The Environmental Protection Agency has issued a new, more detailed plan for laying off 25 percent of its employees and scrapping 56 programs including pesticide safety, water runoff control, and environmental cooperation with Mexico and Canada under the North American Free Trade Agreement.

At a time when the agency is considering a controversial rollback in fuel efficiency standards adopted under President Obama, the plan would cut by more than half the number of people in EPA’s division for testing the accuracy of fuel efficiency claims by automakers.

It would transfer funding for the program to fees paid by the automakers themselves.

The spending plan, obtained by The Washington Post, offers the most detailed vision to date of how the 31 percent budget cut to the EPA ordered up by President Trump’s Office of Management and Budget would diminish the agency.

The March 21 plan calls for even deeper reductions in staffing than earlier drafts. It maintains funding given to states to administer waste treatment and drinking water. But as a result, the budget for the rest of EPA is slashed 43 percent.

The Trump administration says the EPA cuts reflect a philosophy of limiting federal government and devolving authority to the states, localities and, in some cases, corporations. But environmental groups say the Trump administration is answering the call of companies seeking lax regulation and endangering Americans’ air and water.

Former EPA official: Cuts would target most vulnerable communities

In a memorandum at the front of the March 21 document, the EPA’s acting chief financial officer David A. Bloom said the agency would now  “center on our core legal requirements,” eliminating voluntary activities on scientific research, climate change and education, and leaving other activities to state and local governments.

John Konkus, the agency spokesman said: “EPA will work with the President and Congress to redesign the way we do business to focus on achieving our core responsibilities – working with the states to ensure clean and breathable air, protecting water quality and investing in infrastructure, restoring our communities, ensuring timely review of chemicals and products to ensure safety for American families, all of which will have a positive impact on the environment and the economy.”

The $5.7 billion EPA budget will likely undergo massive rewriting by congressional lawmakers, but the document is a declaration of intent by the Trump administration — one that sets the agency fundamentally at odds with the environmental policies of the past eight years and in some cases nearly three decades.

Because of the sweeping cuts to scientific programs, the administrator’s own Science Advisory Board budget would be cut 84 percent. As the document explains, it would not need much money due to “an anticipated lower number of peer reviews.”

Reductions in research funds will curtail programs on climate change, water quality, and chemical safety, and “safe and sustainable water resources,” the document said.

Ken Kopocis, who headed EPA’s Office of Water in 2014 and 2015, said in an interview that the $165 million proposed cut to the agency’s nonpoint source pollution program would deprive farmers of critical funds to help curb agricultural runoff.

Several congressional Republicans have expressed support for reorienting the EPA’s mission, though lawmakers are likely to restore some of the funding.

Senate Environment and Public Works Committee Chairman John Barrasso (R-Wyo.) said in a statement Friday, “There is room to cut wasteful programs in EPA’s budget and at the same time, realign how taxpayer money is best allocated” by “giving states greater say in how they protect and manage their resources.”

In a recent interview, Sen. James M. Inhofe said he would like the department to focus on more traditional environmental concerns rather than addressing climate change.

“What I want them to do is to do what they are supposed to be doing – be concerned about the environment, the water, the air,” he said.    “I’d like to see an EPA there to actually serve people and make life better for them.”

Inhofe said some of the members of the scientific advisory boards scheduled for cuts had political biases. “They’re going to have to start dealing with science, not rigged science.”

But S. William Becker, executive director of the National Association of Clean Air Agencies, said eliminating the money for such advisory boards would inevitably compromise the agency’s science capabilities.

“This is becoming a self-fulfilling prophecy,” he said. “If they have less research and less peer review, they’re going to have less of a foundation on which to base human health-based air quality standards.”

The list of programs completely eliminated grew in the latest plan.

 A program to teach and monitor the proper handling of pesticides would be nearly eliminated, and instead rely fees paid by the industry.

Many people in industry might enlist lawmakers’ help in opposing those plans. CropLife America executive vice president Beau Greenwood, whose group represents U.S. pesticide manufacturers and distributors, said in an interview Friday that while the industry is “willing to put skin in the game to ensure the agency has sufficient funding” for reviewing its products, it already provides more than $46 million a year under the Pesticide Registration Improvement Extension Act.

“Extra fees on top of extra fees is something that we would oppose,” Greenwood said.

The latest EPA budget plan would abolish programs that study known environmental hazards including lead, poor indoor air quality, and radiation.

Others programs that help protect Americans from cancer would also face the axe — including  the $ 1.34 million indoor air radon program which works to protect the public against the invisible gas that is the leading cause of lung cancer among non-smokers. Radon kills 21,000 people annually, according to the EPA.

The EPA’s radiation program, currently funded at $2.34 million, which sets standards for safe levels of ionizing radiation in the environment caused by radioactive elements such as uranium, is also slated for elimination — but it is unclear how fully eliminating its activities is possible.

The document also recommends a $28.9 million cut in the enforcement of clean up projects for Superfund sites, places where hazardous materials require long-term response plans.

In each case, the budget document says that these programs can be eliminated because they do not represent core agency priorities or can be deferred to states.

The budget document also proposes the elimination of regional programs focused on restoring watersheds and coastal and marine habitats. These include programs for the Chesapeake Bay, the Gulf of Mexico, Lake Champlain, Long Island Sound, Puget Sound, San Francisco Bay, the Great Lakes, and South Florida.

The document notes that these are areas where EPA is working with localities to restore damaged ecosystems and watersheds. It says that EPA’s regulatory heft isn’t needed and that localities must take responsibility.

“In some ways, the common thread …. is, unless there’s an explicit legal mandate that EPA has to do something, that EPA shouldn’t be doing it,” said Stan Meiburg, a longtime EPA career employee who served as acting deputy administrator of the agency late in the Obama years.
