1.0 INTRODUCTION
This report summarizes and interprets results of the Radiological Environmental Monitoring Program conducted by Environmental, Inc., Midwest Laboratory at the Duane Arnold Energy Center, Palo, Iowa, during the period January - December, 2007. This Program monitors the levels of radioactivity in the air, terrestrial, and aquatic environments in order to assess the impact of the plant on its surroundings.
Tabulation of the individual analyses made during the year are included in Part II of this report.
The Duane Arnold Energy Center (DAEC) is a boiling water reactor, located in Linn County, Iowa, on the Cedar River, and owned and operated by FPL Energy. Initial criticality was attained on March 23, 1974. The reactor reached 100% power on August 12, 1974. Commercial operation began on February 1, 1975.

SUMMARY
The Radiological Environmental Monitoring Program, as required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Duane Arnold Energy Center, is herein described. Results for the year 2007 are summarized and discussed.
Program findings show background levels of radioactivity in the environmental samples collected in the vicinity of the Duane Arnold Energy Center.
No effect on the environment is indicated in the areas surrounding the site of the Duane Arnold Energy Center.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Procgram Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Duane Arnold Energy Center (DAEC) is to assess the impact of the plant on its environment. For this purpose, samples are collected from the air, terrestrial, and aquatic environments and analyzed for radioactive content.
In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (TLDs).
Sources of environmental radiation include the following:
(1)
Natural background radiation arising from cosmic rays and primordial radionuclides; (2)
Fallout from atmospheric nuclear detonations; (3)
Releases'from nuclear power plants; and (4)
Industrial and medical radioactive waste.
In interpreting the data, effects due to the DAEC operation must be distinguished from those due to other sources.
A major interpretive aid in assessment of these effects is the design of the monitoring program at the DAEC which is based on the indicator-control concept. Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the DAEC site. The DAEC's monitoring program includes analyses for strontium-90 and iodine-131, which are fission products, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants.
Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified: zirconium-95, cesium-137, and cerium-144. These three gamma-emitting isotopes were selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation. Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products ten (10) days after reactor shutdown. On the other hand, ten (10) days after a nuclear explosion, the contributions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963). The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, barium-lanthanum-140, and cerium-141.
These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the next group, manganese-54, cobalt-58 and-60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant effluents, but are not produced in significant quantities by nuclear detonations. Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as calibration monitors and provide a comparison between levels of naturally occurring radionuclides and radionuclides that could be attributed to the operation of the plant.

3.1 Progqram Design and Data Interpretation (continued)
Characteristic properties of isotopes quantified ingamma-spectroscopic analysis are presented in Table 5.1. Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including those measured before the Plant became operational. Results of the DAEC's Monitoring Program can be related to those obtained in other parts of the world; Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.
3.2 Program Description The sampling and analysis schedule for the environmental radiological monitoring program at the DAEC is summarized in Table 5.2 and is briefly reviewed below. Table 5.3 defines the sampling location codes used in Table 5.2 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor site. The types of samples collected at each location and the frequency of collections are presented in Table 5.4 using codes defined in Table 5.5.
To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at eight locations.
Airborne iodine is collected by continuous pumping through charcoal filters. Seven of the eight locations are indicators and one is a control (D-13).
Filters are changed and counted weekly. Particulate filters are analyzed for gross beta activity. If gross beta activity exceeds ten times the yearly mean of the control samples, gamma isotopic analysis is performed.
Quarterly composites of airborne particulates from each location are analyzed for gamma emitting isotopes.
Charcoal filter samples are analyzed weekly for iodine-1 31.
Ambient gamma radiation is monitored at a total of 46 locations. A TLD is placed at each location and is exchanged and analyzed quarterly. The TLD locations are distributed as follows:
Eight at active air sampling stations.
Four at de-activated air sampling stations greater than 3 miles from the DAEC stack.
Eighteen in a circle within a 0.5 mi. radius from the DAEC stack.
Six in 22.50 sectors within 1 mi. from the DAEC stack.
Ten in 22.5' sectors between 1 and 3 miles from the DAEC stack.
Precipitation -is collected monthly from one location and analyzed for gamma-emitting isotopes.
Quarterly composites are analyzed for tritium.
Milk samples are collected monthly from one indicator and one control location during the non-grazing season, October through April, and biweekly during the grazing season, May 1 through September 30. The samples are analyzed for iodine-131 and gamma-emitting isotopes.
For additional monitoring of the terrestrial environment, grain, hay and broad leaf vegetation samples are collected annually, as available, from seven locations: one control (D-108) and six indicators (D-16, D-57, D-58, D-72, D-94, D-96, and D-109). Grain, hay and broad leaf (green leafy) vegetation samples are analyzed for gamma-emitting isotopes and at least one broad leaf vegetation is analyzed for iodine-131.
If cattle are slaughtered for home use, a meat sample is collected annually, during or immediately following a grazing period from animals grazing on-site. The sample is analyzed for gamma-emitting isotopes.

Program Description (continued)
Potable ground water is collected quarterly from a treated municipal water system (D-53), the inlet to the municipal water treatment system (D-54), three additional indicator locations (D-55, D-57, D-58) and one control location, (D-72). An additional six site monitoring wells were added to the program in 2007. The samples are analyzed for gross beta and tritium. If gross beta activity exceeds ten times the yearly mean of the control samples, gamma isotopic, strontium-89 and strontium-90 analyses are performed.
Soil samples are collected once per year at two indicator locations (D-15a and D-16).
The samples are analyzed for strontium-90 and gamma-emitting isotopes.
Surface water is collected monthly from four river locations, D-49 (Lewis Access, Control, 4 mi.
upstream), D-50 (Inlet), D-51 (Discharge) and D-61 (1/2 mi. downstream of discharge. In addition, Pleasant Lake (D-99) surface water and sewage effluent from location (D-107) is also monitored.
Thel monthly samples are analyzed for gamma-emitting isotopes. Tritium analyses are performed on quarterly composites from each location.
The aquatic environment is also monitored by upstream and downstream (D-49 and D-61) semiannual collections of fish.
River bottom sediment is collected semiannually at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage plant (D-107a). The samples are analyzed for gamma-emitting isotopes.
3.3 Program Execution The program was executed as described in the preceding section with the following exceptions.
(1)
Thermoluminescent Dosimeters:
TLDs for location D-10 and D-28 were missing for the third quarter, 2007. The TLDs were lost in the field.
(2)
Milk:
No milk was available from location D-109 in December of 2007. The farm has gone out of the dairy business. This constitutes a missed sample per the minimum requirements of the ODAM.
(3)
Vegetation No broadleaf vegetation was available from locations D-58, D-72, D-94 and D-96 for the June, 2007 collection.
No forage samples (hay and grain) were available from locations D-58 or D-96 for the September-October, 2007 collection.
(4)
Sediments River sediments taken on 05/14/2007 did not meet the required six month collection frequency. This constitutes missed samples per the minimum requirements of the ODAM.
5
Progqram Execution (continued)
(5)
Precipitation The required lower levels of detection could not be achieved for precipitation sampled 02/22/2007. Not enough volume was available for analysis (lOOml.). This constitutes a missed sample per the minimum requirements of the ODAM.
(6)
Corrections to the 2006 Report Sampling points for locations D-111, D-112 and D-113 were listed incorrectly in Table 5.3 as 110, 111 and 112. The correct sample points should read 111, 112 and 113.
The air sampling stations listed in Table 5.4 were not updated from the 2005 report. Air particulates / air iodine samples were collected from stations D-3, D-5, D-6, D-7, D-1 1, D-13, D-15 and D-16 in 2006.
Table 5.4, the code RS was used for River Bottom Sediment. As per Table 5.5, the code used should have been BS for Bottom Sediment.
3.4 Laboratory Procedures The iodine-131 analyses in milk were made using a sensitive radiochemical procedure involving separation of the iodine using an ion-exchange method, solvent extraction and subsequent beta counting. Levels of iodine-131 in vegetation and concentrations of airborne iodine-131 in charcoal samples were determined by gamma spectroscopy.
Gamma-spectroscopic analyses were performed using high-purity germanium (HPGe) detectors. The gamma isotopic analysis provides a spectrum with an energy range of 80 to 2048 KeV. Specific isotopes included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but may not be listed.
Tritium was measured by liquid scintillation.
Analytical Procedures used by Environmental, Inc. are on file and are available for inspection.
Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't of Energy, Edition 28, 1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1984.
Environmental, Inc., Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained.
Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2003 ). The QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs.
Results obtained in crosscheck programs are presented in Appendix A.

3.5 Proqram Modifications Milk Milk from location D-109 was no longer available after the November 6, 2007 collection. The dairy has gone out of business.
Surface water Additional surface water sampling from locations D-49 (Lewis Access, Control) and D-99, (Pleasant Creek Lake) was initiated in 2007. The samples are analyzed for tritium and gamma emitting isotopes.
An analysis for low-level iodine-131 was added to the program in November of 2007, for two surface water locations, D-49 and D-61 (one half mile downstream).
Ground water Ground water monitoring of an additional six on-site wells was added to the REMP in the first quarter, 2007, for analysis of gross beta and tritium. Analyses for strontium-89, strontium-90 and gamma emitting isotopes will be performed if the gross beta activity exceeds ten times the yearly mean of the potable water well control.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for the listing in Table 5.6.
Results are summarized in Table 5.7 as recommended by the Nuclear Regulatory Commission. For each type of analysis and sample medium, the table lists the mean and range of all indicator and control locations, as well as that location with the highest mean and range.
Tabulated results of measurements are not included in this section, although reference to these results will be made in discussion. A complete tabulation of results for 2007 is contained in Part II of the Annual Report on the Radiological Environmental Monitoring Program for the Duane Arnold Energy Center.
4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 2007.
4.2 Proqram Findinqs Results obtained show background levels of radioactivity in the environmental samples collected outside of the Site Protected Area in 2007.
Low concentrations of tritium were identified in some groundwater, surface water and precipitation samples collected within the site Protected Area. In no instances were the REMP threshold reporting levels exceeded. (ODAM, Table 6.3-3)
Airborne Particulates The average annual gross beta concentrations in airborne particulates were identical at the 3
indicator and control locations (0.031 pCi/m ) and similar to levels observed from 1992 through 2006. The results are tabulated below.

Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation (Arnold and AI-Salih, 1955) was detected in all samples, 8
Program Findinqs (continued)
Airborne Iodine 3
Weekly levels of airborne iodine-1 31 were below the lower limit of detection (LLD) of 0.03 pCi/m in all samples.
Ambient Radiation (TLDs)
At twelve* air sampling locations, the TLD readings averaged 17.0 and 17.3 mR/quarter for indicator and control locations, respectively. At locations within a half mile, one mile and three mile radius of the stack, measurements averaged 18.5 mRlquarter, 19.4 mR/quarter and 16.8 mR/quarter, respectively. The average for all locations was 17.9 mR/quarter. This is lower than the estimated average natural background radiation for Middle America, 19.5 mR/quarter, which is based on data on Pages 71 and 108 of the report, "Natural Background Radiation in the United States" (National Council on Radiation Protection and Measurements, 1975). The terrestrial absorbed dose (uncorrected for structural and body shielding) ranges from 8.8 to 18.8 mrad/quarter and averages 11.5 mrad/quarter for Middle America.
Cosmic radiation and cosmogenic radionuclides contribute 8.0 mrad/quarter for a total average of 19.5 mrad/quarter.
No plant effect is indicated.
- There are currently eight active and four inactive air sampler stations.
Precipitation Precipitation from the on-site location D-16 was analyzed for tritium and gamma-emitting isotopes. No tritium activity was measured above the LLD of 174 pCi/L. No gamma-emitting isotopes were detected.
During May, 2007, an additional forty-five rain-water samples were collected in the Site Protected Area in closer proximity to the reactor building vent shaft release point. Downwind of the release point, concentrations of tritium measured from 158 to 2,666 pCi/L. No tritium was detected in the upwind samples. In no case did concentrations exceed the threshold for reportability of 20,000 pCi/L for these samples. Results of the testing are listed in Part II, Appendix A, Supplemental Analyses.
Milk lodine-131 results were below the detection limit of 0.5 pCi/L in all samples.
No gamma-emitting isotopes, except naturally occurring potassium-40, were detected in any milk samples. This is consistent with the finding of the National Center for Radiological Health that most radiocontaminants in feed do not find their way into milk due to the selective metabolism of the cow. The common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health, 1968).
In summary, milk data for 2007 show no radiological effects of plant operation.

Program Findings (continued)
Ground Water (potable)
The annual mean for gross beta activity averaged 4.1 pCi/L, similar to levels observed from 1991 through 2006. The location with the highest mean (6.4 pCi/L) was D-58, a farm 1.0 mile distant from the plant.
tritium activity measured below the LLD of 193 pCi/L in all samples. No effect from plant operation is indicated.
Ground Water (Site Monitoring Wells)
Twelve on-site monitoring wells (six shallow and six intermediate depth) were sampled in 2007 and analyzed for gross beta and tritium.
The annual mean for gross beta activity in six intermediate depth wells measured 2.7 pCi/liter.
Measurements for the shallow wells averaged 5.6 pCi/liter. The highest mean (10.8 pCi/L) was observed at shallow well MW-6A. Analyses for gamma emitting isotopes, strontium-89 and strontium-90 were performed and it was determined that the most likely, cause of the higher beta activity was contribution from naturally-occurring isotopes. No plant effect was indicated.
Tritium was identified in one of twenty four samples taken from the intermediate depth wells.
Intermediate depth well MW-05B, located SW of the plant in the overflow parking-lot, measured 243 pCi/liter, for the sample collected September 24th 2007. Tritium was identified in five of twenty-four samples taken from the shallow wells and has been attributed to "washout" from gaseous effluents. (See Program Findings for Precipitation)
Vegetation Iodine-131 concentrations in broadleaf vegetation were below the LLD level of 0.029 pCi/g wet weight in all samples.
Except for potassium-40, which was observed in all vegetation samples ( broadleaf, grain, and forage), all other gamma-emitting isotopes were below detection limits. No effect from plant operation is indicated.
Soil Strontium-90 activity measured 0.032 pCi/g dry weight in one of the two on-site locations.
Cesium-137 activity measured 0.13 pCi/g dry weight in one of two on-site locations. Strontium-90 and cesium-1 37 activities are similar or less than levels observed from 1991 through 2006, these levels are generally attributable to deposition of fallout from previous decades.
Naturally-occurring potassium-40 averaged 13.11 pCVg dry weight. No effect from the plant operation is indicated.
10
Program Findings (continued)
Surface Water Measurable tritium was detected on site in four of twelve D-107 (sewage effluent) collections, at an average concentration of 292 pCi/L. This is well below the Environmental Protection Agency's drinking water standard of 20,000 pCi/L. For all remaining surface water collections, tritium levels were measured below the LLD level of 178 pCVL.
The source of the tritium during the summer months has been attributed to recapture of Gaseous Effluent Tritium.
Tritium, in the form of tritiated water vapor, is condensed by building air conditioning units and air compressors. The condensation from those condensers is routed to the sewage treatment facility and the transformer pit.
The source of tritium in February and March of 2007 is urine from occupationally exposed radiation workers. A calculation was performed that demonstrates the relationship between the concentration of airborne tritium in the plant and the concentration of tritium in the sewage treatment plant liquid effluent. Radiation workers breathing the very low concentrations of tritium vapor in the plant work environment will transport, via their urine, small but measurable quantities of tritium to the plant sewer system.
All gamma-emitting isotopes were below their respective LLDs.
No plant effect on surface water outside of the Site Protected Area is indicated.
Fish With the exception of naturally-occurring potassium-40 no gamma-emitting isotopes were identified in edible portions of fish. The potassium-40 level was similar at both the indicator and control locations (2.89 and 2.88 pCi/g wet, respectively). No plant effect on the fish population is indicated, River Sediments River sediments were collected in May and September, 2007, and analyzed for gamma-emitting isotopes. Potassium-40 activity ranged from 4.79 - 12.96 pCi/g dry weight and averaged 9.0.0 pCi/g dry weight.
Trace Cs-137 activity was detected in both the control and discharge locations (D-50 and D-51) at concentration of 0.041 and 0.063 pCi/gdry weight, respectively.
All other gamma-emitting isotopes were below detection limits. There is no indication of a plant effect.

¢ Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses (F).
d Locations are specified by: (1) Name and code (Table 5.3); and (2) distance, direction and sector relative to reactor site.
e Non-routine results are those which exced ten times the control station value for the location. If a control station value is not available, the result is considered non-routine if it exceeds ten times the preoperational value for the location.
f One sample of precipitation was eliminated from the LLD calculations due to low volume (100ml.).

January through December, 2007
Appendix A Interlaboratory Comparison Prog.ram Results Environmental, Inc., Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
Results in Table A-1 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.
The results in Table A-2 list results for thermoluminescent dosimeters (TLDs), via International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.
Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house "blank" samples for the past twelve months. Data for previous years available upon request.
Table A-5 lists REMP specific analytical results from the in-house "duplicate" program for the past twelve month,,
Acceptance is based on the difference of the results being less than the sum of the errors.
Complete analytical data for duplicate analyses is available upon request.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
Results in Table A-7 were obtained through participation in the environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).
Attachment A lists acceptance criteria for "spiked" samples.
Out-of-limit results are explained directly below the result.

APPENDIX B DATA REPORTING CONVENTIONS B-1
Data Reportinq Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.
2.0. Single Measurements Each single measurement is reported as follows:
x +/- s where:
x = value of the measurement, s = 2cr counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is less than the lower limit of detection L, it is reported as: < L, where L = the lower limit of detection based on 4.66a uncertainty for a background sample.
3.0. Duplicate analyses 3.1 Individual results: For two analysis results; x1 + si and x2 + s2 Reported result:
x +/- s; where x = (1/2) (xI + x2) ands= (1/2) VS2 +s 2 3.2.
Individual results:
< L1, < L2 Reported result: < L, where L = lower of Li and L2 3.3.
Individual results:
x +/- s, < L Reported result:
x +/- s if x > L; < L otherwise.
4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x,, x2...
Xn are defined as follows:
=
\\jx-x) 2 X~
~Xn-i 4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.
4.5 In rounding off, the following rules are followed:
4.5.1.
If the number following those to be retained is less than 5, the number is dropped, and the retained number s are kept unchanged. As an example, 11.443 is rounded off to 11.44.
4.5.2. If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1. As an example, 11.445 is rounded off to 11.45.

SUMMARY
OF THE LAND USE CENSUS D-1
Appendix D Summary of the Land Use Census The Duane Arnold Energy Center (DAEC) Land Use Census for 2007 was completed during September and October of 2007. All milk animals, any new residences, and any gardens greater than 500 square feet were identified within a three miles radius for each of the 16 meteorological sectors radiating from the DAEC. If none were identified within the three mile range, additional surveys were performed out to a distance of five miles in that sector.
The Cedar River was surveyed by boat on July 10, 2007 for downstream water usage from the DAEC to the city of Cedar Rapids. This survey identified no new usages of river water from previous surveys. Irrigation of the strawberry farm in Palo and recreational fishing remain the only identified food pathway uses of Cedar River water between the DAEC and the City of Cedar Rapids eight miles down-river.
There were 166 vegetable gardens identified within the three mile radius of the DAEC during the 2007 Census; which is six fewer than 2006. In addition, there was a change to the nearest vegetable receptor from the DAEC in 2007. A new garden was planted at the Frantz Residence at 4318 Power Plant Road, which is in the SW sector from the DAEC at a distance of one mile. The previous closest garden was at a distance of 3 miles.
There was one change in the location of milk animals within the three mile radius of the plant in the past year. Several pygmy goats are located at a small farm two miles to the SSW at 2901 Palo Marsh Road. Milk from these goats is not used commercially.
The locations of the nearest residence for each sector remained the same as 2006. In 2007, 21 new homes were built or were under construction within the three mile radius of the DAEC, as compared to 16 new homes in 2006 and 45 new homes in 2005. All of these new houses built in 2007 are located to the SSW in the town of Palo.
D-2
In accordance with the DAEC's Environmental Sampling Procedure ESP 4.4, "Land Use Census", no changes in land use were identified that would adversely affect the safe operation of the DAEC, or that would warrant an update of the DAEC Updated Final Safety Analysis Report (UFSAR). Examples of land use that would warrant an UFSAR update include new hazards near the DAEC such as new gas pipelines or new installations utilizing toxic gases.
FPL Energy Duane Arnold has committed to following NEI 07-07, "Nuclear Energy Institute's Industry Ground Water Protection Initiative:
Per NEI 07-07, the following information is presented:
Per Objectives 2.2 and 2.4, there were no on-site leaks or spills that warranted notification of state or local officials or other local stakeholders.
No radioactive reactor by-product material was identified in samples taken by the DAEC's Radiological Environmental Monitoring Program (REMP) above the threshold concentration levels for reporting.
" Both on-site and off-site ground water sampling/monitoring has been incorporated into the REMP. Consequently, all Ground Water Protection Program results are included as part of the Annual Radiological Environmental Operating Report. In addition, a summary of the supplementary precipitation samples that were taken are included in Appendix A to Part II of that report.

APPENDIX E ANNUAL RADIATION DOSE ASSESSMENT E-1
Appendix E Annual Radiation Dose Assessment The annual offsite radiation dose to a member of the public was determined by assessment of environmental dosimetry results and by calculations based on monitored effluent releases.
Section A.
Dose Contribution from Direct Radiation Direct radiation dose from the operation of the DAEC was reported by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).
- 1. Pre-operational and 2007 TLD results were evaluated with a paired difference statistical test.
The evaluation concluded that there were no significant differences in the TLD populations for the 0.5 mile, 1 mile and 3 mile TLD populations.
- 2. As stated in Part 1 of this report, no plant effect was indicated by the TLDs when dose results were compared to the estimated average natural background for Middle America.
Section B.
Estimated Offsite Dose from Effluent Releases The contribution of dose to a member of the public most likely to be exposed from liquid and gaseous effluent releases was calculated using the Meteorological Information and Dose Assessment System (MIDAS) computer program in accordance with the ODAM. The calculation methods follow those prescribed by Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I".
Following calculation of offsite doses, the appropriateness of REMP sampling station types and locations was reviewed. The current sampling scheme was determined to be more than adequate for the identified receptors.
Results of the MIDAS dose calculations are displayed below.
1.) The hypothetical maximally exposed organ due to liquid effluents was the liver of a child, with an estimated dose equivalent of 0.0000225 mrem.
2.) The whole body dose equivalent to the hypothetical maximally exposed individual due to liquid effluents was 0.0000225 mrem.
3.) The maximum dose to air at the site boundary from noble gases released was 0.00118 mrad from gamma radiation at 535 meters towards the South-South-West.
4.) The maximum dose to air at the site boundary from noble gases released was 0.0951 mrad beta radiation at 535 meters towards the South-South-West.
5.) The whole body dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.00194 mrem, at 974 meters towards the South-West.
E-2
6.) The skin dose equivalent to the hypothetical maximally exposed individual from noble gases was 0.00199 mrem, at 974 meters towards the South-West.
7.) The hypothetical maximally exposed organ due to airborne iodines and particulates with half-lives greater than eight days was the skin of a child at 805 meters West, with an estimated dose equivalent of 0.010 mrem.
==
Conclusion:==
No measurable dose due to the operation of the DAEC was detected by environmental TLDs in 2007. The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR 190.

1.0 INTRODUCTION
The following constitutes a supplement to the Annual Report for the Radiological Environmental Monitoring Program conducted at the Duane Arnold Energy Center, Palo, Iowa in 2007T Results of completed analyses are presented in the attached tables.
For information regarding sampling locations, type and frequency of collection, and sample codes, please refer to Part I, Tables 5.3 - 5.5 and Figures 5.1 and 5.2.
All concentrations, except gross beta and airborne iodine, are decay corrected to the time of collection. Airborne 1-131 is decayed to the midpoint of the collection period.
The gamma isotopic analysis provides a spectrum with an energy range of 80 to 2048 keV.
Specific isotopes included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, 1-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144.
Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but may not be listed.
