PROPOSITION 65 (Prop 65) Compliance Program

California Health & Safety Code, Chapter 6.5, Section 25180.7, requires any Designated Government Employee (DGE) who obtains information in the course of their official duties regarding an illegal or threatened illegal discharge of hazardous waste to report this within 72-hours to the Board of Supervisors and the Health Officer.

The Director of Health Services (DHS) designated the Health Hazardous Materials Division (HHMD) of the Los Angeles County Fire Department, as the repository for Prop 65 disclosure notification reports for the County Health Officer.  HHMD will investigate all disclosure notification reports to determine if the discharge meets the criteria and is reportable under Prop 65.

HHMD developed the following Prop 65 – Criteria for Reporting Discharges or Threaten Discharges for DGE’s.

  • The discharge must be an illegal discharge or threatened illegal discharge of hazardous waste within the geographical area of your jurisdiction. The discharge may be either accidental, intentional and/or the result of negligence.

  • Discharge required or threatens to require evacuation of persons by an official agency.
  • Discharge contaminated domestic water supplies in levels exceeding State Drinking Water Action Levels (AL) or Maximum Contaminant Levels (MCL).
