Program participants are the <br />Geological Survey, Service, Bureau of Indian Affairs, and Reclamation. These projects are <br />necessary to ensure that federally constructed irrigation projects are in compliance with the <br />Endangered Species Act and Migratory Bird Treaty Acl. The program is managed by <br />Reclamation on behalf of the participating agencies. <br /> <br />An interdisciplinary (10) team was formed in October 1998 with the assignment to develop a <br />selenium remediation plan for the OMW A. The team members were: <br /> <br />Speciaiity <br /> <br />Steve McCall - Reclamation <br />Del Smith - Reclamalion <br />Larry Bums - Reclamation <br />Jone Wright - Reclamation <br />Dave Buder - Geological Survey <br />Barb Osmundson - Fish & Wildlife Service <br />Mike Baker - Reclamalion <br /> <br />Environmental analysis <br />Wetlands/ ground water <br />Design & cost estimates <br />Public information <br />Water & sediment monitoring <br />Biota impacts & monitoring <br />Team leader/ general planning <br /> <br />Publie SeoDin!! <br /> <br />In November 1998, Ihe ill Team held a tour and workshop to inform the public and interested <br />agencies about the problems and issues at the OMWA and to obtain the public's ideas on how to <br />correct the problems. Two newsletters were developed and distributed to stakeholders to present <br />information on the alternatives and study progress. and solicil stakeholder inpul. Nineteen <br />remediation options, suggested by the public and slUdy team, were then screened (see Table I in <br />the appendix). <br /> <br />From the scoping process eight options met the initial screening criteria and were developed by <br />the ID Team: <br /> <br />I. Treatmenl Plant <br />2. Evaporation Ponds <br />3. Collect and Convey Directly to Ihe Colorado River <br />4. Divert and Reuse <br />5. Deep Well Injection <br />6. Dilute or Rush <br />7. Retire Agricultural Lands <br />8. Remove Beaver Dams <br />
