(4) Compatibility of injected fluids with formation fluids; and

b. If the receiving strata is not a water-bearing formation, the fracture pressure in the production zone;

14. The procedures to ensure that installing recovery, injection, and monitoring wells will not result in hydraulic communication between the production zone and overlying or underlying stratigraphic horizons;

15. The procedures used to verify that the injection and production wells are in communication with monitoring wells completed in the receiving strata and employed for the purpose of detecting excursions;

16. The well construction method must be stated in the permit application. Descriptions of the construction and completion details for all injection and production wells in accordance with sections 43-02-02.2-25 through 43-02-02.2-27, and for monitoring wells in accordance with sections 43-02-02.2-25, 43-02-02.2-26, and 43-02-02.2-28;

17. A schedule for and description of the procedures to demonstrate and maintain mechanical integrity of all injection and production wells in accordance with section 43-02-02.2-30;

18. A corrective action plan in accordance with section 43-02-02.2-33 for wells that are improperly sealed, completed, or abandoned, consisting of the steps or modifications necessary to prevent movement of fluid into unauthorized zones;

19. A description of the proposed mining solution and the chemical reactions that may occur during mining as a result of injecting the mining solution;

20. A subsidence analysis, using established geotechnical principles, that estimates, based upon the proposed mining operation, the effect of subsidence upon the land surface and overlying aquifers;
