CHAPTER 331UNDERGROUND INJECTION CONTROL
SUBCHAPTER GCONSIDERATION PRIOR TO PERMIT ISSUANCE
RULE §331.122Class III Wells

The commission shall consider the following before issuing a Class III Injection Well or Area Permit:

  (1) all information in the completed application for permit;

  (2) all information in the Technical Report submitted with the application for permit, including the following:

    (A) a map showing the injection well(s) and area for which the permit is sought and the applicable area of review. Within the area of review, the map must show the number, or name, and location of all existing producing wells, injection wells, dry holes, surface bodies of water, mines (surface and subsurface), quarries, public water systems, 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 on this map. If production area authorizations are required prior to the commencement of mining, the proposed production areas must be shown on the map;

    (B) a tabulation of reasonably available data on all wells within the area of review which penetrate the proposed injection zone. This 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 executive director may require;

    (C) maps and cross-sections indicating the vertical and lateral limits of those aquifers within the area of review that contain water with less than 10,000 milligrams per liter of total dissolved solids, their position relative to the injection formation, and the direction of water movement;

    (D) maps and cross-sections, detailing the geologic structure of the local area;

    (E) generalized map and cross-sections illustrating the regional geologic setting;

    (F) proposed operating data:

      (i) average and maximum daily rate and volume of fluid to be injected;

      (ii) average and maximum injection pressure;

      (iii) source of the injection fluids; and

      (iv) analysis, as needed, of the chemical, physical, and radiological characteristics of the injection fluids;

    (G) proposed formation testing program to obtain an analysis of the physical, chemical, and radiological characteristics of the receiving formation;

    (H) proposed stimulation program;

    (I) proposed operation and injection procedure;

    (J) engineering drawings of the surface and subsurface construction details of the system;

    (K) plans (including maps) for meeting the minimum monitoring requirements of the rules;

    (L) expected changes in pressure, native fluid displacement, direction of movement of injection fluid;

    (M) contingency plans to cope with all shut-ins or well failures so as to prevent the migration of contaminating fluids into fresh water;

    (N) the corrective action proposed to be taken under §331.44 of this title (relating to Corrective Action Standards); and

    (O) the permit range table required under §305.49(a)(10) and §331.82(e)(7) of this title (relating to Additional Contents of Application for an Injection Well Permit; and Construction Requirements);

  (3) whether the applicant will assure, in accordance with Chapter 37, Subchapter Q of this title (relating to Financial Assurance for Underground Injection Control Wells), the resources necessary to close, plug, or abandon the well;

  (4) the closure plan, in accordance with §331.46 of this title (relating to Closure Standards), submitted in the Technical Report accompanying the application; and

  (5) any additional information reasonably required by the executive director for the evaluation of the proposed injection well or project.
