Scrap influx on the NS?

Here in East Tennessee i’ve been noticing trains have been getting a lot of scrap gondola’s coming westbound from John Seveir Yard, anyone know what the origin of this scrap is? it’s mostly NS and Omnisource gondolas. And when i say a lot, I mean at least 25% of this one train was scrap filled gondolas.

Also speaking of Omnisource. Did they get new gondola’s? Cause I saw a few fresh looking ones recently. Were they new acquisitions or repaints?

Two possible contributing factors?

China puts up a green wall to US trash

East Asian importers buy Japanese steel scrap as US offer prices rise

My understanding is that a lot of the scrap may come from the Omnisource plant in Johnson City TN served by NS. Also, there is another NS served Omnisource plant between Bulls Gap and Rogersville TN.
