Dear Mr. Reid:

Enclosed is the additional information requested in your letter of September 15, 1976 whi,:h we indicated would be furnished later in our letter of November 17, 1976. Specifically, information is contained in response to questions 3, 4, 6b and 7 of Enclosure 1 of your letter. Please contact us if there are further questions on this i.nformation. Very truly yours, DAlpYLAND POWER COOPERATIVE Joh:Q Madgett, Gene al Manager JPM/cw Enclosure cc: J. Keppler, Reg. Dir., NRC-DRO III $270 { fo D-Ot.M e P

3. Provide the information requested in items 3, 4o Sb, or 6b, 7 and 8 of Enclosure 2 or our February 18, 1976 letter. Based on considerations in Draft Regulatory Guide 1.DD, provide estimates of relative concentration (X/Q) and deposition (D/Q) at locations specified in response to item 2 above for each release point specified in response to item 1 above. 3. Ectimates of relative concentration (X/Q) and deposition (D/Q) at specific locations are provided in the attached tables. Table I shows the estimates of X/O and D/0 for residences in the vicinity of LACBWR. Table II shows the D/0 for pasturing and meat animals in the surrounding area and Table III shows the D/0 for milk cows and goat pastures. 4. Provide a detailed description of the meteorological data r models and parameters used to determine the X/Q and D/O values. Include information concerning the validity and accuracy of the models and assumptions for your site and the representativeness of the meteorological data.used. 4. The La Crosse Boiling Water Reactor has insufficier.t meteorological data to be developed for use in long term dispersion calculations. Thus, the meteorological data from the La Crcsse, Wisconsin Weather Station for the years 1967-71 was used to estimate the X/Q and D/Q for the LACBWR vicinity. The La Crosse weather station is located in the Mississippi River Valley approximately 22 miles north of the LACBWR plant site. The wind speed and directional data is col-lected at a height of ten meters. Since the valley at the La Crosse location has a north by northwesterly orientation as compared to the site's northerly orientation, the meteorological data for La Crosse was rotated one sector to be more representative of site topagraphy.

Thus, North becomes North-Northeast.

The Straight Line Airflow Model as described in Regulatory Guide 1.111 was used to estimate the annual X/Q and D/O was estimated by the method suggested in the same regulatory guide. For locations in the river valley the equation was multiplied by a factor of 1.5. Since LACBWR's gaseous re-lease is elevated the plume rise was determined according to the method of Briggs. The plume rise for neutral and unstable conditions was calculated by the formula -1 ah = bpr = 1. 6 F u X2/3 %M

T. and the plume rise during stable conditions by oh = hpr = 2.9 (F/us)l/3 The effective height of emission was determined by sub-tracting the bluff height of 525 feet from the total plume rise as shown below. heff = hs + hpr - ht Where 1 heff = the effective plume rise hs = stack height l hpr = plume rise above point of release h = height of surrounding terrain t When the effective plume rise is < 0 the release is treated as a ground level release. Wind speeds at the height of ten meters were corrected to a height 107 meters.by a power formula for winds during stable and unstable conditions. The models used for these estimates are considered to be conservative for this appli-cation since they fail to take into consideration the complex terr.ain in which LACBWR is located. Turbulent diffusion, channeling effects and potential for local circulation are not considered. It has been estimated by Mahoney that even moderate wind direction shear results in effective increases in plume dispersion which are orders of magnitude larger than those expected in the absence of shear. A field study by Roffman showed that during stable conditions and elevated terrain that flat surface models over-predicted the airborne concentrations of SO2 by a factor 6.2 - 11.2. Hence, it would appear that the application of Straight Line Airflow Model is a conservative application of the model to LACBWR's location. 6.b. Describe the representativeness of the available data with respect to onsite and near site atmospheric transport and l diffusion conditions, and with respect to expected long term 1 conditions at and near the site. l l 6.b. The weather data used for X/O and D/0 estimates is repre-sentative of the winds that occur in the Mississippi Valley. It recognized that while the orientation of the river valley at La Crosse and the plant site are dif ferent, this difference is compensated by the rotation of the wind frequencies by one sector (North becomes North-northeast). ._J

7. Describe airflow trajectory regimes of importance in tranG-porting effluents to the locations for which dose ca)cu-1ations are made. 7. The airflow trajectories of importance are the increased wind frequency up and down the river valley caused by the topography and the flow of wind towards the bluff. The prevalent winds towards the bluff are the most important because the plant's release is then treated as a ground level release for most conditions. O e e
