His recent experience includes Project Manager and senior technical lead for several pipeline releases and other petroleum spills.Two of these projects, 119 BBL Pipeline Release and Cottonwood Creek Diesel Spill,are summarized in Relevant Project Experience section of this RFP.These projects were included for several reasons.Firstly,they were both conducted under an emergency response scenario where time was of the essence to minimize the effect of the spill,prevent,or eliminate risk to third-party damages,and secondly,to develop a cost effective mitigation and remediation strategy that would lead to site closure. An additional component of the 199 BBL Pipeline Release is that once it was determined that the below-ground infrastructure was going to prevent excavation of all contaminated soil,Mr.Mulholland worked closely with the MDEQ to understand what site-specific data would be required to allow contamination above regulatory screening levels to remain.In this collaborative effort,the DEQ granted closure without additional investigation or remediation. —��- � k The Cottonwood Creek Release was included in the RFP because of its emergency response nature and that the land owner initiated litigation early on in the project. This required that all decisions,even under an emergency response scenario,would be closely scrutinized and had to be legally defendable months or years after actions were taken to protect human health and the environment.The release was closed less than three years after occurring,just as the case was going to trial,which resulted in it being settled out of court.

Approach and Qualifications Approach Phase I:Review Existing Public Response Effort and Develop a Preliminary Conceptual Site Model (CSM) using historic data. Due to unknown constraints at the site,the highest priority will be to review soil gas and ambient air quality data associated with each home on St.Andrews Drive to ensure the initial public response effort prevents direct inhalation of environmental exposures.This process will create a pro-active risk-based approach of providing initial investigation for current ambient air quality within residences. If needed and immediately thereafter,commissioned,sub-slab depressurization systems will be installed according to established criteria.In addition,methane gas will be checked to measure the flammability potential within the substructures to prevent an explosion hazard potential.The systems will be installed and monitored to provide real-time data of operation,if warranted. • L In addition to ensuring the initial public response effort is sufficient to mitigate direct environmental exposures,the existing site data will be used to construct a ( CSM.Information reviewed will include at a minimum: t Environmental and geotechnical boring logs from Landfill as well as any publically available or ascertainable logs from adjacent properties; ( Groundwater quality and quantity data;and • Soil vapor data. ( These data will be used to construct a preliminary CSM with two primary objectives:understand what we know and what we do not know about the site. These will include the various physical,chemical,and biological factors that control the fate and transport of contaminates from the source to receptor(s).Primary deliverable will be a site plan with major project features and relevant cross- sections detailing relevant features and areas requiring additional investigation. CTA understands the sensitivity of the project and will complete it using the utmost care and coordination with the City and land owners in accordance with an agreed upon plan. Phase II:Ground Truth and Closing Data Gaps,Finalize CSM, Develop& Evaluate Remedial/Mitigation Alternatives based on CSM Collect,evaluate,and interpret site-wide data to complete CSM.The CSM will focus on identifying the source of migrating vapors,the migration pathways,and subsurface conditions that encourage preferential flow. Based on the data gathered in developing a CSM,remediation and/or mitigation 19 CITY OF BOZEMAN SANITARY LANDFILL COMPREHENSIVE CORRECTIVE ACTION PLAN :: CTA alternatives will be developed to address,as appropriate: • Sources control; '. • Migration pathways/Receptor exposure;and • Remediation of contaminated media to below appropriate levels. .. At this point,it may be necessary to collect additional data to ground truth what is known about the site as well as close data gaps and fill in the details of what is not known.Using a phased approach,large amounts of broad brush stroke,site-wide WA6 data can be collected quickly and cost effectively using various non-destructive ' geophysical methods.Typical geophysical methods include Electromagnetic Induction (EMI),Capacitively Coupled Resistivity(CCR),Galvanic Contact Resistivity (GCR),and Ground Penetrating Radar(GPR).Geophysical methods are used to determine spatial changes in soil properties as well as identify specific subsurface structures like buried utility corridors.These data,along with basic geochemical groundwater data,often identify subsurface soil and/or groundwater anomalies that tell the story of a source area and/or migration pathways that are well defined or require additional soil coring investigation to better define or ground truth. This process will be conducted in a manner where third-party stakeholders are listened to and comments or concerns can be incorporated into the data collection events when determined to be within the project scope by the City of Bozeman. The advantage of CTA's project team is all of these functions are conducted in- house by project team members.The geotechnical engineer,when collecting field data,understands how it will be used by the Environmental Engineer and CIH to remediate or mitigate risk.This working relationship between team members is intrinsically more beneficial to the project because it saves time and valuable resources,resulting in a streamlined,defensible approach towards characterization and remediation efforts. - - At this stage,the data will be of sufficient quality and quantity to accurately characterize the site,finalize the CSM,and establish an appropriate corrective measure based upon several alternatives. Phase III:Remediation and/or Mitigation Design Implementation • Preliminary Corrective Action (CA) Remediation/Mitigation Alternative Design Report(text,tables,figures and specifications); • Conduct pilot study of remediation/mitigation technology to demonstrate appropriateness for site as well as collect full-scale engineering design parameters(if necessary) • Final Corrective Action Alternative Report(text,tables,figures and specifications); • Project Bidding; • Construction Engineering;and • Post-Construction(record drawings and performance monitoring). The preliminary CA report will include a proposed remediation/mitigation technology.It may be required to conduct a pilot study to demonstrate the 20 r r CITY OF BOZEMAN SANITARY LANDFILL COMPREHENSIVE CORRECTIVE ACTION PLAN CTA t 1 investigation and cleanup for the City of Bozeman at the new public library site.Subsequently,the City of Bozeman expanded the project F to include a study of potentially contaminated soils adjacent to the i r rail corridor.Investigation efforts r - included empty lots,utility corridors, streets,paved driveways,and alleyways.A major component of this project was CTA's C1H working �r closely with DEQ to develop a sound and defensible sampling and analysis plan to confirm the presence or c absence of contamination within the study areas and develop risk-based a working level concentrations using new EPA guidelines.Investigation and remediation was funded through CECRA and the eligible controlled allocation of liability act(CALA). Specific services included: • Public Meetings:CTA assisted the City of Bozeman and the DEQ in complying with public comment about the project by publishing required public comment and notification,providing several community meetings and educational opportunities,as well as completing a public comment and project awareness " seminar for continued community and project support.CTA staff assisted the completion and approval of the project specification documents. • Quality Assurance:CTA staff prepared a DEQ-approved Sampling and Analysis Plan (SAP) providing thorough,detailed,and precise guidance throughout the remedial investigation.Data validation was performed under the direction of CTA's CIH staff prior to final report submission. • Technical Support:CTA staff provided technical support to the City of Bozeman and DEQ throughout the initial phases of the project to establish contamination parameters and project goals,as well as ensuring the parameters were followed and the goals met. Operation and MaintenanSelenium Alternate Source Demonstration for MDEQ Permitted Hazardous Waste Land Treatment Unit(LTU); Billings,MT CTA personnel conducted an alternate source demonstration for selenium in groundwater beneath a Resource Conservation and Recovery Act(RCRA) permitted hazardous waste land treatment unit(LTU).Tim Mulholland,as project manager for an environmental consulting company,conducted an alternate source demonstration to confirm that selenium present in adjacent perennial creek was originating from the Bearpaw Shale formation,not the LTU. 23 r CITY OF BOZEMAN SANITARY LANDFILL COMPREHENSIVE CORRECTIVE ACTION PLAN CTA -EQ-0ION.SIA)N T i a a a + r a a s f 9EOROL><ElN£ACE � ' IN ALLUYIW ' SELENUIIGONOENIRATEO w SEFP ARFA aaAWcptwTpN WY ef g1fTEFER016 SHALE 8YW►CFAVIX 7:�� 2.1Ernm( ! �, GAO IUNBEDRO KLOW !'

Bedrock and alluvium groundwater data were plotted on Stiff diagrams and based on analysis and historic alluvium and bedrock groundwater elevation data,as well as surface water and shallow and deep creek sediments analytical data,a CSM was developed that demonstrated that source of selenium was naturally occurring from weathering bedrock.The regulatory agency agreed with the conclusions. Operation and Maintenance of Hazardous Waste Land Treatment Unit (LTU);Billings,MT This project included annual operation and maintenance of a MDEQ permitted hazardous waste land treatment unit(LTU)where refinery wastes were land-applied and naturally occurring micro-organisms biologically degrade hydrocarbons.Tim Mulholland,as project manager for an environmental consulting company,was responsible for operation,maintenance,and compliance to permit conditions which included semi-annual ground and surface water sampling,annual soil sampling,monitoring soil conditions for optimal waste degradation(soil moisture, nutrients and waste concentrations),detailed record keeping of waste application consistent with permit conditions,and reporting of sampling results in an annual report to MDEQ.In addition to the day to day operation of the LTU,Tim helped negotiate with the MDEQ the use of the LTU for non-refinery wastes from historic pipeline release across central Montana.This allowed the use of the remaining a , capacity of the LTU for non-typical waste disposal at significant cost savings. _ L p. 24 t CITY OF BOZEMAN SANITARY LANDFILL COMPREHENSIVE CORRECTIVE ACTION PLAN CTA kSi• , ,k ' l i- �.
