Intrepid Technology and Resources, Inc. (IESV) announces that the Idaho Department of Environmental Quality has provided written concurrence that the Whitesides Biogas Facility meets the permit to construct exemption requirements of Idaho rules for the control of air pollution. Intrepid submitted an exemption request based on calculations and modeling of air emissions for the plant. To the company’s knowledge, no other dairy digester system has produced the emissions modeling to receive an exemption. Two compounds of sulfur in digester emissions, hydrogen sulfide and sulfur dioxide, are regulated under the Clean Air Act. The Whitesides Biogas facility has sulfur removal equipment that provides a competitive edge in an area where emissions, and compliance to clean air requirements, is a growing concern. Future, larger digester projects may require an air permit, but the groundwork established in the DEQ review of the Whitesides data will aid the company in the preparation of those permits. [ more ]
