In April of 2003, the U.S. Department of Energy awarded a $256,476 grant to the Tulalip Tribes of Washington State to ''assess the feasibility of developing biogas generation facilities to convert manure and other biomass resources into electricity to help meet the Tribe's energy needs from a renewable energy source.'' During the past year and a half, the Tulalip Tribes, working cooperatively with area dairy producers, have completed a comprehensive assessment of the feasibility of developing a biogas generation facility in Snohomish County. This work included an assessment of significant dairy and non-dairy biomass resources in Snohomish County, an analysis of preliminary design elements for a biogas facility, and a baseline analysis of engineering and cost values of constructing one such facility at the Monroe Honor Farm, a dairy farm formerly operated by the Washington State Department of Corrections. This comprehensive feasibility study, including work by some of the world's foremost experts in the fields of biomass production, has concluded that development of a biogas facility in Snohomish County is both technologically and economically feasible. The final report outlined here summarizes the work performed under the DOE grant, and provides full documentation of the study results. The final report consists of two parts: Part I--Project Summary, is a full color 12-page booklet entitled: ''The Snohomish Basin Biogas Project Feasibility Study Executive Summary'' (December 1, 2004). This booklet is provided herein as Attachments 1-6. Each attachment is in Adobe Acrobat (.pdf) file format. The files range from 18.2 MB to 34.8 MB each. The cumulative file size is 137.6 MB. The Project Summary booklet contains the following required elements of the DOE final report: Project Overview; Objectives; Description of Activities Performed; Conclusions and Recommendations; and Lessons Learned. Part II-Comprehensive Business Plan, is a compilation of task deliverables (provided as attachments) that comprise the work supported by DOE during the course of this study. The cooperative agreement between the Tulalip Tribes of Washington State and the U.S. Department of Energy stipulated that the biogas feasibility study should include the following tasks: Site-specific renewable resource assessment; Review of tribal load assessment and export markets; Consideration of transmission and interconnection needs; Technology analysis; Economic analysis; Consideration of environmental benefits and impacts; Consideration of cultural, social, and community benefits and impacts; Preliminary system design; Consideration of training and other professional development needs; Consideration of long-term operation and maintenance needs; and Business planning needed to move from feasibility into project implementation.
