Upon the receipt of any application with accompanying plans, it shall be the duty of the director to examine same and to furnish copies of the application and plans to, and consult with, other state agencies having an interest in the stream channel to determine the likely effect of the proposed stream channel alteration upon the fish and wildlife habitat, aquatic life, recreation, aesthetic beauty, and water quality values of the stream. The director shall furnish a copy of each application and all accompanying materials to the department of lands. Within twenty (20) days of the receipt of copies of such application and plans from the director, such other state agencies shall notify the director whether the proposed stream channel alteration will have an unreasonably detrimental effect upon these stream values and shall include with such notification recommendations of alternate plans, if any, determined by such agency to be reasonable to accomplish the purpose of the proposed stream channel alteration without adversely affecting such stream values.
