-g- <br />schedule in Table 35 with the parameter list for sample analyses contained in <br />Table 4. Results of water quantity and quality monitoring at all designated <br />monitor sites will be submitted to the Division on a quarterly basis. In <br />addition, NPDES discharge monitoring reports will be submitted to the Division <br />on a quarterly basis. No deep aquifer wells are included in the hydrologic <br />monitoring plan since no additional surface disturbance is planned. <br />Information on adjacent deep aquifer monitor wells can be found in the Energy <br />Mine No. 3 permit application. <br />Six of the seven alluvial wells are located upstream of the permit boundary in <br />the Fish Creek Alluvium. These wells are located linearly across the Fish <br />Creek alluvial valley floor. Well 008-AW-3 is located adjacent to the tipple <br />area but upstream of the sediment Pond E discharge. Monitoring of the <br />alluvium will serve to identify any alluvial water quality changes prior to <br />any significant affects on Fish Creek. <br />One effluent monitoring site is included in the hydrologic monitoring plan, <br />Site 62 (or D.P. 014 as it is shown on Map 5, Fish Creek Tipple Hydrology). <br />Weekly monitoring records from this site will be reported in the applicant's <br />annual hydrologic monitoring report to the Division as well as NPDES discharge <br />monitoring which will be submitted quarterly. <br />Middle Creek flows under the haulroad in the extreme southern portion of the <br />permit boundary. Middle Creek is closely monitored as part of the Energy Mine <br />No. 3 permit. It is expected that activities associated with the Fish Creek <br />tipple will have no effect on Middle Creek. <br />The operator was found to be in compliance with the requirements of this <br />section. <br />VII. Alluvial Valley Floors - Rules 2.06.8 and 4.24 <br />Unconsolidated streamlaid deposits holding streams have been identified within <br />the proposed permit and adjacent areas and are shown on Map 5, Fish Creek <br />Tipple Hydrology. As shown on the map, three areas are acknowledged by the <br />applicant as meeting the geomorphic criteria of alluvial valley floors. These <br />areas are: 1) the flood plain of Fish Creek; 2) the flood plain of Middle <br />Creek; and 3) the flood plain of Trout Creek. The only disturbance of the <br />Middle Creek flood plain is a small area where the tipple haulroad crosses the <br />creek. Effects from the haulroad will be negligible. Furthermore, this area <br />is directly adjacent the Energy Mine No. 3 operations, which are expected to <br />have an affect on this flood plain, and will be monitored as part of the <br />Energy Mine No. 3 permit. Therefore, this area will not be considered further <br />in this document. Additional information can be found in the Energy Mine No. <br />3 permit application and findings document. <br />The Fish Creek Tipple is constructed on 25 to 35 feet of fill material. A <br />portion of the fill was placed on unconsolidated alluvial deposits of the Fish <br />Creek flood plain. The portion of the Fish Creek Tipple constructed on the <br />alluvium is isolated from the Fish Creek alluvial valley floor and associated <br />irrigation structures by bedrock outcrop and apre-existing Denver and <br />Rio Grande Railroad bed which will remain after final reclamation at the Fish <br />
