-14- 2. THE PERMITTEE WILL SAMPLE SITES SWl through 10 TWICE YEARLY, ONCE DURING SPRING MELT AND ONCE DURING A STORM EVENT. SITES WILL HAVE FIELD PARAMETERS TESTED WITH FLOW DESCRIBED. CHEMICAL ANALYSES WILL BE SUBMITTED FOR EACH SITE WITH FLOW. THE PERMITTEE WILL SUBMIT ALL SURFACE WATER DATA ANNUALLY TO THE DIVISION. 3. THE ALLUVIAL WELLS MW1-3, WILL CONTINUE TO BE MONITORED MONTHLY FOR WATER LEVEL, pH, EC, AND TEMPERATURE. THE FULL CHEMICAL SUITE AS PREVIOUSLY SUBMITTED WILL BE ANALYZED SEMI-ANNUALLY; ONCE DURING SNOWMELT AND ONCE DURING A RAINFALL EVENT. THIS INFORMATION WILL BE COMPILED BY THE PERMITTEE AND SUBMITTED TO THE DIVISION ON AN ANNUAL BASIS. With the acceptance of the above stipulations, the operation is in compliance with the requirements of this section. VI. Ground Water Hydrology - Rules 2.04.5, 2.04.7, 2.05.3(4), 2.04.5(3) ana 4.05 The ground water information within the permit application is found in Section II-E. A description of ground water occurrences and mining impacts within the permit and adjacent areas can be found in Section IX - "Probable Hydrologic Consequences of Mining and Cumulative Hydrologic Impact Study" of this document. Due to the increased reactive surface area of spoil material, there is the possibility that ground water seeping from the reclaimed pits at the Grassy Gap Mine will be of poor quality and may detrimentally impact the water quality of the permit and adjacent areas. The applicant proposes to drill three ground water monitoring wells into reclaimed Pits 2 and 5 and one at the base of Pit 4 when reclaimed. These wells will supply needed information on changes in ground water quality in the compacted spoil at these pits. The applicant has submitted the information needed to determine if the spoil in these pits is representative of the material in Pits 1, 3, and 6. Therefore, it is possible to project the results of the monitoring of Pits 2, 4, and 5 to the other pits. The following stipulation is required to insure timely and proper installation of these monitoring wells. Stipulation No. 4: THE PERMITTEE WILL PLACE GROUND WATER MONITORING WELLS IN RECLAIMED PITS 2 AND 5. THESE WELLS WILL BE COMPLETED DOWN TO BEDROCK AND LOCATED ON THE RESPECTIVE DOWNDIP SIDES OF THE PITS. THE PERMITTEE WILL HAVE THE LOCATIONS OF ALL WELLS APPROVED BY THE DIVISION BEFORE DRILLING AND IMPLACEMENT OF MONITORING EQUIPMENT. ACCEPTABLE PLANS MUST BE SUBMITTED WITHIN 1 MONTH OF PERMIT ISSUANCE AND THE WELLS MUST BE INSTALLED DURING THE 1984 CONSTRUCTION SEASON. WELL COMPLETION DIAGRAMS WILL BE SUBMITTED TO THE DIVISION WITHIN ONE MONTH OF COMPLETION. THESE WELLS WILL BE TESTED QUARTERLY FOR FIELD PARAMETERS AND CHEMICAL PARAMETERS. THE RESULTS WILL BE SUBMITTED TO THE DIVISION ON AN ANNUAL BASIS.
