Aboveground Storage Tanks (AST) Program: An "Aboveground Storage Tank" or ‘AST’ means any tank or combination of tanks that is used to contain regulated substances and is not an underground storage tank. An AST system is any aboveground storage tank, connected piping, ancillary equipment, and spill containment system. Leak detections for ASTs must be performed by a certified tank installer.

Underground Storage Tanks (UST) Program: An Underground Storage Tank or 'UST' means a tank or any underground piping connected to the tank that has at least 10% or more of its combined volume underground (or beneath ground surface).

We also provide assistance to the USEPA inspectors with follow up site inspection for compliance with their enforcement actions in the CNMI. The US EPA and DEQ conduct follow up site inspection on a semi annual schedule during USEPA’s program review or evaluation of the UST Program. Also, USEPA conduct their inspection and issues enforcement action or citation to facilities that are non-compliance and/or violates the federal UST Regulations.
