Rolling Knolls Landfill

Rolling Knolls Landfill Site History

Rolling Knolls landfill is an approximately 200-acre site located in the Green Village section of Chatham Township which was used as an unlined landfill from the early 1930s through 1968.  During its use, it received municipal solid waste, construction and demolition debris.  According to the Chatham Board of Health, waste included tree stumps, scrap metal, tires, household refuse, residential septage waste and industrial waste.  Herbicides and pesticides were used to control weeds, insects and rodents.  Oil was applied on facility roadways to control dust.  Most of the site is privately held, however, approximately 30 acres are owned by U.S. Fish and Wildlife Service as part of the Great Swamp National Wildlife Refuge.
Landfill operations contaminated soil, sediment, surface water and groundwater.  Contaminants consist of elevated levels of arsenic, lead, mercury, polycyclic aromatic hydrocarbons (PAHs), pesticides, phthalates, polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), freon compounds, dioxin and furans.

EPA Determination: Superfund

After many years of investigation, EPA determined that the site was a threat to people and the environment and the site was placed on the Environmental Protection Agency National Priorities List for cleanup in 2003.  What exactly does this mean?

In 1980, after toxic waste dumps such as Love Canal received national attention and the public learned about the risks to human health and the environment caused by contamination, Congress established the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), more commonly known as Superfund.  The Superfund law allows EPA to clean up contaminated sites, including requiring responsible parties to perform the cleanup or pay for it.

According to EPA, Superfund goals are:

• Protect human health and the environment by cleaning up polluted sites
• Make responsible parties pay for cleanup work
• Involve communities in the Superfund process, and
• Return Superfund sites to productive use

After having listed Rolling Knolls as a Superfund site, EPA identified potentially responsible parties (PRPs) who then conducted a lengthy remedial investigation through soil and water sampling and a risk assessment.  The next step in the process is an analysis of potential cleanup alternatives, called a Feasibility Study and identification of a preferred proposed cleanup plan.

February 2019:  Currently awaiting feasibility study to be released. The feasibility study will be followed by a 30 day public comment period.
September 2018: The Rolling Knolls Feasibility Study and proposed cleanup plan was due to be released by the EPA in September 2018.
June 2018: At a Public Information Session held by EPA in June, the following potential cleanup options were listed:

Soil Alternatives:

• No action
• Site controls (such as institutional controls, fencing, signage)
• Site controls, capping of selected areas to reduce overall risk and remediation of additional areas of concern
• Site controls, excavation and offsite disposal of selected area to reduce overall risk and remediation of additional areas of concern
• Site controls and capping of all landfill material

Groundwater alternatives:

• No action
• Source control and monitoring
• Source control and monitoring, with a contingent remedy

The proposed cleanup plan will summarize preliminary conclusions and delineate why the selected option appears most favorable.
The proposed plan must be protective of human health and the environment and must comply with the law.  Additionally, seven other factors are weighed in determining the preferred cleanup plan.  They are:

• Long term effectiveness
• Reduction of toxicity
• Short term effectiveness
• Implementability
• Cost
• State acceptance
• Community acceptance

US Fish and Wildlife Field Investigation:

Executive Summary: This Uniform Federal Policy Quality Assurance Project Plan (UFP-QAPP) is Part 1 of the Work Plan for the Data Gap Site Characterization (DGSC) at the Great Swamp National Wildlife Refuge (Refuge) associated with landfill contamination and debris from the Rolling Knolls Landfill Superfund Site located in Morris County, New Jersey (the Site). The purpose of the UFP-QAPP is to be the comprehensive site-specific planning and guidance document to govern the field sampling, field analysis, and environmental laboratory analysis for the work contracted under Task Order (TO) : 140F0520F0195 for the United States Fish and Wildlife Service (FWS). This document shall be utilized by the field sampling team and the laboratory analytical team to ensure this effort meets the specified project quality objectives (PQOs) for the TO.

This project is contracted by the FWS, Division of Contracting and General Services under General Services Administration Contract GS10F026BA, TO 140F0520F0195. The Health and Safety Plan (HASP) is Part 2 of the Work Plan and will be submitted in a separate document. The objectives of DGSC are to evaluate the threat to the Refuge from chemicals that have been released into the environment from Rolling Knolls Landfill activities, define the extent of contamination on the Refuge in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and regulations of the New Jersey Department of Environmental Protection (NJDEP).
