Figure 22 <br />Hydrology Map <br />(1) Sedimentation Pond Location <br />The location of sedimentation ponds, whether temporary <br />or pennanent, should be shown on the Hydrology Map. <br />(2) Sedimentation Pond Identification <br />Each sedimentation pond should be labeled with a unique <br />identification number. Construction specifications should <br />be developed for each individual sedimentation pond. A <br />unique identification number wi11 aide in cross referencing <br />between the Hydrology Map and the specifications found in <br />the text or in the Exhibits for hydrology. <br />(3) Surface Water Monitoring Station <br />The discharge from each sedimentation pond should be <br />monitored in accordance to the frequency and analytical <br />requirements of the Division and the Colorado Department <br />of Health, Water Quality Control Division. For baseline <br />surface hydrologic data, surface water monitoring stations <br />should be located along drainages and/or streams. These <br />monitoring stations will remain througout the life of the <br />mine to monitor surface hydrological conditions and changes. <br />(4) Existing Domestic Well <br />The operator should locate existing domestic wells within <br />the permit area and adjacent areas. The Colorado State <br />Engineer's Office can aid the operator in the location of <br />adjudicated water wells. The operator should receive <br />permission from the owner of the domestic well so that <br />ground water hydrologic data can be measured. <br />(5) Ground Water Monitoring Well <br />All ground water monitoring wells used..by the operator <br />should be identified on the Hydrology Map. These wells <br />will be used to develop a baseline description of the <br />ground water hydrology for the proposed permit and adjacent <br />areas, and they can also be used for monitoring ground <br />water conditions and changes throughout the life of the <br />project. <br />(6) AVF Monitoring Well <br />Any AVF (Alluvial Valley Floor) monitoring wells should <br />be indicated on the Hydrology Map. Because of the impor- <br />tance and the complexities involved with identification and <br />monitoring. of alluvial valley floors, the operator should <br />
