THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS: SECTION 1. Section 41511.5 is added to the Health and Safety Code, to read: 41511.5. The state board shall conduct a study of ambient air concentrations of manganese in the state to determine if there are areas in the state that have unhealthy concentrations of manganese. No later than January 1, 2010, the state board shall submit a report to the Legislature that describes the conclusions of this study and provides recommendations for reducing manganese exposures as needed.
