According to Mr. Chris Delaney, Marathon Petroleum, an estimated 4oz of Hydrofloric Acid (HF) was released into the oily water sewer system during the planned demolition of a blind flange in a pipe leading from the HF Alkylation Unit. Pipe was isolated from all other sources, source of the acid secured, and disconnected prior to installation.
