Above Ground Storage Tanks

The Oil Control Program has highly trained staff to help owners ensure that their Above Ground Storage Tanks (ASTs) are in compliance with State and federal regulations. ASTs with capacities of 1,000 gallons of used oil or 10,000 gallons or more of virgin oil are required to have oil operations permits issued by the Oil Control Program.

All regulated ASTs are required to have secondary containment, such as dikes. Other requirements for regulated ASTs can be found in COMAR 26.10.01. The Oil Control Program is available to assist in reviewing plans.

Residential and farm AST systems are usually for home heating. The following fact sheet may be of interest to homeowners:
