The Ilada Energy Company site is a 16.743 acre abandoned tank farm which formerly had twelve million gallons of tank storage capacity. The facility is located southeast of East Cape Girardeau in a rural setting next to the Mississippi River levee. In the 1980's the site was found to contain oil, sludge, and contaminated water, some of which contained a variety of hazardous and toxic substances including toxic heavy metals, industrial solvents, and polychlorinated biphenyls (PCBs).
The site came under Illinois EPA scrutiny in 1982 when an inspection report showed that the Ilada Energy Company was improperly storing, handling, mixing, and disposing of waste oils contaminated with PCBs. Stained soil near several of the tanks prompted several sampling events and installation of several groundwater monitoring wells. These and subsequent sampling events led the United States Environmental Protection Agency (U.S. EPA) to list the site on the National Priorities List (NPL) in October 1989, and also led to a subsequent removal action at the site.
A 1989 Administrative Order on Consent (AOC) named Emerson Electric Company of St. Louis, MO., Granite City Division of National Steel Corporation, Metal Container Corporation of St. Louis, MO., and Shell Oil Company of Houston, Texas, as cooperating potentially responsible parties (PRPs). The AOC bound these parties to perform a removal action and conduct a remedial investigation (RI).
The RI report yielded information regarding the nature and extent of the contamination remaining at the site including the following:
- The site surface and subsurface soils contain generally low levels of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs).
- A localized subsurface pocket of aviation gasoline remains from the site's original use as a fuel storage depot approximately 40 years ago. The lateral extent of this pocket measures approximately 50 by 75 feet, and is entirely contained on the site.
- The adjacent properties to the south, east, west, and north are unavailable for future development because they were acquired in 1997 as part of a federal flood control program.
Site ResponsibilityThis site was addressed through federal, state, and potentially responsible party (PRP) actions.
Threats and ContaminantsPrior to the removal action (1989-1991), liquid oily wastes found on site were contaminated with VOCs, PCBs, and heavy metals including lead, arsenic, and zinc. On-site surface soils were contaminated with PCBs and heavy metals. The potential existed for site-related contaminants to migrate off-site into the sole source drinking water supply of area residents. Additionally, agricultural lands and the nearby Mississippi River could have been adversely affected by oily wastes and associated contaminants from the site.
The removal action began in December 1989 and was completed by March 1991. This action resulted in the removal of all tanks and their contents, piping, structures, and grossly contaminated soils. A total of 442,162 gallons of oil and sludge were burned as waste fuel in kilns, 142,700 gallons of PCB-contaminated oil and sludge were incinerated, 865,700 gallons of contaminated water were treated and discharged, 1,055 cubic yards of soil and miscellaneous debris were disposed as special waste, 637 cubic yards were disposed as demolition debris, 50 cubic yards of PCB-contaminated soil were landfilled, and 1,264 tons of steel were recycled by melting. Of the original on-site structures, only the repaired fence and the water well remain.
The RI for the site was completed and approved by Illinois EPA in April 1999. The baseline human health risk assessment (HHRA) and ecological risk assessment (ERA) were finalized and approved by Illinois EPA in July 1999. It was determined that no further remedial action is necessary at the Ilada Energy Company site. The earlier removal action has mitigated the environmental risks to a degree that the conditions at the site pose no unacceptable risk of exposure to contaminants of concern. A "No Further Action" Record of Decision (ROD) and the preliminary close-out report were signed in September 1999. The site was then deleted from the NPL on January 2, 2001.
Illinois EPA completed the first five-year review for the site in 2004. The report concluded that the remedy is protective of human health and the environment. A second five-year review was completed in August 2009. The site was found to be currently protective of human health and the environment. As a result of the second five-year review, an additional land-use restriction or Institutional Control (IC) was instituted at the site in order to better implement administrative control of site use. Another recommendation in the second five-year review was to develop an institutional control implementation action plan to ensure effective ICs have been implemented and remain in place and to ensure that long-term stewardship will ensure future protectiveness. Development of that plan is currently underway for the site.
Property ReuseThe site is currently owned by a private citizen. The private citizen is using the property for recreational activities; these activities include all-terrain vehicle usage and other natural resource recreation activities.
