Vantage to Pomona Heights Chapter 3 230 kV Transmission Line Project FEIS Affected Environment PAGE 3-178 Level 3 or Level 5 roads provide access to the Selah Butte area and the Columbia River BLM parcels. Within the Saddle Mountains MA, the BLM has designated lands as either “Open” for off-road use or “Limited” road restricted use. The southeast side of the Saddle Mountains MA is designated as “Limited” access for off-highway vehicle (OHV) use and most of the northwest side of the Saddle Mountains MA is designated as “Open” access for OHV use (see Appendix A- Jurisdiction, Recreation and Special Management Areas Map). In total, approximately 4,300 acres are designated as “Open” and 18,700 acres are designated as “Limited” within the Saddle Mountains MA. Reclamation also regulates roads for public or private use on Reclamation land. Reclamation’s focus in the Project study area is water-related projects such as dams, reservoirs, and irrigation. Roads are primarily used for accessing those facilities. Reclamation does not have maintenance levels or classifications for their road system, roads are either paved or gravel and maintained on an as-needed basis. Reclamation roads are limited to the vicinity of Vantage Substation. Roads servicing JBLM YTC are maintained by the U.S. Department of the Army (Army). Within recent years, JBLM YTC has completed improvements in road network and structure, road closures and realignments, and channel crossings. Nearly 300 miles of existing roads have been resurfaced with crushed rock. Approximately 14 miles of roads were re-routed away from stream channels and areas with a high potential for erosion. Approximately 14 miles of deteriorated or poorly located roads were closed to vehicle traffic and rehabilitated. In addition, 390 stream channel crossings have been improved with culverts and fords. The JBLM YTC has perimeter roads for access which also serve as a fire break (Army 2010). 3.7.2.4 Navigable Waterways The U.S. Army Corps of Engineers (USACE) has jurisdiction authorizing certain structures or working in or affecting navigable waters of the United States pursuant to Section 10 of the Rivers and Harbors Act of 11899. Navigable waters of the United States are defined in the Code of Federal Regulations (33 Code of Federal Regulations [CFR] Part 329.4). Navigable waterways within the Project study area consist of the Columbia River. The Columbia River is a designated navigable waterway for its entire length in the United States. The River has been and continues to be a major source of transportation, electricity, irrigation, and fishing. The Wanapum Dam and Priest Rapids Dam have essentially created two lakes along the River in the Project study area: the Wanapum Lake and Priest Rapids Lake. According to 33 CFR Part 322 “Permits for Structures or Work in or Affecting Navigable Waters of the United States,” Section 322.5(i)(1) (Special Policies/Power Transmission Lines), a Section 10 permit would be required for power transmission lines crossing navigable waters of the United States. The proposed Project requires a Section 10 permit. The USACE also authorizes the acceptable clearances for conductors crossing navigable waters. 3.7.3 Current Management Considerations 3.7.3.1 Federal and State Highway Management FHWA FHWA review and concurrence is required by WSDOT for approving Pacific Power’s application to cross I-82 land owned by WSDOT. The FHWA works with WSDOT to permit third parties to use interstate property for non-highway uses that do not impact safety and operations on the interstate and the proposed use shall not expose the facility’s users to other hazards.
