ALEXANDER COUNTY
EAST CAPE GIRARDEAU
Congressional District # 12
ILADA ENERGY CO.
EPA ID# ILD980996789Last Updated: February, 2007
Site Description
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 to its addition to the National Priorities List (NPL) on October 4, 1989 and a subsequent removal action.
The 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 binded these parties to perform a removal action and conduct a remedial investigation.
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 (VOC's) and semi-volatile organic compounds (SVOC'S).
- 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 Responsibility
This site was addressed through federal, state, and potentially responsible party (PRP) actions.Threats and Contaminants
Prior to the removal action (1989-1991), liquid oily wastes found on site were contaminated with volatile organic compounds (VOCs), polychlorinated biphenyls (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.Cleanup Progress
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 IEPA in April 1999. The human health baseline 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 was signed in September 1999. This site was deleted from the NPL on January 2, 2001.
