Jewell steps into the position as Interior prepares to roll out rules governing "fracking" on public lands, flesh out plans for federal wind projects and handle the impact of sequestration cuts on national parks.
Jewell replaces Ken Salazar, who had served as interior secretary since the beginning of President Obama’s first term.
Salazar congratulated Jewell Friday on Twitter, and expressed gratitude for his tenure with Interior.
“I'm humbled & privileged to have worked with you all over the last 4 years. I hope to see you all in America's great outdoors very soon,” Salazar tweeted.
