1.1 Shop Fabricated AST leak testing procedure

1.1.1 Consult the Steel Tank institute Recommended Practice R912, Installation Instructions for Shop Fabricated Stationary Aboveground Storage Tanks for Flammable, Combustible Liquids. Air shall not be used for a pressure test; an inert gas shall be used instead. The introduction of a gas containing oxygen (such as air) to a tank that has previously held petroleum liquid can pose an explosion hazard.

1.1.2 Vacuum testing of the interstice of double-wall or double-bottom tanks is an option. Refer to the Steel Tank Institute Recommended Practice R912, Installation Instructions for Shop Fabricated Stationary Aboveground Storage Tanks for Flammable, Combustible Liquids.

1.1.3 Leak testing of CE-ASTs that are listed and labeled as UL2085 shall be performed in accordance with the specific requirements (or the testing manual) of the manufacturer. The testing, which includes brand-specific vacuum and hydrostatic testing, shall be performed by a properly trained professional.

1.2 Portable containers leak testing procedure – Refer to DOT Sections 49 CFR 173.28 (Reuse, reconditioning and remanufacturing of packagings – mainly for drums) and Part 178 – 49 CFR Subpart O – Testing of IBC’s [Intermediate Bulk Container] (section 178.803 Testing and certification of IBC’s) and 49 CFR 180.605, (Requirements for periodic testing, inspection and repair of portable tank), or equivalent, for portable container testing and recertification. Electronic versions of these documents are available online.

1.2.1 See the definition of Leak Testing Methods (LTM) for more information:

· A point-in-time test method to determine if an AST is liquid-tight. Leak testing is not preventative; it provides an indication only of whether the AST’s integrity has already been breached. Therefore, it may only be used as a tank integrity measure or as a supplement to other inspection procedures. LTMs may include the following technologies:

· Gas pressure decay (includes vacuum decay)

· Gas pressure soap bubble testing

· Gas tracers (e.g., helium tracer)

· Soil tracers (chemical Marker)

· Mass measurement

· Level Measurement

· Hydrostatic test image3.emf

SP001 6th ed Formal External Checklist.docx

1 FORMAL EXTERNAL INSPECTION (FEI) GUIDELINES – FOR REFERENCE

1.1 General

1.1.1 FEI are to be performed by Certified Inspectors.

1.1.2 The following paragraphs describe minimum inspection guidelines. There are numerous AST configurations and components and it is the responsibility of the Certified Inspector to identify and properly inspect them to conform to the owner’s requirements, industry standards and regulatory requirements, as applicable. The inspector or the inspection company shall develop detailed checklists that identify, record, and document all aspects of each inspection.

1.1.3 Review prior formal and periodic inspections, repair alteration data, and records of functionality testing of alarms and equipment, before each inspection.

1.1.4 Record AST nameplate data, if available, and check the information included for accuracy against actual conditions. Verify that the properties of the contents of the AST conform to the standard to which it was built. Record AST data, inspection findings, and problems identified.

1.1.5 Inspect the fabrication of the AST against applicable industry standards.

1.1.6 Inspect the AST foundations for indications of settlement, cracking, exposed rebar, or general disrepair. Inspect for areas of wash-out and voids under the AST. Confirm that the ground is sloped away from the AST and that there is no soil resting against the side of the AST, covering parts of the shell or bottom extension. Inspect for standing water against the AST or the indication of drainage problems.

1.1.7 Visually inspect the condition of the AST’s supports. Severe cracking or spalling of concrete supports shall be noted and evaluated. If there are pad plates between the supports and the shell, inspect their condition. Inspect the supports to be sure that they are sitting securely on the foundation or grade. If the supports are welded to the shell, inspect the welds for visible signs of stress or deterioration.

1.1.8 Identify and record the type and condition of the secondary containment, spill control, and CRDM, if present.

1.1.8.1 Visually inspect the general condition of the containment area to ensure that it is in good condition and that there is not a breach in the containment structure. Note changes from the original design and installation information if available.

1.1.8.2 Inspect for foreign materials in the containment area. Inspect for liquid in the containment system and CRDM. If liquid is present, find the source and report findings. Record other ASTs or containers within the same containment area.

1.1.8.3 Verify that the drain valves are operable and in good condition. Report penetrations through the secondary containment that may compromise the integrity of the containment area. Report penetrations that are likely to lead to failure of the secondary containment should the liquid level of water or liquid rise to these penetrations.

1.1.9 Inspect and verify the operability of ancillary equipment, including the following items:

1.1.9.1 Visually inspect accessible piping, piping supports and piping connections for signs of stress or leakage, due to severe corrosion, rusted bolted connections, or other severe degradation.

1.1.9.2 Inspect normal and emergency vents and pressure/vacuum devices. Verify that the devices are of adequate size and capacity, operable, and in good condition. Refer to the device manufacturer’s literature, typical industry venting requirements, and other appropriate resources. Record the types and locations of these devices.

1.1.9.3 Inspect primary tank level gauge and secondary tank interstitial gauge for free movement and determine if the floats, guides, and attachments are in working order. Verify the liquid level gauge length is sized correctly for the tank diameter.

1.1.9.4 Inspect the secondary tank interstitial monitoring equipment where present. Where possible verify free movement of floats and attachments and external alarms. Note that prior to triggering any alarm, proper warnings need to be made to the tank owner.

1.1.9.5 Verify and inspect tank overfill prevention devices including high level alarms and high level shut off valves. It may not be possible to verify operability of all devices, but where possible verify equipment is functional and calibrated to the appropriate liquid levels within the tank.

1.1.10 Inspect the bonding and grounding system of the AST, if present. (Refer to NFPA 780 Standard for the Installation of Lightning Protection Systems, NFPA 77 Standard Practice on Static Electricity or other applicable standard.)

1.1.11 Inspect stairways, handrails, and platforms for broken welds, bent members, and corrosion.

1.1.12 Inspect the coating on the AST shell, and supports for coating failure.

1.2 Determine the original shell thickness of the AST. Suggested methods are:

1.2.1 Review the original tank documentation, such as drawings and packing lists.

1.2.2 Consult the tank manufacturer.

1.2.3 Examine the tank labels for evidence of a widely accepted tank standard, such as Underwriters Laboratories Standard UL 142, etc. Consult the referenced standard to determine the minimum design shell thickness.

1.2.4 Measure the tank thickness of several areas of the tank that have no visible corrosion or pitting. The average of these measurements will result in a shell thickness measurement that can be used as the original shell thickness measurement.

1.3 Horizontal AST Requirements - in addition to the applicable items in 1.1:

1.3.1 Inspect shell plates and welds for indications of exterior corrosion, buckling, or distortion, as well as for cracking, pinholes, or mechanical damage. Inspect the shell of the AST and the ancillary equipment for signs of distortion and stress.

1.3.1.1 Take and record UTT readings and the location of the reading of each plate or shell course in areas accessible without entering the AST. Readings must be concentrated in areas where corrosion is likely to occur. If significant internal corrosion is detected, further investigation using UTS is required. If applicable, include areas marked from previous readings. Refer to Section 10.0 of STI SP001.

1.3.1.2 Existence of external corrosion may require the use of a pit depth measurement device in addition to the UTT to determine the remaining wall thickness.

1.3.2 Inspect shell attachments for changes made after the AST was fabricated. Refer to previous drawings or make new sketches that show all the appurtenances, attachments, and nozzle locations on the AST shell and heads or roof. Record repads (reinforcing plates) and/or insert plates. Inspect attachment welds for signs of stress and corrosion.

1.4 Vertical or Rectangular AST Requirements - in addition to the applicable items in 1.1:

1.4.1 Shell surface – Refer to 1.3.1 and 1.3.2

measure thicknesses in previously measured areas for corrosion rate determination. If significant corrosion is detected, further investigation using ultrasonic testing scans (UTS) is required. Refer to Section 10.0 of STI SP001.

1.5 Double-wall and Double-bottom AST Requirements - in addition to the applicable items in 1.1:

1.5.1 Verify that the leak detection equipment or method is operating, if the tank is so equipped.

1.5.2 Check for leaks or the presence of liquid in the interstice. When liquid is present in the interstitial space of the AST, thickness measurements should be taken on the secondary tank. UTT and UTS shall be of sufficient quantity and location to verify adequate containment integrity of the secondary tank. If product is found in interstitial space, perform a leak test to determine if primary tank is tight.

1.5.3 Double-bottom ASTs require UTT readings of areas that are single-wall as described in paragraph 1.3.1.1 above. Double-wall ASTs do not require UTT readings for the primary tank. In addition, if corrosion is evident on the outside surface of the secondary tank, UTT readings are required.

1.6 Steel Diked AST Requirements - in addition to the applicable items in 1.1 to 1.4:

1.6.1 For open-top dikes, inspect the condition of the dike and determine if liquid is present. For closed-top dikes that are fitted with an access port, inspect the condition of the inside of the enclosed diked area and determine if liquid is present. AST modifications may be needed in order to provide access for additional assessment. If liquid has entered the space or conditions indicate corrosion could be causing a problem, further evaluation is required.

1.6.2 Ultrasonic thickness measurements shall be taken on the tank shell wherever accessible, such as above the rain shields and by removing rain shields to gain access within the dike area where possible.

1.6.3 Ensure tank systems are operated with spill and overfill protection controls. Ensure an emergency vent is present and functions for closed-top containment structures.

1.7 Insulated AST Requirements - in addition to the applicable items in 7.1 through 7.4, except as modified below:

1.7.1 Inspect the insulation material and outer jacket for indications of damage where water may be allowed to wick into the insulating layer. Specifically inspect for areas where water may be trapped behind or within the insulation. If any of the following conditions are identified, then remove sections of the insulation to check for corrosion:

· Evidence that the tank may be compromised,

· Evidence that the base of the tank is consistently in contact with standing water, or

· Insulation is significantly compromised and has not been repaired or replaced in a timely manner

1.7.2 If corrosion under the insulation is suspected, remove sections of the insulation to check for corrosion. Damage done to the insulation for the purpose of inspection shall be repaired.

1.7.3 Take UTT readings of the shell where accessible and where insulation is removed per 1.7.1 and record results. In addition, include, if applicable, areas marked from previous readings. If significant internal corrosion is detected, further investigation using ultrasonic testing scans (UTS) is required. Refer to Section 10.0 of STI SP001.

1.8 Concrete Exterior ASTs (CE-ASTs) Requirements - in addition to the applicable items in 1.1:

1.8.1 Follow the tank manufacturer’s instructions for inspection and maintenance.

1.8.2 Inspect concrete exterior body of the tank for cleanliness, need of coating, or rust staining.

1.8.3 Inspect the entire exterior of the tank for cracks in concrete.

· Cracks larger than 1/16 of an inch in thickness require repair.

· If cracks greater than 1/16 of an inch are present on all four top chamfer edges, then the tank shall be further evaluated and repaired in consultation with the tank manufacturer, due to the possibility of damage or over-pressurization of the secondary containment.

1.8.4 Check for leaks or the presence of liquid in the interstice. If liquid is found, then further investigation is needed to determine the cause.

1.8.5 Check the seal between the pipe nipples (and other tank top appurtenances) and concrete.

1.8.6 CE-ASTs with joints or seams in the concrete exterior require inspection of the joint seal for deterioration, holes, tears, and cracks.

1.9 Additional requirements for field-erected ASTs are included in Appendix B of STI SP001.

1.10 In the final report, include field data, measurements, pictures, drawings, tables, and an inspection summary. In the summary, identify unacceptable conditions and recommended and/or mandatory corrective actions. Determine the suitability for continued service of the AST per Section 10.0 of STI SP001 and document this in the final report. Include the date of the next scheduled FEI or FII, as applicable. Include the inspector’s name and certification number in the report.

SP001 6th ed Formal Internal Checklist.docx Formal Internal Inspection Guidelines

1.1 General

1.1.1 FII are to be performed by Certified Inspectors per STI SP001 requirements.

1.1.2 The following paragraphs describe bare minimum inspection guidelines. There are numerous AST configurations and components; it is the responsibility of the Certified Inspector to identify and properly inspect them to conform to the owner’s requirements and/or industry standards. The inspector or the inspection company shall develop detailed checklists that identify, record, and document all aspects of each inspection.

1.1.3 An FII includes the requirements of an FEI with the addition of the requirements described below.

1.1.4 For elevated ASTs where all external surfaces are accessible, the internal inspection requirements may be satisfied with an examination from the exterior by using such methods as UTS. For all other situations, entry into the interior of the AST is necessary to assess the condition of all surfaces.

1.2 Horizontal AST Internal Inspection

1.2.1 Identify, measure, inspect, and record all AST internal appurtenances. Inspect for mechanical damage, corrosion, cracking, ect. Inspect for deteriorating or corroding internal attachments or piping. Take thickness readings of internal structures and record the readings.

1.2.2 Inspect the welds for cracking by visual inspection or, if necessary, by magnetic particle (MT) inspection or equivalent method.

1.2.3 Internal NDT Inspection

1.2.3.1 Ultrasonic testing equipment that is capable of scanning the tank (UTS) rather than measuring only individual points (UTT), is the preferred method of testing. Personnel performing UTS are to be qualified per STI SP001 requirements. If ultrasonic testing equipment that is capable of scanning the tank is not practical, use equipment that tests individual points. In this case, take UTT measurements of at least 15 points per each 12”x12” (0.3x0.3 meters) square area of the shell that is in contact with the ground. Any questionable areas are to be assessed by UTS.

1.2.3.2 Perform a vacuum box (VB) examination of questionable welds to check for leaks.

1.2.3.3 Refer to STI SP001 criteria for suitability for continued service.

1.3 Vertical and Rectangular AST Internal Inspection

1.3.1 Identify, record, inspect, and measure all AST internal surfaces and appurtenances. Inspect AST internals to check for mechanical damage, corrosion, cracking, ect. Check for deteriorating or corroding internal attachments and piping. Take thickness readings of internal structures and record the readings.

1.3.2 Inspect the welds for cracking, corrosion, or incomplete fusion which may result in a leak by visual inspection. If additional investigation is needed, the weld may be tested using vacuum box (VB) or if necessary magnetic particle (MT) or liquid dye penetrant (DPT) inspection or equivalent method.

1.3.3 Internal NDT Inspection

1.3.3.1 AST floor thickness assessments is required as follows:

Complete coverage of the AST floor is recommended, due to random corrosion characteristics of metal in contact with the ground. Inspection of the AST floor is recommended using inspection methods capable of determining the underside floor condition, such as UTS, MFL followed by UTS of questionable areas, or other equivalent methods.

If ultrasonic testing equipment that is capable of scanning the tank is not practical, use equipment that tests individual points. In this case, take UTT measurements of at least 15 points per each 12”x12” (0.3x0.3 meters) square area of the shell that is in contact with the ground. Any questionable areas are to be assessed by UTS.

1.3.3.2 Perform a vacuum box (VB) examination of questionable welds to check for leaks.

1.3.4 Refer to STI SP001 criteria for suitability for continued service.

1.4 Additional requirements for field-erected ATSs are included in Appendix B.

1.5 Report – in the final report; include field data, measurements, pictures, drawings, tables, and an inspection summary. Identify in the summary unacceptable conditions and recommended and/or mandatory corrective actions. Determine the suitability for continued service of the AST per Section 10.0 and document this in the final report. Include the date of the next scheduled Formal External and or FII, as applicable. Include the inspector’s name and certification number in the report.
