The Columbia Biogas anaerobic digestion facility enjoys strong community support.

A landmark Good Neighbor Agreement between Columbia Biogas and the Cully Association of Neighbors was finalized in July 2011. A Neighborhood Advisory Committee has been created and the Agreement addresses communications and complaint procedures, operations, and environmental and livability standards that support long-term facility operations and sustainability.

Key provisions of the Agreement that support Columbia Biogas’ commitment to the neighbors and local businesses include the following:

  • Encouraging residents of the neighborhood and others near the facility to apply for employment opportunities at the facility. A Jobs Subcommittee was formed and is establishing a job training, recruiting and hiring program.

  • Considering proposals for uses of organic-based fertilizer products that benefit the community.

  • Making the facility available for tours by educational institutions, including local schools, colleges and after-school programs.

  • Cooperating with the Cully Association of Neighbors and Metro to establish a community enhancement fund created to benefit community enhancement programs in Cully and other specified stakeholders affected by the facility.

“This document was truly a collaborative effort,” said Kathy Fuerstenau, Chairwoman of the Cully Association of Neighbors. “I appreciate Columbia Biogas’ cooperation on developing a Good Neighbor Agreement that could possibly stand as an agreement model for other facilities that are bound to come. When building any successful relationship, whether it is personal or business, you require a strong foundation and good communication. I think that all the community members that worked on developing the agreement can agree that we have come a long way and look forward to continue to build on what we have started. I hope and trust that the Columbia Biogas facility will become an asset to our area and region.”

Other stakeholders participating in the development of the Agreement include the following:

  • Concordia Neighborhood Association (CNA)

  • Verde

  • Hacienda Community Development Corporation (Hacienda CDC)

  • Native American Youth and Family Center (NAYA)

  • Columbia Slough Watershed Council (CSWC)

  • Central Northeast Neighbors (CNN)
