General Motors (GM) is reportedly considering an increase in its truck engine production with a new engine plant in Ohio. The $175 million plant investment will add to the company’s existing DMAX plant in Moraine, Ohio, and will build the same diesel engines.

“We just need more engine production volume,” Dan Flores, GM spokesperson, told Dayton Daily News.

If GM moves forward with the plant, it could open in late 2020 and will employ more than 100 workers, Flores told the news outlet.

GM said it will continue to operate the DMAX plant and is looking to build the new facility in Brookville, Ohio. The automaker is already working with the state on an incentives package, which Flores said the decision to open the plant will depend on making the “best business case.”

Flores told the news outlet the plant would cover 251,000 square feet.

Shares of GM stock were down 3 percent as of 10:51 p.m. ET on Monday.
