Section 312IAC16-5-16. Corrective action to wells affected by a Class II well

   (a) This section applies if the survey required under 312 IAC 16-3-2(f) locates a well that penetrates:

(1) the injection zone to be utilized by the new injection well; or

(2) a formation that will be affected by the increase in pressure resulting from operation of the new injection well, where the well located by the survey is improperly sealed, constructed, or abandoned.

  (b) If this section applies, an applicant shall submit a plan consisting of steps or modifications needed to prevent the movement of fluid into an underground source of drinking water. The plan shall be developed by the owner or operator, and evaluated by the director, based upon the following:

(1) The nature and volume of injected fluid.

(2) The nature of native fluids or byproducts of injection.

(3) Potentially affected persons.

(4) Geology.

(5) Hydrology.

(6) History of the injection operation.

(7) Completion and plugging records.

(8) Abandonment procedures in effect when the well was abandoned.

(9) Hydraulic connections with an underground source of drinking water.

  (c) The division director will evaluate the corrective action plan based on its adequacy to assure that wells within a one-fourth (¼) mile radius will not serve as a conduit for the migration of fluids into an underground source of drinking water.

  (d) Upon approval by the division director of a plan submitted under subsection (b), the plan is incorporated as a condition of the permit for the new injection well.
