Bountiful/Woods Cross 5th S. PCE Plume
Bountiful/Woods Cross 5th S. PCE PlumeThe 450-acre Bountiful/Woods Cross 5th South PCE Plume Superfund site is in Bountiful, Utah. It includes two properties – the 50-acre Hatchco property and the 400-acre Bountiful Family Cleaners (BFC) property. From 1936 to 1996, several businesses operated on site, including a petroleum facility, a dry cleaner and a trucking business. Over time, spills and leaks from operations and holding tanks contaminated soil and groundwater. The main contaminant at the BFC property was tetrachloroethylene (PCE) and at the Hatchco property was trichloroethylene (TCE). PCE is a solvent used by dry cleaners in the cleaning process and TCE is used as a solvent to remove grease from metal parts. EPA added the site to the National Priorities List (NPL) in 2001. Cleanup included use of barriers, a water treatment system and long-term monitoring. Construction of the water treatment system finished in 2011. The site is currently in reuse. The Utah Transit Authority paved part of the Hatchco property to serve as a vehicle parking lot for the Utah Commuter Rail System. BFC remains active at the site and leases parts of its property to other commercial businesses. There are continued industrial, agricultural and residential land uses in the area impacted by groundwater contamination. Interstate 15 and rail lines also cross the site.

Davenport and Flagstaff Smelters
The Davenport and Flagstaff Smelters Superfund site is located near Sandy, Utah, about 15 miles from Salt Lake City. The site is in a residential and commercial area at the mouth of Little Cottonwood Canyon. The Davenport, McKay and Flagstaff smelters operated throughout the 1800s. In 1991, the discovery of ladle casts in Little Cottonwood Creek near the Flagstaff Smelter prompted a study of smelter sites in the Salt Lake Valley. Investigations by EPA in 1992 and by the Utah Department of Environmental Quality (UDEQ) in 1994 found high levels of arsenic and lead in soil at both smelter locations. EPA added the site to the National Priorities List (NPL) in 2003. In 2006, under an agreement and with oversight by EPA and UDEQ, Little Cottonwood Canyon Partners, LLC cleaned up part of the site for residential redevelopment. In 2011, UDEQ led the cleanup of a commercial area where a restaurant was located and undeveloped land designated as a watershed protection zone. All of the cleanups included the removal and proper disposal of contaminated soils. The site is in continued use. Land uses include a residential area, a restaurant and the watershed protection zone. In 2018, EPA removed the site from the NPL.

Empire Canyon
The Empire Canyon site is located in the headwaters of Empire Canyon, south of Park City, Utah, about 25 miles from Salt Lake City. Beginning in the late 1800s, ore mining and processing facilities operated on site, contaminating a 36-acre area with mine wastes containing arsenic, lead and zinc. In 2000, a local watershed group found contaminated soils and surface water. In 2003, the site owner, United Park City Mines Company (UPCMC), agreed to clean up the site. Cleanup included removing contaminated soil, covering areas with clean soil and rerouting surface water. In 2006, EPA and the U.S. Department of Justice negotiated a Prospective Lessee Agreement (PLA) with UPCMC’s new lessee, DV Luxury Resort, LLC (DVLR). The PLA provided liability relief for DVLR in exchange for DVLR's help with cleanup. Since 2006, DVLR has constructed the Montage Deer Valley Resort & Spa. The luxury hotel features a spa, restaurants, event spaces, a condominium complex, and ski-in, ski-out access to Deer Valley Resort. With help from EPA, DVLR incorporated sustainable features into all phases of the resort’s creation, from design to construction. The resort opened in 2010. It participates in the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program. DVLR used local building materials during construction and added a 2,800-acre conservation easement around the resort. The resort uses wind-generated power from Utah Blue Sky, has a comprehensive recycling system and provides local jobs.

Eureka Mills
Eureka MillsThe Eureka Mills Superfund site is located about 80 miles from Salt Lake City, Utah. This historic mining area includes Eureka, a city of 800 residents, and some nearby areas. Mining activities started in 1870, after the discovery of silver, lead and minerals. Mining ended in 1958. EPA started cleanup actions in 2000 and 2001, after sampling confirmed high levels of contamination in the area. In 2002, EPA added the site to the National Priorities List (NPL). Between 2001 and 2010, EPA cleaned up more than 700 properties in Eureka. Other actions included waste capping, contaminated soil disposal, land use controls and public health actions. EPA completed cleanup activities a year ahead of schedule. Since site boundaries included the entire city, many properties in Eureka were already in residential and commercial use before the Superfund cleanup. EPA’s cleanup planning enabled continued commercial and residential use of the site during cleanup activities while also ensuring a safe living and working environment. The site also includes public services such as schools and government offices. In 2018, EPA deleted the site from the NPL.

Five Points PCE Plume
The Five Points PCE Plume Superfund site is in the Salt Lake Valley in Davis County, Utah. An area of contaminated groundwater begins in the town of Bountiful and extends for about one mile under Woods Cross City and North Salt Lake City. Woods Cross City found tetrachloroethylene (PCE) contamination in a drinking water supply well in 1988. Investigations found that the most likely source of the PCE was Your Valet Cleaners, a dry cleaner facility in Bountiful. The business used PCE for dry cleaning from 1964 to 2002, when they switched to a silicone dry cleaning solution. EPA added the site to the National Priorities List (NPL) in 2007. Utah Department of Environmental Quality is leading ongoing investigation and cleanup efforts. EPA selected a remedy for the site in 2016. Cleanup includes groundwater pumping and treatment, as needed, and land and groundwater use restrictions to prevent contact with contamination. The site is located in an established urban area with continued residential and commercial uses.

Intermountain Waste Oil Refinery
The 2-acre Intermountain Waste Oil Refinery Superfund site is located in Bountiful, Utah. Beginning in 1957, operators used the area for waste oil handling, refining, blending and shipping. The Davis County Health Department and the Utah Department of Environmental Quality (UDEQ) cited the business several times because nearby residents complained of odors and health issues. After the company closed in 1993, UDEQ investigated the extent of contamination in soil and groundwater. Human health risks led EPA to add the site to the National Priorities List (NPL) in 2000. EPA removed chemical containers, storage barrels, scrap equipment, debris and underground tanks. In 2006, Bountiful Irrigation purchased the site property. The irrigation supply and design business built an office and garage, and fenced the property. The office uses a vapor mitigation system, which EPA required because contaminated groundwater extends below parts of the building. Groundwater monitoring at the site is ongoing.

International Smelting and Refining
International Smelting and RefiningThe 1,200-acre International Smelting and Refining Superfund site is located northeast of Tooele, Utah. The site is near the mouth of Pine Canyon, which drains into Pine Creek. Between 1910 and 1972, the Atlantic Richfield Company (now known as ARCO) operated copper smelters that also recovered lead and zinc. Smelter operations produced about 650,000 tons of smelter waste and dust. Wind spread contaminants and dust from tailings piles over large areas of surface soils. In response to elevated blood-lead levels of area residents, EPA placed the site on the National Priorities List (NPL) in 2000. With EPA oversight, ARCO conducted targeted cleanups at the smelter facility, the Tooele Valley Railroad and the Pine Canyon community. Immediate cleanup actions removed contaminated soils from some residential properties closest to the former smelter area. Cleanup along the former Tooele Valley Railroad, the Pine Canyon Conservation Area and city-owned Oquirrh Hills Golf Course included removal of contaminated soil, backfilling with clean soil, capping of areas where contaminated soil was not removed and revegetation using native plants. Actions to ensure the remedy’s long-term stability included fencing, stormwater control modification and repair, and land use controls. EPA took the site off the NPL in 2011. As a result of Superfund cleanup, the site remains in use. The Utah Division of Wildlife Resources manages the former smelter area as the Pine Canyon Conservation Area. This area provides the public with recreation opportunities, including hiking, horseback riding, wildlife observation and hunting. Part of the Tooele Valley Railroad cleanup area included the city-owned Oquirrh Hills Golf Course, which remains in operation today. The former Toole Valley rail line is now a biking and walking trail. Cleanup has also allowed for continued use of residential properties. A gun club with a trapshooting club also operates on site.

Jacobs Smelter
Jacobs SmelterThe Jacobs Smelter Superfund site includes the town of Stockton, Utah, and surrounding areas. Reports documented at least nine smelters with milling operations at the site during the 1800s. The site’s name comes from one of the largest smelting operations in the area. These smelter operations caused soil contamination. EPA discovered contamination at the site in 1995. In 1999, EPA began cleaning up the former Jacobs Smelter property and 29 heavily-contaminated residential properties. EPA added the site to the National Priorities List (NPL) in 2000. EPA divided the site into six operable units (OUs). Cleanups have been completed in the town of Stockton (OU1), an area owned by Union Pacific Railroad (OU3), and an area owned by Rio Tinto Kennecott (OU4). EPA deleted OU1 and OU3 from the NPL in 2001 and 2005, respectively. Cleanup is continuing at OU2. EPA is assessing whether cleanup at OU5 is complete. A remedial investigation and feasibility study are needed at OU6 before EPA can select a cleanup plan. OU4 will be proposed for partial deletion in the near future, and as OU2, OU5 and OU6 reach cleanup goals, EPA will remove them from the NPL. Continued uses at the site include the town of Stockton, an active rail line, and residential, recreational and commercial areas.

Kennecott (North Zone)
Kennecott (North Zone)The Kennecott (North Zone) site is located in an industrial area west of Salt Lake City, Utah. Starting in 1906, the Kennecott Utah Copper Company (Kennecott) processed metals, including copper and lead, in the area. Production wastes contaminated area soil and groundwater. This contamination forced the closure of drinking water wells in the area. EPA proposed listing the site on the National Priorities List (NPL) in January 1994. In 1995, EPA agreed that Kennecott would continue the cleanup and EPA would postpone the site’s listing on the NPL. Kennecott’s cleanup included removal and disposal of contaminated soils, sediments and sludges. Kennecott is currently cleaning up groundwater and has connected residences and businesses to public water supply lines. Today, Kennecott maintains active mining operations on part of the site. Interstate 80, state highways and rail lines pass through the site. The entire community of Magna is considered a part of the site, including continued residential, commercial and public service uses. Part of the site bordering the Great Salt Lake provides recreation and research opportunities. Kennecott purchased land along the south shore of the Great Salt Lake and turned a once-degraded wetland into a shorebird and waterfowl reserve. Birding groups, schools and university research teams observe and study wildlife in the wetland, which has become a haven for birds and an important education and scientific resource.

Kennecott (South Zone)
Kennecott (South Zone)The Kennecott (South Zone) site is located southwest of Salt Lake City, Utah. It covers about 37 square miles. Mining activities at the site began in the 1860s and continue today. Starting in 1906, the Kennecott Utah Copper Company (Kennecott) also used the area to process metals. Wastes produced by these activities contaminated soil, groundwater, surface water and sediment. This contamination led to the closure of drinking water wells in the area. EPA proposed listing the site on the National Priorities List (NPL) in 1994. In 1999, Kennecott removed more than 25 million tons of contamination. EPA withdrew the site’s NPL listing proposal in 2008, after signing a cleanup agreement with Kennecott. Cleanup included removal of contaminated soils, sediments and sludges. Groundwater treatment is ongoing. Cleanup has also resulted in significant ecological benefits, including the creation of about 1,000 acres of wildlife habitat and open space. The Kennecott Land Company redeveloped 4,126 acres of the site into the Daybreak community. The development is a model of environmentally and socially responsible growth. All 13,600 homes and 9.1 million square feet of commercial building space meet EPA Energy Star efficiency guidelines. The community also features 1,250 acres of parks, a recreational lake, pedestrian-friendly town centers, shops, restaurants, grocery stores, churches, schools and mass transit. Kennecott’s owner, Rio Tinto, opened a corporate office in the Daybreak community. The office has been certified by the U.S. Green Building Council’s Leadership in Energy and Environmental Design program. Ongoing development in the Daybreak community includes public transportation corridors, additional homes and businesses, as well as light industry and agriculture.

Midvale Slag
Midvale SlagThe 446-acre Midvale Slag Superfund site is in Midvale City, Utah. From 1871 to 1958, five smelters processed lead and copper ore at the site. Site operations resulted in toxic levels of heavy metals in area soils and groundwater. EPA added the site to the National Priorities List (NPL) in 1991. EPA worked with state agencies, the city of Midvale (the City), local citizens and the site owner to link the cleanup with revitalization and redevelopment goals. Midvale became the first community in EPA Region 8 selected as a Superfund Redevelopment pilot project. This led to the groundbreaking creation of the Bingham Junction Reuse Assessment and Master Plan in 2000. Today, the site is home to Bingham Junction, a thriving mixed-use development supporting thousands of jobs. Builders have completed extensive residential development at the site. New buildings on site include single-family homes, townhomes, condominiums, apartments and assisted living. The site is also home to office buildings, a supermarket and other stores. FL Smidth, an international engineering company, operates office and laboratory buildings on site. Its buildings achieved the U.S. Green Building Council’s Leadership in Energy and Environmental Design program’s Gold and Silver certifications. CHG Healthcare Services developed 283,000 square feet of space. Overstock.com developed a 231,000-square-foot office building, a 50,000-square-foot daycare and fitness studio, parking structure, and greenhouse to provide fresh fruits and vegetables for the on-site café. In total, developers plan to build up to 2 million square feet of commercial office and retail space on site. EPA also addressed soil contamination in an unmarked pioneer cemetery on the site. Sections of Bingham Junction’s Riverwalk Park have opened, providing improved community access to the Jordan River. A Utah Transit Authority light rail station opened on site in summer 2011. In 2015, EPA took the site off the NPL; all required cleanup activity is complete. EPA Region 8 also recognized the City with an Excellence in Site Reuse Award for their efforts to support reuse and redevelopment at the site. The Midvale Redevelopment Agency reopened Bingham Junction Park in 2016 with a new softball field, basketball court, play structure and sledding hill. Twenty-plus years of collaboration and dedication at the local, state and federal level have transformed this once-contaminated land into a vibrant community resource.

Sharon Steel Corp. (Midvale Tailings)
Sharon Steel Corp. (Midvale Tailings)The 470-acre Sharon Steel Corp. (Midvale Tailings) Superfund site is in Midvale, Utah. A smelting and ore-milling facility produced lead, copper, zinc and other metals on site from 1906 to 1971. Site investigations found contaminated groundwater and soil. EPA added the site to the National Priorities List (NPL) in 1990. EPA and the state of Utah’s cleanup activities included fence installation, riverbank stabilization, dust control, building removal, waste capping, groundwater monitoring, and removal of contaminated soil with clean soil backfilling. Soil cleanup allowed for the continued residential and commercial use of several impacted properties. Cleanup finished in 1999. EPA took the site off the NPL in 2004. The same year, EPA issued a Ready for Reuse Determination stating that the site is ready for residential and mixed reuse. The Jordan River Parkway Trail runs along the site’s western edge, supporting a variety of non-motorized recreational uses. In 2010, EPA developed a review document to help clarify what types of uses would be appropriate in the capped portion of the site. An extension of Bingham Junction Boulevard crosses the vacant portion of the site. In 2017, KC Gardner, the developer of the adjacent Midvale Slag Superfund site, purchased the undeveloped area of the site. The developer is planning a residential and commercial redevelopment project for the site called Jordan Bluffs. With EPA’s mission to protect human health and the environment in mind, EPA established the Superfund Task Force in May 2017 to provide recommendations for improving and expediting site cleanups and promoting redevelopment. Based on the Superfund Task Force recommendations, EPA identified the site as a Redevelopment Opportunity site – a site with the greatest expected redevelopment potential. In October 2018, the city of Midvale held a very successful redevelopment groundbreaking event for the Jordan Bluffs subdivision, a 265-acre, master-planned, mixed-use development that will include up to 1,000,000 square feet of office, data center, retail/hospitality, and residential components around a linear park.

Utah Power & Light/American Barrel Co.
Utah Power & Light/American Barrel Co.The 2-acre Utah Power & Light/American Barrel Co. Superfund site is located in Salt Lake City, Utah. Site operators conducted barrel storage, wood-treating and coal gasification operations on site from 1870 to 1987. These operations produced byproducts such as tar, sludge, ash and liquid wastes. Combined with chemicals from leaking barrels, the byproducts contaminated soil and groundwater. EPA placed the site on the National Priorities List (NPL) in 1989. Utah Power & Light, the responsible party, removed 50,000 barrels, removed and disposed of contaminated soil off site, and built a soil vapor and groundwater extraction system. Remedy construction finished in 1996. The soil vapor and groundwater extraction system continues to operate. Groundwater monitoring is ongoing. Groundwater and land use restrictions are in place at the site. Several redevelopment activities have taken place at the site and nearby. In 2007, Union Pacific Railroad realigned tracks that ran across the site to increase the efficiency of its rail service and address rail safety concerns.
