Site Description

The Grand Traverse Overall Supply Company site was a commercial laundering and dry cleaning facility covering one acre in Greilickville, Leelanau County, Michigan. The facility was built in 1953, and dry-cleaning machines were installed in 1968 and 1973. The facility is no longer used for dry cleaning, and the machines were removed in the early 1980s. A dry well was used to collect waste until 1955, but seepage lagoons were constructed in 1955, 1961, and 1968 and collected wastes until 1977 when the facility began discharging waste to the sanitary sewer system. In 1978, Michigan Department of Environmental Quality (MDEQ) discovered that groundwater in the area was contaminated with volatile organic compounds (VOCs) such as trichloroethylene (TCE) and perchloroethylene (PCE). At least 10 wells were found to be contaminated, including a well used by an elementary school adjacent to the facility. The school and other residences used bottled water until new wells in a deeper, confined aquifer were installed. The contaminated wells were abandoned when the new wells were drilled. In the late 1970s, the lagoons on the site were drained and filled with gravel, and contaminated soils around the dry well and barrels of waste sludge were removed. Approximately 1,200 people live within three miles of the site. The nearest residence is 250 feet south of the facility. Cedar Lake, Cedar Lake Outlet, and Grand Traverse Bay are all less than 2,000 feet away from the site. Cedar Lake and Grand Traverse Bay are used for swimming and other recreational activities. 

Site Responsibility

This site is being addressed through federal actions.

Threats and Contaminants

At this time no one is exposed to the groundwater contamination.  Everyone in the area is on a public water supply well.  The building on the GTOS property was torndown by EPA as part of a time critical removal action. The removal program also conducted a vapor intrusion study at the Former Norris Elemetary school next door to the property.  VOC vapors were not detected inside the school but were detected under the foundation of the school building.  A soil vapor extraction (SVE) system was installed under the Norris school building to extract vapors before they could enter the school.  Initially the SVE system was operated and maintainted by MDEQ.  In 2008 the operation of this system was taken over by USEPA and continues to operate to date. 

A groundwater plume had been defined moving off the GTOS property and discharges to the Grand Traverse Bay. 

Cleanup Progress

Initial Cleanup activities:

Since 1978, the site has been the subject of ongoing environmtal inverstgations and regulator enforcement.  In april and may 1978, the Michigan Department of Public Health (MDPH) detected PCE and TCE in the drinking water well located at the Norris School property. Following further investigations by the Michigan Department of Natural Resources (WDNR) currently known as Michigan Department of Environmental Quality (MDEQ), it was determined that the contamination was from the dry cleaning operation (GTOS) located next door to the school.  Under the direction of MDNR, contaminated drinking water wells were replaced by new, deeper wells. In addition, the lagoons assoicated with the dry cleaning operation were drained, and sludge and contaminated soils were removed. In 1988, United States Environmental Protection Agency (EPA) began a study to determine the nature and extent of the groundwater, soil, and surface water contamination assoicated with the Site. The study, completed in 1992, showed that the initial cleanup actions takne by the MDNR had addressed the threats to the public and the environment.

Current Cleanup activities:

In 2001, MDEQ conducted a Phase I investigation as part of a site review. The investigation found previously unidentified groundwater contamination near the GTOS building. Because of this investigation, In 2006, EPA conducted a Site investigation of the GTOS plant area and groundwater and determined that additional contamination remains on-site under the GTOS building.  This contamination is moving off-site in contaminated groundwater going directly to Grand Traverse Bay. In 2007, EPA completed a risk assessment and feasiblity study to address the contaminated groundwater moving into the bay.

In December 2007, the former GTOS building was demolished under the EPA removal program.  In June 2008, approximatley 2,075 tons of soil was excavated and disposed of off-site.

Based on the 2007 FS, site clean-up options where evaluated for the Site and a Record of Decision (ROD) was issued in February 2008 to:  remove any contaminated soils remaining on-site following the removal action, install a pump and treat system to treat the contaminated groundwater plume, and continue operating the vapor extractions system at the former Norris School building.  The EPA is also conducting quarterly sampling to monitor the groundwater and surface water in the area of the site. 

Removal of contaminated soils reamaing on the GTOS property was completed in October 2011.  Approximately 10,300 tons of additional contaminated soil was removed and disposed of off-site. 

The Groundwater pump and treatment system was installed in the fall of 2013.  Operation of the system was started in August of 2013. The EPA continues to monitor the groundwater plume and adjust the pumping system to capture and treat contamined groundwater assoicated with the Site. 

Additionl source are investigation work was completed by EPA in 2012.  It was determined that additonal source areas were present that continue to contribute to the groundwater contamination.  In-situ treatment of these areas will be implemented in the Summer of 2015.  

The Agency continues quarterly monitoring of groundwater, surface water and soil vapor point throughout the plume.


Property Reuse

In June 2014, the GTOS property was purchased along with the former Norris School property for redevelopement by GTRAC, LLC to redevelope the two properties into a community arts and recreation center. 

Potential project benefits identified under the redevelopment of these properties include:

• Redevelopment of a vacant NPL site and shuttered school. Redevelopment efforts will consolidate all parcels that could not be fully utilized on their own.
• Return of all parcels to the tax rolls.
• Increased taxable value.
• Planned approximately $15 million comprehensive development of the Grand Traverse Recreation and Arts Center. Services will include job training, academic services, arts, recreational, child care, and senior activities to the public. Private for-profit entities as well as non-profit groups plan on operating within this development.
• Construction of a new, state of the art, approximately 75,000 square foot, multi-story (3-4 stories) building with an energy goal of the new building designed to be net zero off-grid.
• Creation of approximately 50-100 total full time equivalent (FTE) jobs.

As the cleanup work continues on the GTOS property, the Agency will continue to work with the developer to bring the property back to beneficial use.
