Duke Energy Seeks Major Changes
To Existing Injection  Well  Permits
                                    Duke Energy Indiana Inc.
                                    Owensville,  Ind.
                                               June 2009
          IN-051-11-0002,
          x-0003
This map shows the location of Duke Energy's existing underground injection wells.

Duke Energy Indiana Inc. of Plainfield has asked U.S. Environmental
Protection Agency Region 5 to approve major changes to its permits for
three existing non-hazardous Class I injection wells in Owensville.
Specific wording of the changes is shown in tables beginning on Page 2.

Based on its initial review of the request and appropriate provisions of the
Safe Drinking Water Act, EPA believes the changes would have no
significant environmental impact and intends to issue the permit
modifications. Federal regulations allow for public comments on Duke
Energy's request before any final EPA ruling. However, all other
conditions of the existing permits  remain in force and are not subject to
comment.

The three wells are known as WDW #1, #2 and #3. Duke Energy's permit
numbers are:
    •   IN-051-1I-0001
    •   IN-051-1I-0003
    •   IN-051-1I-0004

-------
If EPA receives no public comments that ask for
changes to the proposed modifications, the permit
modifications become effective when they are issued. If
there are public comments that request a change, EPA
will respond to the comments and then issue the final
permits. The modifications become effective 30 days
after they are issued.

Exact dates of the public comment period will be
published in the Princeton Daily Clarion. A public
hearing may be scheduled if EPA receives significant
written comments within 30 days after this notice is
published in the newspaper. EPA will publish a notice
at least 30 days prior to any public hearing.

Part C of the Safe Drinking Water Act mandates
regulation of the underground injection of fluids
through wells to protect the quality of underground
sources  of drinking water. The act requires EPA to
administer underground injection control programs in
states that do not have approved UIC programs. Indiana
does not have such a program for Class I injection
wells, so EPA is administering the permit program.
Technical Details
In accordance with the conditions set forth in 40 CFR 144.39(a) and 124.5(a), the following permit conditions are
proposed for modification in all three permits:

Page 12/Injection Pressure
Limitation
Page 13/Automatic
Warning and Automatic
Shut-off System
Page 13/Continuouus
Monitoring Devices
Page 14 & 15/Monthly
Reports
Page 15/Monthly Reports
Attachment A/Operating,
Monitoring and Reporting
Requirements
MODIFICATION
Add the sentence: "The instantaneous maximum surface pressure limit specified
in Part III(A) of this permit shall be adjusted as the instantaneous injection fluid
specific gravity varies in accordance with the calculation set forth in Part III(A)."
Add the sentence: "Whenever the maximum surface pressure limit is adjusted in
accordance with the calculation set forth in Part III(A), alarm and shut-down
pressures must be adjusted to the same extent."
Add requirement for continuous monitoring of specific gravity.
Add requirement to graph annulus/longstring casing pressure differential,
injection fluid specific gravity and computed instantaneous maximum injection
pressure and reformatted for clarity.
Reformat section D(l)(f)(2) as D(l)(g) for clarity.
Add reporting of specific gravity and revise justification for maximum injection
pressure with adjustments for changes in specific gravity. Add minimum value
for specific gravity.
The following additional change is proposed to be made to the permit for WDW #1:

MODIFICATION
Change maximum injection pressure from "1,821 psig" to "1,920
