Dear Mr.Cown:

Pursuant to EPD Solid Waste Rule 391-3-4-.14 and in accordance with the approved Plant Vogtle Landtill#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 June 2005.Samples from all monitoring wells at Landfill#2 and Landfill#3 (with the exception of GWC-14)were analyzed for Chapter 391-3-4 Appendix I parameters. In addition, as a component of the assessment monitoring program for Landfill#3, samples from wells GWC-13, GWC-14 and GWA-15 were analyzed for Chapter 391-3-4 Appendix II parameters. 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 (SSI)over background for barium, 1, 1-dichloroethane and trichlorofluoromethane in13;trichlorofluoromethane in well GWA*7;and barium, 1, 1-dichloroethane and cis-1dichloroethene in well GWC-14.Mercury was not detected in any sampling wells during this sampling event;however, statistical analysis for mercury was performed because four complete data sets for mercury analysis have now been completed. There was not sufficient water to collect samples from GWC-14 in June 2005;however, the statistical procedure triggered 881s for this well based on prior detections of barium, 1, 1-dichloroethane and cis-1 ,2-dichloroethene. Carbon disulfide was detected in the newly installed well GWC-17;although there is no MCL for this parameter. EV-05-1677 Page 2 Georgia Environmental Protection Division Mr.Pete Cown Vogtle's Landfill#3 is currently the subject of a contamination assessment under a work plan approved by EPD on April 19, 2005.The results of this assessment will be submitted to EPD in a separate report.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.If you have any questions regarding this matter, please contact Mickey Perry at (205)992-6994.Sincere!r' ,(1. /J.M.Godfrey/7 Manager-Environmental A irs JMG/MEP:ahl cc: Mr.Michael Kemp (w/o)Mr.Earl Hinkle (w/o)Mr.Kurt Batsel (w/o)Attachment EV-05-1677 Page 3 Georgia Environmental Protection Division Mr.Pete Gown bc: T.E.Tynan (w/o)P.D.Rushton (w/o)N.J.Stringfellow (w/o)N.D.Dennis (w/o)G.L.Buck (w/o)D.G.Goodwin (w/o)(Return Receipt)SNG Document Management -Vogtle (Return Receipt) , Dextra September 6, 2005 Mr.Mike Godfrey Southern Nuclear Operating Company, Inc.40 Inverness Center Parkway p.G.Box 1295 Birmingham, Alabama 35201-1295

,-r 1-Introduction This report presents the results of groundwater sampling conducted in June 2005 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 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 findings 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 June 2005 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 nine permanent monitoring wells located along the perimeter of the wastemanagementunit 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 80 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 up gradient 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 nine permanent groundwater monitoring wells at Landfill#3 were installed in September 2001, July 2002 and June 2005.The well construction details are presented in Table 2.As noted in the table, well GWC-16 has been dry during each groundwater monitoring event.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.Wells GWC-17/MW-17 and GWC-18/MW-18 were recently installed at the southeast corner of the landfill as part of the contamination assessment program at Landfill#3.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-7/1-rW-7, it was decided to return to evaluating this well as a compliance well.This approach was used 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, GWB-16, GWC-17 and GWC-18 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 V ogde Landfill#3.As there was no discharge from either pond at the time of the June 2005 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 V ogde site consists of sedimentarydepositswithin 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 Udey 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 Udey Limestone. This marl layer, approximately 70 feet thick, is a near-impermeable layer that effectively confines the Tertiary and Cretaceous aquifers, the two confmed aquifers beneath the Plant site.The occurrence of groundwater underlying the landfills appears in confmed, semi-confmed, 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 sandi 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 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. 2 -I 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 to 3.064 x 10-2 em/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 0.015 (shown on Figure 1 for June 2005)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 Oune 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 infiltration 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.Asdiscussedpreviously, 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 June 13,2005.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: 3 ,-Southwest: GWB-6, GWA-7 and GWA-15;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 June 2005 event, the southwest gradient was 0.004, the northeast gradient was 0.08, and the southeast gradient was 0.12.The southwest gradient has typically been 0.01, with a maximum of 0.02 Qune 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 Qune 2003).The southeast gradient has ranged from a low of 0.06 (December 2002)to a maximum of 0.16 Qune 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 Alconoxwash 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 Teflonbladders.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 ill the field daily prior to use and at the conclusion of each sampling event.The field measurements are provided in 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 Alconoxsolution, 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.I 4.2 Parameter AnalYses 4 1 ,-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 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.Samples were also 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.Full Appendix II analysis was performed for wells GWC-13 and GWA-15 during the June 2005 event, and was scheduled for well GWC-14 but could not be performed as this well was dry.In addition, well GWA-7 was also sampled for the Appendix II parameter groups base neutral/acid extractables, cyanide and sulfide as these were inadvertently omitted from the GW A-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 June 2005 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.Landfill#2 At Landfill#2, barium was detected at 0.021 milligrams per liter (mg/l)in well GWA-2, 0.042 mg/l in GWB-4 and 0.034 mg/l in GWC-11.The maximum contaminant level (MCL)for barium is 2.0 rng/I.Zinc was detected at 0.029 mg/l in well GWB-4 and 0.034 in GWC-11.No organic parameters were detected during this monitoring event.No parameters were detected in any of the field or laboratory QA/QC samples, and the laboratory QA/QC checks were within acceptable limits.Landfill#3 At Landfill#3, barium wasdetectedat concentrations below the MCL in well GWC-13 (0.028 mg/D.Zinc was detected in well GCW-13 at 0.020 mg/l and in well GWA-15 at 0.029 mg/l;there is no MCL for zinc.In the sample from compliance well GWC-13, volatile organic compounds (VOCs)1,1-dichloroethane, cis-1,2-dicWoroethene and trichlorofluoromethane were detected at low levels, below MCLs where applicable. Carbon disulfide was also detected in newly installed well GWC-17;there is no MCL for carbon disulfide. There was insufficient water to collect samples from well GWC-14.No Appendix II parameters were detected.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 ,-5.2 Statistical AnalYses 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 FacilitiesInterim 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 either the Shapiro-Wilkes Test (for parameters with less than 50 samples)or the Shapiro-Francia Test (for parameters with greater than 50 samples)as recommended in the 1992 EPA guidance.The tests indicate that the concentrations of all detected parameters 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 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 LandJill#2 At Landfill#2, statistical analysis was performed for the two detected parameters barium and zinc.The analyses do not indicate statistically significant higher concentrations for these parameters in the compliance well samples compared to the concentrations in the background well sample.5.2.2 Lanqfill#3 At Landfill#3, statistical analysis was performed for the six detected parameters barium, zinc,dichloroethane, carbon disulfide, cis-1,2-dichloroethene, and trichlorofluoromethane. Although mercury was not detected in any wells during this event, statistical analysis was also performed for mercury at Landfill#3 because mercury was previously detected at Landfill#3 and the June 2005 event reflected the first time that 4 full sample result sets were available to perform the statistical analysis.In the future, statistical analysis for mercury will only be conducted if this parameter isdetectedduring the monitoring event.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.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 6

--considering all sampling events to date.For example, although there was no sample available for GWC-14 for this event, the statistical analyses indicate significantly higher concentrations of barium, 1,1-dichloroethane and cis-1,2-dichloroethene for the GWC-14 historical sample data set.6-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-13,14 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.Based on the lack of detection of any other Appendix II parameters in wells GWC-13, GWC-14 and GCW 15, a request was submitted to EPD on April 5, 2005 for approval to reduce the frequency of sampling for the other Appendix II parameters at Landfill#3.However, as Landfill#3 is the subject of a contamination assessment pursuant to a work plan approved by EPD on April 19, 2005, SNC issued a letter on April 5, 2005 withdrawing the Appendix II reduction request pending evaluation of the assessment results.The results of the CA will be submitted in a separate report.7 ,-1 TABLES )Table 1 Southern Nuclear Operating Company Plant Vogtle Landfill#2 Groundwater Elevations and Monitoring
