Diamond Pipeline believes that developing and maintaining constructive relationships with tribal communities is not only good business but the right thing to do. Our goal is to communicate with tribal governments in an open and transparent manner that respects the sovereignty and culture of each tribe, while sharing information about our activities in the area. We are committed to collaborative partnerships with federal, state and local agencies and tribal governments and will continue to engage with each group in an open and respectful manner.

Since the early days of the project we have been committed to consulting with tribal governments and we have worked diligently whenever possible to incorporate their input into the design and construction of the pipeline. Where concerns were raised about the route, we carefully considered the concerns and possibilities to reroute the pipeline, to use less invasive installation technologies, or to provide access to the right of way during construction activities for trained cultural monitors, some of whom are provided by the requesting tribes. We also completed the Section 106 intergovernmental consultation process established by the U.S. Army Corps of Engineers.

Cultural Resource Protection during Construction

Following the Section 106 consultation, we entered into voluntary agreements with multiple tribes to employ additional tribal monitors at specific culturally sensitive locations. This action is above and beyond what was required by the U.S. Army Corps of Engineers (USACE). We are very appreciative for the tribes sharing their knowledge and expertise to help us avoid or minimize impacts to cultural resources.

Tribal monitors, working alongside archaeologists, assist in the identification and protection of cultural resources that non-tribal specialists may not recognize. Such resources may include tribal sacred sites, traditional plant collection areas, and other traditional-use areas. If a tribal monitor or an archaeologist determined a site is of potential cultural significance, work stopped and the Diamond Pipeline project team followed the guidelines developed in the project’s Cultural Resources Monitoring and Discovery Plan as well as applicable federal and state rules concerning cultural finds. Work could not continue at that location until consultation was completed with the USACE or the State Historic Preservation Office.
