DENVER, Colo., U.S. 2/15/12 (PennWell) — The Bureau of Reclamation seeks information from firms capable of providing environmentally compatible control of invasive quagga and zebra mussels on the Lower Colorado River at 2,078-MW Hoover Dam in Arizona and Nevada, 255-MW Davis Dam in Arizona, and 120-MW Parker Dam in California. Responses are due Feb. 23.
The bureau’s Boulder City, Nev., office issued a sources sought announcement to determine if there are firms capable of providing control of the foreign species, which are spreading through U.S. waterways. It will use responses to determine its overall procurement strategy.
Reclamation took information from contractors in 2010, seeking firms capable of performing studies related to quagga and zebra mussels.
The foreign mussels were first identified in North America in the Great Lakes, and have spread from there. When present in a cooling water source, they attach to structures such as piping, valves, and filters where they block the flow of water, adversely affecting hydropower equipment to the point they must be taken off line for repairs.
The first quagga mussel infestation was identified on the Colorado River in 2007. Although no zebra mussels have been found on the Colorado, Reclamation desires a technology that can address both species in the event a zebra mussel infestation occurs.
Reclamation now seeks information from firms capable of deploying an anti-mussel technology that does not have a significant negative effect on downstream water quality, the environment, or people.
Responses are due by 4 p.m. Pacific time, Feb. 23, by mail or e-mail to the address below.
