How many tons of concrete will be poured on the launch shaft site pads?June 12, 2020
Do you plan to rehabilitate the levees at launch sites and to what level in order to protect construction operations?June 12, 2020
Excavated soils, with or without peat, would need to be managed on-site to prevent particulate matter, including dust and peat material, from leaving the construction site boundary. At the tunnel shaft locations, the excavated material (approximately 600 cubic yards from the vertical shaft excavation) would be placed in areas to be managed to allow for testing prior to disposal or reuse. This will be analyzed in the environmental document, and any mitigation will be provided there.
