Posted by [EMAIL PROTECTED] : CLEANUP BEGINS ON ARIZONA UNDERGROUND GASOLINE SPILL http://ens.lycos.com/ens/dec99/1999L-12-03-09.html 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.
