Remediated Strasburg Landfill Superfund Site Removed from National Priorities List
U.S. EPA has completed the clean up of the Strasburg Landfill Site in Newlin Township, Pennsylvania and removed it from National Priorities List (a.k.a. "Superfund").
This month the U.S. Environmental Protection Agency (EPA) officially removed the 302-acre Strasburg Landfill Site in Newlin Township, Pennsylvania from the National Priorities List (NPL), also known as the "Superfund." EPA deletes sites from the NPL, with state concurrence, when all site cleanup goals have been met, no further response is necessary other than operation and maintenance and five-year reviews, and the remedy is determined to be protective in the long-term.
The Strasburg Landfill Site was once heavily contaminated with hazardous chemicals due to past disposal practices on the property. The landfill accepted industrial waste, including polyvinyl chloride (PVC) wastes and heavy metal sludge from 1979 until 1980, when the state required the closure of the landfill. The Site was added to the Superfund NPL in 1989. In 2012, EPA updated the site’s remedy to include institutional controls to prevent exposure to waste and contaminated groundwater, as well as to preserve the integrity of the remedy. After an extensive cleanup, ongoing operations and maintenance, and regular sampling activities, EPA has confirmed that public health and the environment are protected.
The site’s long-term remedy included construction of a multi-layer cap and subsurface leachate collection system, installation of treatment units at affected residences, and construction of a fence around the site. It was also determined that “No Action” was needed for groundwater because contamination was not migrating from beneath the landfill cap. Construction of the remedy was completed in 1999. Groundwater monitoring, operation and maintenance of the cap and the leachate collection and treatment system remain ongoing.
“EPA is intently focused on making substantial and meaningful progress cleaning up Superfund Sites,” said EPA Regional Administrator Cosmo Servidio. “Delisting the Strasburg Landfill Site from the Superfund list is an important milestone that marks the completion of many years of cleanup work and collaboration across many levels of government and private parties that will allow for future planning for the site.”
The public had an opportunity to comment on this proposed deletion during a 30-day public comment period from July 3 until August 2 of this year. One comment was received and is addressed by EPA in the responsiveness summary that accompanies the Notice of Deletion in the Federal Register.
EPA has conducted several Five-Year Reviews of the site, which are to ensure that the remedies put in place continue to protect public health and the environment, and function as intended. The site's next Five-Year Review is scheduled for 2020.
