Under the Voluntary Cleanup Program, we provide written opinions on planned and completed independent cleanup actions, including:
- Remedial investigations of contaminated sites
- Feasibility studies of cleanup alternatives
- Property or site cleanups
What is the difference between a property and site cleanup?
Property cleanups include some, but not all, properties located within a contaminated site. Site cleanups include all properties within a contaminated site.
For example, a leaking underground storage tank could cause groundwater contamination to extend to a neighboring property. By law, the cleanup site (also called a "facility") includes everything contaminated by the leaking tank (or any source of contamination), whether it is on or off the tank owner’s property.
