     SAN FRANCISCO - - Cleanup technologies are being installed at the Tuba City Thriftway and SunWest (also known as Navajo Trails and Super Fuels) gas stations under a pilot plan approved last fall by the U.S. Environmental Protection Agency (EPA). Thriftway Corp. began installing the approved cleanup technologies to clean up the underground gasoline plume last week.  The installation of the pilot project is expected to last about two weeks.  

     The pilot project provides an opportunity to test the proposed cleanup technologies on the Thriftway leasehold.  These cleanup technologies have been proven effective in reducing concentrations of volatile organic compounds found in petroleum products at underground storage tank (UST) sites.  If the technologies work well, they may be used on the entire project area.  The Hopi Environmental Protection Office, the Navajo Nation, and the U.S. EPA will oversee the progress of the project.  

     In 1996 EPA ordered the Tuba City SunWest and Thriftway facilities to investigate underground contamination from leaking fuel tanks and pipes.  Since that time, over 80 monitoring wells have been installed to identify the boundaries of an underground petroleum plume and determine if there is groundwater contamination beyond the two facilities' leaseholds.

Details regarding the Thriftway gas station can be found at the following locations:
