HomeMy WebLinkAboutRESPONSE - RFP - P818Environmental PROJECTS COMPLETED UNDER THE GENERAL ENVIRONMENTAL SERVICES CONTRACT 2629 Redwing Road, Suite 120, Fort Collins, CO 80526 970-223-5655 -walsh Another advantage WALSH offers to Fort Collins is our understanding and ability to address the unique kinds of environmental problems that municipal governments often require. For example, many firms can perform Phase I environmental site assessments under ASTM standards (developed for commercial real estate transactions), and Phase II studies on "sites" or "properties." However, few companies have near the experience and knowledge in "appropriate level" of investigation for corridor studies or acquisitions, or for assessments for street widening, temporary and permanent easements, strip acquisitions for bikeways, or assessments prior to utility installations, etc. WALSH understands the unique requirements and concerns of a city, resulting from its role as both owner and acquirer of properties that are subject to liability and regulation, and its many roles in planning, development, and regulation. WALSH has demonstrated that it can provide outstanding technical services, and perform pioneering work in environmental assessment and remediation. For example, WALSH did pioneering work in the discovery, characterization, assessment of health risk, and remediation of indoor air impacts arising from chlorinated solvents in ground water. Our work on chlorinated solvents in indoor air at the CDOT Headquarters site in Denver and Glendale (1996-2001) is recognized as the first major project of its kind, and has provided the technical foundation for the approach of all similar, subsequent projects in Colorado and around the country. We view it as our responsibility to go beyond mere completion of assigned tasks, and to guide and assist the City and its staff in diverse, multidisciplinary projects, and to insure coordination and success. We offer as an example our efforts to help City staff obtain Brownfields Pilot Assessment funding from the U.S. EPA. Another example is our efforts to help develop and complete Supplemental Environmental Projects in conjunction with the U.S. EPA, including assessing the environmental impacts of the City's parts washers, and providing a Spill Prevention, Control and Countermeasure (SPCC) Plan seminar for the City.

WALSH clients also include a wide variety of manufacturing, oil, chemical, mining, real estate, banking, law, agricultural, and other businesses. WALSH has developed very positive relationships with Colorado regulatory agencies over the past 17 years. We are highly experienced with the CDPHE's Hazardous Materials and Waste Management Division, Division of Solid Waste, Water Quality Division, the Colorado Water Quality Control Commission, and the UST and AST regulators at the OIS/OPS. We have presented, negotiated, and received approval from Colorado regulators for site assessment approaches and conclusions, waste management and disposal plans, Corrective Action Plans (CAPS), and remediations at hundreds of sites in Colorado. Our experience with Colorado and federal regulatory requirements and processes, WALSH can expedite resolution of Fort Collins' environmental issues. WALSH personnel in Colorado include over 60 environmental scientists and engineers and support staff. Our multidisciplinary, full -service approach has always been to provide state-of-the-art professional service, not only in investigative methods, technical expertise, and solutions, but also in data handling, graphical presentation, and image processing to optimize the value of our findings to our clients. WALSH technical capabilities and those of its subcontractors, and WALSH's facilities provide comprehensive coverage of Fort Collins' requirements and the RFP's Scope of Services. 01122102.IlenterpriselmarkeAproposaidsklfort eollins12001 contma rebid12002 fort col(ins proposal vfinatl.dae Page 3 AmMM 1.B Specific Service Requirements 1.B.1 Environmental Assessment and Investigation a. Perform due diligence assessments (Phase I Environmental Site Assessments in Accordance with ASTM Standards) of property to be acquired by the City, including recommendations regarding the potential liability associated with a property. WALSH has conducted well over 1,000 Phase I Environmental Site Assessments (Phase I ESAs) and Transaction Screens since 1988. WALSH has extensive experience in conducting the unique type of site assessments that the City of Fort Collins and other government agencies often require. WALSH understands how the City of Fort Collins' requirements for ESA information may differ from those of typical commercial real estate transactions for which the ASTM Phase I ESA (ASTM E-1527) and Transaction Screen (ASTM E-1528) standards were developed. For example, city government projects may require acquisitions of numerous properties for transportation corridors (such as WALSH's Phase I ESA of more than 20 properties for the Timberline Avenue Extension). Corridor projects may require assessment of the risks adjoining properties pose for construction on City right-of-ways or utility work. We are leaders in managing corridor Phase I ESAs at low cost, such as our Phase I ESA on 254 properties for the I-270 extension over I-25, which was completed for $53,000 or about $200 per property. WALSH has performed numerous Phase I ESAs on properties that are being donated for open space, and properties that must be acquired for roadways, bikeways, and other local government projects. WALSH is fully experienced in the unique aspects of these transactions, the need to protect public entities from environmental liabilities, and the sensitive nature of many of these transactions to the property owners, neighbors, and other stakeholders. We have successfully balanced our government clients' need for timely Phase I ESA information, and their desire for cooperative relations with property owners. We understand that environmental investigations for public entities have unique aspects, and these require knowledge of City objectives, and sensitivity to property owners' concerns, including environmental issues, tenant concerns, financial aspects of the acquisition, and the affects of any construction. Beginning with a thorough understanding of the City's project needs and objectives, WALSH can efficiently identify the "appropriate level" of Phase I environmental site assessment for all types of properties and circumstances. Section 4.5.3 of ASTM E-1527 states: "Level oflnquiry is variable: not every property will warrant the same level of assessment... the appropriate level of environmental site assessment will be guided by the type of property subject to assessment, the expertise and the risk tolerance of the user [Fort Collins], and the information developed in the course of the inquiry. " Experience, technical expertise, and willingness to exercise professional judgment, have allowed us to efficiently achieve the "appropriate level" of assessment, and to sort out the useful and relevant conclusions and recommendations for government projects. The minimum standards for WALSH ESAs are ASTM Standard Practices E-1527 and E-1528. In addition to the ASTM standard search, WALSH project staff are experienced in the review of agency files, City files, aerial photos, design plans, and Sanborn Fire and other fire insurance maps. We have extensive experience interviewing various local emergency responders including local fire and health department officials as appropriate and applicable. 0122102.I1enterpriselmarketlpmposaldsklfori colliosl1001 contract rebidl1002 fort collins proposal vftnal2.doc Page 4 WaM WALSH is expert at appropriate site inspections, which vary from "drive -by" and "walk -by" to on -site examination. In our 1000+ Phase I ESAs we have found evidence of existing or former USTs and ASTs; vats, buildings, and structures with pipe entrances and vent stacks,; staining of soils; stressed vegetation; storage of wastes; partially buried debris and containers; seeps; pipe outfalls; transformers; sumps; septic fields; ponds; pits; containment structures; odors; recent ground disturbances; floor drains; fill holes; outbuildings; and many others. WALSH's Property Assessment Questionnaire, consistent with ASTM Standard Practices, assures that interviews with owners and occupants consistently cover the important questions, and are recorded accurately. WALSH obtains the owner/tenant dated signature and statement that responses "are true and correct; and to the best of the preparer's actual knowledge, no material facts have been suppressed or misstated." WALSH has been an innovator in presenting complex ESA findings, including compilation of findings in databases and summary tables, depiction of findings in geo-referenced maps, to assist the City in planning and interpretation and enhance the value of our findings for future users. We have extensively applied Geographic Information System (GIS) and image processing software in ESA work. For example, WALSH used image processing of oblique historic air photos to precisely locate the limits of a long - buried waste disposal pond at the former Western Wood Treatment facility in northern Denver, that was impacting the I-25 right-of-way during highway improvement activities. b. Perform Phase HInvestigations associated with and in support of the above property transfer due diligence assessments. WALSH has completed hundreds of Phase II site investigations on a wide range of active and abandoned industrial and commercial properties, UST and AST fuel storage sites, landfills, railroad and highway ROWs, residential areas, and office and retail complexes. We have also conducted many Phase II investigations of properties affected by mining and smelting activities, at former military sites, petroleum production facilities, DOE nuclear sites, and sites under CERCLA, RCRA, and TSCA regulation. WALSH develops Sampling and Analysis Plans (SAPS) that are targeted to the needs of our clients, and meet all appropriate Data Quality Objectives (DQOs). We are experienced in characterization of the nature and extent of a wide variety of contaminants, including petroleum hydrocarbons, toxic metals, chlorinated solvents, PCBs, wood treatment chemicals, radioactive elements, pesticides and other industrial chemicals. We are highly experienced at both subsurface soil and ground water sampling, and at conducting surface soil sampling programs. WALSH has designed and implemented hundreds of ground water sampling and monitoring programs, and soil -gas surveys. WALSH was a leader in Colorado in the use of on -site analysis in environmental investigations, using with both screening techniques and our fully equipped mobile laboratory. We have conducted numerous drum -sampling projects to characterize unknown materials. WALSH is a recognized leader in design and implementation of indoor air studies. WALSH's subsurface studies have included large and small-scale soil -gas sampling investigations. For example, we completed a nearly year long program of soil -gas sampling, with on -site GUMS analysis of soil gas in our mobile laboratory, at the DOE's Rocky Flats site. WALSH has completed soil vapor studies at many UST sites and sites where chlorinated solvents were released. WALSH geologists have completed thousands of boreholes to characterize soil and ground water contamination. We have extensive experience installing and sampling piezometers and monitoring wells, including specialized techniques such as dual -phase (soil vapor and ground water) wells, wells for OI122101.Ilenterpriselmarketlproposaldsklfort collins12001 contract reb02002 fort collins proposal vfinaUdoc Page 5 =Walsh monitoring more than one distinct, hydraulically isolated zone, well clusters, and telescope well construction to prevent contaminant migration. We believe that WALSH is the leading provider of asbestos inspection and sampling services in the state. We have performed large-scale asbestos inspections at the former Fitzsimmons Army Base for the new CU Health Sciences Center, Denver's Currigan Hall and McNichols Arena, the University of Northern Colorado, and many other sites with our staff of approximately 10 full-time asbestos inspectors. This same group also provides lead -based paint inspections using state -of -the art knowledge and equipment. WALSH not only plans and performs these investigations, but also provides recommendations for avoidance of liabilities for acquisition, material management and remediation plans, and support for regulatory approval of the project. WALSH has developed numerous techniques for multi -property investigations to reduce costs and enhance the confidence of conclusions, and the value of the findings to the client. Our site investigation reports have received praise from regulators and clients for their clear presentation of complex findings, and the effective use of graphics, databases, and image processing. c. Provide, on an as -required basis, integrated services for the collection, analysis, and interpretation of environmental samples (air, water, soil, biota, and wastes). WALSH provides comprehensive capabilities to collect and analyze samples from any environmental medium, and to interpret the significance of the data for the City of Fort Collins. With WALSH's in- house capabilities for sampling soils, water, biota, wastes, and indoor air, and the capabilities of our subcontractor Air Resources Specialists, Inc. (ARS) for sampling and monitoring ambient air and air emissions, our team can satisfy all of the City's environmental sampling needs. Our subcontractor, Paragon Analytics, Inc. of Fort Collins, can provide laboratory analyses of a wide variety of contaminants. Paragon is a full -service environmental laboratory, with excellent facilities, instrumentation, capacity, staff qualifications, and quality control. Quality Control. WALSH's staff includes chemists with many years of experience in EPA methods, quality assurance and quality control, and can provide data quality reviews, and oversight and review of subcontracted laboratory data for Fort Collins. Our in-house expertise in laboratory analysis and environmental chemistry provides support to project managers in specification of method proper methods, and accurate interpretations of data. Our team has successfully served the City's needs for the past 5 years on this contract. WALSH also maintains a mobile laboratory for on -site analysis of samples, that can be outfitted with any of the equipment of our in-house laboratory, or other instrumentation, should the need arise. WALSH obtains accurate, representative samples in support of all types of site assessments and investigations. WALSH is experienced in preparing and following Sampling and Analysis Plans (SAPS) to provide the right information, and meet the data quality objectives (DQOs) of its clients' projects. For subsurface soil investigations, the SAP describes the number of borings, type of drilling, method of sample collection, sampling interval, field screening methods, number of QA/QC samples, and depth of drilling. For ground water monitoring wells, the SAP includes the well numbers, location, depth, installation design, development, and the sampling and testing protocols. For field screening, the SAP specifies analytical methods, detection limits, and instrument selection. For laboratory analysis, the SAP specifies the laboratory, number of samples, type of analysis, methods, and DOT regulations. The SAP for each project specifies the appropriate methodology for sampling and specifies decontamination procedures for the sampling equipment. WALSH understands the importance of maintaining detailed sampling records, properly storing and transporting samples, including temperature control, and completing analyses quickly. 01122102. Ilenterpriselmarket Iproposaldsklfort collins12001 contract reb02002 fort collins proposal vfinal2.doc Page 6 -wim Air Sampling and Monitoring. With our subcontractor, Air Resources Specialists, WALSH can provide comprehensive air sampling and monitoring programs to meet any objectives the City may seek. ARS has experience and expertise in ambient air sampling for particulates (PM 10), ozone, emissions sampling and monitoring, characterization of aerosols, and all types sampling and monitoring for compliance with the Clean Air Act, completion of Air Pollution Emission Notices, and other applications. WALSH is also a recognized leader in the sampling of indoor air for chemical contaminants, as well as in characterization of airborne biological hazards such as molds. Water Sampling and Monitoring. WALSH has extensive experience in both ground water and surface water sampling. We have conducted hundreds of sampling programs that have characterized the nature and extent of ground water contamination by the widest variety of contaminants. We have used all types of drilling techniques, and sampling methods to meet project objectives. We are experienced with standard well logging, video logging, natural gamma, and neutron density logging of our well borings. WALSH geologists recently constructed and sampled a 600-foot deep monitor well for an abandoned mine site environmental investigation in New Mexico. We successfully employed innovative, low - volume (no -purge) sampling methods for VOCs at a site in Golden, to improve sample quality and minimize investigation -derived waste. We have used all types of direct -push and traditional drilling methods to obtain ground water samples. We have conducted surface water sampling and monitoring programs at a number of waterways along the Front Range and other areas. Soil Sampling. WALSH offers comprehensive expertise in the sampling of both surface and subsurface soils. For example, we have designed and conducted large-scale residential soil sampling programs at neighborhoods near the Globeville Smelter site in Denver, and around Leadville, Colorado, among others. We are experienced with soil sampling using exploratory borings and test pits. One of WALSH's founders, Jim Walsh, is a Certified Professional Soil Scientist with 25 years of professional experience in all aspects of soil sampling design, soil classification, and the application of geostatistical methods in soil studies. WALSH has characterized the nature and extent of subsurface soil contamination at hundreds of sites, including UST and AST sites, sites with chlorinated solvent, pesticide, PCB and other industrial contaminants, metal, and radionuclide contamination. Biota Sampling. WALSH frequently samples and analyzes terrestrial and aquatic organisms. Our Ecology Group comprises six staff members in Boulder, including a Certified Wildlife Biologist, aquatic toxicologist, river ecologist, Certified Wetlands Specialist, landscape architect, and field technicians. They provides technical support in biological sampling programs for Ecological Risk Assessment; threatened or endangered species surveys; small mammal inventories for city and county rodent management programs; and benthic fish surveys as required in NEPA investigation (following EPA Rapid Bioassessment Protocols), and others. We maintain the equipment necessary for such sampling, including small mammal traps, seine nets, petit ponar dredges, kick nets, and stereoscopes. We have completed a variety of projects involving sampling of biota, including: • NEPA documentation for three metal mining projects, a land application treatment project, and a proposed ski area • Ecological risk assessments of mining facilities • Baseline investigations for numerous oil and gas projects throughout the world • Toxicological investigations of acid mine drainage impacts • Risk Assessment of a defense contracting facility in Utah • Environmental Impact Assessment for a telecommunications cable landing project in California Sampling of Wastes. WALSH provides waste sampling services to help our clients properly handle and dispose of materials in containers such as drum, vats, and tanks, according to standard practices such as 01122102.IlenterpriselmarkeAproposaldsklfort collins12001 contract rebid12001 fort collins proposal vfnall.doc Page 7 -Walsh ASTM E-300-73 and EPA guidelines. For example, at an abandoned warehouse in Denver, WALSH sampled 97 drums of unknown liquids, and managed the disposal and recycling of both hazardous and non -hazardous wastes. WALSH sampled wastes in large diameter, unused sludge digestors for the City of Fort Collins at its Mulberry Treatment Plant. Because the wooden covers of the sludge digestors were decayed and considered unsafe, WALSH safety specialists devised means of suspending workers over the large vats using a crane, cables, and safety harnesses. WALSH scientists employed special sampling devices to obtain depth -profiled samples of the sludge, and laboratory results were interpreted by WALSH staff, leading to classification of the large volumes of sludge as non -hazardous waste. WALSH has extensive experience in the proper characterization of waste soil piles. Our staff have sampled and characterized soils at hundreds of sites for recycling as clean fill, as road base under a Memorandum of Understanding between CDOT and CDPHE, as solid waste for disposal at local landfills, or for disposal as special- or hazardous wastes. d. Design and perform subsurface soil and ground water investigations associated with leaking underground tanks, release of hazardous substances, or other environmental impacts. These services are to include the capability of providing drilling and sample collection, and analytical and laboratory services. WALSH has completed hundreds of investigations of UST and AST sites over the past 13 years, including dozens of investigations as a contractor for Colorado's Leaking Underground Storage Tank Program. Our work for the State Department of Labor and Employment, Oil Inspection Section (now the Division of Oil and Public Safety or OPS) has characterized releases into soil and ground water at sites all around the state. We have provided drilling, sampling and analytical services to the OPS and to numerous private clients at hundreds of such sites. We have been leaders in the use of innovative sampling, field screening, and field analysis methods. WALSH provides comprehensive services for the investigation of releases of all types of hazardous substances, and other environmental impacts. WALSH provides drilling oversight, sampling, chemical analysis, health and safety plans, sampling and analysis plans, data collection, permits, and site -specific safety training. A subsurface study generally includes soil gas sampling and analysis, soil boring installation, soil sampling and analysis, monitor well installation, ground water sampling and analysis, data interpretation, and conclusions as to the potential source(s) of contamination. As needed, the WALSH project manager will meet with the City representative to complete an initial site evaluation plan. WALSH will review all site assessment documents and other environmental information prior to development of a sampling and analysis plan (SAP). The SAP will provide the rationale for sampling and analysis and the selected methodology. The SAP will include description of planned construction and disposal activities, sampling methods, laboratory analysis methods, QA/QC and chain of custody procedures, and a site Health and Safety Plan (HASP). WALSH is highly experienced at using horizontal wells for investigation under buildings. Borehole drilling will be used to sample the subsurface soils and further characterize the extent of impacted soil and ground water. Boreholes provide samples for lithologic, geochemical and geotechnical analyses, and serve to identify locations for monitor well installation. A WALSH geologist will provide on -site supervision of the drilling crew, and will ensure proper sample collection. 01122102.1lenterpriselmarketlproposaldsklfon collms12001 contract rebi&2002 fort rollins proposal vfinal2.doc Page 8 WaM e. Advise the City in matters associated with contaminant transport, hydrogeology, geology, environmental chemistry, and related disciplines needed to assess the potential environmental exposure to hazardous substances releases. WALSH's professional geologists, hydrogeologists, geochemists, organic chemists, and industrial hygienists work together to fully characterize contaminant transport and other issues related to potential environmental impacts from releases of hazardous substances. These services are often provided in relation to litigation, where WALSH conducts modeling and contaminant transport studies to determine responsibilities for environmental contamination. Over 7 years, WALSH was the primary environmental consultant to ASARCO for the California Gulch CERCLA site in Leadville; this project involved extensive contaminant fate and transport studies. Our staff has modeled contaminant pathways in soil, soil vapor, ground water, and surface water. We have employed flow models, and two- and three-dimensional models for projects at sites including Colorado manufacturing and asphalt testing facilities, California oilfields, Nebraska gasoline terminals, Kentucky coal slurry spills, and others. f. Advise the City on matters associated with Superfund, state mandated cleanups, underground storage tank programs, voluntary cleanup program, and other investigative type programs. Prepare Spill Prevention and train employees on SPCCplan procedures. The environmental scientists and regulatory specialists at WALSH assist our clients in complying with local, state, and federal environmental regulations. Topics have included the full range of environmental regulations, including CERCLA and RCRA issues, UST regulations, waste management, OSHA and other safety programs, and numerous other issues. We have also assisted Colorado clients with the state's Voluntary Cleanup and Redevelopment Act (VCRA) program, designing and completing voluntary cleanups at a number of sites. We have experience under the EPA's Brownfelds Program, helping the City of Fort Collins obtain a $250,000 grant, and providing Brownfields site assessment services to Fort Collins, Denver, Aurora, and Lakewood. Because the majority of our work is performed in Colorado, WALSH has worked closely with the regulatory agencies, such as CDPHE and OPS, who oversee many of the environmental issues that the City is likely to encounter. As a result, we have an in-depth understanding of their requirements and review processes. WALSH has obtained CDPHE approval for dozens of corrective actions, corrective measures plans, interim corrective measures plans, disposal plans, and material management plans. g. Advise the City on issues associated with the use and release ofpetroleum fuels, chlorinated solvents, PCBs, metals and other constituents that may represent a threat to human health and the environment. Pollution Prevention. We can assist the city in evaluating environmental and safety concerns related to using hazardous materials in various operations, including vehicle maintenance, physical plants, and the wastewater treatment plant. WALSH staff can identify potential alternatives, and when ongoing waste streams are unavoidable, WALSH can evaluate the situation and make suggestions to minimize waste generation or increase recycling and re -use. We have evaluated and redesigned processes at municipal and industrial wastewater treatment plants to increase efficiencies and reduce waste generation. WALSH has provided consulting services for hazardous and toxic material use and release for the City of Arvada, the Arvada Urban Renewal Authority, the Department of Energy - Rocky Flats Plant; the US Army Corps of Engineers, Rocky Mountain Arsenal; the Colorado Department of Transportation; the Colorado Department of Labor Oil Inspection Section, and Unocal. 01122102.Ilenterpriselmarketlproposaldskffort colllns12001 contract reb02002 fort Collins proposal vfinal2doc Page 9 -Walsh Response to Releases. Through our emergency response contracts with the City of Boulder, Boulder, County, City of Loveland, and several biotechnology companies, we often respond to releases of hazardous materials. These have included spills/releases of pesticides, gasoline, sewage, lubricating oil, solvents, cleaning chemicals, asbestos, biohazards, and many others. We assisted the U.S. government in responding to the recent anthrax exposures by providing an industrial hygienist/chemist who sampled and tested for anthrax in mailrooms in Washington D.C. using a portable analytical instrument. We rapidly determine the nature and extent of the spill, and implement control and cleanup measures. We provide state-of-the-art sampling programs to identify and quantify hazardous constituents. While we understand that the City has a separate contract for emergency response, WALSH is able to provide backup response capabilities if required. Disposal of Wastes. Our staff is able to characterize, manifest, pack and arrange for transportation and disposal of solid, special or hazardous wastes. Disposal has ranged from small quantities of packaged laboratory waste to thousands of tons of contaminated soil. WALSH routinely manages waste disposal from our laboratory and from remediation projects. Major waste types have included petroleum, RCRA hazardous, TSCA, ACM, and PCBs. We assist the client in all waste disposal procedures and in finding appropriate and cost-effective disposal or treatment options. WALSH recycles waste as commercial products whenever economically feasible, thereby saving costs and limiting client liability. 1.B.2 Remedial Technology Selection and Implementation a. Evaluate the impact of environmental releases of hazardous substances or petroleum products on soil and water. During any remediation project, the first step is to evaluate the available data and fill gaps, if necessary. As detailed in Section I.B.1 of this proposal, WALSH is expert at assessing the environmental impact of hazardous substances and petroleum products in soils and ground water. Our expertise includes determination of the nature of the contamination, estimated volume of contaminated material, mobility, persistence, toxicity and degradability of contaminants, current and potential exposure pathways, extent and degree of contamination and relation to water resources, potential and actual receptor populations, and potential health effects. We will utilize this expertise to gather the additional data required by our engineers during the remedial design phase. At CDOrs Headquarters site, WALSH designed and Installed a groundwater remediation system to control solvent DNAPLs. We built a brick equipment building that matched existing buildings. If a risk -based remedial action is contemplated, we are fully capable of conducting the required human health or ecological risk assessments. WALSH routinely conducts risk assessments as an integral part of our assessment and remediation projects. We are able to provide Risk -Based Corrective Action (RBCA) Plans according to ASTM standards, and employ ASTM RBCA software. Risk evaluations projects have included evaluation potential effects on the community; potential impacts to ground water, drinking water, and streams and rivers; appropriate cleanup levels for anticipated land usage; potential air pollution; and on selected projects, impacts to ecological receptors, and standards for non -regulated contaminants. 01122102. 1lenterpriselmarketlproposnldskl(ort collins11001 contract rebid11001 fort collies proposal vftaaUdoc Page 10 b. Determine the technologies that would be applicable to mitigate the concerns caused by release of hazardous substances or petroleum products. For each unique site and circumstance, WALSH evaluates both the technical and economic feasibility of potentially viable remedial technologies, identifies the most cost-effective alternatives, and considers current and future liabilities, as well as schedule requirements. We have experience with all the following technologies for remediation of petroleum products and hazardous substances: • Pump -and -treat remediation of contaminated ground water • Air sparging of soils and ground water • Sparging/vapor extraction of soils and ground water • In -situ bioremediation of soils and ground water • Ex -situ bioremediation of contaminated soil • Vacuum removal of contaminated sludge • Soil washing • Product skimming from ground and surface water • Thermal desorption of contaminated soils • Fixation of lead in soil • Treatment wetlands for contaminated surface and ground water • Building decontamination and demolition • Excavation, transport, and disposal of contaminated soils When needed, our engineers conduct pilot testing or feasibility studies to further refine our recommendations for the most appropriate technologies to use at a specific site. WALSH scientists have conducted feasibility studies for hazardous waste remediation for clients such as the State of Colorado (four CERCLA sites), EPA Region VIII (Clear Creek Superfund Site), Rocky Mountain Arsenal (as a subcontractor), Occidental Petroleum, and for the Globe Smelter CERCLA Site. Alternative technologies were evaluated for effectiveness, timeliness, and cost. On many of these projects, WALSH provided mathematical modeling to predict the effectiveness of remediation scenarios, then conducted treatability studies for both petroleum and hazardous substance remediation. WALSH is also backed by the engineering staff of E&E, who have conducted hundreds of pilot testing projects throughout the country at a wide variety of sites. c. Design, implement, andlor manage environmental remediation projects... including obtaining necessary regulatory agency approvals. WALSH has prepared numerous remedial designs for a broad range of sites and hazardous constituents. Our environmental, civil, geophysical, and geological engineers take the lead in designing effective solutions and systems. WALSH remedial designs specify the type, size, location, removal rate, cleanup limits, and operating costs for recommended remedial alternatives. Major WALSH remedial design and implementation projects include: • On -site disposal of contaminated railroad ballast on South Santa Fe Drive that saved CDOT several million dollars • In -situ bioremediation at several petroleum -contaminated sites Soil vapor extraction/air sparging at four gas processing plants • Installation of sub -slab depressurization systems at 11 apartment buildings and more than 20 residences near CDOT headquarters • Removal of radioactive/mixed wastes and closure of a sludge basin at the DOE Rocky Flats Plant • Remediation and closure of nine sites for the Arvada Urban Renewal Authority 01122102.

WALSH also implements or provides construction management and/or oversight for implementation of our Remedial Action Plans. Our project managers are experienced at managing remediation projects of all sizes, from individual underground storage tanks to bulk fuel terminals and airports containing hundreds of tanks and associated piping. In Colorado, we have routinely conducted remediation projects for gas stations and small industrial sites for CDOT, the CDL Oil and Public Safety Section, City and County of Denver, Fitzsimons Redevelopment Authority, University of Colorado Health Sciences Center, Arvada Urban Renewal Authority, Duke Energy, and others IRM 171711 WALSH has extensive experience using horizontal wells to remediate subsurface contamination. This is a plan view of a remediation system employing horizontal wells. d. Prepare necessary reports and submittals, both for the City and any other relevant regulatory or public agency. Reports we regularly submit for regulatory approval include Site Investigations, Material Management Plans, Remedial or Corrective Action Plans, and Closure Plans. We also regularly obtain permits and approvals for remedial action from state and local agencies. This includes obtaining approval of cleanup goals for complex projects from the CDPHE. Permits we have obtained include construction dewatering, land application, and surface water discharge permits under the National Pollutant Discharge Elimination System (NPDES) and state equivalent programs; air pollutant emission notices (APEN) under the Clean Air Act; monitoring well permitting with the State Engineer's office; and leaking storage tank reimbursement applications with the Department of Labor, Oil and Public Safety Section. We are currently conducting a Use Attainability Analysis (UAA) for the U.S. Air Force at F.E. Warren AFB in Cheyenne that addresses water quality in streams impacted by the base. Our use of image -processing, graphical presentation of contaminant data, the presentation of site findings in tabular and database format, and the use of color graphics in our remediation plans have been acknowledged for their innovation and value and have been praised by CDPHE reviewers for their clear presentation of complex information. Our focus is on value to the client, by effectively conveying the findings and objectives of the work to readers. We also strive to create a complete, accurate and accessible archive of information for our client's use, long after the project is complete. e. Excavate and contain hazardous and non -hazardous contaminated materials. WALSH can excavate and contain petroleum and solvent spills or releases, chemical hazards, asbestos, lead, and other types of hazardous materials. WALSH has excavated and handled both hazardous and 01/22f02.11enterpriselmarketlproposaldsklfort collins12001 contract relid12002 fort collins proposal vfinal2.doc Page l Z non -hazardous contamination at numerous sites, from small-scale removals of containers, and drum -sized quantities of contaminated soils, up to large-scale removals involving many rail cars and truckloads. We have performed large-scale removals of PCB and dioxin -contaminated soils, soils with biohazards, solvents, and industrial chemicals. We have also performed numerous emergency -response containments and removals. During the past four years, we have responded to dozens of emergencies in the Boulder area, which have included containment of gasoline, pesticides, sewage, lubricating oils, pool chemicals, and other contaminated waste materials. We have also provided environmental oversight during excavation of former controlled, uncontrolled, and medical landfills. This has involved segregation, containment, and disposal of hazardous and non -hazardous materials. WALSH field personnel are equipped with portable instruments for measuring such hazards as explosive gases, organic vapors, radioactivity, respirable dust and other threats. Field measurements of soil, water and air samples often permit on -site determination of handling methods, and our know-how has reduced the cost of materials handling. WALSH scientists provide support for applications of innovative field measurement technologies including immunoassays, colorimetric methods, and others. We maintain spill response and containment equipment. WALSH has active, as -needed contracts with specialized cleanup contractors for additional emergency response support including vacuum trucks, large booms and skimmers, etc. f. Collect and/or treat contaminated water. WALSH has implemented a large number of ground and surface water treatment programs, using a variety of techniques and approaches. We also have expertise in collection, handling, treatment and disposal of water produced by construction activities. Examples include: • For the City of Sioux City, WALSH conducted extensive ground water treatment following removal of 100 fuel tanks • In Nebraska, we used active bioremediation to treat oil that was seeping into a large detention pond in a petroleum refining/storage facility • In Colombia, we worked with Occidental Petroleum to improve treatment of produced water that was being discharged to the surface during oil production activities • For CDOT, WALSH installed and operated a packed -tower air stripping system to remove pentachlorophenol from surface water accumulating at a construction excavation site Other major water treatment programs have been conducted for Amoco, Arvada Urban Renewal Authority, the CDL Oil and Public Safety Section, and CDOT. WALSH maintains an in-house treatability laboratory. Our senior engineer has more than 10 years experience working with the EPA to determine waste minimization procedures and guidelines for a variety of industries. Factors determining treatment method selection include the contaminant characteristics (e.g. vapor pressure, water solubility, Henry's law constant, concentration, density, viscosity, boiling point, molecular weight, etc.), the properties of the soil (e.g. porosity, water content, organic matter, texture, plasticity, shape and size of pores, temperature, etc.), the site location, and site improvements. Most of these variables require only an informal analysis; however, their consideration is vital to the success of any remedial project. A typical treatment solution for impacted ground water (the general process would be similar for treatment of surface water) would include: 1) aquifer pumping test, 2) design of the ground- water treatment system, 3) installation of the system, 4) system startup, and 5) operation and maintenance of the system. 01122/02.IlenterprlselmarkeAproposaldskffort collias1200l contract rebid12002 fort collins proposal vfinal2.doc Page 13 Walsh g. Provide post -cleanup site assessment, following appropriate site closure activities. WALSH has written hundreds of project closure reports, including a number for CERCLA sites, that have been submitted for agency review and have been approved. On "clean" closures (i.e. in which contaminant levels have been reduced to below regulatory levels), WALSH has prepared post -closure reports when required, and has successfully completed many quarterly ground water monitoring programs as part of closure activities. We manage and maintain remediation systems as long as required to obtain regulatory approval for closure. On closures where hazardous or contaminated materials remain, such as in on -site landfills, we conduct the long-term monitoring required by the CDPHE. We are also adept at creating institutional control programs that allow hazardous materials to remain in place with strict guidelines as to their handling. For example, we have created institutional controls for TCE-contaminated ground water under apartment buildings and single family homes in Denver, for hundreds of asbestos- and lead -containing buildings, and for pesticides under buildings and parking lots at the Mesa County Airport. 1.8.3 Ecological Assessment and Permitting a. Design and conduct assessments of the impact of various programs ... on ecological receptors such as riverine and wetland environment and terrestrial habitats. The WALSH Ecological Assessment Group has performed assessment services for hundreds of projects throughout the U.S., averaging over 40 assessment projects per year. Our six -person team has provided these services to local and county governments, state and federal agencies, private landowners, and various public and private industries. Our staff is comprised of seasoned professionals with backgrounds in wildlife biology, wetland ecology, riparian ecology, botany, environmental planning, environmental law, landscape architecture, water resource management, civil engineering, restoration design, construction cost estimation and construction management. This diverse, in-house experience allows WALSH to draw from a pool of knowledge regarding ecological assessment issues. Thus, our ecological impact assessment process incorporates a broad range of potential receptors as well as incorporating project planning and design parameters. WALSH staff have worked on a complete range of ecological assessment projects in aquatic, wetland, riparian and terrestrial environments. Typical assessment projects include Environmental Assessments, Environmental Impact Statements, wetland delineation and functional analyses, floodplain delineation and modeling, threatened and endangered (T&E) species surveys and habitat characterization, stream and river surveys, floristic inventories, and weed management surveys. Recent examples of these projects include: WALSH designed and implemented a comprehensive ecological restoration plan for a mile -long section of the San Miguel River In Telluride. 01122102.IlenterpriselmarkeAproposaldsklfon collins1200I contract rebid12001 fortcollins proposal vfinal2doc Page 14 ESA, Section 7 consultation assistance for Preble's Meadow Jumping Mouse and CWA Individual 404 Permit assistance, including a "joint" mitigation plan for mouse, riparian and wetland habitat at the Northgate Corporate Village, Colorado Springs Negotiation and planning with client, federal and state agencies to resolve stream and floodplain restoration issues under CWA (Sections 404 and 401), Mine Safety Health Administration and state natural resource damage claims, Martin County Coal Company, Inez, Kentucky c. Advise the City in matters associated with projects to improve, manage, and develop habitat. WALSH personnel have been involved in numerous master planning and design projects to assist clients in preparing landscape and ecological improvements, habitat management programs and master and design plans. These plans typically incorporate ecological issues with parks, recreation and environmental education with tailored project goals and objectives. We have performed natural resource based recreation, habitat creation, restoration, and enhancement projects for both private and public clients, including Broomfield, Longmont, Louisville, Greenwood Village, and Boulder County. Our services include• • Landscape and ecological master planning, concept design, design development, construction documentation, cost estimating, construction observation (QA/QC) • Parks, trails, and recreation facilities design • Environmental interpretation facilities • Presentation graphics and renderings • Stream and riparian corridor master plans • Watershed master plans • Greenway master plans • Habitat conservation plans • Weed management plans Recent project examples of this type include: WALSH stabilized banks, designed recreational amenities, and restored aquatic and riparian habitat along a section of Denver's South Platte River. • Preparation of a Prairie Dog Management Plan for the City of Broomfield • Construction supervision of riverine habitat improvements for the Town of Telluride. This project was awarded Natural Resource Damage Assessment claim funding, as well as GOCO and EPA 319 Non -point Source Pollution grant funding. The project involved riverine habitat improvements, flood control improvements, wetland restoration and creation, treatment wetlands and trails • Master plan recommendations for enhancement of terrestrial and aquatic habitat for the Sandstone Ranch District Park, conducted for the City of Longmont • Preparation of a joint mitigation plan for 60 acres of wetlands, riparian habitat, and Preble's Mouse habitat at Northgate Corporate Village, Colorado Springs • Development and evaluation of alternative approaches to habitat preservation, enhancement, or restoration along South St. Vrain Creek within the Hall Ranch open space parcel for Boulder County An ecological inventory and habitat enhancement plan for a proposed multi -use path adjacent to a riparian corridor for the City of Boulder A wildlife inventory of city open space and a long-term habitat and recreation management plan for the City of Louisville d. Design site revegetation and restoration projects WALSH staff have been designing and building stream, river, wetland, riparian and wildlife habitat projects throughout the United States for over 17 years. In the past six years our staff have designed and 01122102.I1enterpriselmarketlproposaldsklfort colNns11001 contract rebid12001 fortcollins proposal vfina12.doc Page 16 implemented projects in the Arkansas, Blue, Colorado, Eagle, Roaring Fork, San Miguel, South Platte and Yampa River basins in Colorado; the Snake River basin in Wyoming; the Clark Fork and Boulder River basins in Montana; the Gila River basin in Arizona; and the Missouri River basin in Nebraska. Our projects have ranged from basic enhancement and restoration planting plans to complex, excavation/grading/planting creation projects. We approach revegetation and restoration projects utilizing a natural and sustainable design approach. The first step to design is a site feasibility and suitability assessment, followed by baseline data collection regarding "biological benchmarks" and other design criteria. Once the design basis data are gathered, we utilize computer aided drafting and design (CADD) technology and computerized modeling to implement our restoration/mitigation designs. Our designers are also available to assist in the implementation of revegetation and restoration projects. WALSH manages the construction of both our own restoration/mitigation design WALSH designed riparian habitat restoration for a plans (e.g., in a "turn -key" process), as well as river corridor park in Ouray. those prepared by other professionals. All of our design staff have the hands-on construction and implementation knowledge to provide greater practical experience than is typically offered by consulting design firms. Additionally, WALSH teams with a native plant nursery to supply appropriate native plants for our restoration design projects at a discounted cost. Recent revegetation/restoration projects include: • Design and implemention of revegetation plans for 32 miles of stream banks and adjacent riparian habitat in Kentucky • Design of 500 acres of wetlands at a mine tailings Superfund site in Anaconda, Montana • Design of the DOE Wetland Mitigation Bank, Westminster, Colorado (Prior to joining WALSH, Grant Gumee designed and constructed one of the first wetland mitigation banks in Colorado, to compensate for impacts to wetlands during the Rocky Flats cleanup) • Design of the Stanley Lake wetland mitigation and wildlife enhancement project, for the Cities of Westminster, Northglenn and Thornton (conducted by Mr. Gurnee prior to joining WALSH) e. Assessment of Threatened & Endangered Species WALSH staff members have worked on a wide variety of T&E and other species issues. For example, we are currently working with the City of Broomfield to create a prairie dog management plan. We have also done dozens of projects that involve species that may affect projects in and around the City of Fort Collins, including the Preble's Meadow Jumping Mouse, Burrowing Owl, Ute Ladies' Tresses Orchid, and others. We conduct habitat identification and delineation, as well as restoration and mitigation design and implementation. Some of our projects have also included development of long-term site maintenance plans, including ongoing habitat enhancement and weed management. 01/21/02.Ilenterpriselmarketlproposaldsklfort collins1200/ contract rrbid12002 fort collins proposal vftnal2.doc Page 17 Ndsh Recent projects involving T&E species include: • Surveys for T&E plant species at the Henderson and Climax Mines • Surveys for T&E plant species on Boulder County Open Space • Surveys for T&E plant species for the City of Colorado Springs • Vegetation surveys and management plans, including noxious weeds and T&E species, for National Renewable Energy Laboratory sites in Boulder and Jefferson Counties • Intensive vegetation analysis and assessment of Preble's Meadow Jumping Mouse trapping sites along the Colorado Front Range t.8.4 Voluntary Cleanup WALSH has successfully completed a number of remedial actions under Colorado's VCRA (Voluntary Cleanup and Remediation Act) Program. We have helped our clients through the entire VCRA process, including site characterization work to prepare VCRA applications, identification of exposure pathways, identification of cleanup goals, and the more informal risk assessment process under VCRA. WALSH has prepared successful VCRA applications, and completed remedial actions and obtained No Further Action determinations for our clients under VCRA. We have worked with Mark Walker of CDPHE's VCRA Program on several historic mining sites, on potential CERCLA sites, and on cleanup of improperly disposed liquid wastes. WALSH understands what is required for a successful action under Colorado's VCRA Program, and we are familiar with the risks of proceeding with inadequate information. For example, in 1996 the City of Fort Collins sought and received approval of an application to remove coal tar waste from a large gas holder at the former Poudre Valley Gas Plant Site on Willow Street. After implementing the remedial action in accordance with the State -approved plan (at a cost of approximately $500,000), the State declined to provide the City with a No Further Action determination. In fact, after the City's cleanup action, the State actually withdrew their earlier approval of the City's VCRA remedial action application. While WALSH was not involved in preparation of the VCRA application, nor the remedial action, we have been involved in characterization the contamination downgradient of this site in the last several years. The record at this site emphasizes the critical importance of obtaining a thorough understanding of the nature and extent of contamination, and all of the risks associated with both on -site and off -site impacts, prior to undertaking a remedial action under VCRA. The review conducted by the State's VCRA staff, and their approval of the plan, cannot always be relied upon to guarantee a successful remedial action under VCRA. WALSH is currently preparing a VCRA application for a former fluorspar mine in Boulder County, in an area scheduled for Superfund listing under CERCLA. The application, when approved by the State, will allow for remediation of the site outside of CERCLA regulation. WALSH has proposed a VCRA application for a former CERCLA site that may be purchased by the City of Grand Junction for a highway project. WALSH is currently working with the US Fish and Wildlife Service on a former landfill in a sensitive biological environment that may result in a VCRA application. WALSH obtained a No Action Determination under the VCRA for a property that had a release of various liquid wastes. The wastes were characterized and removed, and the remaining contamination was found to be below human health risk standards. WALSH prepared a VCRA application for a former silver -lead -zinc mining district in Pitkin County. The property had about 2 acres of mine waste rock that was eroding into a stream. The application was approved and the site was restored to near -original topography and vegetation. A storm water permit was also applied for as part of the remediation. The site was completely restored within three seasons. 0122102, 1 lenterpriselmarketlproposaldsklfort mllins12001 contract rebid12002 fort collins proposal vftnal2.doc Page 18 WALSH prepared another VCRA application for a former silver mill in San Miguel County. The application allowed for commercial development of the property. 1.8.5 Environmental Auditing a. Design and conduct audits... to assure compliance. b. Develop specific protocols... c. Report WALSH is proficient in a variety of environmental and health and safety audits. We have conducted environmental- and OSHA -compliance audits for RTD, Kerr-McGee Oil Company, Peoples Natural Gas, ConAgra, Western Wellchems (an oilfield service company), and many manufacturers. WALSH recently conducted an environmental compliance audit for Alliant Technologies (formerly Honeywell) for acquisition of over a thousand buildings at three locations in two states. Teamed with Ernst & Young, WALSH conducted an environmental audit of Conoco Corporation's worldwide operations. Typically, an audit program is designed by WALSH and the client to focus on a particular concern. For example, a client wanting to acquire real property may be concerned about liabilities resulting from prior site operations. Other clients may be interested in evaluating their compliance and liability status so that they can upgrade operations and develop long-term environmental plans. The three major categories of audits that we provide are: 1. Environmental Liability Audits. These audits typically focus on owner/operator liabilities and regulatory compliance concerns that could reasonably impact on a decision to acquire, lease, or provide financing for a particular facility or parcel of real property. 2. Process/Operational Compliance Audits. These audits typically do not involve a merger or acquisition, but rather focus on environmental issues associated with the continued operation of a facility. For these audits, regulatory compliance concerns typically become the primary focus, with owner/operator liability issue dealt with as appropriate. 3. Management and Systems Audits. These audits tend to focus on the adequacy of the organizational structure of a particular client's operations. The audit evaluates the resources and commitments made available to achieve environmental compliance, and the level of awareness and training that exists to ensure that responsible personnel have the requisite skill and capability to effectively address environmental issues. Despite the various forms of audit programs, there are common elements that are essential if each program is to be successful. We are careful to integrate these elements into our audit programs: The audit scope and objectives must be defined as early in the project as possible. We normally do this to ensure that pre -audit questionnaires are properly developed and that final reports meet client objectives. The sequence of site -specific audit activities must be determined as quickly as possible, because time constraints and audit objectives can vary widely. Depending on site complexity and client objectives, any or all of three audit phases can he conducted: Phase I: Preliminary identification of problem areas that could pose liability to existing or future owners. This phase typically involves a literature/site file search, interviews, agency contact, and a brief site walk -over visit. No sampling normally is involved in Phase I audit activities. 01122102. Ilenterpriselmarketlproposaldsklfort collins12001 contract rel,02002 fort collins proposal vfmal2.doc Page 19 Phase II: Further detailed investigation as needed to verify/delineate the extent and severity of the problem and to identify potential remedial/mitigative measures and their cost. This typically involves some form of environmental sampling activity. Phase III: Assistance in remedial planning/implementation, if required. Obviously, this site -specific step can become very complex and can extend well beyond the general "audit" goal of problem inventory and preliminary identification of potential solutions. Senior project management is essential. Each audit is managed by a seasoned, qualified, senior -level technical manager who is familiar with the specific type of site/facility under investigation, experienced in hazardous material operations, and thoroughly familiar with applicable environmental compliance regulations. The audit team must be selected to address the environmental issues of concern. The project manager assembles an appropriate team according the size and complexity of the audit, and the mix of skills needed. Audit support functions must be made available to ensure flexibility and quick turnaround. If the need arises for the collection of soil, water, and air samples in Phase II audit programs, WALSH offers 23 years of multimedia sampling experience, and our own in-house analytical laboratory. WALSH also has the capabilities and experience to conduct a full range of occupational health and safety audits and evaluations. We evaluate potential threats to worker or building occupant health and safety and provide recommendations for mitigation and training to avoid threats in the future.

WALSH has the experience and expertise to manage any human and ecological risk assessment projects the City may require. WALSH has successfully provided human health risk assessment on some of the most high -profile contamination issues in Colorado. For example, we provided human health risk assessment of the indoor air impacts from a chlorinated solvent ground water plume in Denver and Glendale, Colorado for CDOT. This risk assessment was the pioneering work on the risks of chlorinated solvents in indoor air from contaminated ground water. The risk assessment was approved by the CDPHE's RCRA Program, and formed the basis for remedial actions at this and other sites around the state and nation. WALSH has demonstrated our ability to provide high quality risk assessment services to its clients using the expertise of our parent company, Ecology & Environment, Inc., and using subcontracted risk assessment professionals. WALSH has worked with E&E's risk assessment professionals on a number of projects, including a human health risk assessment for the EPA and for the City and County of Denver. WALSH has also performed risk assessments for Alliant TechSystems (where a human health risk assessment is forming the basis for closure of a chlorinated solvent site in Denver) and CDOT. 01122102. 1lenterpriselmarkeAproposaldsklfort collins12001 contract rel,02001 fort collins proposal vfinal2.doc Pegg 20 ` a4i WALSH/E&E risk assessors use a step-by-step methodology to compute realistic risks to human health or the environment in a cost-effective manner. The goals of these analyses are to: • Identify and analyze relevant health and environmental issues • Determine exposure probability and exposure consequences • Compute the risk to human health and/or the environment on the realistic basis of likely exposure levels and likely consequences • Identify parameters affecting the risk system that can be addressed by control procedures or remedial activity • Establish practical cleanup goals as a part of a project -wide consideration of the costs and benefits of risk mitigation, including the risk of remedy The risk assessor works with the client to compile and review site -specific data and relevant technical literature and regulations. The compiled data are used in the exposure assessment to ensure development of realistic risk parameters and in the hazard assessment to define the chemicals/contaminants/waste of concern. The subsequent risk characterization combines each exposure probability with its attendant hazards to develop an estimate of the potential risk. In every case, our risk assessor provides a full explanation of the uncertainties associated with the analysis. Depending on client needs, this explanation may be qualitative, semi -quantitative through the use of sensitivity analysis, or quantitative through use of probabilistic techniques. The risk characterization results are used to develop recommendations concerning the need for risk reduction and to specify the required level of mitigation. If several remedial strategies are under consideration, the analysis can be rerun to evaluate the risk reduction efficiency. When combined with an engineering analysis, these findings provide a basis for remediation cost/benefit analysis and evaluations of the risk of remedy: i.e., whether the remedy will result in a high -risk condition for humans or cause an irreversible impact on natural resources. For example, for one energy -sector client, we developed cost estimates for several remediation scenarios —each aimed at a different end land use —before the completion of the full feasibility study. By providing an understanding of the costs implicit in the demands of the regulatory authorities, the cost estimates gave the client and its attorneys the knowledge they needed to successfully negotiate with the agencies. For one federal Superfund site, both the results of a mandated human health risk assessment and strict adherence to regulations dictated the cleanup of contaminated ground water. A simplistic application of the regulatory guidance would have required installation of an expensive ground water collection and treatment system that would have cost the client millions of dollars. We helped the client avoid this expenditure by successfully demonstrating that, while there was a perceived risk at the site, there was little probability for a complete exposure pathway. 1.8.7 Air Permitting, Monitoring, Modeling and Compliance The WALSH team subcontractor for air quality issues is Air Resource Specialists, Inc. (ARS) of Fort Collins. All ARS work for the City of Fort Collins will be under the direction of Mr. Howard Gebhart. Mr. Gebhart was the principal author of the City of Fort Collins Air Quality Management Plan prepared in the 1980s and has since performed other air quality studies on behalf of the City. 01122102.1lenferpriselmarketlproposaldsklfort collins12001 contract reltid12002 fort Collins proposal vfinal2.doc [gage 21 a. Develop and prepare air permits Various City departments operate equipment that are potential sources of air pollution which may be subject to regulatory requirements enforced by the Colorado Air Pollution Control Division (APCD). These potential sources include: emergency power generators; storage and dispensing of gasoline and other motor fuels; degreasing, painting, and other solvent use; storage, handling, and processing of rock and similar materials; and wastewater treatment operations. The Colorado APCD requires permits for certain new and modified air emission sources and the tracking of air emissions through the Air Pollution Emission Notice (APEN) program. In general, APENs are required for both new and existing emission sources unless specifically exempted under APCD regulations. However, APCD rules exempt a large number of smaller emission units and many City operations are expected to be covered under these exemptions. The WALSH/ARS team will assist the City in identifying how permit requirements impact City operations, assist the City in obtaining any required permits, and assist the City in complying with the terms and conditions of any such permits. b. Perform air monitoring, record keeping, and reporting. Prepare routine and special reports of air quality data. This task addresses ongoing compliance for existing City operations. City -owned equipment may be required to monitor and track compliance with permit conditions and other regulatory requirements, as well as periodically provide monitoring and compliance reports to APCD. The WALSH/ARS team can assist the City in identifying applicable monitoring, recordkeeping, and reporting requirements; and in complying with these requirements as necessary. The City also operates certain air monitoring equipment and periodically undertakes special studies and analyses of the collected air quality data to obtain a better understanding of air quality emissions affecting the City and its residents. The WALSH/ARS team can analyze and interpret these data, track long-term changes in air quality conditions, and recommend and/or implement additional air monitoring to benefit the City's air quality management program. c. Advise the City on implications of pending or proposed federal, state, regional, or local air quality laws, regulations, ordinances, and standards. Air quality rules and regulations are constantly changing. Upcoming regulations that may impact City operations include new standards governing maximum achievable control technology (MALT) and updates to new source permitting regulations. The WALSH/ARS team is constantly tracking these changes on behalf of our other clients and will provide similar assistance to the City of Fort Collins on this contract. The City of Fort Collins also has the opportunity to play a more active role in APCD's permit actions for industrial sources impacting the City.

Prepare air hazard assessment regarding release scenarios, zones of impact, identification of impacted receptors. Subtasks d and a have been combined into a single discussion because they both involve activities to comply with Clean Air Act Section 112(r) Risk Management Plans (RMPs). Section 112(r) requires preparation and implementation of RMPs to address the storage and accidental release of hazardous substances. Included with the RMP is a requirement to address the potential hazards of an accidental release through dispersion modeling. Existing City facilities subject to the 112(r) regulations should already have prepared and implemented an RMP. The WALSH/ARS team can assist the City comply with 112(r) regulations including revising existing RMPs and hazard assessment modeling and preparing new RMPs in cases where the City adds new storage of regulated chemicals. In addition, many existing facilities within the City of Fort Collins may have prepared RMPs for their own operations. The City of Fort Collins may be interested in reviewing and assessing any RMPs at local facilities for the purpose of identifying hazardous chemicals on -site, potential release scenarios, and hazard zones. This information may be needed by the City to better prepare the Police Department and other personnel involved with emergency response. The WALSH/ARS team can review and compile data from existing RMPs and ensure that all hazard modeling was prepared on a consistent basis. 01¢2102, I lenterpriselmarketlproposaldsklfon mllins12001 contract r N&2002 fon callirts proposal vf,na12,doc Page 23 1.0 Relevant Project Experience This section describes representative projects for each of the service categories desired by the City. 1.0 1 Assessment and Investigation Projects Oily of Fort Collins, Environmental Services Since 1997, we have completed nearly 100 different projects for the City, successfully completing all on time and on or under budget.

We have a nearly 100% reimbursement rate for OIS-reimbursable projects. Solar Ponds Cleanup, Rocky Flats Environmental Technology Site The solar ponds at Rocky Flats stored and evaporated low-level radioactive liquid wastes containing neutralized acids, sodium nitrate, metal plating solutions, solvents, and sanitary wastes. After several unsuccessful attempts to dispose of the material by other consultatnts, WALSH emptied the final two ponds and transferred the material to an on -site storage facility of RCRA-approved polyethylene holding tanks to await disposal. WALSH constructed a specially modified all -terrain tractor to slurry the solidified salt sludge for vacuum removal, at a fraction of the cost of the robotics systems proposed by other consultants. The project was completed ahead of schedule and under budget. Remediation for Prison Facility Construction The Colorado Department of Corrections planned to build a new prison over an existing landfill and former pistol firing range in Denver. At the pistol range, WALSH stabilized lead -contaminated soils using Portland cement, resulting in reduced disposal costs for the resulting non -hazardous material of $10/ton versus costs of $200/ton if the lead had not been stabilized. The landfill was to be excavated for redisposal elsewhere. WALSH classified waste as hazardous, special, or solid waste. WALSH oversaw the removal, permitting, and disposal of 80,000 cubic yards of waste at a licensed facility under continuous environmental monitoring. Remediation of Former Gasoline Station, Clifton, Colorado WALSH remediated a former gasoline station where approximately 50,000 gallons of gasoline were released to ground water. Free product thickness of up to 10 feet was originally measured in several monitoring wells. WALSH designed, installed, and is operating a dual phase/deep vapor extraction system. A total of 50 vapor extraction wells were installed, and extracted vapors were treated in a thermal oxidizer. In several years, the system had removed 115 tons of hydrocarbon material (approximately 32,000 gallons) from the environment. Remediation ofLNAPL at Pipeline Compressor Stations, Duke Energy Corporation, Fort Lupton At several natural gas pipeline compression facilities which had leaks of natural gas liquids from storage tanks, WALSH designed and installed four horizontal well soil vapor extraction (SVE) systems and SVE/air sparging systems. The systems were designed to remove natural gas light non -aqueous phase liquids (LNAPL) from extensive ground water plumes. Free product was present over areas of over 10,000 square feet at each site. Horizontal wells were used because they were more cost-effective than vertical wells and resulted in minimal site disturbance. Ground Water and Indoor Air Remediation of Chlorinated Solvents, CDOT Materials Testing Laboratory, Glendale, Colorado xeleases occurring over a 15-year time frame from two waste solvent tanks formerly located at the CDOT Material Testing Laboratory (MTL) in Denver resulted in extensive soil and ground water contamination with chlorinated solvents and petroleum products.

Petroleum Remediation, Littleton Glass Contaminated ground water from former USTs has migrated under the Arapco Landfill on South Santa Fe Drive in Denver. WALSH fate and transport modeling predicted that this plume did not migrate more than a few hundred feet into the landfill, thereby limiting human exposure. WALSH negotiated a corrective action plan (CAP) based on quantitative risk assessment and exposure even though contamination levels exceed Remedial Action Categories. ,n and Construction of Treatment area containment system to remove dissolved -phase and vapor contaminants and control off -site migration of ground water and vapors. The WALSH system successfully controlled off -site migration of contaminants and removed 961 pounds of chlorinated solvents during the first year of operation. Also at this site, WALSH pioneered the characterization of indoor impacts from chlorinated volatile organic compounds (VOCs) in ground water. WALSH discovered and verified the presence of chlorinated organic compounds in indoor air over the ground water plume at numerous apartment buildings and single-family homes in 1996. WALSH established methods to measure contaminants in indoor air at the very low concentrations required, and completed the largest indoor air impact characterization study of its kind, including collection of over 2,600 indoor air samples at 531 locations, involving some 1,500 residents. On an urgent basis WALSH designed and installed subslab depressurization systems to remediate buildings and protect the health of residents. UST Investigation and Remediation En ARCO Lower Area One, Butte, Montana WALSH is assisting ARCO in designing and constructing a treatment wetland (series of treatment cells) to mitigate the impact of metals from a historic mining site.

Our 18-person asbestos/lead staff has the education, certifications, and experience to effectively perform any type of asbestos or lead abatement project, including: • Asbestos and lead inspections • Asbestos and lead abatement design and specifications • Project management and oversight • Air monitoring • Operations and maintenance programs • Health and safety plans • Employee exposure monitoring WALSH has conducted asbestos and lead -based paint work on over 600 buildings, from individual residences to McNichols Arena and the Denver Coliseum. For the City of Fort Collins, WALSH completed asbestos and lead -based paint inspections at the Lincoln Center, the Poudre Valley Creamery, the former Total Petroleum site at 741 North College, City Park, at the Depot Building, 906 West Vine, and numerous other locations. In addition, we have provided asbestos services on dozens of buildings at UNC-Greeley, we are currently providing comprehensive asbestos services for the demolition of 50 buildings at the former Fitzsimons Army Medical Center. We have done asbestos work for dormitories and a library at Western State College, and classrooms and a gymnasium at Adams State College. We are the asbestos engineers for the demolition of Currigan Hall, an extremely complicated asbestos management project. WALSH also provides full lead -based paint inspections, design, health and safety oversight, and remediation services. These services are a necessary part of baseline analysis, demolition, repair, and post -demolition disposal projects. Our current project at Fitzsimons is also addressing lead -based paint in 50 buildings. We assess and remediate lead contamination at indoor- and outdoor firing ranges. In the past few years we have provided LBP worker safety and materials management oversight for dozens of construction projects throughout Colorado. Laboratory Packaging of Chemicals WALSH's staff of industrial hygienists and environmental scientists have extensive experience with lab packing and identification/disposal of laboratory chemicals and waste. This may be relevant should the City require assistance in cleaning up clandestine methamphetamine laboratories. Our approach to laboratory packaging ensures efficient, safe disposal of chemicals in accordance with all relevant and applicable regulation. Our team of industrial hygienists initially segregate chemicals into known and unknown substances; known chemicals are then divided by chemical compatibility and packaged for transport under federal Department of Transportation and RCRA hazardous materials. Here, a WALSH technician is disposing of abandoned drums of pesticide. 01122102.IlenterpriselmarkeAproposaldsklfort collinA2001 contraci rebi&2002ton collies proposal vfinal2.doc Page 35 -Walsh regulations. Unknown substances are immediately analyzed and characterized. Once the nature of each substance is established, they are packaged based on chemical compatibility and under DOT/RCRA regulations. Chemicals are disposed of at an appropriate waste disposal facility. Typical projects include: NuTech Manufacturing Corporation. WALSH provided waste management services to a chemical manufacturer in Denver under a RCRA notice of violation issued by CDPHE for illegal storage of hazardous waste. Our team sampled, analyzed, and disposed of 50 unlabeled drums. Chemical Manufacturing Facility. For the termination of all operations of Western Wellchems, Inc., an EPA Small Quantity Generator, WALSH audited the plant, inventoried all laboratory chemicals and samples, designed a disposal plan that included compositing of 2,000 containers of chemicals, arranged for transport and disposal of the organic chemicals to a fuels incinerator, arranged for "lab packing" of materials destined for a hazardous waste incinerator, and provided documentation to protect the client or its assigns from future environmental liability. National Renewable Energy Laboratory. For the Department of Energy at the National Renewable Energy Laboratory, WALSH consulted on the demolition and removal of a former laboratory that was possibly contaminated with hazardous and radioactive wastes. WALSH designed the decommissioning and decontamination, including a contamination screening and identification program to determine whether waste lab equipment or building materials were be hazardous or radioactive wastes, and presented remedial alternatives and cost estimates. Second Opinion Services We frequently provide second opinion services to a variety of clients, including the City of Fort Collins, City and County of Denver, Colorado state agencies CDOT and OIS, the University of Colorado, and the Medical Center of Aurora. Second opinion services are usually completed to assess the consistency of work with professional standards and applicable regulatory guidelines. The second opinion provides recommendations to the client for resolving deficiencies, errors and omissions. Our experience has involved second opinions of: Remediation designs and plans — reviewing design calculations, health and safety issues, contractor selection, drawing completeness and accuracy, and cost estimates Environmental assessment reports for air, soil, ground water, asbestos, and lead -based paint — reviewing thoroughness, data quality, analytical procedures, health and safety, and other issues CAPs for technology selection procedures, pilot test results and analysis, remedial action goals, cost estimation and recommendations Second opinions have ranged from informal verbal feedback to documented written reports. Expert Witness and Public Involvement Services WALSH provides scientific and engineering expert witness services to support remediation plans, real estate transactions, environmental permitting and compliance, and litigation. We have worked with attorneys, clients, and regulators to help negotiate practical, cost-effective settlements. Clients for expert witness/litigation support have included CDOT, ASARCO, Shell, Unocal, and others. WALSH provides a complete range of expert witnesses to support the City. In particular, we have been providing expert witnesses and public meeting presentations at two large hazardous waste sites in Denver and Littleton.

WALSH is offering the services of its Program Manager, Dr. Hal Stuber, at a rate of $90.00/hour, a substantial reduction from both his standard rate ($135.00/hr) and competitive rates for comparable qualifications and expertise. This cost savings on Dr. Stuber's hourly rate continues a commitment WALH made in 1996 to provide a reduction on our Program Manager's rate for the City of Fort Collins. We were able to maintain the same reduced rate, without any incremental raises, during the entire 5 years of our work for the City. WALSH is also offering to provide mobilization of WALSH personnel and equipment from Boulder to Fort Collins at no charge to the City. This is also a continuation of an offer we made to the City for our work under the General Environmental Services Contract from 1997 to the present. Consistent with our commitment to provide timely and efficient service to the City, WALSH opened an office in Fort Collins in June of 2001. WALSH's Fort Collins office is currently staffed with two full-time environmental professionals, adding to our ability to serve the City. We believe these proposed staff and travel cost control measures are consistent with our commitment to provide the City with the best possible technical expertise at the lowest cost. Although the most important cost savings on environmental projects result from innovative solutions and knowledgeable, expert consulting, these cost -saving measures can help the City meet its budgetary goals. WALSH believes these measures will be especially useful to the City on the numerous, smaller -scale projects which we anticipate under the General Environmental Services Contract. The following sections detail our personnel and significant other direct costs. 01122102.Ilenterpriselmarkellproposaldskljart collins12001 conlract reb02002 fon collins proposal vfinal2.doc Page 46 Awe General Labor and Direct Costs And Description of Billing Categories Labor Category Description Levels, Rates and Named Personnel Clerical Support Clerical project support including word I $35 processing, proofreading, formatting II $40 documents, handling communications, etc. III $45 Technical Technical project support including research, I $50 Assistant data gathering, technical editing and document II $55 (Walmsley) management.

Alabama at',Tuscaloosa Cincinnati Refinery, Hooven, Ohio. For Chevron U.S.A. Products B.S., Biology, University of Company, Dr. Freeman led the HHRA for E & E's RCRA facility investiga- Alabama at Tuscaloosa tion and corrective measures study. The objective was to determine if interim removal action was needed for any of the operable units. The HHRA assess- ment team combined historical data with data derived from additional, fo- cused sampling to develop a risk -based priority ranking to determine if interim removal action was needed for any of the operable units. Action levels were set to identify site areas that might pose imminent health threats. Dr. Freeman then defended the Phase II HHRA work plan before the EPA Region 5 project manager and legal staff and, upon agency approval, com- pleted the HHRA using potential receptor populations identified on the basis of identified potential land uses. Under his leadership, the team identified risks posed to future industrial/commercial workers and recreational users by the site as a whole, as well as by its specific solid waste management units. In addition, Dr. Freeman investigated possible inhalation exposure to petro- leum -related constituents released from a free -phase petroleum plume that had migrated off -site. To address possible exposures to residents, including school children, conservative box models were used to model data obtained from surface and downhole flux chamber sampling in a residential area adjacent to the former refinery. The data were modeled as indoor and outdoor exposure point concentrations. Results of the risk assessment (submitted to EPA Region 5 as an interim measure) indicated no excess indoor or outdoor risk even under worst -case conditions, but did indicate that possible surface contamination unrelated to the client's free -phase hydrocarbon plume could be contributing to residential exposure. Dr. Freeman explained the HHRA results to stakeholders, including the Citizens' Advisory Panel, so that com- munity concerns could be addressed. Port Fourchon Petroleum Terminal, Louisiana.

New Bedford Harbor Site, Massachusetts. Dr. Freeman cowrote a hazard evaluation and reviewed the risk assessment regarding environmental exposure to PCBs. He determined allowable daily PCB intake values for systemic toxicological endpoints based on occupational exposures, critically evaluated animal carcinogenicity studies concerning PCB mixtures, and determined a cancer potency factor of 60% chlorine PCB mixtures using a state-of-the-art approach for animal/human data extrapolation. PCB Cleanup Evaluations, West Virginia and Great Lakes. He evaluated PCB cleanup criteria proposed by EPA Region 3 for a chemical plant in West Virginia and met with agency and client representatives to negotiate the cleanup levels. In 1994, he Freeman prepared critical comments on the derivation and use of EPA's PCB potency slope factor in the Great Lakes Initiative. In 1992 and 1996, he prepared critical comments concerning draft toxicant profiles of the Agency for Toxic Substances and Disease Registry (ATSDR) for PCB mixtures. Manufacturing Site, Michigan. Dr. Freeman conducted a risk assessment for a Fortune 500 company. Following state guidelines concerning the restricted use of industrial sites, the risk assessment entailed evaluation of multiple operable units, environmental media, and receptor populations. Drug Risk Assessment. He evaluated the potential risks of the cream formulation in a widely used antitrichonomial application. He derived a potency slope factor for the drug, identified and evaluated the strengths and weaknesses of animal and epidemiological data, and completed a risk assessment regarding the drug's anticipated use. Relational Risk Database for Soil Cleanup, Florida. Dr. Freeman also has developed relational database software for determining soil cleanup levels at sites in Florida; assessed risks from exposure to groundwater containing chlorinated organics; critically evaluated animal carcinogenicity data for 1,1- dichloroethylene (1,1-DCE); and demonstrated that the use of negative carcinogenicity data was inappropriate to determine a cancer potency factor. For one site, he also modeled risks of potential occupational and residential exposure to TCE. For an acid pit site in a suburban community, he assessed potential health effects of exposure on the basis of exposure risk, time of residence, and proximity to the waste site; then compared all know health effects in the population with the known adverse effects of the chemicals of concern.

Dr. Freeman grouped area residences by soil PAH concentration (>10 ppm, 1-10 ppm, <10 ppm) and determined from project records where and for how long each plaintiff had lived within the site. The analysis clearly demonstrated the lack of dose -response for any of the more than 90 self - reported complaints. At trial, the suit was dismissed after the plaintiffs' opening argument. Air Quality Litigation Support, Houston, Texas. He provided expert toxicological support to an E & E client's attorney (King & Spalding) during litigation concerning air quality in the area of a major fuel pipeline fire that had occurred during a major Texas flood. Using data available from post - incident sampling in the incident vicinity and modeled data of air concentra- tions over the course of the four -day event, he showed that any increased cancer or noncancer risk was insignificant. He also showed that ambient exposures in the incident area yielded higher risk estimates than those attrib- utable to the incident itself. In addition, Dr. Freeman identified major mis- characterizations in reports filed by plaintiffs' experts regarding the effects of exposure to benzene, PAHs, and other gasoline/crude oil components. Medical Monitoring Settlements, Kansas City, Missouri. Since 1997, for a major Kansas City law firm, Dr. Freeman has managed E & E's provision of scientific and litigation support on issues related to medical monitoring, carcinogenesis mechanisms, and models used to estimate costs for treating smoking -related illness.

He has focused on state and federal environmental assessment and remediation project management for the past 5 years. His technical expertise includes hydrogeology; ground- and surface -water monitoring; geophysical surveys; solid, hazardous, and radioactive waste site assessment; underground storage tank management; and remediation. KEY PROJECTS ENVIRONMENTAL ASSESSMENT (EA), 1-225 FROM NORTH OF PARKER RD. TO NORTH OF 6TH AVENUE. As a subcontractor to MK Centennial, Mr. Spencer served as a contributing author of the EA for the proposed reconstruction of the highway corridor. The EA was prepared pursuant to the implementing regulations of the National Environmental Policy Act. The purpose of the EA was to determine whether the federally and state funded construction and operation may significantly affect the existing physical and human environments. Environmental studies were performed to minimize the potential environmental, economic and/or social impact. Mitigation was recommended to bring unacceptable impacts to insignificant levels. A Finding of No Significant Impact (FONSI) was attained during early 2000. ENVIRONMENTAL SERVICES FOR THE CITY AND COUNTY OF DENVER. As Program Manager for WALSH's ongoing service contract with the City and County of Denver, Mr. Spencer has served as Project Manager on a wide variety of projects. Recent key projects include: Maintenance Facility Contingency Plan. Mr. Spencer served as program manager for a Contingency Plan (CP) prepared for the City of Denver maintenance facility. The Roslyn Street Facility includes five buildings, the Rocky Mountain Fire Training Academy offices and training grounds, an asphalt batch plant, and a hazardous waste accumulation area. The facility provides maintenance for City and County of Denver equipment, including police and fire vehicles. In addition, vehicle fueling, fire training, and traffic support operations are conducted at the faculty. The facility uses and stores hazardous materials in the various buildings and the hazardous waste storage area. WALSH prepared the CP in compliance with the Resource Conservation and Recycling Act (RCRA) which requires that all large quantity generators of hazardous waste address the procedures to be followed if there is a release of hazardous waste or hazardous constituents. The CP includes agreements with emergency providers, management approval of the CP, and the content requirements of a contingency plan as set out in RCRA. Procedures to be followed are provided in the event of spills, fires, explosions and natural disasters. Individual facility operations are described in detail with each building at the Roslyn Site addressed separately. The contingency plan was designed to minimize hazards to human health and the environment from fires, explosions, or any release of hazardous waste constituents to air, soils, surface waters, or ground water. \\enter pnsdrnarke6pmpnsa1dsk\1.rt toll, nQ W t comract rehid\resuntes\spencecdoc Stanley C. Spencer, REM, CGWP Page 3 meet regulatory deadlines. After several unsuccessful attempts to treat and dispose of the material by others, WALSH was contracted to empty the final two ponds and transfer the material to an on -site interim storage facility. High volume air vacuum tanker trucks were employed to empty the ponds of all liquids and sludge. WALSH designed and constructed a specially modified all terrain tractor to slurry the solidified salt sludges. The system was designed and built at a fraction of the cost of the robotics systems proposed by other consultants. The project was completed ahead of schedule, which saved the client from potential fines totaling hundreds of thousands of dollars. UST INVESTIGATIONS, EPA LEAKING UST TRUST PROGRAM. Mr. Spencer is the consultant program manager for the Colorado Department of Labor and Employment Oil Inspection Section (OIS) preliminary assessment/site investigation program. This program is funded through a cooperative agreement between EPA and OIS. Projects are concerned with field monitoring under CERCLA protocol and include screening site investigations and listing site investigations. He also served as project manager for numerous UST investigations conducted under this Trust program. Projects have included soil - gas surveys, soil and ground -water assessment, identification of responsible parties, risk assessment, corrective action plans, and remedial design and implementation. REMEDIAL INVESTIGATION, ROCKY MOUNTAIN ARSENAL SUPERFUND SITE He served as the site manager for the comprehensive water quality/quantity monitoring program (Task 4) for the U.S. Army remedial investigation (RI) of the Rocky Mountain Arsenal from 1985 through 1988. The RI concerned a combined pesticide and chemical ordnance manufacturing facility. This program involved a combined network of over 1,200 monitor wells and surface water stations. Mr. Spencer was responsible for developing and implementing technical plans, supervising operations, overseeing quality control audits, and compiling data. The program was designed to establish a comprehensive database for use in litigation concerning an area of hydrologic contamination. REMEDIAL ACTION, DOE NATIONAL RENEWABLE ENERGY LABORATORIES Mr. Spencer was project manager for the three year basic ordering agreement for environmental remedial action support at the Department of Energy's National Renewable Energy Resources Laboratory in Golden, Colorado. These projects include development of work plans, sampling and analysis plans to meet regulatory requirements and data quality objectives, risk assessment, and evaluation and implementation of remedial action. Key projects completed under the BOA included assessment and closure of underground storage tanks, assessment and remediation of lead contaminated soils to allow construction of new facilities and conceptual design for decommissioning and decontamination of laboratory facilities in a leased building. SITE EVALUATION, MINING/SMELTING AREAS, PITKIN COUNTY, COLORADO Mr. Spencer was the project manager for the hazardous waste site evaluation incorporated into the Environmental Impact Statement for State Highway 82 Reconstruction in Pitkin County, Colorado under contract to the Colorado Department of Transportation. WALSH evaluated the potential impact of highway construction through former mining/smelting areas with high concentrations of heavy metals on ground and surface waters. HAZARD RANKING SYSTEM EVALUATION, EL PORTAL BARITE MINE, U.S. FOREST SERVICE Mr. Spencer was the principal hydrogeologist for a hazard ranking system (HRS) site investigation on the El Portal Barite Mine, Sierra National Forest. This allowed the U.S. Environmental Protection Agency (EPA) to rank the site according to the HRS for uncontrolled hazardous substance releases. Tasks included mapping the site geology/hydrogeology and surveying the surrounding land use and populations. Water quality was assessed in surface and ground waters. Contaminant pathways and population (human and wildlife) exposures were delineated. Remedial actions were determined and implemented based on the HRS ranking. \\enterprise\markeAproposaldsk\fort collwn 2aot m ,.trWd\resumeser doc Stanley C.
