On April 30, 2013, Region 10 filed a Consent Agreement and Final Order (CAFO) with E. Arlen Washines, Theresa Washines, and Da Stor at LillieÂs Corner. The Washines own and operate two UIC wells located at the retail gasoline service station, Da Stor at LillieÂs Corner, in Wapato, Washington on the Yakama Indian Reservation. The injection wells are an endangerment to an underground source of drinking water because they dispose of untreated fluids collected through open drains located on the facilityÂs fueling pads that may contain contaminants in concentrations which exceed the maximum contaminant levels established by EPA. The CAFO requires the Washines to close the injection wells by July 31, 2013, and, within 14 days of the final order, sample the transient non-community water system located on-site to determine whether it contains contaminants associated with motor vehicle fluids as a result of the violations. The CAFO assesses a $13,140 penalty.
