At this time, no remedial sediment clean-out work is scheduled for <br />the next five-year permit term. <br />Sedimentation Pond 003. Design information and calculations for this pond were submitted <br />in the Seneca II Permit Renewal Application (8/27/86), and subsequently approved by CMLRD. <br />In 1986 and 1987, Sedimentation Pond 003 was resurveyed as part of Seneca's annual <br />sediment survey. The survey information was utilized to develop. a contour map. This data <br />was used to calculate the remaining sediment storage beneath the principal spillway. <br />Following is a comparison of the design, the 1986 and the 1967 annual survey volume <br />calculations: <br />• <br />7-11A-6 <br />
