Biosolids Flowchart Sewage Wastewater Treatment Plant Biosolids Biosolids and Other Land Applied Disposal Beneficial Use Sludge Wastes in Idaho Surface Disposal Land Application May 16-17, 2012 http: / / biosolids.agsci.colostate.edu/ Biosolids Flowchart What are the differences? Sewage Land Application Wastewater Treatment Plant Beneficial use Biosolids Storage Disposal Beneficial Use Placed and remain on land < 2 years Surface Disposal Surface Disposal Monofills Waste Piles Final disposal Surface Dedicated Impoundment disposal sites Biosolids Flowchart Surface Disposal Sewage General requirements Wastewater Treatment Plant Pollutant limits Biosolids Management practices Disposal Beneficial Use Operational standards for pathogen and VAR Surface Disposal Monitoring and record keeping requirements Reporting Requirements Incineration Landfilling 1
Landfilling Landfill Operators Regulated by Part 258 of Landfill Rule Ask for documentation for Pass the paint-filter liquids test Hazardous waste characterization (dewatering biosolids to about 20 percent solids or more Paint filter test results will generally meet this goal) Cannot contain > 50 ppb of polychlorinated Procedures in operation plan for how they will biphenyls (PCBs) (40 CFR Part 761) manage biosolids Must not meet the definition of hazardous wastes Waste Acceptance Criteria Biosolids Flowchart Biosolids Incineration Sewage Involves the high temperature burning of biosolids in an enclosed devise Wastewater Treatment Plant Uses an auxiliary fuel supply Biosolids Gas, oil, wood chips, coal Disposal Beneficial Use The resultant ash is significantly lower in volume Surface Disposal than the feedstock (biosolids) Land filling Incineration Biosolids Incineration Biosolids Incineration Concentrates the trace metals Part 503 Incineration Requirements include: Ash Pollutant limits Non hazardous ash is not covered by Part 503 rule Limits for total hydrocarbons when it is used or disposed General requirements and management practices Ash is disposed according to solids waste disposal Monitoring, record keeping and reporting regulations in 40 CFR Part 258 requirements If ash is land applied then 40 CFR Part 257 applies 2
The Septic Tank connection… Other Sludge Wastes Septage and Pumpable wastes Biosolids Septage is classified according to the Domestic Septage environment in which it is generated. Domestic septage Industrial and Commercial Pumpable Wastes Industrial or commercial pumpable wastes Domestic Septage Mixed with Industrial or This is non-domestic waste Commercial Pumpable Wastes Domestic septage mixed with non-domestic pumpable wastes Biosolids Flowchart Domestic septage Residence Domestic septage is the liquid or solid removed Sewage from a septic tank, cesspool, portable toilet, type Septic Tank lll marine sanitation device, or a similar system Effluent that receives only domestic septage Domestic Wastewater Treatment Plant Septage Household Residence Sludge Non-commercial Non-industrial Septic Tank Biosolids Beneficial Use Disposal Domestic Septage Domestic Septage Domestic Septage Land Applied Domestic septage mixed with any sewage sludge Domestic septage land applied is considered sewage sludge.
