XBOW MINING LLC <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 are cleaned and/or straw bales replaced, as part of routine <br />maintenance. <br />2. Outfall 011 - 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 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 />4. Pond 009 — A Pond — Approximately 120 CY of material removed, hauled to GOB on 8/26/2011. <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 />James A.
