EPA Seeks Comments on Draft
Underground Injection Permit

Core Energy, LLC

Otsego County, Michigan

The U. S. Environmental Protection
Agency plans to allow Core Energy,

LLC, 1011 Noteware Drive, Traverse
City, MI 49686 to inject fluid
underground by approving the
company's application for what EPA
calls a Class II injection well permit.

If EPA makes its approval final,

Core Energy, LLC may inject
Carbon Dioxide into a rock
formation 5744 feet below the
surface through a well at NE !4 ,

Section 21, T30N, R2W, Otsego
County, Michigan. Core Energy,

LLC has also applied for a permit
from the Michigan Department of
Environmental Quality (MDEQ).

EPA is accepting comments from the public on this proposed permit approval
(see box, left). The public comment period, which ends June 25, 2018 includes
30 days for comments as required by law, plus an additional three days for any
delay caused by mailing.

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 significant comments.

The Safe Drinking Water Act requires EPA to regulate the underground
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 Regulations, Parts 144 and 146.

EPA does not have the authority to change the surface location of the injection
well. If you have questions or concerns about the well's location, contact the
MDEQ, P.O. Box 30256, Lansing, Michigan 48909 and phone number (517)
284-6826.
