-4- respect to irrigated agriculture, and a discussion of f1or: characteristics in the Raton Creek channel. 2. .~ narrative must also be provided which describes the extent of mining for tY~e life-of-the-mine. This narrative must also include a discussion of any drainages which will be undermined during the life-of-the-mine. Sufficient materials must be provided to determine whether any of these drainages can be considered alluvial valley floor within a three mile radius of the area affected by the mine workings. VIII. f9ater Rights and Replacement - Rules 2.04.7(3), 2.05.6(3)(a 2.07.6(2)(c) and 4.05.15 Deficiencies: 1. The applicant must identify all user rights to sources of ground ~:~ater and surface water which have been adjudicated within the area hydrologically adjacent to the permit area. 2. The applicant needs to supply alternative water supply information in accordance with Rv1e 2.04.7(3). The applicant should identify the extent to which operations may proximately result in contamination, diminution or interrup- tion of a source of water for domestic, agricultural, industrial, fish and wild- life, or other legitimate use. The applicant shall identify alternative sources of water supply or augmentation water that could be used to replace existing sources. 3. 'lhe applicant should identify the amount of water proposed to be consumed by the operation for drinking, sanitary, dust suppression, or process water. The source of the water also needs to be indicated. An es ti. mate should be made of the amount of makeup water that will be needed for the preparation plant. 4. A brief water balance discussion should be included which chaz'acterizes the rainfall, runoff, E.T., and recharge relationships (water involved in infiltra- tion, percolation, aquifer recharge, or interflow). 5. The operator should apply for and submit to the Division the NPDES Permit and Application obtained from the Colorado I~Jater 2uality Control Division. IX. lydrologic Balance: Cumulative Impacts - Rules 2.05.6(3) and 2.07.6(2)(c) Deli ci encies Z. The applicant should include a statement of the probable hydrologic consequences of rn.ining. The statement should dr_sc.ribe o11 an ticipatcd potential impacts resu].t- :irg from mining with reyard to surface and ground wate'z quality and quantity. For all probable impacts identified their significance to the local or regional hydrology should be indicated. She statement should include a discussion of the measures that will be ta};en to minimize these impacts. The statement should identify the duration of the probable impacts. An exarnple of a mine impact ~~ihich could be considered, is increased sediment yields from disturbed areas. The probability of the impact depends on the hydrologic and geologic conditions as well as the water balance at the mine.
