Document Type
NOE - Notice of Exemption
Document Description
The repair site is approx. 400 feet long, with each panel measuring roughly 12.5 feet by 12.5 feet. The contractor will drill through the aqueduct secondary access road and embankment to a depth of approx. 30 feet. Grout will be pumped into the bottom of the drilled hole with the objective of filling voids in the embankment or foundation. Minor repairs to the concrete panels will be done by divers who will apply epoxy to small cracks. Larger cracks will be repaired by divers who will drill holes into and through the concrete lining near and around the damaged area. Grout will then be injected into the drilled holes, filling any voids behind the lining. After the voids are filled, the drill holes will be sealed with epoxy.
