I don't believe this is designated as a forest service road anymore. The government permit dataset shows this as a permit road under Hillcore Lakeside Pacific Forest Products Ltd with the road section id (name) of "T1".

It may be that the "Talc Creek Forest Service Road" name comes from the new backroadstatus.com website. That operator of that website often makes up names for roads or uses very out of date maps (Backroad Map books) in coming up with the names of roads.
