NEW TOWN, N.D. (AP) – Three Affiliated Tribes Chairman Marcus Levings says he and Gov. John Hoeven are signing a continuation of an oil and gas tax and regulatory agreement between the state and tribe.

Levings says a ceremony is planned Wednesday afternoon.

The tribe and state reached the accord in the spring of 2008. The agreement limits oil tax rates on Fort Berthold Reservation land, and spells out how the state and tribal governments will share oil revenues. Its goal is to enhance oil and gas exploration on the reservation.

Levings says the agreement is scheduled to expire this summer but will now be continued indefinitely.
