SURIAL OF RADIOACTIVE WASTES IN MIMMESOIA I

Howard Shapar is preparing a reply to John Badalich's letter of November 2 regarding the burial of radioactive wastes in Minnesota.

I have no

?

information inanediately available concerning the statement medo by AEC counsel at the Monticello hearing but I do want to pass on to you promptly the following:

,i The December 1966 burial by 3M Cc spany of natural uranitse and thorium (in the form of contamination on equipment, etc.) -- a total of 4.83 millicuries, according to their report to Badalich --

l was authorised by Section 20.304 of AEC regulations (Part 20).

Prior AEC approval is not required in such situations.

(

I!

c; The July 1967 burial of 35.6 millicuries of enriched uranium and J. :,

the November 1968 burial of 3.5 millicuries of enriched uranium i

were similarly authorized under Section 20.304.

(This uranium undoubtedly was enriched to 937, since this is the material 3M requested and was granted a license to possess and use.)

1 It should be kept in mind, however, that Appendix C of Part 20 was C

I amended, effectiva May 22, 1970, and that the amendment, among other things, reduced the quantity of uraniurn 235 that.may be dis-posed of by burial in soil by a factor of 5,000.

(The Appendix C i

value was changed from 50 microcuries to 0.01 microcurie.

A single burial may consist of up to 1,000 times the Appendix C value.)

Thus, the 1967 and 1968 burials of enriched uranium would

,q not be authorized under curront AEC regulations unless e specific s

exemption was requested and granted.
