SUPPLEMENTARY INFORMATION: Table of Contents I. Introduction [[Page 26464]] II. NPL Deletion Criteria III. Deletion Procedures IV. Basis for Intended Site Deletion I. Introduction The U.S. Environmental Protection Agency (EPA) Region V announces its intent to delete the Southside Sanitary Landfill Site from the National Priorities List (NPL), which constitutes Appendix B of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), and requests comments on the proposed deletion. The EPA identifies sites that appear to present a significant risk to public health, welfare or the environment, and maintains the NPL as the list of those sites. Sites on the NPL may be the subject of remedial actions financed by the Hazardous Substance Superfund Response Trust Fund (Fund). Pursuant to Section 300.425(e)(3) of the NCP, any site deleted from the NPL remains eligible for Fund-financed remedial actions if the conditions at the site warrant such action. The U.S. EPA will accept comments on this proposal for thirty (30) days after publication of this notice in the Federal Register. Section II of this notice explains the criteria for deleting sites from the NPL. Section III discusses procedures that EPA is using for this action. Section IV discusses the history of this site and explains how the Site meets the deletion criteria. Deletion of sites from the NPL does not itself create, alter, or revoke any individual's rights or obligations. Furthermore, deletion from the NPL does not in any way alter U.S. EPA's right to take enforcement actions, as appropriate. The NPL is designed primarily for informational purposes and to assist in Agency management. The Site can be restored to the NPL, if at anytime a significant release from the Site poses a threat to the surrounding environment or human health. II. NPL Deletion Criteria The NCP establishes the criteria the Agency uses to delete sites from the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted from the NPL where no further response is appropriate. In making this determination, U.S. EPA will consider, in consultation with the State, whether any of the following criteria have been met: (i) Responsible parties or other persons have implemented all appropriate response actions required; or (ii) All appropriate Fund-financed responses under CERCLA have been implemented, and no further response action by responsible parties is appropriate; or (iii) The Remedial Investigation has shown that the release poses no significant threat to public health or the environment and, therefore, remedial measures are not appropriate. III. Deletion Procedures Upon determination that at least one of the criteria described in 300.425(e) has been met, U.S. EPA may formally begin deletion procedures once the State has concurred. This Federal Register notice, and a concurrent notice in the local newspaper in the vicinity of the Site, announces the initiation of a 30-day comment period. The public is asked to comment on U.S. EPA's intention to delete the Site from the NPL. All critical documents needed to evaluate U.S. EPA's decision are included in the information repository and the deletion docket. Upon completion of the public comment period, if necessary, the U.S. EPA Regional Office will prepare a Responsiveness Summary to evaluate and address comments that were received. The public is welcome to contact the U.S. EPA Region V Office to obtain a copy of this responsiveness summary, if one is prepared. If U.S. EPA then determines the deletion from the NPL is appropriate, final notice of deletion will be published in the Federal Register. IV. Basis for Intended Site Deletion The Southside Sanitary Landfill (the Site) is located on the west bank of the White River, where it joins with Eagle Creek, one-half mile south of the intersection of Kentucky Avenue and Warman Road located in Indianapolis, IN. Landfill operations at this site began in 1971. The initial operation was based on a cut and fill procedure. A trench, approximately 100 feet wide and 8 feet deep, was excavated, filled with solid waste, and then covered. After trenching was found to expose sand and/or gravel pockets, a compacted soil liner was placed under the fill. In 1981, operations switched to the area method of filling, which consists of dumping, spreading, and covering. Groundwater monitoring for contamination at the landfill began in 1973 when the United States Geological Survey installed 224 wells around the portion of the landfill permitted to accept waste. In 1984, U.S. EPA contractors conducted a site inspection at the facility to acquire the data needed for a Hazard Ranking System scoring. On-site wells sampled indicated the presence of heavy metals in the groundwater at the facility. The groundwater sampling conducted at the Site can be divided into two major categories for the purpose of groundwater quality analyzed: (1.) The routine parameter analysis conducted from 1973-1984, which included only a few inorganic and organic parameters, and (2.) Expansion of the routine parameter analysis by the State agency monitoring programs to include additional inorganic and organic parameters. These monitoring programs served as an independent check on the landfill's quarterly water data. The metal analyses from all wells sampled in 1984 were below Maximum Contaminant Levels (MCLs). Only the iron and manganese results exceeded secondary MCLs in both upgradient and downgradient wells. In 1985, the operators signed an Agreed Order with the Indiana State Board of Health to correct drainage problems identified on the landfill surface. The Agreed Order, which also permitted vertical expansion of the facility, served as the operating permit for the Site until a Solid Waste Facility Permit FP #49-1 was issued by the State in July 1996. The Site was scored and nominated for the NPL in 1986, and finalized on the NPL in March 1989. The first public meeting was conducted at the beginning of the Remedial Investigation (RI) process in September 1992, at the Indiana Government Center South located in Indianapolis. The final public meeting was conducted in June 1995, after completion of the RI and development of a Proposed Plan for Remedial Action. Before the public meeting, IDEM prepared Fact Sheets describing site activities which were mailed to the local residents, officials and media for information. IDEM as the lead agency in consultation with U.S. EPA, set a public comment period from June 19, to July 19, 1995. This comment period included a public meeting where U.S. EPA and IDEM discussed the RI report findings, the Proposed Plan, answered any questions, and received formal comments. The Record of Decision (ROD) was signed by IDEM's Commissioner on September 14, 1995. The selected remedy for this site is no further action. The Site operators had previously untaken specific remedial measures in an attempt to decrease any threat of release of contaminants from the Site. The measures included installation of a hydraulic cut-off barrier and leachate collection system. These actions were undertaken to comply with the requirements of an Agreed Order (AO) signed between the South Side Landfill, Inc., under Cause [[Page 26465]] No. N-243, approved on November 25, 1986. The AO provided for construction and installation of a hydraulic cut-off barrier and leachate collection system. Additionally the AO required the following: a performance monitoring system, cover and grading requirements, operating procedures, meeting closure and post-closure procedures and requirements, and the establishment of both closure and post-closure funds. This site is currently regulated under a State issued permit (FP #49-1). The remedial action requirements as stated in the Agreed Order (dated February 1990) have been incorporated into the current permit, which requires regular inspections and monitoring schedules for a 30- year post-closure period of the landfill. The permit (FP #49-1) was issued under the state authority IC 13-15-7. The Remedial Investigation results and risk assessment evaluation established that the chemical contamination discovered at the Site, with current remedial measures in place, does not pose an unacceptable risk to the environment and human health. However, as waste was left in place and contained, a 5-year review of site status which includes a physical inspection of the Site and a review of monitoring data is recommended. EPA, with concurrence from the State of Indiana, has determined that all appropriate Fund-financed responses under CERCLA at the Southside Sanitary Landfill Superfund Site have been completed, and no further CERCLA response is appropriate in order to provide protection of human health and the environment. Therefore, EPA proposes to delete the Site from the NPL. Dated: May 1, 1997. Michelle D. Jordan, Acting Regional Administrator, U.S. EPA, Region V.
