The manufacture of manufactured stone veneseles (MVES) and other equipment, primarily for the transportation and production of cement, is scheduled to cease by the end of 2018, according to the American Iron and Steel Institute (AISI), the nation’s largest trade association.

The decision to shutter the industry comes on the heels of the AISI filing a lawsuit against the U.S. Export-Import Bank (EIB) and the U,S.

Steel Corporation (USSC) in an attempt to force the closure of the MVS manufacturing plants in Colorado and Illinois, the AisI said in a statement on Wednesday.

“This is yet another setback in a decades-long effort to dismantle and eliminate America’s MVS industry,” said Paul Bresch, director of the advocacy group’s Global Labor Program.

“These decisions are an affront to American workers, the safety of our communities and to our economy.”

The EIB and the USSC denied the allegations in a joint statement issued on Wednesday, saying that they were reviewing the matter.

“The USSC has long supported the construction of MVS facilities in the United States, including the construction in the Powder River Basin of the largest cement production facility in the world, and we remain committed to supporting these efforts,” they said.

“We are reviewing the EIB’s complaint and will respond to it in due course.”

The AISi is calling on the U and the AIG to negotiate a new deal on the MVES industry, citing the $6 billion annual economic impact the industry generates and the significant health, environmental and social costs.

The industry was born during the Cold War era as the primary method of transporting cement, and the manufacturing process uses millions of tons of steel, cement and concrete a year.

In recent years, the industry has expanded into new markets, such as the energy and transportation industries, and is also growing in the U; however, the current U.A.E. plan aims to close the manufacturing of MVES by 2035.

The manufacturing of the stone venaes has been the backbone of the American economy since the mid-1930s, and its decline has led to a reduction in the number of workers and an erosion of the local economy, the group said. 

“With the closure and loss of the manufacturing workforce, the overall American economy will suffer from a $1 trillion reduction in employment,” Bresche said.

In a separate statement, the EI said that the MVAB, which regulates the transportation of cement across the country, had “acted in a manner inconsistent with its statutory mandate” and had failed to take action on a number of matters.

“In its final decision, the U S. Steel Corp. and the EIG have made clear that they do not intend to continue to operate MVS factories in the US.

We urge them to withdraw this proposal to shutter MVS production and all of the remaining MVS operations in the country,” the group added. 

MVS manufacturing is the third-largest industry in the AIA, but the group says it is “extremely concerned” about the state of the industry.

The group also noted that the EIU has not provided enough details on how the industry will be impacted by the decision to close, or whether the jobs would be lost, to ensure the public and the industry have a fair and complete understanding of what’s happening.

The AIG did not immediately respond to a request for comment.
