Former River City Auto - Salmon
Cleanup at the former River City Auto—aka Beasley—property began in late summer 2006. The Salmon River Development Agency (SRDA) was awarded a $113,490 cleanup grant from the US Environmental Protection Agency (EPA). DEQ’s Brownfields Program, through its contractor, provided assessment data to determine the extent of contamination and to decide which cleanup method will be the most effective. The public was provided an opportunity to comment on the proposed cleanup methods. After leveraging additional cleanup and assessment funding from DEQ’s Leaking Underground Storage Tank and Brownfields programs, SRDA was able to complete the cleanup and close out the EPA Cleanup Grant. The completion report for the site is being developed and should be finalized in early 2012.
The property has been leased or subleased to various parties from 1969 to 1994, and has been primarily used as a gas station, service station, and convenience store. Other uses noted at the site were a used car lot from 1979 to 1982, and from 1982 to 1987, the site was occupied by the Salmon Chamber of Commerce.
In 1994, three underground storage tanks (USTs) were removed and samples were taken. Ground water and soil samples showed the presence of gasoline constituents at concentrations greater than DEQ standards. In 1996, DEQ and the owner entered into a Consent Order agreement to study the extent and impacts of the contamination. Ground water monitoring wells were installed in 1996, 1997, and 1998. In 1999, a 500-gallon used oil tank was removed, along with 180 cubic yards of soil, and free-phase product was discovered in one of the on-site monitoring wells. More monitoring wells were installed in 2000. In 2003, EPA conducted a removal assessment and collected more ground water and soil samples.
The SRDA purchased the property in 2005 with the intent of remediation and redevelopment. SRDA applied for and was awarded an EPA Cleanup Grant in 2005. SRDA applied for and was awarded a DEQ Brownfields Assessment Grant in 2006 to assess the extent of contamination. In addition, SRDA applied for and was accepted into DEQ’s Voluntary Cleanup Program.
Site Investigation Process
Through the Brownfields program, DEQ’s contractor performed additional site assessment work by sampling existing monitoring wells, installing three down gradient monitoring wells, collecting down gradient and up gradient ground water and soil samples, and performing a risk evaluation. Results are pending.
The former River City Auto building will be demolished and scrapped. After the site poses no risk to human health and the environment, through cleanup, the site will be redeveloped.

The City of Salmon is planning to build a Town Square Park on the west side of the property and will have access to the river once the property adjacent to the river is purchased and also converted into park space. The northeastern section of the property was tentatively going to be the new Salmon Library, and the city is planning that the southeast side of the property be office buildings.
