EPA Seeks Comments on
Injection Well Permits
Sunoco Pipeline LP - Injection Wells
Wayne County, Michigan
April 2017
U. S. Environmental Protection Agency tentatively approved a request
from Sunoco Pipeline LP for three Class I nonhazardous injection well
pennits. Before EPA makes a final decision, the Agency is providing the
public an opportunity to comment on the draft permits (see left-hand box
on how to comment).
The Newtown Square, Pennsylvania-based company plans to dispose of
nonhazardous liquid waste from solution mining operations at its gas
storage facility. The company wants to drill and construct two injection
wells located at 7155 Inkster Road in Taylor, Michigan. Sunoco Pipeline
also operates an existing Class I nonhazardous injection well for which
they want a new permit.
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.

'Injection wells must meet the regulatory criteria of 40 Code of Federal
Regulations, or C.F.R., sections 124, 144, 146, and 147; and the Safe
Drinking Water Act, or SDWA. To view these regulations and laws, see

Public comments and requests for a
hearing
Send comments and requests for a hearing to EPA's
Jeffrey McDonald (mcdonald.ieffrev@epa.gov) during
the public comment period (see front-page box). The
dates of the public comment period are also published
in the News Herald newspaper in Wayne County. 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
decisions 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 applications for
these three wells concluded they would have no
environmental impact.
Below is an explanation of the some of the factors
involved in permitting injection wells:
Underground Source of Drinking Water (USDW):
An USDW is any aquifer or portion of an aquifer that
contains less than 10,000 milligrams per liter of total
dissolved solids and which can be used as a source of
drinking water.
An aquifer is an underground layer of water-bearing
rock or sand from which water can be extracted by a
well.
In the case of the Sunoco Pipeline proposed and
existing wells, the base of the lowermost USDW sits at
a depth of 308 feet. This water-bearing formation is the
Detroit River formation.
Site geology: The injection zone is the Franconia
Formation, Galesville Sandstone, Eau Claire
Formation, Mount Simon Sandstone, and Precambrian
crystalline basement from 3,856 feet to 4,579 feet
below the surface. The immediate overlying confining
zone includes the Black River, Glenwood, and
Trempealeau formations which are composed of
limestone, dolomite and shale. 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 each injection well. EPA experts
analyzed the AOR to identify wells that might allow
fluid to move out of the injection zone. In the AOR for
the three proposed wells, there are 0 producing, 2
injection, 0 temporarily abandoned, and 0 plugged and
abandoned wells that penetrate the confining zone.
These wells meet construction standards and will not
allow fluid to move out of the injection zone for the
proposed wells.
Maximum injection pressure: EPA set an injection
pressure limit that will prevent the injection formations
from fracturing. The proposed maximum injection
pressure for these wells is limited to 604 pounds per
square inch gauge for each well.
Financial assurance: Sunoco Pipeline LP has
demonstrated adequate financial resources to close,
plug and abandon these underground injection wells.
State bonds for $92,418 for Well # 1A, $91,870 for
Well # 2, and $91,870 for Well # 3, have been
established with the state of Michigan.
