INVOKE EMERGENCY POWERS OF BOARD AND AWARD CONTRACT - REPLACEMENT OF A TERTIARY CLARIFIER MAIN DRIVE BEARING - WASTEWATER TREATMENT PLANT In a letter to the Board, Mr. Karl R. Kopec, Manger of Operations, Division of Environmental Services, requested that the Board declare the replacement of a tertiary clarifier main drive bearing to be an emergency. This declaration would allow the Bureau to contract for the repair work without soliciting quotes. Mr. Kopec noted that this bearing failure has reduced the tertiary treatment capacity of the Wastewater Treatment Plant by one-half. Tertiary treatment is employed to remove phosphorus as mandated by the Plant's NPDES Permit. Time is of the essence in effecting this repair to restore full treatment capacity. He noted that the drive bearing is five feet (51) in diameter and supports the sludge collector mechanism in a 200-foot diameter clarifier tank. Based on past bearing replacements, this work will cost around $15,000.00. The Bureau would employ the contractor that replaced the main drive bearing in the other clarifier to save time and to reduce the potential for delays or hang-ups in the repair work. In response to questions from the news media, Mr. Kopec reiterated that the work entails the replacement of a main bearing in the center of the clarifer. He indicated that the contractor who did work previously at the plant is Industrial Installations, Inc., of Mishawaka, Indiana, who is familiar with this type of work and can get in and out quickly. Mr. Kopec also advised that the plant is in compliance with their permit at this time treating seventy per cent (70%) of the phosphorus. Mrs. Mueller made a motion that the Board declare that an emergency exists that requires immediate replacement of this bearing and award the contract to Industrial Installations, Inc., of Mishawaka, Indiana, on a time and materials basis. Mr. Caldwell seconded the motion which carried. APPROVE LEASE AGREEMENT - WATER PURIFICATION EQUIPMENT - WASTEWATER TREATMENT PLANT Board Attorney Mary H. Mueller advised that submitted to the Board at this time is a Lease Agreement with Continental Water Systems of South Bend, 1126 East Jefferson, Unit B, Mishawaka, Indiana. This Lease Agreement indicates a monthly fee of $106.00 for the lease of water purification equipment. Mrs. Mueller noted that it was determined that it was more cost effective to lease this equipment which includes maintenance instead of purchasing this equipment and also paying an additional maintenance fee. Mrs. Mueller made a motion that the Lease Agreement, with the changes she made as indicated on the Agreement form, be approved and executed. Mr. Caldwell seconded the motion which carried.
