Authorizes such governor to petition the Secretary to prohibit the leasing of areas within the administrative boundaries of the state that are between 50 and 100 miles off the coast.

Allocates to a coastal state 37.5% of: (1) any bonus bid paid for leasing rights in an OCS area if the Secretary has approved the state's request to allow leasing in that area; (2) lease rental payments, lease royalty payments, and royalty proceeds from a sale of royalties taken in kind by the Secretary; and (3) any other revenues from a specified bidding system.

Instructs the Secretary to: (1) pay 20% of the allocable share of each coastal state directly to certain of its coastal political subdivisions, (2) distribute a certain conservation royalty into the Land and Water Conservation Fund, and (3) distribute 50% of federal royalty revenues from areas leased under this Act into direct federal deficit reduction.
