Mon Valley Works: FAQ

- Who owns Mon Valley Works?

- Is this the same as Mon Valley Works LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — United States Steel-Mon Valley here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Mon Valley Works LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
