DAIRYLAND POWER COOPERATIVE LA CROSSE BOILING MATER REACTOR (LAC 3WR) PROVISIONAL OPERATING LICENSE NO. DPR-45 SU3MITTAL OF INFORMATION - LACBWR FES Deir Mr. Vaslow: Pursuant to our telephone conversation last week, I verified the chemical additions to our component cooling water systems at LAC 3WR. During 1979, 800 grams of Mg 800 grams of K2Cr2 7 and 11 Kg of Na2CrO.; were added

CrO4, 0

to the component cooling water systems to nake up for losses due to maintenance and leaks in the systems. Heating boiler chenicals added during 1979 totalled 56.1 liters of Morphaline and 3.7 liters of Hydrazine. In reviewing the information which you had previously noted in Section 3.7.1, the chemical additions to the systams are slightly different than the 1971 data. As discussed, we administratively control the discharge concentration of Chrc=ium to less than.005 ppm. Additionally, you requested information on monitoring wells at our Genoa site. As I discussed with you, we do monitor ground water around our Genoa #3 coal pile and ash disposal lagoon. The data that we have accumulated over the past years is shown on the attached reporting log. The T.oni-toring wells are located as indicated on the drawing. For reference purposes, these wells are at the south end of our site and a considerable distance from the Genoa al ash dis-posal lagoon. I don't reall; 1:now if you can use this infor-nation. We do not have any monitoring wells near the Genoa =1 ash disposal lagcon. In T.y Deccaber 12th letter to Mr. Ballard, in response to questions which were sent to us in the November 16, 1979 letter, we did no: hate the purchase power costs available 1871 301 ym a3 a z s

Mr. Fred Vaslow December 28, 1979 at the time of that submittal. Since that time we have been able to determine the purchase power costs during 1977, 1978 and through October 1979. These costs are as follows: 1977 16.7 mills /kWh 1978 28.0 1979 (through Oct. 'i9) 27.3 It should be explained that these costs are for pur-chasing energy in the Powcr Potl for scheduled outages or emergencies. There are no demand charges in these rates and, hence, they are ec= parable to the fuel, operation, and mainten-ance costs transmitted to Mr. Ballard in the December 12th letter. If you have any further cuestions on this, please do not hesitate to give me a call. Yours truly, DAIRYLA'.'D POWER CCCPERATIVE bYlin 1 - W Thomas A.
