Are property owners obligated to cleanup the properties if an environmental impact is discovered?

The project does not impose any clean up requirements, but does provide valuable information and expertise to make informed decisions with regard to environmental matters. The only exception might be that a property owner may be obligated to report impacts originating from their property if it is found to be affecting neighboring/adjacent properties or public health. Cleanup or mitigation of contamination (e.g., a restrictive covenant) is dependent on many criteria including land use goals and whether the impact is confined to the property.
