Current Activities

Proposed Final Remedy Issued: On Aug. 27, 2014, the U.S. Environmental Protection Agency Region 7 issued a Statement of Basis in support of the proposed final remedy for soil and groundwater contamination at the BASF Corp. site. EPA proposed the current groundwater pump and treat system, a Soil Excavation Management Plan and an Environmental Covenant as the final remedy. EPA accepted written comments on the proposed final remedy during a 30-day public comment period, which ended Sept. 26, 2014. EPA is reviewing all written comments and will decide on the approved final remedy.

The public can review and copy the Statement of Basis and supporting documents at the Palmyra Bicentennial Public Library, 212 S. Main St., Palmyra, Missouri (during normal business hours) or the agency locations above.

Permit Application for Renewal: On Oct. 26, 1999, BASF Corp. submitted a permit application to the department and U.S. Environmental Protection Agency Region 7, to renew their existing Missouri Hazardous Waste Management Facility Part I Permit and Hazardous and Solid Waste Amendments Part II Permit. The department invites the public to review and offer written comments on the permit renewal application while the department conducts a technical review of the permit application.

Facility Description

The BASF Corp. site, known as the BASF Hannibal Plant, is located on about 1,800 acres at 3150 Highway JJ, approximately five miles northeast of Palmyra, along the west bank of the Mississippi River. About 250 acres of the site are used for plant operations. The remaining land is used for flood protection levees and agriculture. Before 1965, the property was used for agricultural purposes. In 1965, American Cyanamid Co., now known as Wyeth Holding Corp. and currently owned by Pfizer, purchased the property and built an ammonia storage and loading facility, ammonium nitrate production facility and a nitric acid production facility on the site in order to manufacture fertilizer products. American Cyanamid manufactured fertilizer products, which included nitric acid, ammonium nitrate and di-calcium phosphate. In 1971, the di-calcium phosphate production facility and 12 acres in the north-central part of the facility were leased to Alpharma, who manufactured animal feed intermediates until 2003. American Cyanamid built an insecticide production area in 1977 and another nitric acid production facility in 1978 and began manufacturing insecticides and herbicides. The herbicide plant was destroyed in 1977 after an explosion, and rebuilt in 1978 and 1979.

BASF purchased the facility in July 2000. Amvac, purchased a BASF product line and currently operates at the BASF facility. BASF currently manufactures agricultural chemicals, including herbicides and insecticides, at the Hannibal Plant. Commercial products manufactured at BASF include:

A variety of hazardous wastes are produced as part of the facility operations. BASF stores and incinerates both off-specification or expired product returned through their product stewardship program and waste created during the manufacture processes. BASF currently operates three hazardous waste container storage areas, with a combined capacity of 4,800 55-gallon containers, and four hazardous waste incinerators. The main raw materials currently and previously used at the facility that are considered hazardous constituents include monochlorobenzene (MCB), chloroform, 1,2-dichloroethane (1,2-DCA), methylene chloride, toluene and naphthalene.

Corrective Action Status

According to applicable state and federal hazardous waste laws and regulations, all hazardous waste treatment, storage and disposal facilities are required to investigate and clean up releases of hazardous waste and hazardous constituents to the environment at their facility resulting from present and past hazardous waste handling practices. BASF is the current owner and operator; however, Wyeth Holdings Corp. (Pfizer) retains financial responsibility for certain historical environmental matters. In 1987, AT. Kearney performed a Preliminary Review/Visual Site Inspection for the site, on behalf of EPA. The inspection was conducted to identify and gather information on actual and potential releases of hazardous waste and hazardous constituents to the environment. The report identified 42 solid waste management units and six areas of concern, of which EPA recommended additional investigation at three of the solid waste management units and four areas of concern.

The Fire Training Lagoon was investigated in October 1989. The subsurface sample results showed detections of total petroleum hydrocarbons. In December 1995 and January 1996, Geraghty & Miller Inc. performed a Geoprobeā„¢ Groundwater Assessment in the eastern half of the facility. The sample results showed detectable concentrations of 1,1-dichloroethane (1,1-DCA), 1,2-DCA, trans-1,2-dichloroethene (trans-1,2-DCE), chloroform, ethylbenzene, MCB and total xylene. In March 2000, EPA required further investigation of the impacted groundwater.

On behalf of BASF, Arcadis conducted a Phase I RCRA Facility Investigation, or RFI, from October through November 2003, and from September through March 2005. Arcadis conducted a Phase II RFI from July 2005 through May 2006. The main goal of the Phase I and Phase II RFI’s was to confirm and define the horizontal and vertical extent of any contamination source areas throughout the site. Based on analytical results, the investigation concluded the groundwater at the site is contaminated and identified five confirmed and four possible soil sources of contaminant release. The groundwater contamination includes 1,2-DCA, 1,1-dichloroethylene, benzene, MCB, tetrachloroethene, trichloroethylene, toluene and vinyl chloride.

BASF completed interim measures at the site in order to reduce or prevent unacceptable risks to human health and the environment. An interim measure is an action taken to temporarily control the contamination source or path the contamination could take from the source to humans, animals, or the environment, such as air, soil, water, and food. As an interim measure, BASF finished building a groundwater pump and treat system in July 2010. The system uses extraction wells to remove the contaminated groundwater and then treats the water through air stripping.

BASF performed a Corrective Measures Study to identify and evaluate possible remedial alternatives for the soil and groundwater contamination. BASF sum bitted the final Corrective Measures Study Report to the department and EPA in October 2011. The report includes BASF’s preferred final remedy along with other remedial alternatives. EPA, in coordination with the department, selected the best remedy given site-specific considerations for each solid waste management unit and area of concern. EPA prepared a Statement of Basis that summarized the remedial alternatives and EPA’s basis of support for the proposed final remedy. The public was invited to review and comment on the proposed final remedy during a 30-day public comment period. EPA is reviewing all written comments and will decide on the approved final remedy.

Regulatory Status

BASF is operating and conducting corrective action activities under two hazardous waste permits, one issued by the department and one issued by EPA. The department issued the Missouri Hazardous Waste Management Facility Part I Permit, effective April 25, 1990. EPA issued the Hazardous and Solid Waste Amendments Part II Permit, effective May 30, 1990. These permits allow BASF to store and incinerate both off-specification or expired product returned through their product stewardship program and waste created during the production processes. The regulated units consist of four hazardous waste incinerators and two hazardous waste container storage areas. These permits also require corrective action for releases of hazardous waste and hazardous constituents to the environment.

BASF submitted a permit application on Oct. 26, 1999, for renewal of their existing hazardous waste permits. BASF replaced that application with a new application on March 4, 2003, and sent an amendment to the permit application on Jan. 29, 2010. The facility's existing Part I Permit expired April 25, 2000, and Part II Permit expired May 25, 2000. State and federal regulations, 40 CFR 270.51, allow the existing hazardous waste permits to continue in effect until the department and EPA issue or deny new hazardous waste permits. The department determined the permit application was complete on May 5, 2010. The department is conducting a technical review of the permit application.
