SHELLER GLOBE CORPORATION DISPOSAL IOWA EPA ID# IAD980630750 EPA Region 7 City: 4 miles northwest of Keokuk County: Lee County Other Names: Grimes Property 09/09/2008 SITE DESCRIPTION From 1948 until 1972, waste materials were taken to the Sheller-Globe Corporation Disposal site from the former Sheller-Globe plant in Keokuk, Iowa. The plant manufactured rubber products and automobile parts. Some of the waste material taken to the site for disposal consisted of solvents and paint sludges. These sludges, along with other non-hazardous wastes brought to the site, were periodically burned and the ash was spread over the hillsides. In 1972, use of the site for disposal stopped and the area was covered with soil. In 1980, the 6.6 acre site was sold and became the location of a house with a domestic well water supply. Based on environmental data collected during EPA investigations in 1986 and 1987, the site was added to the National Priorities List (NPL) in 1990. In the fall of 1991, the residents of the house were permanently relocated. In October 1990, EPA and Sheller-Globe entered into an Administrative Order on Consent that required Sheller-Globe to conduct a Remedial Investigation/Feasibility Study to determine the nature and extent of contamination at the site and evaluate alternatives to address contamination at the site. The Remedial Investigation (RI) field activities included sampling of ash material, surface soil, subsurface soil, surface water, sediments, and shallow and deep ground water. The analytical results of the samples were used to characterize the risk posed by the site conditions to human health and the environment. The RI and subsequent human health and ecological risk assessments indicate that the metals concentration in the ash material is the primary source of contamination. Based on the results of the RI and the human health risk assessment, no remedial action was necessary with regard to surface water, sediments, and ground water. In addition, the majority of local residents obtain drinking water from one of two rural water districts. The ecological risk assessment concluded that site conditions did not appear to present a significant threat to the environment. Site Responsibility: NPL LISTING HISTORY ------- This site is being addressed through Federal and potentially responsible parties' actions. Proposed Date: 05/05/89 Final Date: 08/30/90 Deleted Date: 09/24/2001 THREATS AND CONTAMINANTS / The RI and subsequent human health and ecological risk assessments indicate that the metals concentration in the ash material is the primary source of contamination. Accidental ingestion of contaminated soil and ash may pose a potential health threat. Based on the results of the RI and the human health risk assessment, no remedial action was necessary with regard to surface water, sediments, and ground water. The ecological risk assessment concluded that site conditions did not appear to present a significant threat to the environment. The Record of Decision (ROD) for the Sheller-Globe Corporation Disposal site was signed on September 20, 1995. Based on the findings of the RI and the Base Line Risk Assessment (BLRA), a remedial action objective (RAO) for this site was established to aid in the development and screening of remedial alternatives in the ROD. The RAO for this site, as stated in the February 1995 FS Report, is to control future use of the property to minimize potential for exposures. The selected remedy described in the September 1995 ROD addressed the threat posed by the contaminants within the primary disposal area of the site and required the following actions: • Record restrictive covenants/deed restrictions with the Lee County Recorder's office to prohibit the disturbance of the surface or subsurface of the property and limit land use to nonresidential. • Demolish the house and shed located onsite to prevent it from being used. • Remove all drums exposed at the ground surface (the drums were determined to be empty or filled with nonhazardous material). • Construct a soil and vegetation cover over the exposed ash and over the basement of the house. ------- • Inspect and maintain the soil covers. In addition, the Sheller-Globe Corporation Disposal site has been listed on the State of Iowa's Registry of Confirmed Hazardous Waste or Hazardous Substance Disposal Sites since 1989. Inclusion on this registry provides that written approval by the director of the IDNR is necessary prior to substantially changing the manner in which the site is used or selling, conveying, or transferring title of the site. CLEANUP APPROACH Response Action Status Site Facts: ------- ENVIRONMENTAL PROGRESS A Consent Decree, Civil Action No. 8-98-CV-90150, was negotiated and executed by the United Technologies Automotive Systems, Inc., Miriam and David B. Grimes (the property owners), and the United States of America. United Technologies Automotive Systems, Inc. (UTAS) is now known as United Technologies Corporation (UTC). The Consent Decree was lodged with the U.S. District Court for the Southern District of Iowa on September 25, 1998, and subsequently entered by the Court on March 3, 1999. The remedial action was conducted in accordance with the April 1999 Remedial Design/Remedial Action (RD/RA) Work Plan by United Technologies Automotive Systems, Inc. (formerly Sheller-Globe Corporation) and their technical contractors (URS Corporation and WRS Infrastructure and Environment). The field work associated with the remedial action was conducted between November 1, 1999 and November 11, 1999. A backhoe was used to demolish the house and shed, the basement floor slab was broken up in place, and all the debris from the house and shed (as well as the empty drums and miscellaneous debris) was placed within the basement of the house. An initial layer of clay was placed over the debris prior to placement of a non-woven geotechnical filter fabric over the limits of the house. Three 8-inch thick lifts of clay were placed over the filter fabric and then a 12-inch layer of topsoil was spread over the clay. Each lift of clay and topsoil were compacted and sloped to specifications. The four areas of exposed ash that were identified during the RI/FS were also covered with at least one foot of topsoil. The house area, the four ash areas, the shed area, and drum divots were seeded and erosion control mats were spread and staked over the completed soil areas. EPA conducted a pre-certification inspection on November 8, 1999. In an April 21, 2000 letter to UTAS, EPA indicated that the Remedial Action (RA) Report adequately demonstrated completion of the outstanding items noted during the pre-certification inspection and that the remedial action had been performed in accordance with the Consent Decree and RD/RA Work Plan. The signed Statement of Completion was submitted by UTAS with the final RA Report on May 22, 2000. Land use restrictions are also a component of the remedy described in the ROD. In accordance with the Consent Decree, the property shall not be used for residential purposes and there shall be no disturbance of the surface or subsurface of the land. The Environmental Protection Declaration of Restrictive Covenants describes the land-use restrictions associated with the property and sets forth the procedures to enforce said restrictions. On September 12, 2000 this document was recorded at the Recorder's Office of Lee County, State of Iowa. The Sheller-Globe Corporation Disposal site was deleted from the NPL on September 24, 2001. The remedy is functioning as intended by the ROD. The Remedial Action has been completed to address the risks associated with the RME scenario. The main components of the selected remedy as described in the September 1995 ROD included: 1) restrictive covenants/deed restrictions that prohibit the disturbance of the surface or subsurface of the property and limit land use to nonresidential; 2) soil and vegetative covers over areas of exposed ash material; and 3) demolition of the house and shed located onsite to prevent future use. The Environmental Protection Declaration of Restrictive Covenants describes the land-use restrictions associated with the property and sets forth the procedures to enforce said restrictions. On September 12, ------- 2000, this document was recorded at the Recorder's Office of Lee County, State of Iowa. The semi-annual and annual inspections have confirmed that the soil and vegetative covers are competent, and that the land remains vacant. Routine field inspections by representatives of UTAS to assure the integrity of the soil and vegetative covers have been conducted in 2000, 2001, 2002, 2003, 2004, and 2006. These inspections have also verified compliance with the restrictions in the Environmental Protection Declaration of Restrictive Covenants (i.e., the property is not being used for residential purposes and the land surface of the property has not been disturbed). On behalf of UTAS, URS Greiner Woodward Clyde conducted the initial post-remedial action inspection in April 2000. Recommended maintenance actions that were taken included additional seeding and placement of erosion control material in limited areas. The ground surface had not been disturbed and the property was vacant. Subsequent site inspections (i.e., September 2000, April 2001, September 2001, April 2002, September 2002, September 2003, September 2004, and September 2006) have also revealed that the ground surface remains undisturbed and the property remains vacant. These inspections have verified the continuing development and integrity of the soil and vegetative covers that were constructed during the remedial action. The First Five-Year Review Report, dated August 2005, was prepared by U.S. Environmental Protection Agency (EPA) Region VII. This is the first five-year review for the Sheller-Globe Corporation Disposal Site and it concluded that the remedy at Sheller-Globe Corporation Disposal Site is protective of human health and the environment. The most recent post-remedial action inspection was conducted in Septembrer 2006. The post-remedial action inspections will continue in accordance with the following schedule: Fall 2008, and Spring 2010. These inspections will be conducted by UTC to provide information for the second Five-Year Review for the Sheller-Globe Corporation Disposal site which will be completed in 2010. COMMUNITY INVOLVEMENT In March 2005, a notice stating that the five-year review process was underway was placed in two local newspapers in Keokuk, (i.e., the Daily Gate City and the Free Press). A March 2005 information sheet, or Fact Sheet, was sent to all entities on the site mailing list inviting the recipients to submit any comments to EPA. Similarly, the completion of the August 2005 Five-Year Review Report and its availabilty at the Keokuk Public Library and EPA Region 7 office was announced. ------- SITE REPOSITORY Contact the Region 7 Superfund Community Relations Office at (913) 551-7003 Superfund Records Center 901 N. 5th St. Kansas City, KS 66101 Mail Stop SUPR (913)551-7166 Keokuk Public Library 210 N. 5th Keokuk, Iowa 52632-5614 (319) 524-1483 REGIONAL CONTACTS SITE MANAGER: E-MAIL ADDRESS: PHONE NUMBER: Jim Colbert colbert.jim@epa.gov (913)551-7489 COMMUNITY INVOLVEMENT COORDINATOR: PHONE NUMBER: E-MAIL ADDRESS: STATE CONTACT: PHONE NUMBER: Beckie Himes (913)551-7253 himes.beckie@epa.gov Bob Drustrup, IDNR (515)281-8900 MISCELLANEOUS INFORMATION STATE: IA 079C CONGRESSIONAL DISTRICT: 02 EPA ORGANIZATION: SFD- SUPR/EFLR MODIFICATIONS Created by: Karla Created Date: 01/09/98 12:57 PM Asberry/SUPRFUND/R7/US EPA/US Last Modified by: Beckie Last Modified Date: 09/09/2008 01:14 PM ------- Himes/R7/U SEP A/U S ------- |
