The Trump government has twice beaten environmental policy in the Obama era with a sustained setback aimed at numerous rules.
The Department of the Interior revealed plans to allow oil drilling on millions of hectares, which were closed to protect the meadow chicken.
And the Environmental Protection Agency (EPA) said it would end the rules on limiting carbon dioxide emissions from new coal-fired power plants.
The rollback continues, though the US strongly warns of the warning about climate change.
Internal Affairs documents indicate Thursday's order would protect the biting sausage while ensuring that conservation efforts do not hamper local economic opportunities.
The interior department plan is expected to be completed in 2019.
The Bockhuhn, a chicken-like bird known for its striking plumage and mating dances, has a habitat that includes portions of 10 states from California to the Dakotas.
However, less than half a million birds are still present, which makes the species almost threatened.
Nada Culver of The Wilderness Society said in a policy statement, "The sum of these changes can be more than the species can endure."
Meanwhile, on Thursday, the EPA started a plan to lift carbon emissions from new coal-fired power plants.
According to Reuters news agency, it is currently expected that only two new plants will be opened in the next four years, but the changes in the guidelines could provide the impetus for further construction.
The plan would allow new coal-fired power plants to emit up to 862 kg of carbon dioxide per megawatt-hour of electricity, replacing the current limit of 1,400 pounds.
The EPO also asks for public comments on the definition of "causes or contributes significantly to air pollution".
Commenting on politics in Washington, Deputy EPA Administrator Andrew Wheeler said, "We are revoking unfair burdens and balancing the competitive environment."
More about climate change
Last month, President Donald Trump rejected a report by his own government warning of the devastating economic consequences of the US for climate change.
"I do not believe it," said the Republican president to reporters.
Proponents of his policy welcome it as an overdue removal of the green ribbon that they claim is holding back companies.
The Columbia Law School's Sabin Center for Climate Change Law is pursuing the repeal of the Trump government's environmental regulations.
The current list currently contains more than 100 entries.
The Sabin Center is making repeated attempts by the Ministry of the Interior and other authorities to expand onshore oil and gas wells, including on public land.
It also points to repeated proposals to weaken the control of methane emissions – a highly effective greenhouse gas.
Romany Webb, Senior Fellow at Sabin Center, cited three more far-reaching actions that have been taken by this administration so far.
- The EPA and the National Highway Traffic Safety Administration (NHTSA) launched a proposal in August this year to mitigate greenhouse gas emissions and fuel consumption standards for light commercial vehicles. The proposal would increase vehicle emissions by around 713 million tonnes of carbon dioxide
- Also in August, the EPA proposed replacing and watering down the clean power plan, a key component of the Obama administration's climate action plan, which aims to cut carbon dioxide emissions from existing power plants by 30%
- In January of this year, the Ministry of Interior proposed to provide over 90% of the outer continental shelf for future oil and gas development. So far, 94% of the outer continental shelf was closed to drilling
