WeADJOW MINING, LL <br />Miscellaneous Comments: <br />'04,000�0 <br />FIRST QUARTER 2012 POND INSPECTION REPORT <br />Pond Inspection Date: March 26, 2012 <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 are cleaned and/or straw bales replaced, as part of routine <br />maintenance. <br />2. Outfall 011 — This pond 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 served no further hydrologic function. The pond provided an ongoing <br />location to place ditch cleaning materials from adjacent ditches. During the quarter, the pond was <br />regraded completely to blend with the adjacent back entrance road to the mine. Outfall 011 has <br />previously been removed from CDPS Discharge Permit CO- 0000132. Future quarterly inspections will no <br />longer address this pond as it no longer exists. <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 />4. Pond B — Outfall +012 is scheduled for cleaning in summer 2012. <br />Pond D - Minor weep ( {1 gpm) from a pipe joint will need some tar maintenance. <br />Notwithstanding comments above, ponds have been maintained as designed and in accordance with the <br />approved plan. <br />Inspected By: <br />Under Direction of: <br />I. <br />James A.
