Do you want to address yourself to that question, sir ? 



Dr. Ketchum. Yes, sir. I believe we discussed this indirectly before 

 in that I have specifically identified toxic industrial waste, chemical 

 and biological warfare material and high level radioactive waste 

 disposal at sea should be prohibited, 



I was asked to define toxic industrial waste and I believe that I 

 sidestepped the question and failed to give a definition which would 

 have any legal continuity, any legal reality at all. 



In terms of the phased-out operations I was thinking of the opera- 

 tions which are already known to be damaging such as the disposal 

 of sewage sludge and dredging spoils off ISTew York Harbor and it is 

 happening in other parts of our coastal zone where we know that 

 these are damaging. 



We need to have alternate methods of disposing of this material 

 because it is being produced on a continuous basis. These I think should 

 be phased out as rapidly as the alternatives could be developed. 



Mr. DiNGELL. Earlier you mentioned specific instructions to the 

 Administrator when damaging effects of disposal operations are 

 already well known. 



What specific instructions would you have in mind? Again I indi- 

 cated to ^T^ou the possibility of your giving some comments on these 

 points after you have had an opportunity to reflect on them. 



Dr. Ketchtjm, I think I would almost be willing to quote directly 

 from the report of the Council on Environmental Quality which had 

 some rather specific statement that this type of material should be 

 prohibited, other types should be phased out in the course of time. 



Mr, DiNGELL, Are there any further questions of Dr. Ketchum ? 



Doctor, the committee is grateful to you. We thank you. You have 

 been most kind and most helpful to the committee. We appreciate 

 your assistance. 



Dr. Ketchtjm. Thank you for the opportunity of appearing before 

 you, sir. 



Mr. DiNGELL. Our next witness is Mr, Edward Langlois, of Port- 

 land, Maine. Mr. Langlois. 



Mr. Langlois, I notice you have an associate with you. If you will 

 identify yourself and your associate for the purpose of the record by 

 name and address, we will be happy to recognize you for your 

 statement.
