C-l TC-1 1.0 Overview of Community Involvement Plan The United States Environmental Protection Agency (EPA) developed this Community Involvement Plan (CIP)1 in preparation for community involvement activities to be conducted during the Remedial Investigation/Feasibility Study (RI/FS) at the Mississippi River Pool #15 (MRP 15) Site near Riverdale, Iowa, in accordance with EPA’s Superfund Program. This document provides information about community concerns and presents a plan to enhance communication between the public and EPA throughout the Superfund process. The objective of EPA’s Superfund community involvement program is to involve the public in activities and decisions related to the cleanup of Superfund sites. The Superfund community involvement program promotes two-way communication between members of the public and EPA. EPA recognizes, in its decision-making process, the importance of actively soliciting comments and information from the public. Public input can be useful in two ways: • Communities are able to provide valuable information on local history, citizen involvement, and site conditions • Communities that express concerns assist EPA in recognizing the unique characteristics of each site community and in developing a response that more effectively addresses specific community needs This CIP consists of the following sections: • Overview • Site Background • Community Background • Community Involvement Program • Activities and Timeline This CIP contains the following appendices: • A glossary of acronyms and technical terms • A list of locations for public meetings and site information repository • A list of contacts and interested groups 'Words appearing in boldface type are defined in Appendix A, Glossary. 1-1 1.1 A Brief Explanation of the Superfund Process at the MRP15 Site In 1980, the United States Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which established the Hazardous Substance Response Trust Fund (the Superfund) and authorized EPA to respond directly or compel Potentially Responsible Parties (PRPs) to respond to releases of hazardous substances that may endanger public health and/or the environment. Congress amended and reauthorized the Superfund law in October 1986 under the Superfund Amendments and Reauthorization Act (SARA). In the event that no PRPs are identified, or the PRPs do not agree to conduct the investigations and cleanup, then the work is conducted by EPA. At the MRP 15 site, the Aluminum Company of America (Alcoa) was identified as a PRP and entered into a 1990 Administrative Orders on Consent (AOC) that was amended in 1996. The RI/FS phase in the Superfund process includes investigation and risk assessment activities (i.e., the RI) and an evaluation of cleanup alternatives (i.e., the FS). The 1990 AOC required investigation of sediments in drainageways (referred to as outfalls) on the Alcoa facility, investigation of sediments inMRP15, arisk assessment, and biennial sampling and polychlorinated biphenyl (PCB) analyses of fish from MRP15. Collectively, these various investigative activities comprise the RI. The 1990 AOC was amended in 1996 to modify the fish collection locations and type of species to be collected, to allow Alcoa to perform the MRP 15 risk assessment for EPA review and approval, and to establish a Special Account for reimbursement of oversight costs incurred by EPA. At the completion of the RI, EPA will determine if a Feasibility Study (FS) is necessary. If so, Alcoa will present an evaluation of cleanup alternatives in the FS and EPA will prepare a Proposed Plan to summarize the cleanup alternatives and identify a preferred alternative. Following a public comment period on the Proposed Plan, EPA will prepare a Record of Decision (ROD) to document the selected cleanup remedy. The remedy, as described in the ROD, will be implemented during the Remedial Design/Remedial Action (RD/RA) phase of the Superfund process. 1-2 2.0 Site Background 2.1 Site Location and Description The Aluminum Company of America (Alcoa)-Davenport Works is located in Sections 23, 24, 25, and 26 of Township 78N, Range 4E, Scott County, Iowa. The Alcoa facility occupies 445 acres in the Town of Riverdale, near the Quad Cities (Davenport and Bettendorf, Iowa, and Moline and Rock Island, Illinois) and is adjacent to MRP15 (see Site Location Maps). MRP15 encompasses approximately 10 miles of the Mississippi River, bounded by Federal Lock and Dam 14 on the upriver end and Federal Lock and Dam 15 on the downriver end. MRP 15 extends from river mile 482.9 to 493.2, and the Alcoa facility is located at approximately river mile 488.9. 2.2 Site History Historical use of PCB-containing oils and products used at the Alcoa-Davenport Works has resulted in releases to surface water and sediments of MRP 15. Consequently, areas within the Alcoa facility (Alcoa site) and portions of MRP 15 (MRP 15 site) have been the subject of investigations and evaluations pursuant to a series of AOCs between Alcoa and EPA. 2.3 EPA Activites In 1983, EPA’s National Enforcement Investigation Center (NEIC) sampled fish from MRP15 to assess concentrations of PCBs. In fish collected adjacent to the Alcoa facility, composited fillets of common carp contained up to 4.2 parts per million (ppm) total PCBs and channel catfish composites contained up to 1.1 ppm total PCBs. These levels were below the Food and Drug Administration (FDA) tolerance level of 5 ppm. In 1987, EPA conducted limited fish sampling adjacent to the former waste oil lagoon and found carp to have average concentrations of 4.8 ppm, which now exceeded the revised FDA tolerance level of 2 ppm. In 1988, Alcoa conducted a more extensive fish sampling event that indicated total PCB concentrations ranged from 2 to 8 ppm. Due to fillet concentrations exceeding the FDA tolerance level of 2 ppm, the State of Iowa Department of Natural Resources (Iowa DNR) evaluated this data and issued a fish consumption advisory for carp on the Iowa side of the Mississippi River in Pool 15. In addition, this advisory notified the public that some catfish in MRP 15 may also contain levels of PCBs above the FDA tolerance level. In April 1990, Iowa DNR issued a second fish consumption advisory for carpsuckers (also referred to as white carp) taken along the Iowa side of
