(a) The permit application shall include a mine plan containing all information required by W.S. § 35-11-406(b)(i) through (ix) and (xi) through (xviii), and consistent with the applicable in situ technology.
(b) The mine plan shall include applicable parts of Land Quality Division - Coal, Rules and Regulations, Chapter 2, Section 5(a).
(c) A description of operations specific to in situ mining, to include, but is not limited to the following: - (i) A description of the proposed method of operation, including the following:
- (A) Injection and recovery rate, with the average and maximum daily rate and the volume of fluid and/or gas to be injected;
- (B) Injection and recovery pressures, with average and maximum injection pressures;
- (C) Proposed stimulation program;
- (D) Proposed injection and recovery procedure;
- (E) Expected changes in pressure and direction of movement of injection fluid;
- (F) Underground gasifier design, operation and maintenance; and
- (G) A description of chemical or physical reactions that may occur during mining as a result of injection or recovery fluid injection.
- (ii) The following information concerning the production zone shall be determined or calculated and submitted for new Class III wells or projects:
- (A) Where the production zone is in a receiving strata which is naturally water bearing:
- (II) Fracture pressure; and
- (III) Physical and chemical characteristics of the receiving strata fluids.
- (B) Where the receiving strata is not a water-bearing formation, the fracture pressure in the production zone.
- (iii) The procedure(s) to insure that the installation of recovery, injection, and monitor wells will not result in hydraulic communication between the production zone and overlying stratigraphic horizons.
- (iv) The procedures utilized to verify that the injection and recovery wells are in communication with monitor wells completed in the receiving strata and employed for the purpose of detecting excursions.
- (v) Descriptions of:
- (A) Completion details for all monitor wells; and
- (B) Detailed description of the typical proposed well completion for injection and recovery wells, as required by Section 8 of this Chapter.
- (vi) Details of a monitoring program and reporting schedule as required by Sections 15 and 16 of this Chapter, respectively.
- (vii) A schedule and procedures to check for mechanical integrity of Class III injection wells as required by Section 9 of this Chapter.
- (viii) A corrective action plan, for any wells which are improperly sealed, completed, or abandoned, consisting of such steps or modifications as are necessary to prevent movement of fluid into unauthorized zones as required by Section 19 of this Chapter.
- (ix) The composition of all known and anticipated wastes and procedures for their disposal, including disposal of any waste water generated during hydraulic fracturing.
- (x) Details of a program to monitor the quantity and quality of waters that may be affected by the operation from premining through release of bond, including a description of procedures and time schedules used to confirm excursions.
- (xi) A description of measures employed to prevent an excursion, and contingency plans to be implemented in the event of an excursion.
- (xii) An assessment of impacts that may reasonably be expected as a result of the mining operation to water resources and water rights inside the permit area and on adjacent lands, and the steps that will be taken to mitigate these impacts.
- (xiii) A subsidence analysis, using established geotechnical principles, which estimates based upon the proposed mining operation the effect of subsidence upon the land surface and overlying groundwater aquifers. Subsidence shall be planned and controlled to the extent that the values and uses of the surface land resources and the groundwater aquifers will not be degraded.
- (xiv) A maintenance plan to ensure:
- (A) Wells are sufficiently covered to protect against entrance of undesirable material into the wells;
- (B) The wells are marked and can clearly be seen;
- (C) The area surrounding each well is kept clear of brush or debris;
- (D) Monitoring equipment is appropriately serviced and maintained so the monitoring requirements of Section 16 of this Chapter can be met; and
- (E) Spill response and reporting plan.
