The US Department of Justice filed a civil suit Monday against two companies that operate major highway construction projects across the country, accusing them of committing fraud, breach of contract, and other violations.
The companies, which include Steel Construction, Alston Construction, and Global Construction, were sued by the US Environmental Protection Agency, which alleged they failed to comply with federal law and the Clean Air Act and that the companies were intentionally ignoring environmental regulations.
The government is seeking damages for the violations, which allegedly happened between 2008 and 2016, the EPA said in a statement.
The lawsuit also alleges the companies violated federal civil rights laws, including the National Environmental Policy Act.
“Steel Construction and Alston Contractors were the primary producers of steel for many major federal highway projects,” the EPA statement said.
“They committed fraud, breached contract, lied to federal regulators, and engaged in conduct that would have caused harm to the environment if the companies had been operating in compliance with applicable environmental law and regulations.”
The EPA also accused the companies of failing to disclose to federal agencies that they had falsified environmental reports.
The companies are not named in the lawsuit.
Steel Construction did not immediately respond to a request for comment.
The EPA said it was “investigating and vigorously defending” the lawsuit against the two companies.
