HCFC-22 is compliant with the prerequisite. However, as of January 1, 2010 manufacturers were no longer allowed to produce equipment containing HCFC-22. That doesn't mean they can't (and don't) still manufacture equipment that operates on R-22, but is uncharged when it's delivered to the site.
Are you wondering from a new equipment purchase or an existing system?
This EPA site has some good timeline information: http://www.epa.gov/ozone/title6/phaseout/22phaseout.html

Thank you for the rapid response. We are constructing a new core and shell on healthcare campus that is served by an existing chiller plant. USGBC district energy guidelines stipulate that all chillers must meet EAp3 requirements. 2 chillers currently use 134a, 2 use R-22 and one uses HCFC 123. It is my understanding that HCFC 123 is not compliant and will require a phase out plan - is this corrrect? Also, can we simply demonstrate that the compliant chillers serve our building exclusively or do we need to ensure that the entire plant meets EAp3 requirements? Thank you for you input.

EAp3 only excludes the use of CFC-based refrigerants. R-22 (HCFC), R-123 (HCFC) and R-134a (HFC) are all compliant with the prerequisite, because they are all non-CFC based refrigerants. Therefore you don’t need to worry about a phase-out plan.
Where you may run into an issue is if you’re also pursuing EAc4 – Enhanced Refrigerant Management. R-22 has the highest Global Warming Potential (GWP) and Ozone Depleting Potential (ODP) of those 3 refrigerants and you’re total impact per ton may exceed the allowable limit.
I hope that helps.
