Initiation of final restoration and grading following spring runoff and flooding. View looking south at the western Site boundary where seed and straw matting were placed to stabilize soils during the seasonal suspension of work. Restoration work will resume in Spring 2013. View looking north at gravel and boulders placed along the eastern Site limits to allow for access to the ATV and snowmobile trail. View looking northwest at boulders placed along the Site boundaries prior to suspension of work. Restoration activities will resume in Spring 2013 View looking northwest at the application of concrete sealant and paint to cover the exposed concrete pads that once served as the foundation for the gasometers at the plant. Power washing gasometer base Extent of contamination trenching Extent of contamination trenching along the eastern edge of the site Overview of the Site. Removing impacted concrete from the gasometer foundation. Eastern edge of former building foundation. Piping uncovered during the excavation. Excavating around the western gasometer foundation, as viewed from the north side of the Site. Exposed edge of the gasometer foundation on the west side of the Site. A buried concrete structure located between the former plant and the western gasometer. During removal of the structure it was found to be filled with black contaminated soil. No subsurface pipes or drainage features were observed emanating from the structure. View looking east/southeast at removal operations. The contaminated soil stockpile and temporary haul road were relocated to the southern limits of the property to allow for the excavation of the southern half of the Site. View looking west at the excavated foundation of the western gasometer. The concrete foundation of the gasometer is greater than 4 feet thick. View looking south/soutwest at removal operations. The yellow excavator is excavating contaminated soil, the front end loader transfers the soil to the stockpile, and the red excavator loads haul trucks for transport to the disposal facility.
