Development of Northern Great Plains coal resources will create new demands for State and local government services. Development will also produce increased government revenues. Special taxes on coal production have been enacted in Montana, North Dakota, and Wyoming in order to insure that State and local governments receive sufficient revenues to finance the new services required. This study reports detailed estimates of the State and local taxes that would be paid by three different sized coal mines and their employees in Montana, North Dakota, South Dakota, and Wyoming. The estimates were obtained by using the ENERGYTAX simulation model.
