Bonneville Power Administration proposes to upgrade the secondary containment system at Hatwai Substation for the protection of environmental resources from stormwater runoff and protection of environmental resources. All work will be conducted within the existing facilities, within the existing fill prism of the substation. Two 8 foot x 16 foot (interior volume) vaults will be installed within the substation, along with associated piping to connect the area of protection to the vaults. This will ensure that any potential leaks would be captured for proper management.
