Dear Congressman agomarsino:

(7g-220S)

I am pleased to resp gd to your July 24, 1979 reft.rral.,of a letter from your constituents, Nr. and ttrs. Leroy Sauruwatari.

Since rulings and decisions related to the Diablo Canyon Nuclear Power Plant could be subject to review, by the Cormission, it would not be appropriate under current rules for the Commissioner to comment on $qur constituents'oncerns regarding Diablo.

Canyon at this time.

Therefore, your letter was'eferred to me.for reply.

Your constituents expressed concerns over the number of pounds of "white rain" and radioactive dust that Gould be emitted from Diablo Canyon during optimum and actual operating condign ons and what minerals this dust would contain.

While your constituents'etter does not ecifically de'fine "white rain," we assume that the term refers to the precipi tion of water in the areas around plants that have cooling towers.

This.precipi~tation is not radioactive except for possible trace amounts that would result frog it mixing with normal air-borne radioactive effluents from the plant.

Although Diablo Canyon, Units 1

5 2 do not have cooling towers, we have evaluated stations that do use cooling towers and have found that their impact on th environment from the "white rain" effect to be negligible.

In regard to the number of pounds of radioactive dust per d y released from Diablo Canyon, we assume that your constituents were referrin+to the radioactive particulate that is not removed by filters and is released to" the environment.

Based on the expected gaseous effluents from b%th unIits~

during normal plant operation, we calculate that the total releaseyfrom both units would be less than 10 grams per year or 0.00006 pounds p~t.q day.,

The increase in radiation exposure due to the operation of Diablo Canyon,

"'nits 1

8 2 will be a very small fraction of that received from natura~l

(

background radiation.

Based on actual operating experience from opera'tiqg>>

nuclear

reactors, we conclude that there will be no discernible radiologi'ca~1 impact on the general public as a result of normal operation of the Diably I,

Canyon Station.
