Duckworth's office said she has holds on the nominations of Bill Wehrum to lead the EPA’s Office of Air and Radiation and Michael Dourson to head the Office of Chemical Safety and Pollution Prevention.
In a statement, Duckworth cited the pair’s history working on behalf of industries they would regulate if the Senate confirms them to their positions at the EPA.
She said Dourson’s career as a chemical industry representative compromises his ability to oversee the industry. And she called out Wehrum for his “record of opposing the Renewable Fuel Standard,” the federal mandate on biofuel blending requirements.
“In the ten months that Donald Trump has been president, his administration has launched unprecedented attacks on the Renewable Fuel Standard — attacks that fly in the face of promises Trump made as a candidate to our nation’s farmers that he would champion the [Renewable Fuel Standard] program if elected,” Duckworth said in a statement.
“Any senator who supports the [Renewable Fuel Standard] program, our farmers, and our commitment to the environment and energy dependence must oppose his nomination.”
Wehrum and Dourson are among the more controversial nominees put forward by President Trump. The Environment and Public Works Committee, on which Duckworth sits, was due to consider the nominees on Wednesday but committee Republicans canceled the vote Tuesday night.

"We’ll let each senator speak for themselves," he told reporters. "We want to move all of the nominees together, so there were concerns and we decided to move it to next week."
Wehrum’s nomination has become a proxy battle over the Renewable Fuel Standard, with some senators, including Republican Sen. Chuck GrassleyChuck GrassleyFormer Sen.

Her support for Wehrum is critical to moving the nominee because Republicans hold only a one vote margin in the EPW committee.
She said Wednesday that discussions over the RFS and the nomination are ongoing.
“Holding the EPA’s feet to the fire has put us on a path to receive strong reassurances on biofuel volumes and the EPA’s commitment to follow both the letter and the spirit of the RFS, as well as a commitment to not pursue other policies harmful to our farmers across Iowa,” Ernst said in a statement.
“My staff and I will continue to keep a watchful eye as these assurances come to life, and while we are still in negotiations, I do feel good about the direction we are headed.”
Iowa Gov. Kim Reynolds (R) spoke Wednesday with both Pruitt and Trump, and said the Trump call was "very productive."
"Both of them personally affirmed to me their continued commitment to the Renewable Fuel Standard,” she told reporters.
