Corps officials worked with state and Federal agencies and Native American Nations to minimize harm to the aquatic ecosystem. They prepared a Biological Evaluation in accordance with the Endangered Species Act and Environmental Assessment in accordance with the National Environmental Policy Act. The officials assure full compliance with the acts prior to starting.
Potential dredging and disposal operations impacts are also avoided through implementation of U.S. Fish and Wildlife Service-designated timing restrictions.
In addition to the environmental concerns, Corps proposed dredging is confined to removal of recently deposited sediments within the previously dredged channel. By limiting the dredging width and depth, any possible submerged cultural resources are not affected.
