within the existing or proposed affected azea where such subsurface materials and any associated waters have the potential to be contaminated by designated chemicals used in the extractive metallwgical process or by materials that aze toxic oracid-forming, or that produce acid mine drainage; (d) identify and locate on a map, in Exhibit C, known major fracture systems that affect rock formations under proposed sites of material storage, stockpiles, waste piles, disposal sites, solution containment facilities and other sites within the existing or proposed affected (land) azea where such fractwes and any associated waters have the potential to be contaminated by toxic or acid-forming materials or designated chemicals used in extractive metallwgical process or that produce acid mine drainage; and (e) describe and illustrate the hydrogeology of the azea where surface or groundwater maybe impacted by the Designated Mining Operation activities. Include in the description and illustrafion, those geologic strata and fractwe systems that have the potential to transmit groundwater. (9) Groundwater Quality Data - (a) Indicate the existing and reasonably potential futwe groundwater uses on and within two (2) miles down-gradient of the affected lands. The required information may further be limited to that azea which can also be demonshated by the Operator to lie within the local ground and surface water regimes that include the affected ]ands. On aaite-specific basis the Office or Boazd may extend the distance beyond 2 miles. (b) Submit, at a minimum, groundwater quality data collected during five (5) successive calendaz quarters or as specified by the Division, as maybe necessary to adequately characterize baseline conditions. This baseline data shall be sufficient to provide for the proper design of facilities, to serve as a basis for the evaluation of reclamation performance standards, and to enswe the adequacy of Environmental Protection Facility design, maintenance and operation. (c) Analytical detection limits and groundwater quality parameters must be acceptable to the Office. (10) Swface Water Control and Containment Facilities Information (a) Provide design specifications certified by a licensed professional engineer for all Environmental Protection Facilities intended to: (i) hold, convey, contain, or transport designated chemicals used in the extractive metallwgical process; (ii) convey, transport or divert Swface water around or away from acid mine drainage or toxic or acid-forming material; or (iii) captwe and/or retain surface water run-off from areas affected by the Designated Mining Operation prior to its release from the mine-site into the natural water drainage system. (b) Submit a Storm Water Management Plan, if required by the Water Quality Control Division, including a copy of such plan and a maintenance and inspection program to enswe all drainage control and containment facilities will be properly operated and maintained. (11) Swface Water Quality Data- (a) Indicate the existing surface water receiving stream standazds, existing or reasonably potential futwe uses of surface water and, where receiving stream standards have not been determined, within two (2)
