Level adjustments that would take a monster PC into Epic progression

[IcyCool]

I know that in the MM it states that level adjustments are only given for those monsters where the HD + LA would not take the PC into Epic progression. But are there rules for LA on monsters without it? Like some of the more potent celestials and infernals? If so, where are they?

Failing that, how would you go about determining the LA?

I'd use the guidelines from Savage Species, if you have access to it.
