F. Sedimentation Ponds 008 through 018 Design Parameters
In accordance with Rule 4.05.2, Ponds 007 through 018 will be used to prevent, additional
contributions of sediment to stream flow or runoff outside the permit area due to mining
disturbance. Pond 011 has been fully reclaimed and some of the drainage area that was
previously to be handled by these ponds is now handled by Pond 013. The pond designs and or
run-off calculations for the sedimentation ponds are shown below:

Ponds 007 and 008 are the only ponds that will remain after reclamation. Pond 013 will remain
for some time after the reclamation of the surrounding land but will not be permanent. The
demonstration to allow retention of Pond 007 is Attachment 2.05.3(3)-16. The demonstration to
allow retention of Pond 008 is Attachment 2.05.3(3)-19. Map 2.05.3(3)-1 shows the locations of
all ponds. Pond 014 was the post -mine conversion of the pre -mine SAE #2. It was reclaimed
