In that case, it depends on the wording of this guideline here:

If this is updated for the 2010 season in such a way that leaves it saying 09 season instead of 08, or the previous seasons do not apply to the bolded part of the quote, it's probably D2.
There's also a handy little ranking checker on the APPA if you have access to login info. Just go to the profile page and click "classification" - there will be a list of leagues to check your rank in.
