ii. The EPP will include discussion of flood storage in Robinson <br />Lake. At a minimum, the Operating Plan will require Climax to <br />maintain available storage capacity for the state-approved Site- <br />Specific PMP event plus seepage water from the 1 Dam, 4 Dam, <br />and Robinson Dam seepage collection systems. Additional <br />storage capacity for the 100-year snowmelt will be required <br />during the times of the year when snowmelt is occurring. The <br />assumptions on which the operating criteria will be based should <br />include operating parameters that would accommodate a failure <br />of Chalk Mountain Interceptor during a PMP, and the <br />assumption that Chalk Mountain Reservoir will spill into <br />Robinson Lake. Flood routing analysis for Robinson Lake will be <br />incorporated into site-wide modeling for all Climax facilities. If <br />Climax intends to rely on removal of water by pumping from <br />Robinson Lake via the barge system or other system, this removal <br />will be modeled in conjunction with other flood modeling (as an <br />inflow to the Tenmile Creek basin) to ensure that these facilities <br />in the Tenmile Creek Basin will have adequate storage and/or <br />discharge capacity to handle the added flow. <br />iii. The Robinson Lake Operating Plan will include procedures that <br />will prevent Robinson Lake from being used for flood storage from <br />Tenmile TSF or Robinson TSF when doing so would result in <br />water levels in the lake that exceed the operational thresholds <br />required for storage of water from the Eagle River Basin plus <br />additional seepage flows identified in the operational rules. <br />Climax's currently-approved CDPS permit acknowledges the <br />possibility of bypass and upset events through the outfall on <br />Tenmile Creek. Flood flows would not be routed to Robinson Lake <br />from the Tenmile Creek basin during such events when doing so <br />would be contrary to the Robinson Lake Operating Plan. <br />iv. An annual report will be prepared that documents the flood <br />storage and release status for the year. Climax will provide a <br />copy of this report to Eagle Park Reservoir Company and the <br />Clinton Ditch & Reservoir Company concurrently with its <br />provision to the Division. <br />(c) Eagle Park Reservoir <br />i. The Revised EPP, and the SPCC and MCP documents for the <br />Site, will remove all references to the use of, or reliance on, <br />Climax Molybdenum Company <br />Climax Mine, M-1977-493 <br />Permit Amendment Application AM-06 5
