Please note that TREC, Inc. is a wholly owned subsidiary of Woodard & Curran, a full-service engineering and environmental management consulting firm.We have combined resources of approximately 800 professionals.This work will be performed by the Bozeman office with expert support as needed from the over 800 professionals of our company. We have spent a significant amount of time reviewing the project files and speaking with several people at the City and(with the City's permission)the Project Manager from the Solid Waste Program at the Montana Department of Environmental Quality (MDEQ). As a result of this work we have developed a good understanding of what the issues are and where data gaps exist for the development of a Corrective Action Plan (CAP) for the Landfill project. We believe TREC/W&C meets and/or exceeds all requirements as identified in the City's selection criteria,which is summarized in the table below. Category Meets Discussion Additional Information Criteria Provided Qualifications of Yes Highly qualified staff See Attachment A for Company and Staff locally and nationwide. company qualifications and Assigned to Project Section 3.0 and Attachment B for project team resumes.

Recent Work for City Yes TREC/W&C has not As discussed below we worked for City believe it is a positive for this therefore we are truly specific project. independent experts While technical capabilities are important we believe these are a given in today's consulting environment. TREC/W&C is very capable of solving the technical issues facing the City at the landfill, we know there are a number of other firms (not local but nationwide) that given the opportunity could also develop a suitable solution for this project. However,we believe there are differentiators between us and them. The following bullets highlight what we think are the four key issues and what differentiates us from other firms and why the City will be successful by hiring TREC/W&C: 1. Local Office-Our local presence.We have 30 professionals right here in Bozeman,with over 800 scientists, engineers and operators nationwide. Hiring TREC/W&C will allow the City to be successful by having local service with a deep national bench of experts. 2. Technical Expertize—As stated above we are one of several national firms that can provide the technical expertise to solve the problem of cVOCs migrating from the landfill. Hiring TREC/W&C will allow the City to be successful because of our ability to cost effectively bring the appropriate resources to bear on the project. 3. Stakeholder Communication/Risk Communication— We understand that it takes more than a sound technical approach to be successful. It takes effective stakeholder communication and buy in. TREC/W&C has proven success in these areas and will work diligently to engage all TREC,Inc. Engineering&Emironmcnlal�tnnagement JA A Woodard&Curran —,qko Company swrrtw stakeholders in an effective and positive manner. Hiring TREC/W&C will allow the City to be successful so in the end all stakeholders feel they have been heard and respected during the process. 4. New Set of Eyes — Based on our prior experience in similar situations, it is time to bring in an independent expert party to complete this scope of work. There is simply too much riding on this next phase of work to have any questions regarding the quality of the data. Hiring TREC/W&C will allow the City to get an independent opinion on current and past data collection activities. We are also highly qualified and understand how to develop a win-win strategy, allowing the City to meet its obligations in a cost effective and time manner. We would welcome the opportunity to meet with the City and/or selection committee to discuss our proposal, experience, and our ideas around working with the City to develop a winning strategy for the successful completion of this project.

There are two cells,an unlined cell which was operated from 1970 to 1995 and a lined cell which was operated from 1995 to 2008.Both cells are now closed. In the December 1997 Landfill Gas and Groundwater Monitoring Report by Tetra Tech, it was reported that methane concentrations in monitoring devices BLG-1, BLG-2, BLG-3,BLG-4, BLG-7, BLG-8, BLG-9S and BLG-9M measured 100% of the LEL during both October and December 1997 monitoring periods. A landfill gas extraction system was installed on the unlined cell in 1997 and has been operating since that time.Combustible gas from the unlined cell is burned at a candlestick flare located at the site. In 2007, Tetra Tech published a Landfill Gas Extraction System (LGES) Evaluation and concluded that: "the LGES will meet its intended purpose of preventing offsite migration of landfill gas and improving groundwater quality over time. As a result,no additional corrective actions are warranted." In a letter to the City of Bozeman dated November 18,2011, the Montana Department of Environmental Quality (MDEQ) requested further "plume" characterization due to groundwater protection standard exceedances and increasing contaminant trends. Partly in response to the letter referenced, Tetra Tech installed gas probes in March and May 2013. Soil gas probes BSV-1 through BSV-12 were installed south of the landfill adjacent to existing methane monitoring points and groundwater monitoring wells as well as within residential areas. On June 26`h 2013, the City of Bozeman conducted a Neighborhood Meeting to discuss recent findings of soil gas in the closed city landfill site. Tetra Tech gave a presentation providing results of the soil gas study that shows elevated levels of Volatile Organic Compounds(VOCs)in the soil gas in the vicinity of the landfill. Vapor samples have been collected in the following areas: • Sub-slab samples in developments designated as Bridger Creek Phases 11 and III. • Indoor air samples have been collected in Bridger Creek Phase III. Based upon the sampling results,the City has installed sub-slab depressurization systems for the Phase III homes as a precaution to inhibit the potential for migration of VOCs associated with the landfill into the Phase III homes. A schematic in the Tetra Tech Neighborhood Meeting presentation on August 27, 2013 shows the VOCs in landfill gas leaving the site and approaching Phase III homes in the subsurface. Tetra Tech's conclusions for the presentation include ultimately controlling or eliminating the source of VOCs on the landfill property. Additional site characterization will be required to develop a design for the remediation approach. The City of Bozeman is currently preparing to install additional probes and monitoring wells on the landfill property that will support remediation evaluation and design. Section 2.0: Conceptual Approach Based on the Request for Proposals (RFP)provided by the City of Bozeman,TREC/W&C has prepared a conceptual approach to a Corrective Action Plan for the Bozeman Landfill. As outlined in the RFP,there are three tasks requested: • Task 1: Develop Updated Site Specific Conceptual Model • Task 2: Develop Preliminary Recommendations for a Corrective Action Plan(CAP) • Task 3: Design Implementation The schedule to complete the tasks described below is provided at the end of this proposal. Assuming notice to proceed by April 1, 2014; we anticipate having Task 1, the Site Conceptual Model (SCM) City of Bozeman RFP for Corrective Action Plan Services—Bozeman Landfill Page I IREC,Inc. Enginccring S Enrironmcntal Alrnnecment JAL A NV'oodard&Curran Company '.— completed by April 18;Task 2,the Preliminary Recommendations for the CAP completed by July 30,2014; and Task 3,the Design Implementation by October 1,2014. Task 1: Site Conceptual Model: TREC/W&C will prepare an updated SCM using existing and newly acquired data from the various landfill remedial investigations. In preparation for responding to this RFP we have collected and reviewed all available information at the City of Bozeman (City) engineering department and available information at City Hall. We have also, with City permission, contacted John Collins at the MDEQ solid waste group to gain a perspective on what the State sees as data gaps and where they see the project going. While TREC/W&C has not completed the updated SCM, we have good start and believe we can complete this task quickly after notice-to-proceed. The goal of an updated SCM is to identify the (1) source of chlorinated volatile organic compounds (cVOCs),(2)migration pathways,(3)existing and potential exposure routes,and(4)existing and potential receptors. TREC/W&C will prepare an updated SCM in accordance with EPA guidance (OSWER Final Guidance for Assessing and Mitigating the Vapor Intrusion Pathway from Subsurface Sources to Indoor Air, April 11, 2013) and MDEQ guidance (Montana Vapor Intrusion Guidance, April 22, 2011). Data evaluation will follow the `Multiple Line of Evidence' approach favored by both MDEQ and EPA. It is our understanding that the City is currently installing nine additional soil borings/wells along the southern edge of the landfill, along a line between the unlined cell and the Bridger Creek Neighborhood. We assume, based on our review of existing data and conversation with the City and the MDEQ that the goals for this investigation are to address apparent data gaps in the vadose zone (unsaturated soil) and shallow and deep saturated zones to identify possible migration pathways from the closed landfill to the local residential housing. This information will be critical for finalizing the SCM. Task 2:Corrective Action Plan: The primary focus associated with Task 2 will be to develop preliminary recommendations for corrective action to mitigate migration of cVOCs from the landfill to adjacent properties. This will include evaluation of remedial technologies to develop a conceptual remedial approach. This may include more than one alternative. Based on the updated SCM and discussion with the City and MDEQ,TREC/W&C will identify data gaps for completion of the CAP, if any remain after the newly completed soil borings and monitoring wells are installed and sampled(as discussed above in Task 1). The need for additional data will be evaluated based on possible data gaps identified for remedy evaluation and selection. This may include additional sampling/testing of existing infrastructure, testing of landfill gas extraction wells or soil profile and geotechnical data should a barrier wall be considered. A Work Plan will be developed to obtain this data and be developed consistent with EPA and MDEQ guidance.Key steps will be taken to ensure data quality objects(DQOs)are clearly established so that data obtained from this supplemental investigation will meet the quality and quantity needed to meet its intended use. The end use of these data will be for evaluation of remedial alternatives and eventually the remedial design. Task 3: Design Implementation: Working closely with the City and in consultation with the MDEQ, TREC/W&C will make a recommendation for a final remedy. The criteria for remedy selection will follow both EPA and MDEQ guidance for development and remedy selection. It is our intent to meet the criteria outlined in the EPA Feasibility Study criteria and MDEQ 75-10-72 however, this will be a focused evaluation. We intend to identify 3 or 4 alternatives and evaluate each against the regulatory guidance criteria and therefore keep this a thorough but focused evaluation. We will work closely with the City to identify a final remedy and then meet with the MDEQ to finalize the design requirements for the selected remedy. City of Bozeman RFP for Corrective Action Plan Services—Bozeman Landfill Page 2 TREC,Inc. F.nginecring&F,mirenmcntul�lunukcntcnt A Woodard&Curran Comp ny Remedy Design: The next step will be to complete the design for the selected remedy. It is our intention to develop a preliminary design (30%) which will be provided for review and comment. Comments will be incorporated into a final design document. Bidding_Services: During completion of the final design, we will be preparing bid documents for construction. TREC/W&C will aid the City in bid evaluation and contractor selection. Construction Engineering: Once the contractor is selected, TREC/W&C will provide contract administration,construction oversight and management. Post-Construction Reporting: TREC/W&C will provide record drawings and performance monitoring as part of project closeout.

We were identified as problem solvers and closers; we managed the project with the end goal in mind. Please see Attachment C for more detailed descriptions of these projects. Bendix.MI: Large TEC/PCE plume migrating under a subdivision of 52 expensive vacations home on the shore of Lake Michigan. Keys to success were (1) getting EPA on board with the monitored natural attenuation(MNA)remedy and(2)effective risk communication with the local residents. This built a level of trust between the PRP,regulators and community that allowed the project to move forward quickly and be viewed as a success by all stakeholders. Rouses Point NY: Former pharmaceutical manufacturing facility resulted in TCE/PCE plume extending below several dozen homes. Keys to success were: (1) careful and detailed site characterization for identification of preferential pathways in the subsurface which allowed cVOCs to migrate long distances from the source, and (2) installation of 56 residential sub-slab depressurization systems in area homes. These two critical path items helped resolve what could have been a very litigious condition allowing the project to move forward with source isolation and source removal activities. Keys to Success: High levels of communication and trust between all stakeholders and excellent risk communication skills by TREC/W&C staff. Call David Tarnowski of Robert Bosch LLC at 248-876-2475 and ask him how hiring TREC/W&C to manage the technical and,more importantly,community relations allowed his project to be successful. Feasibility Studies and Design The Confidential Site was a former manufacturing facility that was redeveloped into residential condominiums. Legacy contamination resulted in a complete vapor intrusion pathway for cVOCs, particularly trichloroethene(TCE),within residences.Tight deadlines driven by regulatory and homeowner concerns led to an investigation and mitigation of Site conditions conducted over a nine month period, which has better positioned the Site for permanent closure. Keys to Success: State of Art understanding of vapor intrusion risk assessment approaches and techniques and careful consideration of remedy selection coupled with a successful remedy selection approach. Call Jeff Boutin of VH Blackinton at 800-6994436 and ask him about how the TREC/W&C focused feasibility study and detailed design allowed the project to proceed while mitigating vapor intrusion to indoor air. Landfill Closure Gas Management A recent project that is very similar to the Bozeman Landfill is the landfill in Lawrence,MA. This landfill had been closed years before we worked with the city to redevelop the landfill into a 4,000 seat minor league baseball stadium. The State had cited owner for off-site migration of landfill gas to an adjacent neighborhood. Keys to success:Ability to deliver on a compressed schedule.Delivered within three months for all permits and preliminary design for waste consolidation and relocation,management of off-site migration of landfill gas, and remote operation of the landfill gas treatment system via advance telemetry/communication system.

Despite years of subsurface inves- - EPA Symposium on Green tigations the sources of these plumes had eluded previous investigators.After we Remediation, 2008, were hired for the project, Karl integrated cone penetrometer(CPT)data and sample collection technologies, coupled with the advantages of an on-site mobile laboratory, and the two source areas were quickly identified. The source of the eastern plume was identified as a DNAPL that resides just below the water table,while the source of the western plume was identified as a DNAPL located at 80 feet below the ground surface. Upon completion of the source identification, the site conceptual model was completed and migration pathways evaluated including groundwater, soil gas, indoor air and surface water exposures routes.The western plume migrates below a 50 plus home subdivision on the shores of Lake Michigan. Stakeholders and community relations have been a key component to our success. Having completed the reme- dial investigation, we worked with our client, the Michigan DEQ, and the U.S. EPA to outline potential remedial strategies. This review team selected natural attenuation as the remedial alternative that will most effectively meet the NCP evaluation criteria used by EPA for Superfund.

Former Manufacturing Facility, MA—Vapor Intrusion Assessment/Mitigation and Bio- Augmentation Groundwater Treatment The Site was a former manufacturing facility that was redevel- oped into residential condominiums. Legacy contamination has resulted in a complete vapor intrusion pathway for chlorinated volatile organic compounds(VOCs),particularly trichloro- ethene (TCE),within residences.Tight deadlines driven by regulatory and homeowner concerns led to an investigation and mitigation of Site conditions conducted over a nine month period,which has better positioned the Site for permanent closure. Soil, groundwater,soil vapor, indoor air and ambient air data were collected and evaluated to refine the conceptual site model,which indicated that VOCs in soil(present in vapor phase)were the likely source of VOCs in indoor air,rather than the typically-suspected shallow aquifer.A risk-based approach that considered interior(background)sources of VOCs and both short and longer term risk-based thresholds was used to select the Site-related chemicals of potential concem (COPCs) in indoor air and to identify individual units requiring mitigation through the installation of individual,active sub-slab depres- surization systems(SSDS). Open dialogue with the residents, the condominium association and regulators was a key aspect in implementing data collection and SSDS installation plans. Comparison of data from pre-SSDS installation data to post- SSDS installation indicates that the SSDS in all affected units are effectively mitigating exposures to TCE,the primary con- taminant of concern, thereby bringing the Site closer toward closure. VOCs were also present in groundwater within a portion of the Site at concentrations exceeding state upper concentra- tion limits(UCLs).To reduce VOC concentrations,Woodard& Curran implemented a remedial plan that entailed the subsur- face injection of Anaerobic BioChem®(ABC), a slow-releasing mixture of microbial nutrients(lactates,fatty acids, and a phos- phate buffer)proprietary to Redox Tech of Attleboro, MA.The initial treatment resulted in positive overall VOC reductions in the source area;additional targeted treatments are planned to further reduce VOC concentrations to ultimately achieve reme- dial goals. P263 CITY OF BOZEMAN WOODARD & CURRAN Cony ©l Bozzsman Attachment 1 Proposal February 20,2014 \\NTAPS-MADISON\MSN-VOL6\-\WPMSN\PJT2\214122\999Oi P2141229990-OO1.DOC%1214122.9990 cGutny of Bozeman Proposal for Bozeman City Landfill Corrective Action Plan Background The City of Bozeman has operated a landfill at the current site since 1970. There are two cells, an unlined cell which was operated from 1970 to 1995 and a lined cell which was operated from 1995 to 2008. Both cells are now closed. A landfill gas extraction system was installed on the lined cell in 1997 and has been operating since that time. Combustible gas from the unlined cell is burned at a candlestick flare located at the site. The City of Bozeman(City)has detected volatile organic compounds (VOCs)in the groundwater and in soil gases both beneath and adjacent to the landfill. Groundwater in the site vicinity is contaminated with low levels of dissolved chlorinated volatile organic compounds(CVOCs);particularly tetrachloroethene(PCE) and its breakdown products,trichloroethene(TCE), cis 1,2 dichloroethene,and vinyl chloride. A plume of these constituents is migrating away from the site towards the Gallatin River. Based upon the sampling results,the City has installed sub-slab depressurization systems for newly constructed homes as a precaution to inhibit the potential for migration of VOCs associated with the landfill into the homes. The City wants to design and implement a more comprehensive corrective action plan for submission and approval by the Montana Department of Environmental Quality (MDEQ)to control/mitigate the presence of vapors at, and in the vicinity of,the landfill. Approach Considering the site history and details,TRC concludes that the landfill,with its relatively small size and older refuse, would have relatively low landfill gas (LPG) generation rates. The observed gas migration is likely caused by pressure buildup within the landfill;however, a buildup of LFG pressure would not be anticipated unless the existing LFG collection system is undersized or performing poorly. To understand the site conditions, contaminant source and movement, and the existing LFG system TRC proposes developing a Conceptual Site Model(CSM). Based upon extensive experience with landfill VOC remediation,TRC recommends that the City approach the solution by considering a balance between active control,using the existing LFG collection system, and passive remediation of the groundwater. The project team envisions a phased approach beginning with an evaluation of the performance of the existing LFG system followed by an evaluation of the hydrogeochemical environment. The analysis of the existing LPG system would begin with an evaluation of a radius of influence test of the landfill extraction wells. Then,if necessary, additional wells and laterals to the existing wells would be considered as conditions and budget dictate. Later, depending upon the pressure drop calculations and end well vacuum measurements,a larger motor blower unit may be needed to create a negative pressure inside the landfill to prevent future migration and to draw migrated gases back to the landfill. Preliminary review of the site hydrogeochemical environment indicates the aquifer is conducive to use monitored natural attenuation(MNA) as at least part of the site remedy of the CVOC plume. TRC has extensive experience with MNA as well as the characterization,enhanced bioremediation, and chemical oxidation of CVOCs. This process involves working with the geochemical and hydrogeologic environment to craft a site- specific remedy. This combined approach will provide source control and monitoring to determine effectiveness. Improving the existing gas collection system will create vacuum towards the landfill as the point of control which will prevent LFG from migrating off-site and possibly draw the migrated landfill gases back to the landfill. Sampling for February 20,2014 1 \\NTAP&MADf5ON\MSN-VOIb\-\WPMSN\PJT2\214122\9990\P2]41229990-0O1.DOGr 1214122.9990 Catty ®i} Bozeman MNA will provide a method to monitor VOC concentrations in the groundwater while implementing the active control. TRC will perform an Assessment of Corrective Measures incorporating the approach described above, to review alternative corrective actions,provide recommendations for corrective action(s)selection, and develop a preliminary design. TRC anticipates that a Selection of Remedy Report submitted to the MDEQ will be needed to implement the corrective action(s). After approval of the Selection of Remedy Report,the selected corrective actions can be implemented. TRC's recommended scope is organized into four tasks: 1. Develop a Conceptual Site Model. 2. Perform an Assessment of Corrective Measures. 3. Develop a Selection of Remedy Report. 4. Implementation of Corrective Action. Scope of Services Task 1 Develop a Conceptual Site Model To develop a conceptual site model(CSM)TRC will: ■ Perform a desktop study of the available site information and landfill analytical database ■ Communicate the needs (if any) for additional data collection with the City. ■ Develop a LFG and groundwater sampling and analysis plan to evaluate the source of VOC's detected in groundwater and in homes [biogenic(landfill/swamp gas),thermogenic(natural gas), or other origin]. ■ Perform field sampling, observation of site conditions, and LFG system evaluation. ■ Perform laboratory analysis of the gas samples for various gas characteristics (i.e.,elemental analysis) and stable isotopic analyses. — The elemental analysis involves testing for helium, carbon dioxide,individual volatile organic compounds (VOCs),sulfur compounds, and straight-chain aliphatic hydrocarbons. This analysis will be performed by Air Toxics Limited laboratory. — The stable isotopic analysis involves determining carbon C12 to C13 and hydrogen H1 and H2 ratios that will indicate the source of the carbon and hydrogen in the methane. If the sample contains significant amounts of carbon dioxide,the laboratory will also perform a method for biogas detection. This analysis will be performed by Isotech Laboratories. ■ Evaluate the data,including: carbon and hydrogen isotope content as compared to standards for various types of gases containing VOCs, comparison of migrated gas to raw LFG, groundwater quality, hydrogeological conditions, and performance of the existing LFG system. ■ Develop a CSM Report describing the site conditions,hydrogeochemical conditions,interpretations, contaminant source,movement, and major assumptions. ■ Provide a draft of the CSM Report to the City of Bozeman for review prior to submission to MDEP. February 20,2014 2 1\MAP&MADISON\NISN-VOLE\-\W PMSN\PJT2\214122\9990\P2141229990.001.DOCX 1214122.9990 City of Bozeman Task 2 Perform an Assessment of Corrective Measures Considering the site conditions and conclusions of the CSM Report,TRC will prepare an Assessment of Corrective Measures meeting the requirements of the Administrative Rules of Montana(ARM) 17.50.1308 including: ■ An evaluation of the effectiveness and cost of several corrective action alternatives listing advantages and disadvantages of each. ■ An evaluation of MNA effectiveness. ■ A preliminary design based on the selected alternative. ■ An opinion of probable cost for the preliminary design. ■ A proposed implementation schedule. ■ A draft of the Assessment for Corrective Measures prior to finalizing. The Assessment of Corrective Measures will likely include: ■ Phased gas well field layout enhancements. ■ Modified line sizing/pressure drop calculations. = Modified flare sizing calculations and performance standards,if necessary. • Modified blower sizing calculations and perfonnrance standards, if necessary. ■ Estimation of natural attenuation timeframe. ■ Groundwater monitoring plan, if necessary. ■ Additional groundwater monitoring locations, if necessary. ■ Active groundwater remediation system design,if necessary. Task 3 Develop a Selection of Remedy Report TRC will develop a Selection of Remedy Report meeting the requirements of ARM 17-50.1309 in order to implement the corrective actions. During this task TRC will: ■ Assist the City during negotiations with the MDEQ ■ Develop a construction Quality Assurance/Quality Control(QA/QC)Plan,if necessary • Provide a draft Selection of Remedy Report to the City to review prior to finalizing ■ Submit the final Selection of Remedy Report Task 4 Implementation of Corrective Action After approval of the Selection of Remedy Report,TRC will assist the City during bidding,construction, and monitored natural attenuation. TRC's proposes to: ■ Develop final plans and specifications for the selected remedial design. ■ Provide bidding assistance to the City of Bozeman including: developing bid documents,leading a pre-bid meeting, responding to requests for information, and providing technical bid analysis. ■ Provide construction observation and oversight to document the construction. — Construction observation will be performed by a Resident Project Representative (RPR). The RPR will have support from the design staff intimately involved with the remedial design. The RPR will work with the contractor and effectively communicate when deviations to the plans and specifications are observed. February 20,2014 3 \\NTAPB-MADISON\MSN-VOLE\-\W PMSN\PM\21412219990\P2141229990-001.DOCX 12141229990 City 0 Bozeman TRC will develop a Construction Documentation Report that provides a description of the construction activities, summarizes the RPR's observations, and confirms that construction was completed in substantial conformance with the plans, specifications, and QA/QC Plan, describing exceptions where applicable. The construction documentation report will provide as-built drawings. Provide monitoring,evaluation and reporting services to document the MNA. A phased approach to remediate the gas migration and the CVOCs has been presented above. Each component sequentially leads into the next step allowing for an efficient remedial design to be implemented to address the conditions at the site. Project Schedule The schedule outlined below is based on a normal turn-around time and several stated assumptions. TRC will provide additional support, as needed,to meet the City's schedule expectations. ■ Assumed Selection: March 3,2014 ■ Assumed Notice to Proceed: March 17,2014 Task 1 Develop a Conceptual Site Model-Tentative Completion May 23, 2014 TRC can develop a CSM Report within 10 weeks of notice to proceed(NTP)assuming: ■ Gas and groundwater samples can be obtained within two weeks of NTP. ■ Laboratory analyses will require two weeks on normal turnaround. ■ City review will require one week. ■ Development of the final CSM report will require one week. Task 2 Perform an Assessment of Corrective Measures -Tentative Completion July 3, 2014 TRC anticipates developing an Assessment of Corrective Measures within 6 weeks after finalizing the CSM Report assuming: ■ The selected alternatives are modifications to the existing LFG system and MNA. ■ One week for City's review. ■ One week to develop final Assessment of Corrective Measures. Task 3 Develop a Selection of Remedy Report-Tentative Completion August 8, 2014 TUC will immediately begin preparation of the Selection of Remedy Report upon completion of the Assessment of Corrective Measures. Unknowns for the scheduling include availability of MDEQ representatives for negotiations. TRC recommends confirming MDEQ approval prior to substantial development of the Selection of Remedy Report. Task 4 Implementation of Corrective Action-Dependent upon contractor availability Due to the unknown results of the CSM Report and Assessment of Corrective Measures, a representative completion date for implementation is difficult to predict. MNA may encompass several years. It is expected that addition of wells and enhancements of the LFG system can be achieved in a matter of several months.

An extensive plume of CVOCs migrated in groundwater over 1 mile from the dense non-aqueous phase liquid (DNAPL)source zones beneath the industrial waste landfill in fractured limestone bedrock, impacting residential drinking water wells. TRC provided consulting services that included landfill closure, optimizing a groundwater remediation system designed by others, and performing a study that concluded in replacing a pump-and-treat system with MNA. ■ TRC developed a 3-dimensional contaminant transport model and a groundwater flow model to simulate the conditions associated with the original system to more effectively capture the VOC plume and to reduce the overall time and cost of the groundwater cleanup,thereby demonstrating the capabilities and limitations of pump-and-treat technology in the DNAPL/fractured bedrock setting at this site. ■ TRC also evaluated alternative measures and prepared detailed design documents for installing new extraction wells near the landfill source to supplement the original pump-and-treat system. ■ TRC served as general contractor for construction and startup of the system improvements, which began operation in 2001. TRC has provided on-site personnel at the landfill sites for operation,maintenance, and monitoring(OM&M) from the original pump-and-treat system startup in 1996 to the present. ■ TRC performed modeling and monitoring that showed the conventional pump-and-treat remedy would not achieve the required cleanup standards. ■ TRC recommended, and the United States Environmental Protection Agency(USEPA) and Wisconsin Department of Natural Resources(WDNR)subsequently approved,performing a 2-year MNA demonstration project at the site. This MNA demonstration project has been completed,and TRC expects an amendment for the site to utilize MNA as the long-term remedy for the site. ■ Client benefits include a savings of$9 million during the Remedial Design/Remedial Action (RD/RA)phases due to reductions and clarifications negotiated by TRC, landfill closure completed on budget and on schedule, and transition away from the pump-and-treat system saved the client at least$10 million in OM&M costs for an ineffective technology. Chlorinated Solvent Impacted Site-Town of Madison, Wisconsin Chlorinated solvents (perchloroethylene [PCE])had been detected over a large area in a major thoroughfare of the city,but the source of the contaminants could not be ascertained. Of immediate concern were possible impacts to businesses and residences, and the possible contamination of drinking wells. The WDNR contracted with TRC to investigate the study area,locate the PCE source, and evaluate remedial alternatives for the study area using information obtained at each stage of the investigation. The site involves multiple government agencies,which presents additional challenges to moving the investigation and remedial action forward in a timely manner. TRC performed a study of the historical background information, performed subsurface explorations identifying hotspots, and observed a correlation between hotspot locations and transport in a compromised sanitary sewer. TRC performed additional investigation to sufficiently understand the extent of groundwater impacts at the site to allow the site to progress to remediation. TRC reviewed remedial alternatives for the site and recommended enhanced bioremediation via injection of a carbon source to the aquifer near the source area. TRC performed a pilot test injection to further evaluate the February 20, 2014 5 \\NTAPO-tcIADISON\MSN-VOL6\-\WPMSN\PJT2\214122\9990\P21 41 229 9 9 0-OOI.DOCX 1214122.9990 C51y vj Bozeman enhanced bioremediation alternative. Ongoing performance monitoring shows the pilot injection has enhanced reducing conditions and the reductive dechlorination of PCE in the source area, and that the reducing conditions are propagating outward from the injection location.

An management oversight for the landfill closure. extensive plume with primarily TCE,TCA,and other chlorinated VOCs migrated in groundwater over 1 mile from the DNAPL source zones beneath the industrial waste landfill in fractured limestone bedrock,impacting residential drinking water wells. TRC Solutions Landfill Closure TRC prepared the workplans and final design,and provided construction management services for closure of the industrial waste landfill in 1996. Primary elements of closure construction(28 acres)included the abandonment of wells;the disposal of numerous compressed gas cylinders;the installation of a passive gas vent system;and the installation of a composite cover system consisting of compacted clay and a geomembrane,a drainage layer,a cover soil layer, and a vegetated topsoil layer. Optimization of Groundwater Remediation System TRC then optimized a groundwater remediation system that had been designed by Using modeling,TRC Was able to optimize the another consultant. Improvements were needed to attempt to more effectively capture effectiveness of the the VOC plume and to reduce the overall time and cost of the groundwater cleanup. original ptanp-and-treat TRC developed a 3-dimensional contaminant transport model and a groundwater flow model to simulate the conditions associated with the original system to more effectively capture the VOC plume and to reduce the overall time and cost of the groundwater Project Location: cleanup,thereby demonstrating the capabilities and limitations of pump-and-treat Manitowoc County, technology in the DNAPL/fractured bedrock setting at this site..

Pump-and-Treat System Shutdown In 2005, after operating the pump-and-treat system for the minimum required 7-year This was one of the first period specified in the ROD, the groundwater monitoring data clearly indicated that the chlorinated solvent sites conventional pump-and-treat remedy selected by the USEPA was not performing as in the State of Wisconsin expected, or as necessary to achieve the required cleanup standards. TRC performed to be approved for extensive geophysical testing;conducted groundwater modeling and projections of evaluation of MNA as a pump-and-treat effectiveness;and developed a new conceptual site model that long-term remedy. recognized the presence of substantial DNAPL source material in the fractured bedrock beneath the landfill. Our detailed technical assessment concluded that continued implementation of the pump-and-treat remedy would have limited effect on the overall plume and time-to-achieve standards. Therefore,TRC recommended,and the USEPA and WDNR subsequently approved,performing a 2-year MNA demonstration project at the site. This MNA demonstration project has been completed,and we expect a ROD amendment for the site to utilize MNA as the long-term remedy for the site.

Natural Resources, Town of Madison Site Project Challenges Chlorinated solvents(perchloroethylene[PCE])had been detected over a large area, E including monitoring wells in the Town of Madison,but the source of the contaminants tom + could not be ascertained. Of immediate concern were possible impacts to businesses and residences in this busy corridor in the vicinity of Fish Hatchery and Badger Roads,and the possible contamination of drinking wells. The Wisconsin Department of Natural Resources(WDNR)asked TRC to investigate the study area,locate the PCE source,and evaluate remedial alternatives for the study area using information obtained at each ;: . stage of the investigation. The site also involves multiple government agencies,which presents additional Jn— challenges to moving the investigation and remedial action forward in a timely manner. The site is located in a TRC Solutions busy corridor involving businesses and private residences. Review of Historical Background Information As a first step in locating the source of the PCE,TRC conducted a thorough review of the history of the study area to identify potential sources and guide the placement of soil borings. Identification of Contamination Source TRC identified chlorinated volatile organic compounds(CVOCs) from an undetermined source in the groundwater in the surrounding area in the city of Madison. Investigations at five individual sites(City of Madison Refueling Facility,County Highway Department garage, a light industrial manufacturer,a gas station,and a linen supply company revealed widespread CVOC impacts in the area,and at least two "hotspots." Delineation of Hotspots Both hotspots are close to a sanitary sewer that serves the businesses and residences of Project Location: the area. TRC's investigation results suggested that solvents were discharged into the Wisconsin sanitary sewer, and that the solvents subsequently leaked from the sanitary sewer at Project Award: several locations where the integrity of the 50-year-old sewer had become compromised. $333,600+ TRC coordinated a video inspection of the sanitary sewer and identified a low spot in the Completion Date: sanitary sewer where CVOCs may have accumulated and subsequently been discharged Ongoing to the environment. RCyou can rely on PROJECT PROFILE 1 Confirmation of Extent of Impacts TRC successfully obtained City,Town,and County approvals to drill in high-traffic rights-of-way. Drilling was performed in soil and bedrock to confirm the extent of impacts in the source areas and to delineate the extent of impacts to the north and west. The extent of groundwater impacts is sufficiently understood at the site to allow the site to progress to remediation. The heart of the plume is located beneath a major city thoroughfare,and access is extremely difficult. Implementation of Enhanced Bioremediation TRC reviewed remedial alternatives for the site and recommended enhanced bioremediation via injection of a carbon source to the aquifer near the source area. TRC performed a pilot test injection to further evaluate the enhanced bioremediation alternative. Ongoing performance monitoring shows the pilot injection has enhanced reducing conditions and the reductive dechlorination of PCE in the source area,and that the reducing conditions are propagating outward from the injection location. Client Benefits Enhanced bioremediation through reductive dechlorination of the PCE is proving to be effective, and additional injections are anticipated to further enhance bioremediation at the site. 2 rMTRC Results you can rely on t_ PROJECT PROFILE Remedial Investigation/Feasibility Study Remedial Design/Remedial Action for NPL Site - Algoma Municipal Landfill Project Challenges In 1969,the City of Algoma leased property from a local realty company and began t operation of a sanitary landfill. The landfill has no liner,and is underlain by a sand and gravel aquifer. Wastes disposed at the site included typical municipal refuse and manufacturing wastes,such as paints,paint thinner,lacquer,lacquer thinner,varnish, glue wastes,and asbestos-containing kalo dust. When the landfill stopped accepting waste and was covered and closed according to state regulations in 1983,it encompassed approximately 9 acres and contained approximately 200,000 cubic yards of waste. The Algoma site was included on the National Priority List(NPL)because of contaminated groundwater in the sand and in the gravel aquifer. TRC provided Consent Order negotiation assistance,preparation of the RI/FS work plan, implementation of the RI/FS,preparation of the Endangerment Assessment report, preparation of comments on the USEPA Proposed Plan,and negotiations through the ROD,the Consent Decree,and the RD/RA Scope of Work. Throughout the project,TRC worked with USEPA Region 5,the WDNR, and the PRP's legal counsel to develop innovative ways to streamline the CERCLA process. TRC Solutions Consent Order Negotiation Provided regulatory and technical assistance during negotiation of the Consent Order and Scope of Work with the USEPA and state in cooperation with the PRP's attorney. Preparation of R11FS Work plan Prepared the RI/FS Work plan,and assisted in related negotiations with the regulatory agencies. Project Location: Algoma, Wisconsin Streamlining of the R11FS Project Award: Streamlined the RI/FS by developing orderly,no-frills procedures to meet the essential $3,500,000+ requirements for an RI/FS under CERCLA and the NCP while minimizing unnecessary Completion Date: tasks often routinely specified by regulatory agencies. Throughout the RI/FS, efforts by 7993;Ongoing Groundwater TRC to streamline the process allowed the work to progress steadily toward completion Monitoring with more emphasis on technical issues and less on the form and format of the transactions (paperwork). 1 PROJECT PROFILE TRC services included; Partial Work plan Approvals —Consent order Performed field investigations that followed a well-planned,well-organized schedule negotiation that allowed the fieldwork to move steadily and efficiently toward completion.

Endangerment Assessment Report Used the results of the RI to complete an endangerment assessment to characterize site risks. Comments on Proposed Plan During the public comment period following completion of the RI/FS,prepared comments on the USEPA's Proposed Plan in cooperation with the PRP group's attorney and submitted to the USEPA on behalf of the PRPs. Focused Feasibility Study Report Successfully streamlined the FS phase through significant reduction in the number, scope,and format of FS submittals. Met the requirement of the interim report by preparing an Alternatives Array Document(AAD). Obtained USEPA approval to eliminate the various interim review reports in favor of a public review draft focused feasibility study report. To prepare the focused FS,a short section titled Comparative Analysis of Alternatives was simply added to the AAD which had been previously submitted to the regulatory agencies. In the fall of 1991,TRC was retained by the PRPs to continue with the remedial design/remedial action phase of the project. The RD/RA activities include implementation of a groundwater monitoring program,landfill cover design and construction management,landfill gas migration monitoring and control,and post- closure maintenance. In the ROD,the decision as to whether a direct groundwater 2 C�,!TRC Results YOU can rely or, L. PROJECT PROFILE remedy will be required(i.e.,groundwater pump and treat)was delayed. This decision will be dependent on an assessment of the groundwater monitoring data before and after landfill cap construction. A 5-year groundwater assessment report will be prepared to statistically evaluate the attenuation of constituents of concern over time and will form the basis for deciding whether a direct groundwater remedy will ultimately be required at the site. Because TRC focused on a practical remedial alternative early in the RI phase of the project,minimal pre-design activities have been required at the Algoma site. TRC completed the RD/RA activities on an accelerated schedule,which avoided project costs associated with delays and extended schedules. Prior to entry of the Consent Decree in March 1992,TRC prepared a Pre-Design Work plan and the Draft RD/RA Work plan. In the 18 months following entry of the Consent Decree,TRC has completed the following RD/RA activities,including initiation of construction: Pre-Design Investigation A test pit investigation was conducted to characterize the waste in two adjacent disposal areas to determine the appropriate cover design.Given the results,Algoma selected a clay cover for the northern area and a soil cover for the southern area as recommended by TRC. Additionally,as recommended by TRC,no further action was required for a third disposal area for animal carcasses. With TRC's assistance,an Explanation of Significant Change-Difference(ESD)was completed and the Scope of Work(SOW)was revised accordingly. RD/RA Workplan TRC prepared the final RD/RA Work plan incorporating agency comments and revisions to address the selected remedies for the additional disposal areas. Remedial Design TRC prepared the Preliminary Design Plan and,considering its completeness, the USEPA and the WDNR agreed to eliminate the 95 percent design submittal, allowing TRC to subsequently prepare and submit the Final Design Plan. The remedial design included a general soil cover for one disposal area and a NR 504.07 clay cover with passive gas venting for two disposal areas.The design also included waste consolidation, gas monitoring probes,surface water drainage facilities,sediment controls,and fencing. In addition,the following reports were prepared: • Operation and Maintenance(O&M)Plan • Construction Quality Assurance Plan • Construction Health and Safety Plan • Construction Cost Estimate 3 PROJECT PROFILE • O&M Cost Estimate • Project Schedule Care was taken in preparation of the O&M Plan to minimize the owner's long-term costs. For example,TRC negotiated with the USEPA to revise the requirement for semiannual progress reports to annual progress reports,which would coincide with the annual site inspections. Likewise,monitoring and maintenance schedules were coordinated to minimize the frequency of site visits. The plan was written in a manner to keep O&M activities simple and easy to implement. Clay Borrow Clay that meets the requirements of the WDNR is difficult to find in and around Kewaunee County. TRC conducted a preliminary clay search considering wetland issues and economics. Two potential sites were further evaluated. This evaluation included conducting an archaeological survey(required by the State Historical Society),a wetlands survey,and an endangered species review. Given the soil characterization data and the documented effort to locate a borrow site,TRC negotiated alternative soil acceptance criteria for the clay cover with the WDNR and the USEPA. Ultimately,a borrow source 15 miles from the landfill was selected to minimize owner risk in meeting the revised acceptance criteria. Deed Restrictions and Access Agreements The Algoma Landfill Project included unique property ownership issues. The landfill itself was constructed on leased property,and impacted seven separate property owners due to the fill limits,adjacent fill areas,and remedial activities. TRC assisted in negotiating the acquisition of two parcels and permanent access agreements with deed restrictions for the remaining five properties. Groundwater Monitoring Wells and Sampling Eight new monitoring wells were installed and two rounds of baseline groundwater monitoring were performed on 18 wells and four private wells. Construction Plans and Specifications TRC prepared construction plans and bid specifications using the EJCDC format and solicited bids from 11 contractors. TRC pre-qualified contractors,receiving bid documents based on landfill construction experience and OSHA 1910.120 requirements for hazardous waste/Superfund construction. 4 PROJECT PROFILE Construction Management TRC is representing the owner as the owner's agent in managing construction. As such, TRC conducted the Pre-Bid meeting,has payment authorization,approves change orders,and manages the contract. Construction Documentation Construction was performed during the summer of 1993. TRC provided full-time on-site observation during construction. At times,this involved having two field staff at the site to meet the contractor's construction schedule. During construction,it was determined that the waste extended beyond those identified in the RI and field modifications to the cover system were required to complete closure of the landfill. TRC was responsible for keeping the USEPA and the WDNR informed on the progress of the work and the changing field conditions as they occurred. Following the completion of construction,a construction documentation report was prepared and submitted to regulatory agencies. Client Benefits • Installed bladder pumps,which resulted in a cost saving of$6,000 to$7,000 a year in groundwater sampling costs. • Implemented a groundwater monitoring program,resulting in a reduction in groundwater sampling cost of 75 percent over a 5-year time period. 5 I I � 1 i I I I I i 4 I i I I L PROJECT PROFILE Innovative Approach to Environmental Liability and Risk Reduction through Multi- Media Treatment of VOCs - Automotive Parts Manufacturer Project Challenges This facility has a challenging history,with multiple known and unknown source areas, and the presence of significant chlorinated solvent contamination in soil and groundwater.

TRC Solutions Blending drum TRC was retained by the client to implement the multiple remediation strategies to attachment for achieve site-specific closure levels for soil and groundwater. excavator. 3, ( Client Advocacy,Regulatory Negotiations,and Favorable Cleanup TRC assisted the client in negotiations and filing of a restrictive covenant on the property prior to the transfer of the property to a new owner. TRC was also instrumental in demonstrating that the VOCs present in shallow soil and groundwater did not have the potential to migrate into the underlying bedrock aquifer. This allowed for the establishment of very favorable,yet protective,remedial goals for the shallow soil (essentially site-specific soil saturation levels). TRC also demonstrated that MNA and ng potassium pertnmtgaltate. Soil blendiwith enhanced MNA(in bedrock aquifer)will achieve cleanup objectives in the timeframes established in the USEPA Final Decision(FD). Soil Blending and In Situ Chemical Oxidation (ISCO) TRC and Redox Tech performed soil blending and in situ chemical oxidation (ISCO) using potassium permanganate to oxidize the chlorinated VOCs. In situ soil blending involves using a specialized blending device to mix the soils in place and effectively distribute the chemical amendments throughout the soil medium to treat VOCs. This blending process disrupts the soil fabric,allowing the rotary teeth to blend the reagent(s) Project Location: and the soil into a relatively homogeneous mixture. Since potassium permanganate can Ohio effectively be applied with the soil blending approach, it also enabled TRC to take Project Award: advantage of potassium permanganate's relatively stable reaction kinetics when $650,000 compared to other oxidants,allowing it to persist longer in the subsurface for treatment Completion Date: of subsurface soil and groundwater. Six separate treatment areas,with a total volume of Ongoing 3,600 cubic yards,were treated. Confirmation sampling showed soil concentrations were reduced below RGs with only one treatment. 1 CC2),T R C Results you can rely on PROJECT PROFILE j In Situ Thermal Desorption (ISTD) _ Site conditions inside the building made soil blending coupled with ISCO impractical. Overhead clearance limitations,the need to remove concrete flooring within the plant (two layers in some areas),the potential for impacting the building's structural integrity _ near foundations,and the requirement to achieve soil RGs within 2 years of the FD resulted in the selection of ISTD. TRC implemented ISTD with McMillan-McGee (Calgary—Alberta,Canada)and their Electro Thermal Dynamic Stripping Process(ET- �`` ' ~' DSPTM)methodologies. ET-DSPTM uses electrical heating to increase the temperature of the soil and groundwater by conducting current through the resistive connate water that ISTD extraction well. fills the porosity of the soil. The increase in temperature raises the vapor pressure of VOC contaminants,thus increasing their ability to volatilize and be recovered through conventional soil vapor extraction. ET-DSPTM electrodes were installed in the contaminated zone in a custom design array that allows the use of conventional three-phase power to heat the soil. Vapor extraction wells were located strategically within the contaminated soil. The positioning of the extraction wells relative to the electrodes maximizes heat transfer by convection within the porous soil,thus minimizing heat losses and increasing the uniformity of the temperature distribution. The ISTD design also incorporated additional electrodes Collected vapors were outside the soil treatment area to not only directly heat and treat affected groundwater, treated with steam but also induce a halo of"warmed" soil to enhance the ongoing natural attenuation regenerative carbon beds process. prior to venting to the atmosphere.

Vapor off-gas was treated and discharged to the atmosphere below regulatory permitting thresholds; treated groundwater and condensate were discharged of-site though an !!18 NPDES permit. Because of the contaminant mass present in the subsurface,the treatment system utilized a regenerative carbon system. NAPL was contained and transported off site for fuel blending. Excavation of TPH- affected soil. The ISTD system operated for 14 months and recovered 5,600 lbs of NAPL TCE. Sampling following the 14-month operation period has shown that soil and indoor air RGs were achieved. ' _- Excavation and Off-Site Disposal � w Because ISCO was not a preferred option to treat one source area exhibiting diesel-range total petroleum hydrocarbons (TPH) above the site-specific RGs,and consequently a high oxidant demand,this area was treated by excavation and off-site disposal as a nonhazardous waste. Injection of bacteria and Monitored Natural Attenuation (MNA) nutritional supplements into the bedrock. Using natural attenuation data collected during routine groundwater monitoring,TRC demonstrated that conditions in the lacustrine unit are strongly conductive to reductive dechlorination processes and reduction of chlorinated VOCs. TRC then developed a revised monitoring well network to not only monitor the progress of MNA following source area treatment,but also eliminate existing monitoring wells that were well outside the treatment areas and,therefore,of little strategic value. Assessment reports will be submitted to the USEPA at 5 years and 10 years after the FD documenting the effectiveness of MNA in the lacustrine groundwater to demonstrate the achievement of RGs within 15 years of the FD. Enhanced MNA-Bedrock Groundwater TCE degradation products had historically been detected in groundwater samples from bedrock aquifer wells at relatively low-levels as a result of an inadequate well casing seal at a former production well,which facilitated vertical migration of VOCs from the highly affected shallow subsurface to the bedrock aquifer through the annulus. RGs for the bedrock were set by the USEPA in the FD at the federal maximum contaminant level (MCL). Given the 3-year compliance deadline for achieving cleanup criteria and considering the high oxidant demand of the groundwater,the relatively low levels of VOCs, and the stringent cleanup criteria,TRC selected in situ bioremediation by enhanced anaerobic bioremediation as the preferred corrective action for the bedrock groundwater. Specifically,we developed a blended approach of in situ augmentation of the current microbial population through addition of VOC-degrading bacteria,as well in situ 3 PROJECT PROFILE application of nutritional supplements(e.g.,lactate,sulfate,and yeast) to aggressively treat VOCs within the allotted timeframe. In May 2011, groundwater concentrations were below the RGs in all of the bedrock monitoring wells. TRC has completed the treatment injections,and confirmation monitoring is ongoing. Volatilization to Indoor Air The presence of highly affected soil and groundwater under the main site building resulted in VOC concentrations in indoor air that,under existing conditions,showed long—term risk to facility workers. TRC industrial ventilation experts developed a strategy to modify current conditions to reduce indoor air concentrations to acceptable levels inside the manufacturing facility. Additionally,implementing ISTD to treat soil and groundwater has removed the primary source of VOCs that are volatilizing to indoor air and assisted in achieving the indoor air concentrations protective of workers. Subsequent to the ISTD treatment, VOC concentrations in indoor air have met the RGs,and there is no need for long-term vapor mitigation strategies. Client Benefits The client realized significant benefits over the life of this project,as well as over that of two other confidential projects,as follows: • TRC's remediation design experience and in-house expertise to define the nature and extent of affected media,quantify the site specific risk,and subsequently negotiate RGs above the standard, default criteria was instrumental in determining appropriate technologies to achieve the required remediation goals in the expedited timeframes required by the USEPA Final Decision. • TRC was instrumental in demonstrating that the shallow affected soil and groundwater had limited potential to affect the underlying bedrock aquifer by treating soil to concentrations below site-specific soil saturation levels. • TRC was not only able to assist the client with the design and execution of all of the strategies outlined in the CYII,but also tailor the design approach to utilize each remediation approach to address multiple mediums wherever possible. This synergistic approach reduced the short-term capital costs for implementing additional treatment technologies and long-term monitoring costs for multiple media. • Additionally,TRC and the client partnered together in subcontractor management and execution with ISTD and ISCO vendors with an eye on managing and minimizing remediation costs,while maintaining the technical quality needed to meet the requirements of the USEPA Consent Order and Final Decision. 4 TRC '%.;'Results you can rely on 1 . PROJECTPROFILE Design of a Sub Slab Depressurization System - Industrial Maintenance Facility Project Challenges The vadose zone soils and fill beneath the building slab of the maintenance facility were affected with chlorinated volatile organic compounds(CVOCs)that caused indoor air quality issues,thereby limiting the marketability of the property. Data indicated the presence of CVOC concentrations above state-regulated screening levels inside the building. To address the indoor air issue,the client decided to install a sub slab depressurization(SSDS),utilizing data collected during a delineation assessment by another consultant. Results of the active gas sampling at 26 locations in the 15,000 sq.ft.building indicated that the average radius of influence was 25 feet for the mostly sandy subsurface,based on soil vapor extraction at a depth of 5-9 feet below grade at a vacuum of 60-80 inches of H2O. The client wanted to utilize = the data collected during active gas sampling for a basis of design for an SSDS. However,in `R' = ''' consultation with TRC,it was determined that utilizing existing data would have resulted in affected soils being remediated versus the stated goal of mitigating indoor vapor. The client requested that TRC conduct a pilot test and assist with the design and build of an SSDS in an expedited manner(3 weeks)in order to facilitate a real estate transaction. TRC Solutions Pilot Test TRC conducted a pilot test while concurrently designing and assisting with Pilot Testing to the field installation of the SSDS. The goal of this pilot test was to determine Determine Location for the location and number of suction points for system installation. TRC Systein Installation conducted a connectivity pilot test in order to determine the design radius of vacuum influence that could be imparted in the fill material directly beneath the facility's concrete slab to mitigate vapor intrusion potential into the building. As part of the pilot test,TRC installed one 3-inch diameter suction point just beneath the 8-inch slab to a depth of 6 inches. TRC also installed six vacuum monitoring points along a 30-foot transect at 5-foot intervals. The soils encountered below the building consisted of sandy fill. To determine the area of influence of the suction point,a 43-inch water column Project Location: (WC)vacuum was applied to the suction point while vacuum in the sub-slab Ypsilanti,Michigan monitoring points was measured. Vacuum was measured at 30, 15,and 6 cubic feet-per-minute(CFM)extraction rates,and each flow rate was Project Award: $15,000 maintained for 10 minutes prior to recordingmeasurements to ensure that Completion Date: equilibrium had been reached. Based on the measured radius of vacuum January2074 1 PROJECT PROFILE influence at 30 feet from the suction point at 11 CFM,TRC located 10 suction points to cover the required SSDS area(15,000 sq.ft.) Based on the distribution of the suction points,and due to project time constraints, one leg of the system consisting of five suction points was installed the day after the pilot test data was collected and analyzed. TRC further tested the proposed design by applying a vacuum of 6-inches of WC at 32 CFM to the header pipe connecting five suction points.

Piping from suction points was manifolded together at several locations, and vertical risers connecting the Design for Full-Scale SSDS System manifolded piping to suction fans were routed either through the building or alongside the exterior of the building. Each leg of the system was connected to a Radon Away HS2000E fan capable of 72 cfm at 10 inches of WC. This fan selection factored in a pressure drop of up to 2.3-inches WC at 72 CFM,based on each 3-inch PVC leg having 160 feet of equivalent feet of piping (includes fittings,couples,etc.). Suction fans were on the exterior wall of the building. The suction fan exhaust discharges a minimum of 50 feet from any building opening or air intake. 2 PROJECT PROFILE In order to provide a means to confirm that the I OUTSIDE BUILDING — — — I SSDS is operating properly,a flow switch and + ^1-Dr-1 ,�Iw pressure(vacuum)gauge were included near the I I inlet of each suction fan.

Vacuum was also be measured at each suction point and on the suction side of each fan. Air velocity was also measured at each header pipe entering the fans to confirm air flow rates. The system operated as specified in the TRC design. TRC also prepared an operation and maintenance plan for quarterly and annual maintenance that includes,but is not limited to, inspection of floor and wall penetration sealing and caulking,as well as checking the fan static vacuum and airflow measurements and operational variances.
