Water: Discharges are estimated using the approach applied to air emissions but apply factors for carbon bed adsorption efficiencies in placeof scrubber collection efficiencies. Monitoring data required by the facility's NPDES permit (issued mid-2003) will be incorporated in future reports. Waste: The reported values includethe APFO content in solid wastes sent to off-site commercial treatment facilitiesforeither incineration or biotreatment. Sludges from the biotreatment facility are deposited in a commercial landfill. Incinerated materials include in-process wastes and off-quality materials that have been characterized to determine typical PFOA levels. Activated carbon from the water treatment units is also incinerated. PFOA levels treated in this manner are estimated using the approach applied to water discharges.
