, 1. RADIOLOGICAL MONITORING 1.1 Introduction l The objectives of the Radiological Environmental Monitoring Pmgram are to ascertain the levels of radiation and concentrations of radioactivity in the environment which are due to plant operations and to evaluate the impact to the environment from these radiological levels. Assurance is provided in achieving these objectives by following the program's requirements as described in Section 3.2 of the Environmental Technical Specifications (ETS). f Provided herein are the program's results for calendar year 1984 which include -
an assessment of the radiological impact upon the environment, as well as reports on various related activities. A summary, interpretation and evaluation of the analytical results obtained from the samples utilized for the environmental monitoring of discharges of radioactive materials to the atmosphere and river are provided, as appropriate, in Sections 1.2 and 1.3 respectively. The data on samples recpired by the ETS are tabulated by station or group of stations. As practical, each tabulation consists of: the maximum, minimum and average values of the radiological level; the number of samples (n); and the standard l deviation (s). Nominally, summaries are provided for the control and indicator stations on an annual basis; they may also be provided for other periods of exposure as feasible. The calculated minimum detectable difference (MDD) at the 9915 confidence level between these two groups is provided for comparison with the difference in their average values, Li-Lc. Deviations are permitted from the sampling schedule required by Table 3.2-1 of the ETS if specimens are unobtainable due to hazardous conditions, seasonable unavailability, malfunction of automatic sampling equipment or other legitimate reasons. Any deviations from the required sampling schedule are included in the discussions for each particular type sample. The sampling of groundwater to monitor discharges to the ground began during , the preoperational phase of the radiological environmental monitoring ' prograr . Although high tritium levels in groundwater samples have been found near the main plant buildings, these have little impact offsite. There have been no ETS requireenents for the sampling of groundwater since 1978, at the time when HPF-2 began operation. At a meeting on December 19, 1983 with EC Region II, it was agreed that the reporting in the annual environmental surveillance report of onsite radiological levels in groundwater was . inappropriate and that such reporting in the annual report was to stop after the report for calendar year 1983. Groundwater sampling continues but reports are made to the MC by other means. In Section 1.4, the results of the EPA Crosscheck Program are provided. In Section 1.5, the chief conclusions are presented. O l-1
1.2 Discharges To The Atmosphere The media or pathways samplea to monitor discharges to the atmosphere consisted of: aizborne aust, airborne iodine, external radiation, milk and grass. Aizborne dust and iodine were collected at air monitoring stations. In accordance with the ETS, thermoluminescent dosimeters (TLDs) for measuring external radiation were placed at each of the air stations and at three other locations as shown below. Starting with the 1st quarter of 1980, additional
. TLDs were placeo in the site environs to conform with Revision 1 of the Technical Position of the Radiation Assessment Branch of the MtC, dated November 1979. The locations of these new TLDs are described in Section 1.2.3. The locations of the milk sampling stations are pzovided in Section 1.2.4. Grass samples were collected from plots maintained at Air Stations 5, 17 and 21. The sector location and distance as zeckoned from the main stack to each of the air stations and to each of the TLD stations required by the ETS are as follows:

All required laboratory analyses of the samples collected to monitor discharges to the atmosphere are contracted to Teledyne Isotopes, Inc. of Westwood, New Jersey except for: the gross beta counting of airborne particulates which is perforneo by the plant; the zeaoing of the TLDs which is done by Teledyne Isotopes Midwest Laboratory at Northbrook, Illinois; and the gamma scan of grass which is provided by the Center for Applied Isotope Studies at the imiversity of Georgia in Athens, Georgia. 1.2.1 Airborne Dust
' The annual summary of the gross beta activities for the airborne dust samples which were collected weekly is presented in Table 1.2-1 for the locations required by the ETS. The average activity for the indicator stations is seen to be slightly less than that for the control stations; the absolute value of the difference between these two values is less than the K)O.

i i i The average gross beta activity for all stations during 1984 was 27 fCi/m3; it averaged 31 and 33 fC1/m3 during 1983 and 1982 respectively. Going back to 1976 and for several years afterwards, it was 4 to 8 times greater than that for 1984. Those high values were shown to be the result of fallout from ! che numerous nuclear weapons tests conducted on mainland China from 1976 through 1980. In the proposed Radiological Effluent Technical Specifications (RETS) which
- were submitted to the PRC on August 1,1984 and which are expected to be implemented during 1985, Station 15 which is located in the WNW sector about 0.4 miles inside the site boundary is replaced with Station 150 which is 4 located in the PNW sector at 1.6 miles or about 0.15 miles outside the site boundary. Operations persomel failed to take a sample at Station 15 for the
- first week of 1984 thinking the phase out was to start at the begiming of 4 1984. The gross beta activities at Station 150 ranged from 13 to 53 fC1/m3 i during the year with 30 fC1/m3 as an average. These values are within the
- range of those found at the other air stations.
Due to mechanical failures, valid data was unavailable on one occasion at Stations 9 and 21, on two occasions at Station 17 and on three occasions at Station 15. Of the seven occasions, six were due to broken filters and one was due to a power failure to the pump. Most of the broken filters were oue to acts of bees or other insects; a better screening mechanism on the air i intake is planned to alleviate this problem. The amuel summary of activities for specific radionuclides detected in ouarterly composites of airborne dust filters by gamma spectral analyses are , provided in Table 1,2-2. The naturally occurring radionuclides Be-7 and K-40 l were detected at levels and frequencies of occurrence typical of those found j in previous years. At Station 150, like the other air stations, Be-7 was i found during each quarter and averaging 57.6 fCi/mI. with activities No other ranging were raolonuclides from detected 49.1 to 62.5 fCi/m3 during the first three quarters of the year. During the 4th Quarter, a total of five different manmade Isolonuclides were detected at five of the air stations with activities in units of fC1/m3 as follows: Station Mn-54 Co-60 2n-65 Zr-95 Nb-95 1 1.06 6.46 7.24 9 0.45 15 1.73 2.23 0.82 1.50 17 0.79 150 1.07 ! RL 7730 1720 12100 5580 20000 The Reporting Level (RL) is also listed for each of these radionuclides to emphasize how miniscule the detected levels are. The RL for a given I radionuclide is the lowest concentration which would render an amual design objective dose of Appendix I to 10CFR50 to some individual when so exposed for a period of one ear. The LLDs usually achieved for these radionuclides are ( around 0.5 fCi/m . 1-4

i i j These manmade radionuclides have all been detected previously. All except ! Zn-65 had been detected on numerous occasions during the times of the Chinese nuclear weapons tests from the mid-seventies through the early eighties. ! ! During these times the readings ranged from those detected in 1984 to about 20 i ! times greater. The radionuclide Zn-65 had been detecteo only once previously
- during 1982 at an indicator station with a zeading an order of magnitude higher than that found in 1984.
1 . Assuming that the reported values of these manmace radionuclides represent the actual average conditions at the sampling locations during the ALh Qua rter, the highest dose an individual would receive by breathing these sizborne i particulates at these locations during the entire quarter is 0.017 mrem. This is well below the quarterly limit of 7.5 mrem specified by Appendix I to 10 i CFR 50. This maximum dose would be Ieceived by a teenager at Station 1 which j is 11.3 miles away. i . Each of these radionuclides except Zn-65 is found in the gaseous releases from ) Plant Hatch. Based on the meterological conditions and the releases during the 4th quarter, the average ai2boIne concentrations were calculated for j each radionuclide at the points they were measureo. Most of the measured values were about three orders of magnitude gItater than the calculated values i but a few were less than an order of magnitude greater. Contamination fIom j handling within the plant is suspected as these radionuclides are zegularly j present in the liquid radweste. Plans are afoot to have all of the laboratory 4 analyses on the airbome dust filters cone off site; this would preclude the j necessity of bringing the filters inside the plant area. !O 1 2.2 Airborne roeine ! The charcoal cartridges used for adsorbing iodine from the atmosphere were i collected weekly and analyzed for I-131 by Ge(Li) spectroscopy. I-131 was not i detected in any of the samples curing 1984. The maximum allowed LLD is 70 fC1/m3; the LLDs achieved during 1984 never exceeded 50 fCiAn3 The RL is 900 fC1/m3 ! 1.2.3 Thermoluminescent Dosimeters The nominal location of each of the TLDs by sector and by distance from the
! main stack in miles is provideo in Table 1.2-3. Two badges are placed at each j station; each badge contains five LiF chips. At the beginning of 1980, an j attempt was made to establish two TLD stations in each sector (in accordance with Revision 1 to the Technical Position of the Radiological Assessment Branch of the l@C, dated November 1979), one near the site boundazy and the other at a distance of about four or five miles. Suitable locations were not found in the East Sector. In addition to the locations for these two rings of TLD stations, the table provides for the locations of the control stations and
, the stations of special interest. I i i

I A flood plane is. located at the Isdii of these two rings in the East Sector precluding easy access to such locale for several months during the year. Thus TLDs were not placed in the East Sector. Subseouently, it was decloed to , complete the two rings even if the racii in the East Sector were a few miles greater than in the other sectors. At the beginnin TLDs were addea in the East Sector at Isdil of 3.6 ana 7.2 miles;g of 1984,these locations have been designated as Stations 105 ano 205, respectively. The annual summary of the on-station doses acQuizea by the TLDs which are Ieoulzec by the ETS is presentec in Table 1.2-4. There is no disceInable difference between the average values at the incicator anc control stations. The annual summary of the on-station doses acouizeo at the site boundary and at 4-5 miles is presentea in Table 1.2-5. Again, there is no discernable cifference between the average values at the site boundazy anc the 4-5 mile ring. The on-station Quarterly cases acquirea by the TLDs placea at Station 31 (Toombs Central School) rangeo from 11.9 to 12.8 mrem with 12.4 mIem as an average. The results for the 3rd ano 4th Quarters were considerea to be erroneous and therefore not included with the data discussed above. In the process of being brought into the protected area, the package of TLDs had passeo through the Iecently installed x-ray machine usea by the Security Department for surveillance purposes. The packages were labeled "Do Not X-ray" in light pink but apparently these labels were not noticed. The TLDs used for environmental monitoring are no longer brought into the protected area. The TLDs passing through the x-ray machine received nonunifoIm exposures because of the variable shielding affoIdeo to each baoge in the package and the orientation of the individual TLD bacges to the x-ray beam. The two bacges in the package which accompany the shipment to oetermine the in transit exposures acouired about 5 and 3 times their usual dose in the 3Id ana 4th Quarte rs, respectively after subtzsc' ting this "in transit" component, the Iesultant readings wer;e low for those baoges which obviously acouizea much less dose from the x-rays. The reaoings for the two TLD badges placed at the same location in the fielo usually differ by less than 0.5 mzem. In the 3rd ouarter, 80% of the reacings foI TLD pairs differea by more than 2 mIem, 20% by more than 4 mIem, the maximum difference was 10.5 mzem. In the 4th Quarter, about 43% diffezea by more than 2 mrem and about 14% by more than 4 mIem, the maximum difference was 7.6 mIem. TLDs aIe fIecuently lost due ta theft and aIe fIeouently damagea by vanoalism. At monthly intervals the TLD stations are checkeo for missing or damaged badges; replacements are provided as neeoed. Both badges were missing: at Station 29 at the end of the first ouarter, ano at Stations 25 and 205 at the eno of the second Quarter; this accounts for the lower value of n at these locations in Table 1.2-5. A total of 7 badges from 4 different stations were founa to be missing curing the first half of the year. To diminish the frecuency of missing or damage 0 badges, TLDs are placeo in less conspicuous places whereveI this is practical. O v I-8

1.2.4 Milk O Milk samples are collected biweekly as available at three stations. Gamma isotopic and I-131 analyses are performed on each sample. The locations of , the milk sampling stations and the number of samples analyzed were as follows: ' Station Sector Distance 9 State Prison EE 10.8 miles 26 Johnson Brothers SW 9.1 miles 26 Williamsons t#E 3.2 miles 19 For two successive years the pregnancy of Williamsons' cow in the latter part of the year has pIecluded the availability of milk samples at that station for a few months. For that zeason, no samples were available for the first i collection date of the year and also during November and December. On one occasion in mid June, no sample ras available due to the absence of the family. The State PIison is the control station and Williamsons is the indicator station. Johnson Brothers Dairy is a bit too far away to be considered as an indicator station; however, it is the closest location in the sector into which the wino blows most frequently. r There has been no positive indications of I-131 in any of the milk samples for four years. Pzevious levels rangeo from 0.095 to 88 pCi/1. All significant readings were generally attributed to the weapons tests. The LLD required by the ETS is 0.8 pCi/1; the RL is 3 pCi/1. O As usual, the gamma scans showed naturally occurring K-40 present in each l sample at levels which varied between 749 and 1730 pCi/1. These levels are l about the same as those found in previous years. j The gama scans also showeo positive indications of the presence of the fission product Cs 137 in about a quarter of the samples collected. The levels were found to be about the same as those found previously. The results in pCi/l for each station are summarized as follows: Station nb Maximum Minimum Average s Prison 2/26 12.8 7.6 10.2 3.7 Johnson Brothers 12/26 13.8 7.3 9.9 2.2 Willit.msons 3/19 10.4 8.0 9.6 1.3 The ratio, n/n ,o is the number of positive results to the number of analyses performed. As usual, more positive results were found at Johnson Brothers. The maximum LLD allowed by the ETS is 15 pC1/1; in practice, however, a LLD of 7 pC1/1 is usually achieved; the RL is 70 pCi/1. The positive levels found during the past six years ranged from 6.7 to 57.1 pCi/l with the average values for the stations ranging from 7.2 to 20.9 pCi/1. During preoperations, Cs 137 was measured in milk by a chemical separation technique; the levels ranged fzom 2 to 60 pCi/l with an average value of 19.3 pCi/1. All of these positive indications of Cs 137 in milk, those during preoperations, as well as those during operations, are attributed to the weapons tests. 1-11
l The ETS require that a survey be conducted amually to determine the location O of all milk animals within 3 miles of the plant in each of the 16 azimuthal sectoIs. For any of the 16 sectors in which a milk animal is not found within , 3 miles, the survey is expanded to locate the nearest allk animal within 5 ' miles in that sector. A milk animal is a cow or goat which is producing milk for human consumption. On May 21, the milk animal survey was conducted. The only milk animal found was the cow at Williamsons which is presently being sampled. 1.2.5 Grass Ganna isotopic analyses were performed on each of the grass samples collected monthly from the three sampling stations. Positive indication for several radionuclides were determined. These have been separated into four groups as follows: (1) Be-7 and K-40; (2) Cs-137; (3) Pb-214 and Bi-214; and (4) T1-208, Fb-212, and Ac-228 The only manmade zadionuclide is Cs-137 in the second group. Each of the radionuclides detected except for Be-7 had been found in soil samples taken at each of these plots several years ago. An annual sunnary of the activities of these radionuclides is provided in Table 1.2-6. It is seen that there are no' discernable differences between the average values of the indicator stations and the control station. Except for K-40, the control station had higher O average values. As usual, Be-7 and K-40 were detected in every sample. The levels are on the same order of magnitude as those found previously. Overall the levels for Cs 137 were found to be about 50K higher than those found during 1983. As usual, the control station values were considerably higher than those for the indicator stations. In June and July, levels of 1380 and 1300 pCi/kg wet were detected at Station 5, the control station; these levels are about 4 times higher than any other reading at that location during the year. The RL is 2000 pCi/kg wet. Station 5, which is 10 miles from the plant, has a history of high Cs-137 zeadings. The maximum zeadings obtained in each of the years from 1978 through 1981 weze 1500,1680,2330 and 1740 pCi/kg wet, respectively. Each of these readings except that for 1981 occurred at Station 5; the high zeading for 1981 occurred at Station 17. Each of the zadionuclides in the third and fourth groups is a primordial nuclide. The radionuclides in the thizd group are from the Uranium Series. Those in the fourth group are from the Thorium Series. The levels are typical of those found previously. O l-12

J 1 j The ETS require a LLD of not greater than 25 pC1/kg wet for I-131. This limit l was exceeded on four occasions as follows: 1 Station 5 17 21 j my M . June 44 September 32 26 l 1 Iodine has a strong affinity for water; the moisture content in these samples l was low due to vezy dry weatheI. The wet to dry ratio for these samples j averaged 1.94; it is typically thre.e times higher at other times. l Largely due to colder than normal weather in the winter, to the hot sumer ! weather and to the dry conditions late in the year, less than ordinary success l was experienced in obtaining adequate grass samples. No samples at all were obtained in February, November and Decenber. In January, no sample was obtained at Station 21; in June through September, none was obtained at Station 17. In the proposed RETS, Station 17 is to be zeplaced. The new 4 location has been cleared and seeded; initial grass production inoicate's some improvement. 1.3 Discharges to the Riv.er The ETS zequize the sampling of water, clams and sediment from River Stations 170 and 172 which are about a mile upstream and about 2 miles downstzeam, O zespectively. The upstream station serves as the control station and the downstream station serves as the indicator station. The ETS also zequire the sampling of American shad from the area of the discharge structure. The ETS recuize a game spectral analysis of each sample. This analysis is performed on only the edible portion of the fish and clam samples. A tritium analysis is also required on quarterly composites of river water for each station. All of these analyses aze performed by Teledyne Isotopes, Incorporated of Westwood, New Jersey. 1.3.1 River Water River water is collected using automatic sampling machines; small samples are collected at intervals which are on the order of an hour. Water thus collected is pickea up monthly; quarterly composites are composed of the monthly collections. There was one positive result for the entire year on the gamma scans of the monthly collections. The naturally occurring K-40 was detected at Station 170 in October; the reading was 63.3 pCi/1; the LLD generally achieveo Isnges from 50 to 100 pCi/1. Only scant positive results have been obtained in the past with this analysis. The only manmade radionuclide ever detected was Oe-141; this occurred only once at an indicator station in the 4th quarter of 1975. O 1-14
The positive results in units of pCi/1 for the tritium analysis of the Quarterly composites are summarized as follows for the control and indicator stations, respectively. n_ Max Min v A_vg s_ % MDD 3 500 210 327 153 - 3 470 370 437 58 110 262 Although the indicator station had higher average values than the control station, the difference between these values was less than the MDD; hence, there is no discernable difference between the readings at these two stations. These average readings are slightly higher than usually found. The previous maximum annual average reading was 358 pCi/l at Station 172 for 1980. In the 3Id quarter of that year, a zeading of 640 pCi/l was found at Station 172; this is the highest individual zeading yet cetecteo. In the 4th quarter of 1984 the readings at both stations were less than 100 pCi/1. The monthly samples for April were inadvertently analyzeo for tritium; levels of 270 and 340 pCi/1 were found for Stations 170 and 172, respectively. In accordance with the ETS, a survey was conducted downstream of the plant on September 1718 to determine if water fIom the Altamaha River was being used for drinking purposes. As in all previous surveys, no intakes for drinking water were observed. If river water should become used for drinking, the ETS require sampling and analyses of the drinking water. 1.3.2 Clams The ETS require a semiannual sampling of asiatic clams from the two river stations; if clams become unavailable, samples of a commercially or zecreationally important species of fish will be collected. Since sufficient Quantities of clams were not available on May 30 and November 11, two species of fish were collected at each of the two river stations. To provide support for the site specific assumptions and parameters to be used in calculating doses due to liquid effluent releases for the proposed Radiological Effluent Technical Specifications, fuIther fish collections were mace between 3J1y 30 and August 1. In addition to collections at Stations 170 and 172, collections were made over a stzetch of the river from the discharge structure to about a half mile downstzeam; this location is designated as Station 171. O l-15
The species collected at each station for each time period during the year L were as follows: Time Period Station 170 Station 171 Station 172 5/30 D, F D, F 7/30 - 8/l A,D,E,F,G,H C,D,F all 11/14 A, D A, D Specie A American Eel Specie B Bluegill Sunfish Specie C Channel Catfish Specie D Largemouth Bass Sp?cie E Mullet Specie F Re@Itast Sunfish Specie G Redear Sunfish Specie H White Crappie During the perico JJ1y 30 through August 1, two largemouth bass samples were collected at each station except Station 172 where three such samples were collected. Among the 29 samples analyzed, three olfferent radionuclides were detected. The naturally occurring K-40 was found in each sample at level:. ranging from 1.49 to 4.57 pCi/g wet. The readings were typical of those found previcusly. N The fission product Cs 134 was detected in two of the samples. A level of 0.0358 pCi/g wet was found in a largemouth bass collected on July 31 at Station 171 which is just downstream of the discharge structure; a level of 0.0263 pCi/g wet was found in a mullet collected on August 1 at Station 170 which is a mile upstream of the discharge structure. The LLD values measured in the samples were found to Iange from 0.01 to 0.05 pCi/g wet. The ETS require that the LLD not be greater than 0.13 pCi/g wet; the RL is 1.0 pCi/g wet. The radionuclioe Cs-134 had been detectea previously on only one occasion; in November 1983, the two samples collected at Station 172 had readings 'of 0.0547 and 0.149 pCi/g wet; the average value of these 1983 Ieadings is about three times greater than that detected this year. The fission product Cs 137 was detected in all but four of the samples. For the positive results, the levels in units of pCi/g wet are summarized as follows: - Station g Max Min A3 s M-k HD0 170 11/11 0.088 0.037 0.053 0.015 171 3/4 0.135 0.041 0.083 0.048 .030 .253 172 11/14 0.144 0.037 0.064 0.030 .031 .029 l 16
These readings are well within the range of those found in past years. The O ETS require that the LLD not be greater than 0.13 pCi/g wet; the RL is 2.0 pC1/g wet. The average value at each of the downstream stations is greater than that for the upstream station. It should be noted that this difference between Station 172 and Station 170 is discernable. Using only the positive results in looking for discernable differences between sample locations may be too conservative and unrealistic. By dropping the aless than" inequality for the nonpositive results and incluaing them in the summary, a different picture emerges. At station 171, a sample with a value of 0.03 pC1/g wet is added; at Station 172, two samples with values of 0.05 pCi/g wet and one with a value of 0.03 pCi/g wet are aaded. The above summary becomes: Station n/n o Max Min v Avg s_ M-k MD0 170 11/11 0.088 0.037 0.053 0.015 171 4/4 0.135 0.030 0.070 0.047 0.017 0.129 172 14/14 0.144 0.030 0.075 0.032 0.022 0.029 The difference between the average values at Station 172 and Station 170 is no j longer discernable. Using all the data may provioe more realistic results. The largemouth bass sample collected at 5 cation 171 on N1y 31 had the highest Cs-134 level (0.0358 pCi/g wet) and nearly the highest Cs-137 level (0.135 pCi/g wet). A greater dose would be zeceived from eating fish with these concentrations than that found in any other fish sample collected during the year. The dose to an individual from consuming fish for a year with these concentrations woulo be 0.43 miem to the livez of a teenager; 0.11 mzem of this dose is due to the Cs-134 and 0.32 mrem is due to the Cs437. This calculated dose is well below the design objective of 10 mzem per year to any organ for liquid releases as specifico by Appendix I to 10 CFR 50. Assumed values for the parameters used in this calculation were tanken from Revision 1 of Regulatory Guide 1.109, October 1977. The higher levels of Cs 134 and Cs-137 found in fish collected from the downstream locations may at least partially be attributed to plant releases. The presence of Cs-137 hao largely been attributed to the weapons tests. The appearance of Cs 134 beginning last year is a few years subsequent to the
- weapons tests.
Both Cs 134 anc Cs 137 are among the radionuclides comprising the liould releases. A cursory look at the release data over the past few years indicates the annual increase to be nearly linear. The yearly releases in units of Curies were as follows: Year Cs 134 Cs 137 l 1982 0.111 0.165 1983 0.225 0.357 1984 0.337 0.480 !O : 1-17 l -- _ _ _ _ _ . . - _ ____
l.3.3 American Shad Because of its commercial importance, the ETS requite that American shad be collected annually during the spring spawning period. The collection was made on March 13. Naturally occurring K-40 was the only radionuclide detected in this single sample. The level was 3.39 pC1/g wet which is about the same as that found previously. Only K-40 has been found in previous samples of American shad. This sample has been collected for seven years. 1.3.4 Sediment The annual collection of sediment took place on May 30. Additional sediment collections were made on July 30 not only at Stations 170 and 172, but also at a location about a quarter mile below the discharge structure desigasted as Station 171. The activities in units of pCi/g dry of the radionuclides detected from the gamma scans of these samples are pmsented below: Radionuclide Date Station 170 Station 171 Station 172 Be-7 5/30 1.25 1.35 7/30 0.30 0.20 0.30 K-40 5/30 7.93 9.72 7/30 5.78 4.18 10.70 Cs 134 5/30 0.05 0.22 7/30 0.03 0.02 0.15 Cs 137 5/30 0.49 0.73 7/30 0.03 0.02 0.27 Ra-226 5/30 3.23 3.06 4 7/30 0.77 0.40 3.03 Th-228 5/30 1.68 1.87 7/30 1.18 0.14 1.93 Except for Cs 134, the levels and frequencies of occurrence for these radionuclides are typical of those found pIeviously. Each of these radionuclides is naturally occurring except for Cs-134 and Cs 137. It is noted that the positive levels for Cs-137 at the indicator station are about twice the reading for the control station and that Cs-134 was detected
- only at the indicator station. These might be at least partially accounted for by the higher liquid effluent releases of Cs-134 and Cs 137. Cs 134 had been detected twice previously: in 1981 at the indicator station at a level of 0.28 pCi/g dry; and during preoperations at the control station at a level of 0.04 pCi/g dzy. Each of these occasions occurzed during a period when the inpact of the nuclear weapons tests was apparent through a number of different radionuclides in a number of sample media. The ETS reouize the LLD for each of these cesium isotopes not be greater than 0.15 pCi/g dry.

I 1.4 Crosscheck Program Laboratories perfoming the analyses required by the radiological environmental monitoring program as oelineated in Table 3 .- 21 of the ETS participate in EPA's Environmental Radioactivity Laboratory Intercomparison Studies (Crosscheck) Program conducted by the Environmental Monitoring and Support Laboratory in Las Vegas, Nevada or in an equivalent program. Not all of the sample media / analyses combinations listed in the ETS are covered by the Czosscheck Program. Reported hezein aze the zesults of zelevant participation in the Crosscheck Program by these laboratories. Relevant participation is considezed to consist of those analyses for sample media covered by the EPA Crosscheck Program which are the same as those zequired by the ETS. HPF conducted the gross beta analysis of air filters; all other zelevant media / analysis combinations were conducted by Teledyne. Because of the time lag involved in obtaining results from the EPA and the subsequent zeporting of these results by the contract laboratories, not all of the 1984 zesults were available. The results zeported herein also include the 1983 results which
- were not available last year.
, Any results of determinations in the Crosscheck Program for which disagreement can be established using the IEC's " Criteria for Comparing Analytical ~ Measurements" as described in Attachment 1, were investigated to detemine the cause of the disagreement. Corrective actions were taken as warranted. The results of any such investigations and corrective actions are zeported in this section. since all of the results reported herein are presented in the same tabular O format, an explanation of the column headings is provided. "Date" means the collection date given by the EPA. "Known" refers to the EPA known value + one standard deviation, s. " Result" is the average value measured by'~ the laboratory + experimental s. " Resolution" is detemined by dividing the known ! value by ifs s value. " Ratio" equals the "zesult" (value detemined by the laboratory) divided by the "known" (value determined by EPA). An explanation i is provided in the text for any of the comparisons showing " Disagreement". It j should be noted that whenever the EPA known value is zero or the laboratory detezmined result is a "less than" value, a comparison by the PRC criteria cannot be made since the zatio cannot be determined. The results of the gross beta and Cs-137 analyses of air filters are given in Table 1.51. Listed in Table 1.5-2 are the zesults of the I-131 and gasma analyses of milk samples. Table 1.5-3 presents the results of the genue and tritium analyses of water. No comparisons show disagreement except for one of the gross beta analyses on the air filters. The results for the gross beta analyses on the air filters 'for March 23, 1984 showed disagreement; the November 25, 1983 results showed possible agreement. An examination of the data for the Novesber 25 sample revealed an arithmetic error. The corzucted result is 43.8 which zenders a ratio of 0.88 which is agreeable. Correcting an assumed similar error on the March 23 sample provides a result of 34.8 and a . ratio of 0.68 which is agreeable. The
- procedure for detemining the activities of the EPA samples is being clarified to prevent an error of this sort in the future.

ATTACtNENT 1 Criteria for Comparing Analytical Measurements This attachment provides criteria for comparing results of capability tests and verification measurements. The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this program. In these criteria, the judgment limits are variable in relation to the conparison of the Reference Laboratory's value to its associated one sigma uncertainty. As this comparison, referred to as " Resolution" increases, the acceptability of a licensee's measurement should be more selective. Conversely, poorer agreement shoulo be considered acceptable as the resolution decreases. The values in the ratio criteria may be rounded to fewer significant figures to maintain statistical consistency with the number of significant figures zeported by the Reference Laboratory, unless such rounding will result in a narrowed category of acceptance. The acceptance category reported will be the narrowest into which the ratio fits for the resolution being used.

- l. summary, an interpzetation and an evaluation (where warranted) of the results of the laboratory analyses for each type sample collected have been presented.
' No measurable Indiological impact upon the environment as a consequence of discharges to the atmosphere was established.
- A discemable difference between the positive levels of Cs-137 found in fish sanples collected at the indicator station and at the control station was noted. The impact of these higher downstream levels was miniscule - less than 4% of the RL.

s HNP ANNUAL REP 01E O 2. METEOROLOGICAL MONITORING 2.1 Introduction The year 1984 was the first full year at Plant Hatch using the meteorological data from the new 100m meteorological tower. 2.2 1984 Data 2.2.1 Data Recovery Data recovery for the year was better than 90% for all parameters and composites of pertinent parameters. There were some occasional periods of bad data (nonc longer than 4-5 days) caused by instrument malfunctions and strip chart problems (Table 2.2-1). 2.2.2 Wind Roses The wind speeds and direction data presented by the seasonal and annual ! wind roses (Figure 2.2-1 through 2.2-6) compares well with previous years. We are now working with higher levels than on the old tower but that should have little.effect on the wind directions. The annual wind roses from all three levels agree quite well, particularly the 60s and 100m. There are some minor differences between the two upper levels and O the 10m level in the south to west sectors. This appears to occur mostly during light winds in the summer months when the upper levels tend to show southwest to west vinds and the 10m level south to southwest winds. The wind roses correspond well to previous years within normal climatic variations. The major difference between the 1983 and 1984 wind roses being the shift from a predominant northwest wind to a predominant southwest wind in 1984. This is most likely the effects of year-to-year variations. 2.2.3 Temperature Data The ambient and dew point temperatures (Figures 2.2-7 and 2.2-8) reflect the general climatic conditions in the southeast U.S. during 1984. The Winter and Spring months compare well with previous years and climatic normals. The Sunumer months were cooler than normal with average high temperatures in the middle 80's instead of near 90 as in most previous i years. The dew point also averaged about 5 degrees below Summer normals. In the Fall and early Winter, however, conditions reversed with temperatures t warmer than normal during September, October and December. In fact, comparing this December, one of the warmest on record, with December 1983, a very cold one, shows average temperatures of 56 degrees versus 46 degrees a change of about 10 degrees in one year. 4 3 O 2-1 {
2.2.4 Joint Frequency Tables ( The joint frequency tables (Tables 2.2-2 through 2.2-4) show some differences that reflect the changes in sensor heights on the new tower. Under normal circumstances, the area around meteorological towers is usually a combination of patchy grass and weeds. This type of sparsely covered surface allows for greater surface heating. As one moves up in the atmosphere the rate of temperature change decreases with height in the lower 1000m. In the case of the old meteorological tower, the delta temperature was taken between 150 f t and 33 ft or a distance of 117 f t. At the present time, the closest comparative level would be between 197 ft and 33 ft or 164 ft. This additional distance means less A stability during the daylight hours due to the increased height the stability is being configured over. The following table shows the latest 5 year stability classifications.

In accordance with Section 5.7.1 of the HNP-ETS, Units 1 and 2, the HNP Annual Environmental Surveillance Report will include a summary of all instances of Environmental Technical Specifications (ETS) noncom-pliances and corrective action taken, changes in federal and state permits and certificates, changes in the Environmental Program Descrip-tion Document (EPDD), changes in station design or operation which could involve an environmental impact, changes made to the ETS, and copies of all reports regarding station discharges made in accordance with NPDES Permit No. GA-0004120. 3.2 Discussion The Georgia Department of Natural Resources Environmental Protection Division (EPD) issued three letters stating violations of Plant Hatch's NPDES permit No. 0004120 and its Industrial and Hazardous Waste Management Program I.D. No. GA D000612564. Copies of the letters can be found in Appendix A. The following is a summary of the violations. In a letter dated May 18, 1984, the EPD issued a Notice of Violation of the NPDES permit for exceeding effluent limitations for pH from the liquid radwaste system discharge and for not Os meeting pH monitoring reporting requirements of the neutralization tank and pressure filter backwash. A letter stating a violation of the NPDES permit was issued January 4, 1985, by the EPD for receiving the Operation Monitoring Reports at least a month late every reporting period.

Dear Mr. Byerley:
In accordance with State and Federal law, the Environmental Protection Division has issued a National Pollutant Discharge Elimination System (NPDES) permit for your water pollution control facilities. We suggest you review
~
this permit in detail . , O Review of your Operation Monitoring Reports for the last two quarters of 1983 and the first quarter of 1984 indicated that your facility exceeded permit effluent limitations for pH from the Liquid Radwaste System discharge. While none of these violations individually are serious incidents, the frequency indicates that there is a problem in properly neutralizing the water from the Radwaste system. Please be advised that your company must take any necessary measures to comply with effluent limitations of your NPDES permit in the future. While we are not recomending enforcement action in this instance, continued violations could result in such actions. j Also, reporting requirements of the permit are not being met. The current NPDES permit requires monitoring pH from the neutralization tank and pressure filter backwash twice per month. Refer to pages 2 and 3 of the permit. As a reminder, we woul'd like to call your attention to a change in monitoring requirements which will be required for the cooling tower blow-down. These will be in effect July 1,1984 and are detailed on page Eb of your NPDES permit. Existing requirements are listed on page 4a. If you have any questions, please contact Larry Kloet of my staff at 656-4887. ' Sincerely, n} J David M. Word, P.E.

Manager of Environmental Affairs Georgia Power Company P. O. Box 4545 Atlanta, Georgia 30302 Re: f1PDES Permit tio. GA 0004120 Plant Hatch
Dear Mr. Woodall:
We conducted an inspection of the wastewater treatment facilities 1 at Plant Hatch on December 6,1984 Mr. Bob Hand and Mr. Oliver Granade were my plant contacts. Grab samples were taken from the filter backwash from Unit A and from the cooling water ditch from Unit 2. Unit 1 was shut down for p() routine maintenance. Only the sample of the cooling water was split with the company. Laboratory results for Cr and Zn matched those results for Georgia Power. Deficiencies which need to be corrected include sampling methods for oil and grease determination in water. Glass bottles should be used instead of the plastic ones now being used. If samples are not analyzed the same day they are collected, sulfuric acid should be added as a pre-servative. Operation Monitoring Reports are also being received at least a month late every reporting period. This is a violation of your f1PDES permit and steps should be taken to insure timeliness of report sub-mittal. Attached are the results of our laboratory analyses. Based on these results, you were in compliance with limitations on your flPDES ' permit. fic other problems, other than those already noted, were found. Sincerely, Q A Larry P. tloet, P.E.

Box 4545 Atlanta, Georgia 30302 RE: Notice of Violation Generator Requirements , Georgia Power Company Plant Hatch GAD 000612564 Dear Mr. Woodall Reference the inspection of November 8, 1984 by Tim Cash of the Industrial and Hazardous Waste Management Program to determine your company's compliance A status with Georgia's Rules for Hazardous Waste Management, Chapter 391-3-11 .08,
,b Standards Applicable to Generators of Hazardous Waste. As Georgia's Rules adopt and incorporate by reference the Federal Regulations found in Section 40 CFR, Part 262, the following violations are called to your attention for appropriate action:
40 CFR 262.11 - for failure to make hazardous waste determination for vaste oils generated at Plant Hatch. 40 CFR 262.34(a)(4) - for failure to describe agreements with local authorities in accordance with 40 CFR 265.52(c). 40 CFR 262.34(a)(4) - for failure to list, show the location of, describe and provide a brief description of emergency equipment at Plant Hatch in accordance with 40 CFR 265.52(e). 40 CFR 262.34(a)(4) - for failure to submit copies of the contingency plan to local authorities in accordance with 40 CFR 265.53(b). This correspondence will also serve to confirm Mr. Cash's November 20, 1984 meeting with' Glenn Gosa, Harold Hobbs, Dean Miracle and George Guill concerning the contingency plan and preparedness and prevention provisions for Plant Hatch. At that meeting, it was agreed that Georgia Power Company could reference other Power Generation Procedures in a facility's contingency plan where documentation required to comply with 40 CFR Part 262.34(a)(4) would result in unnecessary or excessive duplication of procedures which have already n been established. In a phone conversation between Harold Hobbs and Tim Cash b Aas APPIRetATIVE aCTtoel/ EQUAL EhrLOYte8NT OPPORTURIITY ERrLOYER
t
- t .3 .
2 i on December 11, 1984 it was also agreed that the contingency plan req iremer_ts of 40 CFR, 265 Subpart D and the preparedness and prevention requirements of 40 CFR 265 Subpart C should concentrate primarily upon the " satellite" accumulation areas and hazardous waste temporary storage areas at each facility. It has been determined that these areas would be significant in terms of the routine handling of hazardous vaste. You are requested to collect samples of the ' waste oil generated at this facility, conduct analyses of those samples in accordance with 40 CFR 262.11 and submit the results of those analyses to this office by January 15, 1985. You are also requested to amend the facility's contingency plan and submit a revised copy to this office for review by January 15, 1985. At the time of the inspection, it was observed that your hazardous waste manifest originals are being microcopied and destroyed when they are received from the designated facility. This practice is acceptable and may be continued. Enclosed is a copy of the Generator Standards Inspection Checklist completed during the inspection. If you have any questions or need any assistance please contact Mr. Tim Cash at 656-7802. Sin rel

interoffice Corresponcence - Georgia Poner n\ Date: June 28, 1984 LAB-84-190 Re: PLANT E. I. HATCH Sewage Treatment Plant From: B. C. Arnold. To: Harold Hobbs ' The following actions have been taken to maintain efficient operation of Plant Hatch's sewage treatment plant and to prevent the discharge of raw sewage to the environ =ent:
- 1. Blowers have been placed in hand for continuous aeration of sewage to maintain a D.O. inventory for bacterial life in the aeration tank. Without this change, the plants would start to go septic in appro::imately cne day.
- 2. Sludge has been wasted to the sludge holding tank and hauled off every other day and often daily to maintain suspended solids in the 202 to 301 range.
Otherwise, it is very hard to maintain a D.O. inventory.
. () '
- 3. The flow of sewage into the plant has been lowered as much as possible.
, 4. The settling tank has been hosed down and scraped all the way to the bottom every other day in order ' for the sludge to settle out as much as possible before release.
- 5. A representative from Burford, Hall and Smith, the designer of the system, came on June 27, 1984 to evaluate the existing systems and to make recommendations for improving plant operation.
- 6. The System Engineer has been notified of the probicms.
