RADIOLOGICAL ENVIRONMENTAL SURVEY January 1 - December 31, 2003 1.0

SUMMARY

The Annual Radiological Environmental Operating Report is published in accordance with Section 5.0 of the Offsite Dose Calculation Manual, (ODCM).

This report describes the Radiological Environmental Monitoring Program, (REMP), and its implementation as required by the ODCM.

The REMP is implemented to measure radioactivity in the aquatic and terrestrial pathways. The aquatic pathways include Lake Ontario fish, Lake Ontario water, and Deer Creek water. Measurement results of the samples representing these pathways contained only natural background radiation or low concentrations of Cs-1 37 resulting from past atmospheric nuclear weapons testing.

Terrestrial pathways monitored included airborne particulate and radioiodine, milk, food products, and direct radiation. Analysis of terrestrial pathways demonstrated no detectable increase in radiation levels as a result of plant operation. The 2003 results were consistent with data for the past five years and exhibited no adverse trends.

The analytical results from the 2003 Radiological Environmental Monitoring Program demonstrate that the operation of the R. E. Ginna Nuclear Power Plant had no measurable radiological impact on the environment. The results also demonstrate that operation of the plant did not result in a measurable radiation dose to the general population above natural background levels.

During 2003,1230 samples were collected for analysis by gross beta counting and/or gamma spectroscopy. These included 929 air samples, 60 water samples, 18 fish samples, 6 sediment samples, 15 vegetation samples, 47 milk samples, and 155 thermoluminescent dosimeter measurements. During 2003 there were three deviations from the sampling schedule for air samples. The minimum number of samples required in ODCM Table 5-1 were collected for all pathways.

Samples were collected by Ginna Station chemistry personnel and analyzed by the J. A. Fitzpatrick Nuclear Power Plant Environmental Laboratory.

A summary of the data collected indicating the results of all data for indicator and control locations is given in Table 1-1.

2.0 PROGRAM DESCRIPTION 2.1 Program Objectives The objectives of the Radiological Environmental Monitoring Program are:

Measure and evaluate the effects of plant operation on the environment.

Monitor background radiation levels in the environs of the Ginna site.

Demonstrate compliance with the environmental conditions and requirements of applicable state and federal regulations, including the ODCM and 40 CFR 190.

Provide information by which the general public can evaluate environmental aspects of the operation of Ginna Nuclear Power Station.

2.2 Program Requirements In order to achieve the objectives listed in section 2.1, a sampling and analysis program is implemented each year according to table 5-1 of the ODCM.

Following are the requirements from the ODCM:

Monitoring Program The radiological environmental monitoring program shall be conducted as specified in Table 5-1 at the locations given in the ODCM.

If the radiological environmental monitoring program is not conducted as specified in Table 5-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report, a description of the reasons for these deviations and the plans for preventing a recurrence. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal availability, or to malfunction of automatic sampling equipment. If the latter, efforts shall be made to complete corrective action prior to the end of the next sampling period.

If milk or fresh leafy vegetable samples are unavailable for more than one sample period from one or more of the sampling locations indicated by the ODCM, a discussion shall be included in the Annual Radiological Environmental Operating Report which identifies the cause of the unavailability of samples and identifies locations for obtaining replacement samples. If a milk or leafy vegetable sample location becomes unavailable, the locations from which samples were unavailable may then be deleted from the ODCM, provided that comparable locations (if available) are added to the environmental monitoring program.

(3)

Land Use Census A land use census shall be conducted and shall identify the location of the nearest milk producing animal and the nearest residence in each of the 16 meteorological sectors within a distance of five miles.

An onsite garden located in either the meteorological sector having the highest historical D/Q, or in a location with a higher DIQ than the location of the maximally exposed individual, may be used for broad leaf vegetation sampling in lieu of a garden census. Otherwise the land use census shall also identify the location of the nearest garden of greater than 500 square feet in each of the 16 meteorological sectors within a distance of five miles. D/Q shall be determined in accordance with methods described in the ODCM.

Interlaboratorv Comparison Pro-gram Analyses shall be performed on applicable radioactive environmental samples supplied as part of an interlaboratory comparison program which has been approved by NRC, if such a program exists.

Specification The radiological environmental monitoring samples shall be collected pursuant to Table 5-1. Acceptable locations are shown in the ODCM. Samples shall be analyzed pursuant to the requirements of Tables 5-1 and 5-3.

A land use census shall be conducted annually between June 1 and October 1.

A summary of the results obtained as part of the required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Operating Report.

Deviations from the Sampling Schedule Deviations from the sampling schedule are allowed when samples are unavailable due to hazardous conditions, seasonal variations or malfunction of automatic sampling equipment.

Table 2-2 Page 2 of 2 LLD TABLE NOTATION The LLD is the smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal.

The LLD is defined as an apriori (before the fact) limit representing the capability of a measurement system and not as an aposteriori (after the fact) limit for a particular measurement, the minimum detectable activity (MDA).

For a particular measurement system (which may include radiochemical separation):

LLD = 4.66 Sb E V 2.22 Y exp(-XAt) where:

LLD is the lower limit of detection as defined above (as pCi per unit mass or volume) 4.66 establishes 95% confidence interval about LLD Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (in counts per minute)

E is the counting efficiency (as counts per disintegration)

V is the sample size (in units of mass or volume) 2.22 is the number of disintegrations per minute per picocurie Y is the fractional radiochemical yield (when applicable)

Xis the decay constant for the particular radionuclide At is the elapsed time between sample collection, (or end of sample collection period), and time of counting (8)

3.0 DATA

SUMMARY

3.1 Analytical Results The values listed on the following tables include the uncertainties stated as

+/- 1 standard deviation.

Definitions Curie (Ci): The quantity of any radionuclide in which the number of disintegrations per second is 37 billion.

Picocurie (pCi): One millionth of a millionth of a curie or 0.037 disintegrations per second Cubic meter (M3) Approximately 35.3 cubic feet Liter (L): Approximately 1.06 quarts Kilogram (Kg): Approximately 2.205 pounds Lower Limit of Detection The U.S. Nuclear Regulatory Commission has requested that reported values be compared to the Lower Limit of Detection (LLD) for each piece of equipment.

The LLD for the equipment is established by the measurement of a blank sample. These values are before correction for decay. Decay correction is applied from the end of the sampling period to the counting time, not from the midpoint of the sampling period. An explanation of the calculation of the LLD is included with Table 2-2, (page 8).

(13)

3.2 Air Samples Radioactive particles in air are collected by drawing approximately one SCUM through a two inch diameter particulate filter. The volume of air sampled is measured by a dry gas meter and corrected for the pressure drop across the filter. The filters are changed weekly and allowed to decay for three days prior to counting to eliminate most of the natural radioactivity such as the short half-life decay products of radon.

The decay period is used to give a more sensitive measurement of long-lived man-made radioactivity.

A ring of 6 sampling stations is located on the plant site from 150 to 420 meters from the reactor centerline near the point of the maximum annual average ground level concentration, I more is located on-site at 690 meters, and 2 others offsite at approximately 7 miles. In addition, there are 3 sampling stations located approximately 7 to 16 miles from the site that serve as control stations.

Based on weekly comparisons, there was no statistical difference between the Control and Indicator radioactive particulate concentrations. The averages for the control samples were 0.016 pCi/M3, and the averages for the indicators were 0.017 pCi/M 3 for the period of January to December, 2003. Maximum weekly concentrations for each station were less than 0.043 pCi/M3. These results include a worst case evaluation of two air sample gas meters which failed as-found tests on 2/11/03 and 5/14/03. The failed flows were 118% and 116% for indicator stations 13A and 6, respectively. See Section 7.0.

The major airborne species released from the plant are noble gases, tritium and radioiodines. Most of this activity is released in a gaseous form, however, some radioiodine is released as airborne particulate and some of the particulate activity is due to short lived noble gas decay products.

Tables 3-1A, 3-1B are a list of gross beta analysis values for the on-site sample stations. Tables 3-2A, 3-2B are a list of gross beta analysis values for the off-site sampler stations.

The particulate filters from each sampling location were saved and a 13 week composite was made. A gamma isotopic analysis was performed for each sampling location and corrected for decay. The results of these analyses are listed in Tables 3-4 A to D, and indicate only the naturally occuring radioisotopes, Be-7 and K-40.

(14)

Radioiodine cartridges are placed at six locations. These cartridges are changed and analyzed each week. No positive analytical results were found on any sample. A list of values for these cartridges is given in Table 3-5.

A trend plot of the 2003 Onsite vs. Offsite air filter data is included, Table 3-3.

Additionally, a trend plot of the annual averages measured since 1968, Table 3-6, is included to show the variation of data during the years that the R.E. Ginna Nuclear Power Plant has been operational. The peak activities measured correspond to the years when atmospheric tests of nuclear weapons were conducted.

3.3 Water Samples Water samples are collected on a schedule specified in the ODCM, from locations surrounding the plant to assess if there is any measurable influence upon, or contamination of, drinking or irrigation water from liquid effluent releases, or deposition from gaseous effluent releases.

Samples are collected weekly from Lake Ontario, upstream (Russell Station) and downstream (Ontario Water District Plant - OWD), composited monthly, and analyzed for gross beta activity, Table 3-8. There was no statistically significant difference between the upstream and downstream sample concentrations. The 2003 averages were 2.68 pCi/liter and 2.65 pCi/liter for the upstream and downstream samples respectively. Gamma isotopic analysis of the monthly composite samples showed no significant difference in activity between the upstream and downstream samples.

A graphical comparison of upstream vs downstream gross beta analysis results is given in Table 3-7A. Peaks up to 10 pCiliter can occur when the lake is stirred up by wind and the weekly sample includes large quantities of suspended silt. A trend plot, Table 3-7 B, showing the annual average activity measured during the years since 1968 is included to show the data during the years the R.E. Ginna Nuclear Power Plant has been in operation. The peaks correspond to the years when atmospheric testing of nuclear weapons occurred.

Weekly samples are taken from the plant circulating water intake (Circ In) and discharge canal (Circ Out), and composited monthly. The 2003 averages were 2.44 pCi/liter and 2.46 pCi/liter for the intake and discharge canal respectively. These are essentially the same as the upstream and downstream values as they fall within the

+/- 1 sigma error band and range of the measurement.

Results for all water beta analyses are listed in Table 3-8 .

Samples of the creek which crosses the site are collected and analyzed monthly.

Deer Creek gross beta values are typically higher than other surface water samples due to Radon progeny in the soils from which the creek recharges and over which the creek flows.

(26)

Isotopic Analysis Gamma isotopic analysis is performed on each monthly composite sample. These are listed in Tables 3-9 to 3-14 and are separated by source of sample. No anomalous results were noted.

Tritium Analysis Tritium analysis was performed on all water samples on a monthly basis.

Composites are made from the weekly samples and a portion filtered to remove interferences for analysis by beta scintillation. Tritium data is given in Table 3-15.

Radioiodine analysis All monthly composite water samples are analyzed for lodine-1 31. The analysis allows the determination of lodine-1 31 activity of <1 pCi/liter. Radioiodine data is given in Table 3-16. Any positive counts and the 1 sigma error are reported. During 2003, no sample results indicated 1-131 activity in excess of the LLD for the analysis.

3.4 Milk Samples There were two indicator dairy herds located three to five miles from the plant on 1/1/03. The owner of a third indicator farm retired early in 2002, and a change to the ODCM was submitted to reflect this. Milk samples are collected monthly during November through May from one of the indicator farms and biweekly during June through October from each. A control farm sample is taken for each monthly sample and once during each biweekly period. The milk is analyzed for lodine-131 and also analyzed by gamma spectroscopy for major fission products.

All positive counts and the +1 sigma error are reported. During 2003, no samples indicated 1-131 activity that exceeded the LLD for the analysis.

Table 3-17 is a listing of all samples collected during 2003 with analytical results.

3.5 Fish Samples Indicator fish are caught in the vicinity of the Discharge Canal and analyzed for radioactivity from liquid effluent releases from the plant. The fish are filleted to represent that portion which would normally be eaten. Additional fish are caught more than 15 miles away to be used as control samples and are prepared in the same manner.

Four different species of fish are analyzed during each half-year from the indicator and background locations if they are available. There was no statistically significant difference in the activity of the fish caught between the indicator and control locations.

Fish are caught by R. G. & E. biologists and analyzed by gamma spectroscopy after being held for periods of less than one week to keep the LLD value for the shorter half-life isotopes realistic. Detection limits could also be affected by small mass samples, (< 2000 grams), in some species.

Gamma isotopic concentrations (pci/kilogram wet) are listed in Tables 3-17A, and 3-17B.

3.6 Sediment Samples Samples of shoreline sediment are taken upstream (Russell Station) and downstream (OWD) of Ginna Station.

Results of the gamma isotopic analysis for sediment are included in Table 3-18, along with benthic sediment from Lake Ontario.

3.7 Vegetation Samples Crops are grown on the plant property in a location with a higher D/Q than the location of the maximally exposed individual, and samples of the produce are collected at harvest time for analysis. Control samples are purchased from farms greater than ten miles from the plant. (Gro-Moore Farm Market in Henrietta, New York). There was no indication in the samples of any measurable activity other than naturally occurring K-40 and Ra-226.

Gamma isotopic data is given in Table 3-19.

3.8 External PenetratinQ Radiation Thermoluminescent dosimeters, (TLD's), with a sensitivity of 5 millirem/quarter are placed as part of the environmental monitoring program. Thirty-nine TLD badges are currently placed in four rings around the plant. These rings range from less than 1000 feet to 15 miles and have been dispersed to give indications in each of the nine land based sectors around the plant should an excessive release occur from the plant.

Badges are changed and read after approximately 3 months exposure. One measurement was missing - in the fourth quarter, TLD #18 was lost due to weather.

TLD locations #7 and #13 are influenced by close proximity to radioactive equipment storage areas and will normally read slightly higher than other locations. For the year of 2003, on-site exposure ranged between 8.7 - 16.6 mrem/quarter, with an average exposure of 12.4 mrem/quarter and off-site ranged between 8.4 - 13.3 mrem/quarter with an average exposure of 11.0 mrem/quarter.

40 CFR 190 requires that the annual dose equivalent not exceed 25 millirems to the whole body of any member of the public. Using the annual average of control TLD stations as background and the highest site boundary TLD, #15, leads to 9.2 millirem direct radiation dose to the hypothetical maximally exposed member of the public at the site boundary.

Table 3-21 gives TLD readings for each quarter.

A trend chart with a comparison of data for each location for the years of 2002 and 2003 is included, Table 3-21. The data plotted is the average quarterly dose measured. TLD location #7 is elevated due to its proximity to radioactive equipment storage areas (47)

4.0 LAND USE CENSUS A land use census is performed each year to determine any major changes in the use of the land within 5 miles of the plant. There were no major changes in 2003. The land use remains mainly agricultural in nature. There were several new private home developments. Molino Farm ceased commercial operation early in 2002, leaving two dairy farms within 5 miles of the plant. There are no goats raised for human consumption of milk or meat within the five mile radius. Beef cattle are still raised on 3 farms within 5 miles of the plant as in past years.

An on-site garden is used for broad leaf vegetation and on-site crops are collected for indicator samples when available.

A copy of the Land Use Census that was completed in September 2003 is attached.

Detailed land use census data is available on file at Ginna Station.

5.0 EXTERNAL INFLUENCES During 2003, there were no external influences such as atmospheric weapons testing or accidents at other nuclear facilities which had an impact on the data.

6.0 QUALITY ASSURANCE 6.1 INTERLABORATORY BLIND SAMPLE COMPARISON A Laboratory's participation in an interlaboratory comparison program provides a means for verifying the measurement accuracy of radioactive material in environmental sample media with another laboratory. The ODCM requires participation in an interlaboratory comparison program that is approved by the NRC, if such a program exists. Until 1996 the United States Environmental Protection Agency (EPA), Office of Research and Development, National Exposure Research Laboratory, Las Vegas, Nevada, was the NRC approved program. Since the NRC has not approved a replacement for the EPA's program, Ginna Station has engaged the services of Analytics, Inc., Atlanta, Georgia for quality control blind spiked environmental sample media for interlaboratory comparison. Ginna Station submits blind spiked to our contract laboratory, James A. Fitzpatrick Environmental Laboratory (JAFEL), for analysis with field samples. JAFEL engages the services of Analytics and Environmental Measurements Laboratory (EML) for environmental sample media as blind sample spikes that are in addition to those submitted by Ginna Station.

An assessment of the blind spiked sample media for accuracy was performed, using the acceptance test generally referred to as the "NRC" method. This method is contained in NRC Procedure DVP-04.01 and was taken from the Criteria of Comparing Analytical Results (USNRC) and Bevington, P.R., Data Reduction and Error Analysis for the Physical Sciences, McGraw-Hill, New York, (1969). The Laboratory's accuracy is evaluation by comparison to a reference as follows:

Error Resolution = Reference Value Reference Uncertainty Comparison Ratio = Laboratorv Analysis Reference Value The reference value and uncertainty are Analytics values. Using Table 6.1A, the interval for the RATIO OF AGREEMENT is determined by the appropriate row under the ERROR RESOLUTION column. The RATIO OF AGREEMENT provides criteria for evaluating the comparison ratio as to being in agreement or disagreement. When the comparison ratio is found to be in agreement with the reference value a Laboratory's analysis does not have a statistically significant analysis error, either systematic or programmatic. If the comparison ratio is found to be in disagreement with the reference value the Laboratory's analysis has a statistically significant analysis error, which may be either systematic or programmatic.

<200 0.85 to 1.18 A 5% reference uncertainty was applied to the reference value. According to ANSI N42.23-1996, 5% is the maximum acceptable bias for a reference laboratory that prepares blind spiked samples. The ERROR RESOLUTION for all the Analytics' spiked samples was determined to fall between 15.6 and 50.5 which correlates to RATIO OF AGREEMENT OF 0.75 to 1.33.

Comparison ratios are displayed in Figures 6.1A, 6.1B, 6.1C and 6.1D along with a lower control limit (LCL) of 0.75 and an upper control limit (UCL) of 1.33.

6.2 ANALYTICS SAMPLE NON-CONFORMITIES For 2003, two nuclides fell outside ofthe LCL and UCL, based on JAFEL acceptance criteria. Co-58 (Figure 6.1E, QC-1) and Co-60 (Figure 6.1E, QC-2). In accordance with the Ginna Station acceptance criteria, both of these results were acceptable and required no further actions. JAFEL investigation of these two non-conformities is discussed below.

Co-58 Non-conformity A spiked mixed gamma in soil sample was received from Analytics, Inc. and was analyzed in accordance with standard laboratory procedures. The sample contained a total of nine radionuclides for analysis. Nine of the nine radionuclides present were quantified. Eight of the nine radionuclides were quantified within the acceptable range. The mean result for Co-58 was determined to be outside the QA Acceptance Criteria resulting in a sample nonconformity.

An evaluation of the Co-58 result was performed. The spectrum and peak search results were examined with no abnormalities identified. Co-58 decays by electron capture with a 70.9 day half-life and a gamma ray energy of 810 KeV with a yield of 99.5 %. No significant secondary gamma energies are produced in the Co-58 decay scheme. The average net count rates of the five analyses were very low and ranged from a high of 0.94 counts per minute to a low of 0.66 counts per minute.

The low activity in the sample resulted in high associated counting errors.

The combination of low sample activity, very low count rate, and high background level in the spectrum, resulted in an inaccurate sample result. The wide range of the associated counting errors demonstrates the low confidence level in the reported results. The nonconforming analytical results for this sample is not routine and does not indicate a programmatic deficiency in the analysis of Co-58 in soil samples or other environmental media. Confidence in the accurate analysis of Co-58 can be demonstrated by other Co-58 analytical results, both in the overall results for the 2003 QA program and historical Co-58 QA program results. The Co-58 results for the other Quality Assurance samples analyzed as part of the 2003 Interlaboratory Comparison Program were all acceptable and are summarized below:

1.01 Mean Ratio Ratio =

= 1.01 A review of historical QA data for the period of 2002 through 1999 was performed. There were no nonconformities related to the analysis of CO-58 during this period. In 2002, six QA samples were analyzed which contained Co-58. The mean ratio for these samples relative to the known value was 1.02. The 2003 nonconformity is considered to be an isolated instance. The low concentration of Co-58 present in the sample is considered to be the major contributor to the nonconformity. This low activity resulted in a very low count rate and a high net count rate to background ratio as indicated by the high associated counting error. The historical Co-58 results and the 2003 program result demonstrate that there is no systematic error or persistent bias present in the analysis of samples for Co-58 in soil or other environmental sample media. No corrective actions were implemented as a result of this nonconformity.

Co-60 Non-conformity A spiked mixed gamma in vegetation sample supplied by Analytics, Inc., was analyzed in accordance with standard laboratory procedures. The sample contained a total of nine radionuclides for analysis. Nine of the nine radionuclides present were quantified. Eight of the nine radionuclides were quantified within the acceptable range. The results for Co-60 were determined to be outside the QA Acceptance Criteria resulting a sample nonconformity.

An evaluation of the Co-60 result was performed. The spectrum and peak search results were examined with no abnormalities identified. The precise cause of the nonconformity could not be explicitly determined. The difference in the sample density and the density of vegetation geometry calibration source is considered to be significant contributing cause. The vegetation calibration source is constructed using 720 grams of homogeneous organic material in a one liter Marinelli beaker. The Analytics cross check sample contained 600 grams of the same material that was analyzed using the same counting geometry as the calibration source. In addition to the difference in sample density, the results were biased by settling of the sample in the Marinelli beaker, which because of the geometry, would place the material closer to the detector. With the material in the counting beaker being closer to the detector along with the overall difference in density, a positive bias would be introduced into the analysis. The presence of the high bias is confirmed by the results for the other radionuclides present in the sample. With the exception of Cr-5 1, the results for the other seven radionuclides resulted in high ratios (bias) relative to the known value and ranged from 5% to 22% higher when compared to the reference results.

The nonconforming analytical results for this sample media is not routine and does not indicated a programmatic deficiency in the analysis of Co-60 in vegetation samples or other environmental media. Confidence in the accurate analysis of Co-60 can be demonstrated by other Co-60 analytical results, both in the sample results for the 2003 QA program and historical CO-60 QA results. The Co-60 results for the other Quality Assurance samples analyzed as part of the 2003 Interlaboratory Comparison Program were all acceptable and are summarized below:

There were no nonconformities related to the analysis of Co-60 during this period. In 2002, eight QA samples were analyzed which contained Co-60. The mean ratio for these samples relative to the known value was 0.99. The 2003 nonconformity is considered to be an isolated instance. The lower sample volume/density produced a high bias in the analytical results which is considered to be the major cause of the nonconformity. The historical Co-60 results and the 2003 program result demonstrated that there is no systematic error or persistent bias present in the analysis of samples for Co-60 in vegetation or other environmental sample media. No corrective actions were implemented as a result of this nonconformity.

In 2003, Ginna Station implemented field spiked environmental TLDs byirradiatingTLDs with aCs-137 source to aknown dose. The spiked TLDs were placed in the field and processed with each quarter's environmental TLDs. The reported dose was background corrected, using the average of the field control TLDs.

The reported dose and delivered dose are used to calculate a performance quotient ((reported -

delivered)/delivered) for each TLD within the set of spiked TLDs. The performance bias is the average of the performance quotients. The standard deviation of bias is the standard deviation of the performance quotients. For the set of spiked TLDs a performance criteria is calculated by adding the performance bias and standard deviation of the bias. The performance criteria limit was established to be 0.20. Spike performance criteria of less than 0.20 validate the TLD processing at Ginna Station. All blind TLD performance criteria for year 2003 were less than 0.20. Figure 6.2A displays the spike TLD performance criteria.

6.4 AUDIT OF CONTRACT LABORATORY Ginna Station QualityAssurance personnel did not conduct an audit ofthe ODCM and REMP during 2003. In addition, there were no surveillances done at JAFEL in 2003. Surveillance is required every three years and one was done in 2001 in the following six areas: Control of M&TE, Control of Records/Documents, Control/Adequacy of Sampling and Analysis, Handling, Shipping and Storage of Samples, Qualification/Training of Personnel, and Quality Programs Controls. Surveillance Report SQUA-2001-0002-AZP indicates the laboratory has functioned in an acceptable manner and was rated satisfactory with respect to all six criteria.

7.0 DEVIATIONS FROM SCHEDULE Four items reportable in the Annual Environmental Radiological Operating Report under procedure CHA-RETS-VARIATION were reported as follows:

1. Environmental Air Sample Station (ES) # 2 lost power in the ice storm of 4/5/03.

Power could not be restored on 4/9/03. Trouble card issued for repair. No sample for the week of 4/8/03 - 4/14/03.

2. ES #2, 3, 4, 5, 6, 7,11,12 lost power during the ice storm of 4/5/03, but had sufficient sample volume to report gross beta.

3. ES #9 found off on 6/24/03. No sample for week of 6/16/03 - 6123/03. Repaired by next sample period.

4. ES #13 found 8/26/03 with missing paper filter due to pump malfunction. No sample for week of 8/18/03 - 8/25/03. Repaired by next sample period.

In addition to these deviations, two environmental air sampler flow meters failed as found criteria at annual preventive maintenance. Although the failures appeared to have occurred during the test procedures, average air radioactivity and conclusions derived from air radioactivity applied the as found flow rate to the entire sample periods.
