Environmental Protection Agency plans to modify what it calls a Class II permit for Marysville Hydrocarbons, LLC, 2510 Busha Highway, Marysville, Michigan. The existing permit for Well 1-7 BDW is used for salt water disposal located in St. Clair County, Michigan. EPA first issued a permit for this activity in 1990. The proposed modifications change the injection zone, the construction, and reduce the injection pressure (seepage 2). EPA is accepting comments from the public on this proposed permit modification approval (see box, left). The public comment period includes 30 days for comments as required by law, plus an additional three days for any delay caused by mailing. Only the conditions proposed for modification are re-opened for comment. All other aspects of the existing permit remain in effect. During the comment period, you may ask EPA - in writing - to hold a formal public hearing (see address, left). Be sure to say specifically what issues you want to raise. EPA will hold a hearing if there is significant interest. If there is a hearing, EPA will publish a notice at least 30 days prior. You will have an opportunity to make oral comments or submit written comments. EPA will consider all comments it receives, and then issue a final decision along with a response to the comments. The Safe Drinking Water Act requires EPA to regulate injection of fluids through wells to protect the quality of underground sources of drinking water. Issuing permits is one way EPA does this. You can find the regulations governing underground injection wells at Title 40 of the Code of Federal Map shows location of the injection wells 1-7 BDW and 2-7 BDW in St. Clair County, MI. ------- The proposed modifications are: PAGE/PERMIT CONDITION MODIFICATION Page 1 Change the permitted injection zone to the "Dundee, Lucas, Amherstburg, and Bois Blanc formations, and the Bass Island, Salina, Niagara, Burnt Bluff, and Cataract groups at depths between 631 and 2,953 feet" Page 12 - Part II (B)(3) Update the mailing address to "U.S. Environmental Protection Agency Region 5, Attn: UIC Branch, (WU-16J), 77 West Jackson Boulevard, Chicago, Illinois 60604-3590" Attachment A Change the maximum injection pressure from 1850 to 149 pounds per square inch gauge (psig) Attachment A Change the description of the maximum injection pressure calculation to read: "This limitation was calculated using the following formula: [{0.8 psi/ft - (0.433 psi/ft) (1.25)} x 631 feet] - 14.7 psi.
