The Greater than Class C (GTCC) Environmental Impact Statement (EIS) evaluated the potential impacts from the construction and operation of a new facility or facilities, or use of an existing facility, employing various disposal methods (geologic repository, intermediate depth borehole, enhanced near surface trench, and above grade vault) at six federal sites and generic commercial locations. For three of the locations being considered as possible locations, consulting tribes were brought in to comment on their perceptions on how GTCC low level radioactive waste would affect Native American resources (land, water, air, plants, animals, archaeology, etc.) short and long term. The consulting tribes produced essays that were incorporated into the EIS and these essays are in turn included in this collection. This essay was produced by the Confederated Tribes of the Umatilla Indian Reservation.

This study provides an analysis of watershed response to climate change and forest fire impacts, to better understand the hydrologic budget and inform water management decisions for present and future needs. The study site is 2,365 km2, located in the upper Umatilla River Basin (URB) in northeastern Oregon. The Precipitation Runoff Modeling System, a distributed-parameter, physical-process watershed model, was used in this study. Model calibration yielded a Nash Sutcliffe Model Efficiency of 0.73 for both calibration (1995-2010) and validation (2010-2014) of daily streamflow. Ten Global Climate Models using Coupled Model Intercomparison Project Phase 5 experiments with Representative Concentration Pathways 4.5 and 8.5 (RCP), were used to observe hydrologic regime shifts in the 2020s, 2050s, and 2080s. Mean center timing of flow occurs earlier in the year in both pre- and post-fire conditions, where there are increased winter flows and decreased summer flows throughout the 21st century. Change in temperature and percent change in precipitation is more variable in the summer than winter increasing over time, with a slight decrease in winter precipitation in the 2080s in RCP 8.5. Temperature increases 1.6°C in RCP 4.5 and 3.3°C in RCP 8.5 by the end of the 21st century. The ratio of Snow Water Equivalent to Precipitation decreases 96% in the 2080s in RCP 8.5 before forest cover reduction, and decreases 90-99% after forest cover reduction. Potential basin recharge and the base-flow index are both sustained throughout the 21st century with slight declines before forest cover reduction, with an increase in basin recharge and increase in base-flows in the 2080s after fire-burns. However, the simulated sustained base-flows and area-weighted basin recharge in this study, do not take into account the complex geologic structure of the Columbia River Basalt Group (CRBG). A more robust characterization and simulation of URB aquifer recharge would involve coupling the PRMS model with a groundwater model in a future study. Although groundwater recharge in the CRBG in the URB is not well understood, the long-term decline of groundwater storage presents a serious environmental challenge for the Confederated Tribes of the Umatilla Indian Reservation and communities in the URB.

The purpose of this case study was to compare the news coverage of The Umatilla chemical weapons by examining newspapers from different communities: The Oregonian and The Hermiston Herald. The author examines solution frames, pluralistic frames, episodic frames, and thematic frames and compares them across two newspapers. The study found the difference was not significant when comparing the use of solution frames between The Hermiston Herald and The Oregonian. In addition, there was not a significant difference in use of pluralistic framing by The Hermiston Herald and The Oregonian. However, there was a significant difference in the sources presented in the newspaper articles. There was also a significant presence of episodic frames compared to thematic frames in both the newspapers under examination.

This presentation is a project overview and discussion of Native American participation in preparing documents for the Greater Than Class C Environmental Impact Statement. Tribal representatives were involved in the assessments at the Hanford Site, Nevada Test Site, and Los Alamos National Lab.

671 pages / It is evident from a study of the history of these Indians, that the Warm Springs, together with other Oregon tribes, did not benefit greatly from the Government system of colonizing and reservations. It is true that they received the advantages of education and medical service furnished by the Government in accordance with treaty stipulations, and some protection from their enemies; but the value of these advantages may be questioned.
