What year was the landfill closed? What if any regulations would the Landfill have to have complied with during the closure process?

During the 1960s, there were minimal environmental regulations regarding landfills and their closure protocol. Historic aerial photographs do not depict organized landfilling via waste disposal on the land after 1963, indicating that most of the activities associated with the Norwood Landfill Site occurred prior to regulations. Additionally, there are no identified records that indicate the land was used for waste disposal after this time.  It is possible that unauthorized dumping of waste materials could have occurred in the area over the many years since the active landfilling operation ceased.
