𝗕𝗨𝗥𝗡 𝗭𝗢𝗡𝗘 𝗛𝗔𝗭𝗔𝗥𝗗𝗦: EPA Safely Neutralizes Lithium Batteries at Topanga Toxic Waste Removal Site

On Friday, February 7, 2025, the U.S. Environmental Protection Agency (EPA) continued its extensive recovery operations in the aftermath of the Palisades Fire, focusing on the safe handling and disposal of hazardous lithium-ion batteries. Chris Myers, Federal On-Scene Coordinator at the EPA and a co-chair of the agency’s National Lithium-Ion Battery Emergency Response Task Force, provided an overview of the work being conducted at the Topanga Lithium Battery Toxic Waste Removal Site. The EPA's Lithium Battery Response Task Force had collected batteries from fire-damaged electric vehicles and residential energy storage systems throughout the burn zones in Pacific Palisades. These batteries, transported to the Topanga site in secure 55-gallon drums, underwent a critical safety and processing protocol to mitigate their hazardous potential. At the site, hazmat personnel in white protective suits, respirators, gloves, and hard hats conducted meticulous processing operations. Myers explained the multi-step process: in the field, unstable batteries were removed from vehicles and energy systems and placed into drums for safe transport. Once at the processing site, damaged batteries that had undergone thermal runaway were either crushed to eliminate any chance of further reaction or submerged in an electrolytic brine solution—saltwater—to safely discharge any remaining energy. Crushing rendered the batteries mechanically incapable of causing thermal runaway or explosions. “This operation ensures that these highly volatile batteries are stabilized and no longer pose a safety risk,” Myers said. “By safely discharging and mechanically neutralizing these batteries, we significantly reduce the potential for dangerous incidents.” The EPA’s efforts are part of the broader hazardous materials cleanup mission initiated following the catastrophic Palisades Fire. The fire, which ignited on January 7, 2025, consumed more than 23,000 acres and destroyed over 12,000 structures, displacing approximately 150,000 residents in Pacific Palisades, Malibu, and the San Fernando Valley. Despite challenges posed by high winds that grounded aerial firefighting efforts, the fire was contained following significant rainfall, which also brought concerns about mudslides and debris flow in the affected areas. The EPA’s ongoing work, alongside other government agencies and relief organizations, remains vital in ensuring the safe and efficient rebuilding of communities impacted by the disaster. By addressing hazardous materials like lithium-ion batteries, the agency is playing a crucial role in safeguarding public and environmental health during the recovery process.
