Once a code change request becomes a minor or CBHCC approved task, it transitions to a proposed change that follows the path outlined in the code development process.
This proposed change tracking database can be used by code change request proponents to follow the progress of proposed changes for a task linked to their code change request. Information in the database can be accessed using the filter option or toggle arrows to sort by:
- ID number (the number assigned when a code development committee has started its work on the issue and created a proposed change form for potential publication),
- title,
- description,
- code reference,
- status (the progress of the proposed change through the system), and
- code change request (the corresponding code change request number assigned when it was originally submitted by a proponent, see the code change request tracking database).
Please direct any questions related to code change requests to CBHCC code change request.
