The North Little Rock Electric Department is proposing to use Department of Energy American Recovery and Reinvestment Act funding to purchase and install an intake maintenance device and its associated equipment at their hydroelectric generation facility located at the Murray Lock and Dam #7, on the McClellan-Kerr Arkansas River Navigation System, in North Little Rock, Arkansas. They are also proposing to use funding to purchase, use and maintain a Morbark 1300B tub wood grinder. The intake maintenance devise would automatically keep the intake channel clear of the volume of debris that comes downstream into the facility. The proposed wood grinder would receive the tree limbs, tree trunks, and other organic debris removed by the intake maintenance device and would chip it up into mulch for the community's use. The purpose of the system would be to remove debris from the river to allow the hydroelectric facility to operate at higher efficiencies.
