Documentation is available for the previous OBODM version 1.3. This version was developed by Jay Borklund, James Bowers, Gregory Dodd and John White in conjunction with H.E. Cramer Company. Version 1.3 was published and disseminated Feb. 1998. The current version is based on OBODM 1.3.
The OBODM 1.3 user manual has three volumes, including
- Volume 1. Users Instructions
- Volume 2. Technical Description
- Volume 3. Program Maintenance
All three volumes are in PDF format and can be access through this menu. While the technical information is the same for version 1.3 and 2.0, the user interface and maintenance is different. This information is only provided as a service for those migrating from version 1.3 to 2.0.
There is also a link to the EPA web site that freely distributes the OBODM version 1.3 program code. This link may change over time, but currently the EPA still provides free download of OBODM version 1.3.
