No mention of real specifics in Sixth World Alamanac, just that lots of Scotland's still cordoned off as miserable toxic wastelands. The Scottish Fringe Toxic Zone is the most specific it gets, with the freaky oil spill that's inching up onto land, instead of following currents and winds.
SoE mentions rugged highlands and remote coastal isles, so that their Wild Zones are fringing in one Habitable Zones. The Scotsprawl is the big urban center, and out in the moors and highlands Clan laws still rule (with feuds, etc, the order of the day).
Nothing, at any rate, that seems like it would interfere with the game you've got planned.
