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

Next week I will show examples of solids disposal methods.
