Helwig, City Manager SUBJECT: Change Order No. 2 for Soil Remediation Oversight Services at the Law Enforcement Facility Site PURPOSE The purpose of this memorandum is to forward to the Mayor and City Council Change Order No. 2 for soil remediation over- sight at the law enforcement facility site. BACKGROUND In June of 1993, the City and Environmental Science and Engi- neering (ESE) entered into an agreement which called for ESE to determine the extent of contamination on the police facili- ty property and to develop a methodology to remediate the site. Environmental tests were done and a Corrective Action Plan was submitted to the- Illinois Environmental Protection Agency (IEPA) in November of 1993. IEPA reviewed the submittal and required additional borings and monitoring wells to be placed on the site. Change Order No. 1 was approved in March of 1994 . The change order authorized the additional soil boring and monitoring wells. It also included funds for developing specifications for the removal of 5,000 cubic yards of soil from the site as well as funding for the preliminary design of the in-ground remediation system. The change order was for $44,496 . It brought the total contract amount to $87,335.00. Change Order No. 2 is required to complete the following additional tasks related to the site: Task 1 - Field Oversight of Contaminated Soil Removal ESE personnel will be on-site during the soil removal operations to direct the removal of contaminated materi- als as identified through the subsurface investigations Change Order No. 2 November 8, 1994 Page 2 previously performed. ESE will screen soils with a photoionization detector (PID) which has a non-compound specific detection limit of one part per million of organic vapor. Based upon the results of PID measure- ments, ESE field personnel will direct the excavation contractor to remove those soils exhibiting contamina- tion. Once the excavation has progressed to a point where the PID no longer detects organic vapors and visual observa- tions indicate clean soil conditions, ESE will direct the excavation contractor to cease soil removal activi- ties . ESE will collect soil samples at intervals along the sidewalls and floor of the excavation. Soil samples will be placed in an iced cooler and shipped to ESE' s Peoria, Illinois laboratory for analysis under Chain of Custody procedures . If the soil samples confirm that the remaining soils are within clean up objectives for the site, then the excava- tion work will be complete. If clean soil conditions are not documented, ESE will direct the excavation con- tractor to resume soil removal activities as necessary and warranted based on the laboratory results . During the soil remediation program, ESE personnel will observe the Contractor' s operations and procedures to ensure compliance with the specifications . This task will include monitoring the quantities of soil removed by the excavation contractor and any unit quantities as specified in the contract documents . ESE will review soil disposal manifests prior to signature by a represen- tative of the City. ESE will advise the City of any work performed that does not conform to the contract documents . Task 2 - Soil Sample Analysis Soil samples will be analyzed for the presence of benzene, ethylbenzene, toluene and xylenes (BETX) in accordance with USEPA method 8020 and polynuclear aromat- ics (PNAs) in accordance with USEPA method 8310. A maximum of 20 soil samples will be analyzed. A total of six of the 20 samples are anticipated to be analyzed on a rush turnaround basis (48 hours) to accommodate the Contractor' s field schedule. Change Order No. 2 November 8, 1994 L Page 3 Task 3 Construction Services/Project Management ESE will evaluate bids received from contractors and provide recommendations for award. ESE will attend one pre-construction meeting to schedule and coordinate the planned -soil excavation work with the selected Contrac- tor and City representatives . ESE will review applications for payment from the excava- tion Contractor and make recommendations for payment. ESE will make a final inspection of the site to verify the completion of the Contractor' s work and issue a notice of substantial completion. ESE personnel will participate in meetings and provide consultation services necessary to coordinate this as- pect of the work with the overall remediation program and implementation of the police station construction with the City' s Construction Manager and Architect. A total of three meetings are anticipated for this task. Task 4 - Report Preparation Following the completion of soil excavation field activi- ties and the return of laboratory results, ESE will prepare documentation summarizing the excavation activi- ties completed, the results of laboratory analyses, information regarding disposal of contaminated materi- als, and conclusions and recommendations . This report will be written so that it can be integrated into the Corrective Action Completion Report following the comple- tion of other corrective action activities planned for the site. FINANCIAL IMPACT The change will result in a $24,725 increase in the contract with ESE from $87,335 to $112,060. The costs associated with the soil remediation oversight should be eligible for reim- bursement from IEPA LUST funds. Expenses related to this project will be charged to the 1991 G.O. Bond Fund (391-0000-795-92 .32, Project 039503) , budgeted for site devel- opment and preparation. COMMUNITY GROUPS/INTERESTED PERSONS CONTACTED None. LEGAL IMPACT None.
