A. ANTIFREEZE (liquid) <br />General: Used antifreeze coolant is regulated as a California hazardous waste because: <br />Ethylene glycol, the most common ingredient in antifreeze, can be toxic to <br />animals2. <br />• Antifreeze can dissolve metals commonly found in engine components as it <br />circulates through a cooling system. These dissolved metals, such as lead, <br />copper, and zinc can cause the used antifreeze to be hazardous if they are <br />present at concentrations greater than or equal to the regulatory limits 3 <br />Even propylene glycol -based antifreeze is still expected to contain dissolved <br />metals at concentrations greater than hazardous waste regulatory thresholds. <br />• Most antifreeze wastes are recyclable hazardous wastes. Recovered <br />antifreeze/water mixtures should be reused whenever possible, and if reuse is <br />not possible, they should be recycled through either an on-site or off-site <br />recycler. <br />Empty antifreeze containers should be rinsed with water and used to "top off' <br />radiators in vehicles when replacing antifreeze. Then once the containers are <br />empty, they can be disposed of as a non -hazardous waste or recycled by <br />following the general handling method described in Chapter V-A. The <br />disposal of waste antifreeze -saturated solid is addressed in Chapter V-A. <br />Handling and • See Appendix IV -A for further information pertaining to hazardous waste <br />Packaging: handling and packaging. Antifreeze liquids that will be reused or recycled <br />should be stored in non -removable head drums. <br />Storage: • Reuse: Used antifreeze that will be reused without processing is not a waste <br />and should not be stored in a Hazardous Waste Storage Area or a Workplace <br />Accumulation Area. <br />22 CCR 66261.24 (a)(8) <br />22 CCR 66261.24(a)(1-2) <br />IV -2 OPG&E July 1997 <br />
