Excerpts from the Chicago Tribune: The Park Ridge fire marshal issued a citation on Thursday for failing to inform the fire department about the storage of hazardous materials at a site before it caught fire. Firefighters responded to a large blaze that engulfed the former Harvey’s Marathon gas station located at Northwest Highway and Oakton Street. The property owner did not post warning signs or notify the fire department that 45 tons of calcium peroxide were stored inside and around the building. The citation carries a $500 fine. The calcium peroxide was intended for cleaning up soil contamination on the property, which had previously operated as a gas station for many years. The site has been vacant since approximately 2013. Park Ridge officials identified the property owner as Raza Holdings LLC. The fire department classified calcium peroxide as a hazardous material that contributed to the rapid spread of the fire, resulting in two firefighters suffering minor burns. The Park Ridge Fire Department and other responding agencies are expected to seek reimbursement for equipment damage and labor costs. The cause of the fire remains under investigation. Cleanup efforts continued on Friday, with oversight from the Illinois Environmental Protection Agency and the Metropolitan Water Reclamation District. A plastic-lined sand berm was installed on the property on Thursday, and cleanup was expected to continue through the weekend. While the IEPA does not regulate the storage of calcium peroxide, local municipalities may have specific requirements. Any remaining material that wasn’t destroyed in the fire cannot be used for the planned soil decontamination efforts. Dongguan Anding Technology Manufacturing Co., Ltd , https://www.cn-moulds.com
