i <br />JXBOW alffllyG LL <br />SECOND QUARTER 2010 POND INSPECTION REPORT <br />Pond Inspection Date: June 21, 2010 <br />Miscellaneous Comments: <br />I . The SWMP control devices were inspected and all SWMP control devices were found to be in fair <br />condition. Performed further routine SWMP maintenance during the quarter on Elk Creek mine and <br />facility roads. Sumps in front of straw bales will be cleaned, straw bales replaced, as part of spring <br />maintenance. <br />2. Outfall 011 - Outfall O l 1 formerly served as a mine water pond for the Sanborn Creek Mine. The <br />pond does not collect surface drainage. With closure of the Sanborn Creek Mine, the incised pond <br />associated with Outfall 011 serves no further hydrologic function. The pond currently provides an <br />ongoing location to place ditch cleaning materials from adjacent ditches. Outfall 011 has been removed <br />from CDPS Discharge Permit CO-0000132. <br />3. Sediment and Water Level Determination - When sediment enters a pond, it is deposited unevenly, <br />usually collecting at the inlets rather than evenly across the bottom of the pond. Reported sediment levels <br />are based upon the inspector's observations made throughout the quarter during routine inspections in <br />combination with knowledge of the pond structure. The reported pond water level is also determined by <br />observations relative to the various landmarks in the pond (depth to bottom, primary riser, etc.) <br />Notwithstanding comments above, ponds have been maintained as designed and in accordance with the <br />approved plan. <br />Inspected By: ' <br />James A.
