Michael H. Pratt, chief plant operator at the Canastota Waste Water Treatment Plant released the February report to Mayor Todd Rouse and the village Board of Trustees.
Pratt's report indicated that during the month of January the plant was over its maximum flow for the month. He said it was an excursion to the SPDES permit because the plant has only a 30-day average of 1.73 million gallons a day.
Pratt said he sent a letter of non-compliance to the state Department of Environmental Conservation.
"This is very confusing," Pratt stated, "because our wet weather operating plan states 'maximum flow to the WWTP,' which we have done. This is an issue that will have to be brought up with the DEC in the future."
"It is important to remember, this is not a violation of the permit, nor was there any affect on the secondary effluent quality," Pratt added. "Percentage pollutant removal was nearly 99 percent. Our limit is 85 percent."
A drive unit on the final clarifiers had to be replaced, Pratt said. Pratt explained that the drives are used to push settled solids to the return pumps located at the influent end of the finals.
"We purchased a new drive during the summer of 2006 and easily installed it," Pratt said. "Due to design of the finals, one drive unit does work in two of the final settling tanks, so when a drive unit breaks, the plant is reduced to 50 percent of its capacity. We still have to purchase a new drive, which is $600 less than doing a rebuild on the old one, due to parts, availability and age."
Pratt said at some point the plant should look at putting a drive on each of the finals, which is easily accomplished.
"The village of Canastota waste water facility is currently producing a high quality effluent in full compliance with its SPDES permit," Pratt said.
