Should landfill operators be strictly liable for the costs of health disasters affecting local communities?
Governor Gavin Newsom has signed Assembly Bill 28 and Assembly Bill 2674 into law to address public health concerns stemming from landfill fires. These measures establish stricter safety protocols and mandate public access to methane emission data.
Why it matters
The legislation responds to the ongoing health crisis at the Chiquita Canyon Landfill, where residents have reported issues with toxic emissions and odors. The new mandates aim to improve agency coordination and ensure communities remain informed about air quality and safety risks.
The laws establish a new mitigation fund and authorize daily penalties of up to $100,000 for specific landfill violations. These measures directly address the 90-acre underground fire currently burning at the Chiquita Canyon Landfill.
