tional markings, etc., exists by virtue of one set of 

 statutes for U.S. territorial waters, and for the 

 Outer Continental Shelf via the Outer Continental 

 Shelf Lands Act."" 



Many matters not directly provided for by this 

 statute have been covered by terms of lease or 

 construction permits. For example, unused or 

 damaged structures are required to be removed 

 from the site. However, items not located on the 

 lease/permit site, or not "fixed structures or 

 artificial islands" such as vessels or mobile drilling 

 units not engaged in drilling, do not come within 

 the purview of these provisions. 



The Convention on the Continental Shelf, 

 Article 5(1) states: 



The exploration of the continental shelf and the 

 exploitation of its natural resources must not 

 result in any unjustifiable interference with naviga- 

 tion, fishing or the conservation of the living 

 resources of the sea. ^ ' 



This is one of the first major actions to relate 

 the competition of interest. However, no agency 

 presently appears to have the authority to enforce 

 this provision.

 United States v. Florida et al, 363 U.S. 121 (I960). By 

 the 1960 Supreme Court decisions in the United States- 

 Texas-Florida litigation-the Outer Continental Shelf 

 commences three marine leagues (nine miles) off the Gulf 

 Coast of these States. Since territorial waters extend only 

 to three miles, there exists off these States a belt six miles 

 wide in which no clearcut jurisdiction exists over naviga- 

 tional matters.
