Regulatory Process

The Bluestem Pipeline project is required to obtain a number of permits and will undergo review by local, state and federal entities.

The proposed Bluestem Pipeline project crosses a number of waterbodies and wetlands that are under the jurisdiction of the U.S. Army Corps of Engineers (USACE), including two USACE Districts (Kansas City, Kansas, and Tulsa, Oklahoma). As such, the proposed Bluestem Project will be subject to the requirements of Section 404 of the Clean Water Act, which requires that a permit be issued by the USACE prior to the start of construction.

As a federal action, the USACE permit will require that wetlands and waterbodies be surveyed and mapped along the entire project route, and will trigger the requirements of other federal and state regulations, including those regarding species with protected status on the federal and state levels (e.g., the Endangered Species Act and Migratory Bird Treaty Act) and those regarding the preservation of historic and/or culturally significant resources (i.e., the requirements of Section 106 of the National Historic Preservation Act).

Surveys are also required along portions of the proposed route for habitat that could support listed species, as well as for cultural or historic resources.
