Executive Summary The data from the San Onofre Nuclear Generating Station (SONGS) Radiological Environmental Monitoring Program (REMP) clearly indicates that SONGS had no measurable radiological environmental impact during 1999.
Preparation of the 1999 Annual Radiological Environmental Operating Report (AREOR) used the data reduction protocol described in NUIREG/CR-4007. A meaningful analysis of data at, near, or below the detection limit must necessarily involve a consideration of the degrees of uncertainty associated with the data. Excluding naturally occurring radionuclides, approximately 5% of the 1999 SONGS REMP data set was above the critical level (1.64 sigma),
which is characteristic of a database consisting entirely of values statistically equal to zero. The data above the critical level have been summarized in table B-3 of Appendix B. The plant related radionuclides (Cs-137 in soil and 1-131 in kelp) detected at the 3 sigma (99%) confidence level may be attributable to fallout from nuclear weapons testing (Cs-137) and medical administrations of radionuclides (1-131). These isotopes have been detected at indicator as well as control locations in past years. The naturally occurring radionuclides (Be-7, K-40, and Th 228) detected at the 99% detection confidence level were observed in both control and indicator locations at substantially similar concentrations and are not related to the operation of SONGS.
The balance of 1999 SONGS REMP database displays behavior statistically equal to a null set.
Refer to Appendix B for a more detailed discussion.
INTRODUCTION SONGS consists of three pressurized water nuclear reactors housed in separate containment buildings. Unit 1 attained initial criticality June 1967 and was permanently retired from service in November 1992. Unit 2 and Unit 3 attained initial criticality in July 1982 and August 1983, respectively, and have been in operation to date.
The purpose of the REMP is to quantify ambient radiation levels in the environs of SONGS, and to identify and quantify concentrations of radioactivity in various environmental media in the vicinity of SONGS which have a potential radiation exposure pathway to man.
Thermoluminescent dosimeters (TLDs) were used to measure direct radiation levels. Sampled environmental media include soil, shoreline sediment (beach sand), air (particulate & iodine),
local crops, non-migratory marine species, kelp, drinking water, ocean water, and ocean bottom sediments. Each of the samples was analyzed for both naturally-occurring and SONGS-related radionuclides.
The REMP is conducted in accordance with Section 5.0 of the SONGS Unit 1 and 2/3 Offsite Dose Calculation Manuals (ODCM).
To conform with 10CFR Part 50, Appendix I, Section IV-B.2, measured radioactivity concentrations in the environmental samples have been compared against predicted (calculated) ones to evaluate the relationship between quantities of radioactive material released in effluents and resultant radiation doses to individuals from principal pathways of exposure.
I
This comparison was documented in Appendix D of the 1993 AREOR, issued April, 1994.
During 1999 no plant related radionuclides attributable to the operation of SONGS were detected.
A land use census was performed in 1999 to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the monitoring program are made if required by the results of this census. Appendix F of the report identifies changes to the census and the resultant dose increase, if any, to individuals from principal pathways of exposures in conformance with 10CFR Part 50, Appendix I, Section IV. B.3.
OBJECTIVES
- 1.
To fulfill the radiological environmental monitoring requirements of the ODCM and the Technical Specifications.
- 2.
To detect any significant increase in the concentration of radionuclides in critical pathways.
- 3.
To detect any significant change in ambient gamma radiation levels.
- 4.
To verify that the operation of SONGS Units 1, 2 and 3 have no assessable detrimental effects on the health and safety of the public or the environment.
SAMPLE COLLECTION Samples of various environmental media were obtained in order to meet the stated objectives.
The selection of sample types was based on established critical pathways for the transfer of radionuclides through the environment to individuals, and the evaluation of data during the operational phase. Sampling locations were determined with consideration given to site meteorology, local demography, and land uses. Refer to Appendix A for a complete list of REMP sample locations as described in Table 5-4 and Table 5-5 of the ODCM.
Sampling locations were divided into two classes, indicator and control. Control stations were at locations considered to be unaffected by SONGS operations. All others are considered indicator locations and may be potentially effected by SONGS operations.
SOURCES OF RADIOACTIVITY Plant-specific radionuclides are produced in the normal operation of a nuclear power plant.
Most of the fission products are retained within the fuel and its cladding. A small fraction of fission products such as cesium-137 (Cs-137) and iodine-131 (1-131), and activation products such as cobalt-60 (Co-60), are present in the primary reactor cooling system. Noble gases are also produced during the fission process.
2
Radioactive liquid and gaseous waste releases to the ocean and the atmosphere may contain very minute concentrations of plant-produced radionuclides. The airborne radioactive noble gases released are mostly xenon and krypton, which are inert (non-reactive). They do not concentrate in the body, but they may contribute to human radiation exposure as an immersion source for whole body exposure. Xenon-133 and xenon-135 are the major radioactive noble gases released to the atmosphere, and their calculated offsite beta and gamma air doses are less than 0.1 mrad per year.
The releases of iodines and particulates in the gaseous and liquid effluents are small. The major radionuclides of interest are 1-131, Cs-134, Cs-137, Co-58, and Co-60. The total releases for these radionuclides were well below applicable regulatory limits.
Tritium (H-3), the radioactive isotope of hydrogen, is the predominant radionuclide in the liquid effluents and is also present in gaseous effluents. Tritium is produced in the reactor water (coolant) as a result of Boron activation and other nuclear reactions.
EXPOSURE PATHWAY Figure 1 illustrates various exposure pathways resulting in radiation dose to the surrounding population from operation of a nuclear facility. Only a few pathways will have real dose potential and require detailed calculations.
- a.
External Exposure External exposure to people during normal operations will include radioactive gases in gaseous effluent plumes, radionuclides deposited on soil, and vegetation, or shoreline sediments. Direct exposure from radionuclides in water during recreation or commercial fishing activity is insignificant. Accumulation in sediments has the greater potential as a source of exposure. Gamma dosimeters (TLDs) are the usual means of measuring direct radiation exposure since significant dose contributors are gamma-emitters.
- b.
Internal Exposure The release of radioactivity in liquid effluents involves pathways such as fish consumption and direct exposure from the ocean water by swimming and the shoreline activities. Consumption of fish or crops from the area receiving liquid effluents and breathing contaminated air from the gaseous effluents releases are the most probable sources of internal exposure.
The doses calculated from gaseous effluent, tritium, radioiodines, and particulates of the gaseous effluent within a five-mile distance from the plant were summarized in Appendix D of the 1993 AREOR. Refer to the 1993 AREOR for detailed information on this analysis.

REGULATORY LIMITS, GUIDANCE, AND REQUIREMENTS 10CFR50 The Code of Federal Regulations Title 10, Part 50, Appendix I.
40CFR190 The EPA has established environmental radiation protection standards for nuclear power plants in 40CFR190. The standards for normal operation recommended that the dose from all discharges of radioactivity should not exceed 25 mrem/yr. These limits are applicable to the sum of both liquid and gaseous effluents and direct radiation. The environmental doses calculated at SONGS are a small fraction of the dose limits established by the Environmental Protection Agency (EPA).

Effluent Streams and the Environment, 1979 NUREG/CR-4007 Lower Limit of Detection: Definition and Elaboration of a Proposed Position for Radiological Effluent and Environmental Measurements, 1984 DATA MANAGEMENT The tabulated means, ranges and standard deviations presented in Appendix B were calculated following the standard format specified in Regulatory Guide 4.8, the Radiological Assessment Branch Technical Position, revision 1, 1979, and in accordance with the protocol outlined in NUREG/CR-4007. The REMP software package was used to perform the statistical analysis and tabulation of the data.
The REMP data are reviewed for accuracy and comparison against NRC reporting levels, and then entered into the REMP database. One of the REMP menus flags measurements exceeding the administrative levels (10% of the NRC reporting levels) established by Southern California Edison (SCE). The aposteriori minimum detectable concentration (MDC) is compared to the maximum value for the a priori Lower Limit of Detection (LLD) specified in the ODCM. This insures that regulatory limits for the maximum LLD are met.
The impact of SONGS on the surrounding environment was assessed through a series of analyses. These analyses included: data reduction, comparisons of indicator to control locations, and summary (Appendix B); comparison of operational to preoperational environmental data (Appendix D); summary of deviations from sampling requirements and corrective actions taken (Appendix E); and finally the results of the 1999 Land Use Census reports including changes in the Land Uses from the previous year (Appendix F).
All Radiological Environmental Monitoring activities for San Onofre are assessed by Quality Assurance requirements as defined in Regulatory Guide 4.15. The Contracted Environmental Analysis Laboratory (CEAL) participated in the EPA interlaboratory comparison program as part of quality assurance requirements for environmental monitoring. In anticipation of the discontinuance of the EPA cross check program, the CEAL initiated participation in alternate cross check programs which meet the intent of Reg Guide 4.15. A split sampling program was 5
conducted in cooperation with the State of California Department of Health Services. Refer to Appendix C.
DETECTION LIMIT TERMINOLOGY This report utilizes four distinct terms to describe the concept of "lower limit of detection" at various detection confidence levels. The terms are briefly defined below. For a more thorough discussion the reader should refer to NUREG/CR-4007.
Critical level - Defined as 1.64 sigma. For a sufficiently large database of isotopically analyzed sample results, with the "true" activity being equal to zero, approximately 5% of the results should be above the critical level. The 1999 SONGS REMP data above the critical level have been summarized in table B-3 of Appendix B. Approximately 5% of the total listed analyses are above the critical level.
Lower Limit of Detection (LLD) - The LLD is the a priori (before the fact) lower limit of detection. This value is calculated for each isotope and every matrix based on typical or expected values of decay time, sample size, counter efficiency, etc. These values are listed in the ODCM and represent the maximum permissible value for the "lower limit of detection" for specified sample media.
Minimum Detectable Concentration (MDC) - The MDC is the a posteriori (after the fact) lower limit of detection based on actual decay time, measured sample size, counter efficiency as determined by recent calibration, etc. The MDC is compared to the LLD to verify that the measurement met the ODCM requirements for the maximum value of the LLD for the listed analytes. Values above the MDC are presumed to represent "detected" activity at the 95%
detection confidence level.
Three sigma (99% confidence level) - Sample analysis results above this level are "detected" with less than a 1 % probability of a "false positive."
6
CONCLUSION Levels of radioactivity in environmental media are a function of several factors including: site release rates; meteorology; number, location, size and date of nuclear weapons tests; seasonal variability of fallout; soil conditions; local terrain and variability in the natural environment.
Radiological environmental data collected throughout 1999 have been evaluated to determine the impact, if any, of San Onofre operations on the surrounding environment. To accomplish this, several methods of evaluation were employed, namely:
- 1.
Compilation and verification of all data, as well as a determination of those data considered to be significantly greater than background levels.
- 2.
Environmental dose calculations and correlation of effluent releases with environmental concentrations (Refer to the 1993 AREOR).
- 3.
Examination of time-dependent variations of pertinent radioisotopes in selected environmental media throughout the year at both indicator and control locations.
- 4.
Comparison of radioactivity in various media in 1999 against the levels observed in pre-operational years.
- 5.
Historical trending of radionuclides in various media during operational years.
In comparing these findings to the conservatively-defined limits of the facility operating licenses, it is concluded that the radiological environmental impact of the operation of SONGS through 1999 has been negligible, and the resulting dose to man is negligible.

SUMMARY
, RESULTS, AND DISCUSSIONS OF 1999 ENVIRONMENTAL DATA 22
SUMMARY
To assess the changes or trends in the radioactivity level in the environment over the past year, the data from January 1999 to December 1999 were evaluated. The 1999 REMP data were evaluated according to the criteria described in NUREG/CR-4007 and with the methodology described by Currie (1968).*
The REMP data above the critical level (1.64 times one sigma) was reduced and tabulated in Table B-3 in accordance with the format specified in Reg Guide 4.8. It should be noted that in an ideal database with the "true" value of each data point equal to zero, five (5)% of the values should be expected to be above the critical level.
Excluding natural radionuclides (Be-7, K-40 and Th-228), approximately (5%) of the data listed in Table B-3 is above the critical level. Thus the 1999 SONGS REMP database, when examined in accordance with the Currie data reduction protocol, leads to the conclusion that SONGS had no statistically significant radiological environmental impact. A summary of the type and number of REMP samples obtained in 1999 appears in Table B-2.
As noted above, the SONGS REMP data base behaves substantially similar to a data base with values statistically indistinguishable from zero for station related isotopes. The exceptions, summarized in Table B-i, include nine (9) isotopically analyzed samples with station related activity reported above the a posteriori MDC. All sample values were significantly less than the NRC reporting levels. 1-131 was detected in kelp and Cs-137 was detected in soil. These radionuclides have been detected in CONTROL as well as indicator locations in previous years.
Cs-137 is commonly detected in environmental sediment samples because of fallout from weapons testing. Cs-137 has been intermittently detected in the indicator and in the CONTROL soil samples in past years and no correlation between Cs-137 level and proximity to the plant has been observed. The data strongly suggest that the low level Cs-137 in certain sediment samples is due to fallout and is not due to the operation of SONGS. 1-131 is a medically administered radionuclide which is often detected in sewage plant outfalls, including those routed to the Pacific Ocean. 1-131 has been detected in CONTROL and indicator Kelp samples in past years.
The Kelp CONTROL sample 1-131 level has typically been slightly higher than the indicator sample 1-131 concentration, suggesting that the source of the 1-131 is external to SONGS. We conclude that SONGS had a negligible radiological environmental impact during 1999.
Historical trending of data near and below the detection limits is necessarily limited. The concentration of radionuclides in the environs of SONGS has trended downward since the early to mid 1980s. In the past three years only a few REMP analysis results have been above the detection limit. These isotopes are detected in CONTROL as well as indicator locations and there are known sources for these radionuclides external to SONGS. The overall trend of the REMP data at SONGS is de minimis levels of anthropogenic radioactivity with occasional samples showing radioactivity above the a posteriori MDC. The 1993 AREOR included detailed historical data.

RESULTS AND DISCUSSIONS OF 1999 ENVIRONMENTAL DATA A.
Direct Radiation The purpose of this program element was to measure the quarterly environmental gamma radiation in the vicinity of SONGS. To accomplish this task, calcium sulfate (CaSO 4) thermoluminescent dosimeters (TLDs) were placed at a minimum of 30 indicator and CONTROL locations. They were collected and analyzed quarterly in accordance with ANSI N545 standards. TLDs within five miles of SONGS were considered indicator locations. TLDs located greater than five miles from SONGS were considered CONTROL locations. The indicator locations are selected as inner and outer rings for all three Units as required by Unit 1 and Units 2/3 Offsite Dose Calculation Manuals (ODCMs). Additional TLDs are placed at locations of interest such as schools and hospitals.
Six laboratory CONTROL TLDs were analyzed quarterly. TLD numbers 17, 18, and 60 are used for background dose normalization. TLDs #A and #B are used to compensate for transit dose. A fader TLD is used to compensate for the time and temperature dependent "fade" associated with this type of dosimeter.
After the samples were analyzed, the measured doses were corrected for pre and post field exposure times. The average indicator location dose was 15.5 mR with a range of 9.0 to 27.6 mR. The average CONTROL location dose was 14.8 mR with a range of 11.9 to 19.5 mR. The 1999 REMP TLD data has been grouped into four categories based on distance from SONGS for the purposes of trending any correlation between distance from SONGS and total annual dose.
1999 REMP TLD data (Average Dose vs. Distance from SONGS)
Average Quarterly Dose in m.R TLDs < 0.5 miles from SONGS 15.9 TLDs > 0.5 miles AND < 1.0 mile from SONGS 14.4 TLDs > 1.0 mile AND < 5.0 miles from SONGS 15.8 TLDs > 5 miles from SONGS (CONTROL TLDs) 14.8 These data indicate no correlation between total dose and distance from SONGS. The variations in the average dose is approximately equal to the median one sigma variation of measurement (1.00 mR per quarter). Statistically, the CONTROL and indicator doses are equal. The indicator location at the Southeast Site Boundary (location # 13, at 0.4 miles ESE of Units 2/3 midpoint) had the highest TLD average in 1999. The operation of SONGS had no measurable impact on this sample medium.
Figures 2A & 2B compare environmental radiation levels of indicator and CONTROL locations for the operational year 1999 and for previous years. These figures show the close correlation between the CONTROL and indicator location TLD dose data.
24
Nonroutine Direct Radiation Samples During 1999, eight additional TLD sample locations were installed to ensure verbatim compliance with the SONGS emergency plan. These TLDs were not required by the ODCM, but the sample results are included in Table B-3.
B.
Airborne Particulate, Iodine, and Composite Isotopic Analyses Air particulate samples were collected on a weekly basis from eight indicator locations and from one CONTROL location. The samples were analyzed for gross beta activity, 1-131, and composited quarterly for gamma isotopic analysis. Sample locations were selected according to the requirements of the Unit 1 and Units 2/3 Offsite Dose Calculation Manuals.
Gross beta analysis is a measure of total radioactivity of beta-emitting radionuclides in a sample.
Beta radiation is emitted by many radionuclides, but beta decay gives a continuous energy spectrum rather than the discrete lines or peaks associated with gamma radiation. Gross beta measurements only indicate whether the sample contains normal or abnormal concentrations of beta-emitting radionuclides and does not identify specific radionuclides. Gross beta measurement data serves as a screening tool to determine if further analysis is required.
Nearly all gross beta activity analysis results were above the 3 sigma confidence level (99%
probability of activity being present). The concentration of gross beta activity in the samples collected from the indicator locations ranged from 0.0073 to 0.075 pCi/m3, averaging 0.0239 pCi/m3 of air. The concentrations of gross beta activity in the samples from the CONTROL location ranged from 0.0103 to 0.066 pCi/m3, averaging 0.0238 pCi/m3 of air. The CONTROL and indicator locations gross beta data show a close correlation. Figure 3C shows the variation in gross beta activity level in 1999 at different locations. These graphs show a close correlation between the indicator and CONTROL location data.
Per the requirements of Unit 1 and Units 2/3 ODCM, Section 5, Table 5.1, an assessment was performed to determine whether the gross beta activity of the indicators exceeded 10 times the background (CONTROL location #15).
The results showed that indicator locations maximum gross beta activity in air in 1999 was 0.075 pCi/m3 and the CONTROL location average was 0.0238 pCi/m3. No action was taken since the indicator location value did not exceed ten times the annual average gross beta activity of the CONTROL.
All samples analyzed for 1-131 were less than the 3 sigma confidence level and all 1-131 samples were less that the a priori lower limit of detection (LLD). The airborne indicator and CONTROL 1-131 REMP samples taken in 1999 at SONGS were statistically indistinguishable from zero.
Three samples yielded station related isotopic results above the a posteriori, MDC. Since a recount of these samples was less than MDC, we conclude that these results were false positives.
The quarterly composite gamma spectral analysis analyses yielded only naturally occurring beryllium-7 (Be-7) at the 3 sigma confidence level. For station related isotopes the balance of the airborne gamma isotopic database is statistically indistinguishable from database with zero activity.
We conclude that the operation of SONGS had no detectable impact on this sample medium.
25
Nonroutine Airborne Particulate, Iodine, and Composite Isotopic Analyses Air sampler 7, AWS Building Roof, is well within the Exclusion Area Boundary and is not required by the ODCM. This air sampler provides a basis for evaluating any airborne emissions that might impact workers in the major office area on the site. Those individuals are defined as members of the public according to 10 CFR 20.1003 and meet the dose limits of 10 CFR 20.1301. Air sample 7 was processed for particulate gross beta, 1-131, and quarterly composite gamma isotopic analysis. Results are included in Table B-3.
Air sampler 51, Blind Duplicate, is not required by the ODCM. The basis for this air sampler is found in Regulatory Guide 4.15. A sample duplicate program is recommended for those sample media yielding analysis results consistently above the a priori LLD. The only REMP sample category meeting this criteria is the airborne particulate gross beta. Air Sampler 51 is analyzed for gross beta only. A summary of the gross beta duplicate range control chart range data is included in Appendix C.
C.
Ocean Water Monthly ocean water samples were collected from indicator locations in the vicinity of each station discharge and from the CONTROL location at Newport Beach. The samples were analyzed for naturally-occurring and SONGS-related gamma-emitting radionuclides. Quarterly composite ocean water samples were analyzed for tritium according to ODCM requirements.
Naturally occurring potassium-40 (K-40) was detected in all ocean water samples obtained in 1999. No SONGS related radionuclides were detected in this sample medium during 1999.
Four non-routine ocean water samples were obtained from two locations, Unit 2 outfall conduit and Unit 3 outfall conduit. The conduit samples were collected to measure the radiological environmental effect potentially resulting from the minor conduit leakage Throughout 1999 only naturally occurring K-40 was detected at the 99% confidence level in the monthly gamma spectral analyses of ocean water. No station related radionuclides were detected above the aposteriori MDC in this sample type during 1999.
Excluding K-40 the ocean water gamma isotopic database is statistically indistinguishable from a database with zero activity.
The data indicate that SONGS operations had no measurable impact on this environmental medium.
D.
Drinking Water In 1999, drinking water samples were collected on a monthly basis from three indicator locations and from the Oceanside CONTROL location. Samples were analyzed for tritium, gross beta, and 28 naturally-occurring and SONGS-related gamma emitting radionuclides. There is no drinking water pathway for liquid effluent at SONGS.
One indicator sample in 1999 yielded a station related isotope (H-3) above the a posteriori MDC. Two recounts of this sample were below the MDC. This result appears to be a false positive.
26
Only gross beta was consistently detected at the 99% confidence level. The gross beta data indicate the CONTROL location typically had detectable gross beta and the indicator location often had no detectable gross beta activity. No station related radionuclides were detected in drinking water during 1999. Excluding gross beta, the drinking water gamma isotopic database is statistically indistinguishable from a database with zero activity. The operation of SONGS had no impact on this sample medium.
E.
Shoreline Sediment (Beach Sand)
Beach sand was collected semiannually in 1999 from three indicator locations and from a CONTROL location situated in Newport Beach. After collection, the samples were analyzed for 28 different plant-related and naturally-occurring radionuclides. Only naturally occurring K-40 and thorium-228 (Th-228) were detected at the 99% confidence level. No plant related radionuclides were reported above the a posteriori MDC. The operation of SONGS had no detectable impact on this sample medium.
F.
Ocean Bottom Sediments Ocean bottom sediments were collected in the vicinity of each of the three SONGS discharge locations and at the Newport Beach CONTROL location. The samples were analyzed by gamma-spectral analysis for 28 naturally-occurring and station-related radionuclides. K-40 and Th-228 were detected at the 99% confidence level in all ocean bottom sediment samples collected during 1999.
Four non-routine ocean bottom sediment samples were obtained from two locations, Unit 2 outfall conduit and Unit 3 outfall conduit. The conduit samples were collected to measure the radiological environmental effect potentially resulting from the minor conduit leakage. During 1999, all the conduit sample analysis results were below the MDC for station related radionuclides.
We conclude that the operation of SONGS had no significant effect on this sample medium.
G.
Non-Migratory Marine Species (Flesh)
Species of adult fish, crustacea and mollusks, were collected on a semi annual basis at the SONGS Unit 1 outfall, at the SONGS Units 2 and 3 outfall and from Laguna Beach. The flesh portion of each sample type was analyzed for 28 gamma-emitting station-related and naturally occurring radionuclides. The results were subsequently reported to Edison in terms of wet sample weights. Because results based on a wet sample weight are most useful for calculating doses, the results of sample analyses are summarized in terms of "as received" wet weights.
One indicator sample was slightly above the a posteriori MDC for Nb-95. Since the recount was less than MDC, this appears to be a false positive.
Naturally-occurring K-40 was detected in most samples at the 99% confidence level in all Marine Species samples collected during 1999. No plant related isotopes were reported above the a posteriori MDC. SONGS operations had no measurable impact on this environmental medium. The potential dose to members of the public from consumption of marine species near SONGS is not detectable.
27
H.
Local Crops Fleshy crops were collected semiannually in 1999 from the San Clemente Ranch, the SONGS garden, a San Clemente residence, and from a CONTROL location near Oceanside. The crop samples were analyzed quantitatively for 28 gamma-emitting radionuclides, both natural and plant related.
Naturally occurring Be-7 and K-40 were detected at the 99% confidence level in samples obtained from both CONTROL and indicator locations. No SONGS related isotopes were reported above the a posteriori MDC. Based on these data, it was concluded that SONGS operations had no detectable impact on this environmental medium and that the potential dose to members of the public from consumption of crops near SONGS is negligible.
L Soil To determine if there is evidence of a build-up of radionuclides in the land near SONGS, indicator soil samples were collected from the East Site Boundary (Former Visitor's center), Old Route 101, Basilone Road, and Camp San Onofre. A CONTROL sample was obtained from Oceanside. Surface soil was collected from all indicator and CONTROL locations at the depth of 3 inches. The sampling protocol is consistent with the procedure described in HASL-300.
Soil sampling is not required by ODCMs.
Soil samples were analyzed for 28 naturally-occurring and SONGS-related gamma-emitting radionuclides using gamma spectral analysis. All 1999 soil samples yielded naturally occurring K-40 and Th-228 above the 3 sigma (99%) confidence level. Cs-137, above the 99% confidence level, was detected in two indicator samples. Cs-137 is often detected in environmental sediment samples and the presence of Cs-137 is most likely related to nuclear weapons testing fallout.
Cs-137 and strontium-90 (Sr-90) were detected in soil profile analyses conducted in previous years. These radionuclides are mostly due to the nuclear weapons testing fallout depositing on soil and retention of these radionuclides due to their long half lives. The presence of Cs-137 in the CONTROL location in previous years supports the conclusion that the major source of this radionuclide is due to fallout deposition. Since the termination of atmospheric nuclear weapons testing the trend has continued downward in this sample media. Refer to the 1993 AREOR for a more detailed discussion of Cs-137 and other potentially SONGS related isotopes detected in soil. The Cs-137 activity can be attributed to atmospheric nuclear weapons tests and not SONGS operations. During 1999, SONGS had a negligible impact on this sample medium.
J.
Kelp Sampling Kelp was collected during April and October 1999 from the San Onofre, San Mateo, and from the Salt Creek alternate CONTROL location (- 10 miles WNW). Upon collection, the samples were analyzed by gamma-spectral analysis for 28 different naturally-occurring and Station-related radionuclides. The radionuclides detected in 1999 were K-40 and 1-131. K-40 is naturally occurring and not related to the operation of SONGS. 1-131 was detected in two indicator locations, as well as the alternate CONTROL location. 1-131 is often detected in Sewage Plant outfalls, including those routed to the Pacific Ocean. 1-131 has been detected at both Indicator and CONTROL locations in previous years. The northern CONTROL location is too far away and in the predominantly upstream current direction for the 1-131 activity to be attributable to SONGS. The presence of low levels of 1-131 in both the indicator and the control locations suggest a source which is external to SONGS. The 1-131 activity in Kelp data, graphically presented in Figure 4, shows a relatively close correlation between indicator and 28
control locations over a 25 year period - further supporting the assessment that the likely source for this potentially plant related radionuclide is external to SONGS.

APPENDIX C
SUMMARY
OF 1999 QUALITY CONTROL PROGRAMS 72
All REMP samples are collected, shipped, and analyzed in accordance with NRC Regulatory Guide 4.15. Marine radiological environmental samples are collected by a vendor, Ogden Environmental Services, per the vendor's Quality Assurance manual. REMP sample analysis is performed by the Contracted Environmental Analysis Laboratory (CEAL) in accordance with the Laboratory Quality Assurance Plan. During 1999 the CEAL was Duke Engineering Services.
INTERLABORATORY CROSS-CHECK PROGRAM:
The CEAL participates in a number of independent cross check programs, including the NIST and Analytics cross-check programs. A summary of the available 1999 Analytics cross check data is included in Table C-1. The CEAL's performance meets the criteria described in Reg Guide 4.15. The acceptance criteria was met for nearly all cross-check samples. Discrepancies were resolved by the CEAL through a formal condition report evaluation process.
SPLIT SAMPLING PROGRAM WITH DHS The California Department of Health Services (DHS) supervises the performance of split and duplicate sampling of selected media at the NRC licensed nuclear power plants in California. Radiochemical analysis is performed by the Sanitation and Radiation Laboratory (SRL); TLD processing is performed by a contractor. According to the 1997 report, there are no discrepancies between the DHS data and SONGS' data.
BLIND DUPLICATE QUALITY CONTROL SAMPLES In accordance with the protocol outlined in Reg Guide 4.15 SONGS conducted a blind duplicate sampling program using the gross beta particulate in air media. Data for the range chart quality control limits was generated using a duplicate air sampler co-located alternately with Air Sampler # 9.
Range control limits, acceptance criteria, and sampling frequency were established in accordance with the procedure described in Standard Methods.* For all of 1999 the duplicate results met the acceptance criteria. No adverse trends were observed.
COMPARISON OF TLD AND PIC DATA The SONGS REMP measures direct radiation at the various indicator and CONTROL locations with Thulium doped CaSO4 Panasonic Thermoluminescient Dosimeters (TLDs). The TLDs are collected quarterly and the corresponding dose is measured by the contracted laboratory. Transit dose and fade is compensated for in the reported results. A number of the REMP TLDs are located adjacent to Pressurized Ion Chamber (PIC) direct radiation dose rate meters. Data from the PICs is fed into a central processing unit with readouts near the control room. The PICs serve to provide real time monitoring of the radiation dose rates in the inner ring of SONGS. PIC data from the third and fourth quarters of 1999 were assembled and the average dose rate was converted to a quarterly total dose.

CALIBRATION OF AIR SAMPLER VOLUME METERS The Shop Services and Instrumentation Division of SCE performs an annual calibration procedure using standards referenced to NIST on all REMP air sampler gas meters. The acceptance criterion is
+/- 5% of the known volume. When the gas meters are removed from service, the meter is calibrated and the calibration reports are reviewed for bias. This is an a posteriori review of the gas meter performance to evaluate method bias and to identify possible outlier analysis results. In 1999 four (4) out of fourteen (14) gas meters failed to meet this criterion at all calibrated flow rates. Two gas meters were removed from service because they became inoperable. The volumes were estimated based on the average volume of the previous three weeks. A review of the affected gross beta data has revealed no meaningful anomalies. Thus no discemable impact to the REMP database or conclusions resulted from use of the inoperable and out of tolerance gas meters.
SONGS has taken action to resolve the issue of inoperable and or out of tolerance gas meters.
Replacement electronic mass flow meters have been installed.

APPENDIX D COMPARISON OF OPERATIONAL TO PREOPERATIONAL DATA AND ANALYSIS OF TRENDS 79
Comparison of Operational to Preoperational Data and Analysis of Trends Unit 1 became critical on June 14, 1967 and was permanently retired from service on November 30, 1992. Unit 2 attained initial criticality on July 26, 1982. Unit 3 attained initial criticality on August 29, 1983. Unit 2 was operating for all of 1999 except during a 54 day refueling outage. Unit 3 underwent a 46 day refueling outage and operated the remainder of the year.
A variety of environmental samples were analyzed and the analytical results (January 1, 1979 to July 31, 1982) were compared with the 1999 operational data obtained for SONGS Units 2 and 3, which is the subject post-operational period for SONGS Unit 1.
The following media were evaluated and compared with the operational data of SONGS Units 1, 2 and 3:
A.
External Radiation F.
Ocean Bottom Sediments B.
Air Particulates G.
Marine Species C.
Radioiodine H.
Local Crops D.
Ocean Water I.
Soil E.
Shoreline Sediment (sand)
J.
Kelp K.
Drinking Water All of the measurements obtained from the SONGS Unit 1 operational Radiological Environmental Monitoring Program (REMP) during the period from January 1979 to July 1982 are used as the preoperational baseline for SONGS Units 2 and 3. This is in accordance with San Onofre Units 2/3, Environmental Report, Operating License Stage, Appendix 6A, Pre operational Radiological Environmental Monitoring, May 31, 1978. Comparisons of preoperational data to 1999 operational data are possible for each of the exposure pathways to man, namely: (1) direct radiation, (2) air particulates (inhalation), and (3) ocean water (waterborne). Comparisons can also be made between preoperational and operational data for ocean bottom sediment data to ascertain if there has been any significant increase in radioactivity in ocean bottom sediments in the vicinity of the SONGS Units 2 and 3 outfalls.
A.
Direct Radiation SONGS Unit 1:
No direct radiation data were obtained in the preoperational period of 1964 to 1967 to compare with the operational data.
SONGS Units 2 and 3:
Direct radiation measurements were made quarterly at 50 indicator locations and 11 CONTROL locations in 1999. Direct radiation samples (TLDs) were collected at a number of inner and outer ring locations as specified by the ODCMs. During the preoperational period from January 1979 to July 31, 1982, the indicator stations ranged from 16.1 to 46.6 millirem.
80
The preoperational indicator average was 25.3. The preoperational CONTROL range was 19.3 to 30.1 and the CONTROL mean was 23.1. During the 1999 operational year for Units 2 and 3, the indicator TLD locations ranged from 9.0 to 27.6 millirem, averaging 15.6 millirem while the CONTROL locations ranged from 11.9 to 19.5 millirem with an average of 14.8 millirem.
Factors such as meteorology, geographic location, the fallout from atmospheric nuclear weapons testing, and seasonal fluctuations account the variability in the data seen during the preoperational period for each location. The decrease in radiation levels at all TLD sample locations is attributable to the curtailment of the atmospheric nuclear weapons testing, and the continued decay fission products from previous nuclear weapons tests.
The range of quarterly direct radiation doses was larger at both indicator and CONTROL locations during the preoperational period than during the 1999 operational period for SONGS Units 2 and 3. The larger range observed during the preoperational time span may be attributable to Communist Chinese atmospheric nuclear weapons tests on March 14, 1978 and on October 15, 1980. The large range of annual direct radiation levels seen at all TLD sample locations during 1986 and 1987 is attributable to the Chernobyl Nuclear Power Plant accident that occurred April 26, 1986.
Figures 2A & 2B compare the environmental radiation levels of selected indicator and CONTROL locations during the operational and preoperational periods. From 1979 to 1999 a decreasing trend can be observed, due to the curtailment of atmospheric nuclear weapons testing and the decay of residual fallout. Simultaneous variation in the radiation levels at both the CONTROL and indicator locations show that the variations are due to factors external to SONGS. The operation of SONGS had no detectable impact on this sample medium.
B.
Air Particulates SONGS Unit l.
Before SONGS Unit 1 attained initial criticality, samples of air particulate gross beta activity were collected from indicator and CONTROL locations. During the preoperational period of 1964-1967, detectable gross beta activity at the indicator locations ranged from 0.030 to 3.8 10 pCi/m3, averaging 0.253 pCi/m 3. The CONTROL location of Huntington Beach (HBGS) had an average gross beta activity of 0.306 ranging from 0.04 to 2.77 pCi/m3. During 1999, the gross beta activity at the indicator locations ranged from 0.0073 to 0.075 pCi/m3, and averaging 0.024 pCi/m3. The Oceanside CONTROL location gross beta activity ranged from 0.010 to 0.066 pCi/m 3 with an average of 0.024 pCi/m3. The decrease in activity levels between 1965 and 1999 is ascribed to the curtailment of atmospheric nuclear weapons testing and the resultant decrease in fallout.
Valid comparisons of preoperational data to the 1999 postoperational data are difficult to make because the preoperational background levels are elevated by a factor of about ten due to the atmospheric nuclear weapons testing fallout.
81
SONGS Units 2 and 3:
From January 1979 through July 1982 (considered to be the preoperational period for SONGS Units 2 and 3), there is a period of noticeably higher gross beta activity in air at all sample locations. This period extends from the fourth quarter of 1980 through the fourth quarter of 1981. These higher activity levels are attributable to the Communist Chinese atmospheric nuclear weapons test conducted on October 15, 1980.
Figures 3A and 3B compare the monthly average gross beta particulate in air activity levels of selected indicator locations with the CONTROL location over a period of 24 years (January 1976 to December 1999). The data clearly show a close correlation between the indicator and control locations for the entire time period covered. The various spike increases in gross beta activity at all sample locations are closely grouped and timed to coincide with known events external to SONGS with worldwide radiological impact. These events include: Communist Chinese atmospheric nuclear weapons testing on September 17, 1977; March 14, 1978; October 15, 1980; and the April 1986 Chernobyl accident. The graphs (Figures 3A and 3B) show that the environmental levels of gross beta remained substantially similar at both the indicator and the CONTROL locations over an extended period of time, with both CONTROL and indicator locations showing simultaneous variations of equal magnitude. The fluctuations in gross beta activity are not attributable to SONGS and are the result of other environmental phenomena and seasonal variations.
The Communist Chinese testing of October 1980 deposited a large amount of radioactivity in California and raised the background level. During this period the highest gross beta activity was observed at the Huntington Beach CONTROL station (0.29 pCi/m3 on the collection period ending May 11, 1981). The dispersion of the radioactive plume and its travel throughout the country affected the environmental levels at all the locations being studied. The fallout from the weapons testing raised the background radiation level in this sample medium by approximately one order of magnitude. The decrease in gross beta activity level after mid-1981 is ascribed to the curtailment of the Chinese weapons testing. Since the end of the weapons testing the overall trend of the data has been a decrease in the annual average gross beta particulate in air activity to a level of approximately 0.02 pCi/m3.
The average activity in all the indicator locations during operational period of January to December 1999 was 0.034 pCi/m&. During 1999 the CONTROL average was 0.024 pCi/m3.
There is a close correlation between the weekly indicator and CONTROL gross beta activity during 1999. Refer to Figures 3C. The operation of SONGS has had no detectable impact on this sample medium.
C.
Radioiodine SONGS Unit 1:
No preoperational data is available. All 1999 data was below both the aprioni LLD (0.07 pCi/m3) and the lower, count specific, a posteriori MDC.
82
SONGS Units 2 and 3:
Most of the preoperational and all of the 1999 operational data for 1-131 level were below the detection limit.
D.
Ocean Water SONGS Unit 1:
No samples were obtained for the preoperational period of SONGS Unit 1.
SONGS Units 2 and 3:
Ocean water samples were collected on a monthly basis in the vicinity of each of the Station discharge outfalls, which served as indicator locations and from the Newport Beach CONTROL location. The ocean water samples are analyzed for naturally-occurring and station-related gamma-emitting radionuclides. They are composited quarterly and analyzed for tritium.
During the preoperational period, naturally-occurring potassium-40 was detected in each of the samples collected from both indicator and CONTROL locations. Other gamma-emitting radionuclides were detected in only one ocean water sample. In May 1980, Co-58, Co-60, Cs-134, and Cs-137 were detected in an ocean water sample collected from the SONGS Unit 1 outfall. Concentrations of the radionuclides in this sample were 11, 6, 380, and 430 pCi/l, respectively. Tritium was also detected in two of the ocean water samples collected in May 1980 from the SONGS Unit 2 outfall and from the Newport Beach CONTROL location.
Reduction in effluent activity through programmatic changes at Unit 1 may have reduced activity levels in ocean water.
For tritium and all SONGS related radionuclides the data collected at all locations during the 1999 operational period was below both the a priori LLD and the lower a posteriori MDC. We conclude that the operation of SONGS has had a negligible impact on this sample medium.
E.
Shoreline Sediments (Sand)
SONGS Unit l:
Shoreline Sediment samples were not collected during the preoperational period for SONGS 1.
SONGS Units 2 and 3:
Beach sand is collected semiannually from three indicator locations and from a CONTROL location situated at Newport Beach. The samples are analyzed for 28 naturally-occurring and plant-related radionuclides.
To assess the impact of SONGS operations on this environmental medium, preoperational data were compared to 1999 operational data. The radionuclide detected in shoreline sediment in the preoperational time frame was Cs-137 with a range of 0.012 to 0.022 pCi/g, averaging 0.019 in 83
5 sediment samples. One CONTROL sample with a Cs-137 activity of 0.032 pCi/g was observed in July 1979. The presence of Cs-137 in both CONTROL and indicator locations during the preoperational period leads to the conclusion that the root cause is external to SONGS and is most likely attributable to Communist Chinese atmospheric nuclear weapons testing. No SONGS-related radionuclides were detected in shoreline sediment during the 1999 operational period, thus the impact of SONGS on this environmental medium is considered to be negligible.
F.
Ocean Bottom Sediments SONGS Unit 1:
Ocean bottom sediment samples were not collected during the preoperational phase of Unit 1, and, therefore, no comparison can be made. However, operational data for SONGS 1 did not reveal the presence of any significant radioactivity in the sediment samples.
SONGS Units 2 and 3:
During the preoperational and operational periods, representative samples of ocean bottom sediments were collected semiannually from each of the Station discharge outfalls and from a CONTROL station in Laguna Beach. The samples were analyzed for naturally occurring and SONGS related radionuclides. The results of the analyses are listed in Table D-lB. It is clear in surveying the data that the concentration of each of the radionuclides has decreased with time or has been consistently below the lower limit of detection.
SONGS-related radionuclides were also detected in samples collected during preoperational period. Manganese-54 (Mn-54) was detected in 5 of the 28 samples. The concentrations of Mn-54 in these samples ranged from 0.015 to 0.49 pCi/g, averaging 0.13 pCi/g. Cobalt-58 (Co-58) was detected in nine samples. The concentration of Co-58 in the samples ranged from 0.013 to 1.16 pCi/g, averaging 0.20 pCi/g. Cobalt-60 (Co-60) was measured in 15 of the 28 samples. The concentration of Co-60 in the sample ranged from 0.014 to 8.1 pCi/g, averaging 0.79 pCi/g. Cs-137 was also detected in 16 of the 28 samples. The concentrations of Cs-137 in the samples ranged from 0.014 to 0.090 pCi/g, averaging 0.039 pCi/g. Cerium-144 (Ce-144) was found in two samples. The concentration of Ce-144 in the samples was 0.06 and 0.26 pCi/g, respectively.
The results indicate that there has not been a build-up of radionuclides with time in ocean bottom sediments near SONGS. The results also indicate notable decrease in the concentrations of plant-related radionuclides in the ocean bottom sediment. Although Co-58, Co-60, silver-lOim (Ag-11Om), and Cs-137 are normally associated with nuclear power operations, preoperational study reveals no accumulation trend for these radionuclides, and no increase in levels for these radionuclides was detected during the operational period.
The concentration of station-related radionuclides in all ocean bottom sediment samples analyzed in 1999 was below the apriom LLD as well as below the lower aposteriori MDC. We conclude that operation of SONGS Units 2 and 3 has had a negligible impact upon this environmental medium.

Marine Species (Flesh)
SONGS Unit 1:
Marine species were not collected during the preoperational period for SONGS Unit 1. No comparison with operational data is possible.
SONGS Units 2 and 3:
Non-migratory marine species were collected semi-annually near SONGS to determine the amount of radioactivity that could be consumed by man or in the food chain to man. Marine species caught by the SONGS outfalls and from Laguna Beach include two species of adult fish, crustacea and mollusks. Upon collection, the flesh portion is analyzed for gamma-emitting, radionuclides as specified in the ODCM. The results are subsequently reported as pCi/gram wet weight.
Results for several marine species for both the preoperational and 1999 operational periods for Units 2 and 3 are summarized in Table D-2. The marine species used for purposes of comparison include: sheephead (a fish), black perch (a fish), bay mussel (a mollusk), spiny lobster (a crustacea), sea hare (a mollusk), and keyhole limpet (a mollusk). Radionuclides analyzed but not included in Table D-2 were below the lower limits of detection for both the preoperational and operational periods.
During the 1999 operational period, no SONGS related radionuclides were detected at either the a priori LLD or the lower a posteriori MDC. The data indicate no accumulation trends. The operation of SONGS Units 2 and 3 in 1999 has had no measurable impact on this environmental medium.

Local Crops SONGS Unit 1:
During the preoperational phase of Unit 1, local crops were collected semiannually from both indicator and CONTROL locations, and subsequently analyzed for Sr-90. The range was 0.008 to 0.030 pCi/g wet weight. The average Sr-90 value was 0.022 pCi/g wet weight. Sr-90 is a common fission product likely due to atmospheric weapons tests.
During the 1999 operational period only naturally occurring radionuclides were detected in the crop samples.
SONGS Units 2 and 3:
In the preoperational period of January 1979 through July 1982, Sr-90 was detected in the CONTROL samples of kale, parsley, and squash. Naturally occuring K-40 was detected in cucumber, kale, and tomato samples from the indicator and CONTROL locations. Ce-144 and Zr-95 were detected in one sample of parsley at the CONTROL location at concentrations of 0.12 and 0.09 pCi/g, wet weight respectively.
In the 1999 operational period, only naturally occurring radionuclides were detected in the crop samples. The data indicate that the concentration of SONGS related radionuclides have decreased over time in this sample medium. This decrease is attributable to the termination of atmospheric nuclear weapons testing. The operation of SONGS has not had a measurable impact on this medium.
I.
Soil SONGS Unit 1:
No soil data were available for Unit 1 preoperational phase so a comparison cannot be made.
However, gamma isotopic analysis of soil does not show any significant level of radioactivity.
No accumulation pattern of plant-related radionuclides in the soil has been observed in the last 20 years.
SONGS Units 2 and 3:
A comparison of operational and preoperational data does not reveal any accumulation pattern of SONGS related isotopes in soil. The intermittent detection of Cs-137 in both indicator and CONTROL locations is due to residual fallout from atmospheric nuclear weapons testing.
90
J.
Kelp SONGS Unit 1:
Samples of kelp were not collected and analyzed during the preoperational period for SONGS Unit 1. No comparison with operational data is possible.
SONGS Units 2 and 3:
Kelp is collected semiannually from three indicator locations and from a CONTROL location situated in Laguna Beach. After collection, the samples are analyzed by gamma-spectral analysis for naturally-occurring and SONGS-related radionuclides.
To assess the impact of SONGS operations on kelp, preoperational data were compared to 1999 operational data in Table D-4. Radionuclides detected during the preoperational period for SONGS Units 2 and 3 include Mn-54, Co-60, Zr-95, 1-131, and Cs-137.
During the 1999 operational period, 1-131 was detected in six (6) samples obtained. No other station related isotopes were detected in kelp samples during the 1999 operational period. Figure 4 (1-131 in Kelp) shows a close correlation between indicator and control sample locations over a 25 year period.
Although 1-131 activity has been randomly detected in kelp since 1977, there is no evidence that the concentration of 1-131 or other station related radionuclides in kelp is increasing near SONGS. 1-131 in kelp is most likely due to the sewer release of medical administrations, since it has been detected consistently in CONTROL as well as indicator locations. Since 1988 the concentration of 1-131, when detected, has typically been highest at the CONTROL location.
This data supports the conclusion that during the Units 2/3 operational period, the detection of 1 131 in kelp is primarily due to factors external to SONGS.
K.
Drinking Water No plant related radionuclides were detected during the 1999 operational period. Gross beta activity was detected during both the operational and preoperational periods at both the indicator and the CONTROL locations. No trends have been noted. There is no drinking water pathway for SONGS. The operation of SONGS has had no detectable impact on this sample media.

APPENDIX E DEVIATIONS FROM ODCM SAMPLING REQUIREMENTS IN 1999 93
DEVIATIONS FROM THE ODCM SAMPLING REQUIREMENTS Deviations from the Offsite Dose Calculation Manual (ODCM) sampling requirements are identified below in accordance with section 5.0 of the ODCM. The performance standard for environmental data collection of 95% was met for all sample types. During 1999 the ODCM specified a priori LLD was achieved for every REMP sample obtained. Deviations from the ODCM were associated with external factors not within the control of REMT personnel such as limited availability of Marine Samples at the locations specified in the ODCM. These minor unavoidable deviations from the ODCM had no meaningful impact on the REMP database and did not compromise the validity of the reported conclusions.
_I 94
TERRESTRIAL SAMPLING A.
WEEKLY AIR SAMPLING Downtime for each air sampler in 1999 due to weekly sample collection, annual preventive maintenance (PM) and the annual gas meter change out was approximately 46 minutes for each sampler.
Weekly Change out:
Annual PM:
Annual Gas Meter change out:
Approximately 0.5 minutes x 52 = 26 minutes Approximately 15 minutes Approximately 5 minutes Down times in excess of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> are described below for each air sample. Air sampler availability remains well above 95%.
Air Sampler 1 (City of San Clemente):
During the collection period ending July 20, 1999, particulate and iodine samples were not collected at this location. The discrepancy was resolved by the SONGS event reporting process.
This resulted in a subsequent 14 day collection cycle ending July 27, 1999.
Air Sampler 9:
No deviations were observed.
Air Sampler 10 (Bluff):
No deviations were observed.
Air Sampler 11 (EOF):
No deviations were observed.
Air Sampler 12 (Former SONGS Evaporation Pond):
No deviations were observed.
Air Sampler 13 (Camp Pendleton East):
No deviations were observed.
95 PART I
Air Sampler 14 (Mesa Medical Facility):
No deviations were observed.
Air Sampler 15 (Oceanside CONTROL):
No deviations were observed.
Summary of Air Sampler Corrective Actions The useful life of the vacuum pump motor assemblies is estimated to be five years based on the recommendation of the manufacturer and upon experience. If the internal components (motor and control valve) are replaced the useful life may be extended. During 1999 the REMP air samplers experienced no down time attributable to motor or vacuum pump assembly failure.
B.
DIRECT RADIATION A brush fire near TLD 36 partially melted the plastic TLD canister during the second quarter of 1999. The TLD was processed and the data appeared to be normal.
During the second quarter of 1999, TLD 75 was missing. Vandalism is suspected. A replacement canister was installed nearby in a less visible location.
During the third quarter of 1999, TLD 46 was missing. Again, vandalism is suspected. A replacement canister was installed in a less conspicuous location nearby.
C.
LOCAL CROPS No deviations were observed.
D.
SHORELINE SEDIMENTS No deviations were observed.
E.
DRINKING WATER No deviations were observed.
F.
SOIL No deviations were observed.
96
PART II MARINE SAMPLING A.
NON-MIGRA TORY MARINE ANIMALS Samples were collected from the specified ODCM sample location when samples were available at that location. When the specified sample type was not available at the ODCM listed location alternate locations were selected based on sample availability and proximity to the specified sample location. All indicator samples were obtained within two miles of the associated outfall.
In some cases the indicator species is not the same as the control species due to limited availability at the indicator location.
Samples were obtained from the following locations relative the midpoint of Units 2/3 during 1999:
Sample A Unit 1 lobster Sample A Unit 1 kelp bass and sheephead Sample A Unit 1 aplysia (sea hare)
Sample B Units 2/3 lobster Sample B Units 2/3 sheephead & kelp bass Sample B Units 2/3 mytilus (bay mussel)
Sample C North CONTROL all species Sample A Unit 1 (lobster, sheephead, and black perch)

0.9 miles WSW 1.5 miles SSW 18.2 miles NW B.
OCEAN WATER SAMPLING Sample A Outfall-Unit 1 All samples taken 0.6 miles SW (No deviations) 97 April 1999 April 1999 April 1999 October 1999 October 1999
Sample B Outfall-Unit 2 The monthly 1999 ocean water samples were taken in the range of 1.4 to 1.6 miles SW. Unit 2 outfall is through an extended diffuser line which is about 0.5 miles long, stretching from approximately 1.1 to 1.6 miles from SONGS. The diffuser line is located in Sector L (SW) very close to the border of Sector M (SSW). All 1999 samples were taken close to the Unit 2 discharge and meet the intent of the RETP sampling requirements.
Sample C Outfall-Unit 3 The 1999 ocean water samples were taken in the range of 1.2 to 1.3 miles SSW. The Unit 3 diffuser portion of the outfall extends approximately 0.7 miles to 1.2 miles from the midpoint of Units 2/3. The samples were obtained from an area very close to the Unit 3 diffusers. The intent of the REMP indicator sampling requirements were met.
Sample D Newport Beach (CONTROL)
The 1999 samples were taken in the range of 27.3 to 30.1 miles NW. The purpose of this CONTROL sample is to obtain a background sea water sample far enough from SONGS to be completely unaffected by the operation of SONGS. The samples collected during 1999 satisfied this goal and met the intent of the REMP requirements.
The ODCM Specified locations for ocean water samples are as follows:
Sample A Station Discharge Outfall Unit 1 0.6 miles SW Sample B Outfall Unit 2 1.5 miles SW Sample C Outfall Unit 3 1.2 miles SSW Sample D Newport Beach (CONTROL) 30.0 miles NW C.
OCEAN BOTTOM SEDIMENTS Sample A Unit 1 Outfall - The April 1999 sample was obtained 0.7 miles SSW from Units 2/3 midpoint. The October 1999 sample was obtained 0.6 miles W.
Sample B Unit 1 Outfall - The April 1999 sample was obtained 0.7 miles WSW. The October 1999 sample was obtained 0.8 miles SSW.
Sample C Unit 2 Outfall - The April 1999 sample was obtained 1.5 miles SW. The October 1999 sample was obtained 1.6 miles SW.
Sample D Unit 3 Outfall - The April 1999 sample was obtained from a location 1.0 miles SSW.
The October 1999 sample was obtained from a location 1.2 miles SWW.
Sample E Laguna Beach (CONTROL) - Both the April and October 1999 samples were obtained from a location 17.1 miles NW.
98
Actual sample location depends on sediment availability which is a function of seasons, currents, and other macro environmental factors. The actual exact sample location has been determined for each of the past three years via a Differential Global Positioning System (DGPS) receiver.
When sufficient DGPS data is available the approximate location of the sites associated with most frequently assessable ocean bottom sediment samples will be incorporated into the ODCM.
The ocean bottom sampling is performed only twice per year; sufficient data is expected to be available in 2001.
D.
KELP Sample A San Onofre Kelp Bed - The April 1999 kelp was not available in April 1999 at the San Onofre Kelp Bed. The October 1999 sample was obtained from a location 1.4 miles S from Units 2/3. The ODCM specified location is 1.5 miles S.
Sample B San Mateo Kelp Bed - The April 1999 sample was obtained from a location 3.1 miles WNW from Units 2/3 midpoint. The October 1999 sample was obtained from a location 3.1 miles WNW from Units 2/3 midpoint. The ODCM specified location is 3.8 miles WNW.
Sample C Barn Kelp - The Barn Kelp Bed was not present in April 1999. The October 1999 sample was obtained 6.0 miles SSE from the midpoint of Units 2/3. The ODCM location is 6.3 miles SSE.
Sample D Laguna Beach (CONTROL) - The Laguna beach bed was not in bloom during 1999.
A CONTROL sample was obtained from the Salt Creek alternate CONTROL location.
The April 1999 sample was obtained 11.5 miles WNW. The October 1999 sample was obtained 11.5 miles WNW. The ODCM specified location is 15.6 miles NW.
Kelp is intermittently available at the various local kelp forests. Sea urchin population, El Nino and La Nina weather phenomena and other macro-environmental factors determine Kelp sample availability. Samples were obtained from the kelp canopy closest to the ODCM specified location.
99
PART HI NON ROUTINE SAMPLES OBTAINED DURING 1999 Direct Radiation Samples:
In order to ensure verbatim conformity with the SONGS Emergency Plan (E Plan) a number of TLDs were deployed around SONGS during 1999 to bring the total number of TLDs up to the number specified in the E Plan. TLDs EP79, EP80, EP81, EP82, EP83, EP84, EP85, and EP86 were deployed in locations along Basilone Road and along the Old Highway 101 near the SONGS high voltage transmission lines. These TLDs were not used to meet any REMP or ODCM related sampling goal. Data from these TLDs are included in Table B-3.
Air Samples:
Air sampler 7 provides a basis for evaluating any airborne emissions that might impact workers in the major office area at SONGS. Air sampler 51 was installed to provide a duplicate gross beta sample in accordance with Reg. Guide 4.15.
Air Sampler 7 AWS Roof 0.2 miles NW Air Sampler 51 Blind Duplicate 0.6 miles ESE Ocean Water and Ocean Bottom Sediment Samples:
There is a minor leak in both the Unit 2 and Unit 3 outfall conduit. In order to ensure that no detectable radiological environmental impact results from this discharge, ocean water and an ocean bottom sediment sample were obtained from near the vicinity of each leak. Data from these samples is included in Table B-3.

APPENDIX F LAND USE CENSUS 101
INTRODUCTION Southern California Edison conducted the annual 1999 Land Use Census (LUC) in accordance with section 5.2 of the Offsite Dose Calculation Manual (ODCM). The purpose of the LUC is to identify important radiological pathways to humans. The LUC identifies the nearest residences, milk animals, meat animals, gardens of at least 500 square feet that produce fleshy or leafy vegetables, and other specified uses (campgrounds, employment, etc.) in each of the meteorological landward sectors within five miles of SONGS. Results are summarized in Table F-I and F-2 at the end of this appendix.
THE STUDY AREA The study area includes half of the city of San Clemente (population estimated at 49,250 as of January 1, 1999), the San Clemente State Park, U.S. Marine Corps Base Camp Pendleton (MCB), San Onofre State Beach and Park, the San Clemente Ranch, the former U. S. Coast Guard Station at San Mateo Point, and SONGS.
METHODOLOGY A review of the 1998 LUC and documentation notebook was conducted. Verification and revision of the 1998 data was accomplished by inquiry to the cognizant agency, organization, or individual possessing direct knowledge of the item being verified.
The garden census was performed by examining aerial photographs taken June 9, 1999. The photographic image areas which appeared to correspond to likely garden locations were converted to street addresses. The identified locations and residences were visited and the occupants interviewed to determine if a vegetable garden was present. Four (4) previously unidentified gardens (> 500 sq ft) growing leafy vegetables were identified within the study area.
Edison personnel planted a garden on site to ensure sample availability.
The closest residence was established in each sector by correspondence with cognizant authorities (City of San Clemente Planning Department and USMC Camp Pendleton). The meat and milk animal survey was performed by contacting the natural resources office on Camp Pendleton. Information on other uses was obtained by contacting the appropriate organizations.
DEFINITIONS Residence is defined as any structure (single-family house, apartment, mobile home, barracks or similar unit) occupied by individual(s) for three months (2,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />) or longer per year.
Other Specified Use is defined as a location occupied by members of the general population as other than their primary residence. The use is divided into two categories: employment and non employment related.
102
Employment use is defined as a location occupied by members of the general population engaged in normal work activities regardless of the length of time spent at the location, and regardless of its permanence, including concession stands, restaurants, markets and guard shacks.
Non-employment-related use is defined as a location occupied by members of the general population who are not engaged in normal work activities, including campgrounds, temporary housing, time-share condominiums, motels, hotels, schools and beaches.
Milk animals include, but are not limited to cows, goats and sheep, whose milk is used in dairy products for human consumption.
Meat animals include, but are not limited to deer, other game animals, cattle, goats and sheep, whose meat is used for human consumption.
Leafy vegetables include, but are not limited to lettuce, cabbage, collard greens, Bok choi, sorrel, and spinach.
Fleshy vegetables include, but are not limited to tomatoes, cucumbers, cauliflower, squash, beans, zucchini, and sweet com.

APPENDIX I REMP TLDs CO-LOCATED WITH NRC TLDs During 1999 Requirements in the standard Technical Specifications adopted under the Technical Specifications Improvement Program include reporting results of those thermoluminescent dosimeters (TLDs) that are co-located with NRC, dosimeters. The NRC no longer deploys TLDs in the environs of SONGS. Some SCE TLDs are located adjacent to the former NRC TLD locations and these SCE TLDs are listed below.
The DHS also maintains a TLD program in the environs of SONGS. The DHS direct radiation monitoring program uses Radiation Detection Corporation (RDC) TLDs.
The below listed quarterly TLD data is from the SCE TLD program. NRC & RDC data are not listed. The NRC location numbers refer to the locations in the previous program, terminated before 1999.
