Trump Eases Pollution Controls On Streams And Wetlands

By      Coral Davenport

WASHINGTON — The Trump administration on Thursday will finalize a rule to strip away environmental protections for streams, wetlands and other water bodies, handing a victory to farmers, fossil fuel producers and real estate developers who said Obama-era rules had shackled them with onerous and unnecessary burdens.

From Day 1 of his administration, President Trump vowed to repeal President Barack Obama’s “Waters of the United States” regulation, which had frustrated rural landowners. His new rule, which will be implemented in the coming weeks, is the latest step in the Trump administration’s push to      repeal or weaken nearly 100 environmental rules and laws   , loosening or eliminating rules on climate change, clean air, chemical pollution, coal mining, oil drilling and endangered species protections.

Mr. Trump, whose own real estate and golf-course empires almost certainly ran into the Obama rule, has called the regulation “horrible,” “destructive” and “one of the worst examples of federal” overreach.

“I terminated one of the most ridiculous regulations of all: the last administration’s disastrous Waters of the United States rule,” Mr. Trump told the American Farm Bureau Federation’s annual convention in Texas on Sunday, to rousing applause. He added, “That was a rule that basically took your property away from you.”

His administration had completed the first step of its demise in September with the      rule’s repeal   .

His replacement on Thursday will complete the process, not only rolling back 2015 rules that guaranteed protections under the 1972 Clean Water Act to certain wetlands and streams that run intermittently or run temporarily underground, but also relieves landowners of the need to seek permits that the Environmental Protection Agency had considered on a case-by-case basis before the Obama rule.

It also gives President Trump a major policy achievement to bring to his political base while his impeachment trial continues.

“Farmers coalesced against the E.P.A. being able to come onto their land, and he’s delivering,” said Jessica Flanagain, a Republican strategist in Lincoln, Neb. “This is bigger news for agricultural producers than whatever is happening with the sideshow in D.C.,” she added.

The new water rule will remove federal protections from more than half the nation’s wetlands, and hundreds of thousands of small waterways. That would       for the first time in decades allow landowners and property developers to dump pollutants such as pesticides and fertilizers directly into many of those waterways, and to destroy or fill in wetlands for construction projects.

“This will be the biggest loss of clean water protection the country has ever seen,” said Blan Holman, a lawyer specializing in federal water policy at the Southern Environmental Law Center. “This puts drinking water for millions of Americans at risk of contamination from unregulated pollution. This is not just undoing the Obama rule. This is stripping away protections that were put in place in the ’70s and ’80s that Americans have relied on for their health.”

Mr. Holman also said that the new rule exemplifies how the Trump administration has      dismissed or marginalized scientific evidence   . Last month, a government advisory board of scientists, many of whom were handpicked by the Trump administration,      wrote that the proposed water rule “neglects established science.”

But farmers and fossil fuel groups supported the change.

“This is a big win for farmers, and this is the president delivering what he promised,” said Donald Parrish, senior director of regulatory affairs for the American Farm Bureau Federation, which had lobbied for years to weaken the Obama administration’s water rules.

Karen Harbert, chief executive officer of the American Gas Association, said the new rule “would restore the proper balance between federal and state regulation of our nation’s waters and protect our rivers, streams and lakes without stifling construction of important infrastructure.”

Legal experts say that Mr. Trump’s replacement rule would go further than simply repealing and replacing the 2015 Obama rule — it would also eliminate protections to smaller headwaters that have been implemented for decades under the 1972 Clean Water Act.

“This is rolling back federal jurisdiction of the Clean Water Act further than it’s ever been before,” said Patrick Parenteau, a professor of environmental law at Vermont Law School. “Waters that have been protected for almost 50 years will no longer be protected under the Clean Water Act.”

That could open millions of acres of pristine wetlands to pollution or destruction, and allow chemicals and other pollutants to be discharged into smaller headland waters that eventually drain into larger water bodies, experts in water management said. Wetlands play key roles in filtering surface water and protecting against floods, while also providing wildlife habitat.

Ean Thomas Tafoya, a Colorado-based clean water activist with the group GreenLatinos, said the new rule could harm the quality of the water in the Colorado River, which supplies water to 17 western states.

“We are a headwater state,” he said. “This rollback will affect almost every single stream that flows into the Colorado River.”

Mr. Tafoya said about 90 percent of the streams that supply the Colorado River run only after rainfall or snowmelt. Under the new Trump water rule, many of those streams will not qualify for federal pollution protection. But Mr. Tafoya said pollutants such as chemical pesticides that end up in those dry stream beds could nonetheless be swept into larger bodies of water when the streams begin running after the spring thaw of mountain snow.

“The toxics or poisons that lie dormant will still be there when the streams are reactivated,” he said. “They will still get into the larger bodies of water.”

The Obama rule protected about 60 percent of the nation’s waterways, including large bodies of water such as the Chesapeake Bay, Mississippi River and Puget Sound, and smaller headwaters, wetlands, seasonal streams and streams that run temporarily underground. It limited the discharge of pollutants such as fertilizers, pesticides and industrial chemicals into those waters.

The new rule, written by the Environmental Protection Agency and the Army Corps of Engineers, will retain federal protections of large bodies of water, as well as larger rivers and streams that flow into them and wetlands that lie adjacent to them. But it removes protections for many other waters, including wetlands that are not adjacent to large bodies of water, some seasonal streams that flow for only a portion of the year, “ephemeral” streams that only flow after rainstorms, and water that temporarily flows through underground passages.

Legal experts say that Mr. Trump’s replacement rule would go further than simply repealing and replacing the 2015 Obama rule — it would also eliminate protections to smaller headwaters that have been implemented for decades under the 1972 Clean Water Act.

“This is rolling back federal jurisdiction of the Clean Water Act further than it’s ever been before,” said Patrick Parenteau, a professor of environmental law at Vermont Law School. “Waters that have been protected for almost 50 years will no longer be protected under the Clean Water Act.”

“The toxics or poisons that lie dormant will still be there when the streams are reactivated,” he said. “They will still get into the larger bodies of water.”

Government scientists, even those appointed by the Trump administration, say those concerns are justified. The E.P.A.’s Scientific Advisory Board, a panel of 41 scientists responsible for evaluating the scientific integrity of the agency’s regulations, concluded that the new Trump water rule ignores science by “failing to acknowledge watershed systems.” They found “no scientific justification” for excluding certain bodies of water from protection under the new regulations, concluding that pollutants from those smaller and seasonal bodies of water can still have a significant impact on the health of larger water systems.

Those scientific findings, although they are not reflected in the administration’s policy, could still play a role in the fate of the new rule. Several state attorneys general are expected to join with environmental groups to sue to overturn the Trump water rule, and those groups are likely to cite those findings as evidence that the rule is not legally sound.

“The legal standing all has to do with whether you have a rational basis for what you’re doing,” said Mr. Parenteau. “And when you have experts saying you’re not adhering to the science, that’s not rational, it’s arbitrary.”
