3 3-84 Affected Environment, Environmental Consequences, and Mitigation fisher-gatherer resources. The project is near and crosses many water sources and appears to have unique habitats for economically useful plants, for example, the extensive basalt outcrops that are prime Lomatium habitat. Lomatium—Within the project area there exist microenvironments that support different species of plant based primarily on local hydrology, geology, and sun exposure. Lomatium habitat can be considered a microenvironment within the greater sage vegetation zone. Lomatium, referred to in English by Sahaptin native speakers as “Indian celeries,” comes in many shapes and sizes. The plant produces edible sprouts, stems, and shoots and would be harvested seasonally. Lomatium habitat in the project area constitutes portions of talus slopes and rocky lowlands along streams and creeks. For the most part, the corridor is probably too far from the pre-inundation shoreline of the Columbia River for a village or camp to be affected but hunter-fisher-gatherer groups certainly used the corridor prior to Euroamerican contact. Hunting and plant collecting parties more than likely passed through the area on their way from the Columbia River to uplands and canyons east and west of the corridor. But, this type of land use pattern would leave only a few scattered lithic artifacts across a large area and would be difficult to detect even using state-of-the-art archaeological field techniques. Environmental Consequences – Proposed Action Impacts During Construction Potential impacts to cultural resources could occur during construction of the proposed project without appropriate mitigation measures. Tower construction (see Chapter 2) would be limited to a relatively small area adjacent to existing transmission line towers. Road construction and improvements are the most likely activities to disturb unknown cultural resources. Cultural resource monitors could be provided, as necessary, to observe ground-disturbing activities associated with road improvements in areas of previously documented cultural sites. Transmission towers and access roads would be sited so as to avoid the known cultural resource sites along the corridor. Of the 14 cultural resource sites found, 12 require avoidance and two sites require avoidance. Cultural resource monitors should be present when construction excavation and/or ground disturbing activities take place in and around archaeological sites. A monitor’s presence would ensure proper handling of sensitive cultural resources if unearthed. Of the ten previously documented cultural resource sites along the corridor, nine require avoidance and one site requires avoidance plus a cultural resource monitor during construction excavation. BPA McNary-John Day Transmission Project Draft EIS February 2002
BPA McNary-John Day Transmission Project Draft EIS February 2002 Cultural Resources The project corridor transects the ancient lands of many Columbia River basin tribes. Bonneville has consulted with the Umatilla Tribes, Warm Springs Tribes, and the Yakama Nation on this project implementing the principles and protocols set forth in their 1996 Programmatic Agreement (see Appendix A, Agency Correspondence and Policies. Impacts should not occur to unknown sites with appropriate procedures to stop construction activities and determine appropriate protective measures (e.g., avoidance) if artifacts are found (please see Mitigation Measures). Impacts During Operation and Maintenance No impacts to cultural resources are anticipated during the continuing operation and maintenance of the proposed McNary-John Day Transmission Line. The towers and access roads would be sited to avoid sensitive areas, so maintenance to the towers or access roads would not affect known resources. The vegetation within the right-of-way is not dense, so it is not expected that any ground disturbing mechanical type vegetation clearing would be required. If any maintenance activities need to occur outside of the tower locations or off the access roads, a review of the sensitive areas would be required in order to avoid impacting resources. Environmental Consequences of Short-Line Routing Alternatives There are no significant cultural resources in the areas of the short-line routing alternatives; impacts are not expected for any of the alternatives. Mitigation The following mitigation measures would minimize impacts to significant cultural resources: � Locate structures, new roads, and staging areas so as to avoid known cultural resource sites. � Utilize existing access road system to the extent possible to reduce the need for new access roads. � Limit construction equipment to tower sites, access roads and conductor tensioning sites. � Limit the number of contractors to cultural resource site sensitive information on a need-to-know basis. 3-85
