ANWR is Federal land so the State has to negotiate with the Feds for a % of royalty.  Don't know if the Feds will also give the State the right to charge a Production Tax which is where the State really sticks it to the producer.  But in the Gulf of Mexico the Feds share a % of the Royalty with the States so there is no reason to believe they won't do the same for ANWR.  
As far as oil production destroying the wild life or environment, the stewards of the lands for the last 10,000 years managed to allow 5,000 caribou near Prudhoe Bay.  When the oil companies came and managed the lands the herds grew so that its over 60,000 today.  Who does a better job of managing the wild life and the environment.
