The work to be done is the installation of a sump in Little Teapot Creek from which water for the cooling loop at the North Waterflood Facility can be withdrawn. The work will consist of burying a section of 8 foot diameter galvanized steel culvert in the creek to produce a sump for the suction of a pump. The culvert will be set vertically to the bed rock or to a maximum depth of 8 feet, which ever is less. The permit for withdrawal of the water has already been received.
