Please note that as of January 2025, changes are still being made to exactly where the open source project will be shared, documented, and available for contributions (such as submitting Issues or Pull Requests on GitHub). In the short term, it is important to note that the "EJAM" package is shared at the "EJAM-open" repository even though the documentation website still refers to and tries to link to a different, nonpublic repository called "EJAM" which may cause some confusion. An interim solution is to clone and work with the EJAM-open repository and just avoid using any weblinks pointing to USEPA/EJAM rather than USEPA/EJAM-open. The open source EJAM package was initially made available via the EJAM-open repository, but the EJAM package documentation was initially published from a non-public development repository, so that documentation's links to source code did not work (because they required access to a separate, non-public repository).
