Section 7102-67.0 - Information to be considered by the Department

67.1 This Section sets forth the information which shall be considered by the Department in authorizing Class I wells or Major Class V wells. For an existing or converted new Class I or Major Class V well, the Department may rely on the existing permit file for those items of information listed below which are current and accurate in the file. For a newly drilled Class I or Major Class V well, the Department shall require the submission of all the information listed below. For both existing and new Class I or Major Class V wells, certain maps, cross-sections, tabulations of wells within the area of review and other data may be included in the application by reference provided they are current, are readily available to the Department and to the Applicant or Permittee, and are sufficiently identified to be retrieved.

67.2 Prior to the issuance of a permit for an existing Class I or Major Class V well to operate or the construction or conversion of a new Class I or Major Class V well the Department shall consider the following:

67.2.1 Information required in Section 32.0;

67.2.2 A map showing the injection well(s) for which a permit is sought and the major area of review. Within the area of review, the map must show the number, or name, and location of all production wells, dry holes, surface bodies of water, springs, mines (surface and subsurface), quarries, water wells and other pertinent surface features including residences and roads. The map should also show faults, if known or suspected. Only information of public record is required to be included on this map;

67.2.3 A tabulation of data on all wells within the area of review which penetrate into the proposed injection zone. Such data shall include a description of each well's type, construction, date drilled, location, depth, record of plugging and completion, and any additional information the Department may require;

67.2.4 Maps and cross-sections indicating the general vertical and lateral limits of all underground sources of drinking water within the area of review, their position relative to the injection formation and the direction of water movement, where known, in each underground source of drinking water which may be affected by the proposed injection;

67.2.5 Maps and cross-sections detailing the geologic structure of the local area;

67.2.6 Generalized maps and cross-sections illustrating the regional geologic setting;

67.2.7 Proposed operating data:

67.2.7.1 Average and maximum daily rate and volume of the fluid to be injected;

67.2.7.2 Average and maximum injection pressure; and

67.2.7.3 Source and an analysis of the chemical, physical, radiological and biological characteristics of injection fluids;

67.2.8 Proposed formation testing program to obtain an analysis of the chemical, physical and radiological characteristics of and other information on the receiving formation;

67.2.9 Proposed stimulation program;

67.2.10 Proposed injection procedure;

67.2.11 Schematic or other appropriate drawings of the surface and subsurface construction details of the well.

67.2.12 Contingency plans to cope with all shut-ins or well failures so as to prevent migration of fluids into any underground source of drinking water;

67.2.13 Plans (including maps) for meeting the monitoring requirements in subsection 66.2;

67.2.14 For wells within the area of review which penetrate the injection zone but are not properly completed or plugged, the corrective action proposed to be taken under Section 47.0;

67.2.15 Construction procedures including a cementing and casing program, logging procedures, deviation checks, and a drilling, testing, and coring program; and

67.2.16 A certificate that the applicant has assured, through a performance bond or other appropriate means, the resources necessary to close, plug or abandon the well.

67.3 Prior to granting approval for the plugging and abandonment of a Class I or Major Class V well the Department shall consider the following information:

67.3.1 The type and number of plugs to be used;

67.3.2 The placement of each plug including the elevation of the top and bottom;

67.3.3 The type, grade and quantity of cement to be used;

67.3.4 The method for placement of the plugs; and

67.3.5 The procedure to be used to meet the requirement of Section 63.0 .
