The Department of Environmental Quality proposed to amend Utah Admin. Code r. 307-401-9. The rule would exempt sources from the requirement to obtain an Approval Order if their greenhouse gas emissions are below the thresholds established by U.S. EPA. There will be a public hearing on October 7, 2010, and the last day to submit comments is October 15. http://www.rules.utah.gov/publicat/bull_pdf/2010/b20100915.pdf pp. 13-15.
