Draft Supplement to the Environmental Statement Fiscal Year 1975 Proposed Program. Facility Location Evaluation for Richland Area Electrical Service

摘要

The proposal involves the construction of 35.2 miles of 230-kV and 3.6 miles of 115-kV transmission line as well as the associated construction of three new substation facilities. A total of 697 acres of the new easement required for the proposed transmission facilities would occur entirely within the Atomic Energy Commission's Hanford Reservation where land uses and public access are already restricted for safety reasons. The removal of vegetative cover in the reservation during construction operations will increase an already high potential for wind erosion. An additional 5 miles of new right-of-way easement will be required outside of the Hanford Reservation crossing primarily sagebrush rangeland with some irrigated cropland being removed from production. Depending upon actual sites selected for the three new substation facilities a total of up to approximately 60 acres of sagebrush rangeland would be permanently removed from production. Disturbance of game in the immediate vicinity of the transmission facilities will occur during construction, as will some soil erosion primarily during and immediately after construction, siltation in nearby streams, disturbance of nearby residents from noise and dust during construction and some degration of AM reception immediately adjacent to the right-of-way. 15 figs.
