3.0 Suitability for Service The Newport Airport 10,000 gallon AVGAS tank was inspected and tested in accordance with all applicable requirements of STI SP001 September 2011 5th Edition. This tank is considered to be in a noncompliant state since there are corrosion related holes present within the outer shell that require mechanical repairs.
Per STI SP001 the tank is classified as a Category 1 and should be inspected monthly and annually by the owners inspector as required by Section 6.0 of STI SP001. Formal External Inspections shall be performed as required by the owner’s SPCC plan and established schedule.

4.0 Summarized Recommendations Based on the inspection completed this tank is a Category 1 in accordance with STI SP001, 5th Edition. The following section summarizes the recommendations which are based on the findings in the preceding checklists.
Foundation: 1) The tank saddle supports have localized areas of heavy coating degradation and scale accumulation. The customer should properly clean and recoat the affected locations to prevent further deterioration. Shell & Heads: 1) There was 5-6 corrosion induced thru holes discovered on the top of the secondary shell while scraping scale. They are adjacent to a guide bracket used for the old level glass in an approximate 8” x 16” area. These holes should be enclosed as soon as possible to inhibit rainwater intrusion into the annular space. A temporary soft patch consisting of fiberglass or epoxy materials will suffice as a temporary fix until permanent mechanical repairs; such as filet welded patch plates, can be installed as required by STI SP-001 10.2.4. Note: The tank will remain in a non-compliant state until permanent repairs are completed. 2) There were scattered areas of localized coating failure and blistering present in various sizes with heavy scale buildup. Manual scraping revealed corrosion measuring 0.02” to 0.04” deep at these locations. Since holes have been discovered in similar areas on the top of the tank, it is strongly advised to prep and recoat these locations at the next opportunity.
Nozzles, Manways & Connections
1) The manway flanges and covers pertaining to appurtenances D & K, exhibited heavy coating failure and scale accumulation on all surfaces that included the gasket region, necks and around bolting. The customer should highly consider separating these components, cleaning and re-inspecting for a better evaluation. Pending results, these components should be recoated.
2) The coupling threads, plugs and adjacent components had light to moderate coating failure with oxidation occurring. The customer should prep and recoat these components at the next convenience.
3) Appurtenance C had heavy coating failure and scale accumulation between the flanges. The customer should highly consider
separating these components, cleaning and re-inspecting for a better evaluation. Pending results, these components should be recoated.
Miscellaneous 1) The fill, offload and leak detection piping had areas of heavy coating failure with scale and minor corrosion forming. The customer should prep and recoat these components at the next convenience.

The periodic AST inspection is intended for monitoring the external AST condition and its containment structure. This visual inspection does not require a certified inspector. It shall be performed by an owner’s inspector who is familiar with the site and can identify changes and developing problems. Remove promptly upon discovery of standing water or liquid in the primary tank, secondary containment area, interstice or spill container. Before discharge to the environment, inspect the liquid for regulated products or other contaminants and dispose of it properly. In order to comply with EPA SPCC (Spill Prevention, Control and Countermeasure) rules, a facility must regularly test liquid level sensing devices to ensure proper operation (40 CFR 112.8(c)(8)(v)). (*) designates an item in a non-conformance status. This indicates that action is required to address a problem. Non-conforming items important to tank or containment integrity require evaluation by an engineer experienced in AST design, a certified inspector, or a tank manufacturer who will determine the corrective action.

3.0 Suitability for Service The Newport Airport 10,000 gallon AVGAS tank was inspected and tested in accordance with all applicable requirements of STI SP001 September 2011 5th Edition. This tank is considered to be in a noncompliant state since there are corrosion related holes present within the outer shell that require mechanical repairs.
Per STI SP001 the tank is classified as a Category 1 and should be inspected monthly and annually by the owners inspector as required by Section 6.0 of STI SP001. Formal External Inspections shall be performed as required by the owner’s SPCC plan and established schedule.

4.0 Summarized Recommendations Based on the inspection completed this tank is a Category 1 in accordance with STI SP001, 5th Edition. The following section summarizes the recommendations which are based on the findings in the preceding checklists.
Foundation: 1) The tank saddle supports have localized areas of heavy coating degradation and scale accumulation. The customer should properly clean and recoat the affected locations to prevent further deterioration. Shell & Heads: 1) There was 5-6 corrosion induced thru holes discovered on the top of the secondary shell while scraping scale. They are adjacent to a guide bracket used for the old level glass in an approximate 8” x 16” area. These holes should be enclosed as soon as possible to inhibit rainwater intrusion into the annular space. A temporary soft patch consisting of fiberglass or epoxy materials will suffice as a temporary fix until permanent mechanical repairs; such as filet welded patch plates, can be installed as required by STI SP-001 10.2.4. Note: The tank will remain in a non-compliant state until permanent repairs are completed. 2) There were scattered areas of localized coating failure and blistering present in various sizes with heavy scale buildup. Manual scraping revealed corrosion measuring 0.02” to 0.04” deep at these locations. Since holes have been discovered in similar areas on the top of the tank, it is strongly advised to prep and recoat these locations at the next opportunity.
Nozzles, Manways & Connections
1) The manway flanges and covers pertaining to appurtenances D & K, exhibited heavy coating failure and scale accumulation on all surfaces that included the gasket region, necks and around bolting. The customer should highly consider separating these components, cleaning and re-inspecting for a better evaluation. Pending results, these components should be recoated.
2) The coupling threads, plugs and adjacent components had light to moderate coating failure with oxidation occurring. The customer should prep and recoat these components at the next convenience.
3) Appurtenance C had heavy coating failure and scale accumulation between the flanges. The customer should highly consider
separating these components, cleaning and re-inspecting for a better evaluation. Pending results, these components should be recoated.
Miscellaneous 1) The fill, offload and leak detection piping had areas of heavy coating failure with scale and minor corrosion forming. The customer should prep and recoat these components at the next convenience.

There were scattered areas of localized coating failure and blistering present in various sizes with heavy scale buildup. Manual scraping revealed corrosion measuring 0.02” to 0.04” deep at these locations. There was 5-6 corrosion induced, thru holes discovered on the top of the secondary shell while scraping scale. They are adjacent to a guide bracket used for the old level glass in an approximate 8” x 16” area. There were no bulges, dents or cracking observed.
