Attention: the SPCS2022 Policy, Procedures, and associated forms are now available to the public at There is also a link to an FTP folder with examples of completed forms (and associated files).

I am sure that we will soon make a general announcement.Note that the quick links on the left side of the SPCS page set have been reorganized, and some have changed:* Final SPCS2022 Zones ( This is a new page that will show the final zone parameters are they are defined.
