Industrial plumbing, heating, and air conditioning have been among the biggest losers under the Trump presidency.
The Trump administration has ordered the EPA to cut nearly a third of the agency’s funding.
The EPA says it has no choice but to close the remaining $30 billion in funding, which includes nearly $6 billion in appropriations for the Occupation Safety and Security Administration.
The agency has been running the agency since 1999, when President Bill Clinton created it.
The administration has been under scrutiny since last year, when a series of videos and other materials emerged that showed workers at the agency engaging in dangerous overtime practices.
The government watchdog group Citizens for Responsibility and Ethics in Washington (CREW) said the videos and materials, which included photos of dead and injured workers, exposed a culture of violence and intimidation that undermined safety and led to at least eight deaths.
In addition, the videos showed employees who had been fired or left with severance payments not being paid.
CREW filed a Freedom of Information Act request for the videos with the EPA and the agency responded with a series in October, detailing the agency efforts to address the safety concerns.
In a letter to CREW on Monday, the agency said the department is now reviewing its response and will provide a more detailed response in the near future.
A spokesman for the agency declined to comment on the response.
In the letter, the EPA said it is committed to ensuring the safety of employees in its safe work environment and to working collaboratively with the private sector to improve workplace safety.
But the letter noted that the agency was unable to comment as of Monday.
The new rules are scheduled to go into effect on December 5.
