Task 2d—Bidding Support <br /> INTERA will provide support for preparation of bidding documents, bidding of the <br /> construction, and recommendation for award of the construction contract. INTERA will meet <br /> with staff to review the City's procurement procedures and requirements and will prepare <br /> complete bidding documents based on the City's required front-end documents, technical <br /> specifications,design plans, and other information. INTERA will provide assistance to the City <br /> in advertising for bids, conducting a pre-proposal meeting and site visit, and responding to <br /> requests for information from bidders,and preparation of addenda. <br /> INTERA will review and evaluate bids received based on criteria established in advance with <br /> City staff. We will prepare a memorandum summarizing the bid analysis and make a <br /> recommendation for award to the bidder that will provide the best performance and value <br /> to the City. <br /> Task 2. Rhodes Landfill <br /> The scope of work for the Rhodes Landfill (Landfill) is to conduct a review of the regulatory and <br /> environmental status of the Landfill closure and determine what potential liabilities exist if Lake <br /> Toko was acquired by the City as an additional water supply source. The Landfill was closed in <br /> 1992 and post-closure monitoring began in 2003. The 15-year post-closure monitoring should <br /> have ended in 2018, however, the Illinois EPA (ILEPA) required additional monitoring to <br /> continue for an unspecified period. As noted in the 2019 Report, numerous emerging <br /> contaminants(e.g., PFAS) had not yet been sampled but may have been since 2019. <br /> Task 2a—Collect data and evaluate potential risks <br /> INTERA will contact the ILEPA to request permits, additional data, correspondence, and <br /> reports that exist related to the Landfill. Of particular interest will be a) any older data that <br /> was not uncovered during our prior review, b) any new data collected since our previous <br /> review, and c) the physical characteristics and current regulatory status of the Landfill. <br /> INTERA will also seek updated information regarding ILEPA's concerns about the adequacy of <br /> the monitoring well network and the agency's position regarding continued monitoring. In <br /> addition, INTERA will obtain documentation of any groundwater quality assessment program <br /> that may have been implemented and the data associated with this program if it exists. The <br /> volume of information available and the time required for the ILEPA to respond to the data <br /> request is unknown at this time. The project budget assumes a maximum of 80 hours for <br /> review of data and documents. <br /> INTERA will review the available information and provide a qualitative assessment of the <br /> potential risks to the City from the Landfill if the purchase of Lake Toko proceeds. Collective <br /> groundwater monitoring data will be evaluated to determine if any of the existing data <br /> 3 <br /> Last Revised:4/4/2022 <br />
