The Oil Control Program has highly trained staff to help companies and individuals ensure that their Underground Storage Tanks (USTs) are in compliance with State and federal regulations. Click here for UST Compliance Outline to determine the requirements for your tank.

The Oil Control program administers several certification programs to ensure UST Removers, Technicians and Inspectors are qualified to perform this work.  For additional information, click here for UST Certification Programs.
