BISMARCK, N.D. (AP) — North Dakota regulators have approved a $150 million expansion of a natural gas processing plant in McKenzie County.

The Wild Basin Gas Plant is in the most prolific part of the Bakken oil patch in northwestern North Dakota. It currently can process about 80 million cubic feet of natural gas per day. The project will expand that to 280 million cubic feet daily.

It will be the largest natural gas processing complex in the state. Public Service Commission Chairman Randy Christmann says it's "one of the biggest steps ever taken in North Dakota to decrease flaring" of excess natural gas.

The three-member PSC on Wednesday approved the project planned by Oasis Midstream Services about 6 miles northeast of Watford City.
