Operation Scarlift (also known as Project 500 or The Bond Issue Program[1]) was a program carried out by the Pennsylvania government in the 1960s and 1970s.[2] Its mission was to repair environmental damage caused by abandoned mine lands, acid mine drainage, and other issues associated with historic mining. The operation began around the time that the Land and Water Conservation and Reclamation Act was passed and became inactive in the 1970s due to a lack of funding. During the operation, a total of $141,000,000 was spent on a variety of tasks, including remedying pollution in hundreds of streams, extinguishing dozens of mine fires, and constructing acid mine drainage treatment plants. Numerous reports on mining-impacted streams were produced during the operation, many of which continue to be used for assessing watersheds.
