INTRODUCTION The purpose of a Five-Year Review (FYR) is to evaluate the implementation and performance of a remedy in order to determine if the remedy is and will continue to be protective of human health and the environment. The methods, findings, and conclusions of reviews are documented in FYR reports such as this one. In addition, FYR reports identify issues found during the review, if any, and document recommendations to address them. The Illinois Environmental Protection Agency (Illinois EPA), in consultation with the United States Environmental Protection Agency (EPA), is preparing this FYR pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 121, consistent with the National Oil and Hazardous Substances Contingency Plan (NCP)(40 CFR Section 300.430(f)(4)(ii)), and considering EPA policy. This is the fourth FYR for the Adams County Quincy Municipal Landfills #2 and #3 (Adams County Landfill) Superfund Site (Site). The triggering action for this statutory review is the completion date of the previous FYR, which was March 1, 2013. The FYR has been prepared due to the fact that hazardous substances, pollutants, or contaminants remain at the Site above levels that allow for unlimited use and unrestricted exposure (UU/UE). The Site consists of one, Site-wide Operable Unit (OU), which will be addressed in this FYR. The Adams County Landfill Superfund Site FYR was led by Brian Conrath of Illinois EPA. Participants included Karen Cibulskis of EPA. The official notification of initiation of the FYR process was issued to the potentially responsible parties (PRPs) on March 22, 2017. The FYR began on March 22, 2017. Site Background The Adams County Quincy Municipal Landfills 2 & 3 Site is located in a rural area on Rock Quarry Road (formerly known as Old Broadway Road) south of Illinois Route 104 approximately 5 miles east of the city of Quincy, Illinois. The Site’s northern limits are bounded by Rock Quarry Road and residences, the eastern boundary is adjacent to a dairy farm and residence, the southern limit is bounded by a wooded tract, and the western boundary is bordered by a private lane and a residence. The landfill area covers approximately 37 acres of the 56-acre property Site. Approximately 30 acres of the landfilled area are covered by a landfill cap with a leachate collection system to remediate issues associated with leachate and the resulting contaminant impacts to groundwater. The Site was used as a pasture for livestock prior to the initiation of landfill operations in 1967. In January 1967, the Adams County Health Department approved a landfill development permit requested by Ronald Thomas. Illinois EPA issued Ronald Thomas and Marion Neill a permit to operate a landfill at the Site in March 1971. The city of Quincy leased the landfill from Ronald Thomas in September 1972. Illinois EPA issued a permit to the city of Quincy to operate the landfill in January 1973. Illinois EPA issued permits to expand the size of the landfill to the city of Quincy in 1974 and in 1975. 3 The city operated the Site until August 1978, then purchased the Site from Ronald and Sarah Thomas in April 1982. The Site is expected to remain a closed landfill in perpetuity. Additional background information about the Site can be found in Appendix B and in the 2013 FYR.
