As of Thursday, about 6,000 gallons of gas had been cleaned up after about 20,000 gallons leaked from a Top Stop Convenience Store site in Manti and spawned a plume of contamination that has resulted so far in nearly $1 million in claims paid out.

Members of the Utah Solid and Hazardous Waste Control Board were given an update on the mess that last month prompted a civil lawsuit from apparel shop owner Lila Lee Christensen.

The plume appears to have stopped, the 50-60 gallons per day of gas being extracted from the plume is expected to increase and one family still hasn't been able to return to their home because of the plume, according to Brad Johnson, director of the Utah Division of Solid and Hazardous Waste's Environmental Response and Remediation.

"That home could not have been in a worse place relative to this plume," Johnson told board members Thursday in a meeting. He said cleanup efforts appear to be progressing "reasonably well."

Johnson said Top Stop officials are "committed" to cleaning up the leak, which Christensen is alleging ruined traffic into her dress shop and damaged the property. Top Stop is owned by Wind River Petroleum.
