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, establishing stricter landfill safety, monitoring, and notification protocols across California. The legislation aims to address public health concerns regarding toxic emissions and odor, particularly for communities living near active landfill fires.
Why it matters
The laws were passed in direct response to the ongoing health crisis caused by the 90-acre underground fire at the Chiquita Canyon Landfill. By mandating public transparency and stricter oversight, the state aims to better protect respiratory health in surrounding areas like Val Verde and Castaic.
The new legislation mandates public online access to methane emissions data and creates a specific fund for subsurface fire mitigation. These regulatory changes respond to current monitoring challenges at sites like the Chiquita Canyon Landfill, where the underground fire may burn for up to 20 years.

The details
The new laws require earlier notification and expanded monitoring for subsurface elevated temperature events, which can lead to hazardous air quality. The legislation mandates improved coordination between state, local, and public health agencies to track emissions and manage site safety. Furthermore, the state can now enforce daily penalties of up to $100,000 to ensure compliance with these new landfill safety standards.

Health Landscape
This legislation marks a shift in how California manages public health risks associated with landfill emissions. It establishes the Landfill Subsurface Fire Mitigation Community Fund to provide targeted support to areas facing long-term exposure to toxic fumes.
Residents near affected sites should monitor local air quality reports and consult their doctor about managing respiratory symptoms related to environmental odors. The new transparency requirements for methane emissions data will allow residents to better track local air conditions starting in 2027.
The takeaway
The new state laws aim to mitigate long-term health risks from subsurface fires through stricter oversight and transparency. If you live in an affected area, track local air quality alerts and discuss any worsening respiratory symptoms with your physician.
