possibilities indicated in this area might also have applicability in 

 several other areas or methods of relatively shallow disposal. 



CHAIRMAN HESS: Thank you, Dr. Frye. 



Does anyone wish to comment on this report? 



You will notice that the tasks as given out were changed some- 

 what after the committees got to work. "Deep" and "shallow" do not 

 apply any more. 



Someone wanted to know what we meant by deep and shallow. 

 The first committee did not comment on how deep they considered 

 deep, but I would think it would mean 1000 to 10,000 feet for the dis- 

 posal of materials underground. 



DR. HUBBERT: I think the consensus was that deep means as- 

 deep-as-possible . (Laughter) 



CHAIRMAN HESS: What is deep to a geologist may seem very 

 deep to a non-geologist or not deep at all. 



DR. HUBBERT: We can say ten or fifteen thousand feet is thor- 

 oughly practical, although in many cases depths of 5,000 to 10,000 

 feet, or even less, maybe satisfactory. 



The conference was adjourned at 11:30 a.m.
