miles, down-gradient of the affected lands. On a sitespecific basis, the Boazd or Office may extend the distance beyond two (2) miles down stream. (b) Submit surface water quality and flow data collected during a minimum of five (5) successive calendar quarters and such other additional data, or a period specified by the Office, as may be 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 success, and to insure the adequacy of environmental protection facility design, maintenance and operation. Where surface water samples are not available during the specified time period due to climatic condition, the Office must be contacted so that other alternatives may be agreed upon. (c) Analytical detection limits for surface water must be acceptable to the Office for surface water quality pazameters in consultation with the Water Quality Control Division. (12) Water Quality Monitoring Plan -where necessary to demonstrate that the Environmental Protection Plan requirements are being met, a water quality monitoring plan shall be proposed for both surface and groundwater. The intent of the proposed water quality monitoring plan shall be to demonstrate that all environmental protection facilities designed to protect water quality are functioning as designed and whether the operation is in compliance with all applicable surface water and groundwater standards and Pernut conditions. Where a Colorado Discharge Permit System (CDPS) discharge permit exists or has been applied for, such pemut maybe adequate to satisfy the requirements of this Subsection. (13) Climate - on a case-bycase basis, the Environmental Protection Plan shall: (a) provide adequate climatic data representative of the site to perform an acceptable "water balance" for all liquid containment systems open to the environment and intended to contain designated chemicals or acid mine drainage, and demonstrate that the amount of evaporation required to maintain reserve facility capacity will occur, or that there is sufficient reserve capacity to compensate for the uncertainty associated with the data. (b) Provide the following information regazding climatic factors, above six thousand five hundred (6500) feet of elevation, (with the approval of the Office, data maybe provided from existing stations within the vicinity of the Permit azea): (i) the mean annual precipitation for a minimum of five (5) yeazs and, where available, one set of data for the wettest year on record for the azea; (ii) the average direction and velocity of the prevailing winds; (iii) the mean monthly temperature and temperature ranges for a minimum of five (5) years; (iv) on a case-by-case, site-specific evaporation and sublimation rates for the proposed site. (c) For operations below elevations of six thousand five hundred (6500) feet, provide the above data covering a period of one yeaz. (14) Geochemical Data and Analysis -include appropriate geochemical evaluations of any material that will be exposed by mining, placed in on-site solution containment systems or facilities, stockpiled, or disposed of on the affected land, and that has the potential to cause acid mine drainage or to release designated chemicals, or toxic or acid-forming materials.
