SUMMARY
During the 1998 operating period for Calvert Cliffs Nuclear Power Plant (CCNPP) Units 1 and 2, I radiochemical analyses were performed on environmental samples, and thermoluminescent dosimeters (TLDs) were analyzed for ambient radiation exposure rates. These analyses were l
performed to satisfy the requirements of the CCNPP Off Site Dose Calculation Manual (ODCM), Sections 3/4.12.
For the Independent Spent Fuel Storage Installation (ISFSI), radiochemical analyses were j performed on environmental samples, some of which were in common with the power plant
! program. Additional TLDs, some of which are also in common with the power plant program, were analyzed for ambient radiation exposure rates. These analyses were performed to satisfy the requirements of the ODCM.
In addition, radiochemical analyses were performed on quality assurance samples as part of an l internal and extemal quality assurance program associated with Teledyne Brown Engineering, Environmental Services. Performance evaluation samples obtained from the Analytics Cross-Check Program were also analyzed.
And lastly, analyses were performed on extra environmental samples, and extra TLDs were analyzed for ambient radiation exposure rates. Also, six pressurized ion chambers continuously monitored the environs around the plant for ambient radiation levels. The additional analyses reflect a commitment to maintain historical continuity for samples and sampling pathways discontinued from the program when the Environmental Technical Specifications were changed
} in March 1985 and to satisfy our commitment to the community.
Samples collected from the aquatic environment included bay water, fish, oysters, and shoreline l
i sediment samples. Bay water was analyzed for tritium and gamma emitters. Fish, oysters, and shoreline sediments were analyzed for gamma emitting radionuclides.
Monitoring the atmospheric environment involved sampling the air at various locations sur- 1 rounding CCNPP and the ISFSI. Air particulates and gaseous iodine were collected on glass fiber filters and silver zeolite molecular sieve cartridges, respectively. The particulate filters were analyzed for beta activity and gamma emitting nuclides. The molecular sieve cartridges were analyzed for airbome gaseous radioiodine.
Samples from the terrestrial environment consisted of vegetation and soil samples, collected and analyzed for gamma emitters. Vegetation samples for the CCNPP REMP were also analyzed for I-131.
Measurements of direct radiation, as required by the ODCM, were performed by analyzing TLDs from forty locations surrounding CCNPP and the ISFSI.

i I
January 1 - December 31,1998 Dock t Nos. 50-317/318 Low levels of various man-made fission and activation by-products were observed in the environment surrounding the plant during 1998. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (e.g., H-3 in quarterly composited bay water samples and Ag 110m in oyster samples).
To assess the plant's contribution to the radiation levels of the ambient 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 of 4.51 x 10 mrem via liquid and gaseous pathways, which is < 0.01% of the acceptable limit of 75 mrem /yr as specified in 40 CFR 190;
- b. a maximum whole body dose of 5.33 x 10 mrem via liquid and gaseous pathways, which is < 0.1% 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 3.02 x 10 mrem to the GI-Tract. This dose was about 1% of the allowable limit of 25 mrem /yr as specified in 40 CFR 190.
Thus, it is concluded based upon the levels of radioactivity observed and the various dose calculations performed, that Calvert Cliffs Nuclear Power Plant Units I and 2 and the ISFSI did not cause any significant radiological impact on the surrounding environment during 1998.

January 1 - December 31,1998 Docket Nos. 50-317/318 II. CALVERT CLIFFS NUCLEAR POWER PLANT l
RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM ILA. INTRODUCTION l
Baltimore Gas and Electric Company (BGE) 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 l
pressurized water reactors. Unit I 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 (REMP) was conducted under separate Environmental Technical Specifications (36,37). On July 29,1977 the monitoring
! program began operation under a combined set of Technical Specifications (38) for both Units.
The program has operated as such until March 1,1985 when the Environmental Technical i Specifications were revised to reflect a new generic format for radiological environmental monitoring adopted by the Nuclear Regulatory Commission (39). Changes in the program (sample locations, sample types, and/or sampling frequencies) were implemented to conform to these revisions. In October 1996, the Nuclear Regulatory Conunission approved the rclocation l of these Tecimical Specifications to the ODCM in accordance with Generic Letter 89-01. (49)
Results of the monitoring program for the pre-operational and previous operational periods through December 31,1997 have been reported in a series of documents (1-34).
1 Results of the monitoring program for the current operational period of January 1,1998 through December 31,1998 are included in this report. The report presents the content of the Radiological Environmental Monitoring Program (Table 1), the sampling locations (Appendix A), the summary of the analytical results of 1998 (Table 2), a compilation of the analytical data for 1998 (Appendix B), the results of the Analytics Intercomparison Program and the Quality Assurance Program (Appendix C), the results of the Land Use Surv y (Appendix D), and a compilation of the analytical data for extre samples collected in 1998 (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 !
l that generated in previous periods whenever possible to evaluate the environmental radiological I
impact of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1998. l II.B. PROGRAM II.B.1 Objectives The objectives of the REMP for the Calvert Cliffs Nuclear Power Plant are:
3
January 1 - December 31,1998 Docket Nos. 50-317/318
- a. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits specified in the ODCM (40) and the Environmental Radiation Protection Standards as stated in 40 CFR Part 190,
- b. To detect any measurable buildup oflong lived radionuclides in the environment,
- c. To monitor and evaluate ambient radiation levels,
- d. To determine whether any statistically significant increase occurs in the con-centration of radionuclides in important pathways.
II.B.2 Sample Collection The locations of the individual sampling stations are 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 Calvert Cliffs Nuclear Power Plant Procedures (41).
II.B.3 Data Interpretation Many results in environmental monitoring occur at or below the minimum detectable activity (MDA) In this report, all results at or below the relevant MDA are reported as being "less than" the MD/. value, ll.B.4 Program Exceptions Throughout 1998 oysters were not available at Kenwood Beach which is the designated control location. Control samples were obtained from an alternate location at Hog Island which is located approximately 9 miles SSE of the plant. The program is being modified to reflect this altemate location as the routine control location.
II.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using BGE's laboratory procedures (43). The analytical results for this reporting period are presented in Appendix B and are also summarized in Table 2. For discussion, the analytical results are divided into four categories. The categories are the Aquatic Environment, the Atmospheric Environment, the Terrestrial Environment, and Direct Radiation. These categories are further divided into subcategories according to sample type (e.g., Bay Water, Aquatic Organisms, etc., for the Aquatic Environment).

1 January 1 - December 31,1998 Docket Nos. 50-317/318 II.C.1 Aquatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of bay water, aquatic organisms, and shorelinc sediment. These samples were obtained from various sampling locations on the Chesapeake Bay near the plant.
II.C.I.a Bay Water Monthly bay water samples were taken from two locations during the year. These locations are the Intake Area (sample code Wal) and the Discharge Area (sample code Wa2). The samples were obtained from a composite sampling system operating at each location for the entire i 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 the presence of tritium in the Discharge (Wa2) samples for three of the four quarters, while no detectable readings were observed in the Intake (Wal). The concentrations observed in the discharge ranged from 38*33 to 232*38 pCi/L, which is similar to those ranges observed in ;
previous years, (7-34).
l Figure I compares tritium observed in the plant discharge and intake with annual effluent releases in 1998 as reported in the Radioactive Effluent Release Report required by Technical Specification - Administrative Controls.
Monthly analyses of bay water samples from both locations for gamma emitters exhibited no detectable concentrations of any plant-related radionuclides.
II.C.I.b Aquatic Organisms Samples of aquatic organisms were obtained from four locations during the year. Samples of fish, when in season, are normally collected from the Intake-Discharge Area (sample codes Ia1 and Ia2) and from the Patuxent River (sample codes la4 and Ia5). As shown in Table B-2, two species of fish were sampled at both the plant intake and the control point in the Patuxent River.
Oyster samples were obtained quarterly from Camp Conoy (sample code la3) and Hog Island. As mentioned previously, Hog Island was utilized as a control location in lieu of Kenwood Beach, due to the lack of sample at Kenwood Beach. Edible portion of the fish and oyster samples were analyzed for gamma emitters.
5
January 1 - December 31,1998 Docket Nos. 50-317/318 i
Gamma spectrometric analyses of the fish exhibited no detectable concentrations of any plant-related radionuclides. Oyster samples exhibited low levels of detectable concentrations of the plant-related radionuclide, Ag-110m, in samples obtained from Camp Canoy (Ia3). These concentrations, which ranged from 13*7 to 33*7 pCi/kg, arejust above detectable levels. These concentrations are consistent with the trend in recent years.
II.C.I.c Shoreline Sediment '
Semiannual shoreline sediment samples were taken from one location during the year. This location is Shoreline at Barge Road (sample code Wbl). The samples obtained from this i location were analyzed for gamma emitters.
Gamma spectrometric analyses of these samples exhibited no detectable concentrations of any plant-related radionuclides. '

January 1 - December 31,1998 Docket Nos. 50-317/318 II.C.2 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters and silver zeolite cartridges (for trapping radiciodine species). These samples were collectcd from five locations surrounding the plant. These locations are On Site before the Entrance to Camp Conoy (sample code Al), Camp Conoy Road at the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Route 765 at Lusby (sample code A4), and at the Emergency Operations Facility (sample code A5).
II.C.2.a Air Particulate Filters Weekly composite air particulate filter samples were collected from the five locations during the year. These samples were analyzed for beta activity and gamma emitters.
Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic of background levels (7-34). The values ranged from 0.4x10-2t o 4.0x10-2 pCi/m3 or f the indicator locations and 0.8x10 -2 to 2.9x10 -2 pCi/m3 at the controllo-cation. The location with the highest overall mean of 1.8x10 -2 pCi/m i was A4, Route 765 at Lusby.
Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples.
Figure 3 depicts the historical trends of beta activity.
II.C.2.b AirIodine Weekly composited silver zeolite cartridges (for trapping radioiodine species) were collected ]
from the five locations during the year. These samples were analyzed for radiciodine species. l 4
Weekly radioiodine analyses of silver zeolite cartridges collected from all five locations ex-hibited no detectable concentrations ofI-131.
Figure 3 depicts the historical trends of radioiodine.
II.C.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation collected monthly, when available, from various sampling locations near the plant during the normal growing season.

II.C.4 Direct Radiation Direct radiation is measured by a network of TLDs in each overland sector surrounding the Plant both at the plant boundary and at 4 miles from the Plant.
Thermoluminescent dcsimeters were collected quarterly from twenty-three locations surrounding the plant. The twenty indicator locations are On Site Along the Cliffs (sample code DRI), Route 765 Auto Dump (sample code DR2), Giovanni's Tavern (sample code DR3), Route 765 across from White Sands (sample code DR4), John's Creek (sample code DR5), Lusby (sample code DR6), On Site before the Entrance to Camp Conoy (sample code DR7), On Site at Emergency Siren (sample code DR8), Bay Breeze Road (sample code DR9), Decatur and Calvert Beach Roads (sample code DR10), Dirt Road off Mackall and Parran Roads (sample code DRil),
Mackall and Bowen Roads (sample code DR12), Wallville (sample code DR13), Rodney Point (sample code DR14), Mill Bridge and Tumer 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), and On Site Near Shore (sample code DR20). The three control locations are the Emergency Operations Facility (sample code DR21),
Solomons Island (sample code DR22), and Taylors Island, Carpenters Property (sample code DR23).
The mean 90 day ambient radiation measured at the indicator locations was 11.91 mR and ranged from 8.49 to 16.78 mR as reported in Table 2. The control locations showed a 90 day mean of 12.85 mR with ranges from 8.11 to 17.65 mR. The location with the highest overall mean of 16.09 was DR23, Taylors Island, Carpenters Property, which ranged from 14.61 to 17.65 mR. A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data (7-34) shows no plant-related contribution to the measured direct radiation exposure for 1998. Figure 4 shows the historical comparison of the yearly means of the TLDs on site, at four miles, and at the control locations.

hnuary 1 - December 31,1998 Docket Nos. 50-317/318 II.D. CONCLUSION Low levels of various man-made fission and activation by-products were observed in the enviromnent surrounding the plant during 1998. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (e.g., tritium in quarterly composited bay water samples and Ag-110m in oysters).
Historical trends for tritium in bay water, Ag-110m and K-40 in oyster samples, nuclear fallout in the Calvert Cliffs area, and TLD data are depicted in Figures 1 through 4. As can be seen from these figures, the plant made no significant radiological contributions to the surrounding l environment during 1998.
To assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calculations were performed using the plant's eftluent 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:
Gaseous Pathways ,
A maximum thyroid dose of 2.21 x 10-3 mrem to a child via the plume, ground, vegetable, meat, and inhalation pathways at 1.7 km SW of Calvert Cliffs. This is about < 0.01% of the acceptable limit of 75 mrem / year as specified in 40 CFR 190, " Environmental Radiation Protection Standards for Nuclear Power Operations."
A maximum whole body gamma dose of 4.38 x 10-4 mrem to a child at 1.7 km SW of Calvert Cliffs, which is < 0.01% of the acceptable dose limit of 25 mrem / year as specified in 40 CFR 190.
A maximum dose to any other organ, in this case the skin, of 1.85 x 10-3 mrem at 1.7 km SW of Calvert Cliffs. This is < 0.01% of the acceptable dose limit of 25 mrem / year as specified in 40 CFR 190.
Liquid Pathways A maximum thyroid dose of 2.30 x 10-3 mrem to a teenager for allliquid pathways, which is < 0.01% of the acceptable dose limit of 75 mrem / year as specified in 40 CFR 190.
A maximum whole body dose of 4.89 x 10-3 mrem to a teen via all liquid pathways, which is about 0.02% of the acceptable dose limit of 25 mrem / year as stated in 40 CFR 190.
13 f
January 1 - December 31,1998 Docket Nos. 50-317/318 l
A maximum dose to any organ, in this case the GI-Tract, of 3.02 x 10-1 mrem to i
an adult for all pathways, which is about 1% of the acceptable dose limit of 25 l
mrem / year specified in 40 CFR 190.
Gaseous and Liquid Pathways Combined A maximum thyroid dose of 4.51x10-3 mrem via liquid and gaseous pathways, which is < 0.1% of the acceptable limit of 75 mrem / year specified in 40 CFR 190.
A maximum whole body dose of 5.33x10-3 mrem via liquid and gaseous pathways which is about < 0.1% of the acceptable limit of 25 mrem / year as speci-fled in 40 CFR 190.
l A maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 3.02x10-1 mrem to the GI-Tract. This dose is about 1% 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 4,0 CFR 190. Therefore, it is concluded that the operation of Calvert Cliffs Units 1 & 2 produced radioactivity and ambient radiation levels significantly below the limits of Off-Site Dose Calculation Manual and 40 CFR Part 190. There was no measurable buildup oflong-lived radionuclides in the environment due to Calvert Cliffs. In addition, there was no statistically significant increase in the concentration ofplant-related radionuclides in important pathways.

January 1 - December 31,1998 Docket Nos. 50-317/318 IIL INDEPENDENT SPENT FUEL STORAGE INSTALLATION RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM III.A. INTRODUCTION In August 1990 BGE initiated a program of additional radiological environmental monitoring around the site for the Independent Spent Fuel Storage Facility (ISFSI). The first dry fuel storage canister was loaded into the ISFSI in November of 1993.
Results of the monitoring program for the ISFSI for the current period of January 1,1998 through December 31,1998 are included in this report.
This report presents the content of the ISFSI radiological environmental monitoring program (Table 3), the ISFSI sampling locations (Appendix A), the summary of the analytical results of the period (Table 4), and r. compilation of the analytical data for the period (Appendix B). Inter-pretation of the data and conclusions are presented in the body of the report.
The ISFSI monitoring program is as described in this section of the repon with the exception of the Pressurized Ion Chambers (PICS). Pressurized Ion Chambers, because they duplicate direct surveillance by TLDs and because they experience problems with reliability, were excluded from the Technical Specification portion of the ISFSI REMP (48). Pressurized Ion Chambers' results, however, are given in table E-9 and will continue to be a non-Technical Specification surveillance to satisfy our commitment to the community.
The results for 1998 were compared with that generated during the previous ISFSI pre-operational periods (35) and the current and previous CCNPP REMP periods (7-34). These comparisons demonstrate the consistency of data throughout the CCNPP site, which are very close to the natural background levels for the region. A discussion of these results is given in Section III. C. 3.
IILB. PROGRAM III.B.1 Objectives The objectives of the radiological environmental monitoring program for the ISFSI are:
- a. To satisfy the community concern regarding the impact of the ISFSI on the environment, I
- b. To verify that radioactivity and ambient radiation levels attributable to operation of the ISFSI are within the limits specified in the Environmental Radiation Protection Standards as stated in 40 CFR Part 190,
- c. To detect any measurable buildup oflong-lived radionuclides in the environment i due to the ISFSI, 21
January 1 - December 31,1998 Docket Nos. 50-317/318
- d. To monitor and evaluate ambient radiation levels around the ISFSI,
- e. To determine whether any statistically significant increase occurs in the con-centration of radionuclides near the ISFSI.
i III.B.2 Sample Collection The locations of the individual sampling sites are listed in Table A-2 and shown in Figures A-4 and A-5. All samples were collected by BGE personnel according to Calvert Cliffs Nuclear Power Plant Procedures (41).
III.B.3 Data Interpretation Many results in environmental monitoring cccur at or below the minimum detectable activity (MDA). In this report, all results at or below the relevant MDA are reported as being "less than" the MDA value.
III.B.4 Program Exceptions During 1998 the monitoring program was conducted in accordance with the ODCM (40) and applicable procedures (41,43). During an intemal Quality Assurance audit it was noted that the Safety Analysis Report (SAR) for the ISFSI had not been updated to reflect a quarterly TLD reading frequency. A safety analysis was performed in accordance with 10CFR72.48. The results reaffirmed the acceptability of the quarterly frequency. The SAR is being updated.
III.C. RESULTS AND DISCUSSIONS All the environmental samples collected during the year were analyzed using BGE's laboratory procedures (43). The analytical results for this reporting period are presented in Appendix B and are also summarized for the period in Table 4. For discussion, the analytical results are divided into three categories. The categories are the Atmospheric Environment, the Terrestrial Environment, and Direct Radiation. These categories are further divided into subcategories according to sample type (e.g., Vegetation and Soil for Terrestrial Environment).
III.C.1 Atmospheric Environment The atmospheric environment was monitored by analyzing air particulate filters. These samples were collected from five locations surrounding the ISFSI.
No source of airbome radioiodine exists for the ISFSI. Airbome radioiodine is, therefore, not considered.
Ill.C.I.a Air Particulate Filters Weekly composite air particulate filter samples were collected from five locations during the period. These locations are On Site before the Entrance to Camp Conoy (sample code Al; in common with the CCNPP REMP), Meteorological Station (SFA1), CCNPP Visitor's Center 22 l l
l January 1 - December 31,1998
. Dockst Nos. 50-317/318 (SFA2), NNW of the ISFSI (SFA3), and South of the ISFSI (SFA4). These samples were an-alyzed for beta radioactivity and gamma emitting radionuclides.
Weekly analyses for beta activity on air particulate filters collected from all five locations showed values characteristic oflevels routinely observed in the REMP (7-34). These values ranged from 0.4x10-2to 3.7x10-2 pCi/m3 or f the indicator locations and 0.5x10-2t o 3.4x10-2 pCi/m3 for the control location. The location with the highest overall mean of 1.7x10-2 pCi/m3 was SFAI at the Meteorlogical Station.
Gamma spectrometric analyses of monthly composited air particulate samples exhibited no detectable concentrations of any plant-related radionuclides in any of these samples.
III.C.2 TerrestrialEnvironment The terrestrial environment was monitored by analyzing samples of vegetation and soil collected quarterly from the vicinity of the air sampling locations for the ISFSI.
III.C.2.a Vegetation Vegetation samples were collected quarterly from five locations during the year. These locations are: Meteorological Station (sample code SFbl), CCNPP Visitor's Center (sample code SFb2),
NNW of the ISFSI (sample code SFb3), South of the ISFSI (sample code SFb4), and On Site before the Entrance to Camp Conoy (sample code SFb5). These samples were analyzed for gamma emitters.
Gamma spectrometric analyses of these samples revealed the presence of Cs-137 in one sample.
The Cs-137 concentration observed was 117*28 pCi/kg. While the presence of Cs-137 in this sample may be plant-related, this result is consistent with that found to be due to the residual fallout frori past atmospheric nuclear weapons testing. This activity is well below the federal limits estr.olished in 40 CFR 190, " Environmental Radiation Protection Standards for Nuclear Power Operations" and are comparable to those observed in previous annual reporting periods for the CCNPP REMP (7-34) and in the earlier pre-operational data for the ISFSI (35).
III.C.2.b Soils Soil samples were collected quarterly from five locations surrounding the ISFSI in the vicinity of the air samplers. These locations are: Meteorological Station (sample code SFS1), CCNPP Visitor's Center (sample code SFS2), NNW of the ISFSI (sample code SFS3), South of the ISFSI (sample code SFS4), and On Site before the Entrance to Camp Conoy (sample code SFSS).
Soil samples were analyzed for gamma emitting radionuclides. Cesium-137 was detected in quarterly samples from four sites. The Cs-137 concentrations ranged from 26 11 to 1298t104 pCi/kg. While the presence of Cs-137 in these samples may be plant-related, this range is consistent with that found to be due to the residual fallout from 1;ast atmospheric nuclear weapons testing. The activities of this radionuclide are well below the federal limits established in 40 CFR 190," Environmental Radiation Protection Standards for Nuclear Power Operations" l

January 1 - December 31,1998 Docket Nos. 50-317/318 and are comparable to those observed in previous annual reporting periods for the CCNPP REMP (7-34) and in the earlier pre-operational data for the ISFSI (35).
III.C.3 Direct Radiation Direct radiation is measured by a network of TLDs surrounding the ISFSI. These thermo-luminescent dosimeters are collected quarterly from seventeen locations surrounding the ISFSI, plus one control TLD location at the Visitor's Center (sample code SFDR7). The locations include On Site before the Entrance to Camp Conoy (sample code DR7, common to both the CCNPP Program and the ISFSI Program) and the Meteorological Station (sample code DR30, I previously a location maintained for historical continuity.) The other sampling locations are:
SW ofISFSI, Collocated with Plant TLD #159, (sample code SFDRI); N ofISFSI, Collocated with Plant TLD #160, (sample code SFDR2); NNE ofISFSI, Collocated with Plant TLD #161, (sample code SFDR3); NE ofISFSI, Collocated with Plant TLD #162, (sample code SFDR4);
E ofISFSI, Collocated with Plant TLD #163, (sample code SFDRS); ESE ofISFSI, Collocated with Plant TLD #164, (sample code SFDR6); North Northwest ofISFSI,(sample code SFDR8);
South ofISFSI, (sample code SFDR9); NNW ofISFSI, (sample code SFDR10); WNW ofISFSI, (sample code SFDR11); West ofISFSI, (sample code SFDR12); SSW ofISFSI, (sample code SFDR13); SSE ofISFSI, (sample code SFDR14); ENE ofISFSI, (sample code SFDR15); and WSW ofISFSI, (sample code SFDR16). Sampling locations are shown on Figures A-4 and A-5.
The mean 90 day ambient radiation measured at the ISFSI indicator locations was 18.55 mR and ranged from 9.08 to 48.48 mR as reported in Table 4. The control location showed a 90 day mean of 13.67 mR and ranged from 11.58 to 15.83 mR. A comparison of the mean and ranges of the current TLD data with those of both the historical data and the regional data (7 - 35) reveals only one set of elevated TLD readings.
That location with the highest overall mean of 44.42 mR with a range of 38.90 to 48.48 mR was SFDR10, North Northwest ofISFSI. These readings are consistent with those expected from the storage of spent fuel in the ISFSI (7 - 35). A comparison of the mean ISFSI TLD data with the ISFSI control location at the Visitor's Center, SFDR7, can be seen in Figure 7.

January 1 - December 31c 1998 Docket Nos. 50-317/318 III.D. CONCLUSION Low levels of Cs-137 were observed in the environment surrounding the ISFSI during the period.
The Cs-137 observations were attributed to fallout from past atmospheric weapons testing.
In general, the results in the following tables continue the historical trends previously observed at the official sites of the Calvert Cliffs Nuclear Power Plant Radiological Environmental Monitoring Program (7-34).

January 1 - December 31,1998 Docket Nos. 50-317/318 APPENDIX C Appendix C is a summary of BGE laboratory's quality assurance program. It consists of Table C-1 which is a compilation of the results of the laboratory's participation in the Analytics i Radiological Environmental Cross-Check Program during the period January 1,1998 to I December 31,1998. It also consists of Table C-2 and Table C-3 that together form a compilation of the results of the laboratory's participation in a quality assurance program with Teledyne Brown Engineering's Environmental Services during the same period. The Teledyne Brown Engineering operating procedures pertinent to these analyses are described in Reference 42.
All the BGE results contained in Table C-1, with the exception of the tritium cross check on 9/24/98, agree with Analytics' results within the 3 sigma acceptability criteria. Reanalysis of the Analytics cross check sample by BGE (3165
- 91 pCi/l) and an outside laboratory (3292 200 pCi/l) resulted in agreement.
All the results contained in Table C-2 agree with the laboratory replicates and split samples submitted to Teledyne Brown Engineering, where appropriate. Although there was a split analysis result for Cs-137 in vegetation on 8/27/98 at location Ib6, it was below the BGE laboratory's LLD. Samples whose nature precludes splitting them with Teledyne Brown Engineering are marked "**"in the Split Analysis column.

Appcndix D contains the results of a Land Use Survey conducted around Calvert Cliffs Nuclear Power Plant during June 1998. A table listing the raw data of this survey and a discussion of the results are included in this i
appendix.
Discussion Table D-1 A Land Use Survey was conducted during June Land Use Smey 1998 to identify, vrithin a distance of 8 km, the
, Distance From Plant location of the neuest milk animal, the nearest
- residence, and the nearest garden greater than 50 (g
Sector Residence Garden m2 in each of the nine sectors over land. A SE 2.7 2.7 detailed description of the Land Use Survey is
, , SSE 2.9 2.9 given in a separate document (47). The position !
S 3.1 3.1 of the nearest residence and garden in each sector !
out to 8 km are given in the adjacent table. N SSW 2.6 2.9 SW 2.1 ! 2.6 dairy animal was found within 8 km in any I WSW 1.9 1.9 direction. There has not been any sigmficant change in the use oflocal lands in the last few W 2.1 1 2.1 years.
WNW 2.6 ! 2.6 NW 2.9 l 2.9 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. The two gardens used for vegetable samples by the Radiological Environmental Monitoring 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 depositica.s around the plant. l The dose assessment using 1998 meteorological data was performed, and no significant impact from the plant was found.

January 1 - December 31,1998 Docket Nos. 50-317/318 APPENDIX E Appendix E is a presentation of the analytical results for additional samples collected in the environs of Calvert Cliffs Nuclear Power Plant during the year 1998. These extra samples are not required by the Off Site Dose Calculation Manual (40). They were collected and analyzed to maintain the historical continuity for samples and sampling pathways discontinued when the Environmental Technical Specifications were changed in March, i 1985. Additionally, they include the Pressuried Ion Chambers added for the Independent Spent Fuel Storage i Installation. l l
Table E-11 shows the direct radiation readings from TLDs placed at the perimeter of the resin storage area located to the west of the ISFSI facility. The TLD values are higher than those in the REMP program due to their proximity to the source of the radiation. However, when the direct radiation readings for the ISFSI and Site Boundary TLDs are reviewed, it is apparent that storage of the spent resin is having no significant, measurable effect on the environs surrounding Calvert Cliffs Nuclear Power Plant.
