The budget for the Environmental Protection Agency could reportedly be reduced by roughly 25 percent, costing the agency about 3,000 jobs.

President Trump has said he plans to pay for billions of dollars more for the military by cutting spending on domestic agencies and departments. Trump plans to submit his budget to Congress the week of March 13.

The Associated Press reportedly obtained a copy of a draft of the EPA’s budget proposal from the Office of management and Budget. The cuts would result in a 19 percent decrease in staff at the agency.

A spokeswoman for the EPA declined to comment, but a top official said in an internal memo that EPA leaders "will do everything in our power to protect our ability to support the mission of the agency in protecting human health and the environment."

A copy of the memo from Acting Assistant Administrator Donna Vizian was obtained by the AP.

Vizian said she could not verify news media accounts, but said any proposed cuts were just the start of a lengthy budget process. A final plan is subject to congressional approval, which likely is months away at the earliest.

Former EPA Administrator Gina McCarthy called the proposed budget "a fantasy" that ignores the EPA's mission to protect public health.

"It shows the Trump administration doesn't hold the same American values for clean air, clean water and healthy land as the vast majority of its citizens," McCarthy said in a statement. "Our health comes before the special interests of multibillion-dollar industries."

The EPA is now under the leadership of Scott Pruitt, a former state attorney general for Oklahoma, who has questioned the scientific consensus that human activities are contributing to global warming and joined lawsuits against the agency's emission curbs.

The Trump administration also would cut funding for the National Oceanic and Atmospheric Administration by 17 percent, The Washington Post reported Friday, citing a four-page memo from OMB that the newspaper obtained. The scientific agency, which is part of the Commerce Department, studies changes in climate, weather, oceans and coasts.

The draft proposal for the EPA would cut its annual budget from about $8.2 billion to $6.1 billion. Proposed cuts include reducing the climate protection budget by nearly 70 percent to $29 million, the Great Lakes Restoration Initiative by 97 percent to $10 million and environmental justice programs by 79 percent to $1.5 million.

The proposal would all but eliminate funding for the Great Lakes Restoration Initiative, a wide-ranging cleanup of the world's largest surface freshwater system that has deep bipartisan support across the eight states adjacent to the lakes, from Minnesota to New York. The program has received around $300 million annually from the federal budget during former President Barack Obama's tenure -- more than $2.2 billion in all. Under the Trump proposal, it would get only $10 million.

Sen. Debbie Stabenow, D-Mich., described the proposed cut as "outrageous.”

"This initiative has been critical to cleaning up our Great Lakes and waterways, restoring fish and wildlife habitats, and fighting invasive species, like Asian carp," Stabenow said. "I call on President Trump to reverse course on these harmful decisions."

The Heartland Institute, a conservative think tank, said the proposal didn't go far enough.

"If Donald Trump and Scott Pruitt are serious about ending the national scandal that is EPA, they will accept nothing less than a 20 percent cut this year and make this year's cut the first step in a five-year plan to replace the organization," said Joseph Bast, the group's president.
