BACKGROUND:
The purpose of this legislation is to authorize the Director of Public Utilities to increase the amount of the contract for Refractory and Thermal Systems Maintenance Services, FEM Project No. 1301.2, for the Division of Sewerage and Drainage. The Director of Public Utilities opened formal bids on June 20, 2007 and one bid was received.

These incinerators normally process an average of 240 wet tons of sludge per day in order for the plant to maintain its sludge inventory at an acceptable level and operate at peak efficiency. In February 2008 the plant removed No. 3 incinerator from service because a large piece of refractory had fallen down into the incinerator. The Adrian L. Wallick Co., holder of the Refractory and Thermal Systems Services contract, was called to perform an incinerator inspection and complete any necessary repairs in accordance with the contract. The Adrian L. Wallick Company inspected the incinerator and exhaust ductwork where the refractory had failed. That inspection revealed that two hearths within the incinerator required replacement and identified serious problems in the incinerators' exhaust ductwork relating to the deterioration of the outer metal shell of the ductwork. Operating the incinerators without making the necessary repairs could result in major damage to the incinerators and associated equipment. Failure to make the necessa...
