HDR Kalispell Biosolids Facility Plant RFQ ResponseJune 192024 Proposal Wastewater Treatment Plant (WWTP) Biosolids Treatment-Disposal Project City of Kalispell June 19, 2024 Susie Turner, PE Director of Public Works 201 First Avenue East Kalispell, Montana 59901 RE: Wastewater Treatment Plant (WWTP) Biosolids Treatment-Disposal Project Proposal Dear Susie and Selection Committee Members: Once again, the City of Kalispell finds themselves at the forefront of changing environmental regulations combined with the possible loss of the City’s historical method of biosolids disposal, Glacier Gold Composting. The previous Biosolids Management Plan was an important initial step in realizing the next generation facilities, however there are several key issues based on current regulatory and other challenges that need to be addressed. Issues associated with PFAS, microplastics, and emerging contaminants in biosolids have become front and center for the City. Our proposed team brings expertise from around the United States not only related to biosolids management, but also the impact of these emerging contaminants on the decision making process related to disposal methods and technology selection. As will be demonstrated in our proposal, HDR has a proven plan for effective management of biosolids as well as the following major benefits. • Understanding the Impacts of PFAS/PFOS Results in Best Management Practices. The EPA currently has 704 contaminants of concern and this list is growing. Not only is this issue not going away, but could become more complex as data becomes available. As leaders in the industry, our project team will guide the City through the risk assessment process that results in the selection of practices and technology that allows the City to pivot as regulations change, the ability to leverage existing assets, considers the long-term impacts on sludge minimization, and the impact on the current treatment processes, in particular the liquid stream. These management practices in the current regulatory climate are proven and have been successfully implemented by HDR clients throughout the United States. • Understanding the Current Regulatory Environment Drives Long-Term Decisions. The initial planning process will build upon regulatory work already completed in other states. Michigan, for example, was one of the first states to take significant actions related to PFAS. Forty two facilities considered likely to have high levels of PFAS were sampled and based on this sampling land application limits, combined with a source reduction strategy, were implemented. The work that has been completed in Michigan and in other states such as Colorado can be used as a ‘yard stick’ for potential future regulations in Montana and thus how Kalispell manages biosolids going forward. The biosolids evaluation approach will also include a regulatory trigger-based approach to implement new solutions with ‘early wins’ for biosolids improvements. • Focus on Biosolids Dewatering and Sludge Minimization Creates a Strong Foundation for Future Management Challenges. Kalispell’s goal should be, to the extent possible, to minimize the amount of product produced. This may include weighing the advantages/disadvantages of WAS digestion and phosphorus recovery as it relates to reducing the total volume of biosolids. This is consistent with the steps that have been taken by other municipalities across the nation as they are looking to address their long-term biosolids management issues. In addition, careful attention to sludge feed rate and automation of dewatering controls are critical. We look forward to continuing our partnership with you on this critical project.

A recommendation was made for a biosolids improvements project and an implementation plan was developed using a phased approach. An estimated project cost was also provided. 3 City of Kalispell | Kalispell WWTP Biosolids Treatment-Disposal Project Our local delivery team will be supported by HDR's regional biosolids team and our national experts, bringing lessons learned from across the country to the City of Kalispell. Cedar Rapids Biosolids Master Plan & Improvements As the Cedar Rapids WPCF approached 40 years of service, the City initiated a comprehensive Biosolids Master Plan to plan for emerging regulatory requirements, and drive sustainable operations through energy efficiency and resource recovery. Following a baseline treatment process evaluation, the plan screened 12 treatment enhancement alternatives, pilot- and bench tested four technologies, and presented a roadmap of four future improvement phases. Key recommendations included: thermal hydrolysis and anaerobic digestion facilities; biogas reuse for revenue generation and renewable energy credits; intensification processes to reduce energy, increase biogas, and save space; and energy efficiency improvements. The broader planning strategy reviewed emerging regulations, cost of service, and provided outreach and strategic communication support. Subsequent to HDR’s Biosolids Master Plan, a HDR was selected by the City to design Phase 1A of the project. Cedar Rapids’ operations team was thoroughly integrated throughout the project in a series of workshops and site visits, for operability and maintenance enhancements. Pima County Biosolids Master Plan Update HDR updated the 2012 biosolids management master plan to include technologies to achieve sustainable long-term sludge processing and residuals management, including upgrading to Class A biosolids, for the County’s 50 MGD Tres Rios Water Reclamation Facility. The plan also considered alternative means of managing solids from the six other wastewater treatment plants operated by the County that currently transport their solids to Tres Rios for a total solids equivalent of a 94 MGD plant. Given the risks and vulnerabilities of their current disposal options, HDR was request by Pima County to create a road map for their biosolids that considers regulatory drivers, alternate and diversified end uses, and recommendations for biosolids process improvements. Pima County Decision Tool 4 City of Kalispell | Kalispell WWTP Biosolids Treatment-Disposal Project HDR collaborated with potential end users identified by the County for beneficial reuse of Class A biosolids, including mining industries, agricultural uses, and cement plants. HDR explored the opportunity with the County to supply a local cement kiln with biosolids as a potential fuel source prior to selecting an process alternative for their solids. Discussions were coordinated on behalf the County with the cement producers, as well as with local mining industries to propose biosolids as a potential remediation or reclamation of marginal lands, such as mine tailings. HDR also reached out to other state WWTPs to investigate composting methods these facilities have been implementing as biosolids management. The project included: • Risk analysis related to having a single outlet for biosolids disposal versus diversification, including Class A biosolids products versus Class B products, incineration options, and county operation versus third party operation) • Biosolids disposal option analysis, including landfill, land application – upgrading from Class B biosolids to Class A quality, incineration of Class B biosolids at a local incineration plant, and composting at the County versus third-party operation), • Biosolids production technology analysis for the Tres Rios Water Reclamation Facility, including thermal hydrolysis, heat drying, solar draying, and pyrolysis or gasification) • Site tours of facilities utilizing short-listed biosolids production technologies • Identification of proposed management facilities and permit requirements. • Development of capital and operations & maintenance costs and non-economic criteria for evaluation of alternatives. Columbia Falls Biosolids Dewatering and Management Plan HDR evaluated the City’s biosolids dewatering operations and developed methods for disposal of dewatered biosolids from the City’s WWTP. Work included evaluating biosolids production estimates based on the City’s wastewater flow projects and current biosolids data; analyzing potential biosolids market products; and identifying political and public constraints. HDR provided a long-term plan with three biosolids management options that included biosolids processing technologies, site considerations, ownership and operation scenarios, and end uses of the biosolids product. Bozeman Water Reclamation Facility Plan As part of the Water Reclamation Facility Plan, HDR analyzed biosolids management and disposal. An analysis of removing WAS from digestion and going to composting was considered. Additionally, an analysis of on-site composting and biosolids management was also prepared. Hamilton WWTP Phase 1 Improvements HDR provided preliminary and final design and construction management services for improvements to the City of Hamilton's wastewater treatment plant. Improvements included, among other things, secondary sludge thickening using dissolved air flotation, installation of a screw press for sludge dewatering, and sludge storage improvements. In addition a new aerated static pile composting facility was constructed including odor control. HDR also provided TMDL permitting and grant administration assistance. Flathead Regional Septage Treatment & Biosolids Composting Preliminary Design and Site Selection HDR provided preliminary design and site recommendations for a new regional septage treatment and biosolids composting facility. The project included design of a wastewater treatment plant to treat approximately five MG of septage per year, including effluent disposal. A new biosolids composting facility was designed to compost dewatered biosolids from the Cities of Kalispell and Columbia Falls, at the septage treatment plant. Preliminary design of odor control systems were provided for both the septage treatment and biosolids composting facilities.

CONTRACT UNDERSTANDING AND APPROACH Understanding The City of Kalispell (City) owns and operates a biological nutrient removal wastewater treatment facility which utilizes the modified Johannesburg process. In 2004, HDR developed a Preliminary Engineering Report (PER) for the City which included an evaluation of several biosolids handling and disposal alternatives. The recommendation at that time was to develop a dual disposal approach utilizing both the Glacier Gold composting facility and the Flathead County Landfill. In 2005, HDR completed Technical Memoranda 9 and 12 of the Basis of Design Report which evaluated biosolids thickening, dewatering, and loadout alternatives for meeting predicted 2025 biosolids loading conditions at the Kalispell WWTP. Technical Memorandum 12 concluded the dual disposal approach recommended in the 2004 PER was not measurably affected by the updated 2025 loading condition and, therefore, remained the preferred alternative. As such, the dual disposal biosolids method is currently used by the City. The City’s primary biosolids disposal method is to haul dewatered biosolids approximately 35 miles to Glacier Gold’s composting facility in Olney, Montana. The agreement with the facility is for 600 dry tons of dewatered biosolids annually. The contracted amount of biosolids is limited by the capacity of the equipment at the composting facility and, therefore, cannot be increased. The agreement with Glacier Gold also states the dewatered biosolids delivered to the facility shall be between 13-20% solids concentration; the City’s historical average has been 14-15% solids concentration. The City has a good working relationship with the staff at Glacier Gold. However, the long-term operation of the facility is in question. The second biosolids disposal method currently used by the City is to take the remaining dewatered biosolids to the Flathead County landfill. The agreement with the landfill is a verbal agreement only and could potentially be lost as an option if there is a change in management at the landfill, creating a tenuous situation. 6 City of Kalispell | Kalispell WWTP Biosolids Treatment-Disposal Project The City is also permitted by EPA to dispose of digested sludge on a 40 acre site south of Kalispell off Cemetery Road. The disposal site is used about every 5 years when digesters are emptied and cleaned. Because the City’s agreement with Glacier Gold is set to expire, the City would like to consider additional alternative biosolids management methods. The following is HDR’s approach to this project which will include an evaluation of alternative biosolids disposal methods for biosolids containing PFAS, microplastics, and any other emerging contaminants listed by EPA. Approach Biosolids Management and Technology Selection The framework for the City’s future biosolids facilities is documented in the May 2018 Biosolids Management Plan completed by HDR. In this plan, future dewatered biosolids quantities were estimated for planning purposes and alternative disposal methods were evaluated. An aerated static pile composting process was ultimately recommended. At the time this plan was completed the recommended solution was sustainable, minimized the risk of future changes in market outlets and regulations, and used responsible and cost-effective innovation to maximize benefits to the environment and the community. The previous Biosolids Management Plan was an important initial step in realizing the next generation facilities, however there are several key issues based on current regulatory and other challenges that need to be addressed. Issues associated with PFAS, microplastics, and emerging contaminants in biosolids have become front and center for the City as has the future potential impact on the public’s health and safety. What is unknown, and thus makes decisions around technology selection difficult, is determining how much PFAS in biosolids is acceptable depending on the proposed disposal methods as there is little data available on the long-term public health impacts. Related to this is the public perception of PFAS and related contaminants on whether any concentration other than zero is acceptable. A robust method for selection and procurement of the appropriate treatment technology and identifying the preferred disposal method will be critical for this project. HDR will develop a comprehensive list of all proposed biosolids technologies and process configurations. We will qualitatively assess the technologies and configurations that do not meet the goals of City nor would be supported by the evaluation criteria, including site constraints and maintenance of plant operations. We will then meet at a workshop to review the recommended shortlisted options to ensure buy-in from City staff before developing concepts. Keys to Successful Biosolids Management • Improve Biosolids Quality • Sludge Minimization • Leveraging Existing Assets • Understanding Impacts on Liquid Stream from Digestion • Phosphorus Recover/Mitigation • Energy Recovery As part of this process it is important to consider the keys to successful biosolids management as noted in the text above. Since the existing Biosolids Management Plan provides foundational knowledge, the proposed project approach will utilize workshops and brainstorming sessions that focus on how current issues that affect the planning that has been completed to date rather than starting from scratch. Our team will employ a collaborative workshop-based process to work with the City to move forward to the best solution together, based on a clear understanding of not only the cost impacts and operational tradeoffs between implementation options, but also emerging contaminants, PFAS and microplastics, and project schedule. Preferred plant improvements to integrate new processes into the City’s existing solids handling operations and facilities will be identified and developed. A detailed condition assessment of existing infrastructure will verify current conditions and identify equipment and processes to be reused or repurposed. The condition assessment within your active treatment facility will be conducted in a tiered fashion, using the least invasive method possible for accurate assessment while minimizing impact to plant operations. Key considerations for reuse of infrastructure include the cost of rehabilitation compared to the cost of replacement; the potential life remaining for rehabilitated versus new equipment; and impacts to construction sequencing and scheduling. Building upon our previous planning efforts, the HDR Team will take a holistic and pragmatic approach to evaluating biosolids management alternatives. Our approach will also emphasize providing flexibility to be able to respond to ever- changing regulatory and market conditions. The process will begin with the end in mind including a market study to determine the viable disposal methods for biosolids. Effective collaboration between City staff and the HDR team is the only way to develop a successful design concept. We will not only provide technical and economic guidance, but also facilitate “buy-in” for less tangible project attributes such as environmental impact and overall resiliency. Working with City staff, HDR will develop a Project Framework including a set of evaluation criteria and updating the criteria to reflect the biosolids market 7 City of Kalispell | Kalispell WWTP Biosolids Treatment-Disposal Project conditions and industry trends as well as established critical success factors: processing solids to generate Class A Biosolids, while retaining and optimizing existing facilities to accommodate beneficial reuse options. The implementation schedule for this project has become critical as Glacier Gold may be unable to take the City’s biosolids within the next two years. An alternative project delivery method could reduce the overall project schedule and should be considered. Additionally, alternative delivery methods may mitigate against some of the current infrastructure bidding environment challenges. Development of procurement requirements and contracts must capture the benefits of using the selected approach most effectively. Maintaining a strong and effective communications program will be advantageous in conveying important project details and benefits to the public. Strategic communication must engage and educate stakeholders about the project. Potential Issues and Mitigation Measures Strategic Communications As a result of unknowns, misconceptions, poor and potentially inaccurate information being conveyed to the public, there may be viable alternatives that just are not acceptable to the public (and therefore the City Council). Specifically, the viability of biosolids composting (depending on how it is disposed of) may come into question as a result of the presence…not concentration… of PFAS and other emerging contaminants in the biosolids. Like any form of pollution, it cannot be completely eliminated and there is some acceptable amount that does not pose a risk to public health and safety. The key here is that amount has not been determined yet. As a result, strategic communication and public education will likely be critical components to this project. HDR offers full-service public participation, analysis, and creative services that build more connected and sustainable communities. We craft strategies that engage and inform local communities about new infrastructure projects. HDR’s Strategic Communications team brings experience and expertise working with several Montana government bodies providing community outreach and stakeholder engagement on some of the most sensitive community challenges. We are supported by a national team of 250+ strategic communications staff and creative experts with the resources, talent and experience to deliver a clear and user-friendly message and collaborative problem solving, regardless of complexity. The following table summarizes the key issues that need to be addressed during the planning phase and HDR's approach to mitigate these challenges. KEY ISSUE HDR APPROACH AND BENEFIT Impact of Contaminants of Emerging Concern (CECs) on Technology/Disposal Selection Early collaboration between the City and HDR’s national experts will include a debrief on regulatory trends in the United States in order to provide the most current information on future potential regulations. Though no crystal ball is perfect, having previously addressed this issue all throughout the United States, our team is uniquely qualified to provide the best, most up to date information available to assist with decisions that are affected by this issue. Sludge Minimization One of Kalispell’s goals should be, to the extent possible, minimize the amount of product produced either through dewatering operations or through technology selection. This may include weighing the advantages/disadvantages of WAS digestion and phosphorus recovery as it relates to reducing the total volume of biosolids produced. Biosolids Dewatering Careful attention to sludge feed rate and automation of controls are critical. The slow speed/low pressure characteristics of a volute press make conditioning and flocculation of the sludge prior to the screw press key to the success of the dewatering process. Our past experience has taught us that these things are site specific and closely related to the quality of the material processed. Quickly Choosing a Biosolids Disposal Option In many respects much of the information in the 2018 Biosolids Management Plan is still current in terms of alternatives analysis. As a result, the 2018 Biosolids Management Plan should be utilized to the greatest extent possible. Doing this, combined with HDR’s knowledge of the WWTP, biosolids related issues, and past planning efforts will expedite the project selection process. Project Design Schedule Schedule must be factored into the alternative selection along with factors such as cost, operation and maintenance, etc. As a result, alternatives that include the need for additional land may be ranked lower or even deemed not viable should the issue with Glacier Gold become critical. As the alternatives are developed, a site selection process should be considered in conjunction with updating the 2018 Biosolids Management Plan. If the City’s 40 acres on Cemetery Road is a viable option, then this issue becomes less critical, but consideration should also be given to moving forward with key site analysis including survey and a geotechnical investigation as these may be the most important items on the schedule’s critical path. HDR has already invested significant time and energy into review of potential sites in the Flathead Valley for a biosolids management facility as well as the predesign effort for biosolids composting. This effort will give our team a significant head start in the design process should composting or a similar form of biosolids management be selected. Expedited Construction As the City and other communities in the Flathead and Mission Valley have recently experienced, the current project bidding environment is far from ideal. As a result, the City may want to consider an alternative form of project delivery including Construction Manager/General Contractor (CM/GC). The CM/GC process allows the City to be an active participant during the design process and make informed decisions on design options based on the contractor's expertise and feedback. The process also shortens the overall project schedule and increases price certainty. 8 City of Kalispell | Kalispell WWTP Biosolids Treatment-Disposal Project V.
