Regulated Tank List

Information on registered storage tanks is available in several formats for online access or downloading. Fact sheet #1566, Storage Tank and Spill Prevention Act - An Overview (PDF) describes the types of tanks that require registration. The information on this page includes registered, regulated storage tanks, except aboveground tank systems storing highly hazardous substances, and aboveground tank systems with a capacity greater than 21,000 gallons (because of the sensitive nature of the information). Home heating oil tanks are not regulated and are not part of this list. The information is derived from DEP's eFACTS (Environment, Facility, Application, Compliance Tracking System) database.

For questions or printed information pertaining to regulated storage tanks, please contact the Storage Tank Program's Customer Service at 800-42TANKS (PA Only) or 717-772-5599.
