Non-hazardous sludge can be disposed of through any method though you must provide documented evidence that your facility’s sludge is not hazardous.

How is your sludge disposed of?

• Hazardous Waste Treatment
• Incinerated controlled conditions
• Landfilled
• Open burning
• Fuel Blended
• Composted
• Fertilizer (applied to land)

Suggested Upload: a) Sludge analysis or test results from last 12 months (if non-hazardous is selected); b) permits or manifests for proper disposal or land application.

• An inventory of the amounts and types (non-hazardous and hazardous) sludge generated
• Lab analyses showing the non-hazardous and hazardous (if applicable) components for the various types of sludge
• Documentation showing methods for disposing each type of sludge
• For off-site disposal, invoices or delivery records confirming that the types of disposal selected here reflect what’s being used in practice
• If disposal is done via landfilling, open burning, compost, fuel blended, or as fertilizer applied to land, the sludge must be analyzed and documented as non-hazardous and suitable for the particular disposal method.
• Permits, if applicable for a particular disposal method

• Interview discussions
• Is there an in-depth and up-to-date knowledge of the sludge components? How is sludge regularly analyzed to ensure it is properly disposed of?
• Is management and responsible employees aware of proper disposal methods for each type of sludge
• Inspection – things to physically look for
• Site or area and process for disposing of sludge if it is one on-site
• Please take photographs
