3. Facility Plan 2000 Contract Amendment #3City of Kalispell Public Works Department Post Office Box 1997, Kalispell, Montana 59903-1997 - Telephone (406)758-7720, Fax (406)758-7831 REPORT TO: Mayor and City Council FROM: Jim Hansz, Director of Public Works SUBJECT: Facility Plan 2000, Amendment #3, Wastewater Treatment Plant Expansion PER MEETING DATE: April 1, 2002 BACKGROUND: Facility Plan 2000 for the City's water, sewer, storm drainage and wastewater treatment facilities identified a large number of urgently needed facility improvements. The planning study also concluded that the City's wastewater treatment plant will require expansion in approximately 2006. This expansion is necessary to accommodate growth and will occur approximately five years sooner than originally anticipated when it was designed many years ago. In response to this, the City Council directed staff to begin work immediately on the first phase of planning and preliminary engineering necessary to define the new facility. This will produce a Preliminary Engineering Report (PER) that will guide the final design and support the future solicitation of grants and loans to fund the construction. Work on the PER will be done via amendment of the current Facility Plan 2000 contract with HDR and Morrison Maierle. The amendment has been developed and is estimated to cost $127,875.63. A portion of this cost will be covered with grant funds. We have been notified by DNRC that the City was awarded a $10,000.00 grant for this work. In addition, we are applying for a $20,000 CDBG planning grant with high confidence it will be approved. RECOMMENDATION. Staff recommends Council authorize Amendment #3 to the contract for Facility Plan 2000. ACTION REQUESTED: MOTION APPROVING AMENDMENT #3 TO THE CONTRACT FOR FACILITY PLAN 2000 TO PREPARE A PRELIMINARY ENGINEERING REPORT ON EXPANSION OF THE CITY'S WASTEWATER TREATMENT PLANT AND AUTHORIZING THE CITY MANAGER TO ISSUE THE AMENDMENT.

Preparation for these meetings is included in this subtask. These meetings will be held at the KAWWTP. MDEQ staff will be invited to participate in the workshops, if desired by the City. Workshop notes will be prepared and distributed to all participants. The goal for the workshops is to provide overall project direction and consensus building on major decisions_ 1302 Update Existing Sewage Flows and Loadings. Update current flow and load data developed in recently completed Facilities Plan 2000 with most current flow and load 3/7/02 10:52 AM 1 DRAFP information from the KAWWTP. Revise per capita estimates for Kalispell and Evergreen wastewater systems for future planning. Prepare a special sampling program, in concert with Plant Staff, for additional evaluation of specific wastewater characteristics important to the operation and expansion of a BNR facility. Summarize and evaluate collected data for utilization in facility planning efforts. 1303 Develop Future Planning Characteristics. Utilizing recently completed Facilities Plar 2000 and updated per capita load data (subtask 1302), project KAWWTP influent flow and load values through 2025. Current and future treatment plant discharge and biosolids disposal requirements will be investigated and summarized_ MMI will meet with State DEQ staff in the Permits Section and the Technical and Financial Assistance Bureau to coordinate future planning criteria. The effects of proposed in -steam ammonia standard changes will be evaluated. 1304 Evaluate Capacity and Expansion of Existing Liquid Treatment Plant Unit Processes and Support Facilities. Each unit process and area of the KAWWTP will be evaluated with a spec emphasis on 1) current reliable capacity, 2) remaining life of existing equipment, 3) process/physical modifications for increased capacity, and 4) future application of technology. Non -process areas will be evaluated for current utilization and functionality, and future utilization and needs. An evaluation of current odor control facilities will be prepared and reoomrnendations wig be given as to the altematives for modification and expansion. Technologies discussed will be atomized mist scrubbers, packed tower scrubbers, and compost filter beds. Four areas will receive special evaluation: bioreactor and BNR process configuration, filtration performance and efficiency, UV disinfection capacity, and fermentation system configuration and design. Bioreactor and BNR Process Configuration — The existing BNR process configuration will be evaluated and compared to recent advances in BNR process understanding. Preliminary steady state computer modeling (Biowin) will be performed, calibrated to existing data as possible, to assist in identifying alternative process approaches and optimized zone sizing. Based on this evaluation, a re -rating of secondary capacity will established for planning purposes. Assist the City in identifying additional sampling to supplement existing data. A preliminary evaluation of fixed film and membrane technologies, as an enhancement to the current suspended growth technologies, will be performed. The existing aeration system will be evaluated along with modification to fine bubble diffusers. Filtration Performance and Efficiency —The capacity and performance of the existing filtration system will be preformed utilizing available data from the plant and investigation of performance at other facilities. Alternate filtration technologies will be evaluated and comparative upgrade and expansion scenarios will be developed, considering existing physical limitations. UV Disinfection Capacity — The existing ultraviolet disinfection system will be evaluated with a focus on expandability, upgrade to more current technology, and energy savings. 3/7/02 10:52 AM 2 DRAFT Newer technologies from Trojan (manufacturer of current equipment) will be compared to alternatives from other manufacturers. Fermentation System Configuration and Design — The existing fermentation system will be evaluated with a focus on current VFA production performance (and comparison to other locations), and expandability of the existing system for future flows and loads. Newer process technologies will be evaluated to maximize the use of the current tankage and minimize the need for additional facilities. Future fermenter configuration will be recommended. Additional facilities that could be required for compliance with more stringent TMDL limits will be identified and one feasible flow scheme will be carried forward for additional evaluation and cost estimating. 1305 Evaluate Capacity and Expansion of Existing Solids Treatment Facilities and Biosolids Disposal Planning. Each solids unit process of the KAVVWTP will be evaluated with a specific emphasis on 1) current reliable capacity, 2) remaining life of existing equipment, 3) process/physical modifications for increased capacity, and 4) future application of technology. It is anticipated that near term capacity needs for the major solids handling facilities will be met through additional operational hours of existing equipment. The current biosolids disposal program will be evaluated with a focus on future costs and viability. Investigate two alternate biosolids disposal approaches, including additional City -owned on -site or off -site processing prior to disposal. Identify specific actions or steps that the City should take to ensure a viable, long-term and cost effective biosolids disposal program. 1306 SCADA System Evaluation. Perform a cursory review of the capabilities of the existing SCADA system and develop a preliminary cost estimate for upgrade or replacement of the System. 1307 Develop Future Plant Expansion Alternatives. The information developed in earlier tasks will be used to determine future treatment plant capacity needs. Expansion alternatives will be developed that address plant capacity needs for a period through 2025. Alternative development will include evaluating potential construction phasing scenarios that would allow for staging of some facilities upgrades. Facility expansion needs will be evaluated for liquid and solid treatment processes, and for support facilities. 1308 Develop Project Costs, Compare And Select Alternatives. This task will further develop the alternatives identified in Task 1309 and prepare budgetary cost estimates. Alternatives will be evaluated on cost and qualitative factors and the apparent best alternative(s) selected. Based on input from the City, a potential project phasing scenario will be developed which identifies and documents projects based on needs - priority and funding options. A phased implementation plan will be developed and presented if appropriate. The effect of recommended project costs on utility rates will be analyzed and summarized to the extent necessary for funding agency requirements. 3/7/02 10:52 AM 3 DRAFT Potential project funding alternatives will be identified, including state and federal agency grant and loan programs. 1309 Environmental Analysis. This task will consist of an environmental evaluation meeting the requirements of the various grant and loan agencies identified in Tasks above. Specifically, this task will include an evaluation of environmental impacts of all infrastructure improvements to surface water, groundwater, air quality, land use, social impacts, economic impacts, and cultural and historical impacts. Comments will be solicited from various local, state and federal agencies concerning comments on the environmental impacts of the selected projects, based on the draft Facilities Plan, and these comments will be included in the final report. The level of effort budgeted for this task is based on the assumptions that there will be no expansion of the treatment plant site. 1310 Report Preparation and Documentation.
