President Donald Trump may be planning to permanently place Andrew Wheeler as Environmental Protection Agency Administrator.

Acting roles are typically limited to 210 days in a post, with Wheeler having now a little more than 100 days under his belt as acting head of EPA. Wheeler, who has not been nominated for the post, took the acting role in July when then-administrator Scott Pruitt resigned.
Wheeler inherited an agency in the midst of a large deregulation effort and a controversial biofuels agenda. However, Wheeler just last week said his agency can expand E15 sales to year-round without Congressional approval, a move ordered by President Trump and applauded by many agriculture groups earlier this month.
