I would recommend you call your PEBLO and ask to confirm if the PEB has submitted your signed findings to MMSR4. When I called MMSR4 they said that when they receive packages it normally takes 48hrs for a new EAS to generate. If the PEB or your PEBLO are able to confirm that your case was forwarded to MMSR4 and you need to get in contact with MMSR4 here is the POC:
1(703) 784-9308 or
[email protected] (they are currently teleworking, so I would double tap. There seems to be a Marine available to call during the morning times). It's quantico so we are Eastern Standard time if that helps. I am waiting for my PEBLO to get back to me to tell me if the PEB did their job or not.
