CHS' proposed nitrogen fertilizer plant in Spiritwood, North Dakota, received an air permit which will allow construction on the project to start.
The permit, issued by the North Dakota Department of Health, allows CHS to begin construction within the next 18 months and allows consequential air emissions during the construction and operation phases of the plant.
CHS said numerous permit applications have been filed over the last year and many permit approvals are anticipated as part of the overall project timeline. But last month, CHS delayed a formal decision on whether it would proceed with the planned nitrogen plant.
"CHS continues to review all project parameters and options prior to making any final decisions," a CHS spokeswoman said. "There currently is no timetable for a next decision point."
Costs have increased beyond the initial projection of $1.2bn when the project was first announced in 2012 and are now estimated closer to $2bn. The project would likely produce around 2,200 st/day ammonia of which most would be further upgraded to urea and UAN.
