Confirming the contentions of activists that Hyperion's permit for its proposed oil refinery in Elk Point, South Dakota was not complete, the company has petitioned the Hugh County Circuit Court to amend its state air quality permit.
Specifically, Hyperion is asking to make changes to the permit so it can control emissions of sulfur dioxide and nitrogen dioxide, air pollutants that were not adequately addressed in the original permit.
Additionally, Hyperion has to come up with a plan to address emissions from coker quench water tanks, which Hyperion previously stated were not a source of emissions.
Ed Cable, spokesperson for Save Union County, said:
The permit was not complete and accurate, and they're acknowledging there is one source of admissions that was not previously disclosed.
Global Community Monitor has been working with residents to stop the proposed 400,000 barrel a day new refinery from being built in the rich farming zone of southeast South Dakota. Last year, GCM worked with Save Union County to launch its first Bucket Brigade to document the clean air in this rural farming community and to establish a baseline to compare with dirtier air in communities where oil refineries have already been built.
The proposed Hyperion refinery is also of increasing concern because of its planned use of Canadian tar sands crude oil, a dirtier crude oil with greater climate change and human health impacts.
