The office of Gov. Greg Gianforte announced Thursday that Chris Dorrington, a longtime state official who has led the Montana Department of Environmental Quality since 2021, will be taking the helm at the Montana Department of Transportation.
DEQ, which among other duties regulates water quality, mining and some aspects of subdivision development, will be led by current Air, Energy and Mining Division Administrator Sonja Nowakowski.
Both appointments take effect July 1, the governor’s office said. Gianforte’s prior MDT director, Mack Long, announced his retirement in March.
Dorrington previously served as the Air, Energy and Mining Division administrator under former Gov. Steve Bullock, a Democrat. When Gianforte, a Republican, named Dorrington DEQ director shortly after taking office in 2021, the appointment was lauded by both industry and environmental groups.
In Thursday’s announcement, Gianforte praised Dorrington’s tenure at DEQ, where his work has included chairing the governor’s housing task force.
“Chris Dorrington is a changemaker,” Gianforte said. “Bringing his previous experience at the agency and exceptional ability to lead, I have total confidence in him as he takes the reins at MDT. I appreciate his willingness to serve in this new capacity after his successful tenure at DEQ.”
