SUPERIOR, WI -- Some crews are back to work at Superior's Husky Refinery after COVID-19 put the rebuild project on hold.
Husky spokespeople say a number of contractors were temporarily laid off when the project was paused in March.
Now, the company has resumed some rebuild work.
Essential workers are also on-site staffing terminals that supply gas and diesel and maintaining the wastewater treatment plant.
Spokespeople say they have safety precautions in place including social distancing and sanitizing.
The rebuild comes after the 2018 explosion and fires at the refinery caused serious damage and thousands across the Twin Ports to evacuate.
No one was killed, but 27 workers were hurt.
