Mr. Emerson J. Addison, Dr. Ronald J. Kruske, D.D.S., Ms. Amy Kruske, and Ms. Jennifer Springstead each petition the Environmental Appeals Board (“Board”) to review an Underground Injection Control (“UIC”) Class II permit that the U.S. Environmental Protection Agency Region 5 (“Region”) issued to Jordan Development Company, L.L.C. (“Jordan”) in October 2018. The permit authorizes Jordan to convert an existing oil production well in Gladwin County, Michigan, for injection of brine, a byproduct of oil and natural gas drilling activities.
