Hyperion Energy Center

An architect's rendering shows the proposed Hyperion Energy Center, a $10 billion oil refinery and power plant proposed for a rural site in Union County, S.D.

UPDATE: The South Dakota Board of Minerals and Environment today Sept. 15 granted a revised air quality permit for the Hyperion Energy Center.

The meeting in Pierre began this morning with the five-member listening to closing arguments from lawyers representing the developer of the proposed oil refinery and power plant in Union County and environmental groups opposed to the $10 billion project.

The draft permit, recommended by Department of Environment and Natural Resources staff, addresses new federal limits on greenhouse gas emissions, and new ambient air quality standards for nitrogen oxide and sulfur dioxide, "Hyperion officials hoping for final decision."

In addition, the board will decide whether to approve Hyperion's request to extend the deadline for starting construction of the refinery just north of Elk Point, which would process 400,000 barrels of Canadian tar sands crude oil each day into low-sulfur gasoline, diesel, jet fuel and liquid petroleum gas.

Hyperion's original permit, approved by the board in August 2009, called for construction to begin by February of this year. The Dallas, Texas-based company wants the permit changed to give it until 18 months from now to start construction.
