The president-elect and his vice president are proposing to slash the Environmental Protection Agency’s enforcement funding by $8.3 billion.
The cuts would be $4.5 billion lower than President Barack Obama’s proposed $14.2 billion reduction.
The budget cuts would also eliminate several enforcement programs, including the Center for Biological Diversity’s Endangered Species Program.
The Trump administration is also proposing to cut the U.S. Fish and Wildlife Service’s enforcement mission budget by 15 percent, from $2.2 trillion to $1.9 trillion.
The Interior Department’s budget, which covers the agencies that deal with water, air, wildlife and fisheries, would also be slashed by $1 billion, from nearly $6.8 billion to $5.2 million.
The administration’s proposal includes $2 billion in cuts for the Federal Emergency Management Agency, which provides disaster relief and response, but that would not be offset by the proposed cuts.
“In addition to the devastating cuts we are proposing today, we will be cutting $2 million from FEMA’s budget to ensure that the Federal Government can keep funding our first responders, while protecting our water resources,” Pruitt said in a statement.
“We are also eliminating the Office of Management and Budget’s office to improve transparency and reduce waste and abuse.”
Trump has promised to reverse many of the EPA’s actions.
For instance, he has called for EPA to stop regulating carbon dioxide, a greenhouse gas that contributes to global warming.
In April, he ordered EPA to review all proposed regulations, including ones related to ozone pollution, and to begin an environmental impact statement process.
EPA’s Office of Water is also scheduled to review regulations affecting water quality, and the Environmental Defense Fund’s Clean Water Rule would have been scrapped, as would a rule requiring that all coal ash ponds be closed.
EPA has also been criticized for its climate change regulations, which it announced last year.
EPA said it was reviewing the rule but that the administration “is confident that its review will ultimately identify significant mitigation measures that will address these concerns.”
It is also seeking to repeal a requirement that EPA implement the Clean Power Plan, a landmark carbon emissions reduction law that was finalized in December 2015.
The proposed EPA cuts would save the agency about $3.6 billion, according to the Congressional Budget Office.
EPA declined to comment on the Trump administration’s proposed cuts, but the agency has been accused of being too soft on greenhouse gases.
A 2015 study from the American Council for Capital Formation, a conservative think tank, found that the proposed EPA budget cuts could hurt U.K. coal production, particularly in the heart of the country.
“The Trump administration may be the first major U.N. agency to seek to reverse Obama-era climate policies, but it has also signaled that it will seek to further undermine EPA’s ability to enforce existing federal rules,” the study said.
“It is hard to imagine that such a change would have a significant impact on U.s. coal industry,” said Scott D. Thayer, a senior policy analyst with the Center on Budget and Policy Priorities.
“At this stage, EPA’s budget would be the most substantial reduction since the Bush administration.”
