California ICC UST Inspector Practice Exam

Field-installed cathodic systems must be designed and certified by whom?

1. A trained and certified UST service technician

2. A state registered professional engineer

3. A corrosion specialist

4. A local agency inspector

The correct answer is: A corrosion specialist

Field-installed cathodic protection systems are essential for safeguarding underground storage tanks (USTs) from corrosion. The certification of these systems must be performed by a corrosion specialist because this individual possesses the specific knowledge and expertise necessary to design systems that effectively mitigate corrosion risks. Corrosion specialists are trained to understand the various factors that contribute to corrosion, including soil characteristics, moisture content, and the chemical properties of the substances being stored. The expertise of a corrosion specialist ensures that the cathodic protection system is properly designed and will function effectively in preventing corrosion over the lifespan of the UST. This is crucial not only for the longevity of the tank and its components but also for environmental safety and regulatory compliance. While trained UST service technicians and registered professional engineers may have relevant skills, their training may not be specifically focused on corrosion prevention methodologies and strategies. Local agency inspectors may oversee compliance and safety measures but do not typically engage in the design or certification of cathodic systems.
