In 1975 the Southern California area supported the follow- 

 ing offshore oil and gas operations and related facilities (all 

 State licensed unless otherwise indicated) : 

 Item Number 



Offshore 



Marine terminals 11 



Production platforms 14 (7 State, 7 Federal) 



Oceanfloor wells 5 



Artificial islands 6 



Onshore 



Major harbors 18 (plus 12 island caves) 



Refineries 12 



Shipyard and fixed plat- 

 form construction yards 5 

 Oil and gas separation 



and cleaning facilities 35 

 The level of oil and gas activity and construction of 

 facilities should eventually rise sharply as a result of 

 sales 35 (1975) and 48 (1979). In fact, the State of 

 California estimates that from 20 to 60 platforms ultimately 

 could be erected in Southern California coastal waters.
