020-19 Wyo. Code R. §§ 19-2 - Required Studies

(a) In addition to other information required by the Act and these regulations, all surface coal mining permit applications shall contain:

(i) A determination of the projected result of proposed surface coal mining and reclamation operations, both on and off the mine site, which may reasonably be expected to change the quantity or quality of the surface and groundwater; the surface and groundwater flow, timing and availability, the surface and groundwater quality under seasonal flow conditions, including dissolved and suspended solids; the effect of acid-forming and toxic material on surface and groundwaters; the stream channel conditions; and the aquatic habitat in the permit area and other affected areas. This information shall be in sufficient detail to enable the Administrator to determine the probable cumulative hydrologic impacts on surface and groundwater systems including the impacts resulting from the proposed operation and their interaction with the impacts of all anticipated mining upon all affected hydrologic systems. Anticipated mining shall be projected over the life of the operation, and shall include all other existing coal mining operations, any proposed coal mining operation for which a permit application has been filed and all proposed operations required to meet diligent development requirements for leased federal coal where mine development and geological information is available. The assessment of the probable cumulative hydrologic impacts shall be sufficient to make the determination of W.S. § 35-11-406(n)(iii).

(ii) Unless determined in writing by the Administrator to be unnecessary, a statement of the physical and chemical analyses of test borings or core samplings from the permit area of the coal seam, overburden, and stratum lying immediately under the coal seam to be mined, including logs of the drill holes and thickness and sulfur content of any coal seam.
