Guidance for Motor Fuel Suppliers

Regulated storage tank systems, such as those containing motor fuel, are required to be registered with DEP. The department routinely discovers such systems, especially aboveground systems, that are in-service and not registered. The department is undertaking an outreach initiative to provide basic information to motor fuel suppliers to ensure all regulated systems are properly registered. For more information, please view the guidance with contact information specific to your district.
