On June 30, 2011 the FAA will be changing the FAA NOTAM system to be more compliant with ICAO standards.
It appears that the biggest change is going to be a relocation of NOTAMS referencing ODPs, STARs and SIDs from the section containing D (distant) NOTAMS to the section containing FDC (Flight Data Center) NOTAMS.
There will also be some wording changes which will attempt to make the NOTAMS easier to interpret.
