Step 5: Solids Disposal Overview (B-FSM-165)

There are four main groups or categories of disposal locations. These will be detailed in a subsequent post.

  • Landfill disposal
  • Overboard discharge
  • Slurry fracture injection (SFI)
  • Unique methods

Environmental regulations concerning specific contaminants is primary factor in disposal route

  • Oil/hydrocarbons: <1 wt.% oil-on-dry-solids for overboard discharge, but hydrocarbon level is often not critical for most landfill or SFI
  • Heavy metals: specific requirements for overboard discharge and landfill but not a factor in SFI
  • NORM: specific requirements for overboard discharge and landfill but not a factor in SFI

Determine environmental regulations for disposal as first step in design of solids handling system
