Section 74:29:11:02 - Application content requirements - Additional baseline information required

In addition to the requirements of §§ 74:29:02:07 and 74:29:02:11, the following information is required for an in situ leach mine permit:

(1) Ground water baseline information, including:

(a) A geochemical, lithological, and mineralogical description of the receiving strata and any aquifers that may be affected by the injection of mining solution;

(b) Aquifer characteristics for the water saturated portions of the receiving strata and aquifers that may be affected by the mining process. Characteristics may include aquifer thickness, velocity and direction of ground water movement, storage coefficients or specific yields, transmissivity or hydraulic conductivity, and the directions of preferred flow under hydraulic stress in the saturated zones of the receiving strata. The extent of hydraulic connection between the receiving strata and overlying and underlying aquifers and the hydraulic characteristics of any influencing boundaries in or near the proposed production areas shall be determined and described;

(c) The volume and areal extent of ground water anticipated to be influenced by the injection activities. The area of review shall include the area within a one-quarter mile radius of the injection wells, or as determined by the department;

(2) For uranium in situ leach mines, site-specific background radiological data including the results of measurements of radioactive materials occurring in important species, soil, air, and in surface and ground waters that could be affected by the proposed operations. The applicant shall develop a preoperational environmental radiological monitoring plan that must be approved by the department. The plan shall include a radiation survey of proposed mine facilities area, to include process or recovery facility, ponds, impoundments, and wellfields, that can be used as comparison to the radiation survey to be done at the time of mine closure as required in § 74:29:11:53;

(3) Unstable/seismic areas;

(4) A list and map of all adjudicated and permitted surface and ground water water rights;

(5) A list and map of all known existing water wells, producing wells, injection wells, abandoned wells, and exploration holes, giving location, depth, producing intervals, type of use, condition of casing, plugging procedures and date of completion for each well or drill hole within the permit area and on adjacent lands to the extent such information is available in public records and from a reasonable inspection of the property;

(6) Climatic data, including source and location data;

(7) Current land use and zoning within a one-mile radius of the mine permit boundary; and

(8) A list of occupied dwellings within a one-mile radius of the mine permit boundary.

The department may require presubmission meetings to discuss the procedures for baseline data and site characterization.
