Environmental responsibility

Protecting natural resources through responsible development

In all aspects of project design, construction and operation, DATC is committed to responsible development and minimizing Zephyr Power Transmission Project’s impact on the landscape, ecosystems, wildlife and communities.

To this end, wherever practicable, our environmental and engineering teams strive to ensure the proposed route maximizes use of existing designated corridors and avoids densely populated areas, private land, critical wildlife habitats, tribal lands, military bases and other socially, environmentally or culturally sensitive areas.

Our responsible approach to Zephyr’s development:

We are working closely with state, federal and local permitting agencies to make sure the siting and permitting process is transparent, timely and efficient. We place a priority on ensuring that all stakeholders have an opportunity to voice their opinions about the project.

  • In all aspects of route development, we do our best to site on state and federal land (currently more than 60 percent of proposed route) and to avoid sensitive areas across the entire corridor.
  • If that’s simply not practicable, we apply design techniques to minimize impacts.
  • In instances where impacts are unfortunately unavoidable we will work with local, state, and federal agencies, as well as other key stakeholders, to appropriately mitigate potential effects.

Responsible development

Zephyr Power Transmission Project’s primary wind developer, Pathfinder Renewable Wind Energy, LLC, is a leader in responsible wind energy development. This wind generation project is located on 150,000 acres of ranch land in eastern Wyoming. The site was chosen through a collaborative process that led to identification of the most environmentally benign – yet windy – sites in the region.

Zephyr represents an environmentally superior project that not only will benefit the people of the states through which it passes, but also will serve to advance the nation’s goal of building the infrastructure needed to support a clean energy economy while furthering our energy security and independence.

Responsible conservation

In central Wyoming, Pathfinder created the Sweetwater Conservancy – a refuge totaling 700,000 acres – to demonstrate its commitment to the environment by protecting open spaces and improving wildlife habitat. Because of the Sweetwater Conservancy, Wyoming ranch land and wildlife habitats are now protected from future development.
