Initial inspections are required on all systems. Initial inspection is defined as the first inspection after the effective date of this regulation, which is Oct. 11, 1997. UST systems that have not been inspected for the first time must be inspected as follows:
|Tank Installation Date
||Initial (or first-time) Inspection is required:
|Tanks installed before Dec. 1, 1989
||by Oct. 11, 1999
|Tanks installed between Dec. 23, 1989 and Oct. 11, 1997
||by Oct. 11, 2002
|Tanks installed after Oct. 11, 1997
||6 to 12 months after installation
Some UST systems have already been initially inspected. In those cases, subsequent inspections are required every three (3) years. Any time there is a change in ownership, a facility inspection must be completed six to 12 months after the ownership change. The department may require additional inspections to protect the environment. The owner will be notified in writing if an additional inspection is necessary.
If a modification was performed in order to bring the tank or tank system into compliance, an UST Modification Report form must be used to report the activities completed. A certified installer (UMX) must be hired to do the work. The UST Modification Report must be submitted to DEP within 30 days of completing the tank handling activity.
Tank owners are reminded that only inspectors certified by DEP in the underground tank inspector category (IUM) can perform facility inspections.
