The 15-acre Summit National site is located in Portage County, Ohio, on a former coal strip mine containing a coal wash pond and a coal stockpile. From 1974 to 1978, the site was used as a waste disposal facility and received such wastes as oils, resins, paint and metal plating sludges, flammable solvents and chlorinated solvents. Two surface water ponds and an incinerator were also located onsite. The facility received liquid wastes which were stored in drums, an open pit, or in bulk tanks. Some wastes were incinerated, others were buried and some were dumped on the soil. The groundwater, soil and surface water were contaminated with volatile organic compounds (VOCs), phenols, phthalates, polychlorinated biphenyls (PCBs) and heavy metals including arsenic, chromium, and cadmium. About 4,500 people live within three miles of the site. Surface water flow from the site goes to the Berlin Lake Reservoir which is a standby water supply for the city of Youngstown.
The U.S. Environmental Protection Agency (EPA) proposed the site to the National Priorities List (NPL) in December 1982 and finalized the site on the NPL in September 1983.
Site ResponsibilityThis site is being addressed through federal, state, and potentially responsible parties' actions.
Threats and ContaminantsThe groundwater is contaminated with various VOCs, phenols, and phthalates. VOCs, phenols, and heavy metals including arsenic, cadmium and antimony were contaminating the soil. The surface water was contaminated with VOCs, phenols, polycyclic aromatic hydrocarbons, PCBs, and heavy metals including arsenic and chromium. The contaminated groundwater could pose a health risk if accidentally touched or ingested.
In 1980, EPA, the Ohio Environmental Protection Agency (OEPA), and the potentially responsible parties (PRPs) removed drums, tanks and a small amount of soil from the site. In 1987, EPA removed liquids and strengthened dikes to prevent contaminants from overflowing the ponds and flowing to the Berlin Reservoir. A Consent Decree between EPA, OEPA and the PRPs was entered on June 11, 1991, for the design and cleanup of the site. The PRPs completed the design and then took the following actions at the direction of the Agencies: in 1994, the PRPs dredged contaminants from the adjacent drainage ditches, and in 1995, the PRPs excavated and incinerated 21,000 tons of contaminated soils and sediments, excavated and took offsite for disposal 484 drums, and constructed a collection trench and a treatment plant for the groundwater. About 25 million gallons of contaminated water have been treated. Following those actions, contaminant levels steadily declined at the site. Based on these findings, the PRPs submitted a proposal for natural attenuation, but it did not meet the Agency's standards. The PRP is continuing to collect and submit data for the groundwater treatment system.
The first five-year review for the site was completed in September 1998, and the second five-year review was completed in September 2003. The third five-year review was completed on August 25, 2008, and concluded that the remedy remains protective of human health and the environment. A fourth five-year review is scheduled to be completed by August 2013.
