Current Site Status
The cleanup of the Hranica Landfill Superfund Site is now complete and the Site was deleted from the National Priorities List on September 18, 1997. EPA provides oversight of routine groundwater monitoring and cap maintenance activities conducted by the Potentially Responsible Parties (PRPs).
The fourth Hranica Five Year Review was signed on April 16, 2012. The following Protectiveness Statements were presented in the Five Year Review:
OU-1 – Soil
The remedy for OU-1 – Soil at the Hranica Landfill Site is protective of human health and the environment in both the short and long term due to the installation of a low-permeability cap over contaminated soil, installation of a perimeter fence, and implementation of institutional controls providing notice that hazardous substances are present at the Site and prohibiting disturbance of the cap.
OU-2 – Groundwater
The remedy for OU-2 – Groundwater at the Hranica Landfill Site is protective of human health and the environment in both the short and long term due to groundwater, surface water, and residential well monitoring and implementation of institutional controls providing notice that hazardous substances are present at the Site and prohibiting the installation of onsite wells. The protectiveness of the OU-2 remedy is enhanced by the connection of all nearby downgradient residences to public water.
The Site-wide remedy at the Hranica Landfill Site is protective of human health and the environment in both the short and long term. Physical construction of the remedy is complete, operation and maintenance is being conducted in accordance with the OU-1 and OU-2 RODs, and institutional controls have been implemented.
The Five Year Review also indicated that locking well caps on multiple onsite monitoring wells were damaged and needed to be replaced. The well caps were replaced by the PRPs in late April 2012.
Site DescriptionThe Hranica Landfill, located in Butler County, Pennsylvania, consists of approximately 15 acres. The privately owned landfill operated from 1966 to 1974 and received both municipal and hazardous wastes. By 1981, the site contained over 19,200 drums and other larger vessels of waste consisting of chlorinated solvents, paint pigments, and metal sludges. Metals in soils were identified as the primary contaminant of concern at the site. Approximately 4,000 people live within a 3-mile radius of the site.
Site ResponsibilityThe site was addressed through PRP action under EPA oversight.
NPL Listing HistoryOur country's most serious uncontrolled or abandoned hazardous waste sites can be cleaned using federal money. To be eligible for cleanup money, a site must be put on the National Priorities List (NPL). This site was proposed to the National Priorities List on December 30, 1982 and was formally added on September 8, 1983, making it eligible for federal cleanup funds. The site was deleted from the NPL on September 18, 1997.
Threats and ContaminantsGroundwater at the site was contaminated with heavy metals and volatile organic compounds (VOCs), soil was contaminated with heavy metals, VOCs, Polychlorinated biphenyls (PCBs) and phenols, and surface water was contaminated with VOCs, PCBs, and phenols. Following a Removal Action in 1984, subsequent investigations indicated that the surface water springs were no longer contaminated. The primary risk at the site was identified as direct contact with or accidental ingestion of contaminated soils.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
In 1983 and 1984, all drums and visibly contaminated soils were removed from the site by the PRPs, Aluminum Company of America, Inc. (ALCOA) and PPG Industries, Inc. (PPG). PPG entered into a Consent Order with EPA on March 13, 1987 requiring that PPG conduct a Phase II Comprehensive Site Investigation, an Endangerment Assessment (EA), and a Feasibility Study (FS) for the Site. The final FS Report was submitted in May 1990. A Record of Decision (ROD), documenting the remedy for OU-1 was issued on June 29, 1990. Following the completion of a Groundwater Verification Study, a No Further Action ROD was issued for OU-2 on May 26, 1994. The remedy selected by EPA in the ROD consisted of the installation of an eight-foot fence around the perimeter of the Site to prevent trespassing, a long-term ground water monitoring program of both on-site and off-site wells, placement of a soil cap over areas containing lead-contaminated soils, and institutional controls to prevent the excavation or disturbance of the soil cap to prohibit the development of water supply wells onsite.
A Consent Decree to perform the Remedial Design and Remedial Action was signed by ALCOA and PPG in June of 1991. Remedial Design began in February 1992 and the Final Design was approved in March 1993. The Remedial Action was completed from June through October 1993 and the site was deleted from the NPL on September 18, 1997.
The site was purchased from Butler County at a tax sale in 1997. The 2007 Five Year Review indicated that Butler County Tax Claim Bureau filed a corrective deed which included a HSCA 512(b) notice stating that there is hazardous waste in place at the Site and a notice of land use restrictions. Additionally, a new access agreement was issued between PPG and the new land owner allow the new owner to conduct operation and maintenance of the existing cap.
The fourth Hranica Five Year Review was signed on April 16, 2012. The Five Year Review indicated that the OU-1, OU-2 and Site-wide remedies were protective of human health and the environment in the short and long term.
