EAST BETHEL DEMOLITION LANDFILL

EPA ID# MND981088180
Last Updated: December, 2012

Site Description

The East Bethel Sanitary Landfill Site is located in north-central Anoka County, East Bethel Township, on 217th Avenue approximately one half mile east of Minnesota Highway 65.  The 60-acre site includes a 27 acre landfill which contains primarily demolition debris with moderate amounts of other wastes, including hazardous wastes.   Abundant wetlands are present near the landfill and Neds Lake is located 1,000 feet south/southeast of the site.   Open fields with interspersed woodlands exist north and east of the site.   A housing development is located to the south/southwest of the site.   Surrounding residences use private wells.  The landfill operated as an unpermitted solid waste disposal facility from 1969 to 1971.  In 1971, the landfill received its first permit and began accepting mixed demolition debris and a small amount of municipal waste.  A limited amount of industrial waste was also accepted at the site, most between 1969 and 1976.   

Site Responsibility

This site was addressed through federal, state, and potentially responsible party (PRP) actions. Currently the site is operated and maintained by the Minnesota Pollution Control Agency (MPCA) under its Closed Landfill Program.

Threats and Contaminants

The primary contaminants of concern affecting groundwater are volatile organic compounds (VOCs) and the heavy metals barium, cadmium, mercury, and lead.   The landfill contains a variety of contaminants. 

Cleanup Progress

In 1981, Anoka County identified elevated levels of volatile organic compounds (VOCs) and other compounds in on-site monitoring wells.  Subsequent investigations by EPA and MPCA confirmed the presence of VOCs in groundwater.  The site was placed on the Minnesota Permanent List of Priorities (PLP) in 1984 and on EPA's National Priorities List (NPL) in 1986. In 1987,  a potentially responsible party and MPCA entered into a Consent Order for performance of a Remedial Investigation and Feasibility Study (RI/FS).  In 1989, at the request of Anoka County, a groundwater extraction well and treatment system was installed as an interim response action.  The RI/FS was completed in 1992.

MPCA signed a cleanup decision for groundwater in 1992, with EPA's concurrence.  The cleanup included installation of a full contaminated groundwater capture system, treatment of the groundwater, and discharge of the treated water to Neds Lake.  This remedy was constructed in 1994 by a responsible party, with oversight by MPCA.  In 1995, the responsible party and the State of Minnesota entered into a Landfill Cleanup Agreement Minnesota's Closed Landfill Program.  Under the agreement, the owners agreed to make improvements to the landfill, including a new landfill cap and passive gas venting.  The agreement also required the owners to transfer ownership of the site to MPCA and record restrictive covenants and easements on certain adjacent parcels.  Construction was completd in 1995 and the site was deleted from the NPL in 1996.  The property was transferred to MPCA in 1999.

Currently the site is operated and maintained by the MPCA.  In 2006-2007, MPCA conducted a major upgrade at the site which included upgrading the groundwater extraction and treatment system, consolidating additional waste, upgrading the landfill cap and installing an active gas control system.   EPA conducted the latest five-year review for the site in 2011 and confirmed that the site remains protective of human health and the environment in the short term.  In order to ensure long-term protection, EPA recommended that MPCA and local governments complete the Closed Landfill Use Plan for the site. 

Property Reuse

The site is located adjacent to the Sandhill Crane Natural Area, an area created by the municipality and MPCA suitable for migrating sandhill cranes to offset encroaching development in the area.  Native grasses have been planted on the landfill to augment the crane environment.
