501 N. Santa Fe Site

The 501 North Santa Fe Site (Site) is a former grain handling facility located at the northwest corner of the intersection of North Santa Fe Avenue and North Street in Salina, Kansas, which is in Saline County. The facility property is zoned for light industrial use by the City of Salina. Land use to the north, south, east, and west of the facility includes a mix of industrial, commercial, and agricultural properties. Residential properties are located more than 1,200 feet to the north and southwest of the facility. The Site property is currently owned by Earlco, Inc., and is used as a warehouse and storage yard. The Site also includes areas in which contaminants of concern (COCs) have been released and/or have migrated or emanated off the property.

Public Notice

KDHE is soliciting public comments regarding a proposal to address environmental contamination at the Site. A draft Corrective Action Decision (CAD) document that outlines the proposal for cleanup is available for public review on this webpage, at the KDHE offices in Topeka, and at the Salina Public Library. Appointments to review documents in Topeka may be made by calling Pamela Green at 785-296-1935.

Public comments can be submitted by email or in writing to Pamela Green, KDHE Bureau of Environmental Remediation, 1000 SW Jackson Street, Suite 410, Topeka, KS 66612. Comments will be accepted from November 1 – 30, 2023.

Site History

The Site historically operated as an active grain storage and milling facility from the 1940s until 1991. The facility originally consisted of a large mill to the north; a series of grain storage elevators to the northeast; an office building to the east; and a brick building located along the southern site boundary, which was used as a laboratory and then as a power plant for milling operations. The Site property currently consists of the former powerhouse building, which is now used to store warehousing building materials and concrete construction equipment. The historic elevators and milling building are still in place but are considered off-site for the purposes of this CAD.

Site Investigation

In March 2001, carbon tetrachloride, chloroform, and 1,2-dichloroethane (1,2-DCA), as well as several other chlorinated hydrocarbons and petroleum compounds, were detected in groundwater during KDHE’s preliminary assessment of the Elm and Front Street Site. The distribution of contaminants in groundwater suggested that a grain handling facility located on the northwest corner of Santa Fe Avenue and North Street was a source area. A leaking above-ground storage tank (AST), formerly located at the northeast corner of a brick building at the Site, released grain fumigants composed primarily of carbon tetrachloride in late 1969 or early 1970's and is believed to have contributed to the groundwater contamination. 

After no active, viable responsible party for the grain fumigant release could be found, the Site was transferred to the Orphan Sites Unit in 2005. KDHE conducted a series of investigations to delineate and characterize the source area and to evaluate possible source removal options. Results of a 2005 investigation identified elevated concentrations of carbon tetrachloride, 1,2-DCA and other constituents in soil at the former location of the AST. Groundwater sampling identified a long narrow plume of carbon tetrachloride and 1,2-DCA originating from the source area towards the City of Salina's downtown public water supply well field. 

In 2007, Koch Agriculture Company (KAC) entered into a Settlement Agreement and Consent Order with KDHE under the State Cooperative Program to conduct a Comprehensive Investigation (CI) and Corrective Action Study (CAS) at the Site. The CI was conducted in phases from 2007-2009 and included collection of soil and groundwater samples, installation of monitoring wells and membrane interface probes, and hydraulic testing. A CI Report and CI Addendum 1 Report were approved by KDHE in 2009 and 2010, respectively.
