The U. S. Environmental Protection Agency plans to modify two existing
permits for Environmental Geo-Technologies, LLC, 28470 Citrin Drive,
Romulus, Michigan, 48174 to inject waste fluid underground. The company's
existing permits are for two wells located in Wayne County. EPA previously
issued permits for this activity in 2011. The proposed modifications will limit
allowed fluids and increase reporting requirements (see page 2).
EPA is accepting comments from the public on this proposed permit
modification approval (see box, left). The public comment period, which ends
Tuesday, July 18, 2017, 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 until the permits expire.
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 in the
proposed modifications. 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 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.

"Monthly Reports"
Add "specific gravity" to the monthly reporting
requirements.

Change the maximum injection pressure from 765 to
968 pounds per square inch gage (psig).
Add a specific gravity limit of 1.10.
EPA limits injection pressure at the surface to control the hydraulic pressure that occurs within the
injection zone located between 3,937 and 4,550 feet below the ground surface. EPA calculated the current
maximum injection pressure limit of 765 psig using an injection fluid specific gravity of 1.22. The
anticipated pressure that the bottom of the injection zone experiences under the current permit limit of 765
psig is approximately 3,183 psi. Under the proposed limit of 968 psig and a specific gravity of 1.10, the
pressure at the bottom of the injection zone would be approximately 3,150 psi. This maximum injection
zone pressure is approximately 33 psi, or about 1% less than the pressure anticipated by the current
injection pressure limit. EPA is providing an additional protection to the injection zone by listing the
specific gravity of 1.10 as a permit limit. The current permits do not list a specific gravity limit. This new
specific gravity limit will prohibit injection of any fluid with a specific gravity greater than 1.10.
