- 1. WATER QUALITY MONITORING 1.1 Physical and Chemical Requirements 1.1.1 Specification The Edwin I. Hacch Nuclear Plant Operating License Stage Environmental Report requires that a dissolved oxygen and temperature sursey be conducted weekly at pre-selected stations in the Altamaha River. Also, a temporary temperature monitor was installed on a piling within the estimated mixing zone of the HNP discharge and will remain there until verification of the HNP thermal plume predictive model is completed.
1.1.2 Results and Discussion The Georgia Power Company water quality mor.itoring program of the Altamaha River consists of a weekly dissolved oxygen and temperature survey. A map of the dissolved oxygen and temperature survey stations is shown in Figure 1.1-1. The HNP discharge is located between Station 6 and Station 7 at river mile 116.2. Measurements of dissolved oxygen and temperature were taken at depths of 1 foot, 3 feet, 5 feet, 10 feet, and bottom of channel where applicable. A summary of the dissolved oxygen and tempera-()
7s ture data collected at the 3-foot level during 1981 is shown in Table l .1-1. Data collected during preoperational and during Unit 1 operational phases are presented in Tables 1.1-2 and 1.1-3, respectively. Mean dis-solved oxygen levels in 1981 were approximately 0.6 mg/l higher than pre-operational data and 0.1 mg/l lower than Unit 1 operational data. Maximum dissolved oxygen levels for 1981 were 2.7 to 3.4 mg/l higher than preoper-ational data and ranged from 0.9 mg/l higher to 0.2 mg/l lower than oper-ational data. Minimum diseolved oxygen levels for 1981 were fron 1.1 to 0.6 mg/l higher than preoperational data and 1.1 to 0.4 mg/l higher than operational data. Mean temperature levels for 1981 were approximately 0.6 C lower than preoperational data and were similar to operational data. Maximum temperatures were from 0.5 to 1.0 C higher than preopera-tional data and similar to operational data. Minimum temperatures for g981were2.3to1.6 C lower than preoperational data but were 3.3 to 2.5 C higher than Unit 1 operational data. This can be attributed to the l unusually cold winters of 1976 and 1977. The dissolved oxygen and temper-ature survey was shortened to six stations in September, 1973, and to three stations in August, 1977. The HNP thermal plume predictive model has been completed and approved by the State of Georgia Department of Natural Resources in a letter dated August 5,1981.

(" 1. 2 Thermal
_1.2.1 Specifications Temperatures of the intake water and the discharge from the cooling system to the river were measured in accordance with the Environmental Program Description Document (EPDD) as required by Section 3.1.1.1 of the HNP-ETS, Units 1 and 2. The EPDD requires that the intake water temperature, temperature of the combined plant waste streams, and mixing zone water temperature be measured on a weekly basis. This program began with attainment of normal operation of Unit 2 during September, 1979, and will continue in accordance with the requirements of NPDES Permit No. CA-0004120. The NPDES permit requires that weekly temperature measurements be taken at the intake, at the mixing chamber (last point before discharge of combined plant waste streams), and at a point 500 feet downstream of the discharge pipe. In addition, the NPDES permit states, " Georgia Power Company will initiate work on a study to field verify and/or fine tune their thermal plume predictive model not later than six months following commercial operation of Unit 2."
1.2.2 1981 Monitoring Program In accordance with the EPDD and NPDES permit, temperatures were measured on a weekly basis at the intake structure or at a midstream point upstream of the intake, at the mixing chamber, and at the downstream edge of the f3 mixing zone (approximately 500 feet downstream of the discharge point).
(,_) A complete listing of the temperatures is given in Table 1.2-1. The maxi-mum observed difference between intake and mixing zone temperatures (AT) was 2.0 F, which occurred on July 15, 1981. All temperatures measured are within the limits required by the NPDES permir (90 F maximum or 5 F rise above ambient). Deviatlan from the required weekly temperature mea-surements occurred the week of December 25, 1981, and December 30, 1981, due to equipment malfunction (see Table 1.2-1).
The field verification and fine tuning of the predictive thermal plume model required by the NPDES permit has been completed. The approval of the thermal plume predictive model by Georgia Environmental Protection Division (EPD) was received August 5, 1981. Pursuant to Section 5.7.3.1 of the HNP-ETS, Georgia Power Company has requested that Section 3.1.1.1 Thermal, be deleted from the ETS via a letter dated October 30, 1981 from J. T. Beckham, Jr. , Vice-President and General Manager, Nuclear Generation to the Director of Nuclear Reactor Regulation.

%.)
1.3.1 Specification According to Section 3.1.1.2 of the HNP-ETS, during normal station operation, the pH of the intake water and the discharge water shall.be measured as specified in the Program Description developed by the licen-see in accordance with,Section 5.6.1. This specification applies to out-fall series number 001 as specified in NPDES Permit No. GA-004120, This monitoring program shall commence with the initial atta' ament of normal operation of Unit 7. and continue until approval for termination
. or modification of this monitoring requirement is obtained from NRC in accordance with Section 5.7.3.
NPDES Permit No. GA-0004120 requires that pH be measured on the following process streams: cooling tower blowdown, sewage treatment plant effluent, liquid radwaste, low volume wa<.ce,~and combined plant waste streams (mix-ing chambers). All waste streams, except low volume waste and liquid radwaste, must meet limits of 6.0 to 9.0 standard pH units at the point of release from their respective tanks before merging into a combined plant waste stream at the mixing chamber. -Low volume waste and liquid radwaste are not required by the NPDES permit to meet the pH limits at their points of release. The NPDES permit also specifies the minimal pH monitoring frequencies as follows: pressure filter backwash once per quarter; cooling tower blowdown and low volume waste (including radwaste)
O_- twice per month; sewage treatment plant effluent twice per year, and com-bined plant waste once per. week.
1.3.2 Results and Discussion Plant intake water pH was monitored by grab samples taken from the river, upstream of the discharge. Low volume waste pH from the neutralization tank was continuously monitored at the water treatment plant. Low volume r waste pH from the pressure filter backwash was monitored quarterly by a grab sample. Liquid radwaste pH was measured twice a month on a batch basis. Low volume waste pH from the sewage treatment effluent was mea-sured daily. Cooling tower blowdown pH was continuously monitored in the water analysis rooms. Combined plant waste pH for Units I and II was monitored continuously at the plant discharge structure before being dis-charged to the river.
Tables 1.3-1 through 1.3-8 summarize the required pH measurements taken at Plant Hatch during 1981. The limits on pH as set forth in NPDES Permit No. GA-0004120 were adhered to with no violations.

1.4 Chlorine Monitoring O 1.4.1 Specification According to Section 3.1.1.3 of the HNP-ETS, during normal station operation, the discharge to the civer of free available chlorine from the cooling tower system shall be measured as specified in the Program Description developed by the licensee in accordance with Section 5.6.1.
The Environmental Program Description Document (EPDD) states that sampling will begin at the time of initial commercial operation of Unit II and will continue in accordance with the requirements of NPDES Permit No. CA-0004120. Free chlorine concentrations in both the plant service water system and the circulating water system will be measured after the chlorization ends but before blowdown begins. Blowdown will not begin until chlorine concentrations are within the limits specified in the NPDES permit. Concentrations will be determined by Amperometric titration or an equivalent method.
NPDES Permit No. GA-0004120 states that free residual chlorine discharge to the Altamaha River must not exceed an instantaneous maximum concen-tration of 0.50 mg/l or an average concentration of 0.20 mg/1.
1.4.2 Results and Discussion Samples taken at specified points are analyzed for chlorine concentration
(} by use of an Amperometric titrator and/or chlorine comparator.
The plant service water system chlorination was operated in a continous mode during 1981. Service water was diverted to the circulating water flume during chlorination to guard against chlorine releases to the river above specified limits during the chlorination period. Chlorine residuals for plant service water measured at the flume ranged from less than 0.1 mg/l to 0.75 mg/1.
The circulating water system chlorination was operated in an automatic mode during 1981. The circulating water blowdown valve was closed during chlorination. The cocling tower effluent was analyzed for free residual chlorine. The circulating water was chlorinated three times a day for approximately thirty minutes, depending on the chlorine demand for the sys-tem. Free residual chlorine was generally maintained between 0.05 mg/l and 0.20 mg/l during chlorination.
Tables 1.4-1 through 1.4-3 summarize the chlorine data for the circulating water system and plant service water system for 1981. All limits set forth by the HNP-ETS and NPDES Permit No. GA-0004120 were adhered to with no violations. However, in the quarterly NPDES reports and data sheet 2 of Hatch procedure HNP-7606, sampling location was incorrectly logged as the discharge to the river instead of discharge to the flume where the sample was actually taken (see Table 1.4-3).

- 2. RADIOLOGICAL MONITORING 2.1 Introduccion The results of the radiological environmental monitoring program for the celendar year 1981 are reported herein. An assessment of the radiological impet t of the plant's operation upon the environment is provided. Report s on various related activities are also included.
A summary, interpretation, and evaluation of the analytical results obtained from the samples utilized to monitor discharges of radioactive materials to the atmosphere , rive r, 2nd ground are provided as appropriate in Sections 2.2, 2.3 and 2.4, re spec tive ly. The data on samples required by the Environmental lechnical Specifications (ETS) are tabulated by station or group of st ations. As practical, each tabulation consists of: the maximum, minimum and average values of the radiological level; the number of samples (n); and the standard deviation (s). Nominally, summaries are provided for the concrol 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 99% confidence level between these two groups is provided for comparison with the difference in their average values, Li-Lc. Any laboratory analyses performed on environmental
(_j samples in addition to those required are also reported.
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; any significant deviations are noted.
The interpretation of results includes, as warranted and as practical, a comparison with the results found in the preoperational surveillance report and in previous operational surveillance reports. Wherever warranted, an attempt was made to provide a perspective of the results within the framework of regulatory limits, background levels, and plant re lease s coupled with dilution, dispersion and/or concentration f actors; where feasible attempts were made to correlate the plant releases with the radiological levels in the environmental samples. Efforts were made to recognize any data trends; plausible explanations are offered for any such trends considered to be significant.
Any confirmed measured radiological concentrations in an environmental sampling medium averaged over any quarterly sampling period which exceed the reporting levels given in Table 3.2-3 of the ETS are discussed.
Explanations are postulated to account for high radiological levels.

O Regular preoperational monitoring began in January 1972, following a period of: installation, calibration and checkout of the sampling equipment; the development of sampling methods and analytical techniques; and the training of personnel. The operational phase of the radiological environmental monitoring program began with initial criticality of the Unit I reactor on September 12, 1974. Initial criticality of the Unit 2 reactor was achieved on July 4, 1978.
In recent years there has been a series of detonations of nuclear devices in weapons tests on mainland China; there were also test conducted during the early months of preoperational monitoring. These occurred as follows:
Janua ry 7, 1972 March 13, 1972 September 26, 1976 Novembe r 17, 1976 September 17, 1977 March 14, 1978 December 14, 1978 October 15, 1980 Usually about a week af ter each of these tests a marked increase in the radiological level in many of the samples collected in the HNP environs was S noted giving abundant evidence of the appearance of fallout of radioactive material from the cloud created by the test. These were generally corroborated with widespread reports of similar step increases occurring e lsewhe re.
The first two years of operation (of Unit 1) was a period without significant weapons tests being conducted in the atuosphere, a time when there was a general decline in the radiological level for most of the environmental sample s. The effects ~of the 1976, 1977, 1978 and 1980 weapons test were noted in the annual environmental surveillance reports.
In Section 2.5, the results from participation in the EPA Crosscheck Program are provided. In Section 2.6 the chief conclusions drawn f rom the radiological environmental monitoring activities including the assessment of any radiological impact of the plant's operation upon the environment are p re se nted.
2.2 Discharges To The Atmosphere The media or pathways sampled to monitor discharges to the atmosphere consisted of: airborne dust, airborne iodine, external radiation, milk and g ra s s. Airbo rne 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 (O
v 2-2
O .
other locations as shown below. Starting with the 1st quarter of 1980, additional TLDs were placed in the site environs to conform with Revision 1 of the Technical Position of the Radiation Assessment Branch of the NRC, dated November 1979. The locations of these new TLDs are described in Section 2.2.3. The locations of the milk sampling stations are provided in Section 2.2.4. Grass samples were collected f rom plots maintained at Air Stations Nos. 5, 17 and 21. The sector location and distance as reckoned from the main stack to each of the air stations and to each of the TLD stations required by the ETS are as follows:
Air Stations No. 1 State Prison ENE 11.1 miles No. 5 Baxley S 9.9 miles No. 9 Dead River Road NE 1.8 miles No. 15 Roadside Park WNW 0.8 miles No. 17 Site Boundary SE 1.2 miles No. 21 Site Boundary WSW 1.0 miles TLD Stations (same as air stations plus) 7- No. 119 East Boundary ESE 1.1 miles
(_j No. 126 South Boundary S 0.9 miles No. 133 West Boundary W l.1 miles Station Nos. 1 and 5 are the control stations; the other stations are indicator stations.
All laboratory analyses of the samples collected to monitor discharge to the atmosphere are contracted to Teledyne Isotopes, Inc. of Westwood, New Jersey except for: the grc .a beta counting of airborne particulates which is performed by the plaat; the reading of the TLDs which is done by Eberline Instrument Corporation's midwestern facility in West Chicago, Illinois; and the gamma scan of grass which is provided by the Center for App' lied Isotope Studies at the University of Georgia in Athens, Georgia.
2.2.1 Airborne Dust The annual summary of the gross " beta activities for the airborne dust samples which were collected weekly is presented in Table 2.2-1. The average activity for the indicator stations is seen to be less than that for the control stations; the difference between these averages is far less than the MDD.

The following samples were not included in the data summary:
Station Collection Date Reason 9 3/10 Power Failure 17 4/20 Defective filter 5 5/18 Pump off The data for the March and May samples were considered invalid because the sampling time was low. The data for the April sample was invalidated because the filter had a hole in it and thereby became ineffective in collecting dust.
For exhibition purposes air dust samples were also collected off and on during the year at the Visitors Center. The results were about the same as those found at the other stations during the same time period.
Recent annual reports have clearly pointed out the effects of the nuclear weapons tests on mainland China upon the levels of gross beta activity in airborne dust samples collected in the environs of Plant Hatch. This may be
, seen by comparing the average weekly activity for all stations at which collections were made for each year of operations and for the period of preoperations ; these weekly averages are given below in units of fCi/m3 (femto Curie per cubic meter).
{}
Period Average Activity Preope rations 140 1974 87 1975 87 1976 137 1977 242 1978 133 1979 38 1980 48 1981 195 The' fairly high level of average activity for the period of preoperations (January 1972 to September 1974) is attributed to the weapons tests in the early seventies. The lower levels of average activity for 1974 and 1975 show the depletion of these levels due to decay or physical removal during a period without significant weapons tests. The level continued to drop into 1976; the average level of the first three quarters of 1976 was 42 fCi/m3, then the average jumped to 412 fCi/m3 for the 4th quarter of 1976 as a consequence of the detonations on September 26 and November 17, 1976. The higher level for 1977 shows the carry over of debris from the 1976 tests as well as the effects of the detonation on September 17, 1977. Despite the
~\ -
(V 2-5
(O.)
detonations on March 14 and December 14, 1978, the annual average level for 1978 dropped to about half of that for 1977. The annual average dropped greatly in 1979 to the levels experienced early in 1976. The average level through the first 10 months of 1980 and 32 fCi/m3; the average for the remainder of the year was 137 fCi/m3 which clearly shows the effects of the October 15 detonation.
The ef fects of the October 15, 1980 detonations were strong in the first half of 1981 especially during,the spring when there was mixing of the air f rom higher to lower altitudes. The highest weekly average gross beta activity was 768 fCi/m3 for the collection on April 13; this is well below the all time maximum weekly average of 3700 fCi/m3 which occurred for the collection of October 3-4, 1977. The quarterly averages were 340, 330, 67 and 48 fCi/m3 for the 1st through the 4th quarter respectively. The average weekly reading was down to 20 fCi/m3 for the last week of 1981.
The activities of specific radionuclides detected in quarterly composites of airborne dust filters by gamma spectral analyses are summarized in Table 2.2-2 for the entire year. The levels are typical of or on the order of those found previously. All except Cs-134 whose LLD is nominally 0.4 fCi/m3 had been previously detected. The dif ferences between the average levels at the indicator and control stations are small; each of these dif ferences is below its MDD.
V The presence of each of the radionuclides except naturally occurring Be-7 and K-40 is attributed to the nuclear weapons tests, especially the most recent detonation. For the manmade radionuclides: the levels were high during the first two quarters ; in the 3rd quarter, the levels dropped substantially, below the LLD in most cases; in the 4th quarter, only Cs-137 was detected but at only half of the stations.
2.2.2 Airborne Iodine The charcoal cartridges used for filtering iodine f rom the atmosphere were collected weekly and analyzed for I-131 by Ge(Li) spectroscopy. The activity found in each sample during the entire year was below the LLD which never exceeded 70 fCi/m3 (the maximum allowed by the ETS).
Du ring 1976,1977 and 1978 detectable levels of I-131 were found for a period of a few weeks af ter the arrival of the cloud f rom each of the nuclear weapons tests. The highest level ever f ound was 217 fCi/m3 in 1977. The reporting level called for by the ETS is 900 fCi/m3, i

2.2.3 The rmoluminescent Dosimeters External radiation is monitored by thermoluminescent dosimeters (TLDs). The total dose acquired by the TLD badges consists of that received when on-station and that received when off-station (that is, in transit, in storage and in handling). It has been assumed that a fair estimate of the of f-station component may be provided by the average dose acquired by the extra badges which accompany each batch of badges during shipment and temporary periods of storage, and which have been kept in a Pb cave at the plant while the regular badges are on-station or in transit to their re spec tive stations in the field. The on-station dose has been approximated by subtracting the average dose of these "nonirradiated" extra badges f rom the total dose reading of each regular field badge before nonnalizing to the desired exposure period. Although the validity of this method may be questioned, it was shown in the 1975 report that generally the on-station doses were more consistent th roughout the year and provided better correlation between the doses acquired over various periods of exposure than the total doses.
The on-station dose is fundamentally of more interest than the total dose because it is closer to what is being sought, which is, the dose that might be acquired by external radiation as a consequence of gaseous releases f rom
() the plant. Each badge in the field is subjected to local background radiation which consists of terrestrial radiation f rom naturally occurring radionculides, cosmic radiation, and radiation due to fallout from weapons tests. The large variability in both space and time of each of these components of the . local background radiation makes it difficult to discern any part of the on-station dose which can be attributed to plant releases, which part is generally anticipated as being much smaller.
The locations of the TLDs by sector and by distance f rom the main stack in miles are provided in Table 2.2-3. At the beginning of 1980, an attempt was made to establish two TLD stations in each sector (in accordance with the Branch Technical Position dated, November 1979), one near the site boundary i and the other at a distance of about four or five miles. In addition a TLD was placed at Toombs Central School in the North Sector at 7.8 miles and there is a TLD at the roadside park in the WNW Sector at 0.8 miles.
Suitable locations were not found in the East Sector. The control stations, Nos. 1 and 5, are respectively ENE at 11.1 miles and S at 9.9 miles. Two badges are placed at each station.
l The "nonirradiated" badges were not handled with suf ficient care during 1981. The 3rd quarter "nonirradiated" badges were not returned to the cont ract lab for counting with the other 3rd quarter badges; they were returned with the 4th quarter badges. For other qua rters, readings for the "nonirradiated" badges were higher than some or many of the " irradiated" badges. It thus became necessary to estimate the of f-station dose. In
("'
making this estimate, consideration was given to the range of readings, the expected reading, the extent of the period between the date of annealing and the date of reading, and previous results.

The annual summary of the on-station doses acquired by the TLDs which are required by the ETS is presented in Table 2.2-4. The average dose for the indicator stations is seen to be a little greater than that for the control stations. The absolute value of the difference between these values is much less than the MDD, meaning that this difference is not discernable.
Missing from Table 2.2-4 are the TLDs for Stetion 9 in the 1st qua rt e r, Station 133 in the 2nd quarter, Station 15 in the 3rd quarter, and Stations 5 and 21 in the 4th quarter. TLDs are f requently lost due to thef t and are frequently damaged by vandalism. To diminish the frequency of missing or damaged badges, TLDs are placed in less conspicuous places whe rever this is p rac tical. Failure to collect TLDs in such cases is considered as a pe rmissible deviation from the requircd sampling schedule.
The annual summary of the on-station doses acquired at the site boundary and at 4-5 miles is presented in Table 2.2-5. The average dose for the site boundary is seen to be slightly greater than the average for the 4-5 mile ring. However there is no discernable dif ference between these two values.
The on-station quarterly doses acquired by the TLDs placed at Station 31 (Toombs Central School) ranged from 4.0 to 8.6 mrem with 6.0 mrem as an ave rage.

. Milk The ETS which were revised in 1978 specify biweekly collections from one control station and f rom one to four indicator stations depending upon the availability of milk animals near the plant. The state prison was specified as the control station and Stones dairy was designated as an indicator station since it had been the closest reliable station. Up to three g , additional indicator stations within five miles and in different sectors are
'i <
.also spacified, if available; Williamsons has been the only location to meet
/ this specification.
As related in the 1979 report, Stones dairy was deleted from the program as milk became unavailable in the latter part of April (1979) with this dairy going out of business; Stones dairy was replaced with Sellers dairy. At the end of May (1981), Sellers dairy went out of business; Sellers dairy was replaced with Johnson Brothers dairy without missing a collection period.
l Johnson Brothers dairy is a mile further away fr~n the plant than Sellets t dairy, but in the same sector. This 8.5 mile Li s < nc a may be a litt le f ar for this location to be considered as an i-ic, Itm st3cion.

V The location of the milk sampling stations for 1981 and the number of samples collected were as follows:
Sector Azimuth Distanc e n Station (Compass) (deg ree s ) (miles)
Prison ENE 067 11.0 26 Johnson Brothers SW 223 8.5 15-Selle rs SW 226 7.5 11 Williamsons NNE 029 3.2 24 No sample was available at Williamsons on February 16 and October 26.
Occasionally milk samples simply will not be available from a family's single cow. Camma isotopic and I-131 analyses were performed on each sample. This was the fourth year for the gamma scans.
There were no positive indications of I-131 in any of the milk samples during the year. This is the second calendar year since operations began that this has occurred; the first such year was 1979. Previous levels have ranged from 0.095 to 88 pCi/1. All significant readings were generally attributed to the weapons tests. The other readings were marginally
/'] detectable or questionable. During preoperations all readings were less k/ than the LLD of 2 pCi/1; the LLD was subsequently lowered to 0.8 pCi/1.
The gamma scans showed naturally occurring K-40 present in each sample at levels which varied between 646 and 1780 pCi/1. These levels are about the same as those found previously.
The gamma scans also showed positive indications of the fission product Cs-137 in a quarter of the samples collected, as compared to a third in the previous year. The levels were found to be somewhat lower also. The results in pCi/l for each station are summarized as follows :

The ratio, n/n o, the number of positive results to the number of analyses performed, shows relatively high f requencies of positive results for Johnson Brothers and Sellers. With the re quired LLD at 15 pCi/1, most of these positive measurements are only marginally detectable. The highest level given above is considerably less than the reporting level of 70 pCi/l given in Table 3.2-3 of the ETS. The positive levels found during the past th ree years ranged from 8 to 57.1 pCi/1 with the average values for the stations ranging f rom 11.4 to 20.9 pCi/1. During preoperations, Cs-137 was measured in milk by a chemical separation technique; the levels ranged from 2 to 60 pCi/1 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.
The ETS require that a survey be conducted annually to determine the location of all milk animals within 3 miles of the plant stack in each of the 16 azimuthal sectors. For any of the 16 sectors in which milk animals are not found within 3 miles, the annual survey is expanded to locate the nearest milk animal within 5 miles in that sector. A milk animal is a cow or goat which is producing milk for human consumption. On May 6 and 7, the milk animal survey was conducted. The only milk producing animal found was the cow at Williamsons which is presently being sampled.
t( ) 2.2.5 Grass Gamma isotopic analyses were performed on each of the grass samples collected monthly from the three sampling stations. Positive identification of several radionuclides were determined. These have been separated into five groups as follows:
(1) Be-7 and K-40; (2) Zr-95, Nb-95, Ru-103, Cs-134, Cs-137, La-140, Ce-141 and Ce-144; (3) T1-207; (4) Pb-214 and Bi-214; and (5) T1-208, Pb-212 and Ac-228.
Only in the second group are there man-made radionuclides. An annual summary of the activities of these radionuclides is provided in Table 2.2-6. It is seen that there are no discernable dif ferences between the average values at the indicator stations and the control station.
K-40 was detected in every sample. Be-7 was detected in all but two of the samples. The levels were on the same order of magnitude as those found previously but a bit lower than those found last year however, (q

Generally Cs-137 is the only fission product detected and it is generally detected in about 70% of the samples. During 1981, Cs-137 was found in more than 85% of the samples; however, the leve ls we re , in general, considerably lower than those found in 1980.
In December 1980, Zr-95, Nb-95, La-140 and Ce-141 suddenly appeared in all of the samples. This was attributed to the nuclear weapons test conducted on October 15, 1980. These fission products continued to be present in 1981; in addition, Ru-103, Cs-134 and Ce-144 appeared. All of these radionuclides except Zr-95 and Cs-134 appeared in samples collected in 1978 and their presence was attributed to the weapons test conducted at that time. In gene ral, the levels found in 1981 were on the same order as those found previously. Also, the levels were generally higher in the spring which reflects the usual mixing of air f rom higher to lower altitudes at that time of year; subsequently, the presence of the samples began to fade.
By year's end, modest levels of Nb-95 and Ce-144 were found in only one sample; Cs-137 continued to be found in all three samples; no other fission products were detected.
Each of the radionuclides in the last three groups is a primordial nuclide.
None of these radionuclides is produced by operation of the plant. T1-207 is in the Actinium Series; the presence of this radionuclide in the November
() sample from Station 17 is its first appea rance. The radionuclides in the second to last group are from the Uranium Series. Those in the last group a re f rom t he Tho rium Se rie s. Each of the radionuclides in the Uranium and Thorium Series had been found in soil samples taken f rom each of the grass plots on November 10, 1977. The levels are on the same order of those found p re vious ly.
The ETS requires an LLD of not greater than 25 pCi/kg wet for I-131. This i limit was exceeded on eleven occasions as follows:

Iodine has a strong affinity for water; the moisture content in these samples was low due to very dry weather. These deviations are not l
considered as significant.

An adequate sample was not available at Station 17 in March due to dry
- we at he r. The sample collections at all stations in June, November and December were respectively 38, 43 and 22 days following the collectins for the previous month. These spreads in the collection dates constitute a deviation f rom the ETS in that Table 3.2-1 requires monthly collections for grass samples; monthly is defined as once each calendar month at intervals of 30 days 1 6 days. A closer watch of the sampling schedule should prevent further deviations of this kind. This deviation is insignificant.
2.3 Discharges To The River The ETS require the sampling of water, clams and sediment f rom Rive r Stations 170 and 172 which are about 1 1/2 miles upstream and 21/2 miles downs t re am, re spec tive ly. The upstream station serves as the control station and the downstream station serves as the indicator station. The ETS also require the sampling of American shad f rom the area of the discharge st ruc tu re.
The ETS require a gamma 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 are performed by Teledyne Isotopes, rg Incorporated of Westwood, New Jersey.
()
2.3.1 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 picked up monthly; quarterly composites are composed of the monthly collections.
Table 3.2-1 of the ETS requires monthly collections. In effect the sampling of river water is continuous and the accumulated collections are nominally
! gathered at intervals of approximately one month. Monthly is defined by the ETS as once during each calendar month at intervals of 30 days 1 6 days.
This definition is appropriate for grab sampling and does not fit perfectly when applied to continuous sampling. The monthly collections on February 4 and 25, June 24 and January 8 (1982) were respectively 42, 21, 21 and 44 days following the previous collection dates. These are minor deviations i f rom the sampling schedule. A closer watch of the sampling schedule should l p reve nt further deviations of this kind.
The sample for December never reached the contract la bo ra to ry . United Parcel Service reported the package containing the December sample was damaged and the entire contents was discarded. A sufficient quantity was not kept in reserve to provide a make-up sample. A closer watch is to be maintained to lessen the probability of any future deviations f rom procedures of this sort.

There was only one positive result for the entire year on the gamma scans of the monthly collections. Naturally occurring Th-228 was detected at a level of 21.5 pCi/1 at Station 170 in February. Its LLD is nominally 10 pCi/1.
Only scant results have been obtained in the past with this analysis.
During preoperation traces of K-40 and radon daughter products were detected occasionally. Since operation began: K-40 and Th-228 were detected in the 3rd quarter of 1974, Ce-141 was detected during the 4th quarter of 1975 and Th-228 was detected in December 1980.
The ETS require that the detection capabilities listed in Table 3.2-2 shall be achieved. The LLDs for several of the radionuclides in the gamma scan of the November sample were higher than those listed in Table 3.2-2 as shown below.

(} Ba-140 50 25 Plant procedures require that one gallon of the sample be shipped to the contract laboratory, but only 2.2 liters arrived. This possible procedure violation was called to the attention of appropriate plant personnel. The contract laboratory consumed 2 liters in performing an I-131 analysis by techniques of radiation chemistry, leaving only 0.2 liters for a Ge(Li) scan. The sample was counted for nearly 3 days rather than merely overnight as is done normally. This lack of poor judgment in leaving such a small
, part of the sample for a gamma scan was called to the attention of the contract laborato ry. This deviation is considered to be of a minor nature.
The positive results in units of pCi/1 for the tritium analysis of the quarterly composites is summarized as follows for the control and indicator station, respectively:
n_ Max Min g s L_ii MDD 4 190 100 135 39 4 300 160 220 59 85 131 Although the average reading for the indicator station was greater than that for the control station, the difference between the average values for the two stations is less than the minimum detectable difference which indicates there is no discernable difference between the values obtained at the two j (~ stations. These values are typical of and within the range of those found
- \~)N p reviously. As pointed out above, the December sample was lost in shipment; the 4th quarter composite consisted only of the October and November samples.

O In accordance with the ETS a survey was conducted downstream of the plant on September 30 to determine if water from 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.
2.3.2 Clams The ETS require a semiannual sampling of asiatic clams from the two river stations. Collections were made on May 28 and November 9. The gamma spectral analysis showed positive levels only for K-40 and Zn-65 in the May collections.
The levels for naturally occurring K-40 were 1.01 and 1.04 pCi/gm wet at Stations 170 and 172, re spec t ive ly. This radionuclide occasionally appears in clam samples. The highest reading found was 1.25 pCi/gm wet at Station 170,in the fourth quarter of 1976.
Manmade Zn-65 appeared only at Station 172 at a level of .239 pCi/gm wet.
The LLD is nominally 0.05 pCi/gm wet. This measured level is equivalent to an annual dose of 0.018 mrem to the liver of an adult; a clam consumption of 5 kg per year was assumed; this provides the maximum dosage to an
(#
) individual. This calculated dose is well below the design objective of 10 N-mrem per year to any organ for liquid effluents as specified by Appendix I to 10 CFR 50. Man-made Zn-65 has not been previously detected in clam samples; in fact, 't has never appeared in any of the environmental samples, aquatic as well as atmospheric. The sample was counted twice on dif ferent detectors for conformation; the second measurement was 0.144 pCi/gm wet.
The semiannual effluent release report for the first half of 1981 shows a total of 21 mci of Zn-65 released in liquids to the river. In the second half of 1981, a total of 32.6 mci of Zn-65 was released. Generally, the
' semiannual release of Zn-65 has been only a few mci; an exception was the first half of 1977 when 9 mci were released. A rough calculation of the Zn-65 concentration in clams at this indicator station due to the releases in the first half of 1981 indicates the level to be several hundred times lower than that measured. Thus there is no correlation between the Zn-65 releases and the measured value in clams. The measured value is attributed to the weapons test of October 15, 1980. There also exists the possibility of contamination of the sample in its handling at the contract lab. In Table 2.5 of NCRP Report No. 50 (Environmental Radiation Measurements, 12/27/76), Zn-65 is classified as a widely distributed man-made radionuclide owing its orgin to nuclear explosions and to nuclear facilities.
2.3.3 American Shad Because of its commerical importanca, the ETS require that American shad be collected annually during the spring spawning period. The collection was
(^} made on March ' 7. Naturally occurring K-40 was the only radionuclide l
\- detected in this single sample. The level was 2.66 pCi/gm wet which is l about the same as that found previously. Only K-40 has been found in l previous samples of American shad.

2.3.4 Sediment The annual collection of sediment samples took place on May 28. The positive results of the gamma scan on each sample are presented below in units of pCi/gm dry.
Radionuclide Station 170 Station 172 Be-7 1.50 K-40 9.06 15.70 Zr-95 0.28 0.86 Ru-103 0.22 Cs-134 0.28 Cs-137 0.11 0.59 Ce-144 1.29 Ra-226 4.Q2 Th-228 1.35 2.24 The levels of each of these radionuclides are typical of or on the order of those found in past years. The naturally occurring Be-7, K-40, Ra-226 and Th-228, as well as, the fission product Cs-137 appear regularly in sediment samples. All of the others have appeared previously but infrequently; none p) of these was present in the June 17, 1980 sample; Cs-134 has not appeared
(_/ since preoperations; each is a fission product (or the daughter of a fission p roduc t) . As in past years the presence of these fission products is attributed to the nuclear weapons tests. It is noted that each of these fission products appeared in the airborne dust and the grass samples collected in the first part of 1981 and likewise the presence of each is specifically attributed to the October 15, 1980 nuclear weapons test.
2.4 Discharges to the Ground i As reported in previous annual reports and also by LER No. 50-321/1979-021 (including its revisions, quarterly updates and other supplements) tritiated groundwater is located in two separate and hydraulically unconnected areas of the plant yard, namely, the area north of the Turbine Building and an i area centered just south of the Condensate Storage Tank for Unit 1 (CST-1).
Also told in these previous reports were the identification of the extraneous source of tritium for each of these key areas, and the elimination of one of these ' sources, that for the area north of the rurbine Building. The source of the tritium in the CST-1 area is the leakage from the condensate transfer pumps and associated plumbing. During 1980 dykes were erected around the CST-1 pumps and also around the CST-2 pumps; this should have precluded water from any future leaks from entering the ground.
A portion of the tritiated groundwater slowly makes its way to the river via the drainnge systems; the tritium levels in these continuous releases are a 7- few ordert. of magnitude below the high levels found in the plant yard and g_ ,, several arders of magnitude below that permitted by regulation. The offsite i doses due to these release are miniscule. Thus, there has been no significant impact upon the public's health and safety due to these high onsite tritium levels.
I l 2-20
There are three distinct water zones underlying the site: a water table, a local aquifer and a regional aquifer. Aquicludes separate and hydraulically isolate these zones from each other. The vast regional aquifer whose top is a few hundred feet below plant grade is not hydraulically connected to surface waters in the vicinty of the site. The shallow local aquifer is separated from the regional acquifer by an aquiclude which is about 100 feet thick; the top of the local aquifer is roughly 65 feet below the grade of the plant yard; it is hydraulically connected to surf ace waters in the plant environs. The foundations for some of the buildings at the plant enter but do not rupture the aquiclude between the local aquifer and the water table; this aquiclude is 40 to 50 feet thick. The water table which is charged by the percolation of precipitation through the soil is unconfined. In the plant yard the water table more or less extend from 10 to 20 feet below grade.
The water tabl*, according to the natural terrain, will drain both in a ,
northerly direction toward the river, and also in an easterly (downstream) direction toward a swamp area which drains to the river. An analysis of the water levels from various shallow test holes about the plant yard shows that groundwater flow in the water table has a strong local flavor. This phenomenon is attributed to the excavations performed during construction of the plant and the field routing of water pipes and electrical conduit runs .
These pipe and conduit runs are supported by compacted sand; any water
(~}/
s_ introduced nearby will follow a path along the run, as this is the path of least resis tanc e. Mo reo ve r, it is likely that some of the excavations formed pockets in the aquiclude between the water table and the local aquifer in which groundwater accumulates. Movement of water out of these pools might occur only when the pockets fill and overflow.
Two separate subsurface drainage ditches, whose outfalls are at about 25 feet below grade, provide a system for controlling the level of the water l
table. This network of subsurface ditches encircles the complex of the main plant buildings - the service, turbine, reactor, control, and radwaste buildings for each unit. Roughly 70% of this encirclement is serviced by Subsurface Ditch No. 1 (SSI) whose outfall is north of the plant; SS2 whose outfall is east of the plant serves the remainder of the encirclement.
The surf ace drainage system includes a network of catch basins connected by uc ' .rground ditche s. Runoff from the building roofs and the plant yard flow into these catch basins. The outfall for the surf ace ditch north of the I plant is referred to as Yard Drain No. 1 (YD1); YD2 is east of the plant.
! These two surf ace ditches are separate from each other.
l Groundwater samples are sent to the Center for Applied Isotope Studies at l the University of Georgia in Athens, Georgia. A liquid scintillation i
detector is used to determine the tritium content. Results are usually obtained within a few weeks; LLDs of about 100 pCi/l are attained.

In subsequent subsections, data summaries for the year are presented for the groundwater samples taken from the locations associated with each of the two key areas and for other locations. Nearly all of the locations are shown on Figure 2.4-1. For each sampling location, the maximum and minimum tritium levels are presented along with an average value of the positive readings and the ratio of the number of positive readings to the total number of re ad ing s . The annual average was determined by averaging the quarterly ave rage s . Other information or datum associated with the particular area may also be presented. Where warranted an assessment is provided for specific sampling locations. Any significant events or activities associated with these areas are discussed.
2.4.3 Area North of the Turbine Building The cause of the high tritium levels in this area was eliminated on March 21, 1979 as has been previously reported. It was discovered that process water had been entering the ground a few yards from Pl7B through an open ended half inch line buried to a depth of about 8 inches. Sampling locations affected by this extraneous source of tritium are: test holes N9B, P15B, Pl7A, Pl7B and T2 through T8; outfalls SSl and YDl; and manhole MHil. Test hole Pl7A taps the local aquifer, all other locations esp the water table. The manhole provides access to Subsurface Ditch No. 1. A data
~
summary of the tritium levels for each of these locations is presented in k'- /S Table 2.4-1.
Overall the levels in this area are on the decline. The main body of the tritiated water appears to have shif ted from P17B to T4 and then to N9B.
Peak readings in units of pCi/l were : 2.97 E5 at Pl7B in February 1979, 2.05 E5 at T4 in August 1979 and 2.08 E5 at N9B in May 1980. The average readings for 1981 were 8.68 E3 at Pl7B and 8.01 E3 at T4 and 9.25 E4 at N9B. The level at N9B had dropped to 8.17 E4 in June of 1981, but subsequently rose to 1.14 E5 in December. Adjacent to N9B are test holes T3 and T8 where the readings are also high. The readings at T3 increased slightly during the year while those at T8 declined significantly. The readings at both N9B and T3 were at reportable levels during the entire year.
A new high reading of 2.91 E3 pCi/l is noted for Pl7A. The previous high of 7.90 E2 pCi occurred in January 1979 when the readings were very high at Pl7B which taps the water table above the point where Pl7A taps the local acquifer. If care is not taken to properly rinse the sampling equipment after taking a sample, the next sample to be taken may be contaminated by the previous sample. It is suspected that either this sample had been so cross contaminated or it had been mislabeled.

2.4.2 CST-1 Area The CST-1 area is centered about test hole P16 which is located about 5 yards south of the CST-1 dyke and several yards east of the condensate transf er pumps. A pool of tritiated water appears to be trapped in a pocket of the aquiclude which underlies this area. Sampling locations affected by this pool are: test holes N7A, N10B, NilB, N12B, P16, T10 through T16, T18, T20, and T21; outfalls SS2 and YD2; and catch basins PY12 and PY24. Test hole N7A taps the local aquifer, all other locations tap the water table. A data summary of the tritium levels for each of these locations is presented in Table 2.4-2. This data should be re-iewed in the light of related events and activitie s.
In general, the levels declined throughout this area during the first half of the year. Only the levels at test holes P16 and T18 were reportable.
The levels at these two locations have been reportable for a few years and they continued to be reportable throughout 1981. -
A leak to one of the Unit 1 condensate transfer pumps began on July 6 and was repaired on July 16. The water f rom this leak appeared to be contained in the dyke. The dyke was drained to radwaste. Beginning with groundwater samples collected on July 17, the re was a step increase in the tritium levels by a few orders of magnitude at test holes T10 through T13.
/~% Subsequently lesser increases occurred at other nearby sampling points. The levels at test holes T10 through T13 were reportable in the 3rd and 4th qua rte rs. However, at year's end the level at each of the locations had dropped by one to two orders of magnitude f rom its maximum.
An investigation began to determine the cause of these large increases. The integrity of the discharge lines of the condensate transfer pumps, of the drain lines to the dyke, and of the dyke itself were all suspect.
Hydrostatic pressure tests were applied to the discharge lines of the condensate transfer pumps and to the dyke's drain lines. None of these lines were able to hold pressure for a sustained period. These results are inconclusive since valves are located in the pressure boundary and either -
piping or valves could be leaking.
On September 30 about 100 gallons of CST-2 water containing about 0.168 mci of tritium leaked onto the ground f rom a penetration in the dyke wall. As a pre cautiona ry measure , the dirt in the immediate area of the spill was remo ved. Gamma scans of the dirt indicated minimal amounts of activity (less than 10 pCi/gm). The cause of the event was due to a pump seal failure and to an open penetration in the dyke. The pump seal was repaired and the dyke penetration was plugged.

V Although the annual average level in samples taken from SSI was about 50%
higher than that from SS2, the highest individual reading and the highest quarterly average were found at SS2. This high reading of 6.87 E5 pCi/l is more than a factor of 400 below the MPC for tritium in unrestricted areas as given in 10 CFR 20. This reading taken in November is a new maximum for this location; the previous maximum of 5.74 E3 pCi/1 was taken in February 1980. Although this high November reading might be attributed to cross contamination, there could be some connection with the other high readings in the CST-1 area at that time. The highest quarterly average concentration at SS2 was 2.42 E3 pCi/1; this is equivalent to a dose of 0.063 mrem. This dose estimate is very conservative because it assumes that some individual were to obtain all of his drinking water directly from the outfall which is generally inaccessible. The quarterly dose limit resulting from liqaid releases as established by Appendix I to 10 CFR 50 is 1.5 mrem. The average annual concentration of tritium for drinking water in community water systema is required to be less thun 2 E pCi/l according to EPA's National-Interim Primary Drinking Water Regulations, 40 CFR 141.16.
2.4.3 Other Locations Other locations f rom which groundwater samples were collected have not been contaminated with tritium. Of these locations, test holes N8A and P15A tap the local aquifer, all others cap the water table. A data summary for each
() of these locations in units of pCi/l is as follows:

ATTACHMENT 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 p rog ram.
In these criteria, the judgement limits are variable in relation to the comparison of the Reference Laboratory's value to its associated one sigma uncertainty. As this comparison, referred to as " Resolution", inc reases ,
the acceptability of a licensee's measurement should be more selective.
Conversely, poorer agreement should 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 reported 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.

(ss) 2.6 Conclusions This chapter has shown the licensee's conformance with the radiological portions of the ETS. It has shown that all data were carefully examined. A summary, an interpretation and an evaluation (where warranted) of the results of the labortatory analyses for each type sample collected have been p re se nt ed.
A measurable radiological impact upon the environment as a consequence of discharges to the atmosphere and to the river was not established. The radiological impact of the nuclear weapons teat conducted on October 15, 1980 by the Peoples Republic of China was evident in airborne dust, grass, river sediment and clam samples during the first part of 1981.
The environmental impact of the high tritium levels found in ground water samples during 1981 continues to be minuscule.
The relevant comparisons of the analytical measurements made by HNP and cont rac t laboratories with those made by EPA in the Crosscheck Program showed Agreement in all cases.

\j HNP ANNUAL REPORT
- 3. METEOROLOGICAL MONITORING 3.1 Specification
'The on-site meteorological monitoring program is carried out as recommended by the USNRC Regulatory. Guide 1.23.
3.2 On-site Meteorological Monitoring Program The on-site meteorological monitoring instrumentation, data acquisition, and maintenance and calibration programs are as described in Section 3 of the HNP-1 Semi-Annual Report for September - December, 1974, and Section 2.3 of the RNP-1 Final Safety Analysis Report.
3.3 Data Sunnaries - 1981 Joint frequency tables of wind speed and direction by stability category for the 150-foot and the 75-foot level are presented in Tables 3.2-1 and 3.2-2. Wind roses for 150-foot and 75-Foot levels are shown in Figures 3.2-1 through 3.2-10. These are shown as annual and quarterly. wind roses.
Ambient temperature and dew point temperature are shown in Figures 3.2-11
~
and 3.2-12. There are presented as the average maximum, the average, and
(,-~,v
) the average minimum for each month. Monthly and_ annual precipitation totals are shown'in Table 3.2-3. The percent data recovery for the para-meters is shown in Table 3.2-4.
3.4 Comparison of 1981 Data The Plant Hatch meteorological data for 1981 compares very well with previous years. Data recovery for wind speed and direction 75 feet versus delta temperature 150-23 feet and wind speed and wind direction 150 feet versus delta temperature 150-33 feet were 94% and 90%, respectively. Data recovery for individual parameters average about 97%. The wind roses from 75 feet and 150 feet for 1981 compare quite well with previous years. The only minor difference is that there was more northeast and less southeast winds. The ambient and dew point temperatures compare well except for normal year-to-year variations. During 1981, the temperatures started out colder than normal and rose rapidly causing an unusually warm June which was followed by a colder than normal Augus't. The. remainder of the year was normal.
The joint frequency tables agree excellently between 1981 and previous years. There were more hours unstable meteorology (A-D stabilities) than in previous years. ' Die precipitation total of 31.72 inches was about 10 inches below normal. Precipitation totals throughout the east and south-east United States were generally about 10 inches below annual normals.

HNP ANNUAL REPORT
- 4. BIOLOGICAL MONITORING 4.1 Aerial Remote Sensing .
4.1.1 Specification Aerial remote sensing of the HNP site was conducted according to the HNP-2-ETS 3.1.2.2.1 as follows:
Plant communities of the site shall be aerially photographed to detect and assess the significance of damage, or lack thereof, related to deposition of cooling tower drift. Reconnaisance and aerial photo-graphic inspection of plant communities in the drift field are the methods recommended for detecting possible adverse effects of drif t deposition on vegetation.
4.1.2 Results and Discussion Color and color infra-red aerial photographs were made of the HNP site at approximately 1:15 p.m. on November 16, 1981. A Zeiss RMK15/23 six-inch focal length mapping camera was used with Kodak aerochrome inf ra-red 2443-Estar base film. The prints are stereoscopic pairs with
() 1" = 1000' scale. The flight altitude was approximately 6000 feet. The film is sensitive to green, red, and infra-red. The photographs were examined with a stereoscopic viewer for the occurrence of stressed vege-tation related to deposition of cooling tower drif t. No areas of dead or stressed vegetation were observed on the IR aerial _ photographs or found on the field reconnaissance survey conducted December 15 and 16, 1981. This monitoring program has been conducted as specified in the HNP-2-ETS for the two required years. Since no effects have been noted during the two-year program, no further IR photograph surveys will be conducted, and the requirement will be terminated.

HNP ANNUAL REPORT
- 5. ADMINISTRATIVE CONTROLS 5.1 Specification In accordance with Section 5. 7.1 of the HNP-ETS, Units I and II, the HNP Annual Environmental Surveillance Report will include a summary of all instances of Environmental Technical Specifications (ETS) noncompli-ances and corrective action taken, changes in federal and state permits and certificates, changes in the Environmental Program Description Docu-ment (EPDD), changes in station design or operation which could involve an environmental impact, changes made to the ETS, and copies of all re-ports regarding station discharges made in accordance with NPDES Permit No. CA-0004120.
5.2 Discussion In accordance with Section 3.1.1.1 of the HNP-ETS and the EPDD, weekly temperature measurements will be taken of the intake water, combined plant waste streams, and discharge water at the mixing zone. Tempera-tures were not taken the week of December 25, 1981, or December 30, 1981, due to equipment malfunction.
The expiration date of the NPDES Permit No. GA-0004120 has been extended
() to December 31, 1982, via a letter dated July 28, 1981, from J. Leonard Ledbetter, Director, Georgia Department of Natural Resources, Environmental Protection Division, to T.E. Byerley, Manager of Environmental Affairs, Georgia Power Company.
There were no changes in station design or operation in 1981 which could involve an environmental effect.
Pursuant to 10CFR50. 90 and Section 5.7.3.1 of the HNP-ETS, Georgia Powar Company requested a change to the ETS via a letter dated October 30, 1981, from J. T. Beckham, Jr., Vica-President and General Manager of Nuclear Generation to the Director of Nuclear Reactor Regulation. The first pro-posed change is to delete Sections 3.1.2.1.1, Benthic Macroinvertebrates; 3.1.2.1.2, Entrainment of Ichthyoplankton; and 3.1.2.1.3, Impingement of
- Organisms. Required surveillance for these sections has been completed.
The seconu proposed change is to delete Section 4.1, Erosion Control In-spection. It is the opinion of Georgia Power Company that the required soil-vegetation stabilization has been attained. The third and final pro-posed change is to delete Sections 3.1.1.1, Thermal; 3.1.1.2, pH; and l 3.1.1.3, Biocide, since these sections essentially duplicate ef fluent
! monitoring requirements set forth in NPDES Permit No. GA-0004120.
Copies of all reports regarding station discharges made in accordance with I NPDES Permit No. GA-0004120 are included in Appendix A.
