Hatheway and Patterson Company (HPC) is a former wood preserving facility located in a mixed residential and industrial area in Mansfield, Bristol County, Massachusetts. The HPC property comprises approximately 40 acres and is bordered to the north by County Street and residential properties, to the south and west by forested and wetland areas, and to the east by a welding and masonry supply company. The property is roughly divided in half by the Rumford River, which runs north to south, and by a railroad track right-of-way, which runs east and west. The Hatheway and Patterson Superfund Site was listed on the NPL because releases of dioxins, furans, and phenols from the facility to the Rumford River have impacted fisheries and wetlands, and releases of arsenic, chromium, copper, phenols (including pentachlorophenol (PCP)), and polycyclic aromatic hydrocarbons (PAHs) to ground water were deemed to pose a a potential threat to nearby municipal and private drinking water wells.
Operations at the HPC property included preserving wood sheeting, planking, timber, piling, poles, and other wood products. HPC began wood treating operations at the property in 1953, although it operated at the facility since 1927. Operations between 1927 and 1953 are unknown. Prior to the HPC operations, the Site was utilized for various purposes including rail and truck shipment and storage of various materials, railroad maintenance operations, as well as bulk chemical transfer and processing facilities, although there may have been other uses as well. HPC historically used various methods and materials to treat wood on the property, including PCP in fuel oil, creosote, fluoro-chrome-arsenate-phenol (FCAP) salts, chromated copper-arsenate (CCA), Dricon(tm) (a fire retardant), and other chemicals.
Threats and Contaminants
In 1971, a tar mat approximately 62 feet long and 6 inches wide was discovered by the town of Mansfield and Massachusetts Department of Environmental Protection (MassDEP) personnel. At the end of 1972, a citizen complained of "oily water" and dead water fowl in the Rumford River downstream of the HPC facility. Subsequently, MassDEP and the town of Mansfield requested that HPC contain the seepage. By 1973, HPC developed a contaminated ground water recovery trench located along the east bank of the Rumford River just upstream from its confluence with the Rumford River backwash channel. Oily seepage was again detected in the Rumford River in 1981 by a prospective buyer of the site. In 1987, HPC was issued a Notice of Noncompliance by the MassDEP, which ordered that HPC conduct a soils and hydrology assessment of the site. In 1988, MassDEP issued HPC a Notice of Responsibility, and in 1990, MADEP issued a Request for Short-Term Measure to address the imminent contamination of the Rumford River emanating from the site. In 1992, EPA's RCRA program personnel conducted inspections of the HPC facility and determined that the drip pads were not in compliance. In 1993, HPC filed for bankruptcy and ceased operations in April 1993.
In 1999, the state of Massachusetts, at the recommendation of the Agency for Toxic Substances and Disease Registry, closed the Rumford River from below Glue Factory Pond dam to the Norton Reservoir to all fishing due to dioxin contamination attributed to HPC. Releases of dioxins and phenols also have impacted approximately 1.25 miles of wetland frontage along the Rumford River, and the releases pose a threat to several other wetland areas, fisheries, and habitats used by State designated threatened species downstream of the facility. In addition, over 44,000 people receive drinking water from private and municipal wells within four miles of the HPC facility.
Response Action Status
|Initial Action ||Because wood treating solvents, chemicals, sludges, tanks, sumps, and drums were abandoned by HPC on the property with no electricity or heat, conditions at the site posed a significant threat of hazardous substance releases. Therefore, in December 1993, EPA's Emergency Planning and Response Branch initiated a two year removal action to address problems at the HPC site. Upon initiating the removal action, EPA discovered several process and support buildings that contained large tanks, process vessels, drums, sumps, pits, and various small containers. Outside on the property, EPA discovered three drip pads, treated lumber storage areas, three above ground tanks containing PCP, another tank containing fuel oil, three tanks containing Dricon(tm) in water, and six underground storage tanks. Over 50,000 gallons of waste water was removed by EPA during this action; an undetermined amount of contaminated soil remains at the site. HPC's operations and abandoned materials caused releases of site-related contaminants to soils, ground water, and surface water. |
|Remedial Investigation/Feasibility Study ||Field work for the Remedial Investigation (RI) began in late October 2002 and ended in Fall 2003. The final RI and the Feasibility Study were released in June 2005. |
|Record of Decision ||The Record of Decision was signed on September 30, 2005. The major components of the selected remedy are: (1) Approximately 31,000 cubic yards of soil exceeding cleanup levels will be excavated. (2) The buildings in and near Hatheway & Patterson’s former manufacturing area will be demolished to allow excavation of underlying contaminated soils. Excavated soil will be replaced with clean backfill. (3) Soils containing pentachlorophenol (PCP), semi-volatile organic compounds (SVOCs), and arsenic will be excavated, tested for leachability and, if they fail, stabilization/solidification agent(s) will be utilized. The stabilized/solidified soils will then be consolidated on-site under a low-permeability cover. (4) Soils containing dioxin and oily material (LNAPL) will be disposed of off-site at a licensed facility. (5) Institutional controls will prohibit the use of Site groundwater and restrict land uses in a manner that ensures the protectiveness of the remedy as described in this ROD, and ensures the integrity of the on-site low-permeability cover and other remedial components. Risks from soil exposures within the area of the existing railroad right of way will be evaluated during design and appropriate action such as deed restrictions or other legal and administrative measures will be implemented if necessary. (6) Long term monitoring of groundwater, surface water, fish tissue and sediment. (6) Five-year reviews, and operation and maintenance of remedial components, including the low permeability cover. |
EPA conducted a preliminary environmental investigation in the Fall of 2001 and issued a Final Data Report on June 4, 2002. The preliminary environmental investigation focused on sampling existing ground water monitoring wells at the site and collecting water and sediment samples from the Rumford River. The Final Data Report summarizes all historical soil data collected at the site as well as data collected during the preliminary environmental investigation. Based on the information presented in the Final Data Report, EPA was able to identify where additional information is needed to complete a Remedial Investigation. A Remedial Investigation of the Hatheway & Patterson site was completed in the Spring of 2005. After a public comment period, EPA selected a remedy, outlined in the Record of Decision dated September 30, 2005. EPA demolished most of the former Hatheway & Patterson production buildings during the summer of 2006. The Remedial Design was completed in September 2008. Remedial Action work began in 2009 and was completed in September 2010.
Funding for the remediation construction at the Hatheway and Patterson Superfund Site was provided via the American Recovery and Reinvestment Act of 2009 (ARRA), with a 10% cost share provided by the Massachusetts Department of Environmental Protection. The work was managed for US EPA by the US Army Corps of Engineers. Work began at the Site during the late summer of 2009 and was completed in the fall of 2010. Approximately 43,500 tons of contaminated soil were excavated and shipped off-site to a hazardous waste landfill. The Corps of Engineers selected Sevenson Environmental Services, Inc. to perform the cleanup work at the Site.
Hazardous materials within the approximately 2 acres of the Site in Foxborough, MA were consolidated in place under an asphalt cover. The Town of Foxboro, MA is utilizing the resulting parking lot to service the nearby MBTA commuter rail station. The commuter rail provides service to Providence and Boston. The Town of Foxborough made necessary improvements, including lighting and striping of parking spaces before the lot was opened for public use.
The remaining 36 acres of the Site are within Mansfield, MA. The Southeast, Southwest, and Northeast Quadrants of the Site in Mansfield, MA were seeded after any necessary fill was placed. The Northwestern Quadrant in Mansfield was restored with dense sub-grade material. The Town of Mansfield, MA intends to reuse its portion of the site for either open space or commercial purposes.
Current Site Status
In September 2014 EPA completed the first Five-Year Review of the Site. This five-year review is a requirement under Section 121 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which requires EPA to review Superfund sites every five (5) years after the completion of a remedial action where contaminants remain on site until the contaminant levels reach concentrations at the site that will allow for unlimited use and unrestricted exposure. The intent of this five year review is to evaluate the implementation and performance of the remedy in order to determine if the remedy is or will be protective of human health and the environment. The five-year reviews involve a review of the results from monitoring activities, operation and maintenance reports and other relevant site data that may be collected by a variety of means, including document review, interviews, site inspections, and possibly supplemental sampling to obtain additional data.
The remedy at the Site currently protects human health and the environment because remediation of the soil (soil removal and on-site consolidation) has been completed to cleanup levels that are considered protective for the anticipated future use of the property, and there is no current use of on-site groundwater which is classified as non-potable. However, in order for the remedy to be protective in the long-term, institutional controls need to be created and recorded to restrict inappropriate land uses (including use of groundwater) and protect the consolidation area cover. Operation and maintenance activities have been initiated and will ensure that the consolidation area and associated components of the remedy (e.g., groundwater monitoring wells) remain in good condition. In addition, monitoring of groundwater will continue to assess the protectiveness of the remedy.
