Armstrong Motors Inc., owner of four underground gasoline storage tanks, has been charged with three counts of tank mismanagement by the Environmental Protection Agency.
EPA said the charges stem from an April inspection.
The underground storage tanks are located at the Budget Gas Station at 6-9 Estate Golden Rock in Christiansted.
The EPA said Armstrong Motors did not monitor leaks of underground piping, failed to provide a proper method to check the tanks themselves for leakage and did not keep records of any tightness tests for 1997.
The penalty for the infractions is $24,812.
A release from EPA called underground storage tanks "the number one source of groundwater contamination in the United States."
St. Thomas is facing a cleanup in Estate Tutu due, in part, to underground storage-tank leakage that contaminated the wells in the area.
