Welcome to the California Environmental Reporting System (CERS)
CERS Central will be upgraded to the latest California State Template Version 5, soon. Click here (PDF, 1 pp, 496 KB) for an example of the v5 template, which provides a new look and feel to CERS Central’s icons and navigation menu. Changes to CERS Central will be rolling out in the next few weeks (July 2018).
Effective December 28, 2017, CalEPA will be replacing the existing five (5) federal hazard categories available in CERS used for the completion of chemical inventories as part of the annual hazardous materials business plan submittal with twenty-four (24) new federal hazard categories adopted by the United States Environmental Protection Agency (U.S. EPA) as a result of changes to the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard (HCS).

EPA developed a cross-walk in coordination with the Occupational Safety and Health Administration (OSHA) to assist facilities in comparing OSHA’s original and new physical and health hazards adopted from the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). If you have difficulty determining the appropriate new hazard category from a SDS, or an updated SDS is not available, this document may help you determine the best choice of new category to use in updating your inventory.
