3. Other available: No other information for recorded water rights was available from published data. <br />4. Changes to drainage basins caused by operations on site: <br />There will be no significant and permanent changes in watershed boundaries caused by operations on site. As <br />discussed in the reclamation plan, mining will modify the existing drainages across the property and into the San <br />Juan River and Rio Blanco, but will not significantly impact flows or points of entry. <br />Other than disturbances in vegetation, area exposed to erosion, and evaporation, the only significant <br />change in drainage basin characteristics is the blocking of potential surface flows from pit and working areas during <br />the life of the pit and after reclamation, resulting in increased infiltration into the surficial alluvial deposits and <br />bedrock beneath the material being mined. The impact will be minimal, as less than 0.001 % of the total basin will be <br />blocked from discharging at any one time during mining and reclamation operations. <br />5. Aquifers and watersheds in this area: <br />The only recognized aquifer in the area is the Morrison Formation, approximately 500 feet below surface; the alluvial <br />aquifer associated with the Rio Blanco and San Juan River is potentially a significant source of water, but is not <br />expected to be impacted by operations, which are limited to 6640 feet, or more than 40 feet above the high water <br />mark of the San Juan River at this point. Construction and maintenance of the road, bridge, and pipeline, and use of <br />stockpiles, will not impact on the river or aquifer. However, river water may be useable for water for plant and pit <br />operations. Based on depths of existing wells in the area, there are no bedrock formations used as aquifers in the <br />area which will be mined which would be affected by the mining of the sand and gravel. The overburden (soil) and <br />the sand and gravel are not significant aquifers in this areas. Based on the location and depth of other known wells <br />in the area, the mining activities proposed will have no reasonable potential for any adverse impact. There will be no <br />blasting at this site. <br />6. Prevention and mitigation actions: <br />As discussed above, the area to be mined is at least 200 feet away horizontally, and 40 feet or more vertically, from <br />all bodies of water (rivers and Hams Ditch). There will be no planned surface discharge of storm water which has <br />come in contact with exposed stripped areas, mining areas, or stockpiles of extracted materials, waste materials, or <br />topsoil. As necessary, storm water pollution prevention and management actions, including erosion and <br />sedimentation control, will be implemented as required by the National Pollution Discharge Elimination System <br />and /or Colorado Discharge Permit System storm water general permit for which coverage has been obtained for this <br />site (prior to beginning mining), in case discharge is necessary. This meets the requirement for an NPDES permit <br />and covers dewatering and process (wash) water as well as storm water, and application has been made for <br />coverage. Since surface water flow will instead infiltrate into the bench's alluvial deposits at the west edge of pit and <br />reclaimed areas (along the top of the cliff) and is presumed to flow into the San Juan River as subsurface flows, no <br />net impact on river flow is anticipated. Overall design of the pit was done to plan for a minimum impact on surface <br />and ground water. Pit area is not being currently irrigated, nor is irrigation necessary for reclamation. <br />7. Prohibited actions necessary to protect water systems: <br />None known at this time, other than compliance with best management practices and specific items to protect the <br />irrigation ditch as listed above. Best management practices (BMP) forbid the discharge of heavily sediment -laden <br />waters and implementation of spill control and countermeasures actions to prevent discharge of a spilled substance. <br />The buffer zones are established for a variety of reasons, including protection of drainage, preservation of river <br />bottomlands, wildlife, neighbors, and prevention of downstream water degradation due to sedimentation. No <br />discharge of surface water is planned. The mining is planned to prevent negative impacts on ground and surface <br />water and to make maximum use of existing water resources in accordance with state water law. <br />6 Per conversations with Soil Conservation District personnel. <br />C &J Gravel Products, Inc.
