4-6 weeks after the Roster Board meets*. The Roster board meets 4-6 times a year, so it depends when you submitted it. The next meeting is TBD, the last one was 1-31 I think. When did you submit it?
* Depends on the COMAR schedule: They submit the approved roster to COMAR, then there is a 30 day comment period before its official. COMAR takes notices 1-2 weeks before publication.
