1200-4-6-.05(1) resulting from any failure of the well or associated equipment. 

9. Plugging and Abandonment Plan – Submit Plugging and Abandonment Plan 

that meets the Standards and Requirements of Rule 1200-4-6-.09(6), (7), (8) 

and (9). This plan shall also contain a detailed cost estimate for plugging and 

abandonment. 

10. Financial Responsibility – Submit a surety bond or other evidence of 
 financial responsibility as required by Rule 1200-4-6-.09(10). 

 

11. Provide a statement that the proposed Class II well will be completed in 

such a manner to insure that the injected substances are injected into the 

proposed injection zone and that provisions have been made for adequate 

protection of formation(s) containing ground water classified pursuant to Rule 

1200-4-6-.05(1) and any other zone of commercial value. This statement 

should contain a brief summary of the information contained in the application 

attachments that verify that injection only occurs in the injection zone and that 

adequate protection for ground water classified pursuant to Rule 1200-4-6-

.05(1) is provided. 

B. Enhanced Recovery Operational Permits 

1. General Information – Submit information equivalent to that in I.A. 

1-11 of this Application Attachments Guidance. 

2. Reservoir Description – Applications for Class II enhanced recovery 

wells must also include a description of the reservoir to be enhanced and a 

statement relative to the necessity for the use of wells to enhance production of 

oil or natural gas. This reservoir description is in addition to the Area of 

Review Description, but may make reference to portions of the description of 

the area. 

C. Hydrocarbon Storage Operational Permits 

1. General Information – Submit information equivalent to that in I.A. 

1-11 of this Application Attachments Guidance. 

2. Reservoir Map – Submit a map showing the known areal extent of the 

reservoir to be used for storage and the locations of all wells or test holes 

known to extend into or through the proposed reservoir. 

3. Geologic Information – Submit a series of maps and geologic cross- 
Sections showing the known subsurface position and structure of the reservoir, 

the nature of the horizontal and vertical boundaries of the reservoir, and the 

thickness of the reservoir. 

4. Existing Well Information – Submit a tabulation of the type, 

construction, depth, and current condition of each well or test hole located 

within the area covered by the reservoir map described in I.C. 

2 of this Application Attachments Guidance. 

5. Plugging Plan – Provide a detailed description of the procedures to be used to 

plug or work over the existing reservoir wells or test holes to prevent migration 

of injected substances into any aquifer other than the proposed storage 

reservoir. 

6. Reservoir Integrity – Provide detailed description of the method, procedures, 

and devices for testing the integrity or the proposed reservoir to contain the 

injected substances within the bounds of the reservoir. 

II. Area Permits

If an Area Permit is sought for Class II activities, submit information, in an area context, 

equivalent to that described in I.A., B., or C. of this Applications Attachments Guidance. 

However, in providing this information, the following must be provided or addressed in 

area permit application attachments: 

A. The “Area of Review Description” for Class II area permits must also provide 

Sufficient information for the Department to define the area within which the 

injections will be authorized by the area permit. 

B. The information described in I.A., B., or C. of this Attachments Guidance regarding 

Construction, monitoring, reporting, operation, and abandonment must be provided 

for each injection well in the proposed area. However, wells with equivalent 

construction, monitoring, reporting, operation, and abandonment characteristics 
may be grouped together in the application and a single description of the 

information required for each of these topics will suffice. 

C. Each injection well in the field must be accurately located on the map described in I 

I.A. 2 (Corrective Action) of this application attachments guidance. 

D. Documentation that each injection well is in the same well field, facility site,

E. Documentation that the waste to be injected at each well is not hazardous. 

F. Documentation that every injection well in the field will be operated by the same 

owner or operator. 

III. Plugging and Abandonment Permits

Attachments to all Class II Plugging and Abandonment permit applications, whether for 

an individual well or for an area, must contain the following: 

A. A summary of the reasons for abandonment. 

B. An updated copy of the previously approved plugging and abandonment plan with 

any plan modifications deemed necessary. 

C. Current evidence of financial responsibility.
