Oil refinery waste reclassified as non-hazardous in Texas

The EPA is proposing to remove petroleum refinery sludge from the federal hazardous waste list for one Texas refinery, making it legal to dispose of in a regular landfill instead of a specialized hazardous waste facility. This means WRB Refining can treat up to 700 cubic yards per year of this sludge as ordinary trash rather than as toxic material requiring special handling.

Delisting decisions set a precedent for how similar wastes are classified across the industry — if approved, other refineries may petition to do the same, shifting disposal costs downward and potentially changing which landfills can legally accept this material.
