SECTION A RADIOACTIVE EFFLUENT REPORT
INTRODUCTION The La Crosse Boiling Water Reactor (LACBWR), also known as Genoa Station No. 2, is located on the east bank of the Mississippi River near Genoa, Vernon County, Wisconsin. The plant was designed and constructed by the Allis-Chalmers Manufacturing Company. It was completed in 1967 and had a generation capacity of 50 MW (165 MW(th)). The reactor is owned by Dairyland Power Cooperative (DPC).
The reactor went critical in July 1967 and first contributed electricity to DPC's system in April 1968. After completing full power tests in August 1969, the plant operated between 60% and 100% full power, with the exception of plant shutdowns for maintenance and repair.
In April of 1987 plant operation was ceased. The reactor was defueled and placed in a SAFSTOR mode. In August of 1987 a possession-only license was received. In 2007 the reactor vessel was removed from the site and buried at the Barnwell waste repository. In 2012 all spent fuel was placed in dry storage and placed at the LACBWR ISFSI.
In accordance with LACBWR Appendix C Section 2 of the Quality Assurance Program Description (QAPD), this document is the Radioactive Effluent Report for the Period January 1 through December 31, 2014.

EFFLUENT AND WASTE DISPOSAL REPORT (Supplemental Information)
FACILITY: La Crosse Boiling Water Reactor LICENSEE: Dairyland Power Cooperative DOCKET NO. 50-409 & 72-046 1.0 REGULATORY LIMITS 1.1 Gaseous Effluent Release Limits:
LACBWR's stack effluent release limitations for gaseous effluent releases of radioactive material limits the release rate of the sum of the individual radionuclides, so that the dose rates to members of the public beyond the Effluent Release Boundary do not exceed 500 mRem/year to the whole body and 1500 mRem/year to a critical organ from H-3 and particulates with half-lives greater than 8 days as per the requirements of the Offsite Dose Calculation Manual (ODCM).
Also, in accordance with 10 CFR 50, Appendix I, the ODCM limitations for gaseous effluent radioactive material limit the air dose to a member of the public from noble gases in areas beyond the Effluent Release Boundary to less than 5 mRad gamma and 10 mRad beta per calendar quarter, and less than 10 mRad gamma and 20 mRad beta per calendar year. The dose limits from H-3 and particulates with half-lives greater than 8 days are less than 7.5 mRem per calendar quarter, and less than 15 mRem per calendar year to any organ.
Cumulative dose contributions from gaseous effluent releases are determined in accordance with the LACBWR Offsite Dose Calculations Manual.

EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd) 1.2 Liquid Effluent Release Limits:
LACBWR's liquid effluent release limitations for liquid effluent releases are those concentrations specified in 10 CFR 20 Appendix B, Table 2, Column 2. The values reported in tables 2A and 2B, Liquid Effluents, are based on dilution of the effluent with the Genoa Station No. 3 condenser cooling water flow prior to discharge to the Mississippi River. No credit is taken for further dilution in the mixing zone of the Mississippi River.
Also, in accordance with 10 CFR 50, Appendix I, the dose commitment to a member of the public from radioactive materials released in liquid effluents to areas beyond the Effluent Release Boundary are limited to less than 1.5 mRem whole body and 5.0 mRem organ dose per calendar quarter, and less than 3.0 mRem whole body and 10 mRem organ dose per calendar year via the critical ingestion pathway.
Cumulative quarterly and annual dose contributions from liquid effluent releases are determined for the adult fish ingestion pathway in accordance with the LACBWR Offsite Dose Calculation Manual.
1.3 Solid Radioactive Waste All solid radioactive wastes are handled in accordance with a Process Control Program as defined by LACBWR procedures in order to assure that all applicable transportation and burial site disposal requirements are met.

EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd) 2.0 EFFLUENT RELEASE CONCENTRATION LIMIT The Effluent Release Concentration used to calculate permissible release rates are obtained from 10 CFR 20, Appendix B, Table 2, Column 2.
3.0 AVERAGE ENERGY The release rate limits for LACBWR are not based on average energy.
4.0 ANALYTICAL METHODS 4.1 Liquid Effluents Liquid effluent measurements for gross radioactivity are performed by HPGe gamma isotopic analysis of a representative sample from each tank prior to discharge. In addition, each batch discharged tank sample is analyzed for alpha and tritium activity concentrations using an IPC. A composite sample is created by collecting representative aliquots from each tank batch discharged during a calendar quarter. This composite is analyzed for Iron-55 and Strontium-90 by a contractor on a quarterly basis.
4.2 Airborne Particulates Airborne particulate releases are determined by HPGe gamma isotopic analysis.
This analysis is performed by analyzing a glass fiber filter paper, taken from the stack monitor which continuously samples from an isokinetic point monitoring the stack effluent. This filter is changed and analyzed on an approximate weekly basis and analyzed within 7 days after removal. This filter is also analyzed for alpha activity. A quarterly composite of these filters is sent to a contractor for Sr-90 analysis.

EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd) 4.3 Fission and Activation Gases With the removal of spent fuel from the site no fission gases remain. In 2013 the monitoring for fission and activation gases was eliminated.
4.4 Tritium Tritium releases are determined by taking a grab sample of the stack atmosphere at the effluent of the stack monitor. Tritium, as tritiated water, is removed from the sample stream by condensation, using a cold trap. The condensed water vapor is then distilled and the distillate is analyzed for H-3 concentration (pCi/cc),
by internal liquid scintillation spectrophotometry and the results are expressed in terms of tritium release rates. The tritium grab samples were obtained on at least a once/month basis. This process was discontinued in August of 2014 with the approved changes to the ODCM.
5.0 BATCH RELEASES 5.1 Airborne All airborne effluent releases at LACBWR are from a single Continuous-Elevated Release Point.
5.2 Liquid All liquid effluent releases at LACBWR are batch releases as described in the ODCM. This is summarized as follows:

EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd) 8.0 OFFSITE DOSE CALCULATIONS
SUMMARY
AND CONCLUSIONS:
8.1 Gaseous Effluent Releases The maximum quarterly offsite gamma dose due to noble gases was 0.00 mRad.
The cumulative 2014 annual offsite gamma dose due to noble gases was 0.00 mRad.
The maximum quarterly offsite beta dose due to noble gases was 0.00 mRad.
The cumulative 2014 annual offsite beta dose due to noble gases was 0.00 mRad.
The maximum quarterly offsite dose to any organ from the release of H-3 and all radionuclides in particulate form with half-lives greater than 8 days was approximately 4.36E-04 mRem. The cumulative 2014 annual maximum organ dose from these radionuclides was also approximately 5.43E-04mRem.
The highest historical annual average X/Q equal to 1.82 E-6 sec/m3 for the period 1985-1987 for the worst case offsite receptor location, in accordance with the ODCM, was used to calculate these offsite dose values.
8.2 Liquid Effluent Releases The maximum quarterly organ dose from liquid releases was approximately 1.38E+OOmRem. The cumulative 2014 annual organ dose was approximately 1.76E+00 mRem. The maximum quarterly total body dose for liquid releases was approximately 8.76E-01 mRem, and the cumulative 2014 annual total body dose was approximately 1.13E+00 mRem.
12
EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd) 8.3 Conclusion All calculated offsite doses were below ODCM limits.
9.0 OFFSITE DOSE CALCULATION MANUAL (ODCM) REVIEW Revision 15 to the ODCM was issued in August of 2014. The majority of the changes were made to reflect the current status of the facility with respect to its calculated radionuclide inventory. The calculation confirms it is not possible to either (a) exceed the annual dose limits, or ( b) reach the current airborne effluent monitor instantaneous release rate setpoint of 1500 mrem/yr. The LACBWR facility discontinued the monitoring of main stack air, offsite particulate air, OSL quarterly (not including ISFSI) monitoring as well as fish sampling from the Mississippi river.
10.0 PROCESS CONTROL PROGRAM (PCP) REVIEW The PCP was not reviewed in 2014.

SECTION B ANNUAL RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT
EFFLUENT AND WASTE DISPOSAL REPORT - (cont'd)
INTRODUCTION:
The Radiological Environmental Monitoring (REM) Program is conducted to comply with the requirements of the ODCM and in accordance with 10 CFR 50 Appendix I and 10 CFR 72.104. The REM Programprovides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which could potentially lead to radiationdoses to Members of the Public resulting from plant effluents. Environmentalsamples are taken within the surroundingareas of the plant and in selected control or background locations.
The monitoringprogram at the LACBWR facility includes monitoring of liquid and gaseous releases from the plant, as well as environmental samples of surface air,river water, river sediment, milk, fish, and penetratingradiation.
The REM program theory supplements the Radioactive Effluent analyses by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways using the methodology of the Offsite Dose Calculation Manual (ODCM).
An InterlaboratoryComparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive materialin environmental samples are performed.

FIGURES 3 & 4 These maps show the location of LACBWR's OSL's.
FIGURE 5 This map shows the location of ISFSI OSL's.
TABLE 1 This table shows the OSL locations at the ISFSI.
TABLE 2 This table shows the sampling frequency of the various environmental samples and the analyses performed on these samples TABLE 3 This table shows the permanent monitoring stations used in LACBWR's environmental program.
TABLE 4 This table shows the OSL locations.
TABLE 5 This table shows the number of various samples collected and analyzed during 2014.
2.0 RESULTS OF THE 2014 RADIO-ENVIRONMENTAL MONITORING SURVEYS During 2014, activity levels in the local environment were normal, indicating no significant plant attributed radioactivity.
2
RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT - (cont'd) 2.1 PENETRATING RADIATION The environmental penetrating radiation dose is measured by optically stimulated luminescent (OSL) dosimetry.
2.1.1 Plant - These OSL's were changed on a quarterly basis until August 2014 when the requirements of the ODCM were updated to eliminate the requirement to monitor plant related penetrating radiation. The OSL results for the LACBWR Plant from 2014 are shown on Table 6.
2.1.2 ISFSI - These OSL's are changed on a quarterly basis. Table 12 OSL results for 2014 are shown. A revision was made to Table 12 from 2012 and 2013, which are included in this report, as background exposure was not subtracted from the tables.
2.2 AIR PARTICULATE Air samples were collected continuously from various sites (see Table 3) around LACBWR. An air sampler was located 18 miles north of the plant in La Crosse, Wisconsin, to act as a control station. Particulate air samples were collected at the rate of approximately 30-60 Ipm with a Gelman Air Sampler. The air filter consists of a glass fiber filter with an associated pore size of approximately 0.45 pm. The particulate filters were analyzed weekly for gross beta activity with an internal proportional counter, and the monthly particulate composites are gamma analyzed for individual isotopic concentration.
TABLE 7 This table shows the weekly gross beta gamma activity concentration from the air particulate filters.
TABLE 8 This table shows the composite air particulate isotopic analysis.

RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT - (cont'd)
Comparison between the control station at La Crosse and the other stations near LACBWR indicate that there was no significant plant attributable airborne particulate activity. Air particulate samples were discontinued in August 2014 when the requirements of the ODCM were updated.
2.3 RIVER WATER River water was collected monthly and is now collected semi-annually. River water samples above at, and below the plant site are collected and are gamma analyzed for isotopic concentration. The river water gamma isotopic analysis results are shown in Table 12. The results indicate that there were no significant plant attributable radionuclides in the river water.
2.4 SEDIMENT SAMPLES Sediment samples are collected twice per year above, at, and below the plant outfall. These samples are gamma analyzed and these results appear on Table
- 13. They indicated that small amounts of plant-attributed radionuclides have accumulated in river sediments near the outfall. The amount of radionuclides in this sediment declined significantly after plant shutdown. These amounts have remained relatively constant the last few years.
2.5 FISH Fish samples were collected quarterly above and below the plant discharge. Fish samples are no longer required as per the updated ODCM. The results of gamma spectral analysis of edible portions of fish samples appear in Table 14.
There has been no significant accumulation of plant-attributed radionuclides in fish in the vicinity of LACBWR. Fish sampling has been eliminated as of August 2014 when the requirements of the ODCM were updated.
