The Arizona Department of Environmental Quality and the Arizona Attorney General's Office announced Thursday that waste firms operating two western Arizona landfills have agreed to pay $58,000 in fines.
The Arizona Department of Environmental Quality said Allied Waste Industries Inc. and a subsidiary of Allied Waste agreed to the penalty under a consent judgment for solid waste violations.
Inspectors found soil contaminated by petroleum and hot lead slag was being used as landfill cover at the Allied Waste Industries' La Paz County Landfill south of Parker.
State inspectors found contaminated soil over a landfill slope and a 55-gallon drum of soil contaminated by used oil stored in a vehicle maintenance area during an inspection of the Copper Mountain Landfill near Wellton in Yuma County.
The consent judgment is subject to court approval.
