Our tank services are unequaled in Massachusetts. We've been designing, building, installing, repairing, removing and inspecting them for 26 years. So we know first-hand how a tank's condition evolves over time—experience only a full-service company like CommTank can offer.

CommTank is also one of just a handful of companies in Massachusetts with a qualified tank inspector who is API 653-certified by the American Petroleum Institute® and STI SP001 Certified by the Steel Tank Institute. That's important. Because your permit to operate an AST hinges on complying with Massachusetts' law requiring annual inspections by a certified inspector. It applies to any AST that holds over 10,000 gallons of fluid other than water.

The following video shows the steps required to perform aboveground storage tank inspections utilizing both Magnetic Flux Leakage (MFL) scanner and Ultrasonic Test (UT) equipment.

Municipal fire codes generally mandate minimum requirements for fire protection storage tank inspection programs in accordance with National Fire Protection Association (NFPA) 25. NFPA 25 requires external AST inspections every 3 years and internal AST inspections every 5 years for water-based aboveground storage tank systems. Insurance policy conditions also reference NFPA 25 and may recommend a more frequent inspection cycle.

Our Tank Inspection Licenses

  • API 653 – American Petroleum Institute AST Inspector

We realize our reputation is on the line with every inspection we perform. Our goal is to give you the peace of mind of knowing your tanks have received a complete inspection and areas of concern are noted. With every inspection, we provide a report detailing what was inspected, what passed and failed, and photographs of problem areas. We also give you a written statement about our findings for your tank's interior and exterior. Our ultimate goal is to keep you compliant with Massachusetts' tank laws (502 CMR 5) and you and your employees safe.

  • Chemical Storage Tanks

Tank Inspection Keeps You Compliant

CommTank makes it easy to stay compliant with state laws by scheduling annual inspections for you. This also drastically reduces your risk of fines from other regulatory agencies and keeps tank maintenance costs to a minimum.

How We Inspect

For internal inspections, the storage tank must be taken out of service, cleaned, and made ready for the inspector to enter the tank.

Integrity tests we perform:

  • Visual inspection
  • Ultrasonic Thickness Testing
  • Magnetic Flux Leakage (MFL) scan
  • Hydrostatic testing
  • Inert gas leak testing 

Potable water storage tank inspections are performed while the tank is in service using our Remotely Operated Vehicle (ROV).

In situations where storage tank roof access is limited we provide visual inspections using an aerial drone.
