OKLAHOMA CITY (AP) — Gov. Mary Fallin's Secretary of Environment Gary Sherrer is resigning.
Sherrer says in a letter to Fallin dated Friday that he plans to resign by Monday, the start of the new fiscal year.
Fallin says she plans to consolidate the secretary of environment and energy positions into one cabinet post and Sherrer said he didn't feel like he had the knowledge and expertise to handle both positions.
Fallin described Sherrer as a "strong voice for sensible, commonsense policies."
Sherrer is a former Democratic state legislator who Fallin credited for working with policymakers on both sides of the aisle.
Deputy Secretary of Environment Tyler Powell is expected to fill in for Sherrer on an interim basis.
The energy secretary position was left vacant after Michael Ming resigned in May.
