This list for Prop 65 on hazardous chemicals priorities in harbors was released by the California Office of Environmental Health Hazard Assessment (OEHHA).

The Office of Environmental Health Hazard Assessment (OEHHA) has developed the priority list below for the development of safe harbor levels for chemicals listed under Proposition 65 for which levels have not been adopted in regulation (in Title 27, California Code of Regulation, sections 25705, 25709, and 25805).

OEHHA assigns priority levels based on the availability and quality of scientific data for dose-response assessments, potential for exposure, resources available to perform the assessment, need expressed by interested parties, and input from the public and the Attorney General’s office.  Also, priority is generally given to chemicals newly added to the Proposition 65 list.

Priorities change as assessments are completed or the basis for the priority changes.  Any interested party may recommend changes in priorities to OEHHA, preferably with supporting rationale for the change.
