Table 2-3: Summary of Impacts and Mitigation Measures for the Proposed Action and No Action Alternative, p 4
Proposed Action No Action
Potential Impact Mitigation Measures Potential Impacts
Water Resources and Wetlands
Cultural Resources
� Disturbance of undiscovered hunterfisher-gatherer
resources or unrecorded
cultural resources
� Avoiding refueling and/or mixing hazardous materials where accidental
spills could enter surface or groundwater
� Avoid mechanized land clearing within wetlands and riparian areas to
avoid soil compaction from heavy machinery, destruction of live plants,
and potential alteration of surface water patterns to reduce groundwater
turbidity risk
� Anticipate and avoid, as required, contaminated soil and underground
tanks during construction activities near pipelines and agricultural and
other historic projects; anticipate and avoid orphaned wells, as required,
particularly near the Washington communities of Plymouth, Paterson,
Roosevelt, Sundale, and Towal
� Avoiding refueling and/or mixing hazardous materials where accidental
spills could enter surface or groundwater
� Implement the Spill Prevention and Contingency Plan
� If archaeological or historic materials are discovered during construction,
surface-disturbing activities at the site would cease, and Bonneville, State
Historic Preservation Office, and tribal personnel would be notified to
ensure proper handling of the discovery
� Locate structures, new roads, and staging areas so as to avoid known
cultural resource sites and limit contractor access to cultural resource site
sensitive information on a need-to-know basis
� The Umatilla Tribes CRPP identified ten TCP areas and recommends the
presence of a tribal monitor during all ground disturbing activities; tribal
consultation throughout the construction process (from the planning phase
through the completion of the project); and collaboration between Jones &
Stokes, Bonneville, and the CRC and the Board of Trustees to set up
required consultation protocols on site mitigation and management
� The Umatilla Tribes would like Bonneville to ensure that the cultural and
natural resources are protected as well as guaranteed traditional use of this
area, in accordance with treaty reserved rights
� No impact
