SUMMARY
During this operating period for Calvert Cliffs Nuclear Power Plant Units 1 end 2, a total of 678 analyses were performed on 670 environmental samples, and 1103 thermoluminescent dosimeters (TLD's) were analyzed for ambient radiation exposure rates. In addition, 162 analyses were performed on 120 quality assurance samples as part of the Environmental Protection Agency's Cross-Check Program and our internal Quality Assurance Program with Teledyne Isotopes company. And lastly, 620 analyses were per-formed on 608 extra environmental samples; 824 extra TLD's were analyzed for ambient radiation expecure rates; and six pressurized ion chambers continuously monitored the environs around the plant for ambient radiation levels. All of these extra analyses were performed as part of a commitment to maintain historical continunty for samples and sampling pathways discontinued when the Environmental Technical Specifications were changed in March, 1985 and to upgrade the Radiological Environ-mental Monitoring Program related to the construction of the Interim Spent Fuel Storage Facility. .
The samples collected from the aquatic environment included bay water, fish, oysters, and shoreline sediment samples. Bay water was analyzed for tritium and gamma emitters. Fish, oysters, and shoreline sediments were analyzed for gamma emitting radionu-clides.
Monitoring the atmospheric environment involved sampling the air at various locations surrounding the plant. Air particulates and gaseous iodine were collected on glass fiber filters and silver zeolite molecular sieve cartridges, respectively. The particu-late filters were analyzed for beta activity and gamma emitting nuclides. The molecular sieve cartridges were analyzed for airborne I-131.
samples from the terrestrial environment consisted of vegetation samples, which were collected and analyzed for gamma emitters and I-131.
Measurements of external radiation were performed by analyzing TLD's from twenty-three locations surrounding the plant.
Low levels of various man-made fission and activation by-products were observed in the environmhat surrounding the plant during the year 1991. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were 1
January 1 - December 31, 1991 Docket Hos. 50-317/318 related to the operation of the plant (viz., Cs-137 in monthly bay water samples, Ag-110m in oyster samples, and H-3 in a quarterly composited bay water sample).
In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calcula-tions were performed using the plant's effluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicates
- a. a maximum thyroid dose of 0.17 mrom via liquid and gaseous pathways, which is about 0.2% of the acceptable limit of 75 mrom/yr as specified in 40 CFR 190;
- b. a maximum whole body dose of 0.05 mrem via liquid and gaseous pathways, which is about 0.2% of the acceptable limit of 25 mrem /yr as specified in 40 CFR 190;
- c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 0.29 mrem from the GI tract and skin, respectively. This dose was about 1.2% of the allowable limit of 25 mrem /yr as specified in 40 CFR 190.
Thus it is concluded, baned upon the levels of radioactivity observed and the various dose calculations performed, that Calvert Cliffs Nuclear Power Plant Units 1 and 2 did not cause any significant impact on the surrounding environment during tha year 1991.

I January 1 - December 31, 1991 Docket Nos. 50-317/318 B. INTRODUCTION Baltimore Cas and Electric Company (BG&E) has been conducting a radiological environmental monitoring 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 pressurized water reactors. Unit 1 achieved criticality on October 7, 1974 and commenced commercial I 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 separate Environmental Technical Specifications (28,29). On July 29, 1977 the monitoring program began operation under a combined set of Technical Specifications (30). The program has operated as such until March 1, 1985 when the Environmental Technical Specifications were revised to reflect a new generic format for radiological environmental monitoring adopted by the Nuclear Regulatory Commission (31). hanges in the program (sample locations, sample types, and/or sampling frequencies) have been implemented to conforn to these revisions.
Results of the monitcring program for the preoperational and previous operational periods through December 31, 1990 have been reported in a series of documents (1-27).
Results of the monitoring program for the current operational period of January 1, 1991 through December 31, 1991 are included in this report. The report presents the content of the Radiological Environmental Program (Table 1), the sampling locations (Appendix A), the summary of the analytical results of 1991 (Table 2), a compilation of the analytical data for 1991 (Appendix B), the results of the EPA Intercomparison Program and the Quality Assurance Program ( Appendix C) , the results of the Land Use Survey (Appendix D), and a compilation of the analytical data for extra samples collected in 1991 (Appendix E).
Interpretation of the data and conclusions are presented in the body of the report.
The environmental surveillance data collected during this reporting period were compared with that generated in previous periods whenever possible in order to evaluate tha environmental radiological impact of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during the year 1991.
3 1 _ _ _ _______
January 1 - December 31, 1991 Docket Hos. 50-317/318 C. PROGRAM C.1 Qbjpctiven The objectivou of the radiological environmental monitoring program are:
- a. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits specified in the Technical Specifications (31) and the Environmental Radiation Protection Standards as set forth in 40 CFR Part 190,
- b. To detect any measurable buildup of long-lived radio-nuclides in the environment, ,
- c. To monitor and evaluate ambient radiation levels,
- d. To determine whether any statistically significant increase occurs in the concentration of radionuclides in important pathways.
C.2 Samole Collection The locations of the individual sampling stations aro listed in Table A-1 and shown in Figures A-2 and A-3. All samples were collected by contractors to, or personnel of, the Baltimore Gas and Electric Company according to BG&E Operating Procedures (32).
Radiochemical analyses were performed by B9&E in accordance with established laboratory procedures (34).
C.3 Data Interoretati2D It is the characteristic of environmental monitoring data that many results occur at or below the minimum detectable level (MDL). In this re? ort, all results at or below the relevant MDL are reported as benng "less than" the MDL value.
C.4 Proaram Excentions There were no program exceptions during 1991.

January 1 - December 31, 1991 Docket Hos. 50-317/318 D. RESULTS AND DISCUSL w All the environmental samples collected during the year were analyzed using BG&E's laboratory procedures (34). The ana-lytical results for this reporting period are presented in Appendix B and also summarized on an annual basis in Table
- 2. For the purpose of discussion, the analytical results are divided into four categories. The categories are the Aquatic Environment, the Atmospheric Environment, the Ter-restrial Environment, and External Radiation. These cate-gories are further divided into subcategories according to sample ty pe (e.g., Bay Water, Aquatic orginisms, etc. for the AquatLc Environment).
D.1 Acuatic Environment The aquatic enviornment surrounding the plant was monitored by analyzing samples of bay water, aquatic organisms, and shoreline sediment. These samples were obtained from vari-ous sampling locations on the Chesapeake Bay near the plant.
D.1.a Bay Water Monthly bay water namples were taken from two locatior.s during the year. These locations are the Intake Area (sam-ple code Wal) and the Discharge Area (sample code Pn2). The samples were obtained from a composite sampling system op-erating at each location for the entire sampling period.
These samples were analyzed for tritium and gamma emitters.
The tritium analyses, performed on quarterly composites of the monthly bay water samples, showed a single detectable concentration of tritium. The fourth quarter sample from the Discharge Area (Wa2) exhibited a cencentration of 323146 i pci/L. The sample reflects the increase in tritium releases in liquid offluents (Figure 1). The magnitude of this result is very low and is similar to the low values for tritium that have been observed sporadically in this sampling medium during past operating periods (6-27).
Monthly analyses for gamma emitters exhibited detectable concentrations of Cs-137 in two samples. Both samples were callected from_the Discharge Area (Wa2); the first in Febru-ary at a concentration of 2.111.5 pci/L. Although Cs-137 is a fission product more attributable to past nuclear bomb testing, its presence in the Discharge Area may be indica-tive of the plant being the source of the Cs-137 in these samples. Regardless of the source, however, the magnitude of these results is very close to the range of
January 1 - December 31, 1991 Docket Hos. 50-317/318 Minimum Detectable Limits for this radionuclido in this sampling medium (viz., 1.5-2.2 pCi/L Table D-9).
D.1.b Aquatic Organigma Sampics of aquatic organisms were obtained from four locations during the year. Sampics of fish, when in season, were taken from the Intake-Discharge Area (samples code Ia1 and Ia2), and from the patuxent River (sample codes Ia4 and Ia5). Oyster samples were obtained quarterly from Camp Conoy (sample code la3) and Kenwood Beach (sample code Ia6). Edible portions of these samples were analyzed for gamma emitters.
Gamma spectromet.ric analyses of the fish from both locations exhibited no detectable concentration of any fission or activa-tion products.
Quarterly analyses for gamma emitters in oysters, showed detect-able concentrations of a plant-related radionuclide, Ag- 110'.a , in samples obtained from Camp Conoy (Ia3). The observed cont.9ntra-tions ranged from 69112 to 101112 pC1/kg. The presence o; this radionuclide at these concantration levels is typical of that observed in previous operating periods (7-27).
D.1.c Shoreline Sediment Semiannual shoreline sediment samples were taken from one loca-tion during the year. This location is the shoreline at Camp Conoy (sample code Wbi). The-samples obtained from this location were analyzed for gamma emitters.
Gamma spectrometric analyseu of these samples exhibited no detectable concentrations of any fission or activation products.
D.2 AtmosDheric Environment The atmospheric environment was monitored by analyzing air particulate filtors and silver zeolite cartridges (for trapping radioiodine species). These samples were collected from various locations surrounding the plant.
D.2.a Air Particulate Filters
-Weekly composite air particulate filter samples were collected from five locations during the year. These locations are on Site (sample code A1), Camp Conoy Road IM r the Emergency Siren (sample code A2), Bay Breeze Road (sample rode A3), Lusby (sample 6
s
f Janua*y 1 - December 31, 1991 Dockc Nos. 50-317/318 code A4), and at the Emergency of f site Facility (sample code AS) .
These samples were analyzed for beta activity and gamma emit;ters.
Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of background levels (7-27).
Gamma spectrometric analyses of monthly composited air parti-culate samples exhibited no detectable concentrations of any fission or activation products in any of these samples.
D.2.b Air Iodine Weekly conposited silver zeolite cartridges (for trapping radioiodine species) were collected from five locations during the year. These locations are on Site (sample code A1), Camp Conoy Road Hear the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Lusby (sample code A4), and at the Emer-gency offsite Facility (sample code A5). These samples were analyzed for radiciodino species.
Weekly radioiodine analyses of silver zeolite cartridges collect-ed from all five locations exhibited no detectable concentrations of I-131.
D.3 Terrestrial-Environment The terrestrial environment was monitored by analyzing samples of vegetation collected monthly, when available, from various samp-ling locations near the plant.
D.3.a Veaetation Vegetation samples were collected from three locations during the year. These locations are Bay Breeze Road (sample codes Ibl,_
Ib2, and Ib3), on Site Before the Entrance to Camp Conoy (sample codes Ib4, Ib5, and Ib6), and the Emergency Offsite Facility (sample - codes --Ib7, Ib8, and Ib9) .- These samples were analyzed for gamma emitters, including analyses for I-131.
Gamma spectrometric analyses of these samples revealed' the presence of Cs-137 in three vegetation samples collected from the
-gardens surrounding _the plant. The range of concentrations observed was 1419 to 23117 pCi/kg. The presence of this radionuclide in -these samples is probably_ due to .the residual fallout from past-atmospheric nuclear weapons testing.

January 1 - December 31, 1991 Docket Hos. 50-317/318 D.4 gyternal Radiation :
Thermoluminescent dosimeters were collected monthly from twenty-three locations surrounding the plant. The locations are On Site Along the Cliffs (sample code DR1), Route 4 Auto Dump (sample code DR2), Giovanni's Tavern (sample code DR3), Whtte Sands (sample code DR4), John's Creek (sample code DRS), Lusby (sample code DR6), on Site (sample code DR7), On Site Near the Emergency Siren (sample code DRB), Bay Breeze Road (sample code DR9),
Decatur and Calvert Beach Roads (sample code DR10), Dirt Road off Mackall and Parran Roads (sample code DR11), Mackall and Bowen Roads (sample code DR12), Wallville (sample code DR13), Rodney Point (sample code DR14), Mill Bridge and Turner Roads (sample code DR15), Appeal School (sample code DR16), Cove Point and Little Cove Point Roads (sample code DR17), Cove Point (sample code DR18), Long Beach (sample code DR19), On Site Near Shore (sample code DR20), Emergency Offsite Facility (sample- code DR21), Solomons Island (sample code DR22), and Taylors Island (samplo code DR23).
A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data (7,27) shows that no plant-related contribution to the measured exposure rate for 1991 was discernible.
E. Conclusion Low levels of various man-made fission and activation by-products were observed in the environment surrounding the plant during the year 1991. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (viz., Cs-137 in monthly bay water samples, Ag-110m in oyster samples, and tritius in a quarterly composited bay water sample).
Historical tren6a for tritium in bay water, Ag-110m and K-40 in oyster samples, nuclear fallout in the Calvert Cliffs area, and TLD data from selected sites are depicted in Figures 1 through 4.
As can be seen from these figures, the plant made only negligib?.e radiological contributions to the surrounding environment during the year 1991.
In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calcula-tions were performed using the plant's effluent release _ data, on site meteorological data (see X/Q and D/Q values presented in Figures 5 and 6), and appropriate pathways. The results of-these dose calculations indicate:

January 1 - December 31, 1991 Docket Nos. 50-317/318 GI tract. This dose is about 1.2% of the allowable limit of 25 mrem / year as specified in 40 CFR 190.
In all cases, the calculated doses are a small fraction of the applicable limits specified in 40 CFR 190. On this basis it is ,
concluded that the operation of Calvert Cliffs Units 1 and 2 net the criteria of 40 CFR 190 during 1991.
In addition it is also concluded, based upon the levels of radioactivity observed and the various dose calculations per-formed, that Calvert Cliffs Nuclear Power Plant Units 1 and 2 did not cause any significant impact on the environment during year 1991.

January 1 - December 31, 1991
- Docket Nos. 50-317/318 APPENDIX C Appendix C contains Table C-1 which is a compilation of the results of DG&L laboratory's participation in the Environmental Protection Agency's Cross-Check Program during the period January 1, 1991 to December 31, 1991. It also contains Table C-2 and Table C-3 which together form a compilation of the resultc of BG&E laboratory's participation in a Quality Assurance program set up with Teledyne Isotopes Company during the same period. The Teledyne operating procedures are described in reference 33.
As can be readily soon in Tables C-1 and C-2 the laboratory's results agree quite Well with both the EPA cross-Check results and the Quality Assurance results from replicate and split-sample analyses. There are only two instances where the laboratory's results are different from Teledyne's (See Table C-2). The first instance is where Teledyne reports positive Cs-137 results for three vegetation samples (two in samples obtained in August, 1991 and one in a sample obtained in November, 1991), while our labortory reports results less than the Minimum Detectable Limit for this radionuclide in these samples. Teledyne's results range from 12 to 27 pCi/L. Our laboratory's -Lower Limit of Detection for this type of analysis iu 18 pCi/L, and our Miniumum Detectable Limit range is 19 to 29 pCi/L. Thus, in this instance both sets of results may still be in agreement given the magnitude of the values reported. In the second instance, however, there seems to be an actual discrepency between our labortory's results and those of Toledyne's. In the November, 1991 bay water sample from the Intake our laboratory reports tritium - values of 321+/-44 and 181+/-38 pL1/L, while Teledyne reports a value less than their Minimum Detectable Limit of 100 pCJ/L for tritium. Repeat analyses will be performed. 61

E Discussion A Land Use Survey was conducted during the growing season of the year 1991 to identify, within a distance of a km, the location of the nearest milk animal,2 the nearest residence, and the nearest garden greater than 50 m in each of the nine sectors over land. A detailed description of the Land Uso survey is given in a separate document (38). The position of the nearest dairy cow, 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 f rom the direction of the plant. The two gardens used for vegetable samples by the Radiological Environmental Program have been placed in the sectors with the highest X/Q. One sampling garden is located in the S sector at a distance of 0.7 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. The milk cows within a distance of 8 km from the plant are situated in the SSW sector, at 4.8 km from the release point. This sector is closely monitored by two TLD's (DR6 and DR15) and by an air sampler (A4). 75
January 1 - December 31, 1991 Docket Nos. 50-317/318 Consideration was given to the feasibility of performing additional environmental monitoring for the grass-milk pathway. At this location forage samplos were collected and analyzed (seo Table E-6 in Appendix E) . Milk samplos woro not obtainable.

January 1 - December 31, 1991 Docket Hos. 50-317/318 APPENDIX E Appendix E is a presentation of the analytical results for a number of additional samples collected in the environs of Calvert Cliffs Nuclear Power Plant during the year 1991. These extra samples are not required by the Environmental Technical Specifications (28-31). They were collected and analyzed in order to maintain the historical continuity for samples and sampling pathways discontinued when the Environmental Technical Specifications were changed in March, 1985. In addition, this extra sampling is meant to broaden the rango of our current monitoring program in order to begin preoperational monitoring for the proposed Interim Spent Fuel Storage Facility (ISFSP). With these reasons in mind the following samples were added to our monitoring program:
- 1. TLD's were placed at Cambridge, Maryland in February, at two additional sites on Taylors Island in July, and at the Intake area of plant in September to record ambient radiation levels;
- 2. Air samplers to collect air particulates and air iodines were setup at the Visitors Center and Cambridge, Maryland in January and at the Northeast corner of the ISFSF in May;
- 3. Pressurized ion chambers were installed at the Northeast corner of the ISFSF in May, at the Southwest corner of the ISFSF in July, and at Visitors Center in August to record ambient radiation levels;
- 4. Soil samples were taken from various locations around the ISFSF in the third and fouth quarters.
S. Newly fabricated, enhanced air camplers with air particulato filters and silver zeolite cartridges have replacing existing air samplers in the monitoring program. In general, the resulta in the following tables continue the historical trends observed in the past, and in thosa cases where new sampling sites were established, the levels observed are similar to those observed at the official sites of the Environaental Monitoring Program. 77
