California ICC UST Inspector Practice Exam

What is the maintenance requirement following the repair of UST tanks and piping?

1. Immediate disposal of equipment

2. Inspection immediately after repair

3. Testing for tightness within 30 days

4. Routine monitoring

The correct answer is: Testing for tightness within 30 days

Following the repair of underground storage tanks (USTs) and piping, it is essential to conduct testing for tightness within 30 days to ensure that the repairs were effective and that there are no leaks. This requirement is a critical part of maintaining environmental safety and compliance with regulations designed to protect groundwater and surrounding areas from potential contamination. Testing for tightness confirms that the repairs have restored the UST system to a condition that prevents the escape of regulated substances. Conducting this assessment within a specific timeframe ensures that any potential issues are identified and addressed promptly, thereby minimizing risks associated with leaks and spills. Moreover, while other options may be part of maintenance procedures, they do not address the specific need for verifying the integrity of the system post-repair as directly as tightness testing does. Immediate disposal of equipment does not align with maintenance practices; inspection right after repair might not provide enough evidence of system integrity; and routine monitoring is an ongoing practice but does not specifically follow repairs in the same manner as tightness testing.
