l FSV FINAL SURVEY REPORT BACKGROUND INFORMATION O VOLUME 6 - SURVEY GROUP E

1.0 BACKGROUND

INFORMATION Volume 6 of the Final Report includes the results of final survey for Survey Group E. This  ! group generally includes open land areas, irrigation ditches, storage and evaporation ponds and basins and other related areas which make up the Effluent Discharge Pathway located both within and outside the Restricted Area. The Release Records for Survey Areas comprising Group E are divided into two parts: Book One and Book Two. The Survey Areas contained in Survey Group E were generally expected to be classified as Affected for final survey planning purposes. During decommissioning activities or through funher investigation of system histories and/or initial final release or characterization surveys, the following information was ascenained: The Liquid Effluent Pathway (LEP) from the discharge point, was composed of the Goose Quill Ditch, the Jay Thomas Ditch, the Farm Pond and the outfall to the South Platte River. The Goose Quill Ditch was a concrete-lined culven (ditch) approximately 7000 feet in length, which began at the effluent discharge point west of County Road 19%, and terminated at the Jay Thomas Ditch. The Goose Quill Ditch was approximately 5 feet wide at the top and one foot wide at the bottom, with sloping sides of approximately 40 inches each. The Jay Thomas Ditch was a stream bed beginning g upstream of the intersection with the Goose Quill Ditch and termirating a: the Farm () Pond. The Jay Thomas Ditch was unlined and was 3-6 feet wide,2-3 feet deep and approximately 2300 feet long. The Farm Pond covered approximately 25 acres and was 2-4 feet deep. The outfall of the pond was a stream bed that eventually terminated at the South Platte River. Water from the Goose Quill Ditch and the Jay Thomas Ditch was routinely divened for agricultural irrigation of the surrounding fields and pastures. Prior to 1994 the Goose Quill Ditch was known to leak water into various adjacent soil areas which provided means for transport of radioactive materials to the surrounding soil. In addition, the ditches were periodically cleaned of vegetation and sediment in order to maintain required flow rates and avoid overflow. The removed material was routinely deposited on the banks immediately adjacent to the ditches, i i 1-1 Revision 0 l

FSV FINAL SURVEY REPORT DECOMMISSIONING ACTIVITIES VOLUME 6 - SURVEY GROUP E 2.0 DECOMMISSIONING ACTIVITIES A review of analysis results for liquid wastes released from FSV indicates that these releases were well within the requirements of Public Service of Colorado's Offsite Dose Calculation Manual (ODCM). Compliance with the ODCM, and the Radiological Environmental Monitoring Program (REMP) demonstrated that the total dose from liquid effluents was maintained at less than 3 mrem / year. Late in the summer of 1993, ODCM calculations yielded slightly increased doses. This initial concern prompted the collection of a sediment sample from the inlet to the Farm Pond on 9/29/93. The analysis results of this sample indicated a concentration that was greater than those reported by both the Initial Radiological Site Characterization surveys performed during 1992, and by PSCo's Radiological Environmental Monitoring Program. Although the result was below that which would impact the final survey, a potential increase in the radioactivity concentration was indicated. Sediment and soil samples have been periodically collected since 1993 to check for buildup of radioactive materials. Additionally, in-situ gamma spectroscopy measurements were collected along the liquid effluent pathway, in agricultural dispersion areas, and in areas around and beyond the farm pond. Indications of cobalt-60 and europium radionuclides demonstrated that these radionuclides were present at some locations. In January 1995, a formal characterization survey plan was developed for the areas surrounding , the LEP, and approximately 750 environmental (sediment and soil) samples were collected between 2/95 and 4/95. The intent of the survey was to define the bounds of the areas of l increased concentrations,within the effluent pathway and surrounding areas. Samples were  ! collected in accordance with approved operating procedures designed to meet final survey quality ' requirements. Final Survey Procedures were not used and statistical analyses were not l performed on the resulting data because the samples would not represent the final condition of ' the pathway and this characterization survey was considered to be a part of the planning for the initial final survey. The results from more than one thousand environmental samples collected over the past two years of the decommissioning as a part of the characterization and follow-up characterization surveys have shown that any increased concentrations of radioactive material are present in very localized areas, and are decreasing due to radioactive decay and the effects of weathering. The bounds of these areas are well-defined, and have been previously selected for biased sampling. The areas of i? creased concentration peaked at their highest concentration at the beginning of 1995, and have been identified by the characterization to be located where: 2-1 Revision 0 l

1. Dredged materials had been removed from the ditches and placed on the banks of the ditches;
2. The ditches have leaked or overflowed and drained into slough or field areas, or;
3. In the early days of the decommissioning project, irrigation may have occurred during dischargu or dredging operations.

As a result of the characterization surveys, controls were implemented which included the installation of additional water-processing equipment and all discharges have been made at concentrations (prior to dilution) that were below the LLD's required by the ODCM. The target concentrations for cesium-137 and cobalt-60 were 2E-07 and 1E-07 pCi/ml, respectively. Additionally, the following controls were implemented: Results of radiological analysis were reviewed and accepted by the SEG Project Radiation Protection Manager prior to releasing water. The Goose Quill ditch was inspected for leaks and repaired where necessary. The ditch was walked down while in full dilution flow prior to a release to inspect for overflow and g leaks. V' Dredging materials from the ditch were sampled and placed in a designated storage area for control and disposition. Irrigation from the ditches was not permitted during discharges or dredging operations. The last liqua .scharge via the liquid effluent pathway was completed on 7/3/96. During the I week of 7/22/90, the Goose Quill was sampled for radiological and non-radio'ogical constituents. Subsequent to collection of these samples, dilution water was diverted from the Goose Quill, and the fmal survey was performed, l l i l

FSV FINAL URVEY REPORT SURYEY FINDINGS VOLUME e SURVEY GROUP E 3,0 SURVEY FINDINGS Summary results of the Final Surveys for Group E Survey Areas and Survey Units are presented in Table 3.1. Individual Release Records for Group E Sun'ey Areas are presented in Section 6.0 of this Volume. Because of the large areas involved and the significant characterization data that has been obtained, a special survey plan for the Liquid Efnuent Pathway was developed. This plan is described in Technical Basis Document (TBD) No. 209 and was submitted for NRC approval on September 11,1996 (PSCo Letter P-96060). Key features of this specifically developed plan included dividing the area into three survey classifications, based on the potential for contamination and reducing sample frequencies, survey frequencies and scan requirements accordingly. A summary of the final survey measurement results for all Group E Survey Areas submitted with this report is presented in Table 3.1 and 3.2, " Summary Results of Individual Survey Areas - Group E". The Tables provides values for each of the primary types of measurements collected within each Survey Area (i.e., Total Surface Activity and Removable Surface Activity, Exposure Rate and Concentrations in Soil and/or Water). For each type of measurement collected, the total number of measurements, the maximum value (Maximum Value for TSA and RSA or Sum of Fraction of GLV for Soil Samples) and the maximum Upper Confidence Limit (UCL) of the Mean values are provided. if applicable. Individual measurement results, for Survey Units within a specific Survey Area, are presented at the end of this Volume within the respective Survey Area Release Records. For Group E,3.228 individual measurements representing final survey results were recorded. Additional measurements were obtained but only these 3.228 represent the final reported measurements which justified the conclusion that the Survey Areas met the release criteria for unrestricted use. Total Surface Activity measurements comprised 1,020 of the 3.228 total measurements. Removable Surface Activity measurements comprised 1.020 of the total measurements. Exposure Rate measurements comprised 340 of the total measurements. Measurements of concentrations of licensed radionuclides in soil comprised 837 measurements. Measurements of concentrations of licensed radionuclides in water comprised 11 measurements. 3-1 O

the respective Survey Unit classification. The Critical Izvel (L ) and Minimum Detectable Activity (MDA) for Total Surface Activity measurements were reported in two ways within the Release Records. On the Statistical . Summary page, the reported Minimum Detectable Activity value was the value which represented the " highest / greatest" Minimum Detectable Activity value from multiple download reports for the Survey Unit. The Critical Level reported was the corresponding Critical Izvel value for the reported Minimum Detectable Activity. On the Corrected Field Activity Values page(s), Critical level values were calculated for each individual download report. Values i exceeding the Critical Level for the specific download report are underlined. All Removable Surface Activity results were wc!! below the Removable Surface Activity GLV of the SGLV of 750 dpm/100 cm2 for an Affected Survey Unit. [^ The Critical Level (L,) and Minimum Detectable Activity (MDA) for Removable Surface Activity measurements were reported in two ways within the Release Records. , On the Statistical Summary page, the reported Minimum Detectable Activity value was either the value which represented the Minimum Detectable Activity for all removable activity smears within a Survey Unit counted on that day, or it represented the " highest / greatest" Minimum Detectable Activity value from multiple days of counting removable activity within a Survey Unit. The Critical Level reported was the corresponding Critical Level value for the reported Minimum Detectable Activity. On the Corrected Field Activity Values page(s), Critical Level values were calculated for all removable activity smears within a Survey Unit counted each day. Values exceeding the Critical Ixvel for the specific download report are underlined. 1 l Exposure Rate measurements indicated that no Survey Area " Maximum Survey Area Values" were in excess of the Exposure Rate Release Limit of 10.0 pR/hr for an individual measurement, and the average expasure rate did not exceed 5.0 R/hr when averaged over 100 square meters

for open land areas.

Concentrations in soil and water indicated that no sample result exceeded the concentration guideline value detailed in FSV-FRS-TBD-209, " Final Survey Requirements for the Liquid  ; Epluent Pathway". ' 3-2

Goose Quill Ditch Survey Package ID: E0001 Survey Package

Description:

Effluent Pathway - Goose Quill Ditch This Survey Area was the concrete section of the Effluent Pathway - Goose Quill Ditch. The Goose Quill Ditch is 1,800 meters in length and was a major portion of the Liquid Effluent Pathway. The ditch begins at the discharge pipe and terminates at the Jay Thomas Ditch. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0001 included the following: Equipment / Components Systems None None /N Q The concrete surfaces of this area were surveyed as a Suspect, Affected Survey Unit. Survey Measurements locations were la'oeled every five meters down the center of the ditch bottom and on each side of the ditch at the approximate water level. Measurement locations were marked on survey maps, survey location tables and/or survey instructions to designate where measurements have been collected.. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classification / Surface Category Survey Medium Description Non-Suspect Affected Lower Walls Bare Exterior Concrete and E0001BE00lG3 and Floors - Exterior Sediment Survey Area Operational IIistory: The Effluent Pathway - Goose Quill Ditch was in operation prior to August 18,1989. The ditch was 1,800 meter in length and was a major part of the Liquid Effluent Pathway. The Liquid Effluent Pathway was used to transfer radioactive discharge liquids from the Fort St. Vrain site to the St. Vrain River. Liquid releases made before 1993 were listed in the Public Service Company's Annual Eftluent Release Reports. Radioactive comamination was identified in this o area during the Effluent Pathway Characterization Survey. U Page 2

I Survey Area Decommissioning and Remediation Activities: Apart from extensive characterization surveys, no decommissioning or remediation activities O were performed in this area. Previous surveys conducted along the Liquid Effluent Pathway included the following: The Radiological Environmental Program implemented by Colorado State University for Public Service Company of Colorado.

  • Investigations performed by SEG between September 1993 and November 1994.
  • A Scoping Survey performed by SEG between November 1994 and January 1995.
  • A Follow-up Survey performed by SEG during May and June 1996.

Soil and vegetation samples collected in this Survey Area during the January 1995 Effluent Pathway Characterization surveys indicated cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137), and europium-152 (Eu-152). Non-gamma analyses indicated activity of 9.39 to 26.8 pCi/g iron-55 (Fe-55).

No other decommissioning or remediation activities were performed in this area. O l l Page 3 i

i . i i . Isolation and Control Measures: I2 vel 1 Controls  ; k Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned  ! l personnel regarding final survey isolation and control measures. j

!       No use, storage or movement of radioactive material was permitted in this Survey Area after                   ;

initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engmeer trSLE). Radioactive material moved to i this area was not permitted to have removable surface activity greater than 250 dpm/100 cm2 , The configuration of the Effluent Pathway - Goose Quill Ditch during final survey activities remained basically the same as the configuration during operations. t i

 ;      The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required                      i notification of the Technical Project Supervisor (TPS) and the Final Survey Operations                        :

Supervisor (FSOS) and the approval of PSCo. l Survey Area

Conclusions:

f i  ! The results of the total and removable surface activity measurements and the concrete and sediment samples collected within this Survey Area meet the criteria for release for unrestricted i use. ' O Survey Area

Survey Design: Measurement Type No. of Measurements Description O , Scanned the bottom and at the watet line on the Beta Scan N/A sides of the accessible ditch surfaces. No areas of elevated activity were identified. 1,020 Collected 3 total surface activity measurements at Total Surface each flag location, I at the bottom and I on each Activity side of the ditch at the water line. 1,020 Collected smears at the same survey measurement Sy Smears locations as the total surface activity measurements. Initially collected 5 sediment samples West of the culvert, identified as section B, under survey Sediment 1 cation code E000lLZ00lG3T02. 22 During investigation collected an additional 17 sediment samples from section B under survey location code E0001LZ00lG3G01. Collected five concrete samples at SMLs 20,137, Special Samples 5 354, 672, and 1073 under survey location code E000iLZ002G3TO1. Survey Unit Investigations: Investigation No. 1 09/24/96 O Sediment samples obtained in Section B of the Goose-Quill ditch indicated activity due to licensed material above MDA. This portion of the Liquid Effluent Pathway (LEP) was not cleared of debris, and only sediment samples were collected since this portion of the LEP was not used for discharge and residual activity was not anticipated. The source of the contamination could have been a small amount of leakage through the dam installed to isolate Section B from the balance of the LEP. The RC sample numbers for the 5 sediment samples are 14.00333, 14.00334,14.00335,14.00336, and 14.00337. The 5 samples were collected using location code E0001LZ00lGZT02. The samples were obtained for the purpose of determining iflicensed material was present in Section B of the LEP. Based on the levels of activity found in Section B of the Goose-Quill ditch, an investigation survey was performed to obtain additional samples in order to define the bounds of the residual activity. The additional samples were obtained at approximately 10 meter intervals, beginning 20 meters after the last sample location from the Initial Final Survey (i.e. SML 5), and ending where the ditch turns south (approximately 160 meters). Sediment samples were obtained and the sample analysis type utilized was " LAB 06 - gamma analysis" The sample results were i reviewed to determine the extent of the contamination. Seventeen additional sediment samples were obtained during the Investigation Survey, and support the understanding that small amounts of residual activity are limited to the area immediately adjacent to the dam installed to isolate Section B from the balance of the LEP. Page 7 i

Survey Unit Investigations: (continued) 10 V Eleven of the additional seventeen samples exhibited no licensed material (i.e. 0.00 pCi/g or < MDA), and six of the samples indicated only background levels of Cs-137 ranging from 0.05 to 0.14 pCi/g. As a comparison, normal activity levels for Cs-137 in surface soil is approximately 0.12 pCi/g. The above sediment sample results demonstrate that the licensed material activity identified during the Initial Final Survey was isolated to that area immediately west of the dam installed l to isolate Section B from the balance of the LEP. The sediment and debris was not removed from Section B since the licensed material concentrations were well below the established Site Guideline Values. Total and removable surface activity measurements within Section B were not required for Section B since no elevated activity was discovered during the Initial Final Survey for the balance of the Goose Quill ditch where sediment sample concentrations were consistent with the sample results from the sediment storage area (Survey Package E0014). The sediment storage area had a mean sum of fractions of 0.09 (maximum of 0.51) and the mean sum of fractions for Section B was .08 (maximum 0.61). No additional soil samples were required for the banks of Section B since dredging operations did not occur along this portion of the LEP. No further action was required. ' (vD Page 8

Description:

Goose Quill Ditch Banks , The Goose Quill Ditch Banks were the upper dirt portion of the Goose Quill ditch, which was a major portion of the Liquid Effluent Pathway. The Goose Quill Ditch was a concrete ditch which began at the plant effluent discharge pipe and terminated at the Jay Thomas Ditch. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0002 included the following: l Equignent/ Components Systems )) None None I The unpaved surfaces of this area were surveyed as an Affected Survey Unit. The Affected q Survey Unit was not gridded. Measurement locations were marked on survey maps and/or Q survey instructions to designate where measurements were collected. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classification / Surface Category Survey Medium Description E0002LZ00lGI Affected Open Land Area Surface Soil l Survey Arra Opemtional History: The Goose Quill Ditch Banks were in operation prior to August 18, 1989. The ditch banks comprised the upper portion of a 1,800 meter long ditch which was a major part of the Liquid Effluent Pathway. The Effluent Pathway was used to transfer radioactive discharge liquids from the Fort St. Vrain site to the South Platte River. Liquid releases were listed in the Public Service Company's Annual Effluent Release Reports.

Survey Area Decommissioning and Remediation Activities: Apart from extensive characterization surveys, no decommissioning or remediation activities O were performed in this area. Previous surveys conducted along the Liquid Effluent Pathway included the following: The Radiological Environmental Program implemented by Colorado State University for Public Service Company of Colorado. Investigations performed by SEG between September 1993 and November 1994. A Scoping Survey performed by SEG between November 1994 and January 1995.

  • A Follow-up Survey performed by SEG during May and June 1996.

Soil and vegetation samples collected in this Survey Area during the January 1995 Effluent Pathway Characterization surveys indicated cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137), and europium-152 (Eu-152).

isolation and Control Measures: level 1 Contrcls (~'\ O Prior to the Onal survey of Group E Survey Areas, training sessions were held with site assigr.ed personnel regarding final survey isolation and control mcasures. No use, storage or movement of radioactive material was permitted in this Survey Area after initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). Radioactive material moved to this area was not permitted to have removable surface activity greater than 250 dpm/100 cm 2, The configuration of the Goose Quill Ditch Banks during final survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required notification of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo.

Survey Design: (continued) Total surface activity measurements and removable surface activity measurements were not required l'or this Survey Unit. Of the 50 samples required for this survey package,40 were biased sample locations based on the Characterization and Follow-up surveys and 10 were non-biased sample locations based on sample distribution. The QC surface soil sample results are displayed on the Activity Graph, but are not included in the summary statistics for the survey unit. Survey Unit Investigations: Investir.ation No.1 09/18/96 The results of the Initial survey for survey unit E0002LZ00lGZT01/Q01 indicated five soil sample concentration results in excess of 25% of the concentration SGLV. The elevated sample numbers include SMLs 22,25,29,30,and 40. The results were as follows: SML# Fraction of Concentration SGLV 22 0.4094 25 0.8598 (Q01) 29 0.2622 30 0.2713 40 0.5049 No other samples were e?.evated. Instructions were written and a sub-package was issued to perfonn investigation surveys. Gamma scans were performed over each of the 10 meter by 10 meter grids bounding the points of elevated activity and gamma exposure rate measurements were obtained using the MicroSpec-2 at 1 meter from the surface of each surface soil sample location. Surface (coded LZ001) and sub-surface (coded LS001) soil samples were obtained at each point of elevated activity identified during the initial survey and collected surface soil samples at the center each of the 3.3 meter by 3.3 meter grids formed by the 10 meter by 10 meter grid area. Two additional soil samples were obtained (SMLs 93 and 94). Sub-surface soil samples totaled 5 at SMLs 88-92 and surface soil samples totaled 39 at SMLs 51-87,93 and 94 for investigation no.l. For gamma exposure rates, a total of 39 measurements were collected with the MicroSpec-2 at the same locations as the surface soil samples. The results of the investigation surface soil samples Sum of Fractions (SOF) of GLV and respective exposure rate measurement were as follows : Surface Soil Sample Results Initial Initial Investication Investication Investication SML# SOF of GLV _SJiL# SOF of GLV Exposure Rate (uR/hr) 22 0.4094 52 0.0171 3.3 25(QC) 0.8598 61 0.533 4.4 29 0.2622 71 0.178 3.3 30 0.2713 70 0.589 3.9 40 0.5049 80 0.439 3.3 Page 8

The resulting Sum of Fractions (SOF) of GLV for the surface soil sample and respective exposure rate measurement for SML 94(located within the adjacent grid block to SML 40) were 1.01 and 6.luR/hr. The exposure rate measurement does not exceed the single measurement GLV of 10 uR/hr, but the SOF of GLV licensed radioactive material concentration in soil does exceed the GLV of (1).

Survey Unit Investigations: (continued) O Along the banks of Goose-quill Ditch a 100% gamma scan was performed on both sides of the goose-quill ditch (including the west branch shown on the map). Several points were identified and marked accordingly. The scan encompassed an area 3 meters wide on both sides of the ditch as measured from the edge of the concrete outward on each of the banks. Additional soil samples were collected as described in Investigation #2. No samples were obtained as part of this sub-package for the areas identified during the gamma scan of both sides of the goose-quill  ; ditch, i This survey unit will be reclassified as "Gl" based on the results obtained above and the measurement and sample results obtained during investigation no.1 will be used for reporting purposes. Investigation No.2 09/25/ % The results of the Investigation No.1 gamma scan survey along the banks of the Goose-Quill ditch indicated gamma exposure rates in excess of the specified action level of 30 pR/hr. Seven areas have been selected to obtain surface soil samples and one meter exposure rate  ; measurements. The areas of elevated exposure rates are as follows-  : I Flan # Scan Exposure Rate (uR/hr)  ; 36 30-36 82-83 30-35 O 218-219 225-226 31-34 32-34 245 35 249 31-35 1 257 32-40 Additionally, elevated readings were noted in an additional irrigation ditch which is located adjacent to the north side of the Goose-Quill ditch between Irrigation Ditch 2 and 3. Instmetions were written and a sub-package was issued to perform investigation surveys at each . of the elevated areas identified while performing investigation no.1 surveys and the additional irrigation ditch. A scan survey of the elevated area and the irrigation ditch was performed and a surface soil sample and a one meter exposure rate measurement, using the MicroSpec-2, were collected at the highest point identified by the scan. The SML numbering began with SML 95 and ended with SML 107, and all samples and measurements used survey reason code "G02 - Investigation". l I 1 O

See investigation no.3 for further detail. Investigation No.3 10/10/96 The results of the gamma scan survey required as described in Investigation #2, for survey unit E0002LZ00lGIT01, indicated several elevated exposure rates. Of these,13 of the most elevated were selected to collection of soil samples. Four of the additional soil concentration sample results were in excess of the SGLV. The elevated sample numbers include SMLs 95,100,101, and 103. Sample location 102 was not above the limit, however, the location was within 5 meters of SML 103 and the concentration value approached 1.0 unity. The results were as follows: SML# Fraction of Concentration SGLV 95 2.9 100 2.25 101 2.94 102 0.926 103 1.63 No other samples were elevated. O Page 11

l l l Survey Unit Investigations: (continued) A b Subsequent to performance of Investigation No.1 and No.2, this survey unit was reclassified as Gl" affected opened land area. Instruction were written and a sub-package was issued to collect exposure rate measurements using the MicroSpec-2 at 1 meter from the same locations as the initial surface soil samples, and QCs, as well as gamma scan, collect surface and sub-surface soil samples and exposure rate measurements within the investigation no.2 area. The MicroSpec-2 measurements were collected at I meter from the initial soil sample survey locations (SMLs 1-50). This was added due to reclassification and was noted that the soil samples were obtained prior to obtaining the MicroSspec-2 measurements. The initial SML numbers were used and survey reason code "G03 - Investigation". The exposure rate measurement results for SMLs 1-50 ranged from 0.0 uR/hr to 6.1 uR/hr at SML 6. Only one other SML exceeded 5.0 uR/hr, this was SML 34 which measured 5.6 uR/hr. The exposure rate measurement results for six other SMLs were equal to 5.0 uR/hr, these SMLs were 3,4,11, 12,16 and 30. The respective radionuclide concentrations in soil sum of fraction (SOF) of GLV were evaluated and the sample results were as follows : Surface Soil Sample Results bilia.J Investication SML# SOF of GLV Exposure Rate (uR/hr) 3 0.1655 5.0 4 0.0744 5.0 t O 6 0.0285 6.1 11 0.0000 5.0 12 0.0000 5.0 16 0.0000 5.0 30 0.2713 5.0 34 0.0000 5.6 The application of the medium code G9994 for exposure rate resulted in a conservative estimate of the exposure rate due to licensed radioactive material. The radionuclide concentrations in soil sum of fraction (SOF) of GLV were evaluated and the sample results were significantly less than the GLV of (1). The exposure rate measurement results equal to 5 uR/hr, SMLs 3,4,11,12, 16 and 30, and the measurement results in excess of 5 pR/hr at SMLs 6 and 34 were not due to licensed radioactive material, but were due to naturally occurring radionuclides in the environment. Investigation Areas (SMLs 95,100 and 101): A 100% gamma scan over each of the 10 meter by 10 meter grids bounding the points of elevated activity was performed and an exposure rate measurement using the MicroSpec-2 at I meter from the surface at each surface soil sample location was collected. Surface and sub-surface soil samples (6-12 inch) were collected at each location of elevated activity identified during the investigation no.2 survey and a surface soil sample collected at the center each of the 3.3 meter by 3.3 meter grids formed by the 10 meter by 10 meter grid area.

Survey Unit Investigations: (continued) The resuhs of the soil samples and exposure rate measurements for the investigation survey area O around SML 95 weic as follows: Sample Concentrations for Weichted Calculation of the Mean SML# Exposure Rate (uR/hr) Sum of Fraction of GLV 95 3.3 2.90 109(location 95) 3.9 1.30 108 2.2 0.0107 110 1.1 0.0594 111 1.7 0.00 112 2.2 0.00 113 0.6 0.0034 114 0.0 0.00 115 0.0 0.00 116 1.7 0.00 Weichted Mean: 0,32 Sub-Surface Sample Concentrations SML# Exposure Rate (uR/hr) Sum of Fraction of GLV 117 (location 95) not required 0.189 The investigation survey effectively bounded an area of approximately 100 square meters within the vicinity of the initial SML 95, and the measurement and sample results effectively demonstrated that only one location exceeded the concentration SGLV. The area of the investigation area was a standard 10 meter by 10 meter area. To arrive at a conservative estimate of the weighted mean for residual concentrations, all samples used in the calculation were obtained from the 10 meter by 10 meter grid about SML 95 (excluding SMLs 109 and 117). The 4 samples collected from the banks (SMLs 108,109,110 and 117) confirmed our understanding that the majority of the residual activity was confined to the banks of the ditch, and the residual activity in the pasture land adjacent to the ditch had been adequately characterized. The resulting weighted mean " sum of fractions" including the elevated area at SML 95 was less than one (0.33). The results of sediment soil samples collected within this investigation area meet the criteria for release for unrestricted use. O Page 13

Survey Unit Investigations: (continued) t' b Investigation Areas (SMLs 102 and 103): A 100% gamma scan of the banks adjacent to SMLs 102 and 103, extending out (north and south) approximately 3 meters was performed. The bounds of the investigation schnned area overlapped approximately 5 meters east of SML 103 to 5 meters west of SML 102. An exposure rate measurement using the MicroSpec-2 at I meter from the surface at each surface soil sample location was collected. Surface and sub-surface soil samples (6-12 inch) were collected at SML 102 and 103 and a surface soil sample collected at approximately 1 meter intervals effectively bounding the initial SMLs 102 and 103. Four surface samples were collected from the banks bounding SMLs 102 and 103 (two on the north and two on the south side). The results of the soil samples and exposure rate measurements for the investigation survey area around SMLs 102 and 103 were as follows: Sample Concentrations for Weighted Calculation of the Mean SML# Exposure Rate (uR/hr) Sum of Fraction of GLV 147(location 102) 3.3 1.44 103 5.0 1.631 138 1.7 0.445 139 2.2 0.290 140 2.2 0.486 O 141 3.3 0.736 O 142 2.8 0.497 143 1.7 0.493 144 2.8 0.450 145 3.3 0.508 Weichted Mean: 0.91 Sub-Surface Sample Concentrations SML# Exposure Rate (uR/hr) Sum of Fraction of GLV 148 (location 102) not required 0.112 149 (location 103) not required 0.0446 The investigation survey effectively bounded an area of approximately 100 square meters within the vicinity of the SML 102 and 103, and the measurement and sample results effectively demonstrated that only two locations exceeded the concentration SGLV. The area of the investigation area was not a standard 10 meter by 10 meter area since the ditch is irregularly shaped, and SMLs 102 and 103 were obtained from the bottom of the ditch. The I length of the investigation area was approximately 33 meters along the ditch,9 meters upstream i of SML 103,15 meters between SMLs 102 and 103 and 9 meters downstream of SML 102. l The width of the investigation area varied from 3 meters to 9 meters with the widest dimension ) at SMLs 102 and 103. Page 16

Survey Unit Investigations: (continued) To arrive at a conservative estimate of the weighted mean for residual concentrations, all O samples used in the calculation were obtained from the bottom of the ditch, rather than locations designated by superimposing a 10 meter by 10 meter grid across the ditch at each SML (102 and 103). These locations were most likely to contain residual activity, since the activity is known to have originated from the interior of the ditch. The resulting weighted mean " sum of fractions" including the elevated area at SMLs 102 and 103 was less than one (0.91). The results of sediment soil samples collected within this investigation area meet the criteria for release for unrestricted use. The 4 samples collected from the banks (SMLs 150-153) confirmed our understanding that the majority of the residual activity is confined to the interior of the ditch, and the residual activity in the pasture land adjacent to the ditch had been adequately characterized The results of the soil samples and exposure rate measurements for the banks about the investigation survey area around SMLs 102 and 103 were as follows: Spjnp]e Concentrations for Weichied Calculation of the Mean SMI, # Exposure Rate (uR/hr) Sum of Fraction of GLV 150 3.3 0.0160 151 3.3 0.00615 152 1.1 0.0146 153 3.3 0.00 To further evaluate the elevated results, the 2 samples collected from the banks adjacent to each of the elevated locations were averaged and assumed to represent the concentrations that would have been found within the non-elevated population of each of the 10 meter by 10 meter grids superimposed across the ditch, and containing the elevated locations. For determination of the value to apply within the 10 square meter grid blocks on the east and west sides of SMLs 103, averaging of SMLs 150 and 153 was required. For determination of the value to apply within the 10 square meter grid blocks on the east and west sides of SML 102, and averaging of SMLs 151 and 152. The weighted means for residual concentrations within each of the 10 meter by 10 meter areas surrounding SMLs 102 and 103 were then calculated. O 1 Page 17

Survey Unit Investigations: (continued) \ The results of the soil samples and exposure rate measurements for the investigation survey area around SML 102 were as follows: Sample Concentrations for Weighted Calculation of the Mean SML# Exposure Rate (uR/hr) Sum of Fraction of GLV 147(location 102) 3.3 1.440 140 2.2 0.486 141 3.3 0.736 l 142 2.8 0.497 143 1.7 0.493 Average of 151&l52 2.2 0.021 Average of 151&l52 2.2 0.021 Average of 151&l52 2.2 0.021 Average of 151&l52 2.2 0.021 Average of 151&l52 2.2 0.021 Weichted Mean: 0.38 Sub-Surface Sample Concentrations SML# Exposure Rate (uR/hr) Sum of Fractpn of GLV 148 (location 102) not required 0.112 t O The investigation survey effectively bounded an area of approximately 100 square meters superimposed around SML 102, and the measurement and sample results effectively demonstrated that only one location exceeded the concentration SGLV.

  • The resulting weighted mean " sum of fractions" including the elevated area at SML 102 was less than one (0.38). The results of sediment soil samples collected within this investigation area meet the criteria for release for unrestricted use. i l

f] Fort St. Vrain Nuclear Generating Station Decommissioning Project v Release Record - Survey Area Survey Area / Package ID: E0003 Survey Area / Package

Description:

Farm Pond and Farm Pond Outfall The Farm Pond and Farm Pond Outfall Area were the last portions of the Effluent Pathway and were located just before the St. Vrain River. The Liquid Effluent Pathway (LEP) from the discharge point, was composed of the Goose Quill Ditch, the Jay Thomas Ditch, the Farm Pond and the South Platte River. The Farm Pond was located outside of the restricted area at the north end of the dirt road leading to the farm house The Farm Pond covered approximately 25 acres and was 2-4 feet in depth. The outfall of the pond was a stream bed on the north end of the Farm Pond and extends to the South Platte River. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0003 included the following: Equipment / Components Systems

 ,q V                          None                                            None The unpaved surfaces of this area were surveyed as an Affected Survey Unit. The Affected Survey Unit was not gridded. Measurement locations were marked on survey maps and were not required to be marked in the field due to the possibility of drastic fluctuations in the water level of the pond.

The Survey Package was comprised of two distinct Survey Units. The Survey Units were identified as follows: Location Code Classification / Surface Category Survey Medium Description E0003LZ00lG3 Affected Open Land Area Sediment E000311Z00lG3 Affected Open Land Area Water Survey Area Operational IIistory: The Farm Pond and Farm Pond Outfall Area were in operation prior to August 18,1989 as part of the Liquid Effluent Pathway. The Liquid Effluent Pathway was used to transfer liquid 1 discharges from the Fort St. Vrain Site to the St. Vrain River. The last liquid discharge via the liquid effluent pathway was completed on 7/3/96. v) t Page 2

Survey Area Decommissioning and Remediation Activities: Apart from extensive characterization surveys, no decommissioning or remediation activities O were performed in this area. Previous surveys conducted along the Liquid Effluent Pathway included the following:

  • The Radiological Environmental Program implemented by Colorado State University for Public Service Company of Colorado.
  • Investigations performed by SEG between September 1993 and November 1994.
  • A Scoping Survey performed by SEG between November 1994 and January 1995.
  • A Follow-up Survey performed by SEG during May and June 1996.

Sediment samples collected in this Survey Area during the January 1995 Effluent Pathway Characterization surveys indicated cobalt-60 (Co-60), and cesium-137 (Cs-137). Non-gamma analyses indicated activity of 4.35 pCi/g iron-55 (Fe-55). Effluent Pathway Characterization Survey Results Isotope Minimum Activity (pCi/g) Maximum Activity (pCi/g) Co-60 ( 0-6", sediment) 0.06 - 0.26 Cs-137 (0-6", sediment) 0.22 0.97 Co-60 (6-9", sediment) MDA* MDA* Cs-137 (6-9", sediment) 0.08 0.85

  • Minimum Detectable Activity Samples collected in this Survey Area during the subsequent 1996 Effluent Pathway Follow-up survey performed prior to the Final Survey indicated the following activity levels.

Effluent Pathway Follow-up Survey Results Isotope Minimum Activity (pCi/g) Maximum Activity (pCi/g) Co-60 (0-6", sediment) MDA 0.24 Cs-134 (0-6" sediment) 0.33 0.97 Isolation and Control Measures: level 1 Controls Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned personnel regarding final survey isolation and control measures. No use, storage or movement of radioactive material was permitted in this Survey Area after initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). Containers of radioactive material moved to this area was not permitted to have removable surface activity greater than 250 dpm/100 cm2 Page 3

Isolation and Control Measures: (continued)

   ' The configuration of the Farm Pond and Outfall Area during final survey activities was as follows:
1. The configuration of this Survey Area remained basically the same as the configuration during operations. ,

The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required notification of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo. Survey Area

Conclusions:

The results of sediment and water samples collected within this Survey Area meet the criteria for release for unrestricted use. Survey Area

Description:

Jay Thomas Ditch The Liquid Effiuent Pathway (LEP) from the discharge point, was composed of the Goose Quill Ditch, t'ne Jay Thomas Ditch, the Farm Pond and the South Platte River. The Jay Thomas Ditch was a stream bed beginning upstream of the intersection with the Goose Quill Ditch and terminating at the Farm Pond. The Jay Thomas Ditch was unlined and was 3-6 feet wide, 2-3 feet deep and approximately 2300 feet long. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0004 included the following: Equipment / Components Systems None None (G v f The unpaved surfaces of this area were surveyed as an Affected Survey Unit. The Affected Survey Unit was not gridded. Measurement locations were marked on survey maps and/or survey instructions to designate where measurements were collected. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classification / Surface Category Survey Medium Description E0004LZ00lG1 Affected Open Land Area Sediment Survey Area Operational IIistory: The Jay Thomas Ditch, was in operation prior to August 18,1989 as part of the Liquid Effluent Pathway. The Liquid Effluent Pathway was used to transfer liquid discharges from the Fort St. Vrain Site to the St. Vrain River. The last liquid discharge via the liquid effluent pathway was completed on 7/3/96. p Page 2

l Survey Area Decommissioning and Remediation Activities: Apart from extensive characterization surveys, no decommissioning or remediation activities O were performed in this area. Previous surveys conducted along the Liquid Ef0uent Pathway included the following:

  • The Radiological Environmental Program implemented by Colorado State University for Public Service Company of Colorado.
  • Investigations performed by SEG between September 1993 and November 1994.
  • A Scoping Survey performed by SEG between November 1994 and January 1995.
  • A Follow-up Survey performed by SEG during May and June 1996.

Soil and vegetation samples collected in this Survey Area during the January 1995 EfCuent Pathway Characterization surveys indicated cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137), and europium-152 (Eu-152). Non-gamma analyses indicated activity of 10.7 to 24.7 pCi/g iron-55 (Fe-55) and 0.13 pCi/g strontium-90 (Sr-90). Effluent Pathway Characterization Survey Results Isotope Minimum Activity (pCi/g) Maximum Activity (pCi/g) 1 Co-60 (sediment) MDA* 3.85 Cs-134 (sediment) MDA* 1.09 Cs-137 (sediment) MDA* 3.87 Eu-152 (sediment) MDA* 0.36 Co-60 (vegetation) 2.64 33.64 Cs-134 (vegetation) MDA* 0.28 Cs-137 (vegetation) 0.49 6.62

  • Minimum Detectable Activity Samples collected in this Survey Area during the subsequent 1996 Effluent Pathway Follow-up survey performed prior to the Final Survey indicated the following reduction in the activity levels.

Isolation and Control Measures: Level 1 Controls O

  '(d Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned personnel regarding fm' al survey isolation and control measures.

No use, storcge or movement of radioactive material was permitted in this Survey Area after initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). Radioactive material moved to this area was not permitted to have removable surface activity greater than 250 dpm/100 cm 2, The configuration of the Jay Thomas Ditch during final survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required notification of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo.

(7 Fort St. Vrain Nuclear Generating Station Decommissioning Project Release Recortl- Stuvey Area Survey Area / Package ID: E0005 i Survey Arra/ Package Descripdon: East & West Settling Basins and East & West l Storage Basins The East & West Settling Basins and East & West Storage Basins were located on the north side of the Restricted Area. The basins were a part of System 41, Circulating Water System. The basins, which were constructed of concrete, were used to collect, settle and store make-up water from the Platte and/or St. Vrain Rivers. At the time of Final Surveys in this area, the West Settling Basin was partially dry while the East Settling Basin was full of water. The Storage Basins also had concrete sides, but were constructed with soil bottoms. At the time of Final Surveys in this area, the West Storage Basin was dry while the East Storage Basin was full of water. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0005 included the following: O V Equipment / Components Systerns None None The paved and unpaved surfaces of this area were surveyed as an Unaffected Survey Unit. The Unaffected Survey Unit was not gridded. Measurement locations were marked on survey maps and were not required to be marked in the field due to the possibility of drastic fluctuations in the water level of the basins and ponds. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classificadon/Su:rface Category Survey Medium Description E0005LZ001FZ Unaffected Open Land Area Sediment Survey Area Operational History: The East & West Settling Basins and East & West Storage Basins were in operation prior to August 18, 1989 as part of System 41, Circulating Water System. The Circulating Water System provided coolant to the Inain condensers and served as a water reservoir for the Fire o Protection System, and in an emergency, as the back-up to the Service Water System. This V portion of System 41 was Unaffected and was surveyed as an Open Land Area versus a Plant System. Page 2

Survey Area Decommissioning and Remediation Activities: No decommissioning or remediation activities were performed in this area. No radiological O survey results were available for review at the commencement of Final Surveys in this Survey Area, nor was there any indication that radiological samples were ever taken in the basins. Isolation and Contml Measures: Level 2 Controls Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned personnel regarding final survey isolation and control measures. No use, storage or movement of radioactive material was permitted in this Survey Area after initiation of fmal survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). Radioactive material moved to 2 this area was not permitted to have removable surface activity greater than 250 dpm/100 cm , The configuration of the East & West Settling Basins and East & West Storage Basins during fmal survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations,
2. All access points to this area were posted with Level 2 Isolation Labels.

The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required notification or the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo. Survey Aira

Conclusions:

The results of sediment samples collected within this Survey Area meet the criteria for release for unrestricted use. Results of QC samples obtained within this Survey Area verify that Initial measurement results meet the criteria for release for unrestricted use. SuiTey Area

( Fort St. Vrain Nuclear Generating Station Decommissioning Project Release Record - Survey Area Survey Area / Package ID: E0006 Survey Area / Package

Description:

Jay Thomas Ditch Banks The Jay Thomas Ditch Banks were the upper portions of the Jay Thomas Ditch, which was a major part of the Liquid Effluent Pathway. The Liquid Effluent Pathway (LEP) from the discharge point, was composed of the Goose Quill Ditch, the Jay Thomas Ditch, the Farm Pond and the South Platte River. The Jay Thomas Ditch was a stream bed beginning upstream of the intersection with the Goose Quill Ditch and terminating at the Farm Pond. The Jay Thomas Ditch was unlined and was 3-6 feet wide,2-3 feet deep and approximately 2300 feet long. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0006 included the following: Equipment / Components Systems None None x.j The unpaved surfaces of this area were surveyed as an Affected Survey Unit. The Affected Survey Unit was not gridded. Measurement locations were marked on survey maps and/or survey instructions to designate where measurements were collected. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classification / Surface Category Survey Medium Description E0006LZ00lG1 Affected Open Land Area _ Sediment Survey Area Operational IIIstory: The Jay Thomas Ditch Banks, was in operation prior to August 18,1989 as part of the Liquid Effluent Pathway. The Liquid Effluent Pathway was used to transfer liquid discharges from the Fort St. Vrain Site to the St. Vrain River. The last liquid discharge via the liquid effluent pathway was completed on 7/3/96. m v i Page 2 ; I

Survey Area Decommissioning and Remediation Activities: Apart from extensive characterization surveys, no decommissioning or remediation activities O were pe-formed in this area. Previous surveys conducted along the Liquid Effluent Pathway included the following:

  • The Radiological Environmental Program implemented by Colorado State University for Public Service Company of Colorado.
  • Investigations performed by SEG between September 1993 and November 1994.
  • A Scoping Survey performed by SEG between November 1994 and January 1995.
  • A Follow-up Survey performed by SEG during May and June 1996.

Soil and vegetation samples collected in this Survey Area during the January 1995 Effluent Pathway Characterization surveys indicated cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137), and europium-152 (Eu-152). Non-gamma analyses indicated activity of 10.7 to 24.7 pCi/g iron-55 (Fe-55) and 0.13 pCi/g strontium-90 (Sr-90). Effluent Pathway Characterization Survey Results Isotope Minimum Activity (pCi/g) Maximum Activity (pCi/g) Co-60 (sediment) MDA* 3.85 Cs-134 (sediment) MDA* 1.09 Cs-137 (sediment) MDA* 3.87 Co-60 (vegetation) 2.64 33.64 Cs-134 (vegetation) MDA* 0.28 Cs-137 (vegetation) 0.49 6.62

  • Minimum Detectable Activity Samples collected in this Survey Area during the subsequent 1996 Effluent Pathway Follow-up survey performed prior to the Final Survey indicated the following reduction in the activity levels.

Effluent Pathway Follow-up Survey Results Isotope Minimum Activity (pCi/g) Maximum Activity (pCi/g) Co-60 (sediment) 0.154 3.750 Cs-134 (sediment) MDA MDA Cs-137 (sediment) 0.050 3.110 0 Page 3

Isolation and Control Measures: level 1 Controls V Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned j persennel regarding fmal survey isolation and control measures. No use, storage or movement of radioactive material was permitted in this Survey Area after  ; initiation of fmal survey measurements without authorization from the Technical Project  ! Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). Radioactive material moved to this area was not permitted to have removable surface activity greater than 250 dpm/100 cm 2 The configuration of the Jay Thomas Ditch Banks during final survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations The above described configuration was the final configuration at completion of final survey measurements. Configuration changes, subsequent to completion of final surveys, required notification of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo.

Survey Area

Conclusions:

The results of sediment samples collected within this Survey Area meet the criteria for release O Lj for unrestricted use. Survey Area

r3 Fort St. Vrain Nuclear Generating Station Decommissioning Project t U Release Record - StuTey Ama Survey Area / Package ID: E0007 Survey Aira/ Package

Description:

Sewage Lagoon 1 and 2 and East and West Evaporation Ponds The Sewage Lagoon 1 and 2 and East and West Evaporation Ponds were located on the north side of the Protected Area fence. The lagoons were a part of System 44, Domestic Water System. Both the Settling Basins and the Evaporation Ponds were lined with a heavy poly vinyl material layered over soil. At the time of Final Surveys, the lagoons were half-full of water while both the east and west ponds were dry. The west pond contained a layer of dry, white residue. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0007 included the following: Equignent/ Components Systems /^ None None The unpaved surfaces of this area were surveyed as an Unaffected Survey Unit. The Unaffected Survey Unit was not gridded. Measurement locations were marked on survey maps and were not required to be marked in the field due to the possibility of drastic fluctuations in the water level of the ponds and basins. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: location Code Classification / Surface Category Survey Medium Description E0007LZ00lFZ Unaffected Open Land Area Sediment Sun'cy Area Operational IIistory: The Sewage Lagoon 1 and 2 were part of System 44, Domestic Water while the West and East Evapciation Ponds were part of System 33, Water Treatment System. The sewer lagoons provided a final collection, settling and evaporation area for liquid sewer effluent from site buildings. The Water Treatment System served to remove, by ion exchange and filtration, suspended and dissolved solids from the condensate, preventing subsequent deposition in the 7 steam generators. The evaporative ponds were used as a collection and evaporation area for the

  ) waste water from system 33.

These portions of Systems 33 and 44 were classified as Unaffected and were surveyed as open land areas versus plant systems. Page 2

Survey Area Decommissioning and Remediation Activities: No decommissioning or remediation activities were performed in this area. No radiological O survey results were available for review at the commencement of Final Surveys in this Survey Area, nor was there any indication that radiological samples were ever taken in the basins. Isolation and Contml Meastnes: Level 2 Controls Prior to the final survey of Group E Survey Areas, training sessions were held with site assigned personnel regarding final survey isolation and control measures. No use, storage or movement of radioactive material was permitted in this Survey Area after initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey Lead Engineer (FSLE). The configuration of the Sewage Lagoon 1 and 2 and East and West Evaporation Ponds during final survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations,
2. Gates to the Restricted Area were posted with Level 2 Isolation Labels.

The above described configuration was the final configuration at completion of final survey measurements. Configuration changes. subsequent to completion of final surveys, required notification of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo. Survey Area

Conclusions:

The results of gamma isotopic analysis of the sediment samples within this Survey Area indicates the Survey Area meets the criteria for release for unrestricted use. QC sample measurement results within this Survey Unit do not exceed the Administrative Action Levels or SGLVs for Unaffected Open Land Areas. These results confirm the conclusions regarding suitability of the Survey Unit for release for unrestricted use. Survey Arra

Description:

Irrigation Ditch 2, North and South Marsh The Irrigation Ditch 2, North and South Marsh were used to distribute water from the Effluent Pathway to adjacent pastures and farm land. Irrigation Ditch 2 was located on the west side of the Goose Quill Ditch and north of the Farmhouse Road. The North Marsh was west of the irrigation Ditch 2 and north of the Farmhouse Road. The North Marsh was within the Permanent Pasture surveyed as Survey Package ID: E0011. The South Marsh was northeast of thejunction of Goose Quill Ditch and County Road 19%, bordered on the south and east side by Goose Quill Ditch and upstream ofIrrigation Ditch 2. The South Marsh was within the Permanent Pasture surveyed as Survey Package ID: E0012. Major equipment and components included in this Survey Area and systems residing within or traversing Survey Package ID: E0008 included the following: (] LJ Equipment / Components Systems None None The unpaved surfaces of this area were surveyed as an Affected Survey Unit. The Affected Survey Unit was not gridded. Measurement locations were marked on survey maps and/or survey instmetions to designate where measurements were collected. The Survey Package was comprised of one distinct Survey Unit. This Survey Unit was identified as follows: Location Code Classification / Surface Category Suney Medimn Description E0008LZ00lG1 Affected Open Land Area Surface Soil Survey Area Operational IIistory: The Irrigation Ditch 2, North and South Marsh were in operation prior to August 18,1989 as part of the Liquid Effluent Pathway. The Liquid Effluent Pathway was used to transfer radioactive discharge liquids from the Fort St. Vrain Site to the St. Vrain River while the ditches, including Irrigation Ditch 2, served to distribute water from the Effluent Pathway to { adjacent pastures and farm land. The North and South Marshes become flooded during breaks in the Goose Quill Ditch. Liquid releases were listed in the Public Service Company's Annual (,o) Effluent Release Reports. Page 2 l

Survey Area Operational IIistory: (continued) Previous investigations conducted along the Liquid Effluent Pathway included the following: O The Radiological Environmental Program implemented by Colorado State University for Public Service Coripany of Colorado. Investigations performed by SEG between September 1993 and November 1994. A Scoping Survey performed by SEG between November 1994 and January 1995. A Follow-up Characterization Survey performed by SEG June 1996. Radioactive contamination was identified in this area during the EfDuent Pathway Characterization Survey. Survey Area Decommissioning and Remediation Activities: No decommissioning or remediation activities were performed in this area. Fifteen soil samples collected in this Survey Area during the Effluent Pathway Characterization indicated the following activity levels for the radioactive isotopes cobalt-60 (Co-60), cesium-134 (Cs-134) and cesium-137 (Cs-137). Effluent Pathway Characterization Survey Results Isotope Minimmn Activity (pCi/g) Maximum Activity (pCi/g) l Co-60 (soil) MDA* 22.62 Cs-134 (soil) MDA* 1.06 Cs-137 (soil) 0.13 17.90

Isolation and Contml Measums: 12 vel 2 Controls o k Prior to the fmal survey of Group E Survey Areas, training sessions were held with site assigned personnel regarding final survey isolation and control measures. No use, storage or movement of radioactive material was permitted in this Survey Area after initiation of final survey measurements without authorization from the Technical Project Supervisor (TPS) and the Final Survey lead Engineer (FSLE). Radioactive material moved to this area was not permitted to have removable surface activity greater than 250 dpm/100 cm 2. The con 5guration of the Irrigation Ditch 2, North and South Marsh during final survey activities was as follows:

1. The configuration of this Survey Area remained basically the same as the configuration during operations.

The above described conGguration was the final conHguration at completion of fmal survey measurements. Con 0guration changes, subsequent to completion of final surveys, required noti 6 cation of the Technical Project Supervisor (TPS) and the Final Survey Operations Supervisor (FSOS) and the approval of PSCo. Survey Ana

Conclusions:

The results of sediment soil samples and exposure rate measurements collected within this

 ]U  Survey Area meet the criteria for release for unrestricted use.

Results of QC measurements obtained within this Survey Area verify that Initial measurement results meet the criteria for release for unrestricted use.

Survey Unit Investigations: Investigation No.1 09/24/ % The initial survey package required modification to comply with the requirements specified in  : TBD-209, Table 7.4. Specifically, SMLs 48-50 collected in the North Marsh under survey I package E0012, and SMLs 1,2,11-18, 20 and 21 collected in the South Marsh under survey package E00ll needed to be moved to this survey package. Both the North Marsh and South Marsh SML needed to be changed. The soil samples obtained in Ditch #1 and Ditch #3 needed to be moved to survey package E0010, re-coded and renumbered. Following addition of the two marshes and removal of the two ditches,10 biased and 6 unbiased samples needed to be obtained. Additionally, a 100% gamma scan is required and exposure rate measurements needed to be obtained and two QC samples needed to be collected to meet the minimum required samples for the survey unit. The initial soil sample data was collected in Ditch 2 using a survey unit classification code of ,

  "GZ" which needed to be updated to "Gl". The initial samples collected in Ditches #1 and #3           l using a survey unit classification code of "GZ" needed to be updated to "G3", and changed from         i E0008 to E0010.

l The survey area descriptions and the Survey Area Breakdown needed be revised to reflect the modifications. O Several actions were required to make the above changes, the following data base corrections were made:

a. Samples collected under the initial package design in Ditch #1 using E0008LZ00lGZT01 at SML #s 1-17 were re-coded as E0010LZ001G3T01 and renumbered 51-67, respectively.
b. Samples collected under the initial package design in Ditch #3 using E0008LZ00lGZT01 at SML #s 37-50 were re-coded as E0010LZ00lG3T01 and renumbered 68-81, respectively.
c. Samples collected under the initial package design in Ditch #2 using E0008LZ00lGZT01 at SML #s 18-36 were re-coded as E0008LZ00lGIT01 and renumbered 1-19, respectively.
d. QC samples collected under the initial package design in using E0008LZ00lGZQ01 at SML #s 5 and 45 were re-coded as E0010LZ00lG3Q01 and renumbered 55 and 76, respectively.
e. QC sample collected under the initial package design in using E0008LZ00lGZQ01 at SML # 1 25 was re-coded as E0008LZ00lG3Q01 and renumbered as SML 8. l Additionally, the South Marsh from initial package E00ll and the North Marsh form E0012 were added to this package.

l

a. Samples collected under the initial package design using E0011LZ00lGZT01 at SML #s 1, 2,11-18, and 20-21 were re-coded as E0008LZ00lGIT01, and renumbered 20-31, respectively,
b. Samples collected under the initial package design number E0012LZ00lGZT01 at SML#s '

48-50 were coded E0008LZ00lGIT01 and renumbered 32-34, respectively. I Page 8

Survey Unit Investigations: (continued) The initial radiochemistry results were superseded and the new results were placed in the O package. All applicable forms were re-signed and annotated with the Change number. The Survey Area Breakdown was modified to reflect the new survey area description. Additionally, an addendum sub-package was prepared to collect ten biased and 6 unbiased samples, two QC measurements and a 100% gamma scan of the areas. No additional actions were required to close this investigation. Investigation No.2 10/12/96 The concentration of licensed activity in one soil sample obtained in Ditch 2 was in excess of the concentration SGLV. The elevated sample was obtained at SML 47. As a result of the gamma scan of ditch 2 (as required by Addendum sub-package, T02, Investigation #1) additional samples were collected at areas of suspected elevated exposure rate. These locations were assigned SMLs 52,53,48, and 54, and these sample locations effectively bound SML #47 to the north. Ilowever, only one SML was previously collected in the southern direction. Additional samples needed to be collected to adequately bound SML #47 to the south. Additionally, gamma scans and soil samples were to be obtained from the adjacent banks to verify that the area of elevated activity had been adequately characterized. SML# Fraction of Concentration SGLV Elevated Imcation: 47 1.10 To the Nor h: 54 48 0.507 0.664 h 53 0.598 52 0.453 To the South: 46 0.292 A sub-package was prepared to perform an investigation survey and a 100% gamma scan of the banks adjacent to SML 47 was performed. The gamma scan survey extended out east and west approximately 3 meters and overlapped approximately 5 meters south of SML 47 to 5 meters north. No additional areas of elevated exposure rate were identified during the gamma scan survey. Four surface soil samples were collected from within the ditch south of SML 47, and four surface soil samples were collected from the ditch banks bounding SML 47, (two on the west and two on the east side) for a total of 8 surface soil samples. SML numbers 59-63 were used for the samples within the ditch, and SML numbers 63-66 were used for the samples from the banks. An exposure rate measurement utilizing the MicroSpec-2 was collected at each surface soil sample location at I meter from the surface. A sub-surface soil sample at the same location as SML 47 was collected using SML number 58 and with survey reason code G01 - Investigation" The survey reason code was "G01 - Investigation". 9 Page 9

Survey Unit Investigations: (continued)  ! 'O The results of the initial soil samples and exposure rate measurements for the investigation survey were as follows: i Sample Concentrations for Weinhted Calculation of the Mean

The area of the investigation area was not a standard 10 meter by 10 meter area since the ditch is irregularly shaped, and SML 47 was obtained from the bottom of the ditch. The length of the investigation area was approximately 33 meters along the ditch,9 meters upstream of SML 47 and 24 meters downstream of SML 47. The width of the investigation area varied from 3 meters to 9 meters with the widest dimension at SML 47. To arrive at a conservative estimate of the weighted mean for residual concentrations, all samples used in the calculation were obtained from the bottom of the ditch, rather than locations designated by superimposing a 10 meter by 10 meter grid across the ditch at SML 47. These locations were most likely to contain residual activity, since the activity is known to have originated from the interior of the ditch. Page 10 l

Survey Unit Investigations: (continued) The 4 samples collected from the banks confinned our understanding that the majority of the O residual activity is confined to the interior of the ditch, and the residual activity in the pasture land adjacent to the ditch had been adequately characterized. The resulting weighted mean " sum of fractions" including the elevated area at SML 47 is less than one (0.54). The results of sediment soil samples collected within this Survey Area meet the criteria for release for unrestricted use and no further action was required. O O i Page 11
