Underground storage tanks (USTs), particularly older ones made of steel, may corrode and leak, releasing hazardous substances such as oil or fuel into the soil and groundwater.
Maryland environmental law and the 60-Hour Course emphasize that sellers must disclose known environmental hazards, and buyers should be aware of potential remediation costs.
The Maryland Department of the Environment (MDE) regulates USTs, requiring proper registration, maintenance, and closure procedures to prevent contamination.
