P.O. Box 1230 895 Technology Blvd, Ste 101 Bozeman, Montana 59711-1230 Bozeman, Montana 59718 Attention: Mr. Cody Flammond Attention: Mr. Shane Matolyak INTRODUCTION The purpose of this task order is to conduct tasks related to operations and maintenance of the Landfill Gas (LFG) handling system, Soil Vapor Extraction (SVE) system, and Air Injection (AI) system, and environmental monitoring of groundwater, methane, and leachate/condensate at the Bozeman Landfill (a.k.a. Story Mill Landfill). These activities will be conducted between July 1, 2026 and June 30, 2027 and are directed at meeting Montana Department of Environmental Quality (DEQ) Solid Waste rules and the requirements of DEQ’s June 6, 2014 letter requiring the City of Bozeman (COB) to conduct a Corrective Measures Assessment and implement remedial measures. This task order also includes engineering designs and drawings for expansion of the LFG system onto the lined waste cell, replacement of a non-functional LFG well on the unlined waste cell, and potentially an additional LFG well in an area of the unlined waste cell where methane capture could be improved. SCOPE OF SERVICES This task order includes the following work activities: • Task 100 – LFG/SVE/AI Systems Operations and Maintenance • Task 200 – Summer Groundwater Monitoring • Task 300 – Winter Groundwater Monitoring • Task 400 – Summer and Winter Groundwater Reporting • Task 500 – LFG Engineering Design for Lined Cell and Improvements • Task 600 – Project Management and Administrative Support The scope of work for these tasks is outlined below. Docusign Envelope ID: 989EB350-7CA1-83F3-81E0-E3F6A2C538D6 Task Order – 2026 to 2027 Groundwater and Methane Monitoring and Assessment Bozeman Landfill, Bozeman, Montana May 26, 2026 Page 2 of 5 TETRA TECH Task 100: LFG/SVE/AI Systems Operations and Maintenance This task is to provide operations, maintenance, and monitoring of the LFG/SVE/AI systems. This work includes regular monitoring of the system’s Supervisory Control and Data Acquisition (SCADA) system to ensure proper functioning and to identify and predict potential issues requiring maintenance. Periodic site visits will also occur to replace consumable items (i.e., air filters, regreasing bearings), adjust ventilation and heaters in response to changing weather conditions, observe well heads to identify and replace degraded components, and other similar operations and minor maintenance activities. Qualified subcontractors will complete major routine and unplanned maintenance as needed. Work completed by subcontractors will be billed directly to the COB and is not included in this Task Order however this work will be completed under the supervision of Tetra Tech and Tetra Tech’s labor expenses are included in this task. Other monitoring included in this task consists of quarterly measurements of gas concentrations and flow rates at individual LFG and SVE wells, AI well flow rates, and perimeter methane monitoring with subsequent reporting to COB and DEQ. Semi-annual monitoring and reporting of the leachate/condensate discharge to the municipal wastewater treatment facility will also be completed. Task 200: Summer (June and August) Compliance Groundwater Monitoring This task is to complete groundwater monitoring in accordance with the DEQ-approved Groundwater Sampling and Analysis Plan (SAP), Bozeman Landfill, Gallatin County, Montana prepared by Tetra Tech on July 14, 2023. This plan specifies monitoring of up to 24 locations (i.e., monitoring wells, a seep, and two water supply wells) for volatile organic compounds (VOCs), chloride, sulfate, nitrogen, and metals. The actual number of monitored locations varies by year as specified in the SAP. Additional samples are collected to assess quality control and quality assurance. This work generally consists of procuring disposable sampling equipment, rental of water quality meters, sample collection, and analytical laboratory analysis. Due to sample volume and equilibration constraints introduced by the DEQ-approved use of passive sampling devices, this work is split between two different events: one occurring in June and the other in August. Task 300: Winter Compliance Groundwater Monitoring This task is to complete groundwater monitoring in accordance with the 2023 Sampling and Analysis Plan (SAP) during the month of November or December. This work includes monitoring of 11 locations (i.e., monitoring wells and a seep) for Volatile Organic Compounds (VOCs), chloride, sulfate, and nitrogen. Additional samples are collected to assess quality control and quality assurance. As for Task 200, this work generally consists of procuring disposable sampling equipment, rental of water quality meters, sample collection, and analytical laboratory analysis.

Each report will include descriptions of the work completed and any deviation from the methods described in the 2023 SAP. The reports will also include analytical laboratory reports and tabular and graphical depictions of pertinent data, comparison of water quality data to regulatory standards, statistical analysis of constituent detections and trends in conformance with the U.S. Environmental Protection Agency’s (EPA) 2009 Statistical Analysis of Groundwater Monitoring Data at Resource Conservation and Recovery Act (RCRA) Facilities – Unified Guidance, data validation and interpretation, and recommendations for future work if warranted. Each report will be submitted to COB in draft form for review and editing prior to submittal to DEQ’s Solid Waste Division. Final versions of each report will be provided to COB in an electronic format that is compliant with the Americans with Disabilities Act (ADA) for posting to the COB website. Only portions of the report produced by Tetra Tech (i.e., typed text and applicable figures and tables) will be converted to meet ADA compliance standards. Handwritten field notes, analytical laboratory reports, and certain other portions of the reports are not possible to be converted by Tetra Tech. Task 500: LFG Engineering Design for Lined Cell Expansion and System Upgrades This task will include completion of engineering plans and drawings to be used for the construction of an expansion to the LFG system to recover methane from the lined waste cell. This work will include an evaluation of the feasibility of beneficial reuse of captured methane (i.e., as a heat source for the maintenance shop, source of liquified natural gas for sale to various consumers, etc.) which will help guide design of the LFG system. This task will also include design drawings for the addition and/or replacement of LFG wells on the unlined waste cell to increase the efficiency of methane collection from that source and also a drain system to address a leachate seep the forms seasonally along the western flank of the unlined waste cell. Tetra Tech will assist the City of Bozeman with preparation of Bid Requests and other construction contracting work under this task as well as Tas 600 (Project Management). Task 600: Project Management, Statistical Analysis, and Reporting Project management will include monthly administration / invoicing and progress reporting; semiannual budget forecasting and project summaries, updating the project Health and Safety Plan, preparation of an updated Operations and Maintenance Plan, scheduling of personnel, supplies procurement, training of personnel, and other related activities; communication with COB and DEQ; data management; and task order preparation for 2027-2028 project activities.
