U.S. President Donald Trump sits for an interview with Reuters in the Oval Office at the White House in Washington, U.S., February 23, 2017.

As reported by the New York Times, the administration's forthcoming budget proposal is expected to ramp up military spending by $54 billion, and impose steep cuts on non-military agencies.

E&E News got new details about the budget's likely impact on the EPA from sources informed about the plan. A 20% staff decrease would mean layoffs of 3,000 employees, and a $2 billion cut would reduce the EPA budget by about 25% from its current $8.1 billion. (For comparison, the 2016 Department of Agriculture budget was $140 billion, the State Department's was about $50 billion, and NASA's was about $18 billion. The Pentagon budget, which includes military spending, was $560 billion.)

About 74% of the EPA's annual budget funds grants to states, tribes, and government contractors for cleanup and preparedness efforts. The remainder goes to staff payroll, scientific studies, and other expenses.

Since 2010, the EPA has already decreased its operating budget by $2.1 billion — at the time, its expenses totaled $10.2 billion.

Trump's budget proposal, of course, would not immediately become law once released. Rather, it presents a framework that Congress can vote on.

According to E&E News, Gina McCarthy, the former EPA chief under Obama, said that if the Trump administration believes the budget won't hinder the EPA's mission to protect public health, it's a "fantasy."
