The EPA has reminded its employees that the agency’s budget for fiscal 2018–the Trump administration is proposing a 31 percent cut in funding, the largest reduction among any agencies specified in the initial budget plan–is not yet final and has asked them to continue going about their work.

The budget plan unveiled last week projects a cut of 3,200 positions, about a fifth of the agency’s workforce, setting off alarms among employees, many members of Congress and outside interest groups.

A memo to staff from acting deputy administrator Mike Flynn said that “it’s important for all of us to remember several things. First, we are in the early stages of a long budget development process, and funding levels will not be finalized until Congress acts.

“Second, your work — the mission of the agency — is very important, and it’s critical that you continue to focus on the important work you do. And finally, remember you are part of a strong EPA team, one that has worked together to accomplish great things in the past and will continue to do so in the future. I am very proud to be one of your colleagues, and thank you again for your continued dedication and hard work,” he wrote.
