& 23 Note to Mr. Price:
The April 18 draft 'of the Monticello Waste Disposal Permit has been updated to conform to the May 12 draft given to'us yesterday by John Ladalich.
Copies of both drafts are attached.
Changes are noted on pages-3,4,5,6,8, and 9 some of the "if necessary"-
and "to the full extent feasible and reasonable" remarks, but not all of them, have been deleted.
The most ai6nificant change, also noted yesterday by Mr. Eadelic.h,:is the deletion of the remarks relating to the determination of the mixing zone beyond the outfall.
Please note that the' revised draft has not yet been sent-to the Joint Committee.

,Special Conditinns Relating to Radioactive Wanten i
1.
It is the policy of the Agency that. ell radioactive pollution of the environment nhall be held to the lowest level that is attainnble within the limitations imposed by technological foanibility and economic reasonable-In no case chell members of the public be expeced to rediation beyon'd i
ness.
the linits reconmended by the International Commiccion on Radiological Pro-a tection.
In addition, the actual Jevels of radietion exposure of members of the public shall be kept as fur below those limits as por-ible, conciatent.i.
l with technological feasibility and reasoncblenesc of cost, i
2.
In keeping with the above policy of the Agency, ell practical measurno for treatment, control and containment of radioactive ucates from the lionticalla nuclear Dencrating plant of the Northern States Power Company nhall be employed for the purpose of preventing the release of radioactivity to the environment.
Such measures shall include at least, but not be limited to:
(a) all moonures for the treatment, control and containment of liquid and'geoccus redioactive effluents that are indicated in the Final Safety Analysis Report of the Northorn States Power. Company, Unit 1, Monticello nuclear generating plant; and W

(b) routino removal of radioindinc and halogens from tha DHueous effluento to the. full extent fuusible, the du0ron of-treat. ment and removc1 being at least the equivalent of that pro-vided by cffective ectivated charcoal filtrntion of the entiro air ejector offgan flota; cnd (c) routine ion exchange treatment (Powdox demineralization or equivalent) of the combined low purity wastco (priraarily from floor drain 9) cod the neutrn1.ized chemical westco (primarily from laboratory drains and shop decontamination colution drains).
The combined ectimated flow is 8,000 gal /dny; ond (d) initial incpection of fuel rodo for surf ace conteminn-tion with uranium bnfore uso in the reactor, and decontemination or replacement of fuel roda that hnvc detectable or si nificant 0
emounts of uronium on their external surfacos, so oc to prevent the use of such fuel rods in the reactor.
The plant operator shell report in deteil to the aguncy the mt acures taken in this regard before startup of the reactor; and (c) initial thorough inspection of fuel rods to identify those that might devnlop fission product leaks, and rejection
.a of such rods for use in 'the reactor; to the full extent possibic, development and application of methoda and techniqueo for locating and identifying lenking funl rods ofter operation of the reactor bnD nc, so that such rods may be removed during usual fuel replace-i ment operations or, at other times, to prevent excesnive relenou of rndicactivity to the environment.
The operator shall report in detail to the A ency the actual measures taken in both of these D
rn0erds before startup of the reactor.
If necessary, he shall initiate rescarch and development activiities designed to develop the needed offective procedures.

After a 15-minute dalcy, the air ejector offgas isolation valve shall eutomatically closc, shutting down the reactor, if the radioactivity release rate has not been successfully reduced to the weekly release rate limit, or less.
