Compliance Inspection for Wyoming Transmission Line

The Situation

The construction of a new 1,000-mile electric transmission line stretched across Wyoming and Idaho where Eocene assisted as the compliance inspection contractor, along with providing the plan of development and coordinating tribal consultation. The project crossed portions of BLM-managed lands and contained eligible cultural sites, habitat for a number of protected plant and animal species, and sensitive regions, including biological, cultural, paleontological, and geological throughout the project area. 

The client needed a third party contractor to conduct the compliance inspection for the project, along with heavy coordination that included a project team of approximately 10 individuals.

  • Inspection and monitoring on behalf of the BLM.
