February 2008 - Powerhouse Building, facing rear, 750 W. Wyeth St., Pocatello, Idaho

Site Background

Known since 1899 as the former Pocatello Power and Irrigation Company Powerhouse, the property was historically used as hydroelectric generation powerhouse and residence.

In 1902, the property was sold to the American Falls Power, Light and Water Company. In 1915, the property was bought by what later became Idaho Power Company. Shortly thereafter, the powerhouse building was closed.

In June 1998, Idaho Power sold the property to the Portneuf Greenway Foundation, a nonprofit group. In 2007, Poky Free Bikes, Inc. bought the property.

Site Investigation Process

DEQ contracted with Millennium Science and Engineering, Inc. (MSE) to perform a Phase I assessment on the property. The Phase I assessment was conducted in February 2008 and identified several areas of concern including:

  • Potential presence of radioactive phosphate slag
  • Stormwater drain and infiltration gallery
  • Underground storage tank (UST)
  • Potential PCBs
  • Potential asbestos-containing materials
  • Potential lead-based paints

DEQ again contracted with MSE to perform a Phase II assessment. The Phase II assessment consisted of assessing surface and subsurface soils for radionuclides, metals, VOCs, PCBs, and SVOCs. The building was assessed for lead and asbestos. A 500-gallon UST was removed and the inside of the building was assessed for indoor air concerns. The Phase II assessment was finalized September 23, 2008, and revealed lead-based paint around the building and some metals in soil near the infiltration gallery.


Cleanup was completed in 2009, and the site now operates as a community garden and bike shop/nonprofit that donates bike to the community. It also serves as a residence for folks involved with the garden and bike shop.
