010B/7841, and VOCs analyses were conducted using EPA Methods 6010B/8260B and 504.1 to provide sufficiently sensitive quantitation limits for comparison with maximum contaminant limits. Advanced Chemistry Labs, Inc., Atlanta, Georgia performed the laboratory analyses. The complete laboratory analytical reports, which include field and laboratory QA/QC results and chain-of-custody forms, are provided in Appendix B.

In addition, samples were collected for the Chapter 391-3-4 Appendix II parameter mercury in all wells due to this parameter's detection in previous assessment monitoring conducted at the landfill.

The well GWA-7 was also scheduled for full Appendix II analysis during the December 2004 sampling event as this well indicated a statistically significant increase above background for the Appendix I parameter trichlorofluoromethane during the previous June 2004 sampling. The Appendix II parameter groups base neutral/acid extractables, cyanide and sulfide were inadvertently omitted from the GWA-7 sample analysis in December 2004. This was communicated to Mr. Earl Hinkle of EPD in February 2005 and it was agreed that these additional parameters would be collected during the next sampling event at the site.

5 - Groundwater Quality Evaluation 5.1 Detected Parameters Tables 6 and 7 present a summary of all analyzed parameters detected above the laboratory method reporting limits.

Lanc!ftll #2 At Landfill #2, barium was detected at 0.021 milligrams per liter (mg/l) in the GWB-4 sample. The maximum contaminant level (MCL) for barium is 2.0 mg/I. No organic parameters were detected during this monitoring event. There was insufficient water to collect samples from well GWC-3.

No parameters were detected in any of the field or laboratory QA/QC samples, and the laboratory QA/QC checks were within acceptable limits.

Lanc!ftll #3 At Landfill #3, barium was detected at concentrations below the MCL in the sample from well GWC-13 (0.043 mg/l). Zinc was also detected in well GCW-13 at 0.044 mg/l; there is no MCL for zinc. The Appendix II parameter mercury was detected at 0.0017 mg/l (MCL of 0.002 mg/l) in well GWA-7, and at 0.0004 mg/l in well GWA-15. In the sample from compliance well GWC-13, volatile organic compounds (VOCs) 1,1-dichloroethane, cis-l,2-dichloroethene and trichlorofluoromethane were detected at low levels, below MCLs where applicable. Trichlorofluoromethane was also detected in the GWA-7 sample; there is no MCL for trichlorofluoromethane. There was insufficient water to collect samples from well GWC-14.

No parameters were detected in any of the field or laboratory QA/QC samples, and the laboratory QA/QC checks were within acceptable limits.

5.2 StatisticalAnalYses In accordance with the approved Groundwater Monitoring Plan, statistical analyses were conducted for each constituent detected in the compliance well samples for this sampling event. The analyses were conducted to help identify any significant increase in constituent concentrations in 5

downgradient, or compliance, well samples over samples representative of background water quality.

The analyses were conducted consistent with U.S. EPA recommended methods as detailed in the guidance document "Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities -

Interim Final Guidelines" (1989) and the corresponding Addendum (1992).

The following methodology was used to evaluate the data:

• The distribution of the data was ftrst evaluated for normality using the Shapiro-Wilkes Test as recommended in the 1992 EPA guidance. The test indicates non-normal concentration distributions of the detected parameters in all wells at both landfills for either non-transformed or log-transformed data sets.

• For the well data sets at both landfills, the Kruskal-Wallis non-parametric analysis of variance method was used to compare the concentrations of individual parameters in each compliance well to the concentrations of these parameters in the background well. This method is recommended by the 1992 EPA guidance for non-normal sample sets that have between 15% and 90% non-detects.

The detailed statistical analyses are provided in Appendix C and the results are summarized below.

5.2.1 Landfill o

1. 2 At Landfill #2, barium was detected in the sample from compliance well GWB-4. The analyses do not indicate statistically signiftcant higher concentrations for this parameters in the compliance well samples compared to the concentrations in the background well sample. In addition, the barium concentration was below the MCL.

5.2.2 Landfill #3 Compared to background well GWA-15/MW-15, the analyses indicate statistically significant higher concentrations of the following parameters:

• Barium, 1,1-dichloroethane and trichlorofluoromethane in the GWC-13 well samples,

• Trichlorofluoromethane in the GWA-7 well samples, and

• Barium, 1,1-dichloroethane and cis-1,2-dichloroethene in the GWC-14 well samples.

The Appendix II parameter mercury was also detected in the GWA-7 and GWA-15 well samples in the December 2004 sampling event. Mercury was detected at 0.0017 mg/l (MCL of 0.002 mg/l) in well GWA-7 and 0.0004 in GWA-15. Statistical analyses of mercury concentrations were not performed since there are fewer than four data sets for mercury analysis to date in all wells.

It should be noted that the statistical analyses data sets include all sampling events to date for all wells. As a result, statistically higher concentrations of detected parameters in a well are determined based on all reported concentrations (including consideration of non-detects) from all sampling events for that well. If a concentration is lower in the current event for a well, the complete data set for the well may still indicate a statistically higher concentration over the background well data set considering all sampling events to date. For example, although there was no sample available for GWC-14 for this event, the statistical analyses indicate signiftcantly higher concentrations of barium, 1,1-dichloroethane and cis-1,2-dichloroethene for the GWC-14 historical sample data set.

- Conclusions Since a statistically significant increase over background is indicated for several analyzed parameters in wells GWA-7, GWC-13 and GWC-14 at Landfill #3, SNC will place a notice in the operating record within 14 days of submittal of this report as required by Chapter 391-3-4. The notice will indicate which constituents have shown statistically significant higher concentrations compared to the background wells.

SNC has now completed three rounds of Appendix II parameter sampling in wells GWC-13, GWC-14 and GWA-15, and found all Appendix II parameters with the exception of mercury to be below the analytical detection limit. Therefore, we will continue to perform analysis for the Appendix II parameter mercury in all wells during the regular semi-annual sampling events. To date, three rounds of analysis for mercury have been completed in wells GWC-5, GWB-6, GWA-7. After completion of four semi-annual sampling events for mercury in all wells, this parameter will be added to the routine statistical analysis that is currently performed for the Appendix I parameters.

A separate request will be submitted for approval to reduce the frequency of sampling for the other Appendix II parameters in wells GWC-13, GWC-14 and GWA-15, based on the lack of detection of these parameters in the previous assessment monitoring events and consideration of the factors listed in Rwe 391-3-4-.14, paragraph 26. SNC added annual monitoring for Appendix II parameters in well GWA-7 in December 2004. The next sampling event will include the Appendix II parameters that were inadvertently missed in well GWA-7 on the most recent monitoring event. Well GWA-7 will continue to be monitored annually for all Appendix II parameters unless the data warrant a reduction at which time an additional request for reduction will be submitted.
