Nearly 30 years after a diesel fuel spill at the AT&T Delta RS Communications Facility, a corrective action plan has been submitted and contaminated soil and water beneath the surface will be treated.
The action plan was filed with the Utah Division of Environmental Response and Remediation. It was prepared by Certified Environmental Consulting Inc. for AT&T.Officials said an accidental release of 3,000 to 4,000 gallons of diesel fuel occurred in the 1960s at the site, about six miles southeast of Delta. The fuel was spilled on the surface above underground storage tanks, seeping into the ground.
The tanks were removed in 1991 and the extent of contamination studied. It is estimated that 1,800 cubic yards of soil was affected, and floating product was found on a shallow aquifer about 13 feet below the surface.
The plan calls for excavating the contaminated soil, placing it in an on-site biotreatment cell, and pumping contaminated ground water through a treatment system. The soil and water will be treated until it is within the recommended water quality criteria as required by the state.
A copy of the plan will be available in the Delta Public Library.
