Consequences, and Mitigation
are in development planning stage, with construction expected in 2002-2003. Generally,
once the sites are developed, they are transferred to Bureau of Indian Affairs and public
use is no longer permitted. In a few cases, the tribes have agreed to share use and the
Corps retains management provisions.
Utility Line Crossings
The project corridor crosses approximately 61 utility lines (e.g., gas lines, electric, fiber
optic, telephone, irrigation, and water lines). The proposed transmission line would be
located in the corridor with a number of existing Bonneville transmission lines: McNary-
Horse Heaven No. 1 line and McNary-Ross No. 1 line from corridor mile 0 to 18; Horse
Heaven-Harvalum No. 1 line and McNary-Ross No. 1 line from corridor mile 18 to 76;
Ashe-Marion No. 2 line and Ashe-Slatt No. 1 line join with the proposed transmission
line right-of-way from corridor mile 23 to 27; and Hanford-John Day No. 1 line joins
with the project corridor at corridor mile 68 to the John Day Substation.
A Cascade Natural Gas 4- pipeline intersects the project corridor in the vicinity of
structure 6/1. A PNW 20-inch gas pipeline crosses between structures 6/3 and 6/4. An
El Paso Natural Gas Company 12-inch gas pipeline and 10-inch gas pipeline cross
between structures 8/1 and 8/2. A PNW 26-inch gas pipeline crosses near structure 15/3.
Recreation
Formal recreational opportunities in the project vicinity are listed by county in Table 3-2.
Informal recreational opportunities in the vicinity of the project corridor include upland
bird hunting, with proper authorization, along certain areas of the corridor on the south
side of SR 14 in Benton County and various water sports on the Columbia River along
the entire length of the project corridor. SR 14 is designated as a Scenic and Recreation
Highway by the state of Washington.
