President Trump picked former Oklahoma Attorney General Scott Pruitt to lead the U.S. Environmental Protection Agency (EPA) as its administrator in February of last year. The Trump administration has ushered in a new era—one of rolling back regulations that are unnecessary and duplicative. According to the White House, the Trump administration has rolled back 1,579 planned regulatory actions in its first year. It estimates that to be a lifetime net savings of $8.1 billion.

It’s not difficult to see the EPA’s actions on regulatory reform this past year as the tip of the spear for the Trump administration’s regulatory rollback efforts. It looks tough—for every one regulation the EPA has put forward, about 18 have been rolled back. The EPA has faced a number of challenges and was dealt some setbacks.
