In plain language

The bill requires regulations for lead and asbestos testing after wildfires.

AB 1642 mandates that the Department of Toxic Substances Control create regulations and guidance for testing and cleaning up lead and asbestos contamination after wildfires. Additionally, it includes guidance on indoor air quality following smoke damage.

What this means for you
  • Workers: Workers involved in cleanup and restoration efforts will have defined standards to follow for handling hazardous materials.
  • Families: Families may benefit from clearer safety regulations regarding hazardous materials in their homes post-wildfire.
  • Environment: This means the environment will have more specific guidelines to ensure safe cleanup after wildfire incidents.

Summary

Existing law establishes the Department of Toxic Substances Control, which regulates the handling and management of hazardous waste and hazardous materials, and establishes the Office of Environmental Health Hazard Assessment and the State Air Resources Board. Existing federal law sets action levels for lead in dust and emission standards for asbestos, and existing state law sets workplace standards for asbestos. Existing law authorizes local health officers to take specified actions to protect public health and establishes procedures for the remediation of certain contaminated properties. This bill would require the Department of Toxic Substances Control, in consultation with the Office of Environmental Health Hazard Assessment and other relevant coordinating agencies, on or before December 31, 2028, to develop and adopt regulations pertaining to lead and asbestos testing, remediation, and restoration after a wildfire and, on or before December 31, 2029, to develop and publish guidance pertaining to specified other contaminants, as provided. The bill would require the State Air Resources Board, on or before December 31, 2028, to develop and publish guidance on indoor air contaminants following residential smoke damage from a wildfire, as provided. The bill would provide that, until the adoption of the regulations and guidance, specified lead and asbestos standards shall apply for wildfire-caused lead and asbestos remediation, as provided. The bill would require the department, in collaboration with the State Department of Education and other relevant state agencies, no later than July 1, 2028, to develop advisory, nonregulatory guidance for schools after a wildfire, as provided. The bill would exempt the regulations and guidance from the Administrative Procedure Act. The bill would become operative only if AB 1795 of the 2025–26 Regular Session is enacted and takes effect on or before January 1, 2027.​​​​​​​​​​​​​​​​​​​​​​​​​
