Operator stated that laser filters <br /> are disposed of in the garbage. <br /> -Metal dust from laser cutting machines observed on the ground and inside scrap metal recycling bins. Operator <br /> stated metal dust are recycled by a scrap metal recycler. <br /> Note: Operator stated metal dust comes from Carbon Steel Mebac and Aluminum Alloy metals. Safety Data Sheet <br /> for aluminum alloy stated "in the form of particulates may be reactive and its hazardous characteristics should be <br /> determined prior to disposal." <br /> REGULATION GUIDANCE: Any person who generates a waste shall determine if the waste is a hazardous waste <br /> as specified in Title 22 California Code of Regulations(CCR). There are wastes that are listed as hazardous <br /> wastes. There are wastes that exhibit one or more of the hazardous waste characteristics:toxic, corrosive, reactive <br /> or ignitable. Metal particles 100 microns or smaller in size must be handled and disposed of as hazardous waste if <br /> the metal is determined to be a hazardous waste. Metal particles larger than 100 microns in size can be recycled as <br /> scrap metal. <br /> CORRECTIVE ACTION: Immediately stop recycling metal dust as scrap metal and disposal of laser filters in the <br /> garbage, make a hazardous waste determination for each waste , and manage it according to Title 22 CCR. Use <br /> Safety Data Sheets (SDS),waste sampling and test results or other knowledge to make your hazardous waste <br /> determination. Waste testing must be done using methods specified in Title 22 CCR including Title 22 CCR <br /> sections 66261.20-24. <br /> Submit a statement and supporting documentation with your hazardous waste determination. Demonstrate current <br /> storage and labeling for wastes determined to be hazardous wastes. Provide disposal records for wastes <br /> determined to be hazardous wastes and stored longer than the number of days specified in Title 22 CCR for your <br /> hazardous waste generator status. <br /> This is a minor violation. <br /> FA0010031 PR0514135 SCO01 09/25/2020 <br /> EHD 22-01 Rev.9/16/2020 Page 4 of 6 Small Quantity Hazardous Waste Generator OIR <br /> 1868 E.
