Site DescriptionThe New Lyme Landfill Superfund site is on Dodgeville Road, approximately twenty miles south of the city of Ashtabula, Ohio. The landfill began operations in 1969. The site was initially managed by two farmers. The landfill was licensed by the state of Ohio, and operations were taken over by a licensed landfill operator in 1971. During its years in operation, the New Lyme Landfill received household, industrial, commercial, and institutional wastes and construction and demolition debris. Fifty-five gallon drums of cyanide sludge are believed by Ohio Environmental Protection Agency (OEPA) to have been buried at the site. Documents indicate that wastes at the New Lyme Landfill site include: coal tar distillates, asbestos, coal tar, resins and resin tar, paint sludge, oils, paint, chlorinated solvents, 2,4-D and laboratory chemicals. In August, 1978, the landfill was closed by the Ashtabula County Health Department due to recurrent violations of the license, the Ohio Revised Code, and the Ohio Administrative Code. The site lies entirely within the Lebanon Creek Watershed. The northern portion of the site drains directly into Lebanon Creek. The remainder of the site drains southward to an unnamed tributary of Lebanon Creek. Lebanon Creek drains into Rock Creek, upstream of Lake Roaming Rock, a public water supply.
Site ResponsibilityThis site is being addressed through federal, state, and potentially responsible parties' actions.

Cleanup ProgressIn September 1985, the United States Environmental Protection Agency (EPA) issued a Record of Decision (ROD) which included:
- Installation of a Resource Conservation and Recovery Act cap over the landfill.
- Installation of extraction/treatment wells around the perimeter of the landfill to dewater the landfill and eliminate leachate production. The wells will operate indefinitely.
- Onsite treatment of contaminated groundwater and leachate using rotating biological contractors, sodium hydroxide precipitation, and granulated activated carbon until leachate is no longer produced and treatment becomes unnecessary (estimate of 15 years).
- Onsite consolidation of contaminated sediment.
- Gas control, fence, groundwater monitoring.
In November 1999, EPA issued an amended ROD for the site. The amended ROD required the shutdown of the on-site groundwater treatment facility, long-term groundwater monitoring program, a contingency plan, and continued operation and maintenance activities of the cap, leachate controls and continued site security. In 2001 and 2002, the PRPs began measures to implement the amended ROD components. On July 27, 2001, the groundwater extraction/treatment system was deactivated. Weekly site security visits and quarterly groundwater sampling continued at the site throughout 2001 and 2002.
The second five-year review for the site was completed on March 5, 2003, The five-year review indicated that the site had some issues which included the following:
- low spots or subsidence of the landfill cap along the earstern portion of the site;
- inadequate monitoring data to determine migration of contaminants within the deep aquifer;
- high arsenic level at the site; and,
- lack of analytical projections to predict the length of time until ground water cleanup goals will be achieved.
To address these site issues, EPA planned to take the necessary steps to ensure that the low spots along the landfill cap were repaired. These repairs were completed in 2004.
The sampling program for some ground water monitoring wells will be modified. Analytical projections to determine the length of time until ground water cleanup goals are achieved will be conducted. Also, the high aresenic levels at the site will be further investigated.
The third five-year review for the Site was signed on March 4, 2008. The five-year review found that the remedy components of the Amended ROD are operating as intended and are considered to be protective of human health and the environment in the short-term. The remedy is expected to be protective of human health and the environment in the long-term upon attainment of all cleanup standards and once institutional controls are fully implemented at the Site. In the interim, exposure pathways that could result in unacceptable risks are being controlled by preventing exposure to, or the ingestion of, contaminated groundwater.
The next five-year review is due by March 2013.
