AWARD BID - CHLORINE AND SULFUR DIOXIDE - WASTEWATER TREATMENT PLANT Mr. Robert Toppel, Environmental Services, advised the Board that on March 23, 1998, bids were received and opened for the above referred to items. After reviewing those bids, Mr. Toppel recommends that the Board award the contract to Alexander Chemical Corporation, 2525 Cabot Drive, Lisle, Illinois, in the amount of $298.00 per ton for liquid chlorine, and $410.00 per ton for liquid sulfur dioxide. Mr. Toppel stated that the Alexander Chemical Company was the low bidder for the chlorine and the second lowest bidder for the sulfur ,dioxide. PB&S Chemical was the low bidder for the sulfur dioxide and the third lowest bidder for the chlorine. The difference in the bids between Alexander and PB&S for the sulfur dioxide is $10.00 per one ton container. The number of sulfur dioxide containers ordered and used during a year is 28 or an average of four per month during our seven month chlorination/dechlorination season. Two full containers are kept for the other five months. During start up, four containers are ordered. The next order will be for an additional four containers when there are only two full ones remaining. This makes a total of six sulfur dioxide containers on site at all times. The Alexander Company does not physically charge for deposits on their containers. They only track them when delivered and returned. PB&S does require deposits on their containers, so there is a charge when they are delivered and a credit when empties are returned. The cost of the deposit on a sulfur dioxide container is $1,200.00, and we will have at least $7,200.00 tied up during the seven month chlorination/dechlorination season, and an additional $2,400.00 during the five other months. The cost savings by accepting the bid for sulfur dioxide from PB&S instead of Alexander is $280.00 per year. However, the lost interest from the deposit charges with PB&S is $260.00 per year. This produces only a $20.00 savings. It is believed that the cost savings of $20.00 per year is not enough to balance the additional non -monetary costs that would be included if the bid is divided.
