Environmental Stewardship

Environmental Stewardship


Environmental management system

Tri-State’s Environmental Management System (EMS) achieves environmental compliance, enhances strategic planning and promotes environmental stewardship.

The comprehensive EMS guides activities and ensures compliance in a systematic approach that accomplishes environmental goals and keeps facilities running efficiently. Tri-State is among the first cooperatives in the nation to adopt EMS. We continue to make sure we’re meeting or exceeding the highest standards of federal and state clean air and water standards.


Baseload facilities and their environmental controls


Our notable conservation efforts

Colorado Parks and Wildlife (CPW) honored Colowyo Mine as a Wildlife Partner of the Year in 2016 for its longstanding commitment to environmental preservation and conservation. Tri-State and Colowyo have supported and welcomed Greater Sage-grouse research projects since 2001.


The next generation of low-carbon energy technology

In a few years, the Wyoming Integrated Test Center (ITC) at the Dry Fork Power Station outside Gillette, Wyoming, will house teams competing for millions in prize money for their solutions to carbon management. Tri-State committed funds to the ITC to ensure it could move forward. The ITC is a model public-private partnership that will provide space for researchers to test Carbon Capture, Utilization and Sequestration (CCUS) technologies.
