A resource and impact study regarding a proposed power line between Twin Falls, Idaho, and Las Vegas has been completed and will be aired at a public planning meeting Thursday, Feb. 14, at 7 p.m. in the Delta City Hall.

A branch from the 500-kilovolt transmission line is planned between Ely, Nev., and the Intermountain Power Plant near Delta. The public has been invited to comment at the Delta meeting about proposed alternative routes that will be included in the final Environmental Impact Statement.The Idaho Power Co. wants to expand power grids in the Western states and the 400-mile long line would accomplish that purpose.

The project is expected to be completed in 1993 and construction will employ about 120 workers.

Information about biological, earth, culture, visual resources and land use impacts has been gathered for the impact statements. Data has been obtained through the cooperation of federal, state and local agencies and through the use of satellite imagery and digital terrain mapping.

Potential impacts could involve threatened and endangered species, including the desert tortoise; sage grouse and longhorn antelope habitat; wetland and riparian areas; grazing and agricultural land; military operating areas, such historical and cultural sites as Minidoka Relocation Center and Bristol Well; recreation areas like Hagerman Fossil Beds National Monument and Great Basin National Park; and views from residences, scenic highways and other points.
