LLC <br />{3 <br />l„ <br />,. <br />THIRD QUARTER 2007 POND INSPECTION REPORT <br />Pond Inspection Date: September 28, 2007 <br />Miscellaneous Comments: <br />1. 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 were cleaned, etc. Some straw bales replaced. <br />2. Outfall O l 1 - Outfall 011 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 Ol 1 has been removed <br />from CDPS Dischazge Permit CO-0000132. <br />3. Outfall 009 - (A Pond) had approximately 30 cy of sediment removed during the quarter. <br />4. Outfall 012 - (B Pond) had approximately 500 cy of sediment removed and temporarily stored in the <br />Outfall O10 -East Yard pond. Subsequently, 200 cy was removed from 010 and hauled to the II West <br />Refuse stockpile for final disposal. <br />5. Outfall 016 - (D Pond) had approximately 800 cy of sediment removed and hauled to the WVF coal <br />refuse area. <br />6. 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 vazious 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.
