The Jibboom Junkyard site is approximately 9 acres in size, although roughly 7 acres have been covered by an interstate highway (I-5). A former electric generating plant immediately north of the Jibboom site covers approximately 2 additional acres which have been addressed by State cleanup actions. The site, formerly owned by the Associated Iron and Metals Company, began operations in 1951. Operations included metal salvaging of a variety of materials such as railroad cars, army tanks, batteries, and electric transformers. Some scrap metal debris was disposed of on site, and transformer oil was poured onto the ground. Operations ceased in 1965, when the California Department of Transportation purchased the property. Following EPA's cleanup of the contaminated soil, the 2.3-acre uncovered section of the site used by the original salvage yard was transformed into a city park along the Sacramento River, the Robert T. Matsui Riverfront Park. State cleanup actions of the property north of Jibboom Park included removal of underground storage tanks and contaminated soil and fencing of some area around an historic old electric power generating plant. Approximately 10,000 people live within one mile of the site. The bicycle path on the river levee adjacent to the site receives regular traffic as a popular recreation route and during the week as a route to and from work. The city's drinking water is taken from the river along the western edge of the site. The site is in the flood plain for the Sacramento River.

The successful return of the clean Site for use as the Robert T. Matsui Riverfront Park has been acknowledged by EPA as an example of Superfund site reuse. Please click here to access this Return to Use Initiative Fact Sheet.

Contaminants and Risks

Contaminated Media
  • Soil and Sludges

Groundwater and soil were found to be contaminated with lead, PCBs and other contaminants related to waste metal processing. Coming into direct contact with or accidentally ingesting contaminated soil or groundwater posed a potential threat to human health before EPA's cleanup action.

Because the site was considered available for Unlimited Use/Unrestricted Exposure (UU/UE) use after completion, no post-cleanup review was required. Region IX elected to complete a discretionary Five-Year Review after the City of Sacramento approved preliminary development plans in that could increase residential land use in the vicinity of the site. The 2007 review (attached below) concluded that the remedy at Jibboom Junkyard remains protective of human health and the environment because residual concentrations measured in the soil are within the risk range for residential use. EPA worked with the California Department of Transportation (CalTrans) regarding the portions of the site buried beneath the elevated freeway built in 1965. CalTrans implemented the recommended notification procedures through their maintenance alert database and underground services alert system (see attached 9/11/2008 memorandum).

Investigation and Cleanup Activities

Initial Actions

Entire Site: In 1983, the site was fenced and soil samples were collected.

Cleanup Ongoing

From 1985 to 1987, over 11,000 cubic yards of contaminated soil were excavated and removed to an approved hazardous waste disposal facility. The remaining soil surface was tested to ensure protectiveness.

Cleanup Complete

Deletion from the National Priorities List: The site was deleted from the EPA's National Priorities List in September of 1991. Cleanup goals specified in Records of Decision have been met, institutional controls are in place, and all required reports and records are completed. EPA concluded that the cleanup levels of the soil at the site of the current Jibboom Park are protective of human health and the environment, and the site is available for unrestricted use and unlimited access. (UU/UE)

Cleanup Results to Date

The removal of contaminated soil and fencing eliminated the potential of exposure to hazardous materials at the Jibboom Junkyard site. All cleanup measures have been proven effective and the site was deleted from the NPL in September of 1991.

Potentially Responsible Parties

Potentially responsible parties (PRPs) refers to companies that are potentially responsible for generating, transporting, or disposing of the hazardous waste found at the site.

The PRP no longer exists (since 1965).
