Sidney Landfill, Five-Year Review Report, June 2014 [PDF 87 KB, 1 pp]

The U.S. Environmental Protection Agency (EPA) added the 74-acre Sidney Landfill site to the Superfund National Priorities List (NPL) in March 1989, because hazardous chemicals were found in the site’s soil and ground water. The site is located on the western slope of Richardson Hill, which is on the east side of Richardson Hill Road and approximately 10 miles southeast of Sidney, New York. The Richardson Hill Road Landfill site, which is also on the NPL, is located directly across the street. From 1967 to 1972, several discrete areas (approximately 20 acres in total) in different part of the site were filled with municipal and commercial waste, including waste oil from the Scintilla Division of Bendix Corporation (predecessor to Honeywell International, Inc. and Amphenol Corp.). Investigations revealed the presence of elevated levels of volatile organic compounds and polychlorinated biphenyls in the soil and ground water, which posed a threat to human health and the environment.

Based on the results of a remedial investigation and feasibility study to determine the nature and extent of the contamination at the site and the identification and evaluation of cleanup alternatives, the EPA selected a cleanup plan for the site in 1995. The cleanup plan called for the placement of caps over several disposal areas and the extraction and treatment of contaminated ground water. The installation of the caps was completed in 1999. Based on the results of ground water testing and sampling, it was determined that the ground water extraction and treatment system already operating at the nearby Richardson Road Landfill Superfund site was capturing the contaminated ground water from the Sidney Landfill site, so a ground water extraction and treatment system at the Sidney Landfill site would not be needed. This finding was documented in a September 2004 Explanation of Significant Differences. 

Under Superfund, the EPA conducts reviews every five years at sites to ensure that the implemented cleanups are functioning as intended and continue to protect human health and the environment. The EPA completed five-year reviews for the Sidney Landfill site in 2004, 2009 and 2014 concluding that the implemented actions continue to be effective and protective.
