Bonneville Power Administration (BPA) proposes to install new radio towers at the Marion Substation and Sand Springs Substation communication sites in Oregon. The proposed work is required to transition the affected telecommunications systems onto new digital microwave radio frequencies or onto fiber optic infrastructure. The Marion Substation and Sand Springs Substation project involves installation of a 60 foot tall radio tower in a previously disturbed area within the substation fence line. The proposed work is required to transition the affected telecommunications systems onto new digital microwave radio frequencies or onto fiber optic infrastructure. Additionally, the radio beam path approximately 1 mile east of the Marion Substation would require tree clearing.
