Greenfield status
From Wikipedia, the free encyclopedia
Green Field status is a term used to describe an end point wherein a parcel of land that had been in industrial use is, in principle, restored to the conditions existing before the construction of the plant. It is synonymous to a status of unrestricted re-use; the older term.
All power plants, coal, gas and nuclear, have a finite life beyond which it is no longer economical to operate them. At this point they must be decommissioned; that is they must be dismantled and their components disposed of ether by sale or scrapping. In some cases the buildings that housed the plant may be put to other uses however in many cases contamination is unacceptable and they too must be demolished. The land on which the plant sat may too have been polluted with high levels of toxins, and in this case other remedial measures like removal and replacement of the top soil, or clay capping may have to be done to render the site non-hazardous.
It is becoming standard practice in many jurisdictions to mandate a return to Green Field status at the end of plant service as a condition of the initial site license, and potential licensees must demonstrate that steps will be taken to assure the availability of funds via the posting of a Reclamation Bond for that task before a site-license will be issued. While this concept has mainly applied to the power generating industry, the term is coming into wider use in other areas of industrial decommissioning.
