I've been helping to update our state professional archaeologists council's  
(COSCAPA) Guidelines and Standards for Archaeological Investigations and a  
question came up recently regarding underwater projects. We don't have any  
specific guidelines other than to consult with the state underwater archaeology  
folks. Do any other states have guidelines and standards for underwater 
projects  conducted in a section 106 context? Do other states require underwater work 
 as often as they do terrestrial work? thanks, Carl  Steen
