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 analytical results for the semi-annual groundwater monitoring samples and annual Appendix II assessment monitoring samples taken in December 2003. As discussed in Sections 5 and 6 of the attached report, there was no statistically significant increase in the concentration of any detected parameter in the compliance well samples compared to the background well samples at Landfill #2. At Landfill #3 there was a statistically significant increase over background for barium, 1,1-dichloroethane and cis-1,2-dichloroethane in wells GWC-13/MW-13 and GWC-14/MW-14; chlorobenzene and 1A-dichlorobenzene in well GWC-14/MW-14 and trichlorofluoromethane in well GWC-13/MW-13. There was also a detection of mercury, an Appendix II parameter, in the sample from well GWC-14/MW-14. Statistical analyses of mercury concentrations were not performed since this was only the second analysis for this parameter. A copy of this letter and the attached report will be placed in the operating record within 14 days to serve as the notice to the operating record in accordance with EPD Solid Waste Rules 391-3-4. The next scheduled semi-annual sampling event is June 2004. In addition to the regular semi-annual monitoring for Appendix I parameters, all wells will continue to be analyzed for mercury. The next annual assessment monitoring for Appendix II parameters in wells GWC-13/MW-13, GWC-14/MW-14 and GWA-15/MW-15 will be conducted in December 2004.

1 - Introduction This report presents the results of groundwater sampling conducted in December 2003 at two private solid waste landfills (Landfill #2 and Landfill #3) operated by Southern Nuclear Operating Company, Inc. (SNC) at Plant Vogtle in Waynesboro, Georgia. Groundwater monitoring was initiated in 2002 in accordance with the approved Groundwater Monitoring Plan for the landfills. The landfills 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 landfills are operated under Solid Waste Permit #s 017-006D(L)(I) and 017-007D(L)(I). The active trench at Landfill #2 is used only for asbestos disposal. Landfill #3, permitted in 1987, has been utilized 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, Chapter 391-3-4, the September 1991 "Manual for Groundwater Monitoring" and the approved Groundwater Monitoring Plan for the landfills. The findings of the initial four sampling events, conducted from August 2002 through December 2002, and subsequent semi-annual sampling events were presented in reports previously submitted to the Department. This report presents the results of the December 2003 semi-annual detection monitoring sampling event and annual assessment monitoring. Subsequent reports will be prepared upon completion of semi-annual sampling 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 figures, 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 and GWC-ll/MW-

11. Well GWB-4/MW-4 is best characterized as a cross-gradient well, but is evaluated as a compliance well for this report. The well construction details are presented in Table 1.

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. As discussed in Section 3.2, well GWA-15/MW-15 is the designated background well, and the remaining wells are designated compliance wells. No surface water monitoring stations were present at the landfill at the time of the December 2003 sampling event. However, two new stormwater sedimentation ponds, constructed in accordance with the approved Design and Operational Plan, were completed at Landfill #3 after the December 2003

sampling event. It is anticipated that the surface water monitoring stations associated with the new sedimentation ponds will be sampled during the next semi-annual sampling event in June 2004. 3 - Groundwater Flow Rate and Directional Data 3.1 GeoloJ!l/HydrogeoloJ!l 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 conftnes the Tertiary and Cretaceous aquifers, the two conftned aquifers beneath the Plant site. The occurrence of groundwater underlying the landfills appears in conftned, semi-confmed, unconftned, 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 conftning 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 ftve 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 is frequently under semi-confmed or conftned 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 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 em/sec in GWB-6/MW-6 to 3.064 x 10.2 cm/sec in GWA-2/MW-2. Landfill #2 Depth to water measurements and groundwater elevations for the wells at Landfill 2 are presented in Table 1. Based on groundwater elevations measured during the sampling events to date, groundwater 2

underneath Landfill 2 trends from a relatively higher elevation at the eastern portion of the landfill (GWA-2/MW-2) to relatively lower elevations in the west to southwest direction beneath the landfill (Figure 1). Well GWC-ll 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-ll compared to wells GWA-2, GWC-3 and GWB-4. The hydraulic gradient (shown on Figure 1 for December 2003) was calculated using a three-point problem from potentiometric surface elevations in monitoring wells GWA-2/MW-2, GWC-3/MW-3 and GWB-4/MW-4. The hydraulic gradient has ranged from a minimum of 0.01 (October 2002) to a maximum of 0.08 Oune 2003). Landfill #3 Depth to water measurements and groundwater elevations for the wells at Landfill #3 are presented in Table 2. Based on the measured groundwater elevations to date, it appears 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 inf1ltration in the sandy soils within the 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. 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 16, 2003. Monitoring well GWA-15/MW-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 landf1ll. 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: Southeast: GWA-7/MW-7, GWC-13/MW-13, and GWC-14/MW-14; Northeast: GWB-6/MW-6, GWC-13/MW-13, and GWC-5/MW-5; and West-Southwest: GWA-7/MW-7, GWB-6/MW-6, and GWA-15/MW-15. The calculated hydraulic gradient is presented on the contour map (Figures 2). To date the steepest hydraulic gradient has been consistently to the north-northeast. The north-northeast trending gradient has ranged from a minimum of 0.08 (October and December 2002) to a maximum of 0.17 Oune 2003). 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 potable water rinse 3

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 entided "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 direcdy 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 3and4. 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 ParameterAna!yses 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 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 sufficiendy sensitive quantitation limits for comparison with maximum contaminant limits. Advanced Chemistry Labs, Inc., Adanta, 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 AppendixA. In addition, assessment monitoring was conducted at Landfill #3 for the December 2003 sampling event based on the results of previous detection monitoring events in which statistically significant concentrations of barium and several organic parameters were indicated in the GWC-13 and GWC-14 well samples. Mercury was also detected previously in the GWC-13 and GWC-14 well samples. Assessment monitoring consisted of analyses of the Chapter 391-3-4 Appendix II list of parameters for the GWA-15, GWC-13 and GWC-14 well samples, and mercury for all well samples. 5 - Groundwater Quality Evaluation 5.1 Detected Parameters Tables 6 and 7 present a summary of all analyzed parameters that were detected above the laboratory method reporting limits. 4

Lmdfil/#2 At Landfill #2, barium was detected at 0.022 milligrams per liter (mg/l) in the GWC-ll sample. The maximum contaminant level (MCL) for barium is 2.0 mg/I. The organic parameter trichlorofluoromethane was also detected at 6 micrograms per liter (ug/l) in the GWB-4 sample. There is no MCL for this parameter. No parameters were detected in any of the field or laboratory QA/QC samples, and the laboratory QA/QC checks were within acceptable limits. LJndfill#3 At Landfill #3, barium was detected at concentrations below the MCL in the samples from wells GWC-5, GWC-13, and GWC-14 and zinc was also detected in background well GWA-7, and wells GWC-5 and GWC-14. As shown in Table 7, a number of additional metals were also detected in the samples from GWC-5 and GWC-14. All detected concentrations were below the MCLs except for Mercury at 0.01 mg/l (MCL of 0.002 mg/l) and cadmium at 0.011 mg/l (MCL of 0.005 mg/l), both of which occurred in well GWC-14. It should be noted that the turbidity measured in wells GWC-5 (79.7 ntu's) and GWA-7 (100 ntu's) was significantly higher than in previous sampling events, and higher than the recommended maximum of 10 ntu's. In addition, well GWC-13 required 6 gallons of purging to reduce the turbidity below 10 ntu's compared to 1 to 2.5 gallons purged in previous sampling events. In GWC-14, there was insufficient water to facilitate sample collection using the low-flow pump assembly. The well was sampled using a bailer after purging the previous evening. No indicator parameters were measured during sampling of GWC-14 due to the lack of water in the well during purging. The increased detections of metals and VOCs in the wells during this sampling event is likely due to the increased turbidity in the wells, an indication that particles from the aquifer were suspended in the samples during collection. The VOCs 1,1-dichloroethane, and cis-l,2-dichloroethene were detected in the GWC-13 and GWC-14 samples. Chlorobenzene and 1,4-dichlorobenzene were also detected in the GWC-14 sample. Trichlorofluoromethane was detected in samples from GWA-7, and GWC-13. Xylenes were also detected in the sample from GWC-14. All of the detected VOCs were reported at concentrations below the MCLs, where applicable. No parameters were detected in any of the field or laboratory QA/QC samples, and the laboratory QA/QC checks were within acceptable limits. The Department collected split samples from wells GWC-5, GWC-13, GWC-14 and GWA-15 for VOCs and metals analyses. 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 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). 5

The following methodology was used to evaluate the data: The distribution of the data was first evaluated for normality using the Shapiro-Wilkes Test as recommended in the 1992 EPA guidance. The test indicates that the concentrations of the detected parameters in all wells at both landfills do not follow normal distributions. 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 wells. This method is recommended by the 1992 EPA guidance for sample sets that do not follow a normal distribution or that have between 15% and 90% non-detects. The detailed statistical analyses are provided in Appendix B and the results are summarized below. 5.2.1 Landfill #2 At Landfill #2, barium was detected in the sample from compliance well GWC-11/MW-11 and trichlorofluoromethane was detected in the GWB-4 well sample. The analyses indicate no statistically significant increase in the concentrations of these parameters in the compliance well samples as compared to the concentrations in the background well samples. 5.2.2 Landfill #3 Compared to background wells GWA-7/MW-7 and GWA-15/MW-15, the analyses indicate statistically significant higher concentrations of the following parameters: Barium in wells GWC-13/MW-13 and GWC-14/MW-14; 1,1-dichloroethane and cis-1,2-dichloroethene in wells GWC-13 and GWC-14; CWorobenzene and 1,4-dichlorobenzene in well GWC-14/MW-14; and Trichlorofluoromethane in well GWC-13/MW-13. The Appendix II parameter, mercury, was also detected in the GWC-14/MW-14 well sample at 0.01 mg/I. The MCL for mercury is 0.002 mg/I. Statistical analyses of mercury concentrations were not performed since this parameter was only analyzed for the second time as a component of assessment monitoring for this event. 6 - Conclusions Since a statistically significant increase over background is indicated for several analyzed parameters in wells GWC-13/MW-13 and GWC-14/MW-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 than in the background wells. The notice will also include detection of the Appendix II parameter, mercury, in well sample GWC-14/MW-14. SNC will continue assessment monitoring per the requirements of paragraphs (20) through (33) of Chapter 391-3-4-.14. Based on detection of the Appendix II parameter mercury during this sampling event, future semi-annual sampling will include analysis for mercury in all wells. In addition, the December 2004 sampling event will include the complete Appendix II analyses in wells GWA-15/MW-15, GWC-13/MW-13 and GWC-14/MW-14 to satisfy the assessment monitoring program requirement for annual Appendix II analysis in wells showing statistically significant increases of 6

baseline monitoring parameters. After completion of 4 semi-annual sampling events for mercury, this parameter will be added to the routine statistical analysis that is currently performed for the Appendix I parameters. 7

Where "Total" is entered, all species in the ground water that contain this element are included. \\4\\ CAS index are those used in the 9th Collective Index. \\5\\ Suggested Methods refer to analytical procedure numbers used in EPA Report SW-846 "Test Methods for Evaluating Solid Waste", third edition, November 1986, as revised, December 1987. Analytical details can be found in SW-846 and in documentation on file at the agency. CAUTION: The methods listed are representative SW-846 procedures and may not always be the most suitable method(s) for monitoring an analyte under the regulations. \\6\\ Practical Quantitation Limits (PQLs) are the lowest concentrations of analytes in ground waters that can be realiably determined within specified limits of precision and accuracy by the indicated methods under routine laboratory operating conditions. The PQLs listed are generally stated to one significant figure. PQLs are based on 5 mL samples for volatile organics and 1 L samples for semivolatile organics. CAUTION: The PQL values in many cases are based only on a general estimate for the method and not on a determination for individual compounds; PQLs are not a part of the regulation. \\7\\ This substance is often called Bis(2-chloroisopropyl)

ether, the name Chemical Abstracts Service applies to its noncorrunercial isomer,

Propane, 2,2[sec]-oxybis[2-chloro-(CAS RN 39638-32-9).
