Proposition 65

Most Current Proposition 65 No Significant Risk Levels (NSRLs) Maximum Allowable Dose Levels (MADLs)

Safe harbor levels, which include No Significant Risk Levels (NSRLs) for cancer-causing chemicals and Maximum Allowable Dose Levels (MADLs) for chemicals causing reproductive toxicity, have been established for many of the chemicals listed under Proposition 65. Exposure levels and discharges to drinking water sources that are below the safe harbor levels are exempt from the requirements of Proposition 65. A document that provides the status of OEHHA’s adoption or development of NSRLs and MADLs is available below.

Choose a link below to download the documents as PDF files. These documents list the most current NSRL/MADL values.
