The BNSF Railway re-fueling depot...

at Hauser, Idaho was a controversial project when it was proposed and built, especially since it lies atop the Spokane Valley - Rathdrum Prairie sole source aquifer.  Two tanks hold a total of 500,000 gallons of diesel fuel to dispense to locomotives along the main rail line (click to enlarge):
The fuel is brought to the facility in 30,000 gallon tank cars that are individually off-loaded to the larger storage tanks seen above:
My environmental science seminar students toured the complex today in order to examine the environmental protections integrated into the facility.  Above ground storage tanks, double-lined piping, epoxy-sealed concrete platforms with two HDPE liners beneath them, are all designed to minimize accidental releases to the underlying aquifer.  Special thanks go to BNSF for allowing us to visit the operating industrial facility.
