Mike, the former Sta B property was immediately west of the old Uniroyal plant property [[hence, MichCon's involvement in the site cleanup plan). The former Sta A was the property near the Ambassador Bridge. It was one of the first sites in Detroit for manufacturing gas. The Noble St. property was used for offices, transportation and service facilities. There were no gas holders there.

There's also a book on the history of MichCon entitled Keepers of the Flame, The People of MichCon.
I'm an old gas guy.
