One of these resources is the energy contained in the carbon-rich wastewater. The City is undertaking this important project to support production of renewable natural gas (RNG) from the biogas generated through the anaerobic digestion of wastewater solids. RNG is one of the key alternative fuels receiving attention and increased use in the U.S., largely because it is becoming more available and is less costly and cleaner burning. The Tetra Tech team looks forward to working with the City of Boulder to make this project a model for other communities. Tetra Tech employs dedicated professionals that can provide all the services to implement an RNG project, from permitting, engineering, equipment, construction, and startup, to ongoing operational support. These industry experts have provided design-build services for numerous successful projects that convert biogas into natural gas and vehicle fuel for a fraction of the cost of gasoline. At Tetra Tech, our company is best defined by the team members assigned to each project. Tetra Tech has assembled a team of internal experts skilled in the planning and design of processing anaerobic digester gas into RNG that are similar in scope and size to the City’s project and that integrate these systems into operating biological wastewater treatment facilities. These national leaders in biogas upgrading and biosolids processing possess unparalleled experience in RNG projects. The Tetra Tech team also includes staff from our Colorado offices who have worked previously at the 75th Street WRRF, specifically on the digester heating and mixing and biosolids processing systems. Tetra Tech has teamed with CGRS, Inc. of Colorado for its expertise and knowledge of local construction conditions. CGRS will serve as the construction contractor of the planned facilities and will meet the Colorado labor utilization requirements of the contract provided with the RFP. CGRS specializes in compressed natural gas (CNG) handling and storage facilities and is experienced in working at wastewater treatment facilities. CGRS is local to Colorado and is currently working on a similar biogas project in Longmont, CO, where a BioCNG™ unit is being installed. Tetra Tech and CGRS together have unparalleled knowledge of the Boulder area labor and materials markets, including the availability of specialized labor, equipment, materials, and labor and materials cost indices. While the depth of resources is essential for completing such a significant project for the City, the “boots on the ground” and an understanding of these relatively smaller biogas-to-RNG projects is what will make the biggest difference. The Tetra Tech team offers the complete package to perform all services that are required for the City’s project. Our team will be led by Mr. Paul Stout, P.E., who has 27 years of relevant project management experience, and includes personnel that are currently working together on similar projects across the U.S. Our task leaders for the biogas processing and digester modifications are experienced engineers with excellent understanding of the opportunities and challenges that lie ahead. Mr. Mark Torresani, P.E., is the inventor and patent holder on the BioCNG™ equipment skid the City has designated for use on this project. Mark has 33 years of experience and is a national expert in biogas-to- RNG upgrading projects. Mark will lead the biogas upgrades and commissioning of the project. He will work closely with Mr. José Velazquez, P.E., BCEE, who will lead the digester system modifications and upgrades. José has forty years of experience and has worked on digester heating and mixing projects across the United States and locally in Longmont and Edwards, CO. José has previously worked with the City at the WRRF on studies and designs leading to the upgrade of the dewatering facilities and digester support systems. Our team is supplemented by professionals who can bring experience and lessons learned from similar projects throughout the nation to deliver the best possible project team to the City. The team that will design, construct, commission, and assist Boulder in the long-term operations of the system prides itself in the work it completes and the long- term performance of the RNG/BioCNG™ systems they complete. Page 2 The City’s objectives for the delivery of the project and Tetra Tech’s commitment to them are detailed below. Reliability Tetra Tech and Tetra Tech’s BioCNG™ equipment are the leaders in the small biogas-to- RNG industry. This leadership position was developed by providing every client with a thorough and complete project, using proven equipment along with long-term support so that each project continues to be successful to this day. This project will be scheduled to eliminate interruptions to the digester process that interfere with digester operations. Efficiency Tetra Tech’s two pass BioCNG™ membrane system and project plan to utilize tail gas in a dual fuel burner will provide the greatest available use and value from the biogas. Tetra Tech will provide design and equipment that will maximize the biogas utilization efficiency and the runtime of the system, which we have learned are critical to the success of every project. Cost Tetra Tech routinely assesses the project elements regarding life cycle cost to assure that the project approach, along with other potential options, brings the greatest return to our clients. Tetra Tech is very familiar with small RNG/ BioCNG™ system operations and has worked over the past eight years to minimize operating costs, including the labor and media, to operate the system. Compliance Tetra Tech is aware of the need to complete the project with minimal impacts to the WRRF. We will address system changeover as the existing combined heat and power units are removed and replaced with new boilers. Tetra Tech will include temporary digester heating so the digesters have sufficient heat as the permanent facilities are constructed. We will also schedule the work to reduce construction during cold weather, reducing the risk of upsetting anaerobic processes. Ease of O&M Tetra Tech’s project plan and BioCNG™ equipment was specifically designed to be a low- cost, simple, easy to operate and maintain system. The BioCNG™ system was developed for ease of operations and maintenance (O&M). Having a clear understanding of how the BioCNG™ system operates and ties to the boilers is critical for long- term ease of operations. The Tetra Tech team will provide not only the equipment but the expertise to deliver a system that operates consistently and easily for years to come. Safety Tetra Tech takes safety very seriously and includes health and safety procedures in every aspect of the project’s design, equipment selection, construction, commissioning, and long-term operations. Our safety record is detailed further in this SOQ. Training: Tetra Tech provides O&M manuals, extensive training for clients to take over our project operations, and long-term assistance and support to assure that our clients are satisfied when the project goes online and throughout the project life. One thing we have learned is that personnel at WWTPs who will be operating the system should be involved in the design and startup process as early as possible. Tetra Tech will continue to assist Boulder with questions and reviewing site operations information long after the construction is completed. Tetra Tech has no findings of fault or liability in any civil suit for making any false claims or material representations to any public agency for the company and any of its principals. Tetra Tech has no assessed liquidated damages or failure of bid award based on the finding that the firm was not a responsible bidder. Appendix B contains a notarized letter from Tetra Tech’s surety verifying the availability of design- build payment and performance bonds of at least $5 million for this project and sample Certificates of Insurances from Tetra Tech’s insurance company demonstrating our ability to acquire and provide the minimum limits for the required insurance. We acknowledge receipt of Addendum 1 dated November 11, 2018. Page 3 DBC EXPERIENCE SUMMARY EXPERIENCE WITH INSTALLATION OF SIMILARLY- SIZED EQUIPMENT In response to a void in the marketplace for a smaller economical RNG system, Tetra Tech invented the patented BioCNG™ system, the first version of which was installed at the Rodefeld Landfill in Madison, Wisconsin in 2010, helping that client utilize RNG as a vehicle fuel. Tetra Tech is equipment agnostic and endeavors to evaluate all viable gas treatment technologies that may be suitable for a given site or where gas quality dictates other conditioning technologies. The dual pass BioCNG™ system is best suited for the City’s project. There are currently 14 BioCNG™ systems in operation, and they vary in size from 50 to 200 scfm of inlet biogas. Multiple units are deployed at a few sites to increase overall site capacity to process more biogas. Along with Tetra Tech’s extensive BioCNG™ system design experience outlined below, our team has also designed and installed many other large biogas-to-RNG projects. Tetra Tech has performed many projects like the City’s proposed project. Our project team’s experience working together on similar projects is summarized below. • Riverview Land Preserve, City of Riverview, MI (installed March 2013). The BioCNG™ system uses about 100 scfm of gas from the City’s Land Preserve Landfill, which will yield 450-550 gallons of gas equivalent (GGE)/day of vehicle fuel. A municipal CNG vehicle fleet is being developed as part of the project. The BioCNG™ vehicle fuel project is in addition to an existing landfill gas-to-energy (LFGTE) plant that produces 6.4 megawatts (MW) of electricity. • St. Landry Parish Solid Waste District, St. Landry Parish, LA (installed February 2011). Installed a BioCNG™ 50 unit in 2010. The Parish upgraded that unit and added a BioCNG™ 100 in 2015. Both projects were completed by Tetra Tech as design-build. Both projects included fast-fill, and the BioCNG™ 100 included installing a tube trailer filling-post and designing an off-site natural gas CNG fueling station with a decant facility to off-load RNG. The challenge for the second installation was to keep the initial BioCNG™ system running while the BioCNG™ 100 was installed. • Rodefeld Landfill, Dane County, WI (installed March 2010). The BioCNG™ biogas conditioning system economically produces biogas-based fuel to power Dane County’s parks and public works CNG vehicles, with the potential to expand and supply fuel to waste trucks and other County vehicles. The system was originally constructed to operate at a capacity of 100 GGE per day but was so successful it was upgraded to operate at a capacity of 250 GGE per day. The landfill’s BioCNG™ vehicle fueling station operates in conjunction with an existing LFG electrical generation system. The project won the prestigious 2011 Project of the Year Award from the U.S. EPA as part of the Landfill Methane Outreach Program (LMOP). • Persigo Wastewater Treatment Facility, City of Grand Junction, CO (installed April 2015). Design and construction of a BioCNG™ system to process WWTP digester gas into RNG for vehicle fuel, including integrating design with the existing WWTP and existing time-fill fueling station. Provided option to use treated RNG to fuel an existing on-site WWTP boiler system. The design integrated effective storage of RNG due to the available operating pressure range within 6-plus miles of dedicated pipeline. RNG use includes refuse trucks and other municipal vehicles. • Las Gallinas Valley Sanitary District, California (installed 2017). Designed WWTP digester biogas cleanup to RNG for use in boilers, for conversion to vehicle fuel, or use in combined heat and power microturbines. Designed fast-fill BioCNG™ stations to use RNG and a backup station using NG. As part of the project, interconnected with digester hot water loop, site electrical, site control, digester gas piping, and back up flare. • Clean World/Atlas Disposal CNG Station, California. Designed and integrated a Page 4 BioCNG™ biogas conditioning and vehicle fueling system at the SATS Organic Waste Digester. Provided fabrication, materials, and startup of two biogas conditioning skids for use with a Clean Energy CNG fueling station. Work also included site equipment layout and piping design, integrating with existing digester equipment, integrating the cleanup skid with the CNG fueling station, and supplying and integrating a flare system to destroy tail gas and digester gas. The design included RNG storage and compression to handle varying biogas inlet flow rates. • Blueline Transfer CNG Station, California. (installed 2015). Designed and provided startup of the BioCNG™ biogas conditioning and vehicle fueling system at the Blueline Transfer Facility Organic Waste Digester. The project included all system designs, equipment procurement, integration with existing anaerobic digesters, and a Clean Energy natural gas fueling station. A unique aspect of this project included the specification and integration of a custom boiler and heat distribution system that utilizes the BioCNG™ waste gas and the digester purge gas to provide process heat for the digester. • Randolph Farms Landfill, Indiana (installed 2018). Developed a BioCNG™ system to convert 200 scfm of LFG to RNG. Includes an RNG generation feasibility study, engineering and design, construction quality assurance (CQA), contractor management, equipment provision, and commissioning services. Cornerstone procured and supplied all major equipment, including a winterized, skid- mounted BioCNG™ 200 single pass gas conditioning and compression unit, an extra carbon media vessel to accommodate high volatile organic compound levels, and a skid- mounted BioCNG™ 200 chiller and control panel. EXPERIENCE WITH FIXED PRICE DESIGN-BUILD PROJECT DELIVERY The Tetra Tech team has led and assisted on numerous Fixed Price Design-Build Contractor (DBC) projects. This includes more than 30 biogas systems as large as 6,000 scfm. Over half of the BioCNG™ systems installed by Tetra Tech were completed as DBC. The DBC BioCNG™ projects led by Tetra Tech were all fixed price project delivery models. In addition to our work on biogas projects, Tetra Tech has worked on DBC contracts for landfills, refineries, mining operations, and municipal water systems. For example, Tetra Tech was the design partner on the Water Infrastructure Supply Efficiency (WISE) project for the South Metro Water Supply Authority in Douglas County, CO. The project included water treatment, pipelines, pumping, and storage facilities. Our experience working with private sector clients, such as a large, local refinery and various mining operations using the DBC approach provides us an excellent understanding of how this process works and how to make it successful. Tetra Tech strengthens in-house teams with subcontractors whenever specialized expertise is required. We do not perform any trade work (self- perform) but retain local qualified subcontractors and trades to implement the work, as is the case for the proposed work for Boulder. As previously mentioned, Tetra Tech has retained the local contractor CGRS, Inc, along with two subcontractors for electrical (Weifield Electrical Contracting) and HVAC (Murphy Company Mechanical Contractors) to accomplish the physical construction of the facility under Tetra Tech’s leadership and management. CGRS has provided design, construction management, commissioning and operations for a $10 million private water treatment facility in Western Colorado. This project included various engineering discipline subcontractors, direct design of the treatment train, pilot testing, and extensive permitting. Construction was a fast-tracked design-build contract through system deployment and successful project delivery. Communication is key to the DBC team management, and Tetra Tech will maintain an open and transparent process that supports the involvement of all team members. Because this project involves multiple disciplines and operations, ongoing coordination is essential to ensuring that everyone understands their roles and responsibilities and for dealing with issues on an ongoing basis. By communicating goals, Page 5 expectations, and project approach all members of the DBC team, from the Owner to the DBC contractor and any subcontractors and suppliers, will work as a team toward the City’s goals. In addition to open communication, the following Management Tools will be leveraged by the Project Manager, Design Manager, and Project Superintendent: • Reporting Tools: Tetra Tech will provide a one- page monthly progress report. • Cost Tracking and Control Tools: Our cost management and reporting systems provide Project Managers with the ability to execute projects independently but within a management approach that delegates decision- making and ensures safe, consistent, quality performance, on schedule and within budget. • Schedule Tracking and Control Tools: Tetra Tech will track and control the schedule with Microsoft Project by Work Breakdown Structure (WBS), and Construction trades and process description for Subcontractors Tracking and Control Tools. • Issue Resolution within Tetra Tech and Among Team Members: Tetra Tech projects, whether self-performed or subcontracted, are executed as an integrated team for maximum quality and delivery of all work on schedule and within budget. For each project, issues are identified early and resolved quickly using these key elements:  Active project management and oversight;  Clearly defined roles and responsibilities; and  Strong subcontract agreements. EXPERIENCE AND CAPABILITIES TO COMPLETE THE PROJECT The Tetra Tech team of engineers and technicians is familiar with the climatic conditions that can be encountered in Colorado. Much of the team that will be involved with the design and construction of the Boulder Project are based in Colorado or the upper Midwest and design systems specifically for construction and operations in cold climates. We have worked in the Colorado Rockies in Copper Mountain, Edwards, and elsewhere, so we are aware of the need to plan well in advance so that timing of construction is optimized when compared to climate and loading conditions. In fact, at the Eagle River Water and Sanitation, Edwards WWTP, we worked closely with the owner and contractor when upgrading their aerobic auto-thermal digestion system to avoid process upsets and periods where equipment was not available. As suppliers of the BioCNG™ biogas systems, we are also familiar with lead times for design, assembly, and delivery of this equipment. Typically, the gas processing equipment has one of the longest lead times, and that is likely the case for the City of Boulder. To minimize the risk to the schedule, we will begin preparing shop drawings and placing equipment orders as soon as possible to have all the equipment and systems at the earliest date possible for project construction. We understand anaerobic digester operations and how critical the heating and mixing systems are; therefore, we will focus on scheduling this work during warmer months when heating requirements are minimized. It is expected that placing an order for BioCNG™ equipment can be expedited because of the familiarity the Tetra Tech team has with the equipment. EXPERIENCE WITH DIGESTER HEATING MODIFICATIONS Tetra Tech has hands on experience with the digesters at the Boulder WRRF from several past projects. In the early 2000’s, we designed the heat exchangers and pumping systems to upgrade the heating loop. The Electrical Engineering Lead assigned for this Biogas Upgrade Project, Mr. Troy Moore, provided these same services on that project and assisted in the mechanical design by assisting in equipment selection. Troy is also experienced in heating, ventilation, and air conditioning systems at wastewater and water facilities. Approximately 10 years ago, Mr. José Velazquez, the WWTP Upgrades Task Manager, was the assistant project manager and prepared portions of the design of the modifications to various systems associated with the City’s anaerobic digester when Page 6 the new dewatering building was constructed. He also managed the City of Longmont’s anaerobic digester design, which included new digester heating and mixing systems for the conventional anaerobic digester at the Longmont WWTP. In addition to this local experience, he has studied, evaluated, and designed digester mixing and heating systems for anaerobic digesters in San Rafael, CA; Topeka, KS; Cheyenne, WY; Green Bay, WI; and other locations. Finally, the Mechanical Lead, Mr. Luke Ramirez has recently provided similar services for evaluating and recommending control upgrades at the Las Gallinas Valley Sanitary District in San Rafael, CA. FIRE CODE EXPERIENCE Safety is a core value at Tetra Tech; therefore, we are very proactive in addressing fire safety and adhering to National Fire Protection Association (NFPA) codes and standards. Tetra Tech staff have been instrumental in promoting awareness of NFPA requirements within the biogas industry, including the importance of developing and implementing “Purge Plans” to avoid having explosive mixtures of gasses in systems at startup and when performing maintenance. Tetra Tech has conducted several webinars open to biogas industry organizations and has given several presentations at national conferences on developing and implementing Purge Plans in accordance with NFPA 56. Within one month after NFPA 56 was issued as a provisional standard in August 2011, Tetra Tech developed and implemented its first compliant purge plan at the Hickory Meadows LFGTE Facility in Wisconsin. Since that time, Tetra Tech developed and conducted over 13 Purge Plans at gas conditioning plants and numerous others at LFG pipelines and compression to engine/turbine plants. Specific BioCNG™ Purge Plans completed include: • St. Landry Parish, LA (2 sites)—BioCNG™, on site CNG stations, and an off-site NG fueling station. • City of Riverview, MI—BioCNG™ and CNG fueling station. • Clean World (2 sites), CA—Food waste digester, BioCNG™, and CNG fueling station. • Zero Waste, CA—Food waste digester, BioCNG™, and fueling station • Las Gallinas Valley Sanitary District, CA— WWTP, BioCNG™, microturbines and CNG fueling. • Grand Junction, CO—WWTP, BioCNG™, pipeline and CNG fueling • Randolph Farms, IN—BioCNG™ and CNG fueling station. CGRS has been a member of NFPA for 17 years. They have been deeply involved in NFPA, IFC, and UFC for over 30 years.

S UBCONTRACTOR M ANAGEMENT P LAN Tetra Tech understands that appropriate planning, status reporting, and monitoring are key to successful subcontractor management and project completion. We utilize automated tools to track and report subcontractor performance on design and construction projects. This includes a company-wide planning tool called Tetra Linx, a financial management and cost accounting system that manages hundreds of ongoing contracts. This web-based system provides accurate and timely reports of current and forecasted costs at the program level, task order level, and task level, as identified by the task work breakdown structure. Tetra Linx is a powerful tool in tracking subcontractor performance on contracts with requirements like the City’s project. Tetra Linx was designed to accommodate contracts with multiple subcontractors and assignments by using a job cost work breakdown structure, cost categories, and cost elements to meet a wide range of contract requirements and program needs. Tetra Tech utilizes a suite of scheduling tools that can be customized to meet our clients’ needs and expectations that involve a high degree of integration across multiple tasks. These scheduling applications can be used not only to monitor subcontractor schedules, but also to provide the maximum amount of information to the Tetra Tech Project Manager and client staff concerning subcontractor schedule performance. Tetra Tech establishes control points and assessments on scope, budget, and schedule, and uses gathered information to timely communicate with subcontractors so that corrective action can be taken, or potential risk and issues can be mitigated.

For ongoing1 operations, revenue totaled $747 million, and revenue, net of subcontractor costs2 (net revenue), was $564 million, up 3% and 6%, respectively, year- over-year. Operating income for the fourth quarter was $43 million, and on an ongoing basis totaled $62 million, up 9% year-over-year. EPS was $0.51 on a GAAP basis; ongoing EPS totaled $0.75, up 19% year- over-year. Cash generated from operations was a quarterly record at $109.4 million, up 65% year-over- year. Backlog at the end of the quarter was a record $2.66 billion, up 9% sequentially and 5% year-over- year. Quarterly Dividend and Share Repurchase Program On November 5, 2018, Tetra Tech’s Board of Directors declared a quarterly dividend of $0.12 per share payable on December 14, 2018 to stockholders of record as of November 30, 2018. Additionally, the Board authorized a new program to repurchase up to $200 million of common stock. This new program is in addition to the $25 million remaining under the previously approved $200 million share repurchase program announced on November 9, 2016. Fiscal Year Results Revenue for fiscal 2018 totaled $2.96 billion and net revenue was $2.20 billion, both up 8% compared to the prior year.

Refer to Reconciliation of Revenue and Operating Results table for a reconciliation to GAAP. 2 Tetra Tech’s revenue includes a significant amount of subcontractor costs and, therefore, the Company believes revenue, net of subcontractor costs, which is a non-GAAP financial measure, provides a valuable perspective on its business results. Refer to Reconciliation of Revenue and Operating Results table for a reconciliation to GAAP. 2 Comments on Results Tetra Tech’s Chairman and CEO, Dan Batrack, commented, “Tetra Tech had a strong finish to fiscal 2018 and reported record high annual revenue, operating income, EPS, and backlog. We continue to see strong broad-based demand for our high-end consulting and engineering services, led by work for U.S. state and local clients, which has increased organically at a double-digit rate for more than two years. Record orders received in the fourth quarter drove our backlog up 9% from the prior quarter to another all-time high. These results give us confidence in our long-term outlook, which is reflected in our newly announced stock repurchase program and our guidance for another record year in fiscal 2019.” Business Outlook The following statements are based on current expectations.
