Mechanical Integrity Testing and Inspection

Above Ground Tank Inspection Services

Owners/operators of petroleum-containing aboveground storage tanks (ASTs), may be subject to the Spill Prevention, Control and Countermeasures (SPCC) rule. This rule regulates facilities that have more than 1,320 gallons of total oil storage capacity.

There are many regulations that require inspection of aboveground tanks: SPCC rule is one of them, the RMP, Hazardous wastes, tiered permitting, fire codes also require inspection of tanks. The formal inspection requirements are set out in the facility’s SPCC plan and this applies to 55-gallon containers and above. The size is based upon shell capacity not how much you put in the container/tank.

Aboveground Tank Inspection Services:

  • STI SP001 – Steel Tank Institute: Standard for Inspection of In-Service Shop Fabricated Aboveground Tanks for Storage of Combustible and Flammable Liquid
  • API 653 – American Petroleum Institute: Atmospheric Welded or Bolted Above Ground Storage Tanks that were constructed to the API 650 standard or its predecessor, API 12C.
  • FTPI-2007-1 - Fiberglass Tank & Pipe Institute's Recommended Practice for the In-service Inspections of Aboveground Atmospheric Fiberglass Reinforced Plastic (FRP) Tanks and Vessels.
  • API 510 - Pressure Vessel Inspection Code: In-Service Inspection, Rating, Repair, and Alteration- The code covers inspection, repair, alteration, and rerating activities for pressure vessels and the pressure relieving devices that protect vessels covered by the code
  • D101-53: AWWA Recommended Practice for Inspecting and Repairing Elevated Steel Water Storage Tanks
  • NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems

These inspections must be carried out to applicable industry standards. If they are not, you are putting your business at risk and may be subject to remediation costs that cost a substantial amount of money. 

Aboveground storage tank inspections can be carried out by our organization, and these will be done so in a way that will match applicable requirements. Inspections will be carried out to the industry standards as outlined below:

Title 22 Hazardous Waste Tank Assessments

If you are classed as a large Quantity Generator of hazardous waste and you use aboveground tanks to store it, it is a requirement that you have your tanks looked at by a licensed professional engineer every 5 years. 

We can provide these assessments for you as well as certifications that these tank systems comply with the requirements laid out. Tank and containment certifications will be provided by a PE registered with the State of California.

This assessment will look at the tank and secondary containment tank and ensure it is adequately designed and constructed. The condition of the tanks will also be assessed, as well as the materials being used in the tanks, piping, secondary containment, seismic bracing, and more. 

Many local CUPA inspectors often overlook PE tank certification, especially the 5-year renewal requirement. However, CUPA inspectors are beginning to look more closely at this, so it must be taken care of and certified.
