If the project generates excess soil that cannot be managed on site, there are a few basic options that depend on what is in the soil:
Non-hazardous soil:
If the material is clean, it may be reused at another campus project location, brokered to a non-University off-site construction site, or disposed of at a municipal (sanitary) landfill where it is usually used as landfill cover.
Contaminated soil:
If soil contains contamination such as asbestos, lead paint or other metals, PCBs or petroleum at concentrations that exceeds regulatory limits, it must be disposed of at an appropriate disposal facility, usually a hazardous waste landfill.
