Oil-Spill Risk Analysis Reports
   
The Minerals Management Service produces oil-spill risk analyses (OSRAs) for proposed Outer Continental Shelf (OCS) oil and gas lease sales and developmental activities.

These analyses estimate the potential oil-spill risks that may be associated with offshore activities that occur once leases are awarded. It is important to remember that these are projections based on probability only. There is no way of knowing in advance, which tracts will be leased, which leases will see activity, what types of hydrocarbons may be recovered if any, the size of an actual spill, or even the prevailing weather conditions, should an accident occur.

Our most recent OSRA reports listed below are available in Adobe Acrobat pdf format.
