Lodi Chrome <br />Inspection Rep <br />I observed a drum container situated near the caustic cleaning tank that was partially <br />covered by a small tarp. Mr. Mason lifted the tarp and I observed that the container <br />held a dark colored liquid. Mr. Mason informed me that the container held zinc cyanide. <br />The zinc cyanide container was situated in close proximity, within two feet, to a second <br />yellow colored container. Mr. Mason said that the yellow container held nitric acid used <br />for parts cleaning. I observed that there was no berm or other device on the floor that <br />separated the two containers from each other. I noted that there were white colored <br />crystals around the base of the container, which Mr. Mason had identified as containing <br />nitric acid. Cyanide and nitric acid are incompatible hazardous waste and if mixed <br />together may form toxic hydrogen cyanide gas. <br />California Code of Regulations, title 22, section 66265.177(c) requires container of <br />hazardous waste which are incompatible with any other waste or material stored nearby <br />in other container, tanks, or waste piles to be separated by a berm or other device. <br />Monitoring data collected by DTSC staff on January 18, 2007, indicates that the <br />corrosive hazardous waste (pH less than 1.0) is being stored near cyanide compounds <br />without having a separate berm or other device. Lodi Chrome has violated California <br />Code of Regulations, title 22, section 66265.177(c) in that reactive hazardous waste, <br />cyanide crystals, cooper cyanide tank and zinc cyanide container is stored in the same <br />area which is not separated by a berm as acidic corrosive hazardous waste. This <br />violation is being cited as a Class I violation in section V of the inspection report. <br />Photo 3A- Zinc cyanide container is stored adjacent to a nitric acid container <br />7of11 <br />
