EPA Seeks Comments on Plan to Modify
an Existing Class II Injection Well Permit

Marysville Hydrocarbons, LLC

St. Clair County, Michigan	April 2018

The U. S. 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.
