The dates for final completion was originally set for December 31, 2020 but was extended for 10 years to December 31, 2030. Why? In reference to the deadline, why ten years instead of 3 to 4 years for example?

The extension to the cleanup deadline was agreed by Sunoco and the PADEP in the CO&A amendment in 2020 because of bankruptcy of PES and impending acquisition of the property by Hilco, which included a substantial and material change in the use of the site. Evergreen must coordinate its Act 2 timeline with Hilco’s redevelopment timeline, which is expected to be approximately 10 years. The planned future use of the site (including, for example, the locations and construction details of buildings) must be known before generating Cleanup Plans.
