Senior Project Manager Principal Exhibit A Scope of Work Supplemental Environmental and Engineering Services Elgin Salvage Redevelopment Sites 464 McBride Street City of Elgin Terracon Proposal No. P050085 A. PROJECT INFORMATION The Elgin Salvage Redevelopment Sites comprise two properties located at 464 McBride Street (Main Yard) and 20 Jefferson Avenue (Jefferson Yard) in Elgin, Illinois. Under a contract with the City of Elgin dated October 8, 2003 and amended May 26, 2004, Terracon has completed the initial environmental tasks associated with preparing the two sites for redevelopment. Task completed to date include: • Review of existing docurnents • Preparation of Phase I Environmental Site Assessment Reports • Conducting an Asbestos Survey • Conducting subsurface site investigation and completion of comprehensive Site Investigation Reports for both parcels. • Enrollment of the sites into the Illinois Site Remediation Program. The Illinois EPA Site Remediation Program (SRP) has recently reviewed the comprehensive Site Investigation Reports and issued comments on each site. This Scope of Work addresses additional site investigation needs at the McBride Street site. A separate work authorization is anticipated to be submitted to address continued needs related to the Jefferson Avenue parcel. McBride Street Site Status The McBride Street site was the location of the major salvage yard operations including equipment dismantling, material segregation, crushing and baling of ferrous metals, scrap metal storage and related activities. The site investigation was conducted to assess a wide range of potential contaminants based on the varied operations and the large number of potential contaminants that are associated with salvage yard operations. The results of the Site Investigation indicated substantial contamination of soil and groundwater above TACO (Tiered Approach to Corrective Action Objectives) Tier 1 residential clean up objectives. The IEPA has requested additional site investigation work to delineate specific areas of the site and provide supplemental data. To address IEPA's comments, additional soil borings, surface sampling, physical assessment, and groundwater monitoring wells will be necessary. 1 Exhibit A - Scope of Work Elgin Salvage Redevelopment Sites - McBride Street Site lrerraeon Elgin, IL Terracon Proposal No. P050085 Another significant project issue is the potential presence of dioxins/furans in soil and groundwater. Dioxin/furans are contaminants associated with the operation of an on-site wire-burning incinerator from 1981 to 1987. The presence of these contaminants is attributable to incomplete combustion within the incinerator. Because clean up standards for dioxin/furans are not currently contained in the TACO regulations, Terracon prepared the project work plan and conducted the investigation based on the premise that IEPA would accept a 1.0 part per billion (ppb) soil remediation objective for dioxin/furans. The use of the 1.0 ppb objective was based on several precedents established at other sites under the jurisdiction of both IEPA and USEPA. However, over the last few years, USEPA has conducted extensive research and reevaluation of the health risks associated with dioxin/furans. These studies, although not finalized or promulgated into formal regulations, have resulted in IEPA requiring substantially more conservative site clean up objectives at this time. Thus, as of January 20, 2005, the IEPA has issued site-specific standards for the McBride Street site as low as 0.0043 ppb (equivalent to 4.3 parts per trillion) 'for the residential soil ingestion standard. With these significantly more stringent standards, additional site evaluation will be necessary to determine those areas that are impacted by residual dioxin/furans and where remediation may be necessary. Terracon understands that environmental work related to the McBride Street site is presently funded through a state grant. To meet the time constraints posed by the grant, it is necessary to proceed as quickly as possible with the initial phases of site clean up. To meet the schedule, Terracon is recommending a phased process that will initiate clean up work in April 2005. The first phase of work will include asbestos abatement, building demolition, underground storage tank (UST) removal, and removal of grossly contaminated soil as identified by the site investigation work completed to-date. Once the final site investigation work is completed, and following the initial remediation, a second phase of remedial work can be anticipated. During this separate remediation effort, the site will be addressed based on the final remediation objectives. B. SCOPE OF SERVICES The tasks proposed under this scope of work relate to the McBride Street site and include: Task 1000 Additional Site Investigation Task 1100 Building Demolition and Initial Remediation Specifications Each of the recommended tasks is described below. 2 Exhibit A - Scope of Work Elgin Salvage Redevelopment Sites -McBride Street Site Herraeon Elgin, IL Terracon Proposal No. P050085 Task 1000—Additional Site Investigation Terracon has recommended to the City additional site investigation activities to address the specific questions posed by the IEPA's review letter dated January 12, 2005. The additional site investigation will aid in defining specific areas of the site that will require remediation and provide data to further refine the proposed remedial plans and associated costs. Elements of the additional site investigation are described below. Work Plan Upon receipt of the City's authorization, a work plan will be developed to perform the supplemental investigation of the Salvage Yard sites. The work plan will be developed in accordance with Illinois SRP requirements and will identify sampling procedures, laboratory analytical methods, and quality control methods for the work. In developing the work plan, Terracon will build upon the information obtained during the initial site investigation studies to determine the appropriate locations of proposed soil and groundwater sampling locations. Terracon will consult with the IEPA Project Manager to reach a common understanding of the site investigation plan. The focus of the work will be to delineate contamination source areas, assess the presence of dioxinifurans, and evaluate areas that may exceed the soil attenuation capacity. Soil and Groundwater Assessment In conducting the additional investigation, Terracon will utilize generally accepted environmental sampling procedures to assess and delineate current site conditions by means of advancement of soil borings and installation of groundwater monitoring wells. For the soil investigation, GeoProbe sampling will be conducted as a means of maximizing the production rate of field sampling activity. Based on the IEPA comments, Terracon proposes to advance 30 soil borings at the McBride Street site. The analytical schedule is similar to the initial site investigation, but will be tailored to the specific contamination source areas identified during the original investigation program. This will help to reduce the overall analytical costs. The primary analytical parameters will include semi- volatile organic compounds (SVOCs), priority pollutant metals (13), and PCBs. To address concerns related to soil attenuation limits, field assessment using Petroflag test kits and analytical testing for total petroleum hydrocarbons (TPH) will be performed. In addition, sampling for dioxins/furans will be performed using both the RapidScreen analytical procedure and the complete USEPA Method 8290 analytical procedures. Table 3, attached, provides a list of all proposed analytical work for the investigation. 3 Exhibit A— Scope of Work Elgin Salvage Redevelopment Sites—McBride Street Site l�erraeon Elgin. IL Terracon Proposal No. P050085 Five additional monitoring wells will be installed on the I•AcBride parcel to delineate groundwater contamination across the site. Two of these wells are necessary to replace wells that have been damaged over time. One round of samples is included in the proposed scope of services to sample and analyze each of the new wells. Four tree product gauging wells will also be installed in the area of concern located in the northwest portion of the McBride Site where free product was encountered. These wells will be utilized to further- delineate the area where free product is present. These wells will be gauged for the presence of free product; analytical sampling is not anticipated at this time. Standard site characterization methods and field procedures will include: • Notification of JULIE, the utility locating service, to identify utilities at the site prior to initiating drilling activities. Terracon will also consult with other knowledgeable parties, who may have information regarding private on-site utilities, if available. • Soil screening protocols will include use of a photoionization detector (PID) combined with olfactory and visual screening to select subsurface soil samples. • Soil cuttings generated during GeoProbe sampling will be returned to the boreholes to minimize waste disposal costs. For monitoring well installation, soils and purge water will be containerized and disposed of on a unit cost basis. • Analytical methods will be in accordance with SW-846 methods: all analytical work will be performed by an accredited laboratory. • Terracon expects to utilize Level D personal protective equipment when conducting field investigation work. Task 1100 — Building Demolition and Initial Remediation Specifications To solicit contractor bids for the demolition of the on-site structures and implement the initial remediation elements, a complete bid specification package will be prepared. This bid specification will address the following efforts: Asbestos Abatement' • Building Demolition (Including Concrete Foundations and Special Structures) • Underground Storage Tank Removal • Removal and Disposal of Drurnmed Materials and Miscellaneous Debris • Environmental Remediation (Areas of Gross Contamination) • Site Controls and Utilities • Site Grading and Removal of Visually Impacted Surface Soils Costs associated with abatement specifications were budgeted under Amendment No. 1 of the contract and are not duplicated herein. 4 Exhibit A- Scope of Work Elgin Salvage Redevelopment Sites -McBride Street Site lrerracon Elgin, IL Terracon Proposal No. P050085 The bid specification will be prepared to include the City of Elgin's standard general conditions and agreement forms to address contracting issues such as bonding, insurance, EEO participation and union wage scales. As part of this task, Terracon will update the project cost estimate based on the final specifications, provide coordination with City staff to publicly bid the work, attend one pre-bid meeting with prospective contractors (site walk through); and review and tabulate the bids received. Future work associated with the site will include environmental field oversight during the demolition work. During the demolition process, Terracon anticipates the need to conduct sampling and assessment of various subsurface features such as pits, floor drains, pipe chases and similar items that cannot cost-effectively be investigated prior to building demolition. Following the remediation, the City should expect that the IEPA will require confirmation sampling to ensure that the remediation objectives are met. Effort and costs to conduct this work is not included in this scope of work. C. SCHEDULE Bid specifications will be prepared for release to Contractors by February 18, 2005. Additional site investigation will be conducted from February 15 to April 15, 2005. D.

Proposal No. P050085 1 City of Elgin Agenda Item No. riit", February 4, 2005 TO: Mayor and Members of the City Council ALIVE DOWNTOWN FROM: Olufemi Folarin, Acting City Manager Raymond H. Moller, Director of Econo is Development And Business Services SUBJECT: Amendment #2 to Environmental Testing Services Contract with Terracon Inc. at 464 McBride Street. PURPOSE The purpose of this memorandum is to provide the Mayor and members of the City Council with information to consider a second amendment for environmental testing services with Terracon Inc. at 464 McBride Street. RECOMMENDATION It is recommended that the City Council authorize a second amendment to the current contract with Terracon Inc. for environmental testing services at 464 McBride Street for an amount not to exceed $69,587.00. BACKGROUND The Riverfront/Center City Master Plan calls for the redevelopment of the area north of Ann Street and west of North Grove Avenue for an upscale residential land use. This area consists of three parcels of property: the former City of Elgin Public Works yard, Elgin Salvage, and the former Seigle's McBride Street warehouse site. All three sites are owned by the City of Elgin. The land area totals approximately 20 acres. In 2002, the City accepted a grant for $4.85 million from the State of Illinois Department of Commerce and Economic Opportunity for the purchase, remediation, and redevelopment of the Elgin Salvage site. In preparation for conducting the initial environmental testing at the Elgin Salvage site, the City issued a Request for Qualifications for Environmental Consulting Services on June 20, 2003. RFQ's were sent to eight environmental consulting firms. Qualification statements were received from six firms on July 14, 2003. A staff committee found Terracon Inc. to be the most qualified Amendment to Environmental Testing Services Contract w/Terracon February 4, 2005 Page 2 The Elgin Salvage redevelopment site is comprised of two properties located at 464 McBride Street (Main Yard) and 20 Jefferson Avenue (Jefferson Yard) in Elgin, Illinois. Under a contract with the City of Elgin dated October 8, 2003, ($96,132) and a second amendment dated May 26, 2004, Terracon has completed the initial environmental tasks associated with preparing the two sites for redevelopment. Task completed to date include: • Review of existing documents • Preparation of Phase I Environmental Site Assessment Reports • Conducting an Asbestos Survey • Conducting subsurface site investigation and completion of comprehensive Site Investigation Reports for both parcels. • Enrollment of the sites into the Illinois Site Remediation Program. The Illinois Environmental Protection Agency (IEPA) Site Remediation Program (SRP) has recently reviewed the comprehensive Site Investigation Reports and issued comments on each site. This Scope of Work addresses additional site investigation needs at the McBride Street site as required by the IEPA. A separate work authorization is anticipated to be submitted to address continued needs related to the Jefferson Avenue parcel. McBride Street Site Status The McBride Street site was the location of the major salvage yard operations including equipment dismantling, material segregation, crushing and baling of ferrous metals, scrap metal storage and related activities. The site investigation was conducted to assess a wide range of potential contaminants based on the varied operations and the large number of potential contaminants that are associated with salvage yard operations. The results of the Site Investigation indicated substantial contamination of soil and groundwater above TACO (Tiered Approach to Corrective Action Objectives) Tier 1 residential clean up objectives. The IEPA has requested additional site investigation work to delineate specific areas of the site and provide supplemental data. To address IEPA's comments, additional soil borings, surface sampling, physical assessment, and groundwater monitoring wells will be necessary. Another significant project issue is the potential presence of dioxins/furans in soil and groundwater. Dioxin/furans are contaminants associated with the operation of an on-site wire- burning incinerator from 1981 to 1987.

SCOPE OF SERVICES The tasks proposed under this scope of work relate to the McBride Street site and include: • Task 1000 Additional Site Investigation • Task 1100 Building Demolition and Initial Remediation Specifications Each of the recommended tasks is described below. Task 1000—Additional Site Investigation Terracon has recommended to the City additional site investigation activities to address the specific questions posed by the IEPA's review letter dated January 12, 2005. The additional site investigation will aid in defining specific areas of the site that will require remediation and provide data to further refine the proposed remedial plans and associated costs. Elements of the additional site investigation are described below. Amendment to Environmental Testing Services Contract w/Terracon February 4, 2005 Page 4 Work Plan Upon receipt of the City's authorization, a work plan will be developed to perform the supplemental investigation of the Salvage Yard sites. The work plan will be developed in accordance with Illinois SRP requirements and will identify sampling procedures, laboratory analytical methods, and quality control methods for the work. In developing the work plan, Terracon will build upon the information obtained during the initial site investigation studies to determine the appropriate locations of proposed soil and groundwater sampling locations. Terracon will consult with the IEPA Project Manager to reach a common understanding of the site investigation plan. The focus of the work will be to delineate contamination source areas, assess the presence of dioxin/furans, and evaluate areas that may exceed the soil attenuation capacity. Soil and Groundwater Assessment In conducting the additional investigation, Terracon will utilize generally accepted environmental sampling procedures to assess and delineate current site conditions by means of advancement of soil borings and installation of groundwater monitoring wells. Based on the IEPA comments, Terracon proposes to advance 30 soil borings at the McBride Street site. The analytical schedule is similar to the initial site investigation, but will be tailored to the specific contamination source areas identified during the original investigation program. This will help to reduce the overall analytical costs. The primary analytical parameters will include semi-volatile organic compounds (SVOCs), priority pollutant metals (13), and PCBs. To address concerns related to soil attenuation limits, field assessment using Petroflag test kits and analytical testing for total petroleum hydrocarbons (TPH) will be performed. In addition, sampling for dioxins/furans will be performed using both the RapidScreen analytical procedure and the complete USEPA Method 8290 analytical procedures. Five additional monitoring wells will be installed on the McBride parcel to delineate groundwater contamination across the site. Two of these wells are necessary to replace wells that have been damaged over time. One round of samples is included in the proposed scope of services to sample and analyze each of the new wells. Four free product gauging wells will also be installed in the area of concern located in the northwest portion of the McBride Site where free product was encountered. These wells will be utilized to further delineate the area where free product is present. These wells will be gauged for the presence of free product; analytical sampling is not anticipated at this time. Amendment to Environmental Testing Services Contract w/Terracon February 4, 2005 Page 5 TASK 1100—Building Demolition and Initial Remediation Specifications To solicit contractor bids for the demolition of the on-site structures and implement the initial remediation elements, a complete bid specification will be prepared. This bid specification will address the following efforts: • Asbestos Abatement 1 • Building Demolition (Including Concrete Foundations and Special Structures) • Underground Storage Tank Removal • Removal and Disposal of Drummed materials and Miscellaneous Debris • Environmental Remediation (Areas of Gross Contamination) • Site Controls and Utilities • Site Grading and Removal of Visually Impacted Surface Soils The bid specification will be prepared to include the City of Elgin's standard general conditions and agreement forms to address contracting issues such as bonding, insurance, EEO participation and union wage scales. As part of this task, Terracon will update the project cost estimate based on the final specifications, provide coordination with City staff to publicly bid the work, attend one pre-bid meeting with prospective contractors (site walk through), and review and tabulate the bids received. Future work associated with the site will include environmental field oversight during the demolition work. During the demolition process, Terracon anticipates the need to conduct sampling and assessment of various subsurface features such as pits, floor drains, pipe chases and similar items that cannot cost-effectively be investigated prior to building demolition. Following the remediation, the City should expect that the IEPA will require confirmation sampling to ensure that the remediation objectives are met. Effort and costs to conduct this work is not included in this scope of work. SCHEDULE • Bid specifications will be prepared for release to contractors by February 18, 2005. • Additional site investigation will be conducted from February 15 to April 15, 2005.
