FREMONT (AP) -- Federal regulators have issued a $3.9 million fine against a Pennsylvania company with an Ohio plant that makes tanks to store and transport anhydrous ammonia used by farmers.
The U.S. Department of Transportation says the company's tanks didn't meet federal hazardous materials safety standards.
American Welding & Tank in Fremont makes the tanks. The company is based in Mechanicsburg, Penn.
A message seeking comment was left with the company Friday.
Regulators say they found problems after looking at the company's welding practices and safety records.
They say the fine stems from manufacturing and selling unsafe tanks that hold the potentially dangerous anhydrous ammonia that's used as an agricultural fertilizer.
