Box 580 Fort Collins, Colorado 80522-0580 Subject: Revised Proposal — Limited Phase II Environmental Site Assessment Lovell and Stark Properties 1911 and 1915 East Mulberry Street, Fort Collins, Colorado WALSH Proposal Number: WA-002011-0001-OOTTO Dear Lois: At your request, Walsh Environmental Scientists and Engineers, LLC (WALSH) has prepared this revised proposal and cost estimate to conduct Limited Phase II Environmental Site Assessment (ESA) activities at the Lovell and Stark Properties consisting of parcel numbers 87181-06-001, 87181-06-002, and 87181-00-090 located at 1911 and 1915 East Mulberry Street in Fort Collins, Colorado (Site). The proposed assessment activities are targeted in nature and based on findings included in a Phase I ESA report for the Site prepared by WALSH dated February 22, 2013 and a draft Phase I ESA report for the Stark Property prepared by Tetra Tech, Inc. dated, December 19, 2012. In addition, the proposed assessment activities are also based on proposed Site reuse/redevelopment plans indicated during a meeting with City of Fort Collins representatives on January 23, 2013, on visual observation made during an inspection of the Site on January 25, 2013, and on subsequent telephone conversations/email correspondence with City representatives. Historically, the Site has reportedly been used for a variety of activities including, sugar beet lime waste disposal, semi -tractor trailer rental for storage purposes, landscape material storage, river gravel/soil stockpile disposal, and unsupervised dumping of household and solid waste (including demolition debris). Several recognized environmental conditions (RECs) or potential RECs were identified in the draft Phase I ESA report prepared by Tetra Tech, Inc. including, numerous petroleum -stained soils and point sources from releases from fuel tanks on the storage trailers, containers of waste oil and other undefined liquids with evidence of leakage/spillage, and disposal of sugar beet lime wastes. In addition, a previous investigation by other researchers (National Inspection Services) on the Lovell Property indicated the presence of low concentrations of volatile organic/petroleum compounds in groundwater which were suspected to originate from an off -site source. Additional RECs identified in the WALSH Phase I ESA report included the presence of used oil in open containers and drums, stained or Fort Collins Office: 2629 Redwing Road • Suite 280 • Fort Collins.

The objectives of this project are to establish current environmental conditions related to potential on -site and off -site contaminants and assess those potential contaminants that may affect proposed reuse/redevelopment activities. The key proposed assessment activities include: • Advancing up to 12 shallow soil borings to evaluate which chemicals of concern are present or absent on the Site. The shallow soil borings shall be advanced to a maximum depth of 10 feet. Collecting representative shallow and subsurface soil samples from the borings. o Six borings advanced in the vicinity of observed stained soil areas (borings SS-01 through SS-06). o Up to two additional opportunity borings advanced in the vicinity of potential stained soil areas (borings SS-07 through SS-08). o One boring advanced in the vicinity of petroleum above -ground storage tanks and waste oil storage containers (boring TCS-01). o One boring advanced in the vicinity of 55-gallon waste oil storage drums (boring DS-01). o One boring advanced in the vicinity of suspected damaged electronic devices (boring ED-01). o One boring advanced in the vicinity of spilled unknown liquid (boring UL-01). • Advancing 11 deep soil borings and installing 11 temporary monitoring wells to evaluate which chemical constituents are present or absent on the Site. Our proposal assumes a depth to water of 12 feet. Collecting representative subsurface soil and grab groundwater samples from each boring/well. o Four borings/wells installed in upgradient locations to evaluate impacts from potential off -site sources (borings UG-01 through UG-04). o Two borings/wells installed in vicinity of stained soil source areas (borings SA-01 and SA-02). o One boring/well installed in the vicinity of petroleum above -ground storage tanks and waste oil storage containers (boring TCA-01). o One boring/well installed in the vicinity of 55-gallon waste oil storage drums (boring DA-01). o One boring/well installed in vicinity of a concrete vault (boring CV-01). o Two borings/wells installed in down -gradient locations (borings DG-01 and DG-02).

Scope of Work Health and Safety, Utility Locate, and Notification A site -specific health and safety plan will be prepared prior to the initiation of field activities. In addition, a public utility locate will be completed to assess the locations of known utilities/subsurface structures. Prior to commencing drilling, WALSH will prepare required Notice of Intent to Construct Monitor/Test Holes forms and submit to the Colorado Division of Water Resources for approval. Sampling Locations A figure depicting the proposed soil boring/temporary well locations for select sampling stations is attached. Locations of opportunity stained soil and asbestos -containing debris samples are not indicated on the attached figure and will be determined in the field. Proposed boring locations have been pre -selected but the final location will be determined in the field based upon location of overhead or buried utilities and other restrictive Site conditions. Drilling and Soil Sampling The proposed drilling firm is DrillPro Services, Inc. located in Thornton, Colorado. Soil borings will be advanced using a Hurricane truck mounted hydraulic (direct) push system. Continuous core samples will be collected from the existing ground surface to the desired drill depth, using 3.25-inch outside diameter, 4-foot long core barrels. Recovered soil intervals will be classified by WALSH field geologist according to the Unified Soil Classification System. All soil intervals will be screened for the presence of volatile organic compounds (VOCs) using a hand held photo -ionization detector (PID). Representative shallow and subsurface soil samples will be collected from visibly stained intervals and/or the interval which displays the highest elevated reading on the PID. If staining or detectable volatile organic concentrations are not present in a particular boring, the soil sample will be collected from an interval above the presumed water table interface. Samples from these borings will likely be obtained from a variety of depths depending on the conditions encountered in the field. Fort Collins Office: 2629 Redwing Road • Suite 280 • Fort Collins.

LLC an ecology and environment company Groundwater Well Installation and Sampling Temporary wells will be installed to evaluate chemical constituents present in the shallow alluvial aquifer. It is estimated that groundwater beneath the Site is present at a depth of approximately 12 feet below existing ground surface. All borings installed for shallow alluvial aquifer evaluation purposes will be advanced to an anticipated maximum depth of 17 feet below existing ground surface. The temporary wells will be constructed of one -inch outside diameter threaded Schedule 40 poly -vinyl chloride (PVC) pipe. A 10-foot screened interval (factory -slotted to 0.010 inch) will be installed at the base of each boring, blank riser pipe will then be extended to approximately six inches above the ground surface. Threaded bottom caps will be used on the each temporary well. Because it is anticipated that alluvial sands and gravels will be encountered at depth, native material will be allowed to backfill the annulus and the remaining bore hole will remain as an "open hole" completion during the sampling process. Grab groundwater samples will be collected from the temporary wells using a Wattera inertial pump sampling method and dedicated tubing. An alternative groundwater sampling method will be to utilize dedicated disposable bailers. Opportunity Samples (Asbestos) Several suspect asbestos -containing materials were identified on the ground surface, as well as on and in soil piles during the visual inspection of the Site. Additional suspect asbestos -containing debris could be encountered during the drilling process. Representative samples of observed suspect asbestos -containing debris will be collected for laboratory analysis. Decontamination Dedicated sampling equipment will be utilized to the maximum extent practicable. Non - dedicated equipment (i.e., groundwater meters, sampling spoons, cutting shoes, soil sampling tubes, etc.) will be decontaminated before initial use and between boreholes using a tap water and detergent wash and then a final tap water rinse. If visible amounts of petroleum or similar compounds are observed on the drilling equipment, a hot water/steam wash can be incorporated into the decontamination protocol. Costs for hot water/steam decontamination, collection, and disposal of wash water have not been incorporated into this proposal. Well Surveying Relative elevation data for the top of well casing and groundwater level will be obtained at each temporary well. A total survey station will be used to collect survey information for the subsequent preparation of a potentiometric surface (groundwater elevation) map. The temporary wells will be decommissioned following completion of well surveying activities. Fort Collins Office: 2629 Redwing Road • Suite 280 • Fort Collins.

LLC an ecology and environment company Investigation Derived Wastes It is anticipated that no significant investigation derived waste will be generated during the field investigation and will likely consist of personal protective equipment and temporary well materials. These materials will be disposed off -site as general refuse. Soil borings will be backfilled with residual cuttings or with hydrated bentonite chips if cuttings were not available, to within one foot of existing ground surface. The remaining portion of the borehole will be filled with hydrated bentonite chips. Decontamination water will be thin spread on visibly stained areas. Laboratory Analyses The chemicals of concern identified for this investigation include volatile organic compounds (VOCs), semi -volatile organic compounds (SVOCs), petroleum hydrocarbons [namely benzene, toluene, ethylbenzene, and xylenes (BTEX), gasoline range organics (GRO), diesel range organics (DRO), oil and grease (O&G), and methyl tertiary butyl ether (MTBE], 8 Resource Conservation and Recovery Act (RCRA) metals, and asbestos.

Quality assurance/quality control (QA/QC) volatile organic trip blank samples will be included with the soil and groundwater shipment. All asbestos -containing debris samples will be placed in dedicated plastic bags. Nitrile gloves will be used during the collection of all samples. A new set of gloves will be used for each set of samples collected. Appropriate chain of custody documentation will be completed and accompany the samples to the laboratory. The proposed analytical facilities are eAnalytics Laboratory located in Loveland, Colorado and Reservoirs Environmental, Inc. located in Denver, Colorado.

The report will explain the investigation, sampling procedures and protocols, and present the laboratory results of the soil, groundwater, and other sample analyses. Analytical results will be presented in tabular format and compared to applicable State and Federal regulations/guidelines for the chemicals of concern. The report will also provide a conclusions and recommendations section. The report will also contain appendices which include detailed descriptions of the soil profile at each soil borings location, figures indicating the sample locations and observed groundwater flow direction, as well as the complete laboratory analytical records and chain of custody forms. Schedule and Costs WALSH can initiate the proposed assessment activities at the City's convenience. A tentative schedule is presented below. • Scheduling, Subcontracting, Well Construction Notification, Underground Utility Location, and Health and Safety Plan Development, Laboratory Coordination (1 to 2 Weeks) • Drilling, Soil Boring/Sampling, and Well Installation/Groundwater Sampling, and Surveying (2.5 Days) • Laboratory Analysis of Samples (standard turnaround time) (1 to 1.5 Weeks) • Data Review and Analysis, and Report Preparation (2 Weeks) The estimated costs to complete the services described above is approximately $29,156. A summary of the labor, subcontractor, and other direct costs (ODCs) are detailed on an attached spreadsheet. The estimated costs include a 10% contingency on labor, subcontractor, and ODCs. WALSH proposes to complete the project on a time and materials basis. Assumptions/Limitations This proposal assumes that the assessment activities will be performed when there is no wet surficial soil or snow cover present at the Site. It assumes that the required borings will be completed over a two day period using a direct push device. The proposed drilling and well depths will likely vary but it is assumed that the total drilling depth by direct push technology is 267 feet. Total temporary groundwater well materials installed are estimated to be 187 feet. In the event that unforeseen conditions are encountered (such as difficult drilling conditions, buried objects, or other obstructions) additional costs may be incurred including additional labor hours or the need to employ a different drilling or sampling method. A standard one week analytical turn -around time has been budgeted for the majority of laboratory sample analysis. Costs have been included for the supplemental analysis of up to three asbestos -containing debris samples on an expedited 24- Fort Collins Office: 2629 Redwing Road • Suite 280 • Fort Collins.

The objectives of this project are to establish current environmental conditions related to potential on -site and off -site contaminants and assess those potential contaminants that may affect proposed reuse/redevelopment activities. The key proposed assessment activities include: • Advancing up to 12 shallow soil borings to evaluate which chemicals of concern are present or absent on the Site. The shallow soil borings shall be advanced to a maximum depth of 10 feet. Collecting representative shallow and subsurface soil samples from the borings. o Six borings advanced in the vicinity of observed stained soil areas (borings SS-01 through SS-06). o Up to two additional opportunity borings advanced in the vicinity of potential stained soil areas (borings SS-07 through SS-08). o One boring advanced in the vicinity of petroleum above -ground storage tanks and waste oil storage containers (boring TCS-01). o One boring advanced in the vicinity of 55-gallon waste oil storage drums (boring DS-01). o One boring advanced in the vicinity of suspected damaged electronic devices (boring ED-01). o One boring advanced in the vicinity of spilled unknown liquid (boring UL-01). • Advancing 11 deep soil borings and installing 11 temporary monitoring wells to evaluate which chemical constituents are present or absent on the Site. Our proposal assumes a depth to water of 12 feet. Collecting representative subsurface soil and grab groundwater samples from each boring/well. o Four borings/wells installed in upgradient locations to evaluate impacts from potential off -site sources (borings UG-01 through UG-04). o Two borings/wells installed in vicinity of stained soil source areas (borings SA-01 and SA-02). o One boring/well installed in the vicinity of petroleum above -ground storage tanks and waste oil storage containers (boring TCA-01). o One boring/well installed in the vicinity of 55-gallon waste oil storage drums (boring DA-01). o One boring/well installed in vicinity of a concrete vault (boring CV-01). o Two borings/wells installed in down -gradient locations (borings DG-01 and DG-02).

Scope of Work Health and Safety, Utility Locate, and Notification A site -specific health and safety plan will be prepared prior to the initiation of field activities. In addition, a public utility locate will be completed to assess the locations of known utilities/subsurface structures. Prior to commencing drilling, WALSH will prepare required Notice of Intent to Construct Monitor/Test Holes forms and submit to the Colorado Division of Water Resources for approval. Sampling Locations A figure depicting the proposed soil boring/temporary well locations for select sampling stations is attached. Locations of opportunity stained soil and asbestos -containing debris samples are not indicated on the attached figure and will be determined in the field. Proposed boring locations have been pre -selected but the final location will be determined in the field based upon location of overhead or buried utilities and other restrictive Site conditions. Drilling and Soil Sampling The proposed drilling firm is DrillPro Services, Inc. located in Thornton, Colorado. Soil borings will be advanced using a Hurricane® truck mounted hydraulic (direct) push system. Continuous core samples will be collected from the existing ground surface to the desired drill depth, using 3.25-inch outside diameter, 4-foot long core barrels. Recovered soil intervals will be classified by WALSH field geologist according to the Unified Soil Classification System. All soil intervals will be screened for the presence of volatile organic compounds (VOCs) using a hand held photo -ionization detector (PID). Representative shallow and subsurface soil samples will be collected from visibly stained intervals and/or the interval which displays the highest elevated reading on the PID. If staining or detectable volatile organic concentrations are not present in a particular boring, the soil sample will be collected from an interval above the presumed water table interface. Samples from these borings will likely be obtained from a variety of depths depending on the conditions encountered in the field.

It is estimated that groundwater beneath the Site is present at a depth of approximately 12 feet below existing ground surface. All borings installed for shallow alluvial aquifer evaluation purposes will be advanced to an anticipated maximum depth of 17 feet below existing ground surface. The temporary wells will be constructed of one -inch outside diameter threaded Schedule 40 poly -vinyl chloride (PVC) pipe. A 10-foot screened interval (factory -slotted to 0.010 inch) will be installed at the base of each boring, blank riser pipe will then be extended to approximately six inches above the ground surface. Threaded bottom caps will be used on the each temporary well. Because it is anticipated that alluvial sands and gravels will be encountered at depth, native material will be allowed to backfill the annulus and the remaining bore hole will remain as an "open hole" completion during the sampling process. Grab groundwater samples will be collected from the temporary wells using a Wattera inertial pump sampling method and dedicated tubing. An alternative groundwater sampling method will be to utilize dedicated disposable bailers. Opportunity Samples (Asbestos) Several suspect asbestos -containing materials were identified on the ground surface, as well as on and in soil piles during the visual inspection of the Site. Additional suspect asbestos -containing debris could be encountered during the drilling process. Representative samples of observed suspect asbestos -containing debris will be collected for laboratory analysis. Decontamination Dedicated sampling equipment will be utilized to the maximum extent practicable. Non - dedicated equipment (i.e., groundwater meters, sampling spoons, cutting shoes, soil sampling tubes, etc.) will be decontaminated before initial use and between boreholes using a tap water and detergent wash and then a final tap water rinse. If visible amounts of petroleum or similar compounds are observed on the drilling equipment, a hot water/steam wash can be incorporated into the decontamination protocol. Costs for hot water/steam decontamination, collection, and disposal of wash water have not been incorporated into this proposal. Well Surveying Relative elevation data for the top of well casing and groundwater level will be obtained at each temporary well. A total survey station will be used to collect survey information for the subsequent preparation of a potentiometric surface (groundwater elevation) map. The temporary wells will be decommissioned following completion of well surveying activities. 'Port Collins Office:-G1til Redwing Road • Suitc 280 •Parr Collins.

These materials will be disposed off -site as general refuse. Soil borings will be backfilled with residual cuttings or with hydrated bentonite chips if cuttings were not available, to within one foot of existing ground surface. The remaining portion of the borehole will be filled with hydrated bentonite chips. Decontamination water will be thin spread on visibly stained areas. Laboratory Analyses The chemicals of concern identified for this investigation include volatile organic compounds (VOCs), semi -volatile organic compounds (SVOCs), petroleum hydrocarbons [namely benzene, toluene, ethylbenzene, and xylenes (BTEX), gasoline range organics (GRO), diesel range organics (DRO), oil and grease (O&G), and methyl tertiary butyl ether (MTBE], 8 Resource Conservation and Recovery Act (RCRA) metals, and asbestos.

Analytical results will be presented in tabular format and compared to applicable State and Federal regulations/guidelines for the chemicals of concern. The report will also provide a conclusions and recommendations section. The report will also contain appendices which include detailed descriptions of the soil profile at each soil borings location, figures indicating the sample locations and observed groundwater flow direction, as well as the complete laboratory analytical records and chain of custody forms. Schedule and Costs WALSH can initiate the proposed assessment activities at the City's convenience. A tentative schedule is presented below. • Scheduling, Subcontracting, Well Construction Notification, Underground Utility Location, and Health and Safety Plan Development, Laboratory Coordination (1 to 2 Weeks) • Drilling, Soil Boring/Sampling, and Well Installation/Groundwater Sampling, and Surveying (2.5 Days) • Laboratory Analysis of Samples (standard turnaround time) (1 to 1.5 Weeks) • Data Review and Analysis, and Report Preparation (2 Weeks) The estimated costs to complete the services described above is approximately $29,156. A summary of the labor, subcontractor, and other direct costs (ODCs) are detailed on an attached spreadsheet. The estimated costs include a 10% contingency on labor, subcontractor, and ODCs. WALSH proposes to complete the project on a time and materials basis. Assumptions/Limitations This proposal assumes that the assessment activities will be performed when there is no wet surficial soil or snow cover present at the Site. It assumes that the required borings will be completed over a two day period using a direct push device. The proposed drilling and well depths will likely vary but it is assumed that the total drilling depth by direct push technology is 267 feet. Total temporary groundwater well materials installed are estimated to be 187 feet. In the event that unforeseen conditions are encountered (such as difficult drilling conditions, buried objects, or other obstructions) additional costs may be incurred including additional labor hours or the need to employ a different drilling or sampling method. A standard one week analytical turn -around time has been budgeted for the majority of laboratory sample analysis. Costs have been included for the supplemental analysis of up to three asbestos -containing debris samples on an expedited 24- Fort Collins Office: '_629 Redwing Rnad • Suite 280 • Von Collins.
