SUMMARY
During the first quarter of 1985 the Environmental Technical Soecifications for Calvert Cliffs Nuclear Power Plant Units 1 and 2 were changed substantially. Under these Technical Soecifications samples were still 1
taken from the aquatic, atmospheric, and terrestrial environments with the emchasis on critical pathways. In many cases, however, sample locations, samole types, and/or sampling frequencies were changed censiderably from that found in the previous Environmental Technical Soecifications.
A total of 780 analyses were performed on 651 environmental samoles 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.
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 emitting nuclides. Fish bones and sediment were also to be analvmed for Sr-89 and Sr-90. Under tne new Technical Specifications bay water was analvred 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
. arecipitation. Air carticulates and gaseous iodine were collected .on glass fiber filters and silver zeolite molecular sieve cartridges, resoectivelv.
Under the old Technical Soecifications the particulate filters were analvred 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 cuarterly composited air oarticulate filters.
Precioitation was analyzed for gross beta, H-3. Sr-89. Sr-90, and gamma-emitting nuclides. Under the new Technical Soecifications the particulate filters were analvred for beta activity and gamma emitting nuclides. The molecular sieve cartridges were analv:ed for airborne I-131.
Under the old Technical Soecifications, samples from the terrestrial environment included milk, vegetation, soil, and ground water samples. Milk samoles were to be analyzed for gamma emitters, I-131. Sr-89, and Sr-90.
The vegetation and soil samoles were to be analyzed fcr gamma emitters, Sr-89, and Sr-90. The ground water samoles were analyzed for H-3 and l gamma emitters. Urder the new Technical Soecifications only vegetation I
samoles were collected and analyzed for gamma emitters and I-131.
Measuremer.ts of external radiation were performed by analyzing TLD's from 13 locations surrounding the plant under the old Technical Specifications.
Under the new Technical Specifications TLD's were analyzed from 23 locations.
Low levels of various radionuclides were observed in the environs of the 1
. - . ,._ j i
l l
l 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 nur.her of bay water samoles from both samoling locations (locations 7 and B and sample codes Wal and Wa2): Ag-110m was observed in all oyster samples from the indicator location (location 5 and samole code Ib3) and in two samoles 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 vegetatic'n sample from a garden on site (samole code Ib4).
In order to assess the plant's contribution to the ambient radiation levels of the sorrounding environment, dose calculations were performed using the plant's effluent release data. .on site meteorological data. and accroorlate oathways. The results of these dose calculations indicate:
- a. a maximum thyroid dose (via inhalation and garden vegetabl.e ,
pathways) of 0.06 mrem at a location 2400 m south of the plant, which is 0.1% of the acceptacle limit of 75 mrem / year as specified in 40 CFR 190 Environmental Radiation Protection Standards for Nuclear Power Operation, and a maximum th-oid -
dose (via milk pathway) of 0.80 mrem at a location 27GO 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 location 800 m south of the plant,!which is less than 0.1% of the acceotable 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 acceotable limit of 25 mrem / year (40 CFR 190).
Thus it is concluded, based uoan 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 imoact on the environment.

. B. INTRODUCTION
!- 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 ccmmenced i commercial coeration 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 j under seoarate Environmental Technical Specifications (23,24). On July 29,-
1977 the monitoring program began operation under a combined set of
- Technical Soecifications (22)._ The program has coerated as such until the f 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) have been -imolemented to conform with these revisions.
]
Results of the monitoring program for the orecoerational and. previous i . operational periods through December 31, 1984, have ' been recorted in' a series of documents (1-21).
, . Results of the monitoring program for the current ocerational period of
-January 1,1985 through December 31, 1985 are included in this report. The
~
reoort 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 4
(Appendix 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 reocrt.
The environmental surveillance data collected- during this recorting period were comoared with that generated in previous periods whenever possible i in order to evaluate the environmental radiological impact of the i i operation of Calvert Cliffs Nuclear Power , Plant Units 1 and 2 during the j year 1985.

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

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-i 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.
I C.2 Sample Collection
!- The locations of the individual sampling stations are listed in_ Table A-1 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 j both Technical - Specifications. All- samples were collected by contractors t to, or personnel.' of. Baltimore Gas and Electric Comoany according to SG&E
! operating procedures (26). Radiochemical analyses were performed by l Teledyne Isotopes land BG&E in accordance with established laboratory i procedures (27,28).
! Ambient radiation measurements were made 'by BG&E personnel in accordance l with BG&E operating procedures (26). These measurements were made with t
thermoluminescent dosimeters as previously-described (10). -
The transition from .the cid program' requirements to the new program .
requirements occurred during the first quarter of 1985. The new Technical -
Specificaticns were implemented on March 1, 1985 and the old Technical Spec 1 fictions were gradually phased out. 3 Only those old Technical l Scecifications that required- quarterly compotites of samoles collected j throughout the ottarter were continued through the first quarter. The new
- Technical Specifications in these situations were implemented on April 1, I 1985.
J C.3 ~ Data Interoretation l It. is a characteristic of environmental monitoring data that many results j occur at or below the minimum detectable level (MDL). In this report, all
! .results at or below the relevant MDL are reported as being "les s than" j the MDL' value.
i l
C.4 Program Excections 1
No rooted aquatic plants were found during 1985.
[ ..
\ Samples of vegetation were unavailable from the garden on site _ (sample i codes Ib2 and Ib3) during the month of July. . l l
I Milk samples were unavailable before the new Technical Soecifications came i into effect because the cow went dry.

. D. RESULTS AND DISCUSSIONS All environmental samples were either analyzed by Teledyne Isotooe's laboratory orocedures (27) or BG&E's laboratory procedures (28). The analytical results for this reporting period are presented in Appendix B and also summarized in Table 2 on an annual basis. For the ourcose of discussion, the analvtical results are divided into four categories --
Aquatic Environment. Atmosoheric Environment, Terrestrial Environment. and External Radiation. The categories are further divided into subcatagories according to samole type (e.g.. Bay Water, Aouatic Organisms. etc. for Acuatic Environment). And finally, due to the ma jor 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 Aouatic Environment The aquatic environment surrounding the plant was monitored by analyzing samoles of bay water, aquatic organisms, bottom sediment. and shoreline sediment. These samples were obtained from various sampling locations on the Chesapeake Bay near the plant.
D.l.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), i and the Plant Outfall area (location 7). These samoles were analyzed for H-3. gamma emitters, Sr-89, and Sr-90.
1 Monthly analyses for H-3 showed detectable concentrations in only two of the samples collected. These detectable concentrations were 1052+/-137 pCi/l observed in the Januarv sample from location 7 and 235+/-132 oCi/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 detects.ble concentrations of any fission or activation products in these samoles.
Quarterly analyses for radiostrontium exhibited no detectable concentrations of these nuclides in either of the composited samoles.
New Technical Specifications Monthly bay water samples were taken from two locations during the second, third, and fourth quarters of 1985. The locations are Intake 11
)
January 1 - December 31. 1985 Docket Nos. 50-317/318 (samole code Wal) and Discharge (sample code Wa2). Though these samoling -
locations are identical to those in the old Technical Specifications, the methods of acquiring the samples differs ~ considerably. Under the old Technical Specifications the samples were " grab samples". .Under the new Technical Specifications the samoles were obtained from a continuous samoling system operating for the whole samoling period. These samples were analyzed for H-3 and gamma emitters.
Monthly analyses for H-3 showed two detectable concentrations out of nine samples 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 pCi/1 for the Discharge. Both ranges are similar to the ranges exhibited for the respective sampling locations under the old Technical Specifications (7-21).
The only dissimilarity between the pattern of H-3 results under the old and new Technical Specifications 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 orobably register more positive results than a system relving on 'a 1 " grab sample", 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 1 !
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 (sample 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 analvzed for gamma emitters.
Gamma Spectrometric analyses of the fish samoles 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 samoles from Camo Conoy and in only three of the samoles 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 ,
quarter samoles from - Kenwood Beach at a concentration of 12+/-7 and l
- 10+/-6 oCi/kg respectively. Cesium-137 was also observed, but only in the ,
third ouarter samples from both locations. The Cs-137 concentrations were j 30 +/-8 pCi/kg for the sample from Camp Conoy and 18+/-10 pCi/kg for the 12 i

.. sample from Kenwood Beach.. Since the sampling locations are the same as those of the old Technical Specifications, the results can be. comoared 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 i 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 j origin (i.e., past nuclear. weacons. testing and the plant itself). it woul 2 be very difficult to 'say with certainty where the observed cesium came from..
The . fact that it showed un in the samole from Kenwood Beach. the control location. at a level commensurate. with that observed -in samples from Camp Conoy, the indicator location, strengthens the argument that it is related to past atmosoheric nuclear testing. Supporting 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 Camp Conov. Regardless of the actual source of Cs-137, the
- concentration levels observed are very low' and are very close to the l LLD's for this radionuclide in shellfish.
t D.1.c Sediment
- - . Old Technical Soecifications Quarterly sediment samples were taken from four locations during the
. first quarter of 1985. The locations are Camp Conov (location 5), Long 1 Beach (location 6). Plant Intake area (location 8), .and Plant- Outfall area
, (location 7). These samples were analyzed for gamma emitters and Sr '
and Sr-90.
Quarterly analyses for gamma emitters in these samoles revealed the 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+/-86 to 500+/-124 pCi/kg in most of the samples from all locations.' The range of Cs-137 i
concentrations exhibited is similar to the ranges observed in the
! precoerational (6) and prior operational periods (7-21) and . is probably.
j related to past atmospheric nuclear weapons testing. On the other hand,
! Co-60 is among the activation and fission ,by-products released from the
- olant in routine radioactive discharges. Its range of concentrations is similar to those observed in previous operational oeriods (7-21).
1 Quarterly radiostrontium analyses of the sediment samples exhibited no measureable concentrations of either Sr-89 or Sr-90.

Gamma spectromotric anaylses exhibited no detectable concentrations of -
any fission or activation products in these samples.
D.2 Atmospheric Envircnment 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.
D.2.a Air Particulate Filters Old Technical Specifications Week 1v comoosite air filters samples were ' collected from seven locations during the first cuarter 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 23). These samoles were analyzed for beta activity, gamma emitters, Sr-89, and Sr-90.
Weekly analyses for beta activity on air oarticulate - filters revealeo 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 of monthly composites of these samples showed no measureable concentrations of ariy fission or activation by-products.
Radiostrontium analyses of air particulate . filters taken during the first quarter exhibited no detectable concentration ofi 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), Camp Conoy Road (samole code A2), Bay Breeze Road (sample code A3), Lusby (samole code A4), and the EOF (sample code A5). These samples were analyzed for beta activity and gamma emitters.
Weekly beta analyses revealed that although the air particulate sampling .
locations of the new Technical Specifications are considerably different than those of the old Technical Specifications, the ranges of beta l activity observed at the new locations were very similar to the ranges of .
beta activity found at the old locations (21). This similarity probably 1 reflects a regional effect of natural radiation and a ubiquitous fallout 14

D.3 Ter-estrial Environment The terrestrial environment was monitored by analyzing samples of vegetation, soil, arid well water. These samples were collected from various samoling locations near the plant.
D.3.a Vegetation New Technical Specifications Vegetation samples were collected from three locations during tne year 1985. The locations are Bay Breeze Road (sample code Ib1 to Ib3), On Site (sample 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 Coney entrance. The concentration of this radionuclide was 43+/-23 pCi/kg. Cesium-137 was also diaserved 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 olant 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 previous coerational oeriods (7-21) and are prcbably due to the deposition of fallout from past nuclear weapons testing.
Radiostrontium analyses of the soil 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 creocerational (6) ,
and previous operational (7-21) periods and is orobably related to fallout from past nuclear testing.

The TLD data during this period for all locations comoared very closelv to the corresoonding data observed - for the same locations in recent years G5-21). 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 Specifications TLD's were collected . monthly from 23 locations surrounding the plant. The locations are On Site ; (sample cooe ' DR1), ' Route 4 (sample code DR2).

locations are very similar to those means and ranges observed at the locations of the old Technical Specifications (15-21). 'This general trend is j to be exoected, 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 atmospheric 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 aopropriate pathways. The t esults 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 soecified 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 location 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 the various dose calculations performed, that the coeration of Calvert l
Cliffs Nuclear Power Plant Units 1 and 2 during 1985 did not cause any significant imoact on the envircnment.

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 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 directions. In the S, SSE, and SE sectors there is the highest probability.of wind blowing from the direction of the plant. One sampling ~ garden 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.
