Prop 65California’s Office of Environmental Health Hazard Assessment (OEHHA) on April 5 issued a second round of proposed amendments to its Prop 65 regulation.

These amendments reverse several of the proposals introduced on December 13 of last year. The modifications of note to the rule are as follows:

  • The label size and package size limitations introduced in December of 2021 related to the use of the short-form warning were removed.
  • The new short-form font type size requirements were removed. The existing minimum 6-point type size font for short-form warnings remains unchanged.
  • The implementation date for the final rule is now two years instead of one. 
  • The modification reverses the restrictions on a business’s ability to warn on a catalog or website 

OEHHA announced a 15-day window to comment on the second round of proposed amendments, which ended on April 20, 2022.

OEHHA will resume their rulemaking process and prepare to release a final regulatory determination or issue a third round of modifications to the existing rule. AEM will continue to monitor these developments as more information becomes available.
