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 samples taken in June 2003 and the first assessment monitoring at wells GWA-15/MW-15, GWC-13/MW-13, and GWC-14/MW-14 which was conducted concurrently with the regular semi-annual monitoring.

As discussed in Sections 5 and 6 of the attached report, there was a statistically significant increase over background for barium in wells GWC-13/MW-13 and GWC-14/MW-14; trichlorofluoromethane in well GWC-13/MW-13; and 1,1-dichloroethane, chlorobenzene and cis-1 ,2-dichloroethane in well GWC-14/MW-14. There was also a detection of mercury, an Appendix II parameter. in samples from wells GWC-13/MW-13 and GWC-14/MW-14. 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 Rules.

The next scheduled semi-annual sampling event is December 2003. In addition to the regular monitoring for Appendix I parameters, all wells will be analyzed for mercury based on the detection of mercury during this sampling event. The required annual assessment monitoring for Appendix II parameters will also be conducted in December for wells GWC-13/MW-13, GWC-14/MW-14 and GWA-15/MW-15.

1 - Introduction This report presents the results of groundwater sampling conducted in June 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 implemented at the landfills 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, were presented in the March 2003 Groundwater Monitoring Report. This report presents the results of the June 2003 semi-annual detection monitoring sampling event and assessment monitoring conducted based on the results of the initial detection monitoring events conducted in 2002. 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-11/MW-

11. Well G\VB-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 G\VB-6/MW-6 and G\VB-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.

Currently, there are no surface water monitoring stations at either landfill. Two surface water monitoring stations will be added upon construction of stormwater sediment ponds at Landfill #3 in accordance with the approved Design and Operational Plans for the landfills.

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 approximatdy 126 feet below land surface at the northwest boundary of Landfill #2 appears to have been completed just into or immediatdy 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 Usbon Formation with its uppermost unit, the Blue Bluff Marl, located immediately under the Utley Umestone. This marl layer, approximatdy 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 unconfined 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 is frequently 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 devations using an dectronic water-Ievd indicator. The water levd measurements were then subtracted from the appropriate measuring point elevations to determine groundwater devations in the wells.

Hydraulic conductivity (K) in the wells was measured on September 26, 2001. The values ranged from 5.634 x 1()-4 em/sec in GWB-6/MW-6 to 3.064 x 10-2 em/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 devations measured during the sampling events to date, groundwater underneath Landfill 2 trends from a relativdy higher elevation at the eastern portion of the landfill 2

(GWA-2/MW-2) to relatively lower elevations in the west to northwest direction beneath the landfill (Figure 1).

The hydraulic gradient (shown on Figure 1 for June 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. TIlls mounding effect is believed to be the result of natural infiltration in the sandy soils within the topographically high area in the center of the landfill. TIlls topographically high area, which encompasses a broad area within the landfill, is a natural site feature 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 during the June 2003 event.

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. TIlls well is therefore used as a background well to evaluate groundwater quality at the landfill.

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 gradient 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 were recorded in each well from the surveyed elevations using an electronic water level indicator. The water level indicator was decontaminated using a potable water and AlconoX wash and a potable water rinse

between use at each well. The water level measurements were then subtracted from the appropriate measuring point elevations to determine the groundwater elevations in the wells.

3

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 a QED SamplePro pump with dedicated replaceable pump bladders for each well. The wells were purged until a clear discharge was obtained with a turbidity of less than 10 NepWemetric Turbidity Units (ntu's). The purge rates were matched to the recovery rates of the wells, verified by periodic depth to water measurements to determine draw down during purging. The purging continued 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 on Tables 3 and 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 ParameterAnalYses 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 S). 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 601OB/8260B and 504.1 to provide sufficiently sensitive quantitation limits for comparison with maximum contaminant limits. All laboratory analyses were provided by Advanced Chemistry Labs, Inc., Atlanta, Georgia. The complete laboratory analytical reports, which include field and laboratory QA/QC results and chain-of-custody forms, are provided in Appendix A.

In addition, assessment monitoring was conducted at Landfill #3 for the June 2003 sampling event based on the results of the initial four sampling events in which statistically significant concentrations of barium and several organic parameters were indicated in the GWC-13 and GWC-14 well samples.

The 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.

Landftll#2 At Landfill #2, only zinc was detected at 0.029 mg/l in the GWC-11 well sample. Well GWC-3 could not be sampled for this event since it was dry.

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

Landftll#3 At Landfill #3, barium was detected at concentrations below the MCL in the GWA-7, GWC-13 and GWC-14 well samples. Zinc was also detected at low concentrations in the GWC-13 and GWC-14 well samples.

Several VOCs were detected in samples from wells GWC-13 and GWC-14, and the parameter trichlorofluoromethane was also detected in the sample collected from GWA-7. All of the detected VOCs were reported at concentrations below the MCLs. The number of detected parameters and the reported concentrations for the detected parameters decreased for this sampling event compared to the initial four sampling events conducted in 2002.

One assessment monitoring parameter, mercury, was detected in the GWC-13 and GWC-14 well samples at concentrations of 0.0005 mg/l and 0.0072 mg/l respectively. The MCL for mercury is 0.002 mg/l.

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).

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 concentration data sets 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. TIlls method is recommended by the 1992 EPA guidance for sample sets that do not follow a normal distribution and 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 Lam/fill #2 At Landfill #2, only zinc was detected in the sample from compliance well GWC-ll/MW-l1. The analyses indicate no statistically significant increase in zinc concentrations in the compliance well samples as compared to the concentrations in the background well samples at Landfill #2.

5.2.1 Lan4,fill #3 Compared to J:>ackground wells GWA-7/!vIW-7 and GWA-15/!vIW-15, the analyses indicate statistically significant higher concentrations of barium in wells GWC-13/MW-13 and GWC-14/MW-14, the organic parameter tricWorofluoromethane in well GWC-13/MW-13, and the organic parameters 1,I-dicWoroethane, cWorobenzene and cis-I, 2-dicWoroethene in well GWC-14/MW-14.

The Appendix II parameter, mercury, was also detected in the GWC-13/MW-13 and GWC-14/MW-14 well samples at concentrations of 0.0005 mg/l and 0.0072 mg/~ respectively. The MCL for mercury is 0.002 mg/l. Statistical analyses of mercury concentrations could not be performed as this parameter was analyzed for the first time as part 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 samples GWC-13/MW-13 and 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 2003 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 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.
