SDM
567 proceedings under this prefix, in the Board's own numbering. One row per number the Board opened directly; a sub-docket is listed on its own series’ sheet, which is what a row links to. A proceeding holding nothing is listed all the same — the Board opened it, and the number is the answer where the documents predate this record (coverage).
