SUMMARY
During the first quarter of 1985 the Environmental Technical Saecifications for Calvert Cliffs Nuclear Power Plant Units 1 and 2 were changed substantially. Under these Technical Soecifications samoles were still taken from the aquatic, atmosoheric, and terrestrial environments with the
- emchasis on critical pathways. In many cases, however, sample locations, samole types, and/or samoling frequencies were changed considerably from that found in the previous Environmental Technical Soecifications.
A total of 780 analyses were performed on 651 environmental samples during this operating period. In addition 1,020 thermoluminescent dosimeters (TLD's) were analyzed for ambient radiation exposure rates.
Samples from the aquatic environment included bay water, fish, shellfish, i sediment, and shoreline sediment. Under the old Technical Specifications bay water was analyzed for tritium, Sr-89. Sr-90, and gamma emitting nuclides. Fish, shellfish, and sediment were to be analyzed for gamma j emitting nuclides. Fish bones and sediment were also to be analyzed for I Sr-89 and Sr-90. Under the new Technical Specifications bay water was analyzed for tritium and gamma emitters. Fish, shellfish, and shoreline sediment were analyzed only for gamma emitting nuclides.
. Monitoring of the atmospheric environment included samoling air. and crecipitation. Air car,ticulates and gaseous iodine were collected on glass i fiber filters and silver zeolite molecular sieve cartridges, respectively.
Under the old Technical Soecifications the particulate filters were analyzed for gross beta activity and for gamma emitting nuclides, while the molecular sieve cartridges were analyzed for I-131. Analyses were made fcr Sr-89 and Sr-90 on quarterly composited air oarticulate filters. j Precipitation was analyzed for gross beta, H-3. Sr -89. Sr-90, and gamma l emitting nuclides. Under the new Technical Specifications the particulate l filters were analyzed for beta activity and gamma - emitting nuclides. The !
molecular sieve cartridges were analyzed for. airborne I-131.
Under the old Technical Specifications, samples from the terrestrial !
environment included milk, vegetation, soil, and ground water samples. Milk
- samoles were to be analyzed for gamma emitters,1-131. Sr-89, and Sr-90. !
The vegetation and soil samoles were to be analyzed for gamma emitters, l Sr-89, and Sr-90. The ground water samoles were analyzed for H-3 and ;
gamma emitters. Under the new Technical Soecifications only vegetation '
samoles were collected and analyzed for gamma emitters and I-131.
Measurements of external radiation were performed by analyzing TLD's frcm 13 locations surrounding the plant under the olti Tm.Inical Specifications.
Under the new Techn2 cal Specificatione TLD's were analyzed from 23 locations.
Low levels of various radionuclides were observed in the environs of the i
i 1
i
January 1 - December 31, 1985 Docket Nos. 50-317/318 plant during 1985. Some of these observations are attributable to fallout -
from past atmospheric nuclear testing, and some are related to the operation of the plant. With reference to the latter observations: H-3 was observed in a number of bay water samoles from both sampling locations (locations 7 and 8 and sample codes Wai and Wa2): Ag-110m was observed in all oyster samples from the indicator location (location 5 and samole code Ib3) and in two samples from the control location (location 3 and sample code Ib6); Co-60 acoeared in sediment samples with
- concentrations similar to those observed in the past; and Co-58 was observed in a single vegetation sample from a garden on site (sample code Ib4).
In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment. dose calculations were performed using the plant's effluent release data, on site meteorological data, and accrooriate pathways. The results of these dose calculations indicate:
- a. a maximum thyroid dose (via inhalation and garden vegetable pathways) of 0.06 mrem at a location 2400 m south of the plant, which is 0.1% of the acceptable limit of 75 mrem / year as specified in 40 CFR 190 Environmental Radiation Protection ,
Standards for Nuclear Power Operation, and a maximum thyroid dose (via milk pathway) of 0.80 mrem at a location 2700 m SSW of the plant, which is less than 1.2% of the acceptable limit '
of 75 mrem / year (40 CFR 190);
- b. a maximum hhole body gamma dose of 0.01 mrem at a location 800 m soutti of the plant, which is less than 0.1% of the acceptable dose of 25 mrem / year (40 CFR 190);
- c. a maximum whole body dose (via all liquid pathways) of 0.03 mrem, which is less that 0.2% of the acceptable limit of 25 mrem / year (40 CFR 190).
Thus it is concluded, based upon the levels of radioactivity observed and the various dose calculations performed, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1985 did not cause any significant impact on the environment.

January 1 - December 31, 1985 Docket Nos. 50-317/319 l , B. INTRODUCTION i
Baltimore Gas and Electric Company (BG&E) has been conducting a radiological environmental mcnitoring program in the environs of the Calvert Cliffs Nuclear Power Plant since the summer of 1970. The Calvert
. Cliffs site is an operating nuclear generating station consisting of two PWR units. Unit 1 achieved criticality on October 7, 1974 and commenced commercial operation in May 1975. Unit 2 achieved criticality on November 30, 1976 and went into commercial operation April 1.1977.
Originally the radiological environmental monitoring program was conducted under seoarate Environmental Technical Specifications (23,24). On July 29, 1977 the monitoring program began operation under a combined set ' of Technical Specifications (22). The program has operated as such until the early part of 1985 when the Environmental Technical Soecifications were revised to reflect a new generic format for radiological environmental monitoring adopted by the Nuclear Regulatory Commission -(25). Changes in the program (samole locations, sample types, and/or sampling frequencies) i have been imolemented to conform with these revisions.
i
- Results of the monitoring program for the . precoerational and previous operational oeriods through December 31, 1984, have been recorted in a series of documents (1-21).
Results of the monitoring program for the current operational period of January 1,1985 through December 31, 1985 are included in this report. The i report presents the content . of the Radiological Environmental Program
! (Table 1), the samoling locations (Aopendix A), the summary of analytical results of 1985 (Table 2), a compilation of the analytical data for 1985 (Aopendix B), the results of the EPA intercomoarison orogram. (Accendix C), -
and the results of the Land Use Survey (Appendix D). Interpretation of the data and conclusions are presented in the body of this report.
The environmental surveillance data collected during this recorting period
, were comoared with that generated in previous periods whenever possible in order to evaluate the environmental radiological . impact of the coeration of Calvert Cliffs . Nuclear Power Plant Units 1 and 2 during the year 1985.

C. PROGRAM i -
C.1 Objectives f
The objectives of the radiological environmental monitoring program are:
- a. To determine whether any statistically significant increase occurs in the concentration of radionuclides in important pathways,
- b. To detect any measurable buildup of long-lived radionuclides in the environment, 3

January 1 - December 31, 1985 Docket Nos. 50-317/318
- c. To monitor and evaluate ambient radiation levels, -
- d. To verify that radioactivity and ambient radiation levels attribu-table to the plant are within the limits specified in the Technical Specifications (21) and the Environmental Radiation Protection Standards as set forth in 40 CFR Part 192.
C.2 Sample Collection The locations of the individual sampling statiens are listed in Table A-1 and shown in Figure A-2 for the old Technical Specifications and in Table A-2 and Figures A-3 and A-4 for . the new Technical Specifications. Table A-2 also shows the equivalance between the monitoring stations common to both Technical Specifications. All samples were collected by contractors to. or personnel of, Baltimore Gas and Electric Company according to BG&E ooerating procedures (26). Radiochemical analyses were performed by Teledyne Isotooes and BG&E in accordance with established laboratory procedures (27,28).
Ambient radiation measurements were made by BG&E personnel in accordance with BG&E operating procedures (26). These measurements were made with ,
thermoluminescent dosimeters as previously described (10).
The transition from the old program requirements to the new program ,
requirements occurred during the first quarter of 1985. The new Technical Specifications were implemented on March 1, 1985 and the old Technical Specifictions wer;e gradually phased out.. Only those old Technical Scecifications that reouired quarterly compohttes of samples collected throughout the quarter were continued through the first quarter. The new Technical Specifications in these situations were implemented on April 1, 1985.
- 6 C.3 Data Interpretation It is a characteristic of environmental monitoring data that many results occur at or below the minimum detectable level (MDL). In this reoort, all results at or below the- relevant MDL are reported as being . "less than" the MDL value.
C.4 Procram Exceotions .
No i coted aquatic plants were found during 1985.
Samples of vegetation were unavailable from the garden on site (sample codes Ib2 and Ib3) during the month of July.
Milk samples were unavailable before the new Technical Soecifications came into ef fect because the cow went dry.

Docket Nos. 50-317/318
. D. RESULTS AND DISCUSSIONS All environmental samples were either analyzed by Teledyne Isotooe's laboratory procedures (27) or BG&E's laboratory procedures (28). The analytical results for this reporting period are presented in Aopendix B and also summarized in Table 2 on an annual basis. For the ouroose of discussion, the analytical results are divided into four categories --
Aauatic Environment. Atmosoheric Environment, Terrestrial Environment. and External Radiation. The categories are further divided into subcatagories according to samole type (e.g.. Bay Water, Acuatic Organisms. etc. for Acuatic Environment). And finally, due to the major changes in the Environmental Technical Specifications, most of the subcatagories are further divided into those samples pertaining to the old Technical Specifications and those pertaining to the new Technical Specifications.
D.1 Acuatic Environment The aquatic environment surrounding the plant was monitored by analyzing samoles of bay water, aquatic organisms. bottom sediment, and shoreline i sediment. These samples were obtained from various samoling locations on the Chesapeake Bay near the plant.
D.I.a Bav Water Old Technical Soecifications Monthly bay water samples were taken from two locations during the first' quarter of 1985. These locations are the Plant Intake area (location 8).
and the Plant Outfall area (location 7). These samoles were analyzed for H-3. gamma emitters. Sr-89, and Sr-90.
Monthly analyses for H-3 showed dete.ctable concentrations in only two of the samples collected. These detectable concentrations were 1052+/-137 pCi/l observed in the January sample from location 7 and 235+/-132 pCi/1 in the February sample from location 8. Both concentrations are similar to the results observed in both the preoperational (6) and previous operational periods (7-21)
Monthly analyses for gamma emitters exhibited no detectable concentrations of any fission or activation products in these samolas.
~
Quarterly analyses for radiostrontium exhibited no detectable concerntrations of these nuclides in either of the composited samples.
New Technical Specifications Monthly bav water samples were taken from two locations during the second. third, and fourth quarters of 1985. The locations are Intake ;

locations are identical to those in the old Technical Specifications, the methods of acquiring the samples differs considerably. Under the old j Technical Specifications the samples were " grab samoles". Under the new ;
Technical Specifications the samples were obtained from a continuous samoling system operating for the whole sampling period. These samples were analyzed for H-3 and gamma emitters.
Monthly analyses for H-3 showed two detectable concentrations out of nine samoles taken from the Intake and six detectable concentrations out of nine from the Discharge. The H-3 ranged from 215+/-125 to 277+/- 130 pCi/l for the Intake and from 125+/-89 to 813+/-122 oCi/l for the Discharge. Both ranges are similar to the ranges exhibited for the resoective sampling locations under the old Technical Soecifications (7-21).
The only dissimilarity between the pattern of H-3 results under the old and new Technical Soecifications noted was the larger number of detectable concentrations of H-3 observed at the Discharge (Wa2) as coposed to those usually observed at Plant Outfall (location 7). This dissimilarity may be accounted for if one considers that a continuous sampling system will probably register more positive results than a system relving on a
" grab samole", which may or may not have been taken during a scheduled '
release of radioactive effluent from the plant.
D.1.b Aquatic Organisms New Technical Specifications Samoles of aquatic organisms were taken from four locations during the year 1985. Fish samples were taken, once when in season, from the Intake (samole code Ia1 and Ia2) and from the Patuxent River (samole code Ia4 and Ia5). Oyster samples were taken quarterly from Camp Conoy (sample code Ia3) and Kenwood Beach (samole code Ia6). Edible portions of these samples were analvred for gamma emitters.
Gamma Spectrometric analyses of the fish samples from both locations showed only a single detectable concentration of Cs-137 of 20+/-9 pCi/kg.
This result is similar to the results observed in both the preoperational (6) and prior operational periods (7-21).
Quarterly analyses for gamma emitters in shellfish samples exhibited detectable concentrations of radionuclides in all the oyster samples from .
Camo Conov and in only three of the samples from Kenwood Beach.
Silver-110m, ranging from 73+/-11 to 169+/-17 pCi/kg, was observed in all samples from Camo Conoy, and it was observed in the first and second , i quarter samoles from Kenwood Beach at a concentration of 12+/-7 and 10+/-6 oCi/kg respectively. Cesium-137 was also observed, but only in the third cuarter samples from both locations. The Cs-137 concentrations were 30 +/-8 pCi/kg for the sample from Camp Conoy and 18+/-10 pCi/kg for the 12
January 1 - December 31, 1985 Docket Nos. 50-317/318
. sample from Kenwood Beach. Since the sampling locations are the same as those of the old Technical Specifications, the results can be compared to the results of previous years. In doing so, it is obvious that the concentration levels of Ag-110m are similar to the levels observed in prior years (15-21) and the presence is plant related. For the Cs-137. on the other hand, this marks the first time that this radionuclide has been observed in oysters. Since the Cs-137 can have at least two sources of origin (i.e. past nucles. weaoons testing and the plant itself). it would be very difficult to say with certainty where the observed cesium came from.
The fact that it showed up in the samole 4 rom Kenwood Beach. the control l location, at a level commensurate with that observed in samoles from Camp
, Conoy, the indicator location, strengthens the argument that it is related to cast atmosoheric nuclear testing. Succorting this is the fact . that there was no evidence of Ag-110m found in the samole from Kenwood Beach as one would expect had the plant's effluents washed over both this location and Camo Conoy. Regardless of the actual source of Cs-137, the concentration levels observed are very low and are very close to the LLD's for this radionuclide in shellfish.
! D.1.C Sediment Old Technical Soecifications i
Quarterly sediment samoles were taken from four locations during the first quarter of 1985. The locations are Camp Conoy (location 5),. Long Beach (location 6). Plant Intake area (location 8), and Plant Outfall area (location 7). These samples were analyzed for gamma emitters and Sr-89 and Sr-90.
i Quarterly analyses for gamma emitters in these samples revealed the i
presence of Cs-137, ranging from 180+/-48 to 1085+/-106 pCi/kg in all samples from all locations, and Co-60, ranging from 175+/-96 to 508+/-124 pCi/kg in most of the samples from all locations. The range of Cs-137 concentrations exhibited is similar to the ranges obgerved in the preocerational (6) and prior operational periods (7-21) and is orobably related to past atmospheric nuclear weapons testing. On the other hand, Co-60 is among the activation and fission by-products released fro'n the olant in routine radioactive discharges. Its range of concentrations is similar to those observed in crevious operational oeriods (7-21).

D.2 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters, silver zeolite cartridges, and precipitation samples. These samoles were collected from various locations surrounding the plant.
I D.2.a Air Particulate Filters I Old Technical Specifications Weekly composite air filters samples were collected from seven locations during the first ouarter of 1985. The locations are On Site (location 17),
On Site (location 18), Knotty Pine (location 19), Lusby (location 20), Long Beach (location 21), Cove Point (location 22), and Taylors Island (location l 23). These samoles were analyzed for beta activity, gamma emitters,
+
Sr-89, and Sr-90.
Weekly analyses for beta activity on air particulate filters revealed that ~
the range of data for each location observed during the first quarter of 1985 was less than the ranges of data for the same locations - during the same time frame in 1984 (21). This pattern continues a downward trend of fallout activity noticed in recent years (20,21).
Gamma spectrometric analyses ok monthly composites of these samples
, showed no measureable concentrations of any fission or activation by-products.

Radiostrontium analyses of air particulate filters taken during the first quarter exhibited no detectable concentration of either Sr-89 or Sr-90 in any of these composited samples.
New Technical Specifications
! Weekly composite air filter samples were collected ' from five locations during the second, third, and fourth quarters of 1985. The locations are On Site (samole code A1), Camo Conoy Road (sample code A2), Bey Breeze i Road (sample code A3), Lusby (samole code A4), and the EOF (sample code A5). These samples were analyzed for beta activity and gamma emitters. .
l Weekly bets analyses revealed that although the air particulate sampling locations of the new Technical Specifications are considerably different .
than those of the old Technical Saecifications, the ranges of beta activity observed at the new locations were very similar to the ranges of beta activity found at the old locations (21). This similarity probably reflects a regional effect of natural radiation and a ubiquitous fallout i

Camo Conoy Road (sample code A2), Bay Breeze Road (sample code A3), Lusby (sample code A4), and the EOF (samole code A5).
Radiciodine analyses performed on the samples from all locations exhibited no detectable concentrations of I-131.'
D.2.c Precioitation Old Technical Soecifications Monthly composite precipitation samples were collected from one site, On Site (location IS). and only during the first quarter of 1985. These samoles were analyzed for gross beta, H-3, gamma emitters, Sr-89. and Sr-90.
Monthly analyses for beta activity in precipitation samoles revealed that the range of data for this location is similar to the ranges observed in recent years (13-20).

D.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation, soil. and well water. These samples were collected from various sampling locations near the plant.
D.3.a Veoetation New Technical Specifications Vegetation samples were collected from three locations during the year 1985. The locations are Bay Breeze Road (sample code Ib1 to Ib3), On Site (samole code Ib4 to Ib6), and the EOF (sample code Ib7 to Ib9). These samples were analyzed for gamma emitters.
Gamma spectrometric analyses of these samoles revealed the presence of Co-58 in one sample, the December mustard sample Ib4 taken from near the Camo Conoy entrance. The concentration of this radionuclide was 43+/-23 pCi/kg. Cesium-137 was also observed in a number of samples taken from all ~
sites, ranging from 35+/-20 to 194+/-32. These Cs-137 results are similar to those oserved in other vegetation samoles taken from farms near the plant during previous operational periods (7-21) and are probably the
~
result of fallout from past nuclear weapons testing. No evidence of I-131 was observed in any of the samples.
D.3.b Soil !
Old Technical Specifications Soil samples were taken from three on site locations during the first quarter of 1985. The locations are 11, 12, and 13. These samoles were analyzed for gamma emitters, Sr-89 and Sr-90.
Gamma spectrometric analyses revealed the presence of Cs-137 in two of the three samples collected. The concentrations were 302+/-48 pCi/kg for the sample from location 11 and 488+/-66 pCi/kg for the sample from location 13. The results are similar to those observed in the preoperational (6) and prev 1cus coerational oeriods (7-21) and are probably due to the depositien of fallout from past nuclear weapons testing. .
Radiostrontium analyses of the soi) samoles showed no detectable concentrations of Sr-89, and only a single detectable concentrations of .
Sr-90 in the March samples from locations 11 of 22+/-9 pCi/kg. This Sr-90 result is similar to the results observed in both the oreccerational (6) and previous operational (7-21) periods and is probably related to fallout from past nuclear testing.

These locations are the Chesapeake Country Club (location 2), On Site (location 10), Long Beach (location 21), and White Sands Club (locations 25A and 25B). These samples were , analyzed for H-3 and gamma emitters.
Analyses for H-3 and gamma emitters in these samples showed no measureable concentrations of any fission or activation by-products.
D.4 External Radiation Old Technical Specifications Thermoluminescent dosimeters were collected monthly from 13 locations surrounding the olant during the first quarter of 1985. These locations are the Plant Outfall (location 7a), On Site (location 17), On Site (location 18), Knotty Pine (location 19),' Lusby (location 20), Long Beach (location 2D.
Cove Point (location 22), Taylors Island (location 23). On Site (location 24).
White Sands Club Sign (location 25), S t. Leonard (location 26), Solomons Island (location 27), and Bertha Church (location 28). The dosimeters were read for external radiation exposure in milliroentgen (mR).
The TLD data during this period 5Dr all locations comoared very closelv to the corresponding data observed lfor the same locations in recent years (15-21). These data are well within the ranges of values observed for each location in previous years and in many cases less than the mean value observed at each location.
New Technical Soecifications TLD's were collected monthly from 23 locations surrounding the plant. The locations are On Site (sample code DR1), Route 4 (sample code DR2).
Giovanni's Tavern (sample code DR3), White Sands (sample code DR4). John's Creek (sample code DR5). Lusby (sample code DR6), On Site (samole code DR'). On Sita (sample code DR8). Bay Breeze Road (sacole code DR9), S t.

Although there exists no historical data for most of these new locations 17
I January 1 - December 31, 1985 Docket Nos. 50-317/318 to comoare the current data with, the means and ranges observed at all -
locations are very similar to those means and ranges observed at the locations of the old Technical Specifications (15-21). This general trend is to be expected, as the regional ambient radiation levels should be similar.
E. CONCLUSION Low levels of various radionuclides were observed in the environment surrounding the plant during 1985. Most of these observations were attributed to the fallout from atmosoheric nuclear weapons testing, and others were related to the operation of the plant (viz. H-3 in bay water; Ag-110m in shellfish samoles; Co-60 in sediment samples; and Co-58 in a vegetation sample).
In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calculations were performed using the plant's effluent release data, on site meteorological data. and appropriate pathways. The results of these dose calculations indicate:
- a. a maximum thyroid dose (via inhalation and garden vegetable pathways) of 0.06 mrem at a location 2400 m south of the ,
plant, which is 0.1% of the acceptable limit of 75 mrem / year as specified in 40 CFR 190 Environmental Radiation Protection Standards for Nuclear Power Operations, and a maximum thyroid ,
dose (via milk pathway) of 0.80 mrem at a location 2700 m SSW of the plant, which is less than 1.2% of the acceptable limit of 75 mrem / year (40 CFR 190); ,
- b. a maximum whole body gamma dose of 0.01 mrem at a locaticn 800 m south of the plant, which is less that 0.1% of the acceptable dose of 25 mrem / year (40 CFR 190);
- c. a maximum whole body dose (via all liquid pathways) of 0.03 mrem, which is less than 0.2% of the acceptable limit of 25 mrem / year (40 CFR 190).
Thus it is concluded, based upon the levels of radioactivity observed and thc- various d6se calculations performed, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1985 did not cause any significant imDact on the environment.

3.4 3.4 Discussion A Land Use Survey was conducted during the growing season of the year 1985 to identify, within a distance of 8 km. the location of the nearest milk animal, the nearest residence. and the nearest garden e greater than 50 m2 in each of the nine sectors over land. A detailed description of the Land Use Survey is given in a separate document (32). The position of the nearest dairy cows, residence. and garden in each sector up to 8 km are given in the above table.
The closest residence and garden are situated in the WSW sector, which is one of the least prevalent wind direction 9 In the S, SSE, and SE sectors there is the highest probability of Qind blowing from the direction of the plant. One sampling garded is located in the S sector at a distance of 0.8 km, and another is situated near the site boundary between the SSE and SE sectors at a distance of 2.6 km from the plant. These two sampling sites are considered good indicator locations for radioactive depositions around the plant. There are no sites identified in the Land Use Survey that show a greater dose commitment than those sites currenty being sampled. The dose assessment using 1985 meteorological data was performed, and no significant impact from the plant operation was found.
