TUBA CITY, Arizona, December 3, 1999 (ENS) - The U.S. Environmental Protection Agency 
(EPA) has approved a pilot plan to begin cleanup of the underground gasoline plume 
originating from the Tuba City Thriftway and SunWest (also known as Navajo Trails and 
Super Fuels) gas stations. The cleanup on the Thriftway leasehold is expected to start 
by late February. EPA has directed the owners of the SunWest and Thriftway facilities 
to come up with a cleanup plan for a second area near the existing evaporation ponds 
on the south side of Highway 160.

In 1996, EPA ordered the two gas stations 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. While the 
plume has migrated a short distance off the leaseholds, it does not pose a threat to 
any drinking water sources in the Tuba City/Moenkopi area. The plume is still far from 
the Upper and Lower Village's drinking water sources. Cleanup measures are expected to 
remove the contamination long before it threatens these water supplies. EPA and tribal 
inspectors also investigated four nearby gas stations in November and found poor leak 
monitoring practices, inadequate leak detection record keeping, and other violations 
of the federal underground tank rules.
