Recology Hay RoadWaste Water Treatment Sludges
Waste Water Treatment Sludges are accepted dry or wet. Wet material is stored during the winter months (October through April) in the site's specially designed Class II waste pile. Subsequently, the material is removed from the waste pile, dried and blended with on-site soils, and used as an operations layer in landfill liner construction.

Asbestos and Other Waste
Friable and Non-Friable Asbestos materials are placed in the site's designated inert monocell. Special wastes, including contaminated soils, are also accepted and utilized as refuse cover material. Special wastes, including waste water treatment sludge, contaminated soils or other designated wastes, are subject to analytical review and must be classified non-hazardous under the state's hazardous waste criteria.
