• 4 j 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

,i counsel the following: at the Monticello hearing but I do want to pass on to you promptly 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

• were similarly authorized under Section 20.304. (This uranium i

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-i posed of by burial in soil by a factor of 5,000. (The Appendix C

, 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

4 exemption was requested and granted.
