City Council Minutes 02-27-1995 SpecialMINUTES SPECIAL MEETING - MONTICELLO CITY COUNCIL Monday, February 27, 1995 - fi p.m. Members Present: Brad Fyle, Shirley Anderson, Clint Herbst, Brian Stumpf, Tam Perrault Members Absent: None A special meeting of the City Council was held for the purpose of further review of alternatives for expansion of the Monticello Wastewater Treatment Plant. Public Works Director John Simola reported that staff met last week to review ways to extend the amount of time before additions to the plant are necessary. He noted that if interim improvements are made before the phase I upgrade, it may be possible to delay completion of phase I construction until the year 2000 or 2001. Councilmember Herbst suggested that the Council consider a temporary moratorium on annexation to give the City additional time to consider this matter and to allow areas already in the city to fully develop. It was Mayor Fyle's view that perhaps fees should be increased to help pay for the expansion, which may in turn slow development slightly. Ron Hackenmueller of 113 Mississippi Drive noted his concerns about the rapid growth of Monticello, additional annexation of property, and how the city and the school district will be affected. John Simola, Public Works Director, reviewed the four alternatives for expanding the wastewater treatment plant that were discussed by Council at the January workshop: 1) Construction of an addition to the existing plant; 2) Construction of a "B" plant at a separate location, which would require trucking sludge to the existing plant; 3) Construction of a new plant; and 4) Phased construction of additions to the existing plant. Since phased construction appeared to be the most cost-effective method of expanding the plant, Jon Peterson of GSM presented information on the two alternatives for expanding the current wastewater treatment plant. The first alternative consisted of a trickling filter/activated sludge system, and the second alternative consisted of an activated sludge system. Both plans include interim construction of a primary clarifier estimated to extend the life of the plant to the year 2001, and then two phases of additional construction completed in the years 2001 and 2010. The estimated cost of the interim improvements is $620,000. The cost of the trickling filter/activated sludge alternative is estimated at $7,090,000 For phase T and $4,240,000 for phase TI for a total of approximately $11,330,000. Page 1 Special Council Minutes - 2/27/95 The cost of the activated sludge alternative is $9,290,000 for phase I and $1,900,000 for phase II, for a total estimated cost of $11,190,000. Peterson also noted that application to the State Revolving Loan Program can be made in the fall of 1995 as long as construction will not be occurring in 1995. Kelsie McGuire, PSG Manager of the treatment plant, noted that interim improvements would buy the City additional time far reviewing plant expansion alternatives and would also allow the City time to collect additional funds from new housing starts to help pay for the expansion. Odor control was also discussed, and it was noted that additional odor control methods would be included with phase I construction rather with the interim improvements due to the significant construction involved with odor control. It was the view of the Public Works Director John Simola, Plant Manager Kelsie McGuire, and Larry Anderson of RCM, that the trickling filter/activated sludge alternative is the most desirable due to better staged operational costs and easier handling of shock loadings. Simola requested direction from the Council concerning the interim improvements and which of the two alternatives they prefer at this time, as this information would allow the planning report to be completed. After discussion, it was the consensus of Council that the interim improvements are necessary, the trickling filter/activated sludge system appears to be the best alternative at this time, and the City should apply for design and construction funding through the State Revolving Loan Program. There being no further business, the meeting was adjourned. Karen Doty Office Manager [J Page 2
