The Staged Electronic Data Deliverable (SEDD) Generator Tool creates Extensible Markup Language (XML) data deliverables that can be read by any user on any computer platform. Currently, U.S. Environmental Protection Agency, (USEPA) has deployed two versions of the SEDD Generator Tool, the Java Web Start (JWS) Tool, and the Stand-Alone Tool. To invoke the JWS Tool, or to download the Stand-Alone Tool, you must use Microsoft® Internet Explorer (IE) Version 8 with Java™ Support enabled.

The latest release of all versions of the SEDD Generator Tool now allows laboratories to generate SEDD files containing all DTD tags.

The USEPA/Analytical Services Branch (ASB) allows any laboratory the use of this tool. Please contact Michael S. Johnson ( if you need an account for the SEDD Web-based tool.
