THIRD QUARTER 2017 POND INSPECTION REPORT <br />Pond Inspection Date: September 28, 2017 <br />Miscellaneous Comments: <br />1. The SWMP control devices were inspected and all SWMP control devices were found to be in fair <br />condition. Routine quarterly maintenance to sumps was conducted. <br />2. 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 />Under Direction of: / <br />-7- -1 <br />1: <br />A.
