Page 131 <br />Hazd Rock/Metal Mining Rule 6 <br />(e) Taking into consideration the nature of the chemicals and the <br />risk to human health, property and the environment, describe any release <br />response procedures, redundancies, and "backup" measures necessary, <br />appropriate, and EconomicaIly reasonable, to control, prevent and mitigate <br />releases of the designated chencals and toxic oracid-forming materials from <br />the containment facility outside the permit azea during mining and reclamation <br />operations. <br />(f) Demonstrate that containment facilities shall be of adequate <br />size to provide sufficient reserve capacity to prevent a release of designated <br />chemicals or toxic or acid-forming materials from design storm events plus <br />operational water volumes during worst case conditions as specified by the <br />Office. <br />(8) Groundwater Information - <br />(a) locate on a map, is Exhibit C, all tributary water courses, <br />wells, springs, stock water ponds, reservoirs and ditches, on the affected land <br />and on adjacent lands where such structures or waters are within two (2) <br />miles, of the existing or proposed affected lands. The required information <br />may further be limited to that area which can also be demonstrated by the <br />Operator to lie within the local ground and surface water regimes that include <br />the affected lands. On aaite-specific basis, the Office or Board may extend <br />the distance beyond two (2) miles; <br />(b) identify all known aquifers and related subsurface water <br />bearing fracture systems within two (2) miles of the affected lands. The <br />required information may further be limited to that azea which can also be <br />demonstrated by the Operator to lie within the local ground and surface water <br />regimes that include the affected lands. In addition, using available data or <br />information, when acceptable to the Office, provide the general direction and <br />_ rate of flow of groundwater in these aquifers-and-fracture systems. O¢a case-- - - <br />by-case basis, the Office may require hydrologic testing and analysis, where <br />available information is inadequate to descnbe or address potential impacts to <br />groundwater resources; <br />(c) describe all geologic media down to and including the upper <br />most aquifer under proposed sites of material storage, stockp>Zes, waste piles, <br />disposal sites, solution containment facilities and other sites within the existing <br />or proposed affected azea where such subsurface materials and any associated <br />
