Before the cleanup of a nuclear waste dump in Parks Township, Armstrong County, continues, the Army Corps of Engineers will have to justify the escalating costs of the project.
Officials told residents at a meeting this week that a review is required under the federal Superfund law when the cost of cleanup exceeds the original cost estimate by 50 percent.
The excavation of the site in Parks Township was estimated to cost around $45 million in 2007. Because of the complexity of materials found on that site and the safety precautions required of a contractor, the cost has now ballooned to $500 million. Another law mandates cleanup of the site and officials say the only way to do that is to move the nuclear waste.
If the clean-up does go under review, more public hearings could be held. Similar hearings were held when the original excavation plan was adopted in 2007.
