CAMEO Data Manager Software

CAMEO Data Manager is a database application where you can keep track of information (such as chemical inventories and contact information for facilities) to assist in emergency response and planning in your local community.  It is especially useful for managing data required under the Emergency Planning and Community Right-to-Know Act (EPCRA). 

You can enter information into the CAMEO Data Manager database manually and/or by importing a Tier2 Submit™ file (if the facilities and/or planners in your state use that program to complete Tier II forms under EPCRA).

CAMEO Data Manager is part of the CAMEO® software suite, which is used widely to plan for and respond to chemical emergencies. CAMEO Data Manager replaces CAMEOfm, and offers new functionality and features. Files created in CAMEOfm and Tier2 Submit can be imported into CAMEO Data Manager.
