1.0 EXECUTIVE SUMMARY

The tank AST 1 diesel fuel storage tank was found to meet or exceed the minimum code requirements of STI SP-001 and the West Virginia code and regulations. This tank is built to API 650 code standards.

The tank has some minor issues with coating failure that should be managed at customer discretion.

The tank foundation and containment have areas with cracking and spalling which needs to be properly sealed to ensure no product can escape the containment in the event of a release.

The tank bottom-to-foundation seal has failed in areas and should be repaired to ensure protection against water seepage beneath the bottom of the tank floor and to help protect against tank floor bottom side corrosion.

Thickness measurements were taken and locations identified in this report.

The UT examination shows no significant wall loss deeming the tank structurally sound.

Tank AST 1 diesel fuel storage tank is found to be fit for continued service.

Please refer to the results and recommendation sections of this report for other minor discrepancies and recommendations that were identified during the course of this inspection.

3.1.3 The concrete foundation has some cracking and spalling throughout.

3.1.4 The tank bottom-to-foundation sealant has failed in some areas.

3.2 Shell:

3.2.1 No deformation or significant wall loss was found on the tank shell courses. The tank shell has some minor issues with coating failure but is in overall satisfactory condition.

3.3 Nozzles:

3.3.1 Tank nozzles appear to be in satisfactory mechanical condition with the appropriate, required, valves and instrumentation for venting.

3.4 Roof:

3.4.1 Tank roof is of a fixed cone design and found to be in satisfactory condition.

3.7 Other:

3.7.1 The tank access stairway has minor coating failure.

4.0 RECOMMENDATIONS

4.1 Foundation:

4.1.1 The concrete containment and foundation should be properly sealed to ensure adequate containing capabilities in the event of a release.

4.1.2 The bottom-to-foundation gap should be properly sealed to protect against water seepage beneath the bottom of the tank floor and to help protect against tank floor bottom side corrosion.

4.2 Shell:

4.2.1 Consideration should be given to the cleaning and re-coating the tanks external surface.

4.3 Nozzles:

4.3.1 Clean and recoat nozzles as needed.

4.4 Roof:

4.4.1 Clean and re-coat tank roof and components as needed to ensure proper against surface oxidation.

4.5 Floor:

4.5.1 None

4.6 Ancillary Equipment:

4.6.1 None

4.7 Other:

4.7.1 Consideration should be given to the cleaning and re-coating of the access stairs as needed.

4.8 Next Inspections:

4.8.1 Next internal inspection is due by:

4.8.2 Next External inspection is due by: 12/02/2023

4.8.3 Next UT inspection is due by:

5.0 ULTRASONIC THICKNESS (UT) MEASUREMENTS

5.1 Results Summary:

5.1.1 UT examination was performed on all the accessible tank and components to reveal no significant wall loss at the time of inspection.

5.2 Recommendations:

5.2.1 Thickness measurements should be taken during next scheduled inspection to monitor corrosion rates and tank integrity.

Minimum Thickness Determinations: Component tmin may be determined by any of the following as relative:

1) Components calculated per original design Ca as follows: tnom - Ca = t

2) Pipe components calculated per ASME B31.3, para. 304 as follows: PD/2(SE+PY) = t

3) PV cyl. components calculated per ASME Sect VIII, UG 27 as follows: PR/SE-0.6P = t

4) Components calculated per original code of construction, (ASME, API, et.)

Component Remaining Life Calculations:

Where:

Ca = Remaining corrosion allowance of the component under consideration, in inch.

Cr = Corrosion rate of the component under consideration, in inch/Yr.

tact = Minimum thickness measurement of the component under consideration, as recorded at the time of inspection, in inch.

tmin = minimum required thickness of component, at the maximum allowable loading , in inch.

tprev = previous thickness measurement of the component under consideration, as recorded at last inspection or nominal thickness if no previous thickness measurements, in inch.

RL = Estimated remaining life of the component under consideration, in year.

Y = Time span between thickness readings or age of the component if nominal thickness is used for tprev, in year.
