S. Environmental Protection Agency has tentatively approved the reissuance of a Class I nonhazardous injection well permit for Cooper Standard Automotive. Before EPA makes a final decision, the Agency is providing the public an opportunity to comment on the draft permit (see left-hand box on how to comment). Cooper Standard Automotive plans to continue to dispose of nonhazardous liquid waste at its facility in Otsego County at 594 Alpine Hill Road, Gaylord, Michigan. The injection fluid consists of contaminated groundwater purged from the Glacial Drift aquifer at the facility and will be injected into a confined interval approximately 2300 feet below ground surface. Federal law requires all Class I wells be built in a way that protects drinking water supplies.1 That means waste must be injected into a rock formation beneath the lowermost formation containing an underground drinking water source. All Class I wells shall be cased and cemented to prevent the movement of fluids into or between underground sources of drinking water.

The public comment period includes 30 days for comments as required by law, plus an additional three days for any delay caused by mailing. Requests for a hearing must be in writing and must identify issues to be raised. EPA will hold a hearing if there is significant public interest in the draft permit decision based on written requests. If a hearing is scheduled, EPA will publish a notice of the hearing at least 30 days in advance. EPA will consider all comments received during the comment period and the hearing if held and then issue a final decision along with a document that lists EPA responses to significant comments. Permit Requirements Federal regulations for underground injection wells list standards for construction, geology, location (siting), operating conditions, and record keeping, to protect supplies of underground drinking water from contamination caused by injection wells. EPA's preliminary review of the permit application for this well concluded it would have no environmental impact. Below is an explanation of the some of the factors involved in permitting an injection well: Underground Source of Drinking Water (USDW): A USDW is defined as any aquifer or portion thereof that contains less than 10,000 milligrams per liter of total dissolved solids and which is being or can be used as a source of drinking water. In the case of the Cooper Standard Automotive well, the base of the lowermost USDW has been identified at a depth of 825 feet below the ground surface. This water- bearing formation is the Glacial Drift Site Geology: The injection zone is the Dundee Limestone and the Detroit River Group at depths between 2300 feet and 2648 feet below the surface. The immediate overlying confining zone is the Bell Shale. Additional adequate confining layers exist between the injection zone and the base of the lowermost Underground Source of Drinking Water. Area of Review (AOR): The AOR is the area within a two-mile radius of the proposed injection well. EPA analyzed the AOR to identify wells that might allow fluid to move out of the injection zone. In the AOR for the proposed well, there are approximately 5 producing, 4 injection, 0 temporarily abandoned, 30 plugged and abandoned, and 0 other wells that penetrate the injection zone. EPA review determined that wells in the AOR are adequately constructed to prevent injected fluid migration from the injection zone to the USDW. Maximum Injection Pressure: EPA set an injection pressure limit that will prevent the injection formation from fracturing. The proposed maximum injection pressure for this well is limited to 700 pounds per square inch. Financial Assurance: Cooper Standard Automotive, has demonstrated adequate financial resources to close, plug and abandon this underground injection well. Cooper Standard Automotive, has established surety bond to cover these costs at the amount of $30,000. ------- |
