NPL Site Narrative for Kerr-McGee Chemical Corp.(Soda Springs)
KERR MCGEE CHEMICAL CORP. (SODA SPRINGS PLANT)
Soda Springs, Idaho
Federal Register Notice: October 4, 1989Conditions at proposal (May 5, 1989): Kerr-McGee Chemical Corp. has produced vanadium pentoxide in southeastern Idaho 1 mile north of Soda Springs, Caribou County, since 1963. The 158-acre site is in a broad, flat valley near the western base of the Aspen Range. Significant agricultural crops in the area include wheat and hay. A number of other large industrial complexes are in the valley, including Monsanto Chemical Co., directly across State Highway 34 from Kerr-McGee. Monsanto supplies by-product ferrous-phosphate solids, which Kerr-McGee processes into vanadium pentoxide. The Monsanto plant is also being proposed for the NPL at this time.
Kerr-McGee's plant generates a number of liquid wastes and stores them in on-site ponds. The two largest ponds hold over 12,000 cubic yards of waste.
On-site monitoring wells and the ponds contain vanadium, arsenic, copper, and silver, according to tests conducted as part of an EPA site inspection in the summer of 1987. Within 3 miles of the site are public springs and private wells that provide drinking water to over 3,000 people and a private well that irrigates 165 acres. The plant receives drinking water from an on-site well 375 feet from a contaminated well. No unthreatened alternate source of water is available.
The topography in the area prohibits migration of contaminants to surface water.
Status (October 4, 1989): EPA's preliminary plan for fiscal year 1990 includes a remedial investigation/feasibility study to determine the type and extent of contamination at the site and identify alternatives for remedial action.
