r'" r Water QUalitv standards, toxic effluents. and threatened and endanGered soecies comoliance (230.10(b)) A project which would result in exceedances of State water quality standards or criteria set under CWA section 307 regarding priority pollutants would not be in compliance with the Guidelines. In the case of the Animas-LaPlata Project which potentially affects the water quality under the jurisdiction of several entities (The Southern Ute Tribe, the Ute Mountain Ute Tribe, Colorado, and New Mexico), the SDEIS analyses will need to document the project water quality impacts based on the standards of all entities. Reclamation should seek the assistance of the State and Tribal water quality standard setting agencies and document that project operations (pumping from the Animas and LaPlata, irrigation return flows to the LaPlata and Mancos, stream accretions to the LaPlata, etc.) comply with water quality standards of the various stream reaches. Demonstration of compliance with the Endangered Species Act is also a requirement of the Guidelines. It appears that the entire Animas-LaPlata Project would have received a jeopardy opinion concerning the Colorado River squawfish (Draf~ Biological Opinion, U.S. Fish and Wildlife Service. May 7, 1990). While the reasonable and pFooento--a-l.ternat.i vesubsequently developed pursuant to Section 7(d) of the Endangered Species Act would offset jeopardy to the Colorado squawfish, that alternative is limited to Project facilities (Phase I) which result in a net annual depletion of less than 57,100 acre-feet (Final Biological Opinion, U.S. Fish and Wildlife Service, October 25, 1991). Upon completion of Phase II, full development and operations would result in a net annual depletion on 154,800 acre-feet of water. Further, according to the Final Biological Opinion, approximately 7 years of research effort is to be completed before further consultation for the entire project will occur. SiGnificant DeGradation (230.10(c)) The analysis necessary to make a determination concerning significant degradation includes information on project construction and operational adverse impacts on: human health and welfare issues (to include but not limited to municipal water supplies, fish, wildlife and special aquatic sites); aquatic life and other wildlife dependant on aquatic ecosystems (in particular the potential for transfer or 'spread of pollutants through biological, physical or chemical processes); aquatic ecosystem diversity, productivity and stability (such as loss of habitat, etc.); and recreational, aesthetic and economic values. The analyses need to present the factual determinations, scope and intensity of the 'project related adverse effects on these resources. The analyses need to consider the significance of adverse impacts from both an individual and cumulative viewpoint. 2
