Hyperion Energy Center - Air Quality Request for Extension
The existing PSD permit requires Hyperion to begin actual construction of the Hyperion Energy Center by February 20, 2011, unless Hyperion requests an extension of the construction deadline. On June 23, 2010, Hyperion submitted a request to extend the construction deadline. Hyperion requests the deadline be extended from February 20, 2011, to August 20, 2012.
DENR reviewed Hyperion extension request. In addition, DENR reviewed the new 1-hour nitrogen dioxide National Ambient Air Quality Standard, the new 1-hour sulfur dioxide National Ambient Air Quality Standard, the inclusion of coker quench water tank, a reanalysis of the Best Available Control Technology for the permitted equipment, and a new analysis for the Best of Available Control Technology for greenhouse gas emissions.
During the public comment period, the Department of Environment and Natural Resources (DENR) received comments from approximately 350 individuals, small businesses, environmental groups, the U. S. Environmental Protection Agency, the U.S. National Park Service, Hyperion, Tribes and others. DENR has reviewed and responded to those comments in a document that is approximately 80 pages long, and where appropriate, incorporated changes into the amended air quality permit based on those comments.
The Board of Minerals and Environment held a “Contested Case Hearing” on the amended air quality permit from July 25-28, 2011. The board granted the construction deadline request and issued a revised PSD permit on September 15, 2011.
In November 2011, Citizens Opposed to Oil Pollution, Save Union County, Sierra Club and Hyperion appealed the Board of Minerals and Environment’s decision. In February 2012, The Circuit Court affirmed the Board of Minerals and Environment’s decision.
