Moundsville WV explosion: Liquids or Gas line?

Mainstream media has mostly reported the Moundsville WV explosion and fire at a (natural) gas pipeline leading between two Williams Partners owned facilities (Moundville WV and Oak Grove/Cameron WV)/

However according to NPMS, this is most likely a liquids pipeline (condensate, a/k/a/, NGLs: Butane, Pentane, Propane).

• http://www.theintelligencer.net/page/content.detail/id/598301/Pipeline-Rupture-at-Oak-Grove-Si---.html "Natural gas pipeline" "the line that ruptured in Marshall County was transporting natural gas drawn from Marcellus Shale well sites to the Williams Energy Oak Grove processing plant near Cameron."

  "Gas line" changed to "Pipeline". First responders thought it was at a well pad at Oak Grove.  Commentator at the end nearly correctly identifies it as a "liquids gas pipeline".

The exactly location is difficult to ascertain. I have read all news reports and examined photos and have determined the most likely location is a section of co-located liquids AND gas pipeline just northeast of the Williams Oak Grove facility.

It seems to be near a facility, however it is unclear if this is the Oak Grove facility near Cameron or not. Some reports say the fire/explosion was there, some say it was not there. Some reported first responders were confused about the exact location.
