Current Site StatusCurrently, construction is complete at the Lord-Shope Landfill, and the remedy is operational and functional. In August 2002, EPA approved a Lord Corporation request to reduce the frequency of the monitoring of the levels of the ground water in the site wells from quarterly to semi-annually. No increases in contamination have been determined, and no residential wells have been affected by the contamination. A third Five-Year Review of the site was conducted in September 2009 and found that the Site remained protective of human health and the environment.
Site DescriptionThe Lord Shope Landfill, located in Erie County, Pennsylvania had approximately four million cubic feet of waste disposed on the privately owned five-acre site between 1959 and 1979. Wastes deposited on the landfill consisted principally of solid debris, and included rubber scrap, organic and inorganic chemicals, solvents, cooling oils, acids, and caustic agents. Land use in the immediate vicinity includes field crop agriculture, a golf course, orchards, vineyards, and wooded areas. The nearest residences are situated several hundred feet from the site. Approximately 125 people reside within one mile of the site, and about 5,700 people live within three miles of the contamination area. Elk Creek, into which the site runoff discharges, has a water intake located approximately 4,800 feet downstream of the contamination area. The water from this intake is used to irrigate food crops.
Site ResponsibilityThe Site is being addressed through potentially responsible party (PRP) actions under the oversight of federal and state agencies.
NPL Listing HistoryOur country's most serious, uncontrolled, or abandoned hazardous waste sites can be cleaned using federal money. To be eligible for federal cleanup money, a site must be put on the National Priorities List. This site was proposed to the list on December 30, 1982 and formally added to the list September 8, 1983.
Threats and ContaminantsDue to the spillage or disposal of liquid wastes and leaching of contaminants, the soils, landfill materials, and groundwater are contaminated with VOCs and various heavy metals including lead. Arsenic and copper have been identified in off-site surface water, although not at significant levels. Long-term risks are posed by the potential for consumption of contaminated groundwater. Currently, there are no drinking water wells in the area of contamination. Direct contact with landfill materials and soil is limited by a cap, a fence, and re-vegetation of the area.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
In 1983, Lord Corporation, the potentially responsible party (PRP) for the Site, removed contaminated exposed drums, placed 20,000 gallons of landfill leachate into containers and removed it, regraded and capped the landfill with a synthetic liner, and installed a subsurface wall to divert ground water from coming in contact with contaminated materials in the landfill. These actions were pursuant to a Consent Order with the Pennsylvania Department of Environmental Resources.
In 1987, the Environmental Protection Agency (EPA) and Lord Corporation entered into a Consent Order for the Remedial Investigation/Feasibility Study (RI/FS) of the site. In 1990, EPA selected the remedy for cleanup of the entire Site that included removal of volatile organic compounds (VOCs) from the landfill materials and surrounding soils through in-situ vapor stripping and thermal treatment, treatment of contaminated ground water by pre-treatment for iron and other metals, removal of the VOCs, and discharge of treated groundwater to a nearby tributary of Elk Creek.
The design of the cleanup technologies was finalized in July 1994, and construction began in the fall of 1994. The in-situ vapor stripping component of the remedy became operational in November 1995. The groundwater treatment component was completed and began operating in June 1996. EPA classified the site as "construction complete" in September 1996. The groundwater treatment is expected to reach cleanup goals in 40 years.
EPA's five-year reviews of the remedy conducted in 1999, 2004 and 2009 determined that the remedy remained protective of human health and the environment.
Lord Corporation continues to monitor the groundwater, including the wells of nearby residences, the results are presented in an annual groundwater report. The most recent report (April 2012) continues to indicate that no residential wells have been affected by the contamination
In August 2002, EPA approved a Lord Corporation request to reduce the frequency of the monitoring of the levels of the ground water in the site wells from quarterly to semi-annually. In late 2007, EPA approved Lord Corporation's request to cycle the ISVS operation in six month on/off intervals in an attempt to optimize the thermal oxidizer unit's performance, improve extraction of VOCs from the landfill and reduce energy usage In April 2008 Lord Corporation installed and brought on-line a new thermal oxidizer unit. The Third Five-Year Review of the site was finalized on September 10, 2009 and found the Site is protective of human health and the environment. In conjunction with PADEP, EPA continues to review the Site's environmental monitoring data and reports. The Fourth Five-Year review will be performed no later than September 12, 2014.
