The role of a Storage Tank System (STS) Inspector is critical in ensuring the safety and integrity of a facility's storage tank systems. The inspector is responsible for performing regular inspections of the tanks to detect any corrosion, holes, or other damages, as well as ensure proper maintenance and operation of any pumps, valves, and other equipment associated with the tanks. Any issues found can cause significant safety and environmental issues, such as oil spills or hazardous chemical exposures, making the regular inspection and maintenance of STSs essential.

The inspector must also be knowledgeable about applicable laws, regulations, and industry standards to ensure the facility is in compliance with all requirements. By regularly inspecting tanks and associated equipment, STS Inspectors ensure the safe and effective operation of the facility.

Steps How to Become

Obtain a high school diploma or equivalent. Many employers require a high school diploma or an equivalent, such as a GED, to become an STS Inspector.
Complete an apprenticeship program. Some employers may require prospective STS Inspectors to complete a formal apprenticeship program before starting work. This program may consist of both on-the-job and classroom training that covers topics such as occupational safety, storage tank system design, and inspection procedures.
Obtain certification. Although it is not required in all areas, some employers may prefer or require STS Inspectors to obtain certification. The National Institute for Storage Tank Management (NISTM) offers the Certified Storage Tank System Inspector (CSTS) certification, which is available after passing an exam.
Obtain a license. Depending on where you work, you may need to obtain a license to work as an STS Inspector. Contact your local government or the state licensing board to find out if a license is required in your area and to learn how to obtain one.
Gain experience. Many employers prefer to hire experienced STS Inspectors, so gaining experience in the field is important. Consider working as an apprentice or assistant STS Inspector to gain the experience you need to apply for a full-time position.

The Tank System (STS) Inspector is an important position that requires a high level of skill and qualification. To become a qualified STS Inspector, individuals must complete a specialized training program and demonstrate their knowledge of the STS regulations, design, and operations. This training includes passing an exam and demonstrating proficiency in inspecting and testing the STS components.

Once an individual has successfully completed the training, they are awarded a certification that allows them to work as an STS Inspector. Having a skilled and qualified STS Inspector on staff allows a facility to ensure that their storage tank system is compliant with state and federal regulations. This reduces the risk of costly fines and potential environmental damage due to improper maintenance or operation of the tank system, resulting in a safer and more efficient operation for everyone.

Effective communication skills to explain findings to clients in a clear and concise manner.

As a Storage Tank System (STS) Inspector, the most important skill to have is an extensive understanding of the regulations and standards that govern underground and aboveground storage tanks. This understanding allows the inspector to accurately assess tanks for compliance with regulations and standards, ensuring the safety of the public and the environment. In addition, having a detailed knowledge of the components and functions of tanks is essential for a successful inspection.

This includes knowledge of tank design, materials, and construction practices, as well as an understanding of how these components interact and affect the system as a whole. Finally, it is important for inspectors to be familiar with the methods used to monitor tank systems and detect potential problems, such as leak detection and corrosion monitoring. With these skills and knowledge, a STS Inspector can competently perform their duties and ensure the safety of the public and environment.
