Case 09-E-____; Case 09-G-____ (NYSEG)DIRECT TESTIMONY OF THE CAPITAL EXPENDITURES,RELIABILITY, AND OPERATIONS PANEL12345678910111213141516171819202122Q. Will you please provide a short summary of the incremental O&M work related tothe dredging of Rainbow Falls?A. Yes. The Rainbow Falls project is located on the Ausable River in Keeseville,New York. A dive inspection of the canal intake and low level discharge gate inthe concrete dam shows a heavy buildup of river silt on the upstream side of theintake and dam. This buildup is beginning to impede the flow of water into theintake/power canal and discharge gate. The silt needs to be removed to maximizeoutput of the generating units and for reliable operation of the discharge gate. Tocomply with the project's FERC license and environmental concerns, the silt mustbe removed as it cannot be flushed downstream. The initial dredging will becompleted in August 2011 when the plant is out of service for the construction ofthe Rainbow Falls Fish Bypass and Trash Rack Project, at an estimated cost of$150,000. Silt removal will need to be repeated every 3-5 years at an estimatedcost of $50,000.Q. What is the incremental O&M work related to the clearing of debris in the roadculverts at Wayne Gates?A. A dive inspection to determine the condition of the concrete culverts found themto be nearly blocked with natural debris (stone, logs, branches and silt). During aheavy storm, the partial blockage could cause water to backup, overtop anddamage a newly constructed earthen berm. The initial cleaning of debris will bedone in 2010 at an estimated cost of $225,000. It will need to be repeated every3-5 years at an estimated cost of $25,000.29
