No dredging takes place at this facility, there are no temporary
siltation structures involved in this operation and no mining will
be done in a river or waters of the United States . A U. S . Army Corps
of Engineers 404 Permit is not required for this operation because
there are no jurisdictional wetlands on the site . The operator has

recirculated to be used again in the processing plant . There will
be no earthen dams on the mined area.
