BACKGROUND

BASF is located at 3150 Highway JJ, Palmyra, Missouri, in Marion County. The BASF property occupies approximately 1,800 acres located in Sections 10, 11, 14, 15, 22, and 23 Township 3 South, Range 5 West, of which approximately 250 acres is subject to corrective action (Facility). The site is bounded by surface waters to the northwest (South River), the north (Mississippi River), the west (North River), and to the east and southeast (Rock Ridge Slough and the Bay de Charles).

In 1990, EPA issued BASF a Part 2 Hazardous and Solid Waste Amendments Permit and a Part 1 Missouri Hazardous Waste Management Facility Permit for the operation of a hazardous waste treatment and storage facility.

Between 1965, when they purchased the property, and 1979, American Cyanamid Company, now known as Wyeth Holding Corporation (and currently owned by Pfizer), built facilities for the following:

In 1971, the di-calcium phosphate production facility and 12 acres in the north-central portion of the facility were leased to Alpharma, which manufactured animal feed intermediates at the AFI Plant. Alpharma's manufacturing operations at the AFI Plant were discontinued in 2003.

In 1978 and 1979, the herbicide plant area was constructed after an explosion destroyed the original herbicide plant in 1977. The facility currently manufactures agricultural chemicals including herbicides and insecticides.

BASF purchased the facility on July 1, 2000, and is the current owner and operator; however, Wyeth Holdings Corporation (Pfizer) retains financial responsibility for certain historical environmental matters.

ENVIRONMENTAL INVESTIGATIONS AT BASF

In 1987, a Preliminary Review/Visual Site Inspection Report (VSI) at the facility documented the identification and inspection of 42 SWMUs and six areas of concern (AOCs). EPA recommended additional action or investigation at three of the SWMUs and four of the AOCs.

Based on the results of the RFI conducted at the site, five confirmed soil source areas were identified. In addition, four possible soil source areas were identified but could not be confirmed because of the presence of shallow groundwater and local elevated shallow groundwater concentrations.

Groundwater sampling conducted during the RFI indicated that two of the constituents of concern (Chlorobenzene, also known as monochlorobenzene or MCB, and 1,2-dichloroethane or 1,2-DCA) are consistently reported in the groundwater at the site. The concentrations and areal extent of MCB and 1,2-DCA varies between the three primary hydrostratigraphic units (shallow, intermediate, and deep) underlying the site.

PROPOSED FINAL REMEDY

EPA is proposing the following corrective measures to address contamination at the BASF facility:

Facility Groundwater Contamination Facility Soil Contamination
