The board, through permit conditions, may authorize the department to approve proposed technical revisions to the injection well portion of an in situ leach mine without the requirement of a permit amendment. In addition to the list of technical revisions in § 74:29:03:16, in situ leach mine permit technical revisions may include the following:

1. (1) Correction of typographical errors;
2. (2) Modification of monitoring plan reporting requirements;
3. (3) Modification of quantities or types of fluids injected that are within the capacity of the facility as permitted and would not interfere with the operation of the facility or its ability to meet conditions described in the permit and would not change its classification;
4. (4) Well construction requirements;
5. (5) The addition of wells to the wellfield within the permit area if the requirements of § 74:29:11:20 are met;
6. (6) Modification of injection rates and pressures;
7. (7) Modification of a well repair, abandonment, plugging, or conversion plan; and

8. (8) Delay the plugging requirement of subdivision 74:29:11:18(4) for an unused well.

   In situ leach mine permit technical revision applications must comply with the procedural requirements of § 74:29:03:16, as applicable.

   The applicant or an interested person may appeal the decision of the department to the board by petitioning for a contested case hearing pursuant to chapter 74:09:01.
