Document Description
This agreement pertains to the Royal Mountain King Mine (RMK) NPDES Discharge System Project, which involves the construction of a discharge system that will provide for the capture and collection of spring water into Skyrocket Pit (SRP) and discharge of water from SRP into Littlejohns Creek Diversion Channel. The discharge from SRP will be controlled by automatic valves held in six concrete vaults near the base of the SRP dam. Water will pass through 1,500 feet of 32-inch HDPE. Width of disturbance for pipeline construction is 25 feet. The discharge structure is a concrete flume measuring approximately 110 feet long, 10 feet wide and 6 to 10 feet in height. Riprap aprons approximately 50 feet wide by 60 feet long will be placed at entrance and exit of the flume, to prevent scour and eroding of the creek. A concrete headwall 80 feet in width will divert streamflow into the flume, as described in Notification 1600-2007-0180-R2.
