LLC 13 Specific Service Requirements 1.B.1 Envlronmental 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 conducted under our previous contract period). 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 Walsh personnel use field XRFs, petroleum and solvent field assay kits, and GPS/GIS units on various site assessments. properties for the I-270 extension over 1-25, which was completed for $53,000 or about $200 per property. Walsh has completed numerous Phase I ESAs for the City for Natural Areas expansion and infill purposes, including an assessment of a 23,000 acre portion of the Soapstone Ranch in northern Larimer County, Colorado. We also have performed 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. Walsh provided rapid-tumaround Phase I and II ESAs and building inspections during demolition of 14 buildings in Aspen for redevelopment.

PROFESSIONAL ASSOCIATIONS National Society of Professional Engineers Water Environment Federation National Groundwater Association No Text Walsh Environmental Scientists and Engineers. LLC Beginning with a thorough understanding of the City's project needs and objectives, Walsh can efficiently identify the "appropriate level" of Phase I ESA for all types of properties and circumstances. 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 federal and state agency files, local agency files, aerial photos, building department design plans, and Sanborn 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. 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 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. We are currently developing real-time, web -based site assessment data input and management systems for our assessment work at the University of Colorado's Health Sciences Center in Denver, which will be relocating from Colorado Boulevard to the Fitzsimons Campus. b. Perform Phase H Investigations associated with and in support of the above property transfer due diligence assessments. Walsh has completed extensive site assessment prior to remediation at the Sheridan Redevelopment Area, a brownfields redevelopment along the South Platte River. 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 Rights -of -Ways (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, Department of Energy (DOE) nuclear sites, and sites under CERCLA, RCRA, and TSCA regulation. Walsh typically 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.

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 assessment team combined historical data with data derived from additional, focused 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, completed 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 petroleum -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 hydrocar- bon plume could be contributing to residential exposure. Dr. Freeman explained the HHRA results to stakeholders, including the Citizens' Advisory Panel, so that community concerns could be addressed. ecuingr and vimrnnment, m., �S.er+ Mft� Walsh Environmental Scientists and Engineers. LLC 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 field screening techniques. We have conducted numerous drum - sampling projects to characterize unknown materials, including recent sampling and hazard classification activities in Gulf Coast States in support of the federal governments Hurricane's Katrina and Rita's environmental response. 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 recently completed a complex program of soil -gas sampling in the downtown portion of a city impacted by substantial diesel fuel contamination in soil and ground water in North Dakota. In addition, Walsh has completed soil vapor studies at many leaking UST sites and at 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 monitoring more than one distinct, hydraulically isolated zone, well clusters, and telescope well construction to prevent contaminant migration. Walsh has completed Phase II site investigation activities involving soil sampling, well installation and ground water sampling at a Turf Farm being considered for acquisition by the City. Significant petroleum contamination was discovered on surface soils during the Phase I ESA process. The site was assessed for petroleum, nitrate, and other potential contaminants. Walsh provided technical support and oversight services during subsequent removal/remediation activities of contaminated environmental media. 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 staff for sampling and monitoring ambient air and air emissions, our team can satisfy all of the City's environmental sampling needs. Our primary analytical subcontractor, Paragon Analytics, Inc. (Paragon) of Fort Collins, can provide laboratory analyses of a wide variety of contaminants. Additional laboratory support services can be provided by additional analytical subcontractors Reservoirs Environmental, Inc. (Reservoirs) and Severn Trent Laboratories, Inc. (STL). Paragon and STL are full -service environmental laboratories, with excellent facilities, instrumentation, capacity, staff qualifications, and quality control. Reservoirs will be Walsh's primary subcontractor analytical facility for the analysis of asbestos and lead -based paint related samples. 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 10 years on this contract. 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 DQOs of its clients' projects. Fort Collins Env Services 2007 v8 Page 8 Richard W. Freeman, Ph.D. (Cont.) Port Fourchon Petroleum Terminal, Louisiana. For Chevron Research and Technology Company, Dr. Freeman provided overall direction and QA for E & E's determination of whether risk -based clean-up levels could be developed for a petroleum site that would obviate the need for dredging and sediment disposal in a navigable canal. He developed and defended a voluntary fast -track HHRA for possible exposure to petroleum constituents. The assessment addressed scenarios for direct exposure (dermal contact with sediments and surface water) and indirect exposure (consumption of recreationally caught fish). The results indicated that current sediment and surface water conditions did not pose excess human health risk. The only impact of the produced water releases appeared to be on the benthic community, which currently was shown to be in a recovery phase. The risk assessment was accepted without comment under the Louisiana Department of Environmental Quality's new RECAP guidance for risk -based corrective action. In addition, Dr. Freeman is developing environmental correlations between discrete analyses of PAH concentrations and markers such as TPH and oil and grease, to assist client in determining remediation levels for an adjacent canal that was not part of the risk assessment. Automotive Manufacturing Plant, Bay City, Michigan. For General Motors Corporation Powertrain Group, Dr. Freeman designed and managed E & E's baseline HHRA to support an application to the Michigan Depart- ment of Environmental Quality for continued industrial use of the PCB - contaminated site. Since many worker subpopulations (five were addressed in the risk assessment) worked primarily outside the manufacturing building, he devised a weighting scheme that would not grossly overestimate sitewide risk. He also developed site -specific cleanup criteria for one portion of the site that was relatively pristine and could be sectioned off for uses not covered under the baseline risk assessment. Asphalt Refinery, Mississippi. He developed an alternative cleanup level for total petroleum hydrocarbons in soil. The new level was significantly more cost-effective than the one initially considered, because it was based on class of petroleum compound and used surrogate toxicity values analogous to recently proposed health -based TPH cleanup criteria Refinery Litigation Support, Midwestern US. Dr. Freeman provided QA for E & E's provision of litigation support that enabled a major law firm to successfully defend a midwestern refinery against health and proper ecnl,w, end encnnn mrnl. inc. 2 Richard W.

Dr. Freeman was the DHRS representative on the Pesticide Review Council of the Florida Department of Agriculture and Consumer Services, which advises the State Commissioner on the public health and environmental implications of agricultural pesticide use. He also represented DHRS on the Asbestos Council of the Florida Department of Labor and Employment Security, which reviewed the problem of asbestos in public buildings and proposed legislation for exposure levels, abatement contractor training and certification, and contractor liability issues. Litigation Support For law firms involved in litigation, Dr. Freeman has prepared state-of-the-art toxicological evaluations for situations involving alleged exposure to solvents including TCE, PERC, benzene, and paints, perchlorate; diox- ins/dibenzofurans; PCBs; perfluorooctanoic acid and salts; manganese; and lead. He has prepared evidence -based causation analyses for NHL, leuke- mias, endometriosis, thyroid cancer, hypothyroidism, and multiple myeloma. Midway Village, Daly City, California. Dr. Freeman supported the successful defense of Pacific Gas and Electric Company (PG&E) in a toxic tort lawsuit concerning the Midway Village site, where a California public housing project had been built near a former manufactured gas plant. To address plaintiff self -reported complaints and claims regarding exposure to PAHs in soil, he grouped residences within the project area by soil PAH concentration, determined where and for how long each resident had lived there, then used data from the remedial investigation and public health and environmental evaluation (prepared earlier by E & E) to qualitatively evaluate any possible dose -response relationship between PAH exposure and claimed injuries. 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 ec,jiop and environment. ine_ �e,..rrnw.ero.�.le 5 Richard W. Freeman, Ph.D. (Cont.) 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 attributable to the incident itself. In addition, Dr. Freeman identified major mischaracterizations 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. Investigations of DNA Repair Mechanisms, Kansas City, Missouri. To support other court cases of the Kansas City law firm, he managed E & E's compilation and summation of current scientific information concerning DNA repair mechanisms. He managed a similar data compilation/summation project regarding the consequences of lung stem cell mutation. International Environmental Damage Claims, Kuwait. Dr. Freeman participated in E & E's evaluation of the environmental and public health impacts of the 1990-1991 Iraqi aggression of Kuwait. He designed a methodology to determine increased disease rates caused by the eight -month loss of medical infrastructure that was related to the invasion. He reviewed disease reporting data compiled by the Kuwait Ministry oh Health and established a critical level of disease rate increase. For each identified disease/medical condition, he determined the pre- and postaggression incidence and rate values. The process resulted in the identification of over 30 conditions to provide a basis for the loss valuation analysis. The morbidity data were compiled in a computer database to enable interactive data analysis and graphics prepara- tion. In addition, Dr. Freeman conducted an initial evaluation of the impact of smoke plumes from oil well fires on the health of Kuwait's citizens. Environmental Damage Claims, Saudi Arabia. He had a key role in E & E's public health studies to assess impacts of the Gulf War for the Kingdom of Saudi Arabia.

He has utilized his experience in a broad range of ecological assessment, restoration, master planning and design projects involving terrestrial, aquatic and wetland habitat. He has been involved in the hands-on construction and oversight of many of the ecological restoration projects that he has designed and permitted. Once the projects are completed, Mr. Gurnee is responsible for monitoring and follow-up reporting with Federal, state and municipal agencies to ensure regulatory compliance. As a project manager and senior scientist, Mr. Gurnee has assisted clients throughout the United States. He has participated with clients in the conception, planning, initiation, implementation, management, and completion of large scale, multidisciplinary ecological assessment and restoration projects. Mr. Gurnee has presented papers and assisted in educational programs that further the understanding of ecological restoration and environmental assessment. Mr. Gurnee has also been called upon to provide expert witness testimony and liaison representation in complex regulatory compliance matters. PROJECT EXPERIENCE STREAM & RIVER RESTORATION PROJECTS GYPSUM CREEK FISHERIES ENHANCEMENT, GYPSUM, COLORADO Aquatic habitat improvements along Gypsum Creek included both instream and bankside treatments. Instream treatments served to improve deepwater habitat, create flow separation or concentration zones, increase low flow sinuosity, provide instream cover, improve adult fish habitat, create nursery areas, and enhance spawning opportunities. Bankside treatments for aquatic habitat improvements included creation or enhancement of overhead cover, provision of protective cover and enhancing shading, cooling, and nutrient cycling functions. Bank protection treatments served to correct localized bank instabilities and reduce bank erosion and the potential for sediment deposition downstream. Because the Gypsum Creek corridor was in very good condition initially, the enhancement work was designed following a "don't do more harm than good" philosophy. Only low intensity, low impact treatments were utilized. Only small, rubber -tired construction equipment was allowed onsite and only in specified reaches where established microhabitats would not be Walsh. Environmental Scicntists and Enginccrs. L.LC Air Sampling and Monitoring. With Walsh's air quality specialist, Dr. Arthur Mizzi, we can provide comprehensive air sampling and monitoring programs to meet any objectives the City may seek. We have experience and expertise in ambient air sampling for particulates (PM10), 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. 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. Soil Sampling. Walsh offers comprehensive expertise in the sampling of both surface and subsurface soils. For example, we designed and conducted large-scale residential soil sampling programs at neighborhoods near the Globeville Smelter site in Denver, and around Leadville, Colorado, among others. In addition, Walsh has completed a surface soil sampling project at City Parks and Natural Areas to assess potential impacts of storage and use of chromate, copper, arsenate pressure treated lumber. 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 33+ 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 13 staff members in Boulder, including a Certified Wildlife Biologist, a plant ecologist, restoration ecologists, Professional Wetland Scientists, a fisheries biologist, landscape architects and field technicians. They provide technical support in biological sampling programs for Ecological Risk Assessment; threatened or endangered species surveys; small mammal inventories; floristic inventories; benthic and fish surveys, 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: ■ Stream habitat assessment/ fisheries habitat inventories ■ Ecological risk assessments of mining facilities ■ Baseline investigations for numerous oil and gas projects throughout the world ■ Baseline investigations for numerous Windfarm facilities in the Intermountain West ■ 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 • Threatened and Endangered (T&E) species surveys to support ESA Consultation ■ Resource Management Plans (RMPs) for the Bureau of Land Management (BLM) • County and Municipal natural resource inventories Fort Collins Env Service 2007 v8 Page 9 Grant E.

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 ASTM E-300-73 and EPA guidelines. For example, Walsh staff completed abandoned drum sampling and characterization activities at a City -owned property and provided disposal coordination support and oversight during subsequent over packing and removal of liquid wastes. 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. At the Sheridan Redevelopment Brownfields site, Walsh recently sampled 163 drums and containers of unknown materials. 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 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.

He designed and implemented field investigations to evaluate the biological uptake of metals and fluoride in aquatic and terrestrial food chains and was a principal author of the baseline ecological risk assessments. The work included the collection of water, sediment, invertebrate, fish, vegetation, and small mammal samples for analysis of key chemicals of concern and development of site -specific biological uptake factors. The site - specific data from the aquatic and terrestrial studies helped to significantly reduce potential uncertainties in the quantitative risk assessment. Dr. Mach's work was performed in cooperation with the Shoshone -Bannock Tribe, whose reservation (adjacent to the site) was potentially threatened by the identified contaminants. Additional ARCS Sites, Idaho and Ohio. For the ARCS 9/10 program, he developed guidelines for and conducted ecological risk assessments at Idaho National Engineering and Environmental Laboratory in central Idaho. Under the Region 5 ARCS program, to support the screening ecological risk evaluation for the True Temper Sports site in Geneva, Ohio, he performed screening to identify contaminants of potential concern in soil and sediment, evaluated fate and transport mechanisms, and interpreted the ecological significance of site contamination. Statewide Programs for Alaska DEC, Alaska. Since 1996, under E & E's statewide contamination assessment and water quality contracts with the Alaska Department of Environmental Conservation (Alaska DEC), Dr. Mach has been a member of the E & E team that reviews ecological risk assessments prepared by other contractors for various sites statewide, including coastal sites in southeast Alaska and forested and tundra sites in the state's interior. He is assisting the agency at the Red Dog Mine (one of the world's largest, currently operating lead and zinc mines), where ore concentrate has contaminated extensive areas of freshwater, marine, and terrestrial habitat. The reviews helped ensure that the assessments were scientifically sound and that the conclusions drawn were appropriate and adequately protective of state resources. Dr. Mach also develops ecological risk assessment guidance documents that are used statewide for Alaska's Contaminated Sites Remediation Program. Fort Devens Military Reservation, Leominster, Massachusetts. Dr. Mach supported remedial investigation/feasibility studies for several sites as a team member for E & E's multitask hazardous waste site investigation program for the United States Army Environmental Center. ecolomand rinirnnmrm, ine. .rn.usr er.d+.d w �. eriwm.r. 5 Carl E. Mach, Ph.D. (Cont.) Miami River Aquatic Toxicity Study, Miami, Florida. In 1996, for an E & E client, Dr. Mach evaluated the possible impacts of discharges of ammonia -contaminated groundwater on the sensitive natural resources of southern Florida. He investigated water quality, including levels of ammonia, both upstream and downstream from the client facility, compared the ammonia levels with federal water quality criteria for the protection of aquatic life, and examined possible ecosystem effects of site -related ammonia releases on the Miami River. Railroad Acquisitions and Mergers. For the Federal Surface Transportation Board, Dr. Mach evaluated ecological risk as part of E & E's review of the EIS for acquisition of the Conrail railroad system by CSX and Norfolk Southern in the 23 states east of the Mississippi River. In support of the Union Pacific/Southern Pacific railroad merger, he evaluated ecological risk as part of the review of preliminary mitigation plans for the Truckee River Corridor near Reno, Nevada. The ecological risk evaluation was particularly important, since the river is the water source for both the City of Reno and Pyramid Lake, which supports the federally listed endangered Quiui fish. Lake Trace Metal Studies, Wisconsin. At the University of Minnesota at Minneapolis, Dr. Mach designed, implemented, and interpreted field studies on the biogeochemical cycling of trace metals in an experimentally acidified Wisconsin lake.

LLC g. Advise the City on issues associated with the use and release of petroleum 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. In addition to the services provided to the City of Fort Collins, Walsh has provided consulting services for hazardous and toxic material use and release for the Cities of Arvada, Denver, Loveland and many others, the Arvada Urban Renewal Authority, the Department of Energy - Rocky Flats Plant; the US Army Corps of Engineers, Rocky Mountain Arsenal; CDOT; OPS, and Unocal. Response to Releases. Through our emergency response contracts that we have held or are currently holding with the City of Boulder, Boulder County, City of Loveland, and several biotechnology companies, we often responded 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 have conducted numerous uncontrolled substance releases and drum -sampling projects to characterize unknown materials, including recent sampling and hazard classification activities in Gulf Coast States in support of the federal governments Hurricane's Katrina and Rita's environmental response. 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 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. Walsh has provided the City sampling and hazardous waste disposal coordination support for lead wastes at the Firing Range facility on a continuous basis for the last six years. h.

MIZZI Environmental Attorney —Senior Environmental " " c n It KEY EXPERTISE ✓ Environmental Law ✓ Water Law ✓ Permitting ✓ Compliance Advising ✓ Enforcement Defense ✓ Environmental Toxic Torts ✓ Brownfields ✓ Real Estate Law ✓ Civil Litigation EDUCATION, CERTIFICATIONS, AND SEMINARS J.D., University of Colorado, School of Law, 1997 Ph.D., Applied Mathematics, University of Colorado, 1994 M.S., Applied Mathematics, 1989 M.S., Environmental Science University of Virginia, 1982 B.A. Environmental Science, University of Virginia, 1977 Certified Consulting Meteorologist, American Meteorological Society ADMITTED TO PRACTICE: Colorado, 1997; District of Colorado, 1997; and Tenth Circuit, 2000 EXPERIENCE SUMMARY Mr. Mizzi heads up the Air Quality Practice Group at Walsh Environmental Scientists and Engineers, LLC, E & E's office in Boulder, Colorado, but his expertise also includes water quality and western water rights. Walsh Environmental is a majority owned subsidiary of E & E. Mr. Mizzi has provided regulatory compliance counseling and permitting assistance for a variety of clients throughout the Rocky Mountain west. His air quality expertise includes applied atmospheric modeling, model development, air quality assessments, and permitting under PSD and non -attainment NSR programs His water quality/water rights expertise includes surface and groundwater modeling and development, permitting under the federal and western state clean water acts, and water rights assessments, acquisitions/transfers, alternate points of diversion, well permitting, and substitute supply plans. Mr. Mizzi began his professional career as an associated research scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. NCAR is an internationally reknown atmospheric science research laboratory. His research concentrated on atmospheric model development and analysis. Following a fifteen -year career at NCAR, Mr. Mizzi became an environmental attorney with a practice focusing on air and water quality and water rights. Mr. Mizzi practiced as an environmental attorney for nearly ten years and returned to the technical arena as an environmental consultant. Mr. Mizzi is also a Certified Consulting Meteorologist whose unique combination of technical and legal expertise makes him a highly effective environmental consultant. AIR QUALITY EXPERIENCE LOUISIANA PACIFIC CORPORATION, NSPS REVIEW, ATHENS, GEORGIA Mr. Mizzi assisted the Louisiana Pacific Corporation's environmental counsel in obtaining a Finding of NSPS Non -Applicability for modifications of thermal process equipment. Mr. Mizzi reviewed EPA's Mizzi Paec 2 application of the 40 CFR Part 60, Appendix C statistical procedures to multiple stack tests and found that EPA has misapplied the pooled -variance estimator. Mr. Mizzi showed that EPA's application was incorrect and that when properly applied the modification had not resulted in a statistically significant emission change. CONFIDENTIAL ELECTRIC POWER PRODUCER, LITIGATION SUPPORT, SAN FRANCISCO, CALIFORNIA Mr. Mizzi assisted litigation counsel in settlement negotiations regarding alleged clean air act emissions permit violations by using EPA's ISC dispersion model to assess the regional impacts of the exceedances. Mr. Mizzi used the dispersion modeling results to preparing a quantitative risk assessment of the associated chronic and acute human health risks. Mr. Mizzi then showed that based on the State of California's accepted risk tolerances, the emission exceedances had not create an unacceptable level of risk. COLORADO SPRINGS MUNICIPAL UTILITY, COMPLIANCE COUNSELING, COLORADO SPRINGS, COLORADO Mr. Mizzi provided compliance counseling to the Colorado Springs Municipal Utility related to the NSPS, NSR, and NESHAP programs. That counseling included analyses of whether: (i) various facilities constituted a single stationary source under the NSR and NESHAP programs, (ii) modifications at one of the facility might trigger NSPS, NSR, or NESHAP requirements at one or more of the facilities, and (iii) EPA might regulate one or more of the facilities as support facilities for the other facilities. THE BROE CORPORATION, PERMITTING SUPPORT AND IMPACT ASSESSMENT, DENVER, COLORADO Mr. Mizzi reviewed the applicable state and local regulations governing the siting of a mixed -use office/residential development, proposed by the Broe Company. The proposed development was in the vicinity of an existing municipal waste water treatment facility. Mr. Mizzi used meteorological and TSCREEN modeling analyzes to evaluate the potential impact of odors from the treatment facility on the development. CONFIDENTIAL LANDFILL CLIENT, PERMITTING SUPPORT, GREENWOOD VILLAGE, COLORADO Mr. Mizzi prepared a regulatory review of the clean air act permitting requirements for the expansion of a municipal solid waste landfill. DENVER INTERNATIONAL AIRPORT, COMPLIANCE COUNSELING AND PERMITTING SUPPORT, DENVER, COLORADO Mr. Mizzi provided federal and state clean air act regulatory counseling the Denver International Airport with regard to matters including: (i) the use of operational limitations to obtain "synthetic minor" source status, (ii) the use of emissions banking, (iii) strategies for complying with clean air act's general and transportation conformity requirements, and (iv) preparation of permit applications for airport facilities and its solid waste incinerator. During that representation, (i) Mr. Mizzi successfully negotiated with EPA and the State of Colorado disaggregation of the airport from regulation as a single major source requiring a Title V permit to regulation as three independent minor sources, and (ii) Mr. Mizzi successfully negotiated inclusion of the airports emissions into the SIP to facility compliance of the airport's expansion projects with clean air act conformity requirements. CONFIDENTIAL OIL AND GAS CLIENT, PERMITTING SUPPORT, DENVER, COLORADO Mr. Mizzi prepared a review of EPA's transitionary NSR and NESHAP policies for oil and natural gas operations on tribal lands in western Colorado and Utah. Based on that review, Mr. Mizzi prepared successful letters to EPA requesting findings that the subject oil and gas operations qualified for the EPA's transition policy and certain control technologies qualified as MACT. Mizzi Page 3 EXCEL CORPORATION, LITIGATION SUPPORT, DENVER, COLORADO Mr. Mizzi assisted with preparation of arguments before the Federal District Court for the State of Colorado maintaining that independently owned baseline and peaking power plants should be regulated by EPA and the State of Colorado as separate stationary sources under the federal and state clean air acts. CONFIDENTIAL PRINTING COMPANY CLIENT, GREENWOOD VILLAGE, COLORADO Mr. Mizzi proved regulatory counseling that included: (i) using operational limitations to obtain "synthetic minor" source status, (ii) using alternative chemicals to facilitate compliance with the State of Colorado VOC regulations, (iii) preparing minor source permit and modification applications, (iv) preparing successful requests for findings of NSR non -applicability, and (v) negotiating a SEP to address alleged emission exceedances. HEWLETT PACKARD CORPORATION, LOVELAND, COLORADO Mr. Mizzi prepared clean air act permitting roadmaps for the modification of an existing HAPs emission facility and for the construction of a new HAPs emission facility. Both sources were potential major sources of HAPs. Mr. Mizzi prepared the associated application materials and used operational limitations to obtain synthetic minor source status. GLOBEVILLE CLASS ACTION, DENVER, COLORADO Mr. Mizzi reviewed the physical parameterization in EPA's ISC dispersion model and worked with other environmental consultants to identify the transport mechanism for the peaking of arsenic contamination in the surface soils located several miles from a historical smelter. Mr. Mizzi used correlation analyses to show that the resuspension combined with secondary deposition in the lee of wind field flow obstacles was the likely cause of soil contamination. That work led to a successful settlement on behalf of the residential class. CONFIDENTIAL CLIENT, LITIGATION SUPPORT, MINNEAPOLIS, MINNESOTA Mr. Mizzi used ISC dispersion to show that the historical emissions of arsenic from a pesticide manufacturing facility were unlikely to have caused anomalously high concentrations of arsenic in the neighboring residential surface soils. CONFIDENTIAL CLIENT, LITIGATION SUPPORT, MINNEAPOLIS, MINNESOTA Mr. Mizzi used screening level dispersion modeling based on TSCREEN to show that emission from a soil vapor extraction system were unlikely to create a human health risk or odors at concentrations sufficient to constitute a nuisance. US DEPARTMENT OF JUSTICE, DENVER, COLORADO Mr. Mizzi assisted the US Department of Justice (DOJ) in a clean air act enforcement action against a Montana cardboard paper manufacturer. Mr. Mizzi critically reviewed the emission estimation methods and reporting procedures. He found that the source's practice of updating its emission estimation regression equations with the most recent stack test data had compromised the robustness of the regression equations. Mr. Mizzi then worked with DOJ, EPA, and the source to design an experimental program to re -derive sufficiently robust regression equations. WATER RIGHTS EXPERIENCE CONFIDENTIAL AGRICULTURAL CLIENT, WATER RIGHTS SALE, ACQUISITION, AND PROTECTION, FT. LUPTON, COLORADO Mr. Mizzi assisted with the sale, acquisition, and protection of surface and groundwater diversion rights for a large commercial agricultural operation in eastern Colorado. This work included evaluating: (i) proposed purchase contracts and the reliability/transferability of the associated water rights, (ii) the potential impact of mining on existing water rights, (iii) evaluating the reliability of Mizzi Page 4 alternate points of groundwater diversion, and (iv) facilitating the sale of surface and groundwater rights. CONFIDENTIAL ELECTRIC POWER PRODUCER, WATER RIGHTS ACQUISITION, COLORADO SPRINGS, COLORADO Mr. Mizzi assisted with preparation of water rights transfer and water supply agreements on behalf of a proposed peak power generating facility. This work included evaluation of the adequacy and reliability of the subject water rights. CONFIDENTIAL ELECTRIC POWER PRODUCER, WATER RIGHTS ACQUISITION, COLORADO Mr. Mizzi assisted an electric power producer with gaining a understanding of Colorado water law, developing a water acquisition and supply plan, evaluating the adequacy and reliability of the subject water rights, and developing alternate points of diversion. CONFIDENTIAL ELECTRIC POWER PRODUCER, WATER RIGHTS ACQUISITION, WASHINGTON Mr. Mizzi assisted with an electric power producer with evaluating a water supply agreement and evaluating the adequacy and reliability of the subject water rights. CONFIDENTIAL MOUNTAIN RESIDENTIAL DEVELOPMENT, WATER RIGHTS ACQUISITION, WINTER PARK, COLORADO Mr. Mizzi assisted with the preparation of water rights transfer and water supply agreements on behalf of a proposed mountain residential development. This work included evaluating the adequacy and reliability of: (i) the subject water rights, (ii) the associated groundwater wells, and (iii) the existing substitute supply plan. CONFIDENTIAL MUNICIPAL CLIENT, WATER REUSE AGREEMENT, DENVER, COLORADO Mr. Mizzi evaluated the availability of reuse water based on runoff of trans -continental divide water from a municipally -owned redevelopment project and assisted with a multi -party agreement to allow reuse. CONFIDENTIAL MUNICIPAL CLIENT, WATER RIGHTS DISPUTE, DENVER, COLORADO Mr. Mizzi evaluated the technical and legal merits of a water rights dispute between two municipalities. This work included a review of historical water rights documents and water use information. WATER QUALITY EXPERIENCE MARATHON OIL COMPANY, PRODUCED WATER MANAGEMENT AND PERMITTING, GILLETTE, WYOMING Mr. Mizzi developed and applied a produced water management model to assist Marathon with local and regional planning for coal bed methane (CBM) development in the Powder River Basin. That model simulated Marathon's CBM well water production, its local and regional water distribution systems and water disposal in Marathon's various produced water management facilities, such as infiltration reservoirs, evaporation pits, land application areas, injection wells, and treatment facilities. The model makes ten to fifteen years forecasts of the load on or availability of those facilities, enabling Marathon to optimize its design and management of its produced water disposal system. As part of this ongoing project, Mr. Mizzi also handles all the associated state and federal water quality and water rights permitting, i.e, the WDEQ, WOGCC, WSEO, and USACE permitting. CONFIDENTIAL CLIENT, PROPOSED CHANGE TO DISCHARGE STANDARDS, CHEYENNE, WYOMING Mr. Mizzi successfully assisted a consortium of CBM operators with preparing, analyzing, and presenting comments in WDEQ rulemaking on proposed changes to the discharge standards for CBM produced water. Mizzi Page 5 CONFIDENTIAL CLIENT, NONPOINT SOURCE DISCHARGE, COLORADO SPRINGS, COLORADO Mr. Mizzi successfully assisted the owner of unpaved road located in a national forest in opposing allegations that its maintenance and channeling activities had converted nonpoint source discharges, i.e., stormwater runoff, into an unpermitted point source discharge. CONFIDENTIAL MINING CLIENT, EA PREPARATION, NEVADA Mr. Mizzi used Modflow-Surfact and Hydrus -2D together with statistical analyses of monitoring well data to assist with demonstrating that: (i) the proposed mine expansion would not adversely impact the local/regional groundwater, (ii) an existing leach pad was still dewatering and likely impacting the local groundwater, and (iii) two groundwater basing were hydrologically connected. CONFIDENTIAL BROWNFIELD CLIENT, MONITORED NATURAL ATTENUATION, FLORIDA Mr. Mizzi used Sutra 2D and 3D to assist with demonstrating that natural attenuation was controlling migration of a groundwater contamination plume.

LLC. 182 Remedlal Technology Selection and Implementation a. Evaluate the impact of environmental releases of hazardous substances or petroleum products on soil and in groundwater. During any remediation project, the first step is to evaluate the available data and fill gaps, if necessary. As detailed in Section I.B.I of this proposal, Walsh is an 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. 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. 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 ■ Sparging/vapor extraction of soils and ground water ■ Monitored natural attenuation 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 At a former pesticide warehouse in Northeastern Colorado, Walsh excavated and disposed of thousands of cubic yards of soil contaminated with petroleum, solvents, radionuclides, heavy metals, "special waste," and other hazardous wastes. 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 U.S. Bureau of Land Management (several sites), State of Colorado (four CERCLA sites), EPA Region VIII (Clear Creek Fort Collins Env Services 2007 v8 Page 14 SUSAN SCHERNER Walsh Senior Landscape Architect KEY EXPERTISE ✓ Native Plant Establishment ✓ Wildlife Habitat Design ✓ Wetland Planting Design and Installation ✓ Management of Large -Scale Native Plant Installations ✓ Post -installation vegetation maintenance and management ✓ Natural Areas Planning and Management ✓ Analysis and Restoration of Road Impacts ✓ High Elevation Landscape Design EDUCATION, CERTIFICATIONS, AND SEMINARS MLA, Landscape Architecture, Utah State University, 1989 BLA, Landscape Architecture, Utah State University, 1987 BA, Liberal Arts, Knox College, 1979 Graduate coursework in GIS, University College, University of Denver, 1994-95 Registered Landscape Architect in Wyoming Spanish Intensive, Colorado Free University, Denver, 2003 Low Impact Development: Ecologically Functional Stormwater Management, 2006 AutoCAD EXPERIENCE SUMMARY Ms. Schemer has 19 years' experience in Landscape Architecture, applying ecological theory to natural areas planning and design.

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. mr\propo.valdsk\fan collins\07 ens services rebid\fort collins resumes\spence 06 doc Stanley C. Spencer, REM, CGWP Page 3 ENVIRONMENTAL SERVICES FOR THE CITY AND COUNTY OF DENVER. As Program Manager for Walsh's service contract with the City and County of Denver, Mr. Spencer served as Project Manager on a wide variety of projects. 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. Contaminated Materials Management Plan. Mr. Spencer prepared a materials management plan for redevelopment of a large urban industrial parcel for the City of Denver. The scope of work included sampling and analysis of soils excavated from approximately two city blocks. The purpose of the investigation was to determine if the soils were contaminated with industrial chemicals or RCRA regulated heavy metals and determine the waste classification for disposal or recycling. Laboratory analyses were compared with appropriate regulatory and guidance documents to classify waste and provide clean-up standards. Material management options were provided including treatment, institutional controls, or offsite disposal at an approved facility. Phase 1 and Phase H Environmental Site Assessment, Annex. Mr. Spencer was project manager for environmental assessment prior to re -construction and expansion of a large office complex for the City and County of Denver. The scope of work included an ATSM Phase I ESA, asbestos and lead -based building inspection, and a Phase II subsurface investigation. The Phase II including sampling and analysis of soils and groundwater to determine classification of excavated materials. Ground water quality was assessed to determine treatment requirements prior to de -watering discharge under a NPDES permit. A geophysical survey was performed using ground - penetrating radar to map subsurface features such as tanks or foundations. The investigation was completed on a rapid turnaround basis, allowing the project to proceed with no delay due to environmental concerns. SITE INVESTIGATION AND REMEDIATION OF A WAREHOUSE CONTAINING HAZARDOUS WASTE Mr. Spencer managed this project where WALSH characterized the contents of 97 drums containing unknown substances found in a warehouse purchased by a state department of transportation for highway improvements. The contents of each container were analyzed for volatile and semi -volatile organic compounds as well as Resource Conservation Recovery Act (RCRA) hazardous characteristics that included the eight regulated Toxicity Characteristic Leachate Procedure metals. Analytical results were used to determine the RCRA status (solid or hazardous waste) of the drums and formulate a disposal plan to ensure regulatory compliance and limit the client's potential future liability for the disposed wastes. Following drum disposal, soil borings were drilled and monitor wells installed at this site to determine the m:\Vmposaldsk\fon collins\07 env services rebi&fon colons res=es\spencc 06,doc Stanley C. Spencer, REM, CGWP Page 4 impact that improper chemical storage, handling, or disposal may have had upon soil or ground water quality. SITE INVESTIGATIONS AND REMEDIAL ACTION, DOE ROCKY FLATS PLANT Mr. Spencer managed investigative and remediation services on ten separate Operable Units at the DOE Rocky Flats Plant under various subcontracts. Under the RI/FS program, over 2,000 soil gas samples and shallow soil were collected and analyzed. RI/FS investigations are conducted under the terms of the interagency agreement between U.S. DOE, U.S. EPA, and the Colorado Department of Health. The purpose of soil gas surveys is to provide screening level data and initial definition of subsurface contaminant plumes associated with past disposal practices and accidental releases. Surveys have been conducted within operating and closed landfills, evaporation ponds, and drum storage/disposal sites. In addition to radionuclides, contaminants of concern comprise a wide range of volatile organic compounds including chlorinated solvents, hydrocarbons and various degradation byproducts. • Soil gas surveys have proven to be the most economic method of acquiring large quantities of subsurface data with short turnaround times. The surveys have been used to refine drilling and monitor well locations and to acquire preliminary data for conceptual design of vapor extraction remediation systems. WALSH'S system, while portable, attains much lower detection limits and superior analyte identification over the field grade GCs used by most contractors. ■ For the site ecological risk assessment, a large-scale survey of soil invertebrates was conducted in the buffer zone surrounding the plant. The purpose of the study was to determine the potential migration and impact of radionuclides on the microbiotic community surrounding the plant. ■ Under Waste Management and Remediation, Mr. Spencer managed the Accelerated Sludge Removal Project (ASRP) at Rocky Flats. The Solar Evaporation Ponds contained mixed hazardous/radioactive liquid process wastes from industrial operations. Because of the potential environmental hazard from leaching into ground water, DOE committed to emptying the ponds to 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. ■ Under the Remediation Feasibility Program, Mr. Spencer managed the Phase I and Phase II Soil Vacuum Pilot Projects Accelerated Sludge Removal Project (ASAP) at Rocky Flats. The Solar Evaporation Ponds contained mixed hazardous/radioactive liquid process wastes from industrial operations. Because of the potential environmental hazard from leaching into ground water, DOE committed to emptying the ponds to meet regulatory 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.

He is the Manager of Walsh's Asbestos/Lead group. The group performs certified asbestos inspections, management and planning for asbestos removal and air monitoring to assure compliance with local, state and federal regulations. Mr. Tarasar's technical expertise includes asbestos and lead projects, industrial hygiene monitoring and implementation of safety controls, and regulatory compliance under EPA, OSHA, and Fire and Building Codes. KEY PROJECTS CITYAND COUNTY OF DENVER Mr. Tarasar has performed inspections and has served as the Program Manager for Walsh's work on many of CCOD's most visible asbestos and lead projects, including the remediation and demolition of Currigan Hall, McNichols Arena, the remediation of the Denver Coliseum, the City and County Building, Denver Center for Performing Arts, Denver Botanical Gardens, Red Rock State Park and the Minori Yasui Building. FITZSIMONS REDEVELOPMENTAUTHORITY At the former Fitzsimons Army Medical Center, WALSH has conducted inspections and has overseen the remediation and demolition of over 80 buildings. Mr. Tarasar has served as Program Manager, leading a team of 12 individuals, which has inspected buildings for asbestos, LBP, and hazardous materials, and provided remediation and demolition specifications. WALSH managed the remediation and demolition contractors throughout the removal and demolition project. The buildings total about 400,000 square feet, and include residences, office buildings, jails, greenhouses, and other buildings. In addition to addressing the built environment Walsh designed the asbestos soil management plan for the facility. This involved working closely with the stake holders and regulators to construct an field approach where no written regulations applied. We were able to achieve the most economical approach while still being within the regulatory guidelines. Steve Tarasar Paee 2 ASBESTOS MITIGATION AT INTERNATIONAL AIRPORT, LIMA, PERU. Mr. Tarasar was a senior specialist on a major renovation at the Jorge Chavez International Airport in Lima, Peru (being conducted by Bechtel). Walsh performed an asbestos inspection and created an asbestos removal design for the passenger terminal of the main airport. Because all aspects of the renovation had to be performed on the airport's high ceiling while the airport remained in normal operation, Walsh had to construct a 30-ft. high platform that enabled passengers to pass underneath it while Walsh personnel worked. Walsh also trained and monitored all Peruvian workers taking part in the project, due to the fact that there are no asbestos regulations in Peru. Walsh used a combination of U.S. EPA, U.S. DOT, and Colorado state regulations as guidelines for this project. BYRON ROGERS FEDERAL COURTHOUSE At the 5-story, 600,000 sqft, Byron Rogers Federal Courthouse for the General Services Administration Walsh conducted the building inspection, design specifications and oversaw the remediation of the building for asbestos and lead. The project included environmental inspection, sampling, recommendations, cost estimation, project design, drawings, bid documents, and bid review. DENVER REGIONAL TRANSPORTATION DISTRICT (RTD) LIGHT RAIL CORRIDOR Mr. Tarasar inspected, designed, and managed the asbestos containing materials/lead based paint removal project for 20 buildings that were scheduled for demolition by RTD. This project was completed two months ahead of the original estimated schedule. The project included environmental inspection, sampling, recommendations, cost estimation, project design, drawings, bid documents, and bid review. Mr. Tarasar provided on -site administration, sampling and air monitoring. In addition to coordinating analytical services for bulk, air and separated lab QC, Mr. Tarasar secured 2-hour analytical PCM/TEM services through independent laboratories. PUBLIC SERVICE COMPANY OF COLORADO BANNOCK CENTER Mr. Tarasar managed asbestos inspections for 18 buildings located at the Bannock Center site owned and operated by Public Service Company of Colorado. This involved the removal of asbestos and lead from a public occupied training facility, sometimes in conjunction with limited interior demolition and remodels. Mr. Tarasar group prepared a detailed operations and maintenance plan for ongoing management of the remaining asbestos in place. COLORADO DEPARTMENT OF CORRECTIONS FREEMONT, COLORADO TERRITORIAL, AND PUEBLO YOUTH CORRECTIONAL FACILITIES This project involves asbestos inspection, assessment, abatement design, project administration, management plans, and air monitoring for 44 buildings for the Colorado Department of Corrections. Mr. Tarasar group managed the removal of asbestos from several buildings prior to renovations. UNITED STATES POSTAL SERVICE Mr. Tarasar managed asbestos and lead based paint surveys for 175 US Postal Service facilities in Colorado, Arizona, New Mexico and South Dakota. He prepared a detailed operations and maintenance plan for ongoing management of the remaining asbestos in place. RTD'S FASTRACKS PROGRAM Mr. Tarasar is the asbestos task manager for the $3 million contract Walsh has signed with the Regional Transportation District (RTD) to perform environmental services for RTD's FasTracks Program, including the West Corridor.

Walsh Enwanmcntal Scientists and Engineers. LLC City of Fort Collins, Environmental Services Since 1997, we have completed nearly 250 different projects for the City, successfully completing all on time and on or under budget. We have completed many projects in the key service areas of the Environmental Services Contract, including: Phase I ESAs. Walsh has completed 76 different Phase I ESA projects for the City, providing ESAs on approximately 250 properties. Walsh has provided Phase I ESAs on large areas, including the Soapstone Ranch, Halligan Reservoir Expansion, the Downtown River Corridor, New Police Station Complex, Timberline Avenue Extension Project, and the Lee Martinez Park Development. Many Phase I ESAs have been completed on rural agricultural properties for the purposes of City Natural Areas expansion/ infill purposes and for conservation easement purposes. Walsh has provided Phase I ESAs on numerous commercial properties, including former service stations, the former Prospect East Industrial Park, Resource Recovery Farm, Abraxis Art Glass Property, Former Salvation Army Warehouse, and the Ricker Brothers Warehouse. Phase II Site Investigations. Walsh has completed numerous Phase I1 site investigations for the City, including at the Former Municipal Landfill, Bartran (Turf Farm) Property, Union Pacific Railroad Property, Prospect East Industrial Park, Timberline Road Widening Project, and downgradient of the former Poudre Valley Gas Plant near the Aztlan Community Center and United Way Buildings to name abut a few. Walsh also completed drilling and sampling at the Lee Martinez Park housing development, which had been a railyard. At the City Fleet Services Building, Walsh performed quarterly ground water monitoring. Sampling activities at City Parks and Natural Areas was performed to assess potential impacts from storage and use of pressure treated wood stockpiles. Indoor Air Quality Investigations. Walsh completed indoor air quality investigations at numerous City offices including EPIC, Parks Department Shop, 200 West Mountain Avenue, Transfort Headquarters facility, Operations Services, 281 North College Avenue, City Hall, the Power and Light Building, Municipal Court, Police Dispatch, Poudre Fire Authority facilities, 405 West Canyon Avenue, and the Water Meter Shop. Potential indoor air quality issues are presently being evaluated at the New Aztlan Center building. A sampling and analysis plan and operations maintenance and monitoring plan are being developed to assure the effectiveness of a active vapor mitigation system which is has been designed for installation to the new building by Walsh engineering staff. Asbestos and Lead -based Paint Inspections. Walsh completed asbestos and/or lead -based paint inspections and hazardous material inventories for Fort Collins at approximately 40 properties. Notable facilities include the Lincoln Center, Aztlan Community Center, City Hall, CSU Lory Student Center (for joint CSU/City Transit Center Project), Collindale Golf Course Clubhouse, Lee Martinez Farm, Resource Recovery Farm, Railway Car Barn, the Bus Depot Building and other locations. Walsh has provided additional asbestos and lead consulting services to the City including, Specification/work Plan development, bidding support and project oversight activities. Walsh has work with City staff to determine the appropriate level of oversight necessary to achieve project goals within acceptable risk tolerances of the City. An Asbestos -Contaminated Soils Work Plan has been prepared for construction activities for the New Aztlan Center and has been approved by state representatives. Advising the City on Potential Environmental Concerns, Regulatory Programs, Releases, and Practices. Walsh provided consulting services on a number of projects, including Health and Safety Planning and Sampling for various facilities with reported indoor air quality concerns, H&S and construction oversight on New Aztlan Center building and evaluation of conditions of several properties considered for acquisition by the City.

Our senior engineer has more than 25 years experience working with the EPA to determine waste minimization procedures and guidelines for a variety of industries. 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.B.3 Eco%gica/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. Walsh's Ecological Restoration and Ecological Services Groups have performed assessment services for hundreds of projects throughout the U.S., averaging over 40 assessment projects per year. Our thirteen - person team comprises 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.

LL.0 Environmental Site Assessment and Closure under Voluntary Cleanup and Brownfields Programs, City of Fort Collins Walsh helped the City win an EPA Brownfields Grant of $250,000 for assessment in the Poudre River Corridor. Walsh performed a large-scale multi -property (133 parcels) modified Phase I ESA of the corridor. Walsh completed extensive Phase II site investigation work under the Brownfields rant, and has worked with the City to resolve contamination issues prior to redevelopment. Issues in the corridor have included: former rail lines and sidings; passenger and freight depots; Harmony & Ranchway mills; a concrete batch plant, storage yards, a light and power plant; a sugar plant; a pickle plant; a city dump; the Poudre Valley gas plant; and numerous light industry, commercial and residential locations.} Walsh has prepared an Application under Colorado's VCRA program for a No Action Determination for the former City landfill along the banks of the Poudre River in the Downtown Corridor. The VCUP application concisely summarized historic site investigation data generated by a multitude of environmental consultants. This NAD request was recently approved by CDPHE representatives. Walsh prepared an Application for a No Action Determination under VCRA for the Former City of Fort Collins Municipal Landfill, visible in the upper left of this photograph. This NAD request has been recently approved by state In this corridor, Walsh identified a major source of representatives. groundwater contamination, the former Poudre Valley Gas Plant Site, and completed an extensive Phase II sampling program. Our work identified an ongoing release of coal tar liquids to the Poudre River, and lead to extensive involvement of EPA in evaluating the concerns limiting future development in the Corridor. In addition, a recently completed Phase II site investigation has documented that a regional chlorinated solvent ground water plume is not being caused by former landfill activities but is related to an unidentified off -site source. Walsh provided continuous, comprehensive technical support to the City through the multi -year completion of an approximately $17 million remedial action at the site by the responsible parties. The resolution of this major contamination issue will allow the City to proceed with an estimated $7 million investment in a new community center, and other revitalization projects. Walsh also assisted the City by providing recommendations on potential environmental liabilities involved with potential public acquisition of private property, and with a variety of public meetings for the project. In addition, we produced and maintained a public web site for the City that describes the environmental issues within, and proposed development of, the river corridor during principal site investigation work. We have assisted the City with Public Outreach, with printed materials, web -based information, and presentations at public meetings. We have provided Quality Assurance Project Plans (QAPPs), Sampling and Analysis Plans (SAPs), Health and Safety Plans (HASPS) and numerous reports to Fort Collins under this program. Our Phase II Field Sampling Plans have been accepted by EPA Brownfields staff, and have been successfully implemented. Walsh assisted the City with the river restoration aspects of the Cache La Poudre River cleanup project acting as a liaison throughout the project, from the initial negotiation of restoration requirements, through the construction process, and the negotiation of maintenance and monitoring requirements. During the design development phase, specific tasks included the review and editing of design plans and Page B-10 Walsh E-.nvironmcntai Scientists and Engineers, L.L.0 specifications, and attendance and recommendations during design development and coordination meetings. During this phase Walsh provided specialized expertise in river restoration design, bioengineered bank stabilization measures, instream habitat enhancement, and riparian corridor restoration. Walsh assisted the City with oversight of the restoration and landscape contractors, recommendations for specific construction methods, and assistance with logistics. Walsh engineers are currently developing designs and specifications for the vapor intrusion protection system for the new Northside Community Center building. Walsh is also preparing Sampling and Analysis Plans for indoor air monitoring at the new building. This work is being done under the approved NAD with the State's Voluntary Cleanup Program. The work will assure that public health and safety are protected and the new structure fully complies with the Reasonable Steps and Institutional Controls required by the CERCLA removal action at this site.

Inspections, Abatement/Demolition Plans, Oversight, and Remediation of Contaminated Soil for Fitzsimons Redevelopment Authority and Other Clients At the former Fitzsimons Army Medical Center, Walsh has provided environmental consulting services for site and roadway development over the course of several years. Our tasks have included: ■ Assessment and oversight of abatement and demolition of 113 buildings and associated utilities such as steam tunnels, vaults, and direct buried piping; and ■ Remediation of soils contaminated with diesel free product. The 578-acre Fitzsimons site is undergoing a $4.3-billion renovation and transformation into a square mile dedicated to in -patient care, education, basic science research and bioscience research and development. Asbestos and Hazardous Materials Tasks. Walsh has provided asbestos, lead -based paint and hazardous materials building inspections; demolition and abatement design; and demolition and abatement oversight. These were completed on a fast -track approach, using multiple Walsh inspection teams. We also provided oversight of many remediation and demolition contractors for the following entities at Fitzsimons: ■ Fitzsimons Redevelopment Authority — 41 Buildings ■ City of Aurora — 14 Buildings ■ Xcel Energy Company — 4 Buildings ■ State of Colorado — 8 Buildings ■ University of Colorado Health Sciences Center — 46 Buildings Inspections were conducted in accordance with EPA, CDPHE and OSHA requirements. The inspections were following regulatory guidance for demolition projects. We also inspected painted components for lead -based paint. Walsh inventoried regulated materials in each building that were considered universal waste, hazardous waste or other regulated material. Walsh conducted asbestos and lead inspections, prepared remediation design, and provided abatement and demolition oversight for 113 buildings at Fitzsimons. Inspection of interior spaces included destructive investigation necessary to identify hidden and concealed materials such as piping behind walls or inside chases. Destructive investigation was crucial in identifying asbestos -containing linoleum located under multiple layers of non -asbestos flooring. Inspection of exterior spaces included inspection of exterior stucco systems. As part of the exterior stucco inspection, Walsh was able to conclusively implement a system for inspection and abatement of asbestos -containing "patching material" installed over cracks as part of historical repair activities. With the use of the on -site laboratory, Walsh was able to determine the extent of the patching material on a real-time basis, saving time and money. This system saved millions of dollars, because other consultants had misinterpreted the data and classified the entire exterior stucco system as containing asbestos. Inspection, abatement design, and abatement of crawlspaces have been conducted using techniques targeted to remediation of contaminated soils. This has ensured proper removal of contaminated soils, while avoiding unnecessary time and expense of soil remediation in crawlspace areas without contamination. Walsh's extensive experience with crawlspace and asbestos/soil contamination issues has yielded design specifications that ensure efficient yet effective removal, including use of vacuum Page B-12 WA9h m ironmental Scientists and Engineers. H.0 technology, coupled with measurement systems to ensure and document that asbestos contamination has been removed in accordance with regulatory standards. As part of site redevelopment, removal of the extensive underground utilities, including water, electrical, gas, sewer and steam lines, including vaults and tunnels, have been inspected and remediated prior to demolition. During the course of site excavation activities at Fitzsimons, several areas have been identified as having asbestos -containing debris mixed with soil -- the result of historical demolition of structures prior to regulation of asbestos. Acting as liaison between building owners and CDPHE, Walsh has been instrumental in developing standardized soil remediation flow charts and protocols that provide consistent and cost-effective methodology for addressing asbestos contamination in subsurface soils. Walsh's experience at Buckley Air Force Base, Lowry, and other asbestos/soil contamination projects provided valuable experience in this area. Walsh was also instrumental in cost recovery efforts by providing site characterization information, technical review, and cost estimating. Page 8-13 Walsh Environmental Scientists and Engineers.

Advise the City in ...environmental permits... including preparation and submittal... Walsh handles many projects that require regulatory assistance and ultimately, permit approvals. Once ecological constraints are identified and delineated during the ecological assessment phase, we typically hold a strategy meeting with the client. During the strategy meeting, Walsh provides recommendations regarding avoidance and minimization of impacts, potential design modifications, and regulatory strategies which help to make projects more cost- and time -effective. More complex projects may also require a pre -application meeting with the regulatory agencies to confirm strategies. We have developed excellent, long-term relationships with the federal, state and local regulatory communities in Colorado. This experience and insight allows us to guide our clients through the regulatory process in the most expeditious manner. Additionally, Walsh maintains a database of grant funding opportunities for both private and public restoration, habitat and recreational resource improvement projects. We have assisted municipal and other clients in preparing applications and receiving federal, state and local grant funding.

Fort Collins Env Services 2007 v8 Page 18 Yatsh Environmental Scientists and Engineers. LLC properties. More than 90 boreholes and trenches were undertaken, and hundreds of waste, soil, and groundwater samples were collected and analyzed. Building and Property Inspections. Walsh conducted asbestos, lead -based paint, and hazardous materials assessments of 35 buildings and their contents, as well as 136 drums and containers of chemicals and other equipment, materials, and debris located on the properties. Voluntary Cleanup Plan for Hazardous Materials. Walsh developed a site -wide Voluntary Cleanup Plan (VCUP) which outlines the extensive precautionary Walsh industrial hygienists sampled 136 drums measures contractors and employees will take to and containers of unidentified materials that were conduct a safe cleanup. The VCUP incorporated found on the properties. The contents were Materials Management Plan, a Methane Vapor classified and disposed of at hazardous waste and solid waste landfills. Those contents that could be Mitigation Plan, a worker Health and Safety Plan, and recycled were shipped to appropriate facilities. other documents. The VCUP was approved by the Colorado Department of Public Health and Environment (CDPHE) on April 18, 2006. The intent of the VCUP was to provide a clear path to implementing a remedy that supports redevelopment. Additionally, it helped assure the investors and insurance brokers that the work was approved by the State. Following the completion of the VCUP, Walsh, on behalf of the General Contractor, wrote a Contractor's Plan of Operation. The purpose of the this Plan was to secure a Comfort Letter from CDPHE stating that not only would the work be done in accordance with the VCUP group, but also in accordance with the Solid Waste regulations. This was keenly important due to assuage the State's concerns that the landfill could be destabilized due to Site activities. The CPO included the Design Analysis Report for the Water Quality Swale that provided the design justification for running the WQS alignment across the landfill cover. Remediation and Other Engineering Designs. During excavation of landfill materials, a variety of measures are being taken to minimize nuisance odors to local residents. This includes limiting the area of landfill excavation, and using soil cover, chemicals and foams to suppress odors. The landfill excavation and replacement with clean fill material is being done on a continuous basis to minimize the area of exposed landfill material and to get the work done as soon as possible. Buildings will contain an active vapor mitigation system, consisting of a below floor slab venting system with monitors and alarm systems. In addition, all utility corridors and parking lots will be designed with passive venting systems to safely vent methane and any below surface gasses harmlessly to the atmosphere. All systems will be designed and installed in accordance with the CDPHE approved Vapor Mitigation Plan. Platte River Stream Restoration. The project includes the area of the confluence of the Platte River and Bear More than 700,000 cubic yards of landfill material are being excavated over an 8- month period. Walsh is providing continuous construction monitoring during this process. Page B-15 Walsh Environmental Scientists and hngincers, LLC Inspections/Oversight and Phase I Obermeyer Redevelopment Project Walsh provided environmental consulting services for Szymanski -Ray and Obermeyer Redevelopment Corporation for the redevelopment of a city block in Aspen containing 14 commercial and residential structures.

Prior to tenants' vacating the and II ESAs for Demolition of 14 Buildings - Walsh provided rapid-tumaround Phase I and II ESAs and building inspections during demolition of 14 buildings in Aspen for redevelopment. buildings, Walsh conducted a Phase I ESA to identify potential issues on the property. Asbestos/Lead/Hazardous Materials Inspection and Oversight. As tenants vacated each building, Walsh provided fast -track completion of inspection by conducting destructive investigations to ensure hidden and/or concealed materials were discovered and addressed. Inspections were done under the protocol described in project description #1 (above). In accordance with EPA and CDPHE regulations, materials determined to be RACM were removed prior to building demolition. Walsh provided an abatement design document for the removal of all RACMs and other regulated materials. Walsh also provided abatement oversight during the project, providing inspection and air monitoring for regulatory and contract compliance. Communication, tracking and scheduling with the abatement contractor, demolition contractor, general contractor and owner under the fast -track approach was also part of the abatement oversight function. Advanced regulatory notification and scheduling allowed the abatement contractor to commence building preparation within hours after the tenants vacated a building, ensuring the buildings were on -schedule for demolition. The hazardous materials inspection not only evaluated those regulated materials within the building structures themselves (e.g. mercury vapor lamps, thermostats, etc.), but also materials left inside the buildings by occupants, such as those shown here. This included drums of chemicals, tires, and many other items that had to be disposed of with special handling. Page B-17 s Walsh Environmental Scientists and Engineers. H.0 Walsh's inspections identified vermiculite loose fill insulation material in the hollow cells of cement masonry units used to construct the exterior and interior walls of several large warehouse buildings. Due to ongoing EPA vermiculite cleanup actions at Libby Montana, Walsh conducted a compliance review with EPA, CDPHE and OSHA requirements since regulation and policies regarding vermiculite are in flux. Walsh also reviewed state-of-the-art analytical procedures including the "Cincinnati Method" currently under review by EPA as potential methodology for analysis of vermiculite insulation. This effort provided the owner and contractors with confidence and knowledge to demolish the buildings containing the vermiculite insulation in a safe, yet cost-effective manner. The structures were inspected using a field portable XRF for the presence of lead -based paint for purposes of hazard communication to the demolition contractor, and to identify those structures subject to hazardous waste determination requiring supplement TCLP testing and analysis. Walsh conducted a "hazardous building component" inventory for each structure to identify typical building components that potentially contain hazardous materials, and that may require special handling, disposal and/or disposition of these materials. The removal, handling and disposal of hazardous materials were included in the abatement design. Additional hazardous material inventory was required as tenants vacated buildings, to ensure proper disposition of regulated/hazardous materials left by tenants (paints, chemicals, tires, etc.). The following materials were addressed by the building inspection: ■ Sand oil interceptor trench ■ Computer equipment (lead, mercury) ■ Cooling/refrigeration equipment (CFCs) ■ Fluorescent lamps (mercury) ■ Light ballasts (PCB -containing) ■ Mechanical equipment (fluids) ■ Mercury gauges/thermometers ■ Mercury thermostats ■ Mercury vapor lamps ■ Rechargeable batteries ■ Storage tank/vessel (fluids) ■ Transformers (PCB -containing) ■ Stored chemicals and paints ■ Smoke detectors • Computer equipment ■ Batteries ■ Propane tanks ■ Tires The Phase II ESA identified lead and other metals in soils from a former assay office and mine tailings dumps. Walsh treated 10,000 cubic yards of soils, and disposed of the most contaminated portion in a landfill (after ensuring that the landfill acceptance criteria were met). The clean portion was used as road base at a nearby road construction project. Phase II ESA and Remediation of Contaminated Soils. During and after the demolition phase, Walsh conducted a Phase II ESA that determined the presence of lead and other heavy metals in soils beneath the buildings. These came from a former mineral assay office on the property, as well as mine tailings that had been disposed of on the property. Walsh characterized and segregated the tailings, and treated over 10,000 cubic yards of contaminated soils with lime to stabilize the metals at a level below the 1 ppm detection limit. Following stabilization, we ran TCLP tests to ensure that the soils met the acceptance criteria of the landfill. This also allowed some of the material (that was cleanest) to be put to beneficial re -use, most of which was used during construction of a nearby roadway as road base. By doing this, significant disposal fees were saved.

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. We have also used health risk assessment to assist clients with evaluation of hazards presented by asbestos contamination in soils. Walsh has demonstrated our ability to provide high quality risk assessment services to its clients using the expertise of our parent company, E&E, 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, to address asbestos in soils at a Fort Collins Env Services 2007 v8 Page 23 Walsh Environmental Scientists and Engineers, LLC Open Space, Trails, and Parks Master Plan for the City of Thornton: Walsh provided ecological services in conjunction with a city-wide management plan that included identification and evaluation of important wildlife, vegetation, and aquatic resources and recommendations for future acquisition and management. Wetlands Permitting and Threatened/Endaneered Species Support for Jefferson County: Walsh provided support to the Jefferson County Open Space Department in conjunction with planned development of visitor facilities at three open space parcels. Facilities included parking lots, picnic shelters, restrooms, trails, and trailhead signage associated with passive recreational use of the Flying J Ranch, Mount Galbraith, and Beaver Brook parcels. Resource Inventory, City and County of Broomfield: Walsh is currently participating in design of the Section 30 Recreation Center, which has included issues related to prairie dogs and biotreatment of stormwater runoff. Walsh has also conducted a resource inventory and is developing long-term use and management scenarios for The Field and Brunner Reservoir in the City of Broomfield. Issues addressed included conversion of cropland to native grassland, as well as the preservation and enhancement of an existing wetland complex. Open Space and Trails Prairie Doe Management Policy, City and County of Broomfield: Walsh recently completed a prairie dog management policy, developed in concert with City staff and the Open Space and Trails Advisory Committee, to address prairie dog control, relocation, or preservation on public and private lands within Broomfield. Ecological Evaluation, City of Longmont Parks and Recreation: Walsh evaluated ecological conditions of the Sandstone Ranch open space parcel and helped prepare a long-term management plan that identified areas to be preserved, areas to be enhanced, and areas to be restored. Walsh developed design specifications for the open space and ballfields portions of the site, including trail alignments. Prairie Dog Mapping Survey for the City of Boulder Open Space and Mountain Parks Department Walsh recently completed a mapping survey of black -tailed prairie dog colonies for the City of Boulder. The purpose of the survey was to obtain accurate colony size, location, and ecological condition data, as well as information concerning surrounding land uses and existing barriers or constraints to colony expansion. Methods used in the study were designed to be easily repeated for future tracking of colony size and status, using a GPS receiver unit for on the ground mapping and GIS data analysis. Threatened or Endaneered Species Clearance and Habitat Enhancement Desien Centennial Bike Path - Proiect for the City of Boulder Transportation Department: Walsh conducted T&E surveys (with emphasis on Preble's meadow jumping mouse, Ute ladies' -tresses orchid, and Colorado butterfly plant) for a bike path project located along 1-kilometer multi -use trail along a major canal and riparian corridor. Although T&E species were recognized as unlikely to occur, obtaining formal clearance from the U.S. Fish and Wildlife Service was a City requirement. For the same project, Walsh designed, provided construction for, and has conducted monitoring of a habitat enhancement project on the canal. City of Louisville Open Space Department - Ecological Services: Walsh participated in an inventory of ecological resources on city -owned open space land. The project resulted in development of a management plan that made recommendations for future uses of the parcels and nearby lands that would balance the need for transportation corridors and passive recreational (e.g., trail) uses where appropriate while preserving or enhancing areas of special ecological value. The latter included the Coal Creek riparian corridor, some areas of semi -intact native grassland, and areas to be used by the City for relocation of prairie dogs. Fort Collins Env Services 2007 v8 Page 30 Walsh Environmental Scientists and Engineers LLC in soils. We reviewed the Baseline Risk Assessment and Relative Bioavailability Study prepared by EPA. This included verifying the risk model results and reviewing input parameters to determine if the BRA provided a reasonable estimate of actual risk posed by the site. Defense Department Contractor Indoor Air Investigation and Human Health Risk Assessment: At a defense manufacturer's plant in Littleton, a ground water plume containing TCA and DCE extends over 300 yards. When solvents were discovered in the ground water in surrounding residential areas, the CDPHE directed the owner to determine whether vapors might be impacting indoor air quality. For the Human Health Risk Assessment, we developed a list of compounds of toxicological significance and evaluated risks and exposure pathways for very low concentrations of a variety of solvents. We developed an air sampling program and sampled 50 homes on a quarterly basis. Human Health Exposure/Risk Assessment for Heavy Metals Utah: At the Sharon Steel site in Midvale, Utah, Walsh/E&E prepared a third -party exposure/risk assessment to determine the need for removal action at an old smelter and milling site located south of Salt Lake City. Ecological Risk Assessment, Mojave National Preserve, California: For the National Park Service, Dr. Mach (of Walsh/E&E) oversaw the ecological risk assessment for a lanthanide mining site where decades of tailings disposal had resulted in contamination of part of the Mojave National Preserve, threatening critical habitat for many desert wildlife species. We reviewed work plans; data evaluation reports; and ecological risk assessment deliverables prepared by other consultants. f.C.7 Air -Related Projects Litigation Support for Diesel Fuel Release, Mandan, North Dakota: At a spill site in North Dakota, Walsh investigated the potential for diesel -related contaminants in groundwater to have migrated through soil vapor into indoor air. The site was characterized by a LNAPL (light non -aqueous phase liquid) pool estimated to contain 3 to 5 million gallons of diesel fuel. Air Quality Consulting for Power Plant: For an electric utility company in Washington State, Walsh is currently evaluating the air emissions impacts for the conversion of a coal fired power plant to new, cleaner burning technology. Walsh is calculating the emissions reductions that will occur, and evaluating options for modifying or appending existing air emissions permits. Air Emissions Permitting for New Cement Plant: For a Peruvian cement company that is opening a new limestone quarry and adjacent cement plant in northern Arizona, Walsh is currently evaluating emissions that will emanate from the plant and preparing air quality permit documents to submit to the State of Arizona. Air Emissions Evaluations for BLM: For the BLM, Walsh evaluated air emissions (including fugitive dust from vehicle traffic on unpaved roads and emissions from gas wells and pipelines) that would result from a revised land use management plan for the Roan Plateau area west of Rifle, Colorado. Five different land use management scenarios were evaluated, and the potential emissions for each scenario were calculated and compared to evaluate impacts to air quality in the region.

She specializes in stream corridor restoration with an emphasis on natural sustainability and habitat improvement. Ms. Ash has worked on a broad range of projects from river restoration, including stable channel design, streambed and bank stabilization, bioengineering treatments, instream structures, and aquatic, wetland, and riparian habitat improvement, to wetland mitigation design, surface water control, erosion and sedimentation control, mine site remediation, and water feature development. Project components have included site evaluations, impact assessments, grading and planting plans, hydrologic and hydraulic analyses (including HEC programs), geomorphic analyses, water budgets, water distribution systems, volume estimation using AutoCAD Land Desktop software, construction oversight, construction cost estimation, and monitoring and maintenance plans. Ms. Ash has extensive construction support and fieldwork experience on engineering and ecological restoration projects. Construction support services include site layout, survey checks, onsite guidance for design plan implementation, environmental compliance assistance, troubleshooting and field modifications, general operations support, and as -built surveys. Fieldwork expertise includes preliminary assessments and jurisdictional delineations of wetlands and waters of the U.S. and existing conditions assessments for stream and wetland projects, including cross -sectional and thalweg surveys and reference reach and site feature mapping using GPS, auto level, and total station. Ms. Ash also has extensive experience on wetland permitting and mitigation projects in Colorado and Florida. She has performed wetland mitigation monitoring for Section 404 permit compliance to assess vegetative survivability and composition, undesirable plant species invasion, wildlife utilization, and soil and hydrologic conditions. Her work has included impact assessments and design of replacement wetland habitats to meet local and Federal permit requirements. Julie E. Ash, P.E. Paee 3 study methodology utilized the United States Geological Survey (USGS) PHABSIM suite of models, capable of developing habitat indices for the above resources and being integrated with proposed hydrology downstream of the reservoirs in order to assess the effects of different project operations to the target resources. CHANNEL IMPROVEMENT AT INACTIVE MINE SITE, JAMESTOWN, COLORADO Ms. Ash designed a channel realignment and surface water control plan in support of a mine site remediation for an 11-acre inactive fluorspar mine located in the foothills of Boulder County, in the Town of Jamestown, Colorado. The project was conducted as a Voluntary Cleanup Project (VCUP) under the State's Voluntary Cleanup and Redevelopment Act (VCRA). Goals of the remediation were to reduce surface and groundwater interaction with contaminated materials to improve water quality in downstream receiving streams and to reduce onsite safety hazards and liability. Remedial activities consisted of surficial waste rock removal across the site, formal closure of onsite adits and shafts, subsidence pit fill and mounding, realignment of an intermittent tributary, surface water runoff management, and site -wide revegetation. Ms. Ash designed the realigned channel to imitate the function and appearance of the natural channel's step -pool configuration. Small, closely spaced rock drop structures were specified along the channel for energy dissipation and to create flow variability. While the channel was designed to withstand flows in excess of the 100-year storm, the surface treatment for the channel bed utilized soil and rock gradations found in the natural channel. The bed material will be mobilized in storm events and can be naturally scoured to create localized pools, imitating functions occurring in the reaches above and below the diversion channel. Low flow notches in the drop structures increase sinuosity and encourage low flow concentration to prevent overly wide, shallow flow, which is a common constraint to aquatic habitat. Ms. Ash also designed the surface water control plan for the mine site, which provides safe conveyance of runoff flows and prevents detrimental rilling. Additionally, the controls effectively separated clean runoff from potentially impacted water, optimizing the site for future treatment options. WASTE LOAD ALLOCATION ASSESSMENT FOR INACTIVE MINE SITE, JAMESTOWN, COLORADO For this project, she conducted preliminary sreamflow estimations in support of waste load allocation assessments within the drainage system below an inactive mine site. Streamflow calculations included approximation of discharge -frequency relationships for low flows (i.e., acute and chronic low flows) for known points of concern throughout the watershed. Discharge information was used to preliminarily estimate allowable water quality conditions in downstream receiving streams. The assessments are designed to be repeatable and refined as better data are collected from numerous proposed monitoring stations. DRAINAGE SYSTEM DESIGN FOR MINE SITE REMEDIATION, FAIRFIELD, UTAH Ms. Ash designed a three -channel system for surface water control at a Utah mine site. The channels drain small basins, however, the design flows are in excess of the 100-year flood event — and often in excess of the 500-year event — such that adequate protection is provided to the tailings repository. The design included protection for tributary drainages entering the remediation site from several surrounding canyons. A series of check dams were included in the design to provide grade control, an important insurance measure to the adjacent repository, and to reduce flow velocities and scour potential. More natural and less expensive grass -lined channels were specified in lower flow and lower risk areas. A naturalized vehicle crossing was designed for one of the grass -lined channels, using a Geoweb porous pavement system. In addition to a more aesthetic look, the Geoweb system is more functional as it avoids the impacts associated with typical, impermeable paving. LEFT HAND CANYON RESTORATION, BOULDER COUNTY, COLORADO Ms. Ash conducted a hydrologic analysis and channel network design for a high elevation meadow, located within a heavily used Off -Highway Vehicle (OHV) area in Left Hand Canyon. The meadow had been severely impacted over the years resulting in loss of vegetation, increased erosion, compacted soils, and destabilization of a small tributary of Left Hand Creek. Restoration activities reestablished the upland meadow habitat, repaired denuded "hillclimbs", improved surface water runoff conveyance, and helped protect the incised tributary. The hydrologic analysis provided a scientific basis for site drainage Edward M. Baltzer Pace 2 performed sound surveys at various locations, and performed air -monitoring studies using personal and ambient air monitors.

Design site revegetation and restoration projects Walsh staff have been designing and building stream, river, wetland, riparian and wildlife habitat projects throughout the U.S. for over 22 years, including project for the City of Fort Collins. In the past eleven years, our staff have designed and implemented projects in the Poudre, 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. 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 plans (e.g., in a "turn -key" process), as well as 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: ■ Cache la Poudre river restoration design and construction assistance for the City of Fort Collins • Grant funding support, assessment and design services to the Eagle River Watershed Council for the Edwards Eagle River Restoration Project ■ Design and implementation of revegetation plans for 32 miles of stream banks and adjacent riparian habitat in Kentucky ■ Design of 900 acres of wetlands and wildife habitat at a mining Superfund site in Anaconda, Montana e. Assessment of Threatened & Endangered Species Walsh has worked on a wide variety of T&E and other special status species issues. For example, we worked with the Cities of Broomfield and Thornton to create prairie dog management plans and planning guidance. We also wrote a wildlife management plan for the City of Longmont that emphasized special status species such as prairie dogs. We have also done numerous 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 Colorado butterfly plant. We routinely conduct habitat identification and delineation, presence surveys, Section 7 consultation with the US Fish and Wildlife Service (USFWS), as well as project mitigation design and implementation and habitat restoration. Some of our projects have also included development of long-term site maintenance plans, including ongoing habitat enhancement and weed management. Recent projects involving T&E species include: ■ NEPA compliance surveys for T&E and sensitive plant species on Western Slope BLM properties ■ 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 surveys, for National Renewable Energy Laboratory sites in Boulder and Jefferson Counties • Intensive trapping surveys, as well as vegetation assessment and analysis, of Preble's meadow jumping mouse habitat throughout the Colorado Front Range, including the Fort Collins area Fort Collins Env Services 2007 vN Page 20 No Text Tom Butts Pace 3 BUCKLEY AIR FORCE BASE Mr. Butts provided inspection and reporting as a Colorado Department of Public Health and Environment representative during the 9-month removal of asbestos contaminated soil.

Both on -and off - site noise monitoring was conducted over a 72 hour period. It was determined that the major high decibel noise source was compressors powering the high pressure sludge treatment unit. A con- ceptual design was prepared which provided for a separate insulated enclosure for the compres- sors, in order to reduce noise levels to acceptable levels at the property boundary. NOISE SURVEY, IMPACT OF NEARBY ROADWAY ON PLANETARIUM, WEST PALM BEACH, FLORIDA For the West Palm Beach planetarium, Mr. Cowart was project manager for a survey to determine if noise from a nearby highway was sufficient to create vibration in the planetarium telescopes. Noise, light and vibration measurements were taken during nighttime hours. It was concluded that light pollution was the major impact on celestial viewing, and that noise and vibration were not an issue. INDUSTRIAL WASTEWATER PROJECTS PRECIPITATION OF HEAVY METALS, COPPER MINE SITE, CUBA, NEW MEXICO For the USDA Forest Service, Mr. Cowart conducted a treatability study and prepared a concep- tual design for the removal of heavy metals, such as copper, from acidic groundwater at the for- mer Nacimiento Mine site in Cuba, New Mexico. The acidic groundwater was titrated with vari- ous bases in order to determine optimum precipitation conditions. Polishing treatment was evalu- ated using an immobilized ligand to preferentially adsorb metals of concern. A conceptual design and capital and annual cost estimate was prepared for a 105 gpm groundwater extraction and treatment system, with discharge to either groundwater or surface water. DEVELOPMENT OF NPDES GUIDELINES, FOR THE U.S. EPA, 1975-1985 For the U.S. Environmental Protection Agency, Mr. Cowart directed over 75 man-years of work during a 10-year period in order to establish wastewater treatment effluent guidelines and stan- dards for industries discharging into surface waters or publicly -owned treatment works.

Freeman, Ph.D. (Cont.) diminution claims brought by residents whose property was adjacent to the facility. Four UST Sites, Alabama. Dr. Freeman directed E & E evaluations of site cleanup adequacy on behalf of the Alabama Department of Environmental Management. Using data on petroleum constituents in soil and groundwater, his team quantitatively compared site conditions with default conditions, then calculated appropriate site -specific screening criteria for each of the four sites. It was determined that the site -specific criteria had been met at two sites and that institutional controls had satisfied requirements for another site. 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. Incinerator Ash Disposal Sites, Florida. In 2005, he evaluated the utility of the IEUBK and the newly announced AALM biokinetic lead exposure models in the causal analysis of alleged lead overexposure. His ecolnpand eiwirmmne . ini w�ry.srnm. enwwenw 3 Richard W. Freeman, Ph.D. (Cont.) work demonstrated that, outside background exposure or regulatory "safe" exposure levels, the biokinetic models tend to increasingly over -predict blood lead levels in children. He further demonstrated that extrapolation of blood lead levels back in time using these biokinetic models —both in the sense of alleged overt lead toxicity and the more subtle (but increasingly controversial) neurological developmental effects —is unreliable. Dr. Freeman presented his findings at the Annual Meeting of the Society of Toxicology. He also found that EPA's newly announced AAALM model predicts blood lead level (even from background exposure) that would indicate excess risk for children. 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 (],I-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. Locomotive Refueling Sites, Mississippi. He applied a potency slope factor specific for diesel fuel to develop health -based soil cleanup levels. For these sites, Dr. Freeman also assessed potential health risks of dustbome pesticides, performed a comparative risk analysis, modeled potential exposures based on prevalent weather patterns, and calculated the lifetime exposure risk. Statewide Toxicological Evaluation, Florida. Dr. Freeman also worked for four years with the Florida Department of Health and Rehabilita- tive Services (DHRS). For one year (1988-1989), he was the director for toxicology and hazard assessment. For three years (1985-1988), he provided epidemic surveillance and toxicological investigation, primarily supporting state officials in the determination of safe exposure levels for chemical contaminants. As lead DHRS investigator on a three-year cooperative agreement with ATSDR, he completed HHRAs for National Priorities List hazardous waste sites in Florida.

STREAM AND FLOODPLAIN RESTORATION AT COAL MINING FACILITY, KENTUCKY Member of technical design team tasked with assessment and restoration of 26 miles of stream corridor following the accidental release of 250 million gallons of coal slurry into two separate drainages in eastern Kentucky. Several local drainages, unaffected by the release, were employed as reference reaches to guide channel rehabilitation and habitat improvement design. Ms. Ash conducted multiple hydraulic analyses using U.S. Army Corps of Engineers HEC-RAS software. Analyses included determination of bankf ill discharge using field indicators of bankfull stage, quantification of predicted improvements to shear stress, stream power, and velocity as a result of proposed restoration activities, verification of floodwater surface elevations, and shear stress -limited evaluation of bioengineered bank treatments. Ms. Ash also conducted a geomorphic analysis using regime equations and hydraulic geometry relationships to determine stable channel characteristics for specific stream types. In addition to the channel work, comprehensive riparian corridor restoration was a major component of the restoration project. Ms. Ash provided estimated flow depths for the low flow (or sustaining flow) using the HEC-RAS models to help guide plant zonation for the revegetation efforts. CACHE LA POUDRE RIVER REMOVAL ACTION, FORT COLLINS, CO Mr. Gurned led negotiations regarding riverine, riparian and wetland regulatory and restoration standards on behalf of the City of Fort Collins ROARING FORK GOLF & FISHING CLUB, BASALT, CO Mr. Gumed provided the assessment, design, permitting and construction supervision of a native trout stream (1 mile) with associated wetland complexes (3 acres). The trout stream was created as an amenity and functional fly-fishing challenge for this golf/fishing club (Jack Nicklaus designed course); and the associated wetland and riparian habitat were created to naturalize the stream and provide compensatory mitigation for impacts associated with the development of the club facilities. TOBACCO ISLAND PROJECT, KANSAS CITY, MO Mr. Gurne6 prepared an Environmental Impact Statement for the Army Corps of Engineers, Tobacco Island Project - a portion of the Missouri River Bank Stabilization and Navigation, Fish and Wildlife Mitigation Project. MASTER PLANNING THE SAN MIGUEL RIVER CORRIDOR RESTORATION PLAN Mr. Gurnee was lead planner of the San Miguel River Corridor Restoration Plan and assisted the Town of Telluride in applying for and winning approximately $500,000 in Natural Resource Damage Assessment Fund money from the State of Colorado.

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. 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. 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. The audit scope and objectives must be defined as early in the project as possible. The regulatory programs to be included in the audit must be identified. These programs may include hazardous waste (RCRA), air emissions (CAA), wastewater and stormwater (CWA), community right -to -know (EPCRA), worker health and safety (OSHA, MSHA), and others. We 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 be 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 1 audit activities. • 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. 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 also performed risk assessments for Alliant TechSystems (where a human health risk assessment formed the basis for closure of a chlorinated solvent site in Denver) and CDOT. 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 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 For the BLM, Walsh used a risk -based approach to evaluate remedial alternatives at the Saginaw Hill Mining District in Tucson, Arizona. There, metals -impacted soils and mine tailings are in an area currently occupied by and adjacent to rural housing and schools on the edge of Tucson. Walsh also recently conducted a screening level human health risk assessment for an oil company operating oilfields in the country of Yemen. The potential for areas of petroleum -contaminated soils to impact the health of workers and residents was evaluated, for both the dermal contact and groundwater/drinking water pathways. 1.B.7 Alr Pennilting, Monitoring, Modeling and Compliance Dr. Arthur Mizzi of Walsh will be responsible for the air quality issues of this project. Dr. Mizzi is a Certified Consulting Meteorologist and an environmental attorney whose expertise includes air quality compliance counseling, applied atmospheric modeling, model development, air quality assessments, and permitting under PSD and non -attainment NSR programs. a. Develop and prepare air permits. Various City departments operate various facilities and/or equipment that are potential sources of air pollution that 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. Walsh 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.

He has performed investigations and cleanups under multiple state and federal programs including LUST Trust, VCUP, CERCLA (Superfund), RCRA, TSCA and NEPA. 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. PROJECT EXPERIENCE CAPTAIN .LACK SUPERFUND SITE Mr. Spencer is currently the Remedial Investigation (RI) project manager at the Captain Jack Mill (CJM) Superfund Site, in Boulder County, Colorado. The site was listed on the National Priorities List (NPL) on September 29, 2003. The purpose of the RI is to determine the nature and extent of contamination associated with former mining and milling operations, and to develop remedial alternatives that can be evaluated to support a Record of Decision (ROD). The investigation comprises a broad -based, multi- media sampling program including surface and ground water, soils, mine waste and biota. All work is under approval by CDPHE and EPA and subject to stakeholder review by Left Hand Watershed Oversight Group and Boulder County Health in addition to the public. The CJM Superfund site is located near Ward, Colorado, within the Left Hand Creek Watershed. In the 1980s, the Environmental Protection Agency (EPA) discovered fisheries and wetlands impacts in the Watershed. These impacts were suspected to be associated with discharges of metal -contaminated water from the major abandoned mining and milling areas, including the CJM site (Left Hand Watershed 2004). Subsequent evaluations by the Left Hand Watershed Task Force and Boulder County Health Department (BCHD) identified potential risks to the Watershed by abandoned mines, and concluded that a systematic study of the entire Watershed was needed. rn oroposaldsWort collins\07 env semces rebid\fort collins resumes\spencerWdoc Stanley C.

LLC former fuel storage facilities at the Creamery Building and at the Total Petroleum site at 741 North College For construction sites owned by the City, Walsh has performed reviews of sampling plans, workplans, and corrective action plans relating to on -site residual petroleum contamination. Walsh has been proactive in advising City personnel on a variety of pending regulations prior to being put into effect, including new Phase I ESA standards and ACS regulations. Advising the City on Proper Waste Disposal. Walsh advised the City on disposal of wastes from abandoned sludge digestors at the Mulberry Treatment Plant, abandoned wastes at Parks and Natural Areas facilities, drummed wastes at the Wastewater Treatment Plant, disposal of routine lead waste from Police Firing Range operations and as part of a lead reduction operation at the range, street sweeping wastes, and storm debris. Walsh routinely provides recommendations in technical reports of required and available disposal options for wastes. Walsh has coordinated investigation derived waste (IDW) characterization and disposal activities on all Phase 11 site investigation projects completed for the City. Advising the City on Waste Reduction and Pollution Prevention. Walsh analyzed and evaluated wastes produced by parts washers at City facilities, and recommended the technology which had the least adverse effect on the environment. Walsh also provided a comprehensive SPCC plan training program. Wastes from selected City properties have been managed through Larimer County's Business Hazardous Waste Assistance and Education Program (BHAPE) to reduce overall disposal costs, and to promote re -use and/or recycling. Voluntary Cleanup and Brownfields. Walsh has prepared a VCUP application for a No Action Determination (NAD) for the Former Municipal Landfill located along the banks of the Cache La Poudre River in the Downtown Corridor. This NAD request has been approved by CDPHE representatives. Walsh has also reviewed a VC UP application related to the Timberline Road Widening project and provided comments and recommendations to City staff. Walsh also performed oversight on a voluntary cleanup at Block 33 for the City. Walsh performed a preliminary assessment of the Downtown River Corridor, and assisted the City in obtaining a $250,000 grant from the U.S. EPA for assessment services. Walsh performed Phase I ESA and Phase It site investigations under this grant. Remediation and UST Closure Services. Walsh provided services for removal and closure of hydraulic lifts and waste oil tanks, monitor well installation, and ground water monitoring at the Fleet Services facility. Walsh performed oversight services during contaminated soil remediation work at the Bartran property and a site located near Timnath, Colorado. Ecological Assessment and Permitting. Walsh assisted the City with the river restoration aspects of the Cache La Poudre River cleanup project by providing staff to act as a liaison throughout the project, from the initial negotiation of restoration requirements through the construction process and the negotiation of maintenance and monitoring requirements. Walsh has been retained by the City to prepare an Ecological Characterization Study for the proposed watercraft course adjacent to the old Power Plant. The study will be prepared in coordination with City staff and pursuant to the City of Fort Collins, Division 3.4 Environmental, Natural Area, Recreational and Cultural Resource Protection Standards. Walsh also provided wetland assessment and permitting services to the City at the SouthRidge golf course site. Waste Inspection and Analysis. Walsh staff completed abandoned drum sampling and characterization activities at the Hazaleus property and provided disposal coordination support and oversight during subsequent over packing and removal of liquid wastes. For the Parks Department, Walsh characterized numerous containers of abandoned wastes and made recommendations for disposal. For the Streets Department, Walsh analyzed sweeping debris generated by street cleaners, identified potential regulatory issues surrounding such waste, and made recommendations for disposal. In addition, Walsh provided sampling, analysis, and interpretation for parts washer residue at the Transfort and Fleet Services facilities. Page B-2 Walsh ErMrenmental Scientists and E.nginecrs. LLC. v cp, River Point at Sheridan Brownfield Redevelopment, Sheridan, Colorado Walsh is currently partnering with developer Miller Weingarten to complete environmental tasks for the construction of River Point at Sheridan, a $150MM, 130-acre retail center in the south Denver metropolitan area. This brownfield redevelopment site is situated on two historic landfills including the Arapco Landfill and Herbertson's Pay Dump. Primary environmental hazards include high concentrations of landfill gasses that migrate through the waste and along existing utility corridors. Additional concerns include soil and groundwater contamination from both on -site and upgradient sources. Thirty five buildings were present on 55 properties at the site. The redevelopment also includes the Platte River, and part of the Englewood municipal golf course. Regulatory Negotiations and Approvals. This highly complex project required extensive and creative negotiations between the developer, the City of Sheridan, the State regulatory authority (Colorado Department of Public Health and Environment), the Tri-County Health Department, and others. From the onset of the project, it was known that full removal of the landfill waste would drive the developer from the table. Though estimates varied, full removal of the waste would be in excess of $100 The Sheridan Redevelopment Area, a complex site, has remediation of both industrial properties and former landfills that were under the Englewood Golf Course. Numerous boreholes and trenches were excavated during the Phase II ESA, as shown by colored dots on this aerial photograph of pre-existing conditions. Million. As a result, strategic removal of the waste was proposed; five feet of waste was removed from the parking lots, while all of the waste was removed from beneath some buildings and none of the waste was removed from beneath others. Specifically, the remedial alternative was tailored to the construction requirements. However, one characteristic is the same for all buildings — an active vapor mitigation system. Walsh developed state-of-the-art vapor mitigation design criteria to help guide the construction of the vapor mitigation systems. Walsh worked in concert with the regulatory agencies and the owner to come up with remedies that are protective of human health and the environment, as well as support redevelopment of a very complex site.

H.C. requirements, as well as periodically provide monitoring and compliance reports to APCD. Walsh 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. Walsh 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. Walsh can also address visibility and haze issues and greenhouse gases in special reports, including possible support from the trained emissions auditors of E&E. 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 (MACT) and updates to new source permitting regulations. Walsh 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. Walsh can assist the City in commenting on APCD's permit actions for industrial sources impacting the City. All new and modified APCD permits are subject to a 30-day public comment period and the City may offer comments on these permits in cases where there is concern over the impact of these emissions on City residents. Walsh can assist the City review and provide comment on APCD permit actions (except in cases where we represent the permit applicant). d. Advise and assist in the development or review of risk management plans for responding to the accidental release of regulated substances. -and- e. Prepare air hazard assessment regarding release scenarios, zones of impact, identification of impacted receptors. Subtasks d and e 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. Walsh can assist the City in compliance 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. Walsh can review and compile data from existing RMPs and ensure that all hazard modeling was prepared on a consistent basis. Fort Collins Env Services 2007 v8 Page 25 Z. Walsh Environmental Scientists and Engineers. LLL' Creek. As part of the redevelopment, the Platte River channel and the confluence area are being stabilized to minimize erosion into landfill areas and the golf course. In addition, restoration of the channel area is being undertaken to improve wildlife ha designs for armoring and stabilizing the river channel, and reclamation/planting plans to enhance the natural habitat areas of the golf course. An innovative part of the design is the creation of an engineered swale to convey stormwater and minimize sediment runoff into the Platte River to improve water quality. Walsh also designed nature trails and other amenities. Walsh conducted assessments and evaluations of wetlands, Threatened and Endangered Species, and migratory birds. Walsh also worked with the developer to obtain a grant from the Colorado Governor's office for streambank stabilization. Walsh created designs for restoration and Planting Plans to Mitigate Methane Impacts. stabilization of the Platte River and Bear Creek Because much of the landscaped area of the (shown here). development will be over undisturbed landfill materials, methane gas will be present in soils at low concentrations. The developers were concerned that trees, shrubs, and grasses planted during landscaping would die from exposure to the methane. Plans had been drawn up for planting trees and shrubs in methane -free buried concrete "bathtubs". Recognizing the potential costs, Walsh botanists evaluated a variety of plants for methane tolerance, and created a planting plan that included methane -resistant plant taxa. This negated the requirement for special planting areas, saving about $1.5MM in engineering costs. Construction Monitoring and Oversight. The first phase of the project requires removing a substantial amount of this waste to provide a sound subsurface for constructing roads, utilities and buildings. While it is likely the contents are mostly municipal solid waste, there is the potential some hazardous waste, storage tanks and contaminants may be encountered during the excavation process. In accordance with the agreements with the CDPHE Walsh is providing inspectors at the points of excavation. Each inspector is a certified asbestos inspector and trained in taking opacity readings. Additionally, some inspectors are certified by the State for odor monitoring. The goal is to minimize the potential for hazardous waste inadvertently being loaded into trucks and delivered to the landfill. Walsh has worked closely with the State and with the disposal facility to protect against the delivery of drums, asbestos, transformers, pressure vessels or any other kind of "special" or hazardous waste. At the completion of the project, Walsh will certify that the excavation activities were completed in accordance with the State regulations. This provides risk management to the owner and also serves to initiate specific insurance policies. Page B-16 Walsh Environmental Scientists and Engineers.

Walsh has had multiple task awards under the contract since 1988 with an average of approximately $400,000- $500,000 in tasks completed per year. Walsh has assessed 90 tank sites, monitored about 70 sites, removed USTs from 6 sites, and designed 5 active remediation systems, all of which included plans and specifications, construction oversight, and O&M tasks. Burlington Mine Remediation and Reclamation under VCRA Jamestown CO: At an abandoned fluorite mine near Jamestown, Colorado, Walsh plugged collapse features, closing adits and shafts, relocating a stream, and built and reclaimed a mine waste rock repository. This 13-acre facility contained over 10,000 feet of underground tunnels, adits and shafts. Acid mine drainage was discharging into Little James Creek, which is used for drinking water by downstream communities. We submitted a voluntary cleanup plan to the Colorado CDPHE. A major part of this project involved diversion of the existing ephemeral stream around the mine workings to minimize the amount of surface water that comes into contact with the waste rock. The reclamation included plugging the subsidence pits, blocking the alluvial and surface flow of the captured stream and permanently diverting it around the underground workings, consolidating the mine waste piles into a repository, and revegetating the entire site. Inspections/Oversight and Phase I and II ESAs for Demolition of 14 Buildings - Obermeyer Redevelopment Project: Walsh provided environmental consulting services for Szymanski - Ray and Obermeyer Redevelopment Corporation for the redevelopment of a city block in Aspen containing 14 commercial and residential structures. Walsh provided a significant level of coordination and communication with the owner and the 28 separate tenants that vacated the buildings during the project. At the Obermeyer Place Redevelopment project in Aspen, Walsh's Phase II ESA identified lead and other metals in soils from a former assay office and mine tailings dumps. Walsh treated 10,000 cubic yards of soils, and disposed of the most contaminated portion in a landfill (after ensuring that the landfill acceptance criteria were met). The clean portion was used as road base at a nearby road construction project. Fort Collins Env Services 2007 vN Page 28 Walsh 77ironinental Scientists and Engineers, LLC During and after the demolition phase, Walsh conducted a Phase II ESA that determined the presence of lead and other heavy metals in soils beneath the buildings. These came from a former mineral assay office on the property, as well as mine tailings that had been disposed of on the property. Walsh characterized and segregated the tailings, and treated over 10,000 cubic yards of contaminated soils. Further information is provided in Appendix B. >.C.3 Eco%gica/Assessment and Permitting[ Projects Cache la Poudre River Restoration Desien and Construction Assistance: Walsh assisted the City with the river restoration aspects of the Cache la Poudre River cleanup project. Walsh provided specialized expertise in river restoration design, bioengineered bank stabilization measures, instream habitat enhancement, and riparian corridor restoration. During the construction phase, Walsh assisted the City with oversight of the restoration and landscape contractors, recommendations for specific construction methods, and assistance with logistics. We provided construction oversight during all phases of the project. Walsh was also requested to provide negotiation, design review, and construction oversight assistance for the North Weld County Water District (NWCWD) Water Line Crossing Area. Ecological Characterization Study for Watercraft Course on the Poudre River: Walsh has been retained by the City of Fort Collins to prepare an Ecological Characterization Study for the proposed watercraft course adjacent to the old Power Plant. The Ecological Characterization Study will address wildlife use of the area, wetlands in the area, prominent views from or across the site, inventory of native trees, identification of wildlife movement corridors, and other features. Edwards Eagle River Restoration Project: Walsh is currently providing grant funding support, assessment and design services to the Eagle River Watershed Council for the Edwards Eagle River Restoration Project. The Project site is roughly 1.5 miles long covering an area of 168 acres in the heart of the Edwards community. Restoration, enhancement and protection is proposed on both north and south banks, in the stream channel, as well as within the floodplain. In addition to direct river improvements, the project will reduce current land use impacts throughout the corridor, improving bank conditions and water quality for the river. City of Longmont Wildlife Management Plan: For the City of Longmont, Walsh completed the development of a Citywide Wildlife Management Plan for the Parks and Open Space Division of the Department of Community Development. The plan addressed management requirements of "regulatory" species, "biodiversity" species, and "problem" wildlife. The plan also presented a method for prioritizing future land acquisition and management specifically to preserve wildlife and made recommendations for strengthening and broadening the City's existing land development code. Community Wildfire Protection Plans (CWPPs), Jefferson County Colorado: Walsh is developing CWPPs for nine fire protection districts in the wildland-urban interface (WUI) portions of Jefferson County. Jefferson County's WUI is characterized with steep slopes, overgrown mixed -conifer forests, oak and mountain mahogany stands, and grass fields. Wildfire risks and hazards were identified through community and fuel assessments, interviews with fire officials, community officials, and a questionnaire mailed to residents. Public meetings were convened to discuss wildfire risks, wildfire hazards, and mitigation opportunities. We assessed fire protection district wildfire preparedness, training, and needs. Buckley Air Force Base Wildland Fire Management Plan Colorado: Walsh developed a Draft Wildland Fire Management Plan for Buckley Air Force Base, Colorado. The Plan considered existing conditions, wildland fire history, values at risk, wildland fire fighting resources and training, and environmental conditions and fire effects to develop practices for pre -suppression actions, fire suppression actions, post -fire actions, and fire management areas. We also described the procedures needed to introduce prescribed fire as a shortgrass prairie and fuels management tool. Fort Collins Env Services 2007 v8 Page 29 s Walsh. Environmental Scientists and Engineers, LLC Ecological Services for the City of Loveland, Larimer County: Walsh has supported the Larimer County Fairground Renovation Project for the City of Loveland. Walsh ecologists consulted with the US Fish and Wildlife Service (USFWS) concerning the potential occurrence of Preble's meadow jumping mouse on the site. This resulted in an accepted site disqualification report for this species. Walsh is also supporting the required 404 permitting for the project. This has included a wetland delineation of the site, consultation with project designers, and submission of a permit verification to the Army Corps of Engineers (COE). f.C.4 Voluntary Cleanup Voluntary Cleanup and Brownfields Programs for the City of Fort Collins: Walsh has prepared an Application under Colorado's VCRA program for a No Action Determination (NAD) for the Former Municipal Landfill along the banks of the Cache La Poudre River in the Downtown Corridor. The VCUP application concisely summarized historic site investigation data generated by a multitude of environmental consultants. This NAD request was recently approved by CDPHE representatives. Work completed under an EPA Brownfields grant has helped the City of Fort Collins redevelop the underutilized downtown river corridor.

LLC 2.B.8 Air Permitting, Monitoring, Modeling and Compliance Staff Arthur Mizzi, Ph.D., J.D., CCM: Scientist/Attorney, Boulder Arthur Mizzi is the head of Walsh's Air Quality Practice Group and will lead air permitting, monitoring, modeling, and compliance tasks. Dr. Mizzi has over twenty-five years of related experience. He studied meteorology, with an emphasis in atmospheric modeling, and worked as an Associate Scientist and the National Center for Atmospheric Research (NCAR) in Boulder. While at NCAR, Dr. Mizzi's research focused on the development of atmospheric models. Dr. Mizzi graduated from law school in 1997; from 1997 to 2005, Dr. Mizzi worked at various private environmental law firms in the Denver area. During that time, he prepared emission permit applications, provided compliance counseling, provided advice on existing, pending, and potential air quality laws and/or regulations, and reviewed and supervised emission modeling for permitting and litigation. The clients he worked with included a municipality and its international hub airport, a computer chip manufacturer, an oil and gas developer, a printing company, an aggregate company, an insulation manufacturer, a coal-fired power facility, and an aerial spray applicator. Dr. Mizzi has (i) provided emissions permitting support for a coal-fired power facility in the Pacific Northwest and for a paperboard manufacturer in the Southeastern U.S.; (ii) used emissions modeling to provide litigation support for a west coast coal fired power facility, to assess potential odor impacts from a sewage treatment facility, to assess human health risks associated with hazardous air pollutants emitted from an air sparging operation, and to assess emission sources of soil contaminants; and (iii) provided compliance counseling on various air quality issues for a municipal electric power facility. Dr. Mizzi will work closely with the City to (i) develop and prepare air permits, (ii) supervise subcontractors that will perform any required air monitoring, (iii) conduct record keeping and prepare all routine or special reports associated with the monitoring or as required by the regulatory agencies, (iv) provide advice on the import of existing, pending, or potential federal, state, regional, or local air quality laws and/or regulations, (v) perform modeling in support of permit applications or hazard assessment, and (vi) assist with development of risk management plans. 2.B.9 Additional Personnel In addition to these Key Personnel, Walsh has a deep pool of experienced personnel from which to draw for additional project support and expertise.

LLC 3. Proposal Section Three: Fees and Costs IA General Labor and Direct Costs Walsh is aware of the importance of cost control to the City, and we are experienced in cost -control measures for similar general environmental service contracts. Walsh is offering the services of its Program Manager, Dr. Hal Stuber, at a rate of $115.00/hour, a substantial reduction from both his standard rate ($150.00/hr) and competitive rates for comparable qualifications and expertise. This cost savings on Dr. Stuber's hourly rate continues a commitment Walsh 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, with only minimal incremental raises, during the last 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. 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 Environmental Services Contract. The following sections detail our personnel and significant other direct costs.

Per sample costs will be affected by matrix type, activity levels, sample numbers, tests, QC criteria, deliverables, period of performance, TAT, or other project specific requirements. Please note that disposal charges and sample minimums may affect total costs. Paragon must be contacted and authorization must be provided prior to any sample shipments. Final per sample costs and any additional applicable fees (Rush TAT surcharges, Small Batch surcharges, Reporting surcharges, Matrix surcharges, etc.) will be negotiated with the client prior to shipments. Sample Minimums Please note that Paragon has instituted a small batch surcharge policy. Batch sizes of less than three samples will incur the greater of a $250 minimum, or a 3x multiplier per test per matrix QC charge, due to method QC requirements for blanks, MS/MSDs and LCS/LCSDs. This surcharge is determined on a case by case basis and can be waived except in expedited turnaround time cases. Sampling Kits and Shipping Costs include complete sampling kits shipped via second -day economy to your location. Sample kits must be ordered not less than 5 business days prior to delivery to avoid shipping charges being billed to your account. These kits include sample containers and preservatives, chain of custody documents, labels, coolers and packing material. Unreturned coolers and bottles may be billed at cost plus handling charges unless approved in advance. Client bears financial responsibility for shipping samples to the laboratory. 2006 Paragon Price List - Page 9 of 12 PARAGON ANAL YT/CS PARAMETER MATRIX METHOD Per Sample Minimum Volume Container Preservative Holding Time Cost TAT Type Paragon must be notified prior to sample shipments. Reporting Prices quoted are for a Level II report and includes method blank, LCS and duplicates as applicable. Paragon's standard EDD is available as flat files created from a relational database. File format is ASCII text, compatible with Excel. Analytical Assumptions Analyses performed in strict accordance with SOPs based on approved methodology. Our standard analyte lists and reporting limits will be provided. Matrix, solubility, sample volume, percent solids and activity levels may affect reporting limits. Paragon's historical intralaboratory QC limits will be utilized. Unit costs include laboratory QC where applicable at 5%. Field QC such as trip blanks, field duplicates, and rinseates are billable. MS/MSDs where applicable may be billable. Unit costs do not include clean ups and special preparations such as florisil, silica gel and gel -permeation. Concrete must be received in pieces < .25 inches to avoid offsite subcontractor size reduction charges. Paragon will perform and report on the dilution that brings the highest analyte into the upper half of the linear calibration range. Re -extractions or dilutions will be performed at your request at an additional charge. 2006 Paragon Price List - Page 10 of 12 PARAGON ANAL YT/CS PARAMETER MATRIX METHOD Per Sample Minimum Volume Container Preservative Holding Time Cost TAT Type For method 5035, Paragon will freeze samples thereby allowing a 14 day hold time to be utilized. Unit costs do not include EnCore@ samplers. Re -preps or re -analyses performed for radiological procedures due to matrix interferences will incur a difficult matrix surcharge of 50%. Client will be contacted prior to initiation of re -work that would fall under the difficult matrix surcharge. Radium 226/228 by gamma spec is method constrained to a 30 day turnaround time to allow for —99% ingrowth of the Radon-222 and Pb/Bi-214 daughters used for the determination. When Ra-226 is requested to be reported by GFP method 903.0: At the discretion of the laboratory, the samples may be counted prior to the requested decay period (typically 14 or 21 days). If the results are less than the requested MDC, they will be reported with an appropriate narrative comment, without further qualification. Handlinu of Radioactive Samples Paragon understands that no radioactivity above background is anticipated. Potentially radioactive samples will require an additional day of turnaround time for screening. Prescreening data provided by the client must be approved by the lab prior to sample acceptance. Our radioactive license allows Paragon to accept up to 10 mCi Alpha, IOmCi Beta, 50 mCi H3 and 1 mCi source material. Samples will incur a 25% Health and Safety surcharge for: alpha >1nCi/l or 0.5 nCi/g, beta/gamma > 2 nCi/l or 1 nCi/g, or tritium > 100 nCi/l or 1nCi/g. Samples with activities exceeding 1000pCi/G or L gamma will be quoted on a case by case basis. Sample Disposal Samples and process wastes will be disposed of gratis unless: they are both radioactive and contain TSCA or RCRA wastes, contain high level waste as defined in 1 OCFR60.2 or contain enriched uranium in excess of 2000 pCi/g. Samples and wastes in those classifications will be returned to the client at 2006 Paragon Price List - Page 11 of 12 ZI Walsh vironmental Scientists and Engineers. LLC Walsh's program manager for Fort Collins, Hal Stuber, has a doctorate in environmental chemistry, 25 years of professional experience, and is one of the founders of Walsh. He has served as Program Manager under the City's General Environmental Services Contract since 1997. As part of our commitment to a long-term relationship with the City, Walsh has provided Dr. Stuber's professional services to the City at rates that are discounted from his normal rates, and we offer to continue that practice in the future. Walsh estimates that these discounted rates have saved the City more than $30,000 in the last five-year term of our contract (2002-2007) with Fort Collins. 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 perform Phase I Environmental Site Assessments. However, Walsh offers extensive 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 city's roles as both owner and acquirer of properties that are subject to liability and regulation, and its many roles in planning, development, and construction. Walsh has demonstrated that it can provide outstanding technical services, and perform pioneering work in environmental assessment and remediation. Examples include Walsh's pioneering work in the discovery, characterization, assessment of health risk, and remediation of indoor air impacts arising from ground water contamination. Our work on indoor air at the Colorado Department of Transportation (CDOT) Headquarters site in the Denver metropolitan area is recognized as the first major project of its kind. The scientific and engineering expertise we gained on that project has helped the City identify and address the potential concerns for the City's new Northside Community Center. For the City of Louisville, Walsh is conducting Phase I and I I ESAs for the redevelopment of land adjacent to the proposed FasTracks commuter rail station. This project is being funded by an EPA Brownfields Grant. We are up-to-date on regulatory developments that could affect the City. For example, we worked extensively on behalf of the Fitzsimons Redevelopment Authority (FRA) to collaborate with CDPHE to create protocols for investigating and remediating asbestos in soils at the Fitzsimons site. These protocols were subsequently adopted by CDPHE into new state-wide regulations governing the handling of asbestos in soils. Part of our ability to stay at the leading edge of environmental and regulatory developments derives from our work on important projects. Dr. Hal Stuber is also Program Manager for Walsh's contract to provide Environmental Services for the Regional Transportation District's (RTDs) FasTracks Program. RTD's FasTracks Program is a $4.5 billion program to construct and operate 9 rapid transit corridors, including 119 miles of light and commuter rail transit, scheduled for completion in 2016-17. This project will require efficient, state-of-the-art site assessment, remedial action, and data management efforts over an extended period. Walsh believes our ongoing experience in this major public project will be of significant benefit to the City of Fort Collins.

LLC 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. One example of the capabilities, commitment and continuity that Walsh offers to the City is our record of working with the City staff on the Aztlan Site. In the 1990s, Walsh helped the City win an EPA Brownfields Grant of $250,000 for assessment in the Poudre River Corridor. While working under that Environmental Protection Agency (EPA) grant in September, 2002, Walsh staff members discovered and characterized coal tar releases to the Poudre River. Following that discovery, Walsh provided continuous, comprehensive technical support to the City through the multi -year process of helping to identify the source and responsible parties, and the review, evaluation, planning, construction, regulatory agency relations, and monitoring of an approximately $17 million remedial action completed on City property by the responsible parties. An example of a different kind of commitment to the City of Fort Collins is Walsh's support of the Poudre Landmarks Foundation efforts to restore and present to the public the historic Romero House, the first adobe house in Fort Collins. In 2002, Walsh was approached by Margit Hentschel of the City's Natural Resources Department, who inquired if we could assist the Poudre Landmarks Foundation efforts. When Walsh learned that the City had no funds to offer, we offered to provide asbestos and lead paint inspections services (pro-bono) on this worthy project. Walsh is proud to have been a part of this effort, and that the historic Romero House is now accessible to the public. About Walsh. Walsh is a multidisciplinary environmental services firm founded (1979) and headquartered in Colorado. Walsh offers expertise in all phases of environmental site assessments, contaminant investigations, remedial design and construction, ecological assessment and restoration, air quality investigations and permitting, human and ecological risk assessment, auditing, modeling and compliance.

Ash, P.E. Paee 2 Ms. Ash has provided technical services in construction/environmental testing as a materials laboratory technician for an analytical laboratory. Experience includes water quality checks, soil boring documentation, magnetometer surveys, particle size analyses, Atterberg limits determinations, and triaxial permeability testing for numerous projects, including a landfill construction project. KEY PROJECTS EXPERT WITNESS PROJECTS GRADING AND DRAINAGE ISSUES FOR PARKING LOT DISPUTE, STEAMBOAT SPRINGS, COLORADO Provided expert opinion and testimony on grading and drainage issues related to a dispute over water damage to a parking lot. Based on document review and site visits, testimony covered potential sources of water to the site, historic drainage patterns and disturbances, and continuous flow vs. stormwater runoff events. STREAM RESTORATION & CHANNEL IMPROVEMENT PROJECTS LEACH CREEK STREAM CORRIDOR ENHANCEMENT, GRAND .JUNCTION, COLORADO Ms. Ash designed stream corridor enhancements for a channelized section of Leach Creek. Enhancements were designed to restore natural channel form and function, improve the aquatic environment, and provide mitigation for jurisdictional impacts permitted under the Nationwide Permit program. Proposed enhancements included channel realignment to improve sinuosity, creation of appropriate channel geometry including bank layback and low overflow benches, bank protection treatments, and restoration of native vegetation for riparian habitat. The restoration of bankfull sinuosity allowed the channel to perform natural functions of local scour and deposition, dissipating energy in the appropriate manner for low gradient fluvial systems. The low overflow benches provided greater flood attenuation, groundwater recharge, nutrient replenishment, and they substantially improved the natural aesthetic for the corridor. The native revegetation restored the corridor's overhead cover functions, providing shading and cooling, as well as a detritus source for the system. The restored root matrix helped stabilize eroding channel banks. The project also included coordination for mitigation compensation on another project located nearby. GYPSUM CREEK FISHERIES ENHANCEMENT, GYPSUM, COLORADO Aquatic habitat improvements along Gypsum Creek included both instream and bankside treatments. Instream treatments served to improve deepwater habitat, create flow separation or concentration zones, increase low flow sinuosity, provide instream cover, improve adult fish habitat, create nursery areas, and enhance spawning opportunities. Bankside treatments for aquatic habitat improvements included creation or enhancement of overhead cover, provision of protective cover and enhancing shading, cooling, and nutrient cycling functions. Bank protection treatments served to correct localized bank instabilities and reduce bank erosion and the potential for sediment deposition downstream. Because the Gypsum Creek corridor was in very good condition initially, the enhancement work was designed following a "don't do more harm than good" philosophy. Only low intensity, low impact treatments were utilized. Only small, rubber -tired construction equipment was allowed onsite and only in specified reaches where established microhabitats would not be affected. Equipment was not allowed to "drive" the channel. Work was conducted by hand in all areas that were inaccessible by equipment. INSTREAM HABITAT STUDY FOR THE NORTH FORK, BOSS, AND O'HAVER IFIM ANALYSES, SAN ISABEL NATIONAL FOREST Ms. Ash conducted an instream flow study to analyze different flow management scenarios for rainbow, cutthroat, brook, and brown trout habitat and riparian vegetation in streams affected by storage of water in North Fork, Boss, and O'Haver Lakes. The study was in support of United States Forest Service (USFS), San Isabel National Forest evaluation of potential changes in aquatic habitat below North Fork, Boss, and O'Haver Reservoirs resulting from hydrologic operations at each dam. The evaluation was conducted as a component of an Environmental Impact Statement (EIS) addressing re -permitting of each reservoir. The Julie E. Ash, P.E. improvements to help prevent the reformation of rills and other erosive features after the restoration work. The analysis also determined the maximum acreage that could be returned to natural drainage patterns without threatening the stability of the receiving tributary below. Ms. Ash provided design details, developed site maps, performed earthwork calculations, conducted calculations for channel sizing and instream structure design, provided materials quantifications, and provided assistance for technical notes and construction oversight. HYDRAULIC CAPACITY ANALYSIS FOR JURISDICTION DETERMINATION AT CARTER LAKE Conducted hydrologic and hydraulic analyses for the drainage located below a proposed reservoir to evaluate overland flow connection for U.S. Army Corps of Engineers (USACE) jurisdiction determination. She helped USACE develop quantitative approach and scientific basis for field application of current regulations regarding "isolated waters of the U.S." STREAM AND FLOODPLAIN RESTORATION AT COAL MINING FACILITY, KENTUCKY Member of technical design team tasked with assessment and restoration of 26 miles of stream corridor following the accidental release of 250 million gallons of coal slurry into two separate drainages in eastern Kentucky. Several local drainages, unaffected by the release, were employed as reference reaches to guide channel rehabilitation and habitat improvement design. Ms. Ash conducted multiple hydraulic analyses using U.S. Army Corps of Engineers HEC-RAS software. Analyses included determination of bankfull discharge using field indicators of bankfull stage, quantification of predicted improvements to shear stress, stream power, and velocity as a result of proposed restoration activities, verification of floodwater surface elevations, and shear stress -limited evaluation of bioengineered bank treatments. Ms. Ash also conducted a geomorphic analysis using regime equations and hydraulic geometry relationships to determine stable channel characteristics for specific stream types. In addition to the channel work, comprehensive riparian corridor restoration was a major component of the restoration project. Ms. Ash provided estimated flow depths for the low flow (or sustaining flow) using the HEC-RAS models to help guide plant zonation for the revegetation efforts. STREAM CHANNEL CREATION TO SUPPORT WETLAND MITIGATION, COLORADO SPRINGS, COLORADO Conducted water budget calculations and performed hydrologic analyses using Soil Conservation Service TR-55 methods for a 2.5-acre streamside wetland area and the meandering stream channel that supports it. Natural channel design imitated natural prairie drainages and included a mild gradient, a high level of sinuosity, a wide floodplain, and vegetated channel bottoms. Ms. Ash developed stable channel conditions using regime relationships for geomorphic characteristics. Meander geometry formulas were used to establish the channel's geomorphology, including meander wavelength, amplitude, and radius of curvature. MOUNTAIN STREAM CORRIDOR RESTORATION, TELLURIDE, COLORADO Managed river corridor restoration project from field assessments through design and construction. Technical design team completed design with components including re-establishment of stable channel slope and geometry, channel realignment to natural sinuous plan form, low flow concentration and creation of deepwater pools and riffles for aquatic habitat, reduction of runoff -induced situation, improvement of bridge hydraulics, management of the upstream sediment supply, wetland creation, and revegetation of the riparian corridor. Ms. Ash provided construction oversight for the project with support services including site layout, survey checks, onsite guidance for design plan implementation, environmental compliance assistance, field modifications, and general operations support. CHANNEL IMPROVEMENTS AT CITY NATURAL AREA, DENVER, COLORADO Member of technical design team and construction supervisor for channel stabilization and habitat improvement project through a City of Denver natural area. Design components utilized combinations of traditional and bioengineering techniques to enhance habitat value while accommodating high -risk conditions in the urban setting and included drop structures for slope reduction, low flow and flood channels, bank stabilization, shortgrass prairie restoration. Ms. Ash obtained the Section 404 permit for the project and designed a wetland mitigation area as compensation for unavoidable wetland impacts. Julie E. Ash, P.E. Ms. Ash also provided construction oversight for the project. Construction support services included cost estimating, site layout, survey checks, onsite guidance for design plan implementation, and environmental compliance assistance, and troubleshooting and field modifications. RIVER CORRIDOR RESTORATION AT PRIVATE RANCH, KREMMLING, COLORADO Designed and supervised construction of a project on a private ranch to restore a historic side channel of the Colorado River, which had been dammed into three elongated, stagnant ponds. Design components included creation of deepwater pools and riffles for aquatic habitat, a fish nursery area, wetland creation, and development of a riparian corridor. Ms. Ash performed hydraulic calculations to predict backwater conditions and determine instream structure spacing. Ms. Ash also provided construction oversight for the project, including site layout and survey checks. WETLAND MITIGATION & SHORELINE STABILIZATION PROJECTS CREATION OF WETLAND SWALE, COLORADO SPRINGS, COLORADO Completed the design and construction drawings for creation of an approximately 2-acre wetland mitigation project. Project components included creation of low earthen check structures to retain water delivered from an existing storm water system. The check structures route water to a small pond at the lower end of the wetland. Spreader ditches, along with shallow excavation within the swale, maximized the wetted area within the Swale. Habitat diversity was promoted by clustering native tree and shrub species in drier areas and planting a mix of native herbaceous species in wetter zones. SHORELINE STABILIZATION AT REMNANT GRAVEL POND, BOULDER COUNTY, COLORADO Developed a shoreline stabilization plan for the wave -battered eastern shoreline of a gravel pond with habitat enhancement features for shallow and deepwater fish habitat in the pond. Design included a variety of protective "bank logs" with innovative placement to create a more natural, undulating shoreline. The naturalized shoreline provided aesthetic improvement and encouraged development of more diverse microhabitats, such as small pocket pools and localized shade zones. Willow installations restored the stabilizing root mass that previously protected the shoreline. Protection of the new shoreline vegetation was accomplished by submerged breakwater structures to avoid the use of riprap. WETLAND REMEDIATIONAT FISH HATCHERY, TOPONAS, COLORADO Developed the wetland remediation design and construction drawings for the upper and lower meadow mitigation areas. Components of the remediation included creation of a three -cell system with water distribution achieved by multiple rock cascade outlets and spreader ditches for the upper meadow and a distribution ditch with intermittent timber drop structures with v-notch outlets for the lower meadow. Native seed and plantings restored wet meadow conditions in the upper meadow and installation of native woody species improved diversity in the lower meadow.

He has performed environmental and geologic investigations on hundreds of sites, has prepared written reports for most of these, and has delivered presentations on several dozen projects. Mr Baltzer manages the Western Colorado branch office of Walsh Environmental, ensuring that work produced in that office meets the high standards set by the corporate office. He also teaches various environmental courses for the Mesa State College Environmental Restoration Program. PROJECT EXPERIENCE ENVIRONMENTAL SITE ASSESSMENTS Mr. Baltzer has produced or assisted with over 1,000 ESAs on industrial, multi -family, retail, warehouse, vacant, and other properties. These ESAs, which follow the American Standards for Testing and Materials guideline, have revealed hidden contamination of various types. He performed level two site assessments and accurately quantified environmental contamination. He has prepared and implemented dozens of cleanup plans for contaminated sites. HAZARDOUS AND SPECIAL WASTE MANAGEMENT Mr. Baltzer arranges and ensures proper remediation, handling, and disposal of hazardous wastes. Waste removal projects have included wastes of unknown origin and content, and the treatment of hazardous wastes to render them non -hazardous. ASBESTOS PROJECTS Mr. Baltzer has performed hundreds of asbestos inspections of structures strictly following state and AHERA protocols. He has managed all types of asbestos -containing materials, focusing on identifying hazards, yet eliminating some suspect materials from abatement. Mr. Baltzer has worked with CDPHE to minimize abatement costs, and made recommendations for handling asbestos -containing materials resulting in substantial cost savings for his clients. He has prepared and implemented asbestos - contaminated soil removal projects. INDUSTRIAL HYGIENE AND HEALTH AND SAFETY Mr. Baltzer has performed numerous health and safety functions. In addition to preparing dozens of site - specific Health and Safety Plans, he has performed or managed health and safety projects. He has Jerry Barker Condition Class 1, 2, or 3, respectively. Community and structure hazards were determined using the NFPA 1144 procedure. Fire history and ignition rate potential defined wildfire risks. Proposed fuel projects included weed abatement within communities, strategically placed fuel breaks within 1-3 miles around communities, and managing FRCC 3 fuels to class FRCC 1. Non -fuel mitigation needs include strategically located water sources, public outreach, and improving the firefighting capabilities of the Rangeland Fire Protection Associations. Public meetings were convened to provide educational materials, present information on the need for the CWPP, discuss the findings of the analysis, and proposed hazardous fuels and non -fuel mitigation projects. PowerPoint presentations and wall maps were used to present wildfire risk and hazard findings and proposed mitigation projects. Dr. Barker participated in developing CWPPs for nine communities in the Kenai Peninsula Borough, Alaska. These projects required the identification of wildfire hazards and risk to communities, which were identified through fuels and structure surveys, and studying maps of fire regime condition class, fire history, and ignition risk potential. Hazardous fuel projects were prescribed based on community hazard and proximity of FRCC 3 fuels and ignitions risk potential. Non -fuel digitization priorities were defined through interviews with fire and county officials. PowerPoint presentation and maps were prepared for community meetings to discuss wildfire hazards, risks, and mitigation opportunities. WILDLAND —URBAN INTERFACE COMMUNITY -AT -RISK WILDFIRE RISK ASSESSMENT Dr. Barker was project manager and technical lead to teams conducting wildfire community -at -risk WUI projects to assess the risk of wildfire and develop mitigation plans to reduce its risk. Clients included Bureau of Land Management, Nevada Fire Safe Council, Tennessee Division of Forestry, Boise, Teton, and Power Counties, ID, and Eagle County, CO. This work required interacting with local, state and federal agencies to plan and coordinate project activities. Dr. Barker managed the fieldwork and community outreach efforts of teams conducting the wildfire hazard assessments. Fieldwork included fuel and structure inventories, community outreach and education, community profiling, and report preparation. Dr. Baker developed fire hazard assessments and mitigation plans for over 50 communities in Idaho, Oregon, Wyoming, Nevada, and Tennessee, and four counties in Idaho and Colorado. He participated in over 100 public meetings to educate communities on the risk of wildfire and actions that they could take to reduce its risk. Additionally, he worked with communities and fire management agencies to improve communication and coordination. For the BLM Oregon Vale District, Dr. Barker directed an effort to assess wildland fire risk for nine communities and define appropriate mitigation practices to reduce its risk in Malheur, Baker, and Wallowa Counties. Two field teams were simultaneously conducting the fuel and structures surveys to complete the field work within a 3-month period. The assessment areas around each community were approximately 150 square miles. Mitigation projects were defined based on field observation and interviews with agency staff, public officials, and private landowners. Two public meetings per community were convened to discuss fire risks and hazards, and potential mitigation projects. Detailed maps and reports that documented landscape and structure level of risk, potential mitigation projects, fire condition class, roads, surface water, and values at risk were produced. Dr. Barker has also served as range scientist and fire ecologist on the BLM's Roan Plateau Resource Management Plan Addendum and Environmental Impact Statement. For the BLM Upper and Lower Snake River Districts, Dr. Barker directed a large effort to assess wildland fire risk for 17 communities and define appropriate mitigation practices to reduce its risk. Four field teams were simultaneously conducting the fuels structure and community profile surveys to complete the field work within a 3-month period. Many assessment areas were over 100-miles square. Mitigation projects were defined based on field observation and interviews with agency staff, public officials, and private landowners. Two public meetings per community were convened to discuss fire risks and hazards, and potential mitigation projects. Detailed maps and reports that documented landscape and structure Jerry Barker Paae 3 level of risk, potential mitigation projects, fire condition class, roads, surface water, and values at risk were produced. WILDLAND FIRE MANAGEMENT PLANNING Dr. Barker is the technical lead for completing a wildland fire management plan for Buckley Air Force Base. The assessment required meetings with key staff, such as the Base Fire Marshall, Natural and Cultural Resources Manager, and Public Affairs Office. Some of the issues developed in the plan included existing conditions, firefighter training and equipment needs, wildland fire history, wildland fire effects, fuels, prescribed fire and smoke plume management, pre -fire planning and management, fire suppression actions, and post -fire actions. The plan meets the requirements of the newly promulgated Air Force wildland fire management regulations. NEPA ENVIRONMENTAL ASSESSMENTS Dr. Baker participated in an interdisciplinary team to complete an extensive and complex Environmental Assessment for Arizona BLM to revise current resource management plans and fire management plans to be compliant with the National Fire Management Plan (Arizona Statewide Land use Plan Amendment for Fire, Fuels, and Air Quality Management). He served as the resource lead for vegetation and fuels, range ecology and grazing, fire ecology and management, land use, and invasive weeds. He developed extensive descriptions of natural vegetation, wildland fuels, and invasive weeds. He also identified fire history, fire condition class, desired future condition, and appropriate fuels management practices for the vegetation classes. He described potential impacts of wildland fire on livestock grazing, land use, and invasive weed management. He coordinated the vegetation and fuels information with other resource leads. Dr. Barker is participating on the interdisciplinary team that is revising the Bureau of Land Management (BLM) Hollister Field Office 1984 Resource Management Plan (RMP). Dr. Barker is responsible for wildland fire management in this effort. Wildland fire management is a critical component of the revision because wildfire occurrence is frequent and prescribed fire is used to reduce hazardous fuels, improve wildlife habitat, and manage noxious and invasive weeds. The planning area was divided into eight fire management zones (FMZ) based on terrain, fuels, and management needs. Historic fire patterns, recent fire history, current management goals and practices were described for each FMZ. The EIS analysis considered four management alternatives with regard to wildland fire management, non -fire fuels management, livestock grazing and rangeland resources, special management areas, vegetation management, and post -fire rehabilitation and monitoring. Dr. Barker is also participating on an interdisciplinary team that is developing a Resource Management Plan and Environmental Impact Statement for BLM Colorado, Canyons of the Ancients Monument. Dr. Barker is responsible for wildland fuels and fire management, rangeland resources and grazing, vegetation, and noxious weeds in this effort. The planning area is divided into four vegetation types. Vegetation, noxious weeds, livestock grazing, fire history, fuels management, and rangeland use were described for each type. The associated EIS analysis will consider four management alternatives with regard to wildland fire management, non -fire fuels management, livestock grazing and rangeland resources, special management areas, vegetation management, and post -fire rehabilitation and monitoring. Dr. Barker participated on an interdisciplinary team to complete a comprehensive Environmental Assessment on forage allocation and grazing management for the BLM Jarbidge Field Office, Idaho (Permit Renewal and Vegetation Allocation Environmental Assessment). He served as the resource lead for vegetation, range ecology and grazing, wildland fire, and invasive weeds evaluations. He identified and described current vegetation types on 19 grazing allotments. He reviewed allotment management plans to make recommendations to BLM on the method used to calculate livestock animal unit months and forage allocation. He also evaluated and compared forage allocation and grazing management based on current practices and compared them with two other management options, including the desired future condition. After identifying noxious and invasive weeds, he projected population impacts of various Jerry Barker management options. Additionally, he evaluated fire history and potential future impacts on grazing management options. Dr. Barker also recently completed an EA for expansion of the Colowyo coal mine in Meeker, Colorado. ECOLOGICAL INDICATOR DEVELOPMENT FOR RESOURCE CHARACTERIZATION AND MONITORING Dr. Barker led an interdisciplinary team that evaluated approximately 100 riparian forest stands in western Oregon to develop indicators for resource characterization, vegetation structure and function, and woody debris loading for long-term monitoring. He provided project specifications on the implementation and evaluation of survey methods and protocols, data acquisition, and statistical data analysis. He developed and evaluated indicator metrics and indices of ecological condition of riparian forests using conceptual models, new and existing data, and computerized statistical analytical programs. He then convened a workshop of regional riparian scientists to discuss the successes and problems of several acceptable protocols for monitoring riparian forests, identified common metrics among the different approaches, and proposed a new monitoring approach that could be widely used. Dr. Barker was team lead of an effort that characterized the historical vegetation of watersheds and riparian corridors in eastern Oregon. He used General Land Office survey records, journals, pictures, potential natural vegetation maps, and bird habitat characteristics to describe forest, grassland, and riparian vegetation structure and composition ca. 1885. This information was used to describe pristine attributes for categorizing current watershed and riparian conditions. Dr. Barker developed a method to judge ecological site condition and indicators of grazing intensity for the central coast rangelands of Somalia, East Africa. Gradients of grazing intensity were used to identify vegetation structure and composition, and soil surface indicators of low-, moderate-, and high -intensity livestock grazing. Ecological site condition classes were described based on vegetation and soil conditions of high -use and low -use areas. The ecological site indicators and classes were then tested for applicability throughout the region and ease of use by Somali range managers. Dr. Barker developed ecological indicators of visitor impact on scenic view areas and campgrounds at Bryce Canyon National Park, Utah. Low- and high -use areas were identified based on park ranger perception of use for a given scenic view area or campground. Vegetation and soil -surface attributes were evaluated to characterize difference among low -use, high -use, and no -use areas. Vegetation attributes consisted of plant cover, density, frequency, and observable tissue damage. The soil attributes measured were soil bulk density, soil infiltration rate, overland water flow, and sediment production. Subsequently, ecological indicators were defined that could be used to assess the degree of impact from visitor use. AIR POLLUTION EFFECTS ON ECOSYSTEMS He led a team that assessed the potential effects of alternative motor fuel combustion products on vegetation. Literature reviews were used to identify combustion products from fuel additives, such as methanol and MTBE, at various mixtures with gasoline and 100% methanol. Formaldehyde was found to be a common pollutant at high concentrations in most fuel mixtures. Four plant species were exposed to various concentrations of formaldehyde -contaminated fog in greenhouses over a several week period. Analytical models were employed to evaluate potential vegetation exposure in the South Coast Air Basin of California given various assumptions of methanol and MTBE fuel use by vehicles. Dr. Barker convened a workshop of internationally renowned biodiversity and air pollution scientists to assess the potential effects of air pollution on biodiversity and solicited the Electrical Power Research Institute and US Fish and Wildlife Service to co-sponsor the workshop. He chaired the interdisciplinary workshop and served as lead editor for the subsequent book based on the proceedings. Walsh Emironmcntal Scientists and Engineers.
