Kerr inspects all <br />sedimentation ponds on a quarterly basis. Inspections include <br />evaluation of accumulated sediment levels relative to design <br />~ sediment storage capacity to verify that design stormwater storage <br />capacity is maintained at all times. If inspections indicate that <br />. sediment accumulations are"at or near the design sediment level, <br />Kerr removes accumulated sediment from the pond(s) within a <br />reasonable period (typically 30 to 60 days) following the <br />inspection. Both pond inspection reports and documentation of pond <br />clean-out are retained at the minesite and are available for <br />inspection by authorized agency representatives. Based on direct <br />observation of pond storage levels at the time discharge occurred, <br />the discharge resulted from: <br />Rainfall or snowmelt runoff volumes less than or equal <br />to the design 10 year, 24 hour storage volume <br />[] Rainfall or snowrt:elt runoff volumes greater than the <br />design 10 year, 24 hour storage volume <br />
