DELAWARE CITY, Del. (AP) - Officials say a Delaware City Refinery unit is using backup pollution control after a malfunction that sent a dark plume of smoke billowing from a stack at the plant.

A Department of Natural Resources and Environmental Control alert says the problem at PBF Energy's refinery began early Tuesday and involves an energy-recovery and pollution-control system linked to a coker, which controls emissions.

State officials say several chemicals, including ammonia, hydrogen sulfide and hydrogen cyanide are being released. They say the emissions will continue until the system is back on line, which could occur on Friday.

PBF Energy says air monitoring showed "no offsite impact."
