Hyperion air permit comment period extended The Department of Environment and Natural Resources (DENR) announced it is extending the public comment period on the draft Prevention of Significant Deterioration preconstruction air quality permit for the proposed Hyperion Energy Center in Union County.�?  The department is extending the 30-day comment period by another 31 days.�? Under the extension, DENR must receive comments by close of business on Nov. 14. â�?�?While the public comment period for the draft air quality permit is still open, we have already received several letters and emails requesting the deadline for comments be extended,â�? said DENR Secretary Steve Pirner.�? â�?�?Therefore, DENR is acting now to grant those requests and extend the comment period by another 31 days.â�?�?  The proposed Hyperion Energy Center will include a 400,000 barrel per day refinery and an integrated gasification combined cycle power plant.�? The purpose of a Prevention of Significant Deterioration pre-construction air quality permit is to ensure that emissions from the proposed facility will not degrade the air quality beyond increments allowed by state and federal air quality regulations. The permit also ensures the air quality will continue to fully comply with all National Ambient Air Quality Standards that have been established to protect public health and the environment. DENR has made a copy of the complete Hyperion air quality permit file available on its Web site at http://www.state.sd.us/denr/hyperion.htm.�? For those without Internet access, the permit file is available for viewing at DENRâ�?�?s offices in Pierre or in the Akeley-Lawrence Science Center, University of South Dakota, 414 East Clark, Vermillion.�? Copies of DENRâ�?�?s draft permit can also be obtained by writing to DENRâ�?�?s Pierre office at 523 East Capitol, Joe Foss Building, Pierre, SD 57501, or calling Kyrik Rombough, DENR natural resources engineering director, at 605.773.3151. DENR will consider and address all comments timely submitted and issue a final permit decision within 30 days of the end of the public comment period. DENR will notify the applicant and each person who submitted written comments or requested notice of DENRâ�?�?s final permit decision, including notification of any changes to the permit based on the comments.
