Are you burning nonh azardous solid waste?

摘要

The recent designation of biosolids incinerated at publicly owned treatment works (POTWs) as "non-hazardous solid waste" by the U.S. Environmental Protection Agency (EPA) will have a considerable impact on facilities with sewage sludge incinerators (SSIs). Under the new definition, the limits for incinerator emissions will be established using maximum achievable control technology (MACT) provisions under the Clean Air Act (CAA) Sec. 129 waste incineration regulations. The application of Sec. 129 regulations to SSIs requires POTWs to meet more-stringent emission limits. POTWs that incinerate wastewater solids face a decision about whether to continue operating their SSIs - and potentially upgrade emission control equipment - or to replace existing SSIs with new ones that have advanced emissions controls to meet emissions deadlines and avoid incineration shutdown. If facilities instead choose to discontinue incineration, they must soon complete plans to implement other process alternatives, such as landfilling of dewatered cake or digestion and drying.
