WET Project Team has worked on dozens of vapor mitigation and landfill related projects over the past several years, and has developed timely and cost-effective solutions for its clients. We believe our team can efficiently and effectively address environmental concerns at the Bozeman Landfill, as well as provide a forward-thinking group to help mitigate existing and future exposure for the City of Bozeman. The WET Project Team will serve as an extension of your staff and offers several unique benefits to the City of Bozeman: • A Remedial Investigation/Corrective Action Team Second to None. WET has a qualified team with extensive knowledge of ground water and vapor mitigation issues, including previous work on the Bozeman Landfill project. Our staff has been at the forefront of vapor mitigation regulations and sampling procedures, and as a result, we will develop an investigation and corrective action plan that is technically sound. Our landfill experience spans several Rocky Mountain States with work at over 10 industrial landfills in Utah and Wyoming and municipal experience as close as the Park County Landfill. • A Proactive Approach to Addressing the Problem. Based on a review of project information, the City has taken a proactive approach to addressing impacts and engaging local landowners. Due to off-site impacts and a recent legal complaint, WET recommends that the City of Bozeman continue with a swift and aggressive approach to addressing the plume. WET recommends addressing contamination at the source, which will eliminate additional off-site migration and allow the City to maintain access and control of any corrective action infrastructure. • Proven Experience on Environmental Litigation Projects. WET's Project Team has long history of leading successful environmental litigation projects on behalf of its clients. Our Principal-in-charge, Dave Erickson, has served as Lead expert witness on several large and complex environmental sites, and our staff is used to working on sites with impacts to private land owners. As a result, our Project Team can effectively assist the City of Bozeman in developing a strategy to not only address and eliminate ground water and vapor migration, but also represent you in legal proceedings, if necessary. i Engineering Services Proposal—Bozeman City Landfill CAP Water&Environmental Technologies Figure 2 WET Staff Experience 'Table u 3 � 'o � w3cwo'> 3 � � �' � '� oa oo3 �3 U° o ° C7 •v .� °' 'in o c ° � _ ti W � a Oz F, o ° 'o ° ° Z aoi ' oncc UU0 ° � aoi N � °A'> - � c°' a°� Q � NC1r ° ° ow° °n- •° � abi o � O E ° Q o °°� Q '� U C y Q C7 U 'b v� ••-� y O A E chi c 'a. wa o.o 0 0 0 o i <a '� cFa oc � .EU c °' to o .c .

Today, our broad range of clientele includes local governments and state agencies;heavy industrial facilities, and private citizen groups. Specific to local governments, WET represents multiple other city/county governments on large-scale environmental issues, and we understand municipal operations and transparency requirements on public projects. WET personnel have designed, constructed, operated and/or evaluated hundreds of remediation systems for impacted soil, soil gas,and groundwater, including: 0 Soil vapor extraction(SVE); • Air sparge; • Multi-phase remediation; • Bioventing; • Funnel and gate capture systems; • Free product recovery; • Groundwater pump and treat; 0 Enhanced bioremediation; • In-situ chemical oxidation;and • Monitored natural attenuation. Some specific projects that highlight WET's relevant experience are listed below: Recent Work for City of Bozeman City of Bozeman—Landfill Support As requested by Michael Nicklin, WET reviewed the current data from investigation work at the Bozeman Landfill. Dave Erickson and Pat Thomson provided technical support on vapor intrusion and vapor sampling issues, identified relationships between ground water concentration, soil gas concentrations, and potential vapor intrusion pathways,and provided comment on the site conceptual model that was in place.This project involved data analysis and several discussions with Mr.Nicklin. City of Bozeman Municipal Separate Storm Sewer(MS4)Audit Bozeman Montana Although not directly under contract for the City, WET conducted a comprehensive on-site audit of the City of Bozeman's MS4 program (Permit #MTR040002) on behalf of MDEQ. WET personnel completed the audit according to EPA's MS4 Program Evaluation Guidance document and additional information required by MDEQ. One audit requirement was a Construction Site and Industrial Facility inspection, which was Page 4 February 2014 Engineering Services Proposal—Bozeman City Landfill CAP Water&Environmental Technologies conducted at the City of Bozeman Landfill. The landfill was inspected for signs of erosion, pollutants that could impact storm water runoff, and illicit waste water connections. No violations were observed. During the project, WET personnel gathered a firm understanding of the City's operations, and developed a positive working relationship with City personnel. Related Exueriience on Similar Proiects Landfill Remediation System Design and Monitoring Park County Montana WET characterized and continues to remediate a plume of chlorinated solvents that leached from the Park County Landfill. Remedial work included the design and installation of two groundwater remediation systems. One system is comprised of a multi-well air injecting network to strip volatiles, while the second system involves a funnel-and-gate groundwater capture system with air stripping of captured groundwater prior to release to a discharge trench. WET personnel conducted system maintenance and monitoring on a quarterly schedule, with two events coinciding with the semi-annual landfill monitoring. The systems have i performed well with chemicals of concern near or below MCLs. In addition to the remediation services described above, WET conducts monitoring and reporting associated with Park County's solid waste landfill to adhere to ARM 17.50 Subchapter 7. WET investigated, delineated and installed the current monitoring well system network and is responsible for maintenance of wells and dedicated well pump systems, monitoring of the system, and reporting as required by the rules of Montana. WETS current Sampling and Analysis Plan (SAP) for the site was completed in 2009 and is valid through 2014. Landfill Remediation System Design Operation and Monitoring Naughton Power Plant Wyoming WET personnel began working at PacifiCorp's Naughton Power Plant in 1993 with the permitting of the Industrial Waste Landfill under Subtitle D regulations. The plant is a coal-fired power generation facility in Kemmerer, Wyoming. Since that time, WET has been responsible for monitoring and reporting of ground water and surface water quality at the facility, replacement of monitoring wells, investigation of potential source areas, and the installation of a remediation system to collect seepage from a Flue Gas Desulfurization pond. WET currently operates and monitors the remediation system and fulfills WDEQ reporting requirements. Recently we have completed a detailed investigation into the landfill cover and provide permitting and financial assurance calculations for their active landfill. Sunburst Restoration Project Montana WET began investigation work in Sunburst, Montana in 2002 with a detailed Geoprobe® and air rotary drilling investigation to define a gasoline plume in a residential area. As a result of findings from data collection activities, a citizen's restoration group (SRG) filed suit against the PRP and were awarded a restoration and punitive settlement by the court that was later upheld by Montana's Supreme Court. After litigation,the SRG contracted with WET to provide remediation services to remove the plume from the residential neighborhood. WET instituted a two part remedial action: 1. Excavation of the shallow soil plume, and 2. Multiphase extraction of the deeper soil and ground water plume. This project involved permitting of a soil treatment land farm, treatment of contaminated ground water and discharge vapors from the remediation system, removal of abandoned underground storage tanks and product lines, and a detailed monitoring plan to track the effectiveness of remedial actions.

The company owns and operates two direct-push Geoprobe® drill rigs capable of collecting discrete soil, soil gas, and groundwater samples, as well as installing piezometers, groundwater monitoring wells, and soil gas probes. These rigs can also be coupled with onsite mobile laboratory equipment to provide rapid site characterization with reduced analytical laboratory costs. WET also employs an engineering survey crew, fully equipped with both standard optical and Global Navigation Satellite System (GNSS)survey equipment. Once survey data is collected,the mapping and data management specialists of WET's GIS department can develop customized GIS databases and software applications,tailored to fit specific project needs. Other field equipment in WET's inventory includes electric blowers and flow meters for SVE pilot tests, groundwater pumps and water level/water quality meters for groundwater monitoring, pressure transducers for aquifer tests; Geoprobe® tool strings for the collection of discrete soil gas samples at depth; and photoionization detectors for quickly assessing the presence of VOCs in soils. I In addition to our field capabilities, the scientists and engineers at WET utilize state of the art software applications for site characterization and remedial design. They include: • Groundwater flow and contaminant fate and transport models; • Environmental visualization system (EVS) software; and • AutoCAD Civil 3D design software. WET will utilize its specialized equipment and software on this project to facilitate quick and accurate data collection for the purposes of remedial design,construction oversight,and performance monitoring. 5.0 PROPOSED PROJECT APPROACH WET has developed a proposed project approach that will meet the City of Bozeman's intention to design and implement a comprehensive corrective action plan to mitigate the presence of vapors at, and in the vicinity of,the landfill, in a timely manner. Specific project tasks are described below. 5.1 CONCEPTUAL SITE MODEL 5.1.1 Project Database and Analytical Data Evaluation Project Database Personnel from WET's GIS/Data Management Department will evaluate the functionality of the current project database, as well as the quality of its data. Once the evaluation is complete, WET may recommend an alternate database structure and management system, if appropriate. One potential alternative may Page 8 February 2014 i Engineering Services Proposal—Bozeman City Landfill CAP Water&Environmental Technologies include the use of a customized GIS and database application that promotes the seamless, user-friendly collection of electronic field data. This approach has proven to be a very effective cost saving tool by reducing or eliminating the need to transcribe hand-written field notes and manually input data such as GPS coordinates. We will also evaluate compatibility of the existing database with the City's GIS system. Analytical Data Evaluation Once the quality and quantity of the current site database have been addressed, WET's technical team will evaluate the historical analytical data that has been collected from the site. Based on a review of site data from the City of Bozeman website, multiple ground water and soil gas monitoring events have been conducted on both the landfill property and surrounding residential areas. WET will review monitoring data to ensure it meets appropriate QA standards, as well as to determine whether previous assumptions related to the Conceptual Site Model (CSM) are correct (source areas, migration pathways, etc). As discussed in Section 4.1, WET has already reviewed site data and provided preliminary site interpretations, as requested by Mr.Nicklin. WET has also provided Geoprobe®services at the site for the current consultant. Only data collected in 2014 will need to be reviewed to bring the existing CSM up to date. 5.1.2 Conceptual Model Report Preparation WET will prepare a Site-Specific Conceptual Model Report that provides a summary of current site conditions. The report will be based on WET's interpretation of current and historical analytical data collected from the site and will evaluate the following parameters: • Contaminants of concern, • Source areas, • Fate and transport mechanisms, • Magnitude and extent of soil gas and groundwater plumes, and • Potential exposure pathways. The report will also evaluate multiple remedial alternatives, identify any data gaps that must be addressed prior to full-scale remediation system design, and recommend a preferred remedial option. Potential remedial alternatives may include soil vapor capture system(s) in preferential flow paths and/or near property boundaries or SVE/bioventing in source areas. WET will provide the CSM report to City of Bozeman personnel for review and comment. As with all projects, WET may propose and discuss with the City the possibility of combining the preferred remedial alternative with another beneficial action. Specific to this site, if it is possible to extract gas directly from the landfill waste and capture the methane gas for beneficial use, WET will recommend this as an alternative action. This would address the current problem with a solution that benefits the City, its residents, and the environment through generation of power from landfill gas. 5.2 REMEDIAL DESIGN 5.2.1 Corrective Action Plan Preparation Upon approval of the recommendations provided in the abovementioned CSM Report, WET will prepare a Corrective Action Plan(CAP)that presents a conceptual remediation system design and proposes methods to collect additional data to fill gaps and support the design. The CAP will also include a brief summary of the Site Conceptual Model,purpose and objectives of the proposed data collection effort,data quality objectives, Page 9 February 2014 Engineering Services Proposal—Bozeman City Landfill CAP Water&Environmental Technologies and a proposed schedule of field activities. The CAP will include a 30% design level of detail, and will be submitted to City of Bozeman personnel for review. 5.2.2 Supplemental Data Collection After the CAP is approved, WET's field team will conduct the subsequent data collection activities, which may include both passive and active sampling efforts. Passive sampling techniques may include shallow soil gas survey using GoreTM Modules or other passive sampling devices to evaluate the distribution of soil gas concentrations across suspected source areas and migration pathways. A passive survey may reduce overall sampling costs as large amounts of data can be collected with limited equipment and labor requirements. The objective of employing a passive survey is to identify areas of relatively high soil gas concentrations, or "hot spots,"which can then focus subsequent activities such as active sampling or remedial action. Active sampling techniques may include the use of WET's Geoprobe®rigs or a contracted drill rig to collect soil, soil gas, and/or groundwater samples from beneath the landfill and adjacent areas. Samples may be screened in the field to evaluate relative VOC impacts or submitted for laboratory analyses, and soil cores extracted from the site will be evaluated for their physical characteristics including grain size and shape. These properties will be used to determine the causes of elevated soil gas concentrations: either desorption from impacted soils, off gassing from impacted groundwater, migration from nearby source areas through preferential flow paths, or a combination of these. 5.3 DESIGN IMPLEMENTATION 5.3.1 Preliminary and Final Design Based on the conceptual design provided in the CAP, and utilizing historical and supplemental data collected from the landfill and surrounding areas, WET will prepare a preliminary remediation system design. The design effort will include a draft engineering report, 75% design drawings, and draft technical specifications. The draft engineering report will describe in detail the following: 0 Design criteria and alternatives; • Construction methods and sequence; and • System operation,maintenance,and monitoring procedures. The 75% design package will be submitted to the City of Bozeman and other required stakeholders for review and comment. WET will incorporate City and/or regulatory comments upon receipt and finalize the design. A 100%final design package will be completed and submitted to the City and appropriate regulatory agencies. At this time, WET will also complete a constructability review with the City to ensure that the design can be effectively implemented. 5.3.2 Project Bidding Per City of Bozeman and appropriate public bidding requirements, WET will perform all required project bidding activities. Tasks will include preparation of a project bid package containing an Invitation to Bid; Instructions to Bidders; Bid Form; Bid Bond; Agreement Form; Contract Conditions; Special Provisions; Measurement and Payment Details; Construction Specifications; Construction Plans; and any required attachments. Page 10 February 2014 Engineering Services Proposal—Bozeman City Landfill CAP Water&Environmental Technologies WET will schedule and attend a pre-bid conference, address comments from potential bidders, review qualified bids, and make a recommendation to the City of Bozeman regarding the selection of a qualified contractor. 5.3.3 Construction Engineering Once a contractor is selected, WET will provide turn-key contract administration and construction oversight services for the City of Bozeman. To the extent that City personnel wish to be included in the project, WET will work closely with City staff in its designated role. WET will assist with contract award, Notice to Proceed,and a pre-construction meeting. During construction, WET will serve as the City's Project Representative and will oversee all aspects of remediation system construction. Oversight activities will include project scheduling, safety and health updates, quality assurance (QA) testing and/or evaluations in accordance with project specifications, and communication with City of Bozeman personnel on any issues that arise. Contract duties will also include reviewing project submittals, budget tracking, processing pay requests, and recommending payments to City officials. A final inspection will be conducted upon substantial completion to identify and document punch list items that remain and to assess the overall quality of the work performed. 5.3.4 Post-Construction Activities Upon completion of construction activities, WET engineers will prepare a Construction Completion Report (CCR) summarizing all aspects of the construction project. The report will be included in a Project Completion Binder that will include all contract documents, specifications, submittals, as-built drawings,QA testing results, and relevant project correspondence. WET personnel will evaluate the baseline performance of the remediation system and optimize it. Once operational, WET will conduct routine performance monitoring on the system and make necessary adjustments. 6.0 NON-DISCRIMINATION AFFIRMATION FORM WET is proud to be an equal-opportunity employer and does not discriminate against prospective and current employees or subcontractors on the basis of race, color, religion, creed, sex, age, marital status, national origin, or because of actual or perceived sexual orientation, gender identity, or disability.
