After serving as deputy attorney general in the 1980s, representing the Idaho Department of Health and Welfare, Fransen was the face of a number of state agencies and became the DEQ's deputy director in 2007. When Toni Hardesty retired as DEQ director in February 2012, Gov. C.L. "Butch" Otter named Fransen to the top post.
"During a time of growing federal mandates and as environmental issues are used for legal or political posturing rather than collaborative problem solving, Curt has been a stalwart and faithful executor of responsible public policy,” said Otter in a statement announcing Fransen's retirement, effective May 22.
Otter added that he was in the process of determining Fransen's successor.
