What's New?

Updated November 2011

EPA conducted the third five-year review of the remedy implemented at the Utah Power & Light/American Barrel Co. Superfund Site, located in Salt Lake City, Utah from December 2010 through May 2011. Overall, groundwater monitoring data suggest that the underlying organic contaminated plume has remained within the boundaries of the site. Present contaminant levels in groundwater are consistent with expectations at time of the 1993 Record of Decision. Stringent institutional controls are in place to restrict use of the contaminated groundwater and residents/businesses in the area are connected to the municipal water system.

Site Description

The 2.2-acre Utah Power & Light/American Barrel Co. site was used as a barrel storage yard. Empty barrels on the site at one time contained residues of various volatile organic compounds (VOCs), degreasers and solvents.

Current operation and maintenance (O&M) activities include operation of a soil vapor and groundwater extraction system and groundwater monitoring. A five-year review was completed in September 2006. The results of the review indicate that the remedy is operating and functioning as designed and is expected to be protective of human health and the environment. Redevelopment of the site is planned over the next two years.

The site was proposed for the Superfund National Priorities List (NPL) in May 1989 and finalized on the list in October 1989.

Site Risk

Sub-surface soils on the site contained polycyclic aromatic hydrocarbons (PAHs), VOCs and cyanide from wood-treatment and coal-gasification operations. Surface soils also contained lead from metalliferous slag fill brought to the site, pesticide residues from the barrels, and PAHs from coal debris. Groundwater contained VOCs, including benzene, styrene, toluene, xylene and cyanide. Potential health risks existed for anyone exposed to contaminated soil and/or groundwater over a long period of time.

Media Affected Contaminants Source of Contamination
soil, groundwater polycyclic aromatic hydrocarbons, benzene, styrene, toluene, xylene, lead, pesticides wood-treatment and coal-gasification operations, barrel storage

Cleanup Progress

Cleanup Completed

The following cleanup activities were completed by the potentially responsible party (PRP)—Utah Power & Light:

  • Removal of 50,000 empty barrels to a federally approved facility in 1988.
  • Excavation and removal of 20,000 tons of soil off-site for processing into asphalt.
  • Removal of 1,388 tons of miscellaneous non-hazardous debris to a commercial landfill.
  • Construction of a soil vapor and groundwater extraction system in 1996.

Site cleanup was completed in 1996.

Community Involvement

Community involvement plays an important role in the Superfund process. EPA uses a number of different tools and resources to promote effective, on-going, meaningful community involvement. The goals of the Superfund community involvement program are to:

  • Keep communities affected by sites informed throughout the cleanup process.
  • Provide opportunities for communities to comment and offer their input about site cleanup plans.
  • Facilitate the resolution of community issues tied to a site.

Notices were placed in local newspapers indicating that the 2011 five-year review was in progress.

EPA places a high priority on land reuse as part of its Superfund response program mission. The agency tries to select cleanup options that encourage and support future use of a site. EPA uses two fundamental methods to facilitate reuse of Superfund sites:

  • Exploring future uses before the cleanup remedy is implemented, an approach that gives the Agency the best chance of designing cleanup remedies to support the likely future use of a site.
  • Working with landowners and communities to remove barriers not considered necessary for the protection of human health or the environment at those sites where remedies are already in place.

One option for reuse is the siting of clean and renewable energy projects on contaminated (or formerly contaminated) lands. As part of this effort, EPA is evaluating the potential for energy projects on these properties and working with landowners and communities to identify ways to remove barriers to such projects.

In 2009, EPA and the Redevelopment Agency of Salt Lake City (RDA) entered into an Agreement & Covenant Not to Sue to facilitate “green” commercial redevelopment of the two properties owned by city within the site.

In February 2011, EPA, RDA, Gateway Parking L.C. and Salt Lake City signed a Successor Addendum to the Agreement. The Addendum allowed the RDA to step away from any further obligations under the Agreement and Gateway Parking L.C. to assume all of the remaining ones, except executing/recording an environmental covenant. Salt Lake City agreed to execute and record an environmental covenant. Gateway Parking, L.C. is also planning to acquire the property at the southeast corner of the site to develop a parking lot for the Gateway Development to replace parking lost during the reconstruction of the North Temple viaduct. Salt Lake City is still seeking partners for development of the remaining land.

Land Use Controls and Other Institutional Controls

Land use controls are the most common type of institutional control (IC). ICs are administrative or legal controls that help reduce the likelihood for human exposure to contamination. ICs can also help protect the integrity of the remedy. Examples of ICs are:

  • Zoning ordinances.
  • Environmental covenants.
  • Deed notices.
  • Well-drilling restrictions.
  • Building permits.
  • Informational advisories.

ICs, called for in the 1993 Record of Decision, have been implemented. They remain in place and all uses and/or activities at the site are consistent with the ICs.

In March 2011, Salt Lake City recorded an environmental covenant that places activity/use limitations on the properties specified in the Agreement & Covenant Not to Sue. These properties, previously owned by PacifiCorp, encompass the area formerly known as ABY (American Barrel Yard.) Generally, the environmental covenant prohibits the use of groundwater, discloses the presence of potentially contaminated soil below the excavated depth and prohibits land uses that would interfere with or adversely affect current/future remedial activities at the site.

Five-Year Reviews

EPA or the lead agency conducts five-year reviews following the start of a Superfund cleanup when contamination is left on the site. These reviews are repeated every five years. We use these reviews to determine:

  • How the remedy is working.
  • If the remedy remains protective of human health and the environment.

Five-year reviews for this site are statutory. The third five-year review report is posted in Site Documents below. The next review will be conducted in 2016.
