About this file
This document is an inspection report for a diesel tank located at NSA Cutler in Cutler, Maine. The inspection was performed by Applied Technical Services (ATS) in general accordance with STI-SP001. The key findings include:
The tank was visually assessed and determined to be STI Category 1, with spill control and containment. Some minor issues were noted, such as scattered coating failure, surface rust, and light corrosion on the shell and heads. The normal venting was found to be undersized per UL-142 requirements. The report recommends the owner verify the venting capacity and address the coating deterioration. The recommended reinspection frequency is 5-10 years, which is considered a best practice for this type and size of tank.

STI-SP001 Category
ATS performed inspections in general accordance with STI-SP001. This report lists the results of inspection and provides a condition assessment of the equipment based upon the information gathered.
External inspections were performed from the ground and available ladders/platforms. External inspections were performed at areas that were safely accessible.
Foundation
Soil/earth is the foundation for this equipment. No visible deterioration or damage observed.
North Head
Scattered coating failure and surface rust observed throughout.
Shell
Scattered coating failure, surface rust, and light corrosion observed throughout.
Support saddles were observed. Scattered concrete deterioration observed.
Grounding Cables
This report identifies the over-pressure protection that was readily obvious during inspection. No determination of relief capacity was made by ATS. The owner should verify properly sized protection is provided for the system.
The tank was determined to be Category 1 per STI SP001. The basis for this determination is the spill control was observed to be the secondary containment, and the inherent CRDM was observed to be the tank is lifted off the ground.
The owner should verify the ability of the spill control to fully contain a release.
Normal Venting
None was observed on this equipment.
Overflow
None was observed on this equipment.
Nozzles
This was observed on the shell. No visible deterioration or damage observed.
Emergency Venting
Scattered coating failure and surface rust observed throughout.
South Head
Scattered coating failure and surface rust observed throughout.
Anchorage
Two grounding cables were observed. No visible deterioration or damage observed.

Analysis
This equipment was visually assessed in general accordance with STI-SP001. The results listed in this report are based upon the visual inspection performed, and does not include UT thickness data analysis (as UTT was not part of the inspection scope).
Secondary Containment
Two grounding cables were observed. No visible deterioration or damage observed.
An earthen berm was observed. The earthen berm contains tanks 103-AST-01 thru 103-AST-04 and is lined. No visible deterioration or damage observed.
Nameplate/Platforms/Ladders/Labels
The tank does not have a nameplate and labeling is missing and/or illegible due to weathering. Coating failure and surface rust on access platforms and ladders.
Additional Comments
The tank was stick tested; no water was found to be present. 99.5" of fuel was measured. Sensor/fill gauge is located in control room; the gauge reading was 99.7" of fuel.
Observation / Finding Action Item Priority
Priority 1 - High likelihood/consequence of failure (or) Critical code/standard deficiency (or) May not be fit for service without action
Priority 2 - Med likelihood/consequence of failure (or) Add'l info needed for evaluation (or) Action may be considered for continued service
Priority 3 - Low likelihood/consequence of failure (or) Non-critical code/standard deficiency (or) Best practice/preventative maintenance
Action items listed below are based on observations recorded at the time of inspection and/or findings determined during the post-inspection analysis. Priority "1", "2", "3" has been applied and is defined as:

Action Items 399868
Per UL-142, this tank requires a normal vent size of 2.5 inches and an emergency vent size of 8 inches. 6 inch normal venting was observed, and no emergency venting was observed.
These are cursory calculations based on observations at the time of inspection. The Owner should verify venting capacity satisfies the requirements of an applicable standard for the system operating parameters (e.g. API-2000, NFPA-30, UL-142).
2 Coating deterioration was observed.
Coat areas as necessary. Refer to coating provider for best surface preparation and coating application.
