Quincy Smelter: From Stamp Sands to National Historic Park THE QUINCY SMELTER SUPERFUND SITE IN HOUGHTON COUNTY, MICHIGAN www.epa.gov Introduction Built in 1898, the Quincy Smelting Works is part of the Quincy Mining Company National Historic Landmark and the only copper smelter still standing in the Great Lakes region. Located in Franklin Township, Michigan, the smelter ceased production in the 1971. However, its historic buildings and structures remain intact, making it the best preserved copper smelter in the country. The smelter facilities are located along Portage Lake on the Keweenaw Peninsula. In 1992, Congress recognized the region’s copper mining and production heritage, creating Keweenaw National Historical Park and including the smelter as part of it. Today, the National Park Service and the Keweenaw National Historical Park Advisory Commission manage and coordinate historic preservation and interpretative initiatives, contributing to a growing heritage tourism industry across the Keweenaw Peninsula. Quincy Smelter was also part of the larger Torch Lake Superfund site. Since the late 1990s, EPA, the National Park Service, the Keweenaw National Historical Park Advisory Commission, Michigan Department of Environmental Quality (MDEQ), Franklin Township and local partners have worked in collaboration to address the site’s environmental contamination The site is located in the Upper Peninsula region of Michigan, between Lake Superior and the Keweenaw Bay. The town of Hancock is located while preserving the area’s remarkable historical resources. west of the site. Efforts by EPA’s Superfund Redevelopment Initiative and of Keweenaw National Historic Park and as a gateway to Isle community leaders led to the creation of a shared vision and reuse Royale National Park. plan for the site and spurred inter-agency collaboration resulting in its remediation. Following cleanup, federal, state and local This case study explores the strategies and collaborative partners identified an ownership transfer strategy, coordinated relationships that led to the successful cleanup and reuse of the the Quincy Smelter site’s deletion from the Superfund program’s Quincy Smelter site. The following pages trace the evolution of National Priorities List (NPL), and assisted with transfer of cleanup and reuse efforts, highlighting local planning efforts, site ownership to the Advisory Commission. The Advisory coordination with regulatory agencies, and ongoing cleanup Commission has since worked to further stabilize the site’s and reuse activities through 2016.

Quincy Smelter from Portage Lake (2016) U.S. Environmental Protection Agency 1 Superfund Redevelopment Initiative Site History, Contamination and Remediation Site Highlight: Torch Lake Superfund Site From 1898 to 1971, the Quincy Mining Company’s The 2,700-acre Torch Lake Superfund site is located on smelter operations used heat and chemical processes Michigan’s Keweenaw Peninsula. The site includes lakes, to refine copper ore mined from the nearby Quincy ponds, waterways and tailing piles. From the 1890s until Mine. The facility included reverberatory furnaces, 1971, copper mining activities included the deposition of mine wastes into the surrounding surface water and soil, resulting in a cupola furnace, machine and cooper shops, boiler groundwater, surface water and soil contamination. houses, blacksmith shop and several additional support buildings. After EPA placed Quincy Smelter as an Area Copper mining and processing activities in the area from the of Concern (AOC) within the Torch Lake Superfund 1890s until 1971 produced mill tailings that contaminated site on the NPL in 1986, EPA issued a Record of the lake sediments and shoreline. About 200 million tons of Decision (ROD) determining that no further action copper mill stamp sands were dumped into Torch Lake itself, was required at the time to address contamination at filling about 20 percent of the lake’s volume. Quincy Smelter. In 2005, EPA installed storm culverts and shore stabilization materials. However, as part of the five-year review process in 2008, EPA found that the stamp sand tailings that the company had built the facility on had begun to erode into Portage Lake. Quincy Smelter (OU3) This stamp sand waste posed a threat to the environment and led EPA to conduct a comprehensive remedial investigation. EPA formally updated the site’s remedy with a ROD Amendment in 2009. Cleanup actions started in 2009 and finished in September 2011. Cleanup included: • A soil cover over exposed tailings and cover seeding with native plants. • Enhanced stormwater management and site drainage infrastructure. • Fencing to temporarily restrict site access until the site is ready for reuse. • Erosion controls along the Portage Lake shoreline. • Institutional controls in the form of restrictive covenants to limit residential use, and to protect and maintain the cover. • Long-term operation and maintenance activities to ensure the remedy’s protectiveness. Prior to the ROD amendment, EPA conducted regular removal assessments, where EPA found asbestos in site structures, which led to an asbestos removal in 2008. The site’s cleanup also required shoreline stabilization efforts along Portage Lake to protect the stamp sands and vegetative cover from further erosion. Congress appropriated funds for shoreline stabilization, which created a stable shoreline and potential for re-activating a docking facility at the site. Throughout these activities, EPA and MDEQ staff members met regularly with community stakeholders to share information and updates and to incorporate a vision and future land use plan into the Superfund process. The selected remedy enabled the property to be reused for recreation and historic preservation uses, which EPA identified as the site’s reasonably anticipated future land uses. With the site’s long-term remedy in place, EPA took Quincy Smelter off the NPL in 2013. 2 Timeline of Events Date Action 1898-1971 Quincy Smelting Works in active operation 1984 EPA starts investigations for the Torch Lake site June 1986 EPA places the Torch Lake site on the NPL; Quincy Smelter is part of the site 1992 Congress establishes Keweenaw National Historical Park September EPA issues Torch Lake Operable Unit 3 ROD, which includes Quincy Smelter 1992 2005 EPA completes time-critical action for the installation of storm culverts and shoreline/bank stabilization March 2008 EPA’s five-year review identifies erosion of stamp sands into Portage Lake May 2008 First phase of reuse planning process underway 2008 EPA completes time-critical action to complete an asbestos abatement for Quincy Smelter buildings and 2008 deteriorated smokestack removed November EPA releases reuse assessment for Quincy Smelter 2008 December Second phase of reuse planning process starts 2008 2009 EPA completes remedial action to cover and stabilize stamp sand tailings July 2009 Reuse planning community open house and charrette takes place July 2009 EPA updates site remedy, issues ROD Amendment January EPA releases reuse framework for Quincy Smelter 2010 Quincy Smelter Steering Committee completes redevelopment proposal, building on earlier reuse planning 2011 efforts September Remedial action for Quincy Smelter AOC finishes 2011 October EPA releases reuse concept plan for Quincy Smelter 2011 July 2013 EPA issues “reasonable steps” letter to Keweenaw National Historical Park Advisory Commission October EPA takes Quincy Smelter site off the NPL 2013 November NPL deletion ceremony takes place at the site 2013 Keweenaw National Historical Park Advisory Commission acquires smelter site property, conducts additional August 2014 cleanup, and EPA conducts emergency response to remove mercury contamination Ongoing activities include planned ownership transfer to the National Park Service and additional facility 2017+ improvements for historical park interpretation 3 1986 - 2006Keweenaw HeritageKeweenaw Sites National Historic Park Sites Keweenaw County Historical Society Passenger Ferry to Eagle Harbor Lighthouse & Museum Isle Royale Adventure Mining Company Fort Wilkins Historic State Park Identifying Challenges, Pursuing a Unique 26 A.E.
