What & Where
On October 11, 1997, DEP adopted regulations pertaining to periodic inspections of UST systems. These inspections have been called Facility Operations Inspections (FOI) and are used to determine the tank system’s integrity and suitability for continued use. The FOI includes the review of records pertaining to the installation, release detection monitoring, and maintenance of the UST system. The FOI also includes a physical inspection of all equipment which can be examined and observed aboveground, through manways, or other access methods.
As a storage tank owner or operator, you should have your UST system prepared for physical inspection on the date agreed upon with your IUM.
You should also prepare the following records for your inspector:
- Release Detection Records
- Monthly tank and piping release detection checks
- Periodic evaluations
- Spill Prevention and Overfill Prevention Evaluations
- Modification Reports
- Corrosion Protection records
- Tank and Piping Construction records
- Operator Training Certificates and List of Designated Class A/B and C operators
- Records of participation in the Underground Storage Tank Indemnification Fund (USTIF)
- Copies of other records relevant to your USTs

DEP led Inspections
DEP may conduct inspections at your facility with or without notice.
Please note: DEP Inspections do not replace your required 3rd party Facility Operations Inspection.
These inspections may occur in response to information reported on your most recent FOI, compliance history trends, or to verify DEP records are accurate and complete.
DEP inspectors may examine the accessible physical components of your UST system, operation of release detection equipment, operation of overfill alarms, and request review of records pertinent to your UST system. DEP Inspectors may also interview Class A, Class B, and Class C operators to ensure the UST system is being operated in compliance with pertinent regulatory requirements.
At the completion of a DEP inspection, you or your designated operators will receive an inspection report which notes the compliance status of your facility during that inspection.
