ACE IN THE HOLE: More than 70 Democratic lawmakers from both chambers have joined a suit challenging the Trump administration for rolling back Obama-era power plant regulations.

The Affordable Clean Energy (ACE) rule finalized by the Environmental Protection Agency (EPA) in August scraps former President Obama’s Clean Power Plant (CPP) rule. Lawmakers in the House and Senate filed separate amicus briefs in opposition to the rule late Friday.

The ACE rule aims to give states more time and authority to decide how to implement the best new technology to ease net emissions from coal-fired plants. The rule does not set any standards to cap those emissions.

Critics argue ACE allows for only modest pollution controls at power plants, a feature that, if upheld, could hamstring future administrations from addressing climate-altering pollution through regulation under the Clean Air Act.

“We will continue to oppose this administration’s willful misinterpretations of environmental laws that seek to justify rolling back critical public health protections and undermine future administrations’ ability to safeguard our environment and the American people,” they wrote.

The Trump EPA had long argued the Clean Power Plant rule was too broad, creating an undue burden on industry.

Reached for comment Monday, the agency said, "EPA looks forward to defending the Affordable Clean Energy Rule before the court."

RANCH ADDRESSING: A group of ranchers sued the Trump administration Monday over a rollback to an Obama-era water rule they argue is still too strict.

At stake is the Navigable Waters Protection Rule, a rule President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE repeatedly promised to deliver for farmers who complained previous policy left huge swaths of their land subject to federal oversight.

But the suit from the New Mexico Cattlemen’s Association argues the latest Trump replacement is both too strict, violating “the Constitution, the Clean Water Act, and Supreme Court precedent,” and lacking key definitions.

“The act does not define ‘navigable,’” they argued, leaving it unclear whether it falls to the Environmental Protection Agency (EPA), the Army Corps of Engineers or the state to regulate various water bodies.

But they said the rule “provides no guidance or criteria to the agencies” to sort out who will oversee what.

Environmental groups, who have likewise pledged to sue over the rule, see it differently.

“This is not just undoing the clean water rule promulgated by the Obama administration. This is going back to the lowest level of protection we’ve seen in the last 50 years,” Collin O’Mara, president and CEO of the National Wildlife Federation, said when the rule was announced in January. “This is a staggering rollback.”

S-PARKING CONTROVERSY: House Democrats are questioning the Trump administration over its plan to reopen "as rapidly as possible" certain national parks that closed amid concerns over the coronavirus pandemic.

Last week, President Trump said that his administration would begin to reopen national parks and public lands. Interior Secretary David Bernhardt said in a tweet that the president told him to “promptly restore access to our magnificent national parks.”

Critics have expressed concern that allowing crowds to gather at the parks could contribute to the spread of the coronavirus.

Democrats on the House Natural Resources Committee questioned the Interior Department in a Monday letter about its timeline and criteria for opening parks and public lands.

“In spite of these concerns and the rising number of confirmed cases of coronavirus in the U.S., the administration has continued to encourage public lands visits without implementing clear protocols to ensure the health and safety of visitors and employees,” the lawmakers wrote.

“In the face of this unprecedented crisis, it is crucial that any decisions to reopen national parks and other public land sites prioritize the health and safety of visitors, employees, and local communities and that they are guided by directives from public health experts and local officials,” they added.

In response to the letter, Interior spokesperson Conner Swanson told The Hill in an email that "the health and safety of our visitors, employees, volunteers, and partners continues to be our highest priority."

"Every operational change made at a national park or on our public lands during this pandemic has been led by federal, state and local public health officials. In following current federal, state and local public health guidance, the NPS [National Parks Service] continues to examine each facility function and service, ensuring our actions to increase access are done in a safe manner,” Swanson added.

Bernhardt separately said in a statement over the weekend that his department and the National Park Service “are working to reopen the American people’s national parks as rapidly as possible.”

Loan it in...Treasury Secretary Steve Mnuchin said this weekend that the Trump administration is considering loans for oil companies.

“We’re looking at it carefully. The secretary of Energy and I are studying it and we’re looking at it very carefully,” Mnuchin said while appearing on “Fox News Sunday.”

He stressed that the administration wouldn’t give shareholder bailouts to oil companies or any other companies.

“The president has said no bailouts to any companies, whether that was airlines or oil companies,” the Treasury chief said.

Biden told Politico he envisions a “trillion-dollar infrastructure program that can be implemented really rapidly,” as well as “dealing with environmental things that create good-paying jobs.”

On his list of pet projects are investments in light rail, clean drinking water and deploying half a million electric vehicle chargers on the nation’s highways.
