FROM KELO-TV:
An oil refinery in Union County is one step closer to becoming reality. The South Dakota Board of Minerals and Environment unanimously approved the air permit for the $10 billion Hyperion Energy Center.
The board has heard from supporters and opponents of the refinery during recently held hearings. Both sides were there for the decision on the permit in Pierre as well.
Opponents say they plan to appeal the decision to the circuit court.
